Embodiment 1

[0029] combine figure 1 , figure 2 and image 3 , a multi-cavity recoil damping device of the present embodiment includes a base 1, a damping mechanism 2 and an impact block 3, the base 1 is an installation base, and fixed ear seats 101 can be arranged on both sides of the base 1, It is used to install the base 1, and in actual application, the base 1 may be a separately provided fixed base or other equipment bodies. A chute is provided on the base 1. In this embodiment, the chute is a dovetail-shaped chute. The impact block 3 is provided with a corresponding protruding structure. The protruding structure cooperates with the dovetail-shaped chute to make the impact block 3 slide. Connected to the base 1, the impact block 3 can slide up and down along the chute. The shock absorbing mechanism 2 in this embodiment is mainly composed of a cylinder body and a compression mechanism. The cylinder body is fixedly connected to the base 1, and the compression mechanism is fixedly co...

Embodiment 2

[0039] combine Figure 4 , a multi-cavity recoil damping device of this embodiment, its basic structure is the same as that of Embodiment 1, the difference is that: the outer wall 204 of the cylinder in this embodiment is oval, the slide on the base 1 The slot is a rectangular chute.

Embodiment 3

[0041] The basic structure of the multi-cavity recoil damping device of this embodiment is the same as that of Embodiment 1, the difference is that the base 1 in this embodiment is a cylindrical structure, and the outer wall 204 of the cylinder is circular structure. According to actual needs, the base 1 and the outer wall 204 of the cylinder can be provided as an integral structure.

[0042] The anti-impact damping device of the present invention changes the direction of the impact force through the recoil piston chamber 209, and acts on the top cap 201 through the recoil piston rod 206 to cancel the impact energy and reduce the impact directly on the cylinder body. The impact force is beneficial to the maintenance of infrastructure, and the shock absorption effect is good, and the impact resistance is strong, which can significantly reduce the impact of large loads.

Abstract

The invention discloses a multi-cavity recoiling shock absorption device and belongs to the field of shock absorption devices. The multi-cavity recoiling shock absorption device comprises a substrate, a shock absorption mechanism and an impact block, and the impact block is connected with the substrate in a sliding mode; the shock absorption mechanism is mainly composed of a cylinder body and a compression mechanism, the cylinder body is divided into a main piston cavity and recoiling piston cavities by the symmetrically arranged inner walls of the cylinder body, and the recoiling piston cavities are distributed at two sides of the main piston cavity; a main piston rod arranged on the top cap of the compression mechanism is in clearance fit with the outer wall of the main piston cavity; recoiling piston rods are in clearance fit with the outer walls of the recoiling piston cavities, round holes along the length direction of the recoiling piston rods are opened in the middle upper parts of the recoiling piston rods, one ends of recoiling springs are inserted in the corresponding round holes, and the other ends of the recoiling springs sleeve corresponding spring pressure rods; the substrate is firmly connected with the cylinder body through the outer wall of the cylinder body, and the impact block is firmly connected with the compression mechanism through the top cap. The multi-cavity recoiling shock absorption device is capable of returning and counteracting the impact force, the flexible energy absorption can resist the impact force, the impact on the cylinder body is reduced, and the shock absorption effect is good.

Description

technical field [0001] The invention relates to the technical field of shock absorbing devices, and more specifically relates to a multi-cavity recoil shock absorbing device. Background technique [0002] Different types of impact force will be encountered in different fields. When dealing with these impact forces, elastic materials are usually used to block or use buffer energy-absorbing devices to consume the impact force, so as to reduce the damage caused by the impact force to objects. However, the current impact The force is still more harmful to the object. Among the research topics of scientific and technical personnel, anti-impact shock absorption has gradually been paid attention to. The so-called anti-impact shock absorption refers to transforming the impact force into anti-impact force, and then to resist the impact force and reduce the harm of the impact force to objects, but this technology is not yet mature and has not been widely used. Therefore, how to reduc...
