Abstract

The invention discloses a photoelectric door of a multi-door structure. The photoelectric door comprises a base. The outer side wall of the base is fixedly connected with a fixing mechanism. A movableblock is arranged on the top of the base. A movement groove corresponding to the movable block is formed in the top of the base. The base is connected with the movable block through a regulation mechanism. The top of the base is connected with a bottom plate in a rotating manner. The top of the base is fixedly connected with an arc-shaped angle scale rod. Firstly, stability of the base is ensuredthrough the effect of the fixing mechanism; then, by means of the cooperation effect of the regulation mechanism and a limiting mechanism, the position of the movable block can be regulated and the movable block can be stabilized; and in this way, the angle between the bottom plate and the base is regulated through a regulation rod along with movement of the movable block. In the angle regulationprocess, people can observe angle changes through the arc-shaped angle scale rod, the movable block is limited after a certain angle is achieved through regulation, and therefore stability of the bottom plate is ensured and the downward sliding acceleration of objects at any angle can be conveniently detected.

Description

technical field [0001] The invention relates to the technical field of speed measuring equipment, in particular to a photoelectric gate with a multi-gate structure. Background technique [0002] The photogate is a device for counting, timing, and speed measurement. People can record the time interval by recording the shadow of the object blocking the photogate through the photogate. However, at present, the photogate cannot adjust the deflection angle of the photogate when it is in use, so it can only be used horizontally or vertically, which will affect the use of researchers. For example, people are studying the downward movement of an object at a specific angle due to gravity. Gravitational acceleration, so people can not adjust the angle of use of the photogate and affect people's research problems. [0003] To this end, we designed a photogate with a multi-gate structure. Contents of the invention [0004] The purpose of the present invention is to solve the problem...
