A high-protection-level infrared athermalized lens

Abstract

This utility model discloses a high-protection-level infrared athermalized lens, belonging to the technical field of infrared athermalized lenses. It includes: a lens body; a first stop ring screwed to the front end of the lens body; a second stop ring screwed to the rear end of the lens body; and multiple elastic sheets arranged in a circular array along the axis of the lens body. The opposite ends of the elastic sheets are respectively engaged in the first and second stop rings, with adjacent elastic sheets fitting together. This utility model uses the first and second stop rings screwed onto the lens body as a support structure. The elastic sheets engaged between the two stop rings can distribute the impact force on the lens, and with the buffering effect of the two airbags, it has a buffering effect on external forces acting on the lens, thereby preventing the lens body from being deformed or damaged by direct impact, and improving the stability of the lens in use.

[0002] An infrared athermal lens is a specially designed optical system that can maintain stable image quality when the ambient temperature changes significantly, without the need for manual or automatic focusing.

[0003] Currently, lenses are prone to deformation or damage when subjected to direct impact, affecting their normal use. Utility Model Content

[0004] The purpose of this utility model is to provide a high-protection-level infrared athermalized lens in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-protection-level infrared non-thermal lens, comprising:

[0006] Lens body;

[0007] The first stop ring is screwed to the front end of the lens body;

[0008] The second stop ring is screwed to the rear end of the lens body;

[0009] Multiple elastic sheets are arranged in a circular array along the axis of the lens body. The opposite ends of the elastic sheets are respectively inserted into the first stop ring and the second stop ring. Adjacent elastic sheets are in contact with each other. A first air bladder is bonded to the inner wall of the elastic sheet and abuts against the surface of the lens body. A second air bladder is bonded to the outer wall of the elastic sheet.

[0010] As a further description of the above technical solution:

[0011] The axis of the first stop ring, the axis of the second stop ring, and the axis of the lens body coincide.

[0012] As a further description of the above technical solution:

[0013] Both the end of the first stop ring and the end of the second stop ring are provided with annular grooves, and the opposite ends of the elastic sheet are respectively inserted into the two annular grooves.

[0014] As a further description of the above technical solution:

[0015] The elastic sheet arches outward toward the lens body.

[0016] As a further description of the above technical solution:

[0017] The surfaces of the second airbag overlap.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] In this invention, the first and second stop rings screwed onto the lens body serve as a support structure. The elastic sheet snapped between the two stop rings can share the impact force on the lens. Furthermore, with the buffering effect of the two airbags, it has a buffering effect on the external force acting on the lens, thereby preventing the lens body from being deformed or damaged by direct impact and improving the stability of the lens in use.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a high-protection-level infrared pyrolysis lens, comprising:

[0029] Lens body 1;

[0030] The first stop ring 2 is screwed to the front end of the lens body 1;

[0031] The second stop ring 3 is screwed to the rear end of the lens body 1;

[0032] Multiple elastic sheets 4 are arranged in a circular array along the axis of the lens body 1. The opposite ends of the elastic sheets 4 are respectively inserted into the first stop ring 2 and the second stop ring 3. Adjacent elastic sheets 4 are attached to each other. A first airbag 5 is bonded to the inner wall of the elastic sheet 4. The first airbag 5 abuts against the surface of the lens body 1. A second airbag 6 is bonded to the outer wall of the elastic sheet 4.

[0033] The axis of the first stop ring 2, the axis of the second stop ring 3, and the axis of the lens body 1 coincide;

[0034] Both the end of the first stop ring 2 and the end of the second stop ring 3 are provided with annular grooves 7. The opposite ends of the elastic sheet 4 are respectively inserted into the two annular grooves 7, which facilitates the quick assembly of the elastic sheet 4.

[0035] The elastic sheet 4 arches outward toward the lens body 1, providing good elastic support and preventing the sheet from sticking to the surface of the lens body 1.

[0036] The surfaces of the second airbag 6 overlap to ensure the aesthetics of the structure.

[0037] Working principle: The first stop ring 2 and the second stop ring 3 screwed onto the lens body 1 serve as a support structure. The elastic piece 4, which is snapped between the first stop ring 2 and the second stop ring 3, can share the impact force on the lens. Furthermore, under the buffering effect of the first airbag 5 and the second airbag 6, it has a buffering effect on the external force acting on the lens, thereby preventing the lens body 1 from being deformed or damaged by direct impact, and improving the stability of the lens in use.
