Description
Technical field
The utility model relates to the lens cap field, relates in particular to a kind of automatic mirror skull.
Background technology
Most digital camera lens lid all separates with camera lens on the market now; when the user will use camera to take pictures; need earlier lens cap to be taken off the back and kept properly lens cap; open camera power supply again; camera just can be taken pictures. and well-known; the great advantage of camera is exactly can catch to grab excellent moment; if the user is using catching of camera to grab fine moment; the user also needs earlier lens cap to be taken off and takes good care of; then just opening camera power supply just takes pictures; such action; will make the fan lose the moment of a lot of excellences. perhaps some user takes pictures for the use camera of prestissimo; just lens cap is discarded after taking off lens cap; tend to after they have taken photo, find losing of lens cap like this; the user need buy lens cap again. and this time and money that will waste the user removes to buy new lens cap; and after the user has lost lens cap; generally can not buy 1 new lens cap len of returning immediately; might make camera lens lose the protection of short-term like this; infringement just appears in camera lens possibly that lost protection; camera lens is again the important component part of camera; if infringement appears in camera lens under the protection that does not have lens cap, may scrapping of camera will be caused.
The utility model content
It is a kind of without repeated disassembled and assembled, the convenient automatic mirror skull of use that the purpose of this utility model is to provide.
Complete skill scheme of the present utility model is, a kind of lens cap, comprise an outer ring and at least two lens cap blades, one end activity of described lens cap blade be connected top, described outer ring, the junction of described lens cap and described outer ring is provided with an axle, described axle is provided with a spring, and described each lens cap vane group is circular altogether.
Preferably, described lens cap blade is 3.
Optionally, the interconnective limit of described lens cap blade is a straight line.
Optionally, the interconnective limit of described lens cap blade is a curved side.
Therefore a kind of lens cap of the utility model has following beneficial effect:
A kind of lens cap comprises an outer ring and at least two blades, the activity of lens cap blade be connected top, outer ring, outer ring and lens cap junction are provided with an axle, axle is provided with a spring, during use, as long as lens cap is installed on the camera lens, when opening camera power supply, camera lens can promote the lens cap blade and open; After camera is finished using, the camera lens withdrawal, lens cap blade meeting automatic drawing back under the effect of spring force has avoided lens cap to roll over dress repeatedly then, uses convenient.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of 1 one kinds of lens caps of embodiment;
Fig. 2 is the structural representation of 1 one kinds of lens cap blades of embodiment;
