Description

Technical Field

[0001] The utility model relates to the technical field of plumbing pipes, and specifically relates to a clamping structure for building plumbing pipes. Background Art

[0002] Plumbing pipes refer to pipe systems used for transporting fluids such as hot water, cold water, and heating. They are widely used in the fields of construction, industry, and municipal administration. According to their uses and characteristics, plumbing pipes can be divided into water supply pipes, drainage pipes, hot water pipes, heating pipes, etc. Plumbing pipes usually include copper pipes, steel pipes, and hoses. A hose is a flexible pipe, usually made of rubber, PVC, or other flexible materials. Hoses have good flexibility and stretchability, and can adapt to different installation environments and requirements. The existing clamping method for water pipes is to align the end faces of two pipes, then put on a clamp, and tightly fix the two halves of the clamp together with bolts or screws. During the tightening process, the sealing gasket inside the clamp will be compressed, thereby filling the tiny gaps between the pipes to achieve sealing.

[0003] However, the existing technical solutions still have the following problems:

[0004] Clamp connections usually rely on applying external force to the pipes to form a seal. However, due to the elasticity of the hose, it may be difficult for the clamp to form a stable seal on the hose. Due to the elasticity of the hose, the clamp may not be able to fully compress the hose, resulting in a risk of leakage at the connection. Incomplete sealing may also cause pressure loss when the fluid passes through the connection, affecting the efficiency of the system. Summary of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a clamping structure for building plumbing pipes to at least solve one of the problems raised in the background art, such as: since the hose is flexible, it is prone to deformation during installation and use. Through the combined use of a clamping ring, an outer clamping sleeve, and a sealing sleeve, this deformation of the hose can be adapted, while maintaining the stability and tightness of the connection.

[0006] To achieve the above object, the utility model provides the following technical solution: A clamping structure for building plumbing pipes, including a clamp composed of two arc-shaped plates. An inner clamping ring is arranged inside the clamp. An outer clamping sleeve is sleeved outside the inner clamping ring, and a sealing sleeve is sleeved outside the outer clamping sleeve. All components can be detachably arranged.

[0007] Further, a threaded coil is arranged on the outside of the inner clamping ring. The inner wall of the outer clamping sleeve is fixedly connected with an inner thread line matching it, and the inner diameter of the outer clamping sleeve is larger than the outer diameter of the inner clamping ring.

[0008] Further, one end inner wall of the outer clamping sleeve is arranged in a conical shape. The narrow end of the cone is close to the mouth of the outer clamping sleeve, and the wide end of the cone is close to the inner thread line.

[0009] Furthermore, the length of the sealing sleeve is more than twice the length of the outer ferrule.

[0010] Furthermore, the inner wall of the sealing sleeve is attached to the outer side of the outer ferrule, and the outer side of the sealing sleeve is attached to the inner sides of the two arc-shaped plates of the clamp.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, an inner snap ring is inserted into a hose, then an outer ferrule is used on the outside to clamp the hose between the inner snap ring and the outer ferrule, and the two inner snap rings are sealed by a sealing sleeve. Finally, a clamp is used for fixation. The use of the outer ferrule ensures a tight fit between the hose and the snap ring, effectively preventing fluid leakage at the connection. The combined design of the snap ring, outer ferrule, sealing sleeve and clamp makes the installation and adjustment more flexible and has strong adaptability. Due to its flexibility, the hose is prone to deformation during installation and use. Through the combined use of the snap ring, outer ferrule and sealing sleeve, this deformation of the hose can be adapted while maintaining the stability and sealing performance of the connection.

[0018] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0019] As Figures 1 to 4 shown, a clamping structure for building water heating pipes includes a clamp 1 composed of two arc-shaped plates. An inner snap ring 2 is arranged inside the clamp 1. An outer ferrule 3 is sleeved on the outside of the inner snap ring 2. A sealing sleeve 4 is sleeved on the outside of the outer ferrule 3. All components can be detachably arranged.

[0020] As Figures 1 to 4As shown, when a clamping structure for building water heating pipes in the present utility model is in use, the clamp 1 is composed of two arc-shaped plates, and these two arc-shaped plates can form a complete ring around the water heating pipe. The clamp 1 is responsible for providing the main fastening force to ensure the stability and tightness of the connection of the water heating pipe. The inner clamping ring 2 is located inside the clamp 1 and is in direct contact with the water heating pipe. It ensures that it can be tightly inserted into the hose, providing support and positioning for the outer clamping sleeve 3. The outer clamping sleeve 3 is sleeved on the outside of the inner clamping ring 2, and together with the inner clamping ring 2, it forms a complete clamping structure to fix the hose between the inner clamping ring 2 and the outer clamping sleeve 3, so that the position where the end of the hose is not easily clamped is replaced by the inner clamping ring 2. When using the sealing sleeve 4 to enclose the two inner clamping rings 2, the clamp 1 provides the fastening force to achieve the effect of fixing the two hoses. Moreover, all components can be separately arranged, and the clamp 1, the inner clamping ring 2, the outer clamping sleeve 3, and the sealing sleeve 4 can be separately replaced or adjusted, increasing the flexibility and maintainability of the structure.

[0021] As Figures 1 to 4 shown, a thread coil 5 is arranged on the outer side of the inner clamping ring 2, and an inner thread 6 matching it is fixedly connected to the inner wall of the outer clamping sleeve 3, and the inner diameter of the outer clamping sleeve 3 is larger than the outer diameter of the inner clamping ring 2.

[0022] Specifically, after the inner clamping ring 2 is inserted into the hose through this setting, the hose is located between the outer side of the thread coil 5 and the inner wall of the outer clamping sleeve 3. The thread coil 5 and the inner thread 6 squeeze the hose so that it is fixed between the inner clamping ring 2 and the outer clamping sleeve 3. The inner clamping ring 2 replaces the hose port and is fixed by the clamp 1 and the sealing sleeve 4.

[0023] As Figure 4 shown, one end inner wall of the outer clamping sleeve 3 is conical, with the narrow end of the cone close to the mouth of the outer clamping sleeve 3 and the wide end of the cone close to the inner thread 6.

[0024] Specifically, through this setting, the hose can be gradually squeezed between the inner clamping ring 2 and the outer clamping sleeve 3, preventing the inner wall of the outer clamping sleeve 3 from squeezing the hose out from the outside of the inner clamping ring 2, and making the hose gradually tightened.

[0025] As Figure 2 shown, the length of the sealing sleeve 4 is more than twice the length of the outer clamping sleeve 3.

[0026] Specifically, through this setting, the sealing sleeve 4 can seal the ports between the two outer clamping sleeves 3 and the inner clamping rings 2 inside the outer clamping sleeves 3, used to fill the gaps between the inner clamping rings 2, ensure tightness, prevent water or other fluids from leaking at the connection, and ensure the stable operation of the system.

[0027] As Figure 1 shown, the inner wall of the sealing sleeve 4 is in fitting connection with the outer side of the outer clamping sleeve 3, and the outer side of the sealing sleeve 4 is in fitting connection with the inner sides of the two arc-shaped plates of the clamp 1.

[0028] Specifically, through this setting, the outer side of the sealing sleeve 4 is attached to and connected with the inner sides of the two arc-shaped plates of the clamp 1, ensuring that when the clamp 1 is tightened, the sealing sleeve 4 can receive uniform compressive force, thereby enhancing the sealing effect. Through the multi-layer structure of the inner clamping ring 2, the outer clamping sleeve 3 and the sealing sleeve 4, multiple sealing lines of defense are formed, improving the sealing performance of the connection.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
