Abstract
The invention discloses a general engine spark plug cap. An electric conductive cap (3) is in screw thread fit with a min pipe (1a). A screw (6) is an outer hexagon self-tapping screw. Grooves are symmetrically formed in the two ends of a resistor (5). The end of a supporting pipe spring (4) stretches into the groove of one end of the resistor (5), and the other end of the resistor (5) stretches into a countersunk groove in the head of the screw (6). A plum-shaped sheet (7) is fixedly arranged at the position, close to the head of the screw, of the screw (6) in a sleeved mode. The edge of the plum-shaped sheet (7) deforms and is bent towards the tip of the screw (6) to form a circle of cambered surface turnup, and outer teeth (7a) are evenly distributed on the cambered surface turnup in the circumferential direction. The general engine spark plug cap can be assembled at normal temperature, operation workers are prevented from being scalded, residues in the body are easy to remove, and poor breakover of products can be prevented effectively; the contact area between the resistor and the supporting pipe spring and the contact area between the resistor and the screw are large, the contact performance is better, and the therefore breakover performance can be further improved.
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.Chinese patent ZL 200820098167.6 discloses a kind of spark plug cap of general purpose engine on March 18th, 2009, supervisor spring, jump ring and conductive cap are installed in the supervisor of body, install arm spring, resistance and screw in the arm of body, the deficiency of above structure is:
1) conductive cap adopts interference fit to be fixed in the supervisor of 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 arm 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 arm 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 arm spring is little, and the reliability of arm spring location is poor, easily occurs crooked, causes the conduction between arm 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 sparking plug cap of general engine being easy to assemble, conduction is good.
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 conductive cap (3), one end of supervisor's spring (2) abuts with the step surface in supervisor (1a), the other end abuts with conductive cap (3), in described arm (1b), from inside to outside successively arm spring (4) is installed, resistance (5) and screw (6), its key is: described conductive cap (3) and supervisor's (1a) threaded engagement, described screw (6) is outer-hexagonal tapping screw, the two ends of described resistance (5) are symmetrical arranged fluted, the end of arm 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, plum blossom sheet (7) is installed with in the upper position near its head of described screw (6), the edge of this 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).
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 arm spring, can locate on the one hand to arm spring, arm spring is located reliable, can not occur crooked; On the other hand, arm 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, load arm faster.
Screw adopts outer-hexagonal tapping screw, utilizes the outer-hexagonal of screw head to match with a pipe orifice, plays anti-rotation, rotate to avoid screw in arm; Meanwhile, above structure can be assembled at normal temperatures, and the mounting process of whole like this engine spark plug cap 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.
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.
The endoporus of described arm (1b) is inner small and outside big syllogic stepped hole, at the minimal segment of arm (1b) endoporus, arm spring (4) and resistance (5) are set, the largest segment of arm (1b) endoporus arranges screw (6), the interlude of arm (1b) endoporus is interior ten two corner apertures suitable with screw (6) head, and the head of screw (6) stretches into the interlude of arm (1b) endoporus.Above structural body processing and fabricating is easy, is easy to the demoulding; The part that pipe orifice 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, fast.
Beneficial effect: assembly technology of the present invention is simple, and efficiency of assembling is high, can complete assembling 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 arm spring and screws contact area large, contact performance is better, can improve conduction property further.
