Description

Technical Field

[0001] This utility model relates to the technical field of drawing board holders for garden design, and more specifically, it relates to a lifting drawing board holder for garden design. Background Technology

[0002] As an indispensable auxiliary tool in landscape design, planning, and drafting, the drawing board holder directly impacts the designer's work efficiency and health in terms of functionality and ergonomics. However, existing technologies typically employ a fixed-height structure, meaning the height cannot be adjusted once installed. This rigid design fails to accommodate designers of varying heights or adapt to different tasks and environments. Consequently, designers may need to hunch over or stand on tiptoe during extended periods, potentially leading to occupational health issues such as cervical and lumbar spine problems, reducing work comfort and efficiency. This discomfort intensifies over time, particularly in landscape design work requiring detailed drawing over extended periods, ultimately affecting design quality and work progress.

[0003] Secondly, existing drawing board holders are usually designed with a fixed angle. Once the tilt angle is determined, it cannot be changed. This unchanging design concept seriously ignores the principles of ergonomics and the diversity of individual usage habits. Different design tasks may require different working angles. For example, detailed drawings may require a flatter angle to improve accuracy, while conceptual sketches may require a steeper angle to obtain a better overall view. At the same time, different designers have different angle preferences based on their eyesight, usage habits, and work experience. Fixed-angle drawing board holders cannot flexibly adjust the tilt angle of the drawing board according to factors such as personal habits, different work content, and changes in ambient light. This may cause designers to adopt unnatural postures when drawing. Long-term use can easily lead to visual fatigue, neck discomfort, and decreased work efficiency. Especially in large-scale landscape design projects that require continuous work for several hours, these discomforts will accumulate and amplify, and may even lead to occupational diseases.

[0004] Furthermore, while some devices achieve flexible adjustment of the drawing board's tilt angle through the cooperation of certain components, their structural design is too simple and crude, lacking reliable locking devices and having low stability. In actual use environments, especially during outdoor garden site surveys and design processes, these simple adjustment mechanisms are prone to displacement due to external forces such as vibration, wind, accidental collisions, and structural stress. This can lead to unpredictable changes in the adjusted tilt angle. When the angle changes suddenly, it not only affects the accuracy of the drawing and the quality of the design, but may also cause the drawing tools to slip or the design drawings to be damaged, seriously disrupting the workflow and even causing irreparable losses to the design scheme being created. The impact of such sudden angle changes is particularly severe when designing complex garden landscape details, ultimately reducing work efficiency and increasing design costs. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a lifting-type drawing board rack for garden design, which has the following beneficial effects:

[0018] 1. By combining a cylinder and piston rod located below the support plate, the technical challenge of adjusting the fixed height of traditional landscape design drawing board holders is solved. This structure utilizes a telescopic mechanism of cylinder and piston rod, along with a stable guiding system of guide sleeve and guide rod, to achieve flexible adjustment of the drawing board height. When the designer needs to adjust the working height, they simply open the cylinder installed on the base. The cylinder drives the piston rod connected to the output end, causing the support plate to rise or fall. Simultaneously, the support plate drives the bottom-connected guide rod to slide along the guide sleeve, ensuring stability during the lifting process. This allows the height of the bracket and its upper components to be adjusted synchronously with the drawing board. Once the drawing board height is adjusted to a position suitable for the designer's height and work needs, the self-locking cylinder can be closed to lock the height. This design allows designers of different heights to flexibly adjust the drawing board height according to their individual physiological characteristics and work content, avoiding occupational health problems such as cervical and lumbar spine issues caused by prolonged bending or tiptoeing. It significantly improves work comfort and efficiency. Especially in landscape design work that requires long hours of detailed drawing, this humanized design provides designers with a more comfortable working environment, ensuring design quality and work progress.

