Description

Technical Field

[0001] This utility model relates to a connecting pipe structure. Background Technology

[0002] In the field of pipeline connections, pipes of different materials need to be reliably connected to ensure the safe transport of fluids. Traditional pipeline connection methods typically include welding, threaded connections, or clamp connections. However, these methods may have problems such as complex operation, long installation time, and poor sealing, especially under the special requirements of different industries, such as chemical, food, and pharmaceutical industries, where the safety, sealing, and durability requirements of pipeline connections are high.

[0003] Existing pipe connection structures typically use fittings such as clamps, connecting rings, or rubber sealing rings to enhance the connection performance between pipes. However, these traditional structures often have shortcomings in terms of connection stability, sealing performance, and corrosion resistance, especially after prolonged use, they are prone to loosening or leakage. Utility Model Content

[0004] The purpose of this utility model is to provide a connecting pipe structure that combines an annular groove with a connecting ring, which can further improve the reliability, sealing performance and service life of the connection, and has important practical application value.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A connecting pipe structure includes:

[0007] A stainless steel pipe, one end of which is deburred, and several outer annular grooves are provided at the joint of the other end of the stainless steel pipe.

[0008] A connecting hose, one end of which is set to a larger diameter, and several inner annular grooves are provided at the connection point of the connecting hose at that end;

[0009] A connecting ring is provided between the stainless steel pipe and the connecting hose. The inner side of the connecting ring is clamped on the outer annular groove of the stainless steel pipe, and the outer side is clamped in the inner annular groove of the connecting hose.

[0010] Preferably, the outer annular groove of the stainless steel tube is a plurality of annular grooves evenly distributed along the axial direction.

[0011] Preferably, the inner annular groove of the connecting hose is a plurality of annular grooves evenly distributed along the axial direction.

[0012] Preferably, the connecting ring is an annular structure, and its inner and outer sides are tightly fitted with the outer annular groove of the stainless steel tube and the inner annular groove of the connecting rubber tube, respectively.

[0013] Preferably, the connecting ring between the stainless steel tube and the connecting hose is completely abutted between the inner annular groove of the connecting hose and the outer annular groove of the stainless steel tube.

[0014] Preferably, the inner annular groove of the connecting tube engages with the outer side of the connecting ring to form a sealed connection.

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

[0016] Through the matching design of the outer and inner annular grooves between the stainless steel pipe and the connecting hose, the connecting ring can tightly clamp between the stainless steel pipe and the connecting hose, providing a more secure connection and avoiding loosening caused by external force or vibration, thereby improving the stability and safety of the connection. The tight fit between the inner side of the connecting ring and the outer annular groove of the stainless steel pipe, and the outer side and the inner annular groove of the connecting hose, not only provides mechanical fixation, but also effectively reduces the risk of liquid and air leakage at the connection point, significantly improving sealing performance and ensuring the safe transportation of fluids.

[0017] The design employs a simple clamp connection method, avoiding the complex operations of traditional welding or threaded connections. The installation process is faster, and maintenance and disassembly are convenient, greatly saving time and labor costs. The selection of stainless steel pipes and the deburring process can effectively improve the corrosion resistance of the pipes and extend their service life. The design of the connecting hoses makes them adaptable to various working environments, resisting chemical corrosion and temperature changes, and maintaining good performance for a long time.

[0022] Example

[0023] See Figure 1-2 As shown, a connecting pipe structure includes:

[0024] A stainless steel pipe 1, one end of the stainless steel pipe 1 is deburred, and several outer annular grooves 11 are provided at the other end of the stainless steel pipe 1.

[0025] A connecting hose 2, one end of which is set to a larger diameter, and a plurality of inner annular grooves 21 are provided at the connection point of the connecting hose 2 at this end;

[0026] A connecting ring 3 is provided between the stainless steel pipe 1 and the connecting hose 2. The inner side of the connecting ring 3 is clamped on the outer annular groove 11 of the stainless steel pipe 1, and the outer side is clamped in the inner annular groove 21 of the connecting hose 2.

[0027] By setting outer and inner annular grooves 21 between the stainless steel pipe 1 and the connecting hose 2, and firmly connecting the two with a connecting snap ring 3, loosening of the connection can be effectively prevented. This design ensures that the pipeline can withstand greater pressure and external force during operation, avoiding detachment or leakage at the connection due to vibration or pulling.

[0028] The combination of the inner and outer annular grooves 11 and the tight fit of the retaining ring create an excellent sealing effect during the connection process. This design reduces the possibility of liquid or air leakage at the joint, and is especially suitable for fluid transportation systems, ensuring the fluid sealing and safety of the pipeline.

[0029] This pipe connection structure uses a 3-ring fixing method, which is simpler to install and does not require special tools or high-temperature operations compared to traditional welding or threaded connections. Maintenance and disassembly are also more convenient, significantly saving time and labor and improving the operability of the pipeline.

[0030] The outer annular groove 11 of the stainless steel pipe 1 consists of multiple annular grooves evenly distributed along the axial direction; the inner annular groove 21 of the connecting rubber tube 2 consists of multiple annular grooves evenly distributed along the axial direction.

[0031] By setting multiple axially evenly distributed annular grooves on the stainless steel pipe 1 and the connecting hose 2, the contact between the connecting ring 3 and the pipe can be more uniform, reducing local pressure concentration and improving the overall stability and firmness of the connection. This design effectively avoids pipe loosening or detachment caused by uneven connection.

[0032] The design of multiple annular grooves allows the connecting ring 3 to form multiple sealing contact points during connection, thereby improving the overall sealing effect. Each annular groove increases the sealing surface, ensuring a tight seal at the pipe joint and reducing the risk of liquid or air leakage, making it particularly suitable for high-pressure or strictly sealed fluid systems.

[0033] Multiple evenly distributed grooves effectively disperse mechanical stress at the joint, reducing stress concentration and thus improving the durability and service life of the piping system. Furthermore, this design better withstands environmental changes or external vibrations, ensuring the long-term stability of the connection point.

[0034] The connecting ring 3 has an annular structure, and its inner and outer sides are tightly fitted with the outer annular groove 11 of the stainless steel tube 1 and the inner annular groove 21 of the connecting rubber tube 2, respectively; the connecting ring 3 between the stainless steel tube 1 and the connecting rubber tube 2 is completely abutted between the inner annular groove 21 of the connecting rubber tube 2 and the outer annular groove 11 of the stainless steel tube 1; the inner annular groove 21 of the connecting rubber tube 2 and the outer side of the connecting ring 3 cooperate to form a sealed connection.

[0035] The inner side of the connecting ring 3 fits tightly with the outer annular groove 11 of the stainless steel pipe 1, and the outer side fits tightly with the inner annular groove 21 of the connecting hose 2, forming a complete sealing contact surface. This design effectively prevents liquid or gas leakage, enhances the sealing performance of the connection, and ensures that the pipeline system has a highly efficient sealing effect during operation.

[0036] Because the connecting ring 3 fits snugly between the grooves of the stainless steel pipe 1 and the connecting hose 2, it ensures a secure connection that is not easily loosened. This tight fit prevents the ring from shifting or deforming under external pressure or vibration, thus increasing the overall stability of the piping system.

[0037] The snap ring design simplifies the connection between the stainless steel pipe 1 and the connecting hose 2; simply insert the snap ring and adjust it to the appropriate position to complete the connection. This design not only reduces installation difficulty but also facilitates subsequent disassembly and maintenance. It provides a more convenient operating experience for systems requiring frequent pipe inspections or replacements.

[0038] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
