Description

Technical Field

[0001] This utility model belongs to the field of bookcase installation technology, specifically, it relates to a metal frame bookcase that can be quickly disassembled and assembled. Background Technology

[0002] Bookshelves and bookcases are indispensable storage furniture in everyday home and office settings, mainly used to store books, documents, and various items. Their materials include wood, metal, and plastic, and their structural forms have gradually evolved from fixed to modular designs. As users' demands for flexibility in their living spaces increase, easily detachable bookcases are becoming increasingly popular; however, traditional metal-framed bookcases still have significant limitations in their structural design.

[0003] Traditional metal-framed bookcases mostly use bolts and nuts for fastening, requiring tools like wrenches for assembly and disassembly. This process is complex, time-consuming, and labor-intensive, making it inconvenient for the average user. Furthermore, bolted connections involve tedious installation steps, requiring each bolt to be individually aligned and tightened. Misalignment can lead to installation difficulties, and repeated disassembly and reassembly can decrease the precision of the bolt and nut fit, affecting the bookcase's stability. Especially when frequent relocation or changing placement is necessary, the process involves laborious disassembly of numerous connectors and increases the risk of losing parts. This cumbersome operation causes significant inconvenience for users and fails to meet the modern demand for convenient furniture. To address the aforementioned issues, this application proposes a metal frame bookcase that can be quickly disassembled and assembled. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a metal frame bookcase that can be quickly disassembled and assembled, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A metal frame bookcase that can be quickly disassembled and assembled includes a base plate, with a positioning post fixedly connected to the top of the base plate; an installation structure is provided on the top of the base plate; a enclosure structure is provided on the top of the base plate; the installation structure includes a column inserted into the top of the base plate via the positioning post, a connecting rod rotatably connected to the top of the column, a knob fixedly connected to the top of the connecting rod, a square column fixedly connected to the bottom of the connecting rod, a compression spring fixedly connected to the inner side wall of the column, a movable plate fixedly connected to the end of the compression spring away from the inner side wall of the column, a limiting post fixedly connected to the outer wall of the movable plate near the compression spring, a through hole through the outer side wall of the column, the outer side wall of the limiting post fitting with the inner side wall of the through hole, and a chamfered corner provided at the edge of the outer side wall of the square column.

[0006] Preferably, the outer wall of the column is provided with a slot, the cross-section of which is trapezoidal. By providing the slot, it is easy to quickly install and disassemble the bookcase.

[0007] Preferably, a rubber pad is attached to the outer wall of the square column at the corner. By setting the rubber pad, the friction between the outer wall of the square column at the corner and the moving plate can be increased.

[0008] Preferably, the enclosure structure includes a baffle that is snapped onto the outside of the column. A locking block is fixedly connected to one end of the baffle near the column. By setting the locking block, the position of the baffle can be restricted through the locking groove to prevent the baffle from shaking during use.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figure 1-5 A quick-assembly and disassembly metal frame bookcase includes a base plate 1, which serves as the basic support component of the entire bookcase and has good load-bearing capacity. Positioning posts 2 are fixedly connected to the top of the base plate 1. Multiple positioning posts 2 are evenly distributed along the edges of the base plate 1, primarily serving for positioning and initial fixation. An installation structure 3 is provided on the top of the base plate 1. Upright posts 301 are inserted into the top of the base plate 1 via the positioning posts 2, with their number and position corresponding to the positioning posts 2. The positioning posts 2 mate with corresponding holes at the bottom of the upright posts 301, enabling quick assembly of the uprights. The initial positioning of column 301 on base plate 1 prevents offset during installation. A connecting rod 302 is rotatably connected to the top of column 301, and a knob 304 is fixedly connected to the top of connecting rod 302. Rotating the knob 304 rotates the connecting rod 302. A square column 303 is fixedly connected to the bottom of connecting rod 302, rotating with the connecting rod 302. A compression spring 306 is fixedly connected to the inner wall of column 301. In its natural state, compression spring 306 has a certain elastic tension. Compression spring 306 is located away from the column. A movable plate 305 is fixedly connected to one end of the inner wall of the column 301. In the initial state, the movable plate 305 is away from the inner wall of the column 301 under the action of the compression spring 306. A limiting post 307 is fixedly connected to the outer wall of the movable plate 305 near the compression spring 306. A through hole 308 is provided through the outer wall of the column 301. The outer wall of the limiting post 307 fits with the inner wall of the through hole 308, so that the limiting post 307 can move telescopically within the through hole 308. A truncated angle 310 is provided at the corner of the outer wall of the square column 303. When the knob 304 is rotated, the square column 303 moves to move forward. When the column 303 rotates, the side and the corner 310 of the square column 303 will alternately contact the moving plate 305. When the corner 310 of the square column 303 contacts the moving plate 305, it will push the moving plate 305 to move closer to the inner wall of the column 301, thereby causing the limiting column 307 to retract into the through hole 308 and extend to the outside of the column 301. When the side of the square column 303 contacts the moving plate 305, the moving plate 305 moves away from the inner wall of the column 301 under the action of the compression spring 306, causing the limiting column 307 to retract into the inside of the column 301.

