A kind of folding caster and heater

Abstract

A folding caster, comprising a base and a caster assembly, the caster assembly is rotatably mounted on the base between an unfolded position and a folded position, the number of the caster assembly is at least one, and also includes a pressure plate, the pressure plate Arranged on the base, the caster assembly cooperates with the pressure plate at the unfolded position and the folded position respectively to limit the rotation angle of the caster assembly. Compared with the prior art, the folding caster provided by the present invention has the following advantages: simple and durable structure, strong stability, convenient storage and packaging, less parts, saving packaging space, and convenient transportation.

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 easily causes difficulties in packing and transportation. In order to save packaging space and facilitate product transportation, the manufacturer has to disassemble the caster parts and pack them into the packing box separately, and then The customer assembles and installs it on the product by itself. During this process, the user needs to assemble the caster parts, turn over the product body, install the assembled caster parts on the bottom of the product body, and turn the product over, which is labor-intensive and time-consuming. Moreover, once parts are lost during this process, it is easy to cause the caster parts to be unable to use normally. For this reason, many manufacturers also try to develop new cast...

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
