Fig. 1 to Fig. 2 shows a kind of anti-theft lock with alarm Trigger Function according to the preferred embodiment of the present invention
Structure diagram, should with alarm Trigger Function anti-theft lock include lock core shell 1, lock core 2, snap ring 3, bayonet lock 4, the second bullet
Spring 5, gland 6, locking member 7, trigger switch 8 and ejector pin 9.With reference to figure 1, the front end of lock core shell 1 is provided with the stepped hole of three ranks,
Aperture reduces step by step from top to bottom.The rear portion inlay card of lock core 2 is in the last one hole of the stepped hole of lock core shell 1, before lock core 2
Portion extends to the front end of lock core shell 1, can normally be unlocked with key.Snap ring 3 is rotatably sheathed on lock
In the interstitial hole of the stepped hole of core shell 1, and snap ring 3 is rotatably sheathed on the front end of lock core 2 simultaneously.With reference to figure 2,
The front end face of snap ring 3 is recessed with one first card slot 31, and the side wall of snap ring 3 is recessed there are two the second card slot 32, and the side wall of snap ring
It is further opened with a snap ring through-hole 33 communicated with the endoporus of snap ring 3.Preferably, two the second card slots 32 are symmetrically recessed in snap ring
On 3 side wall, and line is parallel to the arc groove of the center line of snap ring 3 centered on the second card slot 32.Snap ring through-hole 33 is distributed in two
The centre of a second card slot 32, the first card slot 31 are distributed in the opposite of snap ring through-hole 33.Lock core shell 1 is provided with one and snap ring through-hole
33 corresponding lock core housing hole, and the side of sidewall portion of lock core 2 on be provided with one and 33 corresponding lock core hole of snap ring through-hole, normal use
When, lock core hole, snap ring through-hole 33 and lock core housing hole are located along the same line.
With continued reference to Fig. 1, bayonet lock 4 includes the first pin 41, the second pin 42 and third pin 43, and the first pin 41 is lived
It is dynamic to be sheathed in the lock core hole of lock core 2, one end of the second pin 42 be movably set in lock core hole and with 41 activity of the first pin
Contact, the other end of the second pin 42 are movably set in snap ring through-hole 33, and one end of third pin 43 is movably set in snap ring
In through-hole 33 and with the other end movable contact of the second pin 42, and the other end of third pin 43 is lived by one first spring 44
Dynamic to be sheathed in the lock core housing hole of lock core shell 1, the intensity of third pin 43 is less than the intensity of the second pin 42, can be third pin
Column 43 is identical with the size of the second pin 42, and the diameter of third pin 43 is less than the diameter of the second pin 42；Alternatively, the second pin
The material of column 43 is smaller than the hardness and rigidity of the material of third pin 43.In the effect of the first spring 44 during normal use
Under, it is constant that three pins are maintained at current state.Mating to be provided with one on the key right with the first pin 41 being carried out with lock core 2
The tooth form answered, when opening the lock with the key, corresponding tooth form can be by the first pin 41 the second pin 42 ejection lock core completely
Except hole so that lock core can under the action of key normal rotation.
With continued reference to Fig. 1, gland 6 be set in a manner of it can dismantle bolt the stepped hole of lock core shell 1 most before
In one hole, and gland 6 is covered on the front end face of snap ring 3, to prevent snap ring 3 from moving axially.Gland 6 is provided with one and card
The 31 corresponding locking hole of the first card slot of the front end face of ring 3, the forepart of locking member 7 are set to locking hole by a second spring 5
It is interior, and in normal state, the rear portion of locking member 7 is acted against in the first card slot 31 under the action of second spring 5, so that snap ring
3 are connected with head cover 6, and snap ring 3 is rotated with lock core 2 during preventing from normally unlocking.Preferably, locking member 7 is steel ball
The decorative pearl on top of an official cap, preceding part are located in locking hole, and rear part is in the first card slot 31.
Trigger switch 8 uses normally opened microswitch for one, and when no external force acts on, the inside shrapnel of trigger switch 8 will
Contact point ejects outward, and the two of trigger switch 8 electrode is separated at this time；When there is external force effect, external force is acted on so that touching
Head is put to be moved, and push internal shrapnel to the inside of trigger switch 8, so as to connect the contact of the two of trigger switch 8 electrode interiors
It is logical.Trigger switch 8, which is bolted, to be set on lock core shell 1, and lock core shell 1 is provided with a contact point for being located at trigger switch 8
Sliding slot between snap ring 3, ejector pin 9 are set in a manner of it can slide in the sliding slot of lock core shell 1, and one end of ejector pin 9 abuts against
The contact point of trigger switch 8 is acted against in the other end of the side wall of snap ring 3, and ejector pin 9, and under normal condition, ejector pin 9 is contact point
It is headed into the inside of trigger switch 8, so that the contact of 8 two electrode interiors of trigger switch keeps connecting, two of trigger switch 8
When electrode is in connection, warning device is not alarmed, and when two electrodes of trigger switch 8 disconnect, warning device is just alarmed.
In normal state, ejector pin 9 is withstood in the contact point of microswitch 8 lock core 2 always, makes two of trigger switch 8
Electrode interior contact connects, and no alarm signal exports at this time.And gland 6 is connected as a single entity by locking member 7 and snap ring 3, snap ring 3 is not
It can rotate, normal operating can be carried out to lock by correct key.When lock core 2 is rotated under non-matching key by violence,
Locking member 7 can be jacked up upwards by force even to be damaged, so as to unlock the locking between gland 6 and snap ring 3, and due to third pin
The intensity of column 43 is less than the intensity of the second pin 42, and third pin 43 can be unlocked prior to 42 fracture damage of the second pin so as to solve
Locking between core shell 1 and snap ring 3, snap ring 3 just can rotate in lock core shell 1.When violence reaches it is sufficiently large when, due to second pin
The stuck effect of column 42, lock core 2 can drive snap ring 3 to form rotation, when snap ring 3 turns to the second card slot 32 and ejector pin 9 to timing,
Ejector pin 9 will be receded into the second card slot 32 on snap ring 3, and the contact point of trigger switch 8 resets, and two electrodes disconnect generating
Alarm signal exports, so as to which warning device be made to alarm.
The present invention increases snap ring 3, bayonet lock 4 and ejector pin 9, when lockhole is agitated by violence, snap ring on lock core shell 1
3 rotate together with lock core 2, and ejector pin 9 is returned in the second card slot 32 of snap ring 3, and 8 disconnecting circuit of trigger switch is so that alarm fills
It puts and sends out alarm, the structure is reliable, and antitheft sensitivity improves, and each parts are easy to manufacture, at low cost, is suitble to batch
Production.The present invention can greatly improve theftproof lock safety, and compact overall structure, sturdy and durable, applied widely.Separately
The outer present invention is not limited to other lockings such as antitheft door, safety cabinet, national treasury and environmentally can also be used.
The description of the aforementioned specific exemplary embodiment to the present invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explain that the specific principle of the present invention and its reality should
With so that those skilled in the art can realize and utilize the present invention a variety of different exemplary implementations and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
