Description

Technical Field

[0001] The utility model relates to the field of pipe clamps, in particular to a pipe clamp with a quick locking mechanism. Background Art

[0002] Pipe wrenches, also known as pipe spanners, are primarily used to tighten and loosen threaded joints in pipe connections to ensure tightness and sealing of pipe connections and prevent water leakage. They are specialized tools widely used in a variety of situations. The quick-locking mechanism ensures that the jaws remain stable after clamping the pipe to prevent loosening during operation.

[0003] Among the existing pipe pliers with a quick locking mechanism, the most common ones are manual pipe pliers consisting of a plier handle and a chain, which means that the pipe pliers lack a locking structure. When the bolt is locked during use, the adjustment structure of the pipe pliers is likely to loosen, reducing the clamping force of the pipe pliers, affecting the performance of the pipe pliers and easily causing friction damage to the plier head, thereby shortening the service life of the pipe pliers.

[0004] Therefore, the present invention provides a pipe clamp with a quick locking mechanism to solve the above problems. Utility Model Content

The lower locking block 4 and the upper locking block 7 fix the adjusting block 3 to prevent the adjusting block 3 from moving. The internal clamping block 8 of the upper locking block 7 is placed on the top of the adjusting block 3, and the spring 11 provides a downward pulling force to the top plate 10, so that the spring 11 drives the top plate 10 to move downward and then drives the clamping block 8 through the connecting rod 9 to clamp and fix the adjusting block 3. Example

[0024] On the basis of embodiment 1, in order to facilitate the lifting and lowering of the clamping block 8 and the adjustment block 3 to adjust the position of the pliers head 2, a fixing rod 15 is installed on the top of the upper locking block 7, and a clamping ring 16 is installed on the outer surface of the fixing rod 15. The clamping ring 16 is placed around the outer surface of the top plate 10, and a rotating block 12 is installed at the top center of the top plate 10. A cross bar 13 is installed through the side wall of the rotating block 12, and a paddle 14 is fixedly installed at both ends of the cross bar 13.

The rotating block 12 can drive the paddle 14 on the outer surface of the clamp ring 16 through the cross bar 13. The shape of the clamp ring 16 is elliptical. , rotating the paddle 14 can drive the opening and closing of the clamp ring 16. When the clamp ring 16 is closed, the top plate 10 can be moved upward through the arc inside the ring, thereby driving the clamping block 8 to move upward and move away from the top of the adjusting block 3, making it convenient to adjust the position of the pliers head 2 of the adjusting block 3 from the adjusting slot 5. The paddle 14 is rotated to make the clamp ring 16 open. Under the action of the downward pulling force provided by the spring 11, the top plate 10 is driven by the spring 11 to move downward, and then the clamping block 8 is driven by the connecting rod 9 to clamp and fix the adjusting block 3.
