Technical Field
[0001] This utility model relates to the field of spiral wound tube assembly technology, specifically a double high-rib spiral wound tube that is easy to connect. Background Technology
[0002] Double-high-strength spiral wound pipe is an all-plastic pipe made primarily of high-density polyethylene and reinforced with polypropylene corrugated pipe structure. It features high ring stiffness, flexibility, and corrosion resistance.
[0003] Existing double-high-strength spiral wound pipe connection structures, such as the HDPE plastic-steel spiral wound pipe for easy connection proposed in publication number CN223242286U, include a first pipe body, a second pipe body, and a connecting ring. A first limiting ring is sleeved on the outer side of the first pipe body, and a second limiting ring is sleeved on the outer side of the second pipe body. Threaded grooves are opened on the inner sides of both the first and second limiting rings. First bolts pass through both sides of one end of the first limiting ring, and first nuts are threaded on the outer sides of both first bolts. Second bolts pass through both sides of one end of the second limiting ring, and second nuts are threaded on the outer sides of both second bolts. This utility model has the advantage of pulling the first and second pipe bodies to move towards each other and pressing and connecting them within the connecting ring, thereby improving the connection efficiency of the HDPE plastic-steel spiral wound pipe. While existing spiral wound tubes can improve the efficiency of connection, it has been found in practice that connecting spiral wound tubes requires multiple bolts and nuts, which not only necessitates aligning the bolt holes but also tightening multiple bolts and nuts, resulting in a slow connection speed and inconvenience. Therefore, we propose a double-high-rib spiral wound tube that facilitates connection to solve the aforementioned problems. Utility Model Content
[0004] The purpose of this utility model is to provide a double-high-rib winding tube that is easy to connect, so as to solve the problems in the current market mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-high-rib winding tube for easy connection, comprising winding tubes, a connecting tube disposed between the winding tubes, and annular slots symmetrically provided at both ends of the connecting tube, wherein... The end of the winding tube corresponding to the annular slot is connected to an insertion tube. A first sealing ring is provided at equal intervals between the annular slot and the inner wall of the insertion tube. A slot is provided at equal intervals on the outer side of the insertion tube. A transmission groove is provided at equal intervals on the inner wall of the annular slot. A connecting frame is provided in the transmission groove. A guide rod groove is connected to the outer side of the connecting tube corresponding to the transmission groove. A guide rod is fixedly connected to one side of the connecting frame corresponding to the guide rod groove. A baffle is fixedly connected to the end of the guide rod away from the connecting frame. A spring is sleeved on the guide rod between the connecting frame and the inner wall of the transmission groove. A locking block is fixedly connected at equal intervals to the side of the connecting frame corresponding to the locking groove. A push rod groove is connected to the end of the connecting tube corresponding to the transmission groove. A push rod passes through the push rod groove. The push rods at the same end of the connecting tube are fixedly connected by an annular frame. The connection structure between the winding tube and the connecting tube is sealed by a sealing mechanism.
[0006] Preferably, the slot is an annular slot, and the sidewall of the slot facing the connecting pipe is an inclined surface, and the internal dimensions of the slot cross-section match the external dimensions of the card block.
[0007] Preferably, the end of the connecting frame near the push rod is an inclined surface, and the end of the push rod near the connecting frame is a spherical surface.
[0008] Preferably, the guide rod and the guide rod groove form a guiding structure, and the inner diameter of the guide rod groove is smaller than the outer diameter of the baffle.
[0009] Preferably, the connecting pipe is connected to a limiting groove on one side of the middle part of the push rod groove, and the push rod is fixedly connected to a limiting plate on the outside of the limiting groove.
[0010] Preferably, the sealing mechanism includes a second sealing ring, the outer wall of the insertion tube corresponding to the opening of the annular slot is equipped with the second sealing ring, the openings at both ends of the push rod groove are equipped with a third sealing ring for sealing connection with the push rod, and the inner wall of the guide rod groove is equipped with a fourth sealing ring for sealing connection with the guide rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, when connecting two spiral tubes, the spiral tube drives the insert tube to be inserted into the annular slot of the connecting tube. During insertion, the insert tube abuts against the inclined surface of the locking block, causing the locking block to retract into the transmission groove against the spring force. After the insert tube is fully inserted into the annular slot, the spring drives the locking block to reset, allowing the locking block to be inserted into the slot, thus fixing the connection between the connecting tube and the spiral tube. Both ends of the connecting tube are fixedly connected to the two spiral tubes respectively, thereby enabling a quick connection between the spiral tubes. The connection between the spiral tube and the connecting tube is sealed by the first sealing ring, effectively improving the connection speed between the spiral tubes.
