Detailed Implementation
[0022] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0023] Reference Figure 1 and Figure 2This utility model describes a pipe repair lamp holder structure for easy replacement of ultraviolet lamps. The main structure includes multiple lamp holder bodies 1, each a cylindrical frame structure used to support ultraviolet lamps 5. Cables 2 connect adjacent lamp holder bodies 1. Specifically, connection ports for electrical connection to multiple ultraviolet lamps 5 are provided on the lamp holder bodies 1. The connection ports on two lamp holder bodies 1 are connected by cables 2, thereby achieving electrical connection of the ultraviolet lamps 5 on multiple lamp holder bodies 1 and ensuring power supply to the ultraviolet lamps 5 on multiple lamp holder bodies 1. A lamp groove 3 is provided inside the lamp holder body 1, recessed inward from the surface of the lamp holder body 1. Multiple lamp ports 4 are fixed in the lamp groove 3 by welding or bolts, and the lamp ports 4 are electrically connected to the cables 2. A UV lamp 5 is movably connected to the port 4. The UV lamp 5 can use existing UV lamp structures for photocuring repair, typically mercury lamps or LED lamps. The UV lamps 5 are arranged in a circular array inside the lamp trough 3. Specifically, the UV lamps 5 are threaded or movably plugged into the port 4, allowing for convenient installation and removal. A lamp cover 6 is rotatably fitted onto the outside of the lamp trough 3. The lamp cover 6 is a ring-shaped plate structure that rotatably fits onto the outside of the lamp trough 3 to protect the UV lamps 5 inside. Multiple limiting rods 7 are provided between the lamp cover 6 and the lamp holder body 1. After the lamp cover 6 rotates, the limiting rods 7 limit its position, preventing further rotation and ensuring the stability of the lamp cover 6 during use, thus guaranteeing the photocuring effect. The lamp cover 6 is equipped with a detection... The access port 8 penetrates the lamp cover 6. The access port 8 is larger than the UV lamp 5, allowing operators to easily access and replace the UV lamp 5. A cover plate 9 is slidably connected to the access port 8, controlling its opening and closing. Both the lamp cover 6 and the cover plate 9 have multiple light-transmitting holes 10. These holes effectively protect the UV lamp 5 without obstructing its light emission. A positioning post 11 is provided between the cover plate 9 and the lamp cover 6. This post fixes the cover plate 9 in place after it slides to close the access port 8, ensuring its structural integrity. This design allows for easy replacement of the UV lamp 5 at a specific location. First, release the restriction of the positioning post 11, slide the cover plate 9 to open the inspection port 8, then release the restriction of the limiting rod 7 and rotate the lamp cover 6 so that the inspection port 8 on the lamp cover 6 is rotated to the position of the UV lamp 5 that needs to be replaced. After that, the operator can put his hand through the inspection port 8 and remove the faulty UV lamp 5 for replacement. By rotating the lamp cover 6, the UV lamp 5 in any position can be replaced without disassembling the lamp cover 6 and other protective structures. The maintenance process will not damage the UV lamps 5 in other positions, which greatly improves the convenience of replacing the UV lamp 5. A circular plate 12 is slidably connected to one side of the lamp holder body 1 along the lateral direction. The circular plate 12 slides along the axial direction of the lamp holder body 1. A scissor-type telescopic rod 13 is provided between the circular plate 12 and the lamp holder body 1.Specifically, the scissor-type telescopic rod 13 is a scissor-type telescopic structure, consisting of two connecting rods hinged in the middle. The ends of the two connecting rods are respectively hinged to the lamp holder body 1 and the circular plate 12. The ends of the scissor-type telescopic rod 13 are equipped with rollers 14, which are rotatably connected to the ends of the two connecting rods. The lamp holder body 1 is equipped with an adjusting rod 15 that drives the circular plate 12 to slide laterally. This structure allows the scissor-type telescopic rod 13 to extend and retract when the position of the circular plate 12 is adjusted using the adjusting rod 15, thereby changing the height of the rollers 14 at the ends. This accommodates the repair needs of pipes of different sizes. Multiple scissor-type telescopic rods 13 are used, and after extension and retraction, they surround the outside of the lamp holder body 1, also providing protection for the ultraviolet lamps 5. Furthermore, the scissor-type telescopic rods 13 are positioned outside the positions between adjacent ultraviolet lamps 5. This structure ensures that the scissor-type telescopic rods 13 do not interfere with the replacement of the ultraviolet lamps 5, further guaranteeing the convenience of ultraviolet lamp replacement.
[0024] Preferred, refer to Figure 3 and Figure 5 Both sides of the access port 8 are fixed with fixing plates 16 by welding or bolts. The cover plate 9 passes through one of the fixing plates 16 and is slidably connected to it. Specifically, a through sliding hole is provided on one of the fixing plates 16, and the cover plate 9 passes through the sliding hole and is slidably connected to it. The positioning post 11 is set between the cover plate 9 and the fixing plate 16 on the other side. This structure allows the cover plate 9 to slide relative to one of the fixing plates 16 when it slides, ensuring the stability of the sliding structure of the cover plate 9. When the access port 8 is closed by sliding, one end of the cover plate 9 is fixed to the fixing plate 16 on the other side by the positioning post 11, so that the cover plate 9 is firmly fixed at the access port 8, improving the firmness of the cover plate 9 in controlling the opening and closing of the access port 8.
