COMBINED AND DISASSEMBLE BOX

The invention relates to the field of containers for storage and transportation of piece goods for various purposes, in particular to containers with detachable reusable items.

Known metal box (damn, No. 461 of the Magnitogorsk plant of mechanical workpieces attached to the application materials), used as a reusable container. The box is a welded structure of walls, bottom And fastening

- A drawer of such a drawer is high metal consumption (to obtain a high-quality welded joint and to ensure the rigidity of the drawer, the metal sheets use a greater thickness than is required by the bearing capacity). The disadvantage is also the high cost of returning, since the drawer keeps its volume empty. Careless attitude to tare containers

when it is overloaded, it leads to its damage, and therefore to the need for repair. The well-known design and safety of the contents does not provide. For this, additional measures (devices) are required, and therefore costs.

Collapsible boxes are known which are devoid of the disadvantages of an analogue.

Closest to the claimed design is a prototype - collapsible box (a, p. USSR No. 412078, class MS B65till / i8, B.I., No. 3, 1974), containing walls connected by a stern passing through hinges mounted on the walls. To connect the lids and the bottom to the walls, the latter at the junctions are bent into the box and provided with slats, and the lid and bottom are made with shoulders. The box can be reused and in a collapsible form takes up much less volume than in the assembled one.

However, such a box is difficult to manufacture, various parts that require quite careful processing. With an increase (if necessary) the carrying capacity of the box, its material consumption

increases greatly. Moreover, crane operations with such a box without special grips (slings) are impossible,

The basis of creating the proposed utility model is set to obtain a technical effect in the form of increasing the carrying capacity of the box without increasing its mass, ensuring the safety of contents, as well as the possibility of stacking boxes.

The problem is solved in that in a collapsible box containing walls connected by rods between you and connected to the bottom and cover, the walls of the cover and bottoms © in places

connections to each other have perforations, which are combined in adjacent parts with their depressions and protrusions through which the locking rods with rings at the ends are passed, used to fasten removable handles. The handles are made with ears that fit into the notches of the parts, for interaction with locking erasers. The bottom of the box is raised relative to the edge of the side walls, and the size around the perimeter of the box at the bottom is larger than the perimeter of the lid by four times the wall thickness

An analysis of the proposed solution reveals the following. All parts of the box are made of metal sheet of small thickness, which makes the mass quite low. It does not entail an increase in the mass of the box and the proposed connection of parts using notches. The cut-outs, connecting with their hollows and protrusions, work like keys and carry the entire load, without requiring reinforcement in the connection mass. The core is compressed only to close the assembly and distributes the load. The presence of rings on the rods makes it possible to seal the box, and therefore control over the safety of contents without additional devices and devices. The sign that the rod is the axis for the handle, on the one hand, allows not to increase the mass of the box due to the strengthening of the mounting places of the handle and its fastening elements, and on the other hand, install a handle on any connection of the elements and transport the box with a crane without special adaptations. Lock connection of drawer elements

together with a raised bottom, they allow to achieve sufficient rigidity not only for transportation but also for stacking,

Based on the analysis of the known solutions and the foregoing

features, we can conclude that the proposed set of features that solve the task is new.

The industrial applicability of the proposed collapsible box is due to the simplicity of manufacturing its parts on stamping presses, ensuring high manufacturing accuracy, the ability to mechanize the manufacturing of parts, the speed of assembly and disassembly, which do not require special equipment, as well as the long-term use of the box parts without repair, their interchangeability.

Therefore, the proposed solution has novelty and industrial applicability and can be recognized as a useful model by the eligibility criteria.

The essence of the utility model is illustrated by drawings, which are presented on

FIG. i is a general view of a collapsible box; FIG. 2 is a section AA in FIG. I (connection of perforations of adjacent elements)

FIG. 3 g section BB in FIG. I (wall connection) of FIG. 4 - locking rod of FIG. 5 W removable handle.

A collapsible box contains a lid I, L - shaped side walls 2 and a bottom 3. In the places of connection of the parts, they have grooves 4, the grooves are alternating protrusions 5 and troughs 6, corresponding to each other in size. It is possible to make cuts in the form of holes (openings) alternating with curved-shaped piers. When assembled, the protrusions of all the parts are located in the hollows of adjacent and closed rods 7. Moreover, the rods connecting the roofs 1 and the walls are arranged in pairs with rings 8 facing each other.

and sealed (not shown). On horizontal (possibly vertical) rods 7, handles 9 are installed with their own ears 10, the size of which corresponds to the size of the notches, which, when combining the protrusions 5 and the ears 10, simultaneously snap them together with the rod 7.

The notches along the bottom of the side walls are located so that the bottom 3 in the assembled box is raised to form a cavity, which is used when stacking the boxes.

The assembly of the Core is as follows. Slots 4 made on the flanges of the bottom 3 are combined with the slots of the first side wall 2.

The semi-learned connection is closed by the rod 7, setting it so that the ring 10 is inside the box. Locking the first horizontal rib, the vertical connection of the lateral L-jubular walls 2 is combined with each other. The rods 7 are inserted into the ring 10. So alternately connect all the walls 2 with the bottom 3 to each other.

After that, the contents are loaded into the box.

The box cover 1 is put on top of the wall 2, combining the notches of each side of the lid with the upper notches of the walls. At the same time, in two opposite walls of the notch 4, they are combined with the ears 10 of the handles 9 and the rods 7 are threaded into the connection points 5 and the ears 10.

In the assembled box, the rods 7 connecting the lid are installed in pairs with rings facing each other, which allows the box to be sealed. Without removing the caps, disassembling the box is impossible, which provides control over the safety of the contents.
