Description

Technical Field

[0001] The utility model relates to a box, in particular to an integrally formed box with a child lock. Background Art

[0002] A box is a three-dimensional multifaceted shape formed by the movement, stacking, folding and encirclement of multiple faces. The faces in the three-dimensional structure play the role of dividing the space in space. Cutting, rotating and folding the faces in different parts will give different emotional expressions. The biggest role of a box is to hold items. Boxes are frequently used in daily furniture life. Boxes can be used to hold most household items, such as keys, medicines, books and buttons, etc. When there are children who are not familiar with the world in the family, it is particularly important to keep fragmentary items and medicines that are easy to cause harm to children. Most of the ordinary boxes on the market are convenient for users to use, and the top cover generally does not have a locking function. In this case, if fragmentary items and medicines that are easy to cause harm to children are kept in a box without a child lock function, it will bring great safety hazards to families with children.

[0003] For example: the currently disclosed publication number is CN210681704U, and the patent name is a Chinese authorized patent for a box, which includes a box body, which is formed with a storage space, and the box body includes a first end plate, a second end plate and two side end plates, each of which is connected to the first and second end plates respectively; a flip cover, including a support part and a cover part mounted on the two side end plates; one end of the support part is hinged to the side of the cover part facing away from the storage space, and the other end is hinged to the second end plate; the side end plate is provided with a limiting groove located in the storage space, and the cover part is provided with a sliding member extending into the storage space and slidingly arranged in the limiting groove. After the box provided by the utility model is opened, the flip cover can effectively realize the limit and maintain a fixed maximum opening position; and the structure of the entire flip cover has good stability, which can effectively and stably maintain the maximum opening position.

[0004] Or the currently disclosed Chinese authorized patent with publication number CN212099715U and patent name of paper box, which includes a box body and a box cover, a rectangular opening is arranged at the upper end of the box body, a storage cavity is arranged inside the box body, the surface of the storage cavity is partially sunken to form a plurality of placement grooves, a card slot is arranged at the bottom of the box body, a storage box of corresponding shape is placed in the card slot, openings are arranged on both the front and rear sides of the storage box, and the rear edge of the box cover is connected to the rear edge of the box body. The storage box can be used to place edible small tools and as a storage space in the future. The folding layer of the inner wall of the placement groove can adjust the placement groove depth according to the placed items. The utility model has a simple structure, high practicality and beautiful appearance.

[0005] The above-mentioned example patent can effectively limit the flip cover after the box is opened, maintain a fixed maximum opening position or adjust the depth of the placement groove according to the items placed. However, as mentioned above, it does not have a protective function against children accidentally opening the box. In this way, when medicines, toxic substances, paints or skin care products that are easy to cause harm to children are stored in the box, if the child opens the box and accidentally touches or even eats the items in the box, it will cause irreparable harm to the user's family.

[0006] In addition, during the manufacturing process, some of the connecting side panels of the above-mentioned patent are assembled and formed by gluing. The glue is easy to debond and crack after long-term use, which leads to damage to the box body. In addition, it is difficult to disassemble and fold for transportation after gluing, and the transportation after assembly occupies a large area, which affects the long-term daily use needs.

[0007] In view of the above reasons, it is necessary to design an integrally formed box with a built-in child lock to meet the daily use needs of users. Utility Model Content

When the side guard plates 7 are folded onto the side panels 6 through the folds, the limiting grooves 18 are aligned and overlapped with the locking recesses 19, and when the locking plate 11 is folded and overlapped on the side guard plates 7 through the folds, the two spring pieces 17 are stuck in the limiting grooves 18 and the locking recesses 19 on the same side, so as to self-lock the top plate 9 just above the bottom plate 1, and the two spring pieces 17 are connected to the folds on the reinforcing portion 12 on the same side, and the two spring pieces 17 are separated from the locking plate 11 on the same side, and the two spring pieces 17 are tilted away from the locking plate 11 on the same side.

[0035] like Figure 1 , Figure 3 , Figure 4 and Figure 7As shown, it also includes a side lining 8, a top lining 13 and a front lining 14. The sides of the two side guard plates 7 that are away from each other are integrally connected to the side lining 8 through a fold, the sides of the two reinforcement parts 12 that are away from each other are integrally connected to the top lining 13 through a fold, and the lower side of the front side panel 3 is integrally connected to the front lining 14 through a fold. When the box is folded, the side guard plates 7 on the same side are folded and overlapped on the side panels 6 on the same side, and the two side linings 8 are folded and abutted against the bottom plate 1. Similarly, when the box is folded, the reinforcement parts 12 on the same side are folded and overlapped on the snap-fitting plates 11 on the same side, and the two top linings 13 are folded and abutted against the top plate 9. Initially, the fold between the side lining 8 and the side guard plates 7 on the same side is shallow. After the box is folded and the two side linings 8 are folded and abutted against the bottom plate 1 The lining 8 is affected by the restoring force of its own material, and the two side linings 8 will press against the bottom plate 1, so as to increase the friction between the two side linings 8 and the bottom plate 1, prevent the two side linings 8 from being separated from the contact between the bottom plate 1, and prevent the side guard plate 7 on the same side from being separated from the folded overlapping state with the side panel 6 on the same side. Initially, the crease between the top lining 13 on the same side and the reinforcement part 12 on the same side is shallow. After the box is folded and the two top linings 13 are folded and abutted against the top plate 9, the two top linings 13 are affected by the restoring force of their own material, and the two top linings 13 will press against the top plate 9, so as to increase the friction between the two top linings 13 and the top plate 9, prevent the two top linings 13 from being separated from the contact between the top plate 9, and prevent the reinforcement part 12 on the same side from being separated from the folded overlapping state with the snap plate 11 on the same side.

