Description
Technical field
The utility model relates to a kind of spark plug.
Background technology
Conventional ignition plug in using at present both at home and abroad, comprises housing, insulator, grounding nut and central electrode, described housing is connected with lateral electrode, and great majority are the such structures of a central electrode and a lateral electrode.The discharge part of this spark-plug side electrode bend, covers above central electrode, thus covers electric spark, sparking-plug electrode part electric spark is produced to the moment expansion of wink combustion flame, formed and cover and flame arrest effect, weaken electric spark electric heating energy, reduce arcing performance.And after Long-Time Service, the electrode meeting carbon distribution of spark plug, useful life is short, and carbon distribution too much can cause spark plug to scrap, and automobile cannot start.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind ofly to be avoided flame arrest phenomenon and can improve the multipole point automobile spark plug in spark plug useful life.
To achieve these goals, a kind of multipole point automobile spark plug designed by the utility model, comprise housing, insulator, grounding nut and central electrode, described housing is connected with lateral electrode, described lateral electrode comprises four bends upwards extended along housing upper end, described bend is drawn close mutually away from shell one end, described bend is provided with upwards upright discharge part away from the end of shell one end, the region formed between described discharge part is corresponding with described central electrode, bulge loop external diameter being coaxially set with described housing and being less than housing end face is provided with between described lateral electrode and housing end face.
Preferably, described bend is evenly distributed on described bulge loop upper end.
Preferably, described housing comprises the upper shell and lower house that are threaded, and described discharge part, bend, bulge loop and described upper shell integral type are arranged.
Preferably, described housing is provided with threaded portion, described threaded portion is axially arranged with more than one cleaning groove, and described cleaning groove runs through and is arranged on described threaded portion outer surface.
A kind of multipole point automobile spark plug that the utility model obtains, its technique effect is: be provided with four lateral electrodes, and the discharge part of lateral electrode is uprightly arranged, and does not cover in central electrode, not only can avoid flame arrest phenomenon, and the useful life of spark plug can be improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, a kind of multipole point automobile spark plug that the utility model provides, comprise housing 1, insulator 2, grounding nut 3 and central electrode 4, described housing 1 is connected with lateral electrode, described lateral electrode 5 comprises four bend 5-1 upwards extended along housing 1 upper end, described bend 5-1 draws close mutually away from housing 1 one end, described bend 5-1 is provided with upwards upright discharge part 5-2 away from the end of housing 1 one end, the region formed between described discharge part 5-2 is corresponding with described central electrode 4, make discharge part 5-2 can not cover in central electrode 4, flame arrest phenomenon can be avoided, the bulge loop 6 external diameter being coaxially set with described housing 1 and being less than housing 1 end face is provided with between described lateral electrode 5 and housing 1 end face, the setting of bulge loop 6, be conducive to spark plug when mounted, lateral electrode can not collide and pollution with miscellaneous part, ensure the useful life of spark plug.Owing to having four bends and discharge part, the ignition effectiveness of spark plug can be improved, increase the service life.
In the present embodiment, described bend 5-1 is evenly distributed on described bulge loop 6 upper end.
In the present embodiment, described housing 1 comprises the upper shell and lower house that are threaded, is conducive to the dismounting of upper shell and lower house, easy cleaning spark plug, the useful life of extending plug.Described discharge part 5-2, bend 5-1, bulge loop 6 and described upper shell integral type are arranged.
In the present embodiment, described housing 1 is provided with threaded portion 7, described threaded portion 7 is axially arranged with more than one cleaning groove 8, described cleaning groove 8 runs through and is arranged on described threaded portion 7 outer surface, when screwing in corresponding internal thread, effectively can remove the dirt that threaded connection place retains, the problem of arc control plug ablation.
