Roadbed planning model convenient to observe and used for highway design

Abstract

The invention provides a road design roadbed planning model convenient to observe, and relates to the technical field of road design, the road design roadbed planning model comprises a cross frame, the front end of the cross frame is provided with a vertical frame; a sliding groove is formed in the front side of the vertical frame. A convex block is arranged at the bottom of the front side of the vertical frame; a lower sliding piece is slidably mounted in the middle of the front side of the vertical frame; a linkage rod is arranged at the bottom end of the front side of the lower sliding piece. A stroke piece is arranged on the front side of the driving rack; the stroke piece is of an inclined structure. A stroke groove is formed in the lower position of the front side of the stroke piece. When a user leaves a design area, the model plate can automatically rotate to reduce the occupied space of the model plate, the occupied space area of the planning model during storage is reduced, and the problems that folding and shrinking work of an existing roadbed planning model needs to be completed manually and exclusively, and folding and shrinking cannot be completed when the user does not use the roadbed planning model are solved. And the roadbed planning model can automatically reduce the occupied area.

Description

technical field [0001] The invention relates to the technical field of highway design, in particular to a roadbed planning model for highway design that is convenient for observation. Background technique [0002] When designing highways, most roadbeds need to be planned, and roadbed planning requires the use of planning models. [0003] However, as far as the current traditional roadbed planning model is concerned, when the existing roadbed planning model is stored and used, it occupies a large storage area, and it is impossible to conveniently fold the roadbed planning model to reduce space, and the existing roadbed planning model Even if the model can be folded, its folding and shrinking work needs to be done manually manually. It is impossible to automatically reduce the occupied area of ​​the subgrade planning model when the user is not using the subgrade planning model. Contents of the invention [0004] In view of this, the present invention provides an easy-to-obs...
