The utility model content

The purpose of this utility model is exactly that a kind of simple for structure, assembling is easy to maintenance, transmission of power is effective retractable door is provided at the deficiencies in the prior art part.

For achieving the above object, the utility model by the following technical solutions:

A kind of retractable door, it comprises 1, doorframe 2 and road wheel 3, it is characterized in that: described doorframe 2 is to be interlinked by last lower

pillar stand joint

24,25 by a plurality of

columns

21,22 to form,

column

21,22 and

column joint

24,25 constitute the triangular shape door row 23 who is connected with each other, power is connected through the hinge during stretching

motion column joint

24,25 transmits, and road wheel 3 is installed in 1 and doorframe 2 bottoms.

Above-mentioned retractable door, it is further characterized in that described 1 is the triangle gate head, described doorframe 2 is front and back two rows, is linked to each other by a plurality of lower and upper cross-members 26,27 between two rows; Described doorframe 2 also comprises crossbar 28, described crossbar 28 is a kind of rod member perforation syndetons, between both sides triangular shape door row 23, links to each other with triangular shape door row 23 by crossbar long intubation tube 281, two rows before and after crossbar 28 also can be are linked to each other by the short intubate 282 of a plurality of crossbars between two rows.Crossbar can be W shape or quadrangle or the like.

Above-mentioned retractable door, it is further characterized in that described crossbar long intubation tube 281 is made up of long inserted link and long inserted link joint, the short intubate 282 of described crossbar is made up of short inserted link and short inserted link sleeve; Described top rail 26 is made up of upper plunger, upper lateral tube, top rail skeleton and ornament.

Above-mentioned retractable door further is characterised in that, described column joint the 24, the 25th, a kind of circular arc column primary and secondary joint; Secondly, on each road wheel 3 top wheel cover 31 is housed all.

The beneficial effects of the utility model are: at first, its breaks through the frame mode of existing retractable door on market, and is simple for structure, the saving of labor, save time, material-saving, reached both simple and clear, elegant in appearance again purpose on the general effect; The second, retractable door assembling, easy to maintenance, cost performance height; The 3rd, it changed traditional retractable door the chute-type structure, drive the mode of doorframe main frame level run by the crossbar transmission, the utility model is the chain drive of triangle gate row hinge, novel structure, reasonable in design, operate steadily, reliable operation.
