Description

Technical Field

[0001] This utility model relates to the field of drawing board technology, and more specifically, to a drawing board. Background Technology

[0002] Traditional drawing tablets often use a fixed design, making it impossible to adjust the angle of use according to the user's needs and habits. This fixed angle design forces users to work in the same posture for a long time, which can easily cause neck and back fatigue. At the same time, the fixed angle cannot adapt to the needs of different drawing tasks, such as sketching and architectural drawing, which often require different working angles.

[0003] Even if some products adopt an adjustable design, their adjustment mechanisms often suffer from problems such as complex structure, cumbersome operation, and poor stability. The adjustment process requires multiple people to cooperate or consumes a lot of force. The locking mechanism is prone to loosening after adjustment, affecting the safety of use. These problems not only reduce work efficiency but also increase the risk of use. The paper clamping device of existing drawing boards usually adopts a fixed position design, and the clamping position cannot be adjusted. This design cannot adapt to different sizes of drawing paper. When using non-standard sized paper, it either cannot be effectively fixed or needs to be cut. At the same time, the fixed position clamping device is also prone to causing uneven local stress on the paper, resulting in wrinkling or deformation.

[0004] The clamping components have a single fixing method, making it difficult to control the clamping force. Excessive pressure may damage the paper, while insufficient pressure will not effectively fix it. When changing the paper, the clamping device needs to be completely disassembled, which is cumbersome and time-consuming. In addition, the maintenance and adjustment of the clamping components are also difficult, affecting their service life. Utility Model Content

The top frame 3 is installed on the top end of the fixed plate 2. The two ends of the hydraulic cylinder 4 are rotatably connected to the board body 1 and the top frame 3, respectively. The clamping assembly 6 is symmetrically installed on one end face of the board body 1. Press the drawing paper firmly and install the snap-fit ​​mechanism, which includes a snap-fit ​​tube 7, a snap-fit ​​rod 8, a snap-fit ​​hole 9, a rocker arm 10, an orienting block 11, and a pressure groove 12. The snap-fit ​​rod 8 extends into the interior of the snap-fit ​​tube 7, the snap-fit ​​hole 9 is located on the side of the snap-fit ​​rod 8, the rocker arm 10 is rotatably mounted on the side wall of the snap-fit ​​tube 7, the orienting block 11 is longitudinally slidably mounted on the outer wall of the snap-fit ​​tube 7, and the pressure groove 12 is located on the orienting block 11. The top and bottom ends of the pressure groove 12 can press against one end of the rocker arm 10, so that the other end of the rocker arm 10 extends into or away from the snap-fit ​​groove.

[0031] In this embodiment, in the initial state, the plate body 1 is rotatably connected to both sides of the fixed plate 2 via the support base 5. When the drawing angle needs to be adjusted, the hydraulic cylinder 4 starts to work. When the hydraulic cylinder 4 extends, it pushes the plate body 1 to rotate around the support base 5 to achieve the elevation angle adjustment. When the hydraulic cylinder 4 retracts, it drives the plate body 1 to rotate back, which can be adjusted to the required angle. The clamping assembly 6 is symmetrically installed on the end face of the plate body 1 to fix the drawing paper. The top frame 3 provides a stable support point for the hydraulic cylinder 4 to ensure smooth adjustment. The locking rod 8 is inserted into the locking tube 7. The locking hole 9 on the side of the locking rod 8 corresponds to the rocker plate 10 inside the locking tube 7. When the directional block 11 slides on the outer wall of the locking tube 7, when the top of the pressure groove 12 presses against one end of the rocker plate 10, the other end of the rocker plate 10 extends into the locking hole 9 to achieve locking. When the bottom of the pressure groove 12 presses against one end of the rocker plate 10, the other end of the rocker plate 10 leaves the locking hole 9 to release the lock. Multiple sets of locking tubes 7 are fixed to the bottom of the plate body 1 via the connecting plate 18 and communicate with the adjustment hole 19 to provide multi-point support.

[0032] The locking auxiliary mechanism includes a top-loading rotating plate 13, a rotating frame 14, a mating block 15, a spring-loaded pin 16, and a mating groove 17. The top-loading rotating plate 13 is installed at the top end of the directional block 11. The rotating frame 14 is rotatably mounted on the outer wall of the locking tube 7. Multiple sets of spring-loaded pins 16 are installed on the outer wall of the locking tube 7. The mating block 15 is installed at the top end of the rotating frame 14. The mating groove 17 is set on the mating block 15. One end of each spring-loaded pin 16 extends into the mating groove 17, so that the rotating frame 14 rotates stably, so that the top-loading rotating plate 13 and the directional block 11 slide in a direction, and so that the pressing groove 12 presses against one end of the rocker plate 10.

[0033] In this embodiment, the rotating frame 14 is limited to rotating on the outer wall of the clamping tube 7, which drives the mating block 15 at the top. The mating groove 17 on the mating block 15 engages with the spring pins 16 on the outer wall of the clamping tube 7 one by one. The spring pins 16 extend into the mating grooves 17 in sequence to achieve segmented positioning and ensure the stable rotation of the rotating frame 14. The top rotating plate 13 is installed on the top of the directional block 11 and moves with the rotating frame 14, driving the directional block 11 to slide in a direction, controlling the force of the pressure groove 12 on the rocker plate 10. The return spring 23 provides a return force between the connecting plate 18 and the directional block 11. The outer rotating rod 24 facilitates manual operation of the mating block 15.

