[0002] The construction site storage box is commonly used as a tool on the construction site, and is often used to store various tools, hardware and equipment. The existing box usually adopts heavy steel support and cannot be folded, so that the volume of transportation is large and the transportation cost is increased.

[0003] SUMMARY

[0004] The present application overcomes the problem of increased transportation cost due to the inability to fold the construction site storage box in the prior art, and provides a folding storage cabinet which can fold the construction site storage box during transportation, thereby reducing the transportation cost.

[0005] In order to solve the above technical problems, the present application adopts the following technical scheme: a folding storage cabinet, comprising: a bottom wall and a top wall, the bottom wall being hinged with a first side wall and a second side wall; the first side wall and the second side wall are both provided with two, and are oppositely arranged on both sides of the bottom wall; the second side wall is hinged with the top wall, and the second side wall comprises a plurality of hingedly connected side wall single plates; in the folded state, the plurality of side wall single plates are folded, and the first side wall and the second side wall are folded and stored between the top wall and the bottom wall around the hinge edge with the bottom wall.

[0006] When transportation is needed, the first side wall and the second side wall can be folded towards the bottom wall, so that the whole is in a folded state, and the volume of the folded whole is small, thereby reducing the space occupied by a single product during transportation and reducing the transportation cost; when it is needed to be unfolded, the top wall is directly pulled up, so that the second side wall is in a vertical state, and then the first side wall is unfolded to be in a vertical state, and the first side wall and the second side wall are fixedly connected through the connecting piece, so that the assembly of the whole structure is completed, and the assembly is convenient.

[0008] H2-H1>=D, so that when the first side wall and the bottom wall are in contact in the folded state, the first side wall can be located below H2, i.e. the first side wall can be located below the second edge, without affecting the folding of the second side wall, so that the volume of the whole after folding is smaller.

[0009] Preferably, the bottom of the bottom wall is provided with a plurality of seat sleeves and a plurality of detachable wheels, and the seat sleeves are arranged along the two sides of the bottom wall in the width direction.

[0010] The seat sleeves are arranged along the two sides of the bottom wall in the width direction, so that the two clamping arms of the forklift can pass through the seat sleeves on the two sides in the width direction respectively, so that the center of gravity can fall between the two clamping arms of the forklift during transfer, thereby improving the stability of the transfer and folding storage cabinet. The detachable wheels are arranged on the bottom wall, which can be detached during transportation, and placed in the seat sleeves or between the bottom wall and the top wall, thereby reducing the overall volume.

[0077] The technical solutions of the present application are further described below with specific embodiments and in conjunction with the drawings: Embodiment 1: Referring to FIGS. 1-10, a folding storage cabinet includes a bottom wall 1 and a top wall 2, the bottom wall 1 is hinged with a first side wall 3 and a second side wall 4; the first side wall 3 and the second side wall 4 are both provided with two, and are oppositely arranged on both sides of the bottom wall 1; the second side wall 4 is hinged with the top wall 2, and the second side wall 4 includes a plurality of side wall single plates 41 hinged with each other; in the folded state, the plurality of side wall single plates 41 are folded, and the first side wall 3 and the second side wall 4 are folded and stored between the top wall 2 and the bottom wall 1 around the hinge edge of the bottom wall 1.

[0078] In this embodiment, the bottom wall 1 and the first side wall 3, the second side wall 4 and the top wall 2 around the perimeter together form a box body, forming a storage space inside, the first side wall 3 and the second side wall 4 are both hinged with the bottom wall 1, so that the first side wall 3 and the second side wall 4 can be rotated around the side edge of the bottom wall 1 respectively, so that in the folding state, the first side wall 3 and the second side wall 4 can be folded towards the bottom wall 1 (as shown by the arrow in FIG. 1). The oppositely arranged second side wall 4 does not interfere with the folding effect in the folded state, and at the same time can have a certain height in the unfolded state, thereby increasing the use volume of the box body. Therefore, the second side wall 4 is provided as a plurality of side wall single plates 41 hinged with each other, so that in the unfolded state, the side wall single plates 41 can be unfolded to form a first side wall 3 with a relatively high height, thereby increasing the use volume of the cavity, and at the same time, in the folding state, the plurality of side wall single plates 41 can be folded with each other, so that the overall width of the folded second side wall 4 is only the width of a single side wall single plate 41, thereby enabling the two folded second side walls 4 to be distributed on both sides of the bottom wall 1, so that the overall does not interfere after folding.

[0079] When it is needed to use, the folded box body needs to be unfolded, since the top wall 2 is hinged with the second side wall 4, in the unfolding process, the top wall 2 can be directly pulled up, so that the second side wall 4 is in a vertical state perpendicular to the bottom wall 1, then the first side wall 3 is unfolded, so that the first side wall 3 is in a vertical state perpendicular to the bottom wall 1, then the part where the first side wall 3 and the second side wall 4 contact is fixed by a connecting piece, thereby completing the assembly of the box body.

