Abstract
A spark plug for a combined-type gas engine relates to a spark plug, which comprises a housing (1), an automobile-used spark plug (2), a center conducting rod (3), an insulating rubber tube (4), and an insulation tube (5). An upper joint and a lower joint (6 and 7) are respectively fixed at the upper end and the lower end of the housing (1); a side window (8) is formed on the side wall of the housing (1) and near the lower joint (7); internal threads are formed on the lower joint (7); the automobile-used spark plug (2) is wound on the internal threads of the lower joint (7); a screwdriver groove (12) is formed at the upper end of the center conducting rod (3); the lower end of the center conducting rod is screwed with the upper end of the automobile-used spark plug (2); the insulating rubber tube (4) is sleeved at the lower middle part of the center conducting rod (3); and the insulation tube (5) are sleeved at the upper parts of the center conducting rod (3) and the insulating rubbertube (4), and is fixed at the inner upper part of the housing (1). The spark plug for the combined-type gas engine has the advantages of simple structure and low manufacturing cost, and the head partof the spark plug can be directly replaced with a common automobile-used spark plug, so that much cost can be saved for a gas engine user, and the maintenance period can be shortened.
Description
Technical field
The utility model relates to a kind of spark plug, particularly a kind of separable spark plug that is used for gas internal-combustion engine.
Background technology
The spark plug of gas internal-combustion engine in use for some time, must change new product, the source of damage mostly is the terminal electrode ablation or inner open circuit causes, and at present, the spark plug that is used for gas internal-combustion engine is commonly monolithic construction, discarded spark plug totally all will be abandoned, can not reuse, caused very big waste, and because of the most dependence on import of the parts such as spark plug of China gas internal-combustion engine user replacing, replacement cost is very high, and this has also increased unnecessary financial burden for domestic gas internal-combustion engine user.
The utility model content
Technical problem to be solved in the utility model is: a kind of sparking plug for combined type gas internal combustion engine that reuses is provided.
Technical solution of the present utility model is: it comprises shell, automobile-used spark plug, central conductor leader, insulation rubber tube and insulated tube, described shell is last, the lower end is fixed with respectively, the pipe body of lower contact, shell has side window near the sidewall of lower contact, lower contact is provided with internal thread, automobile-used spark plug bottom is with sealing gasket and is tightened on the internal thread of lower contact in shell, the central conductor leader upper end has the bottle opener groove, lower end and automobile-used spark plug upper end are spirally connected, insulation rubber tube is enclosed within the lower middle portion of central conductor leader, and insulative is on the top of central conductor leader and insulation rubber tube and be fixed on the shell internal upper part.
Technique effect of the present utility model is: it has advantage simple in structure, that cost is low, and its head can directly be changed with common automobile-used spark plug, can be the gas internal-combustion engine user and saves great amount of cost and shorten maintenance period.
Description of drawings
Accompanying drawing is that structural representation cuts open in office of the present utility model.
Embodiment
As shown in drawings, the sparking plug for combined type gas internal combustion engine of present embodiment, comprise shell 1, automobile-used spark plug 2, central conductor leader 3, insulation rubber tube 4 and insulated tube 5, described shell 1 is last, the lower end is fixed with respectively, lower contact 6,7 pipe body, shell 1 has side window 8 near the sidewall of lower contact 7, top connection 6 is provided with external screw thread, in lower contact 7 is provided with, external screw thread, automobile-used spark plug 2 bottoms are with sealing gasket 9 and are tightened on the internal thread of lower contact 7 in shell 1, its central electrode 10 and grounding electrode 11 stretch out lower contact 7, central conductor leader 3 upper ends have bottle opener groove 12, the screw rod 13 of lower end and automobile-used spark plug 2 upper ends is spirally connected, insulation rubber tube 4 is enclosed within the lower middle portion of central conductor leader 3, and insulated tube 5 is a porcelain tube, and insulated tube 5 is enclosed within the top of central conductor leader 3 and insulation rubber tube 4 and is fixed on shell 1 internal upper part.
It is fixing that 1 on described insulated tube 5 and shell are provided with location rubber ring 14, also can adopt to make insulated tube 5 be fixed on shell 1 internal upper part as other fixed forms such as locating shoulders not go here and there.
Be provided with spacing shoulder 15 in the described insulated tube 5, insulation rubber tube 4 upper ends are spacing by spacing shoulder 15.
The automobile-used spark plug 2 of present embodiment adopts the long-neck spark plug, and except that automobile-used spark plug 2, remaining part is all reusable, when descending appears in service behaviour, needn't abandon whole assembly, only needs that automobile-used spark plug 2 is screwed off replacing and gets final product.This product contour dimension is all measure-alike with original imported product, easy to install, but direct substitution.Less because of the resistance of automobile-used spark plug 2 central electrodes 10, the ignition energy during work is higher, make combustion mixture burning rate comparatively fast, also more abundant, so also have obvious energy-saving effect.Because its one-time investment is just less than imported product, what add each replacing just is worth 6～7 yuans automobile-used spark plug 2, and therefore, release of this product and application just will reduce the expense that the user is paid greatly on this accessory; The application of this product, with having avoided a large amount of productions of other parts except that automobile-used spark plug 2, avoided the waste of the valuable raw material and the energy, simultaneously, its application also will be broken the situation that the gas engine spark plug can only rely on import, for country saves because of buying the required foreign exchange spending of imported product.We can say the present technique product except that having good technical performance and economy, also have good environment and social benefit.
