[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, a single-sided rotating NFC card includes a card sleeve 1 and a fixing seat 4 inserted into the card sleeve 1;

[0028] An NFC card 3 movably disposed in a fixing seat 4;

[0029] A ball bearing for rotating the NFC card 3, comprising a ball 12 and a limiting ring 13 for limiting the ball 12, and an elastic member 14 for pushing the ball 12 to a predetermined height;

[0030] A clamping member 5 is slidably disposed in the clamping sleeve 1 and engaged with the fixing seat 4;

[0031] A locking member 15 for locking the clamping member 5 is fixedly provided on the elastic member 14 .

[0032] Specifically, the fixing seat 4 is a hollow structure, the ball bearing is fixedly arranged in the sleeve 1 and is located in the hollow part of the fixing seat 4, the ball 12 at a predetermined height is against the bottom surface of the NFC card 3, so that the NFC card 3 can rotate freely, and the card 5 is provided with a spring 52, and the card 5 is provided with a fastener 53 that engages with the locking member 15.

[0033] Furthermore, the fixing seat 4 can be made of a plastic material with a certain elasticity to achieve the engagement with the NFC card 3, and then the fixing seat 4 is sleeved in the card sleeve 1, and the fixing seat 4 is engaged through the card member 5. A card slot can be provided on the card member 5, and a protrusion that matches the card slot can be provided on the fixing seat 4 to achieve engagement, or a rubber pad can be provided on the card member 5, and the fixing seat 4 and the rubber pad can be engaged by interference fit, or other engagement methods are possible. When the fixing seat 4 and the card member 5 are engaged, the bottom surface of the NFC card 3 abuts against the ball 12 at a predetermined height, and the locking member 15 on the elastic member 14 is hooked with the buckle 53, so that the position of the card member 5 is locked, and the spring 52 is in a contracted and force-storing state, such as Figure 3At this time, the NFC card 3 can be rotated freely by hand, and the ball 12 effectively reduces the friction generated during the rotation process, making the rotation of the NFC card 3 smooth and flexible.

[0034] When lubricating oil needs to be added to the ball 12, first press down the NFC card 3, driving the fixing seat 4 to move downward synchronously, and the ball 12 moves downward under the pressure from the NFC card 3, and the ball 12 will squeeze the elastic member 14, causing the elastic member 14 to deviate from its original position. At this time, the fastener 53 is no longer hooked by the elastic member 14, and the spring 52 begins to release the stored force and push the card 5 to move upward. At this time, the moving directions of the fixing seat 4 and the card 5 are opposite and staggered, so that the fixing seat 4 and the card 5 are disengaged, and the fixing seat 4 can be easily removed, making it convenient to replace or clean the ball bearing.

[0035] When reinstalling, the holder 4 with the NFC card 3 installed is inserted into the card sleeve 1. The holder 4 engages with the card member 5 and drives the fastener 53 downward. The NFC card 3 then contacts the ball 12, which drives the elastic member 14 to deflect. The fastener 53 then moves downward and is located below the locking member 15. The spring 52 begins to contract and accumulate force. When the user lets go, the elastic member 14 pushes the ball 12 upward, which pushes the NFC card 3 and the holder 4 upward. The locking member 15 deflects and returns to the position directly above the fastener 53. The holder 4 drives the engaged card member 5 upward. The spring 52 begins to release its potential energy, causing the fastener 53 to move upward and engage with the locking member 15, locking the card member 5 in place and thus locking the holder 4.

[0036] In the above technology, the NFC card 3 can be freely rotated by hand through the setting of the ball bearing, and the friction generated during the rotation is effectively reduced by the ball 12, so that the rotation of the NFC card 3 is smooth and flexible, which increases the fun of the use process. When the ball bearing needs to be replaced or cleaned, only the NFC card 3 needs to be pressed to disengage the fixing base 4 and the card 5, and the fixing base 4 can be easily removed.

[0037] As an embodiment further provided by the present invention, a plurality of elastic balls 42 are fixedly provided on the fixing seat 4, and a ball groove 51 adapted to the elastic balls 42 is opened on the clamping member 5;

[0038] The elastic ball 42 has two movable positions in the ball groove 51: a high position and a low position.

[0039] Specifically, during installation, the fixing seat 4 equipped with the NFC card 3 is inserted into the card sleeve 1. The NFC card 3 is pressed and the elastic support force of the elastic member 14 on the ball 12 is overcome. The fixing seat 4 drives the elastic ball 42 downward. The elastic ball 42 is first squeezed and deformed by the inner wall of the card sleeve 1 until it moves into the ball groove 51 and is released. Then, the NFC card 3 drives the fixing seat 4 to slide from a high position to a low position. When the NFC card 3 is pressed down again, the fixing seat 4 will press the card member 5 downward and drive the buckle 53 to be located under the locking member 15, and the spring 52 accumulates force. After releasing the card 3, the spring 52 pushes the card member 5 upward, and the NFC card 3 is pushed upward by the ball 12, and the elastic ball 42 slides from a low position to a high position and stops at the high position.

