Abstract
A kind of foldable push and pull door and window lower sheave component is equipped with sister block in the side of pulley bracket, and the other side is equipped with single-sheaved block, and the lower end of pulley bracket is equipped with locating wheel.Mounting hole is arranged at the pulley bracket top.The sister block and single-sheaved block by respective pulley fixing axle, be rotatably installed on pulley bracket two sides.The locating wheel is rotatably installed on pulley bracket lower end by locating wheel screw.Its advantage is that foldable push and pull door and window stress balance, pulley sliding in switching process is smooth, there is phenomena such as swinging or derailing in the anti-limited slip wheel of energy.Foldable push and pull door and window can be made to close rear wheel component Hide All in door and window sectional, and the center of gravity of door and window fan, all in the range of door and window fan, center of gravity is not exposed not to be deviated, and the stability of door and window is improved.
Description
Technical field
The utility model relates to the attachmentes for sliding wing, belong to door and window hardware field, espespecially a kind of sliding folding door
Window downslide wheel assembly.
Background technique
Foldable door and window is a kind of common door and window, is installed between the upper sliding rail of sash and glidepath.Existing folding
It is generally fitted with a lower sheave below folded door and window, top is generally fitted with hanging wheel on one, and the lower sheave is installed on glidepath
On, the upper hanging wheel is installed on sliding rail, and the Foldable door and window is by lower sheave and upper hanging wheel on upper sliding rail and glidepath
Sliding, the upper hanging wheel and lower sheave undertake the weight of door and window.
Existing sliding folding door fan material is mostly all wider in the market, and downslide wheel assembly is mostly in foldable push and pull door and window
It is exposed to close rear wheel components, causes the centre-of gravity shift of folding door sash, so that foldable push and pull door and window use is made to have some setbacks,
It is unsightly clean and tidy.
Summary of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of foldable push and pull door and window lower sheave groups
Part.It is intended to that downslide wheel assembly is made to adapt to the wide foldable push and pull door and window of extremely narrow fan, it is complete to close rear wheel component in foldable push and pull door and window
Portion is hidden in door and window sectional, and the center of gravity of door and window fan, all in the range of door and window fan, center of gravity is not exposed not to be deviated, and is mentioned
The stability of high door and window.
And the locating wheel by being arranged in pulley keeps pulley sliding more smooth, the anti-limited slip wheel of energy occurs swinging and derail
The problems such as.
The technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of foldable push and pull door and window lower sheave
Component, including pulley bracket, it is characterised in that: sister block is installed in the side of pulley bracket, the other side is equipped with single-sheaved block,
The lower end of pulley bracket is equipped with locating wheel.
Into some ground:
Mounting hole is arranged at the pulley bracket top.
The sister block and single-sheaved block by respective pulley fixing axle, be rotatably installed on pulley bracket two sides.
The locating wheel is rotatably installed on pulley bracket lower end by locating wheel screw.
The beneficial effects of the utility model are: foldable push and pull door and window stress balance, pulley sliding in switching process is smooth,
There is phenomena such as swinging or derailing in the anti-limited slip wheel of energy.Foldable push and pull door and window can be made to close rear wheel component Hide All in door and window fan
In profile, and the center of gravity of door and window fan, all in the range of door and window fan, center of gravity is not exposed not to be deviated, and the stabilization of door and window is improved
Property.

Specific embodiment
Referring to attached drawing, a kind of foldable push and pull door and window lower sheave component of the utility model, including pulley bracket 1, feature exists
In: sister block 3 is installed in the side of pulley bracket 1, the other side is equipped with single-sheaved block 6, and the lower end of pulley bracket 1 is equipped with fixed
Position wheel 7.
In the embodiments of the present invention:
Mounting hole 101 is arranged at 1 top of pulley bracket.
The sister block 3 and single-sheaved block 6 are rotatably installed on 1 liang of pulley bracket by respective pulley fixing axle 5,2
Side.
The locating wheel 7 is rotatably installed on 1 lower end of pulley bracket by locating wheel screw 8.
When using installation: the utility model being installed under the center pillar section bar 9 of foldable push and pull door and window 13 by installation screw 4
At end.The two groups of pulley wheels 3,6 in left and right can be such that the stress in switching process of foldable push and pull door and window 13 more balances, and locating wheel 7 can make
Pulley sliding is more smooth, while phenomena such as swinging or derailing occurs in the anti-limited slip wheel of energy.Foldable push and pull door and window closes rear wheel group
Part Hide All is in door and window sectional, and the center of gravity of door and window fan is all in the range of door and window fan, and center of gravity is not exposed not partially
It moves, improves the stability of door and window.
