Description
Technical Field
[0001] This application relates to the technical field of packaging boxes, and in particular to a double-layer storage box that is easy to pull out. Background Technology
[0002] Currently, storage boxes are a common storage tool widely used in various scenarios such as homes, offices, and travel. They help people organize and store various items in an orderly manner, making spaces tidier and items easier to find. Especially when traveling, storage boxes become a powerful assistant in organizing luggage, as people categorize and place various small items in storage boxes for better management and carrying. However, with the increasing diversification and sophistication of storage needs, existing storage boxes have gradually revealed some shortcomings in their functional design, making it difficult to meet people's needs in different scenarios.
[0003] In related technologies, a storage box includes a box body, wherein the upper side of the box body has a storage cavity for placing miscellaneous items, and a box cover for sealing the opening of the storage cavity is detachably installed on the box body; one side of the box cover is rotatably connected to the edge of the opening of the storage cavity, and the other side of the box cover is locked to the other edge of the opening of the storage cavity by a locking block structure; in use, the user can first release the locking engagement between the box cover and the opening of the storage cavity, and then put all items into the storage cavity.
[0004] In the aforementioned related technologies, when traveling, due to limited suitcase space, users often place various small items together in the storage compartment of the storage box. When a particular item needs to be used, because all the items are mixed together, users have to spend a lot of time searching through the storage compartment. This not only reduces the efficiency of use, but may also lead to damage or loss of items due to frequent searching, indicating room for improvement. Summary of the Invention
[0005] The purpose of this application is to provide a pull-out double-layer storage box to solve the problem in the above-mentioned related technologies where users place all items in one storage cavity, resulting in a lot of time being spent searching for certain items, thus reducing usage efficiency.
[0006] The double-layer storage box that is easy to pull out, as provided in this application, adopts the following technical solution: A pull-out double-layer storage box includes a box body and a lid rotatably connected to the box body. The upper side of the box body has a first storage cavity for placing items, and the lid seals the opening of the first storage cavity. A mounting cavity is located below the first storage cavity on the vertical side of the box body. A pull-out box slides within the mounting cavity, and the upper side of the pull-out box has a second storage cavity for placing items. A traction member is provided on the outer side of the pull-out box away from the box body, and a connector is provided inside the box body to connect the pull-out box and the lid. When the pull-out box is pulled out from the second storage cavity, the connector controls the lid to rotate away from the traction member.
[0007] By adopting the above technical solution, users can use the first storage compartment to store small and easily lost items such as jewelry, while the second storage compartment can accommodate relatively larger and frequently used items such as cosmetics. This layered storage method allows different types of items to be placed in their respective locations, effectively avoiding the situation of items being mixed and piled up, greatly improving the orderliness of item management. Users can quickly locate items when looking for them, saving a lot of searching time and improving daily usage efficiency.
[0008] Optionally, the bottom wall of the first storage cavity away from the opening of the mounting cavity is provided with a connection port communicating with the mounting cavity. The connecting component includes a connecting plate and a flexible connecting strip. The connecting plate is fixed on the inner side of the box cover. One side of the connecting plate passes through the connection port and can be inserted into the mounting cavity. One end of the flexible connecting strip is fixedly connected to the side of the connecting plate inserted into the mounting cavity, and the other end is fixedly connected to the side of the pull-out box away from the traction component.
[0009] By adopting the above technical solution, when the user pulls the pull-out box, the pull-out box moves the flexible connecting belt, which in turn pulls the connecting plate, and then drives the lid to rotate through the connecting plate, thus realizing the synchronous action of pulling out the pull-out box and opening the lid. This design does not require an additional power source or complex mechanical structure, and achieves efficient linkage through simple component combination, which not only ensures the smoothness of operation, but also reduces production costs and failure rate.
[0010] Optionally, a partition plate for separating the first storage cavity and the installation cavity is fixed inside the box.
[0011] By adopting the above technical solution, the divider provides a clear and distinct boundary between the two cavities, making the storage of items more organized and allowing users to quickly distinguish the storage locations of different items, thus avoiding confusion.
[0012] Optionally, the traction component is a flexible pull strap fixed to the outer surface of the pull-out box, which can pull the pull-out box out of the mounting cavity.
[0013] By adopting the above technical solution, the flexible pull strap is soft and elastic, making it comfortable for users to pull without requiring much force. A gentle tug is all it takes to move the pull-out box. Moreover, during the pulling process, the flexible connecting strip responds simultaneously, quickly releasing the lid from the first storage cavity. The whole process is smooth and natural.
