Description

Technical Field

[0001] This utility model relates to the field of desk technology, and in particular to a foldable, layered desk for storage. Background Technology

[0002] As the core carrier of students' learning life, the desk serves the basic function of placing books, stationery, electronic devices and other learning supplies, providing stable flat support for learning activities such as writing, reading and classroom operations. At the same time, the desk also acts as a collaborative platform to facilitate the exchange and dissemination of knowledge. It is an indispensable and important tool to ensure students' efficient learning and healthy growth.

[0003] Traditional school desks typically employ a fixed structure design, with the desktop and legs connected in a fixed manner. This results in a large overall size and difficulty in folding. In terms of classroom space planning, when a classroom needs temporary renovations, such as for hosting events or storing the desks during winter and summer vacations, the fixed structure prevents flexible adjustments to space usage, making transportation and storage extremely inconvenient. Furthermore, it occupies a significant amount of storage space. Therefore, a foldable, layered, and storage-friendly desk has been designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foldable, layered, and storage-friendly desk.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A foldable, layered, and foldable desk includes a desktop. Connecting rods are fixedly connected to the four corners of the bottom of the desktop, with the connecting rods on both sides having different lengths. Two connecting rods on the same side are rotatably connected to the same U-shaped support leg near the center of the desktop. The two U-shaped support legs have different heights, and the sum of the heights of the connecting rods and the U-shaped support legs on both sides is equal. T-slots are formed on the inner top of each of the two U-shaped support legs. A serrated groove is formed on one side of each T-slot. A limiting mechanism is provided in each T-slot. The limiting mechanism includes an L-shaped block slidably connected in the T-slot. A U-shaped plate is fixedly connected to the bottom outer side of the L-shaped block. A square rod is slidably fitted in the middle of the U-shaped plate. A square hole adapted to the square rod is formed in the middle of the U-shaped plate. The square rod also slidably passes through the L-shaped block. A square hole adapted to the square rod is formed at the bottom of the L-shaped block. An inclined surface is formed at the end of the square rod near the serrated groove, and the inclined surface is adapted to the serrated groove.

[0006] Preferably, the limiting mechanism further includes a handle fixedly connected to the outside of the square rod. A fixing block is fixedly sleeved on the square rod near the L-shaped block and the U-shaped plate. A spring is sleeved on the square rod between the fixing block and the U-shaped plate. The spring ensures that the square rod tightly presses against the inclined tooth groove, preventing the L-shaped block from falling after it rises.

[0007] Preferably, each of the connecting rods has a socket at its bottom, and the socket is adapted to the L-shaped block. The cooperation between the socket and the L-shaped block ensures that the U-shaped support leg is in a stable state after it is vertical.

[0008] Preferably, a shelf is rotatably connected to one side of the top of the desktop, and a threaded rod is fixedly connected to the bottom of the shelf near the edge of the desktop, and a locking bolt is screwed onto the threaded rod. The locking bolt makes it easy to lock and loosen.

[0009] Preferably, a strip-shaped locking hole is provided at the edge of the desktop near the threaded rod, and the strip-shaped locking hole is adapted to the threaded rod. Through the cooperation of the threaded rod, the locking bolt and the strip-shaped locking hole, the shelf is in a stable state after being upright and will not tip over.

[0010] Preferably, a drawer is fixedly connected to the bottom of the desktop.

[0011] The beneficial effects of this utility model are as follows: 1. By employing a technical means involving four connecting rods, two U-shaped support legs, and a limiting mechanism, when the L-shaped block is inserted upwards into the corresponding socket, the two U-shaped support legs can be in a vertical state, allowing the desk to be used stably. When folding is required, the limiting mechanism moves the L-shaped block downwards, thus enabling the U-shaped support legs to fold. At the same time, the different heights of the connecting rods on both sides ensure that the two U-shaped support legs do not obstruct each other after folding. This effectively solves the problem of desks being inconvenient to fold and taking up a lot of space mentioned in the background technology. As a result, the U-shaped support legs can be folded flexibly, facilitating quick storage of desks during classroom relocation, site renovation, or holiday storage, significantly improving space utilization and reducing warehousing and transportation space costs.

[0012] 2. The design incorporates a shelf, threaded rod, and locking bolts, allowing for easy placement of study materials at the front of the desktop, thus improving storage capacity. It is also easy to fold, making it highly practical. Attached Figure Description

[0015] 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.