[0080] Therefore, in the embodiment, when transportation is needed, the first side wall 3 and the second side wall 4 can be folded towards the bottom wall 1, so that the whole is in a folded state, and the volume of the folded whole is small, thereby reducing the space occupied by the single product during transportation, and further reducing the transportation cost; when unfolding is needed, the top wall 2 is directly pulled up, so that the second side wall 4 is in a vertical state, and then the first side wall 3 is unfolded to be in a vertical state, and the first side wall 3 and the second side wall 4 are fixedly connected through the connecting piece, so that the assembly of the whole structure is completed, and the assembly is convenient.

[0081] Embodiment 2: Referring to FIGS. 1-10, a folding storage cabinet includes a bottom wall 1 and a top wall 2, the bottom wall 1 is hingedly connected with a first side wall 3 and a second side wall 4; the first side wall 3 and the second side wall 4 are both provided with two, and are oppositely arranged on both sides of the bottom wall 1; the second side wall 4 is hingedly connected with the top wall 2, and the second side wall 4 includes a plurality of side wall single plates 41 hingedly connected with each other; in a folded state, the plurality of side wall single plates 41 are folded, and the first side wall 3 and the second side wall 4 are folded and stored between the top wall 2 and the bottom wall 1 around the hinge edge of the bottom wall 1.

[0082] The first side wall 3 is arranged at both ends of the length direction of the bottom wall 1, the second side wall 4 is arranged at both ends of the width direction of the bottom wall 1, and the length of the first side wall 3 in the horizontal direction is shorter than the length of the second side wall 4 in the horizontal direction.

[0083] The hinge edge of the first side wall 3 and the bottom wall 1 is defined as a first edge, the hinge edge of the second side wall 4 and the bottom wall 1 is defined as a second edge, the vertical height of the first edge from the bottom wall 1 is H1, the vertical height of the second edge from the bottom wall 1 is H2, H2 is greater than H1, the thickness of the first side wall 3 is D, and H2-H1≧D. Through the above arrangement, when the first side wall 3 and the bottom wall 1 are fitted in the folded state, the first side wall 3 can be located below H2 after folding, i.e. the first side wall 3 can be located below the second edge, without affecting the folding of the second side wall 4, so that the overall volume after folding is smaller.

[0084] In addition, as shown in FIG. 3, the first side wall 3 in the embodiment is a whole plate structure, therefore, in the folded state, after the first side wall 3 is fitted with the bottom wall 1, in order to prevent the two folded first side walls 3 from interfering with each other, the height of the first side wall 3 is H3, the length of the bottom wall 1 is L, and 2*H3≦L. Thus, after the first side wall 3 is folded, the two first side walls 3 can be respectively fitted on both sides of the length direction of the bottom wall 1.

[0085] It should be noted that in order to enable the second side wall 4 to be folded when several side wall panels 41 can be folded together. The second side wall 4 in this embodiment is formed by two side wall panels 41 hinged to each other, so that when folded, the two side wall panels can be folded together. Of course, the side wall panels 41 can also be provided in three (as shown in FIG. 10), four or the like according to actual conditions.

[0086] The first side wall 3 is provided as several side wall panels 41 hinged to each other, so that in the box state, the side wall panels 41 are unfolded to form a first side wall 3 with a relatively high height, ensuring the use volume of the folding storage cabinet in the unfolded state, and at the same time, when folded, several side wall panels 41 can be folded together, so that the overall width of the second side wall 4 after folding is only the width of a single side wall panel 41, thereby enabling the two first side walls 3 after folding to be distributed on both sides of the bottom wall 1, so that the two second side walls 4 do not interfere with each other in the folded state.

[0087] In order to facilitate the movement of the folding storage cabinet during use, and at the same time, to facilitate the transfer of the folding storage cabinet by instruments such as forklifts, clamping machines and the like. As shown in FIG. 2, a plurality of seat sleeves 5 and detachable rollers 6 are provided on the bottom of the bottom wall 1, and the seat sleeves 5 are arranged along the two sides of the width direction of the bottom wall 1.

[0088] The seat sleeves 5 and the rollers 6 in this embodiment are each provided with four. Therefore, on both sides of the width direction of the bottom wall 1, two seat sleeves 5 and rollers 6 are provided on each side.

[0089] The seat sleeves 5 can facilitate the passage of the clamping arms of the forklift through the seat sleeves 5, thereby eliminating the need to borrow a forklift support during the process of moving the folding storage cabinet, thereby improving the efficiency of transferring the folding storage cabinet. In addition, the seat sleeves 5 can also support the folding storage cabinet. Therefore, in order to improve the stability of the forklift in transferring the folding storage cabinet, the seat sleeves 5 are arranged along the two sides of the width direction of the bottom wall 1, so that the two clamping arms on the forklift can pass through the seat sleeves 5 on both sides of the width direction, so that the center of gravity can fall between the two clamping arms of the forklift during transfer, thereby improving the stability of the folding storage cabinet during transfer.

