Description

Technical Field

[0001] This utility model relates to the field of folding box technology, and in particular to a rotating structure for a storage box. Background Technology

[0002] Storage boxes are common household products that can store various items. When not in use, they can be folded up for storage to save space, making them very convenient to use. However, existing storage boxes still have some problems with the connection structure between their various components.

[0003] The rotating and folding structures in existing storage boxes are often simple in structure and not very strong. They are prone to falling apart in actual use, especially when faced with bumps during transportation and external impacts. The connecting parts are more likely to detach, making the entire storage box very unstable and with a short service life. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to improve the stability of the rotating structure of the storage box. In order to solve the above technical problem, this utility model provides a rotating structure for a storage box, including a first plate and a second plate that are rotatably connected. The first plate includes a rotating cavity, and the second plate includes a rotating rod that is inserted into the rotating cavity.

[0005] The rotating rod includes a main body, which includes a first side surface; the first side surface is provided with a first limiting protrusion, and the rotating cavity is provided with a second limiting protrusion. The first limiting protrusion is used to abut against the second limiting protrusion when the first plate and the second plate are folded, so as to restrict the movement of the rotating rod in the rotating cavity along the axis of the rotating cavity.

[0006] Preferably, the rotating rod further includes a limiting block, which is used to abut against the second limiting protrusion when the first plate and the second plate are unfolded, so as to restrict the movement of the rotating rod in the rotating cavity along the axis of the rotating cavity.

[0007] Preferably, the rotating cavity includes a first cavity and a second cavity, the rotating rod includes two parallel connecting rods, the connecting rods are fixedly connected to the second plate, the main body is disposed between the two connecting rods, the connecting rods are inserted into the first cavity, and the main body is inserted into the second cavity.

[0008] Preferably, a limiting baffle is provided between the first cavity and the second cavity, and the limiting block abuts against the limiting baffle to restrict the movement of the main body in the second cavity along the main body axis.

[0009] Preferably, multiple rotating cavities and rotating rods are provided.

[0010] Preferably, the first limiting protrusion includes a first guiding surface and a first abutting surface, and the second limiting protrusion includes a second guiding surface and a second abutting surface. The first guiding surface is used to cooperate with the second guiding surface to guide the body to move within the second cavity until the second abutting surface is positioned opposite to the first abutting surface. The first abutting surface is used to abut against the second abutting surface to limit the range of movement of the body.

[0011] Preferably, two second limiting protrusions are provided opposite to each other on the inner sidewall of the second cavity.

[0012] Preferably, the main body further includes a second side surface, which is disposed opposite to the first side surface; the distance from the first side surface to the second side surface is less than the diameter of the main body and greater than the distance between the two limiting protrusions.

[0013] Preferably, the two sides of the limiting block are coplanar with the first side and the second side, respectively.

[0014] Preferably, the corner of the limiting block on the side away from the main body is rounded.

[0015] Compared with the prior art, the rotating storage box structure provided in this embodiment of the present invention has the following advantages:

[0016] The storage box has two panels that can be folded or unfolded. The unfolded state is generally the usage state of the storage box, while the folded state is the storage state of the storage box, and also the state for installation and disassembly of the two panels. In traditional solutions, the connection between the panels is prone to loosening in the folded state, especially under external vibration and impact, the connection between the panels is more likely to break, which can cause the storage box to fall apart during transportation after being folded and stored. In this utility model, a first limiting protrusion is provided on the first side of the rotating rod, and a second limiting protrusion is provided in the rotating cavity. On the one hand, the first side setting allows the main body of the rotating rod to be smoothly inserted into the rotating cavity, and the two panels can be rotated and connected normally. On the other hand, the cooperation of the first limiting protrusion and the second limiting protrusion restricts the range of movement of the rotating rod in the folded state of the two panels, preventing the main body of the rotating rod from detaching from the rotating cavity under external vibration or impact, thereby preventing the storage box from falling apart.

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] like Figures 1 to 4 As shown, a preferred embodiment of the present invention provides a storage box rotating structure, which includes a first plate 1 and a second plate 2 rotatably connected. The first plate 1 includes a rotating cavity 3, and the second plate 2 includes a rotating rod 4, which is inserted into the rotating cavity 3.

[0026] The rotating rod 4 includes a main body 41, which includes a first side surface 411. The first side surface 411 is provided with a first limiting protrusion 42, and the rotating cavity 3 is provided with a second limiting protrusion 31. The first limiting protrusion 42 is used to abut against the second limiting protrusion 31 when the first plate 1 and the second plate 2 are folded, so as to restrict the movement of the rotating rod 4 in the rotating cavity 3 along the axis of the rotating cavity 3.

