Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-4, which show an auxiliary drawing tool for construction engineering design, including a base plate 1, a telescopic rod 2 and a drawing board 8. The telescopic rod 2 is located above the base plate 1, and two connecting plates 4 are fixed to the top of the base plate 1. Side plates 3 are fixed to both sides of the telescopic rod 2. A mounting shell 5 is fixed to the top of the telescopic rod 2, and a connecting frame 7 is arranged above the mounting shell 5. An adjusting mechanism 6 for adjusting the rotation angle of the drawing board 8 is installed inside the mounting shell 5. A connecting block 9 is fixed to the bottom of the drawing board 8, and a first knob 11 is threadedly penetrated on the surface of the connecting frame 7 and the surface of the connecting block 9 is also penetrated by the first knob 11, and a clamping mechanism 10 for fixing the drawing paper is installed on the top of the drawing board 8.

The adjusting mechanism 6 includes a worm 61, a rotating shaft 62, a worm wheel 63 and a rotating plate 64. The worm 61 is rotatably connected to the inner wall of the mounting shell 5. One end of the worm 61 passes through the outer side of the mounting shell 5 and is fixed with a handle. The worm 61 can be rotated by turning the handle. Both ends of the rotating shaft 62 are rotatably connected to the inner wall of the mounting shell 5. The worm wheel 63 is fixed to the surface of the rotating shaft 62. The worm wheel 63 meshes with the worm 61. The worm 61 can drive the worm wheel 63 to rotate. There are two rotating plates 64 and they are both fixed to the surface of the rotating shaft 62. The top of the rotating plate 64 is fixedly connected to the connecting frame 7 with the worm wheel 63. When rotating, the rotating plate 64 will be driven to rotate at the same time through the rotating shaft 62, so that the connecting frame 7 can drive the drawing board 8 to rotate through the connecting block 9, thereby achieving the angle adjustment effect of the drawing board 8.

The clamping mechanism 10 includes an L-shaped plate 101, a first screw 102 and a clamping plate 103. There are two L-shaped plates 101 and they are both slidably connected to the surface of the drawing board 8. The L-shaped plate 101 can slide on the surface of the drawing board 8. The first screw 102 threadedly penetrates the L-shaped plate 101. Rotating the first screw 102 can make it move on the surface of the L-shaped plate 101. The bottom of the first screw 102 is rotatably connected to the clamping plate 103. The clamping plate 103 is slidably connected to the surface of the L-shaped plate 101. The first screw 102 can drive the clamping plate 103 to move, so that the clamping plate 103 can clamp the drawing paper.

Two top plates 12 are fixed on the top of the drawing board 8, and a second screw 13 is threaded through the surface of the top plate 12. One end of the second screw 13 is rotatably connected to the surface of the L-shaped plate 101. Rotating the second screw 13 can make the second screw 13 move on the surface of the top plate 12. At the same time, the second screw 13 can drive the L-shaped plate 101 to move together, so that the clamping plate 103 can clamp and fix drawing papers of different sizes.

A tightening knob 15 is threaded through the surface of the telescopic rod 2. After the telescopic rod 2 has adjusted its own length, the tightening knob 15 can be rotated to enable the telescopic rod 2 with the adjusted length to obtain a limiting effect.

A second knob 14 is threaded through the surface of the connecting plate 4 on one side, and two slots for cooperating with the second knob 14 are provided on the surface of the side plate 3 on one side. The second knob 14 can enter the inner side of the slots on the surface of the connecting plate 4 and the surface of the side plate 3, so that the telescopic rod 2 can obtain a limiting effect.

Working principle: When in use, the length of the telescopic rod 2 can be adjusted according to the height requirements of the user. After adjustment, the telescopic rod 2 can be limited by tightening the knob 15, and then the drawing paper can be placed on the surface of the drawing board 8, and the first screw 102 can be rotated to limit the drawing paper. Then the operator can adjust the rotation angle of the drawing board 8 according to the use requirements. When adjusting, the handle on one side of the mounting shell 5 is rotated to make the rotating plate 64 rotate with the drawing board 8 through the connecting frame 7 and the connecting block 9, thereby achieving the angle adjustment effect of the drawing board 8. When the device needs to be stored, the first knob 11 is rotated to release the connection between the connecting block 9 and the connecting frame 7. Then place the drawing board 8 on one side of the base plate 1, and translate the drawing board 8 so that the base plate 1 is located on the top of the drawing board 8, and then rotate the second screw 13 to make the clamp 103 clamp the base plate 1, thereby completing the connection between the base plate 1 and the drawing board 8, and then twist out the second knob 14, and rotate the telescopic rod 2 to place the telescopic rod 2 on the surface of the base plate 1, and then adjust the position of the telescopic rod 2 so that the slot on the surface of the side plate 3 can be aligned with the slot on the surface of the connecting plate 4, and then the second knob 14 can be twisted into the slot on the surface of the connecting plate 4 and the side plate 3, thereby completing the connection between the telescopic rod 2 and the base plate 1, so that the device can save more space when carried.
