[0018] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0019] See also Figures 1 to 4A wire mesh skeleton pipe sealing ring, comprising: a sealing ring body 3 and a welding part 4; the sealing ring body 3 is made of plastic, and one side of the sealing ring body 3 is provided with a fitting surface 31 that can be fitted on the end surface of the wire mesh skeleton pipe 200, and a first annular mounting groove 32 is provided along the fitting surface 31; the welding part 4 is annular and embedded in the first annular mounting groove 32, and one side of the welding part 4 close to the notch of the first annular mounting groove 32 is flush with the fitting surface 31 or protrudes from the fitting surface 31 so as to contact the steel wire 201 on the end surface of the wire mesh skeleton pipe; the welding part 4 can be heated to melt by an electromagnetic induction welding gun; on the fitting surface 31, overflow grooves 33 that can collect the melted welding part 4 are provided along the outer periphery and inner periphery of the first annular mounting groove 32.

[0020] Through the above arrangement, the welding portion 4 can be heated by an electromagnetic induction welding gun and welded to the steel wire on the end surface of the wire mesh skeleton pipe to complete the sealing, saving time and effort.

[0021] When the present application is used, the sealing ring is held in hand with the fitting surface 31 facing the end of the wire mesh skeleton pipe, and the welding part 4 is placed against the steel wire at the end of the wire mesh skeleton pipe. At this time, the sealing ring body 3 is coaxially arranged with the wire mesh skeleton pipe, and the welding part 4 is heated by holding an electromagnetic induction welding gun purchased from the market. The heating principle can refer to the induction cooker. The welding part 4 is quickly heated and melted into liquid metal. When the liquid metal overflows the first annular mounting groove 32, the overflow groove 33 can collect the liquid metal overflowing the first annular mounting groove 32. After the liquid metal contacts the steel wire, it is naturally cooled and solidified. At this time, the sealing ring body 3 is welded to the steel wire through the welding part 4. See Figure 4 The sealing ring body 3 covers the steel wire to complete the sealing, and the whole process saves time and effort.

[0022] As an implementation method, the sealing ring also includes: an outer anti-slipping copper wire 5 and an inner anti-slipping copper wire 6; the outer anti-slipping copper wire 5 is buried in the sealing ring body 3, and an outer card groove 41 is provided on the outer periphery of the welding part 4, and the outer anti-slipping copper wire 5 extends along the radial direction of the sealing ring body 3 and is inserted into the outer card groove 41; the inner anti-slipping copper wire 6 is buried in the sealing ring body 3, and an inner card groove 42 is provided on the inner periphery of the welding part 4, and the inner anti-slipping copper wire 6 extends along the radial direction of the sealing ring body 3 and is inserted into the inner card groove 42.

[0023] Through the above arrangement, the welding portion 4 is not easily separated from the first annular mounting groove 32 .

[0024] Initially, the outer anti-slipping copper wire 5 and the inner anti-slipping copper wire 6 can prevent the welding part 4 from leaving the first annular mounting groove 32; when welding with an electromagnetic induction welding gun, the outer anti-slipping copper wire 5 and the inner anti-slipping copper wire 6 are made of copper, which does not have ferromagnetism. Therefore, copper will not heat up and melt when the electromagnetic induction welding gun heats the welding part 4. The outer anti-slipping copper wire 5 and the inner anti-slipping copper wire 6 are stably pre-buried in the sealing ring body 3. After the welding part 4 and the steel wire are welded together, the outer anti-slipping copper wire 5 and the inner anti-slipping copper wire 6 continue to connect the welding part 4 to prevent the welding part 4 from leaving the first annular mounting groove 32, thereby preventing the sealing ring body 3 from falling off from the end of the wire mesh skeleton pipe.

[0025] As an implementation method, the sealing ring also includes: an outer hot melt adhesive 7 and an inner hot melt adhesive 8; a second annular mounting groove 34 is arranged on the fitting surface 31, and the second annular mounting groove 34 is concentrically arranged on the outer side of the first annular mounting groove 32. The outer hot melt adhesive 7 is annular and arranged in the second annular mounting groove 34, and the outer hot melt adhesive 7 is in contact with the outer anti-stripping copper wire 5; a third annular mounting groove 35 is arranged on the fitting surface 31, and the third annular mounting groove 35 is concentrically arranged on the inner side of the first annular mounting groove 32. The inner hot melt adhesive 8 is annular and arranged in the third annular mounting groove 35, and the inner hot melt adhesive 8 is in contact with the inner anti-stripping copper wire 6.

[0026] Through the above arrangement, when the electromagnetic induction welding gun is welding, the outer hot melt adhesive 7 and the inner hot melt adhesive 8 melt and bond the sealing ring body 3 to the wire mesh skeleton pipe, further improving the stability of the sealing ring body 3 on the end of the wire mesh skeleton pipe; in addition, the outer hot melt adhesive 7 and the inner hot melt adhesive 8 can also prevent moisture from entering and corroding the steel wire.

[0027] In the present application, the outer anti-stripping copper wire 5 and the inner anti-stripping copper wire 6 have good thermal conductivity. When welding with an electromagnetic induction welding gun, after the welding part 4 is heated, the heat of the welding part 4 passes through the outer anti-stripping copper wire 5 to heat the outer hot melt adhesive 7. The outer hot melt adhesive 7 melts and bonds the sealing ring body 3 to the wire mesh skeleton pipe. Similarly, the inner hot melt adhesive 8 melts and bonds the sealing ring body 3 to the wire mesh skeleton pipe.

[0028] As an implementation method, one end of the outer anti-slipping copper wire 5 away from the welding part 4 extends to the bottom of the second annular mounting groove 34 and is vertically fixedly connected with a first connecting column 9, and the first connecting column 9 is inserted into the outer hot melt adhesive 7; one end of the inner anti-slipping copper wire 6 away from the welding part 4 extends to the bottom of the third annular mounting groove 35 and is vertically fixedly connected with a second connecting column 10, and the second connecting column 10 is inserted into the inner hot melt adhesive 8.

[0029] Through the above arrangement, the outer hot melt adhesive 7 can be prevented from escaping from the second annular mounting groove 34 , and the inner hot melt adhesive 8 can be prevented from escaping from the third annular mounting groove 35 .

[0030] As an implementation method, one side of the welding portion 4 close to the notch of the first annular mounting groove 32 protrudes from the fitting surface 31 by one millimeter.

[0031] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
