Detailed Description
As shown in fig. 1-4, fig. 1 is a schematic structural view of a door with finger protection function according to the present invention. Fig. 2 is a top view of the door with hands protected against being opened according to the present invention. Fig. 3 is a transverse sectional view of the door of the hand-pinching prevention room provided by the present invention when the door is opened. Fig. 4 is a partial sectional view of the door for preventing hand pinching when the door is opened according to the present invention.
Referring to fig. 1-4, the utility model provides a hand-clamping prevention door, which comprises a door frame 1, a rotating shaft 2, a stop block 3, a door plate 4 and an air bag 5; the door plate 4 is horizontally and rotatably mounted on the door frame 1 through the rotating shaft 2, the door plate 4 is coaxially and fixedly connected with the rotating shaft 2, a groove body 11 facing the rotating shaft 2 is formed in one side, close to the rotating shaft 2, of the door frame 1, the stop block 3 is coaxially and fixedly mounted on the rotating shaft 2 and can rotate in the groove body 11, the air bag 5 is arranged in the groove body 11, the air bag 5 is located in front of the stop block 3 in the rotating direction in which an included angle A between the door plate 4 and the door frame 1 is reduced, a throttling opening 51 is formed in the air bag 5, when the door is closed, the door plate 4 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the stop block 3 to press the air bag 5 to contract; when the door is opened, the stop 3 releases the air bag 5 to restore.
The prevent tong door of this embodiment is in specific working process, through being close to 2 one sides of pivot and offering the cell body 11 towards pivot 2 at door frame 1, install gasbag 5 in cell body 11, make when door plant 4 receives external force fast turn closure suddenly, contained angle A between door plant 4 and the door frame 1 reduces, door plant 4 rotates and drives dog 3 and press on gasbag 5, because be provided with throttle mouth 51 on the gasbag 5, gaseous unable timely release in the gasbag 5, therefore can exert the spring action to dog 3, make the fast turn of dog 3 obtain effectual buffering, further make pivot 2 drive door plant 4 slowly closed with door frame 1 under the cushioning effect of gasbag 5.
In this embodiment, the anti-pinch door that provides, when door plant 4 atress fast turn-round and door frame 1 closed, door plant 4 drives pivot 2, further drive dog 3 and press down gasbag 5, because of being provided with throttle mouthful 51 on the gasbag 5, gaseous unable timely release in the gasbag 5, therefore exert the spring action to dog 3, make the fast turn-round of dog 3 obtain effectual buffering, and then make pivot 2 drive door plant 4 slowly with door frame 1 closed under the cushioning effect of gasbag 5, prevent that the hand from not reaching to take out and being pressed from both sides the wound by accident, the security at home has been improved.
In the specific embodiment, the choke 51 is an air outlet provided on the airbag 5, the airbag 5 is further provided with an air inlet 52, and the caliber of the air outlet is smaller than that of the air inlet 52; therefore, when the door plate 4 is quickly closed with the door frame 1 to drive the stop block 3 to press the air bag 5, the air in the air bag 5 cannot be exhausted from the air outlet, so that the air bag 5 generates an elastic action on the door plate 4, and the impact of the door plate 4 is effectively relieved; when door plant 4 slowly closed, gas in the gasbag 5 can be discharged through the gas outlet for smooth closure of door plant 4, when door plant 4 opened, door plant 4 drove dog 3 and keeps away from gasbag 5 gradually, and the air can get into in the gasbag 5 through air inlet 52, and the bore of gas outlet is less than the bore of air inlet 52, makes the gasbag 5 of compression reply bloated state very fast, is convenient for reuse.
Furthermore, an adjusting valve 6 for adjusting the air output is arranged at the air outlet. Adjusting valve 6 is used for adjusting the size of air output, can control the switching condition of door according to actual demand, realizes preventing tong function. For example, when the door is used in summer in coastal areas, because extreme weather such as typhoon is frequent, the frequency of accidents of door clamping is high, the air output of the adjusting valve 6 is adjusted to be minimum, so that even in extreme weather such as typhoon, the door panel 4 can be effectively buffered and slowly closed under the mutual matching action of the air bag 5 and the stop block 3; when the room is stuffy and needs air flow exchange, but the room is completely open and the privacy life of an individual is influenced, the adjusting valve can be closed, and the gas in the air bag 5 cannot be discharged, so that the door plate 4 is in a half-open and half-closed state; when no people needing special care, such as infants, children and the like, exist in the room and the hand-clamping prevention function is not needed, the adjusting valve 6 is adjusted to the maximum, so that the air outlet is not smaller than the air inlet 52, and the door plate 4 is quickly closed with the door frame 1.
Further, the air bag 5 is arranged at the same height as the door panel 4, so that the air bag 5 has a cushioning effect in the height direction of the door panel 4, and the cushioning effect is further improved.
Further, in order to facilitate opening and closing of the door, the door further comprises a handle 7, and the handle 7 is fixedly installed on the door panel 4.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
