DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-7, the present utility model provides a technical solution: a display device for construction project cost management, including a frame body 1. A groove is formed on the front side surface of the frame body 1. A main display panel 2 and two sub-display panels 3 are arranged inside the frame body 1. The main display panel 2 is fixedly connected inside the frame body 1. The two sub-display panels 3 are located at the rear side of the main display panel 2. Through grooves 4 communicating with the inside are formed on both side surfaces of the frame body 1. A first guiding groove 5 is formed on the bottom wall of the groove inside the frame body 1. A bidirectional threaded rod 6 is rotatably connected inside the first guiding groove 5. A motor 7 is fixedly connected to the right side surface of the frame body 1. The output shaft of the motor 7 rotatably penetrates into the inside of the frame body 1 and is fixedly connected to the bidirectional threaded rod 6. Threaded sleeves 8 are respectively sleeved on two opposite threaded portions of the bidirectional threaded rod 6. The first guiding blocks 8 are slidably connected with the first guiding groove 5. Fixed blocks 9 are fixedly connected to the upper surfaces of the two first guiding blocks 8. The two fixed blocks 9 are respectively fixedly connected to the two sub-display panels 3. A receiving groove 10 is formed on the top wall of the groove inside the frame body 1. A dust-proof component is arranged inside the receiving groove 10. When the device is in use, first, start the motor 7 to drive the rotation of the bidirectional threaded rod 6. Drive the sliding of the two first guiding blocks 8 inside the first guiding groove 5 through the rotation of the bidirectional threaded rod 6. Drive the movement of the two fixed blocks 9 through the movement of the two first guiding blocks 8. Drive the movement of the two sub-display panels 3 respectively through the movement of the two fixed blocks 9, so that the two sub-display panels 3 extend out of the frame body 1 through the through grooves 4, finally realizing an increase in the display area. The display area of the device is further increased through the above structure, which is convenient for the staff to choose whether to use the sub-display panel 3 according to the amount of display materials, thus facilitating the staff to display and explain the data, improving the display effect, with high practicality, high flexibility and simple operation, solving the problem of low flexibility of some existing display devices for construction project cost management.

[0029] Furthermore, the dust-proof component includes a winding roller 11 which is rotatably connected to the inside of the receiving groove 10. One end of the winding roller 11 located inside the receiving groove 10 is sleeved with a dust-proof curtain 12 on its outer surface. A driving plate 13 is arranged at the lower end of the dust-proof curtain 12, and a handle is arranged on the surface of the driving plate 13. A second guiding groove 17 is formed in the top wall of the through groove 4, and the second guiding groove 17 extends into the inside of the frame body 1. A second guiding block 18 is slidably connected to the inside of the second guiding groove 17, and a shielding plate 16 is fixedly connected to the lower surface of the second guiding block 18. Sliding grooves 15 extending out of the rear side surface are formed on both sides of the frame body 1, and the sliding grooves 15 communicate with the through groove 4. The shielding plate 16 is slidably connected to the inside of the sliding groove 15. A connecting component is arranged inside the second guiding groove 17. An embedded magnet 14 is arranged on the bottom wall of the inner groove of the frame body 1, and a magnet 14 is also arranged on the lower surface of the driving plate 13. The two magnets 14 are of opposite polarities. When the staff needs to dust-proof the main display panel 2 and the secondary display panel 3, by pulling down the handle on the surface of the driving plate 13, the dust-proof curtain 12 will move downward at this time, so that the winding roller 11 will rotate. When the magnet 14 on the lower surface of the driving plate 13 contacts the magnet 14 arranged inside the frame body 1, the fixing of the dust-proof curtain 12 can be realized. And when the winding roller 11 rotates, it will drive the connecting component to move. At this time, the movement of the connecting component will drive the second guiding block 18 to slide inside the second guiding groove 17, so as to drive the shielding plate 16 to slide inside the sliding groove 15 through the movement of the second guiding block 18, thereby realizing the shielding of the through groove 4 by the two shielding plates 16, and finally realizing the dust-proof of the main display panel 2 and the secondary display panel 3 by the dust-proof curtain 12 and the shielding plate 16. Through the setting of the dust-proof component, the functionality of the device is further improved, avoiding the situation that too much dust will cover the surface of the display panel when the device is idle, thereby reducing the cleaning frequency of the display panel by the staff as much as possible, reducing the workload of the staff, and having high practicability and simple operation.

