Abstract
The invention relates to a sparking plug for a combined type gas internal combustion engine, which comprises a shell (1), an automotive sparking plug (2), a center conducting rod (3), an insulating hose (4) and an insulating pipe (5), wherein the upper end and the lower end of the shell (1) are fixed with an upper joint (6) and a lower joint (7), the side wall of the shell (1) close to the lower joint (7) is provided with a side window (8), the lower joint (7) is provided with internal threads, the automotive sparking plug (2) is screwed on the internal threads of the lower joint (7), the upper end of the center conducting rod (3) is provided with a screwdriver groove (12) while the lower end is in threaded connection with the upper end of the automotive sparking plug (2), the insulating hose (4) is sleeved on the middle-lower part of the center conducting rod (3), and the insulating pipe (5) is sleeved on the upper parts of the center conducting rod (3) and the insulating hose (4) and is fixed on the inner upper part of the shell (1). The sparking plug for the combined type gas internal combustion engine has the advantages of simple structure and low manufacturing cost, the head of the sparking plug can be directly replaced by a common automotive sparking plug, and the sparking plug can save significant cost and shorten the maintenance cycle for gas internal combustion engine users.
Description
Technical field
The present invention relates to a kind of spark plug, particularly a kind of separable spark plug that is used for gas internal-combustion engine.
Background technique
The spark plug of gas internal-combustion engine must be changed new product in use for some time, and mostly the source of damage is that terminal electrode is ablated or inner open circuit causes; And at present; The spark plug that is used for gas internal-combustion engine is commonly monolithic construction, and discarded spark plug totally all will be abandoned, and can not reuse; Caused very big waste; And because of the most dependence on import of component such as spark plug that China gas internal-combustion engine user changes, replacement cost is very high, and this has also increased unnecessary economic burden for domestic gas internal-combustion engine user.
Summary of the invention
Technical problem to be solved by this invention is: a kind of sparking plug for combined type gas internal combustion engine that reuses is provided.
Technical solution of the present invention is: it comprises shell, automobile-used spark plug, central conductor leader, insulation rubber tube and insulation tube; Said shell is the pipe body that upper and lower end is fixed with upper and lower joint respectively; Shell has side window near the sidewall of lower contact, and lower contact is provided with internal thread, and automobile-used spark plug bottom is with sealing gasket and in shell, is tightened on the internal thread of lower contact; The central conductor leader upper end has the bottle opener groove; Lower end and automobile-used spark plug upper end is spirally connected, and 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 invention is: it has advantage simple in structure, that cost is low, and its head can use common automobile-used spark plug directly to change, and can be the gas internal-combustion engine user and practices thrift great amount of cost and shorten maintenance period.
Description of drawings
Accompanying drawing is that structural representation cuts open in office of the present invention.
Embodiment
Shown in accompanying drawing; The sparking plug for combined type gas internal combustion engine of this mode of execution comprises shell 1, automobile-used spark plug 2, central conductor leader 3, insulation rubber tube 4 and insulation tube 5, and said shell 1 is fixed with the pipe body of upper and lower joint 6,7 respectively for upper and lower end; Shell 1 has side window 8 near the sidewall of lower contact 7; Upper connection 6 is provided with outside thread, and lower contact 7 is provided with internal and external screw thread, and automobile-used spark plug 2 bottoms are with sealing gasket 9 and in shell 1, are tightened on the internal thread of lower contact 7; Its centre electrode 10 and ground electrode 11 stretch out lower contact 7; Central conductor leader 3 upper ends have bottle opener groove 12, and the screw rod 13 of lower end and automobile-used spark plug 2 upper ends is spirally connected, and insulation rubber tube 4 is enclosed within the lower middle portion of central conductor leader 3; Insulation tube 5 is porcelain tube or other hard insulation, and insulation 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 said insulation tube 5 and shell are provided with location rubber ring 14, also can adopt to make insulation tube 5 be fixed on shell 1 internal upper part like other means of fixation such as locating shoulders not go here and there.
Be provided with spacing shoulder 15 in the said insulation tube 5, insulation rubber tube 4 upper ends are spacing by spacing shoulder 15.
The automobile-used spark plug 2 of this mode of execution adopts the long-neck spark plug; Except that automobile-used spark plug 2, remaining part is all reusable, when descending appears in service behaviour; Needn't abandon whole assembly, only need screw off automobile-used spark plug 2 from side window 8 replacings of shell 1 and get final product.This product overall sizes 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 centre electrodes 10, the ignition energy during work is higher, make inflammable mixture velocity of combustion 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 a large amount of productions of having avoided 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.
