Description
Technical field
The utility model relates to a kind of switch, the push-button switch of using on especially a kind of household electrical appliance.
Background technology
Existing switch element, normally be connected to come conducting or circuit by touching between the movable contact spring that is connected with button and the static contact, thereby realize the switching manipulation to household electrical appliances, such as the Granted publication number push-button switch with waterproof edges for mentioning in the patent document of CN 2578951Y, form by deciding feeler, pedestal, lower stage clip, movable contact spring, pagoda spring, plain washer, ratchet, little axle, driving lever, compression spring, shell, nut and button assembly, be provided with waterproof edges on the shell of the spacing hole upside of driving lever.This structure working principle is as follows, owing to acting on, compressing of compression spring make driving lever be in upper end position in initial condition, driving lever moves downward when pressing the button, impel ratchet to change the position, suppose that the initial condition ratchet is in low side, then when driving lever moves downward for the first time, ratchet is transformed into high-end from low side, because movable contact spring is contained on the little axle, little axle is driven by ratchet, therefore the change of ratchet position impels the movable contact spring position to follow the upper and lower motion of little axle, thereby realizes deciding conducting or the disconnection of feeler and movable contact spring.Yet above-mentioned push-button switch structure is easy to occur misoperation because without catch means, brings operational inconvenience to the user, and is serious even have a potential safety hazard.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, easy to operate, push-button switch with Lock function.
To achieve these goals, the technical solution adopted in the utility model is: a kind of push-button switch, comprise base, end cap and back-moving spring, base is fixedly connected with end cap, base is provided with static contact, end cap is provided with button, button is provided with ratchet, button is connected with ratchet gearing, ratchet is provided with the rotating shaft with the ratchet matched in clearance, and rotating shaft is provided with the ratchet that cooperates with ratchet, and rotating shaft is provided with the movable contact spring that can be connected with static contact conducting or open circuit towards the end face of base, back-moving spring one end is compressing base, the other end of back-moving spring is compressing rotating shaft, it is characterized in that: the inwall of described end cap is provided with some axial button passages, and the button channel spacing circumferentially is distributed in the button inwall, and be provided with the lock-bit piece between button passage and the button passage, the lock-bit piece is provided with the lock-bit groove of the shape that matches with ratchet.
As further setting of the present utility model, described ratchet and button are wholely set, the end face at ratchet place is provided with the guide vane end stop that the interval circumferentially distributes, guide vane end stop is positioned at button passage and can be along the slippage of described button passage, described ratchet has the lozenges that cooperates with ratchet towards the end face of ratchet, and the lock-bit groove on the described lock-bit piece is the wedge-shaped slot that cooperates with lozenges.
As further setting of the present utility model, described movable contact spring circlewise structure is set in the described rotating shaft, described rotating shaft is provided with movable contact spring stage clip and spacing ring, one end of movable contact spring stage clip is compressing the end face at ratchet place, the other end of movable contact spring stage clip is compressing movable contact spring, and described spacing ring is arranged on the other end that movable contact spring connects the movable contact spring stage clip relatively.
As further setting of the present utility model, described base is fixedly connected with the end cap buckle-type.
Adopt such scheme, the utility model consists of locking by catch means being set to the interlock of button and the rotating shaft at movable contact spring place or separating.Since ratchet with button is wholely set and ratchet on guide vane end stop be positioned at the button passage limited ratchet can only be about the button passage slippage and can not circumferentially rotating, therefore when pressing the button, the rotating shaft that is positioned at ratchet drives rotating shaft by the ratchet that cooperates with ratchet and rotates, the initial position of ratchet be with ratchet on teeth groove coincide and be in the button track, when ratchet drives the rotating shaft rotation, ratchet is run into the lock-bit piece, and ratchet cooperates the location with lock-bit groove on the lock-bit piece, the interaction relation of this moment button disengaging and rotating shaft, when again pressing the button, the button drive shaft drives ratchet and leaves the lock-bit groove, get back to the button passage, this moment, button and rotating shaft were connected.
Below in conjunction with accompanying drawing the utility model is further described.
