[0021] The purpose of this invention is to provide a drawing table to solve the problems existing in the prior art, making the drawing process convenient and comfortable, and improving the quality and efficiency of drawing.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1 like Figures 1 to 12 As shown, this embodiment provides a drawing table, a support frame 1, and a desktop assembly. The desktop assembly is mounted on the support frame 1 and includes a drawing panel 2 and a storage panel 3. One side of the drawing panel 2 is hinged to the support frame 1, and the other side is movably connected to the support frame 1, allowing the drawing panel 2 to be tilted relative to the horizontal plane. The storage panel 3 and the drawing panel 2 can be joined together to form the desktop. In this embodiment, by separating the drawing panel 2 and the storage panel 3, the desktop structure of the drawing table is modified to achieve deformation and adjustment, thereby meeting different usage needs and providing a place to place drawing tools. Simultaneously, the drawing panel 2 can be tilted relative to the horizontal plane, allowing the selection of the optimal drawing angle and ensuring comfort during the drawing process.

[0024] As an optional solution, in this embodiment, the support frame 1 includes support legs 4 and a top frame 7. The top frame 7 is fixedly connected to the support legs 4, and a desktop assembly is mounted on the top frame 7. In this embodiment, the sides and rear of the support legs 4 are reinforced by crossbars. In particular, a metal reinforcing plate or reinforcing rod can be connected between the two rear support legs 4. The reinforcing plate or reinforcing rod can be placed close to the ground to avoid obstructing or restricting the feet of the drafter, and can counteract the torsional force generated by the left and right swaying of the table, making the table more stable.

[0025] As an optional solution, in this embodiment, the support leg 4 is a telescopic rod 9. The telescopic rod 9 has several adjustment positions, each capable of extending or retracting at least 1cm, suitable for different users' needs regarding the height of the drawing panel 2. The height of the support leg 4 is at least 40cm, adjustable to accommodate users of different heights, ensuring good drawing comfort. Preferably, brakeable casters 25, 6cm-8cm high, can be installed at the bottom of the support leg 4 as needed, facilitating the movement of the drawing table. In this embodiment, the tops of the two support legs 4 on the same side are connected by a round rod, ensuring synchronous raising and lowering of the support legs 4. The height range of the telescopic rod 9 for the basic version of the drawing table is 74cm-118cm (including the table legs), while the height range for the telescopic rod 9 for the professional version of the drawing table is 65cm-130cm (including the table legs).

[0026] As an optional solution, in this embodiment, the top frame 7 is connected to several support beams 8. Both the top frame 7 and the support beams 8 have several mounting holes 14 arranged symmetrically in mirror image. The mounting holes 14 of the top frame 7 are used to connect the support beams 8. The telescopic rod 9 is an electric push rod, and a lifting controller 27 is connected to the electric push rod. In this embodiment, the lifting controller 27 is preferably a momentary controller, which has two buttons: "raise" and "lower." When the button is pressed, the electric push rod extends or retracts; releasing the button stops it. It can also preset 3-4 height settings to achieve one-button height adjustment. The lifting controller 27 and the power supply are preferably located on the top frame 7. The support beams 8 can be metal square tubes perpendicular to the hinge axis 11 of the drawing panel 2. In this embodiment, the mounting holes 14 of the top frame 7 and the support beam 8 are symmetrical front and back. By installing the accessories on the opposite side, a front-to-back mirror image can be achieved. For example, if the drawing panel 2 is changed from flipping forward to flipping backward, and the storage panel 3 is changed from sliding forward to sliding backward, the entire table can be rotated 180° for installation. This allows the drawing panel 2 and the storage panel 3 to be swapped, and users can adapt to their different left-right usage habits and make their own adjustments.

[0027] As an optional solution, in this embodiment, one side of the bottom surface of the drawing panel 2 is hinged to the top frame 7 of the support frame 1 via at least one hinge, and the middle part is hinged to the top rod of the telescopic rod 9. The outer cylindrical end of the telescopic rod 9 is movably connected to the top frame 7. The telescopic rod 9 is an electric push rod, a pneumatic push rod, or a hydraulic push rod, preferably a gas spring. The telescopic rod 9 is communicatively connected to a controller 28. The controller 28 is equipped with a button for tilting the drawing panel 2, which allows the drawing panel 2 to rotate at an angle of 0°-88°. In this embodiment, the controller 28 is preferably a momentary controller, equipped with three preset positions and left or right turn buttons. The controller 28 is preferably located on the upper left side of the drawing panel 2 for easy operation. When the left or right turn button on the controller 28 is pressed, the telescopic rod 9 extends or retracts, and stops when the button is released, achieving stepless length adjustment, thus enabling arbitrary rotation of the drawing panel 2 within its usable angle range.

