Referring to fig. 1-5, the invention provides a hand-clamping prevention sliding door, which comprises a door frame 1, a door plate 2, an air bag 3 and an inflating mechanism; the door plate 2 is horizontally and slidably arranged on the door frame 1, the air bag 3 is arranged on a first side wall 21 of the door plate 2 close to one side of the door frame 1, the inflating mechanism is provided with a first inlet and a first outlet, and the first outlet is communicated with the air bag 3; when the door panel 2 moves away from the door frame 1, the inflator mechanism absorbs gas from the outside through the first inlet; when the door panel 2 moves in a direction approaching the door frame 1, the inflator means inflates the airbag 3 through the first outlet.
In the specific working process of the hand-clamping prevention sliding door, when a user opens a door, namely the user pushes the door plate 2 to move in a direction far away from the door frame 1, the inflating mechanism absorbs gas from the outside through the first inlet, and a certain amount of air is stored in the inflating mechanism; when a user closes the door, namely the user pushes the door plate 2 to move towards the direction close to the door frame 1, the air stored in the air inflating mechanism inflates the air bag 3 through the first outlet; when door plant 2 drives 3 movements of gasbag to 3 times that lean on of gasbag by door frame 1, because 3 inside gassiness of gasbag, gasbag 3 is because of the continuous tympanites of gaseous increase, forms softer intermediary, even user's hand does not in time loosen, gasbag 3 also can play certain cushioning effect, avoids the first lateral wall 21 of door plant 2 and door frame 1 to take place direct collision and leads to user's hand to be hindered by the clamp.
In this embodiment, the anti-pinch sliding door that provides because 3 inside the user opens the door and the in-process of closing the door of gasbag is full of gas, gasbag 3 is because of the continuous tympanites of gaseous increase, forms softer intermediary, even user's hand does not in time loosen, gasbag 3 also can play certain cushioning effect, avoids the first lateral wall 21 of door plant 2 and door frame 1 to take place direct collision and leads to user's hand to be pinched.
When a user opens the door, the inflation mechanism automatically inhales and stores; when the user closes the door, the air inflation mechanism automatically inflates the air bag 3; the manual operation is not needed, and the use is simple and convenient;
the amount of gas to be replenished inside the airbag 3 does not change with the change in the speed at which the user pushes the door panel 2, and therefore, the safety factor is relatively high.
Referring to fig. 2-5, in a particular embodiment, the inflation mechanism includes a first check valve 4, a second check valve 5, a piston 6, and a cylinder 7;
the bottom of the door frame 1 is provided with a groove body 11, the cylinder 7 is arranged in the groove body 11, the piston 6 is hermetically arranged in the cylinder 7 and forms a cavity 71 with the interior of the cylinder 7, the piston horizontally slides in the cylinder 7 in a reciprocating manner, and the outer end of the piston 6 is fixedly connected with the door panel 2;
the first one-way valve 4 and the second one-way valve 5 are both arranged on the cylinder 7, a first inlet is positioned on the first one-way valve 4, and a first outlet is positioned on the second one-way valve 5; the first one-way valve 4 has a second outlet and the second one-way valve 5 has a second inlet, both of which are in communication with the chamber 71.
When a user opens the door, that is, when the user pushes the door plate 2 to move in a direction away from the door frame 1, the door plate 2 drives the piston 6 to move in a direction away from the first inlet, at this time, the volume inside the chamber 71 increases, the pressure inside the chamber 71 decreases, the pressure inside the chamber 71 is lower than the external pressure, air in the external environment sequentially enters the second outlet and the inside of the chamber 71 through the first inlet of the first check valve 4 under the action of air pressure difference, and the chamber 71 stores a certain amount of air;
when a user closes the door, that is, the user pushes the door plate 2 to move in a direction close to the door frame 1, the door plate 2 drives the piston 6 to move in a direction close to the first inlet, at this time, the volume inside the chamber 71 is reduced, the pressure inside the chamber 71 is increased, the pressure inside the chamber 71 is greater than the pressure inside the airbag 3, air stored in the chamber 71 sequentially enters the first outlet and the inside of the airbag 3 through the second inlet of the second one-way valve 5 under the action of air pressure difference, and the airbag 3 is continuously inflated due to the increase of the air.
Further, the airbag 3 is disposed at the same height as the door panel 2. So that the air bag 3 has a buffering effect in the height direction of the door panel 2, and the buffering effect is further improved.
Further, the side of the door frame 1 close to the airbag 3 has a second side wall 12, and the side of the airbag 3 close to the door frame 1 has a third side wall 31 matched with the second side wall 12; when the door panel 2 drives the airbag 3 to move until the airbag 3 abuts against the door frame 1, the second side wall 12 is seamlessly attached to the third side wall 31. After the user closes the door, the second lateral wall 12 of gasbag 3 and the inseparable seamless laminating of third lateral wall 31 of door frame 1 for gasbag 3 forms a sealing member, not only plays good syllable-dividing effect, can avoid the mosquito to get into in the clearance of door plant 2 and door frame 1 moreover, plays fine protection against insects effect.
Referring to fig. 1-2, further, the bladder 3 is provided with a pressure relief valve 8. When the pressure of the gas in the air bag 3 reaches the limit value, the pressure relief valve 8 is opened to reduce the air pressure, so that the automatic protection effect on the air bag 3 is achieved, and the service life of the air bag 3 is prolonged.
Referring to fig. 6, in other embodiments, the bottom of the door frame 1 is provided with a guide rail 9 which is matched with the door panel 2 to slide, the guide rail 9 is horizontally arranged, and the door panel 2 is slidably mounted on the guide rail 9. The guide 9 forms a guide and support for the door panel 2.
Further, the airbag 3 has a first bonding portion on a side close to the door panel 2, the first sidewall 21 has a second bonding portion, the first bonding portion and the second bonding portion are arranged correspondingly, and the airbag 3 is bonded on the first sidewall 21 through the matching connection of the first bonding portion and the second bonding portion. When the gasbag 3 is ageing or damaged, directly dismantle from door plant 2 through the separation of first bonding portion and second bonding portion, conveniently change and clearance.
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 the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
