Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic tags, in particular to a metal metering box electronic tag. BACKGROUND

[0002] The metal metering box is a kind of electric metering device, which is fully enclosed and managed, and is mainly used for preventing electricity theft. The design and manufacture of the metal metering box consider various environmental adaptability and flexibility of installation methods. They adopt a universal structure design, including a hanging type, an embedded type, a pole type and the like, and through the configuration of corresponding accessories, the installation of different environments and installation methods can be realized.

[0003] With the popularization of intelligent management, the metal metering box is provided with an electronic tag, i.e. an RFID tag, which becomes a key technical means for rapid inspection identification and state information association. Due to the complex electromagnetic environment formed by the metal box itself, and the fact that it is often deployed outdoors or in harsh working conditions, the tag needs to withstand multiple environmental stress challenges such as temperature and humidity changes, chemical corrosion, electromagnetic interference and physical vibration for a long time, which puts high requirements on the selection, installation and protection of the tag.

[0004] In order to adapt to the particularity of the metal surface and the complex environment, the existing electronic tags are usually installed on the inner and outer surfaces of the metering box by means of adhesive bonding, riveting, screw fixing or buckle embedding. Although these methods solve the problems of tag adhesion on the metal surface and signal optimization to some extent, they have significant deficiencies in physical theft prevention and anti-violence destruction. Commonly used adhesive tags are easy to be torn off or scraped off as a whole, and the exposed rivets, screws or buckle structures are easy to be violently disassembled or damaged by tools such as crowbars and wrenches, resulting in the theft of the tag together with the asset identification information carried by the tag, causing unnecessary losses. SUMMARY

[0005] The purpose of the present application is to provide a metal metering box electronic tag to solve the problems raised in the background.

[0006] In order to achieve the above purpose, the present application provides the following technical scheme: a metal metering box electronic tag, comprising a support box and a protection box, a plurality of rivet holes are formed on the surface of the protection box, and the support box is connected to the protection box through the rivets in the rivet holes, a tag body and a protection cover plate for protecting the tag body are arranged in the protection box, a fixing plate is arranged on the side of the support box away from the protection box, a sliding rod is arranged in the fixing plate, one end of the sliding rod in the support box is fixedly connected with a mounting block, the tag body is connected with the mounting block, and the position of the tag body in the support box and the protection box is switched by sliding the sliding rod. A trigger assembly is arranged for retracting the tag body, when the trigger assembly is triggered, the tag body is pulled back into the support box. A protective component used to further protect the retracted tag body.

[0007] Preferably, the triggering component includes a tension spring, with its two ends fixedly connected to a mounting block and a fixing plate, respectively. A stepper motor is fixedly connected to the surface of the fixing plate, and a cam is fixedly connected to the output end of the stepper motor. A circular block adapted to the cam is fixedly connected to the end of the slide rod located outside the support box.

[0008] Preferably, a vibration sensor for detecting abnormal vibrations is installed inside the support box, and the vibration sensor is electrically connected to the stepper motor.

[0009] Preferably, the protective component includes several baffles hinged to the inner wall of the support box. A torsion spring is provided at the hinge point between the baffle and the support box. Under normal conditions, the rebound force of the torsion spring causes the baffle to press tightly against the surface of the label body.

[0010] Preferably, the inner wall of the support box is fixedly connected with a plurality of limiting blocks for limiting the rotation angle of the baffle.

[0011] Preferably, one end of the rivet that penetrates into the support box is provided with a collapse block, the collapse block is a plastic deformation metal, and one end of the rivet is provided with an expansion part. When the rivet is driven into the support box and the expansion part expands and is fixed, the expansion part is tightly pressed against one side of the collapse block.

[0012] Preferably, the surface of the collapse block is provided with collapse grooves.

[0013] Preferably, the surface of the fixing plate is provided with screw holes that extend into the interior of the support box.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the cooperation of a vibration sensor and a triggering component, promptly pulls the tag body back deep into the rear support box for protection when it detects vibrations caused by abnormal prying or damage. Since the opening at the connection between the support box and the protective box is small and about the same size as the tag body, it is difficult to steal the tag body from the support box, thus effectively improving the anti-theft performance of the electronic tag.

