Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a pentahedral case for use in a storage cabinet formed by a bottom plate, a top plate, and a side plate, or in a test tank of a testing machine. The present invention relates to an assembly-type case that can be assembled by using the following methods.

A pentahedral case originally used for a storage or a test tank of a testing machine (normal cases are hexahedral, but a case used for a storage or a test tank of a testing machine has a door on the front). The top plate, bottom plate, and side plates were made to fit the size of the front frame of the pentahedron (because the front frame of The joints of the side plates may be butted or overlapped, and the joints may be assembled by welding or fixed with fastening materials such as rivets or bolts, or alternatively, the top plate, side plates, and bottom plate may be assembled. The side plates, left and right rear side plates are connected in advance by bending, and the joints are butted or overlapped and welded or with fastening materials such as rivets. It is usually assembled in a fixed manner.

However, in cases assembled in this way, the side plates are often larger than the top and bottom plates, making handling very inconvenient. Since the joints where the materials are joined are butted or overlapped, a large number of fastening materials such as welding or rivets must be used, and the work is extremely complicated and requires a great deal of effort. Moreover, welding requires a high level of skill, and at the same time, the constituent materials of the top plate, bottom plate, and side plates must be manufactured each time to suit the size of the case. Furthermore, since some of the constituent materials are connected in advance, it is difficult to handle, which is extremely disadvantageous in terms of work and cost.

The present invention is an assembly type case in which the combination of the bottom plate, side plate, and top plate constituting the case is assembled by a fitting method, and the bottom plate and the top plate must be manufactured to match the size of the case. However, if you make the side plates in a certain size in advance and combine them according to the size of the case, you can easily produce a case of any size in a short period of time, and you can combine them. It has the advantage of not requiring a high degree of skill in welding and can reduce the amount of fastening materials such as welding or rivets, and can be manufactured extremely efficiently, and eliminates the above disadvantages. It is.

Hereinafter, the present invention will be explained with reference to the drawings. Bottom plate A
is made up of an outer bottom frame 2 and an inner bottom frame 4 that are fitted together, and the outer bottom frame 2 is a bat-shaped piece with a protruding edge 1 that is uniformly protruded by bending the entire circumference of the plate. Similarly to the outer bottom frame 2, the inner bottom frame 4 is a bat-shaped piece with a protruding edge 3 that protrudes uniformly by bending the entire circumference of the plate, so that it fits slightly inside the outer bottom frame 2. small size, and when they are fitted together, the periphery between the outer bottom frame 2 and the inner bottom frame 4 is the side plate B.
Interval T (for example, side plate B,
The projecting edges 1 and 3 are for holding the side plates B, B' and B''.

The side plate B is provided with a bent upright part by bending both ends so that the cross section forms a square shape, and a locking hole 6 is provided in one side part 5 of the bent upright part, and a locking piece 8 is provided in the other side part 7. A plurality of these are provided so that the side plates are connected and engaged with each other, and cutouts are provided at the top and bottom of the folded upright parts 5 and 7 so that they can be inserted and combined into the space T between the bottom plate A and the top plate C to form a box body. 9 and 10 are provided. Side plate B' is a corner side plate used at the corner of the case, and is exactly the same as side plate B, and is bent at an appropriate position 16 to form side plate B.
The side plate B'' is a front corner side plate used at the front corner where a door, extractor, etc. are provided in the case, and the cross section is L. The front part 17 is formed by bending it into a letter shape, and one side of the front part 17 is further bent in the same manner as the side plate B to provide a bent upright part, and the bent upright part is connected and engaged with the side board B. A locking hole 6 or locking piece 8 is provided to connect and engage with the side plate B.

Like the bottom plate A, the top plate C has an inner top frame 12 and an outer top frame 1.
4 and 4 are fitted together, and the inner top frame 12 is shaped like a butt with a projecting edge 11 formed by uniformly bending the entire circumference of the plate, and the outer top frame 14 is formed by fitting the inner top frame 12 into the inner top frame 12. Top frame 1
It is a buck-shaped piece with a projecting edge 13 in the same manner as 2, and is slightly larger so as to cover the outside of the inner ceiling frame 12. When both are fitted together, the outer ceiling frame 14 and the inner ceiling frame 12 are connected to each other.
Side plates B, B',
It is formed to create a spacing T (for example, approximately equal to the thickness t of the side plates B, B', and B'') that can be inserted and combined by inserting the side plates B'', and the projecting edges 11 and 13 are for holding the side plates. .

Providing a locking hole and a locking piece on each side plate to lock and connect the side plates makes it easy to engage and combine the side plates with each other, and does not require skilled techniques, achieving the same effect as welding or riveting. It's for a reason.

To assemble the case according to the present invention, first, as shown in FIG. They are combined and fitted to form the bottom frame A shown in FIG. 2, and as shown in FIG. At the same time, the locking holes 6 and locking pieces 8 provided in the bent upright parts 5 and 7 are inserted until they hit 4.
are gradually inserted and fitted so that they lock with the locking holes and locking pieces of the other side plate B, and are locked and connected to form a combined side plate, and also the corner side plate B' and the front corner side plate B''. In the same manner, the side plates are inserted and engaged and connected to form a desired shape, thereby forming the side wall portion of the housing.

Next, the inner top frame 12 is inserted into the inner upper notch 10 of the side plate of the completed case so as to have the same form as the bottom plate, and the inner top frame 12 and the side plates B, B', and B'' are further enclosed together. In this way, the outer frame 14 is covered with a top plate C to form a cover.

Since the case assembled in this manner is simply fitted together, there is a risk that the fitted portion may come off during handling of the case. To prevent this, the inner bottom frame (inner top frame), the outer bottom frame (outer top frame), and the side plates are secured at each corner of the case by fastening materials 15 such as rivets or bolts, as shown in FIG. By combining and fixing, it is possible to form an extremely strong housing, and the housing will not bend or loosen at all.

As described above, the present invention allows the assembly of the top plate, side plates, and bottom plate components to form a case by fitting them together, so that special techniques such as welding, which were required in the past when forming the case, are not required. The case can be made very easily with only a few fastening materials such as rivets, and although the top and bottom plates need to be made to match the size of the case, the side plates are If the sizes are made in advance, they can be combined to suit the size of the container, making it possible to manufacture them in a short period of time and extremely efficiently without requiring a high degree of skill. It has the advantage of being able to

In addition, in the explanation, the combination of the bottom plate and the top plate is the 6th one.
As shown in Figure a, both the inner and outer plate parts are fitted together in a box-like manner so that they face each other, but even if the plate parts are combined so that they overlap each other as shown in Figure 6 b, the protrusion still works. Of course, since they are the same, it is possible to obtain a shell having the same effect.

In addition, in the case of a test chamber in which a case made in this manner is used under constant temperature and humidity conditions, the case must often be insulated to maintain the temperature and humidity conditions.

In such a case, it is obtained by combining the bottom plate and the top plate into a box shape, inserting a heat insulating material into the box-shaped space, and combining them. By making the resulting interval T equal to the bending length of the folded upright part of the side plate instead of making it equal to the thickness t of the side plate, it is possible to insert a heat insulating material corresponding to the bending length into the side plate part. By attaching a back plate to this, it is extremely easy to create a case with heat insulating properties, and the rational effects of the structure can be fully demonstrated.
