As shown in fig. 10 and 11, in a monitoring camera apparatus according to a fifth embodiment of the present invention, the link mechanism 3 includes a rotating lever 301 and an auxiliary lever 302, the rotating lever 301 is inclined with respect to the axial direction of the camera module 2, the middle portion of the rotating lever 301 is rotatably connected to the camera module 2, and both ends of the rotating lever 301 are rotatably connected to the rotating end 12a of the bottom cover 12 and the top cover 11, respectively; the auxiliary lever 302 and the rotating lever 301 are provided at an interval, and both ends of the auxiliary lever 302 are rotatably connected to the camera module 2 and the top cover 11, respectively.
When dismantling and maintaining, end cover 12 moves down under self action of gravity and rotates simultaneously, can open camera module 2's bottom, and end cover 12 drives dwang 301 and rotates, and the top of dwang 301 moves up 11 liftings in top cap, and auxiliary rod 302 can constitute crank rocker mechanism with dwang 301 to guarantee the stability that 11 removals in top cap, make top cap 11 can smooth steady rebound.
In this embodiment, the rotation of the rotation lever 301 is utilized, so that the bottom cover 12 and the top cover 11 can be moved away from or close to each other, and the top and the bottom of the camera module 2 can be opened at the same time, so that the camera module 2 is completely exposed, and the camera module 2 is conveniently maintained.
The above embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
