Description

Technical Field

[0001] This utility model relates to the field of pipe clamp technology, and in particular to a secondary tightening knob for preventing loosening of pipe clamps. Background Technology

[0002] Pipe clamps are common components used to secure pipes in piping systems or mechanical equipment. However, with prolonged use or under certain working conditions (such as vibration, temperature changes, external forces, etc.), these fasteners are prone to loosening, leading to pipe fixation failure and potentially causing leaks, malfunctions, and other problems. Therefore, it is necessary to develop a secondary tightening knob to prevent pipe clamp loosening.

[0003] The primary purpose of the secondary tightening knob for preventing pipe clamp loosening is to prevent the pipe clamp from loosening due to vibration, pressure changes, or long-term use, thereby ensuring the stability and safety of the equipment. In existing technologies, traditional secondary tightening knobs for preventing pipe clamp loosening lack a stable clamping function, and the pipe clamp may gradually loosen. This loosening will lead to a decrease in the clamping force at the pipe connection, which in turn will affect the stability and sealing of the pipeline. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a secondary tightening knob for preventing pipe clamp loosening, which aims to improve the problem that loose pipe clamps may lead to a decrease in clamping force at pipe connections, thereby affecting the stability and sealing of the pipes.

[0006] Preferably, the fixing component includes a fixing shaft, the lower surface of which is fixedly connected to the upper surface of the first clamping frame, and a sleeve is fixedly connected to the inner wall of the fixing shaft.

[0007] Preferably, a fixing plate is fixedly connected to the upper surface of the fixing shaft, and a rotating shaft is rotatably connected inside the fixing plate.

[0008] Preferably, a handle is fixedly connected to the outer wall of the rotating shaft, and a pressure block is fixedly connected to the outer wall of the rotating shaft.

[0010] Preferably, the outer wall of the pressure block is rotatably connected to the inside of the fixed shaft, and the outer wall of the pressure block is attached to the outer wall of the pressing groove.

[0011] Preferably, the lower surface of the traction shaft is attached to the upper surface of the second clamping frame.

[0012] Preferably, rubber pads are fixedly connected to the outer walls of both the first clamping frame and the second clamping frame.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the rotating handwheel drives the threaded shaft to rotate, and the cooperation between the rotating shaft, rotating plate, sliding shaft and sliding frame drives the first clamping frame and the second clamping frame to clamp and stabilize the pipe, thereby enhancing the fixation and stability of the pipe and preventing the pipe from loosening or shifting due to external forces.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a secondary tightening knob for preventing loosening of pipe clamps, including a handwheel 1. A threaded shaft 2 is fixedly connected inside the handwheel 1. A support frame 3 is rotatably connected to the outer wall of the threaded shaft 2. A rotating shaft 4 is fixedly connected inside the support frame 3. A rotating plate 6 is rotatably connected to the outer wall of the rotating shaft 4. A sliding groove 7 is provided inside the rotating plate 6. A sliding frame 5 is threadedly connected to the outer wall of the threaded shaft 2. A sliding shaft 8 is fixedly connected inside the sliding frame 5. The outer wall of the sliding shaft 8 is slidably connected to the inner wall of the sliding groove 7. A first clamping frame 11 and a second clamping frame 19 are fixedly connected to the outer wall of the rotating plate 6. A fixing component is provided on the upper surface of the first clamping frame 11. The fixing component is used to fix the position between the pipe clamp and the pipe.

[0025] Specifically, rotating the handwheel 1 drives the threaded shaft 2 to rotate, while the support frame 3 supports the position of the threaded shaft 2 during rotation. The rotation of the threaded shaft 2 drives the threaded sliding frame 5 to move, and the movement of the sliding frame 5 causes the sliding shaft 8 to slide on the inner wall of the sliding groove 7. Thus, the sliding of the sliding shaft 8 on the inner wall of the sliding groove 7 causes the movement of the sliding frame 5 to drive the rotating plate 6 to rotate. At the same time, the rotating shaft 4 supports the position of the rotating plate 6 during rotation, and the support frame 3 fixes the position of the rotating shaft 4. The rotation of the rotating plate 6 causes the first clamping frame 11 and the second clamping frame 19 to clamp the pipe together, thereby enhancing the stability of the pipe and preventing the pipe from loosening or shifting due to vibration, temperature changes, or other factors.

