Detailed description of the invention

Embodiment 1:

Seeing Fig. 1-Fig. 5, this utility model provides a kind of Antitheft zipper, including pull head 1, block 2, Pulling-on piece 3 and horse hook 4, and described block 2 is fixed on the upside of described pull head 1, and described pulling-on piece 3 is set in In described block 2, stating horse hook 4 in the form of sheets, the upside of described pull head 1 offers horse and hooks groove 9, described Horse hooks one end of 4 and is hinged in described block 2, and described horse hooks the other end of 4 and is positioned at described horse hook groove 9 In, described horse hooks the other end of 4 and coordinates with the slot 10 in described pull head 1.

Specifically, pull head 1 is through fastener chain, and fastener chain is made up of some sprockets, adjacent Two pairs of sprockets between constitute a slot 10, in normal state, horse hooks the other end of 4 through horse Hook groove 9 and coordinate with the slot 10 of horse beneath trenches (popular says, it is simply that horse hook 4 the other end with It is stuck in slot 10), Gu in this condition, people pull the slide fastener (bearing of trend along fastener chain Force) time, due to horse hook 4 the other end be stuck in slot 10, just cannot pull slide fastener (Fig. 1 with Fig. 4 shows).

And when being applied on knapsack by this utility model, thief cannot open draw by pulling open mode normally Chain, so also the article in knapsack cannot be stolen out, additionally, thief is when pulling slide fastener, inevitable Slide fastener can be torn by bigger strength, and tear the process of slide fastener, the knapsack that user is experienced will be made Vibrations (tearing the vibrations that slide fastener is brought), will later check knapsack, such thief just cannot continue Continue surreptitiously.

And when being opened by slide fastener, need to lift horse hook 4, say, that need to utilize pulling-on piece 3 Catch on horse hook 4 to pull up so that horse hooks 4 and separates with slot 10, keeps the strength that this is forward gone up, Straining beam is applied the strength (bearing of trend along straining beam chain exerts a force) pulling slide fastener simultaneously, this Sample just can open or close slide fastener normally.And thief is when using same method to open slide fastener, due to suitable Upwards apply a strength so that horse hook 4 separates with slot 10, user will necessarily be made to feel shoulder Pressure lighten, this just reminds user to have people opening slide fastener, and such user will check knapsack, Gu the larceny (Fig. 2 and Fig. 5 shows) of thief just can be hindered.

Certainly horse hooks 4 can be that elastic horse hooks 4, say, that when without external force, horse hooks 4 under the elastic force effect of itself, and horse hooks the other end of 4 and can move down always, until horse hook 4 is another One end coordinates with slot 10, and the process lifting horse hook 4 in pulling-on piece 3 phase overcomes horse to hook 4 the most exactly The elastic force of body.

Embodiment 2:

Relative to embodiment 1, horse hook 4 needs not be elastic horses hook 4, and (horse of common rigidity hooks 4 also Can), embodiment 2 is relative to a shell fragment 6 more than embodiment 1, and shell fragment 6 is arranged on horse and hooks 4 And between block 2, the upside of described shell fragment 6 contacts with described block 2, the lower end of described shell fragment 6 with Described horse hooks the middle part contact of 4.

The effect of shell fragment 6 is in order to lasting hooks 4 one downward power of applying to horse, to ensure that horse hooks 4 The other end can be stuck in slot 10.

In like manner, when user needs to open slide fastener (slide fastener), only need to upwards lift pulling-on piece 3, And pulling-on piece 3 hooks 4 with horse and contacts, overcome the elastic force of shell fragment 6, horse hook 4 is lifted, and then horse is hooked The other end of 4 separates with slot 10.

Following improvement also can be made for embodiment 1 and embodiment 2:

One end of described horse hook 4 is hinged on the medium position of described block 2, and the middle part of described block 2 is also Being fixed with snap fit 5, described horse is hooked one end of 4 and is hinged in described block 2 by described snap fit 5.

The setting of snap fit 5 in the middle part of block 2, can be divided into district 8, hollow section 7 and Ma Gou before and after block 2, Wherein horse hook 4 is positioned at Ma Gou district 8.

It is to say, when people want slide fastener, need to first ensure that the collar of pulling-on piece 3 is positioned at Ma Gou district 8 In, and then could upwards carry pulling-on piece 3 ability, slide fastener, and if the collar of pulling-on piece 3 does not has Time in Ma Gou district 8, just cannot slide fastener normally.

Thus during reality is applied, if the collar of pulling-on piece 3 is inherently positioned at hollow section 7, Thus thief is during stealing (such as not knowing that this designs), with regard to direct pull pulling-on piece 3, it is never Can trigger horse hook 4 and leave slot 10, thus forever cannot open slide fastener, as known perfectly well, this designs, and also needs First the collar of pulling-on piece 3 is moved in Ma Gou district 8, and user is constantly in the middle of the process of movement, Add the theft difficulty of thief.

Gap, described gap >=institute is left between lower end and the upper side of described pull head 1 of described snap fit 5 State the thickness of pulling-on piece 3.

When the collar of pulling-on piece 3 is moved to Ma Gou district 8 from hollow section 7, the collar can only by this gap Can realize, and owing to this gap is sufficiently small, only by the collar alignment gap of pulling-on piece 3, can pass through, Thus thief is during theft, it is to be difficult to just the collar of pulling-on piece 3 is moved to hollow section 7 Ma Gou district 8.
