Abstract
The utility model relates to an assembling structure for a single lens of a laser point light source. The single lens assembling structure comprises a housing and a lens installed in the housing; an annular positioning step that is coaxial with the housing is arranged on the inner wall of the housing; and an inclined dispensing surface is arranged on a lens mounting end of the housing. According to the utility model, the structure is simple; a few raw materials are employed and only the metal housing and the lens are needed, so that the cost is saved; and he dispensing is carried out conveniently, rapidly, fixedly and firmly and the lens is not polluted due to the dispensing, thereby substantially improving the lens assembling efficiency.
Description
Technical field
The utility model relates to the optical devices technologies field, particularly relates to a kind of single element lens assembly structure for laser point light source.
Background technology
Traditional optical lens fixed sturcture adopts union (screwed)bonnet (UB structure, interference to be press-fitted compressing structure and side opening point glue+spring top clamping structure usually, wherein side opening point glue+spring top clamping structure is the most frequently used a kind of structure in the single element lens fixed sturcture, this structure comprises metal shell, single element lens and spring, described lens are contained in the metal shell, and some glue is further fixing then (to put glue position correspondence in the side-walls of lens) in the some glue hole of metal shell with the spring top clamping location first.The problem that this structure exists is: 1. easily cause lens to scratch in the spring top clamping process and pollute; 2. lens were packed into deeply, and assembling inconvenience affects efficiency of assembling; 3. side opening point glue is not easy to operate, inefficiency; 4. the bad difficulty of reprocessing.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of simple in structure, and process and assemble is convenient, the single element lens assembly structure that is used for laser point light source that cost is low.
The technical scheme that realizes the utility model purpose is: a kind of single element lens assembly structure for laser point light source comprises shell and installation lens in the enclosure; The inwall of described shell is provided with the positioning step with the coaxial annular of shell; The lens installation end of described shell is provided with a glue inclined-plane.
Distance between the lower limb on described some glue inclined-plane of technique scheme and the coboundary of positioning step is 2/3rds of lens thickness.
The internal diameter of the described positioning step of technique scheme is identical with the aperture of lens light hole.
Also has ring groove on the outer wall of the described shell of technique scheme.
After adopting technique scheme, the utlity model has following positive effect:
Of the present utility model simple in structure, raw materials is less, only needs metal shell and lens, saves cost, puts the convenient and swift fixation of glue and can not pollute lens because of a glue, thereby can significantly improve lens arrangement efficient.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is structural representation of the present utility model;
1. shells among the figure, 11. positioning steps, 12. glue inclined-planes, 13. ring grooves, 2. lens.
Embodiment
(embodiment 1)
See Fig. 1, the utility model comprises shell 1 and the lens 2 that are installed in the shell 1; The inwall of shell 1 is provided with the positioning step 11 with the coaxial annular of shell 1, and the internal diameter of positioning step 11 is identical with the aperture of lens 2 light holes; Lens 2 installation ends of shell 1 are provided with a glue inclined-plane 12, and the distance between the lower limb on some glue inclined-plane 12 and the coboundary of positioning step 11 is 2/3rds of lens 2 thickness.Also has ring groove 13 on the outer wall of shell 1.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
