Technical Field
[0001] This invention relates to the field of architectural design drawing platform technology, specifically an anti-tipping and easily retractable architectural design drawing platform. Background Technology
[0002] Architectural design drawing platforms are workbenches specifically designed for architects, designers, and drafters for architectural design and drawing work. Some drawing tables have foldable or storage designs, making them easy to store after use and taking up less space.
[0003] Current architectural design and drafting platforms, in order to meet multiple functionalities, such as the ability to adjust angles, often sacrifice storage space due to the tilted angle, making it difficult to accommodate drafting tools. This results in a lack of practicality and impacts the overall efficiency of architectural design and drafting. Summary of the Invention
[0004] The purpose of this invention is to provide an anti-tipping and easily retractable architectural design drawing platform to solve the problem mentioned in the background art that existing drawing platforms cannot satisfy multiple functions simultaneously, resulting in poor platform practicality and affecting the overall efficiency of architectural design drawing.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a tilt-resistant and easily retractable architectural design drawing platform, comprising a tabletop and a base. Movable grooves are provided at both the front and rear ends of the tabletop, and movable blocks are slidably connected inside the movable grooves. A pressing component for pressing drawing paper is provided at the upper end of the movable blocks. A second groove is provided inside the tabletop, and a telescopic component for folding and retracting is provided inside the second groove. A placement component for supporting and placing reference objects and a storage component for storing drawing tools are provided outside the telescopic component. A support column is fixedly connected to the upper end of the base, and a lifting component for adjusting the height is provided inside the support column. An angle adjustment component for adjusting the tabletop angle is provided at the upper end of the lifting component. A movable fixing component is provided at the lower end of the base, and a lighting component is provided at the rear end of the tabletop.
[0006] Furthermore, the pressing assembly includes a pressing rod, a first groove, a shrink spring, a pressing plate, a rotating seat, and a first rotating block. The pressing rod is fixedly connected to the upper end of the moving block. The pressing rod has a first groove inside, and a shrink spring is fixedly connected inside the first groove. The pressing plate is fixedly connected to the lower end of the shrink spring. The rotating seat is fixedly connected to the upper end of the pressing rod, and the first rotating block is rotatably connected inside the rotating seat. By sliding the moving block inside the moving groove, it is positioned at both ends of the drawing paper. Then, the first rotating block inside the rotating seat is rotated, causing the protrusion at its lower end to press the pressing plate downward, thus pressing and fixing the paper. When released, it rotates upward, and the pressing plate retracts upward under the action of the shrink spring. Compared with traditional paper clips, it has a wider pressing range and is easier to operate.
[0007] Furthermore, the telescopic component includes a fixed shaft, a rotating gear, a first rack, a positioning block, and a second rack. The fixed shaft is fixedly connected inside the second groove, and the rotating gear is rotatably connected to the outside of the fixed shaft. The first rack and the second rack are movably connected inside the second groove. The first rack and the second rack mesh with the rotating gear. The positioning block is fixedly connected to the outside of the first rack. When the first rack or the second rack is pulled, it opens outward simultaneously under the action of the rotating gear outside the fixed shaft, and then is positioned by the action of the positioning block, which facilitates the storage of the auxiliary component and saves space.
[0008] Furthermore, the placement component includes a fixed plate, a third groove, a first connecting block, a first connecting shaft, and a support plate. The fixed plate is fixedly connected to the right end of the first rack. The fixed plate has a third groove inside, and the first connecting block is fixedly connected inside the third groove. The first connecting shaft is fixedly connected to the outside of the first connecting block, and the support plate is rotatably connected to the outside of the first connecting shaft. When the first rack extends outward, the surface of the fixed plate can be used to place reference objects needed for drawing. Alternatively, the support plate can be flipped up from inside the third groove under the action of the first connecting shaft for easy support.
[0009] Furthermore, the storage component includes a second connecting shaft, a second connecting block, and a storage slot. The second connecting shaft is rotatably connected inside the second rack, and the second connecting block is fixedly connected to the outside of the second connecting shaft. The storage slot is fixedly connected to the outside of the second connecting block. When the second rack extends out from inside the second groove, the second connecting block and the storage slot can rotate towards the front end under the action of the second connecting shaft, making them closer to the designer and facilitating the retrieval of drawing tools placed inside the storage slot.
