A kind of magnetic force hinge
Technical field
The present invention relates to hardware technical field, be specifically related to a kind of magnetic force hinge.
Background technology
Door or window usually use hinge (being also called hinge) to connect, and hinge can make the live wall of cupboard of door and window and wall realize hinged, facilitate level to or vertically to unlatching.And hinge arrangement is when rotating to unlatching along vertical axes level, although rotate freedom vertically, is running into some external force, or when wind-force brushes, very easily door and window is being shut automatically, thus people is being locked out or the person is caused and collide with.Our normally used hinge on door is hinged on doorframe by unsettled for door simultaneously, and such door there will be some distortion sagging unavoidably after permanent folding.And traditional hinge arrangement does not have lubrication system usually, such hinge usually there will be wearing and tearing or corrosion after used a period of time, affects hinged effect, or directly causes the damage of hinge.
Summary of the invention
For above problem, the invention provides a kind of magneticaction that uses and can provide to the rotary door structure of assembling the magnetic force hinge determining positioning resistance in multiple angle.
The technical solution adopted for the present invention to solve the technical problems is: this magnetic force hinge comprises firm banking, rotating seat; Described firm banking is flattened cylindrical shape, and its upper surface is designed with cannelure, and described rotating seat is toroidal; On the outer wall position of cannelure, the outer magnetic patch that magnetic force points to cannelure axis direction is evenly equipped with in described firm banking, described rotating seat is inner is equipped with magnetic force direction just to magnetic patch in described outer magnetic patch near outer wall position, and the opposite face of shown outer magnetic patch and interior magnetic patch adopts opposite pole; On the rotatable cylinder boss be assemblied in the middle of described firm banking of described rotating seat.
As preferably, between the outer wall of described rotating seat and described cannelure, be equipped with annular dismountable adjustable ring.
As preferably, described rotating seat is connected by bearing with described cylinder boss, rotating seat horizontal positioned, and described cannelure is built with the lubrication oil of liquid state.
Beneficial effect of the present invention is: this magnetic force hinge is used for carrying out hinge-connection to class part, and described firm banking can be used for being fixed with ground, and described rotating seat can be used for fixing with the axis of rotation of door-plate.The hinge-connection of the shop front so just can be realized by the rotatable assembling of the two, due to the principle that opposite pole is attracting, when firm banking, the upper outside magnetic patch of rotating seat and interior magnetic patch are just in time relative, larger suction will be produced, this suction will become resistance when reversing described rotating seat, makes rotating seat rest on certain angle.This hinge can prevent from door-plate to be subject to less power will automatically closing, and this resistance is magnetive attraction simultaneously, and can not produce magnetic wearing and tearing, the service time of hinge is longer.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described:
As shown in embodiment in Fig. 1 and Fig. 2, this magnetic force hinge, it comprises firm banking 1, rotating seat 2; Described firm banking 1 is flattened cylindrical shape, and its upper surface is designed with cannelure 11, and described rotating seat 2 is toroidal; On the outer wall position of cannelure 11, the outer magnetic patch 3 that magnetic force points to cannelure 11 axis direction is evenly equipped with in described firm banking 1, described rotating seat 2 is inner is equipped with magnetic force direction just to magnetic patch 4 in described outer magnetic patch 3 near outer wall position, and shown outer magnetic patch 3 adopts opposite pole with the opposite face of interior magnetic patch 4; On the rotatable cylinder boss 12 be assemblied in the middle of described firm banking 1 of described rotating seat 2.
This magnetic force hinge is used for carrying out hinge-connection to class part, and it specifically assembles mode as shown in Figure 3, and described firm banking 1 can be used for being fixed with ground, and described rotating seat 2 can be used for fixing with the axis of rotation of door-plate 7.The hinge-connection of the shop front so just can be realized by the rotatable assembling of the two, due to the principle that opposite pole is attracting, when firm banking 1, the upper outside magnetic patch of rotating seat 23 and interior magnetic patch 4 are just in time relative, larger suction will be produced, this suction will become resistance when reversing described rotating seat 2, makes rotating seat 2 rest on certain angle.This hinge can prevent from door-plate 7 to be subject to less power will automatically closing, and this resistance is magnetive attraction simultaneously, and can not produce magnetic wearing and tearing, the service time of hinge is longer.
As depicted in figs. 1 and 2, annular dismountable adjustable ring 5 is equipped with between described rotating seat 2 and the outer wall of described cannelure 11.Described adjustable ring 5 is toroidal, and elastic rubber material can be adopted to make, and is directly enclosed within the outer wall of described rotating seat 2.The magnetic force of described adjustable ring 5 externally between magnetic patch 3 and interior magnetic patch 4 just has certain inhibition, magnetic force between outer magnetic patch 3 and interior magnetic patch 4 can be reduced, rotary resistance between firm banking 1, rotating seat 2 can be regulated by changing the adjustable ring 5 of different-thickness like this, making this resistance an applicable size.
Described rotating seat 2 is connected by bearing 6 with described cylinder boss 12, rotating seat 2 horizontal positioned, and described cannelure 11 is built with the lubrication oil of liquid state.Add the wearing and tearing that liquid lubricant can reduce bearing 6 greatly, improve the application life of whole magnetic force hinge.
