Abstract
The utility model discloses a kind of location articulated mounting, this device by being provided with the boss and groove of working in coordination in the pivot region of the first housing and the rotary axle box of the second housing, the binding face of boss and groove has at least one standstill face, the location realizing the first housing and the second housing is hinged, and coordinate location by friction mechanism, prevent from rotating, achieve the firm hinged location of the first housing and the second housing.The utility model can be used for the hinged of armrest and dinner table board.
Description
Technical field
The utility model relates to a kind of location articulated mounting, particularly, relates to the location articulated mounting of a kind of armrest and dinner table board.
Background technology
Common seat dining table plate and the connection of handrail, be normally provided with draw-in groove below dinner table board, connected and fixed, finish using at every turn, need to take off dinner table board, place separately by draw-in groove and two side handrails, very inconvenient.
Also there is people to improve this, design the dinner table board that can spin upside down around handrail, dig during use.As file CN203122810U discloses a kind of wheelchair dining table, comprise panel, loop bar, connecting rod, described loop bar is each on the side bar of described back side of panel and wheelchair installs one, and described connecting rod two ends are each passed through two described loop bars makes described panel be connected with wheelchair and spin upside down.This mode, although can realize spinning upside down of dinner table board, easily fixes loosely, slides.
Utility model content
The technical problems to be solved in the utility model is: the location realized between wheelchair dinner table board and handrail is hinged.
The solution that the utility model solves its technical problem is: provide a kind of location articulated mounting, comprise the first housing, second housing, jointed shaft, described first housing is provided with pivot region, described second housing is provided with rotary axle box, rotary axle box is positioned at pivot region and is connected with the first housing into rotation by jointed shaft, one end of described rotary axle box is provided with boss/groove, one end of described pivot region is provided with the groove/boss with described boss/groove fit, described boss has at least one and can to fit with groove, prevent the two standstill face in relative rotation, the axial width of described pivot region is greater than the axial width of described rotary axle box, the rotary axle box of the second housing can be slided in pivot region along jointed shaft, first housing, the rotation contact area of the second housing and jointed shaft is also provided with friction mechanism, be used for coordinating boss and groove to realize fixedlying positioning.Described boss and groove can be fit tightly, and also can be that part coordinates.
As the further improvement of technique scheme, described boss is wedge shape, is convenient to slip into location.
As the further improvement of technique scheme, described friction mechanism is a pin rod, and described jointed shaft is provided with locating hole, and described pin rod coordinates with locating hole through described rotary axle box, and preferably, described pin rod is threaded.
As the further improvement of technique scheme, described location articulated mounting also comprises a spring, and spring is positioned at pivot region, the below of jointed shaft.
The beneficial effects of the utility model are: the utility model by being provided with the boss and groove of working in coordination in the pivot region of the first housing and the rotary axle box of the second housing, the binding face of boss and groove has at least one standstill face, realize the hinged location of the first housing and the second housing, and coordinate location by friction mechanism, prevent from rotating, achieve the firm hinged location of the first housing and the second housing.The utility model can be used for the hinged of armrest and dinner table board.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, instead of whole embodiment, and those skilled in the art, under the prerequisite not paying creative work, can also obtain other designs and accompanying drawing according to these accompanying drawings.
Fig. 1 is the explosive view of location of the present utility model articulated mounting.
Detailed description of the invention
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.Obviously; described embodiment is a part of embodiment of the present utility model, instead of whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, all belong to the scope of the utility model protection.In addition, all connection/annexations mentioned in literary composition, not singly refer to that component directly connects, and refer to and according to concrete performance, can connect auxiliary by adding or reducing, and form more excellent draw bail.Each technical characteristic in the invention, can combination of interactions under the prerequisite of not conflicting conflict.
With reference to Fig. 1, a kind of location articulated mounting, comprise the first housing 1, second housing 2, jointed shaft 3, pin rod 4, spring 5, first housing 1 is provided with pivot region 11, second housing 2 is provided with rotary axle box 21, rotary axle box 21 is positioned at pivot region 11 and is rotationally connected by jointed shaft 3 and the first housing 1, one end of rotary axle box 21 is provided with boss 22, boss 22 is wedge shape, one end of pivot region 11 is provided with the groove 12 coordinated with boss 22, the axial width of pivot region 11 is greater than the axial width of described rotary axle box 21, second housing 2 can be slided in pivot region 11 along jointed shaft 3, jointed shaft 3 has locating hole 31, pin rod 4 is located through rotating shaft axle sleeve 21 and locating hole 31 friction fit, spring 5 is positioned at pivot region 11, the bottom of jointed shaft 3.
During use, first housing 1 is fixed on handrail, second housing 2 is fixed on dinner table board, and when dinner table board is dug, the rotary axle box 21 being positioned at pivot region 11 rotates around jointed shaft 3, when reach need angle time, be generally 90 °, the second housing 2 is slided along jointed shaft 3, make boss 22 snap in groove 12, pin rod 4 blocks locating hole 31, thus fixing dinner table board.Dinner table board packs up the not used time, and slide the second housing 2, and make pin rod 4 depart from locating hole 31, boss 22 departs from groove 12, rotates the second housing 2, thus pack up turning under dinner table board after arriving pivot region 11.
