[0002] Background of the Invention When photographing a mirror-reflective object (eg, glass, mirror, etc.), special attention should be paid to how to control and manage the cleanliness of the mirror surface to ensure that the photo is not disturbed by stains, reflections or other undesirable factors.

[0003] During the wiping and cleaning process of the existing zoom lens, dust is easily wiped off to the junction between the lens and the housing, resulting in incomplete cleaning of the lens and affecting the shooting effect. Utility Model Content

[0004] The utility model aims to solve the problem that dust is easily wiped off the junction between the lens and the shell during the wiping and cleaning process of the existing zoom lens, resulting in incomplete lens cleaning, and proposes a medium-wave cooling infrared continuous zoom lens.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a medium-wave cooled infrared continuous zoom lens, comprising a shell, a top cover, a perforated partition and a lens edge dust scraping mechanism, the shell is a hollow cylinder, and the shell is installed on the lens body, the perforated partition is installed in the shell, the top cover is installed at one end of the shell, and the lens edge dust scraping mechanism is clamped on the perforated partition.

[0006] As a further description of the above technical solution:

[0007] The lens edge scraping mechanism includes a scraping needle, a rotating column, two extension rods and two elastic ropes. The rotating column passes through the perforated partition plate, the scraping needle and the two extension rods are installed at both ends of the rotating column, and the two elastic ropes are installed at the other ends of the two extension rods and connected to the inner wall of the shell.

[0008] As a further description of the above technical solution:

[0009] An adjusting spring is installed at one end of the rotating column close to the top cover, and the other end of the rotating column is made of microfiber material.

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

[0011] The length of the extension rod is greater than the length of the elastic rope.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] In the utility model, the lens body is designed with a lens edge scraping mechanism, which rotates and scrapes away dust on the edge of the lens, so that the junction between the lens and the shell is kept clean, which not only helps to improve the quality of photos, but also can extend the service life of the camera lens.

[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] See also Figure 1-4 The utility model provides a technical solution: a medium-wave refrigerated infrared continuous zoom lens, comprising a shell 1, a top cover 2, a perforated partition 3 and a lens edge dust scraping mechanism 4, wherein the shell 1 is a hollow cylinder, and the shell 1 is mounted on a lens body 6, the perforated partition 3 is mounted in the shell 1, the top cover 2 is mounted at one end of the shell 1, and the lens edge dust scraping mechanism 4 is clamped on the perforated partition 3;

[0022] The lens edge scraping mechanism 4 includes a scraping needle 41, a rotating column 42, two extension rods 43 and two elastic ropes 44. The rotating column 42 passes through the perforated partition 3. The scraping needle 41 and the two extension rods 43 are installed at both ends of the rotating column 42. The two elastic ropes 44 are installed at the other ends of the two extension rods 43 and are connected to the inner wall of the shell 1. It is easy to operate, the simple structure is more stable, and the maintenance or replacement cost of a small number of parts is low.

[0023] An adjustment spring 5 is installed at one end of the rotating column 42 close to the top cover 2, and the other end of the rotating column 42 is made of microfiber material to prevent the rotating column 42 from wearing the mirror surface;

[0024] The length of the extension rod 43 is greater than the length of the elastic rope 44, so that the scraper needle 41 encounters dust resistance when rotating to avoid violent cleaning.

[0025] Working principle: First, the shell 1 is installed on the lens body 6, the shell 1 is aligned with the mirror surface, and the shell 1 is rotated so that the scraping needle 41 in the lens edge scraping mechanism 4 scrapes off the dust at the junction of the mirror surface and the shell. Secondly, if it rotates clockwise, the scraping needle 41 has a small scraping force on the dust at the junction of the mirror surface and the shell. Finally, if it rotates counterclockwise, the scraping needle 41 has a large scraping force on the dust, which enriches the user's choice. The elastic deformation of the elastic rope 44 provides resistance to the scraping needle, thereby increasing the cleanliness of the mirror surface.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
