Description

Technical Field

[0001] The invention relates to a wireless radio frequency identification tag, and in particular to a steel cable type wireless radio frequency identification tag. Background Art

[0002] Existing one-time labels, such as seals for water meters and electricity meters, are mainly used for anti-theft or confidentiality purposes. Such seals can also be applied to locks or tools that need to verify identity, containers or valves of liquid pipelines. Existing seals are to fix an insert at both ends of the wire, or to fix an electronic tag at both ends of the wire. If the seal is to be opened, it can only be opened in a destructive way. Therefore, it can be ensured that the same seal is always fixed there.

[0003] The above-mentioned existing disposable labels, such as lead seals, can achieve the effect of anti-theft, confidentiality or checking the identity information of the setting place. However, since the lead seal itself is usually made of relatively soft materials, when the lead seal is set in an environment where mobile equipment often enters and exits or there are hard objects, the lead seal may be damaged due to accidental collisions with surrounding objects, causing the lead seal to be accidentally damaged due to its inability to withstand collisions. This lead seal device is not suitable for use in certain settings with relatively harsh environments. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a collision-resistant label, which can avoid the problem that when the label is set in a harsh environment, the label is easily damaged by a collision, thereby causing the iron wire or steel wire fixing the label to fall off.

[0005] In order to achieve the above-mentioned object, the present invention provides a steel cable type wireless radio frequency identification tag, comprising a steel cable clip, a protective shell, a wireless radio frequency identification rivet, and a steel cable. The steel cable clip has a clip body, the clip body has a first hardness, and the clip body has a steel cable fixing hole and a steel cable through hole arranged side by side; the direction in which the steel cable fixing hole extends defines an axial direction; the clip body has a receiving chamber, the receiving chamber is communicated with the steel cable through hole, a ratchet gear is arranged in the receiving chamber, and a part of the ratchet gear can extend into the steel cable through hole; the clip body has a first surface and a second surface on opposite sides perpendicular to the axial direction, and a first pin hole runs through the first surface and the second surface. The protective shell has a second hardness greater than the first hardness, and includes a shell body and a cover plate; the shell body is wrapped around the clamp body, the shell body has a first shell body hole on one side corresponding to the second surface, and has a cutout on the other side corresponding to the first surface; the cover plate is arranged at the cutout and has a first cover plate hole, and the first cover plate hole, the first pin hole and the first shell body hole are connected.

[0006] The RFID rivet includes a rivet body and a RFID block. The rivet body has a rod and a head connected to the rod. The rod passes through the first cover plate hole, the first pin hole and the first shell body hole. A rivet head for buckling the shell body is formed at the end of the rod. The head has a countersunk hole. The RFID block is embedded in the countersunk hole and has a RFID chip inside. The steel cable has two ends, one end of which is inserted into the steel cable fixing hole for fixing, and the other end is used to penetrate the steel cable through hole. When the steel cable penetrates the steel cable through hole, part of the steel cable is unidirectionally meshed by the ratchet gear and cannot be pulled out, thereby forming a loop shape on the steel cable.

[0007] The effect of the present invention is that, by setting the hardness of the protective shell higher than that of the steel cable clamp, the steel cable clamp fixing the steel cable is protected by the protective shell, so that the steel cable clamp will not be directly hit. In this way, the problem that the steel cable clamp is damaged by a collision, which may cause the function of fixing the steel cable to fail and cause the steel cable to fall off, can be avoided, so that the steel cable type wireless radio frequency identification tag of the present invention is suitable for use in relatively harsh environments, and the wireless radio frequency identification chip of the wireless radio frequency identification rivet is used to read or write identification or inspection and maintenance data.

[0056] In order to more clearly illustrate the present invention, preferred embodiments are given and described in detail with reference to the accompanying drawings. Figures 1 to 6 As shown, a wire rope type wireless radio frequency identification tag according to a preferred embodiment of the present invention comprises a wire rope clip 10, a protective shell 20, a wireless radio frequency identification rivet 30, and a wire rope 50, wherein:

[0057] The cable clamp 10 has a clamp body 12. Specifically, the clamp body 12 is a flat block of aluminum extrusion and has a first hardness. The means for measuring the first hardness include common hardness testing methods such as Mohs hardness and Rockwell hardness. In other preferred embodiments, the clamp body 12 can also be made of aluminum, copper, magnesium, etc., which are easy to extrude and are more easily deformed by stamping than the protective shell 20.

