Utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, dependable performance, and long switch floated and protected structure the life-span, to overcome weak point of the prior art.
By a kind of switch of this object design, float and protect structure, comprise the switch and the travel(l)ing rest that are mutually permanently connected, described travel(l)ing rest is provided with push rod groove, and is equipped with push rod, and described push rod is placed between switch and travel(l)ing rest, and is inserted with spring A; It is characterized in that described travel(l)ing rest is assemblied on casing, is provided with guide pillar and spring B on described casing; Utilize the opposition of dual spring, effectively cushion excessive external force, play a protective role.
At least one guide pillar is set on described casing, and described guide pillar is formed in one or split type being assemblied on casing.
The corresponding guide pillar of described travel(l)ing rest position is provided with guide pillar groove, and casing and travel(l)ing rest plug guide pillar groove by guide pillar and realize assembling and location.
Described guide pillar top is fixedly equipped with block.
Described guide pillar is inserted with spring B, and described spring B is placed between guide pillar groove top and block.
Described push rod one end is inserted in jogger hole A and the jogger hole B arranging on travel(l)ing rest and casing simultaneously, and exposes at least partly casing, and the other end plugs spring A, and is assemblied in push rod groove.
Described push rod surface annular protrusion has a spacing road, and a side prevents that push rod from being skidded off outward by interior, and opposite side acts on spring A, makes push rod realize reseting movement.
Described push rod control switch, and move to before concordant with casing outer surface and complete control at push rod exposed junction.
The stiffness factor of described spring A is less than spring B.
The utility model is by the improvement of said structure, and travel(l)ing rest and casing assemble by guide pillar, is inserted with spring B on guide pillar.When acting on the external force of push rod when moderate, the smooth contact-making switch of push rod is realized control action; When external force is excessive, under the effect of the reverse elastic force of dual spring, part external force is cancelled, and the power that acts on switch is reduced greatly, has effectively protected switch.It has simple and reasonable, dependable performance, the feature that the life-span is long.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
The first embodiment
Referring to Fig. 1-Fig. 2, a kind of switch floats and protects structure, comprises the switch 1 and the travel(l)ing rest 2 that are mutually permanently connected, described travel(l)ing rest 2 is provided with push rod groove 2.1, and be equipped with push rod 3, described push rod 3 is placed between switch 1 and travel(l)ing rest 2, and is inserted with spring A 4; Described travel(l)ing rest 2 is assemblied on casing 5, is provided with guide pillar 5.1 and spring B 7 on described casing 5; Utilize the opposition of dual spring, effectively cushion excessive external force, play a protective role.
Specifically, two guide pillars 5.1 are set on described casing 5, described guide pillar 5.1 is one-body molded with casing 5, the position of the corresponding machine guide pillar 5.1 of described travel(l)ing rest 2 is provided with guide pillar groove 2.3, casing 5 plugs guide pillar groove 2.3 with travel(l)ing rest 2 by guide pillar 5.1 and realizes assembling and location, guide pillar 5.1 is inserted with spring B 7, and this spring B 7 is placed between guide pillar groove 2.3 tops and block 6, and described block 6 is fixedly assemblied in guide pillar 5.1 tops.
Push rod 3 one end are inserted in jogger hole A 2.2 and the jogger hole B 5.2 arranging on travel(l)ing rest 2 and casing 5 simultaneously, and partly expose to casing 5, and the other end is assemblied on push rod groove 2.1 after plugging spring A 4.In addition, the surperficial annular protrusion of push rod 3 has spacing road 3.1, one sides to prevent that push rod 3 from skidding off outward from interior, and opposite side acts on spring A 4, makes push rod 3 realize reseting movement.Described push rod 3 is controlled direct switch 1, and moves to before concordant with casing 5 outer surfaces and complete control at push rod 3 exposed junctions.The stiffness factor of above-mentioned spring A 4 is less than spring B 7, to guarantee push rod 3 control switch 1 smoothly.
The utility model mainly carrys out control switch 1 work by pressing push rod 3.When pressing the active force of push rod 3 when moderate, because spring A 4 stiffness factors are less, so spring A 4 suppressed ranges are larger, and the smooth contact-making switch 1 of push rod 3, reaches control object; External force is cancelled, and under spring A effect, push rod 3 resets.When pressing the active force of push rod 3 when excessive, the opposition that spring A 4 and spring B 7 produce increases, and can obviously offset part external force, reaches buffering effect, and therefore, the power acting on switch 1 reduces greatly, protective efficient switch 1.
The second embodiment
Referring to Fig. 3-Fig. 4, this switch floats and protects structure, and it is different from the first embodiment part and is: described guide pillar 5.1 is split type assembling with casing 5.Guide pillar hole assembling guide pillar 5.1 be set on casing 5 or use screw to connect guide pillar 5.1, or using other modes to connect guide pillar 5.1.
Other does not state part with the first embodiment.
Above-mentioned is preferred version of the present utility model, and those of ordinary skills are to its simple modification or transformation, within all dropping on protection range of the present utility model.
