The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of latching device of anti-theft box is provided, to be used for the packing of treasure.

The utility model anti-theft box latching device comprises: baffle plate 5, baffle plate 5 bottom surfaces are provided with locking hole a and T shape slide block g, and the side of baffle plate 5 has pin-and-hole b; Be arranged at the mounting hole 4 and the T shape chute f of box body 1 bight one side, and the pin c of box body another side; And be installed on lock 6 and spring 7 in the mounting hole 4 of described box body.T shape slide block g on the baffle plate 5 slides in the T slot f of box body 1, inwardly promotes baffle plate 5, and the boss of lock 6 inserts among the locking hole a of baffle plate 5 bottom surfaces under spring 7 effects, and the pin c on the box body snaps among the pin-and-hole b of plate washer 5 sides simultaneously.

The latching device of this anti-theft box, simple in structure, easy to use, reliable, the oad to protected object requires lower simultaneously.Be placed on the commodity in the anti-theft box, can only just can open with purpose made magnetic force lockaid gun, can from antitheft basin, take out protected commodity by the cashier.If want to cause warning by antitheft detecting gate without the cashier, thereby can prevent the stolen of commodity effectively being placed on commodity band in the anti-theft box from the market.

Below in conjunction with accompanying drawing this utility model is described in detail.

Fig. 1 is this anti-theft box locking device structure scheme drawing;

Section-drawing when Fig. 2 is the unlatching of this anti-theft box latching device;

Fig. 3 is Fig. 1 lateral plan;

Fig. 4 is used to deposit the anti-theft box constructional drawing of DVD an official document or note sheet etc. for this latching device.

Shown in Fig. 1-4.Originally the anti-theft box latching device that is used for the DVD video disc has T shape chute f and pin c by cartridge (box body) 1, the baffle plate 5 that is arranged at one jiao of cartridge, lock 6, spring 7 on the cartridge, can adorn the mounting hole 4 of lock 6 and spring 7 and can adorn the oblong aperture 3 of anti-theft tag.T shape slide block g, locking hole a and pin-and-hole b are arranged on the baffle plate 5.

Cartridge and baffle plate are made with the transparent synthetic resin with good strength, can allow client see the synopsis of depositing video disc clearly.

The latching device of anti-theft box in opening as shown in Figure 2, when its baffle plate 5 when push open in the box body outside, DVD video disc 2 grades just can be inserted in the cartridge 1 easily, inwardly promote baffle plate 5, the T shape slide block g on the baffle plate slides among the T slot f in cartridge 1.When shifting the end onto, baffle plate 5 hears " noise made in coughing or vomiting " one, lock 6 is under the effect of spring 7, boss on the lock 6 inserts among the locking a on baffle plate 5 bases, pin c on the cartridge 1 snaps among the pin-and-hole b of plate washer 5 sides simultaneously, as shown in Figure 1, this moment, baffle plate 5 became one with cartridge 1, had promptly formed the packing box with anti-theft feature.

As shown in the figure, the boss 4 of anti-theft box bottom is placed on the centre of lockaid gun, under the effect of lockaid gun magnetic attracting force, lock 6 down move, and the boss on the lock 6 leaves the locking hole a on the baffle plate 5, and this moment, baffle plate 5 just can promotion back and forth in blocking basin.When baffle plate outwards spurred, the pin c on the cartridge was also gradually away from the pin-and-hole b of baffle plate side, and baffle plate draws when motionless, and the e face of baffle plate is mutually neat with chuck d face, at this moment just can put, get DVD an official document or note sheet very easily.

Because baffle plate 5 is subjected to T slot f, the lock 6 on the cartridge 1, the restriction of three directions of pin c, so its reliable lock height.Lock is subjected to the effect of spring force, can unblank very easily with the magnetic lockaid gun, and is extremely easy to use.

In sum, when the latching device of anti-theft box under Fig. 2 state, can pack or take out DVD an official document or note sheet easily into.After putting into an official document or note sheet, when the baffle plate on the cartridge is shifted onto end one-tenth Fig. 1 state, promptly constituted integral body as shown in Figure 4 with anti-theft feature.In the time of can only becoming Fig. 2 state with purpose made lockaid gun skimming baffle with cartridge by the cashier, could take out the DVD an official document or note sheet in the box.This mode of pinning cartridge and block with pinning, spring, pin, structure is simpler, use is more convenient, reliability is higher.