[0015] Furthermore, by setting up a protective component, the collapsible block that cooperates with the rivet will collapse when the protective box is forcibly pulled out. As the rivet is pulled outward, the collapsible area will undergo irreversible deformation and invade the return position of the baffle, thus rigidly fixing the baffle. The baffle blocks in front of the tag body, further preventing thieves from taking out the electronic tag, effectively strengthening the anti-theft measures and improving security.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] An electronic tag for a metal measuring box is disclosed in this embodiment of the invention, such as... Figures 1-5As shown, the device includes a support box 1 and a protective box 2. The support box 1 is pre-installed on the surface of the metal metering box. The protective box 2 has several rivet holes 21 on its surface, and is connected to the support box 1 through rivets 211 inside the rivet holes 211. After the support box 1 is installed with the metal metering box, its surface is smooth and flat, without any other extra holes, only the rivet holes 211 for connecting with the protective box 2. These rivet holes 211 are covered after the support box 1 and the protective box 2 are connected, enhancing the anti-theft performance of the support box 1. The protective box 2 contains a label body 3 and a protective cover 22 for protecting the label body 3. The protective cover 22 is a transparent glass cover or a transparent acrylic cover, selected according to factors such as the installation location and environment of the metal metering box. The protective cover 22 ensures that the label can be read and written normally while also providing conventional protection for the label. The support box 1 is located away from the protective box 2. A fixing plate 11 is provided on the side, and the fixing plate 11 is fixedly connected to the support box 1 by welding or other means. The fixing plate 11 is used to directly adhere to the metal measuring box and install the support box 1 on the surface of the metal measuring box. A sliding rod 311 is provided inside the fixing plate 11. An installation block 31 is fixedly connected to one end of the sliding rod 311 inside the support box 1. The label body 3 is connected to the installation block 31. The label body 3 can be connected to the installation block 31 by means of pasting, bolt fastening, or snap-fit, depending on different environments. By sliding the sliding rod 311, the label body 3 can switch positions between the support box 1 and the protective box 2. A trigger component is used to retract the label body 3. When the trigger component is triggered, the label body 3 is pulled back into the support box 1. A protective component is used to further protect the pulled-back label body 3.

[0020] Specifically, when installing the support box 1, a pre-drilled hole must first be made on the surface of the metal metering box to leave space for the sliding rod 311 to slide. Then, the support box 1 is fixedly installed on the surface of the metal metering box by the fixing plate 11, and the protective box 2 is nailed into the surface of the support box 1 by the rivet 211 in the rivet hole 21, thus completing the installation.

[0021] In the event of theft due to abnormal prying, the triggering component is activated in time, pulling the tag body 3 located in the protective box 2 to the depth inside the support box 1 through the sliding of the slide bar 311. This makes it difficult for the thief to directly remove and steal the tag body 3 located inside the support box 1 even if the protective box 2 is completely pried open. Since the support box 1 only has a square hole of a similar size to the tag body 3 on its surface, and the tag body 3 is located deep inside the support box 1, it is difficult to steal and damage the tag body 3 in a short time, thus effectively improving the security and anti-theft performance of the tag body 3.

[0022] The triggering component includes a tension spring 313, with its two ends fixedly connected to the mounting block 31 and the fixing plate 11, respectively. A stepper motor 32 is fixedly connected to the surface of the fixing plate 11. The stepper motor 32 is located inside the metal metering box during installation to improve its safety. During installation, a hole needs to be made on the surface of the metal metering box to accommodate the stepper motor 32, and the stepper motor 32 can be directly powered through the internal circuit of the metal metering box. A cam 321 is fixedly connected to the output end of the stepper motor 32. A round block 312 adapted to the cam 321 is fixedly connected to the end of the slide rod 311 located outside the support box 1. In the normal state, that is, when the label body 3 is inside the protective box 2, the cam 321 abuts against the round block 312, and the tension spring 313 is in a stretched state.

[0023] Furthermore, a vibration sensor for sensing abnormal vibrations is installed inside the support box 1. The vibration sensor can be a resistive vibration sensor, a capacitive vibration sensor, or a displacement sensor or a velocity sensor, etc., depending on the vibration intensity and destructive force. The vibration sensor is electrically connected to the stepper motor 32, or it can be powered directly through the internal circuitry of the metal metering box.

[0024] Specifically, when theft occurs, the vibration generated by the thief prying open the protective box 2 or damaging the protective cover 22 will cause the vibration sensor to detect abnormal vibration signals and transmit the signals to the stepper motor 32. The stepper motor 32 is equipped with a controller, which controls the output of the stepper motor 32 according to the signal. The stepper motor 32 causes the cam 321 to rotate. After the cam 321 is displaced from the circular block 312, the circular block 312 is no longer blocked by the cam 321. Under the action of the rebound force of the tension spring 313, the mounting block 31 is pulled towards the support box 1, which in turn causes the slide rod 311 to slide in the fixed plate 11. The tag body 3 is promptly pulled back to the interior of the support box 1 for protection.

