Abstract
The utility model discloses a car engine oil pipe. The car engine oil pipe comprises an oil pipe body (1) and pipe connectors connected at the two ends of the oil pipe body (1), wherein the end faces of both the pipe connectors at the two ends of the oil pipe body (1) are sealed. By the adoption of the structure, end face sealing structures which are of a sealing ring structure are arranged between the oil pipe body and the pipe connectors, and therefore the sealing performance of the oil pipe is better. Besides, when the connectors are abraded after being used for a long time, the connectors are demounted, only sealing rings in the connectors need to be replaced, the whole pipe connectors do not need to be replaced, and therefore the using cost is reduced.
Description
Technical field
The utility model relates to the hydraulic tube piece technical field, specifically is a kind of automobile engine oil pipe.
Background technique
Automobile engine system is the key components and parts of automobile, wherein uses various oil pipes.The automobile engine oil pipe of prior art comprises the connecting head at oil pipe body and two ends thereof, and connecting head commonly used is that two ends all adopt the cutting ferrule of snapping to seal.But there is following shortcoming in the automobile engine oil pipe of this structure:
1) pipe joint that seals owing to the cutting ferrule with snapping, the gap is larger, and therefore, sealing is poor;
2) in addition, when joint has wearing and tearing after long-time the use, therefore need to change, what still change is whole joint, like this, increases user cost.
The model utility content
Technical problem to be solved in the utility model is, a kind of good airproof performance is provided, and the low automobile engine oil pipe of user cost.
For solving the problems of the technologies described above, the automobile engine oil pipe that the utility model provides comprises oil pipe body and the pipe joint that is connected to oil pipe body two ends, and the pipe joint at described oil pipe body two ends is the pipe joint of end face seal.
The pipe joint of described end face seal refers to that it comprises joint, adapter sleeve and seal ring, and an end of described joint is the threaded end that is connected with other component, and the other end close-fitting is in the oil pipe body; One end close-fitting of adapter sleeve is originally external at oil pipe, and the other end is pushed against on the joint; Have seal ring in the adapter sleeve and between the end face of oil pipe body, seal ring is socketed on the joint.
Have many uniform and be arranged in parallel first ring connected in stars on the outer peripheral surface of the end that described joint is connected with the oil pipe body, have many second uniform and be arranged in parallel annular grooves on the inner peripheral wall of the end that adapter sleeve is connected with the oil pipe body.
Described joint middle part has the shaft shoulder, and the oil pipe body is pushed against the step surface place of the shaft shoulder, and seal ring is socketed on the shaft shoulder.
The periphery wall of the intermediate portion of described joint is outer-hexagonal shape sidewall.
After adopting above structure, the utility model compared with prior art has the following advantages:
1) owing between oil pipe body and pipe joint, be provided with the end face seal structure of ring structure, therefore, makes the better tightness of oil pipe;
2) in addition, when joint after the long-time wearing and tearing of using, only joint need to be pulled down a seal ring of changing the inside and get final product, therefore, need not to change whole pipe joint, thereby the reduction user cost;
3) setting of the second annular groove in the setting of first ring connected in star and the adapter sleeve on the joint, this physical efficiency of oil pipe that nonmetallic material are made is squeezed in the annular groove, therefore, makes connection more firm on the one hand, also increases on the other hand sealing;
4) setting of the shaft shoulder makes a position-limiting action that is equipped with of oil pipe body, makes assembling more quick and simple;
5) structure of joint middle part outer-hexagonal shape perisporium is in order to operate at hexagon wrench easy for installation.
Description of drawings
Fig. 1 is the structural representation of the utility model automobile engine oil pipe.
Fig. 2 is the sectional structure schematic representation of the utility model automobile engine oil pipe.
Wherein: 1, oil pipe body; 2, joint; 2.1, the first ring connected in star; 2.2, the shaft shoulder; 3, seal ring; 4, adapter sleeve; 4.1, the second annular groove.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in more detail.
By the structural representation of the utility model automobile engine oil pipe illustrated in figures 1 and 2 as can be known, it comprises oil pipe body 1 and is connected to the pipe joint at oil pipe body 1 two ends that the pipe joint at described oil pipe body 1 two ends is the pipe joint of end face seal.
The pipe joint of described end face seal refers to that it comprises joint 2, adapter sleeve 4 and seal ring 3, and an end of described joint 2 is the threaded end that is connected with other component, and the other end close-fitting is in oil pipe body 1.One end close-fitting of adapter sleeve 4 is outside oil pipe body 1, and the other end is pushed against on the joint 2.Have seal ring 3 in the adapter sleeve 4 and between the end face of oil pipe body 1, seal ring 3 is socketed on the joint 2.
Have many uniform and be arranged in parallel first ring connected in stars 2.1 on the outer peripheral surface of the end that described joint 2 is connected with oil pipe body 1, have many second uniform and be arranged in parallel annular grooves 4.1 on the inner peripheral wall of the end that adapter sleeve 4 is connected with oil pipe body 1.
Described joint 2 middle parts have the shaft shoulder 2.2, and oil pipe body 1 is pushed against the step surface place of the shaft shoulder 2.2, and seal ring 3 is socketed on the shaft shoulder 2.2.
The periphery wall of the intermediate portion of described joint 2 is outer-hexagonal shape sidewall.
