Abstract
Description
Technical Field
[0001] This utility model relates to the field of corrugated pipe technology, and in particular to stainless steel corrugated pipe assemblies. Background Technology
[0002] Stainless steel corrugated pipes are installed in liquid transportation systems as a type of flexible pressure-resistant pipe fitting to compensate for the mutual displacement of pipe or machine / equipment connection ends, absorb vibration energy, and play a role in vibration reduction and noise reduction. They have many characteristics such as good flexibility, light weight, corrosion resistance, fatigue resistance, and resistance to high and low temperatures.
[0003] Chinese utility model patent CN221897303U discloses a stainless steel corrugated pipe, relating to the field of stainless steel corrugated pipe technology. It includes a corrugated connecting pipe with a second connector installed at one end. Symmetrically arranged on the outer side of the second connector are disassembly and assembly components. These components facilitate the disassembly and assembly of the corrugated pipe connection. Each component includes an installation groove and a lever. The installation groove is located on the outer side of the second connector, and a connecting shaft is installed at the rotating end of the lever, with the connecting shaft installed inside the installation groove. In this utility model, because the lever is mounted via the connecting shaft, the user can rotate the lever to the outer side, providing a leverage position for rotating the first and second connectors, assisting in the installation of the corrugated connecting pipe. This facilitates the connection and disassembly of the corrugated connecting pipe, providing a labor-saving and anti-slip function.
[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: While the device reduces the difficulty for workers to rotate the bellows through the force-operated handle, thereby reducing the difficulty for workers to connect the first and second connectors to other pipes, in actual use, when the force-operated handle is placed in the mounting groove, the anti-slip groove and the limiting pad abut against each other, improving the stability of the force-operated handle. However, this also increases the difficulty for workers to remove the handle; workers without fingernails will find it difficult to remove the force-operated handle, resulting in a poor user experience. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a stainless steel corrugated pipe assembly.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stainless steel corrugated pipe assembly, including a corrugated connecting pipe and two connectors respectively installed at both ends of the corrugated connecting pipe. Two mutually symmetrical rotating grooves are opened on the side wall of the connector. A rotating rod is rotatably arranged on the inner wall of the rotating groove. An arc-shaped piece is fixed on the rotating rod. A placement groove is opened on the inner wall of the arc-shaped piece. A return spring is fixed on the inner wall of the placement groove. A limiting component for limiting the arc-shaped piece is provided on the connector.
[0007] By adopting the above technical solution, when workers need to install corrugated pipes, they need to connect the two connectors to both ends of the corrugated pipe respectively, and then connect the two connectors to other pipes in sequence. At this time, in order to reduce the difficulty for workers to rotate the connectors, the limiting component needs to be closed, which allows the arc-shaped plate to automatically pop outward under the action of the return spring. This reduces the difficulty for workers to separate one end of the arc-shaped plate from the rotating groove, thereby reducing the difficulty for workers to rotate the connectors subsequently.
[0008] Furthermore, the corrugated connecting pipe includes a corrugated main pipe and two mounting pipes that are respectively connected to both ends of the corrugated main body.
[0009] Furthermore, a limiting groove is formed on the inner wall of the rotating groove, and the limiting component includes a limiting block slidably disposed in the limiting groove, a first magnet block fixed on the side wall of the limiting block, a second magnet block fixed on the inner wall of the limiting groove, and a driving device disposed on the connector for driving the limiting block, wherein the first magnet block and the second magnet block repel each other.
[0010] Furthermore, an inclined surface is provided on the edge where the upper surface of the limiting block intersects with the side wall away from the first magnet block.
[0011] By adopting the above technical solution, when the operator does not need to use the arc-shaped piece, the operator only needs to reset the arc-shaped piece and press it down to make it press against the inclined surface. This allows the limiting block to move completely into the limiting groove under the action of the arc-shaped piece. Subsequently, after the arc-shaped piece passes the limiting block, the limiting block pops outward under the combined action of the first and second magnets, thus blocking the arc-shaped piece and reducing the probability of the arc-shaped piece interfering with the operator's operation, thereby improving the operator's user experience.
[0012] Furthermore, a connecting rope is fixed to the side wall of the limiting block near the second magnet block, and the other end of the connecting rope is fixed to the inner wall of the limiting groove.
[0013] By adopting the above technical solution, the connecting rope blocks the limiting block, thereby reducing the probability of the limiting block and the limiting groove separating from each other, and thus improving the user experience of the device.