[0025] It is worth noting that a signal transmission module and an alarm module can also be installed in the support box 1. The signal transmission module and alarm module are integrated with the vibration sensor and electrically connected. When the vibration sensor detects abnormal vibration, it not only transmits the signal to the stepper motor 32, but also transmits the signal to the signal transmission module and the alarm module at the same time. This allows the signal transmission module to send the signal to the technicians in a timely manner, indicating that an abnormal theft has occurred. This enables the technicians to react in time and simultaneously sound an alarm, reminding and deterring the thieves and preventing further losses.

[0026] In this embodiment, the protective component includes several baffles 24 hinged to the inner wall of the support box 1. The baffles 24 are made of high-strength metal material, such as alloy steel plate, to improve resistance to damage. A torsion spring is provided at the hinge point between the baffles 24 and the support box 1. Under normal conditions, the rebound force of the torsion spring causes the baffles 24 to press tightly against the surface of the label body 3. Thus, when the label body 3 is pulled back and retracted to the depth inside the support box 1, under the action of the rebound force of the torsion spring, the baffles 24 will rotate synchronously toward the depth inside the support box 1, thereby blocking the surface of the label body 3 and providing further protection, making it difficult for thieves to steal or damage the label body 3 in a short period of time.

[0027] The inner wall of the support box 1 is fixedly connected with a number of limiting blocks 241 for limiting the rotation angle of the baffle 24. By setting the limiting blocks 241, the maximum rotation angle of the baffle 24 is limited so that it can be in the optimal angle for protecting the label body 3.

[0028] Furthermore, in this embodiment, a collapse block 23 is provided at one end of the rivet 211 that penetrates into the support box 1. The collapse block 23 is made of a plastic deformation metal, such as a plastic aluminum alloy or stainless steel. The interior of the collapse block 23 can be hollow to facilitate plastic deformation. An expansion portion 212 is provided at one end of the rivet 211. When the rivet 211 is driven into the support box 1 and the expansion portion 212 expands and is fixed, the expansion portion 212 presses tightly against one side of the collapse block 23. The expansion portion 212 is formed by the normal deformation of the end of the rivet 211 for the purpose of fastening. This is a conventional technology for existing rivets 211, and its working principle will not be described in detail here.

[0029] Specifically, when the thief pries open the protective box 2, he will simultaneously pull outward on the rivet 211, causing the rivet 211 to deform and the expansion part 212 to exert a squeezing force on the collapse block 23. Under the action of this squeezing force, the collapse block 23 deforms as a whole, expanding its lateral area. The expanded lateral area squeezes into the return position of the baffle 24, fixing the baffle 24 and preventing it from returning to its original position. In this way, the thief cannot open the gap by rotating the baffle 24 outward, and thus steal the tag body 3.

[0030] Furthermore, the surface of the collapse block 23 is provided with a collapse groove 231. When the rivet 211 is pulled outward, when the expansion part 212 squeezes the collapse block 23, an extremely high stress concentration is formed at the root of the groove opening of the collapse groove 231. Plastic deformation will preferentially start from these sharp notches and extend along the direction of the groove opening. The direction of the groove opening is the return position of the baffle 24. By setting the collapse groove 231, the collapse direction of the collapse block 23 is effectively guided, making it easier for the baffle 24 to be blocked by the deformation intrusion process of the collapse block 23, thereby achieving the effect of effectively fastening the baffle 24.

[0031] The surface of the fixing plate 11 is provided with screw holes 12, which extend into the interior of the support box 1. When installing the support box 1, a hole is drilled from the inside of the metal metering box, and a fastening bolt is inserted from the inside of the metal metering box into the screw holes 12 on the surface of the fixing plate 11 and tightened. Alternatively, the support box 1 can be fixed to the metal metering box by external welding, which further improves the anti-damage performance of the support box 1.

[0032] Since the protective box 2 is fixed by rivets 211, while the support box 1 is fixed by multiple fastening bolts, it is more difficult to pry open the support box 1 than the protective box 2. It is even more difficult to obtain the electronic tag by directly prying off the support box 1, thus effectively improving the anti-vandalism and anti-theft performance.
