First embodiment

Referring to fig. 1, a schematic diagram of the overall structure of the LED display screen according to the first embodiment after the installation is completed is shown. The mounting structure of the LED display screen in this embodiment is divided into two parts, wherein one part is connected to the back surface of the LED display screen 100, and the other part is connected to the member to be mounted 200. The to-be-installed part 200 may be an installation box, a wall, or the like.

Specifically, as shown in fig. 4 to 6, the mounting structure of the LED display 100 includes a first fixing plate 410, a first clamping member 420, a push rod 430, an elastic member 440, a stopper 450, a stopper 460, and the like. The first fixing plate 410 is fixed to the rear surface of the LED display screen 100 by a screw fastener. One end of the first clamping member 420 is hinged to the first fixing plate 410, and the first clamping member 420 can rotate relative to the first fixing plate 410 with the hinged portion as a center. The first clamping piece 420 is provided with a concave portion 421 for being in snap connection with the mounting structure on the piece 200 to be mounted.

The elastic member 440 is v-shaped and includes a first elastic piece 441 and a second elastic piece 442 that are integrally connected, the first elastic piece 441 is fixedly connected with the first fixing plate 410 through a threaded fastener, and the second elastic piece 442 is fixedly connected with the first clamping member 420 through a threaded fastener. Since one end of the first clamping member 420 is fixedly connected with the elastic member 440 and the other end is hinged with the first fixing plate 410, the elastic member 440 will be stretched or compressed when the first clamping member 420 rotates relative to the first fixing plate 410, so that the first clamping member 420 elastically rotates relative to the first fixing plate 410, i.e. elastically rotates relative to the LED display screen 100. In addition, the elastic member 440 may be a spring or other elastic member. However, preferably, the v-shaped elastic piece in the embodiment is selected as the elastic piece, and compared with the spring, the second elastic piece 442 and the first clamping piece 420 in the embodiment are in surface contact, so that the stability is higher, and the torsion is not easy to occur in the compression process.

The push rod 430 is also hinged to the first fixing plate 410 and is rotatable with respect to the first fixing plate 410. And the first push rod 430 is provided with a plurality of teeth 431. The stopper 450 and the blocking post 460 are fixedly connected with the first fixing plate 410. The elastic member 440 and the stopper 450 are respectively located at two sides of the first locking member 420, and when the first locking member 420 elastically rotates relative to the first fixing plate 410, the first locking member will abut against the stopper 450.

As shown in fig. 6, the LED display 100 is further provided with a through hole for passing the force application tool 500, and after the force application tool 500 passes through the through hole, an end portion thereof can contact the push rod 430, so that the force application tool 500 is pushed to rotate the push rod 430 clockwise. The through holes need to avoid the important components on the LED display screen 100, so as to avoid affecting the normal display of the LED display screen 100.

As shown in fig. 2,3 and 6, the part of the mounting structure located on the to-be-mounted member 200 includes a second clamping member 310, a second fixing plate 320, a supporting member 330, a ratchet 340, a pawl 350 and other components. The second clamping member 310 and the second fixing plate 320 are both fixedly connected to the to-be-installed member 200. The second clamping piece 310 is provided with a protruding portion 311 for being in snap connection with the first clamping piece 420 on the LED display screen 100. The holder 330 is hinged to the second fixing plate 320, and is rotatable with respect to the second fixing plate 320. Both the ratchet 340 and the pawl 350 are coupled to the second fixing plate 320, and the ratchet 340 is engaged with the pawl 350 such that the ratchet 340 can only rotate in one direction. The ratchet 340 and the pawl 350 are located on a first side of the second fixed plate 320, and the abutment 330 is located on a second side of the second fixed plate 320.

The mounting process of the LED display screen is explained as follows with reference to fig. 6 to 8. As shown in fig. 7, the back surface of the LED display 100 is close to the to-be-mounted member 200, so that the protruding portion 311 on the second clamping member 310 is aligned with the recessed portion 421 on the first clamping member 420. And presses the LED display 100 toward the to-be-mounted member 200 so that the protruding portion 311 gradually snaps into the recessed portion 421. As shown in fig. 8, during the pressing process, the first clamping member 420 is rotated counterclockwise by a certain angle by the pressing of the second clamping member 310. When the first locking member 420 rotates, the elastic member 440 is pressed to be in a compressed state. In this process, the first locking member 420 will abut against the stopper 450, and the stopper 450 provides a fulcrum for the rotation of the first locking member 420. As shown in fig. 6, after the protruding portion 311 is completely clamped into the recessed portion 421, the first clamping member 420 will rotate clockwise to return to the original position under the resilience force of the elastic member 440 and abut against the stop 450, and the elastic member 440 and the stop 450 limit the first clamping member 420, so that the clamping is more stable. At this time, the first clamping member 420 will hang on the second clamping member 310, so that the LED display screen 100 is hung on the to-be-mounted member 200. In order to improve the stability of the mounting, a plurality of sets of mounting structures may be provided, and in this embodiment, four sets of mounting structures are provided, and the number of mounting structures may be adjusted according to the area and weight of the LED display screen, without being limited thereto in practice.

