Abstract
The utility model relates to an up and down switch main shaft integrated member, comprising a metal rotation shaft, and the metal rotation shaft is fixedly provided with a plastic sleeve component formed by the injection moulding. In the utility model, one plastic sleeve member substitutes the rotation shaft, the pin, the positioning member, the bush, the cam, the plain cushion, the elastic cushion, nuts and other parts of the prior art, the utility model has an integrative main shaft, simple structure, easy manufacture technics and low production cost. In addition, the up and down switch main shaft integrated member has no the problem of the radial direction rotation between the cam and the rotation, improving the abrade-resistant performance, extending the service life of the machinery.
Description
One, affiliated technical field
The utility model relates to a kind of two-direction switch, refers in particular to a kind of spindle assemblies that is used for two-direction switch.
Two, background technology
At present, known two-direction switch mainly is made up of shell, base, moving contact, fixed contact, spindle assemblies, operating mechanism etc. on the market, spindle assemblies is assembled into moving contact, insulating part, standard component etc. and contacts group, and logical and disconnected with the forward and backward that realizes two-direction switch is as KO
3-15,30 type two-direction switchs, HY2-30 two-direction switch etc.As shown in Figure 1, the spindle assemblies that is used for the HY2-30 two-direction switch at present is made up of rotating shaft, pin, keeper, lining, cam, plain cushion, bullet pad, nut etc., the spindle assemblies number of spare parts is more, the structure more complicated, also exist the problem of radially rotating between cam and rotating shaft, because have the problem of radially rotating, product is easy to wear, has influenced the mechanical endurance of product.
Three, utility model content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of two-direction switch integrated spindle axis assembly is provided, and it has characteristics such as number of spare parts is few, simple in structure, wear-resistant, mechanical endurance is long, manufacturing process is simple, production cost is low.
For achieving the above object, the solution that the utility model is taked is: a kind of two-direction switch integrated spindle axis assembly, it comprises metal rotating shaft, is fixed with on metal rotating shaft by injection molded plastics external member.
The utility model is assembled into moving contact, insulating part, standard component etc. and contacts group, logical and disconnected with the forward and backward that realizes two-direction switch.In the utility model, a plastics external member has replaced parts such as rotating shaft of the prior art, pin, keeper, lining, cam, plain cushion, bullet pad, nut, integrated spindle axisization, simple in structure, manufacturing process is simple, production cost is low, and does not have the radially rotational problems between cam and rotating shaft, has improved abrasion resistance properties and has prolonged mechanical endurance.
