Description

The button anti-theft device

Technical field

The present invention relates to the anti-theft device field, relate in particular to a kind of button anti-theft device.

Background technology

Existing anti-theft device is generally machinery control, and is generally single key lock or digital phase-locking, and after key loss or the self-locking of digital phase-locking mistake, release comparatively bothers.

Summary of the invention

The object of the invention is to overcome the problems referred to above, provide a kind of have concurrently key lock and digital phase-locking function, digital phase-locking by electrical control, prevent the button anti-theft device of wrong self-locking.

To achieve these goals, the technical solution adopted in the present invention is: the button anti-theft device comprises: a housing comprises a shell body and an inner housing; One key groups is arranged on the housing, comprises a cover plate, some digital buttons and a shift knob; And a latch hook, be arranged at the housing top, it is characterized in that: the single-chip microcomputer that described key groups bottom is provided with control element, is connected with control element, press some digital buttons and press shift knob and can open latch hook.

Aforesaid button anti-theft device, the edge of the described shell body coating inner housing that bends inwards.

Aforesaid button anti-theft device, described anti-theft device also comprises a dust excluding plate, is articulated in the cover plate lower end of inner housing lower end or key groups.

Aforesaid button anti-theft device is provided with dividing plate between described key groups and the housing.

Aforesaid button anti-theft device, described shell body sidepiece is provided with key lock, is embedded key in the key lock, and key lock is connected with swivel plate, and the end of swivel plate connects shell fragment, and described shell fragment is sticked in the latch hook bayonet socket of latch hook.

Aforesaid button anti-theft device, described digital button are connected the lower end and are connected control element with shift knob, single-chip microcomputer is connected with the electronic rotation parts, and the electronic rotation parts are rotatably connected with shell fragment again, and described shell fragment is sticked in the latch hook bayonet socket of latch hook.

Aforesaid button anti-theft device, described key groups also is provided with reset button.

Key is inserted key lock, screw key, the rotation of driven rotary plate, and then the rotation of band spring plate make the shell fragment that is sticked in the latch hook bayonet socket originally leave the latch hook bayonet socket, and latch hook is opened; Press some digital buttons and shift knob, control element is inputted single-chip microcomputer with key information, and single-chip microcomputer is according to pre-set programs control electronic rotation parts, the rotation of electronic rotation parts band spring plate, make the shell fragment that is sticked in the latch hook bayonet socket originally leave the latch hook bayonet socket, latch hook is opened.Reset button is used for digital button is carried out zero clearing.

The beneficial effect that the present invention has is: have concurrently key lock and digital phase-locking function, digital phase-locking by electrical control, prevent wrong self-locking.
