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.

[0029] Reference Figure 1-Figure 2 The utility model provides an embodiment of a bidding indication device for engineering cost, comprising a support frame 1, a connecting frame 3 is fixedly connected to the bottom end of the support frame 1, a moving block 4 is slidably connected to the inner wall of the connecting frame 3, a notch is provided on the connecting frame 3, the moving block 4 can be moved vertically along the inner wall, the inner wall of the right end of the moving block 4 is elastically connected to a card block 6 through a reset spring 5, a card slot 7 is provided on the inner side wall of the connecting frame 3, the card slot 7 is provided with two groups of upper end notches and lower end notches, and the upper and lower card slots 7 can be arbitrarily plugged with the card block 6 to position the moving block 4, the side wall of the moving block 4 is hinged with a protective plate 9 through a hinge rod 8, the protective plate 9 is provided with two groups, the protective plates 9 can be brought close to each other in a closed state to protect the bidding screen 10, and the surface of the protective plate 9 is a whiteboard, the content required for the bidding can be written, and the outer wall of the support frame 1 is provided with a display mechanism.

[0030] Reference Figure 1 and Figure 3The outer wall of the protective plate 9 is fixedly connected with a U-shaped frame 11, which mainly supports the entire rotating rod 13 and the wiping plate 15. The inner wall of the U-shaped frame 11 is elastically connected with the rotating rod 13 through a torsion spring 12. The outer wall of the rotating rod 13 is wound with a wiping plate 15 through a winding cloth 14. The wiping plate 15 can erase the font on the protective plate 9. The side wall of the wiping plate 15 is fixedly connected with a guide ring 16. The guide tube 17 cooperates with the guide ring 16 to allow the wiping plate 15 to move vertically, and the moving position will not be offset, so that the wiping plate 15 continues to contact the outer wall of the protective plate 9. The inner wall of the guide ring 16 is slidably connected with a guide tube 17, and the guide tube 17 is fixedly connected At the bottom end of the U-shaped frame 11, the inner wall of the U-shaped frame 11 is fixedly connected to one end of the torsion spring 12. When the rotating rod 13 rotates, the torsion spring 12 is compressed. When resetting, the elastic force of the torsion spring 12 is used to reset the rotating rod 13. The other end of the torsion spring 12 is fixedly connected to the outer wall of the rotating rod 13. The rotating rod 13 is rotatably connected to the inner wall of the U-shaped frame 11. The outer wall of the rotating rod 13 is wound around one end of the winding cloth 14. The winding cloth 14 mainly plays the role of connecting with the wiping plate 15, and the winding cloth 14 has a certain elastic force, which can lead the wiping plate 15 to be rolled up and reset. The other end of the winding cloth 14 is fixedly connected to the top of the wiping plate 15, and the outer wall of the wiping plate 15 contacts the outer wall of the protective plate 9.

[0031] Reference Figure 1-Figure 2 The inner wall of the right end of the moving block 4 is fixedly connected to one end of the return spring 5. When the block 6 moves to the right, the return spring 5 is compressed. When resetting, the block 6 is reset by the elastic force of the return spring 5. The other end of the return spring 5 is fixedly connected to the right end of the block 6. The block 6 is plugged into the inner wall of the card slot 7. The block 6 penetrates and is slidably connected to the inner wall of the moving block 4. The side wall of the moving block 4 is hinged to one end of the hinged rod 8. When the moving block 4 moves downward with one end of the hinged rod 8, the other end is hinged. The rod 8 brings the protective plate 9 closer to each other. On the contrary, when the moving block 4 moves upward with one end of the hinged rod 8, the other end of the hinged rod 8 and the protective plate 9 are separated from each other. The other end of the hinged rod 8 is hinged to the bottom end of the protective plate 9. The protective plate 9 is slidably connected to the inner side wall of the support frame 1. The display mechanism includes a bidding screen 10. The bidding screen 10 is a prior art. The bidding content is displayed in a display manner. No further details are given here. The bidding screen 10 can be detachably mounted on the outer wall of the support frame 1.

[0032] Working principle: First, when you need to protect the bidding screen 10 when it is not in use, you only need to move the block 6 to the right and compress the reset spring 5 to separate the block 6 from the notch of the upper slot 7, and then move the moving block 4 downward to move the hinged rod 8 downward, so that the hinged rod 8 and the protective plate 9 are close to each other. When limiting is required, you only need to release the block 6 and use the reverse elastic force of the reset spring 5 to reset the block 6 to the left, so that the block 6 is plugged into the notch of the lower slot 7, and then use the protective plate 9 to protect the bidding screen 10 from damage caused by collision. When you need to use the bidding screen 10, you only need to follow the above steps to release the limit on the moving block 4, and separate the protective plates 9 from each other by moving the moving block 4 upward with the hinged rod 8, so that the bidding screen 10 is exposed for use, and finally the block 6 and the notch of the upper slot 7 are plugged.

[0033] When the bidding screen 10 is in use, the protective plate 9 can also be used to write the text in the bidding, which increases the practicality of the device. When the text on the protective plate 9 needs to be erased, just pull the wiping plate 15 downward to let the wiping plate 15 slide along the outer wall of the protective plate 9 and wipe it. When the wiping plate 15 moves downward, the wrapping cloth 14 will rotate and spread downward while causing the rotating rod 13 to rotate, so that the rotating rod 13 will compress the torsion spring 12 after rotating. After wiping is completed, release the wiping plate 15 and use the reverse elastic force of the torsion spring 12 to rotate and reset the rotating rod 13 and the wrapping cloth 14, so that the wiping plate 15 returns to its initial state.

[0034] 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.
