Abstract
The utility model provides a self-lock magnetic lock-head which can avoid unlocking due to vibration, comprising a magnetic bolt. The lock-head comprises a self-lock mechanism, and the self-lock mechanism consists of a shell and a flexible bolt limiting post attractable to magnet at the back of the bolt. A positioning mechanism of the bolt limiting post is provided in the shell when the bolt limiting post fit with with the bolt limiter. The self-lock mechanism of the utility model is easy to use and has the function of locking the bolt. Through the bolt limiting post in coordinating with the bolt, the sawtooth of the magnetic bolt would not ungear, the lock pin would not separate from the lock hole, and the lock-head would not open automatically in case of vibration, thereby ensuring the device to fix tightly with the goods.
Description
Technical field
The utility model relates to a kind of tapered end of anti-theft device for commodities.
Background technology
Anti-theft device for commodities is that the antitheft label of article surveillance is arranged on device on the commodity, it generally comprises tapered end, be provided with the magnetic dead bolt in the tapered end, the head of dead bolt is provided with sawtooth or lock pin, normality magnetic dead bolt is subjected to the effect of spring, another of the sawtooth of magnetic dead bolt and anti-theft device for commodities be the lock pin of the engagement on part or magnetic dead bolt another lockhole on part partly of being inserted in anti-theft device for commodities partly, make anti-theft device for commodities be set on the commodity, when commercial articles vending, attraction by the magnetic lockaid gun is unblanked, the sawtooth of magnetic dead bolt breaks away from engagement or lock pin breaks away from lockhole, makes anti-theft device for commodities to take off from commodity.Find in actual applications, might be under vibration environment because of the inertia motion of dead bolt, and tapered end is opened automatically, make anti-theft device for commodities lose antitheft effect.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of self-locking magnetic-type tapered end that prevents that tapered end from opening automatically because of vibrations.For this reason, the utility model is by the following technical solutions: it comprises the magnetic dead bolt, described tapered end also is provided with the self-locking mechanism of dead bolt, described self-locking mechanism comprise shell and set at the dead bolt rear can be by the dead bolt limited post of the activity of attraction, the detent mechanism of dead bolt limited post when also being provided with the dead bolt limited post in the shell and cooperating with dead bolt is spacing.
Owing to adopt the technical solution of the utility model, self-locking mechanism of the present utility model is easy to use, can play the effect of locking to dead bolt, cooperate with the spacing of dead bolt by the dead bolt limited post, when being in vibrations, the sawtooth of magnetic dead bolt can not break away from engagement, lock pin can not break away from lockhole, and tapered end can not opened automatically, guarantees that anti-theft device for commodities is arranged on the commodity securely.
The utility model also provides a kind of above-mentioned detent mechanism that is easy to the processing and manufacturing stable performance, described detent mechanism comprises the steel ball seat that is enclosed within outside the dead bolt limited post, be provided with steel ball in the steel ball seat, described dead bolt limited post is provided with the groove that cooperates with steel ball, described detent mechanism also comprise be enclosed within steel ball seat outer can be inhaled the movable sleeve of answering by magnet, the inner surface of movable sleeve is provided with the cam surface that cooperates with steel ball, described detent mechanism also is provided with the push pedal of moving with the dead bolt limited post, is provided with spring between push pedal and movable sleeve.

The specific embodiment
With reference to attached Fig. 1 and 2.The utility model comprises magnetic dead bolt 1, the utility model also is provided with the self-locking mechanism of dead bolt, described self-locking mechanism comprise shell 2 and set at the dead bolt rear can be by the dead bolt limited post 3 of the activity of attraction, the detent mechanism of dead bolt limited post when also being provided with the dead bolt limited post in the shell and cooperating with dead bolt is spacing.
Described detent mechanism comprises the steel ball seat 4 that is enclosed within outside the dead bolt limited post, be provided with steel ball 5 in the steel ball seat, described dead bolt limited post is provided with the groove 6 that cooperates with steel ball, described detent mechanism also comprise be enclosed within steel ball seat outer can be inhaled the movable sleeve 7 of answering by magnet, the inner surface of movable sleeve is provided with the cam surface 8 that cooperates with steel ball, described detent mechanism also is provided with the push pedal 9 of moving with the dead bolt limited post, is provided with spring 10 between push pedal and movable sleeve.
The dead bolt limited post is provided with the limited step 31 that cooperates with steel ball seat.
With reference to accompanying drawing 1; the head of dead bolt 1 is provided with sawtooth 11; drawing reference numeral 12 is another sawtooth that cooperates with sawtooth 11 on part partly of anti-theft device for commodities; drawing reference numeral 14 is for acting on the spring of dead bolt; dead bolt is provided with the protection and the guiding overcoat 13 of dead bolt outward; it is outer and be connected with it that shell 2 is enclosed within dead bolt overcoat 13, and steel ball seat 4 is sandwiched between the step of dead bolt overcoat 13 and shell 2 inner surfaces and obtains locating, and the inner surface of shell 2 is provided with the limited step 21 of movable sleeve.When self-locking mechanism was unlocked, shown in the first half of Fig. 1, at this moment, dead bolt limited post 3 left dead bolt rear end certain distance, also not spacing between the two cooperation.When self-locking mechanism is locked, shown in the latter half of Fig. 1, at this moment, press push pedal 9, dead bolt limited post 3 moves to dead bolt, spring 10 is subjected to the effect of push pedal, and movable sleeve is also produced pressure, when dead bolt limited post 3 moves to groove 6 aligning steel balls 5, be subjected to cam surface 8 effects of movable sleeve 7 inner surfaces, steel ball is squeezed into groove, the rear end that this moment, dead bolt limited post 3 was run into dead bolt substantially, spacing to it, dead bolt limited post self then invar ball was positioned with cooperating of groove, make tapered end realize self-locking, when being in when vibrations and since the dead bolt limited post stop that the sawtooth of magnetic dead bolt can not break away from engagement, tapered end can not opened automatically, guarantees that anti-theft device for commodities is arranged on the commodity securely.When unblanking, use magnetic lockaid gun 15 to attract from the rear end to unblank, dead bolt limited post 3 is answered by the magnetic force suction, and makes 6 pairs of steel balls extruding of groove, movable sleeve 7 is moved by magnetic attraction backward, steel ball is taken advantage of a situation and is broken away from and the cooperating of groove 6, and dead bolt limited post 3 is moved backward, and releasing is spacing to dead bolt, dead bolt is subjected to magnetic attraction and motion backward, sawtooth 11 breaks away from engagement with sawtooth 12, and tapered end was unblanked successfully by a step, and operation is very easy.
With reference to accompanying drawing 3 and 4, in the present embodiment, change the sawtooth 11 of dead bolt 1 head of previous embodiment into lock pin 16, correspondingly, another of anti-theft device for commodities partly is provided with lockhole 17 on part, and the other parts of present embodiment are identical with previous embodiment.
