Abstract
Description
Technical Field
[0001] This application relates to the technical field of packaging boxes, and in particular to a pull-out drawer box. Background Technology
[0002] As modern lifestyles and work styles continue to evolve, storage boxes are increasingly designed to be multifunctional, efficient, and convenient.
[0003] Traditional drawer boxes typically use a single drawer design, requiring users to open each drawer individually, which is extremely inconvenient when multiple items need to be accessed simultaneously. For applications requiring multiple drawers, the traditional solution is to use individual rails and sliding grooves for each drawer. However, multiple independent rails and grooves increase the structural complexity of the drawer box, leading to greater manufacturing and installation difficulties. Furthermore, the independent rail design makes drawer disassembly and assembly cumbersome, and maintenance and repair are not convenient. Utility Model Content
[0004] To facilitate the simultaneous pulling out of multiple drawers, a pull-out linked drawer box is provided.
[0005] The above-mentioned objective of this application is achieved through the following technical solution:
[0006] A pull-out linked drawer box includes a box frame with a through-hole movable slot. A first inner box and a second inner box are installed in the movable slot. A fixing plate is fixed on the side wall of the box frame. The fixing plate includes a fixing surface and a transmission surface. The fixing surface is fixedly connected to the side wall of the box frame. The transmission surface is parallel to the bottom surface of the box frame. A synchronous belt is sleeved on the transmission surface along the slot direction. The synchronous belt is slidably connected to the transmission surface. The first inner box is located on the side of the synchronous belt facing away from the bottom surface of the box frame. The bottom of the first inner box is fixedly connected to the synchronous belt. A connecting plate is fixed on the side of the synchronous belt facing the bottom surface of the box frame. The connecting plate is parallel to the synchronous belt. The other end of the connecting belt is fixedly connected to the bottom of the second inner box.
[0007] By adopting the above technical solution, since the first inner box and the second inner box are relatively parallel and share the same movable slot, the first inner box and the second inner box can move synchronously through the linkage of the synchronous belt, making the operation more convenient and the overall space occupied is smaller. At the same time, the linkage structure allows the two inner boxes to move at the same time, saving operation time and improving storage efficiency.
[0008] Optionally, the first inner box and the second inner box are fitted together.
[0009] By adopting the above technical solution, the first inner box and the second inner box fit together when closed, leaving no gap between them. This allows the space inside the box frame to be fully utilized, increasing the space that the first and second inner boxes can hold and improving the practicality of the product.
[0010] Optionally, the two ends of the transmission surface are provided with inwardly recessed relief grooves, and the two ends of the synchronous belt are respectively located in the two relief grooves.
[0011] By adopting the above technical solution, since both ends of the conveyor belt are located in the relief groove, when the first inner box and the second inner box are pulled out, the conveyor belt can effectively limit the movement range of the inner box and prevent the inner box from being pulled out excessively. This not only protects the integrity of the inner box and the transmission system, but also avoids items falling or structural damage caused by the inner box being pulled out excessively.
[0012] Optionally, the two sides of the connecting plate abut against the timing belt and the bottom surface inside the box frame, respectively.
[0013] By adopting the above technical solution, the contact between the connecting plate and the synchronous belt ensures its linkage with the first inner box, and the contact with the bottom surface of the box frame enables the stable movement of the connecting plate, ensuring the normal operation of the linkage function of the inner box and avoiding transmission problems caused by loosening or sliding of the connecting plate.
[0014] Optionally, a pull cord is fixed to the side of the first inner box located outside the box frame.
[0015] By adopting the above technical solution, a pull cord is added to make it easier for users to pull out the first inner box, simplifying the operation steps and improving the user's experience of pulling out the first inner box.
[0016] Optionally, a rubber pad is fixed to the bottom of the side of the first inner box where the pull cord is installed, and the rubber pad abuts against the bottom surface of the box frame.
[0017] By adopting the above technical solution, by fixing a rubber pad at the bottom of the first inner box, the rubber pad abuts against the bottom surface of the box frame, effectively filling the gap between the first inner box and the bottom surface of the box frame. This not only reduces the visual sense of emptiness and improves the overall aesthetics of the product, but also makes the drawer box look neater and more integrated.
[0018] Optionally, the first inner box has a receiving cavity, and a limiting block is fixed on the top side of the box frame, with the limiting block located inside the receiving cavity.
