Door switch device

Abstract

The invention discloses a door switch device. The door switch device comprises a device main body, a speed regulating device disposed in the device main body and a locking device disposed in the device main body; the speed regulating device comprises a first cavity formed in the device main body, a first working block which can slide up and down is arranged in the first cavity, and first limitingslots which are communicated with each other are symmetrically formed in the inner walls of the left and right sides of the first cavity. At present, in some public places, many entrances and exits are provided with rotating doors, the rotation speed of most of the rotating doors cannot be adjusted according to the change of flow of people under normal circumstances, and the rotating doors need tobe pushed by human power for rotation and do not have locking functions. The designed door switch device aims at achieving the effects that the rotation speed of the door switch device can be increased to cope with the flow of people in a peak period when the flow of people is large, the door switch device can also be locked, and the functions of fire prevention and theft prevention when an emergency occurs can be achieved.
