The utility model has a simple structure, a reasonable design, high overall stability, good impact resistance, and is stable and reliable during use. At the same time, a positioning platform with sealing capability is provided, which effectively guarantees the reliability of the connection with the external pipe without increasing the size too much;

[0004] Although the high-strength U-shaped pipe fittings mentioned above have good impact resistance when in use, they are inconvenient to support and prevent deformation of the pipe fittings during use, resulting in low applicability during use. Utility Model Content

[0005] The purpose of the utility model is to provide a high-strength flame-retardant pipe fitting to solve the defect that the existing high-strength flame-retardant pipe fittings are inconvenient to support.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a high-strength flame-retardant pipe fitting, comprising a pipe fitting body and a connecting pipe;

[0007] A protective structure is provided on the outside of the pipe body, connecting pipes are fixed at both ends of the pipe body, and a sealing structure is provided on the outside of one end of the connecting pipe;

[0009] A supporting structure is provided on the outside of the protective structure, and the supporting structure includes a bracket, a clamp, a mounting hole, a fixing nut, a rubber seat and a rubber sleeve. The rubber seat is provided on the outside of the protective structure, and the bottom end of the rubber seat is fixed with a bracket. Mounting holes are evenly penetrated on both sides of the bottom of the bracket, and a clamp is penetrated at the top of the bracket. The outer sides of the clamp at the bottom end of the bracket are threadedly connected to the fixing nut, and the top of the clamp is fixed with a rubber sleeve.

[0010] When using the device, by providing a supporting structure, the device is able to prevent deformation, thereby improving the applicability of the high-strength flame-retardant pipe fitting during use; by providing a protective structure, the device is able to flame retard, thereby improving the stability of the high-strength flame-retardant pipe fitting during use; by providing a sealing structure, the device is able to seal, thereby improving the sealing performance of the high-strength flame-retardant pipe fitting during use; by providing a pressure-resistant structure, the device is able to strengthen, thereby extending the service life of the high-strength flame-retardant pipe fitting during use.

[0011] Preferably, the protective structure includes a protective layer, a stainless steel layer, and a flame-retardant layer. The flame-retardant layer is fixed to the outer wall of the pipe body. The outer wall of the flame-retardant layer is bonded to the stainless steel layer, and the outer wall of the stainless steel layer is bonded to the protective layer. The flame-retardant layer is provided on the outer side of the pipe body. The flame-retardant layer is actually a mineral fiber layer. It has excellent thermal insulation properties, can effectively prevent the conduction and loss of heat, has good fireproof and flame-retardant properties, and can prevent the spread of flames and the generation of smoke.

[0012] Preferably, the protective layer is actually a fluorocarbon coating, and the flame-retardant layer is actually a mineral fiber layer. One side of the protective layer contacts the top of the rubber seat, and the other side of the protective layer contacts the bottom of the rubber sleeve.

The protective layer is actually a fluorocarbon coating, which has excellent chemical resistance, high temperature resistance, and weather resistance, and can protect the surface of the stainless steel layer from erosion by acids, alkalis, salts, and solvents.

[0013] Preferably, the clamp and the bracket are fixedly connected by a fixing nut, and the clamp and the bracket form a sliding structure. The pipe body is moved to the top of the rubber seat, and the clamp is sleeved on the outside of the pipe body, so that the bottom end of the clamp passes through the interior of the bracket. The clamp drives the rubber sleeve to contact the outside of the protective layer. Under the action of the fixing nut, the pipe body is fixed to the top of the rubber seat. Under the action of the rubber seat and the rubber sleeve, wear between the pipe body, the clamp and the bracket is avoided. Under the action of the mounting hole, the bracket is conveniently fixed to the ground or wall, thereby facilitating the support of the pipe body and preventing deformation of the pipe body.

The adhesive layer is bonded to the inner sidewall of the pipe body, the reinforcement layer is bonded to the inner sidewall of the adhesive layer, and the anti-corrosion layer is bonded to the inner sidewall of the reinforcement layer. By making the reinforcement layer an aluminum alloy layer, the strength and rigidity of the pipe body can be effectively improved, making the pipe body more resistant to deformation and rupture when subjected to external forces.

[0017] Preferably, the reinforcing layer is actually an aluminum alloy layer, and the anti-corrosion layer is actually a fiberglass lining layer. Since the anti-corrosion layer is actually a fiberglass lining layer, it has the functions of preventing corrosion and leakage, protecting the internal structure of the pipe body, and improving the pressure resistance. At the same time, it can effectively prevent the medium from eroding the inner wall of the pipe body, ensuring the long-term stable operation of the pipe body.

Under the action of the mounting hole, it is convenient to fix the bracket to the ground or wall, thereby facilitating the support of the pipe body and preventing the pipe body from being deformed. The function of the device to prevent deformation is realized, thereby improving the applicability of the high-strength flame-retardant pipe during use.

[0020] By providing a protective structure, a flame retardant layer is provided on the outside of the pipe body. The flame retardant layer is actually a mineral fiber layer, which has excellent thermal insulation performance, can effectively prevent the conduction and loss of heat, has good fire resistance and flame retardant performance, can prevent the spread of flames and the generation of smoke, and under the action of the stainless steel layer, protects the surface of the pipe body from corrosion and oxidation. The protective layer is actually a fluorocarbon coating, which has excellent chemical resistance, high temperature resistance and weather resistance, and can protect the surface of the stainless steel layer from erosion by acids, alkalis, salts and solvents, thereby realizing the flame retardant function of the device, thereby improving the stability of the high-strength flame retardant pipe during use;

[0021] By providing a sealing structure, the sealing ring is put on the outside of the connecting pipe, and the sealing ring drives the rubber strip to move into the inside of the placement groove, thereby fixing the sealing ring and the connecting pipe to each other. When the pipe body is connected to other pipes through the connecting pipe, the sealing ring enhances the sealing performance of the connection, realizes the function of facilitating sealing of the device, and thus improves the sealing performance of the high-strength flame-retardant pipe fitting when in use;

[0022] By providing a pressure-resistant structure and the reinforcement layer being actually an aluminum alloy layer, the strength and rigidity of the pipe body can be effectively improved, and the pipe body can be better resistant to deformation and cracking when subjected to external forces. The anti-corrosion layer is actually a fiberglass lining layer, which has the functions of anti-corrosion, anti-leakage, protection of the internal structure of the pipe body and improved pressure resistance.
