The purpose of this utility model provides a kind of burglar alarm mortise lock that can prevent effectively that bicycle or motorcycle bolt from being cut off and losing.

The further purpose of the utility model is can in time report to the police when unblanking with non-original key.

For reaching above-mentioned purpose, the following technical scheme of the utility model: a kind of burglar alarm mortise lock, comprise lock housing and be contained in lock housing interior lock body and U-shape lock bar, lock core and billiard mechanism are housed in the lock body, the bolt jack is arranged on lock housing and the lock body, battery and speech synthesizer are housed on the lock body, the loudspeaker that is electrically connected with speech synthesizer is housed in the lock housing, there are some phonate holes at the corresponding loudspeaker of lock housing position, in the slotted hole in the bolt drag-line and spring are housed, spring end is provided with movable contact, is provided with stationary contact in the bolt jack.

Spring in the bolt slotted hole has big compression spring and little spring two parts, the joint portion is connected by a catch between the two, terminal riveted joint has a sloping platform pin near bolt on the bolt wall, the sloping platform of sloping platform pin stretches out the slotted hole inwall slightly, stationary contact in the bolt jack is a metal cylinder, in the jack of cylinder top plastic roof with holes is housed.

One insulation pellet shot from a slingshot also is housed before the inherent metal pellet shot from a slingshot in the pellet shot from a slingshot hole in the lock body, has groove, the metal patch is housed in the groove near in the lock body of metal pellet shot from a slingshot.

Lock housing is spirally connected by the two parts that are processed with internal and external threads respectively and forms, and has the groove and the silk hole of mounting plate on the lock housing.

Because the utility model is equipped with battery, speech synthesizer in lock body, between battery and speech synthesizer, seal in an alarm switch that forms by the stationary contact in the bolt jack of movable contact in the bolt and lock body, alarm switch is in off-state at ordinary times, and bolt is in case cut off, spring force in the bolt slotted hole makes movable contact contact with the interior stationary contact of jack, battery and speech synthesizer are connected, sent chimes of doom, the burglar is struck fear into and abandon car thought steathily by loudspeaker.In addition, different because of it when unblanking with the original key profile of tooth with non-original key, when the peak of non-original key tooth is higher than the original key peak, cause the metal pellet shot from a slingshot and be loaded on the interior metal patch of lock body to contact, connect circuit and cause warning.

Further specify the utility model below in conjunction with accompanying drawing and by embodiment:

Fig. 1 is the utility model structural representation of (not comprising the U-shape lock bar);

Fig. 2 is the A-A generalized section of Fig. 1;

Fig. 3 is the vertical view of Fig. 1;

Fig. 4 is the structural representation of U-shape lock bar and connector thereof.

Embodiment; Lock housing comprises the steel lock housing 2 that has externally threaded steel lock housing 1 and have internal thread, the steel lock housing is provided with plastic latch shell 5 outward, plastics lock body 4 is housed in the steel lock housing, metal lock core 3 and billiard mechanism are housed in the lock body 4, billiard mechanism comprises the metal pellet shot from a slingshot 9 that is contained in the lock marble hole, insulation pellet shot from a slingshot 11, spring 12 and compressing tablet 13, having groove near in the lock body of metal pellet shot from a slingshot 9, the adjustable metal patch of being made up of several sheet metals 10 is housed in the groove, and the distance of metal pellet shot from a slingshot top and metal patch 10 should guarantee can not make when original key inserts metal pellet shot from a slingshot 9 tops and metal patch 10 to contact.Fixed contact metal cylinder 16 is equipped with in bolt jack 30 bottoms, and cylinder 16 outer walls are with spring 15, and plastic roof with holes 14 is housed in the jack above cylinder 16.Drag-line 21 and big compression spring 24 are housed in the slotted hole 28 in the U-shape lock bar, and spring 24 ends have a catch 19, and little spring 18 is connected on the catch 19, and its end is provided with a stationary contact 17.Terminal riveted joint has sloping platform pin 20 near bolt on the bolt wall, and its sloping platform stretches out the slotted hole inwall slightly.Drag-line 21 front ends are fixing by alignment pin 22.Battery 8 and speech synthesizer 7 are housed in lock body, loudspeaker 6 is housed in the lock housing, there are some phonate holes 23 at the corresponding loudspeaker of lock housing position.Form warning device by battery 8, speech synthesizer 7 and loudspeaker 6,, no longer provide physical circuit figure and detailed description at this because warning device is a known technology.

After the U-shape lock bar inserts lockhole, the big compression spring that is installed in the bolt is controlled by drag-line, after the U-shape lock bar is cut off, drag-line is cut off simultaneously, big compression spring is pushed ahead rapidly by a face of cutting nippers, and catch was pushed away sloping platform, and the little spring before the catch can be changed into compressive state by normal extension, little compression spring is promptly pushed movable contact to fixed contact, thereby the closed warning circuit of connecting of the alarm switch that is made of movable contact and fixed contact is reported to the police.Even the thief pulls out big compression spring, because catch is stopped that by sloping platform under the situation that can not pull little spring and cable wire, can not causing reports to the police stops.When unblanking with non-original key, different because of the shaped as key bit height, when the peak of non-original key tooth is higher than original key tooth peak, cause that the metal pellet shot from a slingshot contacts with the adjustable metal patch, makes switch closure be reported to the police by warning device.

Lock housing of the present utility model is threaded by two parts, can make like this when dead battery that to change battery convenient, when changing battery, opens lock housing 1 and lock housing 2, changes screw on behind the battery lock housing 1 and lock housing 2 and gets final product.V-type fixed head 26 is housed at last, be anchored in the screw 25 with screw again, fixedly the junction plate of lock body is anchored on screw and is contained on bicycle or the motorcycle in the screw 27 afterwards, load onto U-shape lock bar and fixed support 29 at opposite side, when lock was not opened, the screw even the thief dismantles in the screw 27 also can't remove " V " type fixed head, can not destroy warning device, thereby warning work can normally be carried out.
