Abstract

The invention relates to a magnetic force shock-absorbing device. In the prior art, a cylinder type shock absorber requires sealing, and induces leakage and pollution. The technical scheme of the invention applies the phenomenon, electromagnetic induction due to magnetic field variation generates eddy current and magnetic field generated by the eddy current always hinders such relative movement, to the magnetic force shock-absorbing device. The device comprises a bar magnet seat, a bar magnet, a guard tube, an induction tube, media, an induction tube seat, a bottom plate, a bolt a, a panel, abolt b, a locating ring, a spring, a bearing surface, an adjusting bolt and a workpiece requiring shock absorption. The device has the advantageous effects that magnetic force shock absorption methodis adopted so that the problem, the cylinder type shock absorber in the prior art has the disadvantages of leakage and pollution, is solved basically; and the amplitude is effectively diminished, frequency is lowered, and the effective shock absorption effect can be reached.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a structure of a shock absorber using magnetic technology. Background technique [0002] In the traditional spring-shock-absorbing cylinder-type shock-absorbing design, the spring plays the role of supporting the weight of the workpiece, maintaining the horizontal position of the workpiece, ensuring that the workpiece is free from rigid impact, and eliminating vibration. The barrel shock absorber is used to suppress the shock when the spring rebounds after absorbing shock and absorb the energy of external impact. The ideal situation is to use the shock absorber to limit the bounce of the spring to one time. The resistance of the shock absorber can be divided into two parts: compression and rebound, and the rebound resistance occurs during the rebound stroke of the spring after being compressed by an external impact. This is the biggest reason for the existence of the shock absorber. It is us...
