Nitrogen cylinder fixing device

Abstract

The invention relates to the technical field of nitrogen cylinders, and discloses a nitrogen cylinder fixing device which comprises a base plate. Two sets of fixing rings and four sets of supporting columns are arranged at the top of the base plate, pressing devices are arranged in the middles of the inner concave faces of the front sides of the two fixing rings, and linkage limiting devices are arranged on the wall faces of the front sides of the two fixing rings. Each linkage limiting device comprises a limiting rod. According to the nitrogen cylinder fixing device, the fixing rings, the pressing devices and the linkage limiting devices are arranged, a nitrogen cylinder is fixedly stored, and a pressing plate is buffered and extruded through the outer wall of the rear side of the nitrogen cylinder, so that the pressing plate extrudes and injects air in a pressing groove cavity into two sets of linkage air bags; the two sets of pressurized linkage air bags extrude and push out the corresponding limiting rods through the sliding plates, finally, the outer wall of the nitrogen cylinder is annularly wrapped and limited through the four corresponding limiting rods in the upper set and the lower set, and the nitrogen cylinder is fixedly limited between the fixing rings and the limiting rods.

Description

technical field [0001] The invention relates to the technical field of nitrogen cylinders, in particular to a nitrogen cylinder fixing device. Background technique [0002] When the nitrogen cylinder is stored, it is generally placed on the bottom plate with a semicircular limit ring. The body of the nitrogen cylinder is limited in the annular groove of the limit ring, and then the chain is used to lock the nitrogen cylinder in the limit ring. The first purpose is to fix the nitrogen cylinder, and the second is to prevent the nitrogen cylinder from tilting or collapsing when it is stored on the bottom plate, so as to facilitate its transfer and transportation. However, the nitrogen bottle fixing device of the prior art is generally designed relatively simple, and often has the following disadvantages in use. First, when the nitrogen bottle is transported after being placed on the upper limit of the bottom plate, the nitrogen bottle is rigidly squeezed against the inner wall ...

Problems solved by technology

However, the nitrogen bottle fixing device of the prior art is generally designed relatively simple, and often has the following disadvantages in use. First, when the nitrogen bottle is transported after being placed on the upper limit of the bottom plate, the nitrogen bottle is rigidly squeezed against the inner wall of the limit ring during transportation. Collision will easily cause damage to the nitrogen cylinder. When the second nitrogen cylinder is fixed in the limit ring, the fixing efficiency is low, and it is impossible to perform tight ring contact limit around the nitrogen cylinder. At the same time, the nitrogen cylinder needs to be buffered and protected. Finally, in the existing technology, after the chains at both ends of the front side wall of the limiting ring lock the nitrogen cylinder, the chain cannot directly lock the nitrogen cylinder, and can only limit the nitrogen cylinder, which is likely to cause nitrogen The bottle shakes or even tilts on the bottom plate
