The position of the housing 10 corresponding to the opening of the elastic buckle 20 is provided with a through hole, so that the second half U-shaped arc portion 22 can be bent or folded outwards within the range of the through hole.
In some embodiments, the fourth end of the second half U-shaped arc 22 may not pass through the housing, so long as a person can bend the second half U-shaped arc 22 to release the second half U-shaped arc 22 from being engaged with the display module.
In some embodiments, the resilient catch 20 may be either horizontal or vertical.
In this embodiment, the rear cover of the LED display module is provided with a plurality of positioning posts 40 and countersunk screw holes 50, and the positions of the display module bracket 100 corresponding to the positioning posts 40 and countersunk screw holes 50 are respectively provided with positioning holes 70 and bracket screw holes 80.
It will be appreciated that cantilever snaps 32 may be provided in a plurality of evenly spaced apart locations, and cantilever snaps 30 may be provided adjacent the longer second side of the upper portion of the housing 10, or cantilever snaps 30 may be provided partially on the first side and partially adjacent the second side. The clip portion 33 may be extended downward or upward. Similarly, the elastic buckle 20 may be disposed near the second side of the upper portion of the housing 10, which is longer, or the elastic buckle 20 may be partially disposed near the first side and partially disposed near the second side.
Next, the installation process and the working principle of the rear cover of the LED display module are described:
firstly, a plurality of positioning columns 40 on the rear cover of the LED display module are in one-to-one correspondence with the positioning holes 70 on the display module bracket 100, and the positioning columns 40 are inserted into the positioning holes 70, and the positioning columns 40 and the positioning holes 70 are in one-to-one correspondence and have positioning functions, so that the rear cover of the LED display module can be combined with the display module bracket 100 in a preset mode through a plurality of positioning. When the rear cover of the LED display module is close to the display module bracket 100, the cantilever buckle 30 corresponds to the transverse plate 101, the second bump 222 on the elastic buckle 20 corresponds to the U-shaped engaging portion 60, and the countersunk screw hole 50 corresponds to the bracket screw hole 80.
Then, simultaneously, pressing forces are applied to different positions of the rear cover of the LED display module and the display module bracket 100, and finally, all the cantilever buckles 30 are in clamping connection with the transverse plate 101, and all the elastic buckles 20 are in clamping connection with the U-shaped clamping parts 60. The process of the cantilever buckle 30 clamping with the transverse plate 101 comprises the following steps: the clamping part 33 is abutted against the transverse plate 101 and is bent in a direction away from the transverse plate 101 under the action of the transverse plate 101, and the cantilever beam 32 passes through the transverse plate 101 under the action of pressure force, when the cantilever beam 32 just passes through the transverse plate 101, the clamping part 33 rebounds towards the transverse plate 101 and is clamped with the transverse plate 101. In the present embodiment, the length of the clip portion 33 extending in the direction perpendicular to the cantilever beam 32 is equal to or greater than the thickness of the cross plate 101. In this way, the cantilever snap 30 is made more difficult to separate from the cross plate 101. Under the effect of the pressing force, a second lug 222 in the elastic buckle 20 can be connected with the display module assembly in a clamping mode, the second half U-shaped arc portion 22 abuts against the flange 11, the second half U-shaped arc portion 22 can bend towards one side of the first half U-shaped arc portion 21, the shell is provided with an avoidance hole, the avoidance hole is used for avoiding an unlocking portion, the unlocking portion can move in the avoidance hole (that is to say, the second half U-shaped arc portion 22 can bend freely in the avoidance hole), a second limiting structure (flange 11) is arranged on one side of the avoidance hole, facing the second half U-shaped arc portion 22, of the second half U-shaped arc portion 22 can be folded outwards to be away from the first half U-shaped arc portion 21 until the second limiting structure (flange 11) abuts against the second half U-shaped arc portion 22. In this embodiment, the first half U-shaped arc portion 21 is hardly bent, and the second half U-shaped arc portion 22 is bent inwards or outwards by the external force. When the second half U-shaped arc 22 is bent inward to a predetermined angle, the first bump 221 will abut against the end surface of the first half U-shaped arc 21 facing the second half U-shaped arc 22, and the second half U-shaped arc 22 cannot be bent inward toward the first half U-shaped arc 21 by applying external force. Similarly, when the second half U-shaped arc portion 22 is folded outwards to a set angle, the second half U-shaped arc portion 22 will abut against the flange 11, and at this time, the second half U-shaped arc portion 22 cannot be folded outwards in a direction away from the first half U-shaped arc portion 21 again by applying external force. In this way, irreversible deformation of the elastic buckle 20 can be avoided, and the service lives of the elastic buckle 20 and the cantilever buckle 30 are greatly prolonged.
Finally, the screws pass through the countersunk screw holes 50 and the bracket screw holes 80 and are tightened, so that the rear cover can be kept stable by locking the countersunk screws when the elastic buckle 20 and the cantilever buckle 30 fail.
The concrete process of disassembling the rear cover of the LED display module is as follows:
the second half U-shaped arc part 22 is shifted by hand to be exposed out of the end part of the shell 10, and the second half U-shaped arc part 22 is bent towards the first arc end surface of the first half U-shaped arc part 21. Looking at fig. 4, the second half U-shaped arc 22 after bending is away from the flange 11. And after the second half U-shaped arc portion 22 is bent at a certain angle, the second bump 222 is completely separated from the U-shaped engaging portion 60, so as to release the engaging state between the second half U-shaped arc portion 22 and the display module. In some embodiments, the end of the second half U-shaped arc 22 may not be exposed to the housing 10, as long as the second half U-shaped arc 22 can be bent by a hand.
In other embodiments, a plurality of elongated bump-shaped reinforcing ribs are disposed in parallel on an end surface of the cantilever beam 32 on a side away from the clamping portion 33. In this way, the useful life of cantilever snap 30 may be increased.
In the present embodiment, the protruding portion (the U-shaped engaging portion 60) on the display module 100 is engaged with the second protruding portion 222 on the elastic buckle 20.
According to the rear shell of the LED display unit, the cantilever buckle 30 and the elastic buckle 20 are arranged on the joint surface of the shell 10 and are respectively positioned on two opposite sides of the joint surface, so that after the cantilever buckle 30 and the elastic buckle are respectively in clamping connection with the display module 100, the whole shell 10 is clamped on the display module 100; because the unlocking part of the elastic buckle 20 extends to the exposed surface of the shell 10, under the state that the shell 10 is clamped on the display module 100, an operator can touch the unlocking part, the elastic buckle 20 can be bent by stirring the unlocking part and can be in a clamping state with the display module 100, so that the shell 10 is detached from the display module 100, the whole clamping installation and detachment process is convenient, an operation tool is not needed, the operation difficulty is reduced, and the disassembly and assembly efficiency is high.
