Description

Technical Field

[0001] This utility model relates to the technical field of stackable and expandable bamboo shelf structures, specifically a stackable and expandable bamboo shelf structure. Background Technology

[0002] Bamboo shelving structures refer to frame-like storage or display devices with layered support surfaces, assembled using bamboo as the main raw material through specific methods (such as mortise and tenon joints, connectors, and binding). Due to its rapid growth, high strength, beautiful texture, and strong sustainability, bamboo is widely used in various scenarios such as support and display to meet the needs of item classification and storage, efficient space utilization, and visual presentation.

[0003] However, traditional bamboo shelving structures have shortcomings in practical applications: First, their design is mostly a fixed single structure with a fixed height and number of layers, making it impossible to disassemble and reassemble, and difficult to flexibly adjust or expand according to actual space changes or increased storage needs; second, traditional bamboo shelves cannot be moved easily and have a certain degree of instability. When they collide or are moved, they may tilt during transport, causing the stored items to fall. These inherent limitations pose challenges to the flexibility, space utilization, structural stability, and adaptability of traditional bamboo shelves. Utility Model Content

[0004] The purpose of this invention is to provide a stackable and expandable bamboo shelf structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stackable and expandable bamboo shelf structure, including a base frame and a support column fixedly connected to the upper side of the base frame, a quick stacking mechanism is provided on the inner side of the support column, and a movable and stabilizing mechanism is provided on the lower side of the base frame;

[0006] The rapid stacking mechanism includes a metal frame slidably connected between pillars. Multiple bamboo strips are fixedly connected to the inner side of the metal frame. Multiple sliding grooves are formed inside the lower side of the metal frame, located on the side of the metal frame closest to adjacent pillars. A centering rod is slidably connected inside each groove. A slider is threadedly connected to the opposite end of each centering rod, and the sliders are slidably connected inside the groove.

A metal sliding plate is fixedly connected to the upper surface of each stabilizing block, and the lower surface of each metal sliding plate has a clearance fit with the upper surface of the metal frame. A post is fixedly connected to the opposite end of each slider, and the post is slidably connected inside adjacent pillars. Multiple magnetic blocks are fixedly connected to the upper surface of the metal frame, and the magnetic blocks attract the adjacent metal sliding plates.

[0007] Preferably, the support column is configured as a metal tubular structure or a plastic rod structure, and multiple slots are provided on each adjacent side of the support column, with the slots evenly distributed on the support column.

[0008] Preferably, the corners of the metal frame are provided with slots that fit with the outer wall of the support column.

[0009] Preferably, each of the inserts has a downward-facing oblique opening at one end.

[0010] Preferably, the movable and stabilizing mechanism includes a base leg, which is fixedly connected to the lower surface of the base frame.

[0013] Compared with the prior art, this utility model provides a stackable and expandable bamboo shelf structure, which has the following beneficial effects:

[0014] 1. The quick stacking mechanism is used for quick stacking or disassembly. This mechanism opens multiple slots inside the support column, and uses springs and inserts as snap-fit ​​components to allow the metal frame to be quickly connected to the support column in the form of mortise and tenon joints. With the help of multiple sets of centering rods, stabilizing blocks, metal slide plates and inserts, the pressure is distributed in multiple areas. At the same time, the magnetic blocks and metal slide plates can be freely interchanged, so that the device can be flexibly and stably assembled and disassembled.

[0015] 2. The easy-to-move and stabilize mechanism is used to quickly adjust the state of the bamboo shelf and provide stable support. This mechanism uses multiple sets of adjustable casters as a switchable support method. The support plate of this mechanism serves as a fixed-point support structure. With the multiple sets of casters, more support points are provided, making the bamboo shelf less likely to tip over. When it is necessary to move the bamboo shelf, the position of the casters can be lowered for quick movement, so that the device can be moved easily and kept stable when placed.

On the side, stabilizing blocks 307 are fixedly connected to the upper surface of sliders 305. Stabilizing blocks 307 are slidably connected inside the metal frame 301. Metal slide plates 308 are fixedly connected to the upper surface of stabilizing blocks 307. The lower surface of metal slide plates 308 is clearance-fitted with the upper surface of the metal frame 301. Inserted posts 309 are fixedly connected to the opposite ends of sliders 305. Inserted posts 309 are slidably connected inside the adjacent support columns 2. Multiple magnetic blocks 310 are fixedly connected to the upper surface of the metal frame 301. Magnetic blocks 310 attract each other to the adjacent metal slide plates 308. The metal frame 301 can be assembled by welding. The support columns 2 need to be stably installed and can be connected by a metal base frame or a rigid plastic plate without significant loosening. Magnetic blocks 310 are used to limit the insertion of posts 309 when the user changes floors.

[0028] Furthermore, the support column 2 is configured as a metal tubular structure or a plastic rod structure, and multiple slots are opened on the adjacent side of the support column 2, with the slots evenly distributed on the support column 2.

[0029] Furthermore, slots are provided at the corners of the metal frame 301 to fit with the outer wall of the support column 2.

[0030] Furthermore, each of the opposite ends of the insert post 309 has a downward-facing oblique opening.

[0031] Example 2:

[0032] This mechanism is used for easy movement and stable support of bamboo frames. Its switchable support methods enhance the flexibility and stability of the bamboo frames. Please refer to [link / reference needed]. Figure 1-5Furthermore, in conjunction with Embodiment 1, the movable and stabilizing mechanism 4 includes a base leg 401, which is fixedly connected to the lower surface of the base frame 1. Multiple sliding openings 402 are provided on the outer wall of the base leg 401. Adjusting nuts 403 are threadedly connected to the outer wall of each base leg 401. Support plates 404 are fixedly connected to the lower ends of each base leg 401. Connecting seats 405 are rotatably connected to the lower side of each adjusting nut 403. Limiting strips 406 are fixedly connected to the inner wall of each connecting seat 405. Limiting strips 406 are slidably connected inside adjacent sliding openings 402. Multiple support rods 407 are fixedly connected to the outer side of each connecting seat 405. Multiple support rods 407 are evenly distributed on the outer side of adjacent connecting seats 405.

[0033] Furthermore, the limiting strip 406 has a square cross-section.

[0034] Furthermore, the casters 409 are all located on the outer side of the adjacent supports.

[0035] In actual operation, when this device is in use, due to the numerous insertion holes on the inner side of the support column 2, both the metal slide plate 308 and the magnetic block 310 are in an attractive state. When stacking, the user can place the metal frame 301 inside the support column 2 and press the metal frame 301. Near the appropriate position, the user can push the metal slide plate 308 to disengage it from the magnetic block 310. After the user continues to press down, the spring 306 pushes the insertion post 309 to engage with the insertion hole, thereby locking the metal frame 301. When changing layers or disassembling, the user can use the magnetic block 310 to limit the position of the metal slide plate 308, making it convenient for the user to change the position of the metal frame 301. When the user changes the position of the bamboo frame, the user can rotate the adjusting nut 403. Since the universal wheel 409 serves as an auxiliary support, the user can rotate each adjusting nut 403 along with it. The adjusting nut 403 drives the connecting seat 405 and the bottom leg 401 to move, which can detach the support plate 404 from the ground. Then the user can push the bamboo frame to move.
