Description

Technical Field

[0001] The utility model belongs to the field of visual teaching aids, and in particular relates to a reciprocating power supply visual teaching aid. Background Art

[0002] With the development of the economy, the education industry has also achieved great development and progress. The examination-oriented education that only pursues academic performance while ignoring the cultivation of students' hands-on ability and interests has gradually begun to fail to keep up with the trend of the times. In the process of teaching, teachers need to use teaching aids to increase students' interest in learning.

[0003] At present, existing teaching aids are often just some display devices with display functions, which cannot intuitively show the fun of applying knowledge. They still need to rely on teachers to make boring language descriptions and cannot arouse students' interest in learning.

[0004] Therefore, in view of the problem that the existing teaching aids cannot intuitively demonstrate the application of knowledge, the teaching process is often boring and tedious language description, and cannot arouse students' enthusiasm for learning, a reciprocating power supply visualization teaching aid is designed. The motion trajectory of the ball is displayed through the teaching aid, and the teacher's explanation is combined to arouse students' interest in learning. Utility Model Content

[0005] In order to overcome the problem that existing teaching aids cannot intuitively demonstrate the application of knowledge, the teaching process is boring and cannot arouse students' interest in learning.

[0006] The technical solution of the utility model is: a reciprocating power supply visualization teaching aid, including a supporting base, a No. 1 track, a lifting assembly, a driving assembly, and a falling assembly; the supporting base is fixedly connected to the No. 1 track, a lifting assembly for transporting a small ball from bottom to top is installed on the supporting base, a driving assembly is installed on the inner side of the supporting base, and a falling assembly for transporting a small ball from top to bottom is connected between the lifting assembly and the No. 1 track.

[0007] Preferably, a reciprocating power supply visualization teaching aid is designed, the process of the reciprocating motion of the ball is demonstrated, and students' interest in learning is aroused through the teacher's explanation. The driving component provides power to the lifting component to transport the ball from a low place to a high place, and then the falling component is used to transfer the ball from a high place to a low place through gravity, thereby demonstrating the reciprocating motion of the ball.

[0008] Preferably, the lifting assembly includes a lifting column and a threaded transport shaft; a transparent lifting column is installed on the support base and is located on the left side of track No. 1, a threaded transport shaft is arranged in the lifting column, and two slots are provided on the right side of the lifting column. The threaded transport shaft is driven to rotate by the lifting column, so that the ball produces relative movement along the spiral surface, thereby achieving the effect of transporting the ball from a low place to a high place.

[0009] Preferably, the lifting assembly also includes a baffle, a fixed ring, and a rotating shaft; a baffle is provided at the front end of the upper slot, the baffle is inclined from top to bottom, a fixed ring installed on the edge of the slot is provided on one side of the baffle, and a rotating shaft plugged into the inner side of the fixed ring is fixedly connected to one side of the baffle. When the threaded transport shaft rotates, the rotating threaded blades will squeeze the baffle, so that the baffle can rotate on the fixed ring through the rotating shaft. The baffle can play a limiting role to prevent the ball from rolling along the rotation direction of the threaded blades, but instead rolls into the No. 2 track.

[0010] Preferably, the lifting assembly also includes a limit plate; the limit plate is fixedly connected inside the lifting column, and a support track is connected between the limit plate and the slot located above; the limit plate and the inner wall of the lifting column will generate friction with the ball, thereby preventing the rolling ball from rolling off the blades of the threaded transport shaft during upward transportation; when the ball moves to the upper slot, it rolls along the support track into the No. 2 track under the limitation of the baffle.

[0011] Preferably, the driving assembly includes a variable speed motor, a reducer, and a knob; the variable speed motor is installed in the support base, the reducer with a transmission element connected to the threaded transport shaft is installed in the support base, the reducer is connected to the transmission element of the variable speed motor, and a button for turning on and off the variable speed motor and a knob for adjusting the speed of the variable speed motor are provided on the support base. The variable speed motor drives the threaded transport shaft to rotate, and the rotation speed of the threaded transport shaft can be changed by the knob, so as to carry out comparative experiments. When the number of small balls in the lifting column is too large, the required power becomes greater, and the reducer can reduce the transport pressure of the threaded transport shaft. The variable speed motor is powered by a battery, and the battery can be replaced and can be charged through a USB port opened on one side of the support base.

[0012] Preferably, the falling component includes track No. 2, pipes, and connecting pipes; track No. 2 is installed at the front end of the slot located above, and a falling channel composed of multiple pipes and connecting pipes is connected between track No. 2 and track No. 1. The lifting component transports the ball to track No. 2, and then enters the falling channel along track No. 2. The pipes in the falling channel are all tilted downward, and the ball is transported from a high place to a low place by its own gravity. Every two pipes are connected by a connecting pipe. The complexity and sophistication of the falling channel depends on the number of pipes and connecting pipes.

[0013] Preferably, a semi-arc baffle is installed between track No. 1 and the pipe, a partition is fixedly installed on the support base, small balls are placed in the support base, and the semi-arc baffle matches the diameter of the small balls to form a barrier to prevent the small balls from stacking up when there are too many small balls on track No. 1. The excess small balls are loaded into the support base for easy carrying.

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] See also Figure 1-6The utility model provides an embodiment: a reciprocating power supply visualization teaching aid includes a supporting base 1, a No. 1 track 2, a lifting component, a driving component, and a falling component; the supporting base 1 is fixedly connected to the No. 1 track 2, a lifting component for transporting a small ball from bottom to top is installed on the supporting base 1, a driving component is installed on the inner side of the supporting base 1, and a falling component for transporting the small ball from top to bottom is connected between the lifting component and the No. 1 track 2. By designing a reciprocating power supply visualization teaching aid, by demonstrating the process of the reciprocating motion of the small ball, cooperating with the teacher's explanation to arouse students' interest in learning, the driving component provides power for the lifting component, the small ball is transported from a low place to a high place, and then the falling component is used to realize the transfer of the small ball from a high place to a low place through gravity, thereby demonstrating the reciprocating motion of the small ball.

