Description
The utility model relates to lockset, and especially a kind of its bolt can send the burglar alarm bar lock of chimes of doom when being cut off by the people.
Existing lock, general by the lock body with ball lock head, an end links to each other with the lock body and the other end has a bolt composition of termination that can insert the ball lock head of described lock body.The bolt of this class bar lock can bending and length suitable, can be used as the protective device of the article that bicycle, tricycle, trolley, motorcycle and this class of travelling lodge need move.But the maximum deficiency of bar lock is that its bolt is easy to be cut off by the people.Cause lockset to damage, cause article lost.
The purpose of the utility model is the shortcoming that is latched at existing bar, and the burglar alarm bar lock of chimes of doom can be provided when providing a kind of its bolt to be cut off by the people.
The utility model purpose can realize like this: a kind of burglar alarm bar lock, comprise the lock body, be arranged in the ball lock head of lock body, and one one end links to each other with described lock body and the other end has the bolt of the termination that can insert the ball lock head in the described lock body, it is characterized in that in the bolt of described burglar alarm bar lock the through hole that connects along its core being arranged, comprise in the through hole that an one end links to each other with described termination and the other end stretches into the drag-line in the described lock body; By the sounding alarm device of forming by power supply, speech synthesizer and the loudspeaker that links to each other with this speech synthesizer output, also have in the described lock body by the alarm switch that fixed contact and movable contact constituted that can be in contact with one another and when contacting, can connect the power path between described power supply and the described speech synthesizer; Described movable contact links to each other with drag-line in stretching into described lock body, has between this movable contact and the lock body inwall to be placed in the compression spring of described drag-line to guarantee that this drag-line makes movable contact contact with described fixed contact when being cut off; The aperture that described lock is interlinked to the outside in having on one's body.
Described scheme mainly is to have set up the sounding alarm device in the lock body of existing bar lock, has designed by drag-line control that is arranged in bolt and the alarm switch that is made of movable contact, fixed contact and compression spring.This structure can be when the bolt of bar lock be cut off by the people, and drag-line is also cut off simultaneously because drag-line is cut off, and closed naturally by the alarm switch of its control, the sounding alarm device sends chimes of doom thereupon, makes by the article of bolt-lock to avoid losing.
More reliable for the action that makes the alarm switch in the described scheme, a gathering sill that extends to described fixed contact both sides can also be set in the compression spring both sides in the described lock body.This gathering sill can guarantee to compress spring and exactly movable contact be pushed to described fixed contact when described drag-line be cut off.
In sum, the utility model is owing to the alarm switch that is provided with the sounding alarm device and is controlled by the drag-line that is arranged in bolt, not only overcome the shortcoming that prior art can not be reported to the police, and has a protection function of existing bar lock, can be used as the protective device of this class mobile article of bicycle, tricycle, motorcycle and luggage, reached the purpose of this utility model.
The utility model has following accompanying drawing, and accompanying drawing has been put down in writing an instantiation of the present utility model.
Below in conjunction with example the utility model is described.
In the example (referring to accompanying drawing):
In the lock body 1 ball lock head 2 is arranged, it has aperture 17.The bolt 10 1 ends other end that links to each other with lock body 1 has and can insert the termination 3 of locking ball lock head 2 in the body 1, and it comprises cable wire 13 and plastic wrapper 19, and its core has through hole 11.It in the through hole 11 drag-line 12.Drag-line 12 1 ends link to each other with termination 3, and the other end stretches into lock body 1 and links to each other with movable contact 8.9 are the compression spring.15 is gathering sill.6 is support, and it has installed fixed contact 7 and the circuit board 5 of speech synthesizer is housed.16 is power supply (pond), and 4 is loudspeaker, and 21 is keyhole.Constitute alarm switch by movable contact 8, fixed contact 7 and compression spring 8 in this example, it is gone here and there between the power path of power supply and speech synthesizer; Constitute the sounding alarm device by power supply (pond), speech synthesizer and loudspeaker.Because the sounding alarm device is a known technology, does not provide physical circuit.
The example course of work: when bolt 10 was cut off, drag-line 12 was cut off simultaneously, and movable contact 8 advances and contacts with fixed contact 7 at the promotion lower edge gathering sill 15 of compression spring 9, and speech synthesizer gets electric work, and loudspeaker 4 sends chimes of doom ...
