Description

Technical Field

[0001] The utility model relates to the field of clamps, and particularly relates to a clamp with stable anti-deformation performance. Background Art

[0002] A clamp is a connecting device for connecting grooved pipe fittings, valves and pipeline accessories, and is used for tightly connecting between quick joints. Generally, the joints are provided with gaskets, rubber, silica gel and PTFE, which have good performance, high sealing degree and simple installation. In the prior art, the Chinese utility model patent with the publication number: CN221042198U discloses an anti-deformation cable clamp device. This utility model can increase the strength of two clamps to make them not easily deformed, and also facilitate connecting the two clamps together, which is convenient and fast.

[0003] However, adding arc-shaped rods and arc-shaped grooves to the two clamps requires grooving the clamps, which reduces the stability of the clamps, making the increased strength of the arc-shaped reinforcing ribs reduced. And a bolt-locking nut is arranged on the nut. Although it can make the nut structure stable, this stability depends on the fixed connection of the bolt, and both the bolt and nut structures are prone to loosen due to the vibration of the fluid in the pipeline. Therefore, improvement is needed. Summary of the Utility Model

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0021] As Figure 1 , Figure 2 and Figure 3 shown, a stable anti-deformation clamp includes a first arc-shaped hoop 1. A second arc-shaped hoop 2 is fixedly connected to the side position of the first arc-shaped hoop 1. A sealing ring 3 is movably connected to the inner side positions of the first arc-shaped hoop 1 and the second arc-shaped hoop 2. First connecting blocks 4 are fixedly connected to both ends of the first arc-shaped hoop 1. Second connecting blocks 5 are fixedly connected to both ends of the second arc-shaped hoop 2. Arc-shaped reinforcing plates 6 are fixedly connected to the side positions of the first arc-shaped hoop 1 and the second arc-shaped hoop 2. A reinforcing connecting plate 7 is fixedly connected between the arc-shaped reinforcing plate 6 and the first arc-shaped hoop 1 or the second arc-shaped hoop 2. A reinforcing bolt 9 is movably installed in the reinforcing connecting plate 7. A reinforcing screw hole 8 is formed in the reinforcing connecting plate 7. One end of the reinforcing screw hole 8 penetrates through the arc-shaped reinforcing plate 6, and the other end penetrates through the first arc-shaped hoop 1 or the second arc-shaped hoop 2. The reinforcing bolt 9 is movably installed in the reinforcing screw hole 8. Both ends of the arc-shaped reinforcing plate 6 are fixedly connected to the first connecting block 4 or the second connecting block 5. The arc-shaped reinforcing plate 6 is located outside the first arc-shaped hoop 1 and the second arc-shaped hoop 2, and another arc-shaped clamp structure is formed on the outside of the first arc-shaped hoop 1 or the second arc-shaped hoop 2. The arc-shaped reinforcing plate 6 is connected to the first arc-shaped hoop 1 or the second arc-shaped hoop 2 through the reinforcing connecting plate 7, so that the strength of the clamp is increased and it is more difficult to deform. At the same time, a reinforcing bolt 9 is arranged in the reinforcing connecting plate 7, and the reinforcing bolt 9 can be screwed inward, so that the lower end of the reinforcing bolt 9 presses the pipelines and pipe fittings inside the sealing ring 3, making the connection of the pipelines and pipe fittings more stable and not easy to break away.

[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a storage groove 12 is formed in the second connecting block 5. An active block 14 is movably installed in the storage groove 12. A limiting block 15 is fixedly connected to the side position of the active block 14. The first connecting block 4 and the second connecting block 5 are fixedly connected to the screw rod 19. One end of the screw rod 19 is fixedly connected with a cover plate 20. A positioning rod 11 is fixedly connected to the first connecting block 4. Mounting holes 10 are formed in the first connecting block 4 and the second connecting block 5. The screw rod 19 is movably installed in the mounting holes 10 of the first connecting block 4 and the second connecting block 5. A positioning hole 21 is formed in the cover plate 20. The cover plate 20 is movably installed with the positioning rod 11 through the positioning hole 21. The other end of the screw rod 19 is threadedly connected with a nut 22. A positioning plate 23 is fixedly connected to the side position of the nut 22. An activity groove 13 is formed in the second connecting block 5. The activity groove 13 communicates with the storage groove 12. An activity rod 16 is fixedly connected to the side position of the active block 14. One end of the activity rod 16 extends out of the storage groove 12 and is fixedly connected with a pull head 17. A spring 18 is movably installed in the storage groove 12. The spring 18 is sleeved on the activity rod 16 and is located at the side position of the active block 14. The limiting block 15 is movably installed in the activity groove 13. Pull the pull head 17 to the side, so that the pull head 17 pulls the activity rod 16 and the active block 14 to move to the side. The active block 14 moves to the side in the storage groove 12, thereby squeezing the spring 18 at the side position. The movement of the active block 14 to the side pulls the limiting block 15 to the side, making it convenient to install the nut 22. After the nut 22 is tightened, the positioning plate 23 presses against the second connecting block 5, and then release the pull head 17, so that the spring 18 pushes the active block 14 and the limiting block 15 to reset, so that the limiting block 15 catches the positioning plate 23, making the installation of the nut 22 more stable and not easy to loosen.

[0023] It should be noted that the utility model is a stable and anti-deformation clamp, in which an arc-shaped reinforcing plate 6 is fixedly connected to the outer sides of the No. 1 arc-shaped hoop 1 and the No. 2 arc-shaped hoop 2, and the arc-shaped reinforcing plate 6 is fixedly connected to the No. 1 arc-shaped hoop 1 or the No. 2 arc-shaped hoop 2 through a reinforcing connecting plate 7, so that the No. 1 arc-shaped hoop 1 and the No. 2 arc-shaped hoop 2 have higher strength and are not easy to deform. The reinforcing bolt 9 is screwed inward to move the lower end of the reinforcing bolt 9 inward, thereby squeezing the No. 1 sealing ring 3 inward, so that the pipes and pipe fittings fixedly connected in the sealing ring 3 are more tightened and not easy to fall off. When the No. 1 arc-shaped hoop 1 and the No. 2 arc-shaped hoop 2 are closed to each other, the screw 19 is passed through the mounting holes 10 of the No. 1 connecting block 4 and the No. 2 connecting block 5, and the cover plate 20 By movably installing the positioning rod 11 through the positioning hole 21, the pull head 17 is pulled outward, the movable block 14 moves synchronously and compresses the spring 18 on the side. After the limiting block 15 moves to the side position, the nut 22 is installed on the screw rod 19 through an external wrench, and the nut 22 is tightened so that the positioning plate 23 presses the No. 2 connecting block 5. Then the pull head 17 is released, so that the compressed spring 18 is restored to open, pushing the movable block 14 to move in the opposite direction, and the limiting block 15 moves to the side. The limiting block 15 moves in the opposite direction to the outer position of the positioning plate 23, and the positioning plate 23 is stuck, so that the positioning plate 23 cannot move outward, making the nut 22 more firmly installed, and the No. 1 arc hoop 1 and the No. 2 arc hoop 2 are firmly connected and not easy to loosen.
