Abstract

The utility model discloses an automatic controlled illumination switch which is suitable for bathrooms and toilets. The utility model has the technical proposal that a positioning supporting axle and two supporters are arranged on base panels. A ratchet wheel and a switch blade are arranged on the supporting axle. A return spring is connected with the supporters on the switch blade. Switch conduction slices are respectively fixed at teeth valleys which are interphase with the ratchet wheel. A binding post which is connected with a supporter contact piece on the supporters and a binding post connected with a ratchet pawl contact piece which intermittently conducts and spaces with the switch conduction slices on the ratchet wheel are arranged on the base panels. A lever is positioned on the other base panel. One end of the lever is connected with a recoil pullback spring, a pull wire connected with switch slices are fixed on the other end of the lever. The utility model has the advantages of saving time, saving electric, simple structure, convenient installation and high reliability.

Description

Automatic controlled illumination switch

The utility model belongs to a kind of daily life technical field, specifically a kind of toilet, the illuminating automatic switch in lavatory.

Tradition toilet, lavatory lighting switch, the same with other domestic lighting switch, need manually opened, close.That this switch uses is time-consuming, bothersome, in case forget and close, promptly cause power consumption; In difference building, the position that switch is provided with is inequality, and guest Chang Yin can't find switch and a word used for translation is awkward, and particularly old man, child, patient are because of separately former thereby feel more inconvenient.

The purpose of this utility model provides the switch that a kind of people remove the automatic shutter illuminating lamp of toilet, the collision of lavatory gate-type.

The purpose of this utility model is achieved in that it includes a base plate, it is characterized in that base plate is provided with two supports of positioning support axle, on bolster, have a ratchet and switch plate, be provided with the projection that can drive the ratchet one-way rotation at switch plate and the contacted side of ratchet, on the ratchet of correspondence, have groove, be connected with a return spring with support on switch plate, the tooth paddy place alternate at ratchet is fixed with a switch conduction sheet respectively; Be respectively arranged with a binding post that links to each other with support contact chip on the support on the base plate, and be interrupted the binding post that conducting and spacing ratchet contact chip link to each other with switch conduction sheet on the ratchet; On base plate, be positioned with a lever in addition, be connected with a returning pull-spring, be fixed with the backguy that links to each other with switch plate at the other end at the one end.This switch in use, and is first with its top that is installed in inboard doorframe, and an end that makes lever be connected with backguy stretches out doorframe and contacts with door.When door was closing, Locating extension spring was in stress, and backguy is lax, and the ratchet contact chip is against on the no switch conduction sheet position on the ratchet, and be in open position this moment, and lamp is going out; When entering toilet, lavatory, door is opened, and the ratchet contact chip is against having on the switch conduction position on the ratchet, and circuit is in conduction position, the lamp light yellow; After the people comes out and close the door, the ratchet contact chip is against again on the no switch conduction sheet position on the ratchet, and circuit is in open position, and lamp has gone out again.Be a complete use this moment.

The utility model has overcome the shortcoming of toilet, lavatory conventional switch, makes people enter toilet, lavatory, does not need manually opened, off switch, as long as one open the door, lamp is just bright; Between the operating period, lamp is light yellow always, needs only one and gos out, and lamp has just gone out automatically.

The utlity model has save time, save trouble, power saving, simple in structure, easy for installation, safe and reliable, characteristics such as applied range.

Below in conjunction with accompanying drawing this practicality newly is described further.

Fig. 1 is the utility model structural representation.

Fig. 2 is the ratchet simplified schematic diagram of Fig. 1.

Fig. 3 is ratchet and switch plate sectional structure sketch.

Shown in Fig. 1,2,1 is base plate, base plate is provided with two supports 2 of a location bolster 3, on bolster, have a ratchet 4 and eccentric switch plate 5, be provided with one in the side that eccentric switch plate contacts with ratchet and can drive the projection 17 that ratchet one-way rotates, on the ratchet of correspondence, have groove 18, on switch plate, be connected with a return spring 10 with support, the tooth paddy place alternate at ratchet is fixed with a switch conduction sheet 11 respectively, also be respectively arranged with two binding posts 8,9 on base plate, wherein binding post 8 links to each other with support contact chip 7 on being arranged on support; And the switch conduction sheet is interrupted conducting and the rotating ratchet contact chip 6 of spacing ratchet links to each other on another binding post and the ratchet.On base plate, be positioned with a lever 13 in addition, be connected with a returning pull-spring 12, be fixed with a backguy that links to each other with switch plate 15 and guide wheel 16 at the other end at one end and base plate by locating shaft 14.This structure is installed in toilet or the lavatory doorframe top earlier before use apart from 100 millimeters places of door-hinge.When nobody, when door is closing, lamp is going out, and this moment, guide wheel 16 was concordant with base plate 1 limit under the thresholding position, and returning pull-spring 12 is in stress, and 15 of backguys of insulation are in relaxed state, and ratchet contact chip 5 is against on no metal conduction sheet 11 positions of cut-offfing on the ratchet; When entering toilet or lavatory, open door, then lever is subjected to returning pull-spring 12 pulling force to affect backguy, making switch plate drive ratchet rotates, ratchet contact chip 6 is connected with the metal conduction sheet 11 that has on the ratchet, lamp is just bright, this moment, switch plate rotated back into initial position under the return spring effect, and ratchet be the ratchet contact chip spacing down, can not rotate and keep on-state, people to come into the back and close to the doorstep, guide wheel, lever, spring recover state at closing time again, backguy is lax, for next human action is prepared.Therefore, in the toilet, always display a light when Toilet engaged; When the people left, as long as one push the door open, lever was spurred by spring, and backguy drives ratchet by switch plate and rotates, and then the ratchet contact chip enters on the no conducting sheet position in another tooth paddy again and limits its revolution, dump then, and lamp goes out.Close and call, door promotion guide wheel, backguy is lax again, gets ready for next again, and ratchet can not rotate and keep its dissengaged positions under the ratchet contact chip is spacing, and so far this automatic lighting switch has experienced a complete sampling action.
