Abstract
The invention relates to a portable type lever for teaching. The portable type lever comprises a base, wherein the upper surface of the base is in threaded connection with a supporting rod vertical to the base; the supporting rod is provided with a strip-shaped through hole; the through hole is in bolt connection with a transverse rod for measuring; the transverse rod is composed of a left transverse rod and a right transverse rod which are connected with each other by a hinge; and a drawer is arranged on the side wall of the base. The supporting rod of the portable type lever for teaching is provided with the strip-shaped through hole and the foldable transverse rod in bolt connection with the through hole, so that the portable type lever can be carried about very conveniently.
Description
Technical field
The present invention relates to a kind of portable lever for imparting knowledge to students.
Background technology
In existing physics teaching, in a lot of situations of faculty and staff, need student to demonstrate, so that better Classroom theory knowledge is combined with practice.Especially in mechanics teaching, need to use lever apparatus, but common lever teaching tool is simple in structure, be fixed sturcture between cross bar, support bar and base, therefore deposits and carry very difficult, be easy to damage.
Summary of the invention
The technical problem to be solved in the present invention is: for solving the problem of above-mentioned existence, provide a kind of portable lever for imparting knowledge to students, solve the problem that common lever teaching aid cannot folding storage.
The technical solution adopted for the present invention to solve the technical problems is: a kind of portable lever for imparting knowledge to students, comprise base, the base upper surface support bar vertical with base that be threaded, on support bar, offer strip through-hole, on through hole, bolt is connected with the cross bar for measuring, cross bar is made up of left cross bar and right cross bar chain connection, is provided with drawer on base side wall.
Between left cross bar and right cross bar, be provided with for preventing left cross bar and the right cross bar stop means of upset downwards.
On base end face, be fixedly connected with rubber antiskid pad.
The invention has the beneficial effects as follows, of the present invention for offering strip through-hole on the portable lever support bar of imparting knowledge to students and bolt is connected with folding cross bar, greatly conveniently carry.
