Problems solved by technology
[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the Newton's pendulum in the prior art needs manpower to move and cannot start a large-scale Newton's pendulum, and solve the problem that people are easily hit by the ball after stirring the ball and cause safety accidents, thereby Provide a Newton's pendulum demonstration device with good safety performance without manpower toggling

Embodiment Construction
[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.
[0030] see Figure 1-4 , this embodiment provides a Newton's pendulum demonstration device, including a bracket 1 , a toggle mechanism 3 and a control mechanism 4 . A plurality of spheres 2 are arranged side by side on the support 1, and the spheres 2 can perform Newtonian pendulum motion under the action of an external force; the toggle mechanism 3 has a toggle member, and transmits the power of the power source to the The transmission mechanism of the toggle; the power source drives the toggle through the transmission mechanism to lift at least one sphere 2 to a certain height along the swing path, and then release the raised sphere 2 to hit the unraised sphere 2 ; The control mechanism 4 is used to control the number and height of the lifting mechanism 3 to lift the sphere.
[0031] Wherein, the toggle mechanism 3 has a su...

The invention provides a device for demonstrating a Newton cradle. The device includes a support, and a plurality of ball bodies which are arranged on the support side by side and can be affected by external force to perform Newton cradle motion; a poking mechanism having a poking piece, and transmission mechanism transmitting power of a power source to the poking piece, the power source driving the poking piece through the transmission mechanism to lift at least one ball body along a swing path to a certain height and loosening the lifted ball bodies to impact ball bodies that are not lifted; and a control mechanism used for controlling the number and height of the ball bodies lifted by the poking mechanism. The device for demonstrating the Newton cradle realizes swing control of the Newton cradle, does not need manpower to poke the ball bodies any longer, so the weight of the ball bodies can be heavy, and people can realize control of motion of the Newton cradle when away from a ball body swing area, thereby preventing the ball bodies from impacting an operator in operation, and improving safety.
Description
technical field [0001] The invention relates to the technical field of exhibition demonstration equipment, in particular to a Newton's pendulum demonstration device. Background technique [0002] Newton's pendulum is a demonstration device consisting of multiple spheres fixed in a row by slings. When one or more spheres on one side are lifted and released, the lifted spheres hit the unlifted sphere under the action of gravity. The sphere makes the same number of spheres on the other side pop up, and the popped sphere falls back and hits the sphere again, so that the sphere on one side is also ejected, and the spheres on both sides are ejected alternately and repeatedly, forming a Newtonian pendulum motion . [0003] In the existing Newton's pendulum, one or more spheres are manually moved, and the spheres are lifted and then released, so that the Newton's pendulum performs Newton's pendulum motion. However, this method of manual manipulation can only be applied to small Ne...
