Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe technology, and in particular to a stainless steel pipe that can be quickly disassembled and assembled. Background Technology

[0002] With the rapid development of building construction, pipeline installation and other fields, the performance and installation requirements of various pipe fittings are constantly increasing. Traditional stainless steel pipes have many shortcomings in terms of connection and sealing, and can no longer meet the needs of modern engineering for efficient and convenient construction.

[0003] Traditional stainless steel pipes using flange connections suffer from extremely low installation efficiency. Installation requires precise alignment of the flange bolt holes, demanding numerous collaborators and high precision; even slight deviations prevent bolts from passing through, necessitating readjustment. Tightening a large number of bolts is time-consuming and labor-intensive. In large industrial pipeline projects, installing a pair of large-specification flanges often takes hours or even longer. Furthermore, commonly used rubber seals and adhesives at pipe connections are susceptible to aging due to the influence of media, temperature, and pressure. For example, in high-temperature hot water pipes, ordinary rubber seals may harden and crack within one to two years, leading to leaks. Repairs are not only costly in terms of manpower and resources but may also impact the surrounding environment. Therefore, a type of stainless steel pipe that allows for quick assembly and disassembly is proposed to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a stainless steel pipe that can be quickly disassembled and assembled, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-assembly and disassembly stainless steel pipe includes a first steel pipe, a second steel pipe at one end of the first steel pipe, an installation assembly between the first and second steel pipes, a common sealing ring at the connection between the first and second steel pipes, two clamps symmetrically arranged on the outside of the sealing ring, a fixing plate fixedly fitted on the outside of the second steel pipe, and two long grooves on one side of the fixing plate, with an adjustment assembly and a guide assembly respectively installed in the two long grooves.

[0007] Preferably, the installation assembly includes a connecting pipe fixedly connected to one side of the first steel pipe, the connecting pipe communicating with the first steel pipe, the outer side of the connecting pipe having an external thread, and the inner side of the second steel pipe having an internal thread, the external thread and the internal thread being compatible.

[0008] Preferably, the adjustment assembly includes a circular hole on one side of a fixed plate, a bidirectional screw installed in the circular hole, one end of the bidirectional screw being rotatably connected to the inner wall of one side of the upper long groove, and two sliders being threaded onto the outer side of the bidirectional screw, with one side of each of the two clamping plates being fixedly connected to one side of each of the two sliders.

[0009] Preferably, a handwheel is fixedly connected to the other end of the bidirectional screw, and a threaded hole and multiple threaded grooves are respectively opened on one side of the handwheel and the fixed plate.

[0010] Preferably, a threaded post is threaded into a threaded hole, and the other end of the threaded post is threaded into a threaded groove that is aligned with the threaded hole.

[0011] Preferably, the guide assembly includes a guide rod fixedly installed in the lower long groove, two guide blocks slidably sleeved on the outer side of the guide rod, and the other side of the two guide blocks being fixedly connected to one side of the two clamping plates respectively.

[0012] Preferably, the inner sides of both clamps are provided with fitting grooves, and both fitting grooves are adapted to the outer side of the sealing ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By cooperating with the original sealing structure of the steel pipe, a double seal is achieved, effectively reducing the risk of media leakage. After the sealing ring is installed in place, the handwheel is turned to drive the bidirectional screw, causing the slider to move the clamping plates closer together. The fitting groove matches the height of the outer side of the sealing ring, tightly locking them together. Moreover, the guide block on the guide rod guides and limits the clamping plates, ensuring stable and vertical movement and uniform pressure distribution. Even if the sealing ring hardens or cracks, it can prevent leakage and displacement. In addition, the threaded column limits the handwheel, preventing the bidirectional screw from rotating due to water flow vibration, thus comprehensively ensuring the long-term stable and safe operation of the pipeline system.

[0015] 2. By matching the external thread on the outside of the connecting pipe with the internal thread on the inside of the second steel pipe, during installation, insert the connecting pipe into one end of the first steel pipe and rotate the second steel pipe. The threaded engagement allows the connecting pipe to extend into the first steel pipe to complete the installation. Disassembly is achieved by rotating in the opposite direction. This method eliminates the cumbersome process of aligning bolt holes in traditional flange connections, requires no multiple people to work together, and has low precision requirements, greatly improving installation efficiency. In large-scale industrial pipeline projects, it can significantly shorten installation time and reduce labor costs. At the same time, the quick disassembly and assembly feature makes it easier to replace parts during maintenance, improving the maintenance efficiency of the pipeline system.

[0021] 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.

