Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to an anti-seismic clamp. Background Art

[0002] A clamp is a connection device that connects grooved pipes, valves and pipeline accessories. It is used to tighten quick connectors. Generally, the two connectors are equipped with gaskets, rubber, silicone and PTFE. Due to its good performance, high sealing and easy installation, the clamp connection technology has become the preferred technology for current liquid and gas pipeline connections. It has gradually replaced traditional pipeline connection methods such as flange connection and welding connection. It is not only more mature in technology, but also has a wider market application.

[0003] However, the inner wall of the existing clamp does not have an anti-seismic component. Under the action of external stress, the clamp will be twisted and deformed, thereby affecting the sealing between the pipes. In addition, the connecting parts that fix the clamp are exposed to the outside and are easily corroded and rusted, which increases the difficulty of subsequent disassembly. For this reason, an anti-seismic clamp is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an anti-seismic clamp.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: an anti-seismic clamp, comprising a first hoop body and a second hoop body, a first connecting ear is fixedly provided on both sides of the first hoop body, a second connecting ear is fixedly provided on both sides of the second hoop body, the inner walls of the first hoop body and the second hoop body are each provided with two card grooves, the inner walls of the first hoop body and the second hoop body are each provided with an anti-seismic component, two slots are provided on the top of the first connecting ear, a positioning hole is provided on the front inner wall of the slot, and a protective structure is provided on the top of the two first connecting ears.

[0006] As a further description of the above technical solution:

A storage cavity is provided in the plug-in plates. A positioning rod is movably provided in the storage cavity.

[0012] As a further description of the above technical solution:

[0013] A through slot is provided on the top of the insertion plate, and the through slot is communicated with the storage cavity. A vertical plate is fixedly provided on the top of the positioning rod, and the vertical plate passes through the through slot and is fixedly provided with a pull handle. A spring is fixedly provided on the inner wall of one side of the storage cavity, and the other end of the spring is fixedly connected to one end of the positioning rod.

[0014] As a further description of the above technical solution:

Compared with the existing technology, the seismic clamp is provided with a protective cover, an insert plate, a storage cavity, a through slot, a spring, a positioning rod and a vertical plate. After the clamp is installed, the two vertical plates are squeezed inward, and the vertical plates drive the positioning rod to retract into the storage cavity. The insert plate is inserted into the slot, and then the vertical plate is released. The thrust of the spring can restore the position of the positioning rod, so that one end of the positioning rod pops out from the positioning hole to realize the installation of the protective cover.
