Abstract

The invention discloses a single-row amplitude experiment teaching device with a protection function, and belongs to the technical field of teaching aids. The single-row amplitude experiment teachingdevice with the protection function comprises a fixing block, a fixed pull rope, a film pressure sensor, a shell, a controller, a rotating mechanism and a limiting mechanism, a left side control circuit and a right side control circuit are connected in parallel so that the left side control circuit and the right side control circuit can independently control starting and stopping of an electromagnet, and the controller and a pressure sensitive switch are connected in series to prevent the limiting structure from mis-starting and affecting the experimental result. A plurality of limiting grooves are formed in the inner wall of a rope winding wheel, a first limiting rod and a second limiting rod control the rope winding wheel at the same time, it is guaranteed that when the rope winding wheel rotates, the first limiting rod and the second limiting rod can lock the rope winding wheel at any time, and inclined planes are arranged at the tail ends of the first limiting rod and the second limiting rod, so the anticlockwise rotation of the rope winding wheel is not limited, and the fixed pull rope is convenient to roll up.

Description

technical field [0001] The invention relates to the technical field of teaching aids, more specifically, to a single-row amplitude experimental teaching device with a protective function. Background technique [0002] The experimental teaching device refers to the device that causes the change of the experimental object under the condition of human control, and then observes, measures and analyzes the device. [0003] In the single pendulum amplitude experiment of chin head ball, the ball cannot be pushed when it is released, otherwise the ball will hit the chin, which poses a safety hazard. Contents of the invention [0004] 1. Technical solutions [0005] In order to solve the above problems, the present invention adopts the following technical solutions. [0006] A single-row amplitude experiment teaching device with protection function includes a fixed block, a fixed pull rope, a film pressure sensor, a casing, a controller, a rotating mechanism and a limit mechanis...