[0058] The clamp body 12 has a cable fixing hole 121 and a cable through hole 122 arranged side by side; in the preferred embodiment, the cable fixing hole 121 and the cable through hole 122 are through holes and the cable fixing hole 121 is substantially parallel to the cable through hole 122, and the extending direction of the cable fixing hole 121 is defined as an axial direction L. The clamp body 12 has a chamber 123 in the middle, the chamber 123 is communicated with the inner side of the cable through hole 122, the clamp body 12 has a first surface 124 and a second surface 125 on opposite sides perpendicular to the axial direction L, and a first pin hole 126 is passed through between the first surface 124 and the second surface 125, and the axial direction of the first pin hole 126 is defined as a first direction L1. A ratchet gear 16 is provided in the chamber 123, and a portion of the ratchet gear 16 can extend into the cable through hole 122.

[0059] The protective shell 20 includes a shell body 22 and a cover plate 24. Specifically, the shell body 22 and the cover plate 24 are sheet metal parts and have a second hardness respectively. The means for measuring the second hardness include common hardness testing methods such as Mohs hardness and Rockwell hardness. In this preferred embodiment, the shell body 22 and the cover plate 24 are stainless steel sheet metal parts, and the second hardness of the shell body 22 and the cover plate 24 is greater than the first hardness of the clamp body 12. In other preferred embodiments, the protective shell 20 can also be made of other metals with a hardness greater than that of the clamp body 12.

[0060] The shell body 22 is wrapped around the clamp body 12, and the shell body 22 has a first opening 221 and a second opening 222 on opposite sides along the axial direction L, respectively. The clamp body 12 is accommodated in the shell body 22, and the surfaces of the clamp body 12 on opposite sides along the axial direction L are aligned with the peripheries of the first opening 221 and the second opening 222. The shell body 22 has a cutout 223 on one side corresponding to the first surface 124, and the cutout 223 penetrates the shell body 22 on opposite sides along the axial direction L. The shell body 22 has a first shell body hole 224 on the other side corresponding to the second surface 125, and the first shell body hole 224 is connected to the first pin hole 126 of the clamp body 12. The cover plate 24 is a plate having a shape consistent with the cutout 223 and is disposed at the cutout 223. The cover plate 24 has a first cover plate hole 241, and the first cover plate hole 241 is connected to the first pin hole 126.

[0061] The RFID rivet 30 includes a rivet body 32 and a RFID block 34. The rivet body 32 has a rod 321 and a head 323 connected to the rod 321. The head 323 has a countersunk hole 324. The rod 321 passes through the first cover hole 241 of the cover 24, the first pin hole 126 of the clamp body 12, and the first shell body hole 224 of the shell body 22 in sequence. A rivet head 325 is riveted at the end of the rod 321 to buckle the clamp body 12, so that the cover 24, the clamp body 12 and the shell body 22 are firmly buckled. The RFID block 34 is a block with elasticity of rubber or plastic and is embedded in the countersunk hole 324. The RFID block 34 has a RFID chip 341 (RFID) inside, which can be used for near-field reading of data stored in the RFID chip 341 or writing data to the RFID chip 341.

[0062] The steel cable 50 has two ends, and one end is inserted into the steel cable fixing hole 121 of the steel cable clamp 10 for fixing. Specifically, after one end of the steel cable 50 is inserted into the steel cable fixing hole 121, the hole wall of the steel cable fixing hole 121 is pressed around the steel cable fixing hole 121 so that the end of the steel cable 50 inserted into the steel cable fixing hole 121 is clamped and fixed. The other end of the steel cable 50 is inserted into the steel cable through hole 122 of the steel cable clamp 10. In other embodiments, one end of the steel cable 50 can also be combined with the steel cable fixing hole 121 by means of welding, screwing, bonding or snapping.

[0063] When the above preferred embodiment is used, please refer to Figure 1 as well as Figures 7 and 8 As shown, the steel cable 50 is used to hang the steel cable type RFID tag 100 on mechanical equipment, liquid pipelines, etc. The information stored in the RFID chip 341 of the RFID rivet 30 can be read when checking the maintenance status of the equipment, so that the personnel who inspect the equipment can obtain the relevant data of the maintenance history of the equipment. Or after inspecting the equipment, the relevant information of the inspection is written into the RFID chip 341 of the steel cable type RFID tag 100 attached to the equipment, and the required data is retained in the RFID chip 341 for subsequent inspection.

