Abstract
The utility model relates to a permanent magnet bidirectional automatic reset hinge, which comprises a shaft sleeve, the two ends of the shaft sleeve are provided with an upper end cover and a lower end cover, a magnetic rotation shaft is arranged in the shaft sleeve, the two ends of the magnetic rotation shaft are penetrated through the upper end cover and the lower end cover, the outer circle of the magnetic rotation shaft is covered with two semicircle tubular magnetic cores, the outer portions of the two semicircle tubular magnetic cores are provided with two semicircle tubular magnets, and 0.05-0.3mm gaps are arranged between the two semicircle tubular magnetic cores and the two semicircle tubular magnets. The two penetrating ends of the magnetic rotation shaft are connected with rotary wings, and an external connecting plate is connected on the axis direction of the shaft sleeve. The permanent magnet bidirectional automatic reset hinge has the advantages that the door panel can be opened in two directions rotating 180 degrees depended on the hinge which formed by the magnetic rotation shaft penetrating the shaft sleeve, through the character that the same poles of the magnets is repellent, and opposite poles are drawn, and has the function of automatic reset, which not only is suitable for door hinges, and door sliding-back devices of various doors, but also for various mechanical ways and product required to automatic open or close.
Description
Technical field
The utility model haberdashery and hardware product particularly relates to the two-way rotational automatic hinge that resets of a kind of permanent magnet.
Background technology
In the daily life, common door opening ways roughly can be divided into two big classes, and a kind of is the loose-leaf type structure, a kind of utilization roller and track mode are at most on the loose-leaf type utilization house door wherein, and existing loose-leaf type structure is used hinge, door-plate and doorframe are connected, door can be opened with rotation mode.Existing hinge arrangement through two symmetrical junction plate collocation are arranged, forms through pivot pin serial connection axle sleeve, needs during installation on door-plate and doorframe mating groove to be set, and makes the door-plate that hinge is installed carry out the door-plate switch with rotation mode.Though this kind flap is simple in structure, cheap, do not have auto-reset function.Another kind is that three gusset pieces are formed by connecting, make door have double-direction starting function, this kind reversible hinge is in order to allow door have the function of automatic involution, spring is arranged in the axle sleeve of junction plate, elastic force by spring makes door can recover the state of closing the door automatically, because the hinge inner spring is impacted easily, cause spring to produce the elastic fatigue phenomenon, make door to automatically reset.
Summary of the invention
The utility model provides a kind of characteristic of using magnet homopolar-repulsion and heteropole to inhale mutually for solving the technical problem that exists in the known technology, makes the two-way rotational automatic hinge that resets of permanent magnet of the owned automatic involution function of hinge.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the two-way rotational automatic hinge that resets of permanent magnet, it is characterized in that: comprise an axle sleeve, the axle sleeve two ends are fixed with upper end cover and bottom end cover respectively, in axle sleeve, be provided with its two ends and stretch out the magnetic rotating shaft of upper end cover and bottom end cover, magnetic rotating shaft cylindrical is coated with two semicircle tubulose magnetic cores, two halves pipe shape magnetic core outside is provided with two halves pipe shape magnet, magnetic rotating shaft two external parts are connected with the rotation wing, axle sleeve axially on be connected with outside link plate.
The utility model can also adopt following technical scheme:
The magnetic pole layout of two halves pipe shape magnetic core is: left semicircle tubulose magnetic core end and right semi-circle tubulose magnetic core end are heteropole.
The magnetic pole layout of two halves pipe shape magnet is: left semicircle tubulose magnet end and right semi-circle tubulose magnet end are heteropole.
The magnetic pole layout of left semicircle tubulose magnetic core end and left semicircle tubulose magnet end is a homopolarity.
Be provided with the gap of 0.05-0.3mm between described two halves pipe shape magnetic core and the two halves pipe shape magnet.
Advantage and the good effect that the utlity model has are: the utility model adopts in the axle sleeve magnetic rotating shaft that the axle sleeve end cap is stretched out at its two ends is set, magnetic rotating shaft cylindrical is coated with two semicircle tubulose magnetic cores, two halves pipe shape magnetic core outside is provided with two halves pipe shape magnet, magnetic rotating shaft two external parts are connected with the rotation wing, axle sleeve axially on be connected with the structure of outside link plate, connect axle sleeve by the magnetic rotating shaft and form hinge, and the characteristic of utilizing magnet homopolar-repulsion and heteropole to inhale mutually, to rotate the wing and outside link plate respectively fixedly on door-plate and the doorframe, and make the door-plate can be according to hinge Rotate 180 ° to opening and having an automatically reset function.Replace the existing spring mounting means that increases, reach the effect of closing the door automatically.The utility model is not only applicable to door hinge, various door bride visits her parents with her husband for the first time after the wedding device, and can be applicable to various mechanical systems and the product that need open automatically or close.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A-A sectional view of Fig. 1.
Among the figure: 1, axle sleeve; 2, upper end cover; 3, bottom end cover; 4, magnetic rotating shaft; 5, semicircle tubulose magnetic core; 6, semicircle tubulose magnet; 7, the rotation wing; 8, outside link plate.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-Fig. 3, the two-way rotational automatic hinge that resets of permanent magnet, comprise an axle sleeve 1, the axle sleeve two ends are fixed with upper end cover 2 and bottom end cover 3 respectively, in axle sleeve, be provided with its two ends and stretch out the magnetic rotating shaft 4 of upper end cover and bottom end cover, magnetic rotating shaft cylindrical is coated with two semicircle tubulose magnetic cores 5, the magnetic pole layout of semicircle tubulose magnetic core is: left semicircle tubulose magnetic core end and right semi-circle tubulose magnetic core end are heteropole, wherein, the upper end of left semicircle tubulose magnetic core is the N utmost point, the lower end is the S utmost point, and the upper end of right semi-circle tubulose magnetic core is the S utmost point, and the lower end is the N utmost point; The outside of two halves pipe shape magnetic core 5 is provided with two halves pipe shape magnet 6, and left semicircle tubulose magnet end and right semi-circle tubulose magnet end are heteropole, and promptly left semicircle tubulose magnet upper end is the N utmost point, and the lower end is the S utmost point, and right semi-circle tubulose magnet upper end is the S utmost point, and the lower end is the N utmost point; Left and right two halves pipe shape magnetic core end is a homopolarity with the corresponding magnetic pole layout in left and right two halves pipe shape magnet end.Be provided with the gap of 0.05-0.3mm between described two halves pipe shape magnetic core and the two halves pipe shape magnet.The characteristic that can utilize permanent magnet homopolar-repulsion and heteropole to inhale mutually makes the rotatable 180 ° of bidirectional openings of this magnet hinge, and possesses automatically reset function like this.Magnetic rotating shaft two external parts are fixedly connected with the rotation wing 7 respectively, axle sleeve axially on be connected with outside link plate 8, all be shaped on the hole that is used to install on the rotation wing and the outside link plate.
