The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

A kind of lockset, comprise outer lock core 7 and internal cylinder 2, on described outer lock core 7, have dieback hole 8, the vertical and intersectant centerline of the center line in dieback hole 8 and outer lock core 7, the center line of the center line in dieback hole 8 and spring eye 3 is positioned at same plane, and this plane is vertical with the center line of outer lock core 7.The shortest spring eye 3 of spring pearl 5 that this spring eye 3 is internal cylinder 2.The angle of the center line of the center line in dieback hole 8 and spring eye 3 is 40 degree, and crossing with the center line of outer lock core 7.In dieback hole 8, there are dieback pin and dieback cover 13, described dieback pin is made up of syringe needle 9, groups of springs 10, connecting rod 11 and spring leaf 12, described syringe needle 9 is fixed on connecting rod 11 one end, groups of springs 10 is enclosed within on connecting rod 11, connecting rod 11 other ends are spring leaf 12, spring leaf 12 is in the endoporus of dieback cover 13, and syringe needle 9 is the center line of lock core 7 outward, and dieback cover 13 is fixed in the hole of dieback hole 8 near the external surface of outer lock core 7.The aperture in dieback hole 8 equates or is slightly larger than the aperture of spring eye 3.

Operating principle of the present utility model: in the time meeting with improper unblanking, the contact surface that the person of unblanking can form spring pearl 5 and spring pearl 4 overlaps with the contact surface that internal cylinder 2 forms with outer lock core 7, then rotate internal cylinder 2, in the time turning to certain angle, corresponding spring eye 3 overlaps with dieback hole 8, under the effect of dieback needle spring group 10 power, promoting syringe needle 9 moves to the centerline direction of outer lock core 7, touch with the spring pearl 5 of internal cylinder, and continue to promote spring pearl 5 and move to the centerline direction of outer lock core 7, syringe needle 9 can enter in the spring eye 3 of internal cylinder 2, simultaneously, spring leaf 12 departs from the endoporus of dieback cover 13, under tension force effect, open, the outer ring surface that overlaps 13 one end with dieback contacts, now, internal cylinder 2 cannot be rotated, simultaneously because spring leaf 12 diebacks on the outer ring surface of dieback cover 13, also cannot promote dieback pin and outwards move by stirring spring pearl 5, realized the locking function of lock.

In addition, connecting rod 11 and spring leaf 12 can be combined into one, and connecting rod 11 splits into two parts from 9, syringe needle, and two parts have formed spring leaf 12.This combination is also the another kind of structure of dieback pin.

For dieback device, another structure is moved back pin by dieback pin, dieback cover 19 and resistance and is formed, and dieback pin is mainly made up of syringe needle 22, connecting rod 20 and groups of springs 21, on the face of cylinder of dieback cover 19, has perforation, and resistance is moved back pin and is made up of pin 18 and resistance extractor group 17.Described resistance is moved back pin in hole 16 is moved back in resistance, and resistance is moved back hole 16 on outer lock core 14, and it is crossing with the center line in dieback hole 15 that the center line in hole 16 is moved back in resistance, and intersection point is on the center line of dieback cover 19, and the center line that the center line of the perforation of dieback cover 19 and hindering moves back hole 16 partially overlaps.In the time meeting with improper unblanking, syringe needle 22 enters in the spring eye 3 of internal cylinder 2, pull connecting rod 20 to move forward, the pin 18 that pin is moved back in resistance moves forward under the thrust of resistance extractor group 17, and pin 18 leading sections are positioned at the rearward end position of connecting rod 20, now, internal cylinder 2 cannot be rotated, simultaneously because pin 18 has stoped connecting rod 20 outwards to move, also cannot promote dieback pin and outwards move by stirring spring pearl 5, realize the locking function of lock.

There is shell outer lock core outside, and dieback cover and resistance extractor group cannot move.
