[0002] Lenses can be widely used in various fields such as security, automotive, digital cameras, lasers, and optical instruments. With the continuous development of the market, lens technology is becoming more and more widely used. Optical lenses can not only improve the uniformity of LED light source illumination, but also expand the illumination range of LED lights. Existing optical lenses are generally directly bonded to the backlight panel, and the optical lens is installed using an external threaded pressure ring method.

[0003] However, after the optical lens is installed using an external threaded retainer, the external threaded retainer cannot press the optical lens tightly because one side of the optical lens has an uneven structure. Even after the external threaded retainer is tightened, the optical lens will still wobble due to looseness, affecting the uniformity of the light source illumination. Utility Model Content

A second screw hole 6 is provided at the top of the inner cavity of the groove 5. A threaded rod 7 is inserted into the inner cavity of the second screw hole 6. A first screw hole 4 is provided on the side wall of the protrusion 3. The threaded rod 7 is matched with the first screw hole 4 and the second screw hole 6 respectively. A circular plate 8 is fixedly connected to the bottom of the threaded rod 7. A first limiting post 9 is fixedly connected to the bottom of the circular plate 8. The circular plate 8 is movably inserted into the inner cavity of the groove 5. The bottom of the circular plate 8 is flush with the bottom of the protrusion 3. A transverse groove 10 is provided at the bottom of the first limiting post 9.

[0032] A rotating shaft 12 is rotatably connected to the connecting seat 11. A frame 13 is fixedly connected to the end of the rotating shaft 12 away from the connecting seat 11. A connecting rod 14 is movably threaded through the frame 13. A top plate 21 and a bottom plate 20 are fixedly connected to both ends of the connecting rod 14, respectively. A spring 15 is sleeved on the outer edge of the connecting rod 14. The top end of the spring 15 is fixedly connected to the frame 13, and the bottom end of the spring 15 is fixedly connected to the bottom plate 20. A second limiting post 16 is fixedly connected to the bottom of the bottom plate 20. The bottom of 6 is set at a height lower than the bottom of the first limiting post 9. The top plate 21 and the top of the connecting rod 14 are both provided with insertion holes 17. The inner cavity of the insertion hole 17 is movably connected to the first fixing rod 18. The frame 13 is provided with a second fixing rod 19 on one side. The cross-section of the first fixing rod 18 and the second fixing rod 19 is L-shaped. The first fixing rod 18 and the second fixing rod 19 are both fixedly connected to the outer wall of the fixing collar 1. The insertion hole 17 is matched with the first fixing rod 18 and the second fixing rod 19 respectively.

[0033] Working principle: This utility model is a silicone backlight lens. When the device needs to be transferred and carried, the fingernail is used to rotate the first limiting post 9 in conjunction with the horizontal groove 10. The first limiting post 9 drives the circular plate 8 and the threaded rod 7 to rotate. The threaded rod 7 rotates in the inner cavity of the second threaded hole 6. Under the action of the thread, the threaded rod 7 moves away from the second threaded hole 6. Then the threaded rod 7 is moved and tightened in the inner cavity of the first threaded hole 4, fixing the first limiting post 9 on the side wall of the protrusion 3.

[0034] Then, pull down the second limiting post 16. The second limiting post 16 drives the connecting rod 14 to move downward through the base plate 20. At the same time, the spring 15 is stretched, and the connecting rod 14 drives the top plate 21 to move downward. The top plate 21 moves downward until it is in contact with the top of the frame 13. At this time, the top plate 21 is away from the first fixing rod 18. Then, maintain the tension of the second limiting post 16, and flip the frame 13, connecting rod 14, top plate 21 and base plate 20 through the second limiting post 16. Flip the top plate 21 to correspond with the second fixing rod 19. At this time, the second limiting post 16 is set horizontally. Then, slowly release the tension on the second limiting post 16. The top plate 21 moves towards the second fixing rod 19 under the elastic action of the spring 15. The top plate 21 is sleeved on the outside of the second fixing rod 19 through the insertion hole 17, thereby fixing the second limiting post 16 in a horizontal state.

[0035] The device fixes the first limiting post 9 to the side wall of the protrusion 3 by tightening the threaded rod 7 into the inner cavity of the first threaded hole 4. In addition, the second limiting post 16 is pulled down and rotated to a horizontal position. At the same time, the second limiting post 16 is fixed by the second fixing rod 19. At this time, the first limiting post 9 and the second limiting post 16 no longer protrude from the bottom of the fixing collar 1, which greatly reduces the overall volume and makes it convenient to transfer and carry.

[0036] When installing the first limiting post 9, use your fingernail to rotate the first limiting post 9 in conjunction with the horizontal groove 10. This will cause the threaded rod 7 to rotate. Unscrew the threaded rod 7 from the side wall of the protrusion 3 and tighten it into the inner cavity of the second threaded hole 6. When installing the first limiting post 9, pull the second limiting post 16 and rotate it to a vertical position. At this time, the top plate 21 corresponds to the first fixing rod 18. Then release the tension on the second limiting post 16 and fix the second limiting post 16 in a vertical position through the first fixing rod 18.

[0037] When installing the silicone lens 2, place the silicone lens 2 inside the external threaded pressure ring and install it through the external threaded pressure ring. Rotate the external threaded pressure ring to install it. As the external threaded pressure ring moves the silicone lens 2 backward, the first limiting post 9 and the second limiting post 16 effectively limit the silicone lens 2. Then, under the reaction force of the spring 15, the silicone lens 2 is effectively pressed against the inside of the external threaded pressure ring. At the same time, the first limiting post 9 and the second limiting post 16 in the first limiting assembly are embedded in the backlight screen to ensure that the silicone lens 2 will not shake after installation.
