Description

Technical Field

[0001] The present invention belongs to the technical field of storage containers, and in particular relates to a combined storage box that is convenient for stacking. Background Art

[0002] Storage boxes are containers used to store items. When multiple storage boxes are stacked, some storage boxes consist of an outer box and an inner box to facilitate access. Items can be accessed by pulling out the inner box.

[0003] However, existing storage boxes only rely on gravity for fixation, or achieve stacking through the combination of protrusions and grooves, but lack an automatic locking mechanism. High-rise storage boxes are easily tipped over by external forces. There is a risk of horizontal displacement between the upper and lower boxes after stacking, and the inner box lacks a stable and convenient locking method. The storage boxes have certain defects in stacking stability and operational convenience. Summary of the Invention

[0004] In order to solve the defects of existing storage boxes in terms of stacking stability and operational convenience, an object of the present invention is to provide a combined storage box that is easy to stack.

[0005] The technical solution is as follows: A combined storage box that is easy to stack, including an outer box and an inner box. The outer box is open on one side, and a sliding inner box is provided inside the outer box. Limit blocks are connected to the four corners of the top of the outer box, and limit holes for the limit blocks to extend into are provided at the four corners of the bottom of the outer box. The inner box is composed of a bottom plate, front and rear side plates, a left plate, a right plate and an inner plate. The bottom surfaces of the left plate and the right plate are lower than the bottom plate; two sliding rods are provided on the side of the right plate, and square holes for the rods to pass through are provided on the front and rear side plates. Sockets for the rods to pass through are provided on the outer box. When the inner box is pushed in, the rods, square holes and sockets are aligned.

[0006] More preferably, two limiting strips are connected inside the outer box.

[0007] More preferably, the combined storage box that is easy to stack also includes a rotating disk, a protrusion, a fixed block, a rotating rod and a pull ring. A circular hole is opened in the center of the right side plate, and the right side plate is rotatably connected to the rotating disk at the circular hole. The rotating disk has two centrally symmetrical arc grooves, and the arc grooves are divided into a proximal end close to the center of the rotating disk and a distal end away from the center of the rotating disk. The ends of the two insertion rods that are close to each other are rotatably connected to the protrusions, and the two protrusions are respectively located in the two arc grooves. The rotating rotating disk causes the two protrusions to move in opposite directions through the arc groove. The rotating disk is connected to the fixed block, the fixed block is rotatably connected to the rotating rod, and the rotating rod is connected to the pull ring.

[0008] More preferably, the combined storage box that is easy to stack also includes a connecting block and a limit rod. Two pairs of connecting blocks are connected to the bottom of the outer box. The connecting blocks are each provided with a sliding limit rod. The limit blocks are each provided with a slot for the limit rod to extend into on one side close to the limit rod. When two outer boxes are stacked, the limit block on the top of the lower outer box passes through the limit hole at the bottom of the upper outer box, and the limit rod of the upper outer box slides and extends into the slot.

[0009] More preferably, the top of each limiting block has a slope.

[0010] More preferably, the combined storage box for easy stacking also includes a connecting block 2, a translation rod, a rotating block and an extrusion plate. Two connecting blocks 2 are connected to the bottom of the outer box. The connecting blocks 2 are each provided with a sliding translation rod. An elastic member is connected between the translation rod and the connecting block 2. A rotating block is rotatably connected between the end of each pair of limit rods that is close to each other and the translation rod on the same side. An extrusion plate is connected to the bottom of the bottom plate, and the front two sides of the end of the extrusion plate have inclined surfaces 2 for extruding the translation rod.

[0011] More preferably, the combined storage box that is easy to stack also includes a storage frame, a partition plate and a baffle. The storage frame is placed inside the inner box, a through hole is opened on the top of the storage frame, the storage frame is connected to the partition plate, and the partition plate is connected to the baffle.

[0012] More preferably, the combined storage box for easy stacking further comprises a rotating plate, and embedding holes are provided on both sides of the outer box, and the outer box is rotatably connected to the rotating plate at the embedding holes.

[0013] The beneficial effects of the present invention are as follows: 1. Place the outer box on top of another outer box, pass the limiting block through the limiting hole, place the items in the inner box, push the inner box into the outer box, and the extrusion plate squeezes the translation rod through the second inclined surface. Under the action of the rotating block, the limiting rod is inserted into the card slot, which can make the position of the stacked outer boxes relatively fixed, realize automatic locking of the outer boxes, reduce the risk of outer boxes tipping over during stacking, and improve stacking stability and operational convenience.

[0014] 2. When the inner box is pushed into the outer box, the pull ring drives the rotating disk to rotate, and the rotating disk pushes the protrusion through the arc groove, driving the insertion rod to slide and pass through the square hole. The insertion rod extends into the socket, so that the positions of the inner box and the outer box are relatively fixed through the cooperation of the insertion rod and the socket.

