Magnetic pushing force anti-theft label
Technical field
The present invention relates to a kind of magnetic pushing force anti-theft label, be widely used in the antitheft of shop or supermarket commodity.
Background technology
Anti-theft tag is a kind of anti-theft product that is widely used on the commodity market, mainly comprise the locking type anti-theft tag, adopt specific physical construction to make latch mechanism, lock antitheft nail, it is fixed on the commodity, can only just can opens by separating lock tool accordingly; The alarming type anti-stealing label by electronics or other alarm elements are set, sends alerting signal in label; The composite type anti-theft tag has the characteristics of above-mentioned two kinds of anti-theft tags concurrently.
Through being extensive use of, traditional magnetic anti-theft label has lacked absolute safe antitheft function, is opened by any magnetite easily.Applicant of the present invention discloses a kind of anti-theft tag of safe ready in its practical novel patent No. ZL200620045680.X, on the basis of traditional latch mechanism, further set up horizontal positioner, make that anti-theft tag must be under vertical and horizontal two-way function power condition, promptly be equiped with the effect of setting up horizontal magnetic force on the nail nipping device of magnetic patch in original bottom, after opening the clamping mechanism on the latch mechanism earlier, just can utilize the magnetic patch of nail nipping device bottom to open latch mechanism, anti-theft tag is opened, greatly strengthened security.
But the version slightly complicated of this dual release from the both direction, and anyone can carry several pieces of magnetic patch and open horizontal clamping mechanism with a magnetic patch earlier, use a unlatching latch mechanism again, still be not perfectly safe so all adopt magnetic action to open antitheft nail latch mechanism.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of magnetic pushing force anti-theft label of new structure, adopt different magnetic thrusts in the past, but not magnetic attraction is finished opening latch mechanism in conjunction with the magnetic switch device on the latch mechanism.
The present invention solves the problems of the technologies described above the technical scheme of taking: a kind of magnetic pushing force anti-theft label, comprise the shell that constitutes by loam cake and base, be provided with the coil alarm between loam cake and the base, antitheft nail latch mechanism, antitheft nail inserts in the shell and by latch mechanism from loam cake and locatees, wherein, latch mechanism comprises: the cross section is trapezoidal locking pearl cap, locking pearl holder with locking pearl cap inner chamber coupling, be no less than three locking pearl and replace the spring assembly of locking the pearl holder, latch mechanism is corresponding with the magnetic force lockaid gun and opened by it, described latch mechanism is provided with the magnetic switch device, magnetic patch in the magnetic switch device is promoted to move to the direction away from magnet by the magnet in the lockaid gun, and magnetic patch promotes latch mechanism and opens.
Design concept of the present invention is: utilize interior magnetic patch of magnetic switch device and the interaction force between the magnet in the corresponding lockaid gun, promote moving of magnetic patch.Under locking state, spring device is replaced locking pearl holder, because locking pearl holder and cross section are trapezoidal locking pearl cap inner chamber coupling, locking pearl cap radial compaction is located at the locking pearl in the locking pearl holder through hole, thereby the antitheft nail that will pass locking pearl holder is locked.When magnetic patch promoted latch mechanism, locking pearl holder was urged downwardly, and broke away from locking pearl cap, and the locking pearl no longer is subjected to locking the radial pressure of pearl cap thereby discharges locking nail.After lockaid gun left anti-theft tag, under the replacing of spring device, locking pearl holder reentered in the locking pearl cap, and locking nail is retightened.
On the basis of such scheme, a kind of magnetic switch device that promotes to lock the pearl holder is provided, described magnetic switch dress is locked the pearl holder and is provided with pressing down section by being located at least one magnetic patch in the shell and being made up of the slide block that magnetic patch promotes, and slide block is located on the pressing down section.
On the basis of such scheme, a kind of concrete anti-theft tag structure is provided, described slide block constitutes by horizontal circular type arm with from the straight-arm that circular type arm stretches out downwards, and circular type arm is set on the holder pressing down section, which is provided with a pair of fulcrum by the shell positioning of rotating; Magnetic patch is located at the limiting section below of straight-arm inboard, and the lower end of magnetic patch is located at the screens portion place of base; Magnetic patch is subjected to thrust along sliding on the straight-arm inboard, and the disengaging screens portion and the pushing and pressing slide block that outwards traverses rotate around fulcrum and press down holder, and latch mechanism is opened.
On the basis of such scheme, another kind of concrete anti-theft tag inner structure is provided, described slide block constitutes by horizontal circular type arm with from the straight-arm that circular type arm stretches out downwards, circular type arm is set on the holder pressing down section, which is provided with the fulcrum by the shell positioning of rotating, straight-arm is located at the top of magnetic patch; Magnetic patch is subjected to thrust along sliding on the base, promotes slide block and presses down holder around the fulcrum rotation, and latch mechanism is opened.
On the basis of such scheme, the third concrete anti-theft tag inner structure is provided, described slide block is horizontal ring-like, and ring-like is set on the holder pressing down section, which is provided with the protuberance by shell chute location, and the bottom is provided with the inclined-plane; The top of magnetic patch is provided with a pushing block, and pushing block is replaced annular element; Magnetic patch is along pushing block on the base intracavity, and pushing block pushing and pressing slide block laterally slides, and its inclined-plane presses down holder, and latch mechanism is opened.
On the basis of such scheme, the 4th kind of concrete anti-theft tag inner structure is provided, described slide block is made of screw-casing and a pair of pivot arm, screw-casing is enclosed within the holder outside, the bottom is provided with notched inclined-plane, and breach is located on the holder pressing down section, and a pair of pivot arm supports the location by shell, one pivot arm is located at the spring place, and another pivot arm is located at the magnetic patch place; Magnetic patch is along sliding on the base intracavity, and the top can be designed to the inclined-plane, and the magnetic patch inclined-plane upwards promotes the pivot arm rotation, and the inclined-plane of screw-casing presses down holder, and latch mechanism is opened; Otherwise spring promotes the pivot arm reverse rotation, and screw-casing resets, latch mechanism locking.
The inclined-plane of described rotary sleeve is provided with at least one.
Magnetic force direction is in the past opened latch mechanism thereby the present invention aims to provide a kind of difference, and the structure of concrete pushing locking pearl holder can also have other numerous forms.
On the basis of such scheme, the oblique in the enclosure setting of described magnetic patch is also promoted obliquely by magnet.
On the basis of such scheme, the pressing down section of described locking pearl holder is projection or bulge loop.Projection generally is provided with a pair of of symmetry, to guarantee downward equalization of pressure.
At the magnet ring type lockaid gun of above-mentioned anti-theft tag, described lockaid gun is the magnetic patch of band endoporus, or the stacked magnetic patch that forms of magnetic patch of at least two band endoporus of serving as reasons.
The invention has the beneficial effects as follows:
The invention provides a kind of novel release form, non-traditional magnetic attraction is opened latch mechanism by magnetic thrust, for anti-theft tag commonly used provides a kind of simple safe and reliable again new model.