[0027] Specifically, in the field of storage boxes, storage boxes include two states: folded and unfolded. In the unfolded state, the panels are perpendicular to each other, while in the folded state, the panels are rotated and folded to form a nearly parallel structure, thus reducing the storage space of the box. The panels are generally installed in the folded state to avoid affecting the stability of the connections between the panels in the unfolded state. However, existing technologies do not provide sufficient restraint measures for the connections between the panels in the folded state. This means that when the storage box is subjected to external impact or vibration after being folded, the connections between the panels are very easy to break, and the connection between the rotating rod 4 and the rotating cavity 3 can easily detach, leading to the storage box falling apart. In this embodiment, a first side surface 411 is first provided on the main body 41. The distance from the first side surface 411 to the other side of the main body 41 along the radial direction of the main body 41 is less than the diameter of the main body 41. During installation, the first side surface 411 can be made approximately parallel to the side wall of the rotating cavity 3. When the main body 41 is pressed down, the first limiting protrusion 42 passes over the second limiting protrusion 31 and is located below the second limiting protrusion 31. When the main body 41 is in the folded state and encounters external vibration or impact, the second limiting protrusion 31 will abut against the first limiting protrusion 42, thereby limiting the range of movement of the main body 41 and preventing the main body 41 from detaching from the rotating cavity 3. The storage box will fall apart when unfolded. When unfolded, the main body 41 rotates, at which point the first side 411 is approximately perpendicular to the side wall of the rotating cavity 3. The diameter of the main body 41 is greater than the distance from the top of the second limiting protrusion 31 to the other side wall of the rotating cavity 3. The second limiting protrusion 31 abuts against the main body 41, further restricting the range of movement of the main body 41, thereby preventing the main body 41 from detaching from the rotating cavity 3. This ensures that the connection between the panels will not break when folded, while ensuring normal installation and normal unfolding and use. This allows the structure of the storage box to remain stable when folded and will not fall apart due to external vibration or impact.

[0028] In some embodiments, the rotating rod 4 also includes a limiting block 43, which is used to abut against the second limiting protrusion 31 when the first plate 1 and the second plate 2 are unfolded, so as to restrict the movement of the rotating rod 4 in the rotating cavity 3 along the axis of the rotating cavity 3.

[0029] Specifically, the storage box has two states: folded and unfolded. In the folded state, the first limiting protrusion 42 and the second limiting protrusion 31 abut against each other, thereby restricting the movement of the main body 41 and preventing the main body 41 from detaching from the rotating cavity 3. In the unfolded state, although the movement of the main body 41 can be restricted by the abutment between the main body 41 and the second limiting protrusion 31, the overall structure of the main body 41 is roughly cylindrical, and its contact area with the second limiting protrusion 31 is too small, making the abutment very unstable and prone to slippage. It is also difficult to withstand external pulling force. Therefore, an additional limiting block 43 is set. The side of the square limiting block 43 abuts against the second limiting protrusion 31, thereby improving the stability of the abutment between the rotating rod 4 and the second limiting protrusion 31. At the same time, it also improves the overall structural strength of the storage box after unfolding. The abutment between the limiting block 43 and the second limiting protrusion 31 has a larger contact area, which can withstand greater pulling force, resulting in higher overall structural strength and greater stability.

[0030] In some embodiments, the rotating cavity 3 includes a first cavity 32 and a second cavity 33, and the rotating rod 4 includes two parallel connecting rods 44. The connecting rods 44 are fixedly connected to the second plate 2, and a main body 41 is provided between the two connecting rods 44. The connecting rods 44 are inserted into the first cavity 32, and the main body 41 is inserted into the second cavity 33.

[0031] Furthermore, a limiting baffle 34 is provided between the first cavity 32 and the second cavity 33, and the limiting block 43 abuts against the limiting baffle 34 to limit the movement range of the main body 41 within the second cavity 33.

[0032] Specifically, the connecting rod 44 is used to connect the main body 41 and the plate. The main body 41 drives the plate to rotate through the connecting rod 44, thereby adjusting the switching between the folded and unfolded states of the two plates. For the connecting plate and the main body 41, the rotating cavity 3 is divided into two parts: a first cavity 32 and a second cavity 33.

