Buffer mechanism

Abstract

The invention provides a buffer mechanism which comprises a buffer plate and a support plate which are arranged in parallel, and at least one group of buffer units arranged on the support plate so asto solve the technical problems that the service life of a spring buffer in the prior art is short, the structure of the buffer made of a special working medium is complex, and the manufacturing and using cost is high. Each buffer unit comprises a first piston, an elastic piece, a cavity, a second piston and a hook component, wherein the elastic piece is arranged between the buffer plate and the support plate; and the cavity is internally provided with a chamber, the piston part of the first piston is arranged in the chamber, and the shaft rod part is connected with the buffer plate; the second piston is positioned on one side, opposite to the buffer plate, of the first piston, one end, corresponding to the second piston, of the chamber is provided with a communication path for inserting the shaft rod part of the second piston into the chamber, and the communication path is provided with an exhaust hole communicating with the outside. The medium used by the buffer mechanism is air, noadditional medium supply equipment is needed, the structure is simple, and the manufacturing and using cost is low.

Description

technical field [0001] The invention relates to a buffer device for buffering and shock-absorbing movable parts and preventing retreat and re-advancement. Background technique [0002] The buffer mechanism refers to the mechanism that acts as a buffer and shock absorber for moving parts through energy conversion, and prevents retreat and re-advancement. The earliest buffering mechanism used the elastic force of the spring to decelerate and push back the object. This kind of buffering mechanism has a simple structure and is widely used in products that require buffering and shock absorption. The service life of the spring is determined by the material used to make the spring, whether the spring design is reasonable, the use environment of the spring, the working form of the spring, etc. If the spring has been in working condition since it is installed, the spring life of this special working form is generally longer. low and needs to be replaced periodically. Later, a gas...

Problems solved by technology

Later, a gas buffer with gunpowder gas as a working medium and a liquid buffer with a liquid (such as kerosene) as a working medium appeared. These two buffers need to be equipped with a medium supply mechanism, and the structure is relatively complicated. Will produce environmental and product pollution