[0014] Furthermore, sliding grooves are provided on the two inner walls opposite to each other of the rotating groove. The driving device includes a sliding plate that is slidably disposed in the two sliding grooves and a compression spring with one end fixed to the bottom surface of the sliding plate. The other end of the compression spring is fixed to the inner bottom wall of the sliding groove.
[0015] By adopting the above technical solution, when workers need to connect the connector to other pipes, they must press the connector against the end of the other pipe and rotate the connector. To reduce the difficulty of rotating the connector, workers need to separate one end of the arc-shaped piece from the rotating groove. At this time, workers need to press the sliding plate, which will move the sliding plate downward and press against the inclined surface, thereby moving the limiting block completely into the limiting groove. Then, one end of the arc-shaped piece will automatically pop out under the action of the return spring, thus reducing the difficulty of operation for workers.
[0016] Furthermore, the surface of the corrugated connecting pipe is provided with a copper plating layer, the thickness of which is 0.01-0.025 mm.
[0017] By adopting the above technical solution, the copper plating layer improves the wear resistance of the corrugated pipe, thereby extending its service life and enhancing its aesthetics.
[0018] Furthermore, the corrugated main pipe has right-handed corrugations, and the spacing between two corrugations on the corrugated main pipe is 3.5 mm.
[0019] Furthermore, the inner diameter of the corrugated main pipe is 8.4 mm, and the outer diameter of the corrugated main pipe is 11.5 mm.
[0020] Furthermore, the corrugated connecting pipe is a corrugated connecting pipe made of stainless steel.
[0021] By adopting the above technical solutions, stainless steel has good corrosion resistance, and corrugated connecting pipes made of stainless steel have good corrosion resistance, thereby further extending the service life of corrugated connecting pipes.
[0022] In summary, this utility model has the following beneficial effects:
[0023] 1. In this application, when workers need to install corrugated pipes, they need to connect two connectors to both ends of the corrugated pipe and then connect the two connectors to other pipes in sequence. To reduce the difficulty for workers to rotate the connectors, the limiting component is closed, allowing the arc-shaped plate to automatically pop outward under the action of the return spring. This reduces the difficulty for workers to separate one end of the arc-shaped plate from the rotating groove, thereby reducing the difficulty for workers to rotate the connectors subsequently.
[0024] 2. In this application, when the operator does not need to use the arc-shaped piece, the operator only needs to reset the arc-shaped piece and press it down to make it press against the inclined surface, thereby causing the limiting block to move completely into the limiting groove under the action of the arc-shaped piece. Subsequently, after the arc-shaped piece passes the limiting block, the limiting block pops outward under the combined action of the first magnet and the second magnet, thereby blocking the arc-shaped piece and reducing the probability that the arc-shaped piece will interfere with the operator's operation, thus improving the operator's user experience;
[0025] 3. In this application, when the operator needs to connect the connector to other pipes, the operator needs to press the connector against the end of the other pipe and rotate the connector. To reduce the difficulty for the operator in rotating the connector, the operator needs to separate one end of the arc-shaped piece from the rotating groove. At this time, the operator needs to press the sliding plate, which will move the sliding plate downward and press against the inclined surface, thereby moving the limiting block completely into the limiting groove. Then, one end of the arc-shaped piece will automatically pop out under the action of the return spring, thus reducing the difficulty of operation for the operator. Attached Figure Description

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0034] like Figure 1-6 As shown in the embodiment of this application, a stainless steel corrugated pipe assembly is disclosed, including a corrugated connecting pipe 1, a connector 2, a rotating rod 3, an arc-shaped plate 31, a return spring 4, a limiting component 5, and a connecting rope 7. Two connectors 2 are provided and respectively installed at both ends of the corrugated connecting pipe 1. Two symmetrical rotating grooves 21 are formed on the side wall of the connector 2. The rotating rod 3 is a cylindrical structure and is rotatably mounted on the inner wall of the rotating groove 21. The arc-shaped plate 31 is a plate-shaped structure with an arc-shaped cross-section and is fixed to the rotating rod 3. A mounting groove 32 is formed on the inner wall of the arc-shaped plate 31, and the return spring 4 is fixed to the inner wall of the mounting groove 32.
