[0002] Bidding is a widely used and organized market transaction behavior in the world. It is a way of buying and selling projects, goods and services in trade. Bidding mainly occurs in the field of construction. Generally, several construction units participate in the project bidding. The bidding unit considers the project duration, cost and quality, and selects the best contractor. The contractor and the contractor need to sign a contract, and the contract is completed. Generally, the bidding information needs to be displayed on display boards. There are many kinds of information display devices currently available on the market, but there are still some shortcomings.
[0003] For example, in actual use, general information display devices display information by using display boards. Generally, the information on the display boards is usually only written on the surface of the display boards, which is easy to be accidentally erased. At the same time, general display boards can only be displayed at a fixed angle and lack the flexibility of adjustment. In addition, if the display boards are left in the air for a long time, a large amount of dust will adhere to the surface, and the dust will block the content of the bidding information display. Therefore, we propose an information display device for bidding to solve the above problems. Utility Model Content

Generally, the information on the display boards is usually only written on the surface of the display boards, which is easy to be accidentally erased. At the same time, the general display boards can only be displayed at a fixed angle and lack the flexibility of adjustment. In addition, when the display boards are placed in the air for a long time, a large amount of dust will adhere to the surface, and the dust will block the content of the bidding information display.

[0024] 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.
[0025] See also Figure 1-4 The utility model provides a technical solution: an information display device for bidding, comprising: a bottom plate 1, a rivet 2, a support rod 3, a first gear 4, a rotating block 5, a rotating disk 6, a second gear 7, a motor 8, a display board body 9, a slide 10, an internal display board 11, a fixed block 12, a threaded rod 13, an electromagnetic slide rail 14, a slider 15, a cleaning brush 16, a controller 17 and a protective cover 18;
[0026] like Figure 1 , Figure 2 and Figure 3As shown in , a base plate 1 is placed on the ground, and rivets 2 are installed on the left and right sides of the inside of the base plate 1. The rivets 2 can firmly fix the base plate 1 to the ground. At the same time, a support rod 3 is installed on the outer side of the upper middle part of the base plate 1, and a first gear 4 and a rotating block 5 are installed on the outer side below the support rod 3. The rotating block 5 is set at an equal angle above the first gear 4. At the same time, the right side of the rotating block 5 slides and contacts the rotating disk 6. A second gear 7 is installed below the rotating disk 6. In addition, a motor 8 is connected to the upper middle part of the rotating disk 6. When the motor 8 is turned on, the motor 8 will cause the rotating disk 6 and the second gear 7 to start rotating. When the rotating disk 6 rotates, it will come into contact with the rotating block 5 above the first gear 4. The first gear 4 and the rotating block 5 will stop rotating, that is, the support rod 3 in the middle of the first gear 4 and the rotating block 5 will also stop rotating. When the second gear 7 starts to rotate, the second gear 7 will be meshed and connected with the first gear 4 on the left side, that is, the second gear 7 will cause the first gear 4 to start rotating. When the first gear 4 rotates, the internal support rod 3 will also rotate. Secondly, a display board body 9 is installed above the support rod 3, that is, an intermittent rotation mechanism is set, which can adjust the rotation angle of the display board body 9 on the support rod 3, which can not only extend the service life of the device but also enable the display board body 9 to rotate in multiple angles, greatly improving the flexibility and practicality of the device.
[0027] like Figure 1 and Figure 4 As shown in, the display board body 9 is set in a transparent shape, and the slide groove 10 is symmetrically set up inside the display board body 9, and the slide groove 10 is in a "T" shape, that is, the inner side of the slide groove 10 can be slidably installed with the internal display board 11, and at the same time, the upper and lower parts of the internal display board 11 are installed with a fixing block 12, and a positioning hole is set inside the fixing block 12. When the internal display board 11 is pushed to move from right to left on the inner side of the slide groove 10, the fixing block 12 is moved to fit tightly with the right side of the display board body 9 up and down. In addition, the right side of the display board body 9 is also provided with positioning holes up and down. Secondly, the positioning hole on the right side of the display board body 9 corresponds to the positioning hole inside the fixing block 12. When the fixing block 12 is tightly fitted with the right side of the display board body 9 up and down, the threaded rod 13 is inserted into the positioning hole and tightened, so that the display board body 9 and the fixing block 12 can be fixed, and the bidding information display is set inside the display board body 9, thereby avoiding the situation where the bidding information is accidentally erased by people;
[0028] like Figure 1 and Figure 3As shown in the figure, an electromagnetic slide rail 14 is arranged on the left side of the display board body 9, a slider 15 is slidingly arranged on the left side of the electromagnetic slide rail 14, and a protective cover 18 is arranged on the outer side of the electromagnetic slide rail 14 for protection. In addition, a controller 17 is installed above the protective cover 18, and a cleaning brush 16 is installed on the right side of the middle front of the slider 15. The cleaning brush 16 is tightly fitted with the surface of the display board body 9. When the controller 17 is turned on, the controller 17 can make the slider 15 move up and down on the left side of the electromagnetic slide rail 14. When the slider 15 moves, it will move up and down with the cleaning brush 16, that is, the cleaning brush 16 can move up and down to clean the surface of the display board body 9, so that the surface of the display board body 9 is kept clean, and dust is effectively prevented from blocking the content displayed by the bidding information inside the display board body 9.
