[0037] The realization, functional features and advantages of the purpose of the present utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings. Specific embodiments

[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0039] In view of this, please refer to Figures 2 to 5, the present utility model provides a corner buckle device 100, which is suitable for being installed on the side of a cloth lamp 200 so that a support frame can support the cloth lamp 200 through the corner buckle device 100. The corner buckle device 100 includes a support member 110 and a pressing member 120. The support member 110 includes a first bracket and a second bracket integrally connected to the first bracket. The first bracket and the second bracket can be prepared by an integrally formed manufacturing method. In the related art, a first support block and a second support block with a split connection are usually arranged at the corners of the cloth lamp 200. The first support block and the second support block are respectively arranged on opposite sides of the cloth lamp 200. During the assembly process of the first support block, the second support block and the cloth lamp 200, it is necessary to position the first support block and the second support block one by one with the cloth lamp 200 and then fix them to the cloth lamp 200, which is cumbersome and the assembly efficiency of the cloth lamp 200 is low. In this application, the first bracket and the second bracket are integrally connected, eliminating the installation steps of frequently positioning the first support plate 111 and the second support plate 112 with the cloth lamp 200, effectively improving the assembly efficiency of the corner buckle device 100 and the cloth lamp 200, and at the same time improving the convenience of assembling the corner buckle device 100 and the cloth lamp 200. The first support plate 111 and the second support plate 112 are spaced apart from each other and jointly define a first accommodation space 130 capable of accommodating the side of the cloth lamp 200. The opening direction of the second accommodation space 1121 is the same as the opening direction of the first accommodation space 130. The second accommodation space 1121 is suitable for accommodating a support rod for supporting the cloth lamp 200. The first support plate 111 is provided with a mounting hole 1111, and the mounting hole 1111 penetrates through the first support plate 111 and the second support plate 112. The pressing member 120 is provided with a first connecting member 121, and the first connecting member 121 is configured to be able to pass through the mounting hole 1111 and be clamped to the second support plate 112. The setting of the pressing member 120 increases the contact area between the first support plate 111, the second support plate 112 and the cloth lamp 200 so as to stably clamp the cloth lamp 200. In the related art, holes are also drilled on the side of the cloth lamp 200 so that the support frame can support the cloth lamp 200. However, in order to facilitate drilling on the side of the cloth lamp 200, the width of the side of the cloth lamp 200 needs to be greater than the diameter of the hole, and the too wide side is likely to cause a reduction in the light-emitting area of the cloth lamp 200. In addition, the method of drilling holes on the side of the cloth lamp 200 is likely to cause a reduction in the structural strength of the cloth lamp 200. In this application, through the pressing member 120, the first support plate 111 and the second support plate 112 can press the cloth lamp 200, thereby reducing the drilling area on the side of the cloth lamp 200, and further reducing the setting area on the side of the cloth lamp 200, and further improving the light-emitting area of the cloth lamp 200. In addition, since the drilling area on the side of the cloth lamp 200 is reduced, the structural strength of the cloth lamp 200 is improved, effectively reducing the risk of damage to the cloth lamp 200 caused by too large a drilling area.

[0040] Please refer to Figure 5, the corner buckle device 100 further includes a second connecting member 140. When a corner of the light fixture 200 is inserted into the first accommodating space 130, the second connecting member 140 is configured to be connected to the first connecting member 121 so that the corner buckle device 100 is fixed to the light fixture 200. In some embodiments, the first connecting member 121 protrudes from the pressing member 120, and a countersunk hole is provided at one end of the first connecting member 121 away from the pressing member 120. The second connecting member 140 includes but is not limited to a pin, a threaded fastener (such as a bolt, a screw), etc. In a specific embodiment, the second connecting member 140 is configured to be inserted into the countersunk hole, so that the first support plate 111 and the second support plate 112 can fix the light fixture 200 under the action of the pressing member 120 and the second connecting member 140. When the side of the light fixture 200 is inserted into the first accommodating space 130 , the second connecting member 140 can be connected to the first connecting member 121 , thereby firmly fixing the corner buckle device 100 on the light fixture 200 , further enhancing the practicality and stability of the corner buckle device 100 .

