Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] By means of the above structure, when in use, firstly, the two planning tables 9 are installed on the two placing tables 8 for classification or comparative planning display. When storage is needed, the movable block 7 is first rotated by the driving unit, and the rotation of the movable block 7 will cause the placing table 8 to rotate, and the rotation of the placing table 8 will cause the planning table 9 to rotate, thereby making the planning table 9 parallel to the telescopic hydraulic cylinder 23, so that the planning table 9 is stored to reduce the occupied space. At the same time, the driving unit will cause the moving rod 10 to rotate, and the rotation of the moving rod 10 will cause the rotating block 11 to rotate, and the rotation of the rotating block 11 will cause the protective cover 12 to rotate, thereby making the protective cover 12 contact with the placing table 8 to protect the planning table 9. When used again, the movable rod 7 is rotated in the opposite direction by the driving unit, thereby resetting the planning table 9. At this time, the driving unit will cause the moving rod 10 to rotate in the opposite direction, thereby releasing the protection, thereby making the protective cover 12 protect the planning table 9 while storing, and making the protective cover 12 release the protection when the planning table 9 is used. No additional operation is required, and it is not necessary to disassemble and transport it, thereby reducing labor intensity and facilitating use.

[0033] like Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the driving unit includes a motor 2 installed on the side of the moving block 1, and two grooves are provided at the bottom of the moving block 1. The relative inner walls of the two grooves are rotatably installed with movable rods 3, one end of one movable rod 3 is installed on the output shaft of the motor 2, and the two movable rods 3 are installed through transmission elements. The two movable blocks 7 are respectively sleeved on the two movable rods 3, and two moving cavities begin to appear on the moving block 1. The side inner walls of the two moving cavities are rotatably installed with rotating rods 13, and the two rotating rods 13 are installed with the two movable rods 3 through driven elements. Winding rollers 16 are installed at one end of the two rotating rods 13, and steel wire ropes 17 are wound on the two winding rollers 16. Two third circular gears 18 are respectively meshed with two racks 20, and rope holes adapted to the steel wire ropes 17 are provided on the top inner walls of the two grooves and the sides of the two placing tables 8. The placing table 8 is provided with an active cavity, the two moving rods 10 are sleeved with a third circular gear 18, and the two active cavities are provided with a rack 20. The two third circular gears 18 are respectively meshed with the two racks 20, and the other ends of the two steel wire ropes 17 are respectively installed on the sides of the two racks 20, and the sides of the two racks 20 are provided with elastic elements. The advantage of such a configuration is that, through the configuration of the motor 2 and the active rod 3, it is convenient to rotate the placing table 8, and then to store the planning table. Through the configuration of the rotating rod 13, the winding roller 16, the steel wire rope 17, the third circular gear 18 and the rack 20, it is convenient to store the planning table 9 while allowing the protective cover 12 to protect it. When the planning table 9 is used, the protective cover 12 is released and evaded, and no additional operation is required, and it does not need to be disassembled and transported, which is convenient for use.

[0034] like Figure 3 As shown, the transmission unit includes two transmission chambers opened on the moving block 1, one end of the two movable rods 3 respectively extends into the two transmission chambers and is installed with a first bevel gear 4, and the sides of the two transmission chambers close to each other are jointly provided with a transmission hole, and a transmission rod 5 is rotatably installed on the transmission hole, and the transmission rod 5 extends into the two transmission chambers at two ends away from each other and is installed with a second bevel gear 6, and the two first bevel gears 4 are respectively meshed with the two second bevel gears 6. The advantage of such an arrangement is that, through the arrangement of the first bevel gear 4, the transmission rod 5 and the second bevel gear 6, it is convenient to make the two movable rods 3 rotate at the same time.

[0035] like Figure 7 As shown, the elastic element includes two springs 21 installed on the side of the rack 20, and the other ends of the two springs 21 are installed on the inner wall of the side of the active cavity. The advantage of this arrangement is that, through the arrangement of the spring 21, when the planning platform 9 is reset and rotated, the winding roller 16 will rotate in the opposite direction to relax the wire rope 17. At this time, the rack 20 is reset under the action of the spring 21. The reset of the rack 20 will cause the moving rod 10 to reset and rotate in the opposite direction, and then the protective cover 12 will reset and rotate, so that the protection is released and avoidance is performed when the planning platform 9 is used.

[0036] like Figure 7 As shown, two slide bars 19 are installed on the relative inner walls of the two movable cavities, and two racks 20 are slidably mounted on the two slide bars 19 on one side.

