Abstract
The utility model relates to a hanging pulley for doors and windows. In the existing hanging pulley, two limiting pulleys whose directions are perpendicular to the direction of a bearing pulley are arranged above a bearing pulley pair in general. In the utility model, a directive wheel is arranged between the bearing pulley pair, and the directive wheel is arranged in the upper orbit with a star-shaped cross section of a door or a window. The directive wheel is inlaid in a guiding orbit formed by upright side walls on the middle part of the lower opening of the orbit of the door or the window, which has the function of preventing the pulley from swaying to the left and the right sides. The utility model has the advantage of simple structure, and besides, the utility model can guarantee the door or the window fixed on the utility model to move along the guiding orbit arranged in the centerline position of the orbit of the door or the window.
Description
The utility model belongs to a kind of door and window suspension type pulley.
Slide door or window can slide in the door and window track by pulley fixed thereon, and the suspension type pulley is to be fixed on slide door or window top, and its load-bearing pulley makes door and window make suspension type along the window rail road of calling and slides.This pulley generally is to establish a pair of load-bearing pulley, places cross section to be respectively
On the limit, the track left and right sides of type (referring to 6), in order to prevent to swing, prior art is provided with a pair of spacing pulley (10) vertical with load-bearing pulley direction above the load-bearing pulley, withstand on
On the sidewall about the type track, make the slide door or window held stationary, its structure more complicated.
The utility model aims to provide a kind of door and window suspension type pulley simple in structure.
The technical scheme that realizes above-mentioned purpose is: the utility model comprises fixed mount (4), and fixed mount is provided with pulley bracket (2), and pulley bracket is provided with the load-bearing pulley of symmetry to (1), it is characterized in that, the load-bearing pulley between be provided with a directive wheel (3).
Operating principle of the present utility model is: door and window is fixed on the fixed mount (4) of this suspension type pulley, with the load-bearing pulley to placing cross sections respectively is again
On the limit, the left and right sides, window rail road to the doorstep of type,
The type sidewall that under shed two ends, window rail road upwards hold up of calling forms a guide rail (6), and the directive wheel of this suspension pulley is embedded in this guide rail.The load-bearing pulley leans against the effect of the directive wheel of motion in the guide rail when sliding on the track of the left and right sides like this, whole device can not vacillated now to the left, now to the right, and can only move along the guide rail of door and window track.
The utility model only is provided with a directive wheel, compares with two spacing pulleys in the existing same device, and is simple in structure, and the door and window that this pulley can guarantee to be contained on the fixed mount accurately moves along the guide rail that is located on the door and window track centerline.

The embodiment explanation
This example is provided with pulley bracket 2 on fixed mount 4, be arranged with two groups of load-bearing pulleys to 1 on pulley bracket, and they are located at the two ends of pulley bracket respectively, and a directive wheel 3 vertical with load-bearing pulley direction established in the middle and lower part between a pair of therein load-bearing pulley.
Usually the suspension type pulley only is provided with a pair of load-bearing pulley, minimumly on the Yishanmen window like this will pacify two assembly pulleys with the maintenance balance, and this example is established two pairs of load-bearing pulleys, can keep balance so only pacify one on the Yishanmen window.
The also supporting following leading block that is installed in the door and window bottom of establishing of this example simultaneously, referring to Fig. 5, its structure is, adorns a rotating cylindrical time leading block 8 on lower fixed frame 7, a universal pearl 9 is established on the leading block top under cylindrical.Using method is: leading block under installing in the door and window bottom, cylindrical leading block is down embedded in the lower railway of door and window, cylindrical side slides along the track two side, the universal pearl at its top is then along door and window lower railway top slide, and the structure of Pei Heing can further reduce the frictional force of slide door or window so up and down.
Claims (4)
1, door and window suspension type pulley comprises fixed mount (4), and fixed mount is provided with pulley bracket (2), pulley bracket be provided with the symmetry the load-bearing pulley to (1), it is characterized in that, the load-bearing pulley between be provided with a directive wheel (3).
2, door and window suspension type pulley according to claim 1 is characterized in that, described directive wheel (3) be located at the load-bearing pulley between the middle and lower part.
