Description
Technical field
Technical field of physical experiment is the utility model is related to, specially a kind of inertia experiment demonstration trolley.
Background technology
The usually not deep understanding of inertia of the middle school student to the object of physics teaching, it is used in order to allow students to fully understand
Property law typically pass through inertia experiment coordinate teaching.
The Chinese patent of Application No. 201220509171.3 discloses a kind of inertia demonstration trolley, and the utility model is square
The bottom four corners in car face are respectively equipped with wheel, are provided with support on the top in square car face, are provided with the top middle part of support
The cylinder of one upper and lower opening, a bottom cylinder is provided with square car face, the bottom cylinder is mutually vertical corresponding with cylinder, and hook is located at support
Side, one end of lifting rope is connected with small iron ball, and the other end is connected with hook, and small iron ball is suspended in cylinder.Pass through the above
Set, when the utility model can demonstrate object uniform motion in physics teaching, because inertia energy keeps original motion state,
Be advantageous to break through understanding of the Physics Learning middle school student to this concept of inertia.
But the utility model needs to cut lifting rope rapidly when it does linear uniform motion in operation, in actual experiment
It is difficult to operate, also, its linear uniform motion is not easy to be controlled, so it is difficult to the mesh for reaching teaching to a certain extent
, applicability and practicality are restricted to a certain extent.
Utility model content
The purpose of this utility model is to provide a kind of inertia experiment demonstration trolley, to solve to propose in above-mentioned background technology
Existing inertia experiment demonstration trolley exist in actual experiment poor controllability, be difficult to operation the problem of.
To achieve the above object, the utility model provides following technical scheme：A kind of inertia experiment demonstration trolley, including bottom
Seat, roller, hook, weight beam, connect cylinder, riser, support arm, electromagnet, wireless switching, remote control, battery, groove and iron
Ball, the bottom of the base are provided with roller, and the riser is fixedly installed in the top of base, and the support arm is fixedly installed in riser
Top side, the end of the support arm is provided with electromagnet, and the battery is located at the dorsal part of riser, the wireless switching and remote control it
Between carry out wireless connection.
Preferably, the connect cylinder vertically corresponds to electromagnet and set.
Preferably, the bottom of the electromagnet is provided with groove, and the iron ball is located in groove.
Preferably, the right-hand member of the base is provided with hook, and the hook is connected with weight beam.
Compared with prior art, the beneficial effects of the utility model are：The inertia experiment demonstration trolley is simple in construction, uses
Convenient and swift, compared to existing demonstration trolley, its is easy to operate, and dropping opportunity for iron ball, accuracy are controlled by remote control
Height, be advantageous to improve the effect of experiment, when can demonstrate object uniform motion, because inertia energy keeps original motion state, energy
The knowwhy of inertia in Students ' Learning physics is helped, the operation enthusiasm of mobilizing students, there is good practicality.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of inertia experiment demonstration trolley, including base
1st, roller 2, hook 3, weight beam 4, connect cylinder 5, riser 6, support arm 7, electromagnet 8, wireless switching 9, remote control 10, battery
11st, groove 12 and iron ball 13, the bottom of base 1 are provided with roller 2, and riser 6 is fixedly installed in the top of base 1, and support arm 7 fixes peace
Top side loaded on riser 6, the end of support arm 7 are provided with electromagnet 8, and battery 11 is located at the dorsal part of riser 6, wireless switching 9 and remote control
Wireless connection is carried out between device 10.
In above-described embodiment, specifically, connect cylinder 5 is vertically set corresponding to electromagnet 8, connect cylinder 5 is used to accept from electromagnet 8
On the iron ball 13. that drops
In above-described embodiment, specifically, the bottom of electromagnet 8 is provided with groove 12, iron ball 13 is located in groove 12, groove 12
Fitted with iron ball 13, make iron ball 13 be more easy to be adsorbed by electromagnet 8.
In above-described embodiment, specifically, the right-hand member of base 1 is provided with hook 3, hook 3 is connected with weight beam 4, made