[0034] Please see Figures 1-5As a supplementary implementation of the drawing board adjustment mechanism, mounting and snap-fit ​​mechanism and snap-fit ​​auxiliary mechanism: A connecting plate 18 is installed at the bottom of the side wall of the snap-fit ​​tube 7, and the connecting plate 18 is fixedly installed at the bottom of the plate body 1. Multiple sets of snap-fit ​​tubes 7 are provided. Adjustment holes 19 are symmetrically opened on the plate body 1, and multiple sets of adjustment holes 19 are provided. The snap-fit ​​tube 7 and the adjustment holes 19 are connected. A lighting component 20 is installed on the top frame 3, and the input end of the lighting component 20 is connected to an external power supply. A connecting frame 21 is installed on the back end face of the fixed plate 2, and the connecting frame 21 is connected to the external support required. Side plates 22 are installed at both ends of the pressing component 6, and one end of the snap-fit ​​rod 8 is connected to the side plate 22. The other end of the snap-fit ​​rod 8 extends through the plate body 1 and different adjustment holes 19, and is quickly snapped with the snap-fit ​​tube 7. A return spring 23 is installed between the connecting plate 18 and the directional block 11. An external rotating rod 24 is installed on the outer end of the mating block 15.

[0035] More specifically, the fixing plate 2 is installed on the bracket via the connecting frame 21, the lighting component 20 is connected to the power supply, the mobility of each mechanism is checked, the hydraulic cylinder 4 is operated to adjust the tilt angle of the plate body 1, and a suitable angle is selected according to the drawing requirements. The support seat 5 is confirmed to be stable in rotation. The drawing paper is placed on the plate body 1, and the paper is fixed by the clamping component 6. The side plates 22 at both ends of the clamping component 6 are connected to the snap-fit ​​rod 8. The snap-fit ​​rod 8 passes through the adjustment hole 19 of the plate body 1 and is inserted into the corresponding snap-fit ​​tube 7. The snap-fit ​​mechanism achieves quick locking. The mating block 15 is rotated by the outer rotating rod 24, and the spring pin 16 enters the mating groove 17 step by step to achieve precise control of the clamping force. The lighting angle can be adjusted at any time, and the paper can be quickly unlocked when it needs to be replaced. The return spring 23 ensures that the mechanism is reliably reset.

[0036] In summary, when the overall equipment is in use or running: when the drawing board adjustment mechanism is running, in the initial state, the board body 1 is rotatably connected to both sides of the fixed plate 2 through the support base 5. When the drawing angle needs to be adjusted, the hydraulic cylinder 4 starts to work. When the hydraulic cylinder 4 extends, it pushes the board body 1 to rotate around the support base 5 to achieve the elevation angle adjustment. When the hydraulic cylinder 4 retracts, it drives the board body 1 to rotate back, which can be adjusted to the required angle. The clamping components 6 are symmetrically installed on the end face of the board body 1 to fix the drawing paper. The top frame 3 provides a stable support point for the hydraulic cylinder 4 to ensure smooth adjustment.

[0037] When the snap-fit ​​mechanism is installed, the snap-fit ​​rod 8 is inserted into the snap-fit ​​tube 7. The snap-fit ​​hole 9 on the side of the snap-fit ​​rod 8 corresponds to the rocker plate 10 inside the snap-fit ​​tube 7. When the directional block 11 slides on the outer wall of the snap-fit ​​tube 7, the top of the pressure groove 12 presses against one end of the rocker plate 10, and the other end of the rocker plate 10 extends into the snap-fit ​​hole 9 to lock. When the bottom of the pressure groove 12 presses against one end of the rocker plate 10, the other end of the rocker plate 10 leaves the snap-fit ​​hole 9 to release the lock. Multiple sets of snap-fit ​​tubes 7 are fixed to the bottom of the plate body 1 through the connecting plate 18 and communicate with the adjustment hole 19 to provide multi-point support.

[0038] When the auxiliary mechanism needs to be engaged, the rotating frame 14 rotates to a limit on the outer wall of the clamping pipe 7, driving the mating block 15 at the top. The mating groove 17 on the mating block 15 engages with the spring pins 16 on the outer wall of the clamping pipe 7 one by one. The spring pins 16 extend into the mating groove 17 in sequence to achieve segmented positioning and ensure the stable rotation of the rotating frame 14. The top rotating plate 13 is installed on the top of the directional block 11 and moves with the rotating frame 14, driving the directional block 11 to slide in a direction, controlling the force of the pressure groove 12 on the rocker plate 10. The return spring 23 provides a return force between the connecting plate 18 and the directional block 11. The outer rotating rod 24 facilitates manual operation of the mating block 15.

[0039] The fixing plate 2 is installed on the bracket via the connecting frame 21. The lighting component 20 is connected to the power supply and the mobility of each mechanism is checked. The hydraulic cylinder 4 is operated to adjust the tilt angle of the plate body 1. The appropriate angle is selected according to the drawing requirements. The support seat 5 is confirmed to be stable in rotation. The drawing paper is placed on the plate body 1 and the paper is fixed by the clamping component 6. The side plates 22 at both ends of the clamping component 6 are connected to the snap-fit ​​rod 8. The snap-fit ​​rod 8 passes through the adjustment hole 19 of the plate body 1 and is inserted into the corresponding snap-fit ​​tube 7. The snap-fit ​​mechanism achieves quick locking. The mating block 15 is rotated by the outer rotating rod 24. The spring pin 16 enters the mating groove 17 step by step to achieve precise control of the clamping force.
