Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflicting with each other.

A magnetic door-inhale device as shown in fig. 1-3, characterized in that: the swing limiting device comprises a telescopic door bolt piece 2 fixed on a door body 1, and a positioning piece 3 with magnetic force is arranged on a target surface, the door body 1 swings relative to a door frame and the positioning piece 3, the positioning piece 3 just faces to the radian stroke of the telescopic door bolt piece 2, and when the door body 1 swings to be positioned above the positioning piece 3, the telescopic door bolt piece 2 is adsorbed by magnetic force and relatively extends out of a butting positioning piece 3 to limit the swing of the door body 1.

Through the setting of above-mentioned scheme, setting element 3 and flexible keeper 2 set up independently, and setting element 3 hides at the target surface, can not occupy very big square influence outward appearance, and sets up the whole discovery of hiding of door stopper based on the structure, can not lead to the fact the influence to the outward appearance of the door body 1.

As a further arrangement of the above scheme, the retractable door bolt member 2 includes a main body 21, a retractable cavity 22 is provided in the main body 21, the retractable cavity 22 has a step surface 23, a retractable rod 24 extending from the main body 21 is provided in the retractable cavity 22, a return spring 25 for driving the retractable rod 24 to return and retract into the retractable cavity 22 is further provided between the retractable rod 24 and the step surface 23, the retractable rod 24 is divided into a rod body 242 and a rod head 241, and two ends of the return spring 25 abut against end surfaces of the rod head 241 and the step surface 23, respectively.

Through the arrangement of the scheme, after the telescopic rod 24 loses adsorption force, the reset spring 25 can drive the telescopic rod to be hidden in the door body 1 until the next adsorption force action, so that the telescopic rod 24 is prevented from being stretched out for a long time to rub with a target surface to generate scratches.

As a further arrangement of the above scheme, a buffer cushion block 28 is further disposed at an end of the telescopic rod 24 extending out relative to the main body 21, and the buffer cushion block 28 is disposed to prevent the telescopic metal rod 24 from being attracted and extending out rapidly to collide with the magnet block 33, which may cause abrasion, noise, etc.

As a further arrangement of the above scheme, the positioning member 3 includes a metal sheet 32 with a blocking lip edge 31, and further includes a magnet block 33 detachably connected to the metal sheet 32 by magnetic attraction, and it should be noted that the attraction between the magnet block 33 and the metal sheet 32 in the present application is necessarily greater than the attraction between the telescopic rod 24 and the magnet block 33, so as to prevent the telescopic rod 24 from reversely moving the door body after extending out and attracting the magnet block 33 to separate from the metal sheet 32.

Through above-mentioned scheme setting, at the normal state that opens and shuts, magnet piece 33 can form the absorption to telescopic link 24 to let telescopic link 24 with block lip limit 31 and form and block, the restriction door body 1 open and shut, and can dismantle the significance of connection design lies in, when not needing the door-inhale function or need open the door greatly, takes off magnet piece 33 and can relieve the door-inhale, very convenient.

As a further development of the above solution, said blocking lip 31 is fan-shaped and is located opposite the metal sheet 32 extending towards one end face of the telescopic door bolt 2.

As a further arrangement of the above scheme, a fixing glue 233 is disposed on one side of the metal sheet 32 facing the target surface to fix the metal sheet to the target surface, and the fixing glue 233 includes a 3M double-sided film.

As a further configuration of the above solution, the metal sheet 32 is provided with a screw hole 231, and the screw hole 231 is used for fixing the metal sheet 32 on the target surface by a screw.

The design principle of the utility model is as follows: punching a hole in a door body 1 in advance, installing and fixing a telescopic door bolt piece 2 into the door body 1, wherein a telescopic rod 24 faces one side of a target surface, a positioning piece 3 is arranged on the target surface of the door body 1 opposite to the telescopic door bolt piece 2 in a movable stroke, it is worth noting that a metal sheet 32 of the positioning piece 3 can be fixed with the target surface through 3M glue or screws, the metal sheet 32 can be freely arranged according to the required opening degree of the door body 1, the movable stroke opposite to the telescopic door bolt piece 2 is noticed, the positioning piece 3 can conveniently adsorb the telescopic rod 24, the metal sheet 32 fixes a cover and the magnet block 33 moves relatively, when the door body 1 is opened and closed above the positioning piece 3, the telescopic rod 24 is adsorbed by the magnet block 33 and extends out of butt joint, based on the arrangement of a blocking lip edge 31, the limiting door body 1 of the telescopic rod 24 can not swing continuously, the door body 1 swings reversely, the telescopic rod 24 is separated from adsorption, and is collected into the door body 1 based on a reset spring 25.

It is worth noting that the magnet piece 33 of the present utility model is movably arranged relative to the metal sheet 32, when not needed, the magnet piece 33 can be disassembled to remove the door stopper, and further based on the design of the door stopper can be removed in the present utility model, the present utility model can also be provided with a plurality of metal sheets 32 on the target surface, and the size of the opening degree of the door body 1 can be adjusted by switching the positions of the magnet piece 33 on the plurality of metal sheets 32, so as to satisfy the opening and closing problems of the door body 1 under different use states.

On the other hand, the implementation of a plurality of metal sheets 32 can also be realized, two metal sheets 32 are set as the relative blocking lip edges 31, one can block the maximum opening and closing angle of the door body 1, and the other can realize the effect that the door body 1 can not be closed after being opened, and can be applied to the use scenes such as normally open and half open.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
