[0002] Panel lights are widely used in offices, shopping malls, classrooms, and other places due to their advantages such as soft light, uniform illumination, and convenient installation. In existing technologies, the splicing structure of panel lights mostly uses bolt fastening, snap-fit, and other methods to connect adjacent light frames. Its core structure usually includes several light frames connected end to end, as well as a back panel and a light-transmitting panel set between the light frames.

[0003] However, existing splicing structures have many drawbacks: First, when using bolt fastening, tools such as screwdrivers are required, making the installation and disassembly process cumbersome and inefficient. Furthermore, exposed bolts can affect the overall aesthetics of the panel light, and they are prone to corrosion after long-term use, leading to difficulties in subsequent maintenance. Second, when using snap-fit ​​fastening, the connection strength of the snaps is limited, and they are prone to loosening due to vibration or other factors during transportation or use, affecting the stability of the splicing and consequently damaging the lighting effect.

[0004] Therefore, a panel light splicing structure is needed to improve the above-mentioned problems. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] like Figures 1 to 5 The present invention preferably provides a panel light splicing structure, including a plurality of light frames 1 connected end to end, a back plate 2 and a light-transmitting plate 3 disposed between the plurality of light frames 1, and a plurality of connecting components correspondingly connected between adjacent light frames 1; the connecting components include L-shaped connectors 4 and rotating components 5, the light frames 1 have cavities 6 inside, and connecting holes 7 communicating with the cavities 6 are respectively opened at both ends of the upper side of the light frames 1, the L-shaped connectors 4 are respectively provided with connecting shafts 8 at both ends, and the connecting shafts 8 are respectively fitted into the connecting holes 7 of adjacent light frames 1 to connect the adjacent light frames 1; there are two rotating components 5, which are rotatably disposed on the connecting shafts 8, and can pass through the connecting holes 7 with the connecting shafts 8, and can rotate relative to the connecting shafts 8 to abut against the upper side of the cavity 6.

[0027] Specifically, the detachable connection of adjacent light frames is achieved through connecting components, while simultaneously assembling the back panel and the light-transmitting panel. The specific working process is as follows: First, several light frames are arranged in a preset splicing order, aligning the ends of adjacent light frames. Then, an L-shaped connector is taken, and its connecting shafts at both ends are aligned with the connecting holes opened at the upper ends of the adjacent light frames. At this time, the rotating parts are pre-rotated and set on the connecting shafts, and the rotating parts are in a position that can pass through the connecting holes with the connecting shafts. The connecting shafts are inserted into the connecting holes and extended into the cavities of the light frames, at which point the rotating parts are driven to simultaneously pass through the connecting holes and enter the cavities. Next, the two rotating parts are rotated relative to the connecting shafts, so that the rotating parts rotate from a position that can pass through the connecting holes to a position that abuts against the upper inner wall of the cavity. Through the abutment and limiting of the rotating parts against the upper side of the cavity, the connecting shafts can be prevented from coming out of the connecting holes, thereby achieving a stable connection between adjacent light frames. Finally, the back panel and the light-transmitting panel are respectively placed between several light frames, completing the basic assembly of the entire panel light splicing structure.

[0028] Furthermore, the connecting assembly also includes a locking member 9 that is connected to the rotating member 5 in a one-to-one manner. The locking member 9 can lock the rotating member 5 relative to the connecting shaft 8 so that the rotating member 5 is kept in a limited position within the cavity 6.

[0029] Specifically, once the rotating component reaches its limit position where it abuts against the upper side of the cavity, the locking component is operated to apply a locking force, restricting the rotational freedom of the rotating component relative to the connecting shaft. When it is necessary to disassemble or adjust the lamp frame, the locking component is released, allowing the rotating component to rotate again relative to the connecting shaft, returning to a position where it can pass through the connecting hole. This allows the connecting shaft to be pulled out of the connecting hole, achieving separation of adjacent lamp frames. The locking component ensures that the rotating component remains in a limited position during operation, preventing loosening due to external factors such as vibration, further improving connection stability.

[0030] Further, the locking member 9 comprises a pressing member 10 and a spring 11, a rotating shaft 12 extends from the upper end of the rotating member 5, the upper end of the rotating shaft 12 passes through the connecting shaft 8 and extends to the upper side of the L-shaped connecting member 4, a limiting guide groove 13 is recessed on the peripheral side of the rotating shaft 12 along the length direction thereof, the pressing member 10 is movably sleeved on the rotating shaft 12, and a flange 14 capable of cooperating with the limiting guide groove 13 is arranged on the inner side of the pressing member 10. The flange 14 cooperates with the limiting guide groove 13 to enable the pressing member 10 to displace up and down relative to the rotating shaft 12, and the pressing member 10 can drive the rotating shaft 12 to rotate. A limiting ring 15 is arranged on the L-shaped connecting member 4 above the pressing member 10, a plurality of clamping teeth 16 protruding outward are uniformly distributed on the inner side of the limiting ring 15 along the circumference, the cross-sectional outer shape of the pressing member 10 is arranged in a "convex" shape, the upper part of the pressing member 10 can extend and be accommodated in the inner ring of the limiting ring 15, a plurality of clamping grooves 17 capable of meshing with the clamping teeth 16 are recessed on the peripheral side of the upper part of the pressing member 10 along the circumference, the spring 11 is sleeved on the rotating shaft 12 with its two ends abutting between the L-shaped connecting member 4 and the pressing member 10, and the spring 11 keeps the clamping teeth 16 and the clamping grooves 17 in a meshed state.

