Abstract

The utility model relates to a novel pulling switch used for a lighting lamp. Through the cycle structure design of double turning-on and one turning-off, the switch easily solves the problem that when the power failure happens, the lamp which is not surely treated because people does not know the on-off state can not be effectively turned off. The utility model has the advantage of artful conception, and no cost is increased.

Description

Pulling switch

The utility model relates to Switch for lamps.

All now illuminating lamps all are one to close one to open be many loop structures of a circulation with pulling switch, promptly draw a pull-down line rope, circuit turn-on, and electric light is bright; Draw, circuit disconnects again, and electric light does not work; If draw, circuit is conducting again again.There is a problem in this switch when reality is used: in the power supply network sudden power and the user does not pay attention to or do not remember which electric light was to be in out state before outage clearly, or when the user can't know the on off state of electric light for sure under the situation of long-time outage, just can't close processing to it.If deal with improperly will cause when indoor unmanned or ask night sleeping after, power supply network send electricity, some electric lights may be in a Chang Ming (be switch be in out) state always.This not only can cause wasting of a large amount of energy, also can stay other hidden danger.

The purpose of this utility model just provides a kind of new switch designs, to solve the problem that existing switch exists.

The realization the technical solution of the utility model is:

A kind of pulling switch, form by switch enclosure, conducting metal reed, switch runner, fixed axis, spring and backguy rope etc., it is characterized in that: the periphery of switch runner is divided into multiple part of 3, fix a conducting metal reed every two limits, be used for connection circuit, open formation two passes one is many cycling switchs structure of a circulation

Above-mentioned said many cycling switchs structure can be single cycle or two circulations or three circulation or four loop structures.

Compared with prior art, advantage of the present utility model is: do not solved after power failure owing to know that electric light is originally and be in the state of opening or closing and can't be to its problem of correctly handling.Because the utility model is two passes, one structures of opening, therefore, under the situation for city's electrical network sudden power or long-time outage, even the user does not pay attention to or do not remember which electric light whether be in out state clearly before outage, as long as draw switch again, just necessarily can make electric light be in closed condition.

Accompanying drawing is a structure principle chart of the present utility model, and wherein (a) figure is that two loop structure figure (b) of the present utility model are three loop structure figure of the present utility model.

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

In the accompanying drawings, 1 is the switch runner, 2 conducting metal reeds, and 3 is conductive metal sheet, 4 is the runner gear teeth, 1. and 2. and 3. and 4. is respectively the diverse location on switch runner 1 periphery.Conducting metal reed 2 links to each other with power supply network, the periphery of switch runner 1 is divided into multiple part of 3, as hexagon, nonagon etc., each limit is separated by the runner gear teeth 4, fix a conductive metal sheet 3 every two limits, be used for connection circuit, and other parts of switch are all identical in existing stayguy switch fabric, so just forming one is the switch of circulation open-close-close-open-close-close-to open.When using switch, if to begin be when being in conductive metal sheet 3 contacted positions 1. to conducting metal reed 2, the state that switch is in out; Pulling backguy rope, switch runner 1 rotates, and 2. conducting metal reed 2 crosses the gear teeth 4 in-positions, and conducting metal reed 2 disconnects with conductive metal sheet 3, and switch then is in the state of pass; Spur the backguy rope again, conducting metal reed 2 is crossed gear teeth 4 again and is advanced to the position 3., and conducting metal reed 2 still disconnects with conductive metal sheet 3, and switch still is in the state of pass; When spurring the backguy rope for the third time, conducting metal reed 2 is crossed gear teeth 3 again and is 3. advanced to the position 4. by the position, and conducting metal reed 2 contacts with conductive metal sheet 3 once more, the state that switch then is in out again.

Use the utility model, when having a power failure, if switch is the state (being that 1. conducting metal reed 2 is in the position) that is in out, as long as draw switch, switch will cut out; If switch is the state (being that 2. conducting metal reed 2 is in the position) that is in the pass, as long as draw switch, switch remains closes.That is to say when having a power failure, no matter switch leaves or closes,, just can make switch be in the state of pass as long as draw switch again.

Accompanying drawing (a) has provided the structures that the utility model is two circulations, promptly when the switch runner is hexagon, and a kind of special case that conductive metal sheet 3 installs on the switch runner.

Accompanying drawing (b) has provided the structures that the utility model is three circulations, promptly when the switch runner is nonagon, and the another kind of special case of 3 devices of conducting metal on the switch runner.

Claims

1, a kind of pulling switch, form by switch enclosure, conducting metal reed, switch runner, fixed axis, spring and backguy rope etc., it is characterized in that: the periphery of switch runner is divided into multiple part of 3, fix a conductive metal sheet every two limits, be used for connection circuit, open formation two passes one is many cycling switchs structure of a circulation.

2, according to the described pulling switch of claim 1, it is characterized in that: said many cycling switchs structure can be single cycle or two circulations or three circulation or four loop structures.
