Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is an enlarged schematic view of a point a in fig. 1 according to the present invention.
In the figure: 1. a base; 2. a mold plate; 3. adjusting the bolt; 4. an electric telescopic rod; 5. scale lines; 6. a pointing board; 7. a background plate; 8. a mounting cavity; 9. a tension spring; 10. and controlling the switch.
Detailed Description
The technical solution provided by the present invention is clearly and completely described below with reference to the embodiments and the accompanying drawings.
Example 1:
referring to fig. 1 and 2, a traffic and transportation economic development index building model, referring to fig. 1 and 2, comprising a base 1 and a model plate 2, two mounting cavities 8 are formed on two sides of an inner cavity of the base 1, the base 1 is detachably connected with the model plate 2, two support legs are arranged below the model plate 2 and are respectively detachably mounted in the mounting cavities 8, a plurality of groups of electric telescopic rods 4 are arranged at the bottom end of the inner cavity of the base 1, a pointing plate 6 is fixedly connected to the top end of the electric telescopic rods 4, the pointing plate 6 is positioned right in front of the model plate 2, a plurality of groups of scale marks 5 are formed on one side of the model plate 2, a control switch 10 is arranged on the left side of the base 1, the control switch 10 is electrically connected with the electric telescopic rods 4 and an external power supply, when in use, the electric telescopic rods 4 are controlled to work by the control switch 10, the electric telescopic rods 4 drive the pointing plate 6 on the top end to move up and down, both pointing to board 6 can point to not the scale mark 5 of co-altitude, and the data on the scale mark 5 is fed back in real time and is shown the index of different annual transportation economy development, and convenient the observation has just replaced traditional manual regulation and has changed pointing to board 6 height, and the practicality is good.
Referring to fig. 2, the adjusting bolt 3 is inserted in the lateral direction of the outer side of the mounting cavity 8 on the base 1, the bottom end of the adjusting bolt 3 is tightly attached to the side wall of the supporting leg of the model plate 2, and the adjusting bolt 3 transversely penetrates through the side wall of the base 1, when the model plate 2 is mounted or dismounted, the bottom end of the model plate 2 is inserted in the mounting cavity 8, the adjusting bolt 3 is rotated, and the adjusting bolt 3 moves to clamp the model plate 2, so that the structure is simple and the operation is convenient.
