Strong-impact-resistant back shock absorber

Abstract

The invention provides a strong-impact-resistant back shock absorber, which comprises a shell, a center shaft, damping parts and a bearing joint, wherein the upper end and the lower end of the shell are each provided with a round shock absorption cavity for containing the damping parts; the damping parts are arranged in the shock absorption cavities; the two ends of the center shaft extend into the shock absorption cavities to be connected with the damping parts, and the bearing joint is connected to the center shaft and can slide along the center shaft and rotate around the center shaft; each of the damping parts comprises a quick release part, a metal elastic part, an end cover, a friction plate and a conical spring, wherein the quick release part is installed at the end of the center shaft, the metal elastic part is in a gear shape, a gap exists between the metal elastic part and the inner walls of the shock absorption cavities; the end cover is connected to the ends of the shock absorption cavities; the friction plate is hidden in the end cover and makes surface contact with the quick release part; and the conical spring is connected between the end cover and the friction plate in an abutting mode. The gear-shaped metal elastic part is adopted as elastic limiting to cause rigidity gradual change, and the impact amplification phenomenon of a traditional shock absorber is improved.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a back shock absorber with strong impact resistance. Background technique [0002] Modern warfare has been around much since with advanced electronics and electronics. Whether the electronic equipment installed on various means of transportation can work stably and reliably in a complex and changeable environment plays a decisive role in ensuring the victory of the war. [0003] As the key to ship monitoring, the display console must first ensure the reliability in dynamic environments and the ability to withstand harsh environments, and at the same time meet its electrical performance indicators. The display consoles used on ships will inevitably be affected by various shocks and vibrations, as well as electronic equipment during travel or war. Under this influence, the functions of internal components of electronic equipment are damaged or even completely failed. [0004] The shock absorb...

Problems solved by technology

[0005] Most of the current back shock absorbers use cylindrical elastic parts to play a buffering role, but because traditional elastic parts can only play the role of vibration reduction or impact resistance, they cannot take both into account; and the existing back shock absorbers In the structure that adjusts the frictional force by changing the compression of the spring, there are many structural parts and the force-bearing area is small, and the stability is not enough in actual use.
