Abstract

The invention discloses a shockproof gravity trundle, and aims to provide a shockproof gravity trundle capable of automatically playing a shockproof role. The shockproof gravity trundle comprises a flat plate, a fixing frame and a wheel body, two first rolling bearings are installed on the wheel body, the first rolling bearings are arranged on the left outer side face and the right outer side faceof the wheel body respectively and provided with rolling rods, the rolling rods are communicated with the wheel body, the two ends of each rolling rod are connected with the two first rolling bearings respectively, and the flat plate and the first rolling bearings are connected with the fixing frame. A plurality of idler wheels are arranged on the outer side face of the wheel body, second rollingbearings are installed on the idler wheels, first springs are installed on the second rolling bearings, and the first springs are connected with the rolling rods. The shockproof gravity trundle has the beneficial effects that the first springs, the second rolling bearings and the idler wheels can achieve the purpose of automatically achieving the shockproof effect; the compressed springs play a role in bearing gravity and buffering; a generator, a single-chip microcomputer I, a loudspeaker, a spring I and a spring II prompt whether to be in a working state or not; and a pedal, a brake pad anda motor play a role in braking.

Description

technical field [0001] The invention relates to the technical field of casters, in particular to a shockproof gravity caster. Background technique [0002] Casters are widely used, almost all walks of life are inseparable from casters, casters can be installed on the bottom of various objects for easy movement, such as hospital beds, equipment, suitcases, carts, cabinets and other objects The bottom of the caster, but the structure of the existing casters is relatively traditional. During use, especially on the uneven surface, the installed object will jump due to the lack of a good shockproof design on the uneven place, not only to the installation The structure of the object has an adverse effect, and it can also make the objects to be transported by the installed object have a probability of falling and being lost, which is very inconvenient. Contents of the invention [0003] The present invention aims at overcoming the disadvantage that the casters in the prior art d...
