Abstract
The utility model discloses a location structure is screwed up to automobile engine spark plug, including the spark plug and screwing up the sleeve on the spark plug, the sleeve front portion is established the spark plug and is connected the plum blossom, and the insulator surface of spark plug is overlapped in proper order to have and is connected the muffjoint plum blossom that the plum blossom cooperation was screwed up with the spark plug, spark plug flange and seal gasket, and the extension section is established to connection plum blossom front end, and it has positioning groove to extend interior division of section, and spark plug flange card is in positioning groove. The utility model discloses an add the contact length that the extension section prolongs sleeve and spark plug at the twelve point socket front end, and realize the axial positioning of spark plug in the sleeve through setting up positioning groove, clearance when making the spark plug screw up between sleeve and the spark plug reduces, the spark plug is difficult in the sleeve incline to be taken place or rocks, and then the insulator of having avoided sleeve and spark plug contacts, make that the spark plug no longer receives lateral shear power among the tightening process, finally solve in the easy problem that cracks of damaging of the insulator of spark plug in the twinkling of an eye of screwing up the end.
Description
Technical field
This utility model is related to engine components, in particular to a kind of automobile engine spark plug screwed in place structure.
Background technology
Jitter phenomenon in electromotor when rapidly loading during offline front bench test, it is obvious that moment of torsion in load
Beat, preliminary judgement is that high engine speeds ignition energy is inadequate.Find that insulator has crackle when disassembling spark plug and checking, thus
Know that spark plug insulator crackle is the reason causes electromotor to shake.Therefore, how to avoid spark plug insulator that crackle occurs just to become
Technical problem urgently to be resolved hurrily.
Content of the invention
The purpose of this utility model seeks to provide a kind of automobile engine spark plug screwed in place structure, and this structure reduces
Gap between spark plug and sleeve, it is to avoid spark plug cracking phenomena.
For achieving the above object, the technical solution adopted in the utility model is: a kind of automobile engine spark plug is tightened fixed
Bit architecture, including spark plug and the sleeve being tightened on described spark plug, described sleeve front portion is provided with spark plug and connects Flos Mume, institute
The insulator surface stating spark plug is cased with being connected the sleeve connection Flos Mume that Flos Mume cooperation is tightened, spark inserting method with described spark plug successively
Orchid and gasket seal, described spark plug connects Flos Mume front end and is provided with extension, has detent, described fire in described extension
Inserting method orchid is stuck in described detent flower.
The version of the sleeve connection Flos Mume part contact of middle sleeve and spark plug compared to existing technology, this utility model
By setting up extension come the contact length of lengthening sleeve and spark plug in coupling box front end, and by arrange detent
Realize axially position in sleeve for the spark plug, and then when spark plug is tightened, the gap between sleeve and spark plug reduce,
Spark plug is not susceptible to deflection in sleeve or rocks, and then avoids sleeve and contact so that tightening with the insulator of spark plug
In journey, spark plug is no longer influenced by lateral shearing force, finally solves the moment spark plug insulator tightening end and is easily damaged generation
The problem of crackle.Sleeve of the present utility model, when tightening spark plug, can protect spark plug intact nothing while ensureing moment
Damage, and then ensure that engine assembly matching requirements.
Further, described extension extends to described gasket seal.
Further, described extension inner surface is shiny surface, and described detent is to be opened in table in described extension
The annular groove in face.
Further, described extension radical length is 6～12mm.
Further, described detent radical length is 1～3mm.
Brief description
Fig. 1 is a kind of structural representation of automobile engine spark plug screwed in place structure.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, is easy to more clearly understand that this practicality is new
Type, but they do not constitute restriction to this utility model.
As shown in figure 1, a kind of automobile engine spark plug screwed in place structure, including spark plug 1 be tightened in described fire
Flower sleeve 2 beyond the Great Wall, described sleeve 2 front portion is provided with spark plug and connects Flos Mume 2-1, and it is sleeve 12 that this spark plug connects Flos Mume 2-1
Flower, the insulator surface of described spark plug 1 is cased with being connected the sleeve connection Flos Mume that Flos Mume 2-1 cooperation is tightened with described spark plug successively
1-1, this sleeve connection Flos Mume 1-1 are spark plug 12 flower, spark plug flange 1-2 and gasket seal 1-3, and spark plug connects Flos Mume
2-1 front end is provided with extension 2-2, and this extension segment length 12mm, but can not handle completely so as to extend to gasket seal 1-3 part
Gasket seal 1-3 includes, and prevents spark plug in rundown process from tightening not phenomenon on earth, and extension 2-2 inner surface is light
Sliding surface, this inner surface of extension 2-2 has the detent 2-21 of ringwise groove-like, detent 2-21 radical length
For 2mm, spark plug flange 1-2 is stuck in this detent 2-21.
In addition, the rear end of sleeve 2 has the square hole 2-3 for connecting spanner, during processing, this square hole 2-3 and fire need to be ensured
Hua Sai connects the axiality of Flos Mume 2-1, and after machining, the spark plug of sleeve connects Flos Mume 2-1 and is enclosed within spark plug, square hole 2-
3 are connected with spanner.
This spark plug screwed in place structure successfully uses on eb electromotor, since use, has eliminated spark plug and set
The gap of cylinder, thoroughly solves the phenomenon that spark plug is broken, effectively improves the quality of engine assembly, under improve once
Line qualification rate；Meanwhile, for avoiding similar problem to repeat, factory carries out generally investigating wind to the spark-plug socket of all series
Danger, because this sleeve using effect is good, the sleeve of this structure is also applied to ep6/ep8tu5jp4/tu3af/ec5/
The electromotor of the series such as ec8/ew10/ew12, the risk that prevention spark plug is broken, at the same time it can also extend to similar tightening
On the sleeve requiring.
