DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-Figure 8 The utility model provides a technical solution: a drawing display board that is easy to adjust, comprising: a first display board 1, a threaded rod 4 and a connecting block 14, one side of the first display board 1 is movably connected to a second display board 2 through a hinge, and the bottoms of the first display board 1 and the second display board 2 are fixedly connected to a bracket 3;

[0027] One end of the threaded rod 4 is movably connected to the first display board 1 through a bearing, and a threaded block 5 is threadedly connected to the outer side of the threaded rod 4, and one side of the threaded block 5 is connected through a limit rod 6; one end of the limit rod 6 is fixedly connected to the first display board 1, and a clamping rod 7 is fixedly connected to the side of the threaded block 5 away from the limit rod 6, and one end of the clamping rod 7 is connected to the second display board 2; a support foot 8 is connected to the bottom of the bracket 3, and a rotating block 9 is fixedly connected to the top of the support foot 8. The outer side of the rotating block 9 is movably connected to the bracket 3, and a first spring 10 is fixedly connected to the inside of the rotating block 9; one end of the first spring 10 is connected to a ball 11, and the outer side of the ball 11 is connected to the bracket 3, and two groups of grooves matching the ball 11 are opened inside the bracket 3; a first magnet 12 is fixedly connected to one side of the first display board 1, and a second magnet 13 is fixedly connected to one side of the second display board 2, the threaded rod 4 and the threaded block 5 constitute a threaded transmission structure, the threaded block 5 and the limit rod 6 constitute a sliding structure, and the first display board 1 constitutes a rotating structure with the second display board 2 through a hinge.

[0028] In specific implementation, when using surveying and mapping equipment to survey the construction site, one should be fully familiar with various relevant design drawings of the building, so as to understand the relationship between the construction building and the adjacent landforms, as well as the internal dimensions and technical requirements of the building itself. Generally, the drawings will be placed on the drawing display board for the convenience of staff to view. When the drawing display board is stored and carried, the threaded rod 4 is rotated, and the threaded rod 4 will be threaded with the threaded block 5 when it rotates, driving the threaded block 5 to move. When the threaded block 5 moves, it will contact the limiting rod 6. The limiting rod 6 will guide and limit the threaded block 5 to prevent the threaded block 5 from rotating. When the threaded block 5 moves, it will drive the clamping rod 7 to move and break away from the contact with the second display board 2. At this time, the first display board 1 and the second display board 2 can be rotated and folded. In order to prevent the support foot 8 from hitting the first display board 1 and the second display board 2, The folding and storage of the board 2 is affected. By rotating the support leg 8, the rotating block 9 is rotated. When the rotating block 9 rotates, the ball 11 on the outside will contact the bracket 3, and the bracket 3 will move, squeezing the first spring 10 on one side to shrink it, and the ball 11 will be out of contact with the inner groove of the bracket 3. When the ball 11 rotates and contacts another set of grooves inside the bracket 3, the first spring 10 will reset and push the ball 11 to engage with the bracket 3. At this time, the support leg 8 will be folded, and the folding and storage of the first display board 1 and the second display board 2 will not be affected. When the first magnet 12 on one side of the first display board 1 contacts the second magnet 13 on the side of the second display board 2, attraction will be generated, completing the folding and storage of the drawing display board. In this way, the above operation can facilitate the folding and storage of the drawing display board, making it convenient for the staff to carry it.

[0029] See also Figure 1 , Figure 2 and Figure 7One side of the connecting block 14 is connected to the first display board 1 through a slider, and a connecting rod 15 is connected to the inside of the connecting block 14; a second spring 16 is sleeved on the outside of the connecting rod 15, one end of the second spring 16 is connected to the connecting block 14, and a pressing block 17 is fixedly connected to one end of the connecting rod 15. The connecting block 14, the connecting rod 15 and the second spring 16 form an elastic telescopic structure, and the connecting block 14 forms a sliding structure with the first display board 1 through the slider.

[0030] In specific implementation, when using surveying and mapping equipment to survey the construction site, one should be fully familiar with various relevant design drawings of the building, so as to understand the relationship between the construction building and the adjacent objects and the internal dimensions and technical requirements of the building itself. Generally, the drawings will be placed on the drawing display board for the convenience of staff to view. When the drawings are fixed to the drawing display board, by pulling the connecting rod 15, the connecting rod 15 will squeeze the second spring 16 when it moves, so that it will shrink. At this time, the pressing block 17 will move out of contact with the first display board 1, and the movable connecting block 14 can be adjusted according to the size of the drawing. After the adjustment is completed, the connecting rod 15 is released, the second spring 16 will be reset, and the pressing block 17 will be driven to move to press the drawing. At this time, the position of the connecting block 14 will also be fixed at the same time to complete the fixing of the drawing. In this way, the position of the pressing block 17 can be adjusted through the above operation to adapt to drawings of different sizes.

[0031] In summary, when using the easily adjustable drawing display board, firstly, the first display board 1 and the second display board 2 are rotated and unfolded, and fixed by rotating the threaded rod 4, and then the position of the pressing block 17 is adjusted according to the size of the drawing to press the drawing.
