DETAILED DESCRIPTION

[0018] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0019] Example

[0020] See also Figure 1-3 ,The utility model provides a technical solution: a national land space planning model;

[0021] This case aims to provide a land space planning model that is easy to move and display. Most existing space planning models are built on fixed brackets or placement boards, which have poor display effects and are not easy to move.

[0022] Based on the above problems, the components in this case include a box body 1, self-locking universal wheels 2 are arranged at the four corners of the bottom of the box body 1, a scissor frame 3 is installed on the lower side of the box body 1, the top of the scissor frame 3 is connected to a lifting plate 4, an electric rotating seat 5 is arranged on the top of the lifting plate 4, and the top of the electric rotating seat 5 is connected to a model body 6, movable covers 7 are rotatably connected to both sides of the top of the box body 1, a connecting component is arranged on the inner side of the movable cover 7, a plug interface 8 is arranged on one side of the box body 1, a strip groove 9 is arranged on the top of the movable cover 7, an adjusting rod 10 is rotatably connected inside the strip groove 9, and a plug piece 11 is rotatably connected to one end of the adjusting rod 10, and the plug piece 11 is plugged into the plug interface 8;

[0023] The connecting assembly includes: a lock buckle 12, a fixing block 13, a spring rod 14 and a limiting piece 15;

[0024] The lock buckle 12 is installed on one side of the top of the movable cover 7, the fixed block 13 is installed on one side of the top of the movable cover 7, the top of the lock buckle 12 is provided with a rectangular through hole matching the fixed block 13, one end of the spring rod 14 is connected to the top of the fixed block 13, and the bottom of the limit piece 15 is rotatably connected to the top of the spring rod 14;

[0025] It should be noted that the model body 6 is fixed on the top of the electric rotating seat 5, and the electric rotating seat 5 has a built-in motor. This technology is a prior art and is well known to those skilled in the art, so no unnecessary details are given. During the display process, the two movable covers 7 are first opened, and the adjusting rod 10 located inside the strip groove 9 is unscrewed, and the length of the adjusting rod 10 is adjusted. A row of positioning holes and positioning pins are provided at the telescopic part of the adjusting rod 10. After the length adjustment of the adjusting rod 10 is completed, its length can be fixed. At this time, the insert 11 is plugged into the plug interface 8, and the adjusting rod 10 can support the movable cover 7. The surrounding personnel can place lighter debris on the top of the movable cover 7, and at the same time control the operation of the electric push rod 18 inside the scissor frame 3, and drive the model body 6 to rise through the lifting plate 4, so that the model body 6 extends out from the inside of the box body 1, and cooperates with the electric rotating seat 5, so that the surrounding personnel can observe the model body 6 in all directions, thereby increasing the model display effect;

[0026] When the model body 6 needs to be moved, the electric push rod 18 and the scissor frame 3 are used to drive the model body 6 to retract into the box body 1, and then the adjustment rod 10 is reset and screwed into the strip groove 9, and the two movable covers 7 are closed. At this time, the rectangular through hole on the top of the lock buckle 12 is plugged into the fixed block 13, and then the operator rotates the limit plate 15 upward, and the reaction force generated by the stretching of the spring rod 14 can make the limit plate 15 tightly pressed at the plug-in point between the lock buckle 12 and the fixed block 13, so as to prevent the movable cover 7 from being opened by external force during the movement of the box body 1. At this time, the operator can use the movable handrail 16 to cooperate with the self-locking universal wheel 2 to move the box body 1 and the model body 6 inside the box body 1, and at the same time, the box body 1 and the movable cover 7 can protect the model body 6 during the movement;

[0027] Telescopic rods 17 are provided on both sides of the scissor frame 3, and the two ends of the telescopic rods 17 are respectively connected to the bottom of the lifting plate 4 and the inner wall of the bottom of the box body 1, which can increase the stability of the lifting plate 4 during the lifting movement.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