[0019] 2. By utilizing the sliding engagement between the connecting shafts on both sides of the drawing board and the slide grooves on the support, combined with the rotational connection mechanism between the support rod, the movable rod, and the drawing board, the technical defect of the traditional drawing board frame's fixed angle that cannot be changed is solved. This design uses the method of the support rod sliding through the support and the moving sleeve, and with the coordinated work of components such as the running plate, running block, and drive spring, stepless adjustment of the drawing board's tilt angle is achieved. When it is necessary to adjust the drawing board's tilt angle, by operating the adjusting sleeve, the running plate is no longer clamped to the outer wall of the support rod, thus allowing the support rod to slide along the moving sleeve. Since one end of the support rod is rotatably connected to the drawing board through the movable rod, and the other end of the drawing board is connected to the support through the engagement of the connecting shaft and the slide groove, the technical defect of the traditional drawing board frame's fixed angle that cannot be changed is solved. The frame is slidably connected, and the position change of the support rod directly drives the drawing board to adjust its angle. During the angle change of the drawing board, the connecting shaft slides smoothly in the groove, ensuring that the adjustment process is controllable. This design allows designers to flexibly adjust the tilt angle of the drawing board according to different design task requirements and personal habits. When drawing in detail, a flatter angle can be used to improve accuracy, while a steeper angle can be selected for concept sketches to obtain a better overall perspective. This effectively avoids unnatural working postures caused by fixed angles, reduces visual fatigue and neck discomfort, and greatly improves work efficiency. Especially in large-scale landscape design projects that require continuous work for several hours, this humanized design effectively prevents the occurrence of occupational diseases.

[0020] 3. Through its unique multi-locking system, the technical problem of insufficient stability in traditional adjustable drawing board holders is solved. This structure uses the precise insertion and cooperation of the constraint rod and constraint groove to form the first mechanical lock; the constraint sleeve's limiting mechanism on the outer wall of the constraint plate forms the second anti-loosening safety; the misalignment design of the transformation plate and the compression rod, as well as the rotation positioning function of the transformation hole, form the third protective guarantee. After the drawing board tilt angle is adjusted, the adjusting sleeve rotates in the opposite direction, driving the rotating frame to rotate in the opposite direction. At the same time, the adapting sleeve drives the adapter block to slide in the opposite direction along the adapter groove, so that the inner wall of the running plate clamps the outer wall of the support rod through multiple rubber strips, thereby fixing the position of the support rod; the gravity spring resets and pulls the constraint plate, causing the constraint plate to drive the constraint rod to slide inward, and one end of the constraint rod is reinserted into its original position. Within the constraint groove, the compression spring pushes the constraint sleeve to slide and reset. The inner wall of the constraint sleeve then limits the outer wall of the constraint plate again, preventing the constraint plate and constraint rod from sliding outward. This multi-locking design allows the adjusted drawing board angle to effectively resist external forces such as vibration, wind, accidental collisions, and structural stress, preventing the adjusted structure from shifting or changing. It ensures the drawing board angle remains stable and effectively avoids problems such as decreased drawing accuracy, damaged design quality, slippage of drawing tools, or damage to design drawings caused by sudden changes in angle. Especially in the process of outdoor garden site surveys and design, this stable and reliable locking mechanism provides designers with a safe and stable working platform, ensuring the smooth progress of complex garden landscape detail design, improving work efficiency, and reducing design costs.

The two ends of the attraction spring 15 are connected to the constraint plate 14 and the rotating frame 8, respectively. An inclined groove 16 is opened on the inner side of the moving sleeve 3. An inclined plate 17 is slidably arranged in the inclined groove 16. A running block 18 is fixedly connected to one side of the inclined plate 17. A drive spring 19 is connected to one side of the running block 18. A running plate 20 is connected to the other end of the drive spring 19. A following sleeve 21 is movably arranged in the moving sleeve 3. A following groove 22 is opened on one side of the following sleeve 21. A following block 23 is connected to one side of the running block 18. The following block 23 slides in the following groove 22. One end of the compression spring 6 is connected to the constraint sleeve 4, and the other end of the compression spring 6 abuts against one side of the transformation plate 10.

[0031] A support plate 24 is fixedly installed below the bracket 1, and a base 25 is installed below the support plate 24. A cylinder 26 is detachably installed on the base 25. A piston rod 27 is connected to the output end of the cylinder 26, and the top end of the piston rod 27 is detachably connected to the bottom end of the support plate 24.

[0032] Handles 28 are symmetrically provided on both sides of the support plate 24, and casters 29 are movably provided under the base 25.

[0033] Multiple guide sleeves 30 are detachably provided on the top of the base 25, and guide rods 31 are slidably provided in the guide sleeves 30. The top ends of the multiple guide rods 31 are detachably connected to the bottom end of the support plate 24.

[0034] In this embodiment, when the drawing board holder is needed, the drawing is first fixed on the drawing board 2 using existing technology. Then, the entire device can be pushed by the handle 28, allowing it to move via the bottom moving wheels 29. The bottom moving wheels 29 are connected to the base 25 via a damping shaft. Once the device is in the desired position, the handle 28 is released and the pushing stops. When the height of the drawing board 2 needs to be adjusted, the cylinder 26 installed on the base 25 is opened. The cylinder 26 drives the piston rod 27 connected to the output end, causing the piston rod 27 to lift and lower the support plate 24. The support plate 24 will also cause the bottom connecting guide rod 31 to slide along the guide sleeve 30. At the same time, the support plate 24 will cause the components mounted above it to adjust the height of the drawing board 2. Once the height of the drawing board 2 is adjusted appropriately, the cylinder 26 is closed. The cylinder 26 is a model with a self-locking function.

[0035] Please see Figures 3-5 As a further embodiment of the overall equipment: connecting shafts 32 are fixedly connected to both sides of the plate 2, and a sliding groove 33 is opened on the bracket 1. The connecting shafts 32 slide in the sliding groove 33. Support rods 34 are symmetrically arranged on both sides of the plate 2. A movable rod 35 is connected between the two support rods 34. The two support rods 34 are rotatably connected to the plate 2 through the movable rod 35, and the support rods 34 slide through the bracket 1 and the moving sleeve 3.

[0036] A guide rod 36 is fixedly connected to one side of the running plate 20, and a guide groove 37 is provided in the running block 18. One end of the guide rod 36 is slidably inserted into the guide groove 37.

[0037] The side wall of the sports sleeve 3 is provided with an adapter groove 38, and an adapter block 39 is slidably provided in the adapter groove 38. The inner wall of the adapting sleeve 9 is fixedly connected to the outer wall of the following sleeve 21 through the adapter block 39.

[0038] Multiple anti-slip strips 40 are provided on the outer side of the conversion plate 10, the adjustment sleeve 7 and the constraint sleeve 4, and multiple rubber strips 41 are fixedly connected to the inner side of the running plate 20.

