Description
Technical field
The present invention relates to a kind of motorcycle part, the spark plug cap particularly in motorcycle engine.
Background technology
Spark plug cap is the vitals in motorcycle engine, and for connecting high-voltage line and spark plug, its quality, directly affects the startability of engine.Existing spark plug cap for motorcycle is generally made up of body, spring, conductive cap, resistance and screw etc., not enough below ubiquity:
1) conductive cap adopts interference fit to be fixed in body, and dismounting is inconvenient, and efficiency of assembling is low;
2) screw is round end structure, must assemble, could realize screw and not rotate in body after cooling under Warm status (about 150 DEG C) high temperature; Moreover, the assembling of other parts is also carry out in hot state, and assembly technology is more complicated so on the one hand, and assembly manipulation is inconvenient, and operator is easy to hand to scald; On the other hand, intrinsic residue is not easy to clean out, and easily causes product poor flow;
3) resistance one end abuts with spring, and the other end abuts with screw, and the contact performance of resistance end face and screw is bad, likely occurs not conducting phenomenon; Meanwhile, the contact-making surface of resistance and spring is little, and the reliability of spring location is poor, easily occurs crooked, causes the conduction between spring and resistance poor thus.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide a kind of spark plug cap for motorcycle being easy to assemble, conduction is good.
Technical solution of the present invention is as follows: a kind of spark plug cap for motorcycle, body (1) is " L " shape, be made up of orthogonal first straight tube (1a) and the second straight tube (1b), the endoporus of the first straight tube (1a) communicates with the endoporus of the second straight tube (1b), its key is: in described first straight tube (1a), install the first spring (2) and conductive cap (3), one end of first spring (2) abuts with at the bottom of the hole of the first straight tube (1a) endoporus, the other end abuts with conductive cap (3), conductive cap (3) and the first straight tube (1a) threaded engagement, in described second straight tube (1b), the second spring (4) is from inside to outside installed successively, resistance (5) and screw (6), described screw (6) is outer-hexagonal tapping screw, the two ends of described resistance (5) are symmetrical arranged fluted, the inner end of the second spring (4) is vertical with the first spring (2) to offset, the outer end of the second spring (4) is stretched in the groove of resistance (5) wherein one end, the other end of resistance (5) stretches in the deep gouge of screw (6) head, two pieces of plum blossom sheets (7) stacked together are set with in the upper position near its head of described screw (6), this plum blossom sheet (7) is placed in the cone section of screw (6) admittedly, the edge of plum blossom sheet (7) bends towards the Direction distortion that screw (6) is most advanced and sophisticated, form a circle cambered surface flange, this cambered surface flange is provided with circumferentially equally distributed external tooth (7a), and described external tooth (7a) offsets with the inwall of the second straight tube (1b).
Adopt above technical scheme, the mounting means of conductive cap changes threaded engagement into by traditional interference fit, not only easy accessibility, and efficiency of assembling is high, and can assemble at normal temperatures, the disadvantage of assembling under eliminating Warm status high temperature.
Resistance wherein one end adopts groove to be connected with the second spring, to the second spring location, the second spring location can be made reliable, can not occur crooked on the one hand; On the other hand, the second spring is larger by the face of groove and Ohmic contact, and conduction property is better.The other end of resistance stretches in the deep gouge of screw head, and resistance and screws contact area are larger, and contact performance is better, can effectively eliminate not conducting phenomenon.Resistance two ends are symmetrical arranged groove, and such resistance is installed does not have directivity, loads the second straight tube faster.
Screw adopts outer-hexagonal tapping screw, utilizes the outer-hexagonal of screw head to match with the second straight tube endoporus, plays anti-rotation, rotate to avoid screw in the second straight tube; Meanwhile, above structure can be assembled at normal temperatures, and the mounting process of whole like this spark plug cap for motorcycle can carry out at normal temperatures, and assembly technology is simple on the one hand, and assembly manipulation is convenient, fast, and hand can not be scalded by operator; On the other hand, intrinsic residue is easily cleaned out, and can effectively prevent product poor flow.
It is fastening that plum blossom sheet utilizes the conical surface on screw to carry out, quick for installation, and fixing is good; The edge of plum blossom sheet has a circle cambered surface flange, and resistance when screw loads the second straight tube is little; After being seated, the external tooth on two pieces of plum blossom sheet cambered surface flange is that pawl shape and the second straight tube inwall offset, and plays location, can prevent screw from coming off out in the second straight tube.
The endoporus of described second straight tube (1b) is inner small and outside big syllogic stepped hole, at the minimal segment of the second straight tube (1b) endoporus, the second spring (4) and resistance (5) are set, the largest segment of the second straight tube (1b) endoporus arranges screw (6), the interlude of the second straight tube (1b) endoporus is interior ten two corner apertures suitable with screw (6) head, and the head of screw (6) stretches into the interlude of the second straight tube (1b) endoporus.Above structural body processing and fabricating is easy, is easy to the demoulding; The part that second straight tube endoporus matches with screw head is interior 12 corner apertures, and anti-rotation is effective on the one hand, and on the other hand, as long as all can be loaded inwardly in interior 12 corner apertures by screw head, assembling is simpler, quick.
The aperture place of described second straight tube (1b) endoporus is provided with taper flaring structure.Taper enlarging plays guiding, so that parts load in the second straight tube.
Beneficial effect: structure of the present invention is simple, be easy to assembling, efficiency of assembling is high, and whole installation procedure can complete at normal temperatures, avoids operator and is burned, and intrinsic residue is easily cleaned out, and can effectively prevent product poor flow; Resistance of the present invention and spring and screws contact area large, contact performance is better, can improve conduction property further.
