Spring buffer

Abstract

The invention relates to a spring buffer. The spring buffer comprises a bottom plate, a top plate, a plurality of springs, and a pair of supporting rods, wherein the bottom plate and the top plate are arranged in parallel; the springs and the supporting rods are arranged between the top plate and the bottom plate; the supporting rods are arranged at two ends of each of the springs; the supporting rods are respectively arranged at two ends of the bottom plate and the top plate. Each of the supporting rods comprises a rod piece A and a rod piece B which are arranged in the same vertical line, wherein each rod piece A is in the shape of a hollow cylinder, an upper end of each rod piece A is fixed on the top plate, a lower end of each rod piece A is arranged in a dangling manner, and a pair of vertical through slots symmetrically formed forward and backward is formed in the lateral walls of the lower end of each rod piece A. Each rod piece B is in the shape of a cylinder, a pair of lugs which is matched with the vertical through slots in an embedded manner is arranged on the top of each rod piece B; an upper end of each rod piece B is inserted into a cavity at the middle part of each rod piece A in a sleeving and matching manner; a lower end of each rod piece B is fixed on the bottom plate. The spring buffer disclosed by the invention has the advantages that the spring buffer consists of the springs and the supporting rods, the lugs move up and down in sliding slots under the action of the vibration of the springs, and the spring buffer is reasonable in structural arrangement; besides, the springs can be mounted once, so that the spring buffer is simple and convenient to mount.

Description

technical field [0001] The invention relates to a buffer, in particular to a spring buffer. Background technique [0002] Spring buffer is a buffer device used in machinery and other fields, mainly used to slow down the speed, improve safety and comfort. [0003] The traditional spring shock absorber uses a single spring to be inserted and sleeved on a column. If a single spring is used to work, the center of gravity will be unstable and the working stability will be poor; if multiple spring shock absorbers are used, due to the differences in each structure, the work will be stable. Performance will also be poor, and multiple installations are extremely inconvenient simultaneously, therefore be badly in need of developing a kind of spring bumper with good working stability, simple and convenient installation, through retrieval, do not find identical or similar technical scheme with the present invention. Contents of the invention [0004] The technical problem to be solve...

Problems solved by technology

[0003] The traditional spring shock absorber uses a single spring to be inserted and sleeved on a column. If a single spring is used to work, the center of gravity will be unstable and the working stability will be poor; if multiple spring shock absorbers are used, due to the differences in each structure, the work will be stable. The performance will also be poor, and multiple installations are extremely inconvenient. Therefore, it is urgent to develop a spring buffer with good working stability and simple and convenient installation. After searching, no technical solution identical or similar to the present invention has been found.