[0010] Furthermore, a fixing block is fixedly connected to the right end of the tabletop, and a limit block is slidably connected inside the fixing block. A return spring is provided on the outside of the limit block. Through the limit block and return spring provided inside the fixing block, the fixing plate retracted into the second groove can be restricted when not in use to prevent it from slipping out from the inside.
[0011] Furthermore, the lifting assembly includes a lifting column, a limiting hole, a fixing bolt, a support frame, a first rotating shaft, and a connecting plate. The lifting column is slidably connected inside the support column, and a limiting hole is opened inside the lifting column. A fixing bolt is threadedly connected to the front end of the support column. The support frame is fixedly connected to the upper end of the lifting column, and the first rotating shaft is rotatably connected inside the support frame. A connecting plate is fixedly connected to the outside of the first rotating shaft, and the connecting plate is fixedly connected to the bottom end of the table. By adjusting the height of the lifting column inside the support column and screwing the fixing bolt into the limiting hole, the height of the table can be adjusted to accommodate users of different heights and body types.
[0012] Furthermore, the angle adjustment assembly includes a third connecting block, a second rotating shaft, a second rotating block, a connecting seat, a support shaft, a lifting cylinder, and a telescopic rod. The third connecting block is fixedly connected to the outside of the connecting plate, the second rotating shaft is fixedly connected to the inside of the third connecting block, and the second rotating block is rotatably connected to the outside of the second rotating shaft. The connecting seat is fixedly connected to the lower end of the support frame, the support shaft is rotatably connected to the inside of the connecting seat, the lifting cylinder is fixedly connected to the outside of the support shaft, and a telescopic rod is installed inside the lifting cylinder. The upper end of the telescopic rod is fixedly connected to the second rotating block. When the lifting cylinder on the outside of the support shaft drives the telescopic rod to move upward, the second rotating block connected to the upper end of the telescopic rod will rotate and lift the connecting plate and the upper platform around the first rotating shaft, changing the angle of the platform to adapt to different usage conditions.
[0013] Furthermore, the movable and fixed assembly includes movable wheels, a lead screw, fixed feet, and a rotary knob. The lower end of the base is equipped with movable wheels, and the lead screw is threaded inside the base. The lower end of the lead screw is fixedly connected to the fixed feet, and the upper end of the lead screw is fixedly connected to the rotary knob. By using the movable wheels, the platform can be quickly moved to a suitable area, while rotating the rotary knob at the upper end of the lead screw can make the fixed feet fit with the ground, ensuring stability and preventing tipping.
[0014] Furthermore, the lighting assembly includes a support rod, a lifting rod, a limiting bolt, a third connecting shaft, a lampshade, and a lighting lamp. The support rod is fixedly connected to the rear end of the platform, and the lifting rod is slidably connected inside the support rod. The limiting bolt is threaded into the support rod, and the third connecting shaft is rotatably connected to the upper end of the lifting rod. The lampshade is fixedly connected to the outside of the third connecting shaft, and a lighting lamp is installed inside the lampshade. By adjusting the length of the lifting rod inside the support rod and fixing it with the limiting bolt, the angle of the lampshade outside the third connecting shaft can be adjusted so that the lighting lamp illuminates a suitable area and avoids glare.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. By sliding the moving block inside the moving slot, it is positioned at both ends of the drawing paper. Then, the first rotating block inside the rotating seat is rotated, so that the protrusion at its lower end presses the pressing plate downward, thus pressing and fixing the paper. When released, it is rotated upward, and the pressing plate is retracted upward under the action of the contraction spring. Compared with the traditional paper clamp, it has a wider pressing range, better effect, and is easier to operate.
[0017] 2. The fixed plate can be used to place reference objects needed for drawing on its surface. The support plate can also be flipped up from inside the third groove under the action of the first connecting shaft for easy support. The second connecting block and the storage slot can be rotated to the front end under the action of the second connecting shaft, so that they are closer to the designer and easy to access the drawing tools placed inside the storage slot.
[0018] 3. The telescopic rod is driven to move upward by the lifting electric cylinder. The second rotating block connected to the upper end of the telescopic rod rotates and lifts the connecting plate and the upper platform around the first rotating axis, changing the angle of the platform to adapt to different usage conditions.

