Abstract
The utility model relates to a switch, in particular to an electric switch, which structurally comprises a switch casing, a center locating gear shaft is arranged in a circular hole at the bottom portion of the switch casing, a pressure spring, a draw arm and a tension spring are respectively sleeved between the bottom surface of the switch casing and the center locating gear shaft, one end of the tension spring is fixed on a pillar at the outer side of the switch casing, the other end of the tension spring is connected with the draw arm, a convex rectangular column is arranged below the center locating gear shaft, the convex rectangular column is sleeved with conducting movable contact plates and a static contact bottom plate component, the static contact bottom plate component is fixed on the switch casing through an inserting groove and screws, and three conducting lugs are arranged on the static contact bottom plate component. Compared with the prior art, the utility model has the advantages that the electric switch is easy to process, does not need components such as springs, steel beads and the like to locate the center shaft and the casing, is simple in assembly and long in service life, is not easy to wear and the like.
Description
Technical field
The utility model relates to a kind of switch, and a kind of appliance switch specifically is provided.
Background technology
At present, be widely used in being used to control on fan and other household electrical appliance pulling switch and the rotary switch of gear, its structure is all very complicated and bother.Cooperating between the central shaft that is used for positioning of rotating and the shell all must rely on other accessories location such as spring, steel ball, causes switch processing, assembling difficulty, and raw material consume big, and production efficiency is low, cost is high.
Summary of the invention
The utility model is at above deficiency, provides a kind of and is easy to not need to rely on other accessories such as spring, steel ball between processing, central shaft and the shell and locatees, and assembling is simple, and is not easy to wear, the appliance switch of long service life.
The technical scheme that its technical problem that solves the utility model adopts is:
There is a circular hole in bottom centre at switch housing, inserts the centralized positioning gear shaft that insulating material is made in the circular hole.To between the central shaft gear bottom surface, be with stage clip, torque arm, extension spring at the switch housing inner bottom surface.One end of extension spring is fixed on the hitching post of shell block outside, and the other end is fixed in the torque arm.By per two adjacent circular arc cambers on two arc plastics shell foots of concentricity gear shaft one and the housing inside circumference face mutually contact be the location of every retaining.At the bottom surface of the arc plastics shell foot of sun gear shaft the rectangular post of a protrusion is arranged, on rectangular post, be with movable contact spring, the static piece bottom plate assembly of conduction.Static piece bottom plate assembly is fixed on the switch housing by slot and Luo silk.The inner surface of static piece bottom plate assembly is provided with fixing three conductor wire ears spaced apart from each other on a semicircle, three conductor wire ears all have a leg to pass base plate to the assembly outside, on another semicircle, be fixed with the conductor wire ear of a long arc shape, respectively there is a bound feet that is used for fixing curved line ear at its lead ear two ends, bipod is pressed the setting of inside radius direction, has a leg all to pass base plate to the assembly outside on the left side of curved line ear.The backguy rotary switch is closed in the switch housing by static piece bottom plate assembly.
A kind of appliance switch of the present utility model compared with prior art, it utilizes the toughness of plastics to make the elasticity angle, has reduced other parts such as spring and steel ball simultaneously, has reduced the wearing and tearing of metal and plastics, also save suitable metal material, further reduced cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of cutaway view of structural front view of appliance switch;
Fig. 2 is a kind of structure vertical view of appliance switch;
Fig. 3 is a kind of structure vertical view (after removing torque arm) of appliance switch;
Fig. 4 is a kind of movable contact spring and static piece bottom plate assembly structural representation of appliance switch.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
A kind of appliance switch, comprise switch housing 1, be provided with centralized positioning gear shaft 2 in described switch housing 1 bottom circular aperture, be arranged with stage clip 3 respectively between described switch housing 1 bottom surface and the centralized positioning gear shaft 2, torque arm 4 and extension spring 5, described extension spring 5 one ends are fixed on the hitching post 6 of switch housing 1 outside, the other end connects torque arm 4, there is the rectangular post 7 of a protrusion described centralized positioning gear shaft 2 belows, described rectangular post 7 is with the movable contact spring 8 and the static piece bottom plate assembly 9 of conduction, described still base plate 9 assemblies are fixed on the described switch housing 1 by slot and screw, and described static piece bottom plate assembly 9 is provided with three conductor wire ears 10.
Described centralized positioning gear shaft 2 is provided with two arc plastics shell foots 11.
A kind of appliance switch of the present utility model in use, under the effect of stay cord 12, drive torque arm 4, torque arm 4 drives centralized positioning gear shaft 2, centralized positioning gear shaft 2 drives movable contact spring 8 and rotates, by by per two adjacent circular arc cambers on the inside circumference face of two arc plastics shell foots 11 of concentricity positioning tooth wheel shaft 2 one and switch housing 1 mutually contact be the location of every retaining, torque arm 4 is under the effect of extension spring 5 and reset.Movable contact spring 8 rotate realize the base plates the inside three conductor wire ears 10 respectively with being switched on or switched off of the conductor wire ear of long arc shape.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection range of the present utility model.
Claims (2)
