Abstract
The invention discloses a general engine spark plug cap. The tube body of the main tube (1a) of the body (1) obliquely and integrally extends so that a branch tube (1b) is formed. The main tube (1a) is internally provided with a main tube spring (2) and a steel sleeve (3). One end of the main tube spring (2) is connected with the step surface in the main tube (1a) in an abutting way, and the other end is connected with the steel sleeve (3) in the abutting way. The branch tube (1b) is internally provided with a branch tube spring (4), a resistor (5) and a screw (6) which are installed from inside to outside in turn. The resistor (5) is connected with the main tube spring (2) in the abutting way via the branch tube spring (4). The wall of the steel sleeve (3) is provided with positioning holes (3c). The convex hulls on the internal wall of the main tube (1a) are embedded in the positioning holes (3c). The steel sleeve can be effectively positioned so as to prevent loosing or shedding of the steel sleeve, and thus the general engine spark plug cap has characteristics of being ingenious in design, simple in structure, easy to reconstruct and low in reconstruction cost and is suitable for being applied to various types of general engines.
Description
Technical field
The present invention relates to a kind of engine components, the spark plug cap particularly on general purpose engine.
Background technology
Spark plug cap is the vitals on general purpose engine, for connecting high-voltage line and spark plug, and its quality, the directly startability of the logical machine of impact.Traditional spark plug is by body and be arranged on the compositions such as intrinsic conductive cap, resistance, spring, reed, screw, and the conductive cap used is copper structure, and cost is high.Chinese patent ZL 200620110679.0 discloses a kind of sparking plug cap of general engine on August 1st, 2007, carry out alternative traditional copper conductive cap with steel bushing, although effectively reduce cost, steel bushing is fitted in body, fixing is poor, and steel bushing easily occurs to loosen or come off.
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 sparking plug cap of general engine that effectively can prevent loosening or come off.
Technical solution of the present invention is as follows: a kind of sparking plug cap of general engine, the oblique one of pipe shaft of body (1) supervisor (1a) extends, form arm (1b), described supervisor (1a) is built with supervisor's spring (2) and steel bushing (3), one end of supervisor's spring (2) abuts with the step surface in supervisor (1a), the other end abuts with steel bushing (3), in described arm (1b), from inside to outside successively arm spring (4) is installed, resistance (5) and screw (6), resistance (5) is abutted with supervisor's spring (2) by arm spring (4), it is characterized in that: on the wall on described steel bushing (3) top, have location hole (3c), convex closure on described supervisor (1a) inwall embeds in this location hole (3c).
Adopt above technical scheme, the wall of steel bushing has location hole, the effect of stepping down of this location hole, after the supervisor of steel bushing press-in body, supervisor shrinks, convex closure is formed at corresponding location hole place, this convex closure embeds in the location hole of steel bushing, like this by male-female engagement, can play the effect of location, with prevent steel bushing opposing body be responsible for be moved, thus effectively prevent steel bushing occur loosen or come off.
Opposite side on described steel bushing (3) wall all has location hole (3c), and the location hole (3c) on both sides is symmetrical.Above structure is coordinated with the convex closure that body is responsible for by symmetrically arranged location hole, can strengthen the fastness that steel bushing is installed further.
Described steel bushing (3) forms by rolling after stamped from sheetstock, pad (3b) is formed with at the head end of steel bushing (3), this pad (3b) is positioned at the head end mouth of steel bushing (3), and vertical with the axial line of steel bushing (3).Above structure on the one hand technique is simple, and operation is few, is conducive to steel bushing shaping and reduce costs; On the other hand, pad is formed in steel bushing port, does not additionally take up room, and the good reliability to supervisor's spring location.
Plum blossom sheet (8) is installed with in the upper position near its head of described screw (6), the edge of this plum blossom sheet (8) 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.The edge of plum blossom sheet has a circle cambered surface flange, and resistance during screw loading arm is little; After being seated, the external tooth on cambered surface flange is that pawl shape and branch pipe wall offset, and plays location, can prevent screw from coming off out in arm.
Beneficial effect: the present invention can carry out effective location to steel bushing, occurs to prevent steel bushing to loosen or come off, has the features such as design is ingenious, structure simple, transform easily, improvement cost is low, all applicable on various types of logical machine.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, Figure 2, Figure 3 shows, body 1 by injection mo(u)lding, and is made up of supervisor 1a and arm 1b.The oblique one of pipe shaft of supervisor 1a extends, and forms arm 1b, has the angle of 30 ° between arm 1b and supervisor 1a.At supervisor 1a built with being responsible for spring 2 and being pressed with steel bushing 3.Wherein, steel bushing 3 forms by rolling after stamped from sheetstock, and concrete thickness is determined according to actual needs.Be formed with pad 3b at the head end of steel bushing 3, this pad 3b is circular, is positioned at the head end mouth of steel bushing 3, and vertical with the axial line of steel bushing 3.The inner of supervisor's spring 2 abuts with the step surface in supervisor 1a, and the outer end of supervisor's spring 2 abuts with pad 3b.The wall of steel bushing 3 top opposite side all has location hole 3c, and the location hole 3c on both sides is symmetrical, and on supervisor 1a inwall, the corresponding convex closure formed embeds in this location hole 3c.
As shown in Figure 1, Figure 2, Figure 3 shows, in arm 1b, from inside to outside successively arm spring 4, resistance 5 and screw 6 are installed, one end of arm spring 4 abuts with supervisor's spring 2, and the other end of arm spring 4 abuts with one of resistance 5, and the other end of resistance 5 is spacing by the head of screw 6.Position near its head on screw 6 is installed with plum blossom sheet 8, and the edge of this plum blossom sheet 8 is bending towards the Direction distortion at screw 6 tip, and form a circle cambered surface flange, this cambered surface flange is provided with circumferentially equally distributed external tooth, and external tooth and arm 1b inwall offset.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical staff in the art, all should by the determined protection range of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
