Description

The button power change-over switch

The utility model relates to a kind of power change-over switch, refers to a kind of button power change-over switch that utilizes button switch key control seesaw to move especially.Because moving up and down, seesaw make first conducting strip and second conducting strip form path or off state, the power change-over switch that is beneficial to electric power starting or closes.

See also shown in Fig. 1～3, disclose existing power change-over switch among the figure and mainly combined by a base 10, guide card group 11, rotating disk 12 and loam cake 13; Wherein, be an accommodation chamber 101 in the base 10, the both sides of accommodation chamber 101 are provided with groove 102, and the center is also fixed a hollow cylinder 103, and the place, two ends in accommodation chamber 101 is provided with a clip projection 104 respectively, and a briquetting 105 is equipped with at the two ends, top of base 10 in addition; This guide card group 11 comprises two corresponding fixedly lateral plate 111 and rotation guide cards 112, fixedly lateral plate 111 is to be clamped on clip projection 104 outboard ends, its top is connected with one can make power line 20 pivot ends 22 insert the solid portion of piercing through 113, one side place and the arc swing arm 114 of extending a strip; This rotation guide card 112 is to be placed in the cylinder 103, and its two corresponding end respectively is provided with a guide card 115;

Rotating disk 12 is that cover is fixed on the hollow cylinder 103, its card 121 also protrudes in outside base 10 grooves 102, the control part 122 of these card 121 belows is to be just like windmill shape, and two corresponding fan sheets 123 just can be placed in 115 of the bi-conductive plates of rotation guide card 112,115 of the bi-conductive plates of its control part 122 when card 121 rotation, but its control part 122 driven rotary guide cards 112 rotations when card 121 rotations, and, this guide card 115 is threaded to two when fixedly the swing arm 114 of lateral plate 111 contacts, two pivot ends 22 of power line 20 can form path, and can carry out the conveying (as shown in Figure 2) of power supply with normal open end 21 simultaneously.

If rotating disk 12 continues rotation, this guide card 115 can separate with two swing arms 114, makes circuit be an off state (as shown in Figure 3); Moreover, on base 10, installed loam cake 13, and utilized a locking bar 106 and a nut 132 that it is locked mutually, but the shrinkage pool 131 that power supply source line 20 places is located and be provided with in below, the two ends of this loam cake 13.When loam cake 13 is fixed on the base 10, the briquetting 105 of base 10 is to suppress power line 20, is fixed in steadiness on the power line 20 to increase diverter switch, yet, though the effect that the diverter switch of this structure can reach power turn-on or open circuit only still can produce following shortcoming when reality is used:

1. this power change-over switch is easily because of the improper rotation of rotating disk, makes the guide card can't be smoothly and two swing arms contacts (or separation), therefore, fails the unlatching of certain control circuit.

2. rotating disk is when control circuit opens and closes, and the direction of rotation is all same direction (turning clockwise) if reverse rotation (being rotated counterclockwise) then can cause two swing arms distortion accidentally, or produces the anxiety of fracture.

3. rotating disk also can cause guide card to break away from the fan sheet of rotating disk when careless counter-rotating, causes the loose situation of assembly, and then can't reach the effect of expection.

The pivot end of power line press solidly in fixing lateral plate pierce through portion the time, easily deviation, the displacement because of fixedly the time contacts this portion of piercing through electric wire of failing with in the articulated section that can't puncture smoothly, so the difficulty of formation circuit turn-on.

5. this diverter switch mainly utilizes the briquetting of base to be folded on the power line, but, the briquetting of these base both sides, does not have in its structure to strengthen the fixing design in hub side when using admittedly and fail effectively that performance inserts and puts function in group yet, thus have structural a little less than, shortcoming that spoilage is high.

6. guide card and swing arm be when power supply switches, and because of must making it contact or separate by the rotating disk rotation, fails rapid Switching power so cause, and the anxiety of initiation spark generation is arranged.

7. this diverter switch is with the sealed nut of locking bar base and loam cake to be interfixed, yet the mode of establishing with lock lock not only often takes place established pine, and it is bad to form conduction, easilier establishes tension because of lock, causes sliding tooth and can't reach fixing situation.

Main purpose of the present utility model provides a kind of mutual start that utilizes switch key and seesaw, with the button power change-over switch of control power supply keying; This seesaw is that group is fixed on the seesaw support of first conducting strip, the spine of first conducting strip and second conducting strip is positioned at the base insertion slot, and be connected with the pivot end of power line respectively, therefore, when switching part is pressed on time to an end, the brake bar of its below promptly by the seesaw clamping groove force seesaw bottom free end upwards (or downwards) move so that circuit is a state that opens circuit (or conducting), be one to switch fast and the certain power change-over switch structure of start.

Another purpose of the present utility model provides a kind of two end pivot ends that make power line, certain and button power change-over switch first conducting strip, the second conducting strip conducting; It mainly utilizes the press strip of lid directly to oppress pivot end, so that pivot end is forced in the V-shaped groove of insertion slot, and the spine that is subjected to two conducting strips respectively pierces through, and positively utilizes the seesaw turn-on power smoothly.

A purpose more of the present utility model provides a kind of button power change-over switch that prevents that lid from getting loose; It mainly is the buckle ear that is provided with the buckling groove combination in the base groove side, and the outside, below of buckle ear also convexes with a teat, to be snapped in the fastening hole, this base and lid is interfixed closely.

The purpose of this utility model can reach by following measure:
