Description

Technical Field

[0001] This utility model relates to the technical field of pipe fitting sealing, and in particular to a sealing and locking structure for water supply pipe fittings. Background Technology

[0002] In water supply and drainage systems, the sealing performance of water supply pipe fittings is crucial, as it directly affects whether the system can operate stably and efficiently, and whether problems such as water waste and damage to the surrounding environment of the pipeline will occur.

[0003] Traditional water supply pipe connection methods, such as threaded connections and welding, have many drawbacks. After prolonged use, threaded connections are prone to loosening due to pipe vibration, thermal expansion and contraction, leading to decreased sealing performance and leaks. While welding can ensure a certain degree of sealing, the welding process requires highly skilled workers, and the high temperatures generated can damage the pipe material, affecting its lifespan. Furthermore, welded pipes are difficult to disassemble, causing significant inconvenience during pipe maintenance or system upgrades.

[0004] Existing sealing structures often fail to provide adequate sealing in complex working environments, such as those with significant pressure fluctuations or corrosive water. Furthermore, single sealing methods cannot meet the stringent performance requirements, and they lack convenient and effective operation methods during installation and maintenance. Therefore, a new sealing and locking structure for water supply pipe fittings is urgently needed. Utility Model Content

[0035] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0036] like Figures 1 to 5 As shown, the present invention provides a sealing and locking structure for water supply pipe fittings, comprising:

[0037] Pipe A11 is used to transport water.

[0038] Pipe B12 is connected to pipe A11 and is used to transport water.

[0039] A sealing ring 13 is provided at the connection ports of pipe A 11 and pipe B 12, and pipe A 11 and pipe B 12 are tightly connected through the sealing ring 13.

[0040] Water-proof ring 14 is provided on the outer wall of both pipe A 11 and pipe B 12. A sealing groove is provided between the water-proof ring 14 and the sealing ring 13.

[0041] Multiple sealing rings 15, with two sealing rings 15 in each group of sealing ring grooves, and one sealing ring 15 on the outer side of each water-proof ring 14;

[0042] The clamping mechanism 2 is clamped on the connection port between pipe A 11 and pipe B 12, and is used to clamp the sealing ring 15 to seal the pipe fitting;

[0043] The working process and principle of this structure are as follows: Sealing rings 13 are provided at the connection ports of pipes A 11 and B 12. When pipes A and B need to be connected, preliminary docking is first achieved through the sealing rings 13, ensuring a tight fit between the pipes and forming a preliminary sealing barrier. Water-proof rings 14 are provided on the outer walls of pipes A 11 and B 12. Sealing grooves are provided between the water-proof rings 14 and the sealing rings 13, with two sealing rings 15 installed in each groove. A sealing ring is also provided on the outer side of each water-proof ring. The combination of the water-proof rings and the sealing rings enhances the sealing effect, effectively preventing water penetration and ensuring the reliability of the seal even in corrosive water or under conditions of large pressure fluctuations. A clamping mechanism 2 is clamped at the connection port of pipes A 11 and B 12. The function of the clamping mechanism is to clamp the sealing rings 15. This further enhances the sealing effect; the mechanical action of the clamping mechanism ensures that the sealing ring fits tightly between the water-proof ring and the sealing ring, forming a stable sealing layer; this sealing locking structure achieves basic sealing between pipe fittings through the initial connection of the sealing ring; the multiple sealing design of the water-proof ring and the sealing ring improves the reliability and durability of the seal; the introduction of the clamping mechanism strengthens the sealing effect mechanically, ensuring the long-term stability of the seal; this water supply pipe fitting sealing locking structure effectively solves the problems of decreased sealing performance, leakage, and inconvenient installation and maintenance that exist in traditional water supply pipe fitting connection methods through the initial connection of the sealing ring, the multiple sealing between the water-proof ring and the sealing ring, and the reinforced sealing by the clamping mechanism; it not only improves the reliability and durability of the seal, but also simplifies the installation and maintenance process, improving work efficiency and convenience.

