Abstract

A safety spring door, which includes a door (1), a door frame (2), an electromagnet (3), a pressure sensor (4), a rotating shaft (5), a first spring (6), a nylon brush (7), a second Spring (8), controller (9), housing (10), the door (1) is hinged to the door frame (2) through the rotating shaft (5), and the outer walls of the upper and lower ends of the rotating shaft (5) are provided with first springs (6), one end of the first spring (6) is fixed on the door frame (2), and the other end is fixed on the door (1), and several pressure sensors (4) are arranged on the ground directly below the door (1) ), the present invention senses whether there is a user passing through the door frame through the pressure sensor, so that the door stops turning, effectively prevents the user from being hurt by the door, and improves the safety of the specific turning function door.

Description

technical field [0001] The invention relates to a door, in particular to a safety spring door. Background technique [0002] The general door is that the door frame and the door are connected by hinges, which can only be opened in one direction, and need to be closed manually after opening. In addition, due to the large gap between the door and the door frame, the sound insulation and heat insulation effect is relatively poor. [0003] Some existing spring doors such as the application number are a kind of spring door of 201220705455.X, which makes the door automatically close by the spring on the rotating shaft, but when the user passes through the door frame in turn, the rebounding door is easy to bruise the user. Contents of the invention [0004] The purpose of the present invention is to provide a safety spring door, which solves the problem of the existing spring door that the user is easily injured by the rebounding door when the user passes through the door frame o...
