Abstract
The utility model discloses an oil and gas sealing structure for the lower portion of a spark plug, comprising an upper housing, and a spark plug sheath, wherein the upper end of the upper housing abuts against and is matched with the spark plug sheath, the spark plug sheath is matched with a nut through screwing, between the bottom end of the nut and the protruding end of the outer side of the spark plug sheath there is provided a gasket, between the inner side ends of the contact faces between the nut and the spark plug sheath there is provided an O-shaped sealing ring, and between the gasket and the spark plug sheath there is also provided a further O-shaped sealing ring. The oil and gas sealing structure for the upper portion of a spark plug can resolve the technical problems of the prior art, and is good in sealing performance and can prevent oil and gas from entering the housing from the top of the spark plug in the process of use, thereby ensuring the normal working of the spark plug, increasing the working efficiency and reducing the unnecessary waste; and is simple in structure and suitable for wide application within industry.
Description
Technical field
The utility model relates to a kind of spark plug, is specifically related to a kind of spark plug top oil gas hermetically-sealed construction.
Background technology
Existing spark plug usually can cause outside oil gas to infiltrate spark-plug body inside and can't allow spark plug work from spark plug tip because of sealing is bad in the course of the work, and efficient is lower, has affected user's normal use.
The utility model content
The purpose of utility model: for addressing the above problem, the utility model provides a kind of spark plug top oil gas hermetically-sealed construction of good seal performance.
Technical scheme: for achieving the above object, the utility model adopts following technical scheme:
A kind of spark plug top oil gas hermetically-sealed construction, comprise upper encloser and spark plug sheath, conflict and be combined with the spark plug sheath in described upper encloser upper end, the spark plug sheath screws with nut and cooperates, pad is provided with packing ring between described nut bottom and the protruding end, the spark plug sheath outside, between the contact-making surface medial extremity of nut and spark plug sheath, be provided with the O RunddichtringO, between packing ring and spark plug sheath, also be provided with the O RunddichtringO.
As optimization, described O RunddichtringO is O type rubber seal.
As optimization, the described spark plug sheath outside also is provided with the adjustment packing ring on the protruding end.
The O-ring seals locking mechanism is the triangular pyramidal sealing, uses screw-threaded coupling.
Beneficial effect: spark plug described in the utility model top oil gas hermetically-sealed construction in use, good seal performance, stop oil gas and entered enclosure interior from spark plug tip, guaranteed that spark plug can work, increased operating efficiency, reduced unnecessary waste, the utility model is simple in structure, is fit to widely used within the industry.
