Strong-impact-resistant bottom shock absorber

Abstract

The invention provides a strong-impact-resistant bottom shock absorber. The shock absorber comprises a shell, a center shaft, a damping piece and a spring are arranged in the shell, one end of the center shaft is open and is hollow, the other end of the center shaft penetrates through the top of the shell, and the spring is arranged in the center shaft and used for buffering external impact force. The damping piece is arranged at the lower side of the center shaft and makes contact with the inner wall of the shell. A baffle is arranged at the top of the damping piece, a disc spring is placed on the baffle, a pressing plate is connected to the center shaft and can move up and down along the center shaft to change the deformation quantity of the disc spring, and the damping piece is limited between the baffle and the bottom of the center shaft. When resonance occurs in the shock absorber, friction force generated between the baffle and the damping piece restrains resonance, and the load of the shock absorber can be changed under the condition that the appearance structure is not changed.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to a strong shock-resistant bottom shock absorber. Background technique [0002] Modern warfare relies more on advanced electronic equipment and electronic technology. 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. [0004] Display consoles used on ships are inevitably affected by various shocks, vibrations (regular and irregular), and electronic equipment during travel or wartime. Among various effects, shock and vibration have the greatest impact on electronic equipment: sometimes the functions of ...

Problems solved by technology

[0007] The utility model patent with the notification number CN204512269U provides a non-resonant peak anti-strong impact vibration isolator, which uses friction between the damping friction ring and the upper cone cavity or the lower cone cavity to suppress resonance, and compresses the butterfly spring to facilitate The reset of the damper, but this structure uses many parts, and there are many relative movements between the parts, the damper wears fast, and it is also prone to jamming