[0044] The clamping mechanism 2 includes:

[0045] Two pressure rings 21 are hinged together, and the pressure rings 21 are set in a semi-circular arc shape;

[0046] Two locking components are respectively disposed on the two pressure rings 21, and are used to lock the two pressure rings 21 when they are closed;

[0047] The locking components include:

[0048] Spring plate 23 is fixedly mounted on pressure ring 21, and two springs 24 are provided on spring plate 23.

[0049] Two locking sleeves 25 are respectively fitted onto two spring pieces 24, and the locking sleeves 25 are provided with slots 26.

[0050] Pin 27 is rotatably inserted into two locking sleeves 25;

[0051] When the two pressure rings 21 close to tighten the connection between pipe A 11 and pipe B 12, the two locking components will contact each other, and the locking sleeves 25 on both sides will contact the pins 27 on the other side respectively. Then, under the action of external force, the spring piece 24 will be deformed, which will drive the locking sleeve 25 to swing. Then the two pressure rings 21 will dock, and at this time the slot 26 will be locked on the pin 27 on the other side, realizing the locking function. The clamping mechanism 2 is composed of two semi-circular pressure rings 21. These two pressure rings are hinged and can rotate around the hinge point to realize the opening and closing action. When sealing the connection between pipe A 11 and pipe B 12 is required, the operator closes the two pressure rings 21 from both sides towards the middle, so that they tightly wrap around the connection between pipes A and B. Each pressure ring 21 is equipped with a locking assembly, which includes a spring plate 23, two springs 24, two locking sleeves 25, and a pin 27. When the two pressure rings 21 are closed, their locking assemblies will contact each other. At this time, the locking sleeve 25 on one side will contact the pin 27 on the other side. Under the action of external force, the spring 24 will be pressed and undergo elastic deformation. The deformation of the spring 24 causes the locking sleeve 25 to swing. Since the locking sleeve 25 is fitted onto the spring 24, it moves with the deformation of the spring. When the two pressure rings 21 are fully engaged, the slot 26 on the locking sleeve 25 will precisely engage with the pin 27 on the other side. At this time, due to the elastic restoring force of the spring 24, the locking sleeve 25 will tightly hold the pin 27, thus achieving the locking function. The spring 24 is a key component in the locking assembly; it uses its own elastic deformation to absorb external force and returns to its original shape after the external force is removed. The locking sleeve 25 and The combination of pins 27 constitutes a mechanical locking mechanism; when the slot 26 is engaged with the pin 27, the locking sleeve 25 will tightly fix the pin 27 due to the elastic restoring force of the spring 24, thereby preventing the two pressure rings 21 from separating; the clamping mechanism makes the installation and maintenance process very convenient; the operator only needs to simply close the two pressure rings 21 and use the elastic deformation and mechanical locking function of the locking assembly to achieve a tight sealing connection; it not only improves the reliability of the sealing performance, but also simplifies the installation and maintenance process, and improves the efficiency and convenience of the work.

[0052] The locking sleeve 25 and the spring piece 24 are fixedly connected by welding; the welded connection has extremely high strength and can withstand large tensile and compressive forces, ensuring the stability and reliability of the clamping mechanism during long-term use; the welded connection is a permanent connection method, and once formed, it cannot be easily separated, thus ensuring that the clamping mechanism will not affect the sealing effect due to loosening during use; it ensures the stability and reliability of the clamping mechanism in the water supply and drainage system and effectively improves the sealing performance of water supply pipe fittings.

