This application has provided a new technical thought, and the anodal magnetism end of inhaling piece 401, the negative pole and inhaling piece 402 and female door and inhale 5 is neodymium iron boron magnet, and the appeal is extremely strong when female door inhale 5 and inhale piece 401 with the anodal when being close to, and wind-force blows and ordinary manpower mistake bumps 4 and female door inhales 5 disconnections when unable, has reduced the probability of opening by mistake of door.
The disconnection direction of the positive pole attraction block 401 with positive pole magnetism and the female door attraction 5 with negative pole magnetism is perpendicular to the magnetic induction line direction, the force required for disconnecting the pair of magnets perpendicular to the magnetic induction line direction is far smaller than the force required for disconnecting the pair of magnets along the magnetic induction line direction, and the human body work when an operator separates the sub door attraction 4 from the female door attraction 5 is reduced.
When the positive pole suction block 401 is adsorbed to the female door stopper 5, the handle 3 is rotated, the handle 3 drives the scroll spring 202 to rotate, the scroll spring 202 drives the male door stopper 4 to move upwards through the rope 6, the negative pole suction block 402 moves upwards and is close to the axis of the female door stopper 5, the negative pole suction block 402 and the female door stopper 5 with negative pole magnetism have a repulsion effect, when the negative pole suction block 402 gradually moves to a position above the axis of the female door stopper 5, the repulsion force of the negative pole suction block 401 to the female door stopper 5 is greater than the attraction force of the positive pole suction block 401 to the female door stopper 5, the male door stopper 4 and the female door stopper 5 are separated, an operator can keep the door away from the female door stopper 5 without pulling the door body 1 to close the door, and the work required by rotating the door body 1 when the operator closes the door is saved.
When the handle 3 is rotated, the first gear 203 is driven first, the first gear 203 drives the second gear 204, the second gear 204 is connected with the scroll spring 202, and because the diameter and the number of teeth of the first gear 203 are twice of those of the second gear 204, the rotating angle of the scroll spring 202 around the axis is twice of that of the handle 3, so that the angle of the handle 3 required by the operator to turn off the sub door stopper 4 and the main door stopper 5 is reduced, and the operation burden and the operation time of the operator are reduced.
The lower end of the sub door stopper 4 is fixedly connected with a spring 403, the upper end of the sub door stopper 4 is fixedly connected with a rigid rope 6, the upper end of the rope 6 is in contact with the periphery of the cam 205, when the upper end of the rope 6 is in contact with the periphery of the large end of the cam 205, the spring 403 is in a compressed state, the positive pole stopper 401 and the female door stopper 5 are located at the same height, the cam 205 is rotated by rotating the handle 3, the diameter of the periphery of the cam 205 in contact with the upper end of the rope 6 is gradually reduced, the rope 6 is pulled by the elastic force of the spring 403 to gradually move the sub door stopper 4 upwards, when the negative pole stopper 402 is pulled upwards to correspond to the female door stopper 5, the sub door stopper 4 and the female door stopper 5 repel each other and are disconnected, the door body 1 is closed, an operator only needs to rotate the cam 205 without overcoming the suction force between the sub door stopper 4 and the female door stopper 5, the sub door stopper 4 and the.
The end of the handle 3, which is far away from the handle shaft (303), can only rotate around the axis of the handle shaft (303) and close to the right end of the door body 1, so that when an operator rotates the handle 3, the interference of the handle 3 and mechanisms such as a lock head on the left side of the handle 3 is effectively avoided.
The foregoing is only a preferred embodiment of the present application; the scope of protection of the present application is not limited thereto. Any person skilled in the art should be able to cover all equivalent or changes within the technical scope of the present disclosure, which is equivalent to the technical solution and the improvement concept of the present disclosure, and the protection scope of the present disclosure.
