First embodiment

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

Specifically, as shown in fig. 4 to 6, the mounting structure located on the back surface of the LED display screen 100 includes a first fixing plate 410, a first clip 420, a push rod 430, an elastic member 440, a stopper 450, a stop column 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 clip 420 is hinged to the first fixing plate 410, and the first clip 420 can rotate relative to the first fixing plate 410 with the hinged position as a circle center. The first clip member 420 is provided with a recess 421 for being connected with the mounting structure of the member to be mounted 200 by a snap fit.

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 to the first fixing plate 410 through a threaded fastener, and the second elastic piece 442 is fixedly connected to the first engaging member 420 through a threaded fastener. Because one end of the first clamping member 420 is fixedly connected with the elastic member 440, and the other end of the first clamping member 420 is hinged to the first fixing plate 410, when the first clamping member 420 rotates relative to the first fixing plate 410, the elastic member 440 will be stretched or compressed, so that the first clamping member 420 elastically rotates relative to the first fixing plate 410, that is, 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 sheet in this embodiment is used as the elastic member, and compared with the spring, the second elastic sheet 442 and the first clip member 420 in this 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 to be rotatable with respect to the first fixing plate 410. And a plurality of teeth 431 are arranged on the first push rod 430. The stop 450 and the stop pillar 460 are both fixedly connected to the first fixing plate 410. The elastic member 440 and the stopper 450 are respectively located at two sides of the first engaging member 420, and when the first engaging member 420 elastically rotates relative to the first fixing plate 410, the first engaging member will abut against the stopper 450.

As shown in fig. 6, the LED display panel 100 is further provided with a through hole for allowing the force application tool 500 to pass through, and after the force application tool 500 passes through the through hole, an end portion thereof can contact the push rod 430, and the force application tool 500 is pushed to rotate the push rod 430 clockwise. The through holes need to avoid important parts 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, fig. 3 and fig. 6, the mounting structure of the part on the member to be mounted 200 includes a second clamping member 310, a second fixing plate 320, a holding member 330, a ratchet 340, a pawl 350 and the like. The second clamping member 310 and the second fixing plate 320 are both fixedly connected to the member to be mounted 200. The second clip 310 is provided with a protrusion 311 for being connected with the first clip 420 on the LED display screen 100 in a snap-fit manner. The supporting member 330 is hinged to the second fixing plate 320 and can rotate relative to the second fixing plate 320. The ratchet gear 340 and the pawl 350 are connected to the second fixing plate 320, and the ratchet gear 340 is engaged with the pawl 350 such that the ratchet gear 340 can rotate only in one direction. The ratchet gear 340 and the pawl 350 are located on a first side of the second fixing plate 320, and the holding member 330 is located on a second side of the second fixing plate 320.

Referring to fig. 6 to 8, the mounting process of the LED display panel will be explained as follows. As shown in fig. 7, the back surface of the LED display screen 100 is close to the member to be mounted 200, so that the protrusion 311 of the second clip member 310 is aligned with the recess 421 of the first clip member 420. And the LED display screen 100 is pressed toward the member to be mounted 200, so that the convex portion 311 is gradually caught in the concave portion 421. As shown in fig. 8, during the pressing process, the first snap member 420 rotates counterclockwise by a certain angle under the pressing of the second snap member 310. When the first latch 420 rotates, the elastic member 440 is pressed to be in a compressed state. In this process, the first latch 420 will abut against the stop 450, and the stop 450 provides a pivot point for the rotation of the first latch 420. As shown in fig. 6, after the protrusion 311 is completely clamped into the recess 421, the first clamping member 420 will rotate clockwise to reset under the action of the resilience of the elastic member 440, and abut against the stopper 450, and the elastic member 440 and the stopper 450 limit the first clamping member 420, so that the clamping is more stable. At this time, the first clip 420 will be hung on the second clip 310, thereby hanging the LED display screen 100 on the member to be mounted 200. In order to improve the stability of the installation, a plurality of sets of installation structures may be provided, and in this embodiment, four sets of installation structures are provided, but in fact, the number of installation structures may be adjusted according to the area and weight of the LED display screen.

