Description

Technical Field

[0001] This utility model relates to the field of identity recognition terminal technology, and in particular to an RFID-based fire protection vocational skills assessment identity recognition terminal. Background Technology

[0002] In fire protection vocational skills assessment scenarios, ensuring accurate identification of candidates is crucial. Identification terminals, as key equipment, generally consist of electronic tags, readers, and a back-end management system. Among them, RFID (Radio Frequency Identification) technology is widely used in the field of identification due to its non-contact automatic identification and convenient data reading and writing characteristics. Electronic tags store candidates' key identity information, and readers can quickly read the tag content and transmit it to the back-end system for comparison and verification, greatly improving the efficiency and accuracy of identification and providing strong support for the orderly conduct of fire protection vocational skills assessment.

[0003] However, current traditional portable handheld identification terminals have revealed some problems that urgently need to be solved in actual use. These terminals generally lack a protective structure for the screen. If they are accidentally bumped during use, the screen of the terminal will be easily damaged, affecting the smoothness of data display and operation. In addition, if the staff accidentally drops the terminal during the busy identification process, it will be damaged due to the violent impact, thus causing equipment failure. Utility Model Content

[0004] In view of the problems mentioned above, the existing traditional portable handheld identification terminals lack a screen protection structure and are easily damaged by collisions, and the terminal may be accidentally dropped and broken by the staff during use, so this utility model is proposed.

[0005] To solve the above technical problems, this utility model provides the following technical solution: an RFID-based fire protection vocational skills assessment identification terminal, including an identification terminal body, a protective soft cover on the front of the identification terminal body, and the upper end of the protective soft cover is hinged to the top of the identification terminal body through a connecting mechanism, and a fixing mechanism is provided on the back of the identification terminal body;

[0006] The fixing mechanism includes a limiting seat, which is fixedly installed on the lower back of the identity recognition terminal body. An adjustment groove is provided on the side wall of the limiting seat away from the identity recognition terminal body. A sliding plate is slidably installed in the adjustment groove. The top of the sliding plate is fixedly connected to the top wall of the adjustment groove by several springs. The bottom of the sliding plate is symmetrically provided with limiting posts. A number of limiting holes adapted to the limiting posts are provided on one side of the protective soft cover. An adjustment rod connected to the sliding plate is provided at the end of the limiting seat away from the identity recognition terminal body.

[0007] As a preferred embodiment, the limiting seat has a U-shaped structure and is fixedly connected to the identity recognition terminal body. The protective soft cover has a rubber pad connected to the side of the front of the identity recognition terminal body.

[0008] As a preferred embodiment, a soft magnetic strip is embedded in the lower end of the protective soft cover near the side wall of the rubber pad, and the soft magnetic strip is magnetically connected to the lower front end of the identity recognition terminal body.

[0009] As a preferred embodiment, protective blocks are fitted at all four corners of the identity recognition terminal body, and the protective blocks are made of rubber.

[0010] As a preferred embodiment, the connecting mechanism includes a first fixed seat and a second fixed seat, and the first fixed seat and the second fixed seat are symmetrically arranged on the top of the identity recognition terminal body near the back of the identity recognition terminal body. A connecting shaft is hinged to the inner side of the first fixed seat, and one end of the connecting shaft is located inside the second fixed seat. The upper end of the protective soft cover is rotatably sleeved on the outer side of the connecting shaft. A limiting component for limiting the position of the connecting shaft is provided on one side of the second fixed seat.