[0015] 3. When the inner box is pulled out, pull up the storage frame and place the items on the partition board. The baffle blocks the items and prevents them from sliding off the partition board, thereby classifying and storing the items and improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Embodiment 1: A modular storage box that is easy to stack, such as Figures 1-6As shown, it includes an outer box 1, an inner box 2, a limit block 3 and an insertion rod 4. The outer box 1 has an opening on the right side, and a sliding inner box 2 is provided inside the outer box 1. The inner box 2 has two states: pulling out and pushing in. The four corners of the top of the outer box 1 are fixedly connected to the limit blocks 3. The four corners of the bottom of the outer box 1 are provided with limit holes 30 for the limit blocks 3 to extend into. The tops of the limit blocks 3 have a slope 32. The inner box 2 is composed of a bottom plate 21, front and rear side plates 22, a left side plate 23, a right side plate 24 and an inner side plate 25. The two front and rear side plates 22 are respectively connected to the front and rear sides of the bottom plate 21, the left side plate 23 is connected to the left side of the two front and rear side plates 22, and the right side plate 24 is connected to the right side of the two front and rear side plates 22. The inner side plate 25 is connected between the two front and rear side plates 22, and the bottom surfaces of the left side plate 23 and the right side plate 24 are lower than the bottom plate 21; two insertion rods 4 that slide back and forth are provided on the left side of the right side plate 24, and square holes 401 for the insertion rods 4 to pass through are opened on the right parts of the front and rear side plates 22, and insertion holes 402 for the insertion rods 4 to pass through are opened on the right parts of the front and rear sides of the outer box 1. When the inner box 2 is pushed in, the insertion rods 4, square holes 401 and insertion holes 402 are aligned in the front and rear direction; two front and rear symmetrical limit strips 10 are fixedly connected to the right side of the inside of the outer box 1. When the inner box 2 is pulled out, the right side of the left side plate 23 will contact the left side of the limit strip 10, thereby limiting the pull-out position of the inner box 2 by the limit strip 10.

[0029] like Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, the combined storage box that is easy to stack also includes a rotating disk 41, a protrusion 43, a fixed block 44, a rotating rod 45 and a pull ring 46. A circular hole is opened in the center of the right side plate 24, and the right side plate 24 is rotatably connected to the rotating disk 41 at the circular hole. Two centrally symmetrical arcuate grooves 42 are opened on the left side of the rotating disk 41. The arcuate groove 42 is divided into a proximal end close to the center of the rotating disk 41 and a distal end away from the center of the rotating disk 41. The ends of the two insertion rods 4 that are close to each other are rotatably connected to the protrusions 43, and the two protrusions 43 are respectively located at the proximal ends of the two arcuate grooves 42. The rotating rotating disk 41 causes the two protrusions 43 to move in opposite directions through the arcuate groove 42. The right side of the rotating disk 41 is fixedly connected to the fixed block 44, and the rotating rod 45 is rotatably connected to the fixed block 44, and the rotating rod 45 is fixedly connected to the pull ring 46.

[0030] like Figure 3 、 Figure 5 and Figure 6 As shown, the combined storage box that is easy to stack also includes a connecting block 5 and a limit rod 6. Two pairs of connecting blocks 5 are fixedly connected to the bottom of the outer box 1. The connecting blocks 5 are each provided with a limit rod 6 that slides left and right. The right side of the two limit blocks 3 on the left and the left side of the two limit blocks 3 on the right are each provided with a slot 31 for the limit rod 6 to extend into. When the two outer boxes 1 are stacked, the limit block 3 on the top of the lower outer box 1 passes through the limit hole 30 at the bottom of the upper outer box 1, and the limit rod 6 of the upper outer box 1 slides and extends into the slot 31.

[0031] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 9 and Figure 10 As shown, the combined storage box that is easy to stack also includes a connecting block 2 61, a translation rod 62, a rotating block 63 and an extrusion plate 64. The inner bottom of the outer box 1 is fixedly connected to two connecting blocks 2 61. The connecting blocks 2 61 are each provided with a translation rod 62 that slides back and forth. The translation rod 62 is L-shaped. An elastic member is fixedly connected between the translation rod 62 and the connecting block 2 61. The elastic member is a return spring. A rotating block 63 is rotatably connected between the end of each pair of limit rods 6 that is close to each other and the translation rod 62 on the same side. The bottom of the bottom plate 21 of the inner box 2 is fixedly connected to the extrusion plate 64. The front and rear sides of the left end of the extrusion plate 64 have an inclined surface 2 65 for extruding the translation rod 62.

