Description

Handle type switch device with anti-self locking function

Technical field

The present invention relates to a kind of for conducting and the handle type switch device of cutting off the electricity supply.

Background technology

Existing handle type switch device comprises: pedestal, be arranged on the some paired terminal of base bottom, be arranged in the pedestal and the movable contact spring mutual corresponding with terminal, be arranged on the shell on the pedestal, be arranged on the handle of dialling in the outer casing through hole, dialling the upper end of handle stretches out in the through hole of shell, the downside of dialling handle then is arranged in the pedestal, it axially offers installing hole at the lower end edge of dialling handle, be provided with spring and slide bar in the installing hole, the end of slide bar is stretched out in the installing hole and is offseted with the upper surface of movable contact spring, is provided with the fixing handle centre of gyration of dialling in the enclosure.This switching device in use, the external part of handle is dialled in actuating, the slide bar of dialling the bottom of handle will slide on the movable contact spring surface, movable contact spring is owing to be arranged on the strutting piece of one of them terminal, therefore, along with slide bar reciprocatingly slides on the movable contact spring surface, movable contact spring just can produce reciprocal flip-flop movement, thereby can make the moving contact of movable contact spring end and the fixed contact on the another terminal realize being switched on or switched off.Because this switching device does not have anti-self locking function, therefore, the misoperation of switch takes place very easily during use, thereby influences the safe handling of electrical installation.

Summary of the invention

Technical problem to be solved by this invention is: a kind of anti-self locking function that has is provided, is difficult for taking place the handle type switch device with anti-self locking function of misoperation during use.

In order to solve the problems of the technologies described above, technical scheme of the present invention is: the handle type switch device with anti-self locking function, comprise: shell, be provided with the first terminal and second terminal in the bottom of shell, at the first terminal fulcrum is set, fulcrum is provided with and the first terminal and second terminal corresponding movable contact spring mutually, be provided with in the enclosure and dial handle, upper end at shell is provided with through hole, below through hole, be provided with chute, turning handle is provided with rotating shaft, rotating shaft can be slided in chute, dial the upper end of handle and stretch out in through hole, it axially offers installing hole at the lower end edge of dialling handle, is provided with spring and slide bar in installing hole, the upper end of slide bar is connected with the lower end of spring, the lower end of slide bar is stretched out in the installing hole and is offseted with the upper surface of movable contact spring, also is provided with block dialling on the handle of described enclosure, is provided with the arc self-locking block that cooperatively interacts with block in the inside of shell.

Advantage of the present invention is: the handle type switch device with anti-self locking function of this structure, and simple in structure, have anti-self locking function, be difficult for taking place misoperation in the use.

Embodiment

Describe specific embodiments of the present invention in detail below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, shown in Figure 3, handle type switch device with anti-self locking function, comprise: shell 1, be provided with the first terminal 2 and second terminal 3 in the bottom of shell 1, at the first terminal 2 fulcrum 4 is set, fulcrum 4 is provided with and the first terminal 2 and second terminal 3 corresponding movable contact spring 5 mutually, in shell 1, be provided with and dial handle 6, be provided with through hole 7 in the upper end of shell, below through hole 7, be provided with chute 71, turning handle 6 is provided with rotating shaft 61, rotating shaft 61 can be slided in chute 71 and be formed two revolution fulcrums, dial the upper end of handle 6 and stretch out in through hole 7, it axially offers installing hole 8 at the lower end edge of dialling handle 6, is provided with spring 9 and slide bar 10 in installing hole 8, the upper end of slide bar 10 is connected with the lower end of spring 9, the lower end of slide bar 10 is stretched out in the installing hole 8 and is offseted with the upper surface of movable contact spring 5, also is provided with block 11 dialling on the handle 6 of described shell 1 inside, is provided with in the inside of shell 1 and the block 11 arc self-locking block 12 that cooperatively interacts.

As shown in Figure 1, the switching device of said structure is in off-state, dial rotating shaft 61 on the handle 6 and be in the upper end of chute 71, being arranged on the spring 9 of dialling handle 6 lower ends is in than the relaxation state, since the blocking surface 121 on the arc self-locking block 12 arrange position and block 11 that the position is set is corresponding mutually, can stop that dialling handle 6 rotates, prevent from neglectful the time, running into misoperation takes place when dialling handle 6.

As shown in Figure 2, when needs during with the closed turning circuit of switching device, by setting aside handle 6, rotating shaft 61 slides to the lower end from the upper end of chute 71, be in compactedly than the spring 9 under the relaxed state, block 11 glides and staggers mutually with arc self-locking block 12, removes blocking surface 121 stopping it.Handle 6 is dialled in actuating then, dialling handle 6 drives the slide bar 10 that is arranged on its lower end and slides into the other end from an end of movable contact spring 5, because movable contact spring 5 is supported on the fulcrum 4 on the first terminal 2, as shown in Figure 3, when slide bar 10 slides into the other end from an end of movable contact spring 5, the other end of movable contact spring 5 can contact with second terminal 3, thereby with the

first terminal

2 and 3 conductings of second terminal, at this moment, lower end and its arcwall face 122 that block 11 can slide into arc self-locking block 12 offset, and make this switching device remain on on-state.

As shown in Figure 1, when needs disconnect switching device, directly handle 6 is dialled in actuating, block 11 is subjected to the influence of spring 9 along arcwall face 122 slips of self-locking block 12 downsides, rotating shaft on group handle 6 is reset to the top of chute, slide bar 10 slides on the end of movable contact spring 5 again simultaneously, one end and second terminal 3 of movable contact spring 5 are separated from each other, switching device is disconnected, and the block of dialling on the handle 6 11 stops mutually with blocking surface 121 again, rotating shaft 61 slides to the upper end from the lower end of chute 71, realizes that counter being self-locking to prevent of switching device run into generation misoperation when dialling handle 6 neglectful the time.
