DETAILED DESCRIPTION
[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0024] A typical implementation of the present utility model is as follows Figure 1 As shown, a double-groove clamp pipe connection structure includes a wire mesh skeleton polyethylene pipe 1, a double-groove iron sheet joint 2 is sleeved on the outer side of the wire mesh skeleton polyethylene pipe 1, an inner core iron sheet joint 3 is arranged on the inner side of the wire mesh skeleton polyethylene pipe 1, a double-groove clamp outer clamp 4 is fastened with bolts on the outer side of the double-groove iron sheet joint 2, and a sealing ring 5 is arranged at the front end of the double-groove iron sheet joint 2 to play a sealing role.
[0025] like Figure 2 As shown, the double groove iron sheet joint 2 is a tubular structure, and its inner diameter is the same as the outer diameter of the steel wire skeleton polyethylene pipe 1. A plurality of rows of inner inverted teeth 23 are arranged on the inner wall of the double groove iron sheet joint 2. The plurality of rows of inner inverted teeth 23 are arranged parallel to the inner surface of the double groove iron sheet joint 2. The inner inverted teeth 23 are tightly bitten on the outer surface of the steel wire skeleton polyethylene pipe 1 through a buckle compression neck. In addition, a first groove 21 and a second groove 22 are opened at one end of the outer surface of the double groove iron sheet joint 2.
[0026] like Figure 4 As shown, the inner wall of the double-groove clamp outer card 4 is provided with a first boss 41 and a second boss 42, and the first boss 41 and the second boss 42 are respectively adapted to the first groove 21 and the second groove 22, and the first boss 41 and the second boss 42 on the double-groove clamp outer card 4 can be respectively inserted into the first groove 21 and the second groove 22 of the double-groove iron joint 2, thereby playing a pressure-bearing role.
[0027] like Figure 3 As shown, the inner core iron sheet joint 3 is a tubular structure, and its outer diameter is the same as the inner diameter of the steel wire skeleton polyethylene pipe 1. The outer surface of the inner core iron sheet joint 3 is provided with multiple rows of external beveled teeth 31, and the multiple rows of external beveled teeth 31 are arranged parallel to the outer surface of the inner core iron sheet joint 3. When the inner core iron sheet joint 3 is placed inside the steel wire mesh skeleton polyethylene pipe 1, the external beveled teeth 31 bite tightly on the inner surface of the steel wire mesh skeleton polyethylene pipe 1, thereby increasing the overall pressure resistance of the joint device.
[0028] The sealing ring 5 is arranged at the front end of the double-groove iron sheet joint 2 and is made of EPDM. It plays a sealing role by closely cooperating with the double-groove clamp outer clamp 4 through the pressure flowing inside the pipe body.
