Description

Technical Field

[0001] The utility model relates to the technical field of optical instruments, in particular to a reflective sheet that reflects light stably. Background Art

[0002] Generally, the visible light emitted by a light source is scattered in all directions. When the visible light emitted by the light source needs to be concentrated in one direction, a device with a reflective effect can be used to reflect the light propagating in other directions to the desired direction. A reflective sheet (reflector) has such a function.

[0003] In the prior art, conventional reflective sheets are mostly fixed to the installation position by fastening bolts, which makes subsequent disassembly and maintenance very inconvenient. Moreover, after installation, the level of the reflective sheet cannot be adjusted according to actual usage, resulting in the reflected light being offset and the reflected light being unstable. At the same time, the reflective sheet lacks protective function during use and is easily worn or contaminated. It also lacks anti-static function, which can easily cause damage to the entire module structure. Utility Model Content

[0004] The utility model provides a reflective sheet that reflects light stably, so as to solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a reflective sheet that reflects light stably, comprising a rectangular box, the upper surface of which is an open structure, a reflective sheet main body placed in the rectangular box, the upper surface cover of the reflective sheet main body being provided with a pressure frame, two sets of clamping mechanisms being provided on the four sides of the rectangular box, the lower surface of the rectangular box being fixedly connected to the main shaft of the universal ball head, a mounting plate being fixedly installed on the lower surface of the universal ball head, and an adjustment mechanism being provided on the middle part of the four sides of the upper surface of the mounting plate.

[0006] Furthermore, the reflective sheet main body includes a substrate layer, a base color layer, a metal reflective coating, a transparent adhesive, a transparent wear-resistant coating, a transparent oleophobic coating, an antistatic film and an insulating film. The upper surface of the substrate layer is sequentially pasted with the base color layer, the metal reflective coating, the transparent adhesive, the transparent wear-resistant coating and the transparent oleophobic coating from bottom to top, and the lower surface of the substrate layer is sequentially pasted with the antistatic film and the insulating film from top to bottom.

[0007] Furthermore, the upper surface of the pressing frame is flush with the upper surface of the rectangular box.

[0008] Furthermore, the clamping mechanism includes a damping sleeve, a pin and a pressure plate. The damping sleeve is fixedly installed on the side of the rectangular box. The movable buckle in the damping sleeve is installed with a pin. The upper surface of the pin is fixedly installed with a pressure plate. The lower surface of the pressure plate presses the upper surface of the pressure frame to limit it.

[0009] Furthermore, the adjustment mechanism includes a threaded sleeve, a bolt rod, a bearing assembly, a movable bevel block and a fixed bevel block. The threaded sleeve is fixedly mounted on the upper surface of the mounting plate, the bolt rod is mounted on the internal thread of the threaded sleeve, the movable bevel block is mounted on the end of the bolt rod through the bearing assembly, the fixed bevel block is fixedly mounted on the lower surface of the rectangular box corresponding to the upper surface of the movable bevel block, and the upper surface of the fixed bevel block is movably fitted with the lower surface of the movable bevel block.

[0010] Furthermore, the mounting plate is provided with a rectangular threaded hole for fixed installation.

[0011] Compared with the prior art, the present invention provides a reflective sheet that reflects light stably and has the following beneficial effects:

[0012] 1.

[0022] In this embodiment, the transparent glue 204, the transparent wear-resistant coating 205 and the transparent oleophobic coating 206 improve the wear resistance and oil-proof function of the upper surface of the reflector body 2, making it less susceptible to wear and damage, while keeping it clean and conducive to reflecting light. The antistatic film 207 and the insulating film 208 prevent the reflector body 2 from conducting electricity, avoiding damage to the light-emitting device and making it safer to use.

[0023] Specifically, the upper surface of the pressing frame 3 is flush with the upper surface of the rectangular box 1 .

[0024] In this embodiment, the pressing frame 3 is level with the rectangular box 1 and is not obtrusive, has a beautiful appearance, and is convenient for use.

[0025] Specifically, the clamping mechanism 4 includes a damping sleeve 401, a pin 402 and a pressure plate 403. The damping sleeve 401 is fixedly installed on the side of the rectangular box 1. The movable buckle in the damping sleeve 401 is installed with the pin 402. The upper surface of the pin 402 is fixedly installed with a pressure plate 403. The lower surface of the pressure plate 403 presses the upper surface of the pressure frame 3 to limit it.

[0026] In this embodiment, the pin shaft 402 rotates in the damping sleeve 401 , so that the pressing plate 403 is spun onto the upper surface of the pressing frame 3 , thereby achieving the effect of installing and fixing the reflective sheet body 2 .

[0027] Specifically, the adjustment mechanism 7 includes a threaded sleeve 701, a bolt rod 702, a bearing assembly 703, a movable bevel 704 and a fixed bevel 705. The threaded sleeve 701 is fixedly mounted on the upper surface of the mounting plate 6. The bolt rod 702 is installed on the internal thread of the threaded sleeve 701. The movable bevel 704 is installed on the end of the bolt rod 702 through the bearing assembly 703.

[0029] Specifically, the mounting plate 6 is fixedly provided with a rectangular threaded hole 8 .

[0030] In this embodiment, the threaded holes 8 are used to fasten bolts to fix the mounting plate 6 .

[0031] When in use, the reflective sheet body 2 is placed in the rectangular box 1, and the pin shaft 402 in the pressing mechanism 4 rotates in the damping sleeve 401, so that the pressing plate 403 is spun on the upper surface of the pressing frame 3, thereby achieving the effect of installing and fixing the reflective sheet body 2, facilitating the disassembly and assembly of the reflective sheet body 2, and facilitating the later maintenance and replacement of the reflective sheet body 2. The transparent glue 204, the transparent wear-resistant coating 205 and the transparent oleophobic coating 206 in the reflective sheet body 2 improve the wear resistance and oil-proof function of the upper surface of the reflective sheet body 2, making it not easily damaged by wear and at the same time keeping it clean, which is conducive to reflecting light. The antistatic film 207 and the insulating film 206 are provided on the reflective sheet body 2. The film 208 prevents the reflector body 2 from being conductive, thus avoiding damage to the light-emitting device and making it safer to use. The mounting plate 6 is installed at the mounting location with the fastening bolts through the threaded holes 8, thereby achieving the effect of installing the reflector body 2. After installation, the bolt rod 702 in the surrounding adjustment mechanism 7 moves left and right in the threaded sleeve 701, so that the bolt rod 702 drives the movable bevel block 704 to move left and right through the bearing assembly 703. The movable bevel block 704 and the fixed bevel block 705 are at different positions, so that the rectangular box 1 can be tilted and rotated along the universal ball head 5 to ensure a better light reflection angle and more stable light reflection.

[0032] To sum up, the reflective sheet that reflects light stably is convenient for disassembly and assembly of the reflective sheet main body 2, and is convenient for later maintenance and replacement. At the same time, after installation, the level of the reflective sheet main body 2 can be adjusted to ensure that it remains level, making the light reflection more stable, improving the wear resistance and anti-fouling performance of the reflective sheet main body 2, adding anti-static function, and making it safer to use.
