Abstract

The utility model relates to a stair-shaped high airtight downward sliding device for a door and window, which comprises a door and window sash, a lower guide block and a low slide, wherein, the lower guide block and the low slide are arranged on both ends of the bottom of the door and window sash. The utility model is characterized in that the low slide forms a stair shape; sealing rubber strips are arranged among stairs of the lower slide; the interior of each stair of the lower slide is provided with a dense-prevention stop dog. The utility model has the advantages of simple and reasonable structure, convenient installation and operation and absolute and smooth drainage; the utility model can make the door and window sash smoothly slide and can also improve the security and the sealing performance of the door and window sash.

Description

The high airtight down slide device of the pure notch cuttype of door and window

The utility model relates to a kind of down slide device, the high airtight down slide device of the pure notch cuttype of particularly a kind of door and window.

Existing alumium alloy door and window are smooth and easy as requiring to slide, and be provided with certain interval between just must and gliding at bar, but this gap can influence the sealing performance of bar again, infiltration easily; As in gliding, increasing sealing joint strip, can influence bar again and slide freely suitable.The both is difficult to the effect that reaches desirable.

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and draining is unobstructed, and it is smooth and easy that bar is slided, the high airtight down slide device of the pure notch cuttype of the door and window that sealing performance is good again.

The purpose of this utility model can reach by following measure: the utility model comprises bar, is loaded on lower guide block, the downslide at two ends, bar bottom, it is characterized in that: gliding is stairstepping, between the ladder that glides, be provided with sealing joint strip, only crammed piece all is housed in the every grade of ladder that glides.

The purpose of this utility model can also reach by following measure: gliding is absolute stairstepping, and one-level is higher than one-level, and every grade is smooth.All be provided with catching groove between the every grade of ladder that glides, sealing joint strip is loaded in the catching groove.In every grade of ladder of sending down the fishbone, all be provided with chute, at the two ends of chute and central part only crammed piece all is housed.

Fig. 1 is the structure elevation of glide (the band sealing joint strip reaches and ends the crammed piece);

Fig. 2 is the structure side view of glide (the band sealing joint strip reaches and ends the crammed piece):

Fig. 3 is the structure vertical view of glide (the band sealing joint strip reaches and ends the crammed piece);

When Fig. 4 opens for bar and the structural section (A-A) of downslide figure;

When Fig. 5 closes for bar and the structural section of downslide (B-B) figure;

Fig. 6, Fig. 7 are the lower guide block and the position view that ends the crammed piece that is loaded in the downslide that is loaded on two ends, bar bottom.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1～Fig. 3, gliding 3 is pure stairstepping, and one-level is higher than one-level, and every grade be smooth, and draining is definitely smooth and easy; All be provided with catching groove 3-2 between every grade of ladder of downslide 3, sealing joint strip 4 is loaded in the catching groove 3-2; In addition in the 3 every grade of ladders that glide, all be provided with chute 3-1, only crammed piece 5 all be housed at two ends and the central part of chute 3-1.End crammed piece 5 and be provided with ladder position 5-1, when the following block 2 that is loaded on the door and window bottom slides into this position, can produce certain displacement, whole bar is oppressed to sealing joint strip 4 directions.

With reference to Fig. 4～Fig. 7, when bar 1 was in the enable possition, the lower guide block 2 of its bottom was positioned at the chute 3-1 of downslide 3, and bar 1 keeps the certain interval (see figure 4)s with sealing joint strip 4, make the resistance of bar 1 no sealing joint strip 4 in the push-and-pull process, it is smooth and easy especially to slide.When bar 1 is in the closed position, the lower guide block 2 at its two ends, bottom just in time enters in the only crammed piece 5 of being located at glide 3 one ends and central part, owing to end in the crammed piece 5 and be provided with ladder position 5-1, when so lower guide block 2 slides the ladder position 5-1 of crammed piece 5 to end from the chute 3-1 that glides, can produce certain displacement, make bar 1 to sealing joint strip 4 compressings, reach the effect of sealing; While is the anti-external broach of auxiliary door sash also, has remedied the tightness of lower guide block 2 and the safety of bar.

The utility model has following advantage compared to existing technology: simple and reasonable, install Easy to use, draining is definitely unobstructed; It is smooth and easy that bar was slided, and can strengthen door and window again Security and the sealing property of fan.