[0090] The detachable rollers 6 are provided on the bottom wall 1, which can be detached during transportation, and the rollers 6 can be placed in the seat sleeves 5 (as shown in FIG. 7) or between the bottom wall 1 and the top wall 2 (as shown in FIG. 8) or between the side wall panels 41 or the top wall 2 (as shown in FIG. 9), thereby reducing the overall volume; and can be installed on the bottom wall 1 during use, facilitating the movement of the folding storage cabinet during use. The rollers 6 can also be provided with a roller stop 61, which can be locked at any time as needed during use, thereby preventing the box from moving.

[0091] In one embodiment, the seat cover 5 comprises a first plate 51, the two ends of the first plate 51 are respectively provided with a second plate 52 and a third plate 53, and the roller 6 is detachably arranged at the bottom of the first plate 51. The top of the roller 6 is provided with a mounting plate 62, and the mounting plate 62 and the first plate 51 are fixedly connected by bolts, so that the roller 6 can be detachably connected with the first plate 51. The roller 6 can be directly connected with the bottom of the bottom wall 1 as the seat cover 5, and in this embodiment, the roller 6 is arranged at the bottom of the first plate 51, which makes the height of the bottom wall 1 the sum of the height of the roller 6 and the height of the seat cover 5, thereby increasing the overall height of the folding storage cabinet base. Because the environment of the construction site is harsh, and the ground is mostly uneven, by arranging the roller 6 at the bottom of the first plate 51, the height of the folding storage cabinet base can be increased, thereby improving the passing capacity of the folding storage cabinet on the construction site.

[0092] In order to improve the stability of the overall structure, the first plate 51 is arranged close to the side edge of the bottom wall 1 in the width direction, and the first plate 51 is arranged obliquely towards the side edge of the bottom wall 1 (as shown in FIG. 2). Since the seat cover 5 is arranged on both sides of the bottom wall 1 in the width direction, the first plate 51 on the seat cover 5 on both sides in the width direction forms a structure similar to "eight characters" on both sides of the bottom wall 1, thereby making the seat cover 5 on the bottom wall 1 play a stable supporting role for the folding storage cabinet, and improving the overall strength of the side wall.

[0093] In one embodiment, the top wall 2 and the bottom wall 1 have similar structures. The bottom wall 1 comprises a lower fixed frame 11 and a lower cover 12, and the lower cover 12 is fixedly connected with the lower fixed frame 11. The top wall 2 comprises an upper fixed frame 21 and an upper cover 22, and the side edge of one side of the upper cover 22 is hingedly connected with the side edge of one side of the upper fixed frame 21. The side wall where the upper cover 22 and the upper fixed frame 21 are hingedly connected is the upper cover hinge edge, so that the upper cover 22 can rotate around the upper cover hinge edge, thereby opening and closing the folding storage cabinet when needed.

[0094] The lower fixed frame 11 comprises two first wide strips 111 and two first long strips 112, and the two first wide strips 111 are arranged opposite to each other, and the two first long strips 112 are arranged opposite to each other. The first wide strip 111 is hingedly connected with the first side wall 3, and the first long strip 112 is hingedly connected with the second side wall 4. The height of the first long strip 112 is higher than the height of the first wide strip 111. When the first side wall 3 is in contact with the bottom wall 1 in the folded state, the upper end surface of the first side edge is lower than the upper end surface of the first long strip 112, and does not affect the folding of the second side wall 4.

[0095] The upper fixed frame 21 comprises two second wide strips 211 and two second long strips 212, the two second wide strips 211 are oppositely arranged, and the two second long strips 212 are also oppositely arranged. The two second long strips 212 are respectively hingedly connected with the top ends of the two second side walls 4. The height of the second long strip 212 is higher than that of the second wide strip 211; so that when in the unfolded state, the upper end part of the first side wall 3 is just located between the two second long strips 212, and the second long strip 212 limits the top of the first side wall 3, so that the unfolded box structure is more stable.

[0096] A support rod is arranged between the upper fixed frame 21 and the upper cover 22, and the support rod includes but is not limited to a hydraulic buffer rod 13. One end of the hydraulic buffer rod 13 is connected with the inner side wall of the upper fixed frame 21, and the other end of the hydraulic buffer rod 13 is connected with the upper cover 22.

