The first clamping jaw 22 is used for being matched with the first clamping jaw hole 11 of the display screen backboard 1 in a clamping mode, and the second clamping jaw 23 is used for being matched with the second clamping jaw hole 12 of the display screen backboard 1 in a clamping mode.

Fig. 5 is a perspective view of the mounting bracket 2 according to the embodiment of the present invention. Fig. 6 is a rear view of the mounting bracket 2 according to an embodiment of the present invention. Fig. 7 is a cross-sectional view of section X-X in fig. 6.

Referring to fig. 5, the main body 21 includes a bottom wall 211 and a side wall 212 disposed on the periphery of the bottom wall 211. The side wall 212 protrudes rearward relative to the bottom wall 211, and the bottom wall 211 and the side wall 212 enclose a semi-closed space. Wherein, the bottom wall 211 is provided with a partition 213 which divides the semi-closed space into a cavity 214 and a wire arrangement groove 215 which are adjacent.

In the present embodiment, the partition 213 extends in the up-down direction, and the wire management groove 215 is located on the left side of the cavity 214 with reference to the view direction of fig. 5.

First, the structure of the cavity 214 portion is described.

In conjunction with fig. 6 and 7, the cavity 214 is provided with an opening corresponding to the sidewall 212 above the display device 100. The first latch 22 is suspended from the opening, that is, the first latch 22 extends from the bottom wall 211, specifically, extends to the front of the display device 100 and then extends upward.

The first jaw 22 is of a resilient arm construction. Specifically, the first claws 22 include elastic portions 221 extending forward from the bottom wall 211 and fixing portions 222 extending upward from the elastic portions 221.

The elastic portion 221 elastically snaps into the first claw hole 11, and the size of the first claw hole 11 changes according to the size of the first claw 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 engaged with the display screen backboard 1. A gap of 0.1mm may be left between the fixing portion 222 and the matching surface of the display screen backplane 1, so as to avoid that no margin is left between the matching surfaces, which may cause the engagement to require brute force and generate fragments.

In this embodiment, the bottom wall 211 is provided with grooves corresponding to the two sides of the first jaw 22, so that the rigidity of the first jaw 22 is reduced, and the elasticity is increased.

Referring to fig. 5 to 7, the second latch 23 extends away from the cavity 214 and is inserted into the second latch hole 12, that is, the second latch 23 extends toward the front of the display device 100 and is inserted into the second latch hole 12. The size of the second jaw hole 12 varies according to the size of the second jaw 23.

The second catch 23 is likewise of resilient arm construction. Specifically, the second pawl 23 includes a connecting portion 231 protruding forward from the main body 21 and an engaging portion 232 located at a tip end of the connecting portion 231.

The clamping part 232 is clamped with the display screen backboard 1, and the end face of the clamping part 232 is provided with an inclined plane. The inclined surface has a guiding function, so that the second jaw 23 can conveniently extend into the second jaw hole 12. The fitting surface of block portion 232 and display screen backplate 1 and the plane that display screen backplate 1 is located have little contained angle between, specifically can be 3 to 5 degrees, can leave 0.1 mm's clearance simultaneously between the fitting surface of block portion 232 and display screen backplate 1, avoids not having the surplus between the fitting surface equally, leads to the block to need to use brute force, produces the piece.

Referring to fig. 7, the direction in which the second latch 23 is engaged with the second latch hole 12 is opposite to the direction in which the first latch 22 is engaged with the first latch hole 11, that is, the direction in which the second latch 23 is engaged corresponds to the lower portion of the display device 100.

After the first claws 22 are caught in the first claw holes 11 when the mounting bracket 2 is mounted on the display screen back plate 1, deformation is provided by pressing the elastic portions 221 of the first claws 22 so that the first claws 22 recover elastic deformation when the second claws 23 are inserted into the second claw holes 12. Because the first claw 22 has elasticity, the mounting bracket 2 does not need to be clamped into the display screen backboard 1 firmly, and the generation of debris is avoided.

When the installation is completed, the first claw 22 and the second claw 23 stably install the installation bracket 2 on the display screen backboard 1 due to the direction in which the second claw 23 is engaged with the second claw hole 12 is opposite to the direction in which the first claw 22 is engaged with the first claw hole 11, and the elastic force of the first claw 22.

When the mounting bracket 2 is removed, the second claws 23 are pulled out from the second claw holes 12 without a brute force by pressing the elastic portions 221 of the first claws 22 to deform.

Therefore, adopt the utility model discloses a double cassette claw structure has solved the problem that clamps the difficulty, falls the bits, and easy installation is just dismantled, has improved the installation effectiveness. Meanwhile, the mounting bracket 2 is not easy to damage by brute force, and the reuse rate of the mounting bracket 2 is improved.

Referring to fig. 2, the external antenna 4 is fixed in the wire-arranging groove 215, one end of the external antenna is connected with the wireless board 3, and the other end of the external antenna extends out of the opening.

Adopt the utility model discloses a fixed antenna 4 that draws outward of reason wire casing 215 can guide and draw outward antenna 4 around the upper end to display device 100, when satisfying customer's demand, optimizes the reason line in the display device 100 and prevents that external force from drawing outward antenna 4 by mistake to do not need tape-stripping, improved and produced line efficiency.

Referring to fig. 6 and 7, the partition 213 divides the main body 21 into a cavity 214 and a wire arrangement groove 215, and the wire arrangement groove 215 extends in the vertical direction. The lower half of the partition plate 213 is recessed forward, i.e., the width of the upper half of the partition plate 213 in the front-rear direction is larger than the width of the lower half thereof in the front-rear direction, with a smooth transition in the middle. The width of the recessed portion of the partition 213 in the front-rear direction is substantially equal to the height of the rib 216.

The end of the concave part of the partition 213 is provided with a supporting plate 217, the supporting plate 217 is perpendicular to the partition 213, and the supporting plate 217 is located at the lower end of the wire arranging groove 215. The mounting bracket 2 also includes a stop post 26. The retaining post 26 is raised from the support plate 217. One end of the external antenna 4 close to the wireless board 3 is wound on the blocking column 26.

At this time, a part of the pulling force of the pull-out antenna 4 is consumed by the pin 26, preventing an external force from pulling the pull-out antenna 4 by mistake, and further guiding the pull-out antenna 4 to wind toward the upper end of the display device 100. Meanwhile, with reference to fig. 2, the supporting plate 217 makes the root of the retaining pillar 26 and the wireless board 3 on the same plane, and after the external antenna 4 is connected to the wireless board 3, the supporting plate can be well supported when winding around the retaining pillar 26, so as to facilitate subsequent fixing in the wire arrangement groove 215.
