A secondary notice board 216 is fixedly installed between one side of the outer wall of the two groups of sliding frames 215. A second mounting hole 217 is opened on one side of the outer wall of the two secondary notice boards 216. A third bearing 218 is fixedly inserted into the inner surface walls of the two second mounting holes 217. A fixing screw 219 is fixedly inserted into the inner surface walls of the two third bearings 218. A threaded groove 220 is opened on one side of the outer wall of the two secondary fixing frames 213, and the outer wall of the two fixing screws 219 is threadedly connected to the inner wall of the two threaded grooves 220.

[0028] The effect achieved by the entire embodiment 1 is that when more management information needs to be displayed due to the expansion of the project scale or the increase of construction links, the drive motor 210 is first started, and the output end of the drive motor 210 drives the shaft 208 to rotate, and the rotation of the shaft 208 drives the gear 207 to rotate. Since the outer wall of the gear 207 is meshed and connected with two racks 206, the rotation of the gear 207 will cause the two racks 206 to move in opposite directions. Since the tops of the two racks 206 are fixedly connected to the auxiliary fixing frame 213, the movement of the two racks 206 will The two auxiliary fixing frames 213 are respectively driven to be synchronously unfolded on both sides of the main fixing frame 202. Then, by rotating the two fixing screws 219, the two fixing screws 219 can respectively push the two auxiliary bulletin boards 216 to move, so that the two auxiliary bulletin boards 216 are flush with the main bulletin board 203, thereby better expanding the display area of ​​the bulletin board. By adding two auxiliary bulletin boards 216, the information display capability of the construction project management bulletin board can be significantly improved, so that it can display more management information at the same time, avoiding the problem of incomplete or confusing display due to excessive information.

[0029] Embodiment 2, as Figure 2-Figure 5 As shown, the lifting mechanism 1 includes a support frame 101, and two first sliding grooves 102 are provided on one side of the outer wall of the support frame 101, and the inner walls of the two first sliding grooves 102 are slidably embedded with first sliders 103, and the inner wall of the support frame 101 is provided with two first mounting holes 104, and the inner walls of the two first mounting holes 104 are fixedly inserted with first bearings 105, and a threaded rod 106 is fixedly inserted between the insides of the two first bearings 105, and the outer wall of the threaded rod 106 is threadedly connected with a threaded block 107, and the outer wall side of the threaded rod 106 is fixedly connected with a lifting motor 108, one side of the outer wall of the two first sliders 103 is fixedly connected to one side of the outer wall of two of the three connecting plates 201, and one side of the outer wall of the threaded block 107 is fixedly connected to one side of the outer wall of one of the three connecting plates 201.

[0030] The effect achieved by the entire embodiment 2 is that when the display height of the bulletin board does not meet the requirements, the lifting motor 108 is first started, and the output end of the lifting motor 108 drives the threaded rod 106 to rotate. Through the threaded transmission mechanism, the rotation of the threaded rod 106 will drive the threaded block 107 to move up and down in the vertical direction. The movement of the threaded block 107 will then drive the main fixed frame 202 and the main bulletin board 203 to move up and down synchronously, thereby realizing the adjustment of the display height of the main bulletin board 203. Through this adjustment method, the main bulletin board 203 can flexibly adjust its display height according to actual usage scenarios and needs, ensuring that the information can be displayed to the viewer more clearly, thereby improving the readability and dissemination efficiency of the information.

[0031] Working principle: When in use, first start the lifting motor 108 according to the height to be displayed, and the output end of the lifting motor 108 drives the threaded rod 106 to rotate. Since the outer wall of the threaded rod 106 is threadedly connected to the inner wall of the threaded block 107, the rotational movement of the threaded rod 106 is converted into linear movement of the threaded block 107 in the vertical direction, and the threaded block 107 is connected to the main fixed frame 202 through a connecting plate 201, so that the movement of the threaded block 107 drives the main fixed frame 202 and the main bulletin board 203 to move up and down synchronously, so as to achieve precise adjustment of the display height of the main bulletin board 203. In addition, through the cooperation of the two first slide grooves 102 and the two first sliders 103, the stability and smoothness of the main fixed frame 202 in the process of moving up and down are ensured. When more content needs to be displayed due to the expansion of the project scale or the increase of information content, the drive motor 210 is started first, and the output end of the drive motor 210 drives the rotating shaft 208 to rotate, thereby driving the gear 207 rotates, and the outer wall of the gear 207 is meshed with the outer walls of the two racks 206, so the rotation of the gear 207 will drive the two racks 206 to move in opposite directions. Since the tops of the two racks 206 are fixedly connected with the auxiliary fixing frames 213, the movement of the two racks 206 will respectively drive the two auxiliary fixing frames 213 to be synchronously unfolded on both sides of the main fixing frame 202, and the cooperation of the two groups of third sliding grooves 211 and the two groups of third sliding blocks 212 ensures the stability and smoothness of the auxiliary fixing frames 213 during the movement. When the two auxiliary fixing frames 213 move to the extreme position, the staff can rotate the two fixing screws 219 to push the two auxiliary bulletin boards 216 to move, so that the two auxiliary bulletin boards 216 are flush with the main bulletin board 203, thereby displaying more information content. In addition, the close cooperation of the two fixing screws 219 and the two threaded grooves 220 ensures that the auxiliary bulletin boards 216 can remain stable after unfolding and are not easy to shake.
