Cushioning wheel structure of travel suitcase

Abstract

The invention discloses a cushioning wheel structure of a travel suitcase, which comprises a castor base, a castor, a linkage rod and an elastic pressure bearing component. The castor base is fixed on a suitcase body of the travel suitcase, the castor is fixed at one end of the linkage rod via an axle, the other end of the linkage rod is hinged on the castor base, the middle of the linkage rod is fixedly connected onto the castor base via the elastic pressure bearing component, and the elasticity direction of the elastic pressure bearing component is opposite to a rotating direction of the linkage rod rotating around a hinging end. The cushioning wheel structure can effectively absorb impact force of the external, simultaneously is simple in structure, compact in mutual match and high in reliability, is durable, and is not easy to be damaged even if the cushioning wheel structure runs on a rough road surface for a long time.

Description

technical field [0001] The invention relates to accessories of suitcases, in particular to a shock-absorbing wheel structure of suitcases. Background technique [0002] Nowadays, there are various suitcases on the market, and the appearance of these suitcases provides great convenience for people to carry personal belongings when they go out.

People add tugboats at the bottom of the suitcase, and the user can drag the suitcase, which greatly reduces the burden when going out, makes walking more convenient and easier, and saves a lot of physical strength. If you encounter uneven ground conditions such as unevenness or some small pits and depressions, dragging the suitcase will increase the collision between the casters and the ground, and the weight of the suitcase will cause the suitcase to walk unstable. Even the case of broken casters. The anti-vib...

Problems solved by technology

If you encounter uneven ground conditions such as unevenness or some small pits and depressions, dragging the suitcase will increase the collision between the casters and the ground, and the weight of the suitcase will cause the suitcase to walk unstable. Even the case where the casters break

The anti-vibration structure of the existing casters is relatively complicated. When used for a long time or subjected to a large impact, the caster structure is easily damaged or displaced, causing the casters to be stuck or fall off, thereby reducing the reliability of the luggage.
