Description

Technical Field

[0001] This utility model relates to the field of packaging gift box technology, and in particular to a child-proof drawer box. Background Technology

[0002] Early woodworking mortise and tenon joints and sliding rail improvements were made by using limiting bosses, damping rails and modular slots to achieve smooth opening and closing and spatial subdivision. Modern injection molding and metal stamping processes introduced self-lubricating sliders and hidden buffers to improve noise reduction, dust prevention and load-bearing performance.

[0003] Existing drawer boxes lack child-proof features. Due to the low floor or tabletop, children can easily pull them open with one hand while crawling, posing a risk of swallowing small parts or ingesting medication. Furthermore, if parents do not push the drawer back in time, toddlers may knock over the open drawer when they get up to walk in the early morning, causing falls or injuries. Additionally, the single-layer sidewalls reduce the resistance to pressure, squeezing, and torsion, making the drawer prone to bulging or partial collapse. Uneven guide rails during pulling can also cause uneven friction distribution, resulting in jamming, wobbling, shaking, and abnormal noises. Utility Model Content

[0004] The main purpose of this utility model is to provide a child-proof drawer box, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A child-proof drawer box includes an outer box and an inner box, the outer box and the inner box being slidably connected, and a foam inner support being provided on the inner surface of the inner box; a locking fastener is fixedly connected to one side of the outer surface of the foam inner support.

[0007] To ensure stable functionality, this utility model provides a child-proof drawer box, the outer box comprising a first main surface, a fold line on one side of the outer surface of the first main surface, a side surface fixedly connected to one side of the outer surface of the first main surface, a second main surface fixedly connected to one side of the side surface, and a valley fold fixedly connected to one side of the outer surface of the first main surface and the second main surface.

[0008] To achieve double-layer reinforcement, as a child-proof drawer box according to this utility model, the inner box includes a bottom plate, a left structural strip is fixedly connected to one side of the outer surface of the bottom plate, a right structural strip is fixedly connected to one side of the outer surface of the bottom plate, and an edge band is fixedly connected to one side of the outer surface of the bottom plate.

[0009] To achieve a limiting effect, the outer surface of the child-proof drawer box of this utility model has a perforation on one side.

[0010] To ensure its elasticity, the foam inner tray of this invention, designed to prevent children from opening the drawer, is made of polyurethane foam.

[0011] In order to achieve the purpose of pressing, as a child-proof drawer box of this utility model, the locking element is made of injection-molded plastic, and the outer surface of the locking element is provided with circular protrusions.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, through the setting of an outer box, an inner box, a foam inner tray, and a locking device, during use, the hole in the side wall of the outer box is used as a fixed fulcrum, and the inner foam inner tray continuously pushes the injection-molded plastic locking device with protrusions on the outside, so that the protrusions extend into the hole to form a mechanical blockage. Only when an adult presses the protrusions and pushes the locking device inward to disengage from the hole can the inner box be pulled out. After releasing the hand, the foam inner tray quickly and elastically resets and pushes the protrusions into the hole again to maintain the lock. With an extremely inexpensive and metal-free structure, it effectively prevents children from opening the drawer with one hand or unintentionally. At the same time, it takes into account the advantages of environmental protection, recycling, and automated production, and achieves the purpose of solving the problem of preventing children from opening the drawer, protecting the performance, and ensuring safe use.

[0014] 2. In this utility model, through the arrangement of a first main surface, a side surface, a second main surface, a fold, and a bottom plate, during use, the outer box is folded along the fold line between the first main surface and the side surface, making the side surface upright. Then, the fold line between the side surface and the second main surface is continued to be folded, making the second main surface upright, so that the first main surface, side surface, and second main surface form a continuous right-angle frame. Subsequently, the narrow side surface on the other side and the overlapping tongue are folded along the corresponding fold line to close the cylinder. The overlapping tongue is then glued and pressed to the inner side of the first main surface to form a cylinder. Finally, the flange is folded along the transverse fold lines of the upper and lower openings to form the cylinder. To correct the squareness of the four sides, using the base plate as a reference, first fold the base plate upwards along the crease between it and the left structural strip, then fold it back along the inner fold line to form a double-layer reinforced edge on the left. In the same way, fold the right structural strip upwards along the crease between it and the base plate, and then fold it back along the inner fold line to form a double-layer reinforced edge on the right. Then, fold the edge along the crease adjacent to the base plate inwards to reinforce the overlap and press it together. Finally, apply glue to the inside of the four corner tabs and press them together to correct the squareness. This results in a tray-type box with upright side walls and reinforced edges, achieving a consistent molding. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figure 1-5 As shown, a child-proof drawer box includes an outer box 1 and an inner box 2. The outer box 1 and the inner box 2 are slidably connected, and a foam inner support 3 is provided on the inner surface of the inner box 2.

[0024] In this embodiment, a locking fastener 4 is fixedly connected to one side of the outer surface of the foam inner support 3.

[0025] In practical use, the user uses the hole cut into the side wall of the outer box 1 as a fixed fulcrum. The built-in foam inner support 3 continuously pushes outward the plastic locking piece 4 with protrusions, so that it extends into the hole to form a mechanical blockage. The drawer can only be pulled out when an adult presses the protrusions at the same time and pushes the locking piece 4 inward to disengage from the hole. After releasing the hand, the foam inner support 3 automatically resets and continues to lock, thus achieving the purpose of preventing children from opening the drawer with one hand or unintentionally at a low cost.

