Abstract
The utility model belongs to building attachment technique field, particularly a kind of foldable push and pull door and window lower pulley apparatus.This foldable push and pull door and window lower pulley apparatus comprises sheave segment and hinge fraction, it is characterized in that: described sheave segment comprises pulley spindle, pulley base and pulley cover plate, be provided with pulley between pulley base and pulley cover plate, three combines fixing through pulley, pulley base and pulley cover plate by pulley spindle successively; Hinge fraction comprises hinge seat, decorations cover, hinge axis, fixed bar and hinge, hinge upper end is provided with axle sleeve, hinge axis is successively through circular hole and the pan of hinge seat, in the screwed hole of hinge axis, holding screw is installed, fixed bar is successively through hexagonal hole and the decorations cover of hinge seat, and sheave segment and hinge fraction link together by fixed bar.Reasonable in design, easy for installation; Foldable push and pull fan hoisting capacity is little, can avoid because dust and foreign material are deposited on the drawback that push-and-pull that slide rail causes has some setbacks, long service life.
Description
(1) technical field
The utility model relates to a kind of foldable push and pull door and window lower pulley apparatus, belongs to building attachment technique field.
(2) background technology
Foldable push and pull door and window popular on present market adopts the load-bearing of lower sheave parts, load-bearing slide rail is arranged on below foldable push and pull door and window, this design also exists the defect that slide rail easily deposits dust and foreign material, as discharged not in time, easy generation pulley is obstructed, the problem that push-and-pull has some setbacks, because slide rail fluting size is unsuitable excessive, therefore dust and foreign material just not easily discharge slide rail; And hinge is when being arranged on section bar, only coordinate with the plane of two on section bar by hinge, be fixed on above section bar with self threading pin by middle hinge, after having grown service time, middle hinge and section bar can offset, cause fan sagging.
(3) summary of the invention
The utility model, in order to make up the defect of prior art, provides a kind of structure simple, and it is little that easy to use and foldable push and pull fans hoisting capacity, the foldable push and pull door and window lower pulley apparatus of long service life.
The utility model is achieved by the following technical solution:
A kind of foldable push and pull door and window lower pulley apparatus, comprise sheave segment and hinge fraction, it is characterized in that: described sheave segment comprises pulley spindle, pulley base and pulley cover plate, be provided with pulley between pulley base and pulley cover plate, three combines fixing through pulley, pulley base and pulley cover plate by pulley spindle successively; Described hinge fraction comprises hinge seat, decorations cover, hinge axis, fixed bar and hinge, hinge upper end is provided with axle sleeve, hinge axis is successively through circular hole and the pan of hinge seat, in the screwed hole of hinge axis, holding screw is installed, fixed bar is successively through hexagonal hole and the decorations cover of hinge seat, and sheave segment and hinge fraction link together by fixed bar.
Wherein:
Described fixed bar inserts in the hexagonal hole of pulley base, is fixed on above pulley base by straight pin.
Described sheave segment is arranged on inside gliding structural section, and two side rollers and gliding structural section inwall match, and play the guiding role to foldable push and pull door and window, and hinge fraction connects two adjacent fan Foldable fans.
Described hinge and sectional are connected by hinge hook, and both are fixing more firm.
Described hinge axis, fixed bar adopt 304 stainless steels, can bear the weight of larger door leaf; Described pulley adopts high-strength resin material injection mo(u)lding, and design and select material is reasonable, and when pulley rolling is rubbed, abrasion resistance is stronger, and load-bearing is better.
The utility model is realized by following operating principle: the utility model does not bear the own wt of slide door or window, can avoid because dust and foreign material are deposited on the drawback that push-and-pull that slide rail causes has some setbacks, pulley has side righting and guide function, makes door leaf lighter, smooth and easy in greater pressure lower slider.
The beneficial effects of the utility model are: reasonable in design, easy to install; Foldable push and pull fan hoisting capacity is little, can avoid because dust and foreign material are deposited on the drawback that push-and-pull that slide rail causes has some setbacks, Material selec-tion accurately, long service life.
