Vibration prevention footstand with alignment structure

Abstract

A vibration prevention footstand with an alignment structure comprises an upper base, a lower base, a sphere and a sliding sleeve. The sphere is arranged in an arc groove formed between the upper base and the lower base and makes point contact with the arc groove to achieve the vibration prevention effect. In addition, due to an inclined plane configured on the upper base and the sliding sleeve, the upper base and the lower base can be easily aligned and centered, and unnecessary correcting time waste is avoided.

Description

technical field [0001] The present invention relates to an anti-shock base, in particular to an anti-shock base with an alignment structure. 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 foot su...

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
