Embodiment 1

[0028] Such as Figure 1-2 As shown, the anti-pinch double door structure of this embodiment includes a door frame 1, and two door panels 3 that are rotatably connected to the door frame 1 through door hinges 2, and the joints of the two door panels 3 are formed with mutual The matching splicing edge, wherein one side of the splicing edge is provided with an installation groove 4 on the board surface, and an airbag 5 is installed in the installation groove 4, and the airbag 5 is higher than the board surface of the door frame door panel 13 in the initial state Set, the airbag 5 is provided with a throttling port, when the door is closed, the door panel 3 on the opposite side of the airbag 5 presses the airbag 5 to shrink; when the door is opened, the door panel 3 releases the airbag 5 to make it shrink. its recovery.

[0029] Therefore, the anti-pinching double door structure of the present embodiment installs the air bag 5 on the splicing edge of the door panel 3, so that wh...

Embodiment 2

[0035] On the basis of the above-mentioned embodiment 1, the door frame 1 is provided with a protective plate groove 7 on the side connected to the door panel 3, and the position of the door panel 3 corresponding to the protective plate groove 7 is provided with an arc-shaped protective plate 8 , the opening and closing of the door panel 3 drives the arc-shaped guard plate 8 to be drawn out or inserted into the guard plate groove 7. Therefore, the anti-pinching double-leaf door structure of this embodiment avoids when the door panel 3 moves along the When the door hinge 2 rotates at a certain angle, there is a gap between the door panel 3 and the adjacent door frame 1, and the door is suddenly closed, and the human hand is too late to pull out the danger of being pinched. There is an arc guard plate 8 to cover the gap between the door panel 3 and the door frame 1, which can prevent hands from being placed between the door frame 1 and the side wall of the door panel 3, and furth...

Abstract

The invention provides a double-door structure with a hand clamping prevention function. The double-door structure comprises door frames and two door sheets rotatably connected on the door frames through door hinges, splicing edges matched with each other are formed at joints of the door sheets, the splicing edge on one side is provided with a mounting groove along the top side, an air bag is mounted in the mounting groove, the air bag in the initial state is arranged in a manner of being higher than the top sides of the door sheets, and a throttle opening is arranged in the air bag; when a door is closed, the door sheet on the opposite side of the air bag presses the air bag to retract, and when the door is opened, the air bag is released to reset by the door sheet. The air bag is mounted at the position where the door sheets are jointed, so that the door sheet can press on the air bag when the door is quickly closed by external force, air in the air bag cannot be discharged timely, elastic effect can be applied to the door sheets, quick closing of the door can be effectively buffered, accidental clamping of the hand too late to withdraw is prevented, and safety of living at home is improved.

Description

technical field [0001] The invention relates to a hand-pinch-proof double-leaf door structure, which belongs to the technical field of fixed buildings. Background technique [0002] In daily life, if people close the door with too much force, or if the hand of the person who closes the door is not retracted in time for reasons such as wind, it is easy to cause the hand to be pinched by the door, especially for children, this problem is more likely to occur. There have been organizations According to the survey, the probability of being pinched by the door in a home accident is as high as 35%. Therefore, the door with the anti-pinching function is particularly important to improve the safety of the home. [0003] Though there are many solutions for this problem in the prior art, its weak point is that design is too loaded down with trivial details, although perhaps door is blocked, but can't close tightly. Chinese patent document CN103352631A discloses an anti-pinch door fra...
