Description

Technical Field

[0001] The utility model relates to the technical field of light guide plates, in particular to an adjustable light guide plate. Background Art

[0002] The light guide plate is made of optical-grade acrylic and PC sheets, and then uses high-tech materials with extremely high refractive index and no light absorption. The light guide points are printed on the bottom of the optical-grade acrylic sheet by laser engraving, V-shaped cross grid engraving, and UV screen printing technology. The optical-grade acrylic sheet is used to absorb the light emitted from the lamp and stay on the surface of the optical-grade acrylic sheet. When the light hits each light guide point, the reflected light will spread to various angles, and then destroy the reflection conditions and be emitted from the front of the light guide plate. Through various light guide points of different densities and sizes, the light guide plate can emit light evenly.

[0003] Existing decorative light guide plates are usually composed of an outer mounting frame and a matching light guide plate. For example, a decorative lamp disclosed in Chinese patent announcement number "CN208719877U" includes a light-emitting part and a light guide plate with a pattern fixed above the light source of the light-emitting part. The light guide plate is composed of a plurality of sub-light guide plates, and the positions of the sub-light guide plates can be interchanged to form different patterns.

[0004] This type of light guide plate is fixedly installed when in use. After the light guide plate is installed, the angle of the light guide plate cannot be adjusted, resulting in a reduced scope of application. In addition, since the light guide plate needs to be installed using screws, the current installation holes of the light guide plate cannot be adjusted, and the holes are easily misaligned during installation. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An adjustable light guide plate is designed, comprising a support seat, a lamp holder and a light guide plate, wherein mounting plates are fixed on both sides of the top of the support seat, the light guide plate is arranged on the top of the lamp holder, the lamp holder is rotatably connected between the two mounting plates and an adjustment disk is fixed on one side of the lamp holder, a plurality of annular teeth are provided on the surface of the adjustment disk, a clamping mechanism is provided between the support seat and the adjustment disk, a sliding groove is penetrated through the surface of the lamp holder, two mounting mechanisms are slidably connected to the inner side of the sliding groove, and mounting holes are penetrated through both sides of the surface of the light guide plate.

[0008] Furthermore, the clamping mechanism includes a vertical plate, which is fixed to one side of the top of the support seat, and one side of the vertical plate is connected to a sliding sleeve, and the interior of the sliding sleeve is slidably connected to a sliding column, and a chuck is fixed to the inner side of the sliding column, and the chuck is engaged with an annular tooth on the surface of the adjusting disk, and a spring is provided on the surface of the sliding column, and the two sides of the spring are respectively in contact with the chuck and the vertical plate.

[0009] Furthermore, guide bars are fixed on both upper and lower sides of the sliding column, and the guide bars are slidably connected to the sliding sleeve.

[0010] Furthermore, a circular plate is fixed on the outer side of the sliding column, and a pull ring is fixed on the outer side of the circular plate.

[0011] Furthermore, the mounting mechanism includes a movable plate, which is slidably connected to the slide groove, a through groove is provided on the surface of the movable plate, at least two clamping grooves are provided on the inner side of the through groove, a mounting block is slidably connected between at least two of the clamping grooves, and a threaded hole is provided on the surface of the mounting block.

[0012] Furthermore, the diameter of the threaded hole is the same as the diameter of the mounting hole, and the threaded hole is located at the center of the mounting block.

[0013] The utility model proposes an adjustable light guide plate, which has the beneficial effects that: the utility model can flexibly adjust the inclination angle of the light guide plate by clamping the chuck and the adjustment disk, and can conveniently adjust the light guide plate for display, while the spring and the matching sliding column can clamp the light guide plate for convenient fixation, and the mounting threaded hole can be flexibly adjusted, so that the light guide plate can be fixed and installed more conveniently, which can solve the shortcomings in the prior art that the angle of the light guide plate cannot be adjusted after the installation is completed, and the mounting hole position of the light guide plate cannot be adjusted.
