Abstract
A universal engine spark plug cap is characterized in that a conductive cap is a stainless steel cylinder (8) whose axial direction is provided with a though slot, one end of the cylinder (8) is provided with an underside block (9), the cylinder (1) is squeezed into a body (1) with the end of the underside block (9) passing through a pad (6) and contacting an electric resistance (2), the other end thereof is sleeved with circlips (7) whose bayonet winds through the through slot on the cylinder (8) and falls on the surface of the cylinder (8), a locking mouth (10) is radially arranged on the surface of the cylinder (8) where the circlips (7) is fixed. The locking mouth (10) is provided on the opposite of the through slot of the cylinder (8) and a portion of the circlips (7) falls into the fixation mouth (10). The universal engine spark plug cap has the characteristics of simple structure, low cost and reliable property. The connection of the stainless steel cylinder and the body by squeezing prevents the connection with the body by screws and the loosening resulted from the host machine vibration. The adoption of the stainless steel cylinder as the conductive cap is not only convenient for processing, beneficial for the park plug rod inserting into the cylinder (8), but also provided with strong corrosion resistance.
Description
One, technical field:
The utility model relates to ignition coil, especially the general purpose engine spark plug cap.
Two, background technology:
At present, the igniter on the domestic logical machine, employed spark plug cap is by body and be contained in intrinsic conductive cap, resistance, spring, reed, screw composition, and wherein screw is positioned at the arm of body, and conductive cap is installed in the entrance point that body is responsible for.Because employed conductive cap is the copper conductive cap, it has blind hole by being threaded in the body in the outer end of copper conductive cap, and the blind hole outer wall is installed collar, and this copper conductive cap cost is expensive, does not have on market and strives power, is unfavorable for the development of enterprise.
Three, utility model content:
The purpose of this utility model provides a kind of reliable operation, the general purpose engine spark plug cap that cost is low.
The purpose of this utility model is achieved in that a kind of general purpose engine spark plug cap of design, comprise body and be contained in intrinsic resistance, spring, screw, conductive cap, its key is: conductive cap is the stainless steel cylinder, axially have straight joint on this cylinder, an end of cylinder is provided with bottom surface block; Described cylinder is squeezed in the body, and its bottom surface block end contacts with resistance by pad, and the other end is set with jump ring, and the bayonet socket of this jump ring is walked around the straight joint on the cylinder, drops on the drum surface, radially has the locking mouth on the drum surface that the jump ring place is installed.
Described jump ring is a wire spring, and elasticity and locking are better.
Locking mouth on described stainless steel drum surface is bar shaped, and this locking mouth is positioned at the opposite of cylinder straight joint, and the part jump ring falls within the locking mouth.
Adopt the advantage of such scheme to be: simple in structure, cost is low, dependable performance, and the stainless steel cylinder is connected with body by extruding, has avoided being connected with body by screw thread the becoming flexible of the conductive cap that causes because of the vibrations of main frame.Adopt the stainless steel cylinder to make conductive cap, not only easy to process, be beneficial to the spark stopper rod and insert in the cylinder 8, and corrosion resistance is strong.
Four, description of drawings:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the expanded view of stainless steel cylinder 8 among Fig. 1.
Fig. 3 is the installation diagram of stainless steel cylinder 8 and jump ring 7 among Fig. 1.
Five, embodiment:
Please see Figure 1, Fig. 2, Fig. 3, the utility model mainly is made up of body 1, resistance 2, spring 3, reed 4, screw 5, pad 6, jump ring 7, stainless steel cylinder 8, wherein resistance 2, spring 3, reed 4, screw 5, pad 6, jump ring 7, stainless steel cylinder 8 are contained in the body 1, annexation between them is, resistance 2 one ends contact with stainless steel cylinder 8 through pad 6, the other end and spring 3 butts, spring 3 is connected with screw 5 by reed 4, screw 5 is positioned at the arm of body 1, and stainless steel cylinder 8 is positioned at the entrance point of body.Its main points are: stainless steel cylinder 8 is conductive cap, axially has straight joint 11 (as Fig. 3) on this cylinder 8, and an end of cylinder 8 is provided with bottom surface block 9 (as Fig. 2); Described cylinder 1 is squeezed in the body 1, its bottom surface block 9 ends contact with resistance 2 by pad 6, the other end is set with jump ring 7 (as Fig. 1), the bayonet socket of this jump ring 7 is walked around the straight joint on the cylinder 8, drop on cylinder 8 surfaces and go up (as Fig. 1, Fig. 3), on cylinder 8 surfaces that jump ring 7 places are installed, radially have locking mouthful 10 (as Fig. 2).Described locking mouth 10 is bar shaped (as Fig. 2), and this locking mouth 10 is positioned at the opposite of cylinder 8 straight joints, and part jump ring 7 falls within the locking mouth 10 (as Fig. 3).Described jump ring 7 is wire springs, and elasticity is better.
The utility model is made tubular with stainless steel cylinder 8, not only is convenient to processing, and the spark stopper rod is inserted.End at cylinder 8 is provided with bottom surface block 9 (as Fig. 1, Fig. 2), can increase the contact area of cylinder 8 and pad 6, improves conductivity and stability.
When the utility model uses, the body end tie point fire coil of screw 5 is housed, the body end that stainless steel cylinder 8 is housed connects spark plug.When the spark stopper rod inserted in the cylinder 8, the straight joint on the body had telescopic action, was beneficial to insert in the cylinder 8, then by jump ring 7 lockings.Walk around straight joint on the cylinder 8 because of the bayonet socket of jump ring 7, over against cylinder 8 surfaces, rather than the bayonet socket of jump ring 7 is over against the body straight joint, in addition, the opposite of straight joint is unblanked fixed mouthful 10, and part jump ring 7 sees through locking mouth 10 and directly contacts with the spark stopper rod that inserts, so locking action is preferably arranged.