With reference to fig. 9 to 11, the procedure for detaching the LED display panel will be described as follows. As shown in fig. 9, when the LED display panel 100 needs to be removed for replacement or maintenance, the force application tool 500 is inserted through the through hole of the LED display panel 100, and the tip of the push rod 430 is pushed by the front end of the force application tool 500. Under the pushing of the force application tool 500, the push rod 430 will rotate clockwise, and the bottom end thereof will contact with the first clamping member 420. As shown in fig. 10, when the force application tool 500 is continuously pushed, when the rotation amplitude of the push rod 430 is larger, the top end of the push rod 430 abuts against the top of the abutting member 330, the bottom end abuts against the first engaging member 420, and the abutting member 330 acts as a "lever" to tilt the first engaging member 420, so that the first engaging member 420 rotates counterclockwise. When the first engaging member 420 rotates counterclockwise, it will be pressed against the elastic member 440, so that it is in a compressed state. As shown in fig. 11, when the first latch 420 rotates to a certain degree, the protrusion 311 will be disengaged from the recess 421, and the LED display screen 100 is completely disassembled. After the disassembly is completed, the force application tool 500 is withdrawn, and under the effect of the resilience force of the elastic member 440, the first clamping member 420 rotates clockwise to reset and drives the push rod 430 to rotate counterclockwise to reset. In this embodiment, the push rod 430 is provided, so that the LED display screen 100 can be more easily detached, and the force application tool 500 is directly inserted from the front surface of the LED display screen 100 and pushes the push rod 430. This is easy to achieve since the front of the LED display screen 100 is exposed.

Preferably, since the holding member 330 is rotatably connected to the second fixing plate 320, the top end of the holding member 330 will rotate clockwise after being held by the pushing rod 430, and the bottom end thereof will extend outward to be held on the blocking pillar 460, pushing the blocking pillar 460 outward, so that the protrusion 311 is more easily separated from the recess 421.

Preferably, the reverse rotation of the push rod 430 during disassembly is also prevented by the ratchet gear 340 and the pawl 350. The teeth 431 of the push rod 430 are engaged with the ratchet gear 340, and when the push rod 430 rotates clockwise during the disassembly process, the ratchet gear 340 engaged with the teeth 431 rotates anticlockwise. Since the elastic member 440 is in a compressed state during the detachment process, it has a rebound tendency, and if the force application tool 500 is released briefly, the first latch 420 is reset by clockwise rotation due to the rebound of the elastic member 440, so that the push rod 430 is reset by counterclockwise rotation. However, due to the existence of the ratchet wheel 340 and the pawl 350, the ratchet wheel 340 can only rotate counterclockwise, and if the push rod 430 tends to rotate counterclockwise, the ratchet wheel 340 cannot be engaged 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 dismounting work cannot be completed. Due to the ratchet 340 and the pawl 350, when the force application tool 500 is used to apply an external force, the force is not required to be applied continuously, so that the user is not tired.

The embodiment also provides an LED display screen system, which comprises the LED display screen mounting structure, the LED display screen 100 and a to-be-mounted part 200, wherein the LED display screen 100 and the to-be-mounted part 200 can be mounted and dismounted through the LED display screen mounting structure.

Second embodiment

This embodiment is an alternative embodiment of the first embodiment, and in this embodiment, the mounting structure only includes the first clip member 420, the second clip member 310 and the push rod 430. First joint piece 420 is direct and LED display screen 100 fixed connection, and it can't rotate for LED display screen 100, and first joint piece 420 has certain elasticity. However, in this case, when the push rod 430 is pushed, the difficulty of separating the protrusion 311 from the recess 421 is large, and the first engaging member 420 and the second engaging member 310 are easily damaged.

Third embodiment

This embodiment is an alternative to the first embodiment, in which case the ratchet 340 and pawl 350 need not be provided. However, in this case, the detaching process is unstable, and the push rod 430 may move reversely due to the resilience of the elastic member 440, so that the protrusion 311 is snapped into the recess 421 again, and the detaching process cannot be completed.

Fourth embodiment

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

Fifth embodiment

This embodiment is an alternative embodiment of the first embodiment, in which the first clamping member 420 is provided with a convex portion, and the second clamping member 310 is provided with a concave portion. Or, both a protruding portion and a recessed portion are arranged on the first clamping member 420, and both a recessed portion matched with the first clamping member 420 and a protruding portion matched with the first clamping member 420 are arranged on the second clamping member 310.

Sixth embodiment

This embodiment is an alternative embodiment of 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, and the distance between the rotation center and the first end of the push rod 430 is made larger than the distance between the rotation center and the second end of the push rod 430. Through the arrangement, the push rod can become a labor-saving lever, and the first clamping piece 420 and the second clamping piece 310 can be separated by applying a small force during 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 without departing from the spirit of the present invention within the knowledge of those skilled in the art. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
