Detailed Description
The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
Example 1
As shown in fig. 1-3, a buffer type magnetic door stopper comprises a first connecting plate 1 fixedly mounted on a door body and a second connecting plate 2 fixedly mounted on a wall body, wherein a cylinder 3 is fixedly connected to the side wall of the first connecting plate 1, a groove is formed in the end surface of the cylinder 3 far away from the first connecting plate 1, a permanent magnet rotating ring 4 is rotatably connected in the groove, a threaded hole is formed in the permanent magnet rotating ring 4 in a penetrating manner, a lead screw 5 is connected in the threaded hole in a threaded manner, a buffer block 6 is fixedly connected to one end of the lead screw 5 located outside the cylinder 3, a sealing plate 7 is fixedly connected to one end of the lead screw 5 located inside the cylinder 3, the sealing plate 7 is in sliding sealing connection with the inner side wall of the cylinder 3, a closed space 8 is formed between the side wall of the sealing plate 7 far away from the lead screw 5 and the cylinder 3, an annular buffer airbag 9 is; the side wall of the second connecting plate 2 is fixedly connected with a permanent magnet fixing ring 11, and it should be noted that the magnetic pole of the permanent magnet rotating ring 4 in the initial state is the same as that of the permanent magnet fixing ring 11.
When the door body is close to the wall surface, because the magnetic poles of the permanent magnet rotating ring 4 and the permanent magnet fixing ring 11 are the same, repulsion exists between the permanent magnet rotating ring 4 and the permanent magnet fixing ring 11, a primary buffering effect can be achieved, when the buffer block 6 is in contact with the second connecting plate 2, under the action of the reaction force of the second connecting plate 2, the lead screw 5 can be pushed to move towards the barrel 3, when the lead screw 5 moves, the permanent magnet rotating ring 4 can be driven to rotate, at the moment, the magnetic pole position of the permanent magnet rotating ring 4 changes, the repulsion between the permanent magnet rotating ring 4 and the permanent magnet fixing ring 11 gradually becomes smaller, and along with the continuous rotation of the permanent magnet rotating ring 4, suction is generated between the permanent magnet rotating ring 4 and the permanent magnet fixing ring 11;
meanwhile, the sealing plate 7 moves towards the cylinder 3, the volume of the closed space 8 gradually decreases, and the gas in the closed space is discharged into the annular buffering air bag 9 through the channel 10, so that the annular buffering air bag 9 expands, and the closer the permanent magnet rotating ring 4 and the permanent magnet fixing ring 11 are, the more obvious the expansion degree of the annular buffering air bag 9 is, and due to the existence of the annular buffering air bag 9, the impact between the permanent magnet rotating ring 4 and the permanent magnet fixing ring 11 can be effectively prevented, and the effect of buffering protection again is achieved.
Example 2
As shown in fig. 4 to 5, the present embodiment is different from embodiment 1 in that: be equipped with solid fixed ring 12 between permanent magnetism rotating ring 4 and the closing plate 7, gu fixed ring 12 and barrel 3's inside wall fixed connection, gu fixed ring 12 and the many flexible bellows 13 of fixedly connected with between the closing plate 7, flexible bellows 13 is flexible along its axis direction, lead screw 5 is the cavity setting, be equipped with the intercommunicating pore 14 that is used for communicateing flexible bellows 13 and lead screw 5 on the closing plate 7, buffer block 6 is the cover form setting, and is concrete, buffer block 6 adopts the elastic rubber material, and the inside of buffer block 6 is linked together with the one end that the closing plate 7 was kept away from to lead screw 5.
In this embodiment, when the sealing plate 7 moves toward the inside of the cylinder 3, the fixing ring 12 is fixed in position, so the bellows 13 is elongated, and the space formed by the bellows 13, the hollow screw rod 5 and the cover-shaped buffer block 6 is enlarged, and the air pressure is reduced, so that the buffer block 6 is tightly adsorbed on the second connecting plate 2 under the action of the external atmospheric pressure, and the adsorption effect of the door stopper is further improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