[0036] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a card plate 15, and the left and right sides of the front lining 14 are extended and connected with the card plates 15, and the lower sides of the two side guard plates 7 are provided with positioning holes 16 that cooperate with the card plates 15. When the box is folded, the front lining 14 and the front side panel 3 are folded and overlapped, and the card plate 15 on the same side is inserted into the positioning hole 16 on the side guard plate 7 on the same side, and under the premise that the two side liners 8 do not lose contact with the bottom plate 1, the side panel 6 on the same side and the side guard plate 7 on the same side always maintain a folded and overlapped state, so that the card plate 15 on the same side will remain stuck by the positioning hole 16 on the side guard plate 7 on the same side, thereby maintaining the folded and overlapped state of the front lining 14 and the front side panel 3.

[0037] like Figure 1 , Figure 5 and Figure 6As shown, it also includes a front plug-in board 4 and a rear plug-in board 5. The left and right sides of the front side board 3 are integrally connected to the front plug-in board 4 through folds, and the sides of the front plug-in board 4 on the same side that are away from each other are extended and connected with a positioning convex portion 401, and the left and right sides of the rear side board 2 are integrally connected to the rear plug-in board 5 through folds, and the sides of the rear plug-in board 5 on the same side that are away from each other are provided with a recessed slot 501. When folded, the positioning convex portion 401 on the front plug-in board 4 on the same side will be inserted into the recessed slot 501 on the rear plug-in board 5 on the same side, as shown in FIG. Figure 5 and Figure 6 As shown, when the box is folded, the rear plug-in board 5 and the front plug-in board 4 on the same side are inserted into the gap between the side guard plate 7 and the side panel 6 on the same side.

[0038] During assembly, firstly, fold and erect the two front plug-in boards 4 on the front side boards 3 along the folds, and fold and erect the two rear plug-in boards 5 on the rear side boards 2 along the folds, then fold and erect the rear side boards 2 on the bottom board 1 along the folds, and fold and erect the front side boards 3 on the bottom board 1 along the folds, and move the front plug-in boards 4 and the rear plug-in boards 5 accordingly, and then insert the clamping protrusions 401 on the front plug-in boards 4 on the same side into the recessed clamping slots 501 on the rear plug-in boards 5 on the same side, so that the front and rear sides of the box are closed and connected, and then fold and erect the side panels 6 on the bottom board 1 along the folds, and then fold the side guard panels 7 along the folds between the sides of the side panels 6 that are close to each other, so that the side guard panels 7 and the side panels 6 on the same side are folded and reassembled. When the side guard plate 7 is rotated to be folded and overlapped with the side panel 6 on the same side, the bottom plate 1 will squeeze the two side linings 8, so that the two side linings 8 are folded away from the bottom plate 1, and after the side guard plate 7 is folded and overlapped with the side panel 6 on the same side, the two side linings 8 are both abutted against the inner side of the bottom plate 1, and the side linings 8 are used to abut the side guard plate 7 to prevent the side panel 6 and the side guard plate 7 from flipping up at will, and at this time, the two limiting grooves 18 are aligned and overlapped with the locking notches 19 on the same side, and at the same time, the side guard plate 7 and the side panel 6 wrap the front plug-in plate 4 on the same side and the rear plug-in plate 5 on the same side, so as to improve the connection stability of the front plug-in plate 4 and the rear plug-in plate 5, and then the front lining 14 is folded into the inner side of the front side panel 3 along the crease, so that the front lining 14 and the front side panel 3 are folded together, so that the card plate 15 will be inserted into the positioning hole 16 on the side guard plate 7 on the same side, so as to improve the connectivity between the front side panel 3 and the side guard plate 7, prevent the front side panel 3 from being arbitrarily separated from the contact with the side guard plate 7, and clamp the front lining 14 to prevent the front lining 14 from being separated from the folded state with the front side panel 3. At this point, the front, back, left and right sides of the box are all blocked together, and under the joint action of the front plug-in plate 4, the rear plug-in plate 5, the side lining 8 and the card plate 15, the front, back, left and right side connections of the box are more stable, and then the snap plate 11 can be folded and erected on the top plate 9 along the crease, and then the reinforcement part 12 is folded inwardly on the snap plate 11 on the same side, so that the reinforcing part 12 is folded and overlapped with the snap plate 11 on the same side. When the reinforcing part 12 is rotated to be folded and overlapped with the snap plate 11 on the same side, the top plate 9 will squeeze the two top liners 13, so that the two top liners 13 are folded away from the top plate 9, and after the reinforcing part 12 is folded and overlapped with the snap plate 11 on the same side, the two top liners 13 are both abutted against the inner side of the top plate 9, and the reinforcing part 12 is abutted by the top liners 13 to prevent the snap plate 11 and the reinforcing part 12 from flipping up at will, and then the sealing strip 10 is folded and erected along the fold on the top plate 9, and the assembly of the box is completed at this time.