[0039] More specifically, when adjusting the tilt angle of drawing plate 2, first rotate the transformation plate 10 forward, causing the transformation hole 11 to rotate forward to a position concentric with the extrusion rod 5. Then push the constraint sleeve 4, causing the constraint sleeve 4 to gradually slide the extrusion rod 5 into the transformation hole 11. The constraint sleeve 4 will cooperate with the transformation plate 10 to compress the extrusion spring 6, and then the constraint sleeve 4 will gradually stop limiting the outer wall of the constraint plate 14. Then rotate the adjusting sleeve 7 forward, causing the adjusting sleeve 7 to rotate the rotating frame 8 on one side forward. Then the rotating frame 8 will cause the constraint rod 13 and the constraint plate 14 to rotate forward. At this time, the inner wall of the constraint groove 12 compresses one end of the constraint rod 13. Due to the rounded corner design of the inner wall edge of the constraint groove 12 and one end of the constraint rod 13, One end of the rear constraint rod 13 slides out of the constraint groove 12, and the other end of the constraint rod 13 drives the constraint plate 14 to slide outward. The constraint plate 14 drives the gravity spring 15 to stretch outward. At the same time, since the inner wall of the adjusting sleeve 7 and the outer wall of the adapting sleeve 9 are movably connected by threads, and the adaptation block 39 and the adaptation groove 38 limit the rotation of the adapting sleeve 9, the adapting sleeve 9 drives the inner adaptation block 39 to slide along the adaptation groove 38. The adaptation block 39 drives the inner following sleeve 21 to slide. Then, the following sleeve 21 drives the following block 23 to move through the following groove 22. Then, the following block 23 drives the one-sided running block 18 to move. Then, the running block 18 drives the guide rod 36, the guide groove 37, the drive spring 19, and the running plate 20 to move. Furthermore, the running block 18 will cause the inclined plate 17 on the other side to slide along the inclined groove 16. At the same time, the inclined plate 17 will cause the running block 18 to spread outward, so that the running block 18 will cause the following block 23 on one side to slide outward along the following groove 22, thus increasing the distance between the running block 18 and the running plate 20. Then, the drive spring 19 will gradually return to its original position. When the drive spring 19 is fully returned to its original position, the running block 18 will cause the guide groove 37, guide rod 36, drive spring 19 and running plate 20 to slide outward, so that the running plate 20 will no longer clamp the outer wall of the support rod 34. Then, the support rod 34 will slide along the running sleeve. Since one end of the support rod 34 is rotatably connected to the drawing plate 2 through the movable rod 35, and the other end of the drawing plate 2 is connected to the guide groove 37, guide rod 36, drive spring 19 and running plate 20, the running plate 20 will no longer clamp the outer wall of the support rod 34. Then, the support rod 34 will slide along the running sleeve. The connecting shaft 32 and the slide groove 33 are slidably connected to the bracket 1. Then, the support rod 34 will drive the drawing plate 2 to change its angle, thus changing the tilt angle of the drawing plate 2. At the same time, the drawing plate 2 will drive the connecting shafts 32 on both sides to slide in the slide groove 33. When the tilt angle of the drawing plate 2 is adjusted properly, the adjusting sleeve 7 is rotated in the opposite direction. The adjusting sleeve 7 will drive the rotating frame 8 on one side to rotate in the opposite direction. The rotating frame 8 will also drive the constraint rod 13, constraint plate 14 and gravity spring 15 to rotate in the opposite direction. At the same time, due to the threaded fit between the inner wall of the adjusting sleeve 7 and the outer wall of the adapting sleeve 9, the adapting sleeve 9 will drive the fitting block 39 to slide in the opposite direction along the fitting groove 38. Simultaneously, the fitting block 39 will drive the inner following sleeve 21 to slide in the opposite direction. The following sleeve 21 will push the running block 18 on one side to slide in the opposite direction.Furthermore, the running block 18 will cause one side of the guide rod 36, guide groove 37, drive spring 19, and running plate 20 to slide in the opposite direction. At the same time, the running block 18 will cause the other side of the inclined plate 17 to slide in the opposite direction along the inclined groove 16. The inclined plate 17 will also cause one side of the running block 18 to converge inward. Then, the running block 18 will cause one side of the following block 23 to slide inward along the following groove 22. The running block 18 will also cause the guide groove 37, guide rod 36, drive spring 19, and running plate 20 to converge inward. Then, the running plate 20... The inner wall gradually comes into contact with the outer wall of the support rod 34. Then, the distance between the running block 18 and the running plate 20 shortens, causing the guide rod 36 connected to one side of the running plate 20 to slide into the guide groove 37. The running plate 20 and the running block 18 cooperate to gradually press the drive spring 19. Then, the inner wall of the running plate 20 clamps the outer wall of the support rod 34 through multiple rubber strips 41, thus fixing the position of the support rod 34. At the same time, the rotating frame 8 drives the constraint rod 13 and other components to rotate and reset to the original constraint groove 12. At the corresponding position, the gravity spring 15 resets and pulls the constraint plate 14, causing the constraint plate 14 to slide the constraint rod 13 inward. Then, one end of the constraint rod 13 will re-insert into the original constraint groove 12. Then, the constraint sleeve 4 is released, and the compression spring 6 pushes the constraint sleeve 4 to slide and reset. The constraint sleeve 4 will also drive one side of the compression rod 5 to slide and reset, so that the compression rod 5 no longer penetrates into the transformation hole 11. Then, the transformation plate 10 is rotated in the opposite direction, causing the transformation plate 10 to rotate and reset the transformation hole 11 to a position that does not correspond to the compression rod 5. Then, the compression rod 5 limits and supports the constraint sleeve 4 to one side of the transformation plate 10, so that the constraint sleeve 4 cannot slide easily. Then, the inner wall of the constraint sleeve 4 limits the outer wall of the constraint plate 14 again, so that the constraint plate 14 and the constraint rod 13 cannot slide outward. Then, the constraint rod 13 and the constraint groove 12 cooperate to limit and lock the rotating frame 8, so that the rotating frame 8 and the adjusting sleeve 7 cannot rotate accidentally, thereby ensuring the structural stability of the plate 2 after the tilt angle is adjusted, and ensuring the stable use of the plate 2.

