AI Technical Summary

Problems solved by technology

Because the delay anti-theft mostly appears in the form of a delay alarm circuit, and the lock itself can still be opened, encountering electronic interference, the anti-theft effect is not ideal, and it is often easy to misreport
With the simple combination of the two technologies, although the anti-theft effect can be improved, it is still not satisfactory.

Embodiment 1

[0035] Embodiment 1: as figure 1 Shown:

[0036] When the lock core 29 is a one-way unlocking delay trigger in the door opening direction: the lock core 29 includes an outer core body 19 and an inner core body 21, the inner core body 21 is fixedly connected with the toggle wheel 6, and the inner core body 21 is connected to the key under the action of the key. The outer core body 19 is rotatably connected, and one end of the inner core body 21 is provided with a push rod sliding cavity, and the push rod sliding cavity communicates with the keyhole provided at the other end of the inner core body 21, and the push rod 17 is sleeved in the inner core body 21 and is connected with the push rod sliding cavity. The rod sliding cavity is slidingly connected.

[0037] The shaft body of push rod 17 is provided with lug 20, and the push rod sliding cavity side of inner core body 21 is provided with straight groove, and outer core body 19 side is provided with outer core body guide groo...

Embodiment 2

[0050] Embodiment 2: as figure 2 Shown:

[0051] The lock cylinder 29 is a two-way unlocking. When the door opening direction is delayed and triggered: the lock cylinder 29 includes an outer core 19 and two inner cores in the A direction and the B direction. The block 22 is connected to the connection groove of the two-way toggle wheel 30, and the B-direction inner core is connected to the connection groove of the two-way toggle wheel 30 through the B-direction shift block 23, and the outer core body 19 and the A-direction and B-direction two inner core bodies It is rotatably connected, and the inner side of the A-direction core body 27 is provided with a push rod sliding chamber, which communicates with the key hole provided on the other side of the A-direction inner core body 27, and the A-direction push rod 26 is set on the A is in the inner core body 27 and is slidably connected with the push rod sliding cavity and the key hole.

[0052] The body of the A-direction push...

Embodiment 3

[0062] The body of the A-direction push rod 26 is provided with a protrusion 20, and the rod head is provided with two positioning guide holes, and between the A-direction inner core 27 and the axle sleeve 49, two positioning guide rods 48 and the positioning guide holes are arranged. Slidingly connected in the axial direction, the shaft sleeve 49 is connected with the rod head of the A-direction push rod 26 through the spring on the positioning guide rod 48. When the spring is compressed, the spring is in the shaft sleeve groove;

Abstract

The invention relates to a lock core with a delay triggering device and an antitheft lock containing the same. The lock core comprises an outer core body (19) and an inner core body (21) and is characterized in that the outer core body (19) is respectively provided with a locking device and the triggering device; a clamping rod (9) in the locking device is slidably connected with a locking hole of the outer core body (19) by virtue of a spring (11); the inner core body (21) is provided with a locking hole groove which is correspondingly connected with a rod head at one end of the clamping rod(9) in a locking manner; the triggering device comprises a delay contact (13) and a push rod; the push rod is slidably connected with an inner core hole in the outer core body (19), is axially and slidably connected with the inner core body (21), and is radially connected with the inner core body (21) in a positioning manner; one end of the push rod is connected with a push rod sliding cavity of the inner core body (21) and a key hole, and the other end of the push rod is connected with one end of the delay contact (13); the delay contact (13) is slidably connected with the inner groove of the contact in the outer core body (19); and the inner groove of the contact in the outer core body (19) is communicated with an inner core hole in the outer core body (19). By utilizing the lock core, the delay is controllable, the locking is stable, the unlocking difficulty is large and the antitheft effect is obviously enhanced.

Description

technical field [0001] The invention relates to a lock core with a delay trigger device and an anti-theft lock containing the lock core, belonging to the field of locks for fixing buildings. Background technique [0002] Existing locksets, such as door locks and motorcycle locks, are generally composed of a lock body, a lock cylinder, a transmission mechanism, and a switch device (such as a lock head). , the hole in the lock body is provided with a pin slot corresponding to the position of the pin, and the transmission mechanism is connected with the lock cylinder and the switch device. With the improvement of anti-theft technology, anti-theft locks using electricity, magnetism, sound, light, and passwords have been widely used in doors, bicycles, automobiles, safes, etc., such as using lock cylinder anti-theft technology, the name "anti-theft lock cylinder" , application number CN200910095360.3, a sealing bead and a pressing spring are provided in the lock housing, a clamp...
