[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figure 1-9 This invention provides a technical solution: an angle-adjustable architectural design drawing stand. This invention addresses the technical problems mentioned in the background art by making corresponding improvements. It includes a frame 1, a drawing board 2 on one side of the frame 1, a storage box 3 fixedly installed on the drawing board 2 by a storage mechanism 8, a receiving mechanism 6 on one side of one of the storage boxes 3 of the drawing board 2, a collecting mechanism 4 on one side of the drawing board 2, one side of the drawing board 2 rotating on the frame 1, and a semi-ring with an adjustment hole on one side of the drawing board 2. The semi-ring is connected to the corresponding adjustment hole by a positioning bolt, which can realize the angle adjustment of the drawing board 2. This is a known and relatively mature existing technology product, and will not be described in detail here.

[0033] The storage mechanism 8 includes an inner cavity 801 and a slot 807. The slots 807 are symmetrically located on both sides of the drawing board 2. The storage box 3 is inserted into the inner side of the slot 807. The inner cavity 801 is located inside the drawing board 2. Mounting plates 803 are symmetrically slidably connected to the inner side of the inner cavity 801. A mounting rod 802 is fixedly mounted on one side of the mounting plate 803. The other end of the mounting rod 802 extends into the inner side of the slot 807 and is fixedly mounted to the storage box 3. Slider blocks 804 are fixedly mounted on opposite sides of the two mounting plates 803. An movable rod 806 is slidably connected to the inner side, and a linkage rod 805 is rotatably connected between the movable rod 806 and the slider 804. An operating mechanism 5 is provided on one side of the movable rod 806. The box slots 807 are symmetrically distributed on both sides of the drawing board 2, making it convenient for users to take out drawing tools. The storage box 3 for storing pens is also equipped with a tube clamp. Since the tube clamp can fix the cylindrical pens, it prevents the pens from falling out when the drawing board 2 is tilted. One end of the linkage rod 805 rotates on the slider 804, and the other end rotates on the movable rod 806.

[0034] See Figure 3 The inner side of the inner cavity 801 is provided with a guide groove 10. The end of the mounting plate 803 is slidably connected to the inner side of the guide groove 10. The inner side of the inner cavity 801 is fixedly installed with a first guide rail 9. The slider 804 and the first guide rail 9 are slidably connected. The inner side of the inner cavity 801 is fixedly installed with a second guide rail 12. The movable rod 806 and the second guide rail 12 are slidably connected. A baffle 11 is provided on one side of the second guide rail 12. Through the guide groove 10 in the inner cavity 801, the two mounting plates 803 can slide synchronously in the inner cavity 801. Through the first guide rail 9 in the inner cavity 801, the slider 804 can slide horizontally in the inner cavity 801. Through the second guide rail 12 in the inner cavity 801, the movable rod 806 can slide in a limited position in the inner cavity 801. At the same time, the baffle 11 on one side of the second guide rail 12 can further limit the movement of the movable rod 806.

[0035] The specific implementation method of this embodiment is as follows: During use, by pushing the movable rod 806 to slide to the limit position at the baffle 11, the movable rod 806 drives the slider 804 to slide through the linkage rod 805. The two sliders 804 slide away from each other, pushing the mounting plate 803 to move. The mounting plate 803 drives the storage box 3 to unfold from the box slot 807 simultaneously through the mounting rod 802. Conversely, by pulling back the movable rod 806, the movable rod 806 drives the sliders 804 to move closer to each other through the linkage rod 805. The sliders 804 drive the storage box 3 back into the box slot 807 through the mounting rod 802 on the mounting plate 803.

[0036] Example 2

[0037] Please see Figures 4-7This invention provides a technical solution: an angle-adjustable architectural design drawing stand. This invention addresses the technical problems mentioned in the background art by making corresponding improvements. The operating mechanism 5 includes a through hole 501, which is opened on one side of the inner wall of the inner cavity 801. A fixed rod 503 is fixedly installed on the inner side of the through hole 501. A first limiting hole 504 and a second limiting hole 505 are respectively opened on the inner side of the fixed rod 503. A push-pull rod 502 is fixedly installed on one side of the movable rod 806. One end of the push-pull rod 502 slides through the through hole 501. The push-pull rod 502 and the fixed rod 503 are slidably connected. The push-pull rod 502 is inserted through a limiting mechanism 7 and a second limiting hole 505. One end of the fixed rod 503 is fixed in the through hole 501 by a screw, while one end of the push-pull rod 502 is connected to the movable rod 806 and slides at the upper limit of the fixed rod 503. The push-pull rod 502 is also provided with an anti-slip groove to facilitate anti-slip when the user holds the end of the push-pull rod 502 to push or pull.

[0038] The limiting mechanism 7 includes a mounting cavity 701, which is located inside the push-pull rod 502. A movable plate 702 is slidably connected to the inner side of the mounting cavity 701. A limiting rod 704 is fixedly installed inside the movable plate 702. One end of the limiting rod 704 is inserted into a second limiting hole 505, and a limiting head 705 is fixedly installed at the other end of the limiting rod 704. A spring 703 is sleeved on the outer side of the limiting rod 704. One end of the spring 703 is fixedly installed to the movable plate 702, and the other end of the spring 703... The push-pull rod 502 is fixedly installed on the inner wall of the mounting cavity 701. A pressing rod 706 is rotatably connected to the outer side of the push-pull rod 502. One end of the pressing rod 706 extends between the limiting head 705 and the push-pull rod 502. One end of the pressing rod 706 is provided with a U-groove. The U-groove is located at the end of the limiting rod 704 near the limiting head 705. This allows the user to easily unlock the push-pull rod 502 by squeezing the raised end of the pressing rod 706. After unlocking, the movable rod 806 can be pushed and pulled by the push-pull rod 502.

