Description

Technical Field

[0001] This utility model belongs to the field of heating pipeline technology, and specifically relates to a heating pipeline protection device. Background Technology

[0002] Heating pipes are a key component of heating systems, responsible for transporting hot water or steam generated by the heat source to various heating areas. They are typically made of materials such as steel or plastic pipes, possessing good heat and pressure resistance. Various pipe connection methods are used, such as welding and threaded connections, to ensure airtightness. Insulation measures are taken to reduce heat loss. Their rational layout and design significantly impact heating efficiency and energy consumption, ensuring indoor warmth and comfort. To extend the service life of heating pipes, protective structures are generally added to the connection points.

[0003] Chinese Patent No. CN221483029U discloses a heating pipeline protection device, including a placement seat. The number of placement seats is two and they are arranged symmetrically on the left and right. The upper surface of each of the two placement seats is provided with a fixing ring. The lower surface of each fixing ring is fixedly connected with a locking block at the front and rear positions. The upper surface of each placement seat is provided with a locking groove that engages with the locking block. Multiple support rods are provided between the two placement seats and the two fixing rings. Both the placement seats and the fixing rings are provided with slots for inserting the support rods.

[0004] However, the above structure still has some shortcomings. When adding a protective structure to the heating pipe, since the protective structure is usually fixed, once the position is installed, the length of the protective structure cannot be adjusted. Since the length requirements of different heating pipes are different, this will reduce the safety protection of the heating pipe and also make it difficult for users to inspect or maintain the heating pipe later.

At the same time, the user can also directly pull out the sleeve plate through the sleeve principle to inspect or maintain the connection points of the first pipe body.

[0016] Secondly, due to the presence of the first locking block, the second locking block can be inserted into the circular groove. By adjusting the second locking block to an angle that does not correspond to the second locking groove, the second locking block can be engaged in the circular groove to limit the position of the second docking valve. The retaining spring can engage the position of the second locking block a second time, thereby effectively improving the stability of the second locking block's engagement and the stability of the second docking valve's installation. When the second docking valve needs to be disassembled later, the second locking block can be adjusted to an angle that corresponds to the second locking groove, and then the first locking block can be pulled out directly. This facilitates the disassembly and assembly of the second docking valve and also makes it easier for users to perform separate maintenance on the first or second pipe body.

[0025] Example

[0026] refer to Figures 1 to 7 This embodiment of a heating pipe protection device includes a first pipe body 1. A first docking valve 15 is fixedly connected to one side of the first pipe body 1. A second docking valve 16 is snapped onto one side of the first docking valve 15. A second pipe body 2 is fixedly connected to one side of the second docking valve 16. A first reinforcing frame 5 is provided on the outer side of the first pipe body 1, and a second reinforcing frame 6 is provided on the outer side of the second pipe body 2. Support blocks 3 are fixedly connected to the bottom ends of both the first reinforcing frame 5 and the second reinforcing frame 6. A sleeve plate 7 is fixedly connected to one side of the first reinforcing frame 5, and a movable plate 8 is fixedly connected to the other side of the second reinforcing frame 6. The movable plate 8 is sleeved inside the sleeve plate 7. A second screw hole 11 is opened at the top of the second reinforcing frame 6. The side threaded connection has a second bolt 12, the top of which corresponds to the top of the second pipe body 2. In use, the first reinforcing frame 5 and the second reinforcing frame 6 can provide good reinforcement. The movable plate 8 and the sleeve plate 7 can also effectively protect the connection point of the first pipe body 1, thereby improving the safety of the connection between the first pipe body 1 and the second pipe body 2. When it is necessary to adjust the length of the protective structure, the user can directly pull the second reinforcing frame 6 through the sleeve principle, and its movable plate 8 will be extended accordingly. After the length adjustment is completed, the second bolt 12 is turned and placed on the top of the second pipe body 2 to limit the position of the second reinforcing frame 6, thereby achieving the effect of conveniently adjusting the length of the protective structure.

[0027] refer to Figures 1 to 3The top of the first reinforcing frame 5 is provided with a first screw hole 9, which extends into the interior of the first tube 1. The inner side of the first screw hole 9 is threaded with a first bolt 10, and the bottom end of the first bolt 10 is threaded into the interior of the first tube 1 through the first screw hole 9. The top of the support block 3 is provided with a positioning hole 4, which penetrates the support block 3. Due to the presence of the first bolt 10, the screwing in of the first bolt 10 can effectively limit the position of the first reinforcing frame 5 to prevent the first reinforcing frame 5 from shifting. When the first reinforcing frame 5 needs to be disassembled later, the first bolt 10 can be unscrewed. It also facilitates the user to maintain the structure on the first reinforcing frame 5 later.

[0028] refer to Figures 1 to 3 The top end of the second tube 2 is provided with a groove 13. An anti-slip pad 14 is fixedly connected to the inner side of the groove 13. The anti-slip pad 14 covers the inner side of the groove 13. The top end of the anti-slip pad 14 is in contact with the bottom end of the second bolt 12. Due to the presence of the anti-slip pad 14, the anti-slip pad 14 can increase the friction on the inner side of the groove 13, thereby effectively improving the stability of the second bolt 12's position pressing, and also preventing the second bolt 12 and the second tube 2 from colliding with each other.