[0041] In some embodiments, see Figure 4 The first support plate 111 is provided with a groove 1112, the mounting hole 1111 passes through the groove 1112, the pressing member 120 is configured to be able to buckle in the groove 1112, and the first connecting member 121 is inserted into the mounting hole 1111 through the groove 1112. By providing the groove 1112 on the first support plate 111 and passing the mounting hole 1111 through the groove 1112, the pressing member 120 can be more firmly buckled in the groove 1112, which not only increases the structural stability of the corner buckle device 100, but also makes it less likely to loosen or fall off during use. The design of the groove 1112 enables the first connecting member 121 to be inserted into the mounting hole 1111 more quickly and snap-fit ​​with the second support plate 112, which simplifies the installation process of the corner buckle device 100 and the light fixture 200, improves the installation efficiency, and also reduces the risk of damage to the light fixture 200 due to improper installation. In addition, due to the matching design of the groove 1112 and the mounting hole 1111, the corner buckle device 100 can adapt to different sizes and shapes of the light fixtures 200. Whether the light fixtures 200 are round, square or other irregular shapes, as long as the side of the light fixtures 200 can be inserted into the first accommodating space 130, the corner buckle device 100 can be applied.

[0042] To improve the connection stability between the corner buckle device 100 and the light fixture 200, please refer to Figure 5, a protrusion 122 is also provided on the side of the pressing member 120 close to the groove 1112, and a avoidance hole 113 is provided on the bottom wall of the groove 1112. When the pressing member 120 is clamped in the groove 1112, the protrusion 122 passes through the avoidance hole 113 and abuts against the cloth lamp 200. Among them, the direct contact between the protrusion 122 and the cloth lamp 200 increases the friction between the corner buckle device 100 and the cloth lamp 200, thereby strengthening the fixing effect. Even when subjected to external force, it can maintain good stability and is not easy to fall off or shake. In some embodiments, the side of the protrusion 122 close to the cloth lamp 200 is configured to be elastic to avoid wear on the cloth lamp 200 when the protrusion 122 is pressed on the cloth lamp 200. In addition, since the protrusion 122 has a certain elasticity, the corner buckle device 100 can be applied to cloth lamps 200 of different thicknesses, ensuring that a good fixing effect can be achieved in different situations.

[0043] See also Figure 4 , the groove 1112 has a plurality of mounting holes 1111, and the avoidance hole 113 is located between adjacent mounting holes 1111. In some embodiments, the first connecting member 121 is a columnar protrusion, and the first connecting member 121 is configured to be able to pass through the mounting hole 1111. The raised portion 122 is configured to be able to abut against the surface of the light fixture 200 located in the first accommodating space 130 through the avoidance hole 113. Therefore, the avoidance hole 113 is provided between adjacent mounting holes 1111, which is conducive to balancing the pressure of the raised portion 122 on the light fixture 200, and avoiding local overpressure that may cause damage to the light fixture 200.

[0044] A mounting portion 150 is provided on one side of the corner buckle device 100 away from the first accommodating space 130. The mounting portion 150 is provided with a through hole 151. The through hole 151 is configured to be connected to an external device to store the corner buckle device 100 or to hang the corner buckle device 100. Figure 4 , a mounting portion 150 is provided on the side of the corner buckle device 100 away from the first accommodating space 130, and the design of the through hole 151 enables the corner buckle device 100 to be easily connected to an external device to achieve a mounting or storage function. While improving the user's convenience of use, it also improves the space utilization rate. The design of the through hole 151 enables the corner buckle device 100 to be applicable to a variety of scenarios. For example, the cloth lamp 200 can be hung on a wall, ceiling or bracket through the mounting portion 150. The adaptability and flexibility of the corner buckle device 100 in practical applications are improved. In addition, compared with the related art of punching holes on the side of the cloth lamp 200 to facilitate the hanging of the cloth lamp 200, the mounting portion 150 is arranged on the corner buckle device 100 in the present application, which is conducive to reducing the number of holes punched in the cloth lamp 200, thereby improving the structural strength of the cloth lamp 200 while increasing the luminous area of ​​the cloth lamp 200. In other embodiments, the mounting portion 150 is provided with a magnetic component or a suction cup structure, so as to facilitate the user to fix the corner buckle device 100 on various planes.

