[0002] Grooved pipe fittings are a new type of steel pipe connection fittings with pre-set grooves on the top to facilitate cooperation with clamps to achieve quick connection. However, the current pipe fitting connection will produce a problem, that is, when there is water flowing outside the pipe fitting, the water will penetrate into the inside of the clamp sealing ring under strong pressure. During subsequent use, the water will corrode the end of the pipe fitting, which will not only rust the pipe fitting, but also cause galvanic corrosion with the inner tube of the pipe fitting, which will cause damage to the entire pipe fitting, making the pipe fitting unable to continue to be used normally.

[0020] The present invention provides a groove sealing pipe fitting structure, including a pipe fitting body 101, a fixed pipe sleeve 102, two extension blocks 103 and a connecting assembly, wherein the connecting assembly includes two connecting blocks 104, a pipe bracket 105, a fixing bolt 106, a support block 107 and two groups of locking parts, each group of the locking parts includes a threaded sleeve 108, a sealing ring 109, a connecting sleeve 110, a supporting sleeve 111 and a shrinking sleeve 112. The above solution solves the problem that after the groove pipe fitting is connected, the connecting part of the pipe fitting cannot be effectively fixed, and the connecting part is easily loosened due to the impact and shaking of the pipe fitting during pipe operation.

[0021] According to this specific embodiment, the fixed pipe sleeve 102 is detachably connected to the pipe body 101 and is located on the outside of the pipe body 101. The two extension blocks 103 are fixedly connected to the fixed pipe sleeve 102 and are located on both sides of the fixed pipe sleeve 102. The connecting assembly includes two connecting blocks 104, a pipe bracket 105, a fixing bolt 106, a support block 107 and two sets of locking members. The connecting block 104 is detachably connected to the extension block 103 and is located on the outside of the extension block 103. The pipe bracket 105 is fixedly connected to the two connecting blocks 104 and is located below the fixed pipe sleeve 102. The fixing bolt 106 is threadedly connected to the extension block 103 and is located on the outside of the connecting block 104. The fixing bolt 106 passes through the connecting block 104. The support block 107 is fixedly connected to the pipe support 105 and is located below the pipe support 105. The two groups of locking pieces are symmetrically arranged. The locking pieces are fixedly connected to the fixed pipe sleeve 102 and are located on the outside of the fixed pipe sleeve 102. The two pipe bodies 101 are inserted into the fixed pipe sleeve 102, and the pipe bodies 101 on both sides are fixed and locked by the locking pieces. The fixing bolts 106 fix the connecting block 104 to the outside of the extension block 103. The pipe support 105 is attached to the fixed pipe sleeve 102 and provides support for the fixed pipe sleeve 102. The support block 107 is fixed to the working ground with bolts. This method can effectively solve the problem that the connection parts of the pipes cannot be effectively fixed, and the connection parts are easily loosened due to the impact and shaking of the pipes.

[0022] Among them, the threaded sleeve 108 is fixedly connected to the fixed pipe sleeve 102 and is located on the outside of the fixed pipe sleeve 102. The sealing ring 109 is arranged in the threaded sleeve 108. The threaded sleeve 108 is arranged on the outside of the fixed pipe sleeve 102. The sealing ring 109 improves the sealing effect of the connection between the pipe body 101.

[0023] Secondly, the connecting sleeve 110 is threadedly connected to the threaded sleeve 108 and is located on the outside of the threaded sleeve 108. The supporting sleeve 111 is fixedly connected to the connecting sleeve 110 and is located on the outside of the connecting sleeve 110. The connecting sleeve 110 is threadedly connected to the threaded sleeve 108 so that the connecting sleeve 110 is installed on the outside of the threaded sleeve 108, and the connecting sleeve 110 is attached to the fixed pipe sleeve 102. The contact surface between the supporting sleeve 111 and the pipe body 101 is provided with a sealing layer, thereby further improving the airtightness of the locking structure.

[0024] At the same time, the shrink sleeve 112 is slidably connected to the pipe body 101 and is located on the outside of the supporting sleeve 111. The shrink sleeve 112 is arranged in the connecting sleeve 110, and the shrink sleeve 112 is arranged between the threaded sleeve 108 and the supporting sleeve 111. The shrink sleeve 112 is pushed and installed in the threaded sleeve 108 by the supporting sleeve 111, and the shrink sleeve 112 is shrunk and locked according to the size of the pipe body 101, thereby fixing the pipe body 101. The shrink sleeve 112 will resist the sealing ring 109 during installation, causing the sealing ring 109 to deform in the threaded sleeve 108, thereby effectively preventing the pipe body 101 from leaking liquid during use.

[0025] In addition, the threaded sleeve 108 has a mounting groove 113, the connecting sleeve 110 has a groove 114 adapted to the shrink sleeve 112, the sealing ring 109 is arranged in the mounting groove 113, and the supporting sleeve 111 pushes the shrink sleeve 112 to move in the groove 114, so that the shrink sleeve 112 is installed in the mounting groove 113.

[0026] A groove sealing pipe structure of the present embodiment is used, by setting the fixed pipe sleeve 102, the two extension blocks 103 and the connecting assembly. When it is used, the connecting sleeve 110 and the shrink sleeve 112 are sequentially sleeved on the outside of the pipe body 101. After the sleeve is completed, the two pipe bodies 101 are inserted into the fixed pipe sleeve 102, and the connecting sleeve 110 is rotated. The connecting sleeve 110 is threadedly connected with the threaded sleeve 108, and the shrink sleeve 112 is pushed to move by the supporting sleeve 111. The shrink sleeve 112 is shrunk and locked according to the size of the pipe body 101, thereby achieving the two pipe bodies 101. 01, the shrink sleeve 112 presses against the sealing ring 109 in the installation groove 113, causing the sealing ring 109 to deform, thereby improving the sealing performance of the locking structure, and fixing the connecting block 104 to the outside of the extension block 103 by the fixing bolt 106, and the pipe support 105 fits the fixed pipe sleeve 102 and provides support for the fixed pipe sleeve 102, and uses bolts to fix the support block 107 to the working ground, thereby realizing the connection and fixation of the connecting part of the pipe body 101, thereby effectively fixing the connecting part of the groove pipe fitting, preventing the loosening of the connecting part due to the impact and shaking of the pipe fitting, and improving the stability of the pipe fitting during use.
