Abstract

The utility model discloses a recessive and close-contact type theft-proof bicycle lock. The utility model is characterized in that one side of a lock body with a lock core is provided with a fastening lock body; the lock body with the lock core and the fastening lock body are connected into integration by fastening screws arranged in the fastening lock body; a fastening opening is arranged between the lock body with the lock core and the fastening lock body; the lock body with the lock core is provided with a deep hole capable of containing a lock ring head. Even the lock ring of the utility model is broken, the broken lock body is firmly fastened on the bicycle body unable to be removed; if the lock body is provided with an alarming device, the broken lock body on the bicycle body can send out an alarm sound.

Description

Stealthy close-fitting anti-theft vehicle lock

The utility model relates to the technical field of lock, the close-fitting anti-theft vehicle lock of specifically a kind of stealth, and it has reports to the police and two major types of not reporting to the police.

Though the lock kind that is used for bicycle, power assist vehicle and motorcycle of Xiao Shouing is a lot of in the market, but the stealthy lock that is fastened on the vehicle body was not seen, the lock of band burglar alarm also seldom appears on the market, a kind of burglar alarm lock is arranged on the market, but the lock body of this lock is easy to remove from vehicle body.

The purpose of this utility model is to provide a kind of stealth close-fitting anti-theft vehicle lock, and it can be removed attached to being difficult on the vehicle body securely.

The technical solution of the utility model is achieved in that stealthy close-fitting anti-theft vehicle lock, it mainly comprises the lock body that has lock core, can throw off and fixing lock ring with this lock body, it is characterized in that: establish a fastening lock body in lock body one side that has lock core, the lock body and the fastening lock body that have lock core link into an integrated entity by the holding screw of establishing within it, between lock body that has lock core and fastening lock body, be provided with fastening port, in having the lock body of lock core, be provided with the deep hole that can hold the lock ring head.

Even the utility model is after lock ring is broken, incomplete lock body still is fastened on firmly on the vehicle body and can't removes, if warning device is housed on lock body, then can send chimes of doom in the lock body of incompleteness on the vehicle body.

Fig. 4 is the structural representation of the another embodiment of the utility model

The utility model will be further described below in conjunction with drawings and Examples.

The utility model mainly comprises the lock body 2 that has lock core 4, can throw off and fixing lock ring 3 with this lock body, this lock ring 3 also comprises the lock ring head 7 that can match with lock core 4, it is different from prior art: establish a fastening lock body 1 in lock body 2 one sides that have lock core 4, the lock body 2 and the fastening lock body 1 that have lock core 4 link into an integrated entity by the holding screw of establishing within it 5, between lock body 2 that has lock core 4 and fastening lock body 1, be provided with fastening port 9, the stealth of this lock can be packed on the vehicle body by this fastening port 9, in the lock body 2 that has lock core, be provided with the deep hole 6 that can hold lock ring head 7, one end of lock ring 3 and fastening lock body 1 are for fixedlying connected, and the other end of lock ring 3 is that lock ring head 7 is being connected of can throwing off by lock core with the lock body 2 that has lock core 4; The lock body 2 and the fastening lock body 1 that have lock core 4 in an embodiment link into an integrated entity by two holding screws of establishing within it 5, in the lock body 2 that has lock core 4, be provided with two deep holes 6, adorn a lock ring head 76 mouthfuls of deep holes, adorn a lock ring head or silently 86 mouthfuls of another deep holes, this silently 8 makes the lock ring head, after being packed in this lock on the vehicle body, 6 mouthfuls of deep holes load onto silently 8 therein again, unblank the back in the deep hole 6 lock ring head 7 and silently 8 can throw off, after locking, lock ring head in the deep hole 6 reaches and silently 8 can not extract, and the deep hole mouth was shut and the lock body on the vehicle body can't be removed after lock ring head 7 was locked; Two deep holes 6 are arranged on the lock body 2 that has lock core 4 in the specific embodiment, two lock ring heads 7 of lock ring 3 all with the lock body 2 that has lock core 4 on two deep holes 6 be connected (fit structure of this lock core and lock ring head is a prior art) for throwing off, latter two lock ring head 7 of locking all can not be extracted, two deep hole mouths 6 are all shut, and the lock body that is contained on the vehicle body can't be removed; Another embodiment of the present utility model is equipped with warning device in fastening lock body 1, this warning device is mainly by triode, controllable silicon, acoustical generator and power supply are formed, the emitter stage that is specially triode G1 connects positive source, its colelctor electrode and base stage connect base stage and the colelctor electrode of triode G2 respectively, the emitter stage of triode G2 connects the trigger electrode of controllable silicon SCR, the anode of controllable silicon SCR connects positive source, its negative electrode connects the end of acoustical generator R, the other end of acoustical generator R is connected with the negative pole of power supply, and the base stage of the colelctor electrode of triode G1 and triode G2 is connected with the negative pole of power supply through lead L; During lead L was laid in lock ring 3 in an embodiment, acoustical generator can be language machine of the prior art, sounder, buzzer or other pronunciation equipment.

The course of work of the warning device among another embodiment of the utility model is, when in running order, electric current enters from the emitter stage of triode G1, flow out through its base stage and colelctor electrode, enter colelctor electrode and the base stage of triode G2 respectively, emitter stage through triode G2 flows out again, the silicon controlled trigger current is provided, when the base stage of the colelctor electrode of triode G1 and triode G2 because lead and power cathode when being in short-circuit condition, triode G2 and triode G1 all are in cut-off state, the emitter stage no current of triode G2 flows out, controllable silicon is because the not conducting of triggerless electric current, acoustical generator also no current is not worked, when lock ring is broken, when being open wires, triode G1 and G2 conducting, the current trigger controllable silicon conducting that triode G2 emitter stage flows out, at this moment electric current enters from the silicon controlled anode, flow out from negative electrode, the acoustical generator electric current is provided, and acoustical generator sends chimes of doom at once, because controllable silicon has auto-lock function under DC condition, so again the lead short circuit can not be stoped the controllable silicon conducting, acoustical generator is still ceaselessly reported to the police all the time.
