Description

Technical Field

[0001] This utility model relates to the technical field of handheld RFID reading devices, specifically a handheld RFID reading device. Background Technology

[0002] Animal ear tags are specialized identifiers attached to the ears of livestock, poultry, and other animals. Their core function is to enable individual animal identification and traceability management throughout the entire lifecycle. They are key tools for animal disease prevention and food safety supervision. Common animal ear tags fall into two categories. One type is the visual ear tag, which uses laser engraving to print numbers or QR codes, allowing basic information to be identified with the naked eye. The other type is the electronic ear tag, which has a built-in chip and requires specialized equipment for scanning. It can store more detailed dynamic data and is suitable for large-scale farming scenarios. Reading electronic ear tags often requires the use of handheld RFID readers.

[0003] Traditional handheld RFID readers use a one-piece injection molding process for the control box assembly and the grip. There is no angle adjustment mechanism between the control box assembly and the grip, so the grip angle of the handheld RFID reader cannot be selected according to the actual situation, resulting in poor practicality. Furthermore, the RFID reader extension rod assembly of existing handheld RFID readers has not been designed to reduce weight, which can cause hand fatigue when held for a long time. Summary of the Invention

[0004] In view of the shortcomings of the prior art, this utility model provides a handheld RFID reading device to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a handheld RFID reading device, comprising a control box assembly, an RFID reading extension rod assembly, and a handle. The control box assembly has an RFID reading extension rod assembly and a handle respectively at its front and rear ends. A connecting assembly is provided between the handle and the control box assembly. A tailstock is provided at the end of the handle furthest from the control box assembly, and a hanging rope is provided on the outside of the tailstock. A cap is fitted onto the end of the RFID reading extension rod assembly furthest from the control box assembly. A connecting wire is provided inside the RFID reading extension rod assembly. An animal ear tag RFID reading head is provided at the end of the connecting wire furthest from the control box assembly, and a connector is provided at the end of the connecting wire closest to the control box assembly. The RFID reading extension rod assembly includes an extension rod body, the extension rod body has equally spaced grooves inside, the extension rod body has equally spaced wire seats installed inside, the wire seats have wire grooves on their central axis, and the end of the extension rod body facing the control box assembly is provided with a threaded sleeve. The connecting assembly includes a connecting seat, with annular grooves on both sides of the connecting seat and a through hole on the transverse axis of the connecting seat. The end of the grip facing the control box assembly has a snap-fit ​​groove, and an annular ring adapted to the annular groove is fixedly installed inside the snap-fit ​​groove. The side of the grip has a through hole with the same diameter as the through hole. A locking bolt and a locking nut are also provided between the grip and the connecting seat.

[0006] Preferably, the control box assembly includes a control box housing and a cover plate. A sealing strip is provided on the side of the cover plate facing the control box housing. A sealing groove is provided at the opening at the top of the control box housing. A threaded post is fixedly installed on the end of the control box housing facing the RFID reading extension rod assembly. The control box housing and the cover plate are detachably connected by fastening bolts.

[0007] The above technical solution utilizes the sealing strip and sealing groove between the cover plate and the control box housing to form a double sealing structure, effectively isolating external dust, moisture and other impurities. This provides a stable protective environment for the core electronic components such as the circuit board and 4G module inside the control box, preventing components from malfunctioning due to moisture or contamination. The detachable connection achieved by the fastening bolts facilitates the later inspection, maintenance or upgrade of the components inside the control box, significantly reducing the maintenance cost and difficulty of the equipment.

[0008] Preferably, the threaded post and the threaded sleeve are connected by threads, the sealing strip and the sealing groove are connected by plug-in connection, and the sealing strip is made of rubber.

[0009] Through the above technical solutions, the threaded connection design of the threaded column and the threaded sleeve makes the assembly and disassembly of the RFID reading extension rod assembly and the control box assembly more convenient. The rubber sealing strip and the sealing groove adopt a plug-in fit, and the elastic deformation characteristics of rubber are used to fill the sealing gap, further improving the sealing reliability of the control box assembly. At the same time, the rubber sealing strip is resistant to aging and wear, and can maintain a good sealing effect for a long time, ensuring the service life of the equipment in complex environments.

