[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] according to Figure 1-5 As shown: The utility model provides a display screen lighting image inspection jig: it includes an inspection table 1, on which a display screen main body 3 is placed; a left light shield 2 and a right light shield 4 that are engaged with each other are slidably arranged on the inspection table 1, and the display screen main body 3 is located inside the left light shield 2 and the right light shield 4; a motor 12 that can control the sliding of the left light shield 2 and the right light shield 4 is arranged on one side of the inspection table 1; support columns 15 are fixedly arranged on the inner walls of the left light shield 2 and the right light shield 4, and sliding plates 17 are fixedly arranged on the ends of the support columns 15; a support seat 19 is arranged at the lower end of the display screen main body 3, and clamping blocks 18 are arranged on both sides of the support seat 19; a fixing rod 21 is fixedly arranged on the clamping block 18, and the sliding plate 17 is slidably sleeved on the fixing rod 21.

[0021] By using the motor 12 and providing two mutually engaging left and right shading covers 2 and 4, the shading cover can be installed quickly. While installing the shading cover, the clamping block 18 can also be used to fix the display screen body 3, which is very convenient.

[0022] A bidirectional screw 13 is rotatably provided in the inspection table 1 and is fixedly connected to the output shaft of the motor 12. Two oppositely arranged moving blocks 14 are threadedly connected to the bidirectional screw 13. A guide groove 5 is provided on the upper surface of the inspection table. Two connecting rods 11 are fixedly connected to the moving blocks 14 in the guide groove 5. The two connecting rods 11 are fixedly connected to the left light shield 2 and the right light shield 4, respectively.

[0023] The setting of the bidirectional screw rod 13 can make the left light shield 2 and the right light shield 4 move towards or away from each other at the same time, thereby improving the installation efficiency of the light shield. The cooperation between the connecting rod 11 and the guide groove 5 can limit the rotation of the moving block 14, thereby converting the rotation of the bidirectional screw rod 13 into the movement of the moving block 14, and transmitting the movement to the left light shield 2 and the right light shield 4 through the connecting rod 11.

[0024] A spring 20 sleeved on a fixed rod 21 is provided between the sliding plate 17 and the clamping block 18, and a stopper 16 fixedly connected to the fixed rod 21 is provided on one side of the sliding plate 17. The spring 20 can generate a rebound force on the clamping block 18 when compressed, thereby playing the role of clamping the support seat 19 of the display screen body 3. The setting of the stopper 16 can prevent the sliding plate 17 from detaching from the fixed rod 21.

[0025] A positioning groove 10 corresponding to the shape of the support seat 19 is provided on the inspection table 1 , and the support seat 19 is located in the positioning groove 10 . The arrangement of the positioning groove 10 facilitates the rapid positioning of the display screen body 3 .

[0026] A connecting groove 8 is provided in the left light shield 2, and a connecting block 9 inserted into the connecting groove 8 is fixedly connected to the right light shield 4; a wire outlet hole 7 is provided on the rear side of the left light shield 2 and the right light shield 4, and an inspection groove 6 is provided on the front side of the left light shield 2 and the right light shield 4.

[0027] The plug-in arrangement of the connection block 9 and the connection slot 8 can reduce the light transmittance of the gap at the connection between the left light shield 2 and the right light shield 4. The arrangement of the outlet hole 7 facilitates the power cord of the display screen body 3 to be normally connected to the power supply, and the staff can inspect the display screen of the display screen body 3 through the inspection slot 6.

[0028] Principle of the utility model

[0029] When checking the lighting image of the display screen, the support seat 19 under the display screen body 3 is placed in the positioning groove 10 for positioning; the motor 12 is started, and the left light shield 2 and the right light shield 4 move towards each other under the drive of the moving block 14. When the left light shield 2 and the right light shield 4 move towards each other, first, the two clamping blocks 18 contact the support seat 19. Due to the limitation of the support seat 19, the clamping blocks 18 can no longer move. As the left light shield 2 and the right light shield 4 continue to approach each other, the sliding plate 17 slides on the fixed rod 21, compressing the spring 20, and the spring 20 generates a rebound force on the clamping block 18, thereby playing the role of clamping the support seat 19 and fixing the display screen body 3. As the left light shield 2 and the right light shield 4 get closer, the connecting block 9 is inserted into the connecting groove 8, and the two are combined to form a complete light shield, and the display screen body 3 is powered on. Check whether the entire screen is evenly illuminated from the inspection groove 6, and check whether there are abnormal conditions such as dark spots and bright spots. In summary, the present application utilizes the motor 12 and provides two mutually engaging left and right light shields 2 and 4, which can quickly complete the installation of the light shield, and can also complete the fixation of the display screen body 3 while installing the light shield, which is very convenient.

[0030] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
