Description

Technical Field

[0001] The utility model relates to the field of vacuum pump auxiliary equipment, in particular to a shock absorbing mechanism for a vacuum pump. Background Art

[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical or physicochemical methods to evacuate the container to obtain a vacuum. The vacuum pump is one of the basic equipment used to evacuate gas from a sealed container. It can act alone or as a pre-pump, maintenance pump, or pre-pump for a booster pump, diffusion pump, molecular pump, etc. It can be used in the manufacture of electric vacuum devices, thermos bottles, vacuum welding, printing, blistering, refrigeration equipment repair, and instrumentation. Because it has the advantages of small size, light weight, and low noise, it is more suitable for use in laboratories. During the use of the vacuum pump, a shock absorbing mechanism will be used for shock absorption.

[0003] A vacuum pump shock-absorbing base is disclosed in a Chinese patent, and its patent number is CN218325166U. In the vacuum pump shock-absorbing base of the patent, the vacuum pump shock-absorbing base includes a bottom plate and a linkage assembly; a support seat is provided on the bottom plate, and a number of evenly distributed shock-absorbing springs are provided inside the support seat, and the linkage assembly includes a compressed air bag, and the compressed air bag is located at the center of the bottom of the support seat. The outer wall of the compressed air bag is provided with a linked air inlet pipe, and the outer wall of the compressed air bag is connected to the inside of the air guide plate through a conduit, and a number of connected and evenly distributed exhaust pipes are provided on the outer wall of the air guide plate. A vacuum pump shock-absorbing base provides a vacuum pump shock-absorbing base, and the compressed air bag in the linkage assembly can absorb the vibration force while increasing the air circulation outside the vacuum pump body by blowing air to the outside of the vacuum pump body, thereby improving the heat dissipation effect of the outside of the vacuum pump body, and thus making the use effect of the shock-absorbing base more outstanding.

[0004] The above-mentioned published patents have the following disadvantages:

[0005] (1) During operation, the vacuum pump will vibrate in all directions due to suction, but the shock absorbing effect of the shock absorbing mechanism in the prior art is limited, which affects the shock absorbing effect of the vacuum pump.

[0006] (2) In the prior art, the shock absorbing mechanism generally adopts a plurality of shock absorbing springs that cooperate with each other to perform shock absorbing operation on the vacuum pump through the elastic force of the springs. However, after long-term use, the springs will rust on their surface or their elasticity will deteriorate, which will affect the shock absorbing effect of the shock absorbing mechanism.

[0007] (3) In the prior art, since different vacuum pumps have different models and sizes, the number of vacuum pumps that can be fixed by the shock absorbing mechanism is limited. After the vacuum pump is fixed, the vacuum pump will shake above the shock absorbing mechanism, causing collision and damage to the surface. Utility Model Content
