Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and embodiments of the court's statement:

As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, and Fig. 7, a simple device for making terrain in a model, which consists of a metal bridge 1, a measuring ruler 2, a small parallel ruler 6, and positioning The metal bridge 1 is composed of a bridge body, a bridge frame 3, and a supporting pier 4. The two ends of the bridge body are respectively equipped with a bridge frame 3. The bridge body is an aluminum alloy profile with a rectangular cross-section. There are at least two bridges on the bridge body. Measuring ruler holes 5 (there are 32 measuring ruler holes 5 in Fig. 2, measuring ruler holes 5 can be established as required, such as 2 or 10, and the mutual interval between measuring ruler holes 5 and measuring ruler holes 5 is 20-100 mm ), there are at least two supporting piers 4 below the bridge body (only one supporting pier 4 is drawn in Fig. 7, the measuring ruler 2 can be set according to needs, such as 2 or 10), the number of the measuring ruler 2 is less than or equal to the number of the measuring ruler holes 5, the measuring ruler 2 passes through the measuring ruler hole 5, and the measuring ruler 2 A small parallel ruler 6 parallel to the bridge body of the metal bridge is fixed at the lower end of the metal bridge, a sliding groove 10 is arranged in the small parallel ruler 6, and the slider at the upper end of the positioning pin 7 is located in the sliding groove 10 (the positioning pin can move within a small range , align to the X coordinate).

Described measuring ruler hole 5 is provided with strip material 8 (block or metal) with rubber skin 9; In order to keep measuring ruler stable and unlikely to slip. The utility model can also adopt bolt holes on the side of the bridge body. The bolt holes communicate with the measuring ruler hole 5. The bolts are screwed in the bolt holes. Tightening the bolts can prevent the measuring ruler 2 from slipping, and loosening the bolts can make the measuring ruler 2 adjust. Location.

Measuring ruler 2 is provided with millimeter scale. The upper plane and both sides of the bridge body of the metal bridge are marked with millimeter scales, so as to determine the X coordinate point of the terrain elevation in the model.

The supporting pier 4 is composed of the pier adjusting knob 11, an upper strut, and a lower strut. The lower portion of the upper strut is provided with a lower strut hole, and the upper part of the lower strut is inserted into the lower strut hole of the upper strut. And it is fastened by the pier adjustment knob 11 on the upper strut. (the support pier 4 is fixedly connected with the bridge plate by bolts, and the support pier 4 is a telescopic adjustable structure, which is convenient for moving up and down and also convenient for disassembly; the bridge body is kept flat by the support pier 4).