[0053] The end of the locking sleeve 25 is provided with a beveled guide edge 28 to guide the pin shaft 27 to slide into the slot 26. When it is necessary to connect and seal pipe A 11 and pipe B 12, the operator will close the two pressure rings 21 so that they surround the connection port of the pipe fitting. During the closing process, the two locking components will gradually approach each other until they contact each other. After the locking components contact each other, the external force will continue to act on the pressure rings 21, causing the spring piece 24 to be compressed and elastically deformed. The deformation of the spring piece 24 will cause the locking sleeve 25 to swing, so that the end of the locking sleeve 25... The portion with the inclined guide edge 28 moves closer to the pin 27. The inclined guide edge 28 at the end of the locking sleeve 25 is designed to be relatively inclined, so that when the locking sleeve 25 swings, the inclined guide edge 28 will contact the pin 27 and guide the pin 27 to slide along the inclined surface of the inclined guide edge 28. As the locking sleeve 25 continues to swing, the pin 27 will be gradually guided to the position of the slot 26 and eventually slide into the slot 26. Through the guiding effect of the inclined guide edge, the elastic deformation of the spring piece, and the tight fit between the locking sleeve and the pin, the pressing mechanism is successfully locked and reliably sealed.

[0054] The locking sleeve 25 has a dome 29 at its end, which is located on top of the inclined guide edge 28. When the pin 27 slides to the top of the inclined guide edge 28, it contacts the dome 29. The design of the dome 29 allows the pin 27 to smoothly transition to the position of the slot 26, while also providing a certain degree of buffering and positioning. Guided and buffered by the dome 29, the pin 27 smoothly slides into the slot 26. The design of the inclined guide edge 28 and the dome 29 forms a smooth transition surface, allowing the pin 27 to maintain a stable trajectory and direction during sliding. This reduces the resistance and friction of the pin 27 during sliding, improving locking efficiency. The design of the dome 29 provides a buffer area for the pin 27, allowing it to gradually decelerate and accurately position itself before sliding into the slot 26. This helps reduce the impact and wear of the pin 27 on the slot 26, extending the service life of the clamping mechanism.

[0055] An inner bushing 22 is provided on the inner wall of the pressure ring 21; when the two pressure rings 21 are closed, they contact the outer walls of pipe A 11 and pipe B 12 through the inner bushing 22; the inner bushing 22 provides an intermediate layer between the pressure ring 21 and the pipe fitting, making the clamping force more uniform and distributed; the inner bushing 22 can protect the outer walls of the pressure ring 21 and the pipe fitting from direct friction and damage, extending their service life; the inner bushing 22 has a certain elasticity, which can adapt to the slight deformation or irregular shape of the outer wall of the pipe fitting, ensuring the reliability of clamping and sealing.

[0056] A sealing ring is provided at the port of the pressure ring 21 to protect the inside of the pressure ring 21. When the two pressure rings 21 are closed, their ports will fit against the outer walls of pipe A 11 and pipe B 12. Due to its soft and elastic properties, the sealing ring can fit tightly against the outer walls of pipe A 11 and pipe B 12 to form a seal. The sealing ring is further enhanced by the compression of the pressure ring 21, effectively preventing external fluids or impurities from entering the inside of the pressure ring 21. The sealing ring not only provides a sealing function, but also plays a certain role in protecting the inside of the pressure ring 21. It prevents external fluids or impurities from corroding or contaminating the inside of the pressure ring 21, extending the service life of the pressure ring 21. The sealing ring has good elasticity and adaptability, and can adapt to the slight deformation or displacement of the pressure ring 21 during long-term use. At the same time, it also has excellent durability and anti-aging properties, and can maintain stable sealing performance in harsh working environments.

[0057] The spring 24 and the spring seat plate 23 are integrally formed. During the manufacturing process, the spring 24 and the spring seat plate 23 are processed by integral forming technology, which ensures a seamless connection between the spring 24 and the spring seat plate 23, avoiding the loosening or breakage problems caused by traditional connection methods. The integral forming structure eliminates the connection interface between the spring 24 and the spring seat plate 23, avoiding loosening or breakage caused by defects in the connection interface, and enhancing the connection strength. The integral forming structure ensures that the relative position between the spring 24 and the spring seat plate 23 remains fixed, avoiding unstable locking or failure caused by loose connection. It improves the overall stability and reliability of the locking assembly, enabling the water supply pipe fitting sealing locking structure to maintain stable sealing performance during long-term operation.

[0058] The sealing and locking structure for water supply pipe fittings of this utility model can be installed, connected or set in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effect.

[0059] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
