[0002] Steel pipes are a common type of metal pipe, widely used in fields such as construction, machinery, petroleum, and chemical industry. There are many types of steel pipes, and threaded pipes belong to one type of steel pipe. During the production and processing of threaded pipes, a clamping structure is required to clamp and fix them for processing.

[0003] A stainless steel pipe clamping mechanism (authorized announcement number: CN213163952U) is disclosed in the patent library. It includes a support base. A sliding groove is opened in the support base, and a sliding block is slidably connected in the sliding groove. A supporting base is welded and fixed to the top of the sliding block. A screw rod is threadedly connected in the sliding block, and the screw rod is rotatably connected to the support base. A fixed block is fixed to the top of the supporting base, and a U-shaped frame is rotatably connected to the top of the fixed block. A semi-circular clamping groove for clamping the steel pipe is opened in the fixed block. The cylinder block of a cylinder is fixed to the U-shaped frame, and a pressing plate is connected and fixed to the end of the piston rod of the cylinder. An arc-shaped pressing groove is opened on the side of the pressing plate close to the fixed block. When this stainless steel pipe clamping mechanism is in use, the pipe fittings are fixed stably and are not prone to loosening, and the fixed pipes can be flexibly adjusted in position as needed.

In this example, the clamping mechanism also includes a threaded barrel 7, which is rotatably embedded and installed on the outer side of the clamping seat 5, and the threaded barrel 7 is symmetrically provided with several screws. The inner side of the threaded barrel 7 is threadedly connected with a screw rod 2 8, and both ends of the screw rod 2 8 extend to the outer side of the threaded barrel 7, and the lower end of the screw rod 2 8 is movably connected with a clamping plate 9 in the clamping seat 5. The outer wall of the clamping plate 9 is symmetrically provided with a guide rod 10, and the end of the guide rod 10 away from the clamping plate 9 passes through the side wall of the clamping seat 5. The outer wall of the upper end of the threaded barrel 7 is sleeved with a bevel gear 11, and the bevel gear 11 is meshed with one side of the double-sided gear ring 12. The clamping mechanism can synchronously drive multiple screw rods 2 8 to rotate, thereby driving the clamping plate 9 to synchronously move toward or away from the center of the clamping seat 5, so that it can be adapted to be used for clamping and fixing pipes of different diameters and specifications, and can clamp and fix them tightly, which is easy to use, has a wider range of applications, and is more practical. In this example, the connecting assembly includes screw rod three 15, and screw rod three 15 is rotatably installed in a symmetrical position inside the connecting plate 4. Two groups of left-right symmetrical sliding grooves 17 are symmetrically opened on the top of the connecting plate 4, and the sliding grooves 17 correspond to the screw rod three 15.

It can be adapted to clamp and fix pipes of various specifications, sizes and diameters, and has a wider range of applications. When the position of the pipe needs to be adjusted, the screw rod 2 can be driven to rotate by the hand crank, and then the slide seat 3 can be adjusted to drive the connecting plate 4 and the clamping seat 5 to move left and right, so as to adjust the position of the clamped pipe and facilitate its processing. In addition, when the clamping seat 5 and its connecting structure need to be disassembled, maintained, repaired or replaced as a whole, the handle can be twisted to drive the screw rod 3 15 to rotate, so that the screw rod 3 15 drives the two connecting blocks 16 to move synchronously to the relative outsides. After the connecting block 16 moves to the relative outermost sides of the two slide grooves 17, the clamping seat 5 can be moved up to move the connecting block 16 out of the fixing groove 18 to complete its disassembly. It is easy to use and more practical.
