[0034] Reference Figures 1 to 7 According to a first aspect of the present invention, a rounded corner light box includes a frame assembly 100 and an elastic connector 200. The frame assembly 100 includes a plurality of side pieces 110 and corner pieces 120. Corner pieces 120 are provided between each side piece 110. The elastic connector 200 can be bent through the corner piece 120 and can be inserted into and fixedly connected to the side pieces 110 on both sides of the corner piece 120. The corner piece 120 includes at least two types of rounded corner pieces 121 and 122 with different curvatures. The first rounded corner piece 121 or the second rounded corner piece 122 can be selectively connected between each side piece 110. The elastic connector 200 can be elastically deformed, allowing it to be inserted into the first rounded corner piece 121 and the second rounded corner piece 122 with different curvatures, thus adapting to different curvatures. Furthermore, the elastic connector 200 can extend and be inserted and connected to the side plate piece, thereby enabling the frame assembly 100 to replace different corner pieces 120 through the elastic connector 200 without the need to manufacture corresponding connectors separately, resulting in low manufacturing costs.

[0035] Specifically, the frame assembly 100 can be square, the side members 110 can be straight rods, and the corner members 120 can be selected from the first rounded corner members 121. The four side members 110 form a square frame. The first rounded corner member 121 can be connected to two mating side members 110 by an elastic connector 200. The elastic connector 200 can be deformed and bend through the first rounded corner member 121. It can be understood that the first rounded corner member 121 has a channel for the elastic connector 200 to pass through, so that the elastic connector 200 can extend from both ends of the first rounded corner member 121, and the extended elastic connector 200 can be inserted into the side member. The end of 110 can be either an interference fit or a fixed connection via a connecting structure. The specific structure is not limited here. The curvature of the second rounded corner piece 122 is different from that of the first rounded corner piece 121. The curvature of the second rounded corner piece 122 is smaller than that of the first rounded corner piece 121. The elastic connector 200 can still pass through the second rounded corner piece 122 and connect with the side piece 110. Therefore, there is no need to set a corresponding matching connector. Only an elastic connector 200 of the same specification is needed for universal use. The manufacturing cost is low. Furthermore, the first rounded corner piece 121 and the second rounded corner piece 122 can be used interchangeably to meet different usage requirements.

[0036] It should be noted that the frame component 100 can also be other shapes, such as triangles, polygons, etc., and it is understood that more rounded corner pieces with different curvatures can also be provided, not limited to the first rounded corner piece 121 and the second rounded corner piece 122 in the embodiment.

[0037] Reference Figure 2 and Figure 5 In some embodiments of this utility model, the side member 110 is provided with a first connecting rail 111, which extends along the extension direction of the side member 110. The first rounded corner member 121 is provided with a second connecting rail 1211 extending along its arc, and the second rounded corner member 122 is provided with a third connecting rail 1221 extending along its arc. The elastic connector 200 can pass through the second connecting rail 1211 or the third connecting rail 1221 and can be inserted into the first connecting rail 111. Specifically, the first connecting rail 111 extends to both ends of the side member 110 so that the elastic connector 200 can be inserted into the first connecting rail 111. The curvature of the second connecting rail 1211 matches that of the first rounded corner member 121, i.e., it is an arc-shaped rail. The curvature of the third connecting rail 1221 matches that of the second rounded corner member 122. When the first rounded corner member 121 is used for docking, the elastic connector 200 can pass through the second connecting rail 1211 and dock with the first connecting rail 111 of the two side members 110. When the second rounded corner member 122 is used, the elastic connector 200 can pass through the third connecting rail 1221 and dock with the first connecting rail 111 of the two side members 110.

[0038] ReferenceFigures 2 to 7 In some embodiments of this utility model, the elastic connector 200 is strip-shaped and has a plurality of connecting holes 210. The connecting holes 210 are spaced apart along the extension direction of the elastic connector 200. The connecting holes 210 can be threaded with bolts so that the elastic connector 200 is fastened to the side member 110 and the corner member 120. Specifically, the elastic connector 200 can be configured as a long strip and match the mating shape of the first connecting rail 111, the second connecting rail 1211, and the third connecting rail 1221. It can be understood that the length of the elastic connector 200 is set to be able to pass through two adjacent side pieces 110 and corner pieces 120 at the same time. Interval connecting holes 210 can be opened sequentially on the elastic connector 200. The connecting holes 210 are evenly spaced. After the side pieces 110 and corner pieces 120 are properly aligned, bolts or screws can be threaded into the connecting holes 210. The bolts need to be tightened at the corresponding positions on the side pieces 110 and corner pieces 120 to press the elastic connector against the corresponding rails and achieve a tight connection.
