Abstract
The utility model relates to a hinge, in particular to a gravity homing ball hinge, comprising a base and a rotatable end. The base comprises an axle hole. The rotatable end comprises a rotatable shaft. The rotatable shaft is inserted in the axle hole. A circular sliding bevel is arranged beside the rotatable shaft on the rotatable end. The two sides of the axle hole are provided with rollers for sliding the bevel. The gravity homing ball hinge can improve the friction matching between the original bevel and the bevel to the rolling matching between the bevel and the roller through the matching of the rollers arranged on the two sides of the axle hole and the sliding bevel on the rotatable end, thus greatly decreasing the friction force, avoiding the problem that the parts are easy to be damaged due to the long-term friction during the using process, improving the using stability of the products and prolonging the service life.
Description
Technical field
The utility model relates to a kind of hinge, especially a kind of gravity playback ball hinge.
Background technology
At present, partition door has used widely in the rest room of many public places.For the ease of installing, existing partition door uses gravity playback hinge usually, gravity playback hinge generally comprises a fixing base and a rotatable end, base and rotatable end are provided with the axle that cooperatively interacts and axis hole and round the circular gradient parts of axle or axis hole, when partition door was opened, the door body drove rotatable end and rises along gradient, when the door body is in free state, the door body is owing to the rotatable end of action of gravity compressing descends along gradient, thus the action that realization is closed the door.
But existing base and rotatable end all use the circular radian parts that match to carry out the realization that gravity playbacks, so two parts need long-term rubbing, so its durability can not get ensureing.
Summary of the invention
It is reliable that one of the purpose of this utility model provides a kind of use, durable gravity playback ball hinge.
To achieve these goals, the utility model adopts following technical scheme:
It comprises a base and a rotatable end, comprise an axis hole on the described base, rotatable end comprises a turning cylinder, and turning cylinder is inserted in the axis hole, the other sliding bevel that is provided with circle of turning cylinder on the rotatable end, its improvement is: be provided with the roller that slides for sliding bevel in the axis hole both sides.
Preferably, described sliding bevel be located at the concentric circular cylinder of turning cylinder on, sliding bevel comprises by this circular cylinder bottom surface diameter and cuts circular cylinder obliquely upward and two inclined-planes that form.
Preferably, described roller is located at the symmetric position of axis hole both sides.
Gravity playback ball hinge of the present utility model cooperates with the sliding bevel that turns on holding by the roller that is provided with in the axis hole both sides, original inclined-plane and frictional fit between the inclined-plane are improved to the inclined-plane to be cooperated with rolling between the roller, reduced frictional force greatly, avoided component in use owing to rub and flimsy problem for a long time, improve the stability that product uses, prolonged service time.
Description of drawings
Fig. 1 is the base end structural representation of the utility model first embodiment;
Fig. 2 is the rotatable end structure schematic diagram of the utility model first embodiment.。
The utility model purpose, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
The specific embodiment
As depicted in figs. 1 and 2, first embodiment of the present utility model comprises a base 1 and a rotatable end 2, comprise an axis hole 11 on the described base 1, rotatable end 2 comprises a turning cylinder 21, turning cylinder 21 is inserted in the axis hole 11, the turning cylinder 21 other sliding bevels 22 that are provided with circle on the rotatable end 2 are provided with the roller 12 that slides for sliding bevel in axis hole 11 both sides.
Described sliding bevel 22 be located at the concentric circular cylinder 23 of turning cylinder 21 on, sliding bevel 22 comprises by this circular cylinder 23 bottom surface diameters and cuts circular cylinder 23 obliquely upward and two inclined-planes that form.
In the present embodiment, described roller 12 is located at the symmetric position of axis hole 11 both sides.
The gravity playback hinge of present embodiment holds the sliding bevel 22 on 2 to cooperate by the roller 12 that axis hole 11 both sides at base 1 are provided with rotatable, original inclined-plane and frictional fit between the inclined-plane are improved to the inclined-plane to be cooperated with rolling between the roller, reduced frictional force greatly, avoided component in use owing to rub and flimsy problem for a long time, improve the stability that product uses, prolonged service time.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model manual and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
Claims (3)
