Filter fixing connecting assembly with self-locking structure

Abstract

The invention relates to the technical field of filters, in particular to a filter fixing connecting assembly with a self-locking structure. The assembly comprises a filter body, a mounting cover being arranged in the filter body, fixing columns being fixedly connected to the surface of the mounting cover, a top plate being fixedly connected to the top ends of the fixing columns, the fixing columns being in two groups, a lifting rod being inserted into the surface of the top plate, and a fixing ring being fixedly connected to the bottom end of the mounting cover; a magnetic suction cylinder, mounted on the inner bottom wall of the filter body, and a mounting bottom ring being arranged at the bottom end of the magnetic suction cylinder. According to the invention, when the two groups of magnetic suction rods are adsorbed into the magnetic suction cylinders. The device can realize a certain self-locking function, the problem that an existing connecting assembly cannot realize the self-locking function is solved, the stability of the filter during use is ensured, the mounting cover is automatically mounted on the surface of the filter body through the cooperation between the assemblies, and the connection stability is greatly improved.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a connection assembly with a self-locking structure for fixing filters. Background technique [0002] A filter is a frequency selection device that can pass specific frequency components in a signal and greatly attenuate other frequency components. Using this frequency selection function of the filter, it can filter out interference noise or perform spectrum analysis, in other words , any device or system that can pass a specific frequency component in a signal and greatly attenuate or suppress other frequency components is called a filter. A filter is a device that filters waves. "Wave" is a very broad term. Physical concept, in the field of electronic technology, "wave" is narrowly limited to specifically referring to the process of describing the fluctuation of the value of various physical quantities with time. This process is converted into a time function of voltage or curr...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a connection assembly with a self-locking structure for fixing the filter, so as to solve the problem that the existing filter proposed in the background art is fixed through the connection assembly through some existing fixing pieces To fix the filter, the fixing effect is relatively general. If you can easily open the filter after fixing, it may affect the normal use of the filter, and the filter cannot achieve a certain self-locking function problem