[0035] The corrugated connecting pipe 1 includes a corrugated main pipe 11 and an mounting pipe 12. The corrugations on the main pipe 11 are right-handed, with a spacing of 3.5 mm between two corrugations. The width of a single corrugation on the main pipe 11 is 2 mm. The inner diameter of the main pipe 11 is 8.4 mm, and its outer diameter is 11.5 mm. The mounting pipe 12 is a cylindrical structure, with two pipes connected to both ends of the corrugated main body. The diameter of the mounting pipe 12 is 9 mm. The length of the mounting pipe 12 is 40 mm, and the length of the corrugated main pipe 11 is 2920 mm. After production, the corrugated main pipe 11 undergoes quality inspection. It must be repeatedly bent more than 30 times, with the bending wheel diameter being three times the pipe diameter, without any defects appearing.
[0036] A limiting groove 41 is formed on the inner wall of the rotating groove 21. A limiting component 5 is set on the connector 2 to limit the arc-shaped piece 31. The limiting component 5 includes a limiting block 51, a first magnet block 52, a second magnet block 53, and a driving device 6. The limiting block 51 is a rectangular block structure. The limiting block 51 is slidably disposed in the limiting groove 41, and an inclined surface is formed on the edge where the upper surface of the limiting block 51 intersects with the side wall away from the first magnet block 52. The first magnet block 52 is a circular block structure and is fixed to the side wall of the limiting block 51. The second magnet block 53 is a circular block structure and is fixed to the inner wall of the limiting groove 41. The first magnet block 52 and the second magnet block 53 repel each other.
[0037] When the operator does not need to use the arc-shaped piece 31, they simply need to reset it and press it down to press it against the inclined surface. This allows the limiting block 51 to move completely into the limiting groove 41 under the action of the arc-shaped piece 31. Subsequently, after the arc-shaped piece 31 passes the limiting block 51, the limiting block 51 pops outward under the combined action of the first magnet 52 and the second magnet 53, thus blocking the arc-shaped piece 31. This reduces the probability that the arc-shaped piece 31 will interfere with the operator's operation, thereby improving the operator's user experience.
[0038] Sliding grooves 54 are provided on the two opposing inner walls of the rotating groove 21. The driving device 6 is mounted on the connector 2 and is used to drive the limiting block 51. The driving device 6 includes a sliding plate 61 and a compression spring 62. The sliding plate 61 is a rectangular plate structure and is slidably disposed in the two sliding grooves 54. One end of the compression spring 62 is fixed to the bottom surface of the sliding plate 61, and the other end of the compression spring 62 is fixed to the inner bottom wall of the sliding groove 54.
[0039] When the operator needs to connect connector 2 to other pipes, they must press connector 2 against the end of the other pipe and rotate connector 2. To reduce the difficulty of rotating connector 2, the operator needs to separate one end of the arc-shaped piece 31 from the rotating groove 21. At this time, the operator needs to press the sliding plate 61, which will move the sliding plate 61 downward and press against the inclined surface, thereby moving the limiting block 51 completely into the limiting groove 41. Then, one end of the arc-shaped piece 31 will automatically pop out under the action of the return spring 4, thus reducing the difficulty of operation for the operator.
[0040] One end of the connecting rope 7 is fixed to the side wall of the limiting block 51 near the second magnet block 53, and the other end of the connecting rope 7 is fixed to the inner wall of the limiting groove 41. The connecting rope 7 blocks the limiting block 51, thereby reducing the probability of the limiting block 51 and the limiting groove 41 separating from each other, thus improving the user experience of the device.
[0041] A copper plating layer is applied to the surface of the corrugated connecting pipe 1 (not shown in the figure), and the thickness of the copper plating layer is 0.01-0.025 mm. The copper plating layer improves the wear resistance of the corrugated connecting pipe 1, thereby extending the service life of the corrugated connecting pipe 1 and improving the aesthetics of the corrugated connecting pipe 1.
[0042] To extend the service life of the corrugated connecting pipe 1, it is made of stainless steel. Stainless steel has excellent corrosion resistance, and the corrugated connecting pipe 1 made of stainless steel has excellent corrosion resistance, thus further extending its service life.
[0043] The working principle of the stainless steel corrugated pipe assembly in this embodiment is as follows: When the worker needs to install the corrugated pipe, the worker needs to connect the two connectors 2 to both ends of the corrugated connecting pipe 1 respectively, and then connect the two connectors 2 to other pipes in sequence. At this time, in order to reduce the difficulty for the worker to rotate the connectors 2, the worker needs to close the limiting component 5, so that the arc-shaped piece 31 can automatically pop outward under the action of the return spring 4, thereby reducing the difficulty for the worker to separate one end of the arc-shaped piece 31 from the rotating groove 21, thus reducing the difficulty for the worker to rotate the connectors 2 subsequently.
[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
