Problems solved by technology

[0003] Acceleration experiments are often done when studying physics. During the experiment, it is generally necessary to pull the car with hands and then release it. It requires the cooperation of multiple people to complete the experiment. In the second experiment, the car is also directly moved to the car by hand. Pull back, there may be a deviation of the track during the pull back process, which will affect the experimental results

Embodiment 1

[0023] see figure 1 , in the embodiment of the present invention, an environment-friendly and durable physical acceleration experiment device includes a substrate 1, a test bench 16, a weight 6, a traction rope 7, a trolley 12, a dotting timer 15 and a paper tape, and the bottom of the substrate 1 is four Supporting legs are installed on each corner, and rollers 21 are installed at the bottom of the supporting legs. The rollers 21 are self-locking rollers to facilitate the movement of the device. The top of the substrate 1 is provided with a test bench 16, and the dotting timer 15 is installed on the test bench. One side of the upper surface of 16, a paper tape is connected between the dot timer 15 and the trolley 12, the other side of the trolley 12 is connected with a traction rope 7, and the other end of the traction rope 7 passes through the fixed pulley 8 and is connected with the weight 6, and the fixed pulley 8 is installed on the end of the test bench 16 away from the ...

Embodiment 2

[0025] see figure 2 The difference between the embodiment of the present invention and embodiment 1 is that it also includes a blowing device, the blowing device includes a blower 23 and a nozzle 24, and the blower 23 is installed on the upper surface of the test bench 16 near the weight 6 At one end, the air outlet of the fan 23 is connected with the nozzle 24 through a trachea, and the nozzle 24 faces the test bench 16, and the fan 23 sucks in air and ejects it through the nozzle 24, so that dust or other impurities can be removed by blowing on the surface of the experiment bench 16, reducing the The resistance that dolly 12 advances, avoids influence experiment result.

[0026]The working principle of the present invention is: when the present invention is in use, start the first motor 2, the first motor 2 drives the two-way screw mandrel 3 to rotate, and the two-way screw mandrel 3 drives the two movable blocks 5 to approach or move away from each other, and the movable b...

Abstract

The invention discloses an environment-friendly durable physical acceleration experiment device, relates to the technical field of physical experiment equipment, and mainly aims to solve the problem that an existing experiment device needs a worker to pull a trolley with hands and needs cooperation of multiple persons. The device comprises a base plate, an experiment table, weights, a traction rope, a trolley, a dotting timer and a paper tape, and a first buffer device is arranged on one side, far away from the dotting timer, of the upper surface of the experiment table; motors are arranged onthe front side wall and the rear side wall of the trolley; a gear is mounted on an output shaft of the motor; electric push rods are mounted on front and rear sides of the upper surface of the experiment table; and racks are installed at the ends of telescopic rods of the electric push rods on the two sides of the experiment table and are meshed with the gear, and a second buffer device is arranged right under the weights. According to the present invention, with the arrangement of the motors, the gear, the rack and the electric push rods, the trolley does not need to always be pulled with the hand, and the influence on the experiment result due to the error caused by the manual pulling of the trolley by the experimenter is avoided.

Description

technical field [0001] The invention relates to the technical field of physical experiment equipment, in particular to an environment-friendly and durable physical acceleration experimental device. Background technique [0002] Experiment refers to one of the basic methods of scientific research. According to the purpose of scientific research, exclude external influences as much as possible, highlight the main factors and use some special instruments and equipment to artificially change, control or simulate the research object, so that certain things (or processes) occur or reproduce, so as to eliminate Understand natural phenomena, natural properties, and natural laws. [0003] Acceleration experiments are often done when studying physics. During the experiment, it is generally necessary to pull the car with hands and then release it. It requires the cooperation of multiple people to complete the experiment. In the second experiment, the car is also directly moved to the ...
