The specific embodiment

Referring to figs. 1 through Fig. 5, this sliding sash with disappearing screen window 7 is a rectangle structure, comprise a structure of rolling 1, two slide rails 2 and straining beams 3, two slide rails 2 are connected the both sides of structure of rolling 1 respectively with the one end, be wound with a gauze 6 in the structure of rolling 1, the movable end of this gauze 6 connects this straining beam 3, and these straining beam 3 two ends respectively are provided with the slippage in a slide rail 2 respectively of 34, two slide plates 34 of a slide plate.

Straining beam 3 two ends respectively are provided with a dead bolt 35 that stretches out to straining beam 3 end elasticity, and the head end of this dead bolt 35 has an inclined-plane 351; The other end of slide rail 2 is respectively installed lock body hook 5, and this lock body is linked up with 5 one sides and is provided with a corresponding to inclined-plane 51 of inclined-plane 351 incline directions with dead bolt 35, and opposite side is provided with a block face 53, is used for locking dead bolt 35; Lock body hook 5 is provided with at least one through hole 52, can wear a screw in this through hole, makes this lock body hook 5 be fixed in slide rail 2; The two ends of a spring 31 are connected between the end of two dead bolts 35; Wear an alignment pin 32 in the above-mentioned spring 31, this alignment pin 32 wears the end that connects two dead bolts 35.In addition, the inclined-plane 51 of lock body hook 5 also can be made as horizontal plane.

Straining beam 3 is provided with a switch enclosure 4, and these switch enclosure 4 two ends are respectively equipped with a left slider 41 and a right slide block 42; Left slider 41 and right slide block 42 respectively are provided with a projection 43, and dead bolt 35 ends respectively are provided with 33, two projectioies 43 of a groove and are stuck in two grooves 33; Be fixed with a block 44 in the switch enclosure 4, this block 44 is provided with at least one through hole 441, can make screw pass through this through hole 441, thereby this switch enclosure 4 is fixed on the straining beam 3; Be provided with a left side spring 411 in the left slider 41, the two ends of this left side spring 411 are connected between left slider 41 and the block 44; Be provided with a right side spring 421 in the right slide block 42, the two ends of this right side spring 421 are connected between right slide block 42 and the block 44.

The operating process of locking sliding sash with disappearing screen window 7 is as follows, and the operator spurs straining beam 3 downwards from initial position, makes straining beam 3 drive gauze 6 operation downwards in two slide rails 2; When pulling down when the lock body of slide rail 2 ends links up with 5, dead bolt 35 and lock body hook 5 contacts by two inclined-planes, the inclined-plane 351 of dead bolt 35 is under the thrust on the inclined-plane 51 of lock body hook 5, and in the withdrawal straining beam 3, straining beam 3 and gauze 6 continue descending, run to by behind the lock body hook 5, thrust disappears, and at this moment, dead bolt 35 ejects under the active force of spring 31, dead bolt 35 forms locking states with the block face 53 of lock body hook 5, thus locking sliding sash with disappearing screen window 7.At this moment, if continue pulling straining beam 3 downwards, then the slide plate 34 at straining beam 3 two ends is blocked by lock body hook 5, makes slide plate 34 can not continue downward slippage, thereby straining beam 3 can not be moved downwards under the effect of external force again, damages its structure in order to avoid straining beam 3 is deviate from the back.

The operating process of opening sliding sash with disappearing screen window 7 is as follows, operating personnel only need the left slider 41 and the right slide block 42 at switch enclosure 4 two ends are inwardly pushed away, thereby compression left side spring 411 and right side spring 421, make two projectioies 43 of left slider 41 and right slide block 42 drive dead bolt 35 compression springs 31, so that in the dead bolt 35 withdrawal straining beams 3, this moment, lock body hook 5 was no longer to 35 inhibitions of dead bolt, make dead bolt 35 and corresponding lock body hook 5 break away from, straining beam 3 upwards moves to initial position with gauze 6, thereby opens sliding sash with disappearing screen window 7.

Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also comprises these changes and modification interior.