[0025] Preferably, one side of the cover plate 9 is fixed with an end plate 17 by welding or integral molding. The positioning post 11 passes through the fixing plate 16 and is threadedly connected to the end plate 17. With this structure, the end of the positioning post 11 can pass through the fixing plate 16 and be threadedly connected to the end plate 17 simply by rotating the positioning post 11, thereby preventing the cover plate 9 from continuing to slide. This makes the fixing operation of the cover plate 9 more convenient and improves the convenience and firmness of fixing the cover plate 9.
[0026] Preferred, refer to Figure 4 The lamp slot 3 has symmetrical ring plates 18 fixed on both sides by welding or bolts. The lamp cover 6 is rotatably sleeved on the outside of the ring plates 18. The ring plates 18 on both sides can provide support for the lamp cover 6, so that the lamp cover 6 rotates around the outside of the ring plates 18 when it rotates, which further improves the robustness of the rotating structure of the lamp cover 6.
[0027] Preferably, the lampshade 6 is fixed with multiple fixing blocks 19 by welding or bolts. Each fixing block 19 has multiple through round holes. The limiting rod 7 passes through the multiple fixing blocks 19 and is threadedly connected to the lamp holder body 1. This structure only requires the limiting rod 7 to pass through one side of the lamp holder body 1, then align it with the round holes of the multiple fixing blocks 19 on the lampshade 6, and then pass the limiting rod 7 through the round holes. Subsequently, the end of the limiting rod 7 is threadedly connected to the other side of the lamp holder body 1. Thus, with the cooperation of the multiple fixing blocks 19, the position of the lampshade 6 is fixed, preventing the lampshade 6 from continuing to rotate, making the restriction of the position of the lampshade 6 simpler and more stable.
[0028] Preferably, a fixed shaft 20 is fixed to one side of the lamp holder body 1 by welding or bolts, and the circular plate 12 is slidably sleeved on the outside of the fixed shaft 20. The fixed shaft 20 provides sliding support for the circular plate 12, so that the circular plate 12 can move along the axial direction of the fixed shaft 20, which improves the stability of the sliding structure of the circular plate 12 and ensures the stability of the scissor telescopic rod 13 structure between the circular plate 12 and the lamp holder body 1.
[0029] Preferably, the adjusting rod 15 is rotatably connected to the side of the lamp holder body 1 via a bearing. The adjusting rod 15 passes through the circular plate 12 and is threadedly connected to it. When the adjusting rod 15 rotates, the circular plate 12 is driven to slide along the fixed shaft 20 under the action of the threaded connection. A guide rod 21 is fixed to one side of the lamp holder body 1 by welding or bolts. The guide rod 21 passes through the circular plate 12 and is slidably connected to it. The setting of the guide rod 21 can further improve the restriction effect on the sliding structure of the circular plate 12, making the circular plate 12 less prone to tilting or shaking, and further improving the firmness of the sliding structure of the circular plate 12. Specifically, a fixing bolt is threadedly connected to the edge of the circular plate 12. After the fixing bolt passes through the circular plate 12, it contacts the surface of the fixed shaft 20. In this way, after the circular plate 12 slides, the fixing bolt is used to lock and fix the position of the circular plate 12, further improving the firmness of the position of the circular plate 12 and providing effective support and limitation for the structure of the scissor telescopic rod 13 after extension and retraction.
[0030] Working Principle: This invention features a lampshade 6 rotatably mounted on the lamp slot 3 of the lamp holder body 1. The lampshade 6 has an inspection port 8, and a cover plate 9 is slidably connected to the inspection port 8. When replacing a UV lamp 5, simply release the positioning post 11 from the cover plate 9, then slide the cover plate 9 to open the inspection port 8. Next, release the limiting rod 7 from the lampshade 6, rotate the lampshade 6 so that the inspection port 8 is positioned to replace the UV lamp 5. By hand passing through the inspection port 8, the lampshade 6 on the lamp opening 4 can be removed for replacement. This allows for the replacement of any UV lamp 5 on the lamp holder body 1 without disassembling the lampshade 6, greatly simplifying the replacement process. The replacement process does not damage other UV lamps 5, significantly improving the efficiency of UV lamp replacement. Convenience: A circular plate 12 is slidably connected to one side of the lamp holder body 1. A scissor-type telescopic rod 13 is provided between the circular plate 12 and the lamp holder body 1. The end of the scissor-type telescopic rod 13 is provided with a roller 14. This structure allows the position of the circular plate 12 to be slidably adjusted by the adjusting rod 15, thereby allowing the scissor-type telescopic rod 13 between the circular plate 12 and the lamp holder body 1 to extend and retract, causing the height of the roller 14 to change. This meets the needs of light curing repair for pipes of different diameters. After extension and retraction, the multiple scissor-type telescopic rods 13 surround the outside of the lamp holder body 1, which can also protect the ultraviolet lamp 5 to a certain extent. Moreover, the scissor-type telescopic rods 13 are located outside the position between two adjacent lamp ports 4, so they will not interfere with the replacement of the ultraviolet lamp 5 at the lamp port 4, ensuring the efficiency and convenience of replacing the ultraviolet lamp 5.
