[0002] Project cost refers to the various fees and costs for construction, civil engineering or other engineering projects in a construction project. These costs usually include labor, materials, equipment, management and other indirect costs. The estimation and management of project cost is crucial to the successful implementation of a project because it directly affects the budget, schedule and quality of the project. Project cost is a complex field involving a variety of data and information, and the data display board can help present this data in an intuitive way for reference and analysis by the project team and stakeholders. Through the data display board, project managers can better monitor and manage project costs, identify problems in a timely manner and make decisions to ensure that the project is completed on time, with quality, and within budget.

[0003] Traditional data display boards are usually fixed to whiteboards or magnetic boards, and these display boards usually present data information in the form of charts, graphs, text or numbers. Traditional data display boards can be hand-painted or printed, and can also be updated and adjusted using stickers, labels or magnetic patches.

[0004] Although the traditional engineering cost data display board displays data through an integrated fixed bracket, it does not take into account the problem that the height of the display board cannot be adjusted due to the fixed height of the support rod. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a foldable engineering cost data display board, which aims to improve the problem that the height of some engineering cost data display boards cannot be adjusted due to the fixed height of the support rods.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foldable engineering cost data display board, comprising a base, a vertical pole fixedly connected to the upper surface of the base, a limiting assembly arranged on the upper surface of the base, a rack fixedly connected to the side wall of the vertical pole, a sliding ring slidably connected to the side wall of the vertical pole, a fixed frame fixedly connected to the side wall of the sliding ring, a rotating shaft rotatably connected inside the fixed frame, a gear fixedly connected to the side wall of the rotating shaft, a worm gear fixedly connected to the side wall of the rotating shaft, a motor fixedly connected to the side wall of the fixed frame, a worm fixedly connected to the output end of the motor, the worm meshing with the worm gear, and the gear meshing with the rack.

[0007] Furthermore, the limiting assembly includes a limiting plate and a slider, the lower surface of the limiting plate is fixedly connected to the upper surface of the base, the side wall of the slider is slidably connected to the inside of the limiting plate, and the side wall of the slider is fixedly connected to the side wall of the sliding ring.

[0008] Furthermore, a display board 1 is arranged on the top of the base, and a connecting block is fixedly connected to one side wall of the display board.

[0009] Furthermore, the side wall of the connection block is fixedly connected to the side wall of the sliding ring, and the display board 1 is fixedly connected to the side wall of the sliding ring through the connection block.

[0010] Furthermore, a magnetic strip 1 is provided on one side wall of the display board, and a hinge is fixedly connected to one side wall of the display board.

[0011] Furthermore, a display board 2 is arranged on the front side of the display board 1, and the display board 2 is connected to the display board 1 through the hinge.

[0012] Furthermore, a second magnetic stripe is provided on the second side wall of the display board, and the second magnetic stripe is in contact with the first magnetic stripe.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the height of the display board can be adjusted easily through the cooperation among the vertical pole, the limit plate, the slider, the rack, the sliding ring, the fixed frame, the rotating shaft, the gear, the worm gear, the motor and the worm, and the problem that the height of some engineering cost data display boards cannot be adjusted due to the fixed height of the support rod is solved.

[0021] 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.

[0022] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a foldable engineering cost data display board, including a base 1, a vertical pole 2 is fixedly connected to the upper surface of the base 1, a limiting assembly is arranged on the upper surface of the base 1, a rack 5 is fixedly connected to the side wall of the vertical pole 2, a sliding ring 6 is slidably connected to the side wall of the vertical pole 2, a fixed frame 7 is fixedly connected to the side wall of the sliding ring 6, a rotating shaft 8 is rotatably connected inside the fixed frame 7, a gear 9 is fixedly connected to the side wall of the rotating shaft 8, a worm gear 10 is fixedly connected to the side wall of the rotating shaft 8, a motor 11 is fixedly connected to the side wall of the fixed frame 7, a worm 12 is fixedly connected to the output end of the motor 11, the worm 12 is meshed with the worm gear 10, and the gear 9 is meshed with the rack 5, and the limiting assembly includes a limiting plate 3 and a slider 4, the lower surface of the limiting plate 3 is fixedly connected to the upper surface of the base 1, the side wall of the slider 4 is slidably connected to the inside of the limiting plate 3, and the side wall of the slider 4 is fixedly connected to the side wall of the sliding ring 6.

[0023] When the height of the display board needs to be adjusted, the worm 12 is driven to rotate by starting the motor 11. As the worm 12 rotates, the shaft 8 rotates accordingly inside the fixed frame 7. The rotation of the shaft 8 further drives the gear 9 to rotate. The rack 5 serves as a linear guide fixed on the vertical pole 2, providing a stable path for the movement of the gear 9. In the process of moving along the rack 5, the gear 9 drives the sliding ring 6 to slide on the side wall of the vertical pole 2, and finally, the height of the display board 13 and the display board 2 17 is changed.

[0024] Reference Figure 3A display board 13 is provided on the top of the base 1, and a connecting block 14 is fixedly connected to the side wall of the display board 13. The side wall of the connecting block 14 is fixedly connected to the side wall of the sliding ring 6. The display board 13 is fixedly connected to the side wall of the sliding ring 6 through the connecting block 14. A magnetic strip 15 is provided on the side wall of the display board 13. A hinge 16 is fixedly connected to the side wall of the display board 13. A display board 2 17 is provided on the front side of the display board 13. The display board 2 17 is connected to the display board 13 through the hinge 16. A magnetic strip 2 18 is provided on the side wall of the display board 2 17. The magnetic strip 2 18 is in contact with the magnetic strip 15.

[0025] Display board 1 13 and display board 2 17 are connected together by hinges 16 so that they can be unfolded or folded when needed. During use, when less data needs to be displayed, display board 2 17 can be folded on the back of display board 1 13 to form a compact whole. Then, the data to be displayed can be written on the surface of display board 1 13. However, when more data needs to be displayed, magnetic stripe 2 18 can be separated from magnetic stripe 1 15 by pulling display board 2 17. Then, through the action of hinges 16, we can deflect display board 2 17 on display board 1 13 to unfold the device. In this way, a larger display space is obtained, and more data can be written and displayed on the surfaces of display board 2 17 and display board 1 13.

[0026] Working principle: When using the device to display the data of engineering cost, the data can be written on the surface of the display board 2 17. When more data needs to be displayed, the display board 2 17 can be pulled to separate the magnetic strip 2 18 from the magnetic strip 15, so that it can be deflected on the display board 13 through the hinge 16, and the device can be unfolded. At this time, the data can be written and displayed on the surface of the display board 2 17 and the display board 13. When the display height of the data needs to be adjusted, the worm 12 can be driven to rotate by starting the motor 11, so that the shaft 8 can rotate inside the fixed frame 7. When the shaft 8 rotates, it will drive the gear 9 to rotate, and the gear 9 will move along the rack 5, and finally drive the sliding ring 6 to slide on the side wall of the vertical pole 2, thereby changing the height of the display board 13 and the display board 2 17.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
