[0021] 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.

[0022] The following is combined with Figure 1-5 This application is described in further detail.

[0023] A spacer for a lens barrel comprises a barrel 3, a lens 4 and a main body 2 of the spacer, wherein the lens 4 is arranged in the barrel 3, the main body 2 is arranged in the barrel 3, the main body 2 is pressed against the lens 4, and the movement of the lens 4 is restricted by the main body 2. A fixing groove 8 is provided on the outer wall of the main body 2, and a rubber ring 7 adapted to the fixing groove 8 is fixedly provided on the inner wall of the barrel 3, and the rubber ring 7 is clamped in the fixing groove 8.

[0024] The cross section of the fixing groove 8 is semicircular. The rubber is elastic and easily deforms elastically when subjected to force. The shape of the fixing groove 8 facilitates the rubber ring 7 to be clamped in the fixing groove 8. There is a certain gap between the outer wall of the main body 2 and the inner wall of the lens barrel 3, which facilitates the removal of the main body 2. The inner wall of the main body 2 is provided with an annular groove 1. When the main body 2 is removed, the annular groove 1 facilitates the removal of the main body 2 from the lens barrel 3.

[0025] The inner wall of the lens barrel 3 is provided with a mounting groove 9, in which a spring 6 is fixedly arranged, one end of the spring 6 is fixedly connected to a fixing block 5, and a limiting groove 10 is provided on the side of the rubber ring 7 close to the mounting groove 9, the limiting groove 10 is communicated with the mounting groove 9, and the fixing block 5 abuts against the limiting groove 10.

[0026] The end of the fixing block 5 facing the limiting groove 10 is semicircular in shape, and the shape of the fixing groove 8 matches the fixing block 5. When the rubber ring 7 is clamped in the fixing groove 8, the spring 6 is extended, and one end of the fixing block 5 is against the limiting groove 10, so that the installation stability of the main body 2 in the lens barrel 3 is better.

[0027] When disassembling the main body 2, the main body 2 is pulled upward through the annular groove 1, the rubber ring 7 is deformed by the force, the rubber ring 7 squeezes the fixing block 5, the fixing block 5 is squeezed into the installation groove 9, the spring 6 is compressed, and as the main body 2 is continuously pulled upward, the rubber ring 7 is separated from the fixing groove 8, and the main body 2 is removed from the lens barrel 3.

[0028] The implementation principle of this embodiment is as follows: when installing the lens 4 and the spacer on the lens barrel 3, the lens 4 is placed in the lens barrel 3, and then the main body 2 is placed in the lens barrel 3, and the main body 2 is pressed downward, the rubber ring 7 is deformed by force, the fixing block 5 is squeezed, the spring 6 is compressed, and the fixing block 5 is located in the installation groove 9, and then the main body 2 is pressed downward, the rubber ring 7 is clamped in the fixing groove 8, and the main body 2 is pressed against the lens 4. At this time, the spring 6 is extended, the fixing block 5 is pressed against the limiting groove 10, and the rubber ring 7 is pressed against the fixing groove 8. The main body 2 is not easy to fall off from the lens barrel 3 under the action of the rubber ring 7 and the fixing block 5, so that the spacer is not easy to fall off from the lens barrel 3.
