Detailed Description

The present invention will be described in further detail below with reference to the accompanying drawings by way of specific embodiments. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. Furthermore, the technical features mentioned in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 to 6, a multi-functional plastic case is shown.

The multifunctional plastic box comprises a box body 1, an expansion connecting piece group, an expansion connecting belt 6 and the like.

The box body 1 is composed of a box upper half shell 11 and a box lower half shell 12. The box body upper half shell 11 and the box body lower half shell 12 are hinged through a rotating shaft.

The upper tank half shell 11 has an upper half shell top wall 111 and an upper half shell peripheral wall 112. The upper half shell top wall 111 and the upper half shell peripheral wall 112 together define a downwardly open upper half shell interior space. The bottom surface of the top wall 111 of the upper half shell is formed with honeycomb reinforcing ribs 2. The honeycomb reinforcing rib 2 is formed by splicing a plurality of regular hexagons (complete regular hexagons and incomplete regular hexagons). The honeycomb reinforcing ribs 2 are distributed over or substantially distributed over the bottom surface of the top wall 111 of the upper half shell. The honeycomb reinforcing ribs 2 are provided for the purpose of reinforcing the structural strength of the upper half shell top wall 111 without increasing the wall thickness of the upper half shell top wall 111. A plurality of top wall positioning posts 3 are also formed on the bottom surface of the top half shell top wall 111. The plurality of top wall positioning columns 3 are arranged at intervals along the extending direction of the upper half shell peripheral wall 112. And, each of the top wall positioning pillars 3 is close to the upper half casing peripheral wall 112. The bottom surfaces of the top wall positioning columns 3 and the bottom surfaces of the honeycomb-shaped reinforcing ribs 2 are positioned on the same plane. When the built-in storage bag 7 is arranged in the built-in space of the upper half shell, the built-in storage bag 7 is abutted against the honeycomb-shaped reinforcing ribs 2, and the built-in storage bag 7 and the honeycomb-shaped reinforcing ribs are in plane contact, so that the shock resistance of the built-in storage bag 7 is facilitated. Preferably, each top wall positioning column 3 is connected with the honeycomb-shaped reinforcing rib 2 into a whole, so that the structural strength of the top wall positioning column 3 is increased, and the top wall positioning column is not easy to bend or damage due to long-term use. A plurality of T-shaped positioning ribs 4 are formed on the inner face of the upper housing half peripheral wall 112. The plurality of T-shaped positioning ribs 4 are arranged at intervals along the extending direction of the upper half shell peripheral wall 112. It can be seen that any two adjacent T-shaped positioning ribs 4 on the same side and the upper half-shell peripheral wall 112 can jointly form a positioning slot. Preferably, the T-shaped positioning ribs 4 and the top wall positioning pillars 3 are offset from each other in the extending direction of the upper half casing peripheral wall 112.

The lower tank half 12 has a lower half bottom wall 121 and a lower half peripheral wall 122. The lower half-shell bottom wall 121 and the lower half-shell peripheral wall 122 together define a lower half-shell built-in space that is open upward. The lower half-shell bottom wall 121 is formed on its top surface with honeycomb reinforcing ribs 2. The honeycomb reinforcing rib 2 is formed by splicing a plurality of regular hexagons (complete regular hexagons and incomplete regular hexagons). The honeycomb reinforcing ribs 2 are distributed over or substantially distributed over the top surface of the bottom wall 121 of the lower half shell. The honeycomb reinforcing ribs 2 are provided for the purpose of reinforcing the structural strength of the lower half-shell bottom wall 121 without increasing the wall thickness of the lower half-shell bottom wall 121.

In this embodiment, the expansion link group has two expansion links 5. The two expansion joints 5 are disposed on opposite sides of the upper half shell peripheral wall 112. The expansion joint 5 is at the junction of the upper half shell top wall 111 and the upper half shell perimeter wall 112. The expansion connecting piece 5 is an L-shaped structural piece. The expansion link 5 has a horizontal portion 51 and a vertical portion 52. The top surfaces of the lateral portions 51 are in surface contact with the bottom surfaces of the honeycomb reinforcing ribs 2, and the honeycomb reinforcing ribs 2 support the lateral portions 51 well. The transverse portion 51 is covered with the top wall positioning column 3. The top wall positioning column 3 is formed with a connecting hole 30. The lateral portion 51 is formed with a to-be-connected hole 510 corresponding to the connection hole 30. A screw is provided between the coupled hole 510 and the coupling hole 30 as a coupling member so that the lateral portion 51 is fixed to the honeycomb reinforcing ribs 2. The outer face of the vertical portion 52 is in surface contact with the inner face of the upper half-shell peripheral wall 112. The vertical parts 52 are clamped in two adjacent T-shaped positioning ribs 4.

The expansion joint strips 6, such as elastic bands, are connected from one expansion joint 5 to another expansion joint 5, forming stops. The extension connecting belt 6 is used for preventing the built-in storage bag 7 from turning over in the built-in space of the upper half shell. It is easy to find out that, in order to better prevent the inner storage bag 7 from flipping over, a plurality of sets of the extension connecting strips and the extension connecting strips 6 may be provided, wherein the plurality of sets of the extension connecting strips may be parallel or crossed. That is, the user can expand it according to his own needs.

It should be noted that the internal storage bag 7 in the present embodiment is only an example, and in other embodiments, tools, books or other objects may be replaced.

In other embodiments, the box body 1 may further include 4 strap seats, and different connection combinations of the straps may be used to achieve arbitrary conversion between a single-shoulder strap and a double-shoulder strap, so that the box body may be carried by hand or by a single-shoulder strap for a short time or a light weight, and the double-shoulder strap may greatly reduce the burden of the user for a long time or a heavy weight.

In other embodiments, the box body 1 may be further provided with a combination lock for general protection.

In other embodiments, the box body 1 may further be provided with a signboard slot box, so that identification is facilitated after inserting the signboard.

In other embodiments, a sealing strip is disposed on one of the upper shell half perimeter wall 112 and the lower shell half perimeter wall 122 to improve sealing performance.

The above description is only intended to illustrate embodiments of the present invention, and the description is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
