Collision experiment demonstrator for teaching

The utility model relates to the field of teaching aids. The utility model relates to a collision experiment demonstrator for teaching. The device comprises a base, a photoelectric door, a translationcollision mechanism and a spring force application mechanism, the photoelectric door is arranged on the translation collision mechanism; the translation collision mechanism comprises a sliding table,two sliding rails and two sliding blocks; the two sliding rails of the same structure and size are symmetrically and fixedly arranged at the top of the sliding table in the horizontal direction of the sliding table. The spring force application mechanism is composed of a lifting support, a hinge plate and two sets of spring force application assemblies with the same size and structure. The two spring force application assemblies are symmetrically arranged on the two sides of the top end of the base. According to the utility model, the collision experiment can be displayed by manually liftingthe lifting support, the op
