Detailed ways

The foregoing and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the accompanying drawings.

Referring to Fig. 1 and Fig. 2, a preferred embodiment of the tool-free coupling device 100 of the present invention is applied to the main body casing of a desktop computer, and can accommodate and position a fixed part (such as a peripheral device). Among them, an optical disc drive 5 is taken as an example for the peripheral equipment, and the opposite sides of the optical disc drive 5 are respectively provided with a plurality of fixing holes 51 originally designed for screw locks, and the main body casing includes a frame body 4, which forms a There is a support wall 41 and a second support wall 42 parallel to the support wall 41 at intervals, the distance between the support wall 41 and the second support wall 42 is to match the width of the optical disk drive 5, so that A space for the optical disc drive 5 is formed, and the support wall 41 is punched with a plurality of through holes 411 for aligning the fixing holes 51 of the optical disc drive 5 .

The combination device 100 includes a base 1 and a clamping unit.

The base 1 includes a body 11 and two insertion portions 12 protruding from the body 11 . The main body 11 has a first surface 111 facing the supporting wall 41, a second surface 112 opposite to the first surface 111, and an accommodating hole 113 passing through the first surface 111 and the second surface 112, and the insertion part 12 is The columns protrude from the first surface 111 , and are disposed corresponding to the through holes 411 of the support wall 41 , so as to be inserted into the fixing holes 51 of the optical disc drive 5 through the corresponding through holes 411 .

The locking unit includes a locking member 2 pivotally positioned on the body 11 of the base 1 and a buckling portion connected to the support wall 41 .

The engaging part 2 is composed of an interference part 21 exposed on the first surface 111 of the body 11 and a torsion part 22 exposed on the second surface 112 of the body 11. The interference part 21 is a rectangular plate body, which is used to In order to interfere with the fastening portion (described later), the twist portion 22 has a turntable 221 and a vertical plate 222 protruding from the rotary plate 221 toward the side away from the main body 11. The role of the vertical plate 222 is to provide the user's finger grip To twist the whole torsion part 22, in addition, the interference part 21 and the torsion part 22 are combined by a connecting part 23, in this example, the connecting part 23 has a turntable 221 that is connected and protrudes from the torsion part 22 and is close to the side of the main body 11 The positioning wall 231 and an L-shaped fitting hook 232 connected to the interference part 21 are formed on the side of the positioning wall 231 near the turntable 221 to form a fitting gap 233 for the corresponding fitting hook 232 to be combined. When the hook 232 and the embedding notch 233 are combined in the accommodation hole 113 of the body 11, the engaging member 2 can be positioned in the accommodation hole 113, and the interfering part 21 can rotate synchronously with the twisting part 22, and in a The length direction of the interfering part 21 changes between the connection position (as shown in FIG. 5 ) when the length direction of the interference part 21 is the upright direction, and the release position (as shown in FIG. 4 ) when the length direction of the interference part 21 is the horizontal direction. In addition, in order to increase the stability of the combination of the fitting hook 232 and the fitting notch 233, in this example, two locking walls 234 in the same protruding direction as the positioning wall 231 are provided at the center of the turntable 221, so that the two locking A space is defined in the middle of the wall 234, and a through hole 235 is provided through the corresponding position of the interference part 21, allowing a screw (not shown) to pass through the through hole 235 from the interference part 21 and locked in the two parts. Between the locking walls 234 , the effect of stably combining the interfering portion 21 and the twisting portion 22 is achieved.

The fastening part has two hook plates 3 that protrude from the support wall 41 and are opposite to each other at intervals up and down. The side shape is L-shaped. In this example, it is formed from the support wall 41 by punching. A buckle space 31 and a transverse gap 32 connected with the buckle space 31, and the width of the vertical direction formed by the gap 32 is the length of the rectangular plate that matches the interference part 21, and cannot pass through when the length direction is in the upright direction The gap 32 is used to enter and exit the fastening space 31 , and vice versa, when the length direction is in the horizontal direction, it can pass through the gap 32 .

When assembling the optical disc drive 5, first align the fixing hole 51 of the optical disc drive 5 with the perforation 411 on the support wall 41, and rotate the engaging member 2 relative to the body 11 of the base 1 to the release position, and then place the base The seat 1 and the engaging member 2 approach the supporting wall 41, so that the socket portion 12 of the base 1 passes through the through hole 411 and is inserted into the fixing hole 51 of the optical disc drive 5, so that the optical disc drive 5 and the supporting wall 41 are positioned mutually. At the same time, the interfering part 21 can also pass through the gap 32 formed by the two hook plates 3 and enter the buckle space 31 (refer to FIG. 4 ), and then the user can turn the twist part 22 of the engaging part 2 by about 90 degrees by hand. degrees, so that the interfering portion 21 rotates synchronously to the connecting position (refer to FIG. 5 ), so that the length of the interfering portion 21 is in the upright direction and cannot be positioned in the buckling space 31 formed by the two hook plates 3 through the gap 32, In this way, the base 1 will be fixed on the supporting wall 41 and will not fall off, and because the socket portion 12 of the base 1 is inserted into the fixing hole 51 of the optical disc drive, the optical disc drive 5 is stably fixed on the frame body 4 superior.