[0026] Reference Figure 1The fixing component includes a fixing shaft 10, the lower surface of the fixing shaft 10 is fixedly connected to the upper surface of the first clamping frame 11, and a sleeve 9 is fixedly connected to the inner wall of the fixing shaft 10.

[0027] Specifically, the first clamping frame 11 fixes the position of the fixed shaft 10, and the fixed shaft 10 fixes the position of the sleeve 9.

[0028] Reference Figures 3-5 A fixed plate 17 is fixedly connected to the upper surface of the fixed shaft 10. A rotating shaft 16 is rotatably connected inside the fixed plate 17. A handle 14 is fixedly connected to the outer wall of the rotating shaft 16. A pressure block 15 is fixedly connected to the outer wall of the rotating shaft 16. A traction shaft 13 is slidably connected inside the sleeve 9. The outer wall of the traction shaft 13 is slidably connected to the inside of the fixed shaft 10. A pressing groove 18 is opened on the upper surface of the traction shaft 13. The outer wall of the pressure block 15 is rotatably connected to the inside of the fixed shaft 10. The outer wall of the pressure block 15 is attached to the outer wall of the pressing groove 18. The lower surface of the traction shaft 13 is attached to the upper surface of the second clamping frame 19. Rubber pads 12 are fixedly connected to the outer walls of both the first clamping frame 11 and the second clamping frame 19.

[0029] Specifically, the fixed shaft 10 fixes the fixed plate 17 in place, and the fixed plate 17 supports the rotation of the rotating shaft 16. Simultaneously, the pressing handle 14 drives the rotating shaft 16 to rotate, which in turn drives the pressure block 15 to rotate inside the fixed shaft 10. The rotation of the pressure block 15 then presses and stabilizes the traction shaft 13 and the second clamping frame 19 through the pressing groove 18, thus securing the second clamping frame 19 to the pipe. This achieves the function of tightening the pipe clamp and fixing the pipe. Meanwhile, the rubber pad 12, with its excellent elasticity, can completely conform to the pipe surface, forming a tight and seamless connection, effectively preventing water and air leaks. The rubber pad 12 also increases the friction between the pipe and the pipe clamp, providing an anti-slip effect and ensuring that the pipe is not easily loosened or displaced under external force.

[0030] Working principle: In use, the first clamping frame 11 is rotated to drive the threaded shaft 2 to rotate under the support of the support frame 3. The rotation of the threaded shaft 2 drives the sliding frame 5 to move. The movement of the sliding frame 5 drives the sliding shaft 8 to slide on the inner wall of the sliding groove 7. Thus, the sliding shaft 8 slides on the inner wall of the sliding groove 7, which serves to drive the rotating plate 6. At the same time, the rotating shaft 4 supports the rotating plate 6 to rotate. The rotation of the rotating plate 6 drives the first clamping frame 11 to clamp the pipe position. This fixing effect can not only prevent the pipe from generating noise, damage or affecting the normal operation of the equipment due to shaking or vibration, but also resist the thrust generated by the fluid in the pipe, avoiding pipe deformation or rupture.

[0031] When the first clamping frame 11 and the second clamping frame 19 clamp the pipe, pressing the handle 14 drives the rotating shaft 16 to rotate under the support of the fixed plate 17. The rotation of the rotating shaft 16 drives the pressure block 15 to rotate inside the fixed shaft 10. Thus, the rotation of the fixed shaft 10 presses against the upper surface of the pressing groove 18, thereby pressing the position of the traction shaft 13. Pressing the traction shaft 13 presses the position between the first clamping frame 11 and the pipe. Pressing and fixing the position of the second clamping frame 19 achieves the first clamping. The secure connection between the support 11 and the second clamping frame 19 further tightens the pipe, not only increasing the friction between the pipe and the support to prevent the pipe from slipping during operation, but also ensuring that the pipe clamp can firmly fix the pipe through the tightening action of the traction shaft 13, preventing the pipe from loosening or shifting due to external forces. At the same time, the secondary tightening knob of the pipe clamp uses a rubber pad 12 when clamping the pipe, which not only enhances the sealing performance, but also plays a role in shock absorption, anti-slip, compensating for pipe errors, and improving weather resistance and corrosion resistance.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
