In the stacked storage box according to the present invention, as shown in FIG. 1, a plurality of unit storage boxes 1 are stacked in multiple stages, but adjacent unit storage boxes 1 are physically bonded to each other to form a stacked form of the unit storage box 1 Can become even more solid.

To this end, each of the plurality of unit storage boxes 1 has a large housing shape, and an upper locking jaw 110 is formed on the upper surface, and the main body part 100 having a sliding groove 120 formed on the lower surface thereof, and the upper part of the body part 100 A first sliding protrusion 221 which is rotatably mounted on the upper locking protrusion 110 and a second sliding protrusion 222 inserted into the sliding groove 120 of the main body 100 stacked thereon It may be defined as including the handle portion 200 each formed,

At this time, when the first sliding protrusion 221 and the second sliding protrusion 222 of the handle part 200 are inserted into the upper locking protrusion 110 and the sliding groove 120 of the body part 100 stacked on the upper part, respectively, The rotation of the handle part 200 is fixed and adjacent unit storage boxes 1 have a structure in which adjacent unit storage boxes 1 are bound to each other, so that the stacked unit storage boxes 1 have a strong binding force to each other.

More specifically, the front of the main body 100 is opened so that items can be stored or taken out even when the unit storage boxes 1 are stacked on each other. In addition, the upper surface may be opened if necessary, and a cover is mounted to open and close such an open portion. A cover for opening and closing the front surface of the main body 100 will be described later.

The first sliding protrusion 221 is bent in a shape so that the first sliding protrusion 221 is slid to enter the upper locking jaw 110 without difficulty, but the first sliding protrusion 221 slid on the upper locking jaw 110 falls toward the top. Do not go out. In addition, the sliding groove 120 is inserted into the sliding groove 120 by forming a release bump 121 in the lower portion so as to have a shape similar to that of the upper hooking protrusion 110, and then sliding to the top of the release bump 121 2 The sliding protrusion 222 is made to form a shape so as not to escape downward by the departure bump 121.

On the upper part of the body part 100, a hinge base 170 for rotational installation of the handle part 200, which will be described later, is formed, and the hinge base 170 is formed in a pair at the left and right ends of the body part 100. It is preferable to be provided.

Next, the handle part 200 plays a role of physically binding the stacked unit storage boxes 1 in addition to being used as a holding means for lifting the unit storage box 1.

To this end, the handle part 200 includes a hinge socket 210 rotatably installed on the hinge base 170, the first sliding protrusion 221 and the second sliding protrusion 222, and the hinge socket ( In 210), the first sliding protrusion 221 and the second sliding protrusion 222 are connected to the upper locking protrusion 110 and the sliding groove 120 according to the in-and-out operation in the hinge socket 210. It may be defined as including a key member 220 that slides toward.

First, the hinge socket 210 has an inner space capable of accommodating the end of the key member 220 as shown in FIG. 4, and the end of the key member 220 enters and enters the inner space. In addition, a decomposition bump 121 may be formed at the entrance of the inner space, and an end of the key member 220 is caught by the decomposition bump 121 to prevent complete separation from the inner space.

The key member 220 is vertically bent multiple times, and both ends are connected to a pair of hinge sockets 210, respectively. Further, a gripper 223 into which a user's finger can be inserted may be formed in the center.

The first sliding protrusion 221 and the second sliding protrusion 222 are provided as a pair on both left and right sides, and the first sliding protrusion 221 is toward the inside of the key member 220, and the second sliding protrusion ( Each 222 has a direction protruding toward the outside of the key member 220. In addition, locking protrusions 226 are formed at both ends of the key member 220 to be caught by the decomposition bump 121.

The operation of the handle part 200 is a key so that the key member 220 is inserted into the hinge socket 210 while the handle part 200 is rotated in contact with the upper surface of the body part 100 as shown in FIG. 5. When the member 220 is slid in the direction of the hinge socket 210 so that the first sliding protrusion 221 is caught by the upper engaging jaw 110, the rotational motion of the handle part 200 itself may be restricted. .

In this case, an auxiliary locking jaw 180 is formed at the rear of the upper surface of the main body 100 to assist the operation of the upper locking jaw 110 and the first sliding projection 221 and sliding toward the auxiliary locking jaw 180 A third sliding protrusion 224 may be formed in the center of the key member 220.

When the operation of the handle part 200 is performed in a state in which the unit storage boxes 1 are stacked in multiple stages, the adjacent unit storage boxes 1 act as parts that can be physically bonded to each other.

