Embodiment Construction
[0015] Such as Figure 1-2 As shown, a conductive wheel includes a wheel body, the wheel body is composed of an insulating plastic inner lining 2 and a plastic outer lining 1 wrapped outside the insulating plastic inner lining 2, and the inner plastic outer lining 1 is provided with conductive masterbatches And the elastic element 3, the middle part of the insulating plastic lining 2 is embedded with a bearing conductor 4.
[0016] In this embodiment, the insulating plastic inner lining 2 is provided with a groove 21 connecting the through-bearing conductor 4 and the plastic outer lining 1 .
[0017] In this embodiment, the elastic element 3 is arranged in the groove 21, and the elastic element 3 can effectively prevent the shrinkage of the plastic during cooling, so that the plastic lining material in the groove is separated from the surface of the bearing conductor.
[0018] In this embodiment, the manufacturing method of the conductive wheel is as follows. First, the beari...

The invention relates to an electric conduction wheel. The electric conduction wheel comprises a wheel body, wherein the wheel body consists of an insulated plastic cement inner lining and a plastic outer lining wrapping the outer part of the insulated plastic cement inner lining; an electric conduction master batch and an elastic element are arranged in the plastic outer lining; a bearing conductor is inlaid in the middle part of the insulated plastic cement inner lining; a groove which enables the bearing conductor and the plastic cement outer lining to be connected in a penetrating manner is formed in the insulated plastic cement inner lining; the elastic element is arranged in the groove. The manufacturing method of the electric conduction wheel comprises the following steps of firsly performing integral injection-molding on the bearing conductor as a ridge member and the insulation plastic cement so as to form the insulated plastic cement inner lining, then plugging the elastic element in the groove in the insulated plastic cement inner lining, and finally performing secondary injection-molding on the assembled member as the ridge member and plastic with the electric conduction master batch so as to form the plastic cement outer lining. The electric conduction wheel disclosed by the invention is low in noise, not liable to rust, low in cost, reliable in structure, and diversified in injection-molding models. According to the electric conduction wheel, static electricity concentrated on the bearing conductor can be transferred to the earth surface, so that the static electricity carried on the electric conduction wheel and even the static electricity carried on carriers on the electric conduction wheel can be removed.
Description
technical field [0001] The invention relates to a conductive wheel, in particular to a conductive wheel suitable for removing static electricity on a metal trolley or a bed carrier. Background technique [0002] At present, with the development of society, plastic wheels are widely used, especially hospital beds and carts in the medical industry, which are deeply loved by the industry because of their low noise, not easy to rust, low cost, reliable structure, and various shapes. However, due to the high load and high strength requirements of large nursing facilities such as hospital beds and trolleys, most of them use metal structures, and air friction and wheel bearing rotation processes will cause them to carry static electricity, leaving potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to provide a plastic material as the main body, which can transfer the static electricity concentrated at the bearing conductor to the ...
