[0025] When it is necessary to insert pipe 2 into pipe 1 for connection, first sleeve the sleeve 3 on the left end of the outer surface of pipe 2, and insert the lifting rod 20 into pipe 1.
[0026] There are multiple groups of support column 1 7, support sleeve 1 8 and spring 1 9, which are dispersed in a ring shape. There are multiple groups of support column 2 12, support sleeve 2 11 and spring 2 13, which are dispersed in a ring shape. A wedge block 2 14 is fixedly installed on the upper end of the support column 2 12, and a wedge block 10 is fixedly installed on the left end of the transmission ring 6 corresponding to the wedge block 2 14.
[0027] Then, the threaded ring 5 is manually twisted, and the threaded ring 5 is spirally connected with the threaded groove 4 on the casing 3. As the threaded ring 5 rotates, it can be displaced to the left on the outer surface of the casing 3. When the threaded ring 5 moves, it will carry the wedge block 14 to move to the left.
[0028] A support member 15 is fixedly mounted on the left side of the outer surface of the sleeve 3 , and a transmission rod 16 is rotatably connected to the upper end of the support member 15 .
[0029] A notch 17 is provided at the left end of the wedge block 14, a fixed shaft 19 is fixedly installed inside the notch 17, a slide groove 18 is provided at the right end of the transmission rod 16, the fixed shaft 19 is slidably connected to the slide groove 18, a tilting rod 20 is fixedly installed at the left end of the transmission rod 16, and the support member 15, the transmission rod 16, the wedge block 10, the wedge block 14, the notch 17, the fixed shaft 19, the slide groove 18 and the tilting rod 20 are correspondingly arranged in multiple groups and are dispersedly arranged in a ring shape.
[0030] The wedge block 10 and the wedge block 2 14 collide and displace with each other, so that the wedge block 2 14 moves downward under the action of the support column 2 12, the support sleeve 2 11 and the spring. The downward displacement of the wedge block 2 14 synchronously drives the transmission rod 16 to deflect counterclockwise around the support member 15, and the tilting rod 20 at the other end of the transmission rod 16 will tilt the pipe mouth of the pipe 1 outward to expand the pipe mouth, and then the pipe 2 2 can be inserted into the pipe 1 to complete the installation.
[0031] The existing flared joint is to expand the end of the pipe to form a trumpet shape, and a bushing is set between the two pipes when connecting. The outer surface of the bushing is adapted to the trumpet-shaped inner wall of the flared part, and the inner diameter of the bushing is the same as the inner diameter of the pipe, so that the bushing is used to complete the sealing between the two pipes, and finally the flanges or pressure flanges on the two pipes are connected with bolts to complete the connection of the two pipes. However, due to process limitations, the bushing and the steel-plastic composite pipe cannot be completely sealed. The existing processing method is often to set a sealing ring made of elastic material on the bushing. Since the surface of the bushing is an inclined surface, the sealing ring needs to withstand radial pressure and axial pressure at the same time, and it is very easy to deform or damage and affect the sealing of the pipe connection. Therefore, the utility model sets a lifting rod 20, and uses the manual rotation of the threaded ring 5 to drive the corresponding lifting rod 20, so that the lifting rod 20 is inserted into the pipe 1, the pipe mouth of the pipe 1 is enlarged, and the connection between the pipe 1 and the pipe 2 2 is convenient, which relatively improves the convenience of the equipment.
[0032] Working principle: when it is necessary to insert pipe 2 into pipe 1 for connection, first sleeve the sleeve 3 on the left end of the outer surface of pipe 2, and insert the tilting rod 20 into pipe 1, then manually twist the threaded ring 5, the threaded ring 5 is spirally connected with the threaded groove 4 on the sleeve 3, and as the threaded ring 5 rotates, it can be displaced to the left on the outer surface of the sleeve 3, and the threaded ring 5 will carry the wedge block 2 14 to move to the left while moving, the wedge block 10 and the wedge block 2 14 collide and displace with each other, so that the wedge block 2 14 moves downward under the action of the support column 2 12, the support sleeve 2 11 and the spring, and the downward displacement of the wedge block 2 14 synchronously drives the transmission rod 16 to deflect counterclockwise around the support member 15, and the tilting rod 20 at the other end of the transmission rod 16 will tilt the pipe mouth of pipe 1 outward to expand the pipe mouth, and then pipe 2 2 can be inserted into pipe 1 to complete the installation.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
