Abstract
Description
Technical Field
[0001] This invention relates to a desk that is easy for students to use. It belongs to the field of desk technology, specifically to a desk with adjustable drawers. Background Technology
[0002] The existing student desks have the following prominent problems in actual use: Fixed and non-adjustable height: Traditional school desks have a uniform standard height (e.g., 750mm), but students of different ages have significant height differences (e.g., lower elementary school students are about 120-140cm tall, while upper elementary school students are about 140-160cm tall). A fixed height can easily lead to students sitting with crooked posture (e.g., slouching or shrugging), and long-term use may cause health problems such as myopia and scoliosis.
[0003] Limited storage space in desk drawers: Desk drawers are mostly one-piece structures with a fixed internal height, making it impossible to adjust the space according to the size of items such as books and stationery (e.g., large textbooks need to be stored vertically, and small stationery needs to be placed in layers), resulting in low storage efficiency.
[0004] Insufficient connection stability: The table legs and drawers are mostly connected by welding or single bolts, which are prone to loosening under long-term stress (such as students lying on the table or dragging it), posing a safety hazard; the sides of the drawers lack reinforcement structures and are prone to deformation with frequent opening and closing.
[0005] Inconvenient to hang items: Students' backpacks, water cups, jump ropes and other items are usually placed on the ground or at the corner of the table, which are easily stepped on or tripped over, and spoil the cleanliness of the classroom.
[0006] Therefore, a student desk with adjustable height, flexible drawer space, stable connection, and hanging function needs to be designed to solve the above problems. Utility Model Content
[0007] The technical problem to be solved by this utility model is to overcome the existing defects and provide a desk that is easy for students to use, thereby solving the problems of fixed and non-adjustable height, fixed desk drawer space, insufficient connection stability and lack of suspension structure in current desks.
[0008] To achieve the above objectives, this utility model provides the following technical solution: A desk designed for student use includes table legs, with table drawers fixedly connected to the top of the table legs via connectors. The table drawers consist of a lower drawer and an upper drawer, which are also connected via connectors after adjustment. A desktop is mounted on the top of the upper drawer.
[0009] As a preferred embodiment of this utility model, the table leg includes two side legs, which are connected by a connecting rib, and a support pad is installed at the bottom arc-shaped position of the side legs.
[0010] As a preferred technical solution of this utility model, the connector includes a boss welded to the side leg. The boss is provided with four bosses that are symmetrically distributed on both sides of the top of the side leg. The boss has a screw hole inside, and a bolt is threaded into the screw hole.
[0011] As a preferred embodiment of this utility model, a reinforcing plate is installed on the side of the lower bucket at the position corresponding to the boss, and a connecting hole is provided on the lower bucket at the position corresponding to the screw hole.
[0012] As a preferred embodiment of this utility model, an opening is provided between the two adjacent bosses, and a hook is engaged on the side leg of the opening.
[0013] As a preferred technical solution of this utility model, a second connection hole is provided on the lower bucket at the position corresponding to the first connection hole, and the end of the bolt is disposed inside the second connection hole.
[0014] Compared with the prior art, the beneficial effects of this utility model are: With the vertical sliding of the upper and lower compartments and the selection of multiple sets of connecting holes, the height of the desktop can be adapted to students of different heights (such as 700-900mm continuous adjustment), enabling students to maintain the correct sitting posture of "one fist, one foot, and one inch" (chest one fist away from the table, eyes one foot away from the book, and fingers one inch away from the pen tip), effectively preventing myopia and scoliosis.
[0015] The nested structure of the upper and lower drawers allows for simultaneous adjustment of the internal height of the drawers (e.g., the total height of the drawers increases by 50mm after adjustment), enabling both vertical storage of large textbooks (e.g., A4 size textbooks) and layered placement of stationery (e.g., inserting dividers), thus improving space utilization.
[0016] Four symmetrical bosses are connected by bolts, increasing the contact area between the table legs and the drawer (single bolt load capacity ≥100N); the reinforcing plate of the lower drawer further disperses the stress, avoiding deformation or loosening caused by long-term use, and the structural lifespan is increased by more than 30% compared with traditional school desks.
[0017] The hooks at the side leg openings can support a weight of over 5kg, allowing students to hang their backpacks, water bottles, and other items here to prevent clutter on the ground and reduce the risk of tripping. The hooks are removable via elastic clips for easy cleaning or replacement.
[0018] The rubber pads increase the coefficient of friction between the desk and the ground (μ≥0.6), so the desk is not easy to slide even if students lean on the table. The curved design of the pads fits the ground more closely, avoiding the risk of tipping over caused by single-point force on the desk legs. Attached Figure Description

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-3 This utility model provides a technical solution: A desk designed for easy use by students includes table legs 1, connectors 3, drawers 2, and a desktop 6. The drawer 2 consists of a lower drawer 21 and an upper drawer 22. The lower drawer 21 is fixed to the table legs 1 via connectors 3, and the upper drawer 22 is adjustablely connected to the lower drawer 21 via the same set of connectors 3. The desktop 6 is installed on the top of the upper drawer 22, and its height is adjusted by the vertical movement of the upper drawer 22.
[0022] Core structural design Stability design of table leg 1: The table leg 1 consists of two side legs 11, which are welded together by connecting ribs 12, preferably triangular ribs, to enhance torsional strength. The bottom arc-shaped support pads 13 are made of rubber with a thickness of 5-8mm, which can increase the friction with the ground to prevent slipping, and also buffer the vibration and noise when the table is under stress, while preventing the metal table legs from scratching the ground.
