In the figure: 1. a clamp body; 11. an arc-shaped member; 12. a wing plate; 13. a groove I; 14. a second groove; 2. riveting a nut; 3. and (3) sealing rings.

Detailed Description

Referring to fig. 1 to 3, in an embodiment of the present invention, a clip structure includes a clip member formed by two clip bodies 1, and a sealing ring 3 and a press riveting nut 2 are disposed on the clip member. Wherein, the press riveting nut 2 comprises a plurality of press riveting nuts. The clamp body 1 is composed of an arc-shaped piece 11, a wing plate 12, a first groove 13 and a second groove 14. Wherein, the wing plate 12, the first groove 13 and the second groove 14 comprise two. The press riveting nuts 2 are fixedly connected to the clamp body 1 above.

The plurality of wing plates 12 are respectively arranged on the front side and the rear side of the arc-shaped piece 11, and the wing plates 12 and the arc-shaped piece 11 are integrally arranged. And further, the steel plate is formed by one-time stamping of alloy steel materials.

The first groove 13 and the second groove 14 are both arranged on the inner wall of the arc-shaped piece 11. Two grooves 14 are respectively positioned on two sides of the groove one 13. The sealing ring 3 is arranged in the first groove 13, the sealing ring 3 adopts an X-shaped structure, and an annular groove is formed in the inner wall of the sealing ring for buffering the stress during installation. The second groove 14 is used for corresponding to the protruding part arranged on the connected pipe body.

Each wing plate 12 is provided with a plurality of holes, and a plurality of press riveting nuts 2 are respectively arranged in the corresponding holes. The press riveting nut 2 adopts embedded press riveting in the hole. The two clamp bodies 1 are connected through a fastening bolt matched with a press riveting nut 2.

The working principle of the invention is as follows: the clip body 1 is manufactured by one-time press forming with an alloy steel material. The two clip bodies 1 are punched to form a clip member. Then, the drilling device is used for opening corresponding holes on the corresponding wing plates 12 on each clamp body 1. After the holes are formed, a plurality of press riveting nuts 2 are arranged in the corresponding holes formed in the upper clamp body 1. When the clamp structure is used, the two clamp bodies 1 are mutually matched and sleeved on the pipe body to be connected, the sealing ring 3 is matched, and then the fixed assembly of the two clamp bodies 1 is realized in an assembly mode of assembling the press riveting nut 2 through the fastening bolt. Thereby realizing the convenience connection of the pipe body.

When the clamp structure is disassembled, a plurality of fixing bolts on the clamp structure are disassembled, so that two clamp solids 1 forming the clamp structure are separated, and convenience disassembly operation of the clamp structure is realized.

The foregoing description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical solution of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
