Description

Technical Field

[0001] This utility model relates to the field of light guide plate technology, and in particular to a light guide plate that is easy to install. Background Technology

[0002] A light guide plate is a high-tech product made of optical-grade acrylic or PC sheets. Its design principle is mainly derived from the LCD screen technology of laptops. The light guide plate guides and disperses light by printing light guide points on the bottom surface of the sheet using laser engraving, V-shaped cross grid engraving, or UV screen printing technology.

[0003] The existing technology, Chinese Patent Publication No. CN211293333U, discloses a light guide plate that is easy to install. It includes a mounting base, with the light guide plate body movably connected to the bottom of the mounting base. A mounting top bracket is mounted on the upper surface of the mounting base, and the inner side of the lower surface of the mounting top bracket is tightly fitted to the outer side of the upper surface of the light guide plate body. Multiple screws are detachably connected to the upper surface of the mounting top bracket. The light guide plate body is detachably connected to the mounting base and the mounting top bracket via these screws. After connection, the mounting base and mounting top bracket clamp the light guide plate body between them, thus achieving the effect of convenient installation of the light guide plate body. Furthermore, it eliminates the need for drilling holes in the upper part of the light guide plate body during installation, reducing pressure damage to the light guide plate body caused by drilling, which would reduce the lifespan of the light guide plate body. The installation is simple and convenient, improving the efficiency of installing the light guide plate body.

[0004] In practice, the top frame is fixed with screws, and the top frame is used in conjunction with the bottom frame to fix the light guide plate. However, the screw fixing method cannot quickly disassemble or assemble the light guide plate, resulting in a longer disassembly or installation time and poor practicality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to quickly assemble and disassemble light guide plates, and to propose a light guide plate that is easy to install.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an easy-to-install light guide plate, including a bracket and a light guide plate body inside it. The bracket includes a support frame and a back plate for closing the opening on the back of the support frame. The back plate and the support frame are fixed together by a quick-release assembly.

[0008] The back plate side is provided with a reset component between it and the light guide plate body. The reset component is used to reset the back plate. A positioning component for positioning the light guide plate body is also provided inside the support frame.

[0009] Furthermore, the quick-release assembly includes a docking post and a connecting post. The front of the support frame is provided with a through groove, and the docking post is fixedly connected to the inner side of the through groove at the corner. The connecting post is fixedly connected to the inner side of the back plate, and the connecting post is correspondingly arranged with the docking post.

[0010] Furthermore, at least one of the free ends of the connecting post is recessed towards the axis to form a connecting portion. The top of the connecting portion is fixedly connected to a first tapered portion and slidably connected to a second tapered portion. The first tapered portion and the second tapered portion have the same structure and are arranged opposite to each other. The diameter of the first tapered portion matches that of the connecting post.

[0011] Furthermore, grooves are provided on both sides of the inner wall of the docking column. A pair of grooves have locking parts that slide relative to each other through springs. The bottom of the pair of locking parts on opposite sides is provided with guide slopes, and they abut and slide against the conical surfaces of the first conical part and the second conical part through the guide slopes. The top of the locking part also abuts against the bottom of the second conical part.

[0012] Furthermore, the reset component includes a compression spring, and a support plate is fixedly connected to the inner side of the back plate via the compression spring. The support plate is used to abut against the light guide plate body, so that the light guide plate body fits against the inner side of the support frame.

[0013] Furthermore, the inner side of the support frame is fixedly connected to the positioning member next to the connecting column. The positioning member has an L-shaped structure, and the openings between them are arranged in corresponding directions to form an installation space. The main body of the light guide plate is located in the installation space and abuts against the positioning member.

[0014] The present invention provides an easy-to-install light guide plate with the following advantages: The back plate is fixed by means of a snap-fit ​​mechanism that slides against the conical surfaces of the first and second conical portions. Because the snap-fit ​​mechanism slides against the pair of conical portions, the back plate can be quickly disassembled by pressing, and the light guide plate can be disassembled by unlocking the back plate. This facilitates installation and reduces disassembly time. Furthermore, a positioning component is provided inside the support frame. The positioning component, together with the reset component, provides space for the back plate to move and supports the light guide plate. The structure is simple and highly practical.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A light guide plate that is easy to install includes a bracket 1 and a light guide plate body 2 inside it. The bracket 1 includes a support frame 11 and a back plate 12 for closing the opening on the back of the support frame 11. The back plate 12 is fixed to the support frame 11 by a quick-release assembly 3.

[0022] Among them, a reset member 4 is provided between the side of the back plate 12 and the light guide plate body 2. The reset member 4 is used to reset the back plate 12. A positioning member 5 is also provided inside the support frame 11 for positioning the light guide plate body 2.

