Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes will be apparent to those skilled in the art as long as they are within the spirit and scope of the present invention as defined and defined by the appended claims, and all inventions contemplated by the present invention are protected.

As shown in fig. 1, 2 and 3, this magnetic door board boosting device includes magnetic stripe 5 by force of first magnetic stripe 3 by force and second, and magnetic stripe 5 is at same height by force of first magnetic stripe 3 by force and second, has guaranteed the maximize of effort between magnetic stripe 5 by force of first magnetic stripe 3 by force and second.

The first strong magnetic stripe 3 is fixedly arranged on the outer side of the fixed door panel 1 through the fixed bracket 2, and the second strong magnetic stripe 5 is fixedly arranged on a rotating device in the movable door panel 15; because first strong magnetic stripe 3 is located the outside of fixed door plant 1, the strong magnetic stripe 3 of second sets up inside movable door plant 15, makes the door normally closed, can not misplace or leave the clearance. The rotating device is connected with the handle on the movable door panel 15 through a power transmission device arranged inside the movable door panel 15. The handle is rotated to drive the rotating device to rotate, so that the polarity between the two first strong magnetic strips 3 and the second strong magnetic strip 5 is changed.

The rotating device comprises a second support 4 and a rotating block 6 which are fixedly installed inside the movable door panel 15, a second strong magnetic strip 5 is fixedly installed on the rotating block 6, the rotating block 6 is installed on the second support 4 through a rotating shaft, and a gear 7 is fixed at the end of the rotating block 6.

As shown in fig. 1, 4 and 5, the power transmission means includes a rack 8 installed inside the movable door panel 15 to be engaged with the gear 7, and the rack 8 is movable up and down in the vertical direction. The lower extreme of rack 8 is connected with the vertical movement portion that drives it and reciprocate, and vertical movement portion is connected with the handle that drives it and remove in vertical direction. The handle drives the rack 8 to move up and down through the vertical moving part, and the rack 8 is meshed with the gear 7 to drive the rotating block 6 to rotate.

The vertical moving part comprises a sliding groove 9 arranged inside the movable door plate 15 and a sliding block 10 arranged in the sliding groove 9, and the sliding block 10 moves left and right in the sliding groove 9. The sliding groove 9 is connected with the lower end of the rack 8, and the sliding block 10 is connected with the handle.

The handle comprises a handle 13 and a connecting rod 14, the handle 13 is arranged on a lock box 12 arranged at the lower end of the sliding chute 9 through a rotating shaft, one end of the connecting rod 14 is connected with the sliding block 10, and the other end of the connecting rod is connected with the handle 13. A spring 11 is also provided between the slide groove 9 and the lock case 12.

The magnetic door board boosting device provided by the scheme has the advantages that the using process is as follows:

when the fixed door panel 1 and the movable door panel 15 are in a closed state, the polarities of the first strong magnetic strip 3 and the second strong magnetic strip 5 are different, and attraction exists between the two magnetic strips. When the door needs to be opened, the handle 13 is rotated downwards, the handle 13 drives the slider 10 to move downwards and rightwards through the connecting rod 14, at the moment, the sliding chute 9 moves downwards vertically, and the spring 11 is compressed. The sliding groove 9 vertically moves downwards, meanwhile, the rack 8 is driven to vertically move downwards, the rack 8 is meshed with the gear 7, the gear 7 rotates to drive the rotating block 6 to rotate, so that the polarities of the first strong magnetic strip 3 and the second strong magnetic strip 5 are changed from different to the same, a repulsive force is generated, the moment of the door closer is offset, and the door is opened more easily.

After the process of opening the door is accomplished, under the moment effect that the door closer produced, movable door panel 15 can automatic closure, simultaneously because of the hand of people leaves handle 13, handle 13 has lost the effect of external force, and spring 11 begins the extension this moment, promotes the vertical rebound of spout 9 to drive rotatory piece 6 through gear 7 and rack 8 and rotate, make polarity change back mutually from the same between first strong magnetic stripe 3 and the strong magnetic stripe 5 of second, produce an appeal, make the door closed more fast.

To sum up, the utility model discloses simple structure, convenient to use through the polarity that changes between the strong magnetic stripe of first strong magnetic stripe and the strong magnetic stripe of second to produce a repulsion force or appeal, make the switch door become easier, reached laborsaving effect.