[0028] As an optional solution, in this embodiment, the middle part of the drawing panel 2 is hinged to the telescopic rod 9 via a vertical bearing 10 and a hinge shaft 11. This eliminates the play between components, prevents the tabletop angle from not being leveled when the telescopic rod 9 is retracted to its shortest length, or prevents the push rod from not being retracted to its shortest length after the tabletop is leveled, thus avoiding shaking and eliminating noise caused by friction between components. The vertical bearing 10 is connected to a reinforcing plate 13 by bolts 12. The reinforcing plate 13 is a metal plate to prevent direct contact with the wooden tabletop and the resulting slippage. Specifically, the hinge structure between the vertical bearing 10 and the telescopic rod 9 is as follows: a pair of bearings are provided on a U-shaped vertical bearing seat, and a pair of pin holes are provided at the outer end of the inner ring of each bearing. The two ends of the hinge shaft 11 are respectively connected to the pair of pin holes by pins. The top of the telescopic rod 9 is connected by bolts 12 (studs). There is a screw, and a through hole or threaded hole is provided in the middle of the hinge shaft 11. The screw passes through the through hole or threaded hole, and two locking nuts 16 are threadedly connected to the screw. The two locking nuts 16 are located on both sides of the hinge shaft 11. The two locking nuts 16 clamp the hinge shaft 11 onto the screw. The extension length of the end of the screw is less than the distance between the hinge shaft 11 and the base plate of the vertical bearing seat to avoid motion interference. The radius of the telescopic rod 9 is not greater than the radius of the vertical bearing seat 10. At this time, there is no wobbling or play between the entire set of accessories. This is different from the 0.5mm-1mm gap between the pin 21 and the pin hole in traditional hinge parts. Since both ends of the telescopic rod 9 are hinged, the play of the telescopic rod 9 will be magnified many times, which will eventually cause the table to wobble by 5-10mm. To prevent the table from wobbling, a buffer pad can also be set on the top frame 7. A pair of vertical plates are connected to the support beam 8 connected to the top frame 7. Each vertical plate is equipped with a vertical bearing 10. The two vertical bearings 10 are arranged coaxially. A connecting rod 15 passes through the two vertical bearings 10 and the outer cylinder ends of the two telescopic rods 9. The two ends of the connecting rod 15 are respectively provided with a thread. The connecting rod 15 is fixedly connected to the inner ring of the bearing of the vertical bearing 10 by bolts 12 or pins. The outer cylinder ends of the telescopic rods 9 are respectively fixedly connected to the ends of the connecting rod 15 by a locking nut 16 to ensure the synchronous movement of the two telescopic rods 9.

[0029] As an optional solution, in this embodiment, the hinge end of the drawing panel 2 is provided with a storage shelf 17. The storage shelf 17 is U-shaped and its width is greater than the thickness of the drawing panel 2. One end of the storage shelf 17 is connected to the bottom surface of the drawing panel 2 by at least one hinge, and the other end is supported by the edge of the drawing panel 2. The hinge is a limiting hinge, which can be rotated to a position of 0°, 90°, and 150°. In this embodiment, the storage shelf 17 can be folded up or unfolded to hold books, sketchbooks, and art supplies, which is an important function for artists. By modifying the limiting stop of the limiting hinge, a limiting position of 0°-90°-150° is achieved, and the storage shelf 17 will not collide with other parts when rotated 150°. Specifically, the limiting hinge includes a first hinge piece 18, a limiting tooth piece 20, a pin 21, and a second hinge piece 19. The first hinge piece 18 is connected to the storage shelf 17 or the drawing panel 2 by bolts 12, and the second hinge piece 19 is connected to the drawing panel 2 or the storage shelf 17 by bolts 12. The central hinge ears of the first hinge piece 18 and the second hinge piece 19 are connected sequentially by the pin 21. The limiting tooth piece 20 is sleeved on the pin 21 and fixedly disposed between the two hinge ears of the second hinge piece 19. A sleeve is provided in the middle of the first hinge piece 18. Inside the cylinder, a steel ball 22, a spring 23, and a limiting stud 24 are arranged in sequence. The sleeve and the limiting stud 24 are connected by threads. The steel ball 22 always abuts against the side wall of the limiting tooth 20. The limiting tooth 20 is provided with three sliding grooves and one stop groove. The three sliding grooves are all arc-shaped grooves and correspond to the limiting of the second hinge piece 19 rotation from 0° to 90° to 150° respectively. The stop groove is a right-angle groove. The right-angle groove is engaged with the right-angle edge of the second hinge piece 19, and the groove wall of the right-angle groove is provided with a protrusion to facilitate engagement with the second hinge piece 19 and fix the limiting tooth 20. In this embodiment, the first hinge piece 18, the limiting tooth piece 20 and the drawing panel 2 are fixed relative to each other. When the placement stop bar 17 is moved, the second hinge piece 19 can be rotated around the pin 21. When the steel ball 22 in the sleeve of the second hinge piece 19 is stuck in the sliding groove, the placement stop bar 17 can be limited by 0°-90°-150°.

[0030] As an optional solution, in this embodiment, the storage panel 3 includes a fixed panel 5 and a movable panel 6. The fixed panel 5, the movable panel 6, and the drawing panel 2 can be spliced ​​together to form a rectangular tabletop. The bottom surface of the fixed panel 5 is connected to the top frame 7 or support beam 8 of the support frame 1 by bolts 12. The fixed panel 5 is located on top of the drawing panel 2, and the movable panel 6 is located on the left or right side of the drawing panel 2. The movable panel 6 is slidably mounted on the support frame 1 via a slide rail 29. The support frame 1 is connected to the movable panel 6 via a pair of double-axis linear guide rails, and the movable panel 6 can move along the direction perpendicular to the hinge axis 11 of the drawing panel 2.

[0031] As an optional solution, in this embodiment, the support beam 8 at the top of the support frame 1 is provided with mounting holes 14 for connecting the drawer cabinet assembly. The drawer cabinet assembly includes several drawer cabinets 26, each including drawers and open cabinets. The drawers are slidably fitted inside the open cabinets.