[0039] See Figures 4-7A positioning block 19 is fixedly connected to the outer side of the fixed rod 503. A positioning groove 16 is provided on one side of the push-pull rod 502. The positioning block 19 and the positioning groove 16 are slidably connected. A sliding groove 15 is provided on the inner side of the mounting cavity 701. The movable plate 702 and the sliding groove 15 are slidably connected. One side of the push-pull rod 502 is fixedly installed on the support 18. The pressing rod 706 is rotatably connected to the inner side of the support 18. A pad 17 is fixedly installed on the side of the push-pull rod 502 near the support 18. The positioning block 19 on the fixed rod 503 is used to connect the positioning block 19 to the positioning groove 16. 9. The push-pull rod 502 with positioning groove 16 can slide on the fixed rod 503. The movable plate 702 can move stably in the mounting cavity 701 through the shift groove 15 in the mounting cavity 701. The support 18 on the push-pull rod 502 can make the pressing rod 706 rotate on the push-pull rod 502 using two symmetrically arranged axes. The pad 17 on the push-pull rod 502 can make the pressing rod 706 press and limit. When the pressing rod 706 is parallel to the push-pull rod 502, it is convenient for the user to operate.

[0040] The specific implementation method of this embodiment is as follows: When in use, the user holds the end of the push-pull rod 502 and squeezes the raised end of the pressing rod 706. The other end of the pressing rod 706 lifts the limiting head 705. At the same time, the limiting head 705 drives the limiting rod 704 to move, so that it separates from the current second limiting hole 505. At the same time, the movable plate 702 connected to the limiting rod 704 squeezes the spring 703 in the mounting cavity 701. At this time, the push-pull rod 502 can be unlocked by pushing it on the fixed rod 503 to the first limiting hole 504, releasing the pressing rod 706. Then, under the reset action of the spring 703, the limiting rod 704 is inserted into the first limiting hole 504 of the fixed rod 503, thereby facilitating the push-pull limiting use of the push-pull rod 502 connected to the movable rod 806.

[0041] Example 3

[0042] Please see Figure 8-9This invention provides a technical solution: an angle-adjustable architectural design drawing stand. This invention addresses the technical problems mentioned in the background art by making corresponding improvements. The receiving mechanism 6 includes a connecting block 601. One end of the connecting block 601 is fixedly installed with one of the storage boxes 3 of the drawing board 2. The other end of the connecting block 601 is fixedly installed with a moving block 602. The moving block 602 is slidably connected to one side of the drawing board 2. The side of the moving block 602 away from the connecting block 601 is magnetically connected to the receiving box 603. A drain hole 604 is provided on one side. When the storage box 3 is unfolded, the moving block 602 moves to the opening on one side of the collection tank 401 for easy storage. Conversely, when the storage box 3 is in the stored state, the moving block 602 moves away from the side of the drawing board 2 to prevent damage when not in use or when moving the drawing board. A magnetic piece is embedded on one side of the receiving box 603, which can be attracted and fixed to the moving block 602 in the inner groove below the drain hole 604. When emptying the collected items, the receiving box 603 can be pulled out separately.

[0043] The collection mechanism 4 includes a collection tank 401, which is fixedly installed on one side of the drawing board 2. A side rail 21 is fixedly installed on one side of the drawing board 2. A rectangular hole 403 is opened on one side of the inner wall of the collection tank 401. A slide rod 20 is fixedly installed inside the rectangular hole 403. A scraper 404 is provided on the inner side of one end of the collection tank 401. One side of the scraper 404 is slidably connected to the side rail 21. A pull block 402 is fixedly connected to the other side of the scraper 404. One end of the pull block 402 is slidably connected to the outside of the slide rod 20. With one end closed and the other open, during operation, the scraper 404 is moved by pulling from the closed end of the collection tank 401, which can collect broken pen leads or impurities in the tank and scrape them into the receiving box 603 at the open end of the collection tank 401. The function of the collection tank 401 includes preventing drawing tools from falling to the ground, collecting broken pen leads and eraser impurities, and, in conjunction with the scraper 404 structure, achieving quick cleaning with a single pull. One side of the side rail 21 is inclined, so that no impurities are retained when the drawing board 2 is tilted.

[0044] See Figure 4 A third guide rail 13 is fixedly installed on one side of the drawing board 2. The moving block 602 is slidably connected to the third guide rail 13. A moving hole 14 is opened on the inner wall of one of the box slots 807 of the drawing board 2. One end of the connecting block 601 passes through the moving hole 14. Through the third guide rail 13 on the drawing board 2, the connecting block 601 can drive the moving block 602 to slide on one side of the drawing board 2. Through the moving hole 14 on the drawing board 2, when one of the storage boxes 3 on the drawing board 2 is unfolded, the moving block 602 can be moved to the side of the collection tank 401 to wait for collection.

[0045] The specific implementation method of this embodiment is as follows: The user fully unfolds the storage box 3. On this basis, the connecting block 601 drives the moving block 602 to move to the opening on one side of the collection tank 401. After the drawing is completed, the user operates the pulling block 402. The pulling block 402 drives the scraping block 404 to slide, which can scrape the impurities in the collection tank 401 into the opening on one side of the collection tank 401 in one go, so that they fall into the receiving box 603 through the leakage hole 604 on the moving block 602 for collection, which is convenient for dumping.
