Abstract
The utility model discloses an oil tube which comprises an oil tube body (1) and tube joints connected to the two ends of the oil tube body (1). The oil tube body (1) is a Teflon tube. The tube joints are connected to the two ends of the Teflon tube in a buckled mode. Each tube joint comprises a joint body (2), a sealing ring (4) and a fastening sleeve (3). One end of each joint body (2) is a connecting end which is provided with inner threads and connected with other parts. The other end of each joint body (2) is in close fit in the Teflon tube. One end of each fastening sleeve (3) is in close fit outside the Teflon tube. The other end of each fastening sleeve (3) is connected to each joint body (2) in a sleeved mode. Each sealing ring (4) is in close fit on each joint body (2) and located between each fastening sleeve (3) and the end face of the Teflon tube. After the structure is adopted, due to the adoption of the buckling structure, the Teflon tube and the tube joints are tightly connected together, therefore, the sealing performance is improved, and the connection firmness is reinforced.
Description
Technical field
The utility model relates to the hydraulic tube piece technical field, is specifically a kind of oil pipe.
Background technique
Oil pipe is part commonly used in various device and device, on motor car engine.The oil pipe of prior art normally is comprised of a sebific duct and the joint that is connected to sebific duct two ends, and joint is fixedly connected on sebific duct by clip usually.But there is following shortcoming in the oil pipe of this structure:
1) because the connection of clip is easy to looseningly even come off, therefore, connect very insecure, thereby affect the normal use of oil pipe;
2) in addition, need to use some special tools when clip is installed, assemble cumbersome.
The model utility content
Technical problem to be solved in the utility model is, provides a kind of and is connected firmly, thereby ensure normal the use, and simple oil pipe easy for installation.
For solving the problems of the technologies described above, the 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 described oil pipe body is teflon pipe, and pipe joint snaps onto the two ends of teflon pipe.
Described snapping refers to, it comprises joint body, seal ring and adapter sleeve, the connecting end with internal thread of an end of described joint body for being connected with other parts, and the other end close-fitting is in teflon pipe; One end close-fitting of adapter sleeve is outside teflon pipe, and the other end is socketed on joint body; The seal ring close-fitting is on joint body and between adapter sleeve and teflon pipe end face.
Described joint body has the first ring connected in star with being connected of teflon pipe on surface of contact, adapter sleeve has the second annular groove with being connected of teflon pipe on surface of contact.
The middle part of described joint body has the shaft shoulder, and the seal ring close-fitting is on the shaft shoulder, and the end face of teflon pipe is pushed against on the step surface of the shaft shoulder.
After adopting above structure, the utility model compared with prior art has the following advantages:
1) due to the structure that adopts snapping, teflon pipe is linked together tightly with pipe joint, therefore, namely improved sealability, strengthened again the soundness that connects;
2) in addition, above-mentioned structure need not to use special tool, and is easy to assembly, simple.
