[0003] Currently, most existing LED energy-saving fluorescent tubes use an integrated fixed PCB board structure. This typically involves fixing the entire PCB board to a support structure inside the tube. All components are integrated on the PCB board, and power is supplied via an external circuit to the LED chips inside the tube to provide illumination. However, this existing structure has significant shortcomings. Because the PCB board is a fixed, integrated design without a detachable connection structure, when some components on the PCB board malfunction and require repair or replacement, or when the component layout needs to be adjusted according to usage requirements, the entire PCB board must be removed from the tube, sometimes even requiring disassembly of the tube itself. This cumbersome and complex operation not only increases the workload of repair and adjustment, reduces work efficiency, but also easily damages the PCB board or the internal structure of the tube during disassembly, affecting the normal use of the tube.

[0010] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figure 1 and 9The diagram shows an embodiment of an LED energy-saving fluorescent tube with an adjustable structure combining a PCB board and components provided by the present invention. It includes a main body 1, which serves as the carrier of the LED energy-saving fluorescent tube, providing the installation and support foundation for all structures within the device, ensuring the integrity and stability of the overall structure, and protecting internal components from damage caused by the external environment. The LED chip board 9 is used to install LED chips, receive power from external circuits, and achieve illumination. It provides stable and efficient lighting support for various application scenarios and is the core component for the LED energy-saving fluorescent tube to achieve its lighting function.
[0011] The LED chip board 9 has a transmission plate 10 inside to connect the LED chip board 9 to the main board 11, ensuring smooth signal and power transmission between them. This ensures the LED chip board 9 can receive power and emit light normally. The transmission plate 10 also helps to fix the position of the main board 11. The top of the transmission plate 10 is fixedly connected to the main board 11, which serves as the core of the PCB board, carrying the main circuit components and implementing circuit control and signal transmission functions. It provides a connection base for the sub-board 12, ensuring the stable operation of the entire PCB board circuit. The main board 11 and sub-board 12 assist the main board 11 in carrying components, expanding the component installation range of the PCB board and facilitating the layout of different components according to usage requirements. They can also be disassembled individually for easy inspection, replacement, and adjustment of the components. The fixed long plate 5 provides a flat laying carrier for the main board 11 and the sub-board 12, and plays a supporting and limiting role for the main board 11 and the sub-board 12, ensuring that the main board 11 and the sub-board 12 can be installed stably, ensuring the installation stability of the PCB board and components, and at the same time assisting in the stable transmission of the circuit. The fixed square plate 24 carries the bolts 25, and together with the elastic disc 23, it plays a pressing and fixing role for the sealing plate 22, ensuring that the sealing plate 22 can be stably installed at the top of the device body 1, preventing the sealing plate 22 from loosening and falling off, and ensuring the sealing of the device. The sealing plate 22 plays a sealing and protective role for the top of the device body 1, preventing external dust and moisture from entering the device and damaging the internal structure. At the same time, it plays a limiting role for the U-shaped block 8, strengthening the installation stability of the main board 11 and the sub-board 12.
[0012] The main board 11 has two internal sliding connection plates 13 to achieve the sliding connection between the main board 11 and the sub-board 12, providing guidance for the disassembly and installation of the sub-board 12, ensuring that the sub-board 12 can accurately mate with the main board 11, and ensuring the stability of the circuit connection between the main board 11 and the sub-board 12. The sub-board 12 is externally fixedly connected to the transfer plate 13. The sub-board 12 has two fixed round rods 14 externally fixedly connected to it, which play an auxiliary role in fixing the sub-board 12, enhancing the installation stability of the sub-board 12, preventing the sub-board 12 from shaking or loosening during use, and ensuring the normal operation of the components on the sub-board 12. The bottom ends of the sub-board 12 and the main board 11 are both fixedly connected to U-shaped blocks 8, which provide a mounting carrier for the sliding block 15, sliding block 2 16, limit rod 18 and spring 19, forming a limit fixing structure, which plays a limiting role for the main board 11 and the sub-board 12.
