Description

Technical Field

[0001] The invention relates to a commodity anti-theft device, in particular to a single-rope loose-rope alarm binding label, which is suitable for the anti-theft of small boxed products or blister products in retail malls. Background Art

[0002] The applicant's prior application 202420749800.2 discloses a commodity anti-theft device, including a first half shell, a PCB assembly, a wire rope assembly, a second half shell and a lock core assembly. The PCB assembly is arranged in a shell composed of the first half shell and the second half shell. The wire rope assembly includes a copper buckle, two leads and a steel wire rope. The fixed end of the steel wire rope is arranged in the shell. The fixed end is provided with a copper buckle and two leads. The two leads are electrically connected to the PCB assembly to form an electronic circuit. The free end of the steel wire rope passes through the lock core assembly. The part of the steel wire rope outside the shell forms a circular ring and is tied to the protected commodity. When the steel wire rope is cut, the circuit is disconnected and the PCB assembly alarm is triggered. The lock core assembly is provided with a rope loosening dial button. Turning the rope loosening dial button can pull the steel wire rope backward to loosen the rope.

[0003] Since the length of the steel wire rope body exposed outside the shell in the steel wire rope assembly in the above-mentioned patent application is constant, the following problems will occur when using this type of commodity anti-theft device: when the steel wire rope in the steel wire rope assembly is too long relative to the bundled commodity (that is, the volume of the protected commodity is small, and in addition to the required length of the steel wire rope body bundled on the commodity, there is a remaining length of the steel wire rope body exposed outside the shell), the excess steel wire rope body needs to be bound and fixed by a buckle to solve the problem of the steel wire rope being too long (if the excess steel wire rope body is not bound and fixed, it will occupy a large amount of retail space on the commodity shelves). However, binding and fixing the steel wire rope body by the buckle will form a larger "knot", and the formation of the "knot" not only makes the bundling process of the commodity anti-theft device more cumbersome, but also makes the overall appearance unsightly. At the same time, the formation of the "knot" will still occupy a small amount of retail space on the commodity shelves. Summary of the invention

[0004] Design purpose: In order to avoid the shortcomings of the background technology, a single-rope loose rope alarm bundling tag is designed that can not only provide bundling protection for goods of different sizes, but also improve the utilization rate of the retail space of the goods shelves, while also improving the assembly efficiency of the protected goods. The structure is more compact and the protection safety is good.

[0005] Design plan: To achieve the above design objectives.

[0006] 1. A winding shaft is provided in the housing and the winding shaft is rotatably installed between the surface housing and the bottom housing. A ratchet shaft is provided on the winding shaft and a ratchet 1 is provided on the outer circumferential surface of the ratchet shaft. A rotating hole is provided in the middle of the tooth block and the rotating hole passes through the front and back sides of the tooth block. The tooth block is movably installed in the housing by plugging and cooperating with the tooth block rotating column in the housing through the rotating hole. A ratchet 2 is provided on the upper part of the tooth block and a protrusion is provided on the lower part of the tooth block. The ratchet on the tooth block can be moved by pushing the protrusion. The second part is engaged or disengaged with the ratchet tooth one of the winding shaft; a locking piece limiting guide groove is provided in the shell, and a locking piece is provided in the locking piece limiting guide groove; the locking piece is provided with a locking hole and a locking through hole which pass through the upper and lower end surfaces of the locking piece, and the locking hole and the locking through hole are communicated; a push button limiting hole is provided on the shell on the side where the wire rope through hole two is located, and a push button is clamped in the push button limiting hole, and the push button can move back and forth along the length direction of the push button limiting hole, and the fixed block in the push button is fixedly connected to the locking piece through a connecting piece , by moving the push button, the locking hole on the lock plate can be aligned with the second wire rope through hole, or the lock through hole on the lock plate can be aligned with the second wire rope through hole; one end of the wire rope in the wire rope assembly is fixedly connected to the winding shaft after passing through the first wire rope through hole, and the wire rope can be wound on the shaft body of the winding shaft when the winding shaft is rotated, the other end of the wire rope is provided with a plug and a card slot is provided on the outer circumferential surface of the plug, the diameter of the plug matches the diameter of the lock through hole and the diameter of the plug is greater than the width of the locking hole, when the plug passes through the second wire rope through hole and the lock through hole in turn and the front end of the plug presses the locking switch in the PCB assembly to close and is in conductive contact with the thrust spring in the PCB assembly, the push button is moved to make the locking hole and the card slot match; a conductive sheet is provided in the shell, one end of the conductive sheet is conductively connected to the PCB assembly and the other end of the conductive sheet is in conductive contact with the end of the wire rope arranged on the winding shaft, which is one of the technical features of the present invention. The purpose of such a design is: since a single-rope loose rope alarm bundling tag can reel in excess wire rope into a shell, such a single-rope loose rope alarm bundling tag can not only provide bundling protection for commodities of different sizes, but also the commodities bundled and protected by such a tag do not occupy the retail space of commodity shelves (since there is no excess exposed wire rope), thereby improving the utilization rate of the retail space of commodity shelves. At the same time, due to the high efficiency of winding excess wire rope, the assembly efficiency of the single-rope loose rope alarm bundling tag and the protected commodities is improved.

