The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] The first embodiment of the present application is:

[0021] See also Figure 1-Figure 4 ,in Figure 1 This is a front view of the first embodiment of the utility model. Figure 2 The utility model Figure 1 AA line section view, Figure 3 The utility model Figure 2 BB line cross-sectional view, Figure 4 The utility model Figure 3 Enlarged view of the local structure at location C.

[0022] The utility model provides a steel pipe connecting groove pipe fitting, including two clamping plates 101, multiple limiting members 102, two buffer members 103 and multiple locking members 104, each of the buffer members 103 includes an isolation ring 105, two buffer spring plates 106 and two supporting plates 107, each of the clamping plates 101 includes a plate body 108, two side ears 109 and two side plates 110, each of the limiting members 102 includes a thrust spring 111, a movable block 112 and a limiting column 113, and each of the locking members 104 includes a locking nut 114 and a locking cap 115.

[0023] According to the present specific embodiment, each of the locking members 104 is respectively fixedly connected to the corresponding card plate 101, each of the limiting members 102 is respectively fixedly connected to the corresponding card plate 101, each of the abutting plates 107 is respectively fixedly connected to the corresponding buffer spring plates 106, the other side of each buffer spring plate 106 is fixedly connected to the isolation ring 105, the isolation ring 105 is fixedly connected to the corresponding card plate 101, the two side plates 110 are respectively fixedly connected to the plate body 108, the two side ears 109 are respectively fixedly connected to the plate body 108, the upper end of the limiting column 113 is respectively fixedly connected to the movable block 11 2 is fixedly connected, the upper part of the movable block 112 is fixedly connected to the thrust spring 111, the upper end of the thrust spring 111 is fixedly connected to the side plate 110, the locking cap 115 is rotatably connected to the locking nut 114, and the locking nut 114 is fixedly connected to the corresponding side ear 109. The supporting plate 107 currently provided cooperates with the buffer spring plate 106 to provide buffer support after the steel pipe is installed, and also strengthens the protection of water flow transportation. The design is easy to use and solves the problem that the spacing between the two steel pipes cannot be adjusted after connection, vibration occurs after directly connecting to the water source, and long-term use easily causes wear of the steel pipe connection.

[0024] Among them, each locking member 104 is respectively located on one side of the corresponding card plate 101, each limiting member 102 is respectively located on one side of the corresponding card plate 101, each supporting plate 107 is respectively located on one side of the corresponding buffer spring plate 106, and the other side of each buffer spring plate 106 is respectively located on both sides of the isolation ring 105, and the isolation ring 105 is located on the inner side of the corresponding card plate 101. When a steel pipe passes through both sides of the isolation ring 105, the inner end of the steel pipe is in contact with the corresponding supporting plate 107. Since a buffer spring is provided in the buffer spring plate 106, the vibration generated during the installation of the steel pipe and when it is used can be eliminated. The buffer spring plate 106 and the supporting plate 107 also have sealing rings, which can prevent the overflow of water passing through the steel pipe. Even if the sealing effect fails, a water guide groove is also provided in the plate body 108, which can also prevent water from overflowing from the two plate bodies 108.

[0025] Secondly, the two side plates 110 are respectively located on both sides of the plate body 108, and the two side ears 109 are respectively located on the other two sides of the plate body 108. The upper end of the limiting column 113 is located below the movable block 112, and the upper part of the movable block 112 is located at the lower end of the thrust spring 111. The upper end of the thrust spring 111 is located on the inner side of the side plate 110. After the steel pipe is abutted against the corresponding limiting column 113, due to the existence of the thrust spring 111, the movable block 112 and the limiting column 113 will continue to apply pressure, keeping each limiting column 113 against the outer surface of the steel pipe, so that different specifications of steel pipes can be connected, thereby improving the overall connection applicability of the equipment and realizing the connection of steel pipes of different sizes at both ends.

[0026] At the same time, the locking cap 115 is located at one end of the locking nut 114, and the locking nut 114 is located above the corresponding side ear 109. After the pipeline is connected, the locking nut 114 and the locking cap 115 are tightened to tightly connect the two plates 108 to maintain airtightness, thereby completing the connection work of the steel pipe.

[0027] In this embodiment, the support plate 107 provided now cooperates with the buffer spring plate 106 to provide buffer support after the steel pipe is installed, and also strengthens the protection of water flow transportation. This design is easy to use and solves the problem that the two steel pipes cannot adjust the distance after connection, generate vibration after directly connecting to the water source, and easily cause wear of the steel pipe connection after long-term use. When steel pipes pass through both sides of the isolation ring 105, the inner end of the steel pipe contacts the corresponding support plate 107. Since the buffer spring plate 106 is provided with a buffer spring, the vibration generated during the installation of the steel pipe and during use can be eliminated. The buffer spring plate 106 and the support plate 107 also have sealing rings, which can prevent the overflow of water passing through the steel pipe. Even if the sealing effect fails, the plate body 108 is provided with a water guide groove, which can prevent water from overflowing from the two plate bodies 108. After the steel pipe is abutted against the corresponding limit column 113, due to the existence of the thrust spring 111, the movable block 112 and the limit column 113 will continue to apply pressure to keep each limit column 113 against the outer surface of the steel pipe, so that steel pipes of different specifications can be connected, thereby improving the overall connection applicability of the equipment and realizing the connection of steel pipes of different sizes at both ends. After the pipeline is connected, tighten the locking nut 114 and the locking cap 115 to tightly connect the two plate bodies 108 to maintain airtightness and complete the connection of the steel pipe.

The other end of each mounting rod 202 is fixedly connected to the screening ring 203 and is located on one side of the screening ring 203. Each mounting ring 201 is fixedly connected to the corresponding side plate 110 and is located on one side of the corresponding side plate 110. The mounting ring 201 provides mounting support for the corresponding mounting rod 202. The length of the mounting rod 202 is adjusted accordingly according to the size of the steel pipe actually produced and connected. The presence of the screening ring 203 can check the size of the steel pipe before the steel pipe is connected. If the steel pipe can pass through the screening ring 203 smoothly, it proves that the steel pipe can be connected under the support of the two plate bodies 108 and the plurality of limiting columns 113. If it cannot pass through the screening ring 203, it means that the size of the steel pipe exceeds the maximum size that can be covered by the two plate bodies 108 and each limiting column 113.

[0032] In this embodiment, the mounting ring 201 provides mounting support for the corresponding mounting rod 202. The length of the mounting rod 202 is adjusted accordingly according to the size of the steel pipe actually produced and connected.

If the steel pipe can pass through the screening ring 203 smoothly, it proves that the steel pipe can be connected under the support of the two plates 108 and multiple limit columns 113. If it cannot pass through the screening ring 203, it means that the size of the steel pipe exceeds the maximum size that can be covered by the two plates 108 and each limit column 113.
