[0003] Currently, when testing the pressure of a pipeline section, the pressure gauge is usually fixedly connected to the ball valve at the pipeline. Traditional pressure gauges are mainly installed by tightening the threads and then fixing them with fixing bolts. When it is necessary to disassemble and replace the pressure gauge, the operation is cumbersome and affects the convenience of disassembling the pressure gauge. To solve the above technical problems, we designed a clamping structure for fixing the pressure gauge. Summary of the Invention

[0004] The purpose of this invention is to provide a clamping structure for fixing a pressure gauge, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: A clamping structure for fixing a pressure gauge includes a pressure gauge body and a pipe section valve body. The bottom end of the pressure gauge body is provided with an integral pressure gauge assembly joint. The center of the top end of the pipe section valve body is provided with an assembly screw hole adapted to the pressure gauge assembly joint. The pressure gauge assembly joint is threaded to the inside of the assembly screw hole. The top of both sides of the pressure gauge assembly joint is provided with a slot.

One end of the threaded push rod is in contact with the center of one side of the corresponding convex slider.

[0007] In the above-mentioned clamping structure for fixing a pressure gauge, sealing gaskets are fixedly provided at the top and bottom of the inner wall of the semi-circular clamping block, and the sealing gaskets are in contact with the surface of the pressure gauge assembly joint.

[0008] In the above-mentioned clamping structure for fixing a pressure gauge, the semi-circular clamping block has a cavity inside, and a connecting plate is nested inside the cavity.

[0009] In the above-mentioned clamping structure for fixing a pressure gauge, a connecting rod is fixedly provided at the top of the connecting plate, and the top of the connecting rod passes through the top wall of the cavity and extends to the outside where a pull ring is fixedly provided.

[0010] In the above-mentioned clamping structure for fixing a pressure gauge, the surface of the pull ring is fitted with a rubber ring, and the surface of the rubber ring is provided with uniformly distributed anti-slip texture.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-4 As shown, this utility model discloses a clamping structure for fixing a pressure gauge, including a pressure gauge body 1 and a pipe section valve body 2. The bottom end of the pressure gauge body 1 is provided with an integral pressure gauge assembly connector 7. The center of the top end of the pipe section valve body 2 is provided with an assembly screw hole 15 that is adapted to the pressure gauge assembly connector 7. The pressure gauge assembly connector 7 is threaded to the inside of the assembly screw hole 15. The top of both sides of the pressure gauge assembly connector 7 is provided with a slot 8. Semi-circular clamping blocks 5 are slidably connected to both sides of the assembly screw hole 15. The inner walls of the two semi-circular clamping blocks 5 are fixed with a locking block 9, and the locking block 9 is engaged with the corresponding locking slot 8.

[0019] Specifically, after the pressure gauge body 1 is threadedly fixed to the assembly screw hole 15 via the pressure gauge assembly joint 7, the top of the pressure gauge assembly joint 7 is clamped and fixed by the semi-circular clamping block 5. This not only improves the firmness of the connection of the pressure gauge body 1, but also eliminates the need to disassemble the bolts when repairing and replacing the pressure gauge, effectively improving the convenience of pressure gauge repair and replacement.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a clamping structure for fixing a pressure gauge. The top of the pipe section valve body 2 has convex grooves 3 on both sides. The interior of the two convex grooves 3 is slidably connected to convex sliders 16. The top of the two convex sliders 16 is fixedly connected to the center of the bottom of the semi-circular clamping block 5. The groove wall on one side of the two convex grooves 3 is threaded with a threaded push rod 4. One end of the threaded push rod 4 is in contact with the center of one side of the corresponding convex slider 16.

[0021] Specifically, the threaded push rod 4 pushes the convex slider 16 to move, and the convex slider 16 drives the semi-circular clamping block 5 to move. The semi-circular clamping block 5 can clamp the pressure gauge assembly joint 7. At the same time, the locking block 9 inside the semi-circular clamping block 5 engages with the locking groove 8 opened on the surface of the pressure gauge assembly joint 7, further improving the stability of the pressure gauge assembly joint 7 assembly.

[0022] Sealing gaskets 10 are fixedly provided at the top and bottom of the inner wall of the semi-circular clamping block 5, and the sealing gaskets 10 are in contact with the surface of the pressure gauge assembly joint 7.

[0023] Specifically, the sealing gasket 10 improves the sealing performance of the connection.

[0024] The semi-circular clamping block 5 has a cavity 11 inside, and a connecting plate 12 is nested inside the cavity 11. Multiple limiting posts 13 are fixed at equal intervals at the bottom end of the connecting plate 12. Multiple limiting holes 14 are opened at equal intervals along the circumference on the outer side of the mounting screw hole 15. The multiple limiting posts 13 pass through the cavity 11 and are nested and connected with the corresponding limiting holes 14.

[0025] A connecting rod is fixedly provided at the top of the connecting plate 12. The top of the connecting rod passes through the top cavity wall of the cavity 11 and extends to the outside where a pull ring 6 is fixedly provided.

[0026] The surface of the pull ring 6 is fitted with a rubber ring, and the surface of the rubber ring is provided with evenly distributed anti-slip texture.

[0027] Specifically, the connecting plate 12 is raised and lowered by pulling the ring 6, and the raising and lowering of the connecting plate 12 drives the raising and lowering of the limiting post 13, so that the limiting post 13 and the limiting hole 14 can be nested and separated.

[0028] In specific implementation, when the pressure gauge is assembled with the pipe section valve body 2, the pressure gauge assembly connector 7 is first screwed into the assembly screw hole 15. Then, the threaded push rods 4 on both sides of the pipe section valve body 2 are manually rotated. The threaded push rods 4 push the convex slider 16 to move. The convex slider 16 drives the semi-circular clamping blocks 5 to move, so that the inner walls of the two semi-circular clamping blocks 5 contact the surface of the pressure gauge assembly connector 7. When the inner walls of the semi-circular clamping blocks 5 contact the surface of the pressure gauge assembly connector 7, the locking block 9 is nested into the slot 8. At the same time, the limiting post 13 at the bottom of the semi-circular clamping block 5 is aligned with the limiting hole 14. The limiting post 13 falls into the limiting hole 14 by its own weight, further limiting and fixing the semi-circular clamping block 5, thereby improving the stability of the installation of the pressure gauge body 1 and the pipe section valve body 2.

[0029] When repairing or replacing the pressure gauge, manually pull the pull ring 6 to separate the limiting post 13 from the limiting hole 14. Then, manually rotate the threaded push rod 4 in the opposite direction to separate it from the convex slider 16. This facilitates the separation of the two semi-circular clamping blocks 5 from the pressure gauge assembly joint 7, allowing for quick disassembly of the pressure gauge without the need for wrenches and screwdrivers, thus improving the convenience of disassembling and maintaining the pressure gauge body 1.
