Due to the difficulty in disassembly, replacing the pipeline or repairing it requires more time and effort, especially in an emergency, which will prolong the repair time. Therefore, a sealing pipe fitting for automobile pipelines is proposed to solve the above problems. Utility Model Content

Due to the difficulty in disassembly, replacing the pipeline or repairing it requires more time and effort, especially in an emergency, which prolongs the repair time.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sealing connecting pipe fitting for automobile pipelines, comprising pipeline 1, the outer periphery of pipeline 1 is movably connected with pipeline 2, the top outer periphery of pipeline 2 is fixedly connected with a connecting block, the left and right sides of the connecting block are slidably connected with pull rods, the two pull rods are fixedly connected with arc plates on the opposite sides, the outer peripheries of the two pull rods are fixedly connected with spring 1, the far sides of the two springs are fixedly connected with limit plates 1, the two arc plates are fixedly connected with sealing rings on the opposite sides, and limit components are provided on the left and right sides of the interior of pipeline 2.
[0006] Furthermore, the limit assembly includes a limit column, which is slidably connected to the inside of the second pipeline, and the middle of the limit column is fixedly connected to the second limit plate, and one side of the second limit plate is fixedly connected to the second spring, and the second spring is sleeved on the outer periphery of the limit column.
[0007] Furthermore, an inner ring is slidably connected to the bottom of the outer circumference of the pipeline 2, an outer shell is fixedly connected to the outer circumference of the inner ring, a fixed ring is fixedly connected to the middle of the outer circumference of the pipeline 2, and a compression spring is fixedly connected between the fixed ring and the inner ring.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a sealing pipe connection fitting for automobile pipelines, comprising a pipeline 1, the outer periphery of the pipeline 1 is movably connected with a pipeline 2, the outer periphery of the top of the pipeline 2 is fixedly connected with a connecting block 3, the left and right sides of the connecting block 3 are slidably connected with pull rods 5, the two pull rods 5 are fixedly connected with arc plates 8 on the opposite sides, the outer peripheries of the two pull rods 5 are fixedly connected with springs 17, the far sides of the two springs 17 are fixedly connected with limit plates 16, the two arc plates 8 are fixedly connected with sealing rings 9 on the opposite sides, the left and right sides of the interior of the pipeline 2 are provided with limit assemblies, the far sides of the two pull rods 5 are fixedly connected with pull plates 4, and the insides of the two arc plates 8 are in contact with the outer periphery of the pipeline 1.
[0023] Specifically, pipeline 2 is used to fix each pipeline 1, the connecting block 3 is used to accommodate the internal seal to provide a sealing effect for the pipeline, the pull plate 4 is used to facilitate the control of the movement of the pull rod 5, the pull rod 5 is used to connect the arc plate 8, the limit plate 6 is fixedly connected to the middle of the pull rod 5, and when the pull rod 5 moves, the limit plate 6 can move with the pull rod 5, the spring 7 is used to provide elastic support, the arc plate 8 is used to connect the sealing ring 9, and the sealing ring 9 is used to provide a sealing effect when the pipeline 1 is connected to other pipelines.
[0024] Reference Figure 1 and Figure 3 The limiting assembly includes a limiting column 15, which is slidably connected to the inside of the pipeline 2, and a limiting plate 16 is fixedly connected to the middle of the limiting column 15. A spring 17 is fixedly connected to one side of the limiting plate 16. The spring 17 is sleeved on the outer periphery of the limiting column 15, and an inner ring 11 is slidably connected to the bottom of the outer periphery of the pipeline 2. The outer periphery of the inner ring 11 is fixedly connected to the outer shell 10. A fixing ring 13 is fixedly connected to the middle of the outer periphery of the pipeline 2, and a compression spring 14 is fixedly connected between the fixing ring 13 and the inner ring 11. Slide grooves 12 are provided on both sides of the inside of the pipeline 2, and the limiting plate 16 is slidably connected to the inside of the slide groove 12. An arc groove 18 is provided inside the inner ring 11. One end of the limiting column 15 is slidably connected to the inside of the arc groove 18, and the end of the limiting column 15 away from the arc groove 18 is embedded in the outer periphery of the pipeline 1.
[0025] Specifically, the outer shell 10 is used to protect multiple internal parts. A compression spring 14 is connected between the inner ring 11 and the fixed ring 13. When the inner ring 11 moves, the compression spring 14 can be squeezed. The limit column 15 is used to limit the pipeline 1 so that the pipeline 1 is inside the pipeline 2. The slide groove 12 is used to provide a space for the limit plate 2 16 to slide. The spring 2 17 is used to provide elastic reset movement. The arc groove 18 is used to accommodate one end of the limit column 15. The limit plate 2 16 is inside the slide groove 12 to limit the movement range of the limit column 15.
[0026] Working principle: When installing the pipeline 1 inside the pipeline 2, first slide the outer shell 10 upward. When the outer shell 10 slides, the inner ring 11 moves with the outer shell 10 accordingly to squeeze the compression spring 14. At this time, the limit column 15 inside the pipeline 2 will slide into the arc groove 18 along the inner wall of the arc groove 18, so that one end of the limit column 15 loses the pressure, and the spring 2 17 can be reset to push the limit plate 2 16 to move. When the limit plate 2 16 moves, the limit column 15 moves, and the limit column 15 One end slides into the arc groove 18, and then the pipeline 11 is inserted into the pipeline 2 2. After selecting the appropriate position, the outer shell 10 can be loosened, and the compression spring 14 can be reset when it loses the squeezing force of the inner ring 11 to generate thrust to push the inner ring 11 to move downward. Therefore, when the inner ring 11 moves, the limit column 15 will slide along the inner wall of the arc groove 18, so that the inner ring 11 will form a squeezing force on the limit column 15, so that one end of the limit column 15 abuts against the outer periphery of the pipeline 1, so that the pipeline 1 is fixed inside the pipeline 2 2.
[0027] Secondly, when installing the pipeline 1, by pulling the pull plates 4 on both sides of the connecting block 3, the two pull plates 4 move together with the two pull rods 5, the limit plates 6 on the outer periphery of the pull rods 5 will squeeze the springs 7, and the arc plate 8 will move with the pull rods 5. Then, after the pipeline 1 enters the connecting block 3, the two pull plates 4 can be released, and the spring 7 can be reset without the pressure of the limit plates 6 to generate thrust to push the limit plates 6 to move, so that the limit plates 6 drive the arc plate 8 to move, and the two sealing rings 9 can be tightly contacted with the outer periphery of the pipeline 1, thereby providing a sealing effect.
