Abstract
The utility model discloses a rotating shaft of an assistant switch, which is divided into a thick shaft (1) and a thin shaft (2). The connection of the thick shaft (1) and the thin shaft (2) is provided with a limiting base (3), the thick shaft (1) and the thin shaft (2) are two shafts and polygon shafts, the cross section of the thick shaft (1) and the thin shaft (2) is of a trilateral figure or a quadrangle or more four figure. One end of the thick shaft (1) is provided with a polygon hole (4) matching with the thin shaft (2). The thin shaft (2) can insert into the polygon hole (4) of the thick shaft (1). The utility model can achieve the automatic operation of the assistant switch, and prevent the rotating shaft from drawing out of the assistant switch or changing the position.
Description
Technical field
The utility model relates to a kind of auxiliary switch inner structural members of (having another name called universal seclector or cam switch), and especially a kind of rotating shaft of electrical equipment auxiliary switch belongs to technical field of electric appliances.
Background technology
Present existing auxiliary switch has two kinds, a kind of metal rotating shaft that is not provided with, as the disclosed universal seclector of China patent of invention specification CN200510039139.8, it directly passes through the spline cam drive of plastic material, its shortcoming is that bad mechanical strength, the transmission of plastic cam is poor and have a time, influence break performance, especially be not suitable for the auxiliary switch of high joint number; Present known another kind of auxiliary switch, as the disclosed universal seclector of China utility model patent specification CN200420032370.5, though be provided with rotating shaft (this patent is defined as camshaft with it), but because set rotating shaft is for waiting thick axle, only be applicable to human control, be not easy to auxiliary switch directly is connected with the operating mechanism of control appliance, can not realize automatic control, and the employing on thick axle can increase the overall volume of auxiliary switch, thereby or makes the cam-wall attenuation easily cause intereelectrode short-circuit.
Summary of the invention
In order to solve the prior art above shortcomings, the utility model proposes a kind of rotating shaft of auxiliary switch, it is made by metal material, be divided into thick axle and thin axle two partly, on the thick axle of thick axle and thin axle junction, be provided with limit base, its thick axle and thin axle are two axles, and be polygon shaft, end at thick axle is provided with the polygonal hole that matches with thin axle, in this polygonal hole that thin axle can insert slightly spool, rigidity of the present utility model and intensity height can dwindle the volume of auxiliary switch, can realize the automatic operation of auxiliary switch, and can prevent that rotating shaft from extracting or scurrying the position in auxiliary switch.
The utility model solves its technical problem, and the technical scheme that is adopted is: a kind of rotating shaft of auxiliary switch, to make by metal material, and its design feature is: rotating shaft is divided into thick axle and thin axle two parts, is provided with limit base on the thick axle of a thick axle and a thin junction.
Above-mentioned thick axle and thin axle are polygon shaft, and the shape of its cross section is triangle or quadrangle or polygon more.
Above-mentioned thick axle and thin axle are two axles, are provided with the polygonal hole that matches with thin axle at an end of thick axle, in this polygonal hole that thin axle can insert slightly spool.
Above-mentioned limit base uses plastic material, and thick axle adopts non-dismountable formula stressed joint with limit base, is provided with the via hole of convenient thin axle plug at the end face of limit base.
Compared with prior art, the beneficial effects of the utility model are: because rotating shaft of the present utility model is a polygon shaft, be divided into thick axle and thin axle two parts, thick axial region part can be inserted the operating mechanism of control appliance and directly is connected with it, its beneficial effect is to realize the automatic manipulation of control appliance to auxiliary switch, be particularly useful for automation control system, thick axial region part receiving control apparatus passes to thin axial region part to the various control actions of auxiliary switch and with it, thin axial region part is inserted in interior each layer cam of auxiliary switch, by cooperating with the corresponding polygonal hole of cam center, each layer cam rotation that drives in the auxiliary switch is switched with the break-make that realizes many circuit.Because the cross-sectional area of thin axle is less, the cross-sectional area of the polygonal hole of cam center with matching is also less, and then can dwindle the overall dimension of cam and auxiliary switch, realizes volume miniaturization, the compact conformationization of auxiliary switch, saves the space.The beneficial effect that limit base is set on the thick axle of thick axle and thin axle junction is to make rotating shaft realize axial accurate limiting in auxiliary switch, and the assurance rotating shaft axial endplay can not take place, and prevents rotating shaft play or deviate from from auxiliary switch in auxiliary switch.

Embodiment
Shown in Fig. 1-4, first kind of embodiment of the present utility model is: a kind of rotating shaft of auxiliary switch, make by metal material, be divided into thick axle 1 and 2 liang of parts of thin axle, on the thick axle 1 of thick axle 1 and thin axle 2 junctions, be provided with limit base 3, in the present embodiment, thick axle 1 and thin axle 2 are two square shafts (being the quadrangle axle), end at thick axle 1 is provided with and thin axle 2 square holes that match 4 (being quadrilateral hole), thin axle 2 can insert in this square hole 4 of thick axle 1, when the auxiliary switch that present embodiment is housed in use, thick axial region part 1 of its rotating shaft can be inserted in the operating mechanism of control appliance and with it and directly is connected, thick axle 1 receiving control apparatus passes to thin axle 2 to the various control actions of auxiliary switch and with it, in each layer cam that thin axle 2 inserts in the auxiliary switch, by cooperating, drive the rotation of each layer cam and switch with the break-make that realizes many circuit with the corresponding square hole of cam center.Limit base 3 uses plastic material and fuses with thick axle 1 method by embedded injection moulding, and both are that non-dismountable formula connects, and are provided with the via hole 5 of convenient carefully axle 2 plugs at the end face of limit base 3.It is cylindrical that the profile of limit base 3 is ladder, and its effect is to make rotating shaft realize axial accurate limiting in auxiliary switch, prevents rotating shaft play or deviate from from auxiliary switch in auxiliary switch.Make by metal material with thin 2 owing to thick axle 1, its rigidity and intensity height, when the auxiliary switch of control more piece number, plastic deformation can not occur, switch, simultaneously because the cross-sectional area of thin axle 2 is less so can realize multiloop while break-make, the cross-sectional area of the square hole of cam center with matching is also less, and then the overall dimension that can dwindle cam and auxiliary switch, volume miniaturization, the compact conformationization of realization auxiliary switch are to save the space.In the present embodiment, on thick 1 outer surface, be provided with through hole 6 away from the square hole end, on the operating mechanism of control appliance, also be provided with and 6 corresponding holes, hole, after thick axle 1 inserts the operating mechanism of control appliance, insert lock pin by hole 6 thick 1 operating mechanism with control appliance linked together, from the operating mechanism of control appliance, deviate to prevent thick axle 1.
