[0029] Example 2
[0030] On the basis of the above-mentioned embodiment 1, the door frame 1 is provided with an installation groove 4 on the surface opposite to the door panel 3, and an airbag 5 is installed in the installation groove 4, and the airbag 5 is higher than the initial state. The door frame 1 is provided, and the airbag 5 is provided with a throttle. When the door is closed, the door panel 3 presses the airbag 5 to shrink it; when the door is opened, the door panel 3 releases the airbag 5 to restore it.
[0031] Therefore, in the anti-pinch hand-sealed door structure of this embodiment, the airbag 5 is installed on the door frame 1, so that when the door is suddenly closed quickly by external force, the door panel 3 will be pressed against the airbag 5, because the airbag 5 is provided with Throttle, the gas in the airbag 5 cannot be released in time, so it exerts an elastic effect on the door panel 3, so that the rapid closing of the door is effectively buffered, preventing the hand from being accidentally caught when it is too late to withdraw, and improving the safety of the home. Since the resilience of the airbag 5 used is very small, the phenomenon that the door is not closed tightly due to the resilience that occurs when a spring or other structure is adopted is avoided, and the door has good airtightness, simple structure, economical and practical, and good user experience.
[0032] It should be noted that the number of installation of the airbag 5 can be one or more, and the installation position is on the vertical door frame 1 that is the first to contact when the door panel 3 is closed. However, the installation form of the airbag 5 in this embodiment is not Limited to this, in another implementation form, the airbag 5 is installed on the door panel 3. When the door is closed, the door panel 3 drives the airbag 5 to press the door frame 1 to contract; when the door is opened, the door The door panel 3 is separated from the door frame 1, and the airbag 5 is released to restore it.
[0033] As an implementation with better effect, the throttle is an air outlet 5a provided on the airbag 5, and the airbag 5 is also provided with an air inlet 5b, and the air outlet 5a is smaller than the air inlet 5a. The air port 5b ensures that when the door panel 3 quickly closes and presses the airbag 5, because the air in the airbag 5 is too late to be discharged from the air outlet 5a, the airbag 5 exerts an elastic force on the door panel 3, thereby effectively alleviating the impact of the door panel 3. When the door panel 3 is slowly closed, the air in the airbag 5 can be discharged through the air outlet 5a, so that the door panel 3 is closed smoothly. When the door panel 3 is opened, air will enter the airbag 5 through the air inlet 5b. Moreover, the air outlet 5a is smaller than the air inlet 5b, so that the compressed airbag 5 can quickly return to the expanded state, which is convenient for reuse.
[0034] At the same time, the air outlet 5a is provided with an adjustment valve 5c for adjusting the amount of air output. The adjustment valve 5c is used to adjust the amount of air. The opening and closing conditions of the door can be controlled according to actual needs. For example, the adjustment valve 5c is adjusted When the door is quickly closed, it will rebound, and slowly close the air discharge of the airbag 5, so that the airbag 5 compresses the door to close, thereby realizing the anti-pinching function; or, the air outlet 5a is closed so that the door always has a door gap, which is convenient for some special situations. Ventilation and other requirements; or, increase the regulating valve 5c so that the air outlet 5a is not smaller than the air inlet 5b, the door panel 3 compresses the airbag 5, and the air in the airbag 5 can be quickly discharged through the air outlet 5a, which can also The door can be closed quickly. Therefore, the anti-pinching door of the present invention can be adjusted to a variety of use states, is flexible and reliable, meets the different needs of people's daily life, has strong practicability, and has a simple structure.
[0035] Further, part of the side surface of the airbag 5 protruding from the mounting groove 4 is attached to the panel surface of the door frame 1, and the airbag 5 side is supported by the panel surface of the door frame 1, so that it is not prone to shaking, and the fixing is more firm. And the anti-pinching performance is better.
[0036] In addition, a top block 6 is provided on the door panel 3 at a position corresponding to the airbag 5, and the door panel 3 is buckled to drive the top block 6 to press the airbag 5 and extend into the installation groove 4. Therefore, When the door is closed, the top block 6 will be inserted into the installation groove 4, so that the sealing performance of the door is better. The top block 6 can be made of rubber block or other materials, and its shape and size can be easily matched with the installation groove 4 The airbag 5 can be pressed, and the inner wall of the installation groove 4 can be fitted into the installation groove 4 to achieve sealing.
[0037] Specifically, the outer arc surface of the arc-shaped guard plate 8 is arranged tangentially to the surface of the door panel 3, which further ensures that when the door is opened, the connection between the door panel 3 and the door frame 1 is completely covered without leaving any Any gaps, to avoid the danger of being pinched by the hands too late, and the exterior effect is good, and the guard plate groove 7 penetrates the door frame 1 in the height direction, and the arc guard plate 8 and the door panel 3 The height of the door frame 1 and the door panel 3 is the same, so that the connection between the door frame 1 and the door panel 3 is sealed by the arc-shaped guard plate 8, to prevent wind from entering the room through the gap between the door panel 3 and the door frame 1, and the sealing effect of the door is better.
