Inside the opening 10, every four reinforcing connecting rods 4 form a group of connecting rods, one end of the connecting rod is fixedly connected to the connecting plate 8, and the other ends of the multiple reinforcing connecting rods 4 are fixedly connected to the limiting plate 9, one side outer wall of the limiting ring 2 5 is provided with a clamping ring 11, and one side outer wall of the clamping ring 11 is equidistantly provided with a plurality of clamping interfaces 12, and the outer walls of the multiple reinforcing connecting rods 4 are respectively in contact with the inner walls of the plurality of clamping interfaces 12, and the inner walls of the limiting ring 1 3 and the limiting ring 2 5 are fixedly connected with four inner support plates 6, and the outer walls of one side of the eight inner support plates 6 are respectively in contact with the outer walls of the two pipe bodies 1.
[0024] Specifically, when in use, the limit ring 1 3 and the limit ring 2 5 are respectively arranged on the two connected pipe bodies 1, so that the inner support plates 6 on the limit ring 1 3 and the limit ring 2 5 are respectively in contact with the two pipe bodies 1. At this time, the reinforcing connecting rod 4 is moved inside the movable opening 7 through the connecting plate 8, and passes through the through hole and the card interface 12. By rotating the clamping ring 11, the card interface 12 is rotated, so that the limit plate 9 and the clamping ring 11 cooperate to limit and fix the reinforcing connecting rod 4, thereby burying the pipe body 1.
[0025] Preferably, when in use, the device can provide limited support to the connecting end portion of the pipe through the limit ring 1 3, the inner support plate 6 and the limit ring 2 5 when the pipe is buried as a whole and is under pressure, so as to avoid changes in the curvature of the pipe connection and further avoid gaps at the connection, thereby ensuring that the pipe will not leak when in use and improving the use effect of the device.
[0026] In this embodiment, a portion of the reinforcing connecting rod 4 passes through the interior of the fixed base 2. When the device is subjected to stress, a portion of the pressure can be transmitted to the fixed base 2 through the reinforcing connecting rod 4 to increase the stress strength of the device.
[0027] In the present invention, two mounting rods 14 are fixedly connected inside the fixed base 2, the outer walls of the two mounting rods 14 are connected to the fixing plates 19 through bearings, and the outer walls of one side of the two fixing plates 19 are fixedly connected to the same elastic plate 13.

[0029] In the utility model, three elastic rods 18 are fixedly connected to the inner wall of one side of the two fixed plates 19, and the outer walls of the six elastic rods 18 are in contact with the outer wall of one side of the connecting plate 15. A connected locking opening 16 is opened on the outer wall of one side of the two fixed plates 19, and a fixing bolt 17 is provided inside the locking opening 16.
[0030] Specifically, when connecting the pipelines, the two pipeline bodies 1 to be connected are placed on the fixed base 2, and the positioning block 21 is inserted into the positioning port 20, so that the connecting plate 15 and the fixed base 2 are connected to the pipeline. At this time, the elastic plate 13 drives the fixed plate 19 to rotate toward the opposite side, and then drives the elastic rod 18 to contact the connecting plate 15, thereby pressurizing the connecting plate 15, so that the inner wall of the connecting plate 15 is tightly fitted with the outer wall of the pipeline body 1, and at the same time, the two fixed plates 19 are fixed by the fixing bolts 17 and the locking port 16, thereby completing the connection of the pipeline body 1.
[0031] Preferably, when in use, the elastic plate 13 can drive the two fixed plates 19 to automatically rotate and contact, so that the locking opening 16 is connected, which makes it convenient for the staff to quickly lock and fix the two fixed plates 19, thereby increasing the installation convenience when the device is in use. When fixing, the elastic rod 18 pressurizes the connecting plate 15, which can increase the fit between the connecting plate 15 and the pipe body 1 and improve the pipe connection effect.
[0032] In this embodiment, the positions of the fixed base 2 and the connecting plate 15 can be relatively fixed during use by means of the positioning opening 20 and the positioning block 21, thereby ensuring the accuracy of the fixed connection.
[0033] In the utility model, the inner wall of the fixed base 2 and the inner wall of one side of the connecting plate 15 are fixedly connected with an inner sealing seat 25, and the outer walls of the two inner sealing seats 25 are each provided with two elastic wave plates 22, and the outer walls of the four elastic wave plates 22 are respectively in contact with the inner walls of the two pipe bodies 1.
[0034] In the utility model, the inner wall of one of the inner sealing seats 25 is provided with two mounting openings 24, and the inner walls of one side of the two mounting openings 24 are fixedly connected with arc rods 26, and the outer walls of the two arc rods 26 are slidably connected with sealing members 23, and the inner walls of the two sealing members 23 are in contact with the inner walls of the two inner sealing seats 25.
[0035] In the utility model, the outside of the two arc rods 26 are both sleeved with pressure springs 27, one end of the two pressure springs 27 is respectively fixedly connected to the inner wall of one side of the two mounting openings 24, the other end of the two pressure springs 27 is respectively fixedly connected to the outer wall of one side of the two sealing members 23, and the outside of the two pressure springs 27 is both sleeved with protective sleeves 28.
[0036] Specifically, when the pipelines are connected, the inner sealing seat 25 is located at the interface of the two pipelines and inside thereof. At this time, the pressure spring 27 can drive the seal 23 to move on the arc rod 26, so that the seal 23 moves to the interface of the two inner sealing seats 25, thereby assisting in sealing the interface. At the same time, the elastic wave plate 22 can increase the sealing effect between the inner sealing seat 25 and the inner wall of the pipeline.
[0037] Preferably, when the pipeline is connected again, the connecting gap inside the pipeline can be blocked and sealed by the inner sealing seat 25 and the sealing member 23, so as to prevent the inside of the gap from being eroded by water flow and water seepage after long-term use, thereby improving the connection sealing effect of the device, and the gap on the inner sealing seat 25 can be blocked by the sealing member 23, thereby further increasing the sealing effect.
[0038] In this embodiment, the pressure spring 27 can be protected by the protective sleeve 28 to prevent the pressure spring 27 from rusting after long-term use, causing the seal 23 to move and affect the sealing effect.
