The purpose of this utility model provides a kind of handle and is difficult for throwing off safety, a kind of crescent shape sliding sash closer easy to use, attractive in appearance.

Task of the present utility model is finished like this, it comprises lock core base, by inserting drive rod and the inner transmission on the swing link wrench, it is characterized in that the sliding shoe center has sliding eye to be enclosed within on the drive rod of lock, there is retainer spring the drive rod both sides, there is a plate ear lateral attitude of vertical slipper, it slides up and down by lock core base side breach, protrude on the slide block bottom surface positioning boss is arranged, circle plectrum centre bit is equipped with rotating hole and is pressed in and is enclosed within on the drive rod on the slide block, have a gap on the circle plectrum circumferential edges, spanner was 180 ° of angles when the spanner rotation drove rotation by drive rod, pin slide door or window by crescent shape on the spanner and lock nose, sash was locking states when the gap when slide block therewith rotates with the circle plectrum on positioning boss and the circle plectrum matched, and this moment, handle can not rotate.

The utlity model has easy for installationly, reasonable in design, by the drive rod transmission that matches with its internal construction, utilize outward appearance to design cleverly, crescent shape just can be pinned slide door or window, and both safety was attractive in appearance again.

Fig. 1 is the side schematic view of the utility model structure;

Fig. 2 is a front view of the present utility model;

Fig. 3 is the structural representation that circle plectrum and slide block match;

Fig. 4 is the structural representation after circle plectrum and slide block break away from;

Describe embodiment in detail in conjunction with above accompanying drawing, it is by handle 1, base 3, slide block 5, circle plectrum 11 4 parts are formed, there is a drive rod 2 at handle 1 back side on the center of circle, become one with drive rod 2 with the stamping forming handle 1 of metal material, there is retainer spring drive rod 2 both sides, base 3 is long troughs, there is a circular hole 4 at base 3 centers, there is a breach 7 side, have on the upper and lower end face of circular hole 4 and the fixing screw of sash, drive rod 2 is inserted in 4 li of the circular holes at base 3 centers, is inserted in slide block 5 on it again, overlap plectrum 11 above the slide block 5 again, drive rod 2 can rotate for 4 li at circular hole, the shape of slide block 5 is squares, and there is shape hole, ellipse garden 10 at the center, and there is a plate ear 8 lateral attitude of vertical slipper 5, whole slide block 5 is to use the metal material punch forming, be by protruding the location concave station 9 on slide block 5 bottom surfaces when distinguishing the positive and negative of slide block 5, be provided with on the drive rod 2 of 4 li of circular holes at these casing pressure base 3 centers of location concave station 9 that the breach that plate ear 8 falls into core base 3 sides can slide up and down for 7 li.It is circular justifying plectrum 11 shapes, and there is square hole 13 at the center, has a gap 12 on the edge of circumference, and punching press forms one, justifying plectrum 11 glands on slide block 5.Be with base 3, slide block 5, circle plectrum 11 on the whole drive rod 2, after encapsulation is intact, a spacing protruding square hole that exceeds round plectrum 11 centers is arranged on the drive rod 2, rotate time limit rounding plectrum 11 at drive rod 2 and be unlikely to skid off drive rod 2, rivet tightly with rivet by the pin-and-hole on the base 3.During use, the screw up and down on the base 3 is fixed on the sash, and handle 1 is threaded to left to be opened or locking, and when handle 1 was threaded to 180 °, slide block and plectrum rotated simultaneously, and the gap 12 on the at this moment round plectrum 11 breaks away from (see figure 3) with the positioning boss 9 of slide block 5.Promptly open sash, as close sash and stir plate ear 8 on base 3 sides.Plate ear 8 is unlikely to back and forth loosening when plate ear 8 is slided in the base breach with slide block 5, special overlapping below slide block is lined with a spring leaf 6, handle 1 homing, at this moment slide block 5 rotates simultaneously with circle plectrum 11, and gap 12 and the positioning boss on the slide block 59 on the circle plectrum 11 pin (see figure 2)s.When can not rotating, pins by handle sash.
