Abstract

The invention relates to a damping trundle, which is characterized by comprising an installation support which is connected with a car body or a box body, a sway stand which is hinged with the installation support and provided with a front supporting plate and a rear supporting plate, a wheel shaft which is installed between the front and the rear supporting plates of the sway stand, a trundle which is installed on the wheel shaft and a damping device which is installed between the tail part of the sway stand and the installation support, when the trundle collides an obstacle, the trundle and the front part of the sway stand collectively move upwards, and the sway stand can move downwards to the tail part by adopting the hinge part of the sway stand and the installation support as a supporting point and acts on the damping device so as to realize the damping function. The damping trundle is simple in structure and capable of realizing the damping function and greatly improving the service life of the trundle.

Description

Technical field: [0001] The invention relates to a shock-absorbing caster. Background technique: [0002] Existing casters generally only include a mounting bracket that can be connected to a car body or a box body, a wheel shaft that is located on the mounting bracket, and a caster wheel that is installed on the wheel shaft. Because the existing casters have no damping device, when the casters pass through the uneven ground, they cannot play a shock-absorbing effect, and the service life of the casters will be greatly shortened. Invention content: [0003] The object of the present invention is to provide a shock-absorbing caster, which has a simple structure, can realize the shock-absorbing function, and can improve the service life of the caster. [0004] A shock-absorbing caster, characterized in that: it includes a mounting bracket that can be connected with a car body or a box body, a swing frame with a front support plate and a rear support plate pivotally connecte...
