Description

Electronic four fan folding doors

Technical field

The utility model relates to the folding door field, especially a kind of motor-driven folding door.

Background technology

Occasions such as villa, garden, factory building in modern times, the use case of four fan folding gates is visible everywhere.Compare with two traditional fan folding gates, four fan folding gates make the folding spatial dimension at gate enlarge at double, required expansion space, back is opened at the gate but reduce relatively.Yet the modern life is to the deducted a percentage requirement of automation of the folding at gate, and the uncertainty of two-door movement locus in the four fan folding gates, give four fan folding gates motorized higher requirement has been proposed.In existing patent; Retrieve the patent No. and be " 200820093554.0 "; Name is called " slideway guiding motor-driven folding door ", a kind of motor-driven folding door under the slideway guiding is provided, simultaneously; Through the one type of special slideway that provides, can effectively solve the technical barrier of folding door no dead point operation under power drive.Yet, in practical application, drive the dead point and adopt the particular curve track for overcoming, exist track and make realistic problems such as difficulty, site operation inconvenience, simultaneously, described track very easily ponding, accumulation profile, inconvenience is open to traffic, not use problem such as easy to clean.

Summary of the invention

For curve track manufacturing, the site operation difficulty that overcomes existing motor-driven folding door; Rectilinear orbit is prone to the problem at power drive dead angle, the utility model provide a kind of trackless, avoid occurring power drive dead angle, simple in structure, the electronic four fan folding doors of being convenient to construction maintenance.

The utility model solves the technical scheme that its technical problem adopted:

A kind of electronic four fan folding doors; The both sides of said motor-driven folding door are furnished with a fan outer door and a fan inner door respectively; Be fixedly connected with first door-hinge on the said inner door, said first door-hinge is linked on the door-hinge seat rotationally, and said door-hinge seat is fixed on the support column; Be fixedly connected with second door-hinge on the said outer door, said second door-hinge is linked on the inner door and can rotates; Said motor-driven folding door also comprises folding transmission mechanism and the motor that shuts the door that is used to realize rotating drive, and the output shaft of the said motor that shuts the door is connected with first door-hinge through shaft coupling; Said folding transmission mechanism comprises driving gear, driven gear, first synchronous pulley and second synchronous pulley; Said driving gear is fixed on first door-hinge; Said driven gear is fixed in the rotating shaft; Said rotating shaft is fixedly mounted on the said inner door, and said driving gear and the engagement of said driven gear also are fixed with first synchronous pulley in said rotating shaft; Be fixed with second synchronous pulley on said second door-hinge, said first synchronous pulley and said second synchronous pulley are through be with engaged transmission synchronously.

Further, the said motor that shuts the door is the buried motor that shuts the door, and the output shaft of the said motor that shuts the door is connected with the lower end of said first door-hinge.

Further again, the upper end of said rotating shaft is set with two pairs of bearings, and said bearing is fixed on the inner door through bearing support.

The support column of the utility model is selected body of wall usually, promptly selects metope, pillar etc. in the body of wall, certainly, also can select other support columns.

The beneficial effect of the utility model is embodied in:

1, motor-driven folding door is trackless four fan folding doors, has eliminated the serial problem that traditional rail type folding door is brought.

2, motor-driven folding door adopts folding transmission mechanism, i.e. gear drive combines synchronous belt drive mechanism to realize the folding of four fan folding doors, does not exist the working angle problem, and two fan folding doors are folded fully.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

With reference to Fig. 1～Fig. 3; A kind of electronic four fan folding doors; The both sides of said motor-driven folding door are furnished with a fan outer door 1 and a fan inner door 2 respectively, are fixedly connected with first door-hinge 3 on the said inner door 2, and said first door-hinge 3 is linked on the door-hinge seat and can rotates; Be fixedly connected with second door-hinge 13 on the said outer door 1, said second door-hinge 13 is linked on the inner door 2 and can rotates; Said motor-driven folding door also comprises the motor 4 that shuts the door, and the output shaft of the said motor 4 that shuts the door is connected with first door-hinge 3 of lower end through shaft coupling 5; Said motor-driven folding door also comprises folding transmission mechanism; Said folding transmission mechanism comprises gear drive and band transmission synchronously; Said driving gear 6 is fixed on first door-hinge 3; Said driven gear 7 is fixed in the rotating shaft 8, and said driving gear 6 and said driven gear 7 engaged transmission also are fixed with first synchronous pulley 10 in said rotating shaft 8; Be fixed with second synchronous pulley 11 on said second door-hinge 13, said first synchronous pulley 10 and said second synchronous pulley 11 are through be with 12 engaged transmission synchronously.

Said door-hinge seat is fixed on body of wall or other support columns.The said motor 4 that shuts the door is the buried motor that shuts the door, and certainly, also can select the other types motor for use.Said rotating shaft 8 is fixed on the inner door 2, and the upper end of said rotating shaft 8 is set with two pairs of bearings 9, and said bearing 9 is fixed on the inner door 2 through bearing support.