[0007] 2. A locking hole and a lock through hole are provided at one end of the upper end surface of the locking plate, the locking hole being a strip-shaped through hole and the length of the strip through hole being greater than the width, and the other end of the upper end surface of the locking plate being a tooth block limiting hole which is through the upper and lower end surfaces of the locking plate, the protrusion being inserted into the tooth block limiting hole, the tooth block limiting hole being a strip hole, the diameter of the protrusion matching the width of the strip hole and the diameter of the protrusion being smaller than the length of the strip hole; the locking hole is located outside the lock through hole and the lock through hole is closer to the tooth block limiting hole than the locking hole; when the lock through hole and the wire rope through hole are aligned with each other, the ratchet tooth 2 on the tooth block and the ratchet tooth 1 on the winding shaft are in a disengaged state. At this time, the plug can be inserted into the wire rope through hole 2 or the plug can be pulled out from the wire rope through hole 2, the winding shaft can rotate in both directions, and the wire rope can be wound around the winding shaft when the winding shaft rotates forward. When the locking hole is directly opposite to the second wire rope through hole, the second ratchet on the tooth block is engaged with the first ratchet on the winding shaft to stop retreat. At this time, the plug cannot be inserted into the second wire rope through hole or the plug cannot be pulled out from the second wire rope through hole. The winding shaft can only rotate in one direction and the rotating winding shaft can wind the wire rope around the winding shaft body. When the locking through hole is directly opposite to the second wire rope through hole, the second ratchet on the tooth block is engaged with the first ratchet on the winding shaft to stop retreat. At this time, the plug cannot be inserted into the second wire rope through hole or the plug cannot be pulled out from the second wire rope through hole. The design that the winding shaft cannot rotate is the second technical feature of the present invention. The purpose of this design is: since a single-rope loose rope alarm bundling tag can realize the insertion and removal of the free end of the wire rope, as well as the tightening of the wire rope, with a push button, such an ingenious structure not only optimizes the overall structure of a single-rope loose rope alarm bundling tag, reduces the overall volume of a single-rope loose rope alarm bundling tag (the structure is more compact), but also further improves the ease of use of a single-rope loose rope alarm bundling tag.

[0008] 3. A mounting plate is provided on the upper end surface of the locking plate, and a push button limiting hole is provided on the mounting plate, which passes through the front and back sides of the mounting plate. A threaded hole is provided on the fixing block in the push button. After the threaded hole and the push button limiting hole are connected, the fixing block and the mounting plate are fixedly connected by screw three. A spring limiting cavity is provided in the shell, and a spring one is provided in the spring limiting cavity. One end of the spring one contacts the inner wall surface of the spring one limiting cavity, and the other end of the spring one contacts the side surface of the push button. When the lock through hole and the wire rope through hole two are directly opposite, the locking plate drives the push button to approach the spring one limiting cavity. At this time, the design that the spring one is compressed is the third technical feature of the present invention. The purpose of such design is: pushing the push button makes the lock through hole and the second wire rope through hole face each other, and then inserting the plug into the second wire rope through hole. After the plug passes through the second wire rope through hole and the lock through hole in turn, it is pressed and closed with the locking switch in the PCB assembly, and at the same time, it is conductively contacted with the thrust spring in the PCB assembly. After that, the user releases the push button. Since the spring one is in a compressed state, the lock plate automatically moves along the lock plate limit guide groove under the action of the restoring force of the spring one until the locking hole and the slot on the plug are engaged. That is, after the plug is inserted into place through the second wire rope through hole, it can be automatically engaged under the action of the spring one.

