Door and safety door control system based on rotation lock control

Abstract

The invention discloses a door and safety door control system based on rotation locking control, which comprises a rotation angle locking mechanism (3), and the rotation angle locking mechanism (3) is provided with a door leaf movement following assembly (3a) and a door frame / Wall fixing assembly (3b). When the door lock function is activated, the door can be fixed at any angle when the door is opened at that angle without being pushed by external force. When the door lock function is turned off, the door can move freely, and the door leaf can be rotated and locked The system is automatically controlled so that children cannot switch on and off at will.

Description

technical field [0001] The invention relates to the technical field of door opening and closing control, in particular to a door and safety door control system based on rotation locking control. Background technique [0002] Doors are very common in daily life. They are mainly used to isolate spaces, and at the same time, they can be opened and closed freely to allow people to pass through. However, it is difficult to fix at the current opening and closing angle and resist a certain external force when it is not closed tightly or fully opened. For example, when there is a strong wind, the door that is not closed tightly will often be blown by the wind or open and close back and forth. When the door is not closed, you can only find something to prevent the door from being blown. If someone forgets to bring the key when going out temporarily, the door is closed by the wind. , it can only be reopened by picking the lock, and the door lock has to be replaced again, or when the ...

Problems solved by technology

[0002] Doors are very common in daily life. They are mainly used to isolate spaces, and at the same time, they can be opened and closed freely to allow people to pass through. The maximum angle limit, but it is difficult to fix at the current opening and closing angle and resist a certain external force when it is not closed tightly or fully opened

For example, when there is a strong wind, the door that is not closed tightly will often be blown by the wind or open and close back and forth. When the door is not closed, you can only find something to prevent the door from being blown. If someone forgets to bring the key when going out temporarily, the door is closed by the wind , it can only be reopened by picking the lock, and the door lock has to be replaced again, or when the child is playing, the door is shaken by the child. In addition to affecting the service life of the door, it is easy to close the door by mistake, and adults cannot Discover child safety inside the door

[0003] Defects of existing technology: lack of a mechanism that can fix the door at any opening angle, so that the door can be fixed at the corresponding angle, and it is not easy to be pushed by external force