[0019] By adopting the above technical solution, when the first inner box is pulled, the limiting block can contact the inner wall of the first inner box, restrict the movement range of the first inner box, prevent it from being pulled out excessively, and the buffering effect of the limiting block can absorb the impact force of the first inner box during the pulling process, reduce the stress on the transmission system, and extend the service life of the transmission system.
[0020] Optionally, guide rails are fixed on both sides of the inner wall of the box frame, which are arranged along the slotting direction of the movable groove. Rollers are fixed on the outer peripheral side walls of the first inner box and the second inner box, and the rollers are slidably connected to the guide rails.
[0021] By adopting the above technical solution, the guide rail is set along the slotting direction of the movable groove and is slidably connected to the rollers on the outer peripheral sidewalls of the first inner box and the second inner box. This can accurately guide the movement direction of the inner box, ensuring that the inner box moves parallel within the movable groove. At the same time, the sliding connection between the guide rail and the inner box reduces the friction between the inner box and the box frame, making the pulling or pushing back of the inner box smoother and improving the transmission efficiency.
[0022] Optionally, a first magnetic block is embedded in the side of the first inner box facing the second inner box, and a second magnetic block is embedded in the side of the second inner box facing the first inner box. The first magnetic block and the second magnetic block abut against each other and attract each other.
[0023] By adopting the above technical solution, when the first inner box and the second inner box are closed and located within the box frame, the magnetic attraction between the first magnetic block and the second magnetic block can fix the first inner box and the second inner box in a specific position, preventing the inner box from sliding or shaking on its own in the movable groove, thus ensuring the stability of the entire drawer box structure.
[0024] In summary, this application has at least the following beneficial effects:
[0025] 1. The first inner box and the second inner box share a single movable slot, enabling the two inner boxes to work together. This significantly reduces structural footprint and increases the usable internal space, making it suitable for scenarios that require efficient space utilization.
[0026] 2. The mechanism of synchronously driving the first inner box and the second inner box in the movable slot via a synchronous belt makes it easier to pull out the first inner box and the second inner box. It enables the simultaneous pulling out of the two inner boxes, allowing users to take out multiple items at once, which significantly improves the efficiency of use, and is especially suitable for scenarios that require quick access to items.

[0033] The following section provides a more detailed description, in conjunction with the accompanying diagrams:
[0034] Example 1
[0035] As attached Figure 1 and attached Figure 2 As shown, a pull-out linked drawer box includes a box frame 1, a first inner box 2, a second inner box 3, and a fixing plate 5.
[0036] The box frame 1 is rectangular in shape, and a through slot 11 is opened inside the box frame 1. The first inner box 2 and the second inner box 3 are both rectangular in shape, and each of the first inner box 2 and the second inner box 3 has a cavity 4 for placing items. The first inner box 2 and the second inner box 3 are relatively parallel and located on the same horizontal plane. The first inner box 2 and the second inner box 3 are both located in the slot 11 of the box frame 1, and the first inner box 2 and the second inner box 3 fit together and abut against each other without leaving any gaps between the first inner box 2 and the second inner box 3, so that the space inside the box frame 1 can be fully utilized, increasing the space for items to be held in the cavity 4 of the first inner box 2 and the second inner box 3.
[0037] The first inner box 2 is fixed with a pull rope 21 on one side outside the box frame 1, which makes it easy to pull out the first inner box 2, simplifying the operation steps and improving the user's experience of pulling the first inner box 2.
[0038] As attached Figure 2 and attached Figure 3 As shown, the fixing plate 5 is L-shaped and includes a fixing surface 51 and a transmission surface 52. One side of the fixing surface 51 is fixedly connected to the side wall of the box frame 1, and the other side of the fixing surface 51 abuts against the side wall of the first inner box 2.
[0039] The transmission surface 52 is located at the bottom of the first inner box 2. The transmission surface 52 is perpendicularly and fixedly connected to the fixed surface 51. The transmission surface 52 is relatively parallel to the bottom surface of the box frame 1. The transmission surface 52 has an inwardly recessed relief groove 521. The transmission surface 52 is also sleeved with a synchronous belt 6 along the groove direction of the movable groove 11. The synchronous belt 6 is made of flexible material and is ring-shaped. The synchronous belt 6 includes a trigger end 61 and a transmission end 62. The trigger end 61 and the transmission end 62 are respectively located in the two relief grooves 521 of the transmission surface 52, and the synchronous belt 6 is slidably connected to the transmission surface 52.
