A spring-type guide rail limit device

Abstract

The invention relates to a limiting device for a spring type guide track, belongs to the field of guide track limiting devices, and solves the problems that an existing limiting device is complicatedin structure and large in size, and thus, it is difficult to mount products on a guide track rapidly and difficult to separate the same from the guide track reliably. The limiting device comprises a limiting block, a pressure block and a rotating shaft, wherein the limiting block is a hollow cylinder; the pressure block is provided with a through hole of which the cross section is T-shaped; the T-shaped through hole comprises a first through hole with a first diameter and a second through hole with a second diameter; the first diameter is greater than the second diameter; the limiting block isplaced in the first through hole, and the diameter of the limiting block is greater than the second diameter; the rotating shaft can penetrate through the limiting block and the second through hole;the pressure block and a box which supports the guide track are fixed by the two ends of the rotating shaft through fixing assemblies separately; an annular space is formed by the rotating shaft and the inner wall of the limiting block; and a compression spring which can pop up the limiting block is arranged in the annular space. By the limiting device which is simple in structure and small in size, the products on the guide tracks can be rapidly mounted and reliably separated.

Description

technical field [0001] The invention relates to the technical field of guide rail limiting devices, in particular to a limiting device for spring-type guide rails. Background technique [0002] The guide rail limit device is a commonly used accessory in the mechanical field, which is used to limit and fix products on the guide rail. [0003] Existing limiting devices or stoppers generally can only be used to directly fix products on the guide rail, and cannot realize fast installation and reliable separation of the limit, that is, it is difficult to realize rapid installation and reliable separation of products on the guide rail. In addition, the currently existing limit devices for spring-type guide rails are generally fixed and locked to realize the ejection and reset of the pressure block, but the operation is complicated, the reliability is poor, and the structure is complex and bulky. In some special occasions, Due to limited space, the application of this type of stop...
