Description
Technical field
The utility model relates to a kind of engine components, particularly a kind of conductive cap for spark plug cap for motorcycle.
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.Traditional spark plug cap is by body and be arranged on the compositions such as intrinsic conductive cap, resistance, spring, reed, screw, the conductive cap used adopts interference fit to be fixed in the supervisor of body, quality of fit is high on the one hand, high to the requirement on machining accuracy of part, can production cost be increased, on the other hand, must hot pressing be at high temperature adopted to assemble, assembly manipulation is inconvenient, and efficiency of assembling is lower, and easily causes the hand of operating personnel to scald.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of spark plug cap conductive cap structure being easy to assemble.
Technical solutions of the utility model are as follows: a kind of spark plug cap conductive cap structure, there is conductive cap body (1), it is characterized in that: the cylinder that described conductive cap body (1) is the uncovered lower end closed in upper end, and the external diameter of conductive cap body (1) epimere is less than the external diameter of hypomere, screw thread (2) is provided with at the outer wall of conductive cap body (1) epimere, the outer wall of described conductive cap body (1) lower end along the circumferential direction has a circle draw-in groove (3), the bottom land of this draw-in groove (3) is provided with an opening (4), draw-in groove (3) is communicated with by the inside of this opening (4) with conductive cap body (1).
Adopt above technical scheme, conductive cap moulding is simple, and processing and fabricating is easy, and cost is low; Conductive cap passes through screw thread and the spark plug cap body threaded engagement of its epimere, and not only required precision is low, easy accessibility, and efficiency of assembling is high, and can assemble at normal temperatures, the disadvantage of assembling under eliminating Warm status high temperature.Annular groove on conductive cap body lower end outer wall for installing jump ring, and can make the straight section of jump ring embed in the opening of card round bottom land, thus ensure that the fastness that jump ring is installed.
Be provided with two circumferentially equally distributed breach (5) in the lower surface of described conductive cap body (1), two breach form flat recesses, stretch into for instruments such as bottle openers, make to turn time conductive cap carries out dismounting more convenient, laborsaving.
As preferably, the open-mouth of described conductive cap body (1) lower end is tubaeform.
By taper seat transition between the end face of described conductive cap body (1) and periphery, play guiding like this during assembling and reduce friction, making assembling easier.
In order to simplified structure, jump ring is clamped more firm, described opening (4) is circular arc, and extends along described draw-in groove (3).
In order to ensure conductivity, make processing and fabricating easier, described conductive cap body (1) is passed through machining by copper bar.
Beneficial effect: the utility model structure is simple, be easy to processing, cost is low, and load the simple process of spark plug cap body, efficiency of assembling is high, and can complete assembling at normal temperatures, avoids operator and is burned.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, Figure 2, Figure 3 shows, the conductive cap of spark plug cap for motorcycle has conductive cap body 1, and this conductive cap body 1 is the cylinder of the uncovered lower end closed in upper end, and preferably passes through machining by copper bar.By taper seat transition between the end face of conductive cap body 1 and periphery, the external diameter of conductive cap body 1 epimere is less than the external diameter of hypomere, is provided with screw thread 2 at the outer wall of conductive cap body 1 epimere.The outer wall of conductive cap body 1 lower end along the circumferential direction has a circle draw-in groove 3, and the bottom land of this draw-in groove 3 is provided with an opening 4, and opening 4 is preferably circular arc, and extends along described draw-in groove 3, and draw-in groove 3 is communicated with the inside of conductive cap body 1 by this opening 4.The open-mouth of conductive cap body 1 lower end is tubaeform, is provided with two circumferentially equally distributed breach 5 in the lower surface of conductive cap body 1, forms flat recess.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection range of claims.
