Description

Assembly box kit {FABRICATED BOX KIT}

The present invention is mainly for use as a control box for mounting the electric circuit connection circuit or control circuit of the training training equipment, can also be used for general storage, in particular using a box of different sizes using the same standard parts An assembly box kit that can be assembled.

Boxes are used in various fields besides general storage, and are provided in various materials, structures, and sizes depending on the purpose.

The assembly box enables the assembly of a box of a complicated structure by forming a part or all parts of the box by parts, and in particular, by standardizing parts, mass production and maintenance are easy.

Conventionally, assembling boxes of various structures have been proposed, but educational training tables such as FIG. 1 to which an assembly box closest to the subject of the present invention is applied are commercially available. The training table for training of FIG. 1 has been disclosed in the Republic of Korea Utility Model Registration 20-0248766, the support (2) is erected on the general table (1), the training plate (4) and the rack frame (5) is installed. Various training equipments 5 can be arranged and fixed on the training board 4, and the rack frame 5 can be fixed to control box 6 for electrical wiring connection and control thereof to the training equipments 5. Can be. The control box 6 may also be arranged on the training plate 4.

The control box (6) is a built-in modular circuit according to the training equipment, and to configure the panel for the electrical wiring connection or control operation on the cover, which can be provided in various standards according to the module of each circuit or panel. There is a need.

Regarding such a control box, the registered utility model 20-0248766 teaches a structure in which the box body and the two side plates are assembled. The box body is formed by cutting a continuous extrusion molding made of aluminum to a desired length. The box body has a front portion, a rear portion and a bottom portion corresponding to an open rectangular box, and has left and right side portions removed. The side plate is provided as a plastic injection molded in a shape corresponding to the removed left and right side portions of the box body. The box body and side plates are fastened with separate screws. That is, the box assembly can be made to fit the size of each circuit module by cutting the extrusion molding for the box body according to the circuit module to an appropriate length.

Designing and manufacturing each box separately to provide the same structure box in various sizes is uneconomical as it is expensive. Therefore, it is economically meaningful to prefabricate the box and to be able to use it in the desired size.

The prefabricated structure of the control box according to the prior art as mentioned above is disadvantageous for mass production because the box body must be cut to fit the desired size. In addition, in the prefabricated structure, the assembly state must be robust, and for this purpose, it is not preferable to use a mechanical element such as a bolt or a screw in order to reduce its assemblability.

Therefore, the present invention, in view of the above-described problems of the prior art, first assembling box kit that can be assembled in a variety of sizes using a single standard parts as a simple fitting structure of the assembly structure improved to the easy assembly and robust assembly state To provide.

The assembly box kit according to the present invention to achieve the above object is provided with one or more box body of the front and rear and bottom and the bottom portion is formed integrally and the left and right side portions corresponding to the open top of the rectangular box is removed, Two side plates having sizes and shapes corresponding to the removed side portions of the box body are provided, and one or more connecting frames are formed integrally and narrowly with the front portion, the rear portion and the bottom portion corresponding to the box body. Couplings with concave-convex surfaces are formed at each of the left and right corners of the front and rear portions of the box body, and corresponding portions of the side plates each have corresponding concave-convex surfaces that fit snugly to the concave-convex surface of the box body. And a corresponding uneven surface of each side plate corresponding to the uneven surface of the box body is formed in the connection frame. The concave-convex surface of the same shape is formed in a symmetrical shape, characterized in that configured to connect two or more of the box body in sequence to the connecting frame.