[0012] This invention allows for the disassembly of the winding tube and the connecting tube when the ring frame is pushed, causing it to move towards the connecting tube. This causes the ring frame to push the push rod, and when the end of the push rod abuts against the inclined surface of the connecting frame, the connecting frame moves the locking block out of the slot against the spring force. This allows the insertion tube to be directly moved out of the ring slot. Through the designed disassembly components, the winding tube can be quickly connected and quickly disassembled at the same time.
[0013] In this invention, after the winding tube and the connecting tube are connected, a second sealing ring is used to seal the connection between the insertion tube and the opening of the annular slot, a third sealing ring is used to seal the connection between the push rod and the push rod groove, and a fourth sealing ring is used to seal the connection between the guide rod groove and the guide rod. Through the sealing mechanism, the installation and disassembly components between the winding tube and the connecting tube can be sealed, preventing corrosion of the installation and disassembly components, improving the stability of the winding tube connection, and preventing corrosion of the installation and disassembly components from making disassembly impossible.

[0016] 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.
[0017] Please see Figures 1 to 3 This utility model provides a technical solution: a double-high-rib winding tube for easy connection, comprising a winding tube 1, a connecting tube 2 disposed between the winding tubes 1, and annular slots 3 symmetrically opened at both ends of the connecting tube 2, wherein... The end of the winding tube 1 corresponding to the annular slot 3 is connected to the insertion tube 4. The inner wall of the annular slot 3 and the insertion tube 4 are provided with a first sealing ring 5 at equal intervals. The outer side of the insertion tube 4 is provided with a slot 6 at equal intervals. The inner wall of the annular slot 3 is provided with a transmission groove 7 at equal intervals. A connecting frame 8 is provided in the transmission groove 7. The outer side of the connecting tube 2 corresponding to the transmission groove 7 is connected to the guide rod groove 9. The connecting frame 8 is fixedly connected to the guide rod groove 9 on one side. A baffle 11 is fixedly connected to the end of the guide rod 10 away from the connecting frame 8. A spring 12 is sleeved on the guide rod 10 between the connecting frame 8 and the inner wall of the transmission groove 7. A locking block 13 is fixedly connected at equal intervals to one side of the connecting frame 8 corresponding to the locking groove 6. A push rod groove 14 is connected to the end of the connecting pipe 2 corresponding to the transmission groove 7. A push rod 15 passes through the push rod groove 14. The push rods 15 at the same end of the connecting pipe 2 are fixedly connected by a ring frame 16. The connection structure between the winding pipe 1 and the connecting pipe 2 is sealed by a sealing mechanism. When connecting the winding tubes 1, the winding tube 1 drives the insertion tube 4 to be inserted into the annular slot 3 of the connecting tube 2. During insertion, the insertion tube 4 abuts against the inclined surface of the locking block 13, causing the locking block 13 to retract into the transmission groove 7 against the elastic force of the spring 12. After the insertion tube 4 is fully inserted into the annular slot 3, the spring 12 drives the locking block 13 to reset, causing the locking block 13 to be inserted into the locking groove 6, thus fixing the connection between the connecting tube 2 and the winding tube 1. The two ends of the connecting tube 2 are respectively fixedly connected to the two winding tubes 1, thereby enabling a quick connection between the winding tubes 1. The connection between the winding tube 1 and the connecting tube 2 is sealed by the first sealing ring 5, effectively improving the connection speed between the winding tubes 1.
[0018] Please see Figures 1 to 3 The slot 6 is an annular groove, and the side wall of the slot 6 facing the connecting tube 2 is an inclined surface. The internal dimensions of the slot 6 are consistent with the external dimensions of the block 13. The end of the connecting frame 8 near the push rod 15 is an inclined surface, and the end of the push rod 15 near the connecting frame 8 is a spherical surface. When it is necessary to disassemble the winding tube 1 and the connecting tube 2, the annular frame 16 is pushed, causing the annular frame 16 to move towards the connecting tube 2. The annular frame 16 pushes the push rod 15 to move. When the end of the push rod 15 abuts against the inclined surface of the connecting frame 8, the connecting frame 8 drives the block 13 to overcome the elastic force of the spring 12 and move out of the slot 6. This allows the insertion tube 4 to be directly moved out of the annular slot 3. Through the disassembly components, the winding tube 1 can be quickly connected and disassembled at the same time.