[0031] Specifically, the locking and unlocking functions of the locking member are realized through the specific matching structure of the pressing member and the spring. The specific working process is as follows:

[0032] Locking process: The spring is sleeved on the rotating shaft, and its two ends abut against the L-shaped connecting member and the pressing member respectively. Under the elastic thrust of the spring, the pressing member is pushed upward, so that the upper part of the pressing member extends into the inner ring of the limiting ring, and the clamping teeth on the inner side of the limiting ring mesh with the clamping grooves on the peripheral side of the upper part of the pressing member; since the flange on the inner side of the pressing member cooperates with the limiting guide groove on the peripheral side of the rotating shaft, the pressing member cannot rotate relative to the rotating shaft, and then the rotation of the rotating shaft is restricted through the transmission action of the flange and the limiting guide groove, finally realizing the locking of the rotating member, so that the rotating member is kept in a limited state inside the cavity.

[0033] Unlocking process: Apply downward pressure to the pressing member to compress the spring, so that the pressing member displaces downward, driving the upper part of the pressing member to separate from the inner ring of the limiting ring, and at this time, the meshed state of the clamping teeth and the clamping grooves is released; subsequently, rotate the pressing member, and through the cooperation of the flange and the limiting guide groove, drive the rotating shaft to rotate synchronously, and then drive the rotating member to rotate, so that the rotating member is separated from the abutting state with the upper side of the cavity; release the pressing member, under the elastic force of the spring, the pressing member resets upward, but at this time the rotating member is already in a posture capable of passing through the connecting hole, and the unlocking is completed.

[0034] Further, a groove 18 is provided on one side of the connecting shaft 8 and located in the cavity 6, and the rotating member 5 is rotatably disposed in the groove 18 through the rotating shaft 12.

[0035] Specifically, the rotating component is rotatably mounted in the groove via a rotating shaft. The groove limits the rotation range of the rotating component, preventing it from shifting during rotation. Simultaneously, the groove protects the rotating component, preventing interference with other structures within the lamp frame cavity during operation, ensuring smooth rotation and improving the stability of the connecting assembly. Furthermore, the groove ensures more even force distribution when the rotating component abuts and is stopped, further enhancing the reliability of the connection between the connecting shaft and the lamp frame.

[0036] Furthermore, the inner side of the lamp frame 1 is recessed along its length direction with a first mounting groove 21 for placing the back plate 2.

[0037] Specifically, the size of the first mounting groove is adapted to the edge size of the back plate. After the connection of adjacent light frames is completed, the edge of the back plate is aligned with the first mounting groove inside several light frames, and the back plate is pushed in along the length of the first mounting groove so that the edge of the back plate is embedded in the first mounting groove. The first mounting groove limits the back plate, which can prevent the back plate from shifting during use and achieve stable assembly of the back plate. At the same time, no additional fixing parts are required, simplifying the assembly process.

[0038] Furthermore, the inner side of the lamp frame 1 is recessed along its length direction with a second mounting groove 22 for placing the light-transmitting plate 3.

[0039] Specifically, the dimensions of the second mounting groove are adapted to the edge dimensions of the light-transmitting plate. After the back panel is assembled, the edge of the light-transmitting plate is aligned with the second mounting groove inside several lamp frames, and the light-transmitting plate is pushed in along the length of the second mounting groove so that the edge of the light-transmitting plate is embedded in the second mounting groove. The second mounting groove not only limits and fixes the light-transmitting plate to prevent displacement, but also makes the light-transmitting plate and the lamp frame fit tightly, reducing gaps, improving lighting effect and overall aesthetics. It also simplifies the assembly process and improves assembly efficiency.

[0040] Furthermore, the joints of adjacent light frames 1 are set at a 45-degree angle.

[0041] Specifically, the ends of adjacent light frames are all machined into 45-degree bevels. When splicing, the two 45-degree bevels fit together to form a right-angle splicing structure. This splicing method can make the edges of adjacent light frames completely aligned, greatly reducing the splicing gap, achieving seamless splicing, and improving the uniformity of lighting. At the same time, the 45-degree angle fit can provide mutual positioning guidance for adjacent light frames, avoiding misalignment during splicing and improving the accuracy and efficiency of splicing.

[0042] Furthermore, the lamp frame 1 is a profile component.

[0043] Specifically, the components are manufactured through batch processing processes such as extrusion, which can precisely produce the cavities, connecting holes, first mounting slots, second mounting slots, and other structures required for the lamp frame, ensuring the consistency of the dimensions of each structure and facilitating the precise splicing of adjacent lamp frames and the fitting and installation of connecting components.
