A fixing bolt is installed at one end of the docking rod, and a limiting rotating plate is installed on the outer side of the fixing bolt. The positioning rod and the docking groove allow the positioning rod to be inserted into the corresponding docking rod. The fixing bolt can position the connection between the positioning rod and the connecting rod. The limiting rotating plate can rotate relative to the positioning shaft, thereby positioning the fixing bolt and preventing the fixing bolt from loosening during use.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation: due to the material properties of silicone tubes, they are prone to deformation during use, which can easily affect the flow of fluids inside. Utility Model Content

[0005] The purpose of this utility model is to provide a high-strength silicone tube with stable connection, so as to solve the problem in the background art that silicone tubes are prone to deformation during use due to their material properties, which can easily affect the internal fluid flow.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-strength silicone tube with stable connection, comprising a silicone tube body, wherein a quick-connect assembly is installed at the connection of the silicone tube body, and the quick-connect assembly is installed at the ends of the two silicone tube bodies.

[0007] The silicone tube body includes an inner tube, a middle tube, and a protective layer, and the inner tube, middle tube, and protective layer are distributed from the inside out, and the reinforcing structures are located between the inner tube and the middle tube and between the middle tube and the protective layer, respectively.

[0008] The silicone tube body is designed with a multi-layer structure, and the silicone tube body has a reinforcing structure inside to enhance its strength.

[0009] Preferably, the reinforcing structure includes a reinforcing layer installed between the inner tube and the middle tube, and a supporting layer is fixedly connected between the middle tube and the protective layer. The reinforcing layer is made of nylon with a mesh structure, and the supporting layer is made of metal and is distributed in a spiral shape between the middle tube and the protective layer.

[0010] Preferably, the quick-connect assembly includes a connecting ring and a fixing ring installed at the ends of two silicone tube bodies, and a sliding sleeve is slidably connected to the outside of the connecting ring. The sliding sleeve has an internal thread, and the fixing ring has an external thread. The connecting ring and the fixing ring are engaged with each other, and the sliding sleeve is installed on the outside of the fixing ring through the internal thread and the external thread on the outside of the fixing ring.

[0011] Preferably, a sealing ring is fixedly connected to the side of the connecting ring near the fixed ring, and both the bottom of the sealing ring and the bottom of the connecting ring are provided with sealing rings.

[0012] Preferably, the fixing ring has an installation groove inside on the side near the connecting ring, and both the bottom of the installation groove and the top of the fixing ring have sealing grooves.

[0013] Preferably, the mounting groove and the sealing ring are engaged with each other, and the sealing ring is engaged with the inside of the sealing groove.

[0014] Preferably, the silicone tube body has a bending tube at the bend, and both ends of the bending tube are fixedly connected to buffer tubes, and the bending tube is connected to the silicone tube body through the buffer tubes.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This type of high-strength silicone tube with stable connection, during the flow inside the inner tube, the reinforcing layer will reinforce the outside of the inner tube, improving the tensile strength and pressure resistance of the inner tube. The support layer supports the outside of the middle tube and the inside of the protective layer, thereby improving the overall strength of the silicone tube body. At the same time, the support layer is distributed in a spiral shape on the outside of the middle tube to form a spring-like structure. When the silicone tube body deforms, the support layer can assist the silicone tube body to return to its original shape, reducing twisting and deformation during use.

[0017] Furthermore, since the buffer tube is designed as a corrugated pipe structure, it can absorb and buffer the instantaneous pressure fluctuations caused by the water hammer effect, thereby reducing the impact force of the pressure wave on the silicone tube body. In addition, the buffer tube can expand, contract and bend, which can compensate for the displacement of the silicone tube body caused by the water hammer effect. When there is a sudden pressure change in the pipeline, it can reduce the stress concentration of the silicone tube body and reduce the risk of its rupture or leakage. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1 - Figure 6 The present invention provides the following technical solution: a high-strength silicone tube with stable connection, comprising a silicone tube body 1, a quick-connect component 2 installed at the connection of the silicone tube body 1, and the quick-connect component 2 installed at the ends of the two silicone tube bodies 1; the silicone tube body 1 comprises an inner tube 14, a middle tube 16 and a protective layer 18, and the inner tube 14, the middle tube 16 and the protective layer 18 are distributed in a structure from the inside out, and the reinforcing structure is located between the inner tube 14 and the middle tube 16 and between the middle tube 16 and the protective layer 18 respectively; the silicone tube body 1 is provided with a multi-layer structure, and the silicone tube body 1 is provided with a reinforcing structure to enhance its strength; the reinforcing structure includes a reinforcing layer 15 installed between the inner tube 14 and the middle tube 16, and a supporting layer 17 is fixedly connected between the middle tube 16 and the protective layer 18, the reinforcing layer 15 is made of nylon material with a mesh structure, and the supporting layer 17 is made of metal material and is spirally distributed between the middle tube 16 and the protective layer 18.

