Technical Field

[0001] The utility model relates to the technical field of drawing tables, in particular to a novel drawing table. Background Art

[0002] A drafting table is a table with an adjustable tilt angle. It's used by draftspeople to lay out their drawing paper and smoothly complete their drawings. It's commonly used in architectural and product drawing. A drafting table often comes with tools like a ruler and an angle ruler.

[0003] Although the existing drawing table can realize the angle adjustment and position control of the ruler, it does not have the effect of fixing the angle and position after adjustment. It is often necessary to fix the ruler with one hand and then use the other hand to draw, which is not conducive to the use of left and right hands for collaborative office drawing and reduces work efficiency. Therefore, a new drawing table is proposed. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 5 The embodiment of the present invention provides a new drawing table, comprising: a bracket 1, a mounting plate 2 fixedly connected to the bracket 1, a drawing board 3 hingedly connected to one side of the mounting plate 2, a horizontal slide rail 4 fixedly connected to the outside of the drawing board 3, a horizontal slider 5 slidably connected to the inside of the horizontal slide rail 4, a vertical slide rail 6 fixedly connected to the outside of the horizontal slider 5, a vertical slider 28 slidably connected to the inside of the vertical slide rail 6, a connecting plate 10 fixedly connected to the outside of the vertical slider 28, a reducing pipe 1 fixedly connected to the outside of the connecting plate 10 3. The interior of the reducer 13 is slidably connected to a sliding rod 14, the exterior of the sliding rod 14 is fixedly connected to a first disc 16, the exterior of the sliding rod 14 is sleeved with a first spring 18, the bottom end of the sliding rod 14 passes through the bottom of the reducer 13 and is fixedly connected to an angle ruler 17, the top of the sliding rod 14 is fixedly connected to a handle 15, the exterior of the angle ruler 17 is fixedly connected to a right-angle iron piece 26, the exterior of the right-angle iron piece 26 is fixedly connected to the first straight ruler 9 and the second straight ruler 22, and the exterior of the reducer 13 is fixedly connected to a pointer 23.

[0022] Two groups of positioning blocks 8 are fixedly connected to the mounting plate 2 , with each group of positioning blocks 8 having no less than 9 blocks. Two L-shaped support rods 7 are hinged to the bottom of the drawing board 3 .

[0023] When in use, the angle of the drawing board 3 can be adjusted by adjusting the positions of the two L-shaped support rods 7 and the corresponding positioning blocks 8, thereby selecting a suitable use angle.

[0024] When drawing, the left and right positions of the angle ruler 17 can be adjusted by dragging the vertical slide rail 6 and the horizontal slider 5 and the horizontal slide rail 4.

[0025] The outside of the connecting plate 10 is fixedly connected to the shell 19, the inside of the shell 19 is slidably connected to the sliding shaft 20, the outside of the sliding shaft 20 is fixedly connected to the second disc 27, the second disc 27 is slidably connected to the inside of the shell 19, the outside of the sliding shaft 20 is sleeved with a second spring 21, the second spring 21 is located inside the shell 19, one end of the sliding shaft 20 is fixedly connected to the pull handle 11, and the other end of the sliding shaft 20 is fixedly connected to the first rubber block 12.

[0026] The handle 11 is pulled toward the grip 15 by the fingers, so that the first rubber block 12 leaves the vertical slide rail 6 , thereby moving the vertical slider 28 and the connecting plate 10 to adjust the upper and lower positions of the angle ruler 17 .

[0027] The bottom groove of the handle 15 is sleeved on the outside of the reducer 13 , and the first disc 16 is connected to the inside of the reducer 13 in a sliding connection.

[0028] The handle 15 is pressed downward to push the angle ruler 17, so that the upper surface of the angle ruler 17 is separated from the lower surface of the reducer 13, which facilitates the rotation of the angle ruler 17. After the adjustment angle is determined according to the pointer 23, the handle 15 is no longer pressed downward, and the first spring 18 pushes the first disc 16 and the sliding rod 14, thereby re-fitting the upper surface of the angle ruler 17 to the lower surface of the reducer 13. There is friction between the upper surface of the angle ruler 17 and the lower surface of the reducer 13 again, and the first spring 18 drags the angle ruler 17 upward, so that the angle ruler 17 will not rotate at will when it is in contact with the lower surface of the reducer 13.

[0029] In order to further control and limit the movement of the angle ruler 17, the external thread of the reducer 13 is connected to a threaded rod 24 with a handle, and the bottom end of the threaded rod 24 with a handle is fixedly connected to a second rubber block 25. The second rubber block 25 can be adjusted downward to press the angle ruler 17.

[0030] The working steps of this scheme are summarized and sorted out according to the above technical scheme: when in use, the angle of the drawing board 3 can be adjusted by adjusting the position of the two L-shaped support rods 7 and the corresponding positioning blocks 8, so as to select a suitable usage angle. The finger pulls the handle 11 in the direction close to the grip 15, so that the first rubber block 12 leaves the vertical slide rail 6, so that the vertical slider 28 and the connecting plate 10 can be moved to adjust the up and down position of the angle ruler 17. Pressing the grip 15 downward pushes the angle ruler 17, so that the upper surface of the angle ruler 17 and the lower surface of the reducer 13 are separated to facilitate the rotation of the angle ruler 17. After determining the adjusted angle according to the pointer 23, the grip 15 is no longer pressed downward, and the first spring 18 pushes the first disc 16 and the sliding rod 14, so that the upper surface of the angle ruler 17 is re-fitted with the lower surface of the reducer 13. There is friction between the upper surface of the angle ruler 17 and the lower surface of the reducer 13 again, and the first spring 18 drags the angle ruler 17 upward, so that the angle ruler 17 will not rotate at will when it is in a state of being fitted with the lower surface of the reducer 13.
