Description

Technical Field

[0001] The present invention relates to the field of food storage boxes, in particular to a multifunctional food box. Background Art

[0002] Food packaging is not only to meet the hygienic requirements of the food itself, but also to increase market competitiveness. Currently, food packaging is diverse. For example, candy packaging has evolved from simple folding or bundling of candy wrappers to the current diversified packaging such as paper boxes and bags.

[0003] Currently, most food packaging is disposable boxes and bags, which have a low reuse rate and are thrown away after purchase, which is not conducive to resource reuse. In addition, there are some reusable packaging boxes on the market. Although they avoid the above problems, the food storage containers need to be cleaned, which is troublesome to clean and extremely inconvenient to use. Summary of the Invention

[0004] In view of the defects in the prior art, the present invention provides a multifunctional food box to improve the reuse rate of the packaging box, reduce the difficulty of cleaning, and make food more hygienic.

[0005] In response to the above technical problems, the present invention provides a multifunctional food box, comprising an upper box body, a lower box body, and a rotating shaft. The lower box body is overlapped and connected to the bottom of the upper box body and drives the upper and lower boxes to open via the rotating shaft. The upper box body comprises a first bottom plate, a first receiving box, a lifting bracket, a mounting cylinder, a rack, a first bevel gear, and a second bevel gear.

[0006] The first bevel gear is horizontally rotatably mounted on the middle portion of the first base plate and the first bevel gear is sleeved on the lower end of the rotating shaft, so that the first bevel gear and the rotating shaft rotate synchronously on the first base plate; the mounting cylinder is fixedly connected to the upper surface of the first base plate, the rack is slidably connected to the inner surface of the mounting cylinder along the vertical direction, and the second bevel gear is rotatably connected to the inner surface of the mounting cylinder, the second bevel gear is provided with a coaxial gear plate, the second bevel gear is meshed with the first bevel gear, and the gear plate is meshed with the rack;

[0007] The lifting bracket and the first receiving box are both sleeved on the outside of the mounting tube, and the first receiving box is placed on the lifting bracket, and the upper end of the rack is fixedly connected to the lifting bracket;

[0008] The device further comprises a box cover for covering the first storage box, wherein the box cover is hinged to the first bottom plate and drives the first bevel gear to rotate via the rotating shaft, thereby causing the rack and the lifting bracket to rise synchronously in the vertical direction and enable the first storage box to open the box cover.

[0009] The beneficial effects of the present invention are embodied in:

[0010] The upper and lower boxes can be easily opened by the rotating shaft, making food storage more convenient. At the same time, both the upper and lower boxes are reusable, which is conducive to the rational use of resources. In addition, the first storage box is placed on a lifting bracket. After the first storage box is opened, it can be completely removed for easy cleaning, greatly reducing the difficulty of cleaning and making food storage more hygienic.

[0011] Preferably, there are three second bevel gears and three racks, each second bevel gear is engaged with one rack, and the three second bevel gears are distributed along the circumference of the first bevel gear.

[0012] The three racks support the lifting bracket, so that the lifting bracket is more stable during the lifting process, and correspondingly makes the opening and closing of the first receiving box smoother.

[0013] Preferably, the side wall of the mounting cylinder is provided with a first sliding groove corresponding to each rack one by one, and each second bevel gear is rotatably connected to the mounting cylinder through a fixing block.

[0014] Each rack moves up and down in the corresponding first sliding groove, and the first sliding groove plays a role of limiting, thereby preventing the rack from being misaligned and destroying the transmission relationship.

[0015] Preferably, the first accommodating box includes a plurality of single accommodating cylinders and a hollow cylinder with openings at both ends; the plurality of single accommodating cylinders are evenly distributed around the hollow cylinder and are fixedly connected to the outer wall of the hollow cylinder, the hollow cylinder is sleeved on the outside of the mounting cylinder and the hollow cylinder is placed on the lifting bracket.

[0016] There are five single-body accommodating cylinders, which can accommodate different foods and facilitate the classified storage of foods.

[0017] Preferably, the box cover is provided in plurality and each box cover corresponds to one of the monomer accommodating cylinders one by one, and the lower edge of each box cover is hinged to the upper surface of the first bottom plate.

