[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] A pressing ring structure for a lens comprises a lens barrel 1, a main body of the pressing ring and a lens 2. The main body is arranged in the lens barrel 1, the main body presses against the lens 2, the lens 2 is below the main body, a mounting frame is arranged on the lens barrel 1, the lens 2 is placed on the mounting frame, the lens 2 is between the mounting frame and the main body, and the main body plays a role in positioning and fixing the lens 2.

[0023] The main body includes an upper ring 4 and a lower ring 9. The outer wall of the upper ring 4 is provided with a thread. The upper ring 4 is threadedly connected to the lens barrel 1. The lower ring 9 is pressed against the lens 2. The upper ring 4 is connected to the lower ring 9. A plug-in groove 7 is provided on the side of the upper ring 4 close to the lower ring 9. A plug-in ring 8 matched with the plug-in groove 7 is fixedly provided on the side of the lower ring 9 close to the upper ring 4. The plug-in ring 8 and the lower ring 9 are integrally formed, and the plug-in ring 8 is plugged into the plug-in groove 7.

[0024] A limit plate 11 is fixedly arranged on one side of the plug slot 7 close to the lower ring 9. Two limit plates 11 are arranged on the plug slot 7. The two limit plates 11 are arranged on both sides of the plug slot 7 respectively. The plug ring 8 is between the two limit plates 11. The limit plates 11 play a role of limiting stability. The plug ring 8 can move up and down in the plug slot 7. The limit plates 11 can ensure the movement stability of the plug ring 8 in the plug slot 7, so that the plug ring 8 is not easy to shake when moving.

[0025] A fixing groove 3 is clamped on one side of the upper ring 4 away from the lower ring 9, and a plurality of fixing grooves 3 are provided on the upper ring 4. A first threaded hole is provided in the fixing groove 3, and the first threaded hole is communicated with the plug-in groove 7. A second threaded hole 10 is provided on the plug-in ring 8, and the first threaded hole is communicated with the second threaded hole 10. A threaded rod 6 is threadedly connected to the first threaded hole, and the threaded rod 6 is threadedly connected to the second threaded hole 10.

[0026] The plug-in ring 8 is a T-shaped structure, and the structure of the plug-in ring 8 makes it difficult for the plug-in ring 8 to fall off from the plug-in groove 7. A buffer layer is fixedly provided on the side of the upper ring 4 close to the lower ring 9. When the upper ring 4 is pressed against the lower ring 9, the buffer layer presses against the lower ring 9, and the buffer layer plays a buffering role. A tightening ring 5 is fixedly provided on the side of the lower ring 9 close to the lens 2, and the tightening ring 5 presses against the lens 2, and the tightening ring 5 plays a role in better stabilizing and fixing the lens 2.

[0027] The implementation principle of this embodiment is: when installing the pressure ring, the lens 2 is first placed in the lens barrel 1, and then the upper ring 4 of the main body is threadedly connected in the lens barrel 1, the lower ring 9 and the tightening ring 5 press against the lens 2, the lens 2 is fixed between the lens barrel 1 and the lower ring 9, and then the threaded rod 6 is tightened. In the process of tightening the threaded rod 6, the plug-in ring 8 moves in the direction away from the plug-in groove 7, and the lower ring 9 presses against the lens 2 more tightly with the movement of the plug-in ring 8, and the lens 2 is fixed more firmly, so that the positioning effect of the main body on the lens 2 is better, thereby achieving the effect of improving the positioning effect of the pressure ring on the lens 2.