[0026] See also Figure 3-4 In this embodiment, the lifting assembly includes a lifting column 301 and a threaded transport shaft 302; a transparent lifting column 301 located on the left side of the No. 1 track 2 is installed on the support base 1, and a threaded transport shaft 302 is arranged in the lifting column 301. Two notches are provided on the right side of the lifting column 301, and the lifting assembly also includes a baffle 303, a fixing ring 304, and a rotating shaft 305; a baffle 303 is arranged at the front end of the notch located at the top, and the baffle 303 is inclined from top to bottom. A fixing ring 304 installed on the edge of the notch is arranged on one side of the baffle 303, and a rotating shaft 305 inserted into the inner side of the fixing ring 304 is fixedly connected to one side of the baffle 303. The lifting assembly also includes a limiting plate 306; a limiting plate 306 is fixedly connected in the lifting column 301, and a limiting plate 306 is connected between the limiting plate 306 and the notch located at the top. The support track drives the threaded transport shaft 302 to rotate through the lifting column 301, so that the small ball produces relative movement along the spiral surface, thereby realizing the effect of transporting the small ball from a low place to a high place. When the threaded transport shaft 302 rotates, the rotating threaded blades will squeeze the baffle 303, so that the baffle 303 can rotate on the fixing ring 304 through the rotating shaft 305. The baffle 303 can play a limiting role to prevent the small ball from rolling along the rotation direction of the threaded blades, but instead rolls into the second track 501. The limiting plate 306 and the inner wall of the lifting column 301 will generate friction with the small ball, which can prevent the small ball that can roll from rolling off the blades of the threaded transport shaft 302 during the upward transportation process. When the small ball moves to the upper notch, it rolls along the support track into the second track 501 under the limitation of the baffle 303.

[0027] See also Figure 2 , 56. In the present embodiment, the driving assembly comprises a variable speed motor 401, a reducer 402 and a knob 403; the variable speed motor 401 is installed in the supporting base 1, the reducer 402 whose transmission element is connected to the threaded transport shaft 302 is installed in the supporting base 1, the reducer 402 is connected to the transmission element of the variable speed motor 401, the supporting base 1 is provided with a button for switching the variable speed motor 401 and a knob 403 for adjusting the speed of the variable speed motor 401, the falling assembly comprises a No. 2 track 501, a pipe 502 and a connecting pipe 503; the No. 2 track 501 is installed at the front end of the slot located above, a falling channel composed of a plurality of pipes 502 and a connecting pipe 503 is connected between the No. 2 track 501 and the No. 1 track 2, a semi-arc baffle 6 is installed between the No. 1 track 2 and the pipe 502, the supporting base 1 is fixedly provided with a partition 7, a small ball is placed in the supporting base 1, and the rotation of the threaded transport shaft 302 can be changed by turning the knob 403. The moving speed can be used for comparative experiments. When the number of balls in the lifting column 301 is too large, the required power becomes larger. The reducer 402 can reduce the transportation pressure of the threaded transport shaft 302. The variable speed motor 401 is powered by a battery. The battery can be replaced and can also be charged through a USB interface opened on one side of the support base 1. The lifting component transports the balls to the second track 501, and then enters the falling channel along the second track 501. The pipes 502 in the falling channel are all tilted downward, and the effect of transporting the balls from a high place to a low place is achieved by the gravity of the balls themselves. Every two pipes 502 are connected by a connecting pipe 503. The complexity and exquisiteness of the falling channel depend on the number of pipes 502 and connecting pipes 503. The semi-arc baffle 6 matches the diameter of the balls and can form a barrier to prevent the balls from stacking when there are too many balls on the first track 2. The excess balls are loaded into the support base 1 for easy carrying.

[0028] When working, the teacher first puts the ball from the No. 1 pipe 502 into the slot below the lifting column 301, presses the button switch, and the variable speed motor 401 drives the threaded transport shaft 302 to rotate, so that the ball moves relative to the spiral surface. The ball is affected by the friction force of the inner wall of the lifting column 301 and the limit plate 306 and does not rotate with the spiral, thereby pushing the ball upward;

[0029] When the ball moves to the upper notch, it loses the blocking of the limit plate 306 and starts to roll along the rotation direction of the threaded blade. The baffle 303 plays a limiting role to prevent the ball from continuing to move along the rotation direction of the threaded blade. Instead, the ball rolls along the support track into the second track 501, then rolls along the drop track into the first track 2, and then rolls into the lifting column 301, realizing the circular motion of the ball.

[0030] The speed of the variable speed motor 401 can be adjusted by the knob 403, so that variable experiments can be carried out, which is convenient for teachers to explain. By opening the movable door, small balls can be taken out from the support base 1 and filled into the reciprocating power supply visualization teaching aid. The motor is started. Since too many small balls will require greater power, the torque is changed by the reducer 402 to reduce transportation pressure.

[0031] Through the above steps, a reciprocating power supply visualization teaching aid is designed. By intuitively displaying the motion trajectory of the ball and cooperating with the teacher's explanation, the relevant knowledge of physical laws and mechanical transmission can be intuitively demonstrated to students. At the same time, the reciprocating power supply visualization teaching aid has an interesting shape, which can arouse the learning interest of young students, drive the thinking of young students, and develop intelligence, so as to solve the problem that the existing teaching aids cannot intuitively display the application of knowledge, the teaching process is boring, and students cannot be interested in learning.