[0029] refer to Figures 4 to 7A first slot 17 is provided on the other side of the first docking valve 15, extending into the interior of the second docking valve 16. A second slot 18 is provided on the inner wall of the first slot 17, and a circular groove 19 is provided on the inner side of the first slot 17. A first locking block 23 is engaged with the inner side of the first slot 17. A second locking block 24 matching the second slot 18 is fixedly connected to the outer side of the first locking block 23, and the second locking block 24 is engaged with the inner side of the circular groove 19. A retaining spring 20 matching the second locking block 24 is installed on the inner side of the circular groove 19, and one side of the second locking block 24 is engaged with the other side of the retaining spring 20. The second locking block 24 is engaged with the inner side of the circular groove 19 through the retaining spring 20. A sealing block 25 is fixedly connected to the other side of the first locking block 23, covering one side of the first slot 17. A protrusion 26 is fixedly connected to the other side of the sealing block 25, and the protrusion 26 has corners. The shape is arc-shaped. Due to the presence of the first locking block 23, the second locking block 24 can be sent into the circular groove 19. The second locking block 24 is adjusted to a non-corresponding angle with the second locking groove 18, so that the second locking block 24 can be locked in the circular groove 19 to limit the position of the second docking valve 16. The retaining spring 20 can lock the position of the second locking block 24 for a second time, thereby effectively improving the stability of the locking position of the second locking block 24 and also effectively improving the stability of the installation of the second docking valve 16. When the second docking valve 16 needs to be disassembled later, the second locking block 24 is adjusted to a corresponding angle with the second locking groove 18, and then the first locking block 23 can be directly pulled out. This can facilitate the disassembly and assembly of the second docking valve 16 later, and also make it easier for users to perform individual maintenance on the first pipe body 1 or the second pipe body 2 later.

[0030] refer to Figures 4 to 7 A positioning groove 21 is provided on the other side of the second docking valve 16. The positioning groove 21 is located on the four sides near the corner of the other side of the second docking valve 16. A positioning block 27 matching the positioning groove 21 is fixedly connected to one side of the first docking valve 15. The positioning block 27 is engaged inside the positioning groove 21. Due to the presence of the positioning block 27, the engagement of the positioning block 27 can limit the position of the second docking valve 16 in advance. While improving the engagement stability of the second docking valve 16, it also effectively improves the engagement accuracy of the first locking block 23.

[0031] refer to Figures 4 to 7 The other side of the second docking valve 16 is provided with a sealing groove 22. A sealing ring 28 that matches the sealing groove 22 is fixedly connected to one side of the first docking valve 15. The sealing ring 28 is located on the inner side close to the first locking block 23. The sealing ring 28 covers the inner side of the sealing groove 22. Due to the presence of the sealing ring 28, the sealing ring 28 can effectively seal the connection point of the first docking valve 15, thereby achieving a good dustproof sealing effect.

[0032] Operating principle and advantages: During use, the first reinforcing frame 5 and the second reinforcing frame 6 provide good reinforcement. The movable plate 8 and the sleeve plate 7 also effectively protect the connection point of the first pipe body 1, thereby improving the safety of the connection between the first pipe body 1 and the second pipe body 2. When it is necessary to adjust the length of the protective structure, the user can directly pull the second reinforcing frame 6 through the sleeve principle, and its movable plate 8 will be extended accordingly. After the length adjustment is completed, tightening the second bolt 12 and pressing it against the top of the second pipe body 2 will limit the position of the second reinforcing frame 6, thus achieving convenient adjustment of the protective structure. The length effect, due to the presence of the first bolt 10, effectively limits the position of the first reinforcing frame 5 when screwed in, preventing displacement of the first reinforcing frame 5. When the first reinforcing frame 5 needs to be disassembled later, the first bolt 10 can be unscrewed. This also facilitates later maintenance of the structure on the first reinforcing frame 5. Due to the presence of the anti-slip pad 14, the friction inside the groove 13 is increased, effectively improving the stability of the pressure on the position of the second bolt 12. It also prevents the second bolt 12 from colliding with the second pipe body 2. Due to the first locking block 23... The second locking block 24 is present, allowing it to be inserted into the circular groove 19. Adjusting the second locking block 24 to a position that does not correspond to the second locking groove 18 allows it to engage within the circular groove 19, thus limiting the position of the second docking valve 16. The retaining spring 20 provides secondary engagement of the second locking block 24, effectively improving the stability of the engagement and the overall stability of the second docking valve 16 installation. When the second docking valve 16 needs to be disassembled later, the second locking block 24 is adjusted to a position corresponding to the second locking groove 18. Then, the first locking block 23 can be directly pulled out, which facilitates the later disassembly and assembly of the second docking valve 16. It also makes it easier for users to perform separate maintenance on the first pipe body 1 or the second pipe body 2. Due to the presence of the sealing ring 28, the sealing ring 28 can effectively seal the connection point of the first docking valve 15, thus achieving a good dustproof sealing effect. Due to the presence of the positioning block 27, the insertion of the positioning block 27 can pre-limit the position of the second docking valve 16, which not only improves the stability of the second docking valve 16's position but also effectively improves the accuracy of the first locking block 23's insertion.