[0039] If the box needs to be closed and self-locked, the top plate 9 can be folded along the fold toward the bottom plate 1 to align the snap plate 11 with the side guard plate 7, and then the snap plate 11 is inserted into the bottom plate 1 between the sides of the two side guard plates 7 that are close to each other. At the same time, the spring piece 17 will be pressed against the side guard plate 7 on the same side as the snap plate 11 moves, and the spring piece 17 will be squeezed between the snap plate 11 and the adjacent side guard plate 7. The spring piece 17 will be squeezed by the side guard plate 7 to rotate toward the snap plate 11, and when the spring piece 17 is aligned with the positioning recess 19 and the limiting groove 18, the spring piece 17 will rebound in the limiting groove 18 under the reset action of the material itself, and the spring piece 17 will be stuck in the positioning recess 19 and the limiting groove 18, thus avoiding the snap plate 11, the reinforcement part 12 and the top plate 9 can be flipped up at will, so that the top of the box is opened, and when the top plate 9 is rotated and closed, it will also drive the sealing strip 10 to rotate. When the top plate 9 contacts the front side plate 3 and the front lining 14, the sealing strip 10 will be rotated and inserted into the inner side of the front lining 14, so that the sealing strip 10 is in contact with the inner side of the front lining 14, so that the box can be closed. Under the clamping action of the spring piece 17 and the clamping notch 19 and the limiting groove 18, the box realizes the self-locking function, preventing children from opening it at will, reducing the safety hazard of children accidentally touching or even eating the items inside the box, and improving the safety of the box for storing items. The side guard plate 7 is overlapped and folded with the side panel 6, and the front lining 14 is overlapped and folded with the front side plate 3, so as to enhance the stability of the box structure and the pressure resistance after accommodating items.

[0040] The spring piece 17 is engaged with the locking recess 19 and the limiting groove 18 to form a child lock. After the top plate 9 is closed, the top plate 9 of the box is automatically locked to prevent children from accidentally opening the box. When the user needs to open the box, he puts his fingers into the unlocking holes 20 on the left and right sides, and the fingers can touch the spring piece 17. Then, the spring piece 17 is pressed hard to fold the spring piece 17 and rotate it in the direction of the locking plate 11 on the same side. In this way, the spring piece 17 will be disengaged from the locking recess 19 and the limiting groove 18, and then the top plate 9 can be pressed to flip the cover upward to open it. This operation is simple and quick, and the unlocking method is secret and not easy to be discovered. While preventing children from opening the box at will, the unlocking is also simple and easy to operate, thereby improving the applicability of the box.

[0041] The above-mentioned parts of the box are all made of hard cardboard to improve the overall stability of the box, and the fitting position between the side lining 8 and the bottom plate 1 is roughened to improve the static friction between the side lining 8 and the bottom plate 1, so as to avoid the side lining 8 and the bottom plate 1 from loosening and detaching when they are fitted together, thereby avoiding affecting the folding and fitting between the side panel 6 and the side guard plate 7. Similarly, the fitting position between the top lining 13 and the top plate 9 is roughened to improve the top lining 13 and the top plate 9. The static friction between the lining 13 and the top plate 9 prevents the top lining 13 and the top plate 9 from loosening and detaching when they are attached together, thereby preventing the folding and attaching between the snap plate 11 and the reinforcement part 12 from being affected. In this way, under the action of the high friction between the side lining 8 and the bottom plate 1, the side panel 6 and the side guard plate 7 can have a strong folding overlap stability, thereby reducing the risk of the snap-in convex portion 401 on the front plug-in plate 4 and the concave snap-in 501 on the rear plug-in plate 5 detaching. Under the action of the high friction force between the lining 13 and the top plate 9, it can ensure that the snap plate 11 and the reinforcement part 12 have strong folding overlap stability. On this premise, the snap plate 15 on the front lining 14 can be maintained stably in the positioning hole 16 on the side guard plate 7. Based on the mutual clamping cooperation of the above-mentioned components, the stable connection of the panels of the box body can be achieved, and the connection method adopts a mutual clamping force method. No additional glue or tape or other tools are required to fix the connection, which reduces the use of resources and improves the use of environmentally friendly products. At the same time, when disassembly is required, it is only necessary to remove the side lining 8 from the bottom plate 1 to unlock the folded state of the side panel 6 and the side guard plate 7, and remove the top lining 13 from the top plate 9 to unlock the folded state of the snap plate 11 and the reinforcement part 12. After that, the clamping convex part 401 on the front plug-in plate 4 can be unfastened and disengaged from the recessed snap-in hole 501 on the rear plug-in plate 5.
