[ technical field ] A method for producing a semiconductor device

The invention relates to the technical field of universal wheels, in particular to a high-wear-resistance pressure-resistant silent universal wheel.

[ background of the invention ]

Its connecting rod of universal wheel or spliced pole that have now on the market are usually locked and are died on the support, cause wearing and tearing can't change after using longer a period, lead to use cost higher to because the support of universal wheel and the structure of gyro wheel set up unreasonablely, make the gyro wheel can cause great noise at the roll in-process, bring not good experience for the user.

[ summary of the invention ]

In order to overcome the above problems, a universal wheel having high wear resistance, high pressure resistance and noise reduction and silencing effects has been developed.

In order to achieve the purpose, the invention adopts the technical scheme that: a high-wear-resistance pressure-resistant silent universal wheel comprises a support, wherein the support is arc-shaped, a connecting seat is arranged at the top of the support, and a connecting rod is detachably mounted on the connecting seat; the bracket is of a double-layer plate structure, and a sound insulation layer is arranged between the double-layer plates; the bottom of support is installed the gyro wheel, the gyro wheel surface is equipped with compressive layer and wearing layer in proper order.

In one or more embodiments, the connecting seat is provided with a threaded cavity, and the bottom side of the connecting rod is provided with a threaded portion and is in threaded connection with the threaded cavity.

In one or more embodiments, the double-layer plate structure of the bracket is made of an acoustic baffle material.

In one or more embodiments, the sound-insulating layer is butyl damping rubber.

In one or more embodiments, the compression resistant layer is made of polytetrafluoroethylene.

In one or more embodiments, the wear layer is made of chlorosulfonated polyethylene rubber, urethane rubber, or hydrogenated nitrile rubber.

Compared with the background technology, the invention has the following beneficial effects:

by adopting the technical scheme, the universal wheel is provided with the detachable connecting rod, and can be replaced after being worn for a long time; the support adopts a multi-layer sound insulation plate structure, and sound insulation layers are arranged among the multi-layer sound insulation plates, so that a good silencing effect is achieved; the surface at the gyro wheel is equipped with compressive layer and wearing layer, has improved the crushing resistance and the wearability of gyro wheel greatly, has further promoted life.
