Description

Technical Field

[0001] The invention belongs to the technical field of reflectors, and in particular relates to a reflector that is not easily worn. Background Art

[0002] Silicon carbide is particularly suitable for applications in space optical systems due to its low thermal deformation, high specific stiffness, dimensional stability and radiation resistance. Silicon carbide reflectors are optical reflectors made of silicon carbide. They have good mechanical and physical properties and are suitable for optical system reflectors in space satellites, lidar systems and space telescopes.

[0003] During the use of optical lenses, their edges are very easy to be bumped. Due to the low edge strength of optical lenses, the edges of the optical lenses are easily worn or even broken. Therefore, in the existing production, some optical lenses will be coated with a protective cover on the edge of the lens to improve its protection. For example, the optical reflector with application number CN202223084829.3 previously applied by the applicant is protected from wear by a protective cover, but the above technology still has defects. First of all, the protective cover in this technology is connected to it by a segmented cover clip. The segmented clipping is cumbersome to operate. At the same time, the surface of the reflector is not wear-resistant, which can easily cause the surface of the reflector to wear. Summary of the Invention

[0004] The purpose of the utility model is to provide a reflector that is not easy to wear, so as to solve the problem that the edges and the mirror surface of the current reflector are easy to wear during use.

[0005] The technical solution adopted by the utility model is as follows: a reflector that is not easy to wear, comprising a reflector body, wherein a limiting post is provided on the outer peripheral edge of the reflector body, and the outer peripheral edge of the reflector body is fixedly connected to the limiting post by a protective edging to prevent the outer peripheral edge of the reflector body from being worn;

[0006] A reinforcement layer is provided on the back of the reflector body, reinforcement ribs are provided inside the reinforcement layer, the reinforcement layer is sealed by a cover plate on the outer layer of the reinforcement layer, and a wear-resistant coating is provided on the front of the reflector body.

[0007] As a further improvement of the technical solution of the present invention, the limiting column and the reflector body are sintered as one piece, and the protective edging is made of wear-resistant rubber material.

[0008] As a further improvement to the technical solution of the present invention, the width of the protective edging does not exceed the thickness of the outer peripheral edge of the reflector body.

[0009] As a further improvement of the technical solution of the present invention, the reinforcing ribs are sintered integrally with the reflector body.

[0010] As a further improvement of the technical solution of the present invention, the cover plate and the reflector body are made of the same material and are glued and fixed to the reflector body.

[0011] As a further improvement of the technical solution of the present invention, the wear-resistant coating is a sol-gel coating.

[0012] The utility model has the following beneficial effects:

[0013] The optical reflector provided by the utility model has a protective edging that is an integrated elastic ring structure. When performing the edging operation, it only needs to be sleeved on the outer peripheral edge of the reflector body and matched with the limit column, which is easy to operate. At the same time, the surface of the reflector body is provided with a wear-resistant coating, which can effectively reduce the degree of wear on the mirror surface. Finally, the reflector body is provided with a reinforcement layer, which effectively improves the structural strength of the reflector and reduces the probability of deformation of the mirror surface.
