Infant safety door sill

Abstract

The invention discloses an infant safety door sill. The infant safety door sill comprises a doorframe, a door sill is hinged in the doorframe, at least one torsion spring return device is arranged between the right of the door sill and the doorframe, a movable rod capable of moving up and down is inserted in the left of the door sill, a zipper lifting rod device is arranged between the left upper part of the door sill and the doorframe, the zipper lifting rod device is connected with the top of the movable rod and enables the movable rod to move up and down, a locking device is arranged between the left middle part of the doorframe and the doorframe, and the locking device is opened and closed by up-and-down movement of an upright post on the movable rod. A handlebar push key and a joint chip are inserted into a card seat and a magnet seat respectively to realize the effect of dual protection. The design effectively improves the opening difficulty of the door sill, and limits the opening conditions of the safety door sill so that the safety door sill can reach the optimal safety protection effect.

Description

technical field [0001] The invention belongs to a safety gate, in particular to an infant safety gate with double-layer protection function and capable of automatic reset. Background technique [0002] At present, in order to prevent children from going in and out of specific places casually, people usually set a door frame bottom that can be closed on the door frame of the door, and have a safety gate of a certain height. [0003] Safety gates on the market now generally include two parts, a door frame and a gate fence. The gate fence is fixed on the gate frame by a door shaft, can rotate around the shaft, and is provided with a locking device, thereby realizing the functions of opening and closing the door. However, the general door rails cannot realize the automatic door closing function under the action of their own gravity. Therefore, in actual operation, it often happens that the user forgets to close the door or it is inconvenient to close the door with large items, m...

AI Technical Summary

Problems solved by technology

However, the general door rails cannot realize the automatic door closing function under the action of their own gravity. Therefore, in actual operation, it often happens that the user forgets to close the door or it is inconvenient to close the door with large items, making the setting of the safety door rail useless. It will also be impossible to achieve, and there is a great security risk

[0004] In addition, the general safety gate is locked by only one locking device, but when the child in the room is tall enough to touch and open the locking device, the locking relationship between the two doors can be released, thereby opening the safety gate and making the safety gate open. The safety gate loses its role in restricting children from entering and exiting specific places