[0037] like Figure 4 As shown, the driven element includes a driven cavity opened on the moving block 1, a first circular gear 14 is sleeved on the movable rod 3, one end of the rotating rod 13 extends to the driven cavity and is installed with a second circular gear 15, the first circular gear 14 and the second circular gear 15 are meshed with each other, and the advantage of such an arrangement is that, through the arrangement of the first circular gear 14 and the second circular gear 15, the movable rod 3 rotates and drives the rotating rod 13 to rotate at the same time.

[0038] like Figure 4 As shown, the diameter of the first circular gear 14 is greater than the diameter of the second circular gear 15. The advantage of this arrangement is that the number of rotations of the rotating rod 13 is increased through the diameter ratio of the first circular gear 14 and the second circular gear 15, thereby facilitating the movement of the protective cover 12.

[0039] like Figure 2 As shown, a base 22 is provided below the moving block 1, two telescopic hydraulic cylinders 23 are installed on the top of the base 22, the moving block 1 is installed on the output ends of the two telescopic hydraulic cylinders 23, and a self-locking universal wheel 24 is installed at the bottom of the base 22. The advantage of such a setting is that, through the setting of the base 22 and the telescopic hydraulic cylinder 23, it is convenient to adjust the height of the planning platform 9, so as to facilitate the use of people of different heights, and through the setting of the self-locking universal wheel 24, it is convenient to move the equipment as a whole.

[0040] like Figure 2 As shown, two projecting instruments 25 are installed on the top of the moving block 1, an air pump 26 is installed on the top of the moving block 1, and fixed pipes are installed on the sides of the moving block 1 that are away from each other. The air pump 26 is connected to the two fixed pipes through the air pipe, and a plurality of nozzles 27 are arranged on the two fixed pipes. The advantage of such an arrangement is that, through the arrangement of the projecting instrument 25, it is convenient to simulate a variety of different scenes, and through the arrangement of the air pump 26, the air pipe and the nozzle 27, not only can strong wind weather be simulated, but also the dust on the planning table 9 can be blown away.

[0041] like Figure 1 As shown, a U-shaped protective plate is installed on the top of the moving block 1. The advantage of this arrangement is that the U-shaped protective plate can facilitate the protection of the projection instrument 25, the air pump 26, the hose and the nozzle from the top.

[0042] Working principle of the present invention:

[0043] When in use, the base 22 is first moved by the self-locking universal wheel 24. When it moves to the specified position, the height of the moving block 1 is adjusted by the telescopic hydraulic cylinder 23. The lifting of the moving block 1 will make the planning table 9 lift and lower through the movable rod 3, the movable block 7 and the placement table 8, so as to facilitate the use of people of different heights. Then, the two planning tables 9 are installed on the two placement tables 8 for planning display. When storage is needed, the motor 2 is turned on first. The output of the motor 2 will cause one of the movable rods 3 to rotate. The rotation of one of the movable rods 3 will cause the other movable rod 3 to rotate through the first bevel gear 4, the transmission rod 5 and the second bevel gear 6. The rotation of the two movable rods 3 will cause the movable block 7 to rotate. The rotation of the movable block 7 will cause the placement table 8 to rotate. The rotation of the placement table 8 will cause the planning table 9 to rotate, so that the planning table 9 is parallel to the telescopic hydraulic cylinder 23, so that the planning table 9 is stored and the occupied space is reduced. At the same time, the rotation of the movable rod 3 will cause the first circular gear 14 to rotate. The rotation of the first circular gear 14 will cause the rotating rod 13 to rotate rapidly through the second circular gear 15. The rapid rotation of the rotating rod 13 will cause the storage The winding roller 16 rotates, and the rotation of the winding roller 16 will reel in the wire rope 17. The reeling in of the wire rope 17 will move the rope rack 20, and the movement of the rack 20 will cause the third circular gear 18 to rotate, and the rotation of the third circular gear 18 will cause the moving rod 10 to rotate, and the rotation of the moving rod 10 will cause the rotating block 11 to rotate, and the rotation of the rotating block 11 will cause the protective cover 12 to rotate, so that the protective cover 12 contacts the placement table 8 to protect the planning table 9. When it is used again, the motor 2 will run in the reverse direction, and the reverse operation of the motor 2 will cause the movable rod 3 to rotate in the reverse direction. The movable rod 3 The reverse rotation will reset the planning table 9. At the same time, the reverse rotation of the movable rod 3 will cause the winding roller 16 to rotate in the reverse direction. At this time, the wire rope 17 becomes loose. The loose wire rope 17 will reset the rack 20 under the action of the spring 21. The reset of the rack 20 will reset the protective cover 12, thereby releasing the protection. Therefore, the protective cover 12 protects the planning table 9 while it is stored. When the planning table 9 is used, the protective cover 12 releases the protection and evades the planning table 9. No additional operation is required, and it does not need to be disassembled and transported, which reduces labor intensity and is easy to use.

[0044] 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, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
