Abstract
The utility model relates to a teaching aid, especially relates to a construction stability verification experiment device. The construction stability verification experiment device includes a swinging rack, a hollow column, a column seat matched with the hollow column. The swinging rack comprises a supporting rack with connection board hinged thereon, and a swinging board provided therebetween. The hollow column is equipped with a sliding slot, a regulation screw bolt is equipped in the slot, and a regulation screw nut is disposed on one end of the regulation screw bolt which has a heavy article provided thereon. The utility model comprises a swinging rack, two gravity center height adjustable hollow columns and a column substrate with bottom surface area different from but matched with the bottom surface area of the hollow column. Using the device for demonstration combined with oral explanation, the principle is more likely to be cleared, making students easier to accept and understand.
Description
Technical field
The utility model relates to a kind of teaching aid, relates in particular to a kind of structural stability confirmatory experiment device.
Background technology
The current techique course is carried out enforcement as a required course and in full Zhejiang Province.This is that a science, practicality are all very strong, the subject that practice is carried out under the guidance of scientific theory.As a new course, the current techique teacher mostly also is in the process of the teaching practice while groping.The factor that influences structural stability in current techique " technology and design 2 " in first module second joint " analysis of rock-steady structure " has the height of center of gravity, the size of surface of contact etc., though these scientific discovery rules are simple, but be difficult for making clear also bad acceptance of student and understanding with oral explanation.
Summary of the invention
In order to solve the above problems, the purpose of this utility model provides a kind of simple in structure, strengthens a kind of structural stability confirmatory experiment device that the student understands and accepts.
To achieve the above object, the utility model has adopted following technical scheme: a kind of structural stability confirmatory experiment device, comprise rocking carrier, hollow column and the column base that mates with hollow column, described rocking carrier comprises support, be hinged with web joint on the support, be provided with rocker between the web joint; Described hollow column is provided with chute, and chute is provided with adjusting screw(rod), and an end of adjusting screw(rod) is provided with the adjusting nut, and described adjusting screw(rod) is provided with heavy object.
The side of above-mentioned chute is provided with several screens grooves.
Be provided with gear shaft between the two above-mentioned web joints.
The utility model is not of uniform size and column base that be complementary with hollow column by a rocking carrier, two scalable centers of gravity hollow column of height and base area and hollow column base area; In the demonstration center of gravity when just influencing structural stability, be positioned on the rocker of rocking carrier after nut is provided with the hollow column that two centers of gravity just differ by regulating, shake rocker then, then the higher hollow column of center of gravity falls earlier; When demonstration contact area size influences structural stability, the center of gravity of hollow column is regulated unanimity, after installing the column base on one of them hollow column, be positioned on the rocker of rocking carrier, shake rocker then, then the hollow column that contact area is little falls earlier; So give lessons in conjunction with oral explanation in the demonstration that utilizes the utility model to carry out, can be more clearly clarify wherein reason, the student is better accepted and understand.