The process of removing the LED display screen is explained as follows with reference to fig. 9 to 11. As shown in fig. 9, when the LED display 100 needs to be removed for replacement or repair, the force application tool 500 is inserted through the through hole of the LED display 100, and the tip of the push rod 430 is pushed by the front end of the force application tool 500. The push rod 430 is rotated clockwise by the pushing of the force application tool 500, and the bottom end thereof is contacted with the first clamping member 420. As shown in fig. 10, when the force application tool 500 is pushed continuously and the rotation range of the push rod 430 is larger, the top end of the push rod 430 will abut against the top of the abutting piece 330, the bottom end abuts against the first clamping piece 420, and the abutting piece 330 acts as a "lever" to tilt the first clamping piece 420 to rotate anticlockwise. When the first locking member 420 rotates counterclockwise, it will abut against the elastic member 440, so as to be in a compressed state. As shown in fig. 11, when the first locking member 420 is rotated to a certain extent, the protruding portion 311 is separated from the recessed portion 421, and the LED display 100 is completely detached. After the disassembly is completed, the force application tool 500 is withdrawn, and the first clamping member 420 rotates clockwise to reset under the resilience force of the elastic member 440, and drives the push rod 430 to rotate anticlockwise to reset. In this embodiment, by providing the push rod 430, the LED display 100 can be detached more easily, and the force application tool 500 can be directly inserted from the front of the LED display 100 to push the push rod 430. This is easily accomplished because the front surface of the LED display 100 is exposed.

Preferably, since the supporting member 330 is rotatably connected to the second fixing plate 320, the top end of the supporting member 330 will rotate clockwise after being supported by the push rod 430, and the bottom end thereof will extend outwards to support the blocking post 460, so that the blocking post 460 is pushed outwards, and the protruding portion 311 is more easily separated from the recessed portion 421.

Preferably, reverse rotation of the push rod 430 during disassembly is also prevented by the ratchet 340 and pawl 350. The teeth 431 on the push rod 430 engage the ratchet wheel 340, and during disassembly, when the push rod 430 rotates clockwise, the ratchet wheel 340 engaging the teeth 431 rotates counterclockwise. Since the elastic member 440 is in a compressed state during the disassembly process, it has a rebound tendency, if the force application tool 500 is released briefly, the first locking member 420 is rotated and reset clockwise due to the rebound of the elastic member 440, so that the push rod 430 is rotated and reset counterclockwise. However, due to the ratchet 340 and the pawl 350, the ratchet 340 can only rotate counterclockwise, and if the push rod 430 rotates counterclockwise, the ratchet 340 cannot engage with the teeth 431 on the push rod 430 and cannot rotate clockwise, so that the reset of the push rod 430 is inhibited, and the disassembly work cannot be completed. Because of the ratchet 340 and the pawl 350, the force applied by the force application tool 500 does not need to be continuously applied, so that the force application person is not tired.

The embodiment also provides an LED display screen system, which comprises the mounting structure of the LED display screen, and further comprises the LED display screen 100 and the to-be-mounted piece 200, wherein the mounting structure can be used for dismounting the LED display screen 100 and the to-be-mounted piece 200.

Second embodiment

The present embodiment is an alternative embodiment to the first embodiment, and in the present embodiment, the mounting structure includes only the first clamping member 420, the second clamping member 310, and the push rod 430. The first clamping piece 420 is directly and fixedly connected with the LED display screen 100, and cannot rotate relative to the LED display screen 100, and the first clamping piece 420 has certain elasticity. However, in this case, when the push rod 430 is pushed, the protruding portion 311 is separated from the recessed portion 421 with a great difficulty, and the first locking member 420 and the second locking member 310 are easily damaged.

Third embodiment

This embodiment is an alternative embodiment to the first embodiment in which the ratchet 340 and the pawl 350 are not required. However, in this case, the removal process is unstable, and the push rod 430 may be reversely moved by the resilience of the elastic member 440, so that the protrusion 311 is re-engaged into the recess 421, and the removal cannot be completed.

Fourth embodiment

In this embodiment, the retaining member 330 is directly and fixedly connected to the second fixing plate 320 without the need of the retaining post 460, and the push rod 430 abuts against the top of the retaining member 330 when rotating. In this case, however, the difficulty of separating the convex portion 311 from the concave portion 421 is large.

Fifth embodiment

The present embodiment is an alternative embodiment to the first embodiment, in this embodiment, a protruding portion is disposed on the first clamping member 420, and a recessed portion is disposed on the second clamping member 310. Or the first clamping piece 420 is provided with a protruding part and a recessed part, and the second clamping piece 310 is provided with a recessed part matched with the first clamping piece 420 and a protruding part matched with the first clamping piece 420.

Sixth embodiment

This embodiment is an alternative embodiment to the first embodiment, in which the position where the push rod 430 rotates with respect to the LED display screen 100 is referred to as a rotation center, such that the distance between the rotation center and the first end of the push rod 430 is greater than the distance between the rotation center and the second end of the push rod 430. By this arrangement, the push rod can be made into a labor-saving lever, and the first clamping member 420 can be separated from the second clamping member 310 by applying a small force during the disassembly.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention. Furthermore, embodiments of the invention and features of the embodiments may be combined with each other without conflict.
