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.

The connecting component includes a sleeve plate 21, the sleeve plate 21 is elastically connected with a positioning plate 23 through a compression spring 22, the positioning plate 23 slides laterally along the outer wall of the pipeline 1, and a slider 24 is fixedly connected to the upper surface of the positioning plate 23, and a through groove 202 is opened at the right end of the inner wall of the positioning plate 23, and a sealing component is provided on the upper surface of the slider 24, and the sealing component can ensure the sealing inside the sleeve plate 21, prevent external rainwater and impurities from penetrating into the sleeve plate 21, and ensure the stability of the use of the connecting component.

[0032] Reference Figure 1 , Figure 3 , Figure 4 The connecting component also includes a rubber ring 25. A card slot 201 is provided on the front surface of the pipe 1. The card slot 201 is provided in an arc shape. A card block 26 is passed through and slidably connected to the upper surface of the pipe 1. The size of the card block 26 and the card slot 201 are matched.

[0033] Reference Figure 1 - Figure 3 The sealing assembly includes a rubber ring 31, a fixing plate 32 is fixedly connected to the upper surface of the slider 24, a rubber plate 33 is penetrated and slidably connected to the lower surface of the fixing plate 32, the lower surface of the rubber plate 33 is made of rubber, a magnet block 2 35 is fixedly connected to the upper surface of the rubber plate 33, and a magnet block 1 34 is fixedly connected to the inner wall of the top of the fixing plate 32. The magnet block 2 35 and the magnet block 1 34 repel each other, and the force generated by the repulsion will cause the rubber plate 33 to squeeze the rubber ring 31 downward to maintain sealing.

[0034] Reference Figure 1 - Figure 3 The inner wall of the rubber ring 31 is fixedly connected to the outer wall of the sleeve plate 21 , the slider 24 penetrates and is slidably connected to the upper surface of the rubber ring 31 , sliding laterally, and the rubber plate 33 is piston-connected to the outer wall of the slider 24 .

[0035] Reference Figure 1 , Figure 3 , Figure 4The sleeve plate 21 is fixedly connected to the outer wall of the pipe 1, the positioning plate 23 is slidably connected to the outer wall of the pipe 1, one end of the compression spring 22 is fixedly connected to the left surface of the positioning plate 23, and the other end of the compression spring 22 is fixedly connected to the inner wall on the left side of the sleeve plate 21. When the positioning plate 23 moves to the left, it will squeeze the compression spring 22 to generate a reaction force, and when the positioning plate 23 moves, it will drive the through slot 202 to move.

[0036] Reference Figure 1 , Figure 3 , Figure 4 The positioning plate 23 is slidably connected to the inner wall of the sleeve plate 21 , the slider 24 penetrates and is slidably connected to the upper surface of the sleeve plate 21 , and the outer wall of the slider 24 fits the sleeve plate 21 .

[0037] Reference Figure 1 , Figure 3 , Figure 4 The outer wall of the rubber ring 25 is fixedly connected to the right end of the inner wall of the pipe 1, multiple groups of blocks 26 are provided, and multiple groups of slots 201 are opened. The multiple groups of blocks 26 and slots 201 are arranged in a circular array with the center of the pipe 1 as the origin.

[0038] Reference Figure 1 , Figure 3 , Figure 4 The block 26 is inserted into the inner wall of the slot 201 and can limit the position of the pipe 1. The upper surface of the block 26 is set as an arc surface, and the lower surface of the block 26 is set as an arc surface. When the arc surface of the upper surface of the block 26 is squeezed, the block 26 will move toward the center of the pipe 1. When the arc surface of the lower surface of the block 26 is squeezed, the block 26 will move away from the center of the pipe 1.

[0039] Working principle: When the device is used, first slide the fixing plate 32 to the left, and the fixing plate 32 moving to the left will drive the magnet block 1 34, the magnet block 2 35, the rubber plate 33 and the slider 24 to move to the left, and the slider 24 moving to the left will drive the positioning plate 23 to move to the left, and the positioning plate 23 moving to the left will squeeze the compression spring 22 to generate a reaction force. When the through groove 202 and the block 26 are aligned, the left end of another pipe 1 is plugged into the right end of this pipe 1. During the plugging process, the left surface of the other pipe 1 will squeeze the arc surface of the lower surface of the block 26, and multiple groups of blocks 26 will Open outward to remove the obstruction. When the two groups of pipes 1 are connected, the left surface of the other pipe 1 will be tightly attached to the right surface of the rubber ring 25 to ensure sealing, and the slot 201 will be aligned with the block 26. At this time, release the fixing plate 32, and the reaction force of the compression spring 22 will push the fixing plate 32, magnet block 1 34, magnet block 2 35, rubber plate 33, slider 24 and positioning plate 23 to move right. The positioning plate 23 moving to the right will squeeze the arc surface on the upper surface of the block 26. Multiple groups of blocks 26 will shrink synchronously and connect with the slot 201 to connect the two groups of pipes 1 together.

[0040] When the two groups of pipes 1 need to be separated, the fixing plate 32 is moved to the left to drive the positioning plate 23 to move to the left to squeeze the compression spring 22 to generate a reaction force. The positioning plate 23 moving to the left will also drive the through slot 202 to move. When the through slot 202 and the block 26 are aligned, the positioning plate 23 will release the squeezing of the block 26, and then the two groups of pipes 1 will be separated. During the separation process, the slot 201 will squeeze the arc surface of the lower surface of the block 26, and the block 26 will simultaneously open outward to release the obstruction. After the two groups of pipes 1 are separated, the fixing plate 32 is released, and the reaction force of the compression spring 22 will push the device to reset.

[0041] During use of the device, the repulsive force generated between the first magnet block 34 and the second magnet block 35 will push the rubber plate 33 downward to always be in close contact with the rubber ring 31 to ensure the sealing of the device.
