Background

Physics is the subject of studying the most general laws of motion and basic structures of substances. As the leading subject of natural science, physical studies are as large as the universe and as small as the most basic motion forms and laws of all substances such as basic particles, and therefore, the method becomes the research foundation of other natural science subjects. The theoretical structure of the system fully uses mathematics as the working language of the system, and experiments are used as the only standard for checking the theoretical correctness, which is the most precise natural science subject at present. In physics, many physical formulas are boring and inconvenient to remember, and students are not interested in learning. The teaching aid is used as a model and a tool, can be fine and arouse the interest of students in learning physical knowledge, helps the students to better understand textbook knowledge, and can exercise the manual operation capacity of the students, so that physical experiments in physics are an indispensable course, the physical experiments are related experiments contained in the physical courses in the early high school stage, including electrical experiments, mechanical experiments, thermal experiments, optical experiments and the like, and are commonly used for verifying the theorem law of physical disciplines.

But present physical experiment apparatus, because some instabilities can not make the student to the synthesis of power, the notion of an entity is established to the existence of physical knowledge points such as lever law, when experimenting, hardly reach the accuracy of data, and many people of student a set of progress that can influence the experiment, some experiment teaching aids cause the experimental data of record single very easily, lack the variety, a plurality of physics experiments are accomplished and are needed a plurality of physics teaching aids, it is very troublesome to use, and can not be at the accurate record experimental data after the experiment finishes, experimental data can not the visual expression experiment principle, can not control the size of external force, it is inaccurate to cause experimental data.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel mount for physical teaching experiments to the mount of solving the current physics experiment that proposes in the above-mentioned background art can not make the student establish an entity's notion scheduling problem to the existence of physical knowledge points such as synthesis of force, lever law because of some instabilities.

In order to achieve the above object, the utility model provides a following technical scheme:

Preferably, the base and the supporting rod are made of metal materials.

Preferably, the inside of the supporting rod is of a hollow structure, and the up-and-down adjustment of the demonstration rod can be operated through a fixed knob.

Preferably, the support rod and the dial are fixedly connected with the base through a screw device.

Preferably, the upper surface of the supporting rod can be hung with a pulley, a spring dynamometer and a pendulum ball and a hook weight.

Preferably, the upper surface of the plug is provided with grains.

Compared with the prior art, the utility model provides a novel mount for physical teaching experiments possesses following beneficial effect:

the utility model relates to a novel fixing frame for physics teaching experiments, the inside of a supporting rod is of a hollow structure, the up-and-down adjustment of a demonstration rod can be operated through a fixing knob, the experiment can be conveniently carried out when the required height is adjusted, the demonstration rod can be adjusted back into the supporting rod after the experiment is finished, a protection effect is played for the demonstration rod, a dial is arranged on a base, the experimental data can be conveniently displayed, the experimental effect is better, the right end of the demonstration rod is fixedly provided with a plug, lines are designed on the plug, a rope convenient for swinging the ball is clamped on the plug and can not swing along with the swinging of the swinging ball, the accuracy of the data is ensured, the base and the supporting rod are made of metal materials, the periphery of the bottom end of the base is fixedly provided with a non-slip mat, the weight is not easy to slide down, the stability of the base is aggravated, the utility model has simple and reasonable, the teaching experiment is very light and convenient, and the accessories are all characterized by corrosion resistance and difficult rustiness and are suitable for popularization and use.