In other words, when another unit storage box 1 is stacked on the top of the unit storage box 1 as shown in FIG. 6, the other main body 100 ′ is mounted on the top of the main body 100 The second sliding protrusion 222 is naturally inserted into the sliding groove 120 ′ of the part 100 ′, and the second sliding protrusion 222 is inserted into the sliding groove 120 ′ of the other body part 100 ′ When the key member 220 is slid in the direction of the hinge socket 210 so that the key member 220 is inserted into the hinge socket 210, the second sliding protrusion 222 is caught in the sliding groove 120'. 1 The sliding protrusion 221 is engaged in the upper locking jaw 110 and the second sliding protrusion 222 is engaged in the sliding groove 120 ′ of the other main body 100 ′, so adjacent unit storage boxes 1 A bond can be achieved.

On the contrary, when the key member 220 is pulled out of the hinge socket 210, the first sliding protrusion 221 and the second sliding protrusion 222 slide with the upper locking projection 110, respectively The physical binding of the adjacent unit storage box 1 may be released while exiting the groove 120, and the key member 220 is retracted from the hinge socket 210 so that this operation is not easily generated except for arbitrary manipulation by the user. It is necessary to remain in a state of being.

If the key member 220 is easily withdrawn from the hinge socket 210, the binding of the adjacent unit storage box 1 is released and there is a concern that the multi-layered unit storage box 1 may be easily overturned.

In order to prevent this, the upper surface of the main body 100 is locked so that the key member 220 is not arbitrarily withdrawn from the hinge socket 210 while adjacent unit storage boxes 1 are bound to each other as shown in FIG. The piece 150 is formed, and the key member 220 is formed with a locking protrusion 225 that is engaged with the locking piece 150.

The locking piece 150 and the locking protrusion 225 protrude in a direction opposite to each other, and the locking protrusion 225 rides on the locking piece 150 while the key member 220 is inserted into the hinge socket 210. Going over, the locking protrusion 225 and the locking piece 150 are engaged with each other. In this state, when the traction force is not provided to the key member 220, the key member 220 is not pulled out from the hinge socket 210 due to the locking action of the locking piece 150 and the locking protrusion 225. ) Is not easily moved, and if the user arbitrarily pulls the key member 220 to withdraw the key member 220 from the hinge socket 210, the locking protrusion 225 rides the locking piece 150 and slides over the first sliding The protrusion 221 and the second sliding protrusion 222 come out from the upper locking jaw 110 and the sliding groove 120, respectively. In this case, the physical binding between adjacent unit storage boxes 1 is released.

In summary, in the stacked storage box according to the present invention, when the unit storage box 1 is stacked in multiple stages, the unit storage box 1 is connected to each other in a multi-stage manner by bonding adjacent unit storage boxes 1 to each other using the handle part 200. Even in a stacked state, the unit storage boxes 1 are not easily separated from each other, providing the advantage of excellent volumetric safety.

On the other hand, the stacked storage box according to the present invention is rotatably installed on the open front upper portion of the body portion 100, the first fixing protrusion inserted into the first front groove 160 formed in the upper front of the body portion 100 It is rotatably installed under the open front of the first cover 300 and the main body 100 with 310 formed, and inserted into a second front groove (not shown) formed below the front of the main body 100 It may further include a second cover 400 in which the second fixing protrusion 410 is formed.

The first cover 300 is operated to open and close the open front upper part of the main body part 100, and the second cover 400 opens and closes the open front lower part of the main body part 100, respectively. 2 If only one of the covers 400 is individually operated, a part of the front surface of the main body 100 can be opened and closed individually.

At this time, as shown in FIG. 7, the first fixing protrusion 310 takes a shape that is inclined outward toward the end, and in this case, the first fixing protrusion 310 does not easily come off from the first front groove 160. The first cover 300 is not easily opened in a state in which the front upper portion of the main body 100 is closed.

On the other hand, as shown in FIG. 8, a rotation limiting protrusion 171 may be formed in the upper center of the hinge base 170, and a rotation limiting protrusion that is caught by the rotation limiting protrusion 171 in the hinge socket 210 ( 212) can be formed.

The rotation limiting jaw 171 and the rotation limiting protrusion 212 are for limiting the rotational motion of the excessive grip part 200, and the grip part 200 rotates freely in a range of approximately 180° from the top of the body part 100 It is possible, but the rotation of the handle portion 200 is limited within the angular range of 90° by the rotation limiting jaw 171 and the rotation limiting protrusion 212. That is, when the user lifts the handle part 200 by hand and uses one unit storage box 1 individually, the main body part 100 is used as a safety device to prevent excessive shaking in the handle part 200.

In summary, the stacked storage box according to the present invention uses the handle part 200 as a means for physically binding the adjacent unit storage box 1, so that the adjacent unit storage boxes 1 stacked in multiple stages can be firmly bonded to each other. Accordingly, there is an effect of ensuring volume stability even in a state in which the unit storage box 1 is stacked in multiple stages up to a high position by maintaining the stacked form of the unit storage box 1 firmly.