[0040] A connecting plate 7 is fixed on the side of the synchronous belt 6 facing away from the first inner box 2. The upper and lower sides of the connecting plate 7 abut against the bottom surface of the synchronous belt 6 and the box frame 1, respectively. The trigger end 61 is fixedly connected to the bottom of the first inner box 2, and the transmission end 62 is fixedly connected to the connecting plate 7. The end of the connecting plate 7 away from the transmission end 62 is fixedly connected to the bottom of the second inner box 3. The contact between the connecting plate 7 and the synchronous belt 6 ensures its linkage with the first inner box 2. The contact with the bottom surface of the box frame 1 enables the stable movement of the connecting plate 7, ensuring that the second inner box 3 can slide stably.
[0041] Example 2
[0042] This second embodiment is an improvement on the first embodiment. All other structures are the same as those in the first embodiment, and will not be described in detail here.
[0043] As attached Figure 4 and attached Figure 5 As shown, a limiting block 12 is fixed on the top side of the box frame 1. The limiting block 12 is located in the receiving cavity 4 of the first inner box 2. When the first inner box 2 is pulled out to its maximum extent, the limiting block 12 abuts against the inner wall of the first inner box 2, limiting the range of movement of the first inner box 2 and preventing it from being pulled out excessively. The buffering effect of the limiting block 12 can absorb the impact force of the first inner box 2 during the pulling process, reduce the stress on the transmission system, and extend the service life of the transmission system.
[0044] Guide rails 13 are fixed on both sides of the inner wall of the box frame 1, which are arranged along the direction of the movable groove 11. Rollers 8 are fixed on the outer side walls of the first inner box 2 and the second inner box 3, and the first inner box 2 and the second inner box 3 are slidably connected to the guide rails 13 through the rollers 8. The guide rails 13 are arranged along the direction of the movable groove 11 and are slidably connected to the first inner box 2 and the second inner box 3, which can accurately guide the movement direction of the inner box and ensure that the inner box moves parallel within the movable groove 11. At the same time, the sliding connection between the guide rails 13 and the inner box reduces the friction between the inner box and the box frame 1, making the pulling or pushing back of the inner box smoother and improving the transmission efficiency.
[0045] A rubber pad 22 is fixed to the bottom of the side of the first inner box 2 where the pull cord 21 is installed. The rubber pad 22 is made of elastic material and abuts against the bottom surface of the box frame 1. The thickness of the rubber pad 22 gradually increases from the bottom surface of the box frame 1 to the first inner box 2. The rubber pad 22 effectively fills the gap between the first inner box 2 and the bottom surface of the box frame 1, which not only reduces the visual sense of emptiness and improves the overall aesthetics of the product, but also makes the drawer box look cleaner and more integrated.
[0046] A first magnetic block 23 is embedded in the side of the first inner box 2 facing the second inner box 3, and a second magnetic block 31 is embedded in the side of the second inner box 3 facing the first inner box 2. The first magnetic block 23 and the second magnetic block 31 abut against each other and attract each other. The magnetic attraction between the first magnetic block 23 and the second magnetic block 31 can fix the first inner box 2 and the second inner box 3 in a specific position, preventing the inner boxes from sliding or shaking on their own in the movable groove 11, thus ensuring the stability of the entire drawer box structure.
[0047] Working principle:
[0048] When a user needs to place or remove items, they pull the cord 21 on the first inner box 2, causing the first inner box 2 to be pulled backwards. The first inner box 2 will then move the timing belt 6 to slide on the transmission surface 52. The sliding of the timing belt 6 will then drive the connecting plate 7 to move, pushing the second inner box 3 out of the box frame 1 in the opposite direction to the first inner box 2. This allows the first inner box 2 and the second inner box 3 to open simultaneously, enabling the user to remove or place multiple items.
[0049] When it is necessary to close the first inner box 2 and the second inner box 3, push the first inner box 2 toward the movable groove 11. The first inner box 2 will drive the synchronous belt 6 to slide, and then the synchronous belt 6 will synchronously drive the second inner box 3 to push into the movable groove 11. After pushing to a certain extent, the first inner box 2 and the second inner box 3 will come into contact with each other. The first magnetic block 23 and the second magnetic block 31 will attract each other and stick the first inner box 2 and the second inner box 3 together, thereby completing the closure of the first inner box 2 and the second inner box 3 inside the box frame 1.
[0050] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
