Description

A kind of universal seclector

Technical field

The utility model is related to technical field of electric appliances, and in particular to a kind of universal seclector.

Background technology

Universal seclector can be just that the household electrical appliance of different electric currents are converted under the voltage and current that it can be used Normal work.Universal seclector is by the multiloop control apparatus of multigroup mutually isostructural contact assembly closed assembly.Existing city Universal seclector on face can be divided into two kinds of self-resetting type and self-localization-type by the mode of operation of handle, be illustrated in fig. 1 shown below, but all Can only realize connecting another contact again after first disconnecting a contact during this handover operation of every grade of operation handle, it is impossible to realize Another disconnects closure again after one closing of contact.

The content of the invention

In order to solve the above technical problems, the purpose of this utility model there are provided a kind of universal seclector, to solve The defects such as existing capability is single, poor practicability.

To achieve the above object, a kind of universal seclector of the utility model, it includes that pedestal, fixation are interspersed in pedestal On rotating shaft and cam pack, described rotating shaft one end is provided with knob, the rotating shaft engagement connection sprocket drive spindle, the cam pack Including contact supporting, touch spring, two contacts and cam set jaggy is set, described two contacts include contact A and contact B, the cam set includes cam A and cam B, and angle is 60 ° between the breach of the cam A and cam B, the cam A and convex Wheel B superposition engagements are connected on the gear shaft, and not in same level, the contact A coordinates for the contact A and contact B Contact cam A outer rims, contact B coordinates contact cam B outer rims.

Further, described pedestal is provided with 0,1,2 three gears.

Further, described touch spring is arranged on the rear end of the contact A and contact B.

Further, described cam A and cam B is integrated.

Compared with prior art, its advantage is the utility model：A kind of universal seclector of the present utility model, adopts Cam set is formed with individual layer two panels cam replaces the direction of single cam, such cam notch to be just easier adjustment, while When knob is shifted gears and changed, two contacts can produce the state occured simultaneously and close, so after next contact closes completely, A upper contact can just disconnect, it is possible to realize more functions, total the utility model have simple structure, it is multiple functional, Practical advantage.

Specific embodiment

To describe technology contents, structural feature, institute's reached purpose and effect of the utility model in detail, reality is hereby enumerated below Apply example and coordinate accompanying drawing to be explained in detail.

In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear", The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outward " are based on accompanying drawing institute The orientation or position relationship for showing, are for only for ease of description the utility model and simplify description, signified rather than indicating or implying Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality The limitation of novel protected scope.

Refer to shown in Fig. 1, and combine shown in Fig. 2 and Fig. 3, the utility model provides a kind of universal seclector, and it is wrapped Pedestal 1, fixed rotating shaft 2 and the cam pack being interspersed on pedestal 1 are included, the one end of the rotating shaft 2 is provided with knob 3, and the rotating shaft 2 is nibbled Connection sprocket drive spindle 4 is closed, the cam pack includes contact supporting 5,6, two contacts of touch spring and is provided with the cam of breach 9 Group, described two contacts include contact A7 and contact B8, and the cam set includes cam A10 and cam B11, the cam A10 Angle is 60 ° and between the breach of cam B11, and the cam A10 and cam B11 superposition engagements are connected on the gear shaft 4, institute Contact A7 and contact B8 are stated not in same level, the contact A7 coordinates contact cam A10 outer rims, contact B8 coordinates contact Cam B11 outer rims.

Further, described pedestal 1 is provided with 0,1,2 three gears.

Further, described touch spring 6 is arranged on the rear end of the contact A7 and contact B8.

Further, described cam A10 and cam B11 is integrated.

As shown in figure 4, now switch position is located at 0 grade, contact A therein is in closure state, and contact B is in and disconnects shape State, 0-1 grades of centre position is turned to by knob rotating shaft drive cam set, when with 0 grade and 1 grade into 30 ° of angles, As shown in figure 5, now contact A and contact B are in closure state, subsequent turning knob to 1 file location, as shown in fig. 6, now Contact A belongs to off-state, and contact B belongs to closure state, completes once complete gear shift operation, this ensures that theres under After one contact closes completely, a upper contact can just disconnect, it is possible to realize more functions, total the utility model tool There is simple structure, multiple functional, practical.

In sum, the only preferred embodiment of the utility model, does not limit protection domain of the present utility model with this, all The equivalence changes made according to the utility model the scope of the claims and description and modification, are all what the utility model patent covered Within the scope of.
