[0002] A lens is an optical component, usually made of a transparent material such as glass or plastic, that has one or two curved surfaces and changes the direction of light passing through it.

[0003] Traditionally, the lens of a lamp is usually installed by screw fixing. Although the stability is good, the installation process is cumbersome and requires the use of tools. It cannot be installed without tools, which is inconvenient and needs to be improved. Utility Model Content

[0009] By adopting the above technical solution, when the base and the lens body are installed together, the elastic plate, the connecting plate and the connecting rod are snapped into the snap-in area, the elastic plate is compressed to produce elastic deformation, and the end of the elastic plate away from the connecting plate is bent toward the connecting rod. The end of the elastic plate away from the connecting plate has a force to bend in the direction away from the connecting rod, so that the elastic plate and the connecting rod are respectively pressed against the inner walls of the lens body facing each other, thereby realizing the installation between the base and the lens body.

The limiting block and the inner wall of the clamping area form an installation groove for cooperating with the connecting rod, and the limiting block is located between the two elastic plates.

[0015] By adopting the above technical solution, when the connecting rod is inserted into the installation groove, the opposite sides of the two elastic plates are in contact with the limit blocks, and the limit blocks and the inner walls of the clamping area limit the horizontal movement of the clamping part on the base, thereby improving the stability of the clamping part installed on the base or the lens body.

[0016] Optionally, the two elastic plates are respectively inclined toward one side of the connecting plate and in opposite directions, and the facing inner walls of the clamping area are both provided with limit blocks, and the two limit blocks are located between the two elastic plates.

[0017] By adopting the above technical solution, when two elastic plates with opposite inclination directions are installed in the clamping area, the two elastic plates are compressed to produce elastic deformation, so that the ends of the two elastic plates away from the connecting plate are bent in the direction of approaching each other, and the ends of the two elastic plates away from the connecting plate have a force to bend in the direction of moving away from each other, so that the two elastic plates are respectively abutted against the inner walls facing each other in the clamping area, thereby realizing the installation between the base and the lens body.

The positioning block limits the horizontal movement of the clamping part, thereby improving the stability of the clamping part installed on the base or the lens body.

[0020] Optionally, the clamping area is arranged in a ring shape.

[0021] By adopting the above technical solution, multiple clamping parts can be installed at different positions of the clamping area, which indirectly increases the contact area between the base and the lens body, increases the friction force, and improves the installation stability between the base and the lens body.

[0022] Optionally, the base or the lens body is provided with a fixing groove for cooperating with the elastic plate, and the fixing groove is communicated with the clamping area.

[0023] By adopting the above technical solution, the elastic plate is inserted into the fixing groove, the outer surface of the elastic plate fits with the inner wall of the fixing groove, and the inner wall of the fixing groove restricts the movement of the clamping part, thereby improving the stability of the clamping part installed on the base or the lens body.

[0024] Optionally, the base is provided with a receiving cavity for cooperating with the lens body.

[0025] By adopting the above technical solution, the lens body is inserted into the accommodating cavity, and the outer surface of the lens body fits with the inner wall of the accommodating cavity.