The fixing pin 92 is fixedly arranged on the first wide strip 111 of the lower fixing frame 11, and the fixing pin 92 is also arranged outside the lower fixing frame 11. The end of the rotating piece 91 away from the second wide strip 211 is provided with the hook portion 911. When the box is in the folded state, the rotating piece 91 is rotated so that the hook portion 911 hooks the fixing pin 92. The length of the rotating piece 91 corresponds to the distance between the upper fixing frame 21 and the lower fixing frame 11 of the box in the folded state. The hook portion 911 hooks the fixing pin 92, so that the top wall 2 and the bottom wall 1 are fixed during transportation of the box, thereby reducing the relative displacement between the top wall 2 and the bottom wall 1 during transportation of the folded box, making the transportation and transportation of the folded box more stable; reducing the noise generated during movement, and at the same time, reducing the damage to the overall structure caused by bumps during transportation.

[0114] In addition, the circumferential direction of the side wall of the fixing pin 92 in this embodiment is provided with an inwardly recessed annular groove, so that the hook portion 911 can be more stable when hooking the fixing pin 92.

[0115] Of course, the rotating piece 91 and the first wide strip 111 of the lower fixed frame 11 can be rotatably connected, and the fixed pin 92 is fixedly arranged on the second wide strip 211 of the upper fixed frame 21.

[0116] In addition, the fixing structure can be arranged in two groups or four groups, and the two groups or four groups of fixing structures are symmetrically arranged on both sides of the length direction of the box body and play a fixing role on both ends of the length direction of the box body, thereby better fixing the box body in the folded state.

[0117] In the embodiment 1 or the embodiment 2 or the embodiment 3 or the embodiment 4 or the embodiment 5 or the embodiment 6, the first side wall 3 and the second side wall 4 are connected by a rivet. Although this connection makes the overall structure of the connected box body more firm, it is difficult to restore to the folded state again after being fixedly connected by the rivet. Therefore, in the present embodiment, a connecting structure is arranged between the first side wall 3 and the top wall 2 or between the first side wall 3 and the second side wall 4. When the box body is in the unfolded state, the connecting structure can temporarily fix the first side wall 3 and the top wall 2. When the box body needs to be folded again, the connecting structure can be opened to separate the first side wall 3 and the top wall 2, thereby facilitating the folding of the box body again.

[0118] The connecting structure in the present embodiment includes a connecting piece 93 and a locking piece 94, and the connecting piece 93 and the locking piece 94 are arranged on the top wall 2 and the first side wall 3, respectively. The locking piece 94 is provided with an open slot 941, and the connecting piece 93 is provided with a bent piece 931 at an end away from the rotation center. The connecting piece 93 is rotatably connected, and the connecting piece 93 and the open slot 941 are matched.

[0119] Specifically, the connecting structure in the present embodiment includes a connecting piece 93 rotatably arranged on the second wide strip 211 and a locking piece 94 arranged on the first side wall 3. The locking piece 94 is provided with an open slot 941, and the connecting piece 93 is provided with a bent piece 931 at an end away from the second wide strip 211. The bent piece 931 and the connecting piece 93 form a certain angle, and the angle between the bent piece 931 and the connecting piece 93 in the present embodiment is 90°. As shown in FIG. 12, when the box body is in the unfolded state, the connecting piece 93 is located in the open slot 941 (as shown by the solid line in FIG. 12). Through the cooperation of the open slot 941 and the connecting piece 93, the connecting piece 93 and the locking piece 94 are in a locked state, and the first side wall 3 and the upper fixed frame 21 are in a connected state.

[0120] When the box needs to be converted from the unfolded state to the folded state, the connecting piece 93 can be rotated to be separated from the opening slot 941 (as shown by the dotted line in FIG. 12), so that the locking state between the connecting piece 93 and the locking piece 94 can be released, the first side wall 3 and the second side wall 4 can be folded normally, and the box can return to the folded state.

[0121] In addition, the connecting piece 93 is arranged on the second wide strip 211, and the locking piece 94 is arranged on the first side wall 3. At this time, the locking piece 94 is below the connecting piece 93. When the box is in the unfolded state, the connecting piece 93 is in the opening slot 941, and at this time, the connecting piece 93 is in the vertical direction. That is, in this state, the connecting piece 93 is always kept in the vertical direction under the action of gravity, and the connecting piece 93 will not be separated from the opening slot 941 without human intervention during use, so that the box can always be in the unfolded state and will not affect normal use. Only when the box needs to be folded again, the connecting piece 93 is rotated by human intervention, the connecting piece 93 is separated from the opening slot 941, and at this time, the box can be folded. In addition, the connecting structure in the present application is arranged on the inner side of the box, that is, when the box is in the unfolded state, the connecting structure is arranged on the inner side of the box, so that the connecting piece 93 can be effectively prevented from being accidentally touched.

[0122] The above embodiments are only the preferred schemes of the present application, and do not limit the present application in any form. Other variants and modifications can be made without departing from the technical scheme of the claims.
