Row engaging, the needle body are fixed by spring and magnetic metal sliding block.The metal block is provided with arc-shaped close to needle body side
Groove, cradle needle body；The radian that the metal block encircles needle body is less than 180 degree.The commercial anti-theft label, inner utilization
Metal block substitutes traditional steel bowl, three hole steel cores and steel ball, greatlys save cost, so that the process of assembling anti-theft tag subtracts
Less, efficiency improves, and has saved the cost of anti-theft tag on the whole.
For another example, application number 200610062346 provides a kind of binding-band type wine bottle anti-theft and its dedicated lockaid gun, antitheft
Device includes shell, bandage and is installed on the intracorporal EAS anti-theft tag of the shell, and one end of bandage is connect with shell, on the shell
Bandage inlet and outlet for the disengaging of bandage free end are set, and bandage backstop is arranged in close bandage import and export in shell, this is tied up
Band backstop includes a self-locking centering block and spring, and the open keyhole passed in and out for lockaid gun shift fork is arranged in the housing sidewall.It opens
Lock device includes shell, and lower casing surface has one for accommodating the cavity of above-mentioned wine bottle guards against theft device upper casing, is pivotally connected one between upper and lower shell
Shift fork via hole is arranged on the shell for a shift fork.The alarm uses dedicated lockaid gun, stirs self-locking centering block by shift fork and turns
It is dynamic, alarm is releasably released from bottle with bandage, release method is laborsaving, safe and reliable.
Summary of the invention
Present invention aims at: a kind of on & off switch controlled by magnetic force is provided, anti-theft effect is improved.
The object of the invention is solved by following technical proposals: a kind of magnetic switch key, including magnetic unlocking part and latch portion
Part, lock buckling part are engaged with the fixation tooth being fixed on locked object part by buckle or tooth form, in which:
The magnetic unlocking part is the magnet ring with centre bore；
One shell, at least front opening；
The lock buckling part is fastened into slide block assembly, the slide block assembly quilt by sliding block one and the mutually sliding of sliding block two
Inside the shell, slide block assembly can limitedly slide back and forth inside the shell, and slide block assembly is supported by spring, wherein described for installation
Sliding block one be toothed portion sliding block, make one teeth portion of sliding block that can stretch out shell along the front opening of shell, and with fixed tooth engagement；
The sliding block two is the sliding block of carrying magnetic iron core, and there is pressure spring in magnetive cord bottom, there is a bayonet or limiting slot on the shell,
When locking, magnetive cord can be supported by pressure spring and protrude into bayonet or limiting slot；
When unlocking, the central aperture magnetive cord of magnet ring, the down thrust of central hole is pressed down magnetive cord,
Leave bayonet or limiting slot, when magnetive cord by sidesway to magnet ring entity part when, under magnetic masterpiece, magnetive cord, which drives, to be slided
Block assembly integrally continues sidesway, and the buckle or tooth form of the teeth portion and the fixation tooth on locked object part that make sliding block one are detached from, and completes out
Lock.
The working principle of the invention is:
When locking state, in slide block assembly, sliding block two is equipped with a magnetive cord, and magnetive cord is supported by pressure spring, makes its card
It being buckled in the bayonet or limiting slot of shell, slide block assembly cannot be moved forward and backward, meanwhile, under the action of the spring, the teeth portion of sliding block one
Stretch out shell and fixed tooth engagement；
Magnetive cord when only being acted on by pressure spring, maintenance support in bayonet or limiting slot, only by magneticaction when contract
Back out bayonet or limiting slot.
When unlocking, it is directed at magnetic core using magnet ring, the thrust of magnet ring centre bore pushes magnetive cord, and makees in spring
With, leave it at the bayonet or limiting slot of shell with movable slider two, it is mobile to the direction far from fixed tooth, when magnetive cord connects
When the entity part of nearly magnet ring, under magnetic attraction effect, slide assemblies are driven further to move in the direction, until one tooth of sliding shoe
Portion and fixed tooth are detached from.
On the basis of above scheme, the side of the sliding block two is equipped with shifting block, and shell is open with respect at shifting block, and shifting block is stretched
Shifting block is stirred in shell out, front and back, slide block assembly can be driven to be moved forward and backward by band movable slider two, with anti-jamming.
On the basis of above scheme, there is a spring between sliding block one and sliding block two, which supports sliding block one
Inner wall, the other end support the side wall of sliding block two, when unlock when, the central aperture magnetive cord of magnet ring, central hole it is downward
Thrust is pressed down magnetive cord, leaves bayonet or limiting slot, and pushes two sidesway of sliding block under the action of the spring.
On the basis of above scheme, the sliding block one is equipped with stepped part, when sliding block two snaps on sliding block one, the rank
Terraced portion extends to the tail portion of sliding block two, is buckled on sliding block two under the action of the spring.
On the basis of above scheme, when the sliding block two is with one snapping of sliding block, it is equipped with groups of springs in the tail end of sliding block two,
Groups of springs one end is supported with sliding block two, and the other end is supported with outer casing inner wall.Position-limiting action is played to the sliding of slide block assembly.
To guarantee that magnetive cord is mobile to the direction far from fixed tooth under magneticaction.On the basis of above scheme, institute
The center line of the magnet ring center line and magnetive cord stated is staggered, and keeps the center line of magnetive cord inclined to the direction far from fixed tooth
From.
On the basis of above scheme, the magnetive cord is cylindrical iron block.
The present invention has the advantages that only can realize unlocking using specific magnet ring of the invention, anti-theft performance is improved；Together
When, manual switch function prevents also playing the role of dual fail-safe when component accident.
