In the box, the hollow hole on the inner surface of the recess is formed with an even number of protrusions, and support protrusions are formed at both ends of the upper surface of the handle contacting the inner surface, and an inner recess is formed with two protrusions corresponding to the even numbered protrusions. When loading, the bottom recess of the upper box is in contact with the upper part of the handle of the lower box, and both side walls are caught by the support protrusion, and the even numbered protrusions on the inner surface of the recess are recessed into the recesses of the upper part of the handle, so The inner surface and upper surface of the handle of the lower box are irregularities, and the whole surface is combined so that several boxes The packaging box designed to prevent the swing of the upper load box to prevent a fluctuation in the vehicle during transport

Description

Transport box to prevent rocking of the upper loading box {A conveyance box that is capable of preventing the rocking of upper loading box}

The present invention relates to a transport box that can prevent the shaking of the upper stacking box to be loaded to the top of the handle when loading the transport box up and down.

Conventionally, the handles in which the shafts of both inner ends are coupled to the shaft hole of the box to enable rotational movement inward and outward from both sides of the upper side of the box are placed in the box, and several boxes are loaded up and down to carry and store Rotate inward to the inner top of the box's long side wall, and when the top box is placed, the bottom part of the short side wall of the upper box is bent by bending down the middle part of the handle so that the top box can be settled without being shaken during transportation. However, due to the bending of the handle, the manufacturing cost of the handle increases, and the curved portion becomes a weak part of the handle.

In the present invention, in order to compensate for this drawback, both shafts of the inner side of the handle are coupled to the shaft holes on both sides of the upper part of the box, so that the handle is rotated inward and outward, and the handles placed inward on the entire ribs on the bottom of the box are inward. In the carrying box formed with recesses, an even number of protrusions are formed on the inner surface of the recess, and support protrusions are formed on both sides of the upper surface of the handle, and two protrusions correspond to the even protrusions on the inner upper surface thereof. In the case of box loading, the bottom recess of the upper box is in contact with the upper part of the handle of the lower box, and both side walls are caught by the support protrusion, and the even protrusions on the inner surface of the recess are two recesses in the upper part of the handle The inner surface of the recess of the upper box and the upper surface of the handle of the lower box When the surface is combined with a loading box multiple described in detail based on the drawings that are designed to prevent the swing during transport in a vehicle as follows.

Explanation of symbols for important parts of the drawings

1: groove 10: handle 11: recess

12: support protrusion 20: recessed portion 21: protrusion

21a: strip groove 22: support rib

Both ends of the handle 10 are coupled to the shaft holes on both sides of the upper box so that the handle 10 is rotated inwards and outwards, and the handles located inward when the box is loaded on both sides of the entire rib on the bottom of the box. In a well-known transport box in which the recesses 20 are formed, the protrusions 21 are formed in even numbers on the inner surface of the recesses 20 at an even number, and support protrusions are provided at both ends of the upper surface of the handle 10 in contact with them. (12), on the inner upper surface thereof is formed an indentation (11) into which two projections (21) are embedded so as to correspond with an even number of projections (21), and several support ribs (22) outward of the entire rib necker on the bottom of the box. (1) is a groove that is embedded in both sides of the upper side of the long side wall when the handle bar is rotated inward.

In addition, a strip groove 21a may be formed in the center of the protrusion 21 of the recess 20 in the longitudinal direction to form the protrusion 21 as an edge protrusion.

When the present invention has a structure described above, the contents are contained in the box, and the handles 10 on the upper sides of the box are rotated inward to move inward into the grooves 1 on both sides of the upper side wall of the box, and then the upper part of the box. When the other box is placed, the handle 10 of the lower box is placed in both recesses 20 of the bottom of the upper box so that the upper box is loaded up and down on the upper box of the lower box. The bottom recessed portion 20 of the upper box is in contact with the upper portion of the handle, and the bottom portion of both side walls of the upper box is caught by the support protrusions 12 at both ends of the upper surface of the handle 10, and an even number is formed on the inner surface of the recess 20. The protrusions 21 are recessed portions 11 formed on the upper surface of the handle box 10 of the lower box, and the protrusions 21 are recessed by two, so that the inner surface of the recess 20 of the upper box and the handle of the lower box ( 10) The upper surface is uneven, so the whole surface The support ribs 22, which are combined and formed outward of the entire rib necker on the bottom of the box, support the inner wall of the bottom wall of the lower box so that multiple boxes can be loaded and moved up and down without shaking. The load will remain intact.

Claims (3)