[0011] As a preferred embodiment, the limiting component includes a stop block. A cavity is symmetrically formed inside the second fixed base. The stop block is slidably installed in the cavity. A support rod is fixedly connected to one end of the stop block away from the fixed base. A spring is sleeved on the outside of the support rod, and the two ends of the spring are fixedly connected to the stop block and the inner wall of the cavity, respectively. The ends of the two support rods away from the stop block extend to the outside of the second fixed base and are connected to a connecting block. A limiting block is fixedly connected to one side of the connecting block, and the limiting block is located above the connecting shaft. One end of the limiting block extends to the inside of the second fixed base.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] 1. This utility model uses a protective soft cover and rubber pad to cover and protect the terminal's display screen, preventing accidental collisions or scratches. With the fixing mechanism, the protective soft cover can be flipped over during use, and the adjusting rod can be pulled to move the sliding plate and limiting post into the adjusting groove. Then, one end of the protective soft cover passes through the inner side of the limiting seat, and the limiting post and the limiting hole on the protective soft cover are used to adjust the tightness of the protective soft cover according to actual usage. This allows the terminal to be fixed to the user's hand or arm, solving the problem of staff accidentally dropping the terminal during busy testing processes, causing damage due to severe impact, and ultimately leading to equipment failure.

[0014] 2. This utility model, through a connecting mechanism, allows for a hinged connection between the identity recognition terminal body and the protective soft cover, enabling the protective soft cover to be flipped. Combined with a limiting component, the protective soft cover can be easily disassembled and replaced. By pulling the connecting block, the limiting block and support rod are moved out of the second fixing seat. Simultaneously, the support rod drives the stop block to press against the support rod, thus moving one end of the connecting shaft out of the second fixing seat, allowing the protective soft cover to be removed and replaced. When installing the protective soft cover, simply repeat the above steps: after moving one end of the connecting shaft into the second fixing seat, the spring force of the second spring resets the limiting block, thereby limiting the connecting shaft and completing the fixation.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1 - Figure 5As shown, an RFID-based fire protection vocational skills assessment identification terminal is provided, including an identification terminal body 1. The front of the identification terminal body 1 is provided with a protective soft cover 3, and the upper end of the protective soft cover 3 is hinged to the top of the identification terminal body 1 through a connecting mechanism. The back of the identification terminal body 1 is provided with a fixing mechanism; the flexible connection and fixing function of the protective soft cover 3 and the terminal are realized, laying the foundation for subsequent protection and fixing operations.

[0024] The fixing mechanism includes a limiting seat 4, which is fixedly installed on the lower back of the identity recognition terminal body 1. An adjustment groove 5 is provided on the side wall of the limiting seat 4 away from the identity recognition terminal body 1. A sliding plate 6 is slidably installed in the adjustment groove 5. The top of the sliding plate 6 is fixedly connected to the top wall of the adjustment groove 5 by several springs 8. The bottom of the sliding plate 6 is symmetrically provided with limiting posts 7. A number of limiting holes 10 adapted to the limiting posts 7 are provided on one side of the protective soft cover 3. An adjustment rod 9 connected to the sliding plate 6 is provided at the end of the limiting seat 4 away from the identity recognition terminal body 1. The limiting posts 7 and the limiting holes 10 are engaged by the elastic action of the springs 8. The tightness of the fixing can be flexibly adjusted with the adjustment rod 9, which improves the stability and adaptability of the terminal fixing.

[0025] In this example, the limiting seat 4 has a U-shaped structure and is fixedly connected to the identity recognition terminal body 1. The protective soft cover 3 is connected to a rubber pad 11 on the side near the front of the identity recognition terminal body 1. The U-shaped structure facilitates the passage and limiting of the protective soft cover 3, and the rubber pad 11 enhances the buffering and protection effect of the protective soft cover 3 on the screen, reducing collision damage.

[0026] In this example, a soft magnetic strip 21 is embedded in the side wall of the lower end of the protective soft cover 3 near the rubber pad 11, and the soft magnetic strip 21 is magnetically connected to the lower end of the front of the identity recognition terminal body 1; the magnetic attraction makes the protective soft cover 3 fit tightly against the front of the terminal when not in use, so as to avoid accidental opening and exposure of the screen.

[0027] In this example, protective blocks 2 are installed on all four corners of the identity recognition terminal body 1, and the protective blocks 2 are made of rubber. The rubber protective blocks 2 can absorb the impact force when the terminal is dropped, focusing on protecting the vulnerable four corner parts and reducing the probability of equipment damage.

