Description

Technical Field

[0001] The utility model relates to the technical field of oil pipes, in particular to a leak-proof automobile oil pipe assembly. Background Art

[0002] The gasoline pipe is an automobile accessory. When the car is working, it needs to provide oil to the driving mechanism. In the process of oil transportation, the corresponding automobile oil pipe is needed;

[0003] In actual use, the existing automobile oil pipes have a certain length, so they need to be connected with multiple pipes. In order to avoid leakage during the connection process, the two oil pipe ends are often fixed with bolts, and a sealing gasket is adapted at the connection between the two oil pipe ends to achieve compression sealing. However, the sealing gasket has an exposed part, and after a long time, the sealing gasket is damaged, resulting in oil leakage, so the sealing effect of directly using the sealing gasket is poor. Therefore, we propose a leak-proof automobile oil pipe assembly. Utility Model Content

[0004] The utility model aims to provide a leak-proof automobile oil pipe assembly, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a leak-proof automobile oil pipe assembly, comprising a first pipe and a second pipe, the second pipe being inserted into a sleeve, the second pipe being integrally formed with an end plate at one end corresponding to the sleeve, a connecting block being fixed to the outer wall of one end of the first pipe, the outer wall of the connecting block being provided with an external thread, the inner wall of the sleeve being provided with an internal thread, the internal thread and the external thread being threadably engaged, a first groove being provided on one side wall of the connecting block, a sealing rubber ring being installed in the first groove, a second groove being provided on the outer wall of the end plate corresponding to the sealing rubber ring, and the sealing rubber ring being pressed tightly in the first groove and the second groove.

[0006] By adopting the above technical solution, in actual use, the connection block is meshed with the sleeve thread by the thread, and the connection block and the end plate are fit together. At this time, the sealing rubber ring can be pressed by the first groove and the second groove to achieve sealing. The first groove and the second groove have a high degree of fit with the sealing rubber ring, which can improve the sealing effect. At the same time, the sealing rubber ring is protected by the sleeve to avoid exposure and extend its service life.

[0007] As a preferred embodiment of the utility model, a second rubber ring is fixed to the inner wall of the sealing rubber ring, and a side wall of the connecting block and a side wall of the end plate are both provided with accommodating grooves, and the two side walls of the second rubber ring are respectively placed in the accommodating grooves on both sides.

[0008] By adopting the above technical solution, when oil leaks out from the gap between the first pipe and the second pipe, the oil will act on the inner angle of the second rubber ring, so that the pressure of the oil pushes the two side walls of the second rubber ring to fit tightly against the corresponding inner wall of the receiving groove, thereby further improving the sealing effect and preventing continuous leakage of oil.

[0009] As a preferred embodiment of the utility model, a sealing gasket is fixed with glue to one side wall of the end plate corresponding to the inner cavity end face of the sleeve.

[0010] By adopting the above technical solution and setting the sealing gasket, the joint between the end plate and the sleeve can be sealed, further improving the sealing effect.

[0011] As a preferred implementation of the present invention, a limiting groove is provided at one end of the connecting block away from the end plate.

[0012] By adopting the above technical solution, when the sleeve is rotated, the connecting block can be stabilized by inserting the workpiece into the limiting groove, thereby facilitating disassembly and assembly.

[0013] As a preferred embodiment of the utility model, the outer wall of the sleeve is provided with a hexagonal groove.

[0014] By adopting the above technical solution, the setting of the hexagonal groove makes it convenient to use a hexagonal wrench to operate during disassembly, making the operation labor-saving and convenient.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The technical solution of the present application is a leakproof automobile oil pipe assembly, which achieves docking of a first pipe and a second pipe by meshing the external thread of a connecting block with the internal thread of a sleeve, and can compress the sealing rubber ring during the docking process, and the first groove and the second groove have a high degree of fit with the sealing rubber ring, thereby improving the sealing effect, and at the same time, the sealing rubber ring is protected by the sleeve to avoid being exposed, thereby extending the service life;

[0017] A second rubber ring is fixed on the inner wall of the sealing rubber ring, and the cross-section of the second rubber ring is triangular. When oil leaks out from the gap between the first pipe and the second pipe, the oil acts on the inner angle of the second rubber ring. The pressure of the oil pushes the two side walls of the second rubber ring to fit tightly against the corresponding inner wall of the receiving groove, thereby further improving the sealing effect and preventing continuous leakage of oil.

[0028] In actual use, the connection block 11 is threadedly engaged with the sleeve 3, and the connection block 11 and the end plate 21 are fitted together. At this time, the sealing rubber ring 14 can be pressed by the first groove 13 and the second groove 22, so as to achieve sealing. The first groove 13 and the second groove 22 have a high degree of fit with the sealing rubber ring 14, so as to improve the sealing effect. At the same time, the sealing rubber ring 14 is protected by the sleeve 3 to avoid being exposed, thereby extending the service life.

[0029] Furthermore, the outer wall of the sleeve 3 is provided with an inner hexagonal groove, and the setting of the inner hexagonal groove makes it convenient to operate with the aid of a hexagonal wrench during disassembly, making the operation labor-saving and convenient;

[0030] Furthermore, a limiting groove is provided at one end of the connection block 11 away from the end plate 21, so that when the sleeve 3 is rotated, the connection block 11 can be stabilized by inserting a workpiece into the limiting groove, thereby facilitating disassembly and assembly;

[0031] It is worth mentioning that a sealing gasket is fixed to one side wall of the inner cavity end face of the end plate 21 corresponding to the sleeve 3. The setting of the sealing gasket can seal the joint between the end plate 21 and the sleeve 3, further improving the sealing effect.

[0032] like Figure 1 and 3 4; a second rubber ring 15 is fixed to the inner wall of the sealing rubber ring 14, and a side wall of the connecting block 11 and a side wall of the end plate 21 are provided with a receiving groove, and the two side walls of the second rubber ring 15 are respectively placed in the receiving grooves on both sides, so that when oil leaks out from the gap between the first pipe 1 and the second pipe 2, the oil will act on the inner angle of the second rubber ring 15, so that the pressure of the oil pushes the two side walls of the second rubber ring 15 to fit tightly against the corresponding inner wall of the receiving groove, thereby further improving the sealing effect and preventing continuous leakage of oil.

[0033] The implementation principle of the leak-proof automobile oil pipe assembly of the present application is as follows: in actual use, the connection block 11 is threadedly engaged with the sleeve 3, and the connection block 11 and the end plate 21 are fitted together.
