Abstract

The utility model discloses a pulley for a sash sliding window, which mainly comprises adjusting bolts 1, a fixing support 2, a moving support 3, semi-tubular rivets 4, retaining rings 6, screws 9, and a pulley device which is composed of a pulley support 5, an axle bumper 7, and steel balls 8. The moving support is arranged in the fixing support. The pulley device is arranged in the moving support and fixed on the fixing support by the semi-tubular rivets 4 and the retaining rings 6. Oblique chute holes with opposite angles are opened on the planes of the fixing support and the movable support to conduct fine adjustment to the pulley, and the pulley slides upwards and downwards along the oblique chute. Through pushed and pulled in testes for ten thousands of times, the utility model is not deformed and has the advantages of simple structure, convenient installation, low cost and long service life.

Description

Pulley for sash sliding window

The utility model is a kind of sliding sash pulley, is mainly used in various slide door or window, belongs to building field.

Existing sliding sash carriage mainly adopts track-type, and its method push-and-pull is not too flexible.Recently Patent Office of the People's Republic of China to disclose a kind of application number be 90219247.7 real abdomen steel sliding window, tourelle is adopted in its push-and-pull, mainly moves back and forth on fixed border by the roller that is installed in the movable sashes lower frame.This method also can reach the purpose of push-and-pull, but roller is to adopt polythene material, and it is more serious to wear and tear, and complexity is installed, and can not finely tune after the installation, if two not parallel rollers of just need changing of wheel cause great waste.

The purpose of this utility model is that a kind of simple in structure, easy for installation, long service life will be provided, the sliding sash pulley that the door and window push-and-pull also can be finely tuned flexibly.

The utility model is achieved in that and mainly comprises and adjust bolt 1, fixed support 2, travel(l)ing rest 3, semitubular rivet 4, and pulley gear and the back-up ring 6 be made up of pulley yoke 5, axle bumper 7, steel ball 8, screw 9, travel(l)ing rest 3 are contained in the fixed support 2, and pulley gear is contained in the travel(l)ing rest 3 and is fixed on the fixed support 2 with semitubular rivet 4 and back-up ring 6.Fixed support 2 is square and is drilled with fixing hole on the plane of a side, has tilted slotted hole on two planes vertical with fixing hole, and travel(l)ing rest 3 is long U-shaped and has angle and the opposite tilted slotted hole of fixed support 2 skewed slots on its two plane.

Be described in detail below in conjunction with accompanying drawing.

Fig. 1 is a front view;

Fig. 2 is a vertical view;

Fig. 3 is the fixed support sectional view;

Fig. 4 is the travel(l)ing rest vertical view.

Fixed support 2 is square and is drilled with the adjustment screw at its sealing part among Fig. 1, Fig. 2, is drilled with simultaneously two fixing holes on the plane of fixed mount 2 one sides, and it is 45 ° concentric tilted slotted hole (see figure 3) that two planes vertical with fixing hole have gradient.Travel(l)ing rest 3 is long U-shaped and has the concentric tilted slotted hole (see figure 4) opposite with fixed support 2 tilted slotted hole angles on its two plane, its sealing part boring screw.Adjust the screw of bolt 1 by fixed support and travel(l)ing rest to play a regulating action.Pulley gear is made up of pulley yoke 5, axle bumper 7 and steel ball 8, it is contained in the travel(l)ing rest 3, semitubular rivet 4 is riveted on pulley on the fixed support by the tilted slotted hole of fixed support and travel(l)ing rest, for riveting firmly, is lined with back-up ring 6 in riveted joint place of semitubular rivet 4.When adjustment bolt 1 clockwise rotates travel(l)ing rest 3 is pulled back, this moment, pulley fell, and when the adjustment bolt rotated counterclockwise, travel(l)ing rest moved on the pulley at this moment to reach.Since pulley can on move, fall and just can make pulley play the effect of fine setting.This sliding sash pulley is directly installed on the bottom of movable sashes with hold-down screw 9 by the fixing hole on the fixed support, it is moved back and forth on fixed window frame, make sliding sash more flexible.

The utility model is simple in structure, easy for installation, cost is low, the life-span is long, does not change through up to ten thousand these pulleys of test push-and-pull.This pulley also can be used for curtain roller.