[0009] 4. The conductive sheet includes a fixed end, an elastic end and a pin. The conductive sheet is electrically connected to the circuit board in the PCB assembly by welding through the pin. The elastic end is suspended in the wire-receiving cavity in the housing. A copper buckle is provided on the end of the steel wire rope arranged on the winding shaft. A contact head is provided on the elastic end and the contact head is in conductive contact with the copper buckle. At this time, the steel wire rope forms an electrical circuit, which is the fourth technical feature of the present invention. The purpose of this design is that due to the reasonable structural design and ingenious structure of the conductive sheet, it not only improves the space utilization rate of a single-rope loose rope alarm bundle tag (which is conducive to the miniaturization of a single-rope loose rope alarm bundle tag), but also reduces the production cost of a single-rope loose rope alarm bundle tag.

[0010] 5. The conductive sheet includes a fixed end, an elastic end, and a pin. The elastic end is composed of a needle tube, a needle head, and a spring. The needle tube is welded and fixed on the fixed end. The needle head can be telescopically moved axially in the needle tube after being fitted with the spring. Moreover, the needle head is in conductive contact with the copper buckle. At this time, the steel wire rope forms an electrical circuit, which is the fifth technical feature of the present invention. The purpose of this design is that: due to the reasonable structural design and ingenious structure of the conductive sheet, it not only improves the space utilization rate of a single-rope loose rope alarm bundling tag (which is conducive to the miniaturization of a single-rope loose rope alarm bundling tag); in addition, since the elastic end is composed of a needle tube, a needle head, and a spring, the elastic end of this structure can be more accurately and reliably in conductive contact with the copper buckle.

[0011] 6. A rope loosening button is provided in the shell, and the rope loosening button is provided with a wire rope through hole, a positioning hole, a pressure plate and a hinge shaft. The hinge shaft is clamped between the rope loosening button hinge hole of the bottom shell and the hinge hole of the surface shell. The second set of springs is installed between the rope loosening button spring limit column and the positioning hole of the bottom shell, and the rope loosening button can rotate up and down; the pressure plate is opposite to the button of the rope loosening switch, and the wire rope passes through the wire rope through holes. When the wire rope is tightened, the wire rope pulls the rope loosening button downward through the wire rope through hole of the rope loosening button. At the same time, the pressure plate presses down the rope loosening switch to realize the closing of the rope loosening switch. At this time, a design in which a single-rope loosening alarm bundling tag is in a rope loosening alert state is the sixth technical feature of the present invention. The purpose of such design is that when the wire rope is cut or loosened, the wire rope no longer presses the rope loosening button, and the rope loosening button moves upward under the action of the restoring force of the spring. At this time, the block loosens the rope loosening switch and triggers the alarm, which greatly improves the safety of the goods protected by a single-rope loosening alarm bundling tag. In addition, the rope loosening button of this structure realizes the power-on of the rope loosening switch through the tightening force of the wire rope. Such a single-rope loosening alarm bundling tag can provide anti-theft protection for goods of different sizes with the same effect, that is, a single-rope loosening alarm bundling tag has a good protection effect.

[0012] 7. The bottom shell is provided with a battery cavity, the bottom shell is provided with a fixing column and the outer end surface of the fixing column is provided with a threaded hole, the bottom shell is provided with a battery cover notch, a convex block is provided on one side of the battery cover and a lug is provided on the other side of the battery cover, the lug is provided with a fixing hole that passes through both sides of the lug, the convex block matches the notch of the bottom shell battery cover, and the battery cover is fixedly connected to the bottom shell by screws 4 after the fixing hole and the threaded hole on the fixing column are connected, which is the seventh technical feature of the present invention. The purpose of this design is to quickly remove the battery cover and replace the battery, thereby extending the service life of the product.

[0013] 8. A winding shaft hinge hole is provided at one end of the winding shaft that is assembled with the face shell, and a hinge hole matching the winding shaft hinge hole is provided on the independent handle. The design that the independent handle is hinged to the winding shaft through the hinge shaft after the winding shaft hinge hole is connected to the hinge hole is the eighth technical feature of the present invention. The purpose of such a design is that since the independent handle can be hinged to the winding shaft through the hinge shaft after the winding shaft hinge hole is connected to the hinge hole, and the independent handle is also provided with a notch 1 matching the shape of the winding shaft, a notch 2 for operation, and a convex rib matching the face shell, when it is necessary to open the independent handle, insert a finger into the notch 2, and apply force upward to open the independent handle for rotating the winding shaft. When the independent handle is not needed, fold the independent handle and hide it in the handle cavity, which saves space better and further realizes the miniaturization of a single-rope loose rope alarm bundling tag; in addition, when the independent handle is not needed, the independent handle hidden in the handle cavity 1-1 can also play a role in limiting the rotation of the winding shaft.
