Abstract

The design of the present invention is that both inner end shafts of the plastic handles are inserted into the upper sides of both long side walls of the box so that the double outer side penetrates the shaft holes to catch the end projections of the shaft, and the plastic handles installed in the mandrel are rotated inwardly. Rectangular grooves are formed at the upper sides of both long side walls, and the inner side of the double outer side is formed with a shaft insertion hole into which both inner end shafts of the steel handle are inserted, and a steel handle provided with a mandrel installed in this shaft insertion hole to be rotated inward to be in contact with each other. Semi-circular grooves are formed at the top of the side wall, so plastic handles and steel handles can be selected and used in the same box depending on the application. Both sides of the bottom of the box correspond to the square grooves of the plastic handles and the semi-circular grooves of the steel handles. When the boxes are stacked up and down by forming inner and inner stripe band grooves The plastic handle and the steel handle selected according to the drawings are both inserted into the outer and inner rectangular band grooves at the bottom of the box so that both steel and plastic handles can be used to safely stack several boxes up and down.

Description

A conveyance box capable of using both of iron and plastic grip bars}

The present invention is a steel handle and a plastic handle that can be used both by selecting a handle for installing a mandrel to install a mandrel to be rotated inward and outward on both sides of the upper side of the long side wall in the transport box It's all about carrying boxes.

In general, when transporting empty boxes in a transport box, the upper box is wider and the lower part is narrower so that the four walls are inclined surfaces so that the upper box can be nested inside the lower box in order to minimize the volume. In order to prevent damage, the steel handles are placed on both sides of the box so that they can be rotated inwards and outwards, and the steel handles are rotated inwards so that the upper box is placed on the top of the steel handles. Therefore, when exposed to salinity or chemicals, the steel handle cannot be used and should be replaced with a plastic handle. If the two inner end shafts are bent in the shape and are slightly enlarged and inserted into the shaft holes on both sides of the box, the elasticity of the steel is returned to its original position and the shaft is kept in the fitted state. Since it is easily removed from the shaft hole, a protrusion is formed at the ends of both inner end shafts and the end protrusions of the inner end shafts are pushed into the shaft hole so that the end protrusions are not caught in the shaft hole. According to the shaft structure of the box is changed according to the use of steel and plastic handles, even in the same box there was a closed end to manufacture the box separately.

In the present invention, such a closed end is improved, and both inner end shafts of the plastic handle bars are inserted at both upper sides of the long side walls of the box so that the double outer side penetrates the shaft holes to which the end ends of the shafts are held, and the plastic handles installed in the mandrel are Rectangle grooves are formed on the upper sides of the two long side walls that are rotated inward, respectively.Inwardly, the shaft insertion hole into which the shafts of both ends of the steel handle are inserted and the steel handles installed in the mandrel in the shaft insertion hole are rotated inward. Semi-circular grooves are formed at the top of both long side walls that move and contact each other. Depending on the application, plastic handles and steel handles can be selected and used in the same box. Both sides of the box have rectangular grooves and steel Outside and inside square band grooves are formed to correspond to the semi-circular grooves of the handle. When the boxes are stacked up and down, plastic handles and steel handles, which are selected according to the use, are both inserted from the bottom of the box into the inner and inner rectangular band grooves, so that multiple boxes can be safely stacked up and down according to the drawing. It will be described in detail as follows.

12: shaft insertion hole 13: square groove 14: semi-circular groove

15,16: Outer, inner rectangular band groove 17: Outward protrusion

20: plastic handle 21: inner end shaft 21a: end projection

30: steel handle 31: inner end shaft

Double lateral side 11 through which both inner end shafts 21 of the plastic handle 20 are inserted into the upper sides of both long side walls of the box to penetrate the shaft holes 11a to which the end protrusions 21a of the shaft 21 are to be caught. ) And the plastic handle 20 installed in the mandrel in the shaft hole 11a are rotated inward to form rectangular grooves 13 on the upper sides of the long side walls which are in contact with each other. Both long side walls of which the shaft insertion hole 12 into which both inner end shafts 31 of the handle bar 30 are inserted and the steel handle bar 30 installed in the mandrel in the shaft insertion hole 12 are rotated inward to be in contact with each other. Semi-circular grooves 14 are formed on the upper sides, and both sides of the bottom of the box correspond to the square grooves 13 of the plastic handle 20 and the semi-circular grooves 14 of the inward steel handle 30, Inner square strip grooves 15 and 16 are formed respectively, and both outwardly facing middle walls of both long side walls are stepped from top to bottom. It was made to protrude to the exit wall 17.

When explaining the state of use of the present invention carrying box having such a configuration, the double outer side 11 penetrated through the shaft hole 11a that can be installed in the shaft of the plastic handle (20) on both sides of the upper side wall of the box Since the shaft insertion hole 12, which can be installed to the mandrel of the steel handlebar 30 to the shaft inwardly formed, respectively, when the plastic handlebar 20 is installed in the carrying box according to the purpose, the plastic handlebar 20 When the end projections 21a of the shaft 21 are inserted into the shaft holes 11a penetrated by the double inner side walls 11 of both long side walls of the box with both inner end shafts 21) The end projection 21a of the shaft 21 is a shaft hole in a state in which both inner end shafts 21 of the weak plastic handle 20 are inserted into the shaft hole 11a of the box double outer bag 11. 11a) the plastic handle (20) caught in the interior can be easily removed from the shaft hole (11a) When connecting the steel handle according to the purpose, the inner side shaft 31 of the steel handle 30 is slightly enlarged elastically and inserted into the shaft insertion hole 12 formed on the inward side of the double outer stand 11. When the inner end shaft 31 is circumferentially returned by the elastic strength of the steel is not easily separated from the shaft insertion hole (12).

When the plastic rod and the steel handle bar installed in this way to rotate inwardly, the plastic handle bar 20 is in the rectangular groove 13 of the top of both long side walls, the steel handle bar 30 in the semi-circular groove 14, respectively When the other box is stacked on top of the box, the rectangular band grooves 15 and 16 formed on both sides of the bottom of the upper box and the inside of the box are inserted into the outer rectangular band groove 15 when the plastic handle 20 is used. , When using the steel handle 30 is a plastic handle and the steel handle is inserted into the inner square band groove 16 is placed there will be able to safely stack several boxes up and down.