[0022] Reference Figure 1-4A quick-assembly and disassembly stainless steel pipe includes a first steel pipe 1, a second steel pipe 4 at one end of the first steel pipe 1, an installation assembly between the first steel pipe 1 and the second steel pipe 4, a common sealing ring 6 at the connection between the first steel pipe 1 and the second steel pipe 4, two clamping plates 10 arranged symmetrically on the outside of the sealing ring 6, a fixing plate 7 fixedly fitted on the outside of the second steel pipe 4, two long grooves on one side of the fixing plate 7, an adjustment assembly and a guide assembly respectively installed in the two long grooves, an adapter groove 11 on the inner side of each of the two clamping plates 10, both adapter grooves 11 being adapted to the outer side of the sealing ring 6, the adjustment assembly including a circular hole on one side of the fixing plate 7, a bidirectional screw 8 installed in the circular hole, one end of the bidirectional screw 8 being rotatably connected to the inner wall of one side of the upper long groove, two sliders 9 threadedly fitted on the outer side of the bidirectional screw 8, one side of each of the two clamping plates 10 being respectively connected to the two sliders 9 One side of block 9 is fixedly connected. A sealing ring 6 is installed. After the first and second steel pipes are installed, the sealing ring 6 is moved to the connection between the two pipes. It works with the original sealing structure to achieve double sealing and reduce the risk of media leakage. After the sealing ring 6 is in place, turn the handwheel 12 clockwise. The handwheel 12 drives the bidirectional screw 8 to rotate. The two sliders 9 on the outside of the bidirectional screw 8 rotate synchronously with the bidirectional screw 8. They drive the two clamping plates 10 to move closer to each other along the predetermined track. The two clamping plates 10 have matching grooves 11 on opposite sides. The matching grooves 11 are designed according to the outer contour of the sealing ring 6. The two have a high degree of fit. When the two clamping plates 10 are in contact, the sealing ring 6 is completely inserted into the two matching grooves 11. This can further limit the sealing ring 6. Even if the sealing ring 6 hardens and cracks after long-term use, it can prevent leakage and displacement, ensuring the long-term stable and safe operation of the pipeline system and reducing maintenance costs and safety hazards caused by sealing failure.

[0023] Specifically, the installation assembly includes a connecting pipe 2 fixedly connected to one side of the first steel pipe 1, the connecting pipe 2 communicating with the first steel pipe 1, the outer side of the connecting pipe 2 having an external thread 3, and the inner side of the second steel pipe 4 having an internal thread 5, the external thread 3 and the internal thread 5 being compatible. By providing the connecting pipe 2, when connecting the steel pipes, the connecting pipe 2 fixedly connected to one end of the second steel pipe 4 is inserted into one end of the first steel pipe 1, and then the second steel pipe 4 is rotated. Due to the interaction between the external thread 3 and the internal thread 5, the connecting pipe 2 will gradually extend into the interior of the first steel pipe 1, thereby completing the installation between the first steel pipe 1 and the second steel pipe 4. When disassembly is required, the second steel pipe 4 can be rotated in the opposite direction. This method of easy installation and disassembly makes maintenance and installation more convenient.

[0024] Specifically, a handwheel 12 is fixedly connected to the other end of the bidirectional screw 8. A threaded hole 13 and multiple threaded grooves 14 are respectively opened on one side of the handwheel 12 and the fixing plate 7. A threaded post 15 is threadedly installed in one of the threaded holes 13. The other end of the threaded post 15 is threaded into the threaded groove 14 that is aligned with the threaded hole 13. By providing the handwheel 12, the bidirectional screw 8 can be rotated clockwise or counterclockwise, thereby controlling the two clamping plates 10 to move closer or further apart. With the threaded post 15, when the two clamping plates 10 are installed, the threaded post 15 is threaded into one of the threaded holes 13. Then, by continuing to rotate the threaded post 15, the other end of the threaded post 15 can be threaded into the aligned threaded groove 14, thereby achieving a fixed connection between the handwheel 12 and the fixing plate 7. This prevents the bidirectional screw 8 from rotating due to slight vibrations caused by the water flow in the pipe.

[0025] Specifically, the guide assembly includes a guide rod 16 fixedly installed in the lower long groove. Two guide blocks 17 are slidably sleeved on the outer side of the guide rod 16. The other side of the two guide blocks 17 is fixedly connected to one side of the two clamping plates 10 respectively. By setting two guide blocks 17, the two guide blocks 17 can guide and limit the two clamping plates 10, so that the clamping plates 10 will remain in a vertical state after long-term movement. This not only ensures the stability of the clamping plates 10 during movement, but also avoids deviation or jamming. It also ensures that the pressure applied to the two clamping plates 10 is evenly distributed when limiting the sealing ring 6, thereby maximizing the fixing effect of the sealing ring 6 and enhancing the sealing performance and reliability of the entire pipeline connection.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0027] In use: When connecting the steel pipes, insert the connecting pipe 2, which is fixedly connected to one end of the second steel pipe 4, into one end of the first steel pipe 1. Then rotate the second steel pipe 4. Due to the interaction between the external thread 3 and the internal thread 5, the connecting pipe 2 will gradually extend into the first steel pipe 1, thus completing the installation between the first steel pipe 1 and the second steel pipe 4. When disassembly is required, simply rotate the second steel pipe 4 in the opposite direction. To enhance the sealing effect, a sealing ring 6 is provided. After the first steel pipe 1 and the second steel pipe 4 are installed, move the sealing ring 6 to the connection point of the two steel pipes to achieve a double seal. After the sealing ring 6 is installed, turn the handwheel 12 clockwise to drive the double-acting screw 8 to rotate synchronously. The two sliders 9 connected by the side threads will synchronously drive the two clamping plates 10 to move closer to each other. Each of the two clamping plates 10 has an adapter groove 11 on its opposite side, and the adapter groove 11 is adapted to the outer contour of the sealing ring 6. Therefore, when the two clamping plates 10 are in contact, the sealing ring 6 is completely locked in the two adapter grooves 11, which further limits the sealing ring 6 and prevents leakage and displacement due to hardening and cracking. In addition, after the two clamping plates 10 have completed the fixing and limiting of the sealing ring 6, the threaded post 15 is used to limit the handwheel 12, which can prevent the bidirectional screw 8 from rotating due to slight vibration caused by the water flow in the pipe, and ensure that the entire connection structure is stable and reliable.