A movable fixing component 700 is provided at the lower end of the base 2, and a lighting component 800 is provided at the rear end of the tabletop 1.
[0030] The pressing assembly 100 includes a pressing rod 5, a first groove 6, a shrink spring 7, a pressing plate 8, a rotating seat 9, and a first rotating block 10. The pressing rod 5 is fixedly connected to the upper end of the moving block 4. The pressing rod 5 has a first groove 6 inside, and a shrink spring 7 is fixedly connected inside the first groove 6. The pressing plate 8 is fixedly connected to the lower end of the shrink spring 7. The rotating seat 9 is fixedly connected to the upper end of the pressing rod 5, and the first rotating block 10 is rotatably connected inside the rotating seat 9. By sliding the moving block 4 inside the moving groove 3, it is positioned at both ends of the drawing paper. Then, rotating the first rotating block 10 inside the rotating seat 9 causes its lower protrusion to press the pressing plate 8 downwards, thus pressing and fixing the paper. When released, it rotates upwards, and the pressing plate 8, under the action of the shrink spring 7, moves downwards... The retractable design offers a wider pressing range and easier operation compared to traditional paper clips. The telescopic component 200 includes a fixed shaft 12, a rotating gear 13, a first rack 14, a positioning block 15, and a second rack 21. The fixed shaft 12 is fixedly connected inside the second groove 11, and the rotating gear 13 is rotatably connected to the outside of the fixed shaft 12. The first rack 14 and the second rack 21 are movably connected inside the second groove 11. The first rack 14 and the second rack 21 mesh with the rotating gear 13. The positioning block 15 is fixedly connected to the outside of the first rack 14. When the first rack 14 or the second rack 21 is pulled, it opens outward simultaneously under the action of the rotating gear 13 outside the fixed shaft 12, and then is positioned by the action of the positioning block 15, making it easy to store the auxiliary component and save space.
[0031] Meanwhile, the placement component 300 includes a fixed plate 16, a third groove 17, a first connecting block 18, a first connecting shaft 19, and a support plate 20.

The support plate 20 is rotatably connected to the outside of the first connecting shaft 19. When the first rack 14 extends outward, the surface of the fixed plate 16 can be used to place reference objects needed for drawing. The support plate 20 can also be flipped up from inside the third groove 17 under the action of the first connecting shaft 19 for easy support. The storage component 400 includes a second connecting shaft 22, a second connecting block 23, and a storage groove 24. The second rack... The second rack 21 is internally rotatably connected to a second connecting shaft 22. A second connecting block 23 is fixedly connected to the outside of the second connecting shaft 22. A storage groove 24 is fixedly connected to the outside of the second connecting block 23. When the second rack 21 extends out of the second groove 11, the second connecting block 23 and the storage groove 24 can rotate towards the front end under the action of the second connecting shaft 22, making it closer to the designer and facilitating the retrieval of drawing tools placed inside the storage groove 24. A fixing block 25 is fixedly connected to the right end of the table 1. A limit block 26 is slidably connected inside the fixing block 25. A return spring 27 is provided on the outside of the limit block 26.

The first rotating shaft 33 is rotatably connected inside the support frame 32. The connecting plate 34 is fixedly connected to the outside of the first rotating shaft 33. The connecting plate 34 is fixedly connected to the bottom end of the tabletop 1. By adjusting the height of the lifting column 29 inside the support column 28 and screwing the fixing bolt 31 into the limiting hole 30, the height of the tabletop 1 can be adjusted to accommodate users of different heights and body types. The angle adjustment assembly 600 includes a third connecting block 35, a second rotating shaft 36, and a second rotating block 37. 7. A connecting seat 38, a support shaft 39, a lifting cylinder 40, and a telescopic rod 41 are provided. A third connecting block 35 is fixedly connected to the outside of the connecting plate 34. A second rotating shaft 36 is fixedly connected inside the third connecting block 35. A second rotating block 37 is rotatably connected to the outside of the second rotating shaft 36. A connecting seat 38 is fixedly connected to the lower end of the support frame 32. A support shaft 39 is rotatably connected inside the connecting seat 38. A lifting cylinder 40 is fixedly connected to the outside of the support shaft 39. A telescopic rod 41 is provided inside the lifting cylinder 40. The upper end of the telescopic rod 41 is fixedly connected to the second rotating block 37. When the lifting cylinder 40 outside the support shaft 39 drives the telescopic rod 41 to move upward, the second rotating block 37 connected to the upper end of the telescopic rod 41 will rotate and lift the connecting plate 34 and the upper platform 1 around the first rotating shaft 33, changing the angle of the platform 1 to adapt to different usage conditions.