[0027] During pipeline use, the liquid will flow inside the silicone tube body 1. At this time, the liquid will flow inside the inner tube 14 that constitutes the silicone tube body 1. During the flow of the liquid inside the inner tube 14, the reinforcing layer 15 will reinforce the outside of the inner tube 14, improve the tensile strength and pressure resistance of the inner tube 14, making it less prone to damage under high pressure or mechanical impact, while maintaining the flexibility of the silicone tube. The middle tube 16 is located outside the reinforcing layer 15, and the middle tube 16 completely wraps the inner tube 14 and the reinforcing layer 15, thereby improving the thermal insulation performance inside the inner tube 14.

[0028] During the use of the silicone tube body 1, the support layer 17 is located outside the middle tube 16 to protect the inner tube 14 and the middle tube 16. The support layer 17 is made of metal and is spirally distributed outside the middle tube 16. The support layer 17 supports the outside of the middle tube 16 and the inside of the protective layer 18, thereby improving the overall strength of the silicone tube body 1. At the same time, the spiral distribution of the support layer 17 outside the middle tube 16 forms a spring-like structure. When the silicone tube body 1 deforms, the support layer 17 can help the silicone tube body 1 to return to its original shape, reducing twisting and deformation during use.

[0029] Example 2: Based on Example 1, a quick-connect assembly is also disclosed, the specific structure of which is as follows: The quick-connect assembly 2 includes a connecting ring 3 and a fixing ring 4 installed at the ends of two silicone tube bodies 1. A sliding sleeve 9 is slidably connected to the outside of the connecting ring 3. The sliding sleeve 9 has an internal thread 10, and the fixing ring 4 has an external thread 11. The connecting ring 3 and the fixing ring 4 are interlocked. The sliding sleeve 9 is installed on the outside of the fixing ring 4 through the internal thread 10 and the external thread 11 on the outside of the fixing ring 4. The side of the connecting ring 3 closest to the fixing ring 4 is fixedly connected... A sealing ring 5 is provided, and sealing rings 6 are provided at the bottom of the sealing ring 5 and the bottom of the connecting ring 3; a mounting groove 7 is provided inside the fixed ring 4 on the side near the connecting ring 3, and sealing grooves 8 are provided at the bottom of the mounting groove 7 and the top of the fixed ring 4; the mounting groove 7 is engaged with the sealing ring 5, and the sealing ring 6 is engaged with the sealing groove 8; a bent tube 12 is provided at the bend of the silicone tube body 1, and buffer tubes 13 are fixedly connected to both ends of the bent tube 12, and the bent tube 12 is connected to the silicone tube body 1 through the buffer tubes 13.

[0030] When the silicone tube bodies 1 need to be connected, the connecting ring 3 and the fixing ring 4 are aligned and installed. The sealing ring 5 is installed inside the mounting groove 7, and the sealing rings 5 ​​at the bottom of the connecting ring 3 and the bottom of the sealing ring 5 are connected to the sealing grooves 8 at the bottom of the mounting groove 7 and the top of the fixing ring 4. The connecting ring 3 and the fixing ring 4 form a sealing structure through the connection of the sealing ring 5 and the mounting groove 7, and the sealing performance is improved through the connection between the sealing ring 6 and the sealing groove 8. After the connecting ring 3 and the fixing ring 4 are installed, the sliding sleeve 9 is rotated. The internal thread 10 on the inner side of the sliding sleeve 9 is connected to the external thread 11 on the outer side of the fixing ring 4, thereby fixing the sliding sleeve 9 to the outside of the fixing ring 4. At the same time, the sliding sleeve 9 will drive the connecting ring 3 and the fixing ring 4 to fit together, completing the installation of the silicone tube body 1. The silicone tube body 1 can be disassembled by separating the sliding sleeve 9 and the fixing ring 4.

[0031] During the flow of liquid inside the silicone tube body 1, a sudden flow or cessation of liquid flow will cause a water hammer effect. At this time, buffer tubes 13 are set at both ends of the bent tube 12. Since the buffer tube 13 is designed as a corrugated tube, it can absorb and buffer the instantaneous pressure fluctuations caused by the water hammer effect, thereby reducing the impact force of the pressure wave on the silicone tube body 1. In addition, the buffer tube 13 can expand, contract and bend, which can compensate for the displacement of the silicone tube body 1 caused by the water hammer effect. When a sudden pressure change occurs in the pipeline, it can reduce the stress concentration of the silicone tube body 1 and reduce the risk of its rupture or leakage.
