[0002] Radio frequency identification (RFID) cards are a powerful tool for realizing information management of containers. Information about the items inside the container can be written into the RFID card, and during transportation, information about the goods inside the container can be easily obtained by reading the information on the RFID card. RFID cards enable contactless information reading while the container is in motion, greatly improving the efficiency of information transmission. For example, patent document CN 203224901 U discloses an anti-theft and tampering system suitable for coal transportation, including: a lead-sealed security tag installed on the container; a lead-sealed security tag detector for detecting information on the aforementioned lead-sealed security tag; a computer connected to the lead-sealed security tag detector; and a remote terminal database server for managing coal transportation information. The lead-sealed security tag contains an RFID card that records coal transportation information, and the lead-sealed security tag detector is equipped with an electromagnetic wave sensor that senses the information recorded on the aforementioned RFID card. However, the secure fixation and convenient reading of RFID cards on containers have not been well resolved by this method.

Detailed Implementation
[0013] The following detailed description of the specific implementation of the present invention, in conjunction with preferred embodiments, is provided below: Referring to the accompanying drawings, this embodiment provides an installation and fixing device for a container RFID card, including a base 1, a slide 2, a clamping mechanism 3, and a pop-out mechanism 4. The base is connected to the slide, and the back of the slide has a groove 2-1. A clamping mechanism is installed in the groove, and the clamping mechanism includes a pull rod 3-1, a left clamping rod 3-2, a right clamping rod 3-3, a clamping spring 3-4, and a clamping claw 3-5. The groove has a support shaft circular hole 2-2 along its transverse centerline. A support shaft 2-3 is slidably connected in the support shaft circular hole. Spring sleeves 2-4 are fitted at both ends of the support shaft, and clamping springs are fitted on the spring sleeves. One end of each spring sleeve is hinged to the left and right clamping rods, respectively. The other ends of the left and right clamping rods are V-shaped and connected to one end of the pull rod. The system is hinged, with the other end of the pull rod supported in the pull rod support hole 1-1 of the base. The clamping claw is fixed to the spring sleeve at the left end. The slide 2 is connected to the pop-out mechanism, which includes a pop-out slide 4-1, a pop-out hanging rod 4-2, a locking slide 4-3, and a pop-out tension spring 4-4. The pop-out slide is supported on the base, and the slide 2 is slidably connected to the pop-out slide 4-1. By manually pulling the rod axially back and forth, the slide moves axially back and forth along the base. The pop-out tension spring 4-4 is hooked on the side of the slide, and the other end of the pop-out tension spring is hooked on the base through the hanging spring ear 4-4-1. The rear end of the pop-out hanging rod is inserted into the pivot hole of the base, and its front end slides along the locking slide 4-3. The locking slide includes a locking limiting groove 4-3-1 and a pop-out groove 4-3-2. The pop-out groove is lower than the locking limiting groove and is stepped, forming a slide locking / pop-out mechanism.
[0014] In a preferred embodiment, the front and rear ends of the pop-out hanging rod are respectively provided with arc-shaped bends.
[0015] In a preferred embodiment, the clamping claw is provided with an RFID card clamping platform 3-5-1, and the two ends of the RFID card clamping platform are provided with clamping buckles 3-5-2, which can fix RFID cards of different widths on the platform and prevent loosening and slippage caused by vibration during transportation.
[0016] In a preferred embodiment, the base is provided with a slide limit guide, which is fixedly connected to the base. A sliding groove is provided along the axial direction of the slide's side wall, and the sliding groove is slidably connected to the slide limit guide. The slide limit guide and the ejector slide constitute a guide rail structure for the axial movement of the slide. A slot is made in the middle of the slide's side, and the guide is embedded in the slot. The upper surface of the guide is lower than the slide to avoid interference between the guide and the card.
[0017] The working process is further explained in conjunction with the specific structure of this embodiment: The RFID card mounting and securing device consists of three main parts: a base, a clamping mechanism, and an ejection mechanism, all housed in an external casing. The base is fixed to the container or shelter by welding or riveting, and a dustproof and waterproof casing (not shown in the diagram) can be installed on the outside. The ejection mechanism allows the RFID cards to be ejected and inserted from the casing, while the clamping mechanism secures RFID cards of different widths on the card holder, preventing loosening and slippage caused by vibration during transportation.
[0018] See appendix for details Figure 3-6 , 1. Secure the card: The card fastening mechanism consists of a pull rod, left and right clamping rods, left and right clamping springs, and clamping claws. When the pull rod is pushed forward, it moves the left and right clamping rods to the left and right sides, causing the clamping claws to open and simultaneously compressing the left and right clamping springs. When the left and right clamping springs are compressed to their limit positions, the clamping claws are at their maximum open position. When the RFID card is inserted, continuing to push the pull rod will cause the slide 2 to slide forward along the axial direction of the base, causing the ejection spring 4-4 of the card ejection mechanism to open. At the same time, the bent head at the front end of the ejection hook of the ejection mechanism rotates in the pivot hole on the base, while the bent head at the rear end of the ejection hook slides along the locking slide 4-3. The bent head at the rear end of the ejection hook finally hooks onto the locking limit groove 4-3-1, causing the slide to enter the locking limit position. In the first state, the spring force of the pulled-out spring is transmitted through the locking limit groove to the pop-out hook 4-2, and then to the slide table with the card, so that the slide table is in the locked balance position. At this time, the pull rod is released, and the rebound force of the left and right springs of the card fastening mechanism can make the clamping claws clamp the RFID card. At this time, the card is in the left and right clamped state. When the pull rod is in the relaxed state, since the thickness of the RFID card is 0.8-1.8mm, which is less than the height of the clamping claws, and the card itself is very light, the card can be fastened in all directions of the slide table.
[0019] 2. Card pops out: When the card needs to be removed, push the pull rod. The left and right clamping rods compress the left and right clamping springs to their limit positions, causing the ejector slide to slide forward along the axial direction of the base. The front bent head of the ejector rod rotates in the pivot hole on the base, while the rear bent head slides along the locking slide 4-3. The rear bent head of the ejector rod eventually hooks onto the locking limit groove 4-3-1. Because the height of the ejector groove 4-3-2 is lower than the locking limit groove, the limiting balance of the rear bent head of the ejector rod at the locking limit groove 4-3-1 is disrupted, releasing the locking state of the slide. The return force of the ejector spring 4-4 causes the ejector rod to move along the ejector slide 4-1, allowing the slide to move forward to its limit position and then backward along the ejector slide. When the ejector position is reached, the clamping claws 3-5 are at their maximum opening, releasing the card. When the slide 2 moves to the ejector position, a small portion of the RFID card is exposed, allowing for easy removal. By coordinating the movement of the slide and the action of the clamping claw, the card is securely fixed and easily ejected.
[0020] The above detailed description of an installation and fixing device for a container RFID card, with reference to the embodiments, is illustrative rather than limiting. Several embodiments can be listed according to the defined scope. Therefore, changes and modifications without departing from the overall concept of this utility model should be within the protection scope of this utility model.
