Description

Technical Field

[0001] This application relates to the technical field of storage box covers, and in particular to a rounded corner structure of a cover plate. Background Art

[0002] In the fields of industrial design, architectural decoration, furniture manufacturing, etc., rounded corner structures are widely used because of their beautiful appearance, safety and anti-collision, etc. For a solid wood structure on the cover plate of a storage box, it is relatively easy to process rounded corners. However, for a cover plate made of a hollow metal sheet or other materials, it is often difficult to directly bend it. And simple connection or internal welding between the cover plate and the rounded corner plate often results in many seams, which are not satisfactory in terms of aesthetics and safety, and internal welding leads to unstable welding quality and a decrease in the product yield rate.

[0003] The above content is only used to assist in understanding the technical solution of this application, and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0004] Based on this, this application provides a rounded corner structure of a cover plate to solve one of the above technical problems.

[0005] The technical solution adopted by this application to solve its technical problems is: a rounded corner structure of a cover plate, which includes: a cover plate frame, including a first plate, a second plate, and a connecting plate. The edges of the first plate and the second plate are connected by the connecting plate, and there is a gap between the connecting plates and an opening is formed; a support frame, installed inside the cover plate frame for supporting the connecting plate; a rounded corner plate, including an arc surface and an abutting surface. The abutting surface is arranged at both ends of the arc surface and abuts between the support frame and the cover plate frame, and the arc surface is arranged on the opening.

[0006] In some embodiments, the first plate and the second plate are provided with arcs at the opening that cooperate with the arc surface.

[0007] In some embodiments, the inner width between the first plate and the second plate is equal to the width of the rounded corner plate.

[0008] In some embodiments, there is a turning point between the arc surface and the abutting surface.

[0009] In some embodiments, the turning corners of the support frame are set as rounded corners that fit the inner diameter of the arc surface.

[0010] In some embodiments, the support frame includes a first contact surface, a second contact surface, and a support surface. The rounded corner plate is supported by the support surface, the first contact surface abuts on the first plate, and the second contact surface abuts on the connecting plate.

[0011] The beneficial effects of the present application are as follows: An opening formed by the rounded corner plate being disposed between the first plate and the second plate. The rounded corner plate is disposed within the opening and is abutted by the first plate and the second plate at both ends of the arc surface, such that the cooperation between the first plate, the second plate and the arc surface nearly eliminates the joint, and the cooperation is also tighter. Moreover, the arc surface is supported by the support frame, which can effectively enhance the support strength of the rounded corner. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of the present application.

[0021] In the embodiments of the present application, please refer to Figures 1-6 As shown, the present application provides a rounded corner structure for a cover plate, mainly including: a cover plate frame 1, including a first plate 11, a second plate 12, and a connecting plate 13. The edges of the first plate 11 and the second plate 12 are connected by the connecting plate 13, and there is a gap between the connecting plates 13 and an opening 14 is formed; a support frame 2, installed inside the cover plate frame 1 for supporting the connecting plate 13; a rounded corner plate 3, including an arc surface 31 and an abutting surface 32. The abutting surface 32 is provided at both ends of the arc surface 31 and abuts between the support frame 2 and the cover plate frame 1, and the arc surface 31 is provided on the opening 14.

[0022] With such a setting, an opening 14 is formed by the rounded corner plate 3 being arranged between the first plate 11 and the second plate 12. The first plate 11 and the second plate 12 abut at both ends of the rounded corner plate 3, and the radius of the arc surface 31 is the same as that of both ends of the first plate 11 and the second plate 12, approaching an integral state. The connecting plate 13 and the support frame 2 effectively fix the abutting surface 32, preventing the rounded corner plate 3 from falling off the opening 14 and playing a role in strengthening the overall cover plate at the same time.

[0023] Next, some preferred / improved embodiments based on the above embodiments will be further elaborated. Any one or a combination of multiple of the following embodiments can be selected.

[0024] Refer to Figure 2 As shown, the first plate 11 and the second plate 12 are provided with arcs matching the arc surface 31 at the opening 14. With such a setting, when the rounded corner plate 3 is installed, it can be consistent with the arcs of the first plate 11 and the second plate 12, making the rounded corner structure closer to an integrally formed state.

[0025] Specifically, in order to make the rounded corner plate 3 closely adhere to the first plate 11 and the second plate 12 to reduce the joint, the inner width between the first plate 11 and the second plate 12 is equal to the width of the rounded corner plate 3.

[0026] Refer to Figure 6As shown, there is a turning point 33 between the arc surface 31 and the abutting surface 32. With this setting, the turning point 33 enables the outer contour of the arc surface 31 to fit the plane of the connecting plate 13 when the abutting surface 32 is supported by the first plate 11 and the support frame 2, making the rounded corner structure closer to the state of integral molding.

[0027] Referring to Figure 3 As shown, in order to enable the support frame 2 to support the arc surface 31 while fixing the abutting surface 32 and strengthen the support strength of the arc surface 31, the turning corner of the support frame 2 is set as a rounded corner that fits the inner diameter of the arc surface 31.

[0028] Referring to Figure 5 As shown, the support frame 2 includes a first contact surface 21, a second contact surface 22, and a support surface 23. The support surface 23 supports the rounded corner plate 3. The first contact surface 21 abuts against the first plate 11, and the second contact surface 22 abuts against the connecting plate 13. With this setting, the support points of the support frame 2 are provided, and at the same time, the installation of the support frame 2 is made more stable, thereby ensuring the stability of the rounded corner plate 3.
