The convenient and efficient module focusing tool has the advantages of simple structure, small volume, convenient operation and the like.
Description
[technical field]
The utility model relates to a kind of convenience, efficient module focusing tool.
[background technology]
In the production run of optical lens and module, Focussing technique is absolutely necessary when producing, when mobile phone is taken pictures to different object distances, the rear burnt of camera lens can be not identical, if the back focal length of camera lens do not adjust to the right place when producing can cause take pictures unclear, only have by rear Jiao of optical lens be adjusted to correct distance could detector lens and module whether qualified.
Secondly, existing focusing tool uses difficult focusing, the bad aligning in center, the bad grasp of when focusing flatness, take up room large, focusing efficiency is slow, focusing dynamics is inhomogeneous, tool takes off back focal length from drift, factors causes having a strong impact on result and the production efficiency of measurement.
Have, need the tool that buttresses of extreme care to focus, otherwise will cause camera lens discontinuity during existing tool focusing, evaluation result is inaccurate, and the efficiency of therefore focusing is very low.Tool puts up the focusing draw-in groove that need to look for camera lens, and in searching process, operator needs the searching of croucs, and long-time so operation employee fatigue strength increases greatly.
[utility model content]
The purpose of this utility model is overcome the deficiencies in the prior art and provide a kind of simple in structure, and volume is little, easy to operate efficient module focusing tool.
For above-mentioned purpose, the utility model by the following technical solutions:
Convenient, efficient module focusing tool, it is characterized in that comprising fixed muffle 1, at fixed muffle 1 outside surface, be arranged with lock trim ring 2 and can relatively rotate around fixed muffle 1, at lock, be fixedly connected with focusing knob 3 on trim ring 2, at the middle part of focusing knob 3, be provided with and stretch into fixed muffle 1 in the also button pawl 31 of adjustable module 4 focal lengths.
Convenience as above, efficient module focusing tool, is characterized in that matching with module 4 external surface shape in the inner wall shape of described fixed muffle 1, on fixed muffle 1 upper inside wall surface, is also provided with to the internal projecting ring 11 on projecting inward withstood on module.
Convenience as above, efficient module focusing tool, it is characterized in that being also provided with outwardly outer bulge loop 12 at the outer wall upper face of described fixed muffle 1, in the inwall bottom of described lock trim ring 2, be provided with to projecting inward pressure ring 21, pressure ring 21 tops are pressed on outer bulge loop 12 and can make relative sliding.
Convenience as above, efficient module focusing tool, it is characterized in that being provided with external thread 22 on the outer wall of described lock trim ring 2, on the inwall of focusing knob 3, be provided with internal thread 32, external thread 22, internal thread 32 interconnect and make to lock trim ring 2 and be fixed together with focusing knob 3.
Convenience as above, efficient module focusing tool, is characterized in that described button pawl 31 is for being located at a plurality of projections of the interior ring of focusing knob 3 bottom.
The beneficial effects of the utility model have:
Focusing knob of the present utility model, fixed muffle, lock trim ring, do not need three Assembly of the parts alignment directly tool to be enclosed within to rotate focusing knob on module just can realize focusing to just realizing together focusing.
In addition, there is an internal projecting ring fixed muffle inside, utilizes the internal projecting ring of fixed muffle inside to coordinate module end face as the strong point, thereby realize when focusing plane fulcrum, holds the weight of focusing knob and is not pressed on camera lens, can high-level efficiency, focus fast.During operation, only need singlehanded rotating jig focusing.

[embodiment]
Below in conjunction with accompanying drawing and embodiment, the utility model is elaborated:
As shown in the figure, convenient, efficient module focusing tool, includes fixed muffle 1, at fixed muffle 1 outside surface, is arranged with lock trim ring 2 and can relatively rotates around fixed muffle 1, locks trim ring 2 and can rotate around fixed muffle 1.On described lock trim ring 2, be fixedly connected with focusing knob 3, at the middle part of focusing knob 3, be provided with and stretch in fixed muffle 1 and the button pawl 31 of adjustable module 4 focal lengths.Rotate focusing knob 3 by hand, the button pawl 31 of focusing knob 3 will rotate with camera lens, and the relative position of camera lens and module will change, thereby realize, focuses.
Furthermore, in the inner wall shape of described fixed muffle 1, match with module 4 external surface shape, on fixed muffle 1 upper inside wall surface, be also provided with to the internal projecting ring 11 on projecting inward withstood on module.Direct like this fixed muffle 1 is enclosed within to module 4, utilize the internal projecting ring 11 of fixed muffle inside to coordinate module end face as the strong point, thereby realize when focusing plane fulcrum, hold the weight of focusing knob and be not pressed on camera lens, can high-level efficiency, focus fast.During operation, only need singlehanded rotating jig focusing.
As the optimal way of the present embodiment, at the outer wall upper face of described fixed muffle 1, be also provided with outwardly outer bulge loop 12, in the inwall bottom of described lock trim ring 2, be provided with to projecting inward pressure ring 21, pressure ring 21 tops are pressed on outer bulge loop 12 and also can be made relative sliding.Lock trim ring 2 does not change with fixed muffle 1 upper and lower position like this, and lock trim ring 2 is just done relative rotation with fixed muffle 1.
As the optimal way of the present embodiment, on the outer wall of described lock trim ring 2, be provided with external thread 22, on the inwall of focusing knob 3, be provided with internal thread 32, external thread 22, internal thread 32 interconnect and make to lock trim ring 2 and be fixed together with focusing knob 3.Assembling is more convenient like this, more saves operation.
As the optimal way of the present embodiment, described button pawl 31 is for being located at a plurality of projections of the interior ring of focusing knob 3 bottom, and projection is generally 3-6, is 4 in the present embodiment.
