Magnetic control type elastic pin easy to assemble and disassemble

Abstract

The invention relates to the technical field of spring pins, in particular to a magnetic control type elastic pin easy to assemble and disassemble. The magnetic control type elastic pin comprises an external main barrel and a lateral positioning pipe. According to the magnetic control type elastic pin easy to assemble and disassemble, an internal control barrel controlled by a lateral rotating shaft is inserted into an external main barrel, a lateral storage groove internally provided with an arc-shaped external extrusion plate is formed in the outer side of the external main barrel, an external permanent magnet on an arc-shaped external extrusion plate is matched with an internal permanent magnet on the arc-shaped surface of the outer side of the internal control barrel, so that the arc-shaped external extrusion plate is controlled to stretch out and draw back, a magnetic control mode is adopted, operation is easy and convenient, and damping performance and stability are greatly improved; the arc-shaped external extrusion plate, an external telescopic box, the external permanent magnet, an internal permanent magnet and a middle permanent magnet all adopt a detachable mounting mode, so that the later loading, unloading and maintenance are convenient, and the use cost is reduced; and an arc-shaped external extrusion plate and an elastic extrusion stretching mechanism are matched with each other, so that the assembling outer diameter of the pin is adjusted, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of spring pins, in particular to a magnetically controlled elastic pin which is easy to assemble and disassemble. Background technique [0002] Architectural curtain wall is the outer wall enclosure of modern buildings. It is not load-bearing and hangs up like a curtain, so it is also called "curtain wall". It is a light-weight wall with decorative effect commonly used in modern large-scale and high-rise buildings. Composed of a panel and a supporting structure system, it can have a certain displacement capacity relative to the main structure or itself has a certain deformation capacity, and does not bear the role of the main structure. The building envelope structure or decorative structure, and the elastic pin is a kind of curtain wall. Connecting accessories for positioning, connecting and fixing; it has good elasticity and shear resistance performance, simple assembly method and convenient operation. ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: In order to solve the problems existing in the above-mentioned background technology, an improved magnetically controlled elastic pin that is easy to install and disassemble is provided to solve the problem that most of the elastic pins currently on the market have simple and fixed structures and a single-standard elastic pin structure. It cannot be adjusted, which leads to a very limited scope of application, and the stability of the internal assembly is insufficient, and it is also very inconvenient to assemble and disassemble.
