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

Shown in Fig. 2～8, a kind of slide block resetting device switch, comprise button lid 1 and base 7, be provided with between button lid and base the button lid is carried out the resetting device that pressing operation alternately overturns switch contact, described resetting device includes slide block 1, reseting shrapnel 1, slide block 2 22, reseting shrapnel 2 32 and rocking bar 5.

Form open-and-close mechanism by on-link mode (OLM) between button lid and the containing rack, the folding connected mode between button lid and the containing rack also can adopt the folding connected mode such as translation about the slide rail type except adopting the rotary type hinge is connected certainly.One end is provided with L shaped button bit 11 in button lid bottom, button lid lower middle position is provided with cross muscle 12, be provided with cavity volume 41 in the middle of the containing rack 4, containing rack one end is provided with button and covers L shaped button bit 11 button bit 42 of padlock mutually, makes to have formed hinge between button lid and the containing rack and cooperate.

Reseting shrapnel 1 is a day font, and the bottom, two rooms of font reseting shrapnel is relatively set with Z-shaped cantilever shell fragment 311 in day, and the cantilever shell fragment is splayed configuration and is oppositely arranged, and the rib in the middle of day font reseting shrapnel one also can remove, and is the hollow shape.Slide block 1 is square, and the cross section of the protruding block 211 that its both sides, bottom play a driving role is a wedge, and slide block 1 is installed between two cantilever shell fragments 311 of reseting shrapnel 1.

Slide block 2 22 is box-like, the box bottom surface up, the box bottom surface is provided with arc convex 221, box is provided with reference column 222 for four jiaos.Reseting shrapnel 2 32 is bench shape, and its stool face is a day font, and the Si Jiaochu of day font shell fragment face 321 is provided with lead angle 322.

Reseting shrapnel 1 is packed into earlier in the slide block 22, installs slide block 1 again between the cantilever shell fragment 311 of reseting shrapnel 1, is provided with the screens that is connected with reseting shrapnel 1 in the slide block 2 22, is convenient to fixed reset shell fragment 1.Slide block 1 and reseting shrapnel 1 are contained within the slide block 2 22, and be fixing by reseting shrapnel 2 32 encapsulation again, and the lead angle that is provided with on day font shell fragment face of reseting shrapnel 2 32 and four reference columns of slide block 2 22 block the location.The protruding block 211 that the both sides, bottom of slide block 1 are provided with just from reseting shrapnel 32 day font shell fragment face the space protrude downwards.The mounted assembly of slide block and reseting shrapnel is positioned in the cavity volume 41 of containing rack 4 in the lump.The assembly of slide block and reseting shrapnel is fixed in the containing rack by two muscle that chamber wall and centre position are provided with.

The both upper ends thereof of rocking bar 5 is provided with the protruding block 51 that transmits thrust, the cross section of protruding block is trapezoidal shape or is triangular shaped, trapezoidal top or leg-of-mutton top end are the circular-arc of projection, the rotating shaft 53 of rocking bar and the axis hole of containing rack 43 constitute the center of rotation of rocking bars, also be provided with the rotational positioning projection 52 of restriction rocking bar swing on below the rotating shaft of rocking bar, projection also can be set at the two ends of rocking bar wait other modes to limit the swing of rocking bar.The upper lobes piece correspondence of rocking bar is arranged at the bottom of containing rack cavity volume 41.

The L shaped button bit 11 that button covers an end forms the hinge cooperation with the button bit 42 of the corresponding end of containing rack, the button lid is rotated as the center, arc convex 221 contact matching in the middle of the button lid bottom in the middle of cross muscle 12 and slide block 22 backs, the assembly that can promote slide block and whole cooperation with it when button motion moves downward along the cavity volume of containing rack.

The course of work of slide block resetting device switch is as follows:

During initial condition, rocking bar 5 is positioned at a certain initial side of seesaw 6, makes one in two binding posts 71 in the base 7 to be in on-state, and slide block 1 is positioned at the centre position of reseting shrapnel one, and slide block 2 22 is in apart from maximum distance place, rocking bar 5 top.

When external force acts on button when covering, the cross muscle 12 of the bottom of button lid acts on slide block 22 arc convex 221, slide block 2 22 is stressed, the elastic force that overcomes reseting shrapnel 2 32 moves downward, the inclined-plane of slide block one 21 one side projectioies 211 takes the lead in contacting with the projection 51 of the higher side of rocking bar 5, rocking bar is swung along seesaw, slide block 1 overcomes the elastic force of reseting shrapnel 31 under the effect of rocking bar projection reaction force simultaneously,, contact with rocking bar opposite side protruding 51 and produce movement interference along the same direction horizontal slip of rocking bar swing in slide block 2 22 inside with the projection 211 of avoiding its opposite side.The rocking bar swing makes seesaw 6 upsets, thereby has finished the switching of switch contact.

When thrust disappeared, slide block 2 22 reset to initial position under the effect of reseting shrapnel 2 32, and slide block 1 returns to the centre position under the effect of reseting shrapnel 1 simultaneously.When this moment, slide block 2 22 was subjected to thrust again, its motion process was to above-mentioned similar, and direction is opposite.Thus, can realize the alternately upset of rocking bar to the pressing operation of slide block 2 22.

Reseting shrapnel 1 in the slide block resetting device provided by the utility model, the slide block 1 that horizontally slips, reseting shrapnel 2 32, the slide block 2 22 that slides up and down all are parts independently separately, and easy to process, technology is simple, and motion is reliable, and active force is little.