[0040] In summary, when using or operating the overall equipment: When the drawing board 2 frame is needed, first fix the drawing onto the drawing board 2 using existing technology. Then, push the overall equipment through the handle 28, allowing it to move via the bottom moving wheels 29. The bottom moving wheels 29 are connected to the base 25 via a damping shaft. Once the equipment is in the desired position, release the handle 28 and stop pushing. When adjusting the height of the drawing board 2, open the cylinder 26 installed on the base 25. The cylinder 26 drives the piston rod 27 connected to the output end, causing the piston rod 27 to lift and lower the support plate 24. The support plate 24 will also cause the bottom connecting guide rod 31 to slide along the guide sleeve 30. Simultaneously, the support plate 24 will cause the components mounted above it to adjust the height of the drawing board 2. Once the height of the drawing board 2 is adjusted appropriately, close the cylinder 26. The cylinder 26 is a model with a self-locking function.

[0041] When adjustment is needed, first rotate the transformation plate 10 clockwise, causing the transformation hole 11 to rotate clockwise to a position concentric with the extrusion rod 5. Then push the constraint sleeve 4, causing the constraint sleeve 4 to gradually slide the extrusion rod 5 into the transformation hole 11. The constraint sleeve 4 will cooperate with the transformation plate 10 to compress the extrusion spring 6, and then the constraint sleeve 4 will gradually stop limiting the outer wall of the constraint plate 14. Then rotate the adjustment sleeve 7 clockwise, causing the rotating frame 8 to rotate clockwise. The rotating frame 8 will then cause the constraint rod 13 and the constraint plate 14 to rotate clockwise. At this time, the inner wall of the constraint groove 12 compresses one end of the constraint rod 13. Due to the rounded corner design of the inner wall edge of the constraint groove 12 and one end of the constraint rod 13, one end of the constraint rod 13 will... The constraint rod 13 slides out of the constraint groove 12, and the other end of the constraint rod 13 will drive the constraint plate 14 to slide outward. The constraint plate 14 will drive the gravity spring 15 to stretch outward. At the same time, since the inner wall of the adjusting sleeve 7 and the outer wall of the adapting sleeve 9 are movably connected by threads, and the adaptation block 39 and the adaptation groove 38 limit the rotation of the adapting sleeve 9, the adapting sleeve 9 will drive the inner adaptation block 39 to slide along the adaptation groove 38. The adaptation block 39 will drive the inner following sleeve 21 to slide. Then the following sleeve 21 will drive the following block 23 to move through the following groove 22. Then the following block 23 will drive the one-sided running block 18 to move. Then the running block 18 will drive the guide rod 36, the guide groove 37, the drive spring 19 and the running plate 20 to move. This will cause the other side inclined plate 17 to slide along the inclined groove 16. At the same time, the inclined plate 17 will cause the running block 18 to spread outward, so that the running block 18 will cause the following block 23 on one side to slide outward along the following groove 22, thus increasing the distance between the running block 18 and the running plate 20. Then, the drive spring 19 will gradually return to its original position. When the drive spring 19 is fully returned to its original position, the running block 18 will cause the guide groove 37, guide rod 36, drive spring 19 and running plate 20 to slide outward, so that the running plate 20 will no longer clamp the outer wall of the support rod 34. Then the support rod 34 will slide along the running sleeve. Since one end of the support rod 34 is rotatably connected to the drawing plate 2 through the movable rod 35, and the other end of the drawing plate 2 is connected through the