[0028] In this example, the connecting mechanism includes a first fixing seat 12 and a second fixing seat 13, which are symmetrically arranged on the top of the identity recognition terminal body 1 near the back of the identity recognition terminal body 1. A connecting shaft 14 is hinged to the inner side of the first fixing seat 12, and one end of the connecting shaft 14 is located inside the second fixing seat 13. The upper end of the protective soft cover 3 is rotatably sleeved on the outer side of the connecting shaft 14. A limiting component for limiting the connecting shaft 14 is provided on one side of the second fixing seat 13. The connecting shaft 14 enables the flipping function of the protective soft cover 3, and the limiting component ensures the stable installation of the connecting shaft 14, thus balancing the mobility and connection reliability of the protective soft cover 3.

[0029] In this example, the limiting component includes a stop block 16. A cavity 15 is symmetrically opened inside the second fixed base 13. The stop block 16 is slidably installed in the cavity 15. A support rod 17 is fixedly connected to the end of the stop block 16 away from the first fixed base 12. A second spring 18 is sleeved on the outside of the support rod 17, and the two ends of the second spring 18 are fixedly connected to the stop block 16 and the inner wall of the cavity 15, respectively. The ends of the two support rods 17 away from the stop block 16 extend to the outside of the second fixed base 13 and are connected to a connecting block 19. A limiting block 20 is fixedly connected to one side of the connecting block 19, and the limiting block 20 is located above the connecting shaft 14. One end of the limiting block 20 extends to the inside of the second fixed base 13. The elastic force of the second spring 18 realizes the automatic limiting of the connecting shaft 14 by the limiting block 20. The limiting component can be easily operated through the connecting block 19, which facilitates the quick disassembly and replacement of the protective soft cover 3 and improves the equipment maintenance efficiency.

[0030] The working principle of this utility model is as follows: When not in use, the protective soft cover 3 is magnetically connected to the lower front end of the identity recognition terminal body 1 through the soft magnetic strip 21, forming a cover and protection for the terminal screen. The rubber pad 11 further enhances the buffering effect and prevents the screen from being damaged by accidental collisions or scratches.

[0031] When using the terminal, release the magnetic attraction of the soft magnetic strip 21, flip the protective soft cover 3, and rotate it around the connecting shaft 14 of the connecting mechanism to a suitable position; pull the adjusting rod 9 to move the slide plate 6 in the adjusting groove 5, the spring 8 is compressed, and the limiting post 7 moves into the adjusting groove 5. Pass one end of the protective soft cover 3 through the inside of the limiting seat 4 of the U-shaped structure, release the adjusting rod 9, and under the elastic force of the spring 8, the slide plate 6 moves down, and the limiting post 7 is inserted into the corresponding limiting hole 10 on the protective soft cover 3. Select the appropriate limiting hole 10 according to the actual use needs to adjust the tightness of the protective soft cover 3, thereby fixing the terminal on the user's hand or arm.

[0032] When it is necessary to remove or replace the protective soft cover 3, pull the connecting block 19 to move the support rod 17 and the stop block 16 within the cavity 15. The second spring 18 is compressed, and the limiting block 20 moves away from above the connecting shaft 14, releasing the limitation on the connecting shaft 14. Move one end of the connecting shaft 14 out from the inside of the second fixing seat 13, and the protective soft cover 3 can be removed. During installation, repeat the above steps. Place one end of the connecting shaft 14 inside the second fixing seat 13, release the connecting block 19, and under the elastic force of the second spring 18, the stop block 16 drives the support rod 17 and the connecting block 19 to reset. The limiting block 20 extends back to the inside of the second fixing seat 13 and is located above the connecting shaft 14, completing the limitation and fixation of the connecting shaft 14.

[0033] The rubber protective blocks 2 at the four corners of the identity recognition terminal body 1 can absorb the impact force when the terminal is accidentally dropped, focusing on protecting the four corners and further reducing the possibility of equipment damage.