[0032] The first outer box 1 is placed on the ground, and the inner box 2 in the second outer box 1 is as follows Figure 3 In the pulled-out state shown, the second outer box 1 is placed on top of the first outer box 1, and the limiting block 3 on the top of the first outer box 1 passes through the limiting hole 30 at the bottom of the second outer box 1. The limiting block 3 has a slope 32 to facilitate alignment of the limiting block 3 with the limiting hole 30. At this time, the items can be placed inside the second inner box 2 for storage.

[0033] Then, the second inner box 2 is pushed into the second outer box 1 by pushing the pull ring 46, driving the upper extrusion plate 64 to move to the left. The upper extrusion plate 64 squeezes the two translation rods 62 in the second outer box 1 through the two inclined surfaces 65. The two translation rods 62 slide away from each other in the front and rear directions. The return spring is compressed, and the limit rod 6 is driven to slide in the left and right directions under the transmission action of the rotating block 63. The four limit rods 6 slide in the direction close to the four limit blocks 3 respectively. The limit rods 6 are inserted into the card slots 31. The state of the limit rods 6 after sliding is as shown in FIG. Figure 10 As shown, the stacking of other outer boxes 1 is continued in the same way. In this way, through the cooperation of the limit rod 6 and the limit block 3, the position of the stacked outer boxes 1 can be relatively fixed, avoiding horizontal displacement between the upper and lower outer boxes 1, and realizing automatic locking of the outer boxes 1, reducing the risk of the outer boxes 1 tipping over during stacking and improving the stacking stability.

[0034] When the inner box 2 is pushed into the outer box 1, the insertion rod 4, the square hole 401 and the insertion hole 402 are aligned in the front-to-back direction. By pushing the pull ring 46, the fixed block 44 and the rotating disk 41 are driven to rotate together. The rotating rotating disk 41 pushes the two protrusions 43 away from each other through the arc groove 42. The protrusion 43 is located at the distal end of the arc groove 42, driving the two insertion rods 4 to slide away from each other in the front-to-back direction. The insertion rod 4 passes through the square hole 401, and the ends of the two insertion rods 4 are respectively extended into the two insertion holes 402, so that the positions of the inner box 2 and the outer box 1 are relatively fixed through the cooperation of the insertion rod 4 and the insertion hole 402, and the locking method of the inner box 2 is stable and convenient.

[0035] When it is necessary to take or place items inside the inner box 2, the pull ring 46 drives the rotating disk 41 to rotate in the opposite direction. The rotating disk 41 that rotates in the opposite direction pushes the two protrusions 43 to approach each other through the arc groove 42. The protrusion 43 is located at the proximal end of the arc groove 42, driving the two insertion rods 4 to slide in the front-to-back direction toward each other. The insertion rods 4 leave the insertion holes 402, and the inner box 2 can be pulled out to take or place items. The squeezing plate 64 moves to the right with the inner box 2; in the process of taking or placing items, the squeezing plate 64 keeps squeezing the translation rod When the outer boxes 1 stacked together need to be separated, the inner box 2 is pulled out to the right until the right side of the left side plate 23 contacts the left side of the limit bar 10, and the squeezing plate 64 is separated from the translation rod 62. The squeezing plate 64 no longer squeezes the translation rod 62, and the translation rod 62 slides and resets under the action of the reset spring, and the limit rod 6 is driven to slide and reset by the rotating block 63. The limit rod 6 leaves the slot 31, and the stacked outer boxes 1 can be separated, which is convenient to operate.

[0036] Implementation method 2: Based on implementation method 1, Figure 1 and Figure 11 As shown, the combined storage box that is easy to stack also includes a storage frame 71, a partition plate 73 and a baffle 74. Three storage frames 71 are placed inside the inner box 2. The top of the storage frame 71 is provided with a through hole 72. Two partition plates 73 are fixedly connected to the inside of the storage frame 71, and the right side of the partition plate 73 is fixedly connected to the baffle 74. When the inner box 2 is pulled out, the storage frame 71 is pulled out, and the items are classified and placed on the partition plates 73. The baffle 74 plays a role in blocking the items to prevent the items from sliding off the partition plates 73. Then the storage frame 71 is pushed into the inner box 2. In this way, the items can be classified and stored, which improves practicality.

[0037] like Figure 1 、 Figure 2 and Figure 5As shown, the combined storage box that is easy to stack also includes a rotating plate 8. Embedded holes 80 are opened on the front and back sides of the outer box 1. The outer box 1 is rotatably connected to the rotating plate 8 at the embedded holes 80; the rotating plate 8 is located in the embedded holes 80, and the side of the rotating plate 8 is flush with the side of the outer box 1. By pulling the rotating plate 8 upward to rotate, holding the rotating plate 8 to assist in moving the position of the outer box 1, it is convenient to transfer the outer box 1.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
