Abstract

A lock comprises a lock sleeve, a lock cylinder, an ejection shaft, a spring, a bolt and a slide plate, wherein the lock cylinder is provided with an axial guide hole axially penetrating through the lock cylinder, the key-hole end of the lock cylinder is provided with a guide plate, the other end of the lock cylinder is provided with a bolt seat, further the front end of the lock sleeve engaged with the key-hole end of the lock cylinder is provided with a guide platform, the rear end of the lock sleeve is provided with a rotary chamber, the inner wall of the lock sleeve is provided with an axial guide groove, one end of the ejection shaft is connected with the slide plate, the slide plate located inside an ejection-shaft hole extends out of the guide hole to be in sliding fit with the guide hole, the slide plate is engaged with the guide groove, and the guide plate is engaged with the guide platform. Due to the structure, the slide plate moves slightly in the guide groove of the lock sleeve while the ejection shaft moves slightly in the lock cylinder, and then the lock cylinder can be separated from the lock sleeve. Compared with the middle portion of the ejection shaft which has a cone in the prior art, the ejection shaft is shortened while the lock sleeve and the lock cylinder are shortened, thereby saving materials. Compared with the prior art, a pintle and a limit pin are saved, thereby simplifying the structure. Therefore, the utility model is adaptable to thinner doors.

Summary of the invention

The purpose of this utility model is: a kind of lockset is provided, and it is not only simple in structure, and volume is little, economical with materials.

The utility model is achieved in that a kind of lockset, comprise lock tube, lock core, apical axis, spring and dead bolt, lock core is installed in the lock tube, apical axis is installed in the lock core, the key hole that the apical axis hole is arranged on the lock core, is connected with the apical axis hole, its special character is: the axial pilot hole that radially connects is arranged on the lock core, and the key nose end of lock core has positioning disk, the other end that the dead bolt seat is arranged;

The front end that lock tube cooperates with lock core key nose end has guide table, rear end that rotating drum is arranged, and gathering sill is vertically arranged on the lock tube inwall;

Also comprise a slide, apical axis one end is fixedlyed connected with slide, and slide is positioned at the apical axis hole and stretches out pilot hole, is slidingly matched with pilot hole; Spring is installed in the apical axis hole between dead bolt seat and the apical axis end, and screw cooperates with the dead bolt seat, and spring position is fixed; Slide cooperates with gathering sill, and positioning disk cooperates with guide table.

Described a kind of lockset, its special character is: the guiding stop block is arranged on the described positioning disk; Described guide table has the guide and limit groove, and the guiding stop block is arranged on the positioning disk, and the guiding stop block cooperates with the guide and limit groove.

Described a kind of lockset, its special character is: the rotation slot of two slides is arranged in the rotating drum of lock tube rear end, and the rotation slot angle is 90 degree circular arcs; The guide and limit groove is 90 degree circular arcs.

Described a kind of lockset, its special character is: the guide and limit groove is 180 degree circular arcs.

A kind of lockset of the utility model adopts such structure by having, and slide is mobile small distance in the gathering sill of lock tube, and apical axis is mobile small distance in lock core, can realize that lock core separates with lock tube; In prior art, apical axis has cone, middle part to compare, and the apical axis contraction in length has shortened the length of lock tube, lock core simultaneously, has saved material.Compared with prior art, clasp nail, banking pin part have been saved, simplified structure; Can adapt to thinner door body.

The specific embodiment

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

Embodiment 1

As shown in Figure 1, a kind of lockset comprises lock tube 1, lock core 2, apical axis 3, spring 5 and dead bolt 7, and lock core 2 is installed in the lock tube 1, and apical axis 3 is installed in the lock core 2; As Fig. 2, Fig. 3, shown in Figure 4, there is the axial pilot hole 21 that radially connects in the key hole 25 that apical axis hole 24 is arranged on the lock core 2, is connected with the apical axis hole on the lock core 2, and the key nose end of lock core 2 has positioning disk 22, the other end that dead bolt seat 23 is arranged;

As Fig. 5, shown in Figure 6, the front end that lock tube 1 cooperates with lock core key nose end has the rear end of guide table 11, lock tube that the rotating drum 13 of slide is arranged, and gathering sill 12 is vertically arranged on lock tube 1 inwall;

Also comprise a slide 4, apical axis 3 one ends are fixedlyed connected with slide 4, and slide 4 is positioned at the apical axis hole and stretches out pilot hole 21, is slidingly matched with pilot hole 21; Spring 5 is installed in the apical axis hole 24 between dead bolt seat 23 and apical axis 3 ends, and screw 6 cooperates with dead bolt seat 23, with spring 5 fixed-site; Slide 4 cooperates with gathering sill 12, and positioning disk 22 cooperates with guide table 11.
