Abstract
The utility model discloses a microswitch which includes a lower seat body and an upper cover body arranged on the lower seat body; the lower seat body is provided with a dynamic wafer and a static wafer by a post head; a button body penetrating the upper cover body points at the dynamic wafer; an elastic seal sleeve is sheathed on the button body; the inner end of the post head is a blind hole; the outer end is a screw hole; the elastic seal sleeve is in a loudhailer shape; the large opening end of the elastic seal sleeve is mounted in a counter bore on the upper cover body for the button body to be penetrated; an elastic check ring is arranged between the large opening end of the elastic seal sleeve and the counter bore. The utility model has a simple structure and reliable functions, is simple and easy to be used and maintained and is suitable for being matched to be used with a backup buzzer on a farm vehicle, a tractor and other agriculture machinery.
Description
Technical field
The utility model relates to a kind of sensitive switch, especially a kind of sensitive switch that is used with backup buzzer.
Background technology
The existing sensitive switch that is used with backup buzzer on agricultural vehicle, tractor and the Other and Agricultural Machines that is installed in, generally be that upper cover body is installed on lower base, by binding post movable contact spring and static contact are installed in the lower base, pass the button body of upper cover body and point to movable contact spring.But existing button body is the through hole that passes the upper cover body end face points to movable contact spring, between the through hole on button body and the upper cover body end face without any seal approach, because the operational environment of sensitive switch is more abominable, dust, foreign material and water easily enter from the through hole of lid end face, cause the sensitive switch misoperation.In addition, the binding post in the sensitive switch is a through hole in the middle of it, inner with bolt connection movable contact spring and static contact, the outer end is a screwed hole, connects lead by bolt, this frame mode makes water be easy to enter sensitive switch by binding post, causes sensitive switch work malfunctioning.
Summary of the invention
The technical problems to be solved in the utility model provides the sensitive switch of a kind of good airproof performance, stable work in work.
For solving the problems of the technologies described above, the utility model comprises lower base and is installed in upper cover body on the lower base, by binding post movable contact spring and static contact are installed in the lower base, pass the button body of upper cover body and point to movable contact spring, its design feature is to be set with elastic seal cartridge on the described button body.
As to improvement of the present utility model, described binding post the inner is a blind hole, and the outer end is a screwed hole.
As to further improvement of the utility model, described elastic seal cartridge is the loudspeaker tubular, and its big opening end is installed in the counterbore that passes for button body on the upper cover body, is provided with circlip between described elastic seal cartridge big opening end and the described counterbore.
As further improving of the present utility model, the seam crossing between lower base and upper cover body scribbles fluid sealant.
After adopting said structure, owing on button body, be set with elastic seal cartridge, improved the sealing property between the through hole on button body and the upper cover body end face, dust, foreign material and water can not enter in the sensitive switch from the through hole of lid end face, stable work in work, it is simple in structure, reliable in function, and working service is simple and easy.And binding post the inner is a blind hole, and the outer end is a screwed hole, and water can not be entered in the sensitive switch along binding post, further improves its sealing property; Seam crossing between lower base and upper cover body scribbles fluid sealant, and sealing property is better.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is the structural representation in the utility model vertical section.
Embodiment
With reference to accompanying drawing, this sensitive switch comprises lower base 9 and is installed in upper cover body 6 on the lower base 9, and by binding post 10 movable contact spring 12 and static contact are installed in the lower base 9, binding post 10 the inners are blind hole, and the outer end is a screwed hole.Binding post 10 has 3, and wherein there is movable contact spring 12 the inner by rivet 8 riveted joints, and other two the inners are riveted last static contact 11, following static contact 13 respectively by rivet 8, are provided with in the screwed hole of binding post 10 outer ends to connect lead bolt 15.On upper cover body 6, be provided with the counterbore that passes for button body 1, pass the button body 1 of upper cover body 6 and point to movable contact spring 12, on button body 1, be set with elastic seal cartridge 2, this elastic seal cartridge 2 is the loudspeaker tubular, have a big opening end and an osculum end, button body 1 penetrates this elastic seal cartridge 2 from the osculum end, stretch out from big opening end, its big opening end is installed in the counterbore that passes for button body 1 on the upper cover body 6, be provided with circlip 3 between described elastic seal cartridge 2 big opening ends and the described counterbore, deviate from from counterbore to prevent elastic seal cartridge 2 tail ends, also with sealing fully between button body 1 and the upper cover body 6, prevent dust simultaneously, foreign material and water easily from the lid end face for button body 1 pass the hole enter in the switch.The pressing plate 4 of actuation button body 1 is installed by jointed shaft 16 on the journal stirrup of upper cover body 6, between pressing plate 4 and upper cover body 6, be provided with spring 7, be respectively equipped with pressing plate projection 5, loam cake projection 17 corresponding on the pressing plate 4 at spring two ends about in the of 7 and the upper cover body 6, with fixing spring 7.Be provided with fixed installation hole 14 on lower base 9, for further improving sealing property, the seam crossing between lower base 9 and upper cover body 6 scribbles fluid sealant.
