Description

Technical Field

[0001] This utility model relates to storage boxes, and in particular to a rotating connection mechanism for the lid of a storage box. Background Technology

[0002] Storage boxes are used to store loose items and are frequently used in daily life. Most storage boxes have lids, with rotating lids being particularly popular because they are easy to open and close and remain attached to the box after opening, preventing them from being lost. Storage boxes are categorized by material into wooden, metal, and plastic storage boxes. Wooden and metal storage boxes typically use hinges to connect the body and lid. Plastic storage boxes, on the other hand, usually have a protruding upper arc-shaped connecting piece on the top of the body and a corresponding lower arc-shaped connecting piece on the bottom of the lid. Axle holes are formed in both the upper and lower arc-shaped connecting pieces, which are then connected by a rotating shaft passing through these holes. The drawbacks of this structure are that the upper arc-shaped connecting piece is integrally manufactured with the body, and the lower arc-shaped connecting piece is integrally manufactured with the lid. Because the arc-shaped connecting piece is a protruding structure, its structural strength is relatively poor, making it prone to breakage. Once broken, it cannot be repaired, resulting in the body and lid not being able to rotate properly and a short lifespan. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a rotating connection mechanism for the lid of a storage box that has high structural strength, long service life, and is easy to replace after breakage.

[0004] The technical solution of the rotating connection mechanism of the lid of the storage box of this utility model is as follows: it includes a box body, a lid is provided on the upper part of the box body, a rotating component is provided on the inner wall of the box body, one end of the rotating component is rotatably connected to the inner wall of the box body via a rotating structure, and the other end of the rotating component is provided with an upwardly bent plug, which is plugged into the bottom of the lid via a plug-in structure.

[0005] Furthermore, the rotating structure includes connecting pieces on the inner wall of the housing, the connecting pieces being two pieces, left and right, with shaft holes respectively formed in the left and right connecting pieces, forming a connecting groove between the left and right connecting pieces, one end of the rotating component being inserted into the connecting groove, and a rotating shaft being provided on the rotating component, the rotating shaft being rotatably connected to the shaft hole.

[0006] Furthermore, a first reinforcing rib is provided between the connecting piece and the housing.

[0007] Furthermore, the plug-in structure includes spring contacts on both sides of the upper part of the plug, barbs on the outer wall of the spring contacts, a slot at the bottom of the cover, and locking holes on both sides of the slot. The plug is inserted into the slot, and the barbs lock into the locking holes.

[0008] Furthermore, second reinforcing ribs are provided on both sides of the rotating component.

[0009] Furthermore, there are two or more rotating components.

[0010] The beneficial effects of the rotating connection mechanism for the lid of a storage box of this utility model are: 1. The box body and the box cover are connected by a rotating component. The rotating component is a separate structure from the box body and the box cover. If it is damaged, the rotating component can be replaced separately, which is convenient and reduces the replacement cost.

[0016] To further illustrate the content, features, and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and examples, but it should not be construed as a basis for limiting this utility model.

[0017] This utility model relates to a rotating connection mechanism for the lid of a storage box, such as... Figure 1 — Figure 5 As shown, the device includes a box body 1, a box cover 2 on the upper part of the box body 1, a rotating component 3 on the inner wall of the box body 1, one end of the rotating component 3 being rotatably connected to the inner wall of the box body 1 via a rotating structure, and the other end of the rotating component 3 being provided with an upwardly bent plug 4, which is plugged into the bottom of the box cover 2 via a plug-in structure.

[0018] Furthermore, the rotating structure includes connecting pieces 5 on the inner wall of the housing 1. The connecting pieces 5 are two pieces, left and right, with shaft holes 6 respectively opened in the left and right connecting pieces 5. A connecting groove 7 is formed between the left and right connecting pieces 5. One end of the rotating member 3 is inserted into the connecting groove 7. A rotating shaft 8 is provided on the rotating member 3, and the rotating shaft 8 is rotatably connected to the shaft hole 6.

[0019] Furthermore, a first reinforcing rib 9 is provided between the connecting piece 5 and the housing 1. The first reinforcing rib 9 improves the structural strength between the connecting piece 5 and the housing 1.

[0020] Furthermore, the plug-in structure includes spring pieces 10 on both sides of the upper part of the plug 4, barbs 11 on the outer wall of the spring pieces 10, a slot 12 at the bottom of the cover 2, and locking holes 13 on both sides of the slot 12. The plug 4 is inserted into the slot 12, and the barbs 11 are locked with the locking holes 13.

[0021] Furthermore, second reinforcing ribs 14 are provided on both sides of the rotating component 3. The second reinforcing ribs 14 improve the structural strength of the rotating component 3.

[0022] Furthermore, there are two or more rotating parts 3. The number of rotating parts 3 can be increased according to the width of the storage box, usually 2-4.

[0023] This utility model discloses a rotating connection mechanism for a storage box lid. It mainly involves two or more sets of connecting pieces 5 on the inner wall of the rear panel of the box body 1. Each set of connecting pieces 5 consists of two pieces, left and right, forming a connecting groove 7 between them. The width of the connecting groove 7 is the same as or slightly larger than the width of the rotating component 3, allowing one end of the rotating component 3 to fit snugly into the connecting groove 7. The width of the connecting groove 7 and the rotating component 3 can be set between 20mm and 30mm; the wider the rotating component 3, the higher its structural strength. Rotating shafts 8 are provided on both sides of the rotating component 3, and the rotating component 3 is rotatably connected to the shaft holes 6 of the connecting pieces 5 on both sides via the rotating shafts 8. An upwardly curved rectangular plug 4 is provided at the other end of the rotating component 3. Spring pieces 10 are provided on both sides of the upper part of the plug 4, forming gaps between the spring pieces 10 and the plug 4, giving the spring pieces 10 a certain degree of elasticity. A barb 11 is provided on the outer wall of the spring pieces 10. A transverse reinforcing piece 15 and a longitudinal reinforcing piece 16 are provided at the bottom of the lid 2. The structure of the reinforcing plate 16 is such that the transverse reinforcing plate 15 and the longitudinal reinforcing plate 16 intersect to form a rectangular slot 12. The rectangular slot 12 is the same size as the rectangular plug 4, or the rectangular slot 12 is slightly larger than the rectangular plug 4. The barbs 11 on the spring pieces 10 on both sides of the plug 4 are wider than the width of the slot 12. When the plug 4 is inserted into the slot 12, the slot 12 squeezes the barbs 11 of the spring pieces 10, so that the spring pieces 10 can be elastically deformed inward. When the plug 4 is inserted into place, the spring pieces 10 return to their original position under the action of elastic restoring force, and the barbs 11 are engaged in the locking hole 13, so that the rotating part 3 is fixedly connected to the cover 3. If the rotating part 3 is damaged after a long period of use, the barbs 11 can be squeezed slightly with a finger or tool to make the spring pieces 10 elastically deform inward, so that the plug 4 can be dislodged from the slot 12. Then, the connecting piece 5 can be pried slightly with a tool (such as a flathead screwdriver) so that the rotating shaft 8 of the rotating part 3 can be dislodged from the shaft hole 6, so that the rotating part 3 can be removed and replaced. The replacement of parts is convenient.

[0024] Although the embodiments of this application disclose the above-described methods, the content is merely an implementation method adopted for ease of understanding. Any person skilled in the art should understand that any modifications and changes in the form and details of the implementation can be made without departing from the spirit and scope disclosed in this utility model. However, the patent protection scope of this utility model shall still be determined by the scope defined in the appended claims.