[0016] Reference Figures 1-6 A foldable, layered, and foldable desk includes a desktop 1. Connecting rods 4 are fixedly connected to the four corners of the bottom of the desktop 1. The lengths of the connecting rods 4 on both sides are different. Two connecting rods 4 on the same side are rotatably connected to the same U-shaped support leg 5 near the center of the desktop 1. The heights of the two U-shaped support legs 5 are different, and the sum of the heights of the connecting rods 4 and the U-shaped support legs 5 on both sides is equal. T-slots 501 are formed on the inner side of the top of each U-shaped support leg 5. A beveled toothed groove 502 is formed on one side of each T-slot 501. Each T-slot 501 contains a... The limiting mechanism 6 includes an L-shaped block 601 slidably connected in a T-slot 501. A U-shaped plate 604 is fixedly connected to the bottom outer side of the L-shaped block 601. A square rod 602 is slidably sleeved in the middle of the U-shaped plate 604. A square hole adapted to the square rod 602 is opened in the middle of the U-shaped plate 604. The square rod 602 also slides through the L-shaped block 601. A square hole adapted to the square rod 602 is opened at the bottom of the L-shaped block 601. An inclined surface is opened at one end of the square rod 602 near the inclined tooth groove 502, and the inclined surface is adapted to the inclined tooth groove 502.

[0017] In this utility model, the limiting mechanism 6 also includes a handle 603 fixedly connected to the outside of the square rod 602. A fixing block 605 is fixedly sleeved on the square rod 602 near the L-shaped block 601 and the U-shaped plate 604. A spring 606 is sleeved on the square rod 602 between the fixing block 605 and the U-shaped plate 604. The setting of the spring 606 makes the square rod 602 tightly press the oblique tooth groove 502, so that the L-shaped block 601 will not descend in its natural state.

[0018] In this utility model, each connecting rod 4 has an insertion hole 401 at its bottom, and the insertion hole 401 is adapted to the L-shaped block 601. By inserting the L-shaped block 601 into the insertion hole 401, the U-shaped support leg 5 is very stable with the connecting rod 4 when it is vertical, so that the desk can be used normally.

[0019] In this utility model, a shelf 3 is rotatably connected to one side of the top of the desktop 1, and a threaded rod 301 is fixedly connected to the bottom of the shelf 3 near the edge of the desktop 1, and a locking bolt 302 is screwed onto the threaded rod 301.

[0020] In this utility model, a strip-shaped locking hole 101 is provided at the edge of the desktop 1 near the threaded rod 301, and the strip-shaped locking hole 101 is adapted to the threaded rod 301. By setting the threaded rod 301 locking bolt 302 and the strip-shaped locking hole 101, the shelf 3 can be used stably after being upright, and can hold some stationery, etc., without tipping over.

[0021] In this utility model, a drawer 2 is fixedly connected to the bottom of the desktop 1. The drawer 2 allows the user to place books or school bags and other items.

[0022] Working principle: When using this desk, the shelf 3 is upright, so that the threaded rod 301 is engaged in the strip-shaped locking hole 101, and the locking bolt 302 is screwed onto the threaded rod 301, so that the locking bolt 302 presses the desktop 1 firmly, allowing the shelf 3 to be used normally and not tip over. Four L-shaped blocks 601 are inserted into the insertion holes 401, ensuring that the U-shaped support legs 5 on both sides are vertical and do not wobble, making the desk stable. When the desk needs to be moved or folded for storage, the locking bolt 302 is rotated to engage the shelf 3 with the strip-shaped locking hole 101. The separation at one point allows the shelf 3 to be folded onto the top of the desktop 1. By pulling the four handles 603, the bevel of the square rod 602 separates from the beveled groove 502. At this time, the fixing block 605 will compress the spring 606, and the L-shaped block 601 can be pulled down, so that the top of the L-shaped block 601 is away from the socket 401. This allows both U-shaped support legs 5 to fold the bottom middle of the desktop 1. At the same time, due to the different heights of the connecting rods 4 on both sides, both U-shaped support legs 5 can be folded at ninety degrees and folded into the bottom of the drawer 2, so that the size of the desk is minimized and does not take up a lot of space.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
