[0036] Based on the above technical solution, the connecting tube 201 has a connecting position and a replacement position along the rotation path of the rotating seat 2. When the connecting tube 201 is located at the connecting position, the first tube body 101, the connecting tube 201 and the second tube body 102 are connected. At this time, since a filter element 3 is provided in the connecting tube 201, the coolant can flow through the connecting tube 201 for filtration. When the connecting tube 201 is located at the replacement position, the connecting tube 201 is connected to the opening 1031. At this time, the first tube body 101 and the second tube body 102 are not connected, and the coolant is blocked in the first tube body 101, and the coolant will not leak. At this time, the used filter element 3 can be taken out from the opening 1031 for replacement, and the filter element 3 is more convenient to disassemble and assemble.

[0037] Preferably, the mounting base 1 includes a first mounting plate 103, a second mounting plate 104 and a fixed shaft 105. The first mounting plate 103 and the second mounting plate 104 are detachably arranged at both ends of the fixed shaft 105. The swivel base 2 is rotatably inserted on the fixed shaft 105.

[0039] More preferably, the rotating seat 2 includes a first rotating plate 202, a second rotating plate 203 and a rotating sleeve 204, the first rotating plate 202 and the second rotating plate 203 are fixedly arranged at both ends of the rotating sleeve 204, the rotating sleeve 204 is rotatably sleeved on the fixed shaft 105, the connecting tube 201 is fixedly arranged between the first rotating plate 202 and the second rotating plate 203, the connecting tube 201 is located on one side of the rotating sleeve 204, and the connecting tube 201 passes through the first rotating plate 202 and the second rotating plate 203.

[0040] Based on the above technical solution, the connecting pipe 201 passes through the first rotating plate 202 and the second rotating plate 203. When the connecting pipe 201 is not in the connected position, the first rotating plate 202 can block the coolant in the first tube body 101 to prevent the coolant from leaking when the filter element 3 is replaced.

[0041] More preferably, the first mounting plate 103 is provided with a first accommodating groove 1032 for partially accommodating the first rotating plate 202, and the second rotating plate 203 is provided with a second accommodating groove 2031 for partially accommodating the second mounting plate 104.

[0048] Specifically, the inlet pipe 10 and the outlet pipe 11 are made of soft hoses, the inlet pipe 10 is sleeved on the first tube body 101, and the outlet pipe 11 is sleeved on the second tube body 102. The first flange 1011 and the second flange 1021 respectively open the inner walls of the inlet pipe 10 and the outlet pipe 11 to increase the tension of the inlet pipe 10 and the outlet pipe 11, so as to increase the sealing between the inlet pipe 10 and the first tube body 101, and between the outlet pipe 11 and the second tube body 102.

[0049] More preferably, the pipe connection device further comprises a first throat hoop 7 and a second throat hoop 8, wherein the first throat hoop 7 is sleeved on the first pipe body 101 and is located on the side of the first flange 1011 close to the swivel seat 2, and the second throat hoop 8 is sleeved on the second pipe body 102 and is located on the side of the second flange 1021 close to the swivel seat 2. The first throat hoop 7 and the second throat hoop 8 are provided to fix the inlet pipe 10 on the first pipe body 101 and the outlet pipe 11 on the second pipe body 102, thereby preventing the inlet pipe 10 or the outlet pipe 11 from slipping off the first pipe body 101 or the second pipe body 102 when the coolant is circulated.

[0050] Preferably, the pipe connection device further includes a cover plate 9, which includes a cover body 901 and a rib 902 disposed on the cover body 901, and the cover body 901 is disposed at the opening 1031.

When one of the connecting tubes 201 is located at the connecting position, the other connecting tube 201 is located at the replacement position. Filter elements 3 are arranged inside the two connecting tubes 201. When there is a need to replace the filter element 3, the connecting tube 201 in the connecting position is rotated to the replacement position, and the connecting tube 201 in the replacement position is rotated to the connecting position along with the connecting tube 201 in the connecting position, and the filter element 3 is quickly replaced. At this time, the cover plate 9 is opened, the used filter element 3 is taken out, and a new filter element 3 is replaced. The cover plate 9 is closed to complete the replacement operation.

[0052] Specifically, the rotation angle required to turn from the connecting position to the changing position is 180°.

[0053] In summary, the embodiment of the utility model provides a pipeline connection device, wherein the connecting pipe 201 has a connecting position and a replacement position along the rotation path of the rotating seat 2.
