Abstract
The utility model discloses an electric folding door which comprises an active traction machine, wherein one side of the active traction machine is provided with a plurality of fan doors, the bottoms of the fan doors are connected to a slide seat, a folding bracket is arranged between the fan doors and the slide seat and provided with a plurality of supporting rods, the front ends and the rear ends of the supporting rods are mutually hinged, bearing holes are arranged on the surfaces of the supporting rods, and the bottoms of the supporting rods are movably connected with the slide seat. The utility model has the advantages that the unfolding or folding is stable, and the maintenance is easy.
Description
Technical field
The utility model relates to a kind of retractable door, specifically belongs to the folding carriage of electric extendable door.
Background technology
Electric extendable door is a kind of traction active machine with motor, initiatively machine starts the door body that drives a side, and with the retractable door that stretch mode is opened or closed, it is easy to use with it, handsome in appearance, many-sided advantage such as can electronicly control and obtained increasingly extensive application.The basic structure of existing electric extendable door comprises traction initiatively machine and the retractable door body that is attached thereto, wherein retractable door by a plurality of fans doors by about two-layer staggered form connecting rod and its transverse axis is hinged forms.Because retractable door is when launching or shrink, its connecting rod will be swung and expansion or contractile motion simultaneously, and promotion fan door launches or shrinks.The retractable door of this structure is stretching, extension or the contraction by connecting rod, promotes the expansion or the contraction of fan door, such structure needs bigger power to go to spur or promote the swing of connecting rod, but a wherein connecting rod bending or a damage arranged, will influence the use of whole retractable door, when changing wherein a connecting rod, need pull down whole door body, take off bad connecting rod, change new connecting rod, reinstall whole door body again, its monolithic linkage is more, connection is complicated, and maintenance is trouble very.
The utility model content
The purpose of this utility model is to address the aforementioned drawbacks, and a kind of stable, easy electric extendable door of maintenance that launches or fold is provided.
For achieving the above object:
Electric extendable door, comprise initiatively machine of traction, initiatively a side of machine is provided with several fan doors, fan door bottom is connected on the slide, be provided with a folding carriage between described fan door and the slide, folding carriage has some pressure pins, and the front and back ends between the pressure pin is hinged, the pressure pin surface has support holes, and the bottom of pressure pin and above-mentioned slide flexibly connect.
Described folding carriage, the rear end of last pressure pin is hinged successively with the front end of back one pressure pin.
Described folding carriage is connected with a plurality of slides, is connected with two hinged pressure pins between the pressure pin on two slides.
The fan door of described pressure pin top is provided with the jack-post of grafting support holes.
The front end of described folding carriage is connected with the active machine.
The beneficial effects of the utility model:
1, electric extendable door of the present utility model is provided with folding carriage in fan door bottom, traction initiatively machine affects folding carrier stretch or contraction, the fan door that is connected on the folding carriage launches or folds with folding carriage, the electric extendable door of this structure is stretching, extension or the contraction by folding carriage, realizes the expansion of electric extendable door or fold to use stablizing.
2, described folding carriage, the rear end of last pressure pin is hinged successively with the front end of back one pressure pin.Connect simply, be easy to realize,, only need pull down replacing, need not the whole electric extendable door of dismounting as wherein pressure pin damage, easy to maintenance, easy.

The specific embodiment
As shown in Figures 1 to 3: electric extendable door, comprise initiatively machine of traction, initiatively a side of machine is provided with several fan doors, fan door bottom is connected on the slide 3, be provided with a folding carriage 1 between described fan door and the slide 3, folding carriage 1 has some pressure pins 2, and the front and back ends between the pressure pin 2 is hinged, pressure pin 2 surfaces have support holes 201, and the bottom of pressure pin 2 and above-mentioned slide 33 flexibly connect.
Described folding carriage 1, the rear end of last pressure pin 2 is hinged successively with the front end of back one pressure pin 2.Connect simply, be easy to realize,, only need pull down replacing, need not the whole electric extendable door of dismounting as wherein pressure pin damage, easy to maintenance, easy.
Described folding carriage 1 is connected with between the pressure pin 2 on a plurality of slide 3, two slides 3 and is connected with two hinged pressure pins 2.
The fan door of described pressure pin 2 tops is provided with the jack-post of grafting support holes 201.
The front end of described folding carriage 1 is connected with the active machine.
