[0010] In one embodiment, bottom connecting support legs are provided at the four corners of the bottom of the inspection device body, and the bottom connecting support legs are installed and connected to the inspection device body by threads.

[0011] In one embodiment, a movable limiting groove is provided on both sides of the inspection device body, and a built-in connecting spring is provided in the movable limiting groove.

[0012] In one embodiment, a telescopic connecting post is provided at the end of the built-in connecting spring body, and a side snap-fit ​​plate is connected to the end of the telescopic connecting post. The side snap-fit ​​plate and the telescopic connecting post are an integral structure.

[0013] In one embodiment, a plug-in locking limit post is provided near the upper side of the side locking plate, and a second movable limiting groove is provided on the outer side of the plug-in locking limit post and located on the LED lamp pressure plate.

[0014] Beneficial effects: 1. In the light guide plate illumination inspection device, adsorption rubber sheets are installed near the four corners of the inspection placement slot. An internal ventilation connecting pipe is installed at the end of each adsorption rubber sheet, and a telescopic connector is installed at the end of the internal ventilation connecting pipe. An internal limiting movement chamber is installed on the outer side of the telescopic connector. A central connecting threaded post is connected to the side of the telescopic connector, and an adjustment knob is located at the outer middle of the central connecting threaded post. The central connecting threaded post and the adjustment knob are connected by threads. Because there is no restriction when placing the light guide plate in the inspection placement slot, the light guide plate may shake due to contact, affecting the user's observation. In this improved device, after the light guide plate is placed in the inspection placement slot, the user rotates the adjustment knob, which drives the central connecting threaded post to move and stretch the telescopic connector. The increased extension space of the telescopic connector creates a negative pressure at the adsorption rubber sheet, thus adsorbing the light guide plate into the inspection placement slot for stable placement. This improves the stability of the light guide plate placement and effectively enhances the practicality of the light guide plate illumination inspection device.

[0015] 2. In the light guide plate illumination inspection device, movable limiting grooves are provided on both sides of the inspection device body. An internal connecting spring is installed in the movable limiting groove, and a telescopic connecting post is installed at the end of the internal connecting spring. A side snap-fit ​​plate is connected to the end of the telescopic connecting post. The side snap-fit ​​plate and the telescopic connecting post are an integral structure. A plug-in snap-fit ​​limiting post is provided near the upper side of the side snap-fit ​​plate. A movable limiting groove is provided on the outside of the plug-in snap-fit ​​limiting post and located on the LED lamp pressure plate. The LED lamp pressure plate is usually installed and connected to the inspection device body using screws. This makes installation and disassembly relatively troublesome when replacing LED lamps, which is not conducive to improving the work efficiency of the staff. This improved device allows the LED lamp pressure plate to be squeezed and installed after the LED lamp is installed. Then, the internal connecting spring stretches the side snap-fit ​​plate, causing the plug-in snap-fit ​​limiting post to snap into the movable limiting groove two to restrict the LED lamp pressure plate. This effectively improves the installation and disassembly efficiency of the LED lamp pressure plate, thereby effectively improving the practicality of the light guide plate illumination inspection device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] To achieve the above-mentioned utility model objectives, such as Figure 1-4 As shown, this utility model provides a light guide plate lighting inspection device, including: an inspection device body 1 and a detection placement groove 2 provided on the inspection device body 1; Adsorption rubber sheets 5 are installed near the four corners of the detection placement slot 2. An internal ventilation connecting pipe 12 is installed at the end of each adsorption rubber sheet 5. A telescopic connector 8 is installed at the end of each internal ventilation connecting pipe 12. An internal limiting movement chamber 11 is installed on the outer side of the telescopic connector 8. A central connecting threaded post 9 is connected to the side of the telescopic connector 8. A toggle adjustment knob 10 is located on the outer middle of the central connecting threaded post 9. The central connecting threaded post 9 and the toggle adjustment knob 10 are connected by threads. Because the detection placement slot 2 is used for placing light guides... Without restrictions on the placement of the light guide plate, it can wobble due to contact or other reasons, affecting the user's observation. In this improved version, after the light guide plate is placed in the detection placement slot 2, the user can rotate the adjustment knob 10 to move the telescopic connector 8 via the threaded drive of the central connecting threaded post 9. The increased extension space of the telescopic connector 8 creates a negative pressure at the position of the adsorption rubber sheet 5, thereby adsorbing the light guide plate into the detection placement slot 2 for stable placement. This improves the stability of the light guide plate placement and effectively enhances the practicality of the light guide plate lighting inspection device.

[0021] like Figure 1 As shown, a plug-in connection hole 7 is connected to the left side of the inspection device body 1. A conductor is provided in the plug-in connection hole 7, which is used to plug in an external connection wire for power supply.

[0022] like Figure 1 As shown, an LED light pressure plate 3 is connected to the upper part of the inspection device body 1 near the front. An LED light is installed at the bottom of the LED light pressure plate 3. An adjustment control button 4 is installed on the right side of the inspection device body 1. The adjustment control button 4 controls the on and off of the LED light. The LED light pressure plate 3 can squeeze and restrict the LED light for protection. The LED light can illuminate the light guide plate in the inspection placement slot 2, and then the user can observe the patterns, stains, etc. on the light guide plate.

[0023] like Figure 1As shown, bottom connecting support legs 6 are provided at the four corners of the bottom of the inspection device body 1. The bottom connecting support legs 6 are connected to the inspection device body 1 by threads. The bottom side of the bottom connecting support legs 6 is made of rubber. The rubber structure of the bottom connecting support legs 6 can increase the friction with the placement surface, thereby improving the placement stability of the inspection device body 1 and preventing the inspection device body 1 from sliding.

[0024] like Figure 4 As shown, the inspection device body 1 has movable limiting grooves 13 on both sides, with an internal connecting spring 14 inside each groove. A telescopic connecting post 15 is located at the end of the internal connecting spring 14, and a side snap-fit ​​plate 16 is connected to the end of the telescopic connecting post 15. The side snap-fit ​​plate 16 and the telescopic connecting post 15 are integrally formed. A snap-fit ​​limiting post 17 is located near the upper side of the side snap-fit ​​plate 16. A movable limiting groove 18 is located outside the snap-fit ​​limiting post 17 and on the LED lamp pressure plate 3. Plate 3 is usually installed and connected to the inspection device body 1 using screws. Its installation and disassembly are relatively troublesome when replacing LED lights, which is not conducive to improving the work efficiency of the staff. After the LED light is installed, the LED light pressure plate 3 can be squeezed and installed. Then, the side snap-fit ​​plate 16 is stretched by the built-in connecting spring body 14 so that the plug-in snap-fit ​​limit post 17 is snapped into the moving limit groove 18 to restrict the LED light pressure plate 3. This can effectively improve the installation and disassembly efficiency of LED light pressure plate 3, and thus effectively improve the practicality of the light guide plate lighting inspection device.