[0023] It should be added that in the existing technology, optical films and reflectors are respectively set on the light-emitting surface and the backlight surface of the light guide plate body 2. Of course, light-emitting components such as light strips are also required inside the bracket 1 to provide light source for the light guide plate body 2.

[0024] Furthermore, the quick-release assembly 3 includes a docking post 31 and a connecting post 32. The front of the support frame 11 is provided with a through groove 13, and the docking post 31 is fixedly connected to the inner side of the through groove 13 at the corner. The connecting post 32 is fixedly connected to the inner side of the back plate 12, and the connecting post 32 is correspondingly arranged with the docking post 31.

[0025] It should be noted that the through groove 13 is used to avoid the light-emitting surface of the light guide plate body 2, and the opening size of the through groove 13 is smaller than that of the light guide plate body 2, so as to stop the light guide plate body 2.

[0026] Furthermore, at least one of the free ends of the connecting post 32 is recessed towards the axis to form a connecting portion 321. The top of the connecting portion 321 is fixedly connected to a first tapered portion 33 and slidably connected to a second tapered portion 34. The first tapered portion 33 and the second tapered portion 34 have the same structure and are arranged opposite to each other. The diameter of the first tapered portion 33 matches that of the connecting post 32.

[0027] like Figure 4 As shown, the top diameter of the first tapered portion 33 gradually decreases, and the bottom diameter of the second tapered portion 34 gradually decreases. The diameter of the pair of tapered portions matches that of the connecting post 32, so that they can be inserted into the through hole at the free end of the docking post 31.

[0028] More specifically, the inner walls of the docking post 31 are provided with sliding grooves on both sides. Inside the pair of sliding grooves, there are locking parts 36 that slide relative to each other via springs 35. The bottom of the pair of locking parts 36 on opposite sides is provided with guide slopes, and they abut and slide against the conical surfaces of the first conical part 33 and the second conical part 34 via the guide slopes. The top of the locking part 36 also abuts against the bottom of the second conical part 34.

[0029] It is worth mentioning that the opposite ends of the pair of snap-fit ​​parts 36 have shaft ends, and they are slidably connected to the mating post 31 through the shaft ends. The spring 35 is sleeved on the periphery of the shaft ends, and the two ends of the spring 35 abut against the snap-fit ​​part 36 and the inner wall of the slide groove, respectively.

[0030] In specific operation, the snap-fit ​​parts 36 on both sides are located between the first conical part 33 and the second conical part 34 and abut against the bottom of the first conical part 33. They then work with the compression spring 41 to achieve a fixing effect, thereby fixing the back plate 12 to the support frame 11.

[0031] Then, the back plate 12 is pushed so that the locking part 36 avoids the second conical part 34 using the guide slope. Under the push of the compression spring 41, the back plate 12 drives the locking part 36 to move in the opposite direction. The locking part 36 abuts against and slides against the conical surface of the second conical part 34. When the second conical part 34 is in contact with the first conical part 33, the locking part 36 disengages from the connecting post 32 to unlock.

[0032] In general, the reset member 4 includes a compression spring 41, and a support plate 42 is fixedly connected to the inner side of the back plate 12 through the compression spring 41. The support plate 42 is used to abut against the light guide plate body 2, so that the light guide plate body 2 is in contact with the inner side of the support frame 11.

[0033] Finally, the inner side of the support frame 11 is fixedly connected to the positioning member 5 next to the connecting column 32. The positioning member 5 has an L-shaped structure, and the openings between them are arranged in corresponding directions to form an installation space. The light guide plate body 2 is located in the installation space and abuts against the positioning member 5.

[0034] Working method: During operation, the light guide plate body 2 is positioned and placed by the positioning parts 5 on both sides. When the back plate 12 is closed, the docking post 31 and the connecting post 32 engage. At the same time, a pair of engaging parts 36 abut against and slide against the first conical part 33 through the guide slope and the spring 35. At this time, the compression spring 41 uses the support plate 42 to press against the light guide plate body 2. The compression spring 41 compresses and applies pressure to drive the back plate 12 to move in the opposite direction. However, the engaging parts 36 and the first conical part 33 stop and fix the back plate 12.

[0035] When it is necessary to unlock the back plate 12, press the back plate 12 again. The compression spring 41 allows the back plate 12 to move through the movement space. When the back plate 12 moves, a pair of locking parts 36 use the guide slope and spring 35 to abut and slide against the second conical part 34. Under the push of the compression spring 41, the back plate 12 drives the locking parts 36 to move. When the second conical part 34 is in contact with the first conical part 33, the locking parts 36 use the conical surface to disengage from the connecting post 32, and the back plate 12 can be unlocked and the light guide plate body 2 can be disassembled.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
