Safe swing door

Abstract

A safe swing door comprises a framework and a door net. The framework is formed by welding circular pipes. A supporting framework is arranged in the middle of the framework. The door net is arranged on the supporting framework. Baffles are arranged on the upper side and the lower side of the supporting framework. A front baffle is arranged on the framework and arranged in the middle of the framework. A connecting rod is welded to the framework and provided with a connecting pipe. The connecting pipe is inserted in a spring device. Semi-rotation hinges are arranged on a fixed connecting rod and arranged at the upper end and the lower end of the fixed connecting rod. The lower end of the fixed connecting rod is fixed to the connecting rod through a self-locking nut. Due to the baffles, the safe door can be prevented from being stuck when used, and the safe door is more conveniently opened and closed; the spring device is arranged on the framework, and therefore the safe door can be automatically closed; the upper end of a hook clamps the connecting pipe, and therefore the safe door can be more firmly connected with the connecting pipe and is not prone to slipping off.

Description

technical field [0001] The invention relates to a safety device, in particular to a safety spring door. Background technique [0002] Safety has become a very important thing in building construction. Every building construction equipment needs to be focused on safety. Scaffolding is one of the most commonly used equipment in construction, and its safety performance also needs special attention. During the construction process In the face of different emergencies, it is often necessary to install safety doors in scaffolding. Such safety doors need to be opened and closed before construction workers put on the scaffold. Such safety doors need a lot of use during construction. At present, many safety doors require manpower to open and close. This opening and closing method leads to the safety performance of the safety door cannot be guaranteed, and due to the influence of wind force in the high altitude, when such a safety door is used in high altitude, it is often affected by...

[0002] Safety has become a very important thing in building construction. Every building construction equipment needs to be focused on safety. Scaffolding is one of the most commonly used equipment in construction, and its safety performance also needs special attention. During the construction process In the face of different emergencies, it is often necessary to install safety doors in scaffolding. Such safety doors need to be opened and closed before construction workers put on the scaffold. Such safety doors need a lot of use during construction. At present, many safety doors require manpower to open and close. This opening and closing method leads to the safety performance of the safety door cannot be guaranteed, and due to the influence of wind force in the high altitude, when such a safety door is used in high altitude, it is often affected by strong wind force, so that the safety door cannot pass through the construction personnel. Self-opening and closing, once the safety door cannot be opened and closed smoothly, the safety of the construction workers will be greatly challenged, and the construction workers may fall off the scaffold, causing casualties
