[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes in detail, with reference to the accompanying drawings, a backlight guide plate and lamp strip alignment and calibration fixture according to an embodiment of the present invention.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of the backlight light guide plate and lamp strip alignment calibration fixture provided by this utility model includes a frame 1, a limiting plate 2 fixedly installed inside the frame 1, a baffle 6 slidably connected inside the frame 1, and a pressing mechanism provided on the inner wall of the frame 1.

[0027] The holding mechanism includes a rotating shaft 4, a pressure plate 5, a mounting shaft 13, and a support pad 15. The rotating shaft 4 is rotatably connected inside the frame 1 and is located on one side of the limiting plate 2. The pressure plate 5 is fixedly installed on the side wall of the rotating shaft 4. A mounting groove 12 is opened on one side of the pressure plate 5. The mounting shaft 13 is fixedly installed inside the mounting groove 12. The support pad 15 is rotatably connected to the side wall of the mounting shaft 13. A second spring 11 is fixedly installed at the bottom of the limiting plate 2. A holding member 3 is fixedly installed at the bottom of the second spring 11. A handle 7 is fixedly installed on one side of the baffle 6.

[0028] It should be noted that the limiting plate 2 can be used to restrict the installation position of the light strip, so that the light strip can be installed on the backlight guide plate side by simply placing it into the gap between one side of the limiting plate 2 and the inner wall of the frame 1. The rotating shaft 4 can be used to control the rotation of the pressure plate 5. The rotation of the pressure plate 5 can be used to press the light strip downward, so that the light strip is not easy to shift while waiting for the glue to solidify, resulting in a better assembly effect. The second spring 11 can be used to support the holding member 3, so that the holding member 3 can press the surface of the backlight guide plate inside the frame 1, preventing the backlight guide plate from moving inside the frame 1.

[0029] In some embodiments, such as Figure 3As shown, the end face of the support pad 15 is semi-circular, and several support pads 15 are provided. A third spring 14 is fixedly installed on the inner wall of the mounting groove 12, and the other end of the third spring 14 is fixedly installed on one side of the support pad 15.

[0030] It should be noted that by setting the third spring 14, the support pad 15 can be used to support the support pad 15, so that the support pad 15 can fit more closely to the surface of the light strip after contacting the light strip, providing a more stable downward pressure effect for the light strip.

[0031] In some embodiments, such as Figure 4 As shown, a movable cavity 16 is provided on one side of the frame 1. A nut 18 is slidably connected inside the movable cavity 16. One end of the rotating shaft 4 is located inside the movable cavity 16. The nut 18 is movably connected to the side wall of one end of the rotating shaft 4. A fourth spring 17 is fixedly installed on the inner wall of the movable cavity 16. The other end of the fourth spring 17 is in contact with the nut 18.

[0032] It should be noted that one end of the rotating shaft 4 has a thread that fits into the nut 18. When the rotating shaft 4 is rotated by setting the nut 18, the nut 18 engages with the thread on the side wall of the rotating shaft 4 and slides in the movable cavity 16. The fourth spring 17 can be used to support the nut 18, so that the rotating shaft 4 is not easy to rotate on its own. The other end of the rotating shaft 4 has anti-slip texture, which makes it easy to control the rotation of the rotating shaft 4.

[0033] Example 2

[0034] In some embodiments, such as Figure 2 As shown, the inner wall of the frame 1 has an installation cavity 8, and a first spring 9 is fixedly installed on the inner wall of the installation cavity 8. A clamping member 10 is fixedly installed on the other end of the first spring 9. The clamping member 10 is an arc-shaped member.

[0035] It should be noted that the first spring 9 can be used to support the clamping member 10, so that the clamping member 10 can limit the backlight light guide plate inserted into the frame 1, and prevent the backlight light guide plate from shifting left and right in the frame 1. The clamping member 10 is an arc-shaped part. During the insertion of the backlight plate, the clamping member 10 will be pushed into the mounting cavity 8. The clamping member 10 is supported by the first spring 9 to clamp the backlight plate. Both the clamping member 10 and the pressing member 3 are made of silicone to avoid scratching the backlight plate.

[0036] Working principle: During use, the baffle 6 is pulled out from the frame 1 by the handle 7. Then, the backlight light guide plate is inserted into the frame 1 through the sliding groove of the baffle 6. The clamping part 10 can limit the backlight light guide plate inserted into the frame 1 to prevent the backlight light guide plate from shifting left and right in the frame 1. The pressing part 3 can press the surface of the backlight light guide plate inside the frame 1 to prevent the backlight light guide plate from moving inside the frame 1. Then, the lamp body with glue is placed into the gap between one side of the limiting plate 2 and the inner wall of the frame 1, so that the lamp strip is located on one side of the backlight light guide plate surface. Then, the pressure plate 5 is rotated by rotating the shaft 4. The rotation of the pressure plate 5 can be used to press the lamp strip downward to prevent the lamp strip from shifting while waiting for the glue to solidify, thus completing the installation of the lamp strip and the backlight light guide plate.

[0037] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
