Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic product accessories, and in particular to a glue-free self-locking carrying box. Background Technology
[0002] Locking self-locking handle boxes are a commonly used type of packaging box. The structure of commonly used locking self-locking handle boxes is shown in patent publication document CN203781029U. In this type of packaging box, the locking part of the lid and handle is similar to a blade that is locked in a hole (i.e., point contact when locked). When carried, the blade tends to move towards one side of the hole. Therefore, this type of packaging box has high requirements for the weight of the items when packaging them. When the items are heavy, the hole may be stretched or even torn open, resulting in relatively poor reliability. Utility Model Content
[0003] To address the aforementioned problems, this utility model proposes a glue-free self-locking carrying box. After the lid is sealed, the first and second locking plates bear the force. Compared to point contact, surface contact has a larger force-bearing surface, preventing the box from stretching and cracking, and making it less prone to tearing.
[0004] The technical solution adopted by this utility model is as follows:
[0005] A glue-free self-locking carrying box includes a box body and a box bottom. The box bottom is located at one end of the box body. It also includes a first cover, a second cover, a first locking plate, and a second locking plate. The first cover, second cover, first locking plate, and second locking plate are distributed around the perimeter of the box body. A first handle is attached to the first cover, and a second handle is attached to the second cover. A first latching opening is provided on the first cover, and a second latching opening is provided on the second cover. When the box is sealed, the first and second covers are in the same plane, and the first and second handles are parallel, close together, and perpendicular to the first cover. One end of each handle is locked in the first latching opening, and the other end is locked in the second latching opening. The first locking plate is close to and parallel to the first and second covers, and the second locking plate is close to and parallel to the first and second covers.
[0006] In this type of packaging box, by setting a first locking piece and a second locking piece, after the first cover and the second cover are closed on the box body to complete the sealing, the first cover and the second cover form a box lid. The box lid and the box bottom are located at opposite ends of the box body. The first handle and the second handle are in a close and parallel state, forming a handle. The handle is perpendicular to the first cover and the second cover. The first locking piece locks with the handle through its first locking slot, and the second locking piece locks with its own locking mechanism. The second locking tab engages with the handle. After locking, the first locking tab presses down on the lid, and the second locking tab presses down on the lid. Once the entire box is locked, both the first and second locking tabs press down on the lid. At this point, the locking relies on the pressing action of the first and second locking tabs on the lid. When this type of box is carried by hand, the force is borne by the first and second locking tabs. Compared to point contact, surface contact has a larger force-bearing surface, preventing the box from stretching and cracking, and making it less likely to be torn.
[0007] In summary, after the packaging box is sealed, the first and second locking plates bear the force. Compared with point contact, surface contact has a larger force-bearing surface, so it will not expand and crack, and it is not easy to be torn.
[0008] Optionally, the box body is provided with a first support piece and a second support piece, the first support piece being used to support the first cover piece and the second cover piece, and the second support piece being used to support the first cover piece and the second cover piece.
[0009] Optionally, the box body includes a first side piece, a second side piece, a third side piece, and a fourth side piece, and the box bottom is a sheet-like box bottom. The first side piece, the second side piece, the third side piece, and the fourth side piece are distributed around the four sides of the box bottom, and the first side piece, the second side piece, the third side piece, and the fourth side piece form the box body.
[0010] Specifically, the first and third side pieces are parallel and not in contact, as are the second and fourth side pieces. The second side piece is located between the first and third side pieces, and the fourth side piece is located between the first and third side pieces.
[0011] Specifically, the first locking plate and the first support plate are both disposed on the second side plate, and the second support plate and the second locking plate are disposed on the fourth side plate.
[0012] Optionally, the first side piece is provided with a first locking piece and a second locking piece, and the third side piece is provided with a third locking piece and a fourth locking piece, wherein the first locking piece and the fourth locking piece are engaged together.
[0013] Optionally, the second and third locking tabs are attached to the fourth side tab, the first and fourth locking tabs are attached to the second side tab, and the second and third locking tabs are attached to the fourth side tab.
[0014] Optionally, the first cover and the second cover have the same shape and size.
[0015] Optionally, the first handle piece and the second handle piece have the same shape and size.
[0016] Optionally, the first locking piece and the second locking piece have the same shape and size, and the first locking opening and the second locking opening have the same shape and size.
[0017] The beneficial effects of this utility model are: after the capping is completed, the first and second locking plates bear the force. Compared with point contact, surface contact has a larger force-bearing surface, so there will be no phenomenon of expansion and cracking, and it is not easy to be torn apart.
