Description

Reset stop device for camera

Technical Field

The invention belongs to the field of monitoring cameras, and particularly relates to an anti-shake camera resetting and stopping device.

Background

At present, a long-focus large-zooming camera is widely applied in the field of video monitoring in the security industry. However, the long-focus large-zooming camera is installed at a higher position, the distance of a monitored target is far, and in windy weather, the video is blurred due to the shake of the camera, so that an anti-shake measure is required for the camera. Present anti-shake has mechanical anti-shake and electronic anti-shake, and wherein mechanical anti-shake needs to use 2 ~ 3 anti-shake motors to the camera suspension. When no wind and no anti-shake is needed, the position of the camera stops at a random position, so that the monitoring position deviates, and the monitoring effect is poor.

Furthermore, one side of the screw nut is provided with a stop optical coupler catch used for matching with an optical coupler to control the position of the screw nut.

Further, a linear bearing matched with the guide shaft is arranged on the screw nut, and the linear bearing and the screw nut are fixed through an elastic check ring for a shaft.

Furthermore, the height of one side of the motor support provided with the round hole is higher than that of the other side opposite to the round hole.

Furthermore, the mount is the L type, and the mount bottom is equipped with first angle adjustment motor, the side of mount, the below position of motor is equipped with second angle adjustment motor.

Compared with the prior art, the invention has the beneficial effects that: through the cooperation of the V-shaped groove plates on the first stop piece and the second stop piece, the moving part can be quickly reset, and when the locking is released, no extra resistance exists, so that the camera can be accurately positioned at the initial position.