[0013] To ensure stability after the main board 11 and the sub-board 12 are connected, the U-shaped block 8 has multiple sliding blocks 15 inside, which work with sliding blocks 2 16 and the top round rod 17 to achieve a limiting and fixing function, helping to fix the relative position of the main board 11 and the sub-board 12 and prevent them from separating or loosening during use. The bottom end of sliding block 15 is slidably connected to sliding block 2 16, which works with sliding block 15, the top round rod 17, the limiting rod 18, and the spring 19 to achieve the limiting and unlocking functions of the main board 11 and the sub-board 12, providing support for the disassembly and installation of the sub-board 12 and ensuring ease of operation. The outside of sliding block 2 16 is slidably connected to the inside of the U-shaped block 8, and the top round rod 17 is inserted into the inside of sliding block 1 15 to achieve a fixed docking between sliding block 1 15 and sliding block 2 16, strengthening the limiting function. The effect is to prevent displacement of sliding block 15, ensuring the stability of the connection between the main board 11 and the sub-board 12. Sliding block 26 is externally fixedly connected to a top round rod 17. Sliding block 26 is externally fixedly connected to a limit rod 18, which guides and limits the spring 19, preventing the spring 19 from shifting or twisting during extension and retraction, ensuring that the spring 19 can stably exert its elastic function, and at the same time assisting sliding block 26 to achieve smooth sliding. The limit rod 18 is externally slidably connected to the inside of the U-shaped block 8, and the sealing plate 22 is externally slidably connected to the inside of the U-shaped block 8. The spring 19, which is externally sleeved on the limit rod 18, provides the reset force for sliding block 26 through its own elastic deformation, ensuring that sliding block 26 can stably engage sliding block 15, achieving stable limiting between the main board 11 and the sub-board 12, and facilitating unlocking operation.
[0014] One end of the spring 19 is fixedly connected to the outside of the sliding block 16, and the other end of the spring 19 is fixedly connected to the inside of the U-shaped block 8. A sliding round rod 20 is fixedly connected to the outside of the sliding block 16 inside the sub-plate 12, connecting the contact disc 21 and the sliding block 16, providing a transmission function for the sliding of the sliding block 16. It is convenient to control the position of the sliding block 16 by operating the contact disc 21, so as to unlock and fix the sub-plate 12. The contact disc 21 is fixedly connected to the outside of the sliding round rod 20 to provide an operating grip for the operator, so that the operator can pull the sliding round rod 20 to control the sliding of the sliding block 16, realize the disassembly and installation of the sub-plate 12, and improve the convenience of operation.
[0015] The main body 1 of the device has two rotating disks 2 internally connected to provide a carrier for the sliding installation of contact blocks 3. These disks assist in the position adjustment of contact blocks 3, ensuring stable connection to external circuits and smooth power transmission. Simultaneously, they work with limiting disks 4 to limit and fix the overall structure. The contact blocks 3, slidably connected internally to the rotating disks 2, serve as a connection medium between the external circuits and the internal components of the device, enabling the transmission of external power to the internal components. This provides stable power support for components such as the LED chip board 9, ensuring the normal operation of the LED energy-saving fluorescent tubes. The limiting disks 4 externally fix the contact blocks 3, fixing and limiting the fixed long plate 5, ensuring its stable installation in the designated position, and simultaneously connecting with the light-transmitting cover. The two limiting discs 4 are coordinated to form a protective space for the LED board 9, preventing it from being damaged by external impacts or dust contamination. Two fixed long plates 5 are fixedly connected to the adjacent ends of the two limiting discs 4. The fixed long plates 5 are fixedly connected to the internal limiting long plates 6 to further enhance the limiting effect of the fixed long plates 5 on the main board 11 and the sub-board 12, preventing the main board 11 and the sub-board 12 from shifting or sliding during use, ensuring the installation accuracy of the main board 11 and the sub-board 12, and ensuring the stability of circuit transmission. The two limiting discs 4 are fixedly connected to the external light-transmitting cover 7 to protect the LED board 9 from damage by external dust, moisture or impacts. At the same time, it can make the light emitted by the LED board 9 pass through evenly, ensuring the uniformity of the lighting effect and improving the lighting experience.
