Anti-pinch door

Abstract

The invention provides an anti-pinch door. The anti-pinch door comprises a door frame, a door body and a fan-shaped rotating piece; a fixed shaft is rotationally connected to the position, close to acircle center, of the fan-shaped rotating piece, and the fixed shaft penetrates out of the upper end of the fan-shaped rotating piece to be fixedly connected with the door frame and / or penetrates outof the lower end of the fan-shaped rotating piece to be fixedly connected with the ground; the fan-shaped rotating piece comprises a first plane, a second plane and a first arc-shaped face; the firstplane is seamlessly and fixedly connected with the door body, the door frame is provided with a movable groove capable of allowing the fan-shaped rotating piece to rotate, the movable groove comprisesa first seam blocking part and a second seam blocking part, wherein the first seam blocking part is matched with the rotating track of the second plane and is arranged close to the second plane, andthe second seam blocking part is matched with the rotating track of the first arc-shaped face and is arranged close to the first arc-shaped face. According to the anti-pinch door, a gap between the door frame and the door body during movement is reduced or even eliminated through the fan-shaped rotating piece, so that fingers of a child cannot stretch into the gap between the door body and the door frame, and therefore, the clamping injury condition is prevented.

Description

technical field [0001] The invention relates to a door structure with improved safety performance. [0002] Specifically, it relates to anti-pinch doors. Background technique [0003] In daily life, closing the door carelessly, using too much force, or when closing the door due to wind and other reasons, it is too late to withdraw the hand, especially if there are children at home, it is easy to cause the hand to be pinched by the door. According to an agency survey, among all home accidents, the probability of being pinched by the door is as high as 35%. Therefore, doors with anti-pinching functions are particularly important for home safety. [0004] In the traditional door structure, the door body is generally installed with the door frame through hinges. Since the door body is usually set in a rectangular shape, when the door body rotates relative to the door frame through the hinge, there will be gaps between the front and rear sides of the door body and the door frame...

AI Technical Summary

Problems solved by technology

[0004] In the traditional door structure, the door body is generally installed with the door frame through hinges. Since the door body is usually set in a rectangular shape, when the door body rotates relative to the door frame through the hinge, there will be gaps between the front and rear sides of the door body and the door frame. And children will put their fingers into the gap to play out of curiosity, so when the door opens and closes, it will cause fingers to be pinched and so on.
