Detailed Description
The technical scheme of the application is further described below by the specific embodiments with reference to the accompanying drawings.
Example 1
As shown in fig. 1 to 8, a latex elastic body length adjustment locking device includes a housing 1, a length adjustment mechanism and a locking mechanism. The shell 1 is provided with a hook mounting part 14, and the hook mounting part 14 is used for mounting a hook. The free end of the latex tube passes through the shell 1 first and then is provided with a limiting piece, such as a limiting bead, the other end of the latex tube is provided with a clamping hook, and the clamping hook can be detachably connected with the handle or other auxiliary exercise tools, so that the latex tube has wide applicability.
The length adjusting mechanism comprises a main adjusting assembly and a secondary adjusting assembly which are symmetrically arranged. The main adjusting assembly comprises a driving gear 21, a main cam 22 axially eccentrically connected with the driving gear 21, and a driving shaft 23 connected with the central shaft of the driving gear 21. The secondary adjusting assembly comprises a driven gear 31, a secondary cam 32 which is eccentrically connected with the driven gear 31 in the axial direction, and a support shaft 33 which is connected with the central shaft of the driven gear 31. The driving gear 21 is engaged with the driven gear 31, and a gap allowing the free end of the latex tube to pass through is formed between the main cam 22 and the sub cam 32. The casing 1 is provided with an inner cavity for accommodating the length adjusting mechanism, a latex elastomer inlet 11 communicated with the inner cavity, and a latex elastomer outlet 12 communicated with the inner cavity, namely, the free end of the latex tube enters from the latex elastomer inlet 11 and then passes through a gap and is extracted from the latex elastomer outlet 12.
The gap shown in the figure is the minimum gap formed by the primary cam 22 and the secondary cam 32, at which time the latex tube is clamped. The driving shaft 23 is located at the center of the driving gear 21, so that the lengths of the edges of the driving shaft 23 and the driving gear 21 are equal, and the gap adjustment only needs to rotate part of the driving gear 21 by an angle of 120 degrees, so that the rest edges of the driving gear 21 can be removed, on one hand, the material can be saved, the cost can be reduced, on the other hand, the volume can be reduced, and the device can be optimized. The driving shaft 23 is located at the middle lower position of the main cam 22, that is, the driving shaft 23 is located below the central shaft of the main cam 22, so that when the driving gear 21 drives the main cam 22 to rotate clockwise, the length from the driving shaft 23 to the edge right above the main cam 22 is continuously reduced, the gap is continuously increased, the position of the driving shaft 23 is unchanged during rotation, and when the driving shaft rotates clockwise for 120 degrees, the gap is maximum, and the length adjustment of the latex tube is also easiest. Of course, because the pipe diameter of the latex pipe can be changed, when the pipe diameter of the latex pipe is smaller, the length can be adjusted without rotating to the maximum gap, and the specific use process can be adjusted according to actual conditions. The secondary adjustment assembly is similar in structure and operation.

The installation shell 6 is provided with a pawl accommodating cavity, the bottom of the installation shell 6 is provided with a pawl head inlet and outlet communicated with the pawl accommodating cavity, the bottom in the pawl accommodating cavity is provided with a spring connecting surface matched with the spring connecting block 53, and the installation shell 6 is also provided with a moving groove for the shifting block 54 to move up and down. The locking mechanism is used for preventing the driving gear 21 from rotating and ensuring that the main cam 22 is locked against rotation.
The length adjusting process of the latex tube comprises the following steps that firstly, a shifting block 54 is moved to the other end of a moving groove, at the moment, a pawl head 52 is retracted into a pawl head inlet and outlet, and a hand continues to press the shifting block 54 to be not loosened; step two, rotating the knob 4 clockwise to a proper position, loosening the hand pressing the shifting block 54, and enabling the pawl head 52 to extend out of the pawl head inlet and outlet and clamp into the corresponding tooth slot 41 under the action of the spring; step three, drawing the latex tube to adjust the length of the latex tube; step four, the shifting block 54 is moved to the other end of the moving groove, at the moment, the pawl head 52 is retracted into the pawl head inlet and outlet, and the hand continues to press the shifting block 54 and is not loosened; step five, the knob 4 is rotated anticlockwise to the extreme end, the hand for pressing the shifting block 54 is loosened, and the pawl head 52 extends out of the pawl head inlet and outlet under the action of the spring and is clamped into the corresponding tooth slot 41 to lock the knob 4.
