Technical Field

[0001] This utility model relates to the field of pipeline pre-embedding technology, and in particular to a pre-embedded pipeline positioning device. Background Technology

[0002] Chinese patent document CN220320476U discloses a quick-positioning device for pre-embedded pipes, including a base plate, a telescopic component above the base plate, and a fixing component above the base plate. The telescopic component includes a fixing box fixedly installed on the top of the base plate, and a U-shaped frame fixedly installed inside the fixing box on the top of the base plate. A rotating rod with one end penetrating through and extending into the U-shaped frame is rotatably connected to the top of the fixing box, and a rotating handle is fixedly installed on the top of the rotating rod. This quick-positioning device for pre-embedded pipes can adjust the height difference at the connection point of two adjacent pipes by setting the telescopic component, minimizing the height difference at the connection point and making the pipe connection more stable. It also facilitates the connection between adjacent pipes. The fixing component can fix the pipes to prevent displacement after connection, which could lead to detachment or leakage at the connection point.

[0003] The semi-circular clamping plate of the aforementioned pipe pre-embedded quick positioning device has a fixed size and is not easy to disassemble and replace. When it is necessary to fix pipes of different sizes, the semi-circular clamping plate may only have two points of contact with the outer wall of the pipe, making it difficult to form an effective fit and affecting the stability of the pipe positioning. Utility Model Content

The worm is rotatably installed on the front and rear inner walls of the hollow block, and the worm meshes with the worm gear. One end of the worm passes through the hollow block and is fixedly installed with an auxiliary knob. Lifting is controlled by a single threaded rod. Compared with a double-screw lifting mechanism, this method is simpler and faster to assemble, avoids jamming during transmission, and utilizes the self-locking characteristic of the worm gear transmission to prevent the threaded rod from rotating, thus improving the usability and practicality of the device.

[0007] Preferably, the disassembly and assembly mechanism further includes a magnet, a metal sheet, and a lower semi-circular clamping plate. A magnet is embedded in the bottom inner side of the positioning groove, and a metal sheet is fixedly installed at the bottom of the connecting block. The metal sheet and the magnet attract each other, and a lower semi-circular clamping plate is fixedly installed at the top of the connecting block. This facilitates quick replacement of the lower semi-circular clamping plate with the corresponding size according to the pipe size, so that the lower and upper semi-circular clamping plates fit as completely as possible with the outer wall of the pipe, thereby forming an effective fixation. The operation is simple and easy to use, improving the stability of the device for pipe positioning.

[0008] Preferably, an upper semicircular plate is hinged to the top of the lower semicircular plate, and protective pads are provided on the inner walls of both the lower and upper semicircular plates.

[0009] Preferably, a bolt is fixedly installed on the top of the lower semicircular plate, one end of the bolt passes through the upper semicircular plate, and a hexagonal nut is threaded onto the outer wall of the bolt.
