Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a formula oil pipe inserts soon for commercial car hydraulic system, includes high pressure fuel pipe 3, the outside cover of 3 one ends of high pressure fuel pipe is equipped with sleeve pipe 2, the inside cover of 3 one ends of high pressure fuel pipe is equipped with connects body 1 soon, it is fixed through the mode of riveting between joint body 1, sleeve pipe 2, the high pressure fuel pipe 3 soon, set up two loop configuration's notch on the one end outer wall of connecting body 1 soon, two all overlap in the notch and be equipped with sealing washer 4.
In order to facilitate the connection of the quick-connect joint body 1, a protruding portion 11 and a groove 12 are further arranged on the quick-connect joint body 1, the protruding portion 11 is of a conical structure, and the groove 12 is of an annular groove-shaped structure.
In order to enable the sleeve 2 to be connected with the quick-connection joint body 1 in a fastening and clamping manner during riveting, the diameter of the part, located inside the sleeve 2, of the quick-connection joint body 1 is smaller than that of the part, located outside the quick-connection joint body 1, the part, extending into the inside of the sleeve 2, of the quick-connection joint body 1 is further provided with a clamping convex part 13 in an annular structure, and the sleeve 2 is clamped on the clamping convex part 13 through riveting.
In order to enable the high-pressure oil pipe 3 to be connected with the quick-connection joint body 1 in a riveting and fastening manner, clamping grooves which are arranged at equal intervals and are of an annular structure are formed in the part, extending into the high-pressure oil pipe 3, of the quick-connection joint body 1, and the inner wall of the high-pressure oil pipe 3 is clamped in the clamping grooves when the quick-connection joint body 1, the sleeve 2 and the high-pressure oil pipe 3 are fixed in a riveting and fastening manner.