[0019] Please see Figures 1 to 3 The guide rod 10 and the guide rod groove 9 form a guide structure, and the inner diameter of the guide rod groove 9 is smaller than the outer diameter of the baffle 11. The connecting pipe 2 is connected to the limiting groove 17 on one side of the middle part of the push rod groove 14. The push rod 15 is fixedly connected to the limiting plate 18 on the outer side of the limiting groove 17. When the push rod 15 moves, the push rod 15 drives the limiting plate 18 to move in the limiting groove 17. Through the limiting plate 18 and the limiting groove 17, the movement of the push rod 15 can be limited to prevent the push rod 15 from moving out of the push rod groove 14.
[0020] Please see Figures 1 to 3The sealing mechanism includes a second sealing ring 19. The second sealing ring 19 is installed on the outer wall of the insertion tube 4 corresponding to the opening of the annular slot 3. The openings at both ends of the push rod groove 14 are equipped with a third sealing ring 20 for sealing connection with the push rod 15. The inner wall of the guide rod groove 9 is equipped with a fourth sealing ring 21 for sealing connection with the guide rod 10. After the winding tube 1 and the connecting tube 2 are connected, the second sealing ring 19 seals the connection between the insertion tube 4 and the opening of the annular slot 3, the third sealing ring 20 seals the connection between the push rod 15 and the push rod groove 14, and the fourth sealing ring 21 seals the connection between the guide rod groove 9 and the guide rod 10. Through the sealing mechanism, the installation and disassembly components between the winding tube 1 and the connecting tube 2 can be sealed, avoiding corrosion of the installation and disassembly components, improving the stability of the connection of the winding tube 1, and preventing the installation and disassembly components from being unable to be disassembled due to corrosion.
[0021] Working Principle: This type of double-high-rib spiral wound tube facilitates connection. When connecting spiral wound tubes 1, the spiral wound tube 1 drives the insert tube 4 to insert into the annular slot 3 of the connecting tube 2. During insertion, the insert tube 4 abuts against the inclined surface of the locking block 13, causing the locking block 13 to retract into the transmission groove 7 against the elastic force of the spring 12. After the insert tube 4 is fully inserted into the annular slot 3, the spring 12 drives the locking block 13 to reset, causing the locking block 13 to insert into the locking groove 6, thus fixing the connection between the connecting tube 2 and the spiral wound tube 1. Both ends of the connecting tube 2 are fixedly connected to the two spiral wound tubes 1 respectively, thereby enabling quick connection between the spiral wound tubes 1. The first sealing ring 5 seals the connection between the winding tube 1 and the connecting tube 2, effectively improving the connection speed between the winding tube 1 and the connecting tube 2. When it is necessary to disassemble the winding tube 1 and the connecting tube 2, push the ring frame 16 to move the ring frame 16 towards the connecting tube 2, so that the ring frame 16 pushes the push rod 15 to move. When the end of the push rod 15 abuts against the inclined surface of the connecting frame 8, the connecting frame 8 drives the locking block 13 to overcome the elastic force of the spring 12 and move out of the inside of the locking slot 6, so that the insertion tube 4 can be directly moved out of the inside of the ring slot 3. Through the disassembly component, the winding tube 1 can be quickly connected and disassembled at the same time. When the push rod 15 moves, the push rod 15 drives the limiting plate 18 to move within the limiting groove 17. The limiting plate 18 and the limiting groove 17 limit the movement of the push rod 15, preventing the push rod 15 from moving out of the push rod groove 14. After the winding tube 1 and the connecting tube 2 are connected, the second sealing ring 19 seals the connection between the insertion tube 4 and the opening of the annular slot 3. The third sealing ring 20 seals the connection between the push rod 15 and the push rod groove 14. The fourth sealing ring 21 seals the connection between the guide rod groove 9 and the guide rod 10. The sealing mechanism can seal the installation and disassembly components between the winding tube 1 and the connecting tube 2, preventing corrosion of the installation and disassembly components, improving the stability of the connection of the winding tube 1, and preventing corrosion of the installation and disassembly components that would prevent disassembly.
