Description

Box corner stapler and box corner fixing method using the stapler

The present invention relates to a box corner stapler and a box corner fixing method using the stapler, and more particularly, to fix the corner portion of a conventional box, but without forming a separate overlapping portion, the end of each facing surface is It relates to a technology that allows them to be positioned so as to be in contact with each other so that they can be firmly fixed without forming a gap therebetween.

In general, a stapler refers to a device that binds multiple sheets of paper into a single bundle using a diguin-shaped stylus.

On the other hand, in the case of such a conventional stapler, the lower plate constituting the support plate for bending the stapler's iron needle at one end of the upper end, and one end is hingedly coupled to the other side where the support plate of the lower plate is configured to rotate, and there are a number of horizontal directions inside. Consists of an iron needle storage part forming an insertion space into which the iron needles are inserted, and a top plate that is connected to the hinge and surrounds the iron needle storage part so that the iron needles are pulled out when one side is selectively pressed. It is configured to pick up and fix.

However, in the case of such a conventional stapler, in general, only the role of stacking paper is performed.In the case of not only paper but also an assembled box, the overlapped part can be easily overlapped and fixed with a stapler, but the corner part of the box is made of synthetic resin. The bolt-nuts of the box are coupled to each other so that they can be fixed, and the ends of the boxes are in contact with each other to fix the corners of the box, but the protruding parts are overlapped with each other to form a hole between the bolts- It is fixed using a nut.

On the other hand, such a conventional prefabricated box not only has a number of inconvenient points in its assembly, but if any one of the bolt-nuts is damaged, it is not possible to purchase only the bolt and nut separately, so the economic efficiency of disposing the entire prefab box is very high. There was a problem that it was impossible to use the assembled box itself when the bolt-nut was missing or defective when the assembled box was purchased online or offline.

Accordingly, a separate corner reinforcement hole is provided in the prefabricated box to reinforce the corner and then fix it, but this is a structure that is impossible to apply to all prefabricated boxes.

First of all, looking at the conventional technologies,

Registration No. 10-1508527 (Special) A receiving part in which a plurality of iron cores are inserted, a pressing part that is hinge-connected to the receiving part to discharge the iron core from the receiving part by pressing, and the receiving part and one side are hinged In a stapler consisting of a supporting part that connects and is discharged in conjunction with a pressing part to bend the paper by passing through the paper, the alignment module bent at a right angle between the supporting part and the receiving part is positioned, the alignment module It is elastically supported on the support so that the paper is arranged at the same angle on the stapler, but the alignment module has a fixing bar having a groove therein, and the upper part of the support bar vertically installed on the support is coupled to the groove and vertically It is a technology related to a stapler in which the alignment module is configured to be able to move up and down flexibly, consisting of a spring installed between the outer periphery of the support bar and the groove and the upper support bar.

Publication No. 10-2010-0072120 (Special) In a stapler, which is a machine that stitches multiple sheets of paper into one, a vertical fixing frame holding a vertical surface of the binding paper uniformly on one side of an upper rotation axis of the pressing plate and binding inside the vertical fixing frame A 45-degree corner fixing frame is formed to hold the corners of the paper, and a natural slope is formed from the opposite side of the rotation axis to the bent part of the iron pin.