[0033] In addition, the limiting block 43 is set out to protrude from the main body 41. In actual use, in addition to limiting the movement of the main body 41 along the axis of the rotating cavity 3 to prevent the main body 41 from detaching from the second cavity 33, it is also necessary to limit the movement of the main body 41 along its axis to prevent the storage box structure from being unstable and prone to shaking when unfolded. Therefore, the limiting baffle 34 and the limiting block 43 are set. The contact between the two can limit the movement of the main body 41 of the rotating rod 4 along its axis, ensuring the stability of the overall structure of the storage box after it is unfolded.

[0034] In some embodiments, multiple rotating cavities 3 and rotating rods 4 are provided. Providing multiple rotating cavities 3 and rotating rods 4 ensures a more stable and smooth rotational connection between the two plates.

[0035] In some embodiments, the first limiting protrusion 42 includes a first guiding surface 421 and a first abutting surface 422, and the second limiting protrusion 31 includes a second guiding surface 311 and a second abutting surface 312. The first guiding surface 421 is used to cooperate with the second guiding surface 311 to guide the body 41 to move within the second cavity 33 until the second abutting surface is opposite to the first abutting surface 422. The first abutting surface 422 is used to abut against the second abutting surface 312 to limit the range of movement of the body 41.

[0036] Furthermore, two second limiting protrusions 31 are provided opposite to each other on the inner sidewall of the second cavity 33.

[0037] Specifically, both the first guide surface 421 and the second guide surface 311 are curved, while the first abutment surface 422 is planar. The second abutment surface 312, corresponding to the first abutment surface 422, is also planar. The curved structure of both the first guide surface 421 and the second guide surface 311 better guides the main body 41 to move downward along the axis of the second cavity 33. When the first guide surface 421 contacts the second guide surface 311, the first limiting protrusion 42 presses against the second limiting protrusion 31, causing the main body 41 to continue moving downward until the first abutment surface 422 and the second abutment surface 312 are positioned opposite each other. When encountering external impacts or vibrations, the second abutment surface 312 will abut against the first abutment surface 422, thereby restricting the movement of the main body 41 and preventing the main body 41 from detaching from the second cavity 33 in the folded state, thus ensuring the stability of the storage box structure.

[0038] Furthermore, in this embodiment, only the second abutment surface 312 of the second limiting protrusion 31 that is fixed to the first limiting protrusion 42 is flat, while the second abutment surface 312 of the other second limiting protrusion 31 is set as an arc surface to fit the arc structure of the main body 41, taking into account the flexibility of the rotation of the main body 41 and the flexibility of the storage box switching between the folded and unfolded states. Of course, in another embodiment, first limiting protrusions 42 are provided on both the first side 411 and the second side 412, and the two first limiting protrusions 42 correspond to the two second limiting protrusions 31.

[0039] In some embodiments, the main body 41 further includes a second side surface 412, which is disposed opposite to the first side surface 411; the distance between the first side surface 411 and the second side surface 412 is less than the diameter of the main body 41, and is greater than the distance between the two limiting protrusions.

[0040] Furthermore, the two sides of the limiting block 43 are coplanar with the first side 411 and the second side 412, respectively.

[0041] Furthermore, the corner of the limiting block 43 on the side away from the main body 41 is rounded.

[0042] Specifically, the design of the two sides allows the two plates to press down on the main body 41 more effectively during installation and connection. The main body 41 can then better pass over the second limiting protrusion 31 and move below it. Furthermore, in the unfolded state of the storage box, the second side 412 can also abut against the second contact surface 312 to restrict the movement of the main body 41. In addition, the limiting block 43 increases the contact area between the second side 412 and the second contact surface 312 in the unfolded state, thereby increasing the tensile force that the rotating rod 4 can withstand. This makes the entire connection structure more stable and reliable, stronger, and has a longer service life, and can adapt to environments with greater tensile forces. The rounded corners of the limiting block 43 also serve as a guide, allowing the main body 41 to move more effectively below the second limiting protrusion 31.

[0043] In summary, this utility model embodiment provides a storage box rotation structure. By setting a first limiting protrusion 42 on the main body 41 of the rotating rod 4, and cooperating with the second limiting protrusion 31 in the rotating cavity 3, the main body 41 can still be well restricted in the position of the second cavity 33 of the rotating cavity 3 when the storage box is in the folded state, preventing the main body 41 from leaving the second cavity 33. The setting of the limiting block 43 ensures that the main body 41 can also be well restricted in the unfolded state of the storage box. At the same time, it also improves the connection strength between the two first plates 1 and the second plate 2, and improves the stability of the overall structure.

[0044] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
