Abstract

The utility model relates to a knob switch, which comprises a switch main body and a knob, wherein the switch body is extended out of a turning rod. The knob is sheathed on the turning rod, and a switch of the switch body can be controlled by rotating the turning rod. A hole which is matched with the turning rod is arranged on the turning rod, and a cambered elastic sheet which is used for leading in the turning rod is arranged in the hole. A cambered section of the cambered elastic sheet is arranged in the hole, and a lead-in section is extended out of the hole and is outwards inclined and bent. Under the lead-in action of the cambered elastic sheet, the turning rod can be conveniently aligned to the hole of the knob and smoothly enters the hole. Thus the utility model has the advantages of easy alignment and easy and convenient installation.

Description

Rotary switch

Technical field

The utility model relates to rotary switch, particularly relates to a kind of rotary switch that can be applicable to agitating device for kitchen use.

Background technology

Existing rotary switch, the rotary switch especially for agitating device for kitchen use (for example mixer, juice extractor etc.) generally includes switch main body and knob.Described switch main body is installed in the casing of agitating device, and extends outward swing arm.Described knob is offered porose, and match with described swing arm in described hole, thereby described knob sleeve is located on the described swing arm, and can drive the Kai Heguan that described swing arm is controlled described switch main body by rotating described knob.Yet the cooperation in the swing arm of this rotary switch and the hole of knob is all compared closely usually, thereby when assembling, is difficult to swing arm is aimed at the hole, thereby has brought the difficulty of assembling, assembles very inconvenient.

The utility model content

The technical problems to be solved in the utility model is, provide a kind of assembling easily, rotary switch easily.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of rotary switch is provided, comprise switch main body and knob, described switch main body extends swing arm, but described knob sleeve is located on the described swing arm, and the described swing arm of turn and control the switch of described switch main body; Be provided with the arc spring lamination that imports described swing arm in the hole of offering on the described knob with described swing arm cooperates; The segmental arc of described shell fragment is located in the described hole, and its introduction segment stretches out described hole, and outward-dipping bending.

The cross section of the above-mentioned described swing arm of rotary switch is semicircle; The hole of described knob comprises the semicircle main body that cooperates with described semicircle swing arm, and is communicated with draw-in groove that offer, that hold the segmental arc that tightens described spring leaf above described semicircle main body.Perhaps, the cross section of described swing arm is square; The hole of described knob comprises the square main body that cooperates with described square swing arm, and is communicated with draw-in groove that offer, that hold the segmental arc that tightens described spring leaf above described square main body.

The described shell fragment of above-mentioned rotary switch is a metal clips.

Be provided with the switch panel that is used to block described switch main body between described switch main body of above-mentioned rotary switch and the described knob.

Compared with prior art, the swing arm of the switch main body of rotary switch of the present utility model imports by the arc spring lamination that is provided with in the hole of knob, thereby makes things convenient for swing arm to enter into smoothly in the hole of knob, has contraposition advantage easy, easy for installation.

Embodiment

Below in conjunction with accompanying drawing switch of the present utility model is described in further detail.

As shown in Figure 1, be the cross-sectional schematic of the rotary switch of assembling of the present utility model.Described rotary switch comprises switch main body 11 and the knob 12 that matches.Described switch main body 11 extends outward swing arm 13, and described knob 12 offer corresponding to the position of described swing arm 13 porose 14, thereby but described knob 12 is set on the described swing arm 13, and the described swing arm 13 of turn and control the switch of described switch main body 11.Can aim at described hole 14 easily for the ease of described swing arm 13, be provided with the arc spring lamination 15 that imports described swing arm 13 in the hole 14 of described knob 12, described arc spring lamination 15 can be sheet metal, sheet etc.The segmental arc 151 of described shell fragment 15 is located in the described hole 14; And its introduction segment 152 stretches out described hole 14, and outward-dipping bending, thereby under described introduction segment 152 guiding, described swing arm 13 can be aimed at described hole 14 easily, and enters in the described hole 14.

In the present embodiment, the cross section of described swing arm 13 is semicircle; The hole 14 of described knob 12 comprises the semicircle main body 141 that cooperates with described semicircle swing arm 13, and is communicated with draw-in groove 142 that offer, that hold the segmental arc 151 that tightens described spring leaf above described semicircle main body 141, as shown in Figure 2.Segmental arc 151 inlay cards of described shell fragment 15 are in described draw-in groove 142, in the time of in described swing arm 13 enters into described hole 14, described swing arm 13 roof pressures make the segmental arc 151 of described shell fragment 15 produce elastic deformation and compress described swing arm 13, make described swing arm 13 closely cooperate with described knob 12.And when dismounting, only need firmly extract described knob 12, make described shell fragment 15 no longer compress described swing arm 13 and get final product.

Certainly, cross sectional shape that can described swing arm 13 can be for multiple, for example square, circular or other shapes.Corresponding, the hole 14 of described knob 12 also is designed to corresponding shape, for example, at described swing arm when being square, the hole of described knob comprises the square main body that cooperates with described square swing arm, and is communicated with draw-in groove that offer, that hold the segmental arc that tightens described spring leaf above described square main body.

Above-mentioned rotary switch can be used for culinary agitating device, as shown in Figure 3, can certainly be used for other occasion, for example on the small household appliances such as electric fan, electric light.Described switch main body 11 is arranged in the casing 16 of agitating device, and 13 of described swing arms stretch out described casing 16, and described knob 12 cooperates with described swing arm 13 outside casing 16.For the sealing that guarantees casing 16 and attractive in appearance, between described switch main body 11 and described knob 12, be provided with the switch panel 17 that is used to block described switch main body 11.Described switch panel 17 can be fixed on the described casing 16, also can be fixed on the described switch main body 11.