[0016] The top of the main body 1 is provided with a sealing plate 22. A reflector 26 is fixedly connected to the outside of the main body 1 to reflect the light emitted by the LED bead plate 9, thereby improving the light utilization rate and enhancing the lighting brightness and effect of the LED energy-saving fluorescent tube. Two sliding grooves are opened on the outside of the main body 1. Two elastic discs 23 are provided on the outside of the two sliding grooves to fix the sealing plate 22 in conjunction with the fixing square plate 24 and bolts 25. The elastic discs 23 fit into the sliding grooves of the main body 1 by their own elastic deformation, which enhances the tightness of the fixation and facilitates disassembly. The top of the elastic disc 23 is fixedly connected to the fixing square plate 24. Bolts 25 are slidably connected between the elastic disc 23 and the fixing square plate 24 to limit and fix the fixing square plate 24 and the elastic disc 23. Fixing and unlocking are achieved by rotation, which facilitates the disassembly and installation of the sealing plate 22 and ensures the convenience of operation and the reliability of fixation.
[0017] Working principle: The main body 1 of the device serves as the main support for the LED energy-saving fluorescent tube. It has two rotating discs 2 inside, and a contact block 3 is slidably connected inside the rotating disc 2. A limiting disc 4 is fixedly connected to the outside of the contact block 3. Two fixed long plates 5 are fixedly connected to the near ends of the two limiting discs 4. A limiting long plate 6 is fixedly connected inside the fixed long plate 5. A light-transmitting cover 7 is fixedly connected to the outside of the two limiting discs 4. The main plate 11 and the sub-plate 12 are laid flat on the outside of the fixed long plate 5. The lamp bead plate 9 is installed inside the light-transmitting cover 7.
[0018] The LED bead board 9 has a transfer plate 10 inside. A main board 11 is fixedly connected to the top of the transfer plate 10. Two transfer plates 13 are slidably connected inside the main board 11. A secondary plate 12 is fixedly connected to the outside of the transfer plate 13. Two fixed round rods 14 are fixedly connected to the outside of the secondary plate 12. U-shaped blocks 8 are fixedly connected to the bottom ends of both the secondary plate 12 and the main board 11. Multiple sliding blocks 15 are slidably connected inside the U-shaped blocks 8. A second sliding block 16 is slidably connected to the bottom end of the first sliding block 15. A top round rod 17 is fixedly connected to the outside of the second sliding block 16. A limit rod 18 is fixedly connected to the outside of the second sliding block 16. A spring 19 is sleeved on the outside of the limit rod 18. One end of the spring 19 is fixedly connected to the outside of the second sliding block 16, and the other end is fixedly connected to the inside of the U-shaped block 8. The external sliding connection is to the inside of the U-shaped block 8. The external sliding block 26 is to the inside of the U-shaped block 8. The external sliding connection of the top round rod 17 is to the inside of the U-shaped block 8. The external sliding block 26 inside the sub-plate 12 is fixedly connected to the external sliding round rod 20. The external contact disc 21 is fixedly connected to the external sliding round rod 20. The top of the device body 1 is provided with a sealing plate 22. The external sealing plate 22 is to the inside of the U-shaped block 8. The external reflector 26 is fixedly connected to the external of the device body 1. Two sliding grooves are opened on the external of the device body 1. Two elastic discs 23 are provided on the external of the two sliding grooves. The top of the elastic discs 23 is fixedly connected to a fixed square plate 24. The external of the fixed square plate 24 is in contact with the top of the sealing plate 22. The elastic discs 23 and the internal of the fixed square plate 24 are slidably connected by bolts 25.
[0019] When it is necessary to adjust or disassemble the PCB board and components inside the LED energy-saving fluorescent tube, first rotate the bolt 25 to release the limiting effect of the bolt 25 on the fixed square plate 24 and the elastic disc 23. Then pull the fixed square plate 24 upward to make the fixed square plate 24 drive the elastic disc 23 to disengage from the sliding groove opened on the outside of the device body 1, thereby releasing the limiting effect of the fixed square plate 24 on the sealing plate 22. Then pull the sealing plate 22 upward to make the sealing plate 22 be pulled out from the top of the device body 1, thereby releasing the limiting effect of the sealing plate 22 on the U-shaped block 8. At this time, the main board 11 and the sub-board 12 can be operated.
