Technical realization elements of toothless flexible clamping pipe wrench

Technical realization elements:

3. The purpose of this utility model is to solve the problems in the prior art, and provide a method that can complete the installation and disassembly of pipeline connections without damaging the organic coating on the surface of the pipeline connections, and avoid waste of labor and materials , A toothless flexible clamping pipe wrench that can be repeatedly rotated once stuck on the pipeline connector, and is easy to use and operate.

4. The technical scheme of the utility model is:

5. A toothless flexible pipe clamp, comprising a movable jaw 2, a fixed jaw 3, a positioning pawl 5, a locking pawl 8 and a connecting part, one end of the movable jaw 2 and the fixed jaw 3 One end of the movable jaw 2 is rotatably connected, the outer side of the other end of the movable jaw 2 is involute tooth shape, the end of the fixed jaw 3 away from the movable jaw 2 is connected with the connecting part, and the positioning pawl 5 is rotatably arranged at the connection On the other hand, both the movable jaw 2 and the fixed jaw 3 are provided with a flexible pad 4. The flexible pad 4 enables the movable jaw 2 and the fixed jaw 3 to clamp the workpiece flexibly, without slipping, and rotating the workpiece without damaging the surface of the workpiece.

6. As a preferred technical solution, one end of the movable jaw 2 and one end of the fixed jaw 3 are rotatably connected by a first cylindrical shaft 1.

7. As a preferred technical solution, the connecting portion includes a first connecting plate 13 and a second connecting plate 14, and the first connecting plate 13 and the second connecting plate 14 are connected by a bolt 7 and a nut 17.

8. As a preferred technical solution, the fixed jaw 3 is connected with a fixed rod 9 and the fixed rod 9 is connected with a fixed rod handle 12.

9. As a preferred technical solution, a movable hollow block 18 is rotatably provided on the connecting portion, the movable hollow block 18 is connected with the movable rod 10, and the movable rod 10 is connected with the movable rod handle 11.

10. As a preferred technical solution, the locking pawl 8 is rotatably arranged on the movable hollow block 18 through a second cylindrical rotating shaft 16, and the locking pawl 8 is connected to one end of the second torsion spring 15 , The other end of the second torsion spring 15 is connected to the movable hollow block 18.

11. As a preferred technical solution, the positioning pawl 5 is connected to one end of the first torsion spring 6, and the first torsion

The other end of the spring 6 is connected to the connecting portion.

12. As a preferred technical solution, internal teeth are provided inside the movable jaw 2 and the fixed jaw 3, and the flexible pad 4 is provided on the internal teeth. The internal teeth can prevent the flexible pad 4 from shifting.

13. As a preferred technical solution, the flexible pad 4 is made of a rubber composite material.

14. The beneficial effects of this utility model are as follows: (1) The installation and disassembly of the pipeline connection can be completed without damaging the organic coating on the surface of the pipeline connection, and the waste of labor and materials can be avoided. (2) It can be rotated repeatedly when stuck on the pipeline connector once. (3) Reasonable design, simple structure, easy manufacturing, convenient use and operation, time-saving and labor-saving, fast and stepless expansion and contraction, greatly reducing the labor intensity of the operator.