[0010] Preferably, the grooves are provided in multiple identical shapes, the extension rod body is made of plastic, the wire seat and the extension rod body are integrally injection molded, and the connecting wire and the wire groove are plug-in connected.

[0011] Through the above technical solutions, the extension rod body is made of plastic and the groove 202 is opened, which can significantly reduce the overall weight of the equipment, reduce the burden on the operator when holding it, and improve the comfort of long-term use. The integrated injection molding process of the wire seat and the extension rod body enhances the structural connection strength of the two and prevents the wire seat from falling off or shifting during use.

[0012] Preferably, the number of annular rings and annular grooves is the same, the annular rings and annular grooves are rotatably connected, the handle is sleeved on the outside of the connecting seat, the locking bolt passes through through hole one and through hole two and extends to the outside of the handle, and the transverse axes of the annular rings, annular grooves, through hole one and through hole two are all on the same straight line.

[0013] The above technical solution, with its rotating connection design between the annular ring and the annular groove, allows the handle to be flexibly adjusted around the connecting seat. Operators can hold it horizontally or at a 90° angle according to different gripping postures, meeting the needs of different environments.

[0014] Preferably, the control box housing contains a circuit board, a 4G module, and a GPS module, and the circuit board and the connecting cable are connected by telecommunications.

[0015] Through the above technical solution, the circuit board inside the control box serves as the core control unit. By establishing a telecommunications connection with the connecting cable, it can receive tag data transmitted by the animal ear tag RFID reader in real time, and process and store the data. The 4G module enables wireless data interaction between the device and a remote server, supports real-time uploading of read data, and facilitates unified data management. The GPS module can accurately record the device's location information, enabling traceability of RFID tag reading locations. The collaborative work of these three components significantly improves the device's functional completeness and meets the needs of scenarios such as outdoor mobile reading and real-time data synchronization.

[0016] Preferably, a silicone sleeve is provided on the outside of the grip, and the axes of the grip, the RFID reading extension rod assembly and the cap are located on the same horizontal line.

[0017] Through the above technical solutions, the silicone sleeve on the outside of the grip can increase the friction between the hand and the grip, effectively preventing the device from slipping when held. At the same time, the soft and skin-friendly silicone material can relieve hand fatigue caused by prolonged holding and improve the comfort of use. The axes of the grip, RFID reading extension rod assembly and the cap are kept on the same horizontal line, making the overall structure of the device neat and the center of gravity more stable when held, avoiding operation tilting due to axis offset, ensuring that the animal ear tag RFID reading head can accurately align with the tag, and improving reading efficiency and accuracy.

[0018] Compared with the prior art, the present invention provides a handheld RFID reading device, which has the following advantages: 1. This handheld RFID reader features a handle that rotates between a ring and a connecting seat, allowing for flexible adjustment of the grip angle, such as horizontal or 90°, to accommodate different operating environments and user preferences. The extension rod, made of plastic with grooves, significantly reduces the overall weight of the device and alleviates the burden of prolonged hand use. The integrated injection molding of the lead wire seat and the rod enhances structural stability and prevents the lead wire seat from falling off or shifting. The silicone sleeve on the outside of the handle provides anti-slip properties and reduces hand fatigue. Furthermore, the handle, extension rod, and cap are aligned to ensure a stable center of gravity during hand use, improving the alignment accuracy of the RFID reader head for animal ear tags and guaranteeing reading efficiency.

[0019] 2. This handheld RFID reader features a control box assembly with a double seal formed by a sealing strip and sealing groove between the cover and the housing. Combined with an aging-resistant rubber sealing strip, it effectively isolates dust and moisture, providing stable protection for core components such as internal circuit boards. The threaded connection design of the threaded column and threaded sleeve, as well as the detachable structure of the cover, facilitates the disassembly and assembly of the RFID reader extension rod assembly and the control box, and also reduces the difficulty and cost of later inspection and maintenance. The overall design takes into account lightweight, structural stability and functional integrity, which greatly improves the device's adaptability and practical value while reducing the burden of operation.

