Abstract

A pull switch for indicating the state of switch is composed of ratchet wheel, connecting piece, torsional spring, hanging ring and electric brush. The utility model discloses a improve its upper cover, base, the three component of ratchet on current pull switch's basis, make and cover the different colours that can see out the ratchet and show the on-off state from last, accomplish the purpose of indicating switch. The power-off indicating device has the advantages that the on-off can be indicated when power is cut off, and the purposes of power saving and safety are achieved.

Description

Pull switch capable of indicating on-off state

The utility model relates to a kind of power supply pulling switch, and pulling switch that especially can the indicator cock state belongs to electric switch type.

Be widely used in the pulling switch that family office etc. is located now, all there is not the indication of on off state, in case run into power failure, when the people withdraws from a room, do not know whether electric light closes, after the people leaves, during power supply, electric light will be bright, and running into goes on business does not return for a long time, can cause waste of energy, and occur dangerous easily.

The purpose of this utility model is to provide a kind of pulling switch of energy indicator cock state, it is to form through suitably improving on the basis of existing pulling switch, wherein most of element is identical with existing pulling switch, only improves at particular, can reach the purpose of indicator cock state.

The purpose of this utility model is to realize like this, there is a ratchet to drive its rotation in the existing pulling switch by stay cord, switch once rotates 60 °, so it is expression power connections that three places are arranged in 360 ° of scopes of ratchet, three places are for disconnecting, if make its outer rim be exposed to the switch surface, and coat the purpose that the indication lacquer can reach indicator cock to the ratchet enlarged diameter.

The utility model is described in detail as follows below in conjunction with embodiment:

Embodiment is shown in Fig. 1-4, wherein:

Fig. 1 is the overall structure figure of the pulling switch of indicator cock state.

Fig. 2 is the loam cake figure of the pulling switch of indicator cock state.

Fig. 3 is the base figure of the pulling switch of indicator cock state.

Fig. 4 is the ratchet figure of the pulling switch of indicator cock state.

1 is loam cake among the figure, and 2 is base, and 3 is ratchet, and 4 is screw, and 5 is lug plate, and 6 is ratchet, and 7 are backguy, and 8 is axle, and 9 is torsion spring, and 10 is link, and 11 is shift fork, and 12 is float electrode, and 13 is brush, and 14 is screw, and 15 is slot, and 16,17 is fixed electrode.

Backguy 7 is placed in the link 10 as can be seen from Figure 1, pulling shift fork 11 during the pulling backguy, shift fork 11 drives ratchet 3, six ratchets 6 are arranged on ratchet, ratchet of backguy pulling, rotate 60 °, so having three 60 ° in 360 ° of scopes is energized, all the other in opposite directions three 60 ° are to cut off the electricity supply, connecting with cutting off is to make two fixed electrodes 16 by the float electrode 12 that is fixed on the ratchet 3 by brush 13,17 through and off on electric, 16,17 receive on the power supply, and ratchet 3 is enclosed within on the axle 8 that is fixed on base 2, on the axle 8 torsion spring 9 is housed, the difference of the utility model and existing pulling switch only is to have covered out a slot 15 last, the enlarged diameter of ratchet 3 is in the slot 15 that can be deep into loam cake 1, and the size of base 2 is done corresponding adjustment, and remaining parts 4-17 all adopts present general part.

The loam cake of redesign, the part drawing of base and ratchet is shown in Fig. 2-4, and a square opening 15 is opened in the top of loam cake, and Kong Shangke covers the thin transparent plastic of one deck and enters the inside to prevent dust and water, and perhaps whole lid is pressed into transparent plastic.The change that base only need adapt to the ratchet size gets final product.The size of ratchet strengthens three places on its circumference, back and is coated with white reflection lacquer 18, with the indicator cock state, white for open, black is the pass.

Also realize easily not increasing complexity because the utility model is full of coming with the improved part of the part of original pulling switch, can not increase cost of manufacture, therefore very easily promote, during for power failure, can accomplish power saving, safety.

Claims

1, a kind of pulling switch of energy indicator cock state, by loam cake, base, ratchet, lug plate, ratchet, backguy, axle and torsion spring, link, shift fork, electrode, brush and screw are formed, and it is characterized in that:

1., ratchet 3 enlarged diameter in the slot 15 that can go deep into loam cake 1, and alternate three places coat the color that is different from body on its circumference;

2., loam cake 1 above open a rectangular hole 15, cover the thin transparent plastic of one deck on the hole.

2, the pulling switch of indicator cock state as claimed in claim 1 is characterized in that: said loam cake can all form with the transparent plastic compacting.

3, the pulling switch of indicator cock state as claimed in claim 1 or 2 is characterized in that: ratchet circumference three places are coated with white reflection coats with lacquer.
