Abstract

A clamp-type article surveillance device applied to the electronic article surveillance industry comprises: a rotatable first clamping arm (2) and a second clamping mating component (3). The first clamping arm (2) and the second clamping mating component (3) work together to clamp an article. The surveillance device is provided with an eccentric wheel (4) for driving the first clamping arm (2) to rotate so as to clamp-fit the second clamping mating component (3) or to release the clamp-fit. The surveillance device is further provided with a handle (5) for operating the eccentric wheel to rotate. The surveillance device is further provided with a lock for locking the handle at a current position when the surveillance device is in a clamping state. The lock is a magnetic lock. The structure and operation of the present invention are both very simple, and the present invention can be fixed on a surface of a leather article, for example any portion on a shoe upper, a boot tube, and leather clothes through clamping without damaging leather articles.

Description

Clip type commodity anti-theft device applied in electronic article anti-theft industry

The invention relates to a clip-type article anti-theft device applied to the electronic article anti-theft industry. Background technique

For some goods stored on open shelves in a business place such as a supermarket, in order to prevent theft, the merchants are increasingly using anti-theft devices to connect the anti-theft devices on the products. For cloth products, nail-type anti-theft devices are often used for anti-theft, but such anti-theft devices can only be applied to cloth products at most, even for cloth products, a slight carelessness will leave unsightly needle holes on the goods. Even broken. The same problem also exists in the anti-theft of other leather goods. Summary of the invention

The technical problem to be solved by the present invention is to provide a clip-type article anti-theft device for use in the electronic article anti-theft industry, which can be conveniently fixed on leather goods so that the anti-theft tag carried by the anti-theft tag acts as a theft prevention function. To this end, the present invention adopts the following technical solution: It comprises a rotatable first clamping arm, a second clamping and mating component, the first clamping arm and the second clamping engagement component cooperate to clamp the commodity; the anti-theft device is provided with an eccentricity The wheel drives the first clamp arm to rotate to engage or disengage the second clamp mating component.

Based on the above technical solutions, the present invention may also adopt the following further technical solutions:

It is provided with a handle for operating the rotation of the eccentric; it is also provided with a lock which locks the handle in the current position when in the clamped state, the lock being a magnetic lock.

It is provided with a housing, the first clamping arm projects from the housing, the eccentric is disposed within the housing, and the handle is disposed outside the housing.

At least one of the first and second clamping engagement members is an elastic clamping member. The first clamping arm is a resilient arm.

The second clamping mating component is part of the surface of the housing or a component that is fixed to the surface of the housing.

It is provided with a first clamp arm return assist spring opposite to the action of the eccentric.

The handle corresponds to a position in the clamping state of the anti-theft device in a position to be turned back to the side of the housing, the lock having a locking tongue for the handle that can be pressed from the other side of the housing, The lock is provided with a bolt backstop member that can be displaced by the magnet, and the inside of the handle is provided with a lock hole that cooperates with the bolt.

The surface of the housing is provided with a limit card slot when the handle is turned back to the side of the housing and the position of the handle when the anti-theft device is in the clamped state is reached.

The lock is provided with a return spring of the lock tongue and a front top spring of the lock tongue retreating blocking member.

Since the technical solution of the present invention is adopted, the structure and operation of the present invention are very simple, and the present invention can be fixed to the surface of a leather-like article by gripping, such as any part of the upper, the boot, and the leather garment, without damaging the product. Further, the present invention can be widely applied to a variety of products capable of providing a gripped portion to function as an antitheft device. DRAWINGS

Refer to the attached drawings. The invention comprises a housing 1, a rotatable first clamping arm 2 extending from the housing, a first clamping arm 2 and The second clamping and fitting member 3 cooperates with the clamping product; the housing 1 is provided with an eccentric wheel 4 for driving the first clamping arm 2 to rotate to be clamped or disengaged from the second clamping and mating component 3, A handle 5 for operating the rotation of the eccentric wheel 4 is disposed outside the housing; the anti-theft device is provided with a lock that locks the handle in the current position when in the clamped state, and the lock is a magnetic lock, that is, the lock tongue is attracted by the magnet Or a lock that can be unlocked by blocking the moving parts of the tongue. The gripping state is the state in which the product is held.

At least one of the first clamping arm 2 and the second clamping engagement component 3 is an elastic clamping component, so that the invention can automatically adapt to the clamped object 100 of different thicknesses, thereby ensuring reliable clamping without Damage damage is caught in the object. The embodiment of the present invention may be: the first clamp arm 2 is a resilient arm composed of a resilient elastic piece or an elastic body similar to a rubber-like material is disposed on the first clamp arm 2. The second clamping and fitting member 3 is a part of the surface of the casing or a member fixed to the surface of the casing, and the surface of the second clamping and fitting member 3 may also be provided with an elastic pad.

The present invention is also provided with a first clamp arm return assist spring 6 which is opposite to the eccentric 4 .

As shown in FIG. 2, 3, 5, 6, 7, and 8, the position of the handle 5 corresponding to the anti-theft device in the clamping state is in the position of being turned back to the side of the housing (ie, the handle is in FIG. 2 The position in the 3), the lock has a locking tongue 7 for the handle that can be pressed from the other side of the housing, the lock being provided with a locking tongue backing blocking member that can be displaced by the magnet 8.
