Description
The utility model belongs to a kind of vehicle anti-theft warning device, particularly a kind of bicycle anti-theft alarm lock.
As everyone knows, China is a bikedom, and bicycle uses quite universal in every family.But the stolen incident of the bicycle of Fa Shenging usually makes that car owner's worry is heavy voluntarily.In the known technology, various anti-theft devices being arranged, wherein is to install an alarm on bicycle additional comparatively widely.But this alarm since be subjected to installation site, user to operate separately alarm particularly the alarm element subject to the restriction that auto theft person destroys, seldom have the car owner to use so far.
Task of the present utility model provides a kind of existing ordinary bicycle lock function alarm effect and good, the easy to use bicycle anti-theft alarm lock of preventing destructing performance again.
For solving above-mentioned task; the solution that the utility model adopts is: the alarm element is all packed in the bicycle lock lock case; box controlling device for doors and loudspeaker protector are set on lock body; one collision block is set on the lock body snap close; collision block can just in time be pressed onto on the warning circuit power switch with screw-home movement, with control warning circuit power switch.During use, this lock is installed on the ordinary bicycle lock position, can control lock simultaneously by the bicycle lock key, the dismounting of alarm circuit power switch and box controlling device for doors.
Above-mentioned box controlling device for doors is by the box door closure, be fixed on the frame of deciding on the box door closure, decide the bolt in the frame, form with group bar of deciding the frame two ends and spring, dialling bar is fixed on the lock core, decide frame, have some coaxial screws on bolt and the box door closure, and decide frame screw aperture less than the screw aperture on bolt and the box door closure, the box controlling device for doors is fixed on the lock bottom plate with bolt by these screws, when lock is sealed, lock core rotation drives dials bar and the bolt pressuring spring is entered decide in the frame, cause the screw dislocation of bolt and box door closure, when lock is opened, lock core drives group bar and leaves bolt, spring ejects bolt, makes screw coincidence on bolt and the box door closure, and the car owner can disassemble the box controlling device for doors with screwdriver.
Loudspeaker protector is made up of the shell that goes out soundboard, loss prevention plate and wrap in other position lock body of loudspeaker itself that is installed in loudspeaker horn mouth bottom; go out between soundboard and the loss prevention plate and leave the gap; going out soundboard has some senders near the loudspeaker horn port area, and wrapping on the shell wall of gap outside has some acoustic grooves to guarantee that loudspeaker sound can spread out of by sender, gap, acoustic groove.
Owing to adopted in the above-mentioned solution alarm element is all packed in the bicycle lock lock case; be provided with box controlling device for doors and loudspeaker protector on the lock body; and warning circuit power switch control; alarm and bicycle lock are organically combined; easy to use, preventing destructing performance is good.
Below in conjunction with embodiment the utility model is further described in detail:
Fig. 1 is the utility model embodiment Facad structure schematic diagram.
Fig. 2 is the sectional drawing of structural representation shown in Figure 1 along the A-A line.
Fig. 3 is the utility model embodiment box controlling device for doors structural representation.
Fig. 4 is the sectional drawing of box controlling device for doors shown in Figure 3 along the B-B line.
Above-mentioned accompanying drawing shows structure of the present utility model from different perspectives.All Alerts device element is contained in the shell of whole lock bodies made of iron (1); battery case (5) that is fixed on base plate (19) and the box controlling device for doors that pastes mutually with battery case are equipped with in lock body (1) top; in the middle cavities alarm circuit plate (11) is installed; loudspeaker (15) and loudspeaker protector; the bottom is the snap close (3) of bicycle lock, and lock core (20) etc. are in the front of lock body (1).
