Problems solved by technology

There are already some lens covers that can be opened and closed automatically in the prior art, but these automatically opened and closed lens covers are not only complicated in structure, but also mostly do not have the switch self-locking function, thus affecting the use of the lens cover.

Abstract

The present invention relates to an electric-controlled lens cover which is used in the field of optical device and has a self-locking function. The electric-controlled lens cover comprises a lens cover and a driving cabinet. The lens cover is connected with the output axis of the driving cabinet through a rock arm. The difference is that the driving cabinet comprises a cabinet and a self-lockingdriving device provided in the cabinet. The self-locking driving device comprises a grooved pulley pin self-locking mechanism which is connected with the output axis. The driving input end of the grooved pulley pin self-locking mechanism is connected with the driving motor through the transmission chain. The electric-controlled lens according to the invention has the following beneficial effects:1. switching and self-locking realized by the electric-controlled cover of grooved pulley pin self-locking mechanism, resistance to the strong exterior shake, strong self-locking function, high usingreliability, effective prevention for the entering of wind, rain, sand and dust into the lens when the lens cover is closed, lens protection; 2, simple and compact structure, reasonable arrangement, facility for matching with the optical camera-shooting device and the photograph-taking device; and 3. excellent overload protection function.

Description

technical field [0001] The invention relates to an electronically controlled lens cap with self-locking function used in the field of optical instruments. The lens cap is especially suitable for a lens at high altitude or a camera lens in a long-term environment with wind, rain, sand, dust and severe vibration. Background technique [0002] At present, there are more and more lenses at high altitude and in the environment of wind, rain, sand, dust or severe vibration. In order to maintain the clarity of the lens and protect the lens from pollution, it is necessary to install a lens cover on the lens so that the lens can be effectively protected when it is not in use. protection of. There are some lens covers that can be opened and closed automatically in the prior art, but these automatically opened and closed lens covers are not only complicated in structure, but also mostly do not have a switch self-locking function, thereby affecting the use of the lens cover. Conten...
