[0017] two first connecting plates, which are both arranged on the first half ring;

[0031] Optionally, the first and second semi-rings are covered with an insulating sleeve.

[0032] By adopting the above technical solution, an insulation sleeve is wrapped around the first and second half-rings, thereby stabilizing the temperature of the water pipes inside the first and second half-rings, reducing the extent of thermal expansion and contraction of the water pipes, and improving the adaptability of the first and second half-rings to water pipes at different temperatures.

[0034] 1. By horizontally installing a connecting spring plate on the retaining ring and installing a rubber sealing strip on the connecting spring plate, when the two retaining rings are clamped onto the water pipe using the connecting mechanism, the connecting spring plate is pressed against the water pipe by the buffer mechanism. The rubber sealing strip provides an elastic seal at the connection between the connecting spring plate and the water pipe. The buffer mechanism buffers the displacement of the connecting spring plate caused by the thermal expansion and contraction of the water pipe. This ensures the fixing and sealing effect of the retaining ring on the water pipe, while also reducing the probability of the retaining ring being damaged due to the thermal expansion and contraction or vibration of the pipe, thus protecting the pipe.

[0035] 2. By installing a buffer spring and a hydraulic damper on the retaining ring, the buffer spring and the hydraulic damper work together to buffer the displacement of the connecting spring plate after being subjected to force, so that the connecting spring plate can adapt to the deformation of the water pipe after thermal expansion and contraction.

[0036] 3. By creating anti-slip textures on the side wall where the connecting spring plate contacts the water pipe, the friction between the connecting spring plate and the water pipe is increased, thereby improving the connection strength between the first and second half-rings and the water pipe.

[0040] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2 This application will be described in further detail.

[0041] This application discloses a splicing water pipe clamp.

[0042] Reference Figure 1The splicing water pipe clamp includes two clamping rings 11 and a connecting mechanism 2. The two clamping rings 11 cooperate with each other under the action of the connecting mechanism 2 to clamp the water pipe. The clamping rings 11 are provided with elastic sealing devices 3, and the clamping rings 11 make contact and seal with the water pipe through the elastic sealing devices 3.

[0043] Reference Figure 1 and Figure 2 The elastic sealing device 3 includes a connecting spring plate 31, a rubber sealing strip 32, and a buffer mechanism 33. The connecting spring plate 31 is slidably mounted on the inner wall of the retaining ring 11 along the radial direction. Several anti-slip grooves are evenly distributed on the side wall of the connecting spring plate 31 that contacts the water pipe. The rubber sealing strip 32 is fixedly mounted on the side wall of the connecting spring plate 31 closest to the water pipe and abuts against the water pipe. The buffer mechanism 33 is disposed on the retaining ring 11 and is used to buffer the displacement of the connecting spring plate 31.

[0044] Reference Figure 2 The buffer mechanism 33 includes a buffer spring 34 and a hydraulic damper 35. One end of the buffer spring 34 is fixedly connected to the inner wall of the retaining ring 11, and the other end of the buffer spring 34 is fixedly connected to the side wall of the connecting spring plate 31 away from the water pipe. The hydraulic damper 35 is fixedly installed on the inner wall of the retaining ring 11 and connected to the connecting spring plate 31. The buffer spring 34 and the hydraulic damper 35 work together to buffer the displacement of the connecting spring plate 31 after being subjected to force, so that the connecting spring plate 31 can adapt to the deformation of the water pipe after thermal expansion and contraction.

[0045] Reference Figure 1 and Figure 2 The connecting mechanism 2 includes two first connecting plates 21, a second connecting plate 22, a connecting shaft 23, and a limiting component 24. The two retaining rings 11 are divided into a first half-ring 12 and a second half-ring 13. Both first connecting plates 21 are fixedly mounted on the ends of the first half-ring 12. The connecting shaft 23 is rotatably mounted on the two first connecting plates 21. The second connecting plate 22 is fixedly mounted on the ends of the second half-ring 13. The second connecting plate 22 is snapped between the two first connecting plates 21 and fixedly connected to the connecting shaft 23. The limiting component 24 is disposed on the first half-ring 12 and the second half-ring 13 and is used to limit the relative rotational position of the first half-ring 12 and the second half-ring 13.

[0046] Reference Figure 1 and Figure 2The limiting assembly 24 includes a first limiting plate 25, a second limiting plate 26, a limiting screw 27, and a limiting nut 28. The first limiting plate 25 and the second limiting plate 26 are respectively fixedly installed on the ends of the first half-ring 12 and the second half-ring 13 away from the first connecting plate 21 and the second connecting plate 22. When the first half-ring 12 and the second half-ring 13 engage with the water pipe, the first limiting plate 25 and the second limiting plate 26 abut against each other. Both the first limiting plate 25 and the second limiting plate 26 have horizontally communicating limiting holes. The limiting screw 27 passes through the limiting holes on the first limiting plate 25 and the second limiting plate 26, and its head abuts against the outer wall of the first limiting plate 25. The limiting nut 28 is threaded onto the limiting screw 27 and abuts against the outer wall of the second limiting plate 26.

[0047] Reference Figure 2 The limiting nut 28 engages with the head of the limiting screw 27 to clamp the first limiting plate 25 and the second limiting plate 26. This fixes the positions of the first limiting plate 25 and the second limiting plate 26, thus completing the position fixing work of the first limiting plate 25 and the second limiting plate 26.

[0048] Reference Figure 1 and Figure 2 Both the head of the limiting screw 27 and the limiting nut 28 are fitted with rubber sealing rings 14, and a rubber elastic rope 15 connects the two rubber sealing rings 14. This improves the sealing performance between the limiting screw 27 and the limiting nut 28 and the first limiting plate 25 and the second limiting plate 26 through the rubber sealing rings 14. The rubber elastic rope 15 connects the two rubber sealing rings 14, thereby increasing the connection strength between the limiting screw 27 and the limiting nut 28 and reducing the probability of the limiting screw 27 and the limiting nut 28 loosening during prolonged operation.

[0049] Reference Figure 1 and Figure 2 The first half-ring 12 and the second half-ring 13 are covered with an insulation sleeve 16. This stabilizes the temperature of the water pipe inside the first half-ring 12 and the second half-ring 13, reduces the extent of thermal expansion and contraction of the water pipe, and improves the adaptability of the first half-ring 12 and the second half-ring 13 to water pipes at different temperatures.

[0050] The working principle of this application embodiment is as follows:

[0051] A connecting spring plate 31 is horizontally installed on the retaining ring 11, and a rubber sealing strip 32 is installed on the connecting spring plate 31. When the two retaining rings 11 are clamped to the water pipe using the limiting screw 27 and the limiting nut 28, the connecting spring plate 31 is pressed against the water pipe by the buffer spring 34 and the hydraulic damper 35. The rubber sealing strip 32 provides an elastic seal at the connection between the connecting spring plate 31 and the water pipe. The buffer spring 34 and the hydraulic damper 35 buffer the displacement of the connecting spring plate 31 caused by the thermal expansion and contraction of the water pipe. This ensures the fixing and sealing effect of the retaining ring 11 on the water pipe, and also reduces the probability of the retaining ring 11 being damaged due to the thermal expansion and contraction or vibration of the pipe, thus protecting the pipe.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
