Abstract
The invention provides a positioning hinge which comprises a rotating shaft and a sleeve. The inner wall of the sleeve is matched with the rotating shaft, the rotating shaft is inserted in the sleeve, connecting lugs used for being connected with hinged devices are arranged on the rotating shaft and the sleeve, the side wall of the rotating shaft is provided with at least one positioning key capable of elastically contracting along the radial direction of the rotating shaft, and the inner wall of the sleeve is provided with key grooves allowing the positioning keys to be clamped in. The side wall of the rotating shaft is provided with containing grooves allowing the positioning keys to contact in, depth of each containing groove is larger than that of the corresponding positioning key, and an elastic member is arranged at the bottom of each positioning key. When the positioning keys on the rotating shaft align at the key grooves and are clamped in the same, a clamping structure is formed which stops the rotating shaft from continuing rotating, so that relative position between the rotating shaft and the sleeve is fixed. After the hinged devices relatively rotate by a certain angle, the clamping structure is formed inside the positioning hinge, in this way, even if external supporting force disappears, the hinged devices do not freely move relatively, so that effect of fixing the relative position between the hinged devices is realized, in other words, positioning effect is realized.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
See Fig. 1 and Fig. 2, embodiments provide a kind of locating hinge, comprise rotating shaft 1 and sleeve 2, the inwall of described sleeve 2 and described rotating shaft 1 adaptation, described rotating shaft 1 is inserted in described sleeve 2, described rotating shaft 1 with described sleeve 2 is equipped with for being connected the engaging lug (first engaging lug 11 and the second engaging lug 21) being hinged device, the sidewall of described rotating shaft 1 be provided with at least one can the positioning key 3 of radially elastic shrinkage, the inwall of described sleeve 2 is provided with the keyway 22 holding described positioning key 3 and snap in.When rotating shaft 1 relative sleeve 2 rotates, positioning key 3 is radially towards the central reduction of rotating shaft 1, when rotating shaft 1 turns an angle, positioning key 3 aligns with the keyway 22 of sleeve 2 inwall, positioning key 3 is moved in keyway 22 by elasticity, formed and obstruct rotating shaft 1 to continue the retaining structure rotated in sleeve 2, play locating effect.Engaging lug on locating hinge connects one group of hinged device of needs respectively, such as lamp housing and light cover (not shown), first engaging lug 11 is connected with light cover, second engaging lug 21 is connected with lamp housing, raise in the process of light cover in external force, rotating shaft 1 thereupon relative sleeve 2 is rotated, when positioning key 3 aligns with keyway 22 and snaps in wherein, rotating shaft 1 is subject to the resistance stopping that it is rotated further, and light cover can not be rotated further, and rests on and lamp housing shape state at angle, like this, even if the external force of cancelling, light cover also can not rotate automatically, plays the effect of location light cover.Now operating personnel are when operating lamp housing inside, and light cover would not cover automatically, weighs hand wounded.Certainly, the locating hinge that the embodiment of the present invention provides also not only is confined to the use of light fixture, and it also can be used on any device needing location hinged.
When positioning key 3 in rotating shaft 1 aligns with the keyway 22 in sleeve 2 and snaps in wherein, form retaining structure, this structure obstructs rotating shaft 1 to be rotated further, and secures the relative position between it and sleeve 2.Use after relatively rotating certain angle between the hinged device of the present invention, locating hinge inside forms above-mentioned retaining structure, like this, even if remove external bracing power, also can not be relatively freely movable between two devices, play the effect fixing relative position between two devices, i.e. positioning action.When positioning key 3 shrinks along the radial inward of rotating shaft 1, rotating shaft 1 can to continue sleeve 2 in rotation.Structure of the present invention is simple, good positioning effect, long service life and flexibly changing is movable and the state of location.
Further, the sidewall of described rotating shaft 1 is provided with the storage tank 12 holding the retraction of described positioning key 3, and the degree of depth of described storage tank 12 is greater than the thickness of described positioning key 3, and the bottom of described positioning key 3 is provided with elastic component.In rotating shaft 1 rotation process, when positioning key 3 does not align with keyway 22, positioning key 3 is contained in storage tank 12 completely, guarantees that rotating shaft 1 can be rotated swimmingly.When positioning key 3 aligns with keyway 22, elastic component provides outer power of moving for positioning key 3, makes it automatically to snap in keyway 22.
Particularly, the sidewall symmetry of described rotating shaft 1 is provided with two described positioning keys 3, and described elastic component is spring 4, and described rotating shaft 1 is provided with through hole 121, and described spring 4 is through described through hole 121 and two ends connect the bottom of positioning key 3 described in two respectively.Be appreciated that rotating shaft 1 often rotates 180 ° by figure, positioning key 3 just meets once with keyway 22, that is, uses between the hinged device of the present invention and often relatively rotates the effect that 180 ° just can occur a relative positioning.
As a kind of preferred embodiment of the present invention, described positioning key 3 is cambered surface with the fitting face of described sleeve 2 inwall.Cambered surface can make the easier slippage of positioning key 3 go out keyway 22, only need provide suitable external force rotating shaft 1, and positioning key 3 is extensible keyway 22 just, and retaining structure disappears, and rotating shaft 1 just can be rotated further.
Described rotating shaft 1 runs through described sleeve 2, and described rotating shaft 1 two ends are respectively equipped with the anticreep flange 13 and the anticreep securing member that prevent this rotating shaft 1 from departing from described sleeve 2, and the engaging lug (the first engaging lug 11) in described rotating shaft 1 and described anticreep flange 13 are positioned at same one end.
In embodiments of the present invention, described anticreep securing member is nut 5, and described nut 5 is locked in described rotating shaft 1 end.Like this, locating hinge would not lose efficacy because rotating shaft 1 and sleeve 2 are separated.
In order to reduce the friction between nut 5 and sleeve 2, between described sleeve 2 and described nut 5, be equipped with packing ring 6.
In embodiments of the present invention, described through hole 121 and described spring 4 are two, can avoid positioning key 3 that position occurs and depart from, and can make it stressed evenly.
It should be noted that, the quantity of positioning key 3 is not limited to two, and the sidewall of described rotating shaft 1 can be provided with multiple described positioning key 3,, and each described positioning key is uniformly distributed, the inwall of sleeve 2 is provided with the keyway 22 of respective amount, so, locating hinge can realize the location of multi-angle.
Except selecting spring 4, described elastic component also can be to be located in bottom described positioning key 3 and bottom described storage tank 12 between cushion, as long as the elastic force of reset can be provided for positioning key 3.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement or improvement etc., all should be included within protection scope of the present invention.
