Description
Technical field
This utility model is related to technical field of motors, and specially one kind freely lands motion test device of motion.
Background technology
Physics full name physicss.Physicss be study the most basic structure of natural world, most common interaction, most one
As the characteristics of motion and the laboratory facilities for being used and method of thinking natural science.In the modern times, physicss have become nature
One of most basic subject in science.It is referred to as law of physics through the law of physics of a large amount of strict experimental verifications.So
And as other many theory of natural science, these laws can not be proved to, its correctness can only be through the experiment of repetitiousness
To check.In physical teaching course, teacher needs, with the uninteresting description of language, to learn when explanation freely lands motor process
The bad understanding of life, teacher are worked hard very much, and work efficiency is low, at present, lack a kind of ocular demonstration of energy on the market and freely land fortune
Dynamic teaching aid.
Utility model content
The purpose of this utility model is to provide one kind freely to land motion test device of motion, to solve in above-mentioned background technology
The problem of proposition.
For achieving the above object, this utility model provides following technical scheme：One kind freely lands motion test device of motion, wraps
Operating board and bearing are included, the corner lower end of the operating board is installed with supporting leg, and the middle part upper end of the operating board is fixed
Montant is installed, the front side wall of the montant is provided with scale value, the fixed peace in the left and right sides of the upper end montant of the operating board
Equipped with corrugated tubing, the inside of the corrugated tubing is mounted on threaded rod, and the top of the threaded rod is solid with the internal ring lower end of bearing
Fixed to connect, the outer shroud upper end of the bearing is provided with by connecting rod puts thing plate.
Preferably, the upper end of the operating board is provided with rubber layer.
Preferably, the left side upper ends of the operating board have workbox.
Preferably, the middle part outer wall of the threaded rod is equipped with handss and twists bar.
Compared with prior art, the beneficial effects of the utility model are：This freely lands motion test device of motion, can be by two
Put thing plate and identical or different height is adjusted to by threaded rod, identical height or differing heights are carried out to different experiments thing block
Experiment with falling objects, simple structure are easy to operate；The elastic reaction of rubber layer has cushioning effect, prevents experiment thing block from smashing
Operating board, improves the service life of the device；The stubborn bar of handss is easy to operate threaded rod.Therefore this freely lands exercise test dress
Put, the experiment with falling objects of identical height or differing heights can be carried out to different experiments thing block, simple structure is easy to operate, makes
With life-span length, with the very strong suitability, it is adapted to large-scale promotion.
Description of the drawings
Fig. 1 is this utility model structural representation.
In figure：Thing is put in 1 operating board, 2 supporting legs, 3 montants, 4 scale values, 5 corrugated tubings, 6 threaded rods, 7 bearings, 8 connecting rods, 9
Plate, 10 rubber layers, 11 workboxes, 12 handss twist bar.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Fig. 1 is referred to, this utility model provides a kind of technical scheme：One kind freely lands motion test device of motion, including behaviour
Make platform 1 and bearing 7, the corner lower end of the operating board 1 is installed with supporting leg 2, and the middle part upper end of the operating board 1 is fixed
Montant 3 is installed, the front side wall of the montant 3 is provided with scale value 4, and the left and right sides of the upper end montant 3 of the operating board 1 is solid
Dingan County is equipped with corrugated tubing 5, and the inside of the corrugated tubing 5 is mounted on threaded rod 6, and the top of the threaded rod 6 is interior with bearing 7
Ring lower end is fixedly connected, and the outer shroud upper end of the bearing 7 is provided with by connecting rod 8 puts thing plate 9.
Specifically, the upper end of the operating board 1 is provided with rubber layer 10, and there is the elastic reaction of its rubber layer 10 buffering to make
With, prevent test thing block smash operating board 1, improve the service life of the device.
Specifically, the left side upper ends of the operating board 1 have workbox 11, are easy to deposit experimental apparatus.
Specifically, the middle part outer wall of the threaded rod 6 is equipped with handss and twists bar 12, and the stubborn bar 12 of handss is easy to operate threaded rod 6.
This freely lands motion test device of motion, can put thing plate 9 by two and be adjusted to identical or different height by threaded rod 6
Degree, carries out the experiment with falling objects of identical height or differing heights to different experiments thing block, and simple structure is easy to operate；Rubber
The elastic reaction of layer 10 has cushioning effect, prevents experiment thing block from smashing operating board 1, improves the service life of the device；Handss
Stubborn bar 12 is easy to operate threaded rod 6.Therefore this freely lands motion test device of motion, can carry out identical height to different experiments thing block
Or the experiment with falling objects of differing heights, simple structure is easy to operate, long service life, with the very strong suitability, is adapted to big
Scale is promoted.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
Be appreciated that these embodiments can be carried out various changes in the case of without departing from principle of the present utility model and spirit, repair
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
