[0021] 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.

[0022] Reference Figures 1-3 One embodiment of this utility model is a sealing structure for connecting sewage pipes, including a pipe 1 and a pipe 2. The outer walls of the pipe 1 and the pipe 2 are fitted with internal fasteners. The outer walls of the internal fasteners are provided with sealing sleeves 3. The length of the sealing sleeves 3 is greater than the length of the internal fasteners. The outer walls of the sealing sleeves 3 are provided with external fasteners. The length of the external fasteners is greater than the length of the sealing sleeves 3. Specifically, the rolled sealing sleeve 3 is placed on pipe 1 or pipe 2. Then, the left fixing member 4 is placed on the ground. Multiple sealing strips 3 are placed in the groove rings 9 of pipe 1 and pipe 2. Then, pipe 1 and pipe 2 are placed on the left fixing member 4. After placement, the right fixing member 5 is fixed to the left fixing member 4. Then, the sealing sleeve 3 is moved to the middle position of the left fixing member 4 and the right fixing member 5. The rolled sealing sleeve 3 is rolled up from the middle to both sides until it completely surrounds the left fixing member 4 and the right fixing member 5. Then, it is fixed again with external fixing components to ensure the sealing of the pipe connection. Through double sealing to prevent leakage, it can effectively block sewage penetration. The EPDM rubber sealing sleeve has excellent elasticity and weather resistance, can adapt to temperature changes and sewage corrosion, and its length covers the internal fixing member to avoid sealing blind spots and ensure long-term sealing effect. It improves the obvious deficiencies of existing sewage pipe connection technology in terms of sealing performance, fixing stability, durability and adaptability.

[0023] Reference Figures 1-2 , Figure 4 The internal fasteners include a left fastener 4 and a right fastener 5, which are symmetrical. The left fastener 4 has a uniformly distributed fastening groove 6, and the right fastener 5 has a fastening post 7. The fastening post 7 is installed in the fastening groove 6 of the left fastener 4. The inner walls of the left fastener 4 and the right fastener 5 are installed on the outer walls of pipe 1 and pipe 2. The first groove ring 9 is uniformly distributed on one side of pipe 1 and pipe 2. The second groove ring 10 is uniformly distributed on the inner walls of the left fastener 4 and the right fastener 5. An O-shaped groove is formed between the first groove ring 9 and the second groove ring 10. A sealing strip 11 is provided between pipe 1 and pipe 2 and the left fastener 4 and the right fastener 5. The sealing strip 11 is located in the O-shaped groove.

[0024] Specifically, the internal positioning is achieved through the cooperation of the fixing grooves 6 and fixing posts 7 of the left and right fixing parts. The external part uses ductile iron semi-ring parts fastened with bolts to form a double fixing structure, which can resist external impact and pipe deformation and prevent loosening of the connection. The cast iron material has high strength and good toughness, and the inner wall coating can prevent corrosion, extend service life, and reduce the risk of cracking. The sealing strip 11 fills the gap of the O-ring groove. With the elastic deformation of the sealing strip itself, it tightly fits the inner wall of the groove ring 9 and the groove ring 10, thereby forming the first sealing barrier on the inner side of the pipe connection, blocking the path of sewage seeping from the pipe interface to the outside.

[0025] Reference Figures 3-4 The external fasteners include a left outer component 12 and a right outer component 13. The left outer component 12 and the right outer component 13 are semi-circular structures. Side plates 14 are provided at the bottom of the left outer component 12 and the top of the right outer component 13. Bolts 15 are evenly installed inside one of the side plates 14. The outer wall of the bolts 15 is threaded to the inside of the other side plate 14. The inner walls of the left outer component 12 and the right outer component 13 are coated with epoxy resin.

[0026] Specifically, an O-ring is formed by combining the grooved rings 9 and 10 on pipe 1, pipe 2, and the internal fixing components. A sealing strip 11 is embedded in the O-ring to create a sealed space. The connection area is fully covered by an EPDM rubber sealing sleeve, providing double protection to effectively prevent sewage penetration. The EPDM rubber sealing sleeve has excellent elasticity and weather resistance, adapting to temperature changes and sewage corrosion. Its length covers the internal fixing components, avoiding sealing blind spots and ensuring long-term sealing performance.

[0027] Reference Figure 2 The sealing sleeve 3 is a EPDM rubber sealing sleeve.

[0028] Specifically, the sealing sleeve 3 is made of EPDM rubber. The elasticity of EPDM rubber can adapt to slight deformation during pipeline operation, ensuring long-term stability of the sealing state.

[0029] Working principle: First, the rolled sealing sleeve is placed on pipe 1 or pipe 2. Then, the left fixing component 4 is placed on the ground. Multiple sealing strips 3 are placed inside the groove rings 9 of pipe 1 and pipe 2. Then, pipe 1 and pipe 2 are placed on the left fixing component 4. After placement, the right fixing component 5 is fixed to the left fixing component 4. Then, the sealing sleeve 3 is moved to the middle position of the left fixing component 4 and the right fixing component 5. The rolled sealing sleeve 3 is rolled up from the middle to both sides until it completely surrounds the left fixing component 4 and the right fixing component 5. Then, it is fixed again with the external fixing component to ensure the sealing of the pipe connection. The groove rings 9 and 10 on pipe 1, pipe 2 and the internal fixing component are combined to form an O-groove. The sealing strip 11 is embedded in the O-groove to form a sealing space. The connection part is fully covered by the EPDM rubber sealing sleeve. The double protection can effectively prevent sewage penetration. EPDM rubber sealing sleeves possess excellent elasticity and weather resistance, adapting to temperature changes and sewage corrosion. Their length covers the internal fasteners, avoiding sealing blind spots and ensuring long-term sealing performance. Internally, initial positioning is achieved through the interlocking grooves of the left and right fasteners. Externally, ductile iron semi-rings are bolted in, forming a double-fixing structure that resists external impacts and pipe deformation, preventing loosening. The high strength and toughness of the cast iron material, along with the inner coating to prevent corrosion and extend service life, and the external fixing groove 16 to ensure component alignment, reducing the risk of cracking.
