Description

A reusable anti-demolition RFID device

technical field

The utility model relates to an RFID device.

Background technique

For some commodities stored on the open shelves of supermarkets and other business places, in order to prevent theft and data management, merchants are increasingly using RFID tags, and the method of connecting RFID tags to commodities is used for anti-theft + data management. As far as the connection between the anti-theft device and the product is concerned, there are bundle type, clip type, nail type, card type, etc. However, most of the structures are relatively complicated, and it is difficult to apply it to precious and small items such as jewelry and watches. For clothing products, many nails are used to fix them on the product. In this way, the nails will pierce the clothing, which is not liked by customers. .

Contents of the invention

The technical problem to be solved by the utility model is to provide a reusable anti-demolition RFID device with a simple structure, which can be used for storing and reading jewelry, watches, and clothing commodity information. For this reason, the utility model adopts the following technical solutions:

A reusable anti-demolition RFID device that can be used for storing and reading information on jewelry, watches, and clothing products, including an RFID tag INLAY and its plastic casing, is characterized in that the RFID device is provided with a sling, a sling The two ends of the two are free ends, and the free end has a plastic clip. The inside of the plastic body is provided with a channel for the part of the clip to slide from the main body of the plastic case. The top of the plastic case is provided with an insertion port for the plastic clip. The head snaps irreversibly into the plastic housing after insertion into the top of the housing.

Further, the chuck includes a connecting column connected to the sling and a tapered plug, a clamping neck is formed between the connecting column and the tapered plug, and there is an inverted acute angle clip matching with the chuck in the housing. Two ribs at the corner, the inverted acute angle between the two ribs forms the introduction port of the tapered plug, the inner narrow opening of the two ribs is stuck at the clamping neck, Form an irreversible snap joint.

The channel consists of two ribs.

The plastic housing has a discharge port for the ejected part of the chuck at the end of the channel.

The shell is a flat shell in the shape of a sign.

Due to the adoption of the technical solution of the utility model, the utility model fully considers the erasable and writable reusability of the RFID tag, and proposes an irreversible clamping connection structure combined with a fall-off elimination solution, which makes the connection structure simple and low in cost. It is also easy to connect and operate, and can prevent easy disassembly and can also realize the reusability of the main part of the device; furthermore, the utility model makes full use of the material toughness of the parts and the correlation between the movement characteristics, and rationally arranges the direction and direction of the parts. position, the tag can be made small and reliable, combined with RFID electronic tags to form an information storage device that can be applied to jewelry, watches, clothing and other industries.

Detailed ways

Refer to attached picture. The reusable anti-disassembly RFID device provided by the utility model includes an RFID tag INLAY1 and its plastic casing 2, and the RFID tag INLAY is an assembly composed of an antenna and an RFID chip in the RFID tag, and the RFID tag is set There is a suspension rope 3, the two ends of the suspension rope 3 are free ends, and the free ends have plastic clips 31, 32. When the suspension rope is pulled under a certain strength, the clips 31, 32 at both ends of the suspension rope will not fall off. The inside of the plastic body is provided with a channel for the part of the clip to slide down from the main body of the plastic case. The top of the plastic case is provided with an insertion port for the plastic clip. middle.

When the RFID device is connected to the commodity to be connected, the sling 3 passes through the commodity (such as through the chain hole of a necklace, the ring of a ring, the buttonhole of a garment, etc.), and the plastic clip 31 at one end first It is inserted into an insertion port on the top 20 of the housing, and is irreversibly clamped in the plastic housing. After the other end passes through the product, its plastic clip is inserted into the top 20 of the housing and is irreversibly clamped in the housing.

This kind of irreversible clamping is not like the conventional plastic clamping that can be clamped, pulled out, and clamped frequently. The irreversible clamping of the utility model makes it impossible to open the shell 2 or destroy the shell 2, the plastic card Otherwise, the plastic clips can no longer be pulled out of the housing 2 to release the above clamping connection. When it needs to be reused, cut the middle of the lifting rope 3, and the plastic clips 31 and 32 at both ends pass through the plastic casing through the channels 23 on both sides. The outlet 26 at the end of the passage on the main body slides out, and the reusability of the main body is realized by replacing the sling 3. The housing top 20 corresponding to the chucks 32, 31 can be the top of the same side of the housing, or is the top of the opposite side of the shell.

The chuck 31 includes a connecting column 311 connected to the sling and a conical plug 312. Since the conical plug 312 is larger in size than the connecting column 311 to form a neck structure, the housing 2 has a forming part that matches the chuck 31. The two ribs 21, 22 of the inverted acute angle, the inverted acute angle between the two ribs 21, 22 forms the inlet 41 of the tapered plug, when the chuck 32 is inserted into the inlet At 31 o'clock, the two ribs 21, 22 are slightly deformed, and the tapered head can pass through the inner narrow opening 42 of the two ribs, and the inner narrow opening 42 of the two ribs is stuck at the clamping neck, forming Irreversible snap-in.

The structure of the utility model is extremely simple, and the shell can be made into a flat shell in the shape of a sign, such as a rectangular flat shell, a circular flat shell, or a flat shell of other shapes. The utility model is small in size and simple in structure, and can be used Store and read product information of jewelry, watches, and clothing.
