Abstract
The utility model provides a height adjustable double-roller guide pulley for an aluminum alloy door (window), which comprises a guide pulley base, a guide pulley and a guide pulley rack. The utility model is characterized in that the height adjustable double-roller guide pulley is also provided with a swinging arm, an adjusting nut and an adjusting screw. The lower end of the swinging arm is hinged with a center axle of the guide pulley rack, and the center axle is supported on long circular holes vertically arranged on both sides of the guide pulley base. The adjusting nut is in a n shape, the opening end of the adjusting nut is hinged with the upper end of the swinging arm, and the center of the back end surface of the adjusting nut is provided with a thread hole. The adjusting nut passes through a through hole of the back end surface of the guide pulley base to be connected with a thread hole of the adjusting nut. The double-roller guide pulley has the advantages of adjustable center height, high installation accuracy, low noise, stable movement, etc., and is suitable for the aluminum alloy door (window).
Description
The utility model relates to a kind of alumium alloy door and window two-wheel guide wheel of improved guide wheel, particularly a kind of adjustment height.
China's utility model patent (ZL97209063.0) discloses a kind of " alumium alloy door and window two-wheel guide wheel ", this two-wheel guide wheel is characterised in that guide wheel is on two, be installed on the same wheel stand along guide rail line, compare with the guide wheel of existing single-wheel structure and have big, the advantage such as flexible of sliding of little, the bearing capacity of wearing and tearing.Yet, the centre-height of not enough is guide wheel is nonadjustable, only relies on the workman guide wheel to be contacted boring suitable installing hole on the door and window with guide rail when assembling, and error is bigger, be difficult to improve door and window installation accuracy, move not steadily, noise is big, influence functional performance.
The purpose of this utility model is to provide a kind of installation accuracy height, adjustment height alumium alloy door and window two-wheel guide wheel that functional performance is good.
Task of the present utility model is achieved in that this two-wheel guide wheel includes wheel seat, guide wheel and wheel frame, it is characterized in that swing arm in addition, adjusting nut and adjustment screw, swing arm lower end are articulated on the central axis of wheel frame, and this central axis is supported on the slotted hole of vertically offering the wheel seat both sides, adjusting nut is the type, its openend and rocking arm upper end are hinged, and the end face center has screwed hole thereafter, and the through hole that adjustment screw is passed the wheel seat rear end face is connected with the screwed hole of adjusting nut.
The utility model is to use like this: after this two-wheel is assembled to alumium alloy door and window with the pilot hole of its wheel seat end face, and by the rotation adjustment screw, but adjusting nut move left and right just, the upper end of hinged with it swing arm is move left and right thereupon also.Because the rocking arm lower end is supported on the slotted hole of wheel seat by the central axis of wheel frame, move left and right makes its upper end can only do a kind of swinging around the central axis rotation thereupon.When rocking arm was in vertical position, its upper surface and adjusting nut end face were close to the wheel seat end face, and wheel seat end face to the distance at wheel frame central axis center is maximum at this moment; And when the generation of rocking arm upper end is mobile; just produce the space between rocking arm end face and the wheel seat end face, the effect of being stressed, the wheel frame central axis just up moves along the slotted hole of wheel seat; make the rocking arm upper surface contact the wheel seat end face again, and wheel seat end face to the distance at wheel frame central axis center just reduces at this moment.Therefore, after the two-wheel guide wheel is installed to aluminum window, just can makes guide wheel be close to guide rail by the turn adjustment screw and be unlikely the generation error, overcome the deficiency of prior art effectively, having the guide wheel centre-height can regulate, the installation accuracy height, and noise is low to move advantages such as steady with door and window.
Below in conjunction with accompanying drawing structure of the present utility model is further described.
Fig. 1 is a kind of concrete structure partial sectional view of the utility model.
Fig. 2 is along the sectional view of A-A line among Fig. 1.
As depicted in figs. 1 and 2, swing arm 5 lower ends are articulated on wheel frame 7 central axiss 8 that two guide wheels 6 are housed.The central axis 8 of wheel frame 7 is supported in the slotted hole 9 of wheel seat 1 two sides.Described adjusting nut 4 is the font, and is by a pivot 3 that its openend and Rocker arm 5 upper end is hinged.Have a screwed hole 2 on adjusting nut 4 rear end faces, the through hole 11 that adjustment screw 10 is passed wheel seat 1 rear end face is connected with the screwed hole 2 of adjusting nut 4.
The utility model is fit to alumium alloy door and window to be used.