[0018] Preferably, each of the box covers is provided with a pressure plate on the lower edge and a groove corresponding to each pressure plate is provided on the upper surface of the first bottom plate. The first accommodating box is lowered and all the pressure plates are pressed into the corresponding grooves, so that each box cover is respectively covered on the corresponding monomer accommodating tube.

[0019] During opening, the top of each cell housing pushes open its corresponding lid, and all the pressure plates simultaneously lift out of their corresponding grooves. Conversely, during closing, the bottom wall of each cell housing presses against its corresponding pressure plate and into its corresponding groove, automatically closing each lid onto its corresponding cell housing. All the lids are linked, opening and closing simultaneously for greater convenience.

[0020] Preferably, an extension tube is sleeved on the outside of the rotating shaft, and the inner surface of the extension tube is provided with a slide bar in the vertical direction, and the outer surface of the rotating shaft is provided with a second slide groove corresponding to the slide bar, and the upper end of the second slide groove extends in the horizontal direction to form a card slot, and the extension tube is provided with a protrusion corresponding to the card slot; the slide bar of the extension tube slides upward along the second slide groove, and then the extension tube is rotated and the protrusion is stuck in the card slot, so that the extension tube drives the rotating shaft to rotate synchronously.

[0021] To open, the extension tube is first pulled upward vertically, then rotated counterclockwise a certain angle until the protrusion snaps into the slot. During this process, the shaft does not move upward or rotate with the extension tube. Continued counterclockwise rotation causes the shaft to rotate counterclockwise in sync with the extension tube, opening the upper and lower housings. Because the protrusion is locked in the slot, the extension tube will not fall after release. Conversely, to close, the extension tube is rotated clockwise, causing the protrusion to exit the groove. However, the slider remains locked in the second slot. Continued clockwise rotation of the extension tube causes the shaft to rotate clockwise in sync, closing the upper and lower housings. Finally, push the extension tube downward to reset.

[0022] Preferably, a knob is provided at the upper end of the extension tube.

[0023] Preferably, the lower box body includes a second bottom plate, a second storage box, a rotating bracket and a rotating tray; the rotating bracket includes a rotating drum, the upper end of the rotating drum passes through the first bottom plate and is connected to the first bevel gear, and the lower end of the rotating drum is rotatably connected to the second bottom plate and the lower end of the rotating drum is provided with a branch rod; the rotating tray is rotatably connected to the upper surface of the second bottom plate by a pin shaft, and the rotating tray is hinged to the rotating bracket through a connecting rod; the second storage box is placed on the rotating tray, and the rotating bracket is driven to rotate by the first bevel gear, so that the connecting rod pushes the rotating tray and the second storage box out from between the first bottom plate and the second bottom plate along the circumferential direction.

[0024] Preferably, a plurality of branch rods are fixedly connected along the circumference of the rotating drum, there are a plurality of rotating trays, and each branch rod is hinged to a rotating tray in a one-to-one correspondence through a connecting rod; a second receiving box is placed on each rotating tray.

[0025] There are five second storage boxes, which are also used to accommodate different foods and facilitate the classified storage of foods. When the five second storage boxes and the rotating tray are opened, they swing outward in the circumference of the rotating drum with the rotating drum as the center. Each rotating tray swings around the corresponding pin under the push of the corresponding connecting rod. When closed, the rotating drum simultaneously drives the five branch rods to pull all the second storage boxes and rotating trays to swing in the opposite direction, so that they are retracted between the first bottom plate and the second bottom plate. The first bottom plate acts as the lid of the second storage box. After retraction, the first bottom plate covers the upper opening of each second storage box, which is convenient for food storage.

