Abstract
The utility model discloses an oil level gauge for a diesel engine. The oil level gauge for the diesel engine comprises a plug and an oil dipstick tube sleeve matched with the plug. An O-shaped seal ring is arranged on the plug and the O-shaped seal ring is matched with the oil dipstick tube sleeve. The plug is provided with a circular bulge. The inner surface of the oil dipstick tube sleeve is provided with a circular groove corresponding to the circular bulge. The circular bulge on the plug is clamped into the circular groove on the oil dipstick tube sleeve to firmly match the plug with the oil dipstick tube sleeve, so that the falling out of the plug from the oil dipstick tube sleeve under harsh working conditions will be prevented and further sealing is achieved. An elongated slot is formed on the oil dipstick tube sleeve, so that the plug will be deformed under squash when pulled out and is smoothly pulled out with little blocking. The oil level gauge for the diesel engine is simple in structure and improves the performance of the oil level gauge.
Description
Technical field
The utility model relates to a kind of use for diesel engine oil scale.
Background technique
The linkage structure of existing oil scale plug and dipstick pipe box is simple, O RunddichtringO is installed on plug, between plug and dipstick pipe box, only depend on O RunddichtringO to be tightly connected, there is no Anti-extrusion mechanism, under the severe condition of operating mode, cannot effectively prevent oil scale work in deviate from, probably machine oil is spilt, motor is because oil level is not enough, or the impurity such as a large amount of dusts, sandy soil are along with the interface of oil scale enters oil sump, the heavy wear such as scuffing of cylinder bore occurs, change watt, thus greatly shorten engine life or produce serious consequence.
The plug using is at present different with dipstick pipe box material, and plug is nylon, and dipstick pipe box is metal, and while expanding with heat and contract with cold, expansion coefficient is different, so the seal degree of O RunddichtringO can difference under Various Seasonal, is also to cause one of problem that oil scale easily deviates from.
Model utility content
The technical problems to be solved in the utility model is for above-mentioned defect, and a kind of use for diesel engine oil scale that can prevent that plug from coming off out from dipstick pipe box is provided.
In order to solve the problems of the technologies described above, the dipstick pipe box that the utility model comprises plug and coordinates with plug, the O RunddichtringO being sealed and matched with dipstick pipe box is installed on described plug, its structural feature is that described plug is provided with annular protrusion, and the internal surface of described dipstick pipe box is provided with the annular groove corresponding with annular protrusion.
Described oil dipstick tube puts and is provided with at least two microscler flutings.
Described fluting is arranged on the connecting end of plug and dipstick pipe box and extends upward from the diapire of annular groove.
Described annular protrusion is arranged on the top of O RunddichtringO.
Adopt the use for diesel engine oil scale of such scheme compared with prior art to have the following advantages: the annular protrusion on plug is snapped fitted in the annular groove that oil dipstick tube puts, plug is coordinated firmly with dipstick pipe box, can prevent that under the severe condition of operating mode, plug comes off out from dipstick pipe box, play again the effect of further sealing simultaneously; Oil dipstick tube puts the microscler fluting of setting, can make plug extrusion in plug process, thereby inserts smoothly and extract, and is difficult for occurring clamping stagnation.And the utility model is simple in structure, improved the performance of oil scale.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of plug;
Fig. 3 be in Fig. 1 A-A to sectional view.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, this use for diesel engine oil scale comprises plug 1 and the dipstick pipe box 2 coordinating with plug 1, dipstick pipe box 2 is tubular outer cover, the O RunddichtringO 3 being sealed and matched with dipstick pipe box 2 is installed on plug 1, plug 1 is provided with annular protrusion 4, and the internal surface of dipstick pipe box 2 is provided with the annular groove corresponding with annular protrusion 45.Dipstick pipe box 2 is provided with at least two microscler flutings 6, and in the present embodiment, microscler fluting 6 is preferably and arranges three.Fluting 6 is arranged on the connecting end of plug 1 and dipstick pipe box 2, and the diapire from annular groove 5 extends upward, slot and 6 annular groove 5 can be exposed, the annular protrusion 4 that makes to be installed in annular groove 5 exposes, thereby make the part extrusion in fluting 6 of annular protrusion 4 on plug 1, realize plug smoothly.Annular protrusion 4 is arranged on the top of O RunddichtringO 3.In the present embodiment, plug 1 and dipstick pipe box 2 all adopt nylon to make, and make plug 1 and dipstick pipe box 2 materials unified, and the coefficient expanding with heat and contract with cold is consistent, Various Seasonal temperature, and the dynamics of plug is basically identical, and reaches better sealing effect.
During installation, plug 1 is inserted in dipstick pipe box 2, the part extrusion of annular protrusion 4 in fluting 6, can insert very smoothly, O RunddichtringO 3 on plug 1 can make plug 1 and dipstick pipe box 2 closely cooperate and have seal action, the annular protrusion 4 of installing on plug 1 coordinates with annular groove 5 internal surfaces, can prevent that under bad working environments, plug 1 comes off out from dipstick pipe box 2, and play the effect of further sealing; During dismounting, plug 1 is extracted from dipstick pipe box 2, annular protrusion 4 departs from annular groove 5, and the part extrusion of annular protrusion 4 in fluting 6, can extract very smoothly.
The utility model is not limited to above-mentioned embodiment, and those skilled in the art, not departing under the prerequisite of spirit and scope of the present utility model, can do some changes and modification.Protection domain of the present utility model should be as the criterion with claim of the present utility model.
