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 called again hinge) to connect, hinge can make door and window and wall live the wall of cupboard realize hinged, facilitate level to or vertically to unlatching.And hinge arrangement is along vertical axes level to opening when rotation, although rotation vertically freely, running into some external force, or wind-force is while brushing, very easily door and window is shut automatically, thereby people is locked out or the person is caused and collided with.Our normally used hinge on door is by the unsettled door doorframe that is hinged on simultaneously, and door there will be unavoidably some distortion sagging after permanent folding like this.And traditional hinge arrangement lubrication system not conventionally, hinge usually there will be and weares and teares or corrosion after using a period of time like this, 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 the magnetic force hinge of determining positioning resistance in multiple angles to the rotary door structure of assembling.
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; In described firm banking, on the close outer wall position of cannelure, be evenly equipped with the outer magnetic patch of magnetic force sensing cannelure axis direction, described rotating seat is inner is equipped with the just interior magnetic patch to described outer magnetic patch of magnetic force direction near outer wall position, shown in the opposite face employing opposite pole of outer magnetic patch and interior magnetic patch; Described rotating seat is rotatable to be assemblied on the middle cylinder boss of described firm banking.
As preferably, between described rotating seat and the outer wall of described cannelure, be equipped with annular dismountable adjustable ring.
As preferably, described rotating seat is connected by bearing with described cylinder boss, and rotating seat horizontal positioned is equipped with liquid lubrication oil in described cannelure.
Beneficial effect of the present invention is: this magnetic force hinge is used for class part to carry out hinge-connection, 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.So just can realize by the rotatable assembling of the two hinge-connection of the shop front, the principle of inhaling mutually due to opposite pole, in the time that firm banking, the upper outside magnetic patch of rotating seat and interior magnetic patch are just in time relative, will produce larger suction, this suction will become resistance in the time reversing described rotating seat, makes rotating seat rest on certain angle.This hinge can prevent that door-plate is subject to less power and will automatically cuts out, and this resistance is magnetive attraction simultaneously, can not produce magnetic wearing and tearing, and 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; The interior outer magnetic patch 3 near being evenly equipped with magnetic force sensing cannelure 11 axis directions on the outer wall position of cannelure 11 of described firm banking 1, described rotating seat 2 is inner is equipped with the just interior magnetic patch 4 to described outer magnetic patch 3 of magnetic force direction near outer wall positions, shown in the opposite face employing opposite pole of outer magnetic patch 3 and interior magnetic patch 4; Described rotating seat 2 is rotatable to be assemblied on the middle cylinder boss 12 of described firm banking 1.
This magnetic force hinge is used for class part to carry out hinge-connection, 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.So just can realize by the rotatable assembling of the two hinge-connection of the shop front, the principle of inhaling mutually due to opposite pole, in the time that firm banking 1, the upper outside magnetic patch 3 of rotating seat 2 and interior magnetic patch 4 are just in time relative, will produce larger suction, this suction will become resistance in the time reversing described rotating seat 2, makes rotating seat 2 rest on certain angle.This hinge can prevent that door-plate 7 is subject to less power and will automatically cuts out, and this resistance is magnetive attraction simultaneously, can not produce magnetic wearing and tearing, and the service time of hinge is longer.
As depicted in figs. 1 and 2, between described rotating seat 2 and the outer wall of described cannelure 11, be equipped with annular dismountable adjustable ring 5.Described adjustable ring 5 is toroidal, can adopt elastic rubber material to make, and is directly enclosed within on the outer wall of described rotating seat 2.Magnetic force between the external magnetic patch 3 of described adjustable ring 5 and interior magnetic patch 4 just has certain inhibition, can reduce magnetic force between outer magnetic patch 3 and interior magnetic patch 4, can regulate the rotary resistance between firm banking 1, rotating seat 2 by the adjustable ring 5 of changing different-thickness like this, make this resistance an applicable size.
Described rotating seat 2 is connected by bearing 6 with described cylinder boss 12, and rotating seat 2 horizontal positioned are equipped with liquid lubrication oil in described cannelure 11.Add the wearing and tearing that liquid lubrication oil can reduce bearing 6 greatly, the application life of improving whole magnetic force hinge.
