Abstract
The utility model discloses a glue-dispensing fixed structure of a filter on a lens barrel. An annular groove for containing the glue is arranged on the matched surface of the lens barrel and the filter; and the filter is directly fixed on the lens barrel by means of the glue in the annular groove. Compared with the complicated technology in the prior art that a back lock cover is used for glue dispensing and locking, the back lock cover can be omitted, the production cost is reduced, complexity of the technology is lessened, and the production efficiency is improved.
Description
Technical field
The utility model relates to the glue-dispensing fixing structure of optical filter on a kind of lens barrel.
Background technology
In the industry, the method for fixed lens bottom optical filter 2 is placed on optical filter 2 first the camera lens bottom of lens barrel 1 as depicted in figs. 1 and 2 on lens barrel 1, then locking closure 3 after optical filter 2 is added a cover, rear locking closure 3 and optical filter 2 is fixing, put again glue rear locking closure 3 and lens barrel 1 is locked, make optical filter 2 fixing.
Above-mentioned fixing method is too loaded down with trivial details, greatly reduces production efficiency.The base this, the inventor develops the novel spot gluing fixed sturcture of optical filter on a kind of lens barrel, this case produces thus.
The utility model content
The purpose of this utility model is to provide the glue-dispensing fixing structure of optical filter on a kind of lens barrel, to reduce production costs, reduces process complexity, enhances productivity.
In order to reach above-mentioned purpose, solution of the present utility model is:
The glue-dispensing fixing structure of optical filter on the lens barrel forms the ring groove that holds glue at the mating surface of lens barrel and optical filter, and optical filter directly is fixed on the lens barrel by the glue in the ring groove.
Be recessed to form the step that optical filter is installed on the described lens barrel, form the ring groove that holds glue on the step surface.
After adopting such scheme, the utility model has increased ring groove, by slowly the solidifying, shrinks of glue, optical filter is directly inhaled firmly consolidated on the mating surface of lens barrel.The utility model is compared with the locked complicated technology of rear locking closure point glue with prior art, can save rear locking closure, reduces production costs, and reduces process complexity, enhances productivity.

Label declaration
Embodiment
As shown in Figure 3 and Figure 4, the glue-dispensing fixing structure of optical filter on the lens barrel that the utility model discloses, at the mating surface formation ring groove 11 of lens barrel 1 with optical filter 2, be used for holding glue, for convenient the installation fixed, this embodiment is recessed to form the step 12 that optical filter 2 is installed at lens barrel 1 first, and the face at step 12 forms the ring groove 11 that holds glue again.
The utility model is used for optical filter 2 fixedly the time, optical filter 2 is put into after the lens barrel 1, four glue of up and down point at optical filter 2 edges, glue can flow to along the mating surface of optical filter 2 and lens barrel 1 in the ring groove 11 of bottom, owing to used glue can shrink along with solidifying, so along with slowly solidifying of glue, optical filter 2 is just directly inhaled solid on the mating surface of lens barrel 1 firmly.
The above only is an embodiment of the present utility model, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
Claims (2)
1. the glue-dispensing fixing structure of optical filter on the lens barrel is characterized in that: the mating surface at lens barrel and optical filter forms the ring groove that holds glue, and optical filter directly is fixed on the lens barrel by the glue in the ring groove.
