[0033] like Figure 1-5 As shown, this embodiment proposes an anti-seepage connection device for electrical tightening pipes, including a junction box 1 and a working pipe 2, the junction box 1 is installed with the working pipe 2, the working pipe 2 is provided with a heat shrink joint 3, the working pipe 2 is provided with a vacuum intervention hole 4, the working pipe 2 is fixedly connected with a claw-shaped clip 5, the claw-shaped clip 5 is fixedly connected with a sealing gasket 6, the working pipe 2 is provided with a tightening conduit 7, the tightening conduit 7 is provided with a threaded groove 9, the threaded groove 9 is threadedly connected with a locking screw 8, the tightening conduit 7 is provided with a positioning groove 10, and the heat shrink joint 3 is provided with a thermal wire mesh 11.

[0034] Example 2:

[0035] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0036] like Figure 2As shown, as a preferred embodiment, on the basis of the above method, further, a connecting frame 12 is fixedly connected to the working tube 2, and a threaded sleeve 13 is rotatably connected to the connecting frame 12. The material of the heat shrink joint 3 is easy to shrink and the viscosity increases when heated, which can ensure that the damage of the heat shrink joint 3 can improve the sealing effect.

[0037] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, a turntable 14 is fixedly connected to the threaded sleeve 13, a threaded rod 15 is threadedly connected to the threaded sleeve 13, and the connecting frame 12 is symmetrically distributed on the left and right sides of the working pipe 2. The connecting frame 12 corresponds to the turntable 14 one by one through the threaded sleeve 13, which can ensure that the installation effect can be improved under the cooperation of the threaded sleeves 13 on both sides.

[0038] like Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, a support plate 16 is fixedly connected to the threaded rod 15, and a support plate 17 is rotatably connected to the threaded rod 15. The threaded rod 15 is fixedly connected to the center part of one side of the support plate 16, which can ensure that the threaded rod 15 can move smoothly under the support of the support plate 16 when rotating.

[0039] like Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, a guide rod 18 is fixedly connected to the support plate 17, and the guide rod 18 is slidingly connected to the connecting frame 12 with a limited position, and the side end face of the support plate 16 is in contact with the inner side face of the threaded sleeve 13, which can ensure that the support plate 16 can move smoothly through the support of the inner side face of the threaded sleeve 13 when moving.

[0040] like Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, the threaded rod 15 is rotatably connected to the center part of one side of the support plate 17, and the guide rods 18 are symmetrically distributed on the left and right sides of the support plate 17, which can ensure that the support plate 17 can use the support of the guide rods 18 on both sides to correspond smoothly when moving.

[0041] Specifically, when using the electrical set pipe anti-seepage connection device: Figure 1-5 When using the equipment, the two working tubes 2 can be inserted into the positioning groove 10 of the tightening tube 7. The positioning groove 10 is located in the middle of the tightening tube 7 to ensure that the lengths of the working tubes 2 on both sides are equal. When the working tube 2 reaches the tightening position, it is tightly attached to the two ends of the positioning groove 10. At this time, not only the positioning function is completed, but also the first sealing function is achieved. Next, the locking screw 8 is tightened by a torque wrench and screwed into the thread groove 9 of the tightening tube 7, which fixes the working tube 2. Further, the locking screw 8 continues to be screwed in and tightened until the torque of the locking screw 8 meets the standard requirements.

[0042] The vacuum intervention hole 4 is connected to the external vacuum equipment to extract the air between the heat shrink joint 3 and the tightening conduit 7 and the working tube 2. Further, the heat shrink joint 3 is tightly attached to the tightening conduit 7 and the working tube 2 to achieve a second sealing effect. There are two vacuum intervention holes 4 on the heat shrink joint 3, namely the upper vacuum intervention hole 4 and the horizontal side vacuum intervention hole 4, and the two vacuum intervention holes 4 are located at both ends of the heat shrink joint 3 and are distributed at 90°. The effect of this design is that the direction of the vacuum intervention hole 4 is vertically upward and horizontally, and is at both ends of the heat shrink joint 3. This arrangement facilitates the placement of equipment on the construction site and the connection with external equipment during operation.

[0043] The heat conductive wire mesh 11 is heated by an external heating device, and the heat is quickly transferred to the heat shrink joint 3 closely located thereunder. The heat shrink joint 3 shrinks due to the heat and is tightly attached to the fixing conduit 7 and the working tube 2, thereby achieving a third sealing effect to prevent leakage. In this way, the anti-leakage effect of the device is achieved, and it is convenient to protect the junction box 1 connected to the fixing conduit 7 and the working tube 2, thereby avoiding damage to the circuits and the like in the junction box 1.

[0044] In order to improve the firmness and sealing of the connection between the fixing conduit 7 and the working pipe 2 and the junction box 1, the claw-shaped clip 5 on the working pipe 2 is installed in the junction box 1, and the turntables 14 on both sides can be rotated to drive the threaded sleeve 13 to rotate on the connecting frame 12. When the threaded sleeve 13 rotates, it can push the threaded rod 15 to move. When the threaded rod 15 moves, it can move smoothly with the support of the supporting plate 16. When the threaded rod 15 moves, it can push the support plate 17 to move. When the support plate 17 moves, it can move smoothly with the support of the guide rods 18 on both sides. When the support plate 17 continues to move while being attached to the junction box 1, it can push the working pipe 2 to move. When the working pipe 2 moves, it can drive the claw-shaped clip 5 to fit smoothly on the inner side of the junction box 1, and the sealing gasket 6 on the claw-shaped clip 5 is tightly fitted in the junction box 1, so that the pipeline is firmly installed, and the sealing effect can be improved to avoid leakage.

[0045] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements that do not deviate from the spirit and scope of the utility model are included in the scope of the claims of the present invention.
