Description
Technical field
The utility model relates to a kind of electric extendable door, particularly a kind of electric expansion door hinge mechanism.
Background technology
Electric extendable door is a kind of by motor-driven, and with the novel gate that stretch mode is opened or closed, it is convenient, handsome in appearance that it opens and closes with it, many-sided advantage such as can electronicly control and has obtained increasingly extensive popularization and application.The basic structure of existing electric extendable door comprises head section and the retractable door body portion that is attached thereto, and wherein the retractable door body portion is formed with its transverse axis is hinged by two-layer vertical or horizontal staggered form connecting rod up and down by a plurality of doorframes, road wheel is housed bottom the doorframe.The vertical staggered form connecting rod of existing retractable door all is the interconnections in vertical plane, and the connecting rod overmatter can't be carried out ornamental design, thereby the structure dullness, and is ornamental all undesirable with aesthetic property; Though and horizontal staggered form connecting rod has provided a large amount of decoration spaces, structure really seems, and too swelling is assorted, and rigidity is relatively poor.
The utility model content
The utility model purpose is to provide a kind of electric expansion door hinge mechanism of simple in structure, good looking appearance.
To achieve these goals, the utility model adopts following technical scheme: a kind of electric expansion door hinge mechanism, comprise doorframe, and the doorframe downside is provided with the axle that is fixedly hinged, and upside is provided with can be along the slide hinged axle of doorframe slip; Downside is movably connected by the staggered form connecting rod between two doorframes, and adjacent staggered form link end is hinged, is hinged on the axle that is fixedly hinged of doorframe in the middle of the staggered form connecting rod; Upside flexibly connects by connecting rod between two doorframes, and an end of connecting rod is hinged on the slide hinged axle of doorframe, and the other end is hinged on the axle that is fixedly hinged of another one doorframe.
Described connecting rod and staggered form connecting rod can be straight-bars, also can be bows.
This electric expansion door hinge mechanism, simple in structure, novel, connect the be fixedly hinged linkage of retractable door of axle of the firm shared lower floor of upper strata hinge, effective memorandum space, the increase decoration space makes the retractable door moulding succinct, attractive in appearance.Lower floor's hinge zero slip point can effectively be eliminated operation shakiness and sliding friction that structure interval brings.This structure makes that the upper strata connecting rod is longer, improves the bulk strength of retractable door greatly, makes it more firm, not yielding dislocation between doorframe.The space that increases can make decorative effect perfect more, has more sight.

The specific embodiment
Embodiment: a kind of electric expansion door hinge mechanism shown in Fig. 1-4, comprise doorframe 1, doorframe 1 downside is provided with the axle 17 that is fixedly hinged, and upside is provided with can be along the slide hinged axle 16 of doorframe slip; Downside is movably connected by staggered form connecting rod 2 between two doorframes, and adjacent staggered form connecting rod 2 terminations are hinged, is hinged in the middle of the staggered form connecting rod 2 on the axle 17 that is fixedly hinged of doorframe; Upside flexibly connects by connecting rod 3 between two doorframes, and an end of connecting rod 3 is hinged on the slide hinged axle 16 of doorframe 1, and the other end is hinged on the axle 17 that is fixedly hinged of another one doorframe 1.
Each doorframe 1 of retractable door is flexibly connected by staggered form connecting rod 2 and connecting rod 3.Doorframe 1 comprises arc rhaeboscelia 11, munnion 12, upper transverse frame 13, lower transverse frame 14 and connecting bend 15, and upper transverse frame 13 and widen arc rhaeboscelia 11 makes retractable door whole updating grain husk, attractive in appearance, firm.Staggered form connecting rod 2 is for being the vertical placement moulding connecting rod of vertical intersection, and single-point is coupling and is fixed on the axle 17 that is fixedly hinged of doorframe in the middle of it.Connecting rod 3 has been the support moulding connecting rod of firm support effect, one end and the staggered form connecting rod 2 shared single-points axle 17 that is fixedly hinged, and the other end slides in adjacent doorframe 1 internal chute by slide hinged axle 16.Along with the unlatching of retractable door, staggered form connecting rod 2 formed decorations are just as the lotus of gradually opening, and are simple in structure and have a visual sense of beauty.
Connecting rod 3 and staggered form connecting rod 1 can be straight-bar, bow or moulding part, and the variation of its Any shape all falls into protection domain of the present utility model.
Claims (2)
1, a kind of electric expansion door hinge mechanism comprises doorframe, it is characterized in that: the doorframe downside is provided with the axle that is fixedly hinged, and upside is provided with can be along the slide hinged axle of doorframe slip; Downside is movably connected by the staggered form connecting rod between two doorframes, and adjacent staggered form link end is hinged, is hinged on the axle that is fixedly hinged of doorframe in the middle of the staggered form connecting rod; Upside flexibly connects by connecting rod between two doorframes, and an end of connecting rod is hinged on the slide hinged axle of doorframe, and the other end is hinged on the axle that is fixedly hinged of another one doorframe.
