Abstract
The utility model relates to a switch for electric equipment. A power switch is arranged in the bolt box of a door lock or the power switch is arranged in the bolt box into integration. A switch shell is made of insulating material. The movable contact of the switch of the in and out wiring terminals of wires is arranged on the switch shell. A fixed contact is pressed on an elastic device. An insulating rod which is fixedly connected with the movable contact extends out of the shell and contact the bolt of the door lock. When a door is locked, the insulating rod pushes aside the contact of the movable contact and the fixed contact and a power source is disconnected. But to ensure that the power of a refrigerator or other special electric equipment can not be switched off, a constant electric socket can be led out on the switch.
Description
The utility model relates to a kind of manufacturing of appliance switch.
The household electrical appliance switch can be guillotine type now, and air switch etc. generally are installed in the higher position and can often operate associated overload or overcurrent protective device also only at special fault, and in time cut off the power supply of common electrical appliance in the room for a moment.The useful key card in hotel carries out break-make control to the room circuit, but needs personnel initiatively to its control.In fact, along with increasing of household electrical appliances, the circuit in reply room in time cuts off, otherwise, even electrical equipment is switched off, but plug do not pull out, and the former limit of transformer still is connected on the power supply, still in power consumption, so long-time, easily cause electrical equipment to cross the danger of cause thermal damage and fire, this kind danger can't prevent with existing fuse and air switch, typical in electric blanket, television set, recorder, radio-cassette player etc.
The utility model purpose provide a kind of can be conveniently to the appliance switch that links with door lock of dump in the room, especially can be when the people leaves the turned off in synchronization power supply.
Technical solution of the present utility model is: the dead bolt box of door lock or with dead bolt box one system one mains switch, switch housing is made with insulating material, last live wire turnover binding post switch moving contact is pressed in fixed contact by an elastic device, stretches out the outer and door lock tongue of shell with the affixed insulating bar of moving contact and touches mutually.When locking a door, insulating bar backs down the contact of sound contact, deenergization, but as in order to guarantee constantly electricity of special electrical equipment such as refrigerator, can draw perseverance on switch has electrical socket.
The utility model is simple in structure, and is convenient naturally with dump in the room when locking a door, and not only eliminated danger; and bring convenience for the use of household electrical appliances, also have economize on electricity and to the defencive function of household electrical appliance, and easy for installation; not only can assemble, and be easy to old door lock repacking for new worker-house.
The utility model is described in further detail below in conjunction with accompanying drawing with by embodiment:
Fig. 1 is the utility model structural representation
General the utility model is used for being complementary with the door lock of band double lock tongue, the not action of control switch of auxilliary tongue of lock 1, and main tongue 2 is controlled, according to existing door latch structure, main dead bolt puts in two to three positions in the dead bolt box, cut off the electricity supply in the position in general design will extend, and the insulating bar 3 and the dead bolt of the switch back of colliding is backed down, insulating bar drives the contact contact or disconnects, and the dead bolt box is shaped on accordingly for the flexible breach of two dead bolts.Assurance ought indoorly have man-hour master tongue not to be locked into last lap like this, and when dead bolt did not reach the rearmost position, mains switch did not cut off yet.
Another embodiment makes a shell with the dead bolt box, is wrapped in the shell in the switch, and can regulates in the flexible direction of dead bolt, and is promptly slotted on shell, by screw appliance switch is fixed on position in the dead bolt box.6 have electrical socket for perseverance.
Contact and insulating bar have the structure of a kind of embodiment in the drawings, have provided the break-make of two pairs of contacts among the figure, can control the break-make of two inlet wires simultaneously, and be in fact only also feasible fully with pair of contact, only controls the break-make of live wire.Have groove among the figure in the insulating bar, spring 9 is housed in the groove, it is all good by the contact of a rigid disk 11 holding contacts that spring 10, two springs also are housed in the insulating bar end.
Claims (4)
1. appliance switch that links with door lock, it is characterized in that the dead bolt box of door lock or with dead bolt box one system one mains switch, switch housing is made with insulating material, last live wire turnover binding post, the switch moving contact is pressed in fixed contact by a spring, stretches out the outer and door lock tongue of shell with the affixed insulating bar of moving contact and touches mutually.
2. the appliance switch of being stated by claim 1 is characterized in that the dead bolt box is made a shell, is wrapped in the switch in the shell, and is slotted on shell, by screw appliance switch is fixed on position in the dead bolt box.
3. by claim 1,2 described appliance switches, it is characterized in that drawing on switch perseverance has electrical socket.
4. by claim 1,2 described appliance switches, it is characterized in that having groove in the insulating bar, spring (9) is housed in the groove, spring (10) also is housed in the insulating bar end, two springs all contact with the contact by a rigid disk.
