Embodiment 1

[0026] like Figure 1-3 As shown, the anti-pinch sealed door structure of this embodiment includes a door frame 1, and a door panel 3 that is rotatably connected to one side of the door frame 1 through a door hinge 2, and the door frame 1 is arranged on a panel surface opposite to the door panel 3. There is an installation groove 4, and an airbag 5 is installed in the installation groove 4. The airbag 5 is set higher than the door frame 1 in the initial state, and a throttle is provided on the airbag 5. When the door is closed, the door panel 3 is pressed The airbag 5 makes it shrink; when the door is opened, the door panel 3 releases the airbag 5 to restore it.

[0027] Therefore, the anti-pinch airtight door structure of this embodiment installs the air bag 5 on the door frame 1, so that when the door is suddenly closed by an external force, the door panel 3 will press on the air bag 5, because the air bag 5 is provided with The gas in the airbag 5 cannot be released in tim...

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-pinch sealed door structure of this embodiment avoids the problem that the door panel 3 moves along the door in the prior art. When the hinge 2 rotates at a certain angle, there will be a gap between the door panel 3 and the adjacent door frame 1, and the door will be closed suddenly and the human hand will be caught in danger of being caught without time to pull it out. The plate 8 covers 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...

Abstract

The invention provides an anti-pinch airtight door structure. The anti-pinch airtight door structure comprises a door frame, and a door sheet rotatably connected to one side of the door frame by use of a door hinge, wherein a mounting groove is formed in the surface, opposite to the door sheet, of the door frame; an air bag is mounted in the mounting groove; the air bag in the initial state is higher than the door frame; an air outlet is formed in the air bag; when the door is closed, the air bag shrinks under the pressure of the door sheet; when the door is opened, the air bag rebounds after the door sheet leaves. The anti-pinch airtight door structure has the advantages that the air bag is mounted on the door frame, when the door is closed quickly under sudden external force, the door sheet is pressed on the air bag and the air bag is incapable of releasing air immediately, and therefore, an elastic force is applied to the door sheet so that the quick closing of the door is effectively buffered and a hand can be prevented from being pinched accidentally; as a result, the household safety is improved.

Description

technical field [0001] The invention relates to a hand-pinch-proof sealed 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 frame, w...
