A cylindrical wide-band sealing ring is put on the pipe and inserted into the socket of the ring-pressed pipe fitting. A special tool is used to apply pressure from the outside along the circumference of the socket, so that the socket and the pipe are concave and deformed together and the sealing section of the socket is compressed, thereby achieving a connection method in which the pipe and the fittings are tightened and sealed.

By setting the second spring damper 43 to cooperate with the upper clamping piece 3, the upper clamping plate 44 is flexibly fitted to the upper surface of the pipeline connection. The end of the second spring damper 43 away from the upper clamping piece 3 is fixedly connected to the upper clamping plate 44, and a pull plate 45 is slidably connected to the inner wall of one side of the upper clamping piece 3. The pull plate 45 is provided to facilitate personnel to operate and pull. An arc column 46 is fixedly connected to the outer wall of one side of the pull plate 45. By setting the arc surface on the arc column 46, when the upper clamping piece 3 is pressed close to the lower clamping piece 1, different fixing holes 40 are sequentially clamped. At the same time, when the upper clamping piece 3 and the lower clamping piece 1 are opened and moved away, the arc column 46 is clamped with the fixing hole 40, and a telescopic spring 47 is fixedly connected to the outer wall of the side of the pull plate 45 away from the arc column 46.

[0025] Reference Figure 2-Figure 4 There are five fixing holes 40 in total, and the five fixing holes 40 are respectively opened in sequence on one side outer wall of the lower clamp 1. By setting the fixing holes 40, it is convenient for the arc column 46 to clamp different fixing holes 40 so as to perform ring pressure fixing according to different sizes of pipes. The upper clamp 3 is movably sleeved on the connecting rod 41, the lower clamp plate 42 is slidably connected to the inner wall of one side of the lower clamp 1, and the upper clamp plate 44 is slidably connected to the inner wall of one side of the upper clamp 3.

[0026] Reference Figure 3-Figure 4The auxiliary mechanism 5 includes a threaded groove 51, which is provided on the connecting rod 41. The threaded groove 51 is provided to facilitate the installation and disassembly of the connecting rod 41, so that the damaged parts of the upper clamp 3 and the lower clamp 1 can be replaced separately, reducing the overall replacement of the ring-pressed pipe fittings after damage, thereby increasing the cost problem. The end of the connecting rod 41 away from the threaded groove 51 is fixedly connected with a turntable 52, and the turntable 52 is provided to facilitate personnel to rotate and disassemble the connecting rod 41. An annular groove 53 is provided on the outer wall of one side of the lower clamp 1, and the threaded groove 51 is threadedly connected to the inner wall of one side of the lower clamp 1. A strip groove is provided on the side outer wall of the turntable 52.

The annular groove 53 is provided to prevent the turntable 52 from protruding to the outside and being easily damaged and loosened by external collision.

[0027] Working principle: According to the different outer diameters of the pipes, the lower clamp 1 and the upper clamp 3 are sleeved at the pipe connection, and then the upper clamp 3 is pressed close to the lower clamp 1, so that the arc column 46 is annularly clamped in the corresponding fixing hole 40. When the upper clamp 3 and the lower clamp 1 are pressed into place, the reverse surface of the arc column 46 is clamped with the fixing hole 40 to prevent the upper clamp 3 and the lower clamp 1 from opening and loosening. At the same time, when the upper clamp 3 moves, it drives the upper clamp plate 44 to fit the upper surface of the pipe to squeeze the second spring damper 43 for a certain degree of flexible clamping. At the same time, the lower clamp plate 46 on the lower clamp 1 is clamped with the second spring damper 43. 2 cooperates with the upper clamping plate 44 to fit the lower surface of the pipe connection, squeezes the first spring damper 411 to perform a certain degree of flexible clamping on the lower surface to prevent hard clamping, which may cause the clamping mouth to loosen when the pipe expands or contracts or shakes and deforms. At the same time, under long-term use or disassembly and replacement, some parts of the ring-pressed pipe fittings will be damaged. When the turntable 52 is rotated, the connecting rod 41 rotates, and the rotation of the connecting rod 41 drives the thread groove 51 to rotate. The thread groove 51 rotates and separates from the lower clamp 1. Then the upper clamp 3 is pulled out, and the damaged upper clamp 3 or lower clamp 1 is replaced separately.
