[0002] The project cost display board is a tool specifically used to display information related to project cost, aiming to help viewers quickly and intuitively understand the project's cost structure, control measures, benefit analysis and other contents.

[0003] When users use the display board, they need to stick the drawings of the project cost on the display board. Currently, the display boards on the market are all pasted with tape or double-sided tape. In this way, when the drawings are taken down, the tape or double-sided tape will stick to the drawings, which will damage the drawings and cause damage to the drawings, affecting the subsequent normal use of the drawings, and making it inconvenient for users to display the drawings.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-6 A special display board for engineering cost includes a support frame 1, a display board 2 is arranged above the support frame 1, mounting seats 3 are arranged on both sides of the top of the display board 2, a bidirectional screw rod 31 is installed between the mounting seats 3 on both sides, and screw rod pairs 33 are movably arranged at both ends of the bidirectional screw rod 31.

[0022] One side of the screw rod pair 33 is connected downwardly with a movable plate 4, and a storage cavity 42 is provided inwardly on the side of the movable plate 4 facing the display board 2, and a magnetic block 52 is provided in the storage cavity 42, and an adjustment plate 5 is provided on the back of the magnetic block 52, and the adjustment plate 5 passes through the storage cavity 42 and extends from the other side of the movable plate 4. It should be noted that the movable plate 4 does not contact the display board 2.

[0023] Among them, the bottom of the display board 2 is provided with a guide groove 21, and the bottom of the movable board 4 is inserted into the guide groove 21. Through the setting of the guide groove 21, the movable board 4 can be guided to ensure the stability of the movable board 4 when moving.

[0024] Among them, the upper and lower sides of the movable plate 4 facing away from the display plate 2 are fixedly provided with a fixing seat 41, and the fixing seat 41 is vertically provided with a spring 6 corresponding to the adjustment plate 5. Through the setting of the fixing seat 41 and the spring 6, the pull block 7 and the limit column 71 can be pushed outward.

[0025] The other end of the spring 6 is connected to the pull block 7, and a limit column 71 is vertically arranged on the pull block 7, and the upper and lower ends of the adjustment plate 5 are adapted to open a limit cavity 51 corresponding to the limit column 71. By setting the limit columns 71 and the limit cavity 51 on both sides of the adjustment plate 5, the adjustment plate 5 can be clamped, thereby preventing the adjustment plate 5 from moving toward the display plate 2.

[0026] The display board 2 is made of magnetic material, and the display board 2 and the magnetic block 52 attract each other. Through the mutual attraction between the display board 2 and the magnetic block 52, the magnetic block 52 can be adsorbed on the display board 2, so that the drawings on the display board 2 can be pressed and positioned by the magnetic block 52.

[0027] Among them, one end of the bidirectional screw rod 31 extends out from the mounting seat 3, and a rotating handle 32 is provided at the extending portion of the bidirectional screw rod 31. By rotating the handle 32, the bidirectional screw rod 31 can be controlled to rotate, thereby driving the screw rod pairs 33 on both sides of the bidirectional screw rod 31 to move. It is worth noting that the specific structure and working mode of the bidirectional screw rod 31 and the screw rod pair 33 are all prior arts, and do not belong to the main technical problems solved in this technical solution, so they are not elaborated in this utility model.

[0028] In this embodiment, when the user needs to display the drawing, he can first press the drawing on the middle of the display board 2 by hand. Then, by turning the handle 32, the bidirectional screw 31 can be controlled to rotate, so that the screw pair 33 can be controlled to rotate, and the movable plate 4 can be driven to move to both sides of the drawing. Then, the user can push the pull blocks 7 on the upper and lower sides of the movable plate 4 outward, at which time the springs 6 on both sides are compressed, and the limit columns 71 leave the limit cavity 51. At this time, the clamping of the adjustment plate 5 can be released, and the magnetic block 52 can move to the display board 2 through the magnetic force and be adsorbed on the display board 2, so that the pressing of the drawing can be achieved by the magnetic block 52.

[0029] Furthermore, when the user needs to take out the drawing, the adjustment plate 5 can be pulled outward, and the magnetic block 52 can leave the display board 2. In the process of pulling out the adjustment plate 5, the limit cavities 51 on the upper and lower sides of the adjustment plate 5 will be exposed again, and the limit column 71 can automatically pop outward by the elastic force of the spring 6. When the limit column 7 re-enters the limit cavity 51, the clamping of the adjustment plate 5 can be completed again. Then the user only needs to move the movable plate 4 to the two sides of the display board 2 by turning the handle 32, and finally take down the drawing.

[0030] In the utility model, the movable plate 4 can be moved to both sides of the drawing through the setting of the screw pair 33, the adjustment plate 5 can be clamped through the matching setting between the limit column 71 and the limit cavity 51, and the drawing can be pressed onto the display board 2 through the setting of the magnetic block 52, so that the drawing can be displayed, which will not cause damage to the drawing when it is displayed, and is convenient for users to use the drawing later.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