[0045] In some embodiments, the shape of the light strip 200 can be polygonal, and the corner buckle device 100 is installed at the corners of the light strip 200. Please refer to Figure 1 , the first support plate 111 is located on the light-emitting side of the light strip 200, and the side of the first support plate 111 facing away from the mounting portion 150 has a first wall surface 1113, the first wall surface 1113 is arc-shaped, and the first wall surface 1113 is recessed in the direction close to the mounting portion 150. The first support plate 111 is located on the light-emitting side of the light strip 200 and is designed with an arc shape, so that while the corner buckle device 100 meets the practical function, it can also be used as a decorative element of the light strip 200, improving the overall aesthetics of the light strip 200. The arc-shaped design of the first wall surface 1113 enables the corner buckle device 100 to reduce the occupation of the light-emitting area of the light strip 200 while meeting the functional requirements, increasing the area of the light-emitting area of the light strip 200, and making the overall structure more compact. It should be noted that if the shape of the first wall surface 1113 matches the edge of the light-emitting area of the light strip 200, and the edge of the light-emitting area of the light strip 200 is right-angled, the shape of the first wall surface 1113 is also configured to be right-angled.

[0046] In some embodiments, please refer to Figure 4 , the side wall of the groove 1112 is curved in an arc shape, and the bending direction is the same as that of the first wall surface 1113, and the contour shape of the pressing member 120 is adapted to the groove 1112. The arc-shaped bending design of the side wall of the groove 1112 enables the corner buckle device 100 to adapt to light strips 200 of different sizes and shapes. Whether it is a circular, square or other irregularly shaped light strip 200, as long as its side can be inserted into the first accommodating space 130, the corner buckle device 100 can be applied. The side wall of the groove 1112 is curved in an arc shape, and the bending direction is the same as that of the first wall surface 1113. This design enables the corner buckle device 100 to better disperse stress when subjected to an external force, thereby enhancing the structural stability.

[0047] To ensure that the corner buckle device 100 has a good supporting effect on the cloth lamp 200 while reducing the influence of the corner buckle device 100 on the light-emitting area of the cloth lamp 200, in some embodiments, a plane perpendicular to the direction from the first support plate 111 to the second support plate 112 is defined as the projection plane. The projection of the second support plate 112 on the projection plane covers the projection of the first support plate 111 on the projection plane, and the projection area of the second support plate 112 on the projection plane is larger than the projection area of the first support plate 111 on the projection plane. The projection area of the second support plate 112 on the projection plane is larger than that of the first support plate 111, enabling the second support plate 112 to better support the cloth lamp 200, improving the stability and safety of the cloth lamp 200 during installation. Since the projection area of the second support plate 112 is relatively large, it can better disperse the weight of the cloth lamp 200, reduce the stress on the first support plate 111, and extend the service life of the corner buckle device 100.

[0048] The second aspect of the present invention also provides a supplementary lighting device 10. Please refer to Figure 1 , the supplementary lighting device 10 includes a cloth lamp 200 and the corner buckle device 100 described in any of the above embodiments. Among them, the cloth lamp 200 includes a substrate 210 and a light-emitting component 220 mounted on the substrate 210. The substrate 210 includes an edge portion 211 wound around the periphery of the light-emitting component 220. The corner buckle device 100 is adapted to be mounted on the edge portion 211 to provide a supporting effect on the cloth lamp 200, thereby facilitating the deployment of the cloth lamp 200. The provision of the corner buckle device 100 makes the installation of the cloth lamp 200 more stable and safe, extends the service life of the supplementary lighting device 10, and the corner buckle device 100 composed of the support member 110 and the pressing member 120 is convenient for disassembly and replacement, facilitating the user to repair and replace the cloth lamp 200 and improving the repair efficiency. The corner buckle device 100 of the present application can be applicable to cloth lamps 200 of different specifications and shapes, reducing the production cost and usage cost.