[0014] Optionally, the side of the lid facing the traction member is fixedly provided with an extension plate facing the outer side of the pull-out box, and a limiting member is fixedly provided on the extension plate; the traction member is a limiting plate rotatably connected to the outer side of the pull-out box; the extension plate can be detachably connected to the limiting plate through the limiting member when the lid blocks the first storage cavity.
[0015] By adopting the above technical solution, when the storage box is in the closed state, this connection can effectively prevent the lid from opening accidentally and avoid the contents from falling out due to loosening of the lid caused by shaking or collision; at the same time, it also ensures the fixed position of the pull-out box inside the storage box, preventing it from sliding at will, making the entire storage box more stable and reliable during use, and improving the overall quality and service life of the storage box.
[0016] Optionally, the limiting member is a limiting block fixed on the side of the extension plate away from the lid, and the limiting plate has a limiting slot; the limiting block can be embedded into the limiting slot when the limiting plate is rotated to the vertically upward state.
[0017] By adopting the above technical solution, when the lid seals the first storage cavity, the limiting block is precisely inserted into the limiting slot, and the two work together to form a reliable locking connection. This connection method can effectively resist the impact and shaking of external forces, prevent the lid from opening accidentally when the storage box is moved or collided, and ensure the safe storage of the internal items.
[0018] Optionally, the side edge of the limiting block away from the extension plate is chamfered; the opening edge of the limiting slot is a guide slope.
[0019] By adopting the above technical solution, the chamfer can guide the limiting plate to approach the limiting block more smoothly, avoiding the situation where the limiting plate gets stuck or shifts when inserted due to the sharp right angle of the edge of the limiting block; when the user rotates the limiting plate to a position close to the limiting block, the guide slope can automatically guide the limiting block to smoothly enter the limiting slot.
[0020] Optionally, a first magnetic block is embedded on the side of the limiting block away from the extension plate, and a second magnetic block is embedded on the inner wall of the limiting slot. When the limiting block is embedded in the limiting slot, the first magnetic block abuts against the second magnetic block and attracts each other.
[0021] By adopting the above technical solution, when the user rotates the limiting plate upward to insert the limiting block into the limiting slot, the first magnetic block and the second magnetic block abut against each other and attract each other, thus preventing the limiting block from coming out of the limiting slot due to accidental contact.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When traveling, users can use the first storage compartment to store small and easily lost items such as jewelry, while the second storage compartment can hold relatively larger and frequently used items such as cosmetics. This layered storage method allows different types of items to have their own place, effectively avoiding the situation of items being mixed and piled up, greatly improving the orderliness of item management. Users can quickly locate items when looking for them, saving a lot of searching time and improving daily usage efficiency. 2. When the lid seals the first storage cavity, the limiting block is precisely inserted into the limiting slot, and the two work together to form a reliable locking connection. This connection method can effectively resist the impact and shaking of external forces, and prevent the lid from opening accidentally when the storage box is moved or collided, ensuring the safe storage of the internal items.

[0026] The present application will be further described in detail below with reference to all the accompanying drawings.
[0027] Example 1: Reference Figure 1 , Figure 2 and Figure 3 A double-layer storage box that is easy to pull out includes a box body 1 and a box cover 2 rotatably connected to the box body 1; wherein the upper side of the box body 1 has a first storage cavity 11 for placing items, and the box cover 2 is used to seal the opening of the first storage cavity 11; and an installation cavity 12 located below the first storage cavity 11 is provided on the vertical side of the box body 1. The installation cavity 12 is slidably provided with a pull-out box 3, and the upper side of the pull-out box 3 is provided with a second storage cavity 31 for placing items; a partition plate 4 for separating the first storage cavity 11 and the installation cavity 12 is fixedly installed inside the box body 1; a traction member 5 is provided on the outer side of the pull-out box 3 away from the box body 1, and a connecting member 6 for connecting the pull-out box 3 and the box cover 2 is provided inside the box body 1. When the user pulls the pull-out box 3 out of the mounting cavity 12 using the traction component 5, the connecting component 6 will simultaneously control the box cover 2 to rotate away from the traction component 5; at this time, the user can place jewelry in the first storage cavity 11 and cosmetics and other items in the second storage cavity 31 of the pull-out box 3 to achieve layered storage.