DETAILED DESCRIPTION

[0039] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0040] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0041] like Figures 1 to 5 As shown, this embodiment provides a multifunctional food box, including an upper box body 1, a lower box body 2 and a rotating shaft 5. The upper box body 1 and the lower box body 2 are driven to open by the rotating shaft 5. The specific structure of the upper box body 1 is as follows:

[0042] like Figures 6 to 11As shown, the upper box body 1 includes a first base plate 6, a first accommodating box 7, a lifting bracket 8, a mounting tube 9, a rack 10, a first bevel gear 11, and a second bevel gear 12. The first bevel gear 11 is horizontally rotatably mounted in the middle of the first base plate 6. The first bevel gear 11 is sleeved on the lower end of the rotating shaft 5 and is fixedly connected to the lower end of the rotating shaft 5, so that the first bevel gear 11 and the rotating shaft 5 rotate synchronously on the first base plate 6. The mounting tube 9 is fixedly connected to the upper surface of the first base plate 6, the rack 10 is slidably connected to the inner surface of the mounting tube 9 in the vertical direction, and the second bevel gear 12 is rotatably connected to the inner surface of the mounting tube 9. The second bevel gear 12 is provided with a coaxial gear plate 16, and the second bevel gear 12 is meshed with the first bevel gear 11, and the gear plate 16 is meshed with the rack 10. The upper end of the rack 10 is fixedly connected to the lifting bracket 8. Three second bevel gears 12 and three racks 10 are provided. Each second bevel gear 12 meshes with a rack 10, and the three second bevel gears 12 are distributed along the circumference of the first bevel gear 11. Each second bevel gear 12 is rotatably connected to the inner wall of the mounting tube 9 via a fixed block 14. Each fixed block 14 is provided with a fixed shaft 15, and the second bevel gear 12 is rotatably mounted on the corresponding fixed shaft 15, thereby forming a rotational connection between the second bevel gear 12 and the fixed block 14. Each rack 10 moves up and down within its corresponding first chute 13. The first chute 13 acts as a limiter to prevent misalignment between the rack 10 and the second bevel gear 12, which could disrupt the transmission relationship.

[0043] In this device, both the lifting bracket 8 and the first storage box 7 are sleeved onto the exterior of the mounting tube 9, with the first storage box 7 placed on the lifting bracket 8. The lifting bracket 8 is annular, and the first storage box 7 includes multiple individual storage tubes 17 and a hollow tube 18 with both ends open. The multiple individual storage tubes 17 are evenly distributed around the hollow tube 18 and are fixedly connected to the outer wall of the hollow tube 18. The hollow tube 18 is sleeved onto the exterior of the mounting tube 9 and placed on the lifting bracket 8. In addition, a space 19 for the first storage box 7 is provided in the middle of the upper surface of the first base plate 6 to facilitate positioning of the first storage box 7.

[0044] The apparatus also includes a lid 3 for covering the first storage box 7. The lid 3 is hingedly connected to the first base plate 6 and rotates via the rotating shaft 5, driving the first bevel gear 11 to rotate. This in turn causes the rack 10 and the lifting bracket 8 to rise vertically, allowing the first storage box 7 to push the lid 3 open. Specifically, multiple lids 3 are provided, each corresponding to a single-cell storage tube 17. The lower edge of each lid 3 is hingedly connected to the upper surface of the first base plate 6. Furthermore, a pressure plate 20 is provided on the lower edge of each lid 3, and a groove 21 corresponding to each pressure plate 20 is provided on the upper surface of the first base plate 6. As the first storage box 7 descends and all pressure plates 20 are pressed into their corresponding grooves 21, each lid 3 is positioned over its corresponding cell storage tube 17. During the opening process, the upper edge of each cell storage tube 17 pushes open its corresponding lid 3, and all pressure plates 20 simultaneously lift from their corresponding grooves 21. Conversely, during the closing process, the bottom wall of each monomer accommodating tube 17 presses against the corresponding pressing plate 20 and into the corresponding groove 21, thereby causing each box cover 3 to automatically cover the corresponding monomer accommodating tube 17. All the box covers 3 are linked to form a structure that opens and closes simultaneously, which is more convenient to use.