[0040] When the fixing base 4 needs to be removed, the NFC card 3 is pressed down in the same manner. The fixing base 4 drives the elastic ball 42 to move from the high position to the low position. Since the NFC card 3 presses the ball 12, the ball 12 drives the elastic member 14 to deflect and disengage from the locking member 15. At this time, the fastener 53 is no longer hooked by the elastic member 14, and the spring 52 begins to release the stored force and push the card 5 upward. At this time, the moving directions of the fixing base 4 and the card 5 are opposite and staggered, and the elastic ball 42 disengages from the ball groove 51, so that the fixing base 4 and the card 5 are disengaged.

[0041] As another embodiment further provided by the present invention, a card strip 41 for receiving the NFC card 3 is provided in the fixing seat 4 .

[0042] Specifically, the card strip 41 is made of a plastic material with a certain degree of elasticity, and a groove is formed along the edge of the NFC card 3. When assembling the NFC card 3, the card 3 is pressed downward to overcome the supporting force of the ball bearing 12 on the NFC card 3, and the card strip 41 is squeezed into the groove, and the elastic member 14 accumulates energy. Then, the elastic member 14 releases the stored energy and pushes the ball bearing 12, which pushes the NFC card 3 upward. At this time, the card strip 41 presses against the side wall of the groove, preventing the NFC card 3 from escaping. The contact area between the card strip 41 and the NFC card 3 is small, allowing the NFC card 3 to rotate flexibly.

[0043] As another embodiment further provided by the present invention, it also includes a transparent cover 2 that is plugged into the ferrule 1.

[0044] Specifically, the card holder 1 has a slot 11 formed in a trapezoidal shape, wide at the top and narrow at the bottom. When the transparent cover 2 is inserted, it moves along the wide side of the trapezoid toward the narrow side, ultimately being restrained by the narrow side. The transparent cover 2 protects the NFC card 3, preventing it from colliding with other objects when placed in a pocket. Furthermore, the thinness of the transparent cover 2 prevents interference with signal transmission from the NFC card 3.

[0045] As another embodiment further provided by the present invention, a spring 52 for pushing the clamping member 5 to extend upward is provided on the clamping sleeve 1, and there is a triggering station for ejecting the transparent cover 2 in the movable stroke of the clamping member 5.

[0046] Specifically, the card 5 is slidably arranged in the slot 11. An elastic convex surface 21 is fixedly provided at the center of the transparent cover 2, and the elastic convex surface 21 has a concave state for pressing the NFC card 3. When the transparent cover 2 needs to be removed, the elastic convex surface 21 is pressed down to the concave state, and the elastic convex surface 21 presses the NFC card 3 downward. At this time, the NFC card 3 pushes the elastic member 14 to bend through the ball 12, and the elastic member 14 drives the locking member 15 to deviate. The locking member 15 no longer blocks the buckle 53, so that the elasticity of the spring 52 is released and pushes the card 5 upward. When the card 5 moves upward, it reaches the trigger position, and the card 5 pushes the transparent cover 2, so that the transparent cover 2 is out of the slot 11.

[0047] Working principle: During installation, press down the NFC card 3 and overcome the supporting force of the ball 12 on the NFC card 3, squeezing the card strip 41 into the groove. Insert the fixed seat 4 equipped with the NFC card 3 into the card sleeve 1, press the NFC card 3 and overcome the elastic supporting force of the elastic member 14 on the ball 12. The fixed seat 4 drives the elastic ball 42 downward. The elastic ball 42 is first squeezed and deformed by the inner wall of the card sleeve 1 until it moves into the ball groove 51 and is released. Then, the NFC card 3 drives the fixed seat 4 to slide from the high position to the low position. When the NFC card 3 is pressed down again, the fixed seat 4 will press the card member 5 downward, and drive the fastener 53 to be located under the locking member 15, and the spring 52 accumulates force. After releasing the grip, the spring 52 pushes the card 5 upward, and the NFC card 3 is pushed upward by the ball 12. The elastic ball 42 slides from the low position to the high position and stops at the high position. At this time, the card strip 41 presses against the side wall of the groove to prevent the NFC card 3 from falling out. The contact area between the card strip 41 and the NFC card 3 is small, and the card strip 41 can rotate freely.

[0048] Then the transparent cover 2 is inserted, and the transparent cover 2 moves along the wide side of the trapezoid toward the narrow side, and is finally restricted by the narrow side.

[0049] When the transparent cover 2 needs to be removed, the elastic convex surface 21 is pressed downward to a concave state. The elastic convex surface 21 presses the NFC card 3 downward. At this time, the NFC card 3 pushes the elastic member 14 to bend through the ball 12. The elastic member 14 drives the locking member 15 to deflect. The locking member 15 no longer blocks the buckle 53, allowing the elasticity of the spring 52 to be released and push the card 5 upward. When the card 5 moves upward, it reaches the triggering position, pushing the transparent cover 2, causing the transparent cover 2 to eject from the slot 11. The fixing base 4 and the card 5 move in opposite directions and staggered. The elastic ball 42 disengages the ball groove 51, causing the fixing base 4 and the card 5 to be disengaged. The fixing base 4 can now be removed.

[0050] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
