[0021] like Figure 1-5 As shown, an electrical conduit sealing peripheral comprises a conduit 1, wherein the outer surface of the connection of the two conduits 1 is wrapped with a plurality of circles of sealing tape 2, the outer surface of the sealing tape 2 located at the end of the connection of the two conduits 1 is wrapped with a thin iron sheet 3, the two ends of the thin iron sheet 3 are wrapped with the sealing tape 2 for one circle and are close to each other and fixedly connected with a small leaf spring 4, the ends of the small leaf spring 4 extending outward are fixedly connected with a connecting block 5, the insides of the two connecting blocks 5 are penetrated and fixedly connected with a screw nut 6, the outer surfaces of the conduit 1 and the sealing tape 2 are located on both sides of the thin iron sheet 3 and are sleeved with a fixing ring 7, the adjacent parts of the two fixing rings 7 on the same side are fixedly connected with an extension block 9, and the two extension blocks 9 contacting each other are penetrated and fixedly connected with a screw nut 1 0, by first wrapping the two pipes 1 with the sealing tape 2, and then wrapping the thin iron sheet 3 around the surface of the two ends of the pipes 1 and wrapped with the tape, then passing the screw nut 6 through the two connecting blocks 5 and tightening until the small leaf spring 4 is slightly bent, and then fixing the fixing ring 7 on the outer surface of the pipe 1, using its thickness to protect the remaining exposed sealing tape 2 and small leaf spring 4 and other structures, and then when the pipe 1 expands due to temperature and other reasons, it drives the thin iron sheet 3 to expand outward, at this time, the two small leaf springs 4 will be pulled and will bend more to adapt to the expansion, on the contrary, the force of pre-tightening to make the small leaf spring 4 slightly bent during contraction will pull the thin iron sheet 3 toward the end, so that the pipe 1 can be tightly clamped at the connection of the pipe 1 when it contracts.

[0022] like Figure 4 As shown, in some embodiments, the inner surface of the fixing ring 7 is arrayed and fixedly connected with a plurality of rubber rings 8, the inner surface of the fixing ring 7 extending out of the sealing tape 2 is fixedly connected with a rubber ring 8, the rubber ring 8 contacts the outer surface of the pipe 1, and the remaining rubber rings 8 are fixedly connected to the inner surface of the pipe 1 around the sealing tape 2 and contact the outer surface of the sealing tape 2. Specifically, the sealing tape 2 is clamped on both sides of the thin iron sheet 3 by the installed rubber rings 8, and at the same time, the rubber rings 8 have a certain deformation ability so that the pipe 1 can be tightly attached to the tape and the surface of the pipe 1 when it expands and contracts due to heat, thereby providing an auxiliary sealing effect.

[0023] like Figure 2As shown, in some embodiments, grooves 11 are provided at both ends of the thin iron sheet 3, and the two grooves 11 are respectively opened from the middle to the left and right sides, and the small leaf spring 4 is fixedly connected to the surface of the thin iron sheet 3 on the other side where the groove 11 is provided, and the connecting block 5 is fixedly connected to the side where the end of the small leaf spring 4 extends near the middle of the sealing tape 2.
