Problems solved by technology

Therefore, the disadvantage of this type of door and window protection device is that once the door or window is picked or opened by a key, the intruder can break the door protection device or eject the mounting screw by cutting or violent destruction, thereby rendering the door protection device ineffective.
At the same time, the existing door protection devices generally need to be fixed on the door, window or the matching parts of the door and window or on the wall, so detachable or movable safety protection cannot be realized.

Abstract

The invention discloses a safety protection device of a portable door and a use method of the safety protection device. The safety protection device of the portable door comprises a bracket, a bend support arm and a support device, wherein the underside of the bracket is pasted to the door plate, the bracket comprises an outward extending plate inserted in the gap between the lower side of the door plate and the ground, the bracket comprises a trapezoid-shaped groove jointed with the upper end of the bend support arm, the support arm can swing up and down around the shaft, the lower end of the bend support arm is mounted on the support device composed of a support and an adjustable wrench; the square hole of the adjustable wrench sleeves outside the support square shaft, the adjustable wrench is rotated for screwing the support into the built-in thread of the bend support arm, or the thread shaft of the bend support arm is screwed into the built-in thread of the upper end of the support, so that the bend support arm and the support are mounted, and the size and strength of the tightening support force to the door plate can be changed by changing the screwing length. The portable, detachable, removable safety protection device suitable for various occasions as home and travel is provided, and the safety protection function is guaranteed.

Description

technical field [0001] The invention relates to the field of door and window safety protection, in particular to a portable door safety protection device and a use method thereof. Background technique [0002] At present, bolts, mortise locks and protective chains, swing rods or other swing structures are usually used in China as protective devices in the closed state of doors and windows. The use of this type of safety protection device requires the occupant to strengthen the protective effect by locking the door and window after closing, or requires the occupant to leave a small gap while opening the door and window, and the occupant must pass through the reserved gap to carry out Chat or view and receive items. Therefore, the shortcoming of this type of door and window guard is that once the door or window is picked or opened by a key, an intruder can break the door guard or pop out the mounting screws by cutting or violently destroying the door guard to make the door gu...
