[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses an extendable environmental art professional drawing and design table. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 An extendable environmental art professional drawing and design table includes a support 1, a first tabletop 2 on the surface of the support 1, and an extension mechanism 3 on the inner wall of the first tabletop 2.

[0025] The extension mechanism 3 includes a second desktop 301, which is disposed within the cavity of the first desktop 2. A groove 302 is formed in the inner wall of the first desktop 2. A pivot 304 is fixedly connected to the inner wall of the second desktop 301, with both ends of the pivot 304 rotatably connected to the inner wall of the groove 302. The second desktop 301 is rotatably connected to the inner wall of the groove 302 via the pivot 304. An arc-shaped slide rail 303 is fixedly connected to the inner wall of the groove 302. An arc-shaped slider 305 is fixedly connected to one side of the second desktop 301 and slides along the inner wall of the arc-shaped slide rail 303. By setting up the extension mechanism 3, the second desktop 301 can be extended to the side or top of the first desktop 2 by rotation. Users can freely adjust the layout of the drawings according to actual needs, enabling simultaneous viewing of multiple drawings and reducing operational interference and time loss caused by frequent switching of drawings. When the extension function is not needed, the second desktop 301 can be stored inside the first desktop 2, maintaining the compactness of the overall structure, saving space and helping to maintain a clean and orderly working environment.

[0026] Reference Figure 4A handle 4 is fixedly sleeved on the surface of the rotating shaft 304. One side of the handle 4 is fixedly connected to one side of the second desktop 301. By setting the handle 4, the user can more easily apply force and conveniently rotate and adjust the second desktop 301, thus improving convenience.

[0027] Reference Figure 4 The inner wall of the arc-shaped slider 305 is rotatably connected with four balls 6. The surface of the balls 6 contacts the inner wall of the arc-shaped slide rail 303. By setting the balls 6, the friction of the arc-shaped slider 305 when it moves on the arc-shaped slide rail 303 can be reduced, making the arc-shaped slider 305 move more smoothly and avoiding jamming.

[0028] Reference Figure 2 and Figure 5 The inner wall of the first desktop 2 is provided with two locking blocks 5. The locking blocks 5 work together with the second desktop 301. By setting the locking blocks 5, the second desktop 301 can be supported after it is unfolded, ensuring the stability and safety of the second desktop 301 after unfolding, and preventing the second desktop 301 from shaking after unfolding.

[0029] Reference Figure 3 and Figure 5 Two mounting brackets 7 are fixedly connected to one side of the first desktop 2. Two slots 8 are opened on the inner wall of the first desktop 2. The mounting brackets 7 are fixedly connected to the surface of the slots 8. The card block 5 is slidably connected to the inner wall of the slots 8. By setting the mounting brackets 7 and the slots 8, the card block 5 can be limited and supported, ensuring that the card block 5 will not be offset or moved due to external factors.

[0030] Reference Figure 5 One end of each of the two clips 5 is fixedly connected to a connecting rod 9. One end of the connecting rod 9 extends through to the outside of the mounting bracket 7. One end of the connecting rod 9 is fixedly connected to a connecting block 10. By setting the connecting rod 9 and the connecting block 10, the user can easily move the clips 5, easily remove the support of the clips 5 on the second desktop 301, and easily store the second desktop 301.

[0031] Reference Figure 5 Springs 11 are fitted on the surfaces of both connecting rods 9. One end of the spring 11 is fixedly connected to one end of the locking block 5, and the other end of the spring 11 is fixedly connected to the inner wall of the mounting bracket 7. By setting the spring 11, elastic potential energy can be added to the locking block 5 and the connecting rod 9, which can reset the moving locking block 5 and the connecting rod 9, thus ensuring the stability of the locking block 5 and the connecting rod 9.

[0032] Working principle: When the user needs to place multiple drawings, the user moves behind the first desktop 2. The second desktop 301 can be rotated to the side or above the first desktop 2 for easy viewing. The second desktop 301 is rotated out of the groove 302 of the first desktop 2 by manually turning the handle 4. As the second desktop 301 rotates around the pivot 304, the arc-shaped slide rail 303 guides the arc-shaped slider 305, ensuring that the second desktop 301 moves along a preset path. The ball bearing 6 reduces friction and resistance during the movement of the arc-shaped slider 305. When the user needs to rotate the second desktop 301 to the side of the first desktop 2, the handle 4 is turned manually. Pulling the connecting block 10 causes the connecting rod 9 and the locking block 5 to move synchronously. At this time, the locking block 5 will disengage from the slot 8, releasing the restriction on the second desktop 301. As the locking block 5 moves, the spring 11 is compressed, storing elastic potential energy, which provides power support for the subsequent automatic reset of the locking block 5. After disengaging from the slot 8, the locking block 5 removes the restriction on the second desktop 301 in the groove 302, allowing the second desktop 301 to rotate out. When the second desktop 301 is adjusted to the required position, the connecting block 10 is released. Under the restoring force of the spring 11, the locking block 5 returns to the slot 8, completing the support for the unfolded second desktop 301 and ensuring the stability of the unfolded second desktop 301.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
