It can have its own fixing force without having a separate fixing means.

If the present invention is described in more detail as described above,

As shown in FIGS. 1 and 2, the connection pipe 10 is formed in a quadrangular shape with four sides, and an insertion groove 12 is formed on each side in the longitudinal direction, so that the closing cap ( The insertion part 31 of 30) is inserted.

At this time, a groove portion (not shown) corresponding to the protrusion 22c formed on the edge portion 22 of the square panel 20 may be formed in the insertion groove 12 of the connecting pipe 10, and the connecting pipe ( When 10) is coupled to the edge portion 22 of the square panel 20, the connection pipe 10 is not easily separated even if shaking or shock occurs as the protrusion 22c is engaged by the groove portion. there is

In the present invention, the groove portion is not shown, and when the connecting pipe 10 is inserted into the edge portion 22, the protrusion 22c has a stronger frictional force so that it does not easily fall out.

On the other hand, as shown in FIGS. 2, 3 and 4, the square panel 20 is formed with an edge portion 22 inserted into the insertion groove 12 of the connection pipe 10, and the edge portion 22 ) has a first edge portion 22a extending from the square panel 20, and one or more protrusions 22c extending from the first edge portion 22a but having a larger width and forming one or more protrusions 22c on the outside and protruding at both ends. It is composed of second edge portions 22b on which the jaws 22d are formed, respectively.

As shown in FIGS. 4, 6, and 7, the first edge portion 22a substantially extends from the rectangular panel 20, and the second edge portion 22b includes the first edge portion 22a. As a configuration extending from), the first and second edge portions 22a and 22b are formed to correspond to the shape of the insertion groove 12 of the connection pipe 10 and are naturally slidably coupled, and the protrusion 22c ) is in close contact with the inserted connection pipe 10 so that the connection pipe 10 does not easily fall out.

In addition, although not shown inside the connection pipe 10, when the connection pipe 10 is completely inserted into the edge portion 22, a groove (not shown) is formed at a position corresponding to the protrusion 22c. , By completely fitting the protrusion 22c into the groove (not shown), it is possible to have a more robust fixing force.

At this time, in the case of the protruding jaw 22d, as shown in FIG. 7 or 8, the connection pipe 10 can be prevented from coming off while being coupled to the edge portion 22 of the square panel 10. It is prepared to be inserted into the closing cap 30 so as to be inserted through the inlet hole 33 formed in the closing cap 30 so that the closing cap 30 can be fixed.

That is, the protruding jaw 22d is formed higher than the upper side of the second edge portion 22b, and is inserted into the inlet hole 33 of the closing cap 30 and then caught on the outside of the closing cap 30. It becomes.

As shown in FIG. 5 or 8, the closing cap 30 is formed with an insertion portion 33 inserted into the insertion groove 12 of the connecting pipe 10, respectively, and each insertion portion 33 Inlet holes 33 are formed at the bottom of the through hole 33 into which the protruding jaw 22d is inserted.

At the same time that the insertion part 33 is inserted into the insertion groove 12 of the closing cap 30, the protruding jaw 22d is introduced into the insertion hole 33 and is introduced to the outside in the opposite direction to the introduction of the protruding jaw ( The end of 22d) comes into contact with the outside of the finishing cap 30 to be caught and fixed.

Even without a separate fixing means (bolts, etc.), there is an effect of being able to have the same or similar level of fixing force as if combined using a fixing means (bolts, etc.) using only the structure.

In addition, through the structure of the closing cap 30 and the protruding jaw 22d, it is not necessary to form a hole for coupling a separate fixing means (such as a bolt) to the connecting pipe 10 and the closing cap 30. , When configuring a storage box by assembling a plurality of connecting pipes 10, square panels 20, and closing caps 30, no separate tools are required, so that the convenience of assembly can be provided.

On the other hand, as shown in FIG. 9, the square panel 20 is a part that can directly contact or collide with other items stored in the storage box when the storage box is configured, and the friction occurs. The portion can be varied to have elasticity, so that the storage space can be expanded and the damage of the square panel 20 can be suppressed if necessary.

In order to achieve this effect, the square panel 20 is formed inside the edge portion 21 in which each edge portion 22 is formed on the outer slope, and the edge portion 21 is disposed and fixed to the outside. and an outer plate 23 formed with a plurality of protruding frames on the outside, and an inner plate 25 formed inside the rim portion 21 but disposed inwardly and not fixed and having a plurality of protruding frames formed on the inside, , Between the outer plate 23 and the inner plate, the inner plate 25 is composed of an elastic member 27 that acts elastically when pushed.

In other words, the outer plate 23 takes a completely fixed form at the rim portion 21, and the inner plate 25 is configured to be movable in an inward and outward direction at the rim portion 21, and the elastic member (27) always pushes the inner plate 25, so that when the inner plate 25 is not pushed by an article, etc., it maintains a state of being completely in close contact with the inside, and is pushed by the article more than the pushing force of the elastic member 27. When the force is stronger, the inner plate 25 is pushed toward the outer plate 23, and when the force applied to the inner plate 25 disappears, the elastic member 27 naturally moves the inner plate 25 It can be restored to a state in which it is in close contact with the inner side as much as possible.

Here, the protruding frames are configured to increase durability of the inner plate 25 and the outer plate 23, and the protruding frames are spaced apart from each other and formed to be connected.

Through the structure of the square panel 20, it is possible to secure a little more space for items in the state where the storage box is configured, and by storing a little more items in the secured space, when the storage space is completely filled in the space of the storage box as in the prior art, the items are placed on top of the storage box. It is possible to suppress other problems such as falling during transportation by stacking.

On the other hand, as shown in FIG. 10 or 11, the closing cap 30 extends upward from the insertion portion 31 of the closing cap 30 but has a bent portion 32 bent outward, When the closing cap 30 is inserted into the insertion groove 12 of the connecting pipe 10, the bent portion 32 surrounds the outside of the connecting pipe 10 so as to be fitted.

While the insertion part 31 is inserted into the connecting pipe 10, the bent part 32 wraps around the outside of the connecting pipe 10, so that the edge part 22 has an impact from any direction along with the protruding jaw 22d Even if it comes, it is possible to easily suppress separation and damage through balanced fixing as a whole.

In addition, when the bent part 32 surrounds the connection pipe 10 and forms the central part of both ends around the insertion groove 12, it can have a more stable fixing force.

According to the prefabricated storage box with improved fixing power of the present invention, while maintaining the original purpose of the prefabricated storage box, when the square panel and the connecting pipe are combined, a plurality of projections come into close contact with the inside of the connecting pipe to prevent the primary separation. On the other hand, when the finishing material is coupled to both ends of the connecting pipe, the protruding jaw formed on the edge of the square panel is drawn in and then caught on the outside of the finishing material, so that it has a solid fixing force without a separate fixing means (bolts, etc.) It is a useful invention that can have simplification of assembly and convenience in initial production.
