Description
Technical field
The utility model relates to a kind of physics teaching equipment.
Background technology
At present, many concepts in the junior physics teaching material, rule, law are all introduced by experiment, are derived and verify, especially in mechanics teaching, during the research lever equilibrium condition, the length of lever is non-adjustable, obtaining much to organize data just needs the lever of different length to finish, and existing instruments used for education or equipment are bigger owing to volume, and the space that occupies is just big, and the production cost height, be inconvenient to carry, the precision of measurement is also inaccurate.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple in structure, and is easy to use, and the design of extension type ground is easy to carry the physics teaching equipment that measuring accuracy is high.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of physics teaching equipment, comprise base, and be arranged on support bar on the base, and be movably arranged on elevating lever on the support bar, and be arranged on balance stem on the elevating lever, and be arranged on first threaded rod on the balance stem left side, and be arranged on second threaded rod on balance stem the right, and be arranged on the counterbalance weight of the first threaded rod left end and the second threaded rod right-hand member, and be arranged on the pointer in balance stem centre position, and be arranged on the Sign Board at elevating lever top, described Sign Board is provided with scale, and the right side of described support bar is provided with an adjusting knob.
As optimized technical scheme, described elevating lever and balance stem flexibly connect by bolt.
As optimized technical scheme, described balance stem two ends are provided with the threaded hole that supplies first threaded rod and second threaded rod to pass.
The beneficial effect of the utility model physics teaching equipment is: can regulate the height of elevating lever by adjusting knob, first threaded rod and second threaded rod play equilibrium activity, and it is simple in structure, easy to use, the design of extension type ground is easy to carry, the measuring accuracy height is applicable in the physics laboratory.