[0023] Adjustable connection of connector 3: The connector 3 is the core adjustment structure, including four bosses 31 symmetrically welded to the top two sides of the side leg 11, two on each side; each boss 31 has a screw hole 32 with M8 thread, 15mm deep, and the screw hole 32 has a threaded bolt 33 with a length of 30mm and a head with anti-slip texture.
[0024] An opening 4 with a width of 20-30mm and a height flush with the protrusion is reserved between two adjacent protrusions 31. The side leg 11 is connected to the hook 5 on the side of the opening 4 by an elastic clip such as a plastic buckle. The hook is made of metal and has a load-bearing capacity of ≥5kg. It is used to hang items such as school bags and water cups.
[0025] Adjustable design of drawer 2: Table drawer 2 has a double-layer nested structure. Both the lower drawer 21 and the upper drawer 22 are rectangular frames made of 0.8mm cold-rolled steel sheet by stamping. The upper drawer 22 can slide vertically along the lower drawer 21. The specific structure is as follows: Lower bucket 21: A reinforcing plate 24 with a thickness of 1.2mm and a width consistent with that of the boss 31 is welded to the side of the lower bucket 21 at the position corresponding to the boss 31 to enhance the connection strength between the lower bucket 21 and the boss 31; A connecting hole 25 with a diameter of 8.5mm is opened on the lower bucket 21 at the position corresponding to the screw hole 32, which is clearance-fitted with the bolt 33 for fixing the lower bucket 21 to the table leg 1.
[0026] Upper bucket 22: Connecting holes 26 are provided on the side, arranged vertically in 3-5 groups with equidistant spacing. Each group has 2 holes with a hole spacing of 50mm and the same diameter as connecting hole 1 25. Bolts 33 are passed through connecting holes 26 and screwed into the screw holes 32 of the boss 31 to fix the upper bucket 22 to the table leg 1. The inner side wall of the upper bucket 22 and the outer side wall of the lower bucket 21 have a clearance fit of 1-2mm on one side to ensure that the upper bucket 22 can slide vertically along the lower bucket 21.
[0027] Desktop Panel 6 Height Adjustment Logic: The desktop panel 6 is fixed to the top of the upper bucket 22 with screws spaced 100-150mm apart to ensure a secure connection. When the height of the desktop panel needs to be adjusted, loosen the bolt 33, slide the upper bucket 22 vertically along the lower bucket 21 to the target position (e.g., select the second set of connecting holes 26), and then tighten the bolt 33 to fix it. This allows the height of the desktop panel 6 to be adjusted from 50-200mm, covering the height needs of elementary to junior high school students.
[0028] Assembly and adjustment steps Step 1: Assemble the table legs and connectors Place the two side legs 11 in parallel and weld them together with the triangular connecting ribs 12. The weld length should be ≥50mm to ensure torsional strength. Four bosses 31 with a height of 20mm are symmetrically welded on both sides of the top of the side leg 11. The bosses are fully welded to the contact surface with the side leg 11. An M8 screw hole 32 with a depth of 15mm is machined in the center of the boss 31. An opening 4 with a size of 25mm × 20mm is cut between adjacent bosses 31, and elastic clips such as plastic buckles are installed on the side of the opening 4 to secure the hook 5.
[0029] Step 2: Table drawer fabrication and installation The lower bucket 21 is made of 0.8mm cold-rolled steel plate stamped into a rectangular frame with dimensions of 500mm long × 400mm wide × 200mm high. A reinforcing plate 24 with dimensions of 80mm long × 20mm wide × 1.2mm thick is welded on the side, and a connecting hole 25 with a diameter of 8.5mm is opened on the reinforcing plate 24. The upper bucket 22 has dimensions of 500mm in length × 400mm in width × 250mm in height. The outer wall of the upper bucket 22 has a gap of 1mm between the outer wall and the inner wall of the lower bucket 21. Three sets of connecting holes 26 are equally spaced in the vertical direction on the side, with two holes in each set. The holes are spaced 50mm apart and have a diameter of 8.5mm. The upper bucket 22 is nested on the outside of the lower bucket 21, so that the second connection hole 26 of the upper bucket 22 is aligned with the first connection hole 25 of the lower bucket 21. The bolt 33 is passed through the connection hole and screwed into the screw hole 32 of the boss 31 to complete the initial fixation of the table bucket 2 and the table leg 1. The second connection hole 26 of the middle group is used by default.
[0030] Step 3: Desktop installation and height adjustment The desktop board 6 is made of 15mm thick MDF with fireproof board on the surface. Its dimensions are 600mm long × 500mm wide. It is fixed to the top of the upper bucket 22 with 4 M6 countersunk screws with a screw spacing of 150mm. When the height needs to be adjusted, such as when the student grows taller, loosen bolt 33, slide the upper bucket 22 upward along the lower bucket 21 to the target connection hole 26 as the top group, and tighten bolt 33 again to increase the height of the desktop board 6 by 50mm, raising the total height from 750mm to 800mm.
[0031] Use Case Examples For elementary school students in the lower grades who are 120-140cm tall: Select the bottom group with connection hole 26, desktop height 700mm, elbows naturally resting on the desktop when the student is sitting upright, eyes about 33cm away from the book, which meets the requirement of one foot.
[0032] For upper elementary school students with a height of 140-160cm: Select the middle group connecting hole 26, the desktop height is 750mm, the student's back is straight, and the chest is about 10cm away from the edge of the table.
[0033] For junior high school students with a height of 160-175cm: Select the top group connection hole 26, and the desktop height 800mm to avoid spinal compression caused by students leaning on the desk.
