Folding caster and heater

Abstract

The invention provides a folding caster. The folding caster comprises a base and at least one caster assembly, wherein the caster assemblies are rotatably mounted on the base between an unfolding position and a folding position; the folding caster further comprises a pressing plate arranged on the base; and the caster assemblies are matched with the pressing plate in the unfolding position and thefolding position correspondingly to limit the rotating angles of the caster assemblies. Compared with the prior art, the folding caster provided by the invention has the advantages of being simple and durable in structure, high in stability, convenient to store and package, small in number of parts, capable of saving the packaging space and convenient to transport.

Description

Technical field [0001] The invention relates to the field of casters, in particular to a folding caster and a heater. Background technique [0002] Generally, the overall length of the caster parts of the product is greater than the width of the product body, which is likely to cause difficulty in packing and transportation. In order to save packaging space and facilitate product transportation, manufacturers have to disassemble the caster parts and pack them into the packaging box separately. The customer assembles and installs on the product by himself. In this process, the user needs to assemble the caster parts, flip the product body, install the assembled caster parts to the bottom of the product body, turn the product over and other operations, which are labor intensive and time-consuming. Moreover, once parts are lost during this process, it is easy to cause the caster parts to fail to operate normally. For this reason, many manufacturers also try to develop new caster pa...

AI Technical Summary

Problems solved by technology

The technical solution described in this utility model has the following disadvantages: Although the problem of wasteful packaging caused by the length of the casters and the rotating plate is solved, the rotation angle of the rotating plate cannot be effectively controlled, and it is easy to move during transportation and damage parts , and the rotating plate cannot be accommodated in the oil tank, there is still unnecessary waste of packing box space

The technical solution described in this utility model has the following disadvantages: although the rotation angle of the caster assembly is controlled to a certain extent, the caster assembly cannot be accommodated when it is in the folded position, and there is a waste of packing box space; Wear and tear can also affect the stability of the caster assembly in the folded unfolded and folded positions, making it difficult to transport

The technical solution described in this utility model has the following disadvantages: the elastic force of the elastic member decreases after repeated use, which easily causes the caster assembly to be unstable, and there is still the problem that the caster assembly cannot be stored after being folded