[0028] Reference Figure 2 , Figure 3 and Figure 4 The bottom wall of the first storage cavity 11 away from the opening of the mounting cavity 12 has a connection port 13 that communicates with the mounting cavity 12. The connection port 13 is formed by the inner wall of the box body 1 and the partition plate 4. The connecting member 6 includes a connecting plate 61 and a flexible connecting strip 62. The connecting plate 61 is fixedly installed on the bottom side of the box cover 2 near the first storage cavity 11, and one side of the connecting plate 61 can be inserted into the mounting cavity 12 after passing through the connection port 13. One end of the flexible connecting strip 62 is fixedly connected to the side of the connecting plate 61 inserted into the mounting cavity 12, and the other end is fixedly connected to the side of the pull-out box 3 away from the traction member 5; the traction member 5 is a flexible pull strip 51 fixedly installed on the outer side of the pull-out box 3; when the user pulls the flexible pull strip 51 to move the pull-out box 3 away from the connecting port 13, the flexible connecting strip 62 will move synchronously, thereby driving the box cover 2 to rotate, releasing the blockage of the first storage cavity 11, making it convenient for the user to store and retrieve items.
[0029] The implementation principle of this application embodiment is as follows: When a user needs to place items, they can pull the flexible pull strap 51, causing the pull-out box 3 to move away from the connecting port 13. The flexible connecting strap 62 moves synchronously with the pull-out box 3, causing the connecting plate 61 to rotate the box cover 2 away from the traction member 5, thus releasing the seal on the first storage cavity 11. At this time, the user can put jewelry into the first storage cavity 11 and cosmetics into the second storage cavity 31 of the pull-out box 3 to achieve layered storage. After the items are placed, the user pushes the pull-out box 3 back into the mounting cavity 12. The box cover 2 rotates in the opposite direction under the action of the flexible connecting strap 62, resealing the opening of the first storage cavity 11 to ensure the safe storage of items.
[0030] Example 2: Reference Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that an extension plate 7 facing the outer side of the pull-out box 3 is integrally formed on the side of the box cover 2 facing the traction member 5, wherein a limiting member 71 is provided on the extension plate 7; the traction member 5 is a limiting plate 52 rotatably connected to the outer side of the pull-out box 3. When the lid 2 is in the state of sealing the first storage cavity 11, the extension plate 7 can be fixedly connected to the limiting plate 52 through the limiting member 71, so that the lid 2 is firmly fixed, thus preventing items from falling out accidentally.
[0031] Reference Figure 6 , Figure 7 and Figure 8 The limiting member 71 is a limiting block 711 integrally formed on the side of the extension plate 7 away from the box cover 2, and the limiting plate 52 has a limiting slot 521; the side edge of the limiting block 711 away from the extension plate 7 is chamfered 7111, and the opening edge of the limiting slot 521 is a guide slope 5211. When a user needs to place an item, simply rotate the limiting plate 52 away from the lid 2 to release its fixing effect on the lid 2; then, the user can pull the limiting plate 52 to pull out the pull-out box 3 for easy placement of various items. After the items are placed, the user can rotate the limiting plate 52 towards the lid 2 to insert the limiting block 711 into the limiting slot 521. The chamfer 7111 of the limiting block 711 and the guide slope 5211 of the limiting slot 521 make the insertion process smoother. When the box 1 is overturned, the lid 2 will not be opened due to the collision, ensuring the safe storage of the items.
[0032] Reference Figure 6 and Figure 8 A first magnetic block 7112 is embedded on the side of the limiting block 7 away from the extension plate 7, and a second magnetic block 5212 is embedded on the inner wall of the limiting slot 521. When the user rotates the limiting plate 52 upward to insert the limiting block 711 into the limiting slot 521, the first magnetic block 7112 and the second magnetic block 5212 abut against each other and attract each other, which can prevent the limiting block 711 from coming out of the limiting slot 521 due to accidental contact.
[0033] The implementation principle of this application embodiment is as follows: In the initial state, the lid 2 blocks the first storage cavity 11, the limiting plate 52 is in a vertically upward position, and the limiting block 711 can be inserted into the limiting slot 521. At this time, the lid 2 is firmly fixed to prevent items from falling out accidentally. When the user wants to place an item, the user rotates the limiting plate 52 away from the lid 2 to release its fixation on the lid 2, and then pulls the limiting plate 52 to pull out the pull-out box 3. After the item is placed, the user closes the pull-out box 3 and rotates the limiting plate 52 to allow the limiting block 711 to re-insert into the limiting slot 521, so that the storage box returns to a stable state, ensuring that the lid will not be opened due to collision when the storage box is overturned, thus ensuring the safe storage of items.
