Three-level buffer suitable for achieving even buffering of each level

Abstract

The invention relates to a three-level buffer suitable for achieving even buffering of each level. The three-level buffer comprises a primary level buffer, a middle level buffer and a last level buffer. Each level of buffer comprises a cylinder body of a cylindrical shape, wherein a cylinder cover is arranged at the opening end of each cylinder body in a sealing mode, a piston rod is arranged in a center through hole of each cylinder cover in a sealing movable and matching mode, and the right end of each piston rod is provided with a piston body component which is suitable for conducting piston motion in each cylinder body and is matched with the inner wall of each cylinder body in a movable and sealing mode. The cylinder body of the primary level buffer forms the piston rod of the middle level buffer, the cylinder body of the middle level buffer forms the piston rod of the last level buffer, the right end face of the piston body component of the primary level buffer is provided with a pressure sensor used for detecting medium pressure, and the piston body component of each level of buffer is suitable for adjusting the back-and-forth flow of medium in a corresponding cylinder body and controlling the speed of the piston motion according to the medium pressure detected by the pressure sensor when the piston motion is conducted.

Description

technical field [0001] The invention relates to a buffer, in particular to a buffer using elastic colloid as a buffer medium. Background technique [0002] In the field of cushioning and shock absorption, buffers are widely used, and their main functions are to absorb various impact energy, protect equipment and reduce noise. [0003] The authorization number CN 202149175 discloses a buffer, which is a two-stage buffer, through the difference of the medium maximum force F1max and the initial minimum force F2cmin in the primary buffer and the secondary buffer, to control the primary buffer, secondary buffer The order of action of the first-stage buffer; and it is mentioned in the specification that the capacity of the entire buffer is set according to the impact energy, but in real work, because the impact energy is not constant, there may be changes, so it depends on the medium To realize the working order of buffers at all levels, it is difficult to realize in practice. ...
