Anti-vibration foot seat with locking device

Abstract

Disclosed is an anti-vibration foot seat with a locking device. The foot seat comprises an upper base, a lower base, a ball and a connecting part, wherein the ball is arranged in arc-shaped grooves formed in the middle of the upper base and the lower base and the arc-shaped grooves are in point contact with the ball, and the anti-vibration effect is formed. When the foot seat is arranged under equipment, the foot seat is fixedly locked under the equipment by means of the connecting part and prevented from moving freely, and the equipment can be more safely and stably placed.

Description

technical field [0001] The invention relates to an anti-vibration foot, in particular to an anti-vibration foot that can be locked under equipment. Background technique [0002] In today's technologically advanced society, there are many sophisticated equipment, ranging from semiconductor manufacturing equipment to common household equipment. And because it is a sophisticated equipment, it needs to provide a certain degree of protection measures, so shock resistance has become one of the most important protection measures. [0003] There are many sources of equipment vibration, including: the vibration of the equipment itself during operation, the vibration caused by the environment, man-made vibration, natural vibration (earthquake), etc. The general shockproof is solved by the contact surface between the equipment and the ground. [0004] The previous technology of Taiwan's new specification 106223 "Anti-seismic feet for audio-visual equipment" discloses an anti-seismic ...

AI Technical Summary

Problems solved by technology

[0005] However, there are several deficiencies in the prior art. First: Since the upper seat 900 and the lower seat 910 are only connected by the point contact of the steel ball 930, when the anti-seismic feet are installed, the upper seat 900 and the lower seat 910 are easy to shift and cannot be fixed. , it is easy to cause skew during installation, and it is very troublesome to install the anti-seismic feet on the four corners of the equipment; second: when the installation is completed in the previous technology, it is difficult to judge and check whether the steel ball 930 is in the center position; third: The curvature of the groove 920 is only slightly larger than that of the steel ball 930. When a shock with a large amplitude like an earthquake occurs, it cannot effectively prevent the shock. Fourth: When the anti-seismic feet are installed on the four corners of the equipment, the height will often be caused by a slight error on the ground. Different, in the case of no height adjustment function, it will also cause uneven force on the anti-seismic feet and affect the shock-absorbing function
