In order to solve the problems of the technologies described above, the lens cap that the utility model discloses a kind of automatic unlatching or close, comprise cover plate part, it is characterized in that, be provided with the motor, gear reduction, the guide rod that connect successively in the casing, the end of described casing is provided with plate washer or end cap respectively, and the wall of described casing is provided with opening; Described cover plate part is the bent plate shape, and an end of described cover plate part is connected with guide rod, and the other end of described cover plate part stretches out from the opening part of described casing, and the power supply of described motor links to each other with the power supply of camera lens place equipment.
Box house is provided with support described in the utility model, the output terminal of described gear reduction passes from support, one end of described guide rod adopts pin to connect with being connected of described gear reduction, the other end of described guide rod is connected with an end of casing, described cover plate part comprises the transverse bar that connects successively, the bidirectional modulation plate, longitudinal rod and cover plate, described cover plate part and guide rod are for being threaded, it is rounded tabular that described cover plate is positioned at an end that stretches out casing, side at described circular slab is provided with sealing gasket, described casing adopts with described end cap and is threaded, described casing and described side plate are structure as a whole, and the screw that is used for fixing support is set between described support and the described housing plate.
Compared with prior art, the beneficial effects of the utility model are:
(1) since on the utility model lens cap the power supply of motor link to each other with the power supply of camera lens place equipment, so lens cap can or close and open automatically or close with the unlatching of equipment, and is simple to operation;
(2) be the gear reduction that driven by motor has rational ratio of gear owing to what adopt, so the lens cap stable drive, the reliability height can not produce adverse consequences;
(3) side that contacts with camera lens of lens cap is provided with the sealing gasket that adopts the high-performance rubber material, and described sealing gasket is not yielding and aging, good seal performance;
(4) can adopt ABS plastic on most of parts in the utility model lens cap, in light weight, the intensity height, good toughness, smooth surface is attractive in appearance, is difficult for aging;
(5) the utility model lens cap is rational in infrastructure, and it is 120 millimeters that its physical dimension can be controlled in length, and diameter is in 44 millimeters scopes, overall weight has only 0.25 kilogram, do not need very large space during installation, very light in weight can guarantee to use the normal and safety of the equipment of the utility model lens cap.
