Example

As shown in Figures 1-3, a drawing placement clamping structure includes a center plate 1, and connecting plates 3 are fixedly connected to the left and right sides of the center plate 1. Multiple second elastic pressure plates 31 are equidistantly installed on the opposite sides of the two connecting plates 3. The second elastic pressure plates 31 are made of iron. A bottom plate 4 is arranged directly below the two connecting plates 3. Two movable wheels 41 with a self-locking function are installed on the bottom surface of the bottom plate 4. Two fixed cylinders 5 are installed on the top surface of the bottom plate 4. A movable column 51 is slidably connected in the fixed cylinder 5. The upper end of the movable column 51 is fixedly connected to the connecting plate 3. Since the connecting plate 3 is slidably connected to the fixed cylinder 5 through the movable column 51, the height of the connecting plate 3 and the center plate 1 can be freely adjusted; a tightening bolt 52 is threadedly connected to the side of the fixed cylinder 5. When the rod of the tightening bolt 52 abuts against the movable column 51, the movable column 51 cannot slide in the fixed cylinder 5, thereby fixing the height of the connecting plate 3 and the center plate 1.

The center plate 1 is a cavity structure. There is a through slot 12 on the bottom surface of the center plate 1. There are two side extension plates 2 slidingly connected in the center plate 1. Threaded columns are installed on the bottom surfaces of the two side extension plates 2. 23. Both threaded posts 23 penetrate through the through groove 12 and are slidingly connected with the through groove 12. The part of the threaded post 23 located below the center plate 1 is threadedly connected with a nut 24. When the nut 24 abuts the bottom surface of the center plate 1, The side extension plate 2 cannot move within the center plate 1; in order to rotate the nut 24 more effortlessly, two hand-twisting plates 25 are installed on the sides of the nut 24 to increase the moment arm. Side baffles 21 are installed on the opposite sides of the two side extension plates 2, and a plurality of first elastic pressure plates 26 are equidistantly installed on the opposite sides of the two side baffles 21.

In order to improve the stability of the side extension plate 2, four support tubes 11 are installed on the bottom surface of the center plate 1. The four support tubes 11 are all slidably connected with support rods 22. The four support rods 22 are fixedly connected to the bottom surfaces of the two side baffles 21 respectively.

Working principle: During specific use, by rotating the hand-tightening plate 25 on the nut 24 anyway, the nut 24 is driven to rotate and move downward, and then the nut 24 is separated from the center plate 1, so that the side extension plate 2 can be inside the center plate 1 Slide, and then move the two side extension plates 2 in opposite directions. After reaching the specified length, the hand-tightening plate 25 on the nut 24 is rotated forward to drive the nut 24 to rotate and move upward, so that the nut 24 is aligned with the center The panels 1 abut, thereby fixing the position of the side extension panels 2 on the center panel 1 .

Then, a plurality of drawings are placed on the central plate 1 and the side extension plate 2 respectively, and the drawings are fixed by the first elastic pressing plate 26 and the second elastic pressing plate 31 .

When it is necessary to adjust the height of the center plate 1, rotate the four tightening bolts 52 in reverse direction to separate the rods of the tightening bolts 52 from the movable column 51, and then move the two connecting plates 3 upward to drive the center plate 1 and the four movable columns 51 move upward. When the center plate 1 is at a designated height, the four tightening bolts 52 are rotated in the forward direction so that the rods of the tightening bolts 52 are in contact with the movable columns 51, thereby causing the movable columns 51 to move upward. It cannot move within the fixed cylinder 5, thereby fixing the heights of the connecting plate 3 and the center plate 1, thereby facilitating viewing and research of multiple drawings.

Among them, since the support tube 11 and the support rod 22 are provided, when the side extension plate 2 moves, the side baffle plate 21 and the support rod 22 will also move, and the support rod 22 will also continue to support the side baffle plate 21, thereby improving the stability of the side extension plate 2 and the side baffle plate 21.

It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
