The main body 21 is provided with a cavity 213 for accommodating the wireless module 3, the latch 22 is used for being in clamping fit with the latch hole 11 of the display screen backboard 1, and the first buckle 23 is used for being in clamping fit with the buckle hole 12 of the display screen backboard 1.

Fig. 4 is a perspective view of the mounting bracket 2 according to the embodiment of the present invention. Fig. 5 is a rear view of the mounting bracket 2 according to an embodiment of the present invention. Fig. 6 is a cross-sectional view of section X-X in fig. 5.

Referring to fig. 4, the main body 21 includes a bottom wall 211 having a substantially flat plate shape and a side wall 212 disposed on a peripheral side of the bottom wall 211. The side wall 212 projects rearwardly relative to the bottom wall 211, the bottom wall 211 and the side wall 212 enclosing a cavity 213. Reinforcing ribs 214 are provided in the cavity 213 to increase the strength of the mounting bracket 2.

In the present embodiment, the cavity 213 is defined by a bottom wall 211 and three side walls 212, and the three side walls 212 respectively correspond to the side walls 212 below and on the left and right sides of the display device 100, and the cavity 213 has an opening with respect to the top of the display device 100.

Referring to fig. 5 and 6, the latch 22 is suspended outward from the opening of the cavity 213, that is, the latch 22 extends forward of the display device 100 and then extends upward.

The jaw 22 is of cantilevered construction. Specifically, the claw 22 includes an elastic portion 221 extending forward from the main body 21 and a fixing portion 222 extending upward from the elastic portion 221.

The elastic portion 221 elastically snaps into the jaw hole 11, and the size of the jaw hole 11 varies according to the size of the jaw 22. The elastic portion 221 extends forward such that the fixing portion 222 extends beyond the bottom wall 211 of the main body 21.

The fixing portion 222 is matched with the display screen backboard 1, and the distance between the plane where the fixing portion 222 is matched with the display screen backboard 1 and the outer surface of the bottom wall 211 is equal to the thickness of the display screen backboard 1.

In the present embodiment, the claws 22 extend upward from the ribs 214 and then extend forward, and the length of the elastic portion 221 is increased, so that the rigidity of the claws 22 is reduced and the elasticity is increased.

The number of jack catchs 22 can be a plurality of, and a plurality of jack catchs 22 have not identical width dimension, and the purpose is for preventing slow-witted, lets the user need not expend energy, also need not experience and professional knowledge, just can be fixed in installing support 2 on display screen backplate 1.

In this embodiment, the two claws 22 are suspended side by side from the opening of the cavity 213, and the width dimensions of the two claws 22 are different.

Referring to fig. 4 to fig. 6, the first latch 23 extends out away from the cavity 213 and is inserted into the latch hole 12, that is, the first latch 23 extends out to the front of the display device 100, and the size of the latch hole 12 is changed according to the size of the first latch 23.

The direction of engagement of the first catch 23 with the catch hole 12 is opposite to the direction in which the claw 22 extends outward, i.e., the direction in which the first catch 23 engages corresponds to the lower side of the display device 100. After the click 22 is clicked into the click hole 11, the first click 23 can be inserted into the click hole 12 by elastically deforming the click 22 by pressing. After the first catch 23 is inserted into the catch hole 12, the claw 22 is restored to elastic deformation. At this time, the latch 22 and the first latch 23 stably mount the mounting bracket 2 on the display back panel 1 due to the engagement of the first latch 23 with the latch hole 12 in a direction opposite to the direction in which the latch 22 extends outward, and the elastic force of the latch 22.

The first catch 23 is also of cantilevered construction. Specifically, the first catch 23 includes a connecting portion 231 extending forward from the main body 21 and an engaging portion 232 located at a distal end of the connecting portion 231.