At the same time, the rubber sealing strip 104 is resistant to aging and wear, maintaining a good sealing effect for a long time and ensuring the service life of the equipment in complex environments.

[0027] Example 3: like Figure 2-8 As shown, as an improvement to the previous embodiment, this is done to reduce the burden on the operator when holding the device.

[0028] Specifically, multiple identical grooves 202 are provided. The extension rod body 201 is made of plastic. The wire seat 203 and the extension rod body 201 are integrally injection molded. The connecting wire 9 is plugged into the wire groove 204. The advantages are that the use of plastic for the extension rod body 201 and the presence of the grooves 202 significantly reduce the overall weight of the equipment, lessening the burden on the operator's hand and improving comfort during extended use. The integral injection molding process of the wire seat 203 and the extension rod body 201 enhances the structural connection strength between the two, preventing the wire seat 203 from detaching or shifting during use.

[0029] Example 4: like Figure 2-8 As shown, this is an improvement on the previous embodiment, designed to meet the needs of use in different environments.

[0030] Specifically, the number of annular rings 405 and annular grooves 402 is the same, and the annular rings 405 and annular grooves 402 are rotatably connected. The handle 5 is sleeved on the outside of the connecting seat 401. The locking bolt 407 passes through through hole one 403 and through hole two 406 and extends to the outside of the handle 5. The transverse axes of the annular rings 405, annular grooves 402, through hole one 403, and through hole two 406 are all on the same straight line.

The operator can hold it horizontally or at 90° according to different gripping postures to meet the needs of different environments.

[0031] Example 5: like Figure 2-8 As shown, as an improvement to the previous embodiment, this is done to meet the needs of scenarios such as outdoor mobile reading and real-time data synchronization.

[0032] Specifically, the control box housing 101 internally houses a circuit board 11, a 4G module 12, and a GPS module 13. The circuit board 11 is connected to the connecting cable 9 via telecommunications. The advantages are that the circuit board 11 inside the control box housing 101, acting as the core control unit, can receive tag data transmitted from the animal ear tag RFID reader 10 in real time through the telecommunications connection with the connecting cable 9, and process and store the data.

The collaborative work of these three modules significantly enhances the device's functional completeness, meeting the needs of outdoor mobile reading and real-time data synchronization scenarios.

[0033] Example 6: like Figure 2-8 As shown, as an improvement to the previous embodiment, in order to improve reading efficiency and accuracy.

[0034] Specifically, a silicone sleeve is provided on the outside of the grip 5, and the axes of the grip 5, the RFID reading extension rod assembly 2, and the cap 3 are located on the same horizontal line. The advantages are that the silicone sleeve on the outside of the grip 5 increases the friction between the hand and the grip 5, effectively preventing the device from slipping when held.

The internal integrated injection-molded wire seat 203 fixes the connecting wire 9 through the wire groove 204. Simultaneously, the angle of the handle 5 can be adjusted according to grip habits and scenarios using the annular ring 405 and annular groove 402 of the connecting assembly 4, and then fixed with the locking bolt 407. The silicone sleeve of the handle 5 is non-slip, and the plastic material of the extension rod and the groove design 202 reduce the burden on the hand. Then, the data reading stage begins. The operator holds the device and aligns the animal ear tag RFID reader 10 with the target tag to read the data. The head receives the RFID tag's radio frequency signal and converts it into an electrical signal, which is then stably transmitted to the circuit board 11 via the connecting line 9. The circuit board 11 then parses, verifies, and stores the raw data. The 4G module 12 uploads the processed data to a remote server in real time for synchronous management. The GPS module 13 synchronously collects the device's location information and associates it with the tag data to achieve traceability. During continuous operation, the control box's sealed structure isolates external impurities, and the lightweight design and optimized grip 5 reduce fatigue. The integrated wire seat 203 and bolt fixation ensure structural stability, ultimately achieving efficient and accurate reading of RFID tags and full-process data management.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