[0026] In this embodiment, the outer box 1 includes a first main surface 5, a fold line is provided on one side of the outer surface of the first main surface 5, a side surface 6 is fixedly connected to one side of the outer surface of the first main surface 5, a second main surface 7 is fixedly connected to one side of the side surface 6, and a valley fold 8 is fixedly connected to one side of the outer surface of the first main surface 5 and the second main surface 7.

[0027] In practical use, the outer box 1 takes the first main surface 5 as the reference, and makes a valley fold 8 along the fold line between it and the side surface 6 to make the side surface 6 stand up. Then, it continues to make a valley fold 8 along the fold line between the side surface 6 and the second main surface 7 to make the second main surface 7 stand up, so that the first main surface 5, the side surface, and the second main surface 7 form a continuous right angle frame. Then, the narrow side surface 6 on the other side and the overlapping tongue are made to make a valley fold 8 along the corresponding fold line to close the cylinder. The overlapping tongue is then glued and pressed to the inside of the first main surface 5 to form a cylinder. Finally, the flange is folded along the horizontal fold line of the upper and lower openings to form the shape and correct the squareness of the four sides.

[0028] In this embodiment, the inner box 2 includes a base plate 9, a left structural strip 10 is fixedly connected to one side of the outer surface of the base plate 9, a right structural strip 11 is fixedly connected to one side of the outer surface of the base plate 9, and an edge banding 12 is fixedly connected to one side of the outer surface of the base plate 9.

[0029] In practical use, with the base plate 9 as the reference, first stand it up along the crease between the base plate 9 and the left structural strip 10, then fold it back along the inner fold line to form a double-layer reinforced edge on the left. In the same way, fold the right structural strip 11 up along the crease between it and the base plate 9, and then fold it back along the inner fold line to form a double-layer reinforced edge on the right. Then, fold the edging 12 inward along the crease adjacent to the base plate 9 to reinforce the overlap and press it together. Finally, apply glue to the inside of the four corner glue tongues and press them together to correct the squareness, thus obtaining a tray-type structure with upright side walls and reinforced edges.

[0030] In this embodiment, a perforation is provided on one side of the outer surface of the outer box 1.

[0031] In practical use, adults can simply press the protrusion inward with their fingers to retract the latch 4 into the hole and instantly unlock the drawer, achieving a safety mechanism that allows for opening with a single hand press, while making it difficult for children to press from both sides at the same time.

[0032] In this embodiment, the material of the foam inner support 3 is polyurethane foam.

[0033] In practical use, when an external force compresses the inner foam support 3 in the opposite direction, the locking element 4 retracts and unlocks. After the external force is removed, the polyurethane foam immediately releases its potential energy, restores its original shape, and pushes out the locking element 4 again to maintain the lock, completing one floppy drive, metal-free automatic reset cycle.

[0034] In this embodiment, the material of the locking element 4 is injection-molded plastic, and the outer surface of the locking element 4 is provided with circular protrusions.

[0035] In actual use, when an adult presses the protrusion with their fingertip, the entire plastic part moves into the box. Once the protrusion is completely dislodged from the hole, the lock is released. After releasing the hand, the sponge rebounds, and the plastic lock buckle 4 pushes the protrusion back into the hole. The material's toughness and injection molding precision ensure reliable locking and smooth sliding in each cycle.

[0036] Working principle: During use, the user uses the hole in the side wall of the outer box 1 as a fixed fulcrum. The built-in foam inner support 3 continuously pushes outward the plastic locking piece 4 with protrusions, causing it to extend into the hole and form a mechanical jam. The drawer can only be pulled out when an adult presses the protrusions and pushes the locking piece 4 out of the hole. After releasing the hand, the foam inner support 3 automatically resets and continues to lock, thus achieving the purpose of preventing children from opening the drawer with one hand or unintentionally at a low cost. The outer box 1 is based on the first main surface 5. The fold line between it and the side surface 6 is folded into a valley 8 to make the side surface 6 stand up. Then, the fold line between the side surface 6 and the second main surface 7 is folded into a valley 8 to make the second main surface 7 stand up, so that the first main surface 5-side surface-second main surface 7 form a continuous right angle frame. Then, the narrow side surface 6 on the other side is connected to the overlapping tongue. Fold along the corresponding fold line 8 to close the cylinder, and then glue and press the overlapping tongue with the inner side of the first main surface 5 to form a cylinder. Finally, fold the flange along the horizontal fold line of the upper and lower openings to form a mountain fold, and correct the squareness of the four sides. Taking the base plate 9 as the reference, first fold the base plate 9 and the left structural strip 10 upwards, and then fold it back along its inner fold line to form a double-layer reinforced edge on the left. In the same way, fold the right structural strip 11 along the fold line with the base plate 9 to form a valley fold, and then fold it back along its inner fold line to form a double-layer reinforced edge on the right. Then, fold the edge band 12 inward along the fold line adjacent to the base plate 9 to reinforce the overlapping and pressing. Finally, apply glue to the inner side of the four corner glue tongues and press to correct the squareness. This gives a tray-type box with upright side walls and reinforced edges, achieving the purpose of consistent molding.