[0045] The specific structure of the lower box body 2 in this embodiment is as follows:

[0046] like Figure 6 、 Figure 7 、 Figure 10 and Figure 11As shown, the lower box body 2 includes a second bottom plate 22, a second receiving box 23, a rotating bracket 24 and a rotating tray 25; the rotating bracket 24 includes a rotating drum 26, the upper end of the rotating drum 26 passes through the first bottom plate 6 and is connected to the first bevel gear 11, and the lower end of the rotating drum 26 is rotatably connected to the second bottom plate 22 and the lower end of the rotating drum 26 is provided with a branch rod 27; the rotating tray 25 is rotatably connected to the upper surface of the second bottom plate 22 through a pin shaft 29, and the rotating tray 25 is hinged to the rotating bracket 24 through a connecting rod 28; the second receiving box 23 is placed on the rotating tray 25, and the rotating bracket 24 is driven to rotate by the first bevel gear 11, so that the connecting rod 28 pushes the rotating tray 25 and the second receiving box 23 out from between the first bottom plate 6 and the second bottom plate 22 along the circumferential direction. Multiple branch rods 27 are fixedly connected along the circumference of the rotating drum 26. There are multiple rotating trays 25, each of which is hingedly connected to a corresponding rotating tray 25 via a connecting rod 28. Each rotating tray 25 houses a second storage box 23. Five second storage boxes 23 are provided, also designed to accommodate different food items and facilitate categorized storage. When opened, the five second storage boxes 23 and the rotating trays 25 simultaneously swing outward around the rotating drum 26. Each rotating tray 25 swings around a corresponding pin 29, driven by a corresponding connecting rod 28. The pins 29 are fixedly connected between the first base plate 6 and the second base plate 22, supporting the first base plate 6 on the second base plate 22. When closed, the rotating drum 26 simultaneously drives the five branch rods 27, pulling all the second storage boxes 23 and the rotating trays 25 in opposite directions, retracting them between the first base plate 6 and the second base plate 22. In this device, the second storage box 23 and each single storage tube 17 are open at the upper end. The second bottom plate 22 of the lower box body 2 overlaps with the first bottom plate 6 of the upper box body 1, and the second box body is located between the second bottom plate 22 and the first bottom plate 6, so that the first bottom plate 6 acts as the lid of the second storage box 23. After retracting, the first bottom plate 6 covers the upper end opening of each second storage box 23, which is convenient for food storage.

[0047] like Figure 11As shown, to facilitate manual rotation of the shaft 5, an extension tube 30 is sleeved around the shaft 5. The inner surface of the extension tube 30 is provided with a vertically extending slide 31. The outer surface of the shaft 5 is provided with a second slot 32 corresponding to the slide 31. The upper end of the second slot 32 extends horizontally to form a latching slot 33. The extension tube 30 is provided with a protrusion corresponding to the latching slot 33. By sliding the slide 31 of the extension tube 30 upward along the second slot 32, the extension tube 30 is rotated, causing the protrusion to engage with the latching slot 33, thereby causing the extension tube 30 to rotate synchronously with the shaft 5. During the opening process, the extension tube 30 is first pulled vertically upward, then rotated counterclockwise a certain angle until the protrusion engages with the latching slot 33. During this process, the shaft 5 does not move upward or rotate with the extension tube 30. Continued counterclockwise rotation then causes the shaft 5 to rotate counterclockwise with the extension tube 30, opening the upper and lower housings 1 and 2. Because the protrusion is locked in the slot 33, the extension tube 30 will not fall after releasing the handle. Conversely, during the closing process, the extension tube 30 is rotated clockwise. The protrusion first exits the groove 21, but the slide 31 remains locked in the second slide slot 32. Continuing to rotate the extension tube 30 clockwise will drive the rotating shaft 5 to rotate clockwise synchronously, closing the upper and lower boxes 1 and 2. Finally, push the extension tube 30 downward to reset it. A knob 4 is provided at the upper end of the extension tube 30.

[0048] The opening process of this device is as follows: manually hold the knob 4, first pull it vertically upwards, then rotate it counterclockwise to a certain angle, and then continue to rotate it counterclockwise until the five single-unit storage tubes 17 rise to the highest point and push open the box cover 3. At the same time, the five second storage boxes 23 are pushed out from between the first bottom plate 6 and the second bottom plate 22 along the circumferential direction.

[0049] Closing process: manually rotate the knob 4 clockwise, the five monomer accommodating cylinders 17 drop to the lowest point, and the five box covers 3 automatically cover the five monomer accommodating cylinders 17. At the same time, the five second accommodating boxes 23 are retracted circumferentially between the first bottom plate 6 and the second bottom plate 22.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
