Description

Switch on wall

Technical field:

The utility model relates to a kind of switch that is installed on the wall, specifically is a kind of switch on wall that is used to switch on and off the household electrical appliance power supply.

Background technology:

As shown in Figure 6; The seesaw support 88 that existing switch on wall generally comprises panel 80, housing 89, button 81, fork 82, stage clip shell fragment 86, seesaw 85, holder 91 and is connected holder 91 tops, holder 91 are contained in housing 89 intracavity bottoms, and housing 89 tops are buckled on the panel 80; Fork 82 is rotatably connected to housing 89 tops through the rotating shaft 83 at self two ends; Button 81 is contained in fork 82 tops, and seesaw support 88 is supported on seesaw 85 middle parts, and the two ends of stage clip shell fragment 86 are buckled on the seesaw 85; Stage clip shell fragment 86 middle parts are provided with the groove 84 of a V-arrangement, and fork 82 bottoms withstand in the groove 84.The operation principle of above-mentioned switch on wall is: when making fork 82 left and right swings when user's pressing keys 81 two ends; Can exert pressure to groove 84 sidewalls in fork 82 bottoms; After stage clip shell fragment 86 is stressed this pressure successively is delivered to the two ends of seesaw 85; Seesaw 85 is swung back and forth on seesaw support 88, thereby moving contact 87 that is connected seesaw 85 two ends and the fixed contact 90 that is arranged on the junction block 92 are touched in turn, realize connecting and disconnecting of the circuit.Because generally all there is foozle (material thickness like seesaw 85 two ends is unequal) in seesaw 85; After the assembler was buckled in stage clip shell fragment 86 on the seesaw 85, seesaw 85 two ends can be out of shape inconsistent under the elastic force effect of stage clip shell fragment 86, thereby when the moving contact 87 that causes being contained in seesaw 85 two ends touches fixed contact 90 respectively; The left and right pendulum angle of seesaw 85 is unequal; And then finally influence the pendulum angle of button 81, make button 81 two ends inconsistent apart from the height of panel 80 during perk respectively, especially when a plurality of switch on wall are installed side by side; The left and right swing difference in height of button 81 can be more obvious, influences attractive in appearance.

The utility model content:

The technical problem that the utility model will solve is to provide a kind of and can remain the consistent switch on wall of button pendulum angle.

The technical solution of the utility model is that a kind of switch on wall with following structure is provided: comprise panel, housing, button, fork, stage clip shell fragment, seesaw, holder and the seesaw support that is connected the holder top, holder is contained in the housing intracavity bottom; Housing top is buckled on the panel, and fork is rotatably connected to case top through the rotating shaft at self two ends, and button is connected the fork top; The seesaw stent support is at the seesaw middle part; The two ends of stage clip shell fragment are buckled on the seesaw, and stage clip shell fragment middle part is provided with groove, and the fork bottom withstands in the groove; Wherein, Rotating shaft is provided with the swing sheet, and the housing internal chamber wall is provided with the positive stop lug boss of two levels, and the swing sheet is between the positive stop lug boss of two levels.

The described switch on wall of the utility model, wherein, bottom portion of groove can be a plane that supplies the fork basal sliding.

The described switch on wall of the utility model, wherein, bottom portion of groove can be an arcwall face that slightly raises up that supplies the fork basal sliding.

The described switch on wall of the utility model, wherein, swing sheet bottom can be provided with open slot.

After adopting above structure, compared with prior art, the utility model switch on wall has the following advantages: because the rotating shaft of the utility model switch on wall is provided with the swing sheet; The housing internal chamber wall is provided with the positive stop lug boss of two levels; And swing sheet between the positive stop lug boss of two levels, therefore, when making the left and right swing of fork when user's pressing keys two ends; The positive stop lug boss of two levels can be limited the left and right pendulum angle of fork; The left and right pendulum angle that makes fork equates all the time, like this, the button two ends that are contained in the fork top respectively during perk the height apart from panel also just be consistent.

The setting of the plane of bottom portion of groove or the arcwall face that slightly raises up can make between fork bottom and the groove two side and form the gap; Like this; When the left and right swing of fork; Fork bottom can contact with recess sidewall behind the segment distance that slides on plane or the arcwall face again, contacts reliably with fixed contact on being arranged on junction block thereby further guaranteed to be connected the moving contact at seesaw two ends.

The setting of open slot can make the swing sheet produce elasticity when swing sheet and positive stop lug boss touch, thereby the feel during increase user pressing keys promptly is unlikely to very stiff when user's pressing keys.
