Abstract

The utility model discloses a door lamp switch. A moveable contact tip is respectively arranged on the two sides of a fixed contact tip, a door-controlling key and a spacing plate are installed on one side of one moveable contact tip, and a torsion spring is assembled between the door-controlling key and the spacing plate; besides, the torsion spring is also assembled between the door-controlling key and a housing, and a pin-controlled key installed on one side of the other moveable contact tip is arranged inside with a spring. The utility model which is provided with the convenient use has the advantages that the lamp can be opened and closed according to the automatic identification of the need of the lamp through the opening and the closing of the door, the electrical energy is saved, and the utility model is easy to install.

Description

Door lamp switch

The utility model belongs to a kind of light switch, particularly a kind of door lamp switch.

Lavatory and toilet are owing to seal, and mostly light is darker, and frequent switching lamp is all wanted in daytime, turnover at night, not only bother, and forget after coming out sometimes and close electric light, the waste electric energy.

The purpose of this utility model provides a kind of and uses lamp switch, utilizes the Push And Release of door, and energy automatic switch electric light is easy to use, saves electric energy.

The purpose of this utility model is achieved in that it comprises housing, decides contact and moving contact, the main points of its technical scheme are: in the both sides of deciding contact one moving contact is arranged respectively, at a movable contact first side hinged door control key and limiting plate, assemble torsion spring between gate key and the limiting plate, assemble torsion spring between gate key and housing, eave tile is arranged at the bottom of gate key, so that catch on limiting plate; Under limiting plate, assemble damping wheel; At another contact one side assembling pin control key, there is spring its inside; On the pin control key location gap is arranged, the reed of assembling locating ring and effect locating ring on the housing.

The utility model has the advantages that: by the Push And Release of door, can realize that automatically identification needs with lamp and switch lamp is easy to use, save electric energy, and be easy to install.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the right view of Fig. 1.

Fig. 3 is the vertical view of Fig. 1.

Fig. 4 is a schematic appearance of the present utility model.

See Fig. 1-4, concrete structure of the present utility model is as follows: contact 14 is decided in assembling on the housing 17, decides the both sides of contact 14 and respectively adorns a moving contact 13,15.Connect gate key 5 and limiting plate 7 by hinge on the housing 17 of moving contact 13 1 sides, there is eave tile 12 lower end of gate key 5, catches on limiting plate 7.Assembling torsion spring 6 and 8 on hinge, two arms of torsion spring 6 place respectively on gate key 5 and the limiting plate 7.Two arms of torsion spring 8 place respectively on the inwall of gate key 5 and housing 17.When limiting plate 7 upwards lifts, can act on moving contact 13 and decide contact 14 and contact.Curved working face is arranged at the bottom at limiting plate 7, its below assembling damping wheel 9, and this takes turns the curved working face of contact limiting plate 7, and reed 10 is arranged at the wheel shaft bottom of damping wheel 9, is screwed on the housing 17 to adjust jackscrew 11, is used for adjusting the damping size of damping wheel 9.Side at moving contact 15 has keyhole, pin control key 18 is housed in it, spring 16 is arranged at the bottom of key, location gap 1 is arranged on the key body, the locating ring 2 of assembling energy displacement and stop pin control key 18 is gone back clip 3 on the housing on the housing, its termination effect locating ring 2,, the displacement that locating ring 2 is produced to pin control key 18 directions.Have locating ring to retract hole 4 on the key body of gate key 5, locating ring 2 passes from the hole, and when gate key 5 was upspring, the elastic force that locating ring 2 overcomes reed 3 was pulled.Cover plate 19 also is shown among Fig. 4.

Operation principle: the utility model is installed on the doorframe, and pin control key 18 is relative with the position of door bolt.Each operating state is as follows:

When the people when opening the door outdoors, gate key 5 is upspring under the effect of torsion spring 8, simultaneously limiting plate 7 also is lifted under the drive of eave tile 12, limiting plate 7 makes moving contact 13 engage with deciding contact 14, lamp is promptly bright.

At closing time, gate key 5 is depressed by doorframe in the people goes into, and torsion spring 6 passes to limiting plate 7 with pressure, but because the effect of damping wheel 9, limiting plate 7 can only fall lentamente.Therefore moving contact 13 with decide contact 14 and can not separate immediately, its disengaging time can decide by adjustment jackscrew 11.Can insert lock-joint this moment with door bolt, pin control key 18 is pressed into by latch, pin control key 18 promptly overcomes the elastic force retraction of spring 16, and effect moving contact 15 with decide contact 14 and engage, simultaneously locating ring 2 is under the effect of reed 3, move in the location gap 1 of pin control key 18 and make it locking, though at this moment moving contact 13 with decide contact 14 and separate, but moving contact 15 engages with deciding contact 14, so lamp is still bright.

When before human desires goes out, extracting door bolt, because the locking action of locating ring 2, pin control key 18 can not be ejected by spring 16, and when only opening the door, gate key 5 is upspring, and by the hole 4 that retracts on it locating ring 2 is retracted, pin control key 18 is just upspring, moving contact 15 with decide contact 14 and separate, but this moment, moving contact 13 engaged with deciding contact 14, lamp is still bright.

When the people out after at closing time because gate key 5 is depressed, limiting plate 7 is also depressed thereupon, two moving contacts 13,15 all with decide contact 14 and separate, lamp just extinguishes.
