Description

Technical Field

[0001] This utility model relates to the field of front lens barrel technology, specifically a front lens barrel with an anti-deformation structure. Background Technology

[0002] A lens barrel, also known as a lens tube, is a specially made metal or plastic cylinder used to fix the lens elements of a lens. The length of the lens barrel varies depending on the focal length of the lens, and its diameter matches the lens aperture. The front end of the lens barrel has a screw thread for mounting a lens hood, and the rear end of the lens barrel has a screw thread (or bayonet) for mounting a camera. A current patent, patent publication number CN203422515U, describes a lens barrel that does not use metal parts and includes electronic circuits and electronic components that are protected from static electricity. In this lens barrel, the lens barrel (1) has a circuit board (5) built into its internal space R, which is connected to the outside through a gap (d1). On the circuit board (5), a grounding pattern (52c) is provided at a position facing the gap (d1). The grounding pattern (52c) is formed on the outer side of the electronic circuit section of the circuit board. The static electricity applied to the electronic circuit section from the gap (d1) is applied to the grounding pattern (52c) near the gap (d1) and absorbed. Therefore, it is not applied to the electronic circuit section, thereby preventing malfunction and electrostatic damage in the electronic circuit section.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: although they can be connected using threaded bayonets, the lack of an effective support structure makes the lens barrel easily deformed when subjected to external impacts, which can lead to compression damage to the lenses installed inside. Therefore, we propose a front lens barrel with an anti-deformation structure to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a front lens barrel with an anti-deformation structure, which solves the problem that existing lens barrels are prone to deformation when subjected to external impacts due to the lack of an effective support structure, which can lead to compression damage to the lenses installed inside.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a front lens barrel with an anti-deformation structure, including a base, the main body of which is an annular structure, and an annular groove is provided at the top of the base. The annular groove is a mounting groove, and a metal sheet is fixedly connected inside the mounting groove. A reinforcing rib of an annular structure is fixedly connected inside the groove provided at the top of the base. A sealing ring is fixedly connected to the inner wall of the base. The sealing ring is made of rubber, and there are two sealing rings. The two sealing rings are fixedly connected to the inner wall of the base in a linear array.

[0006] Preferably, a connecting plate is fixedly connected to the inner wall of the base. There are six connecting plates in total, and the six connecting plates are fixedly connected to the inner wall of the base in a circular array. A bracket is also fixedly connected to the side of the six connecting plates away from the base.

[0007] Preferably, the main body of the bracket is arranged longitudinally, and a connecting block is fixedly connected to the side of the bracket near the base, and the connecting block has a structure that protrudes from the outer bracket.

[0008] Preferably, each connecting block has two opposing fixed connections on its outer side, and the connecting block and the locking blocks together form a connecting structure.

[0009] Preferably, a support ring is fixedly connected to the inner side of the bracket, and a lens is embedded in the inner side of the support ring.

[0010] Preferably, a cover plate is installed at the top of the base. The main body of the cover plate is a ring structure, and an insert plate is fixedly connected to the bottom surface of the cover plate. The insert plate is a magnetic structure.

[0011] Preferably, a cylinder is fixedly connected to the top surface of the cover plate, and a longitudinally arranged guide groove is provided on the inner wall of the cylinder.

[0012] Beneficial effects

[0013] This invention provides a front lens barrel with an anti-deformation structure. Compared with the prior art, it has the following advantages:

[0014] The front lens barrel with an anti-deformation structure is equipped with reinforcing ribs fixedly connected to the base. The interior of the reinforcing ribs has through slots arranged in a ring array, which reduces the overall weight of the reinforcing ribs. By embedding the reinforcing ribs inside the base, the base is supported against deformation, thus achieving a more practical purpose.

[0015] The front lens barrel with an anti-deformation structure is equipped with a bracket and a connecting block fixedly connected to the inside of the connecting plate. When the lens is installed in the inner position of the support ring, the connecting block and the locking block fixedly connected to the outside of the bracket can be inserted into the guide groove opened in the barrel to achieve efficient fixing, support and limit operation of the lens, thereby achieving a more practical purpose.
