Vibration reduction type trundle

Abstract

The invention relates to the technical field of trundles, and particularly relates to a vibration reduction type trundle which comprises a trundle support, a wheel installed on the lower portion of the trundle support and a mounting structure arranged on the upper portion of the trundle support and used for being connected with bearing equipment, the trundle support comprises a support body, a vibration reduction frame, a fixing frame, at least one set of spring and a fixing rod, and the vibration reduction frame is of an integrally-formed structure; according to the vibration reduction type trundle, a lever principle vibration reduction mechanism is formed by matching the support body, the vibration reduction frame and the spring and the vibration reduction effect is better; and the pressing plate on the vibration reduction frame downwards abuts against the upper end of the spring, the structural strength is high, the force bearing performance is good, the stability and the durabilityare better, the occupied space of the structural design in the longitudinal space is small, the longitudinal swing space of the vibration reduction frame is large, the bearing piece is connected to the lower end of the fixing rod in a threaded mode, and disassembly and assembly are convenient.

Description

Technical field [0001] The invention relates to the technical field of casters, in particular to a vibration-damping caster. Background technique [0002] Casters are a common mechanical hardware accessory. They are widely used on the bottom of load-bearing equipment (such as furniture, carts, machining equipment, and medical equipment) to facilitate the movement of the load-bearing equipment. On the ground, greater vibration will occur, which will not only affect the load-bearing equipment and the experience of use, but also affect the life of the casters. At present, some existing casters also have the function of damping, but generally they are directly loaded and damped by springs. This damping method has a poor damping effect, and because the spring directly bears the weight, the requirements for the spring are higher. Moreover, the loss of the spring is also large, and the damping function is prone to failure. Summary of the invention [0003] In order to overcome the defe...

[0002] Caster is a common mechanical hardware accessory, which is widely used on the bottom of carrying equipment (such as furniture, carts, machining equipment, medical equipment) to facilitate the movement of carrying equipment. When the ground is on the ground, there will be a large vibration, which will not only affect the carrying equipment and user experience, but also affect the life of the casters

At present, some existing casters also have the function of damping vibration, but generally the load is directly loaded by the spring and the vibration is damped. Moreover, the loss of the spring is also large, and the vibration damping function is prone to failure.
