Two guide wheel mounting grooves 22 are formed in the inner side of the upper end of the door body 2, and two guide wheels 23 are mounted in the guide wheel mounting grooves 22 to guide a pull rope 24.
The first spring 33 is a pull cord 24 spring and has a pretension force.
The second spring 9 is a compression spring and has a preload.
The specific working process is as follows:
the first implementation mode comprises the following steps: the structure as described above:
when the anti-pinch door designed by the invention is used, when the door body 2 is opened through the handle 3, the arc-shaped plate 4 slides outwards under the action of the first spring 33, the arc-shaped plate 4 slides to pull the sliding plate 7 to slide through the pull rope 24, after the door body 2 is opened for a certain angle, the trigger piece 31 arranged on the sliding plate 7 is separated from the elastic piece 32 arranged on the door body 2, then the door body 2 is continuously opened, after the arc-shaped plate 4 arranged in the door body 2 slides out to the limit state, the arc-shaped plate 4 stops sliding, and the sliding plate 7 also stops sliding; the anti-pinch bolt 8 is not triggered to extend out; after which the door body 2 can be continuously opened to a desired angle.
In the closing process, when the door body 2 is closed through the handle 3, after the door body is closed to a certain angle, the arc-shaped plate 4 is contacted with the door frame 1, the door frame 1 extrudes the arc-shaped plate 4 to work, so that the arc-shaped plate 4 retracts, the sliding plate 7 drives the sliding plate 7 to slide under the action of the reset spring 40, and the pull rope 24 between the sliding plate 7 and the arc-shaped plate 4 keeps a tensioned state; when the trigger piece 31 mounted on the slide plate 7 contacts the elastic piece 32 in the sliding process, the trigger piece 31 presses the elastic piece 32 to deform, and meanwhile, the door body 2 continues to be closed, and the anti-pinch bolt 8 is not triggered to extend in the process until the door body 2 is closed.
In the closing process, when the door body 2 is closed by holding the door edge of the door body 2 by fingers, electric quantity is suddenly reduced due to the fact that the two induction metal strips 13 installed on the door body 2 are in contact with the fingers, and signals of the sudden reduction of the electric quantity are transmitted to the control module; when the sliding plate 7 is in sliding process, after the triggering sheet 31 arranged on the sliding plate contacts the elastic sheet 32, the triggering sheet 31 extrudes the elastic sheet 32 to deform the elastic sheet, after the triggering sheet 31 contacts the elastic sheet 32, the control module obtains a contact signal, after the two signals simultaneously occur, the control module controls the electromagnetic push rod 28 to work, and the electromagnetic push rod 28 drives the limiting block 6 to retract to lose the limiting on the anti-pinch bolt 8; under the action of the second spring 9, the anti-pinch lock tongue 8 extends out; the effect of preventing the hands from being clamped is achieved through the protruding anti-clamping bolt 8. When the hand leaves the induction metal sheet, the electromagnetic push rod 28 works, the electromagnetic push rod 28 drives the limiting block 6 to extend out, and the anti-pinch bolt 8 retracts.
The first implementation mode comprises the following steps: the structure as described above:
when the anti-pinch door designed by the invention is used, when the door body 2 is opened through the handle 3, the arc-shaped plate 4 slides outwards under the action of the first spring 33, the arc-shaped plate 4 slides to pull the sliding plate 7 to slide through the pull rope 24, after the door body 2 is opened at a certain angle, the sliding plate 7 is in contact fit with the upper end of the anti-pinch bolt 8, then the door body 2 is continuously opened, after the arc-shaped plate 4 arranged in the door body 2 slides out to the limit state, the arc-shaped plate 4 stops sliding, and the sliding plate 7 also stops sliding; in this state, the anti-pinch bolt 8 is not triggered to extend; after which the door body 2 can be continuously opened to a desired angle.
In the closing process, when the door body 2 is closed through the handle 3, after the door body is closed to a certain angle, the arc-shaped plate 4 is contacted with the door frame 1, the door frame 1 extrudes the arc-shaped plate 4 to work, so that the arc-shaped plate 4 retracts, the sliding plate 7 drives the sliding plate 7 to slide under the action of the reset spring 40, and the pull rope 24 between the sliding plate 7 and the arc-shaped plate 4 keeps a tensioned state; in the process, the anti-pinch bolt 8 is not triggered to extend until the door body 2 is closed.
In the closing process, along with at arc 4 and door frame 1 contact back, door frame 1 extrusion arc 4 works for arc 4 contracts, and slide 7 drives slide 7 and slides under reset spring 40's effect, makes the stay cord 24 between slide 7 and the arc 4 keep taut state, along with closing of door body 2 promptly, slide 7 removes for preventing pressing from both sides spring bolt 8. When the door body 2 is held by fingers and the door edge of the door body 2 is closed, the electric quantity is suddenly reduced due to the fact that the two induction metal strips 13 arranged on the door body 2 are in contact with the fingers, and the signal of the sudden reduction of the electric quantity is transmitted to the control module, the electromagnetic push rod 28 is controlled to work through the control module, and the electromagnetic push rod 28 drives the limiting block 6 to retract to lose the limiting effect on the anti-pinch lock tongue 8; in the state, when the opening angle of the door body 2 is larger than 10 degrees, one end of the sliding plate 7 close to the arc-shaped plate 4 limits the upward movement of the anti-pinch bolt 8, and the anti-pinch bolt 8 cannot extend out; when the opening angle of the door body 2 is less than or equal to 10 degrees, one end of the sliding plate 7 close to the arc-shaped plate 4 does not limit the upward movement of the anti-pinch bolt 8, and the anti-pinch bolt 8 extends out under the action of the second spring 9; the effect of preventing the hands from being clamped is achieved through the protruding anti-clamping bolt 8.
Stay cord and slide hookup location avoid preventing pressing from both sides the movement track of spring bolt, realize the stay cord can not interfere with preventing pressing from both sides the spring bolt.