[0015] Reference Figure 2 , Figure 3 and Figure 4The outer wall of the column 301 is provided with a slot 309. The cross section of the slot 309 is trapezoidal. This shape design makes it easy to engage with other components, while also ensuring the stability of the connection, and facilitating the quick installation and disassembly of the bookcase.

[0016] Reference Figure 5 A rubber pad is attached to the outer wall of the square column 303 at the truncated angle 310. The rubber pad increases the friction between the outer wall of the square column 303 at the truncated angle 310 and the moving plate 305, making the contact between the square column 303 and the moving plate 305 more stable during rotation and preventing slippage.

[0017] Reference Figure 2 and Figure 3 The top of the base plate 1 is also provided with a barrier structure 4, which is used to block the items inside the bookcase and prevent them from falling. The barrier structure 4 includes a baffle 401 that is snapped onto the outside of the column 301. The baffle 401 is made of metal and has a certain strength. A locking block 402 is fixedly connected to one end of the baffle 401 near the column 301. The locking block 402 cooperates with the slot 309, and the outer side wall of the baffle 401 fits into the inner side wall of the slot 309. By setting the locking block 402, the position of the baffle 401 can be restricted by the slot 309 to prevent the baffle 401 from shaking during use.

[0018] Reference Figure 2 and Figure 3 The outer wall of the card block 402 near the column 301 has a positioning hole 403. The inner wall of the positioning hole 403 fits with the outer wall of the limiting column 307. When the limiting column 307 extends out of the through hole 308, it will be inserted into the positioning hole 403, thereby fixing the baffle 401 and further ensuring the stability of the connection between the enclosure structure 4 and the installation structure 3.

[0019] Working principle: During assembly, the upright column 301 is first installed onto the base plate 1 via the positioning post 2, completing the initial fixation of the installation structure 3. Next, the locking block 402 on the baffle 401 is inserted into the slot 309 of the upright column 301. Then, the knob 304 is rotated so that the truncated angle 310 of the square column 303 contacts the moving plate 305. At this time, the limiting post 307 extends out from the through hole 308 under the action of the compression spring 306, allowing the limiting post 307 to be inserted into the positioning hole 403, thus fixing the enclosure structure 4 to the installation structure 3. For disassembly, simply rotate the knob 304 in the opposite direction so that the side of the square column 303 contacts the moving plate 305, pushing the moving plate 305 to move, thereby causing the limiting post 307 to retract into the through hole 308, releasing the fixation of the baffle 401. Then, the locking block 402 is removed from the slot 309, and finally, the upright column 301 is pulled out of the base plate 1. The disassembly process is equally convenient and efficient.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