[0030] Furthermore, both ends of the winding roller 11 rotatably penetrate into the inside of the second guiding groove 17. A fixing ring 21 is fixedly sleeved on one end of the winding roller 11 located inside the second guiding groove 17. A torsion spring 22 is fixedly connected between the fixing ring 21 and the inner wall of the second guiding groove 17, and the torsion spring 22 is sleeved outside the winding roller 11. The movement of the dust-proof curtain 12 causes the winding roller 11 to rotate, so that the torsion spring 22 will deform. When the dust-proof curtain 12 needs to be wound up later, the winding of the dust-proof curtain 12 can be realized by relying on the elastic force of the torsion spring 22 itself, further improving the convenience of the staff's operation and having a good use experience.

[0031] Further, the connecting component includes a threaded rod 19 which is rotatably connected inside the second guiding groove 17. Fixed sleeves of conical gears 20 are provided at the ends of the threaded rod 19 and the winding roller 11 close to each other. The two conical gears 20 are meshed and connected. The dust-proof curtain 12 drives the winding roller 11 to rotate, thereby driving the conical gear 20 on the surface of the winding roller 11 to rotate, and then driving the conical gear 20 on the surface of the threaded rod 19 to rotate. Subsequently, the rotation of the threaded rod 19 drives the two second guiding blocks 18 to slide simultaneously and in the same direction inside the second guiding groove 17, so as to realize that the two baffle plates 16 simultaneously block the through groove 4 during the process of pulling down the dust-proof curtain 12, and the two baffle plates 16 simultaneously open the through groove 4 while winding up the dust-proof curtain 12. The setting of the connecting component reduces the operation steps of the staff and improves the overall practicability and flexibility of the device.

[0032] Further, two second supporting legs 24 are fixedly connected to the lower surface of the frame body 1. A first supporting leg 23 is slidably sleeved outside the second supporting leg 24. An electric push rod 25 is arranged between the first supporting leg 23 and the second supporting leg 24. The electric push rod 25 is a conventional structure, so it will not be described in detail in this text. The shape of the first supporting leg 23 is T-shaped. An inclined support rod 26 is fixedly connected between the cross bar and the vertical bar of the first supporting leg 23. Through the settings of the first supporting leg 23, the second supporting leg 24 and the electric push rod 25, it is convenient for the staff to adjust the height of the frame body 1 according to the actual use requirements, so as to realize the adjustment of the height of the display panel, and increase the flexibility and applicability of the device during use. The setting of the inclined support rod 26 improves the stability of the device during use.

[0033] Working principle:

[0034] When the building engineering cost management display device is in use, starting the motor 7 drives the rotation of the bidirectional threaded rod 6. The rotation of the bidirectional threaded rod 6 drives the two first guiding blocks 8 to slide inside the first guiding groove 5. The movement of the two first guiding blocks 8 drives the movement of the two fixing blocks 9. The movement of the two fixing blocks 9 respectively drives the movement of the two sub-display panels 3, so that the two sub-display panels 3 extend out of the frame body 1 through the through groove 4, and finally the display area is increased.

[0035] When the staff needs to dust-proof the main display panel 2 and the secondary display panel 3, by pulling down the handle on the surface of the driving plate 13, at this time, the dust-proof curtain 12 will move downward, so that the winding roller 11 will rotate. When the magnet 14 on the lower surface of the driving plate 13 contacts the magnet 14 arranged inside the frame body 1, the fixing of the dust-proof curtain 12 can be realized. And when the winding roller 11 rotates, it will drive the connecting assembly to move. At this time, the movement of the connecting assembly will drive the second guiding block 18 to slide inside the second guiding groove 17, so as to drive the shielding plate 16 to slide inside the sliding groove 15 through the movement of the second guiding block 18, thereby realizing the shielding of the through groove 4 by the two shielding plates 16, and finally realizing the dust-proof of the main display panel 2 and the secondary display panel 3 by the dust-proof curtain 12 and the shielding plate 16.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
