Description

Bonding Structure of Pallet Stacked Body

The present invention relates to a coupling structure of the pallet stack, and more particularly, the pallet stack, which can be detachably coupled to the upper surface of the pallet, can be folded to the receiving space side for accommodating the article through the left and right side walls which can be rotated, It is possible to fold the left and right side walls more easily by using, and relates to a coupling structure of the pallet stack that can more firmly maintain the shape of the unfolded receiving space.

In general, the box is so essential that there is no place that is not used in real life, its use is very diverse, such as when storing and storing the goods at home, industrial sites or agricultural sites. Such boxes are made of various materials such as paper, wood, plastic, etc. due to its convenience and various uses.

On the other hand, when manufactured from wood or plastic, it has the advantage of being longer than the paper box, which has a long lifespan.However, the box itself is hard when the box is not used (it is not stored in the box) because of its rigid and bulky appearance. It takes up a lot of space when it is stored separately, so it is difficult to use efficient space.

As a technique related to a box including a foldable main wall element that can be folded as needed to solve the above problems, the prior art domestic registered utility model No. 0 021 021 has a bottom plate, a top member located on the top of the bottom plate, the top member And upper and lower fixing protrusions rotatably inserted into the first and second fixing grooves of the lower plate and the lower plate, respectively. A portable folding basket is presented.

But. In the prior art, since the foldable first plate and the second plate of the foldable side plate are configured up and down, the user can easily fold when the user applies downward force, but the foldable side plates fixed for storing the goods therein have a good external force. There is a fear that it cannot endure and can easily be folded during use.

The present invention has been made to solve the above problems, it is easy to fold and fold out of the box, as well as to maintain a more firm shape of the unfolded accommodating space to prevent damage to the items stored in the box. It is an object of the present invention to provide a bonding structure of a pallet stack.

On the other hand, the object of the present invention is not limited to the above-mentioned object, other objects that are not mentioned will be clearly understood from the following description.

Coupling structure of the pallet stack according to the present invention for achieving the above object consists of a pair of front and rear partitions and a pair of left and right side walls hinged to the front and rear partitions forming a pallet stack to accommodate the article is received. In the coupling structure of the left and right side wall and the left panel including a left hinge portion formed on the left side and protruding on one side and a left through hole formed in the vertical direction through one side of the left hinge portion, the left and right The right panel includes a right hinge portion formed on the right side of the side wall and cut out on the right side thereof, and a right through hole formed in a vertical direction through one side of the right hinge portion, and inserted into and coupled to the left and right through holes, respectively. A pair of hinge shafts for rotating the left panel and the right panel and a pair of the hinge shafts, respectively. The combined characterized in that it comprises a fixing unit for fixing the panel between the left and a pair to enter into the right side panel of the fastening hole fastening is formed through in the vertical direction from the surface unit and the fastening unit and the left and right hinge.

In addition, the fixing unit is a pair of first fixing protrusions formed in the diagonal direction spaced around the fastening hole formed in the fastening unit, a pair formed in a diagonal direction spaced around the other fastening hole formed in the fastening unit. A second fixing protrusion of the pair, a pair of first fixing grooves formed in an arc shape around the left through hole formed in the left panel to guide and couple the first fixing protrusion, and the right through hole formed in the right panel; It is formed in an arc shape around the ball, characterized in that it comprises a pair of second fixing grooves for guiding and engaging the second fixing projections.

In addition, the fixing unit is a pair of third fixing projections formed in the diagonal direction spaced around the left through-hole formed in the left panel, and are formed spaced in the diagonal direction around the right through-hole formed in the right panel. A pair of fourth fixing protrusions, a pair of third fixing grooves formed in an arc shape around the coupling hole formed in the fastening unit to guide and couple the third fixing protrusions, and other fastenings formed in the fastening unit It is characterized in that it comprises a pair of fourth fixing grooves formed in an arc shape around the ball to guide and couple the fourth fixing projections.

By the means for solving the above problems, since the coupling structure of the pallet stack of the present invention includes a fixing unit consisting of a first fixing groove and a second fixing groove coupled to the first fixing protrusion and the second fixing protrusion, respectively, the fastening unit and Not only can be firmly fixed between the left and right hinge portion, there is an effect that can easily be folded to the left and right panels.
