Abstract
The utility model relates to a pulley for sliding door and window, comprising prior inner and outer casing bodies, a pulley and a height adjusting bolt for the pulley, wherein an open slot which matches with the inner convex strip of an aluminum alloy frame is arranged on the top surface of the casing. The opening size of the outside of the open slot is a little smaller than the size of the inner convex strip of the aluminum alloy frame and closely matches with the inner convex strip; the opening size of the inside of the open slot is a little larger than the inner convex strip and movably matches with the inner convex strip. The open slot is arranged on the top surface of the pulley for sliding door and window, which uses the prior aluminum inner convex strip, closely matches the aluminum alloy frame, and can be fixed by just pushing forcedly, thereby arranging conveniently and rapidly, saving the process of manufacture of a bolt hole and the arrangement of bolt, improving the work efficiency greatly. The utility model is of simple and reasonable structure, and strong practicability.
Description
Technical field
The utility model relates to a kind of slide door or window pulley of alumium alloy door and window.
Existing aluminum alloy push-pull door and window trolley kind is more, structure is different.Two screws of its end face and the most employing of installing and fixing of aluminium alloy extrusions are connected.Palpus processing screw hole or through hole, its installation is time-consuming, and efficient is not high.Existing a kind of pulley is connected as shown in Figure 1 by the interior raised line screw of its side flanges and aluminum alloy frame, and it also needs a screw.
Summary of the invention
The purpose of this utility model aims to provide a kind of slide door or window pulley simple and reasonable, quick and easy for installation, to overcome weak point of the prior art.
A kind of slide door or window pulley by this purpose design comprises existing inner and outer shell, pulley and high and low position adjustment screw thereof, and its architectural feature is that outer casing top surface is provided with the open slot that matches with raised line in the aluminum alloy frame.
The opening size in the described open slot outside is slightly littler than raised line in the aluminum alloy frame, with interior raised line be snap-fit; The opening size of open slot inboard is bigger slightly than raised line in described, with interior raised line for movingly.Described open slot is vertical bar shaped, vertical bar necking down shape, stairstepping or gradually opens shape etc.
The end face of this slide door or window pulley is provided with open slot, and its utilizes the interior raised line of existing aluminium, with aluminum alloy frame be snap-fit, only need firmly one push away and can fix, quick and easy for installation; And saved the processing and the screw installation procedure of screw hole, can improve work efficiency greatly.It is simple and reasonable, and is easy to process, practical.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 2--Fig. 4, this slide door or window pulley 2 comprises existing inner and outer shell, pulley and high and low position adjustment screw thereof, its outer casing top surface is provided with outside necking down shape open slot 5.The opening size in the open slot outside is slightly littler than raised lines 3 in the aluminum alloy frame 4, with interior raised line be snap-fit; The opening size of open slot inboard is bigger slightly than raised line in described, with interior raised line for movingly.Described open slot 5 can be gradually opens shape, and promptly an end is little, and the other end is big; Whole piece opening size that also can open slot 5 ' is slightly littler than raised line in described, with interior raised line be snap-fit, as shown in Figure 5; Can also open slot 5 " opening be stairstepping, small end and interior raised line are snap-fit, big end and interior raised line are for movingly, as shown in Figure 6.During assembling, the open slot of this pulley only need tangle the interior raised line of aluminum alloy frame, and one pushes away in the lateral, can tighten to be fixed on the aluminum alloy frame.
In addition, can also flange or flange be set,, still belong to identical or the similar techniques scheme with goal of the invention of the present utility model with aluminum alloy frame inside wall when raised line (in not having) snap-fit in slide door or window pulley shell end face both sides.
