Description

Technical Field

[0001] This utility model relates to the field of light-emitting backplate technology, and in particular to an adjustable-angle light-emitting backplate fixing device. Background Technology

[0002] Illuminated backplates are a new type of material that combines LED light sources with light guide materials. They have unique lighting and decorative effects and are widely used in home and commercial fields. Illuminated backplates install LED light sources inside or on the edge of the backplate and utilize the optical properties of the light guide plate to transform point or line light sources into surface light sources, thereby achieving a uniform light emission effect.

[0003] Currently, illuminated backlights are widely used in advertising displays, interior decoration, and product display scenarios. The performance of their fixing devices directly affects the effect of use. Most of the luminous backlight fixing devices on the market are designed with a fixed angle, which cannot flexibly adjust the tilt angle of the backlight according to display needs, lighting conditions, or viewing angle, resulting in poor applicability. To address this issue, we propose an adjustable-angle luminous backlight fixing device. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-angle light-emitting backplate fixing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable-angle light-emitting backplate fixing device includes a support block, a rotating mechanism connected to the upper surface of the support block, a moving block connected to the outer surface of the rotating mechanism, a connecting plate connected to the upper surface of the moving block, two sets of through holes on the upper surface of the connecting plate, a positioning mechanism connected to the right side of the support block, and a mounting plate connected to the bottom surface of the support block, with two sets of circular holes on the upper surface of the mounting plate.

[0007] In a further embodiment, the rotating mechanism includes a connecting frame connected to the support block, the inner sidewall of the connecting frame being inlaid with two rolling bearings, the inner rings of the two rolling bearings being connected to a connecting rod connected to the moving block, and the right end of the connecting rod being connected to a gear.

[0008] In a further embodiment, the positioning mechanism includes a fixed plate connected to a support block, a slide cylinder embedded in the upper surface of the fixed plate, a positioning rod slidably connected to the inner wall of the slide cylinder, a push plate connected to the bottom end of the positioning rod, a tension spring connected to the upper surface of the push plate, and the top end of the tension spring connected to the bottom surface of the fixed plate.

[0009] In a further embodiment, a display panel is provided above the mounting plate, and the back of the display panel is connected to the front of the support block.

[0010] In a further embodiment, reinforcing blocks are connected to both the left and right sides of the moving block, and the upper surface of each reinforcing block is connected to the bottom surface of the connecting plate.

[0011] In a further embodiment, a pull ring is provided on the right side of the support block, and the outer surface of the pull ring is connected to the bottom surface of the push plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, through the cooperation of rolling bearings and connecting rods in the rotating mechanism, combined with the limiting and unlocking functions of the positioning mechanism, can realize the angle adjustment of the light-emitting back panel around the axis of the connecting rod. It can adapt to the lighting requirements or display viewing angle requirements in different scenarios, effectively improving the applicability of the device. Utilizing the tension provided by the tension spring in the positioning mechanism, it is easy for the push plate to be pulled by the tension to push the positioning rod to slide inside the slide cylinder. At the same time, it is also conducive to the positioning rod contacting the gear to limit the gear's operation, thereby locking the adjustment angle. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this utility model, an adjustable angle light-emitting backplate fixing device includes a support block 7, a rotating mechanism 1 connected to the upper surface of the support block 7, a moving block 9 connected to the outer surface of the rotating mechanism 1, a connecting plate 8 connected to the upper surface of the moving block 9, two sets of through holes 11 opened on the upper surface of the connecting plate 8, a positioning mechanism 2 connected to the right side of the support block 7, and an mounting plate 4 connected to the bottom surface of the support block 7, two sets of round holes 5 opened on the upper surface of the mounting plate 4.

[0023] The rotating mechanism 1 includes a connecting frame 101 connected to the support block 7. Two rolling bearings 102 are embedded in the inner wall of the connecting frame 101. The inner rings of the two rolling bearings 102 are connected to a connecting rod 103 connected to the moving block 9. A gear 104 is connected to the right end of the connecting rod 103. The design of the rolling bearings 102 and the connecting rod 103 facilitates the movement of the moving block 9. The positioning mechanism 2 includes a fixed plate 201 connected to the support block 7. A slide cylinder 204 is embedded in the upper surface of the fixed plate 201. A positioning rod 205 is slidably connected to the inner wall of the slide cylinder 204. A push plate 203 is connected to the bottom end of the positioning rod 205. A tension spring 202 is connected to the upper surface of the push plate 203. The top end of the tension spring 202 is connected to the bottom surface of the fixed plate 201. The design of the tension spring 202 and the push plate 203 facilitates the positioning rod 205 to limit the gear 104.

[0024] A display panel 6 is provided above the mounting plate 4. The back of the display panel 6 is connected to the front of the support block 7. The display panel 6 facilitates the demonstration of the operation process of the device. Reinforcing blocks 10 are connected to both sides of the moving block 9. The upper surface of each reinforcing block 10 is connected to the bottom surface of the connecting plate 8. The design of the reinforcing blocks 10 facilitates the increase of the stability of the connecting plate 8. A pull ring 3 is provided on the right side of the support block 7. The outer surface of the pull ring 3 is connected to the bottom surface of the push plate 203. The design of the pull ring 3 facilitates the movement of the push plate 203.

[0025] The working principle of this utility model is as follows:

[0026] In use, the device is first installed in the position of use by the design of the mounting plate 4 and the round hole 5. Then, the light-emitting back plate is installed on the connecting plate 8 by the through hole 11. When adjusting, pull the pull ring 3 downward. The pull ring 3 drives the push plate 203 to move downward in sync. The push plate 203 drives the tension spring 202 to extend. At this time, the positioning rod 205 slides downward along the inner wall of the slide cylinder 204, so that the top of the positioning rod 205 disengages from the meshing state with the gear 104 and releases the limit on the gear 104.

[0027] Then, the backlight plate is pushed, which drives the moving block 9 to rotate through the connecting plate 8. The moving block 9 is connected to the connecting rod 103 of the rotating mechanism 1. The connecting rod 103 rotates synchronously in the inner rings of the two rolling bearings 102 embedded in the inner wall of the connecting frame 101, realizing the angle adjustment of the backlight plate around the axis of the connecting rod 103. When the backlight plate is adjusted to the target angle, the pull ring 3 is released, the tension spring 202 pulls the push plate 203 to reset upward. The push plate 203 drives the positioning rod 205 to slide upward along the inner wall of the slide cylinder 204, so that the top of the positioning rod 205 re-meets the tooth groove of the gear 104, restricting the rotation of the gear 104. Then, the angle of the backlight plate is fixed through the connecting rod 103, the moving block 9 and the connecting plate 8, completing the entire angle adjustment and fixing process.
