Description

Technical Field

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

[0002] A clamp is a connector that connects grooved pipes, valves and pipe accessories. It is used as a tightening clamp between pipe joints. The bolts and nuts on the clamp can be used to fasten the clamp and the pipe. When the clamp is used on a drain pipe, the interface between the pipes is first sealed with a pipe bundle with a rubber ring, and then the pipe is fixed outside the rubber ring with a clamp to prevent excessive pressure on the pipe from moving left and right and leaking.

[0003] The clamps of the prior art can achieve the connection of water supply and drainage pipes well, but there are still some shortcomings. For example, the clamps only rely on bolt connection to control their freedom, which can easily cause relative displacement between the upper and lower clamps, thereby causing a certain impact on the sealing ring and interface inside, increasing the risk of connection failure and the possibility of water leakage and air leakage. In particular, the clamps can only maintain a certain locking force after clamping. When the two pipes are forced to move outward, the clamps cannot maintain good clamping, which leads to leakage of liquid between the two pipes.

[0004] However, traditional clamps need to be fastened with bolts and nuts, which are easy to lose, and installation and removal require workers to hold professional tools such as pliers, which makes installation slow. Utility Model Content
