Description

Technical Field

[0001] This utility model relates to the field of pipeline installation, and more specifically, to a quick-connect pipe fitting device. Background Technology

[0002] The automotive air conditioning system is used to adjust and control the temperature, humidity, air cleanliness, and airflow inside a car cabin to maintain optimal conditions, providing a comfortable riding environment for passengers, reducing travel fatigue, and creating favorable working conditions for the driver.

[0003] Unlike household air conditioners, car air conditioners don't usually have enough space for pipe layout during installation. Cars have relatively little space, so the pipes often involve bends. To facilitate these bends, flexible hoses are typically used during installation. While this flexibility makes installation easier, it also reduces stability. Since cars are constantly in motion, flexible hoses must be secured with a device, which increases installation time and costs.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0023] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0024] Please see Figure 1-7 According to an embodiment of the present invention, a quick-connect pipe device includes an outer sleeve 1. A ball joint 2 is installed inside one end of the outer sleeve 1. A first pipe 3 is fixedly installed at the end of the outer sleeve 1 away from the ball joint 2. A second pipe 4 is fixedly connected to the end of the ball joint 2 away from the outer sleeve 1. The ball joint 2 can be rotated and adjusted at a certain angle relative to the outer sleeve 1, thereby allowing the second pipe 4 to rotate at a certain angle relative to the first pipe 3. The ball joint 2 includes a connecting pipe 201 arranged in a straight line, one end of which... The end is integrally provided with a spherical head 203, and the end of the connecting pipe 201 away from the spherical head 203 is integrally provided with a connecting sleeve 202. The connecting pipe 201, the connecting sleeve 202 and the spherical head 203 are internally connected. The spherical head 203 is movably disposed inside the outer sleeve 1. One end of the second pipe 4 is fixedly installed in the connecting sleeve 202. The spherical head 203 can rotate at a certain angle inside the outer sleeve 1, thereby meeting certain assembly requirements. Compared with the use of ordinary hoses, it saves time and reduces the cost of processing steps, tooling and labor.

[0025] The outer sleeve 1 is internally fitted with an inner liner 6 and an outer liner 7, which are positioned opposite each other. A spherical head 203 is located between the inner liner 6 and the outer liner 7, and the inner wall of the inner liner 6 and the outer liner 7 facing the spherical head 203 is in a sealing sliding connection with the outer wall of the spherical head 203. The arrangement of the inner liner 6 and the outer liner 7 ensures the airtightness of the spherical head 203 inside the outer sleeve 1, ensuring both communication between the spherical head 203 and the interior of the outer sleeve 1 while maintaining a tight seal.

[0026] The outer sleeve 1 is also provided with a sealing ring 5, which is located between the inner liner 6 and the outer liner 7, and is fitted over the outside of the spherical head 203. The sealing ring 5 can further increase the sealing performance of the spherical head 203 when installed inside the outer sleeve 1.

[0027] The inner wall of the outer sleeve 1 is provided with an annular sealing groove 101, and the sealing ring 5 is disposed in the sealing groove 101. The sealing groove 101 can provide a stable space for the assembly of the sealing ring 5.

[0028] A first retaining edge 102 is integrally formed on the inner wall of the outer sleeve 1 facing the second pipe 4, and one end of the outer gasket 7 is tightly abutted against the first retaining edge 102. The first retaining edge 102 provides a stable platform for the stable installation of the outer gasket 7. A retaining ring 8 is installed inside the end of the outer sleeve 1 away from the first pipe 3. The retaining ring 8 can block the outer gasket 7 and ensure the stable assembly of the outer gasket 7.

[0029] The outer sleeve 1 also has a second retaining edge 103 located near the first pipe 3. The inner liner 6 is assembled on the end of the second retaining edge 103 away from the first pipe 3. The second retaining edge 103 provides a platform for the assembly of the inner liner 6. In actual assembly, the inner liner 6 is first tightly pressed against the second retaining edge 103, then the sealing ring 5 is placed in the sealing groove 101, and then the spherical head 203 of the spherical connector 2 is inserted so that the outer wall of the spherical head 203 is tightly pressed against the inner wall of the inner liner 6. Then the outer liner 7 is placed into the outer sleeve 1 through the outside of the connecting pipe 201 until the end of the outer liner 7 is tightly pressed against the first retaining edge 102. Finally, the retaining ring 8 is assembled into the outer sleeve 1 and the outer liner 7 is locked.

[0030] An annular groove 104 is provided on the inner wall of the outer sleeve 1 near the second pipe 4. The annular groove 104 is used to assemble the retaining ring 8.

[0031] The outer liner 7 has a notch 71 on its inner wall and an opening 72 on its outer liner 7. This design allows the inner diameter of the outer liner 7 to be reduced by external force, making it easier to assemble into the outer sleeve 1.

[0032] Through the above-described solution of this utility model, the structure of this utility model is simple and reasonable, and it is quick and convenient to use and assemble. The spherical head 203 can rotate at a certain angle inside the outer sleeve 1, thereby meeting certain assembly requirements. Compared with the use of ordinary hoses, it saves time and reduces the cost of processing steps, tooling, and labor.
