Description

an eyepiece tube

technical field

The utility model relates to parts of a camera module, in particular to an eyepiece barrel.

Background technique

In the related art, the eyepiece barrel is used to connect the circuit board and the lens barrel. The existing eyepiece barrel has a relatively simple structure, but lacks a fixed design, which easily causes large errors in the fixing and installation of the eyepiece barrel, which in turn affects the operation of the entire camera module. Effect.

Utility model content

The main purpose of the present utility model is to overcome the deficiency of the above-mentioned background technology, and provide an eyepiece tube, which is convenient for fixing the eyepiece tube.

The above-mentioned purpose is achieved through the following technical solutions:

An eyepiece tube, comprising a bottom tube and a sleeve arranged in the middle of the top surface of the bottom tube, the bottom tube and the sleeve are integrally formed and communicate with each other, and the inner wall surface of the lower end of the sleeve is provided with a The screw thread connected with the main lens barrel is respectively provided with rectangular fixing grooves on both sides of the first outer surface of the sleeve, and the length of the fixing grooves extends along the height direction of the sleeve. The two sides of the second outer surface adjacent to the outer surface are respectively provided with fixing bosses, and fixing holes are arranged in the fixing bosses, and the two sides of the second outer surface are connected to the adjacent first outer surface through arc-shaped depressions respectively. The side and the third outer side are connected.

In some embodiments, a plurality of stepped holes are provided on the periphery of the sleeve and the top surface of the bottom cylinder along the circumference.

In some embodiments, four corners of the top surface of the sleeve are respectively connected with posts, and connection holes are provided in the connected posts.

In some embodiments, a limiting hole is provided on the top surface of the sleeve beside at least one of the connecting posts.

The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects:

1. The eyepiece tube of the present invention has a relatively simple overall structure, and the fixing groove and the fixing boss can facilitate the fixing of the eyepiece tube, so as to reduce the installation error of the eyepiece tube.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Embodiment 1: As shown in Fig. 1, Fig. 2 and Fig. 3, this embodiment is an eyepiece tube 1, comprising a bottom tube 11 and a sleeve 12 arranged in the middle of the top surface of the bottom tube 11, the bottom tube 11 The tube 11 and the sleeve 12 are integrally formed and communicate with each other. The integrally formed design can reduce the production process of the eyepiece tube, reduce manpower and material resources, and improve the price competitiveness of the product. On the inner wall surface of the lower end of the sleeve 12 A screw thread 120 for connecting with the main lens barrel is provided to facilitate the connection between the eyepiece barrel 1 and the main lens barrel. Preferably, the main lens barrel and the eyepiece barrel 1 are screwed in from the position of the marking line to the end point where the marking line and The marking lines are overlapped into 180°, and rectangular fixing grooves 121 are respectively arranged on both sides of the first outer surface of the sleeve 12, and the length of the fixing grooves 121 extends along the height direction of the sleeve 12. Both sides of the second outer surface adjacent to the first outer surface are respectively provided with fixing bosses 122, and fixing holes 1220 are arranged in the fixing bosses 122, and the two sides of the second outer surface respectively pass arc-shaped The depression 123 is connected with the adjacent first outer surface and the third outer surface. The overall structure of the eyepiece tube 1 of this embodiment is relatively simple. The fixing groove 121 and the fixing boss 122 can facilitate the fixing of the eyepiece tube 1, thereby reducing the The installation error of the small eyepiece tube.

Preferably, a plurality of stepped holes 110 are provided on the periphery of the sleeve 12 and the top surface of the bottom tube 11 along the circumference, so as to facilitate the connection and fixation between the eyepiece tube 1 and the circuit board.

Preferably, the four corners of the top surface of the sleeve 12 are respectively connected with posts 124, and connection holes 1240 are provided in the connected posts 124, so as to facilitate the connection and fixation of the eyepiece tube and other parts.

Preferably, a limit hole 125 is provided on the top surface of the sleeve 12 beside at least one of the connecting posts 124 , so as to facilitate the limit and connection of the eyepiece tube 1 .

What have been described above are only some embodiments of the present utility model. For those skilled in the art, without departing from the inventive concept of the present utility model, several modifications and improvements can be made, and these all belong to the protection scope of the present utility model.
