Abstract
Physical experiments teaching aid, it includes wheel, fixed frame, hook, link block, the fixed frame is the cuboid frame shape of both ends open, and wheel is mounted on by pin joint mode in fixed frame, and wheel can rotate, there are two the link blocks, the top and bottom of fixed frame are separately fixed at, the link block of fixed frame one end is equipped with internal thread, and the link block of the other end is equipped with external screw thread, the lower end of the hook is equipped with internal thread or external screw thread, is connected on link block accordingly.The link block of the upper and lower side setting of the fixed frame of the utility model pulley, hook can be both installed, can also multiple wheels be connected to each other, combination that can be random, meet the needs of different experiments, it is easy for installation, also save spending, the bearing set in wheel can maximally reduce frictional force so that measurement data is more accurate.
Description
Technical field
The utility model is related to arrive physics teaching experiment appliance, it is specifically related to the physics for pulley Physical Experiment
Learn experiment teaching aid.
Background technology
Pulley theory is one of very important course in physics teaching, and general teacher is on textbook in explanation
Knowwhy told about, can not enable student is more vivid intuitively to understand the knowledge.There is application at present
In the teaching aid of pulley experiment, but the pulley of these teaching aids is all fixed structure, single-sheaved block and more pulleys, fixed pulley and moves cunning
Wheel etc. is all fixed, when carrying out single pulley, multigroup pulley when experiments, needs to install corresponding construction according to specific requirement
Pulley, this just needs to purchase a variety of pulleys so that the input of experiment teaching aid is larger, and flexibility is inadequate.Existing pulley experiment
Teaching aid frictional force is larger, influences DATA REASONING during experiment.
Invention content
The purpose of the utility model is to overcome above-mentioned technical deficiencies, provide a kind of reduction frictional force, can arbitrarily assemble
Physical experiments teaching aid.
To achieve the above object, the technical solution adopted in the utility model is：Physical experiments teaching aid, it include wheel,
Fixed frame, hook, link block, the fixed frame are the cuboid frame shape of both ends open, and wheel is installed by pin joint mode
In fixed frame, wheel can rotate, and there are two the link blocks, be separately fixed at the top and bottom of fixed frame, fixed frame
The link block of one end is equipped with internal thread, and the link block of the other end is equipped with external screw thread, and the lower end of the hook is equipped with interior spiral shell
Line or external screw thread, are connected on link block accordingly.
Further, fixing axle is equipped in the fixed frame, is equipped with bearing at wheel subcenter, fixing axle makes across bearing
Wheel is mounted in fixed frame.
Further, the rotor outer wall of the bearing is equipped with outer convex block, and outer convex block is inlaid on wheel, the axis
The stator inner wall held is equipped with interior convex block, and interior convex block is inlaid in fixing axle.
The beneficial effects of the utility model are：The link block of the upper and lower side setting of the fixed frame of pulley, can both install
Hook, can also multiple wheels be connected to each other, combination that can be random meets the needs of different experiments, easy for installation, also saves
Spending, the bearing set in wheel can maximally reduce frictional force so that measurement data is more accurate.

Specific embodiment
Physical experiments teaching aid as shown in Figure 1 and Figure 2, it includes wheel 1, fixed frame 2, hook 3, link block 4, described
Fixed frame 2 be both ends open cuboid frame shape, wheel 1 is mounted on by pin joint mode in fixed frame 2, and wheel 1 can be with
Rotation, there are two the link blocks 4, is separately fixed at the top and bottom of fixed frame 2, is set on the link block 4 of 2 one end of fixed frame
There is internal thread, the link block 4 of the other end is equipped with external screw thread 41, and the lower end of the hook 3 is equipped with internal thread or external screw thread, phase
That answers is connected on link block 4.
With reference to Fig. 1, as shown in figure 3, being equipped with fixing axle 21 in the fixed frame 2, be equipped with bearing 11 at 1 center of wheel,
Fixing axle 21 passes through bearing 11 that wheel 1 is made to be mounted in fixed frame 2.The rotor outer wall of the bearing 11 is equipped with outer convex block 111,
Outer convex block 111 is inlaid on wheel 1, and the stator inner wall of the bearing 11 is equipped with interior convex block 112, and interior convex block 112 is inlaid in solid
On dead axle 21.
As shown in figure 4, by the screw thread of the link block 4 on fixed frame 2, the connection of multiple pulleys can be realized, so as to real
Show a variety of arbitrary combinations, it is highly practical.
Claims (1)