[0020] When it is necessary to remove the sub-board 12 from the main board 11, first pull the contact disc 21 on the outside of the sub-board 12. The contact disc 21 drives the sliding rod 20 to move. The sliding rod 20 drives the sliding block 16 inside the sub-board 12 to slide inside the U-shaped block 8. During the sliding process, the sliding block 16 drives the limiting rod 18 to move synchronously. The limiting rod 18 compresses the spring 19, causing the spring 19 to undergo elastic deformation. At the same time, the sliding block 16 drives the top rod 17 to move, causing the top rod 17 to disengage. Inside the sliding block 15, the limiting action of the sliding block 16 on the sliding block 15 is released. Then, the sub-board 12 is pulled, and the sub-board 12 drives the transfer plate 13 to slide inside the main board 11. At the same time, the sub-board 12 drives the U-shaped block 8 to move, so that the U-shaped block 8 drives the sliding block 15 to move until the transfer plate 13 is completely pulled out from inside the main board 11. This completes the separation of the sub-board 12 from the main board 11, enabling the quick disassembly of the sub-board 12 and facilitating the inspection, replacement, or adjustment of the components on the sub-board 12.
[0021] When the sub-board 12 needs to be installed onto the main board 11, first align the transfer plate 13 on the outside of the sub-board 12 with the sliding groove inside the main board 11, then push the sub-board 12 so that the transfer plate 13 slides inside the main board 11 until the transfer plate 13 is completely slid into the interior of the main board 11. At this time, the sub-board 12 drives the U-shaped block 8 to move, and the U-shaped block 8 drives the sliding block 15 to move. When the sliding block 15 moves to the designated position, release the contact disc 21, and the elastic potential energy of the spring 19 is released, pushing the sliding block 26 to slide in the opposite direction inside the U-shaped block 8. The sliding block 26 drives the top rod 17 to move, so that the top rod 17 is inserted into the interior of the sliding block 15, limiting the sliding block 15, thereby completing the fixation of the sub-board 12 and the main board 11, realizing the rapid installation of the sub-board 12.
[0022] After the main board 11 and the sub-board 12 are installed, the sealing plate 22 is inserted into the top of the main body 1 of the device, so that the sealing plate 22 slides into the interior of the U-shaped block 8 and limits the U-shaped block 8. Then, the elastic disc 23 is inserted into the sliding groove opened on the outside of the main body 1 of the device, so that the outside of the fixed square plate 24 contacts the top of the sealing plate 22. Then, the bolt 25 is rotated so that the bolt 25 limits the fixed square plate 24 and the elastic disc 23, thus completing the fixing of the sealing plate 22. At this time, the main board 11 and the sub-board 12 inside the main body 1 of the device are limited by the fixed long plate 5 and the limiting long plate 6. The light-transmitting cover 7 protects the LED bead plate 9, and the reflector 26 reflects the light emitted by the LED beads, improving the lighting effect of the LED energy-saving fluorescent tube. The contact block 3 is connected to the external circuit to provide power to the LED energy-saving fluorescent tube, so that the LED energy-saving fluorescent tube can work normally.
[0023] When it is necessary to adjust the components on the main board 11, the main board 11 can be pulled directly, causing the main board 11 to move the U-shaped block 8. The U-shaped block 8 then moves the sliding block 15 and the sliding block 16 until the main board 11 is pulled out from the outside of the fixed long plate 5. The components on the main board 11 can then be inspected, replaced, or adjusted. After the adjustment is completed, the main board 11 is reinstalled to the outside of the fixed long plate 5 to reset the main board 11. The entire operation does not require disassembly of the main body 1 of the device, making the operation convenient and improving the efficiency of PCB board and component adjustment.
[0024] When the LED energy-saving fluorescent tube is working normally, the external circuit provides power to the LED bead board 9 through the contact block 3. The LED beads on the LED bead board 9 emit light, and the light shines outward through the light-transmitting cover 7. At the same time, the reflector 26 reflects the light, improving the utilization rate of the light. The main board 11 and the sub-board 12 are connected to the U-shaped block 8 through the transmission plate 13 to ensure stable circuit transmission. The spring 19 limits the sliding block 15 through the sliding block 2 16 and the top round rod 17 to prevent the main board 11 and the sub-board 12 from becoming loose during use, thus ensuring the stable operation of the LED energy-saving fluorescent tube.
