An insulating pull rod assembly

Abstract

The present invention discloses an insulation pull bar assembly comprising an inner joint, an outer joint and an insulation pull bar. The circumferential outside walls of the left and right ends of the insulation pull bar are provided with two insertion blocks respectively, the two insertion blocks are symmetrically arranged, upper ends of the outside walls of the left and right ends of the insulation pull bar are provided with an installation groove respectively, each insulation groove is internally fixedly provided with a sprig, and the upper end of each spring is fixedly connected with a positioning block. One end of the inner joint is provided with an installation sleeve, one end of the installation sleeve is a hollow structure with one end opened, the inside wall of the installation sleeve is provided with two symmetric insertion grooves, the upper end of the inside wall of the installation sleeve is provided with a positioning groove, the two insertion blocks of the left end of the installation pull bar are inserted into the insertion grooves in one-to-one correspondence, and the positioning block of the left end of the insulation pull bar is installed in the positioning groove of the installation sleeve. The inner joint and the outer joint have the same structure. The right end part of the insulation pull bar is installed in the installation sleeve on the outer joint.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to an insulating pull rod assembly. Background technique [0002] In the prior art, the insulating pull rods used in various switchgears are mainly made of ceramic insulating structures, which are too bulky and bulky, with screw connections at both ends, requiring special tooling, and the insulation performance is not ideal. As the switchgears become smaller and smaller The existing insulating rods have limited the development trend of switchgear. Contents of the invention [0003] In order to solve the problems existing in the background technology, the object of the present invention is to provide an insulating pull rod assembly, which can be installed quickly and accurately and connected reliably. [0004] In order to realize the above-mentioned purpose of the invention, the present invention adopts the technical scheme as follows: [0005] An insulat...