On the contrary, when the optical disk drive 5 is to be disassembled from the frame body 4, the user then reversely turns the twisted part 22 of the engaging part 2 with bare hands, so that the interfering part 21 reaches the release position and can pass through the gap formed by the two hook plates 3 32 o'clock, the base 1 can be taken off from the support wall 41 together with the engaging part 2, and after the insertion part 12 of the base 1 breaks away from the fixing hole 51 of the optical disc drive 5, the optical disc drive 5 can be removed from the frame body 4 out.

Referring to Fig. 1 and Fig. 2 again, in order to make the base 1 have a certain orientation when combined on the support wall 41, this example also has a fool-proof design, that is, the first surface 111 of the body 11 of the base 1 is respectively equipped with A pair of first positioning pins 114 and a pair of second positioning pins 115 are symmetrically protruding from the center of the hole 113 on the opposite sides of the horizontal direction. The distance between the first positioning pins 114 is relatively large, and the second positioning pins 115 The spacing distance is relatively small, and the support wall 41 is correspondingly provided with two first positioning holes 412 for inserting the first positioning pin 114, and correspondingly provided with two holes for inserting the second positioning pin 115. The second positioning hole 413, because the spacing of the first positioning pin 114 (first positioning hole 412) is not the same as the spacing of the second positioning pin 115 (second positioning hole 413), therefore, when combined, the base 1 It is bound to be able to be combined with the support wall 41 only when the first positioning pin 114 is on the top and the second positioning pin 115 is on the bottom. When 114 is in the downward position, it cannot be combined with the first positioning hole 412 and the second positioning hole 413 due to the difference in distance, so that the base 1 cannot be positioned on the support wall 41 . This design ensures that the assembly orientation of the base 1 and the support wall 41 is the same every time, and the rotation direction when the user rotates the engaging member 2 to the connection position or the release position can also remain the same, without having to adjust the assembly of the base 1 There are different rotation directions depending on the orientation, which increases the convenience of use. Of course, this fool-proof design is not necessary, or only a single positioning pin can be designed on the body 11 of the base 1. At this time, the positioning pin will only serve as the positioning between the body 11 of the auxiliary base 1 and the supporting wall 41. effect, not fool-proof.

In addition, as shown in Figures 2 and 3, in order to facilitate the user to reach the release position or the connection position when rotating the engaging part 2, the body 11 of the base 1 is also partially hollowed out to form two elastic arms 116, each elastic The free end of the arm 116 is formed with a positioning protrusion 117 protruding from the surface of the elastic arm 116, and the side of the rotating disk 221 of the twisting part 22 of the engaging member 2 close to the base 1 is formed with corresponding positioning protrusions 117 for locking. Two first recessed holes 223 and two second recessed holes 224, so that the position of the first recessed hole 223 is just the position where the interference part 21 is located at the release position and engages with the positioning convex part 117, while the second recessed hole 224 is exactly It is the position where the interfering part 21 is engaged with the positioning convex part 117 when the interfering part 21 is at the connecting position. Therefore, when the user rotates the engaging part 2 to the position where the first concave hole 223 and the positioning convex part 117 form a locked position, it can naturally Feel the resistance when turning to know that the engaging member 2 has reached the release position. On the contrary, when the second concave hole 224 and the positioning convex portion 117 form a stagnation, it will reach the connecting position, which is convenient for the user to rotate to the positioning position at one time. effect.

1 and 6, in actual use, the combination of the second support wall 42 and the optical disc drive 5 can be assembled using the same combination device 100 as described above, but in order to reduce the number of settings of the combination device 100, use The second supporting wall 42 is provided with a plurality of elastic elastic pieces 421 which are deflected toward the supporting wall 41. The elastic pieces 421 are to contact the corresponding side of the optical disk drive 5 when the optical disk drive 5 is assembled, and can be pushed by the optical disk drive 5. Squeeze, and after the elastic piece 421 is slightly deformed, an elastic restoring force is generated, which can provide the force for the optical disk drive 5 to abut against the supporting wall 41, so that the fixing hole 51 of the optical disk drive 5 and the socket part 12 of the base 1 are closely engaged. , and at the same time absorb the impact force generated when the optical disc drive 5 is shaken relative to the frame body 4 , so that the optical disc drive 5 can be assembled using a single coupling device 100 .

To sum up the above, the tool-free coupling device 100 of the present invention and the computer mainframe housing using the coupling device 100 can selectively make the base 1 assemble or separate from the supporting wall by operating the rotation orientation of the engaging part 2 with the user's bare hands. 41, and when the insertion part 12 of the base 1 is inserted into the fixing hole 51 of the fixed part through the through hole 411 of the supporting wall 41 to form an interference positioning effect, and make the engaging part 2 lock the position of the base 1, That is, the fixed part can be firmly combined with the frame body 4, so no matter whether it is assembled or disassembled, the user can complete it completely without the aid of tools, so the purpose of the present invention can indeed be achieved.

However, what is described above is only a preferred embodiment of the present invention. Although the foregoing description has specifically specified the detailed structure of the engaging part and the engaging part of the engaging unit, in fact, different form designs can be carried out as required, so when The implementation scope of the present invention cannot be limited by this, and all simple equivalent changes and replacements made according to the claims of the present application and the content of the description of the invention shall still fall within the scope covered by the patent of the present invention.
