Description

Technical Field

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

[0002] In the interior design process, drafting is required. Interior design drafting typically involves two methods: computer-generated drawing and hand-drawn drawing. Often, a rough draft is created using hand-drawn drawings, which are then further refined using a computer. When drawing by hand, the drawing paper is placed on a drawing table. During use, the drawing table usually has components to hold the paper in place, ensuring it doesn't move or shift during drawing or design. However, in existing drawing tables, the components holding the paper in place are usually fixed and cannot be adjusted according to the size of the paper, thus reducing the flexibility and adaptability of the drawing table and making it inconvenient to use. Secondly, the drawing board in existing drawing tables is usually fixed and cannot be adjusted to suit different user needs, making it difficult for the user to find the most comfortable working posture, which may affect work efficiency and the quality of the work.

A sleeve 4 is fixedly disposed on the movable seat 3. A lifting plate 5 is movably disposed within the sleeve 4. A lifting rod 6 is fixedly disposed on the lifting plate 5. A spring 7 is movably sleeved on the outside of the lifting rod 6. Pull plates 8 are fixedly disposed at the upper ends of two corresponding lifting rods 6, passing through the sleeve 4. A pressing strip 9 is fixedly disposed at the lower end of the pull plate 8. An anti-slip pad 10 is fixedly disposed at the lower end of the pressing strip 9. A fixing block 11 is fixedly disposed at the lower end of the pull plate 8. There are two fixing blocks 11. Fixing teeth 12 are fixedly disposed at the lower end of the fixing blocks 11. There are multiple fixing teeth 12. A toothed groove 13 that mates with the fixing teeth 12 is provided on the drawing board 1. A support platform 14 is hinged to the lower end of the drawing board 1. A drive groove 15 is provided on the support platform 14.

[0029] In this embodiment, when it is necessary to fix the drawing paper, the drawing paper is placed on the drawing board 1. First, the pull plate 8 is pulled upward, the pull plate 8 drives the lifting rod 6 to move, the lifting rod 6 drives the lifting plate 5 to move, the spring 7 is compressed, the pull plate 8 drives the pressing strip 9 and the anti-slip pad 10 to move, so that the anti-slip pad 10 is separated from the drawing board 1. At the same time, the pull plate 8 drives the two fixing blocks 11 to move, the fixing blocks 11 drive the fixing teeth 12 to move out of the tooth groove 13. Then, the pull plate 8 is pulled to move laterally, the pull plate 8 drives the lifting rod 6, the sleeve 4 and the moving seat 3 to move along the moving groove 2, and at the same time drives the fixing blocks 11 and the fixing teeth 12 to move out of the tooth groove 13. The fixed tooth 12, pressing strip 9, and anti-slip pad 10 move, causing the anti-slip pad 10 to move above the edge of the drawing paper. The pull plate 8 is released, and under the push of the spring 7, the lifting plate 5 drives the lifting rod 6, the pull plate 8, the pressing strip 9, and the anti-slip pad 10 to move. The pressing strip 9 presses down, thereby fixing the edge of the drawing paper to the drawing board 1. The anti-slip pad 10 can increase the friction, making the drawing paper more stable. At the same time, the pull plate 8 will drive the fixing block 11 and the fixing tooth 12 to move, so that the fixing tooth 12 is engaged in the corresponding tooth groove 13, thereby fixing the position of the pressing strip 9.

[0030] Please see Figures 1-5As one implementation method for adjusting the angle and height of the drawing board: a drive housing 16 is hinged in the drive slot 15, a motor 17 is fixed in the drive housing 16, a screw 18 is fixed at the drive end of the motor 17, a drive rod 19 is threadedly connected to the screw 18, the drive rod 19 is movably disposed in the drive housing 16, the upper end of the drive rod 19 passes through the drive housing 16 and is hinged to the drawing board 1, a drawer 20 is movably disposed on one side of the support platform 14, and a lifting leg 21 is fixed at the lower end of the support platform 14. There are two lifting legs 21, and a support leg 22 is movably disposed on the outside of each lifting leg 21. The lifting leg 21 is slidably connected to the inside of the lifting leg 21 through a track structure. A lifting chamber 23 is provided on the support leg 22 to cooperate with the lifting leg 21. An electric push rod 24 is fixed in the lifting chamber 23, and the drive end of the electric push rod 24 is fixedly connected to the lifting leg 21.

[0031] More specifically, when the angle of the drawing board 1 needs to be adjusted, the motor 17 is started, which drives the screw 18 to rotate. Since the screw 18 is threadedly connected to the drive rod 19, the drive rod 19 moves along the drive housing 16. One end of the drive rod 19 pushes the drawing board 1, causing the drawing board 1 to rotate around the hinged connection with the support platform 14, thereby adjusting the angle of the drawing board 1. When the height of the drawing board 1 needs to be adjusted, the two electric push rods 24 are started. The electric push rods 24 drive the lifting leg 21 to move along the sliding connection with the support leg 22, thereby adjusting the height of the support platform 14. The support platform 14 then moves the drawing board 1, thereby adjusting the height of the drawing board 1. The drawer 20 can be used to store drawing tools. A controller is set on one side of the support platform 14. All electrical equipment in the device is controlled by the controller. Since the equipment matched with the controller is common equipment and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0032] In summary, when using or operating the entire device: When drawing decoration designs using the entire device, place the drawing paper on the drawing board 1. First, pull the pull plate 8 upwards. The pull plate 8 moves the lifting rod 6, which in turn moves the lifting plate 5. The spring 7 is compressed, and the pull plate 8 moves the pressing strip 9 and the anti-slip pad 10, causing the anti-slip pad 10 to separate from the drawing board 1. Simultaneously, the pull plate 8 moves the two fixing blocks 11, which in turn move the fixing teeth 12 out of the tooth groove 13. Then, pull the pull plate 8 laterally. The pull plate 8 moves the lifting rod 6, the sleeve 4, and the moving seat 3 along the moving groove 2. The fixed block 11, fixed teeth 12, pressing strip 9, and anti-slip pad 10 are moved, causing the anti-slip pad 10 to move above the edge of the drawing paper. The pull plate 8 is released, and under the push of the spring 7, the lifting plate 5 moves the lifting rod 6, pull plate 8, pressing strip 9, and anti-slip pad 10. The pressing strip 9 presses down, thereby fixing the edge of the drawing paper to the drawing board 1. The anti-slip pad 10 can increase the friction, making the drawing paper more stable. At the same time, the pull plate 8 will move the fixed block 11 and fixed teeth 12, causing the fixed teeth 12 to engage in the corresponding tooth groove 13, thus fixing the position of the pressing strip 9.

[0033] When the angle of the drawing board 1 needs to be adjusted, the motor 17 is started. The motor 17 drives the screw 18 to rotate. Since the screw 18 is threadedly connected to the drive rod 19, the drive rod 19 moves along the drive housing 16. One end of the drive rod 19 pushes the drawing board 1, causing the drawing board 1 to rotate around the hinged connection with the support platform 14, thereby adjusting the angle of the drawing board 1. When the height of the drawing board 1 needs to be adjusted, the two electric push rods 24 are started. The electric push rods 24 drive the lifting leg 21 to move along the sliding connection with the support leg 22, thereby adjusting the height of the support platform 14. The support platform 14 moves the drawing board 1, thereby adjusting the height of the drawing board 1. The drawer 20 can be used to store drawing tools. A controller is set on one side of the support platform 14. All electrical equipment in the device is controlled by the controller. Since the equipment matched with the controller is common equipment and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0034] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
