Description

Technical Field

[0001] This utility model relates to the field of oil pipe joint technology, specifically a novel aluminum alloy oil pipe joint. Background Technology

[0002] Aluminum alloy tubing fittings are components used to connect tubing. They are made of aluminum alloy, which is lightweight and easier to handle and install compared to tubing fittings made of stainless steel or carbon steel. This reduces labor intensity and improves work efficiency.

[0003] For example, a new type of aluminum alloy automotive oil pipe connector with announcement number "CN211599863U" allows for the quick and easy installation and disassembly of the middle connector pipe, outer connector pipe, and inner connector pipe by rotating the handle and transmitting a transmission. This simplifies assembly and disassembly, making it convenient and time-saving. However, since the oil pipe is typically installed in a confined space (such as the engine compartment), disassembling or assembling the first connecting pipe requires rotating two handles, which takes a considerable amount of time. Furthermore, the oil pipe connector relies on a first and second annular sealing gasket for sealing; over time, this sealing gasket is prone to aging and leakage. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that oil pipes are usually installed in confined spaces (such as engine compartments), and when it is necessary to disassemble or assemble the first connecting pipe, it is necessary to turn two handles, which takes a long time to complete the disassembly or assembly work. At the same time, the oil pipe joint is sealed by the first annular sealing gasket and the second annular sealing gasket. After long-term use, it is prone to aging and leakage. Therefore, a new type of aluminum alloy oil pipe joint is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel aluminum alloy oil pipe joint is designed, comprising a first connecting pipe and a second connecting pipe, the inner sides of the first connecting pipe and the second connecting pipe being in contact with each other, the second connecting pipe having a sealing structure inside, and a connecting structure on the outer side of the second connecting pipe, the connecting structure including a connector pipe, the connector pipe being rotatably connected to the second connecting pipe through a sealing bearing, and the inner wall of the connector pipe being threadedly connected to the first connecting pipe.

[0006] Preferably, the outer wall of the connector tube is fixedly connected with multiple protrusions.

[0007] Preferably, the sealing structure includes a slot, a first elastic sealing ring, a second elastic sealing ring, and a third elastic sealing ring. The first, second, and third elastic sealing rings are respectively abutted against the elastic ring and the first connecting pipe on both sides. The right side of the elastic ring is abutted against the second connecting pipe. The inner walls of the elastic ring, the first elastic sealing ring, the second elastic sealing ring, and the third elastic sealing ring are all sleeved with the first connecting pipe.

[0008] Preferably, the right side of the first connecting tube is inserted into the slot.

[0009] Preferably, the slot is machined on the left side of the inner wall of the second connecting tube.

[0010] The novel aluminum alloy oil pipe connector proposed in this utility model has the following advantages: by cooperating with the second connecting pipe and the connecting structure, the first connecting pipe and the connector pipe are aligned, and multiple protrusions are rotated to tighten the connector pipe on the outside of the first connecting pipe. When installing and disassembling the first connecting pipe, only the connector pipe needs to be rotated, which can save space during operation and complete the disassembly and assembly work in a short time.

[0011] Through the cooperation of the second connecting pipe and the sealing structure, multiple elastic rings are placed into the slots respectively. Then, the first, second, and third elastic sealing rings are placed to the left of the corresponding elastic rings. When the connector is tightened on the outside of the first connecting pipe, the first connecting pipe is inserted into the slot. At this time, the first, second, and third elastic sealing rings are pressed against the elastic rings and the first connecting pipe on both sides. When the first, second, and third elastic sealing rings age, the elastic rings can provide additional elastic pressure to ensure that the first, second, and third elastic sealing rings are always pressed against the first connecting pipe, reducing the possibility of leakage.

[0014] The present invention will be further described below with reference to the accompanying drawings: See attached document Figure 1-6 In this embodiment, a novel aluminum alloy oil pipe joint includes a first connecting pipe 1 and a second connecting pipe 3. The inner sides of the first connecting pipe 1 and the second connecting pipe 3 are in contact. The second connecting pipe 3 has a sealing structure 2 inside and a connecting structure 4 on the outside. The connecting structure 4 includes a connector pipe 402. The connector pipe 402 is rotatably connected to the second connecting pipe 3 through a sealing bearing. The inner wall of the connector pipe 402 is threaded to the first connecting pipe 1. The outer wall of the connector pipe 402 is fixedly connected with multiple protrusions 401, which can increase the friction. Align the first connecting pipe 1 with the connector pipe 402, rotate the multiple protrusions 401, thereby tightening the connector pipe 402 on the outside of the first connecting pipe. When installing and disassembling the first connecting pipe, only the connector pipe 402 needs to be rotated, which can save space during operation and complete the disassembly and assembly work in a short time. The sealing structure 2 includes a slot 205, a first elastic sealing ring 201, a second elastic sealing ring 202, and a third elastic sealing ring 203. The first elastic sealing ring 201, the second elastic sealing ring 202, and the third elastic sealing ring 203 are all made of fluororubber, which has excellent oil and solvent resistance and outstanding high temperature resistance. The first elastic sealing ring 201, the second elastic sealing ring 202, and the third elastic sealing ring 203 are respectively abutted against the elastic ring 204 and the first connecting pipe 1 on both sides. The right side of the elastic ring 204 is abutted against the second connecting pipe 3. The size of the multiple elastic rods 204 corresponds to the first elastic sealing ring 201, the second elastic sealing ring 202, and the third elastic sealing ring 203. The inner walls of the elastic ring 204, the first elastic sealing ring 201, the second elastic sealing ring 202, and the third elastic sealing ring 203 are all sleeved with the first connecting pipe 1. The right side of the first connecting pipe 1 is inserted into the slot 205. The slot 205 is machined on the left side of the inner wall of the second connecting pipe 3. When the first elastic sealing ring 201, the second elastic sealing ring 202, and the third elastic sealing ring 203 age, the elastic ring 204 can provide additional elastic pressure to ensure that the first elastic sealing ring 201, the second elastic sealing ring 202, and the third elastic sealing ring 203 are always tightly pressed against the first connecting pipe 1, reducing the occurrence of leakage.

[0015] Working principle: When using the new aluminum alloy oil pipe fittings: The operator places multiple elastic rings 204 into slots 205 respectively, and then places the first elastic sealing ring 201, the second elastic sealing ring 202 and the third elastic sealing ring 203 to the left of the corresponding elastic rings 204. The operator then aligns the first connecting tube 1 with the connector tube 402 and rotates multiple protrusions 401, thereby tightening the connector tube 402 on the outside of the first connecting tube 1. When installing and removing the first connecting tube 1, only the connector tube 402 needs to be rotated, which can save space during operation and can complete the disassembly and assembly work in a short time. When the connector tube 402 is tightened to the outside of the first connecting tube 1, the first connecting tube 1 is inserted into the slot 205. At this time, the first elastic sealing ring 201, the second elastic sealing ring 202, and the third elastic sealing ring 203 are respectively pressed against the elastic ring 204 and the first connecting tube 1. When the first elastic sealing ring 201, the second elastic sealing ring 202, and the third elastic sealing ring 203 age, the elastic ring 204 can provide additional elastic pressure to keep the first elastic sealing ring 201, the second elastic sealing ring 202, and the third elastic sealing ring 203 pressed against the first connecting tube 1, reducing the possibility of leakage.