connecting rod 35... The shaft 32 and the slide groove 33 are slidably connected to the bracket 1. Then, the support rod 34 will drive the drawing plate 2 to change its angle, thus changing the tilt angle of the drawing plate 2. At the same time, the drawing plate 2 will drive the connecting shafts 32 on both sides to slide in the slide groove 33. When the tilt angle of the drawing plate 2 is properly adjusted, the adjusting sleeve 7 is rotated in the opposite direction. The adjusting sleeve 7 will drive the rotating frame 8 on one side to rotate in the opposite direction. The rotating frame 8 will also drive the constraint rod 13, the constraint plate 14, and the gravity spring 15 to rotate in the opposite direction. At the same time, due to the threaded fit between the inner wall of the adjusting sleeve 7 and the outer wall of the adapting sleeve 9, the adapting sleeve 9 will drive the fitting block 39 to slide in the opposite direction along the fitting groove 38. Simultaneously, the fitting block 39 will drive the inner following sleeve 21 to slide in the opposite direction. The following sleeve 21 will push the running block 18 on one side to slide in the opposite direction.Furthermore, the running block 18 will cause one side of the guide rod 36, guide groove 37, drive spring 19, and running plate 20 to slide in the opposite direction. At the same time, the running block 18 will cause the other side of the inclined plate 17 to slide in the opposite direction along the inclined groove 16. The inclined plate 17 will also cause one side of the running block 18 to converge inward. Then, the running block 18 will cause one side of the following block 23 to slide inward along the following groove 22. The running block 18 will also cause the guide groove 37, guide rod 36, drive spring 19, and running plate 20 to converge inward. Then, the running plate 20... The inner wall gradually comes into contact with the outer wall of the support rod 34. Then, the distance between the running block 18 and the running plate 20 shortens, causing the guide rod 36 connected to one side of the running plate 20 to slide into the guide groove 37. The running plate 20 and the running block 18 cooperate to gradually press the drive spring 19. Then, the inner wall of the running plate 20 clamps the outer wall of the support rod 34 through multiple rubber strips 41, thus fixing the position of the support rod 34. At the same time, the rotating frame 8 drives the constraint rod 13 and other components to rotate and reset to the original constraint groove 12. At the corresponding position, the gravity spring 15 resets and pulls the constraint plate 14, causing the constraint plate 14 to slide the constraint rod 13 inward. Then, one end of the constraint rod 13 will re-insert into the original constraint groove 12. Then, the constraint sleeve 4 is released, and the compression spring 6 pushes the constraint sleeve 4 to slide and reset. The constraint sleeve 4 will also drive one side of the compression rod 5 to slide and reset, so that the compression rod 5 no longer penetrates into the transformation hole 11. Then, the transformation plate 10 is rotated in the opposite direction, causing the transformation plate 10 to rotate and reset the transformation hole 11 to a position that does not correspond to the compression rod 5. Then, the compression rod 5 limits and supports the constraint sleeve 4 to one side of the transformation plate 10, so that the constraint sleeve 4 cannot slide easily. Then, the inner wall of the constraint sleeve 4 limits the outer wall of the constraint plate 14 again, so that the constraint plate 14 and the constraint rod 13 cannot slide outward. Then, the constraint rod 13 and the constraint groove 12 cooperate to limit and lock the rotating frame 8, so that the rotating frame 8 and the adjusting sleeve 7 cannot rotate accidentally, thereby ensuring the structural stability of the plate 2 after the tilt angle is adjusted, and ensuring the stable use of the plate 2.
