[0027] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0028] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present utility model are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence.

[0029] The orientation terms such as up, down, left, right, front, back, top, bottom, etc. (if any) involved in the description and claims of the present utility model are defined based on the positions of the structures in the accompanying drawings and the positions relative to each other, only for the sake of clarity and convenience of expressing the technical solution. It should be understood that the use of orientation terms should not limit the scope of protection claimed by the present utility model.

[0030] As Figures 1 to 4 shown, the embodiment of the present utility model provides a storage box, including a box body 1 and a box cover 2. The box cover 2 is located above the box body 1. One side of the box cover 2 and the box body 1 is rotatably connected through a hinge structure 3. The other side of the box cover 2 opposite to the box body 1 is locked to each other through a lock catch 4, so as to realize the opening and closing and locking of the box cover 2 and the box body 1. Among them, the lock catch 4 is a rolling lock catch. The lock catch 4 includes a body part 41 and a roller 42 sleeved on the body part 41. The body part 41 is made of metal material. The slender metal material has a certain elasticity when bent. The roller 42 is made of plastic material. The roller 42 can rotate relative to the body part 41, and the body part 41 is rotatably connected to the box body 1. When the box cover 2 and the box body 1 are closed, the roller 42 can press against the box cover 2 to lock the box cover 2 and the box body 1 to each other.

[0031] The storage box provided by the embodiment of the utility model adopts a rolling lock. The lock 4 includes a body part 41 and a roller 42 sleeved on the body part 41. The roller 42 can rotate relative to the body part 41. During the process of the lock 4 being buckled with the box cover 2, the roller 42 on the lock 4 can roll on the box cover 2, thereby reducing the frictional resistance between the lock 4 and the box cover 2 during the buckling process, achieving the effect of labor saving and improving the user experience.

[0032] As an implementation manner, the roller 42 is of a hollow structure, and the inner diameter of the roller 42 is slightly larger than the outer diameter of the body part 41, so that the roller 42 can rotate relative to the body part 41.

[0033] As Figure 1 and Figure 3 shown, as an implementation manner, the box cover 2 is provided with a clamping part 21. The top of the clamping part 21 is provided with a limiting groove 22 and a convex rib 23. The convex rib 23 is located on the side of the limiting groove 22 away from the center of the box cover 2. The roller 42 can roll over the convex rib 23 and snap into the limiting groove 22 after passing over the convex rib 23. Due to the blocking effect of the convex rib 23, without external force, the roller 42 is not easy to roll backward and disengage from the limiting groove 22, thereby realizing the locking between the lock 4 and the clamping part 21.

[0034] As Figure 1 and Figure 3 shown, as an implementation manner, a non-straight surface 231 is provided on the side of the convex rib 23 away from the limiting groove 22. The non-straight surface 231 can be an inclined surface or an arc surface, etc. By providing the non-straight surface 231 on the convex rib 23, when the roller 42 interferes with the convex rib 23, the roller 42 can roll along the non-straight surface 231 and easily pass over the convex rib 23, thereby achieving the effect of labor saving during the buckling process of the lock 4.

[0035] As Figure 1 and Figure 3 shown, as an implementation manner, the outer side wall of the clamping part 21 is flush with the outer side wall of the edge of the box cover 2, thereby improving the aesthetics of the box cover 2 (that is, the clamping part 21 does not protrude separately from the edge of the box cover 2). Avoidance grooves 24 are provided on both sides of the clamping part 21 on the edge of the box cover 2. The avoidance grooves 24 are used to avoid the body part 41 of the lock 4 to prevent the body part 41 from interfering with the edge of the box cover 2 and causing the lock 4 to be unable to be buckled.

[0036] As Figure 1 and Figure 3 shown, as an implementation manner, a mounting part 11 protrudes from the position of the box body 1 corresponding to the clamping part 21. The body part 41 is rotatably connected to the mounting part 11. The outer side wall of the mounting part 11 is flush with the outer side wall of the clamping part 21, thereby improving the aesthetics of the storage box.

[0037] As Figure 1As shown, as an implementation manner, a rubber ring 25 is provided at the connection between the installation part 11 and the main body part 41, facilitating the roller 42 to cross over the convex rib 23. Specifically, when the roller 42 crosses over the convex rib 23, the rubber ring 25 is compressed, and the lock catch 2 can be pulled upwards towards the box cover 2, enabling the roller 42 to easily cross over the convex rib 23. When the roller 42 crosses over the convex rib 23 and snaps into the limit groove 22, since the height of the limit groove 22 is lower than that of the convex rib 23, the lock catch 4 no longer presses the rubber ring 25, and the rubber ring 25 rebounds, causing the lock catch 4 to fall back.

