Technical Field

[0001] This utility model relates to the opening and closing structure of a turnover box, and in particular to a built-in magnetic attraction structure for a traditional tobacco leaf box with Velcro fasteners. Background Technology

[0002] As a key container for cigarette processing and logistics transportation, tobacco turnover boxes are typically made of large-capacity stainless steel cabinets or early small containers. However, these technologies have the following problems: the metal material is prone to condensation and static electricity, which affects the quality of tobacco. When packing materials, tobacco is easily broken and the box is easily damaged by impact, which further increases maintenance costs.

[0003] In the prior art, utility model patent with application number "201520755579.2" discloses a turnover box. It points out that in the prior art, the material of the tobacco box is changed to PP hollow board for production. At the same time, the long side cover and the short side cover of the turnover box are fixed by Velcro. However, the Velcro needs to be pressed firmly against each other. If there is no pre-positioning, misalignment is likely to occur, and the connection effect will be poor. Utility Model Content

[0004] The purpose of this invention is to provide a built-in magnetic structure for the Velcro fastener of a tobacco leaf box, which serves as a pre-positioning mechanism before the Velcro fastener is connected.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a built-in magnetic suction structure for a tobacco leaf box with Velcro closure, comprising a box body, the box body including a long side cover plate and a short side cover plate, the short side cover plate being symmetrically rotatably connected to both sides of the short side of the box body, the long side cover plate being symmetrically rotatably connected to both sides of the long side of the box body, the long side cover plate correspondingly covering the top of the short side cover plate, the bottom of the long side cover plate being provided with a Velcro closure surface, the top of the short side cover plate being correspondingly provided with a Velcro closure surface, the bottom of the long side cover plate being provided with a fixing plate, the fixing plate being provided with a covering layer, a magnetic suction element being provided between the fixing plate and the covering layer, a first connecting element being provided between the covering layer and the fixing plate, the first connecting element fixing the covering layer and the fixing plate to the long side cover plate, the short side cover plate being provided with a ferromagnetic metal plate corresponding to the magnetic suction element, the ferromagnetic metal plate being provided with a second connecting element, the second connecting element fixing the ferromagnetic metal plate to the bottom of the long side cover plate.

[0006] Preferably, the sum of the thicknesses of the fixing plate, magnetic clasp, covering layer, and ferromagnetic metal plate is greater than the sum of the thicknesses of the hook and loop fastener's outer surface and its inner surface.

[0007] By adopting the above technical solution, the magnetic components are pre-positioned, avoiding the initial fixed connection between the hook and loop fastener side and the hook and loop fastener side.

[0008] Preferably, the covering layer extends beyond the fixing plate and connects to the bottom of the long side cover plate, the covering layer is rectangular, and the covering layer extends along the width direction of the fixing plate.

[0009] By adopting the above technical solution, the connection area of ​​the coating layer is increased, thereby improving the fixing effect on the magnetic components.

[0010] Preferably, the coating layer comprises a Teflon upper layer and an adhesive lower layer.

[0011] By adopting the above technical solution, the adhesive lower layer serves as a connector, while the Teflon upper layer provides abrasion resistance, thereby improving the service life of the enclosure.

[0012] Preferably, the width of the hook and loop fastener side is equal to the width of the hook and loop fastener side, the length of the hook and loop fastener side is less than half the length of the hook and loop fastener side, the hook and loop fastener side is located in the middle of the short side cover plate, and the hook and loop fastener side and the hook and loop fastener side are arranged in a rectangle.

[0013] By adopting the above technical solution, it is ensured that the hook and loop fastener side corresponds to the hook and loop fastener side, thereby improving the connection effect between the two.

[0014] Preferably, an adhesive area for bonding the covering layer is formed between the Velcro side and the fixing plate, and the covering layer covers the edge of the fixing plate.

[0015] By adopting the above technical solution, a certain gap is ensured between the Velcro and the fixing plate, so as to avoid mutual interference between the two in the connection effect and the pre-positioning effect.

[0016] Preferably, the first connector is a first rivet, the second connector is a second rivet, one end of the first rivet and the second rivet are arc-shaped ends, and the other end of the first rivet and the second rivet are expansion ends. The long side cover plate, the fixing plate and the covering layer are provided with a first through hole for the first rivet to pass through, and the short side cover plate and the ferromagnetic metal plate are provided with a second through hole for the second rivet to pass through.

[0017] By adopting the above technical solution, the first rivet and the second rivet serve to connect the covering layer and the fixing plate to the long side cover plate, and at the same time serve to fix the ferromagnetic metal plate to the short side cover plate.

[0018] Preferably, the ferromagnetic metal plate and the fixing plate are provided with positioning grooves for the expansion end to be inserted.

[0019] By adopting the above technical solution, the expansion end is prevented from protruding from the surface of the ferromagnetic metal plate and the fixing plate, thus avoiding affecting the thickness at that location and ensuring the connection between the hook and loop fastener face and the hook and loop fastener mother face.

[0020] Preferably, the long side cover plate and the short side cover plate are made of hollow plastic sheets.

[0021] By adopting the above technical solution, the structural strength of the box is improved, while the hot pressing of structures such as mounting slots and the mutual connection between the first rivet and the second rivet are facilitated.

[0022] Preferably, the long side cover plate is hot-pressed to form a mounting groove for embedding a fixing plate.

[0023] By adopting the above technical solution, the fixed plate is placed, while the relative distance between the long side cover plate and the short side cover plate is reduced, which facilitates the connection and positioning of the Velcro.

[0024] In summary, the cooperation between the hook and loop fastener side and the hook and loop fastener side achieves the final fixation; at the same time, the magnetic attraction between the magnetic fastener and the ferromagnetic metal plate further increases the stability before the final connection, forming a sequence of first magnetic alignment and then hook and loop adhesion, thus improving the fixation effect.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0032] Example 1:

[0033] like Figures 1 to 3 As shown, a type of tobacco leaf box with a built-in magnetic hook and loop fastener structure includes a box body 1. The box body 1 includes a long side cover 11 and a short side cover 12, which are made of hollow plastic sheets. Figure 1 This is a structural diagram of the box body 1 after the long side cover 11 is flipped outward. The short side cover 12 is symmetrically rotated and connected to both sides of the short side of the box body 1, and the long side cover 11 is symmetrically rotated and connected to both sides of the long side of the box body 1. When the box body 1 is closed, the long side cover 11 covers the short side cover 12. The bottom of the long side cover 11 is provided with a Velcro surface 21, and the top of the short side cover 12 is provided with a Velcro female surface 22. The Velcro surface 21 and the Velcro female surface 22 correspond to each other. The bottom of the long side cover 11 is provided with a fixing plate 31, and a covering layer 4 is provided on the fixing plate 31. A magnetic suction element 33 is provided between the fixing plate 31 and the covering layer 4.

[0034] like Figure 3 As shown, the connection between the covering layer 4 and the long side cover plate 11 is as follows: a first connector 34 is provided between the covering layer 4 and the fixing plate 31, and the first connector 34 fixes the covering layer 4 and the fixing plate 31 to the long side cover plate 11. A ferromagnetic metal plate 5 corresponding to the magnetic attractor 33 is provided on the short side cover plate 12, and a second connector 51 is provided on the ferromagnetic metal plate 5, and the second connector 51 fixes the ferromagnetic metal plate 5 to the bottom of the long side cover plate 11. In order to optimize the structure and simplify the processing technology, both the fixing plate 31 and the ferromagnetic metal plate 5 are made of stainless steel metal plates with the same size and thickness, and both the first connector 34 and the second connector 51 adopt a rivet structure.

[0035] like Figure 2 The diagram shown is an enlarged view of the fixing plate 31 after the surface covering layer is removed. In embodiment 1, the covering layer 4 consists of two parts: a Teflon upper layer 41 and an adhesive lower layer 42. The covering layer 4 extends to the outside of the fixing plate 31 and is connected to the bottom of the long side cover plate 11. The covering layer 4 is rectangular and extends along the width direction of the fixing plate 31. At the same time, in order to avoid mutual interference between magnetic attraction and adhesion, an adhesive area 43 is formed between the Velcro surface 21 and the fixing plate 31 for the covering layer 4 to be bonded. The covering layer 4 covers the edge of the fixing plate 31.

[0036] like Figures 1 to 3 As shown, in order to ensure the connection process of magnetic attraction before bonding, the sum of the thicknesses of the fixing plate 31, magnetic attractor 33, covering layer 4 and ferromagnetic metal plate 5 is greater than the sum of the thicknesses of the hook and loop fastener face 21 and the hook and loop fastener mother surface 22. That is, before the hook and loop fastener is bonded, the magnetic attractor 33 is first connected to the ferromagnetic metal plate 5.

[0037] like Figures 1 to 3As shown, the specific structure of the hook and loop fastener is as follows: the width of the hook and loop fastener sub-face 21 is equal to the width of the hook and loop fastener mother face 22, the length of the hook and loop fastener sub-face 21 is less than half the length of the hook and loop fastener mother face 22, the hook and loop fastener mother face 22 is located in the middle of the short side cover plate 12, and the hook and loop fastener sub-face 21 and the hook and loop fastener mother face 22 are arranged in a rectangle.

[0038] like Figure 3 As shown, in order to ensure the connection effect between the fixing plate 31 and the ferromagnetic metal plate 5 and the cover plate, the first connector 34 is the first rivet, and the second connector 51 is the second rivet. One end of the first rivet and the second rivet is an arc-shaped end 61, and the other end of the first rivet and the second rivet is an expansion end 62. The long side cover plate 11, the fixing plate 31 and the covering layer 4 are provided with a first through hole 35 for the first rivet to pass through, and the short side cover plate 12 and the ferromagnetic metal plate 5 are provided with a second through hole 52 for the second rivet to pass through. At the same time, the ferromagnetic metal plate 5 and the fixing plate 31 are provided with a positioning groove 63 for the expansion end 62 to be embedded, so as to prevent the connector from protruding at the Velcro bonding position.

[0039] Working principle:

[0040] The magnetic component 33 is embedded in the bottom of the long side cover plate 11 through the fixing plate 31 and the covering layer 4, and is connected and fixed by the first rivet. The ferromagnetic metal plate 5 is fixed on the short side cover plate 12 by the second rivet to ensure accurate magnetic alignment. The total thickness of the magnetic component is greater than the thickness of the hook and loop fastener, which ensures priority contact of the magnetic components and reduces the positioning error of the hook and loop fastener. At the same time, the Teflon layer also prevents the hook and loop fastener from sticking. The length of the hook and loop fastener side 21 is less than half of the length of the side surface, which saves materials and ensures effective bonding area. The rivet connection method prevents the fixing plate 31 and the ferromagnetic metal plate 5 from becoming loose.

[0041] Example 2:

[0042] like Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is that, in order to further reduce the distance between the long side cover plate 11 and the short side cover plate 12 in the height direction, a mounting groove 32 for the fixing plate 31 to be embedded is formed on the long side cover plate 11 by hot pressing.
