Abstract

The utility model relates to a camera lens, especially to a camera lens with a square optical filter. The camera lens comprises a lens barrel (1), a plastic lens (2), a first plug (3), the square glass optical filter (4) and a second plug (5), wherein the plastic lens (2) is sleeved on the front end of the lens barrel (1) and also sleeved on the first plug (3), the square glass optical filter (4) is arranged on the first plug (3), and the second plug (5) is arranged on the square glass optical filter (4). The square optical filter is directly added into a sharpener, so that sharpening of the optical filter is not required, thereby saving production cost of enterprise, and shortening production time; and in the post assembling process, the square optical filter is easy to fix, which provides convenience for product in the next step.

Description

A kind of camera lens with box filter

Technical field:

The utility model relates to a kind of camera lens, is specifically related to a kind of camera lens with box filter.

Background technology:

In present camera lens production run on the market, needed step is a lot, in assembling camera lens process, use a kind of optical filter, but the camera lens optical filter of producing on the market now is mostly circular filter, when dressing up camera lens, filter set can carry out cutting process, be the box filter that first cuts into solid shape in original technique, by the box filter polishing, becoming circular filter, expended like this material afterwards, increased production cost, and relatively lost time.

The utility model content:

The purpose of this utility model is to provide a kind of camera lens with box filter, it directly adds box filter in grinding tool, need to be in the polishing of carrying out optical filter, saved the production cost of enterprise, also shortened the production time simultaneously, and in the later stage assembling process, be transformed into square optical filter easily fixing, facilitated next step production.

In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises barrel 1, glass lens 2, the first plug 3, square glass optical filter 4 and the second plug 5, the front end sleeve of barrel 1 is connected to glass lens 2, be socketed with the first plug 3 in glass lens 2, be provided with square glass optical filter 4 on the first plug 3, be provided with the second plug 5 on square glass optical filter 4.

The utlity model has following beneficial effect: it directly adds box filter in grinding tool, need to be in the polishing of carrying out optical filter, saved the production cost of enterprise, also shortened the production time simultaneously, and in the later stage assembling process, be transformed into square optical filter easily fixing, facilitated next step production.

The accompanying drawing explanation:

Fig. 1 is structural representation of the present utility model;

The structural representation that Fig. 2 is prior art in background technology.

Embodiment:

With reference to Fig. 1-2, this embodiment is taked following technical scheme: it comprises barrel 1, glass lens 2, the first plug 3, square glass optical filter 4 and the second plug 5, the front end sleeve of barrel 1 is connected to glass lens 2, be socketed with the first plug 3 in glass lens 2, be provided with square glass optical filter 4 on the first plug 3, be provided with the second plug 5 on square glass optical filter 4.

This embodiment has following beneficial effect: it directly adds box filter in grinding tool, need to be in the polishing of carrying out optical filter, saved the production cost of enterprise, also shortened the production time simultaneously, and in the later stage assembling process, be transformed into square optical filter easily fixing, facilitated next step production.