[0064] When the wire rope type RFID tag 100 is set, the other end of the wire rope 50, that is, the free end, is passed around the position where the wire rope type RFID tag 100 is to be hung, and then the free end of the wire rope 50 is inserted into the wire rope through hole 122 of the wire rope clip 10. When the free end of the wire rope 50 is inserted into the wire rope through hole 122 and the wire rope 50 passes the side of the ratchet gear 16, part of the wire rope 50 will be unidirectionally meshed by the ratchet gear 16. At this time, if the free end of the wire rope 50 moves backward, it will be engaged and stuck by the ratchet gear 16, and can only continue to penetrate the wire rope through hole 122 but cannot be pulled out in the opposite direction. Therefore, after the steel cable 50 is formed into a loop shape with both ends constrained by the steel cable clamp 10, the steel cable type wireless radio frequency identification tag 100 is hung and looped on a fixed place such as a mechanical device or a liquid pipeline; at this time, if the steel cable type wireless radio frequency identification tag 100 is to be separated from the setting place, the steel cable clamp 10 must be destroyed to untie the loop of the steel cable 50, so it has the effects of one-time use, confidentiality, anti-theft and proof of data correctness.

[0065] When the environment in which the wire rope type RFID tag 100 is set often has moving objects such as machinery and vehicles or hard objects, the hardness of the protective shell 20 is higher than that of the wire rope clamp 10, so that the wire rope clamp 10 fixing the wire rope 50 can be protected by the protective shell 20. This can avoid the problem that the wire rope clamp 10 is damaged and may cause the function of fixing the wire rope 50 to fail. In addition, when the clamp body 12 is a metal extrusion, sharp burrs are often generated around it. By covering the surrounding of the clamp body 12 with the protective shell 20, human body injuries that may be caused by human hands touching the burrs of the clamp body 12 can also be avoided. The device that rivets the cover plate 24, the clamp body 12, and the shell body 22 with the rivet body 32 can clamp the clamp body 12 along the first direction L1 through the shell body 22 and the cover plate 24 on both sides, so as to obtain the fastening effect of fastening the wire rope clamp 10 to the protective shell 20 and making it difficult to separate.

[0066] Please see Figures 1 to 5 As shown, other parts of the above preferred embodiment are further described. The chamber 123 of the clamp body 12 is a space that penetrates along the axial direction L. A core plate 14 is provided to cooperate with the chamber 123. The core plate 14 is inserted into the chamber 123 of the clamp body 12 and is fixed by the hole wall of the chamber 123. The core plate 14 has an inclined groove 141 on one side adjacent to the steel cable through hole 122, and the inclined groove 141 is communicated with the steel cable through hole 122. The ratchet gear 16 is located in the inclined groove 141, and a spring 161 is arranged between the ratchet gear 16 and the inner end of the inclined groove 141. The spring 161 supports the ratchet gear 16 in a direction inclined to the axial direction L, so that the ratchet gear 16 extends part of it into the steel cable through hole 122. The core plate 14 has a first core plate hole 142 at a position corresponding to the first latch hole 126, and the first core plate hole 142 is communicated with the first latch hole 126.

[0067] The rivet body 32 has an embossing 322 around the rod portion 321. When the rod portion 321 of the rivet body 32 passes through the first core plate hole 142, the first pin hole 126, the first cover plate hole 241 and the first shell body hole 224, the embossing 322 can be pressed against the hole walls of the first core plate hole 142, the first pin hole 126, the first cover plate hole 241 and the first shell body hole 224, so that the rivet body 32 is more tightly riveted to the first core plate hole 142, the first pin hole 126, the first cover plate hole 241 and the first shell body hole 224.

[0068] A second pin hole 127 is further passed through between the first surface 124 and the second surface 125 of the clamp body 12 along the first direction L1, and the core plate 14 has a second core plate hole 143 at a position corresponding to the second pin hole 127. The shell body 22 has a second shell body hole 225 on a side corresponding to the second surface 125, and the second shell body hole 225 is connected to the second pin hole 127 of the clamp body 12. The cover plate 24 has a second cover plate hole 242, and the second cover plate hole 242 is connected to the second pin hole 127. A second rivet 40 is riveted to the second core plate hole 143, the second pin hole 127, the second cover plate hole 242, and the second shell body hole 225. The protective shell 20 is more tightly riveted to the periphery of the cable clamp 10 by the second rivet 40.
