The utility model content
The purpose of the utility model is, overcomes the defective that existing braking light switch exists, and a kind of braking light switch of new structure is provided, and makes not cracky of its product, long service life, and product qualified rate is high.
The above-mentioned purpose of the utility model adopts following technical scheme to realize.The braking light switch that proposes according to the utility model has housing, seal membrane, push rod, movable contact spring, moving contact, fixed contact, binding post, spring, base, nut, bullet pad and plain cushion, is provided with screw thread and air admission hole above the housing, and screw thread links with the braking main valve; Seal membrane is loaded between housing and the base, seal, push rod be loaded on seal membrane above; Be used to transmit stroke; Movable contact spring is loaded on above the push rod, moves simultaneously with movable contact spring, and moving contact is riveted on above the movable contact spring; Move simultaneously with movable contact spring, be used for the connection of switch; Moving contact and binding post are riveted together, and binding post is one section circuit above the stop, tail and number plate light, and spring is fixed in base position, links with push rod, plays cut-off signal, and nut, bullet pad and plain cushion are used to lock binding post; Be provided with one deck folder cloth above the said seal membrane, add the anticreep boss around the described seal membrane, it contacts with the housing line.
The utility model solves its technical problem and can also adopt following technical measures further to realize.
Though said folder cloth can be implemented with any cloth, is preferably nylon material.
Though said boss can adopt any boss shape, preferred ball ring body.
The utility model compared with prior art has tangible advantage and beneficial effect.Can know that by above technical scheme the utility model is set up one deck folder cloth owing to adopt technique scheme on the seal membrane of braking light switch, strengthened the intensity of seal membrane, has solved the damaging problem of seal membrane; Around seal membrane, increase the anticreep boss; Make seal membrane in the reciprocating motion process, can lock better, what especially diaphragm did not stop to bend in the reciprocating motion process local destroys easily; We have done sufficient consideration at this design; Air tight, further improved the qualification rate of product, prolonged useful life and can reach 1,000,000 times.
In sum, the utility model really belongs to innovation on the kenel of space, and has the multinomial effect of enhancement than existing product, and simple in structure, is suitable for practicality, has the extensive value of industry.It is in limited field, technical development space; No matter structurally or bigger improvement all arranged on the function; And have large improvement technically, and produced handy and practical effect, and have the effect of enhancement really; Thereby being suitable for practicality more, really is the new design of a novelty, progress, practicality.
Above-mentioned explanation is merely the general introduction partly of the utility model technical scheme characteristic; For making the professional and technical personnel can more know the technological means of understanding the utility model; And can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.
The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
