[0020] 3. The present invention provides a concrete pipe pile quick connector, which uses a tool to rotate the adjusting screw sleeve so that the adjusting screw sleeve pulls the threaded pull rod, thereby overlapping the outer wall of the pull plate and the inner wall of one end of the concrete pipe pile. At the same time, the action of tooth one and tooth two is utilized to make one side of tooth one mesh with one side of tooth two, thereby avoiding the problem of sliding at the connection between the inner wall of one end of the concrete pipe pile and the connecting pipe sleeve. When the pull plate is moved, the action of the bracket guide sleeve and the guide rod is utilized to guide the pull plate, thereby avoiding that the pull plate is driven to rotate when the adjusting screw sleeve is rotated, thereby affecting the locking effect of the pull plate on the inner wall of the concrete pipe pile.

[0041] The following is a detailed description of the working principle of the concrete pipe pile quick connector.

[0042] like Figure 1-4 As shown, first, use a tool to adjust the stud 39 so that the stud 39 is connected to the threaded sleeve 38, so that the fixing plate 2 can be fixedly installed on one end of the concrete pipe pile 1, and then, the adjusting roller 26 is rotated by hand or the hexagonal nut 25 is rotated by a tool, so that the distance between the upper and lower clamping plates 21 can be adjusted, so that the positioning protrusion 22 is inserted between the fixing plate 2 and the connecting pipe sleeve 3, thereby achieving the purpose of locking and positioning the fixing plate 2 and the connecting pipe sleeve 3, and using the action of the support spring 24 to push the push plate 23, so that the positioning protrusion 22 can be ejected from the inner cavity of the fixing plate 2 or the connecting pipe sleeve 3, thereby achieving the purpose of removing the clamping plate 21, when the fixing plate 2 and the connecting pipe sleeve 3 are connected, the top of the guide column 34 is inserted into the inner cavity of the guide sleeve 37, and at the same time, using the action of the support elastic tube 35, the positioning push plate 36 is pushed so that one end of the positioning push plate 36 is plugged into the top of the guide column 34, thereby achieving When the screw thread 31 is rotated, the adjusting screw thread 31 is used to pull the threaded pull rod 32, so that the outer wall of the pull plate 33 is overlapped with the inner wall of one end of the concrete pipe pile 1. At the same time, the tooth 1 310 and the tooth 2 311 are used to make one side of the tooth 1 310 mesh with the one side of the tooth 2 311, thereby avoiding the problem of slippage at the connection between the inner wall of one end of the concrete pipe pile 1 and the connecting pipe sleeve 3. When the pull plate 33 is moved, the bracket guide sleeve 312 and the guide rod 313 are used to guide the pull plate 33, thereby avoiding the pull plate 33 from rotating when the adjusting screw thread 31 is rotated, thereby affecting the locking effect of the pull plate 33 on the inner wall of the concrete pipe pile 1, thereby facilitating the connection between the concrete pipe pile 1 and the concrete pipe pile 1.

[0043] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
