Decoration tool with automatic disconnecting link closing structure for building decoration

Abstract

The invention relates to the technical field of disconnecting links, in particular to a decoration tool with an automatic disconnecting link closing structure for building decoration. The decoration tool comprises a disconnecting link porcelain base, a connecting seat is fixedly connected to the central position of the top end of the disconnecting link porcelain base, a pull rod is hinged to the top end of the connecting seat, and an abutting block is fixedly connected to the central position of the surface of the pull rod. By arranging a first limiting mechanism and a pushing mechanism, whenthe pull rod is pulled downwards to drive the abutting block to move, the abutting block applies pressure to the inclined face at the right side of the first connecting block, so that the first connecting block is pushed to move outwards; and when the abutting block moves to the lower end of the first limiting block, a first sliding block is pushed to move through the elastic force of a first spring, the first sliding block drives a second rack to move through a gear in the moving process, the second rack drives the first connecting block to move through a second sliding block in the moving process, and the first connecting block enables the first limiting block to be attached to the surface of the abutting block in the moving process, and therefore the abutting block is limited.

Description

technical field [0001] The invention relates to the technical field of knife gates, in particular to a decoration tool with an automatic knife gate closing structure for building decoration. Background technique [0002] Knife switch is a kind of manual switch of electric power equipment. It is also called switch knife. It is generally used for low-voltage power. It can be divided into single-phase switch and three-phase switch. There are various specifications according to different applications. Generally, voltage and current are marked. , such as 220 volts, 16A, which means that it is suitable for 220 volts, and the current does not exceed 16 amps. Generally, it is composed of a porcelain base, a plastic cover, and copper parts. The upper part is the inlet port, the lower part is the outlet port, and the fuse is installed in the middle , the function of the knife switch is to form an obvious disconnection point between the maintenance equipment and the live equipment duri...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem existing in the prior art that the factory needs to manually push the knife switch to close after the opening and maintenance is completed, and the knife switch cannot be quickly lifted and closed. In order to solve the problem of inconvenience, a kind of decoration tool with automatic closing structure of knife switch is proposed for building decoration