[0033] In addition, the movable fixing assembly 700 includes movable wheels 42, lead screws 43, fixed feet 44, and a rotating knob 45. The lower end of the base 2 is provided with movable wheels 42, and the lead screw 43 is threadedly connected inside the base 2. The lower end of the lead screw 43 is fixedly connected to the fixed feet 44, and the upper end of the lead screw 43 is fixedly connected to the rotating knob 45. The movable wheels 42 allow the platform to move quickly to a suitable area, while rotating the knob 45 at the upper end of the lead screw 43 allows the fixed feet 44 to contact the ground, ensuring stability and preventing tipping. The lighting assembly 800 includes a support rod 46, a lifting rod 47, and a limit bolt 48. The table 1 is equipped with a third connecting shaft 49, a lampshade 50, and a lighting lamp 51. A support rod 46 is fixedly connected to the rear end of the table 1. A lifting rod 47 is slidably connected inside the support rod 46. A limit bolt 48 is threaded inside the support rod 46. The upper end of the lifting rod 47 is rotatably connected to the third connecting shaft 49. A lampshade 50 is fixedly connected to the outside of the third connecting shaft 49. A lighting lamp 51 is installed inside the lampshade 50. By adjusting the length of the lifting rod 47 inside the support rod 46 and fixing it with the limit bolt 48, the angle of the lampshade 50 outside the third connecting shaft 49 can be adjusted so that the lighting lamp 51 illuminates a suitable area and avoids glare.
[0034] Working principle: When using this drawing platform, the sliding block 4 slides inside the sliding groove 3, positioning it at both ends of the drawing paper. Then, rotating the first rotating block 10 inside the rotating seat 9 causes its lower protrusion to press the pressing plate 8 downwards, thus pressing and fixing the paper. When released, rotating upwards causes the pressing plate 8 to retract upwards under the action of the contraction spring 7. Compared to traditional paper clamps, this provides a wider pressing range and is easier to operate. When the first rack 14 or the second rack 21 is pulled, the rotating gear 13 outside the fixed shaft 12 simultaneously opens outwards. The positioning block 15 then positions the auxiliary components, facilitating storage and saving space. When the first rack 14 extends outward, the surface of the fixing plate 16 can hold reference objects needed for drawing. Alternatively, the support plate 20 can be flipped upward from inside the third groove 17 under the action of the first connecting shaft 19 for support. When the second rack 21 extends outward from inside the second groove 11, the second connecting block 23 and the storage slot 24 can rotate towards the front end under the action of the second connecting shaft 22, making them closer to the designer and facilitating the retrieval of drawings placed inside the storage slot 24. The tool, through the limiting block 26 and return spring 27 set inside the fixing block 25, can restrict the fixing plate 16 retracted into the second groove 11 when not in use, preventing it from slipping out from the inside. By adjusting the height of the lifting column 29 inside the support column 28 and screwing the fixing bolt 31 into the limiting hole 30, the height of the tabletop 1 can be adjusted to accommodate users of different heights and body types. When the lifting electric cylinder 40 on the outside of the support shaft 39 drives the telescopic rod 41 to move upward, the second rotating block 37 connected to the upper end of the telescopic rod 41 will connect the connecting plate 34 and the upper end. The platform 1 rotates and rises upward around the first rotating shaft 33, changing the angle of the platform 1 to adapt to different situations. The movable wheels 42 allow the platform to be quickly moved to a suitable area. The rotating knob 45 at the upper end of the rotating screw 43 allows the fixed feet 44 to be in contact with the ground, ensuring stability and preventing tipping. The length of the lifting rod 47 inside the support rod 46 is adjusted and fixed with the limiting bolt 48. Then, the angle of the lampshade 50 on the outside of the third connecting shaft 49 is adjusted so that the lighting lamp 51 can illuminate a suitable area and avoid glare.
