[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-6 As shown, a double-sided rotating NFC card includes an NFC card plate 1, which includes a right half plate 2 and a left half plate 3 that are movably assembled into one piece. Slots are provided in both the right half plate 2 and the left half plate 3, and the slots form a combination groove 8.

[0030] The shielding plate 7 is inserted into the combination slot 8;

[0031] Slide rods 5 are fixedly installed on different sides of the left half plate 3 and the right half plate 2 respectively, and the slide rods 5 are located in the center of the adjacent surfaces of the left half plate 3 and the right half plate 2;

[0032] Slide 5 is used to assemble NFC card plate 1.

[0033] Specifically, bearings 6 are provided on both the left half plate 3 and the right half plate 2, and the bearings 6 are provided with elastic elements for maintaining a predetermined height. When assembling the above device, firstly, the shielding plate 7 is inserted into the slot on the left half plate 3 or the right half plate 2. Then, the corresponding other half plate is assembled with the inserted left half plate 3 or the right half plate 2 to form a whole. At this time, the shielding plate 7 is located in the combination groove 8 formed between the two half plates, making the shielding plate 7 easy to disassemble and replace. Then, the two NFC card plates 1 are slidably inserted into the slide bars 5 on different sides, so that the NFC card plates 1 are rotatably positioned on the upper and lower sides of the device. The shielding plate 7 shields and blocks the two NFC card plates 1. In use, the required NFC card is brought close to the receiving device. At this time, the shielding plate 7 shields the other NFC card, preventing information misreading.

[0034] Furthermore, the bearing 6 allows both sides of the NFC card plate 1 to rotate, increasing the fun of using the device.

[0035] In the above technology, the two NFC card plates 1 are shielded and isolated by the shielding plate 7 to prevent information misreading. Moreover, the shielding plate 7 is easy to install and remove, and can be easily replaced if damaged, thus improving the service life of the device. Furthermore, the bearing 6 allows both NFC card plates 1 to rotate, increasing the fun of using the device.

[0036] As a further embodiment of this utility model, a transmission member 4 is slidably disposed on both the left half plate 3 and the right half plate 2, and a card member 41 for engaging the NFC card plate 1 is disposed at the end of the transmission member 4.

[0037] Specifically, the transmission component 4 is slidably arranged along the left half plate 3 or the right half plate 2, and an annular card slot 11 is opened in the NFC card plate 1. The card 41 on the transmission component 4 slides in the slide rod 5, and the end of the card 41 extends out of the slide rod 5 and engages with the card slot 11. When the NFC card plate 1 needs to be removed, the transmission component 4 is pushed in the direction of the slide rod 5, so that the transmission component 4 drives the card 41 away from the card slot 11. At this time, the transmission component 4 is disengaged from the NFC card plate 1, and the disassembly and assembly operations can be performed.

[0038] Furthermore, since the transmission component 4 has a rectangular opening, and the width of the rectangular opening is greater than that of the shielding plate 7, and the combined groove 8 is located inside the opening, the sliding process of the transmission component 4 will not interfere with the shielding plate 7.

[0039] As a further embodiment of this utility model, a locking assembly is provided on the adjacent surfaces of the left half plate 3 and the right half plate 2, the locking assembly including:

[0040] The sliding locking lever 9;

[0041] Locking element 94 is inserted and engaged with locking rod 9;

[0042] Spring 91 used for pushing the locking lever 9.

[0043] Specifically, a locking assembly consisting of a locking rod 9, a locking component 94, and a spring 91 is provided on the adjacent surfaces of the left half plate 3 and the right half plate 2, and the two locking assemblies are centrally symmetrically distributed on the horizontal plane, so that the locking rods 9 of different groups correspond to the locking components 94. When assembling the left half plate 3 and the right half plate 2, the locking rod 9 will first abut against the locking component 94 of the other group, and the locking rod 9 will be guided by the inclined surface. Since the adjacent surfaces of the left half plate 3 and the right half plate 2 are provided with sliding grooves 93 for the locking rod 9 to slide, the sliding path of the locking rod 9 is fixed. At this time, the spring 91 contracts until the locking rod 9 slides into the through hole in the locking component 94, the spring 91 is released, and the locking rod 9 is pushed into the locking component 94, thus realizing the assembly of the left half plate 3 and the right half plate 2.

[0044] As another embodiment of this utility model, the locking rod 9 is provided with a wedge 92 at its end, and the transmission member 4 is provided with a transmission rod 42 that slides with the wedge 92. When the transmission rod 42 is tangent to the wedge 92, the spring 91 contracts.

[0045] Specifically, the transmission component 4 is pushed in the direction of the slide rod 5. The transmission component 4 drives the transmission rod 42 to abut against the inclined surface of the inclined block 92. The inclined block 92 slides under the guidance of the transmission rod 42. At this time, the sliding direction of the inclined block 92 is opposite to the pushing direction of the spring 91, causing the spring 91 to contract. The inclined block 92 drives the locking rod 9 to be misaligned with the locking component 94. The locking component 94 and the locking rod 9 are disengaged, and the left half plate 3 and the right half plate 2 can be separated.

[0046] Furthermore, the locking member 94 has a certain thickness, which allows the locking rod 9 to slide a distance without disengaging from the locking member 94. When the transmission member 4 slides a short distance towards the slide bar 5, it can drive the card 41 to disengage from the card slot 11, and keep the locking rod 9 within the locking member 94, so that the NFC card plate 1 can be removed separately.

[0047] Working principle: When assembling the left half plate 3 and the right half plate 2, first insert the shielding plate 7 into the slot on the left half plate 3 or the right half plate 2. The locking rod 9 first abuts against the locking part 94 of another set, and the locking rod 9 is guided by the inclined surface. At this time, the spring 91 contracts until the locking rod 9 slides into the through hole in the locking part 94. Then the spring 91 is released, and the locking rod 9 is pushed into the locking part 94, realizing the assembly of the left half plate 3 and the right half plate 2. Then, the NFC card plate 1 is slidably inserted along the slide rod 5. The end of the card part 41 extends out of the slide rod 5 and engages with the card slot 11, completing the overall assembly.

[0048] When it is necessary to remove the NFC card plate 1, push the transmission component 4 in the direction of the slide bar 5, so that the transmission component 4 moves the card 41 away from the card slot 11. Because the sliding distance is short, the locking bar 9 is still inside the locking component 94, so the NFC card plate 1 can be removed separately. When it is necessary to remove the left half plate 3 and the right half plate 2, increase the sliding distance of the transmission component 4 in the direction of the slide bar 5. The transmission component 4 drives the transmission rod 42 to abut against the inclined surface of the inclined block 92. The inclined block 92 slides under the guidance of the transmission rod 42. At this time, the sliding direction of the inclined block 92 is opposite to the pushing direction of the spring 91, so that the spring 91 contracts. The inclined block 92 drives the locking bar 9 to be misaligned with the locking component 94. The locking component 94 and the locking bar 9 are disengaged, and the left half plate 3 and the right half plate 2 can be removed.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
