Quick coupler, inner joint of ball-type video camera and ball-type video camera

Abstract

The invention provides a ball-type video camera which comprises a mounting bracket and a ball-type video camera body, wherein an inner joint extends upwards from the ball-type video camera body; the ball-type video camera further comprises a quick coupler; the quick coupler comprises an external thread round tube connected with an inner thread of the mounting bracket, and a circular ring coaxially connected with the external thread round tube; a plurality of first screw holes are arranged on the end face of the circular ring; a limiting platform is arranged on the inner wall of the circular ring; the inner joint comprises a cylindrical boss, of which the centre is provided with a first combined cable; the first combined cable extends from the upper surface of the cylindrical boss and is connected with a second combined cable in the mounting bracket; second screw holes corresponding to the first screw holes are arranged on the end face of the cylindrical boss; a limiting flat plate corresponding to the limiting platform is formed on the end face of the cylindrical boss, and the inner joint is inserted into the quick coupler and connected through the first screw holes and the second screw holes via screws.

Description

technical field [0001] The invention relates to a dome camera, in particular to a quick-fit joint for a dome camera capable of safely and quickly connecting a bracket, a connection inner cover of the dome camera and the dome camera. Background technique [0002] The existing dome camera includes a dome camera body, an inner joint is provided on the dome camera body corresponding to one end connected to the bracket, and the inner joint is inserted into the housing of the bracket and connected by a plurality of screws. [0003] First of all, when installing the existing dome camera, it is necessary to align all the screw holes on the inner connector and the bracket, so that the screws can be installed in the screw holes. Since the dome camera is usually installed at a relatively high place, and the dome camera body has a certain weight, it is difficult to align the screw holes. [0004] Secondly, during installation and maintenance, engineers generally need to perform wiring ...

AI Technical Summary

Problems solved by technology

Since the dome camera is usually installed at a relatively high place, and the dome camera body has a certain weight, it is difficult to align the screw holes

[0004] Secondly, during installation and maintenance, engineers generally need to perform wiring and other operations inside the dome camera. Because the internal space of the dome camera is relatively small, wiring is very inconvenient, and camera damage caused by misoperation is more likely to occur.

[0005] In addition, there is no second safety protection measure for the installed dome camera at high altitude, so there are also great safety hazards for ground personnel and vehicles.
