Abstract
The invention relates to a seal structure of a spark plug. The seal structure comprises a spark plug, a cylinder cover, a steel sleeve of the spark plug and a pressing sleeve, wherein the spark plug is positioned at the top of the cylinder cover, and the bottom of the spark plug is screwed in the cylinder cover; the steel sleeve of the spark plug sleeves the spark plug; the cylinder cover is connected with the steel sleeve of the spark plug; the pressing sleeve is screwed in the steel sleeve of the spark plug, wherein the spark plug comprises a metal casing and a central electrode; the central electrode is arranged in the metal casing, and the bottom of the metal casing is screwed in the cylinder cover. The seal structure disclosed by the invention enables the sealing performance to be more lasting and efficient, and periodic replacement and maintenance of the spark plug are facilitated.
Description
Technical field
The present invention relates to a kind of spark plug sealing structure.
Background technique
Spark plug (spark plugs), is commonly called as nozzles, and its effect is the high voltage pulse discharge of electricity that high-voltage conducting wires is sent here, and air between disruptive spark plug two electrodes produces electrical spark with the mixed gas in this cylinder that ignites.Main Types has: pseudotype spark plug, edge body projectred nose type spark plug, electrode type spark plug, seat type spark plug, polar form spark plug, face arcing type spark plug etc.The function of spark plug is that the high-tension electricity of volts up to ten thousand is introduced to firing chamber, and produces electrical spark and light mixed gas, coordinates and makes motor work done with ignition system and oil supply system, is jointly determining to a great extent the performance of motor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of spark plug sealing structure that meets the requirement of spark plug exclusion of water oil.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of spark plug sealing structure, comprise spark plug, cylinder cap, spark plug steel bushing and gland, described spark plug is positioned at described cylinder cap top, and its bottom is screwed in described cylinder cap, described spark plug steel bushing is sleeved on described spark plug, and described cylinder cap is connected with described spark plug steel bushing, and described gland is screwed in described spark plug steel bushing, wherein
Described spark plug comprises metal shell and centre electrode, and described centre electrode is located in described metal shell, and the bottom of described metal shell is screwed in described cylinder cap.
The invention has the beneficial effects as follows:
It is more effectively lasting that layout of the present invention makes it sealability, and be convenient to the periodic replacement maintenance of spark plug.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described spark plug sealing structure also comprises rubber ring, and described cylinder cap is connected with described spark plug steel bushing by described rubber ring.。
Further, described spark plug also comprises strip lateral electrode, and described strip lateral electrode is welded on the front port of described metal shell.
Adopt the beneficial effect of above-mentioned further scheme to be; strip lateral electrode is thickened to broadening and shorten its length and come faster the heat in cylinder to be conducted to the metal shell to spark plug; the insulative body portion of centre electrode front end is divided and is designed to not expose; the high temperature being brought to adapt to alcohol fuel burning, effectively protects central electrode.
Further, the bottom of described metal shell adopts and is threaded with described cylinder cap.
Further, described spark plug steel bushing is upper and lower cylinder hollow structure.