[0038] The lock catch 4 structure provided by the present utility model can relatively easily cross over the convex rib 23 and lock the box body 1 and the box cover 2 after snapping into the limit groove 22. The main reasons are as follows: 1. The main body part 41 of the lock catch 4 is made of a metal material and has a certain elasticity after being bent; 2. A rubber ring 25 is provided to further provide elastic compression; 3. Most importantly, a rotatable roller 42 is provided to change the static friction into sliding friction, reducing the frictional force between the roller 42 and the convex rib 23.

[0039] As Figure 1 、 Figure 3 and Figures 6 to 8 shown, as an implementation manner, the main body part 41 includes a main body portion 410 having a C-shaped structure, two extension portions 414 respectively connected to opposite ends of the main body portion 410, and two joint portions 415 respectively connected to the two extension portions 414. The roller 42 is sleeved on the main body portion 410 and can rotate relative to the main body portion 410. Both of the two joint portions 415 are rotatably connected to the box body 1 (specifically, the two joint portions 415 are respectively rotatably connected to opposite sides of the installation part 11).

[0040] Among them, the main body portion 410 includes a recessed section 411 for sleeving the roller 42, protruding sections 412 located on both sides of the recessed section 411, and vertical sections 413 located on both sides of the recessed section 411. The protruding sections 412 on both sides are respectively connected to the recessed section 411 on both sides, the vertical sections 413 on both sides are respectively connected to the protruding sections 412 on both sides, and the two extension portions 414 are respectively connected to the vertical sections 413 on both sides. The recessed section 411, the protruding sections 412, and the vertical sections 413 are all in the same plane. The recessed section 411 is recessed towards the joint portion 415 relative to the protruding section 412. Since the roller 42 is sleeved on the recessed section 411, both sides of the roller 42 can be limited by the protruding sections 412, thereby preventing the roller 42 from moving significantly left and right on the recessed section 411.

[0041] As Figure 1 、 Figure 3 and Figures 6 to 8As shown, as an embodiment, the extension portion 414 is bent toward the side closer to the center of the box body 1 compared to the main body portion 410, and the included angle a between the extension portion 414 and the main body portion 410 is 90° to 175°. The setting of the extension portion 414 facilitates the outward protrusion of the roller 42. When the roller 42 is located in the limit groove 22, the roller 42 is perpendicular to the limit groove 22, which is convenient for fixing the roller 42.

[0042] As Figure 1 and Figure 3 shown, as an embodiment, a plurality of latches 4 (two are shown in the figure) are provided on the box body 1, and the plurality of latches 4 are arranged at intervals; a plurality of engaging portions 21 are provided on the lid 2, and the plurality of engaging portions 21 respectively correspond to the plurality of latches 4, and the plurality of latches 4 can be respectively engaged and locked with the plurality of engaging portions 21.

[0043] As Figure 2 and Figure 4 shown, as an embodiment, the hinge structure 3 includes:

[0044] A rotating shaft 31 is provided on the box body 1; the rotating shaft 31 is spaced from the outer side wall of the box body 1;

[0045] A first limiting portion 33 and two hook portions 32 located below the first limiting portion 33, the hook portions 32 are L-shaped structures, the first limiting portion 33 is located on the opening side of the hook portions 32, and the first limiting portion 33 and the hook portions 32 are spaced up and down; the first limiting portion 33 and the two hook portions 32 are both provided on the lid 2;

[0046] The rotating shaft 31 is rotatably installed between the first limiting portion 33 and the hook portions 32, thereby realizing the rotational connection between the lid 2 and the box body 1.

[0047] Specifically, by providing the hook portion 32 and the first limiting portion 33, the hook portion 32 and the first limiting portion 33 are used to limit the rotating shaft 31 from both sides respectively, that is, the rotating shaft 31 is clamped between the first limiting portion 33 and the hook portion 32, and the hook portion 32 is hooked to the rotating shaft 31, thereby preventing the hook portion 32 and the first limiting portion 33 from detaching from the rotating shaft 31 during rotation. At the same time, this structure in which the hook portion 32 and the first limiting portion 33 cooperate with the rotating shaft 31 to rotate can facilitate installation and disassembly, that is, the hinge structure 3 is a detachable structure; during installation, only need to make the lid 2 in a standing state, then align the gap between the hook portion 32 and the first limiting portion 33 with the rotating shaft 31, and then move the lid 2 downward to embed the rotating shaft 31 between the hook portion 32 and the first limiting portion 33, so that the hook portion 32 and the first limiting portion 33 can be engaged with the rotating shaft 31. The hinge structure 3 not only has a simple structure, but also can be easily installed and disassembled. During transportation, the lid 2 can be separated from the box body 1, and then multiple box bodies 1 and multiple lids 2 can be nested together for packaging and transportation respectively, thereby greatly improving the utilization rate of the packaging and transportation space and saving transportation costs.

[0048] As Figure 2 and Figure 4 shown, as an implementation manner, the two hook portions 32 are arranged at intervals left and right, and at least a part of the first limiting portion 33 is located above the gap 320 between the two hook portions 32; in this way, the two hook portions 32 can better cooperate with the first limiting portion 33 to limit the rotating shaft 31 at the same time, improving the stability of the structure.

[0049] As Figure 2 and Figure 4 shown, as an implementation manner, the hinge structure 3 further includes a second limiting portion 34, the second limiting portion 34 is provided on the box body 1, the outer surface of the second limiting portion 34 away from the box body 1 is parallel to the outer surface of the box body 1 (the second stop surface 341), and the bottom surface (the first stop surface 331) of the first limiting portion 33 close to the hook portion 32 is parallel to the surface of the lid 2 close to the box body 1 side. Thus, when rotating the rotating shaft 31, when the bottom surface of the first limiting portion 33 is parallel to the outer surface of the second limiting portion 34, the box body 1 and the lid 2 do not interfere with each other in the parallel direction of the first limiting portion 33 and the second limiting portion 34 (in this embodiment, at this time, the lid 2 is in a standing state). At this time, the rotating shaft 31 only needs to overcome the resistance of the hook portion 32 to install or separate the lid 2 and the box body 1; after the hinge structure 3 is installed, the first limiting portion 33 abuts against the second limiting portion 34, and the rotating shaft 31 abuts against the hook portion 32, thereby realizing the limiting of the rotating shaft 31 by the hook portion 32 and the first limiting portion 33 to prevent the hook portion 32 and the first limiting portion 33 from detaching from the rotating shaft 31 during rotation. Of course, in other embodiments, it may also be that the first limiting portion 33 directly abuts against the rotating shaft 31 for limiting.

[0050] As Figure 2 and Figure 4 shown, as an implementation manner, when the lid 2 rotates relative to the box body 1, the first limiting portion 33 can rotate relative to the second limiting portion 34. The second limiting portion 34 is provided with an arc surface 342 at the position for contacting the first limiting portion 33, so that the first limiting portion 33 can rotate more smoothly along the arc surface 342 relative to the second limiting portion 34. Of course, in other embodiments, an arc surface may also be provided at the position of the first limiting portion 33 for contacting the second limiting portion 34.

[0051] As Figure 2 、 Figure 4 and Figure 5 shown, as an implementation manner, the first limiting portion 33 is provided with a first stop surface 331, and the second limiting portion 34 is provided with a second stop surface 341; when the lid 2 rotates relative to the box body 1 to the standing state, the second stop surface 341 abuts against the first stop surface 331 (abutting against each other in parallel), so that the lid 2 can be kept in the standing state.

[0052] As Figure 2 and Figure 4 shown, as an implementation manner, the rotating shaft 31 includes two half shafts 311, and the second limiting portion 34 is located between the two half shafts 311; the hinge structure 3 further includes a lug 35 provided on the box body 1, one end of each half shaft 311 is fixedly connected to the lug 35, and the other end of each half shaft 311 is fixedly connected to the second limiting portion 34. The two hook portions 32 are respectively hooked to the two half shafts 311, and the two hook portions 32 are respectively located on opposite sides of the second limiting portion 34.

[0053] As Figure 2 and Figure 4 shown, as an implementation manner, the first limiting portion 33 and the hook portion 32 are of an integral structure with the lid 2 (specifically, integrally formed by injection molding), and the rotating shaft 31, the second limiting portion 34 and the lug 35 are of an integral structure with the box body 1 (specifically, integrally formed by injection molding). This integral hinge structure 3 does not require an additional rotating shaft, not only has a simple structure, is convenient to manufacture, has a low cost, but also is convenient for installation and disassembly.

[0054] As Figure 2 and Figure 4 shown, as an implementation manner, the number of the hinge structures 3 is multiple (shown as three in the figure), and the multiple hinge structures 3 are arranged at intervals on the box body 1 and the lid 2.

[0055] The storage box provided by the embodiment of the present utility model adopts a rolling latch. The latch 4 includes a body part 41 and a roller 42 sleeved on the body part 41. The roller 42 can rotate relative to the body part 41. During the process of latching with the box cover 2, the roller 42 on the latch 4 can roll on the box cover 2, thereby reducing the frictional resistance between the latch 4 and the box cover 2 during the latching process, achieving the effect of labor saving and improving the user experience. At the same time, a detachable integrated hinge structure 3 is adopted, which not only has a simple structure, is convenient to manufacture, and has a low cost, but also is convenient for installation and disassembly, facilitating the nested packaging of the storage box, and can greatly improve the utilization rate of the packaging and transportation space and save the transportation cost.

[0056] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
