Description

Technical Field

[0001] The utility model relates to the technical field of automobile cooling pipes, in particular to an automobile cooling pipe docking device. Background Art

[0002] Automobile cooling hose is a kind of connecting pipe widely used in automobile coolant circulation. It has the characteristics of light weight, excellent performance, high reliability and long service life. In actual use, the automobile cooling system requires rubber hose with convenient detachable connection.

[0003] The existing patent (publication number: CN220060964U) discloses an automobile cooling pipe docking device, including a docking joint and a cooling pipe, one end of the docking joint is equipped with a self-sealing tube, the end of the self-sealing tube away from the docking joint is connected to a circulation pipe, the end of the circulation pipe away from the self-sealing tube is connected to the cooling pipe, a self-sealing plunger is installed inside the self-sealing tube, the other end of the docking joint can be inserted into the docking joint two to connect the pipes, through the self-sealing plunger, after the docking joint is disassembled and the connecting rod loses the push of the top plate, the self-sealing plunger can be pushed from the circulation pipe to the self-sealing tube by the elastic force of the spring, and the self-sealing tube is sealed and closed by the self-sealing plunger, so that the docking joint can be closed to prevent the coolant remaining in the cooling pipe from flowing out of the docking joint after the docking joint is disassembled, thereby preventing other parts of the automobile from being contaminated.

[0004] The above patented technology can prevent the coolant remaining in the cooling pipe from flowing out of the docking joint after the docking joint is disassembled, thereby preventing contamination of other parts of the car. In actual use, when the two docking joints are connected, the connecting rod is used to push the self-sealing plunger from the self-sealing pipe to the flow pipe, so that the pipe becomes unobstructed, so that the coolant in the pipe can flow normally. However, the presence of the self-sealing plunger will affect the circulation of the coolant. Although both ends of the self-sealing plunger are tapered, it may still lead to a low circulation of the coolant, affecting use. Therefore, an automobile cooling pipe docking device is proposed.

[0023] Example 1:

[0024] Please refer to Figure 1-Figure 4The utility model provides a technical solution: a car cooling pipe docking device, including a first cooling pipe 1 and a second cooling pipe 2, a connecting tube 3 is provided at the middle end of the second cooling pipe 2, the inner surface of the first cooling pipe 1 is fixedly connected to a fixed disk 4, the outer surface of the fixed disk 4 is movably inserted with a push rod 5, the outer surface of the push rod 5 away from the fixed disk 4 is fixedly connected to a plug 6, the inner surface of the plug 6 is rotatably connected to a rotating disk 7, the outer surface of the plug 6 is provided with four first through holes 8 in a circumferential array, the outer surface of the rotating disk 7 is provided with four second through holes 9 arranged in a circumferential array, the inner surface of the second cooling pipe 2 is rotatably connected to a strip rod 12, the outer surface of the strip rod 12 is fixedly connected to a rectangular rod 13, the outer surface of the push rod 5 A rectangular groove 11 is opened. In this embodiment, the first cooling tube 1 and the second cooling tube 2 are spliced. When splicing, the rectangular rod 13 in the second cooling tube 2 is aligned with the inside of the rectangular groove 11, and the rectangular rod 13 is rotated to rotate the push rod 5 forty-five degrees. The push rod 5 drives the rotating disk 7 to rotate, so that the second through hole 9 rotates to a position corresponding to the first through hole 8. As the rectangular rod 13 is inserted, the push rod 5 is pushed into the first cooling tube 1, so that the spring 10 is stretched, so that the plug 6 is separated from the inner wall of the connecting tube 3, so that the first cooling tube 1 is conductive. Then, when the first cooling tube 1 and the second cooling tube 2 are in use, the coolant flows inside the first cooling tube 1 and the second cooling tube 2 with a larger flow rate.

[0025] A sealing disk 15 is fixedly connected to the inner surface of the plug 6, the rotating disk 7 fits in place with the inside of the sealing disk 15, a sealing ring is provided at the position where the sealing disk 15 contacts the rotating disk 7, and a sealing gasket is provided at the position where the rotating disk 7 contacts the plug 6. In this embodiment, the sealing of both sides of the rotating disk 7 is increased by providing a sealing ring inside the sealing disk 15, and the sealing between the rotating disk 7 and the plug 6 is increased by providing a sealing gasket between the rotating disk 7 and the plug 6, thereby reducing the possibility of coolant leakage.

[0026] The outer surface of the fixed disk 4 is fixedly connected to a spring 10, and the spring 10 is fixedly connected to the outer surface of the fixed disk 4 away from the fixed disk 4 and is fixedly connected to the plug 6. The spring 10 is sleeved on the outer surface of the push rod 5. In this embodiment, the push rod 5 is pushed into the first cooling tube 1, so that the spring 10 is stretched, so that the plug 6 is separated from the inner wall of the connecting tube 3, so that the first cooling tube 1 is guided. When the first cooling tube 1 and the second cooling tube 2 need to be disassembled, the rectangular rod 13 is rotated in the opposite direction and rotated forty-five degrees in the opposite direction, so that the rotating disk 7 blocks the first through hole 8, and then the second cooling tube 2 is pulled out. Under the elastic force of the spring 10, the plug 6 is driven to block the connecting tube 3 to prevent the coolant from flowing out.

[0027] Both ends of the connecting tube 3 are tapered. In this embodiment, one tapered end of the connecting tube 3 is fitted with the truncated cone-shaped plug 6, so that the plug 6 can seal the connecting tube 3 more stably and completely.

[0028] The plug 6 is in a truncated cone shape, and a sealing ring is fixedly connected to the outer surface of the plug 6. In this embodiment, the sealing ring is provided to increase the sealing between the plug 6 and the connecting tube 3, and the truncated cone shape of the plug 6 enables the plug 6 to seal the connecting tube 3 more completely.

[0032] Working principle: When the utility model is in use, the first cooling tube 1 and the second cooling tube 2 are spliced. When splicing, the rectangular rod 13 in the second cooling tube 2 is aligned with the inside of the rectangular groove 11, and the rectangular rod 13 is rotated to make the push rod 5 rotate forty-five degrees. The push rod 5 drives the rotating disk 7 to rotate, so that the second through hole 9 rotates to a position corresponding to the first through hole 8. As the rectangular rod 13 is inserted, the push rod 5 is pushed into the first cooling tube 1, so that the spring 10 is stretched, so that the plug 6 is separated from the inner wall of the connecting tube 3, so that the first cooling tube 1 is conductive. Then, when the first cooling tube 1 and the second cooling tube 2 are in use, the coolant flows inside the first cooling tube 1 and the second cooling tube 2 with a larger flow rate. When the first cooling tube 1 and the second cooling tube 2 need to be disassembled, the rectangular rod 13 is rotated in the opposite direction, so that it is rotated forty-five degrees in the opposite direction, so that the rotating disk 7 blocks the first through hole 8, and then the second cooling tube 2 is pulled out. Under the elastic force of the spring 10, the plug 6 is driven to block the connecting tube 3 to prevent the coolant from flowing out.
