Description

Technical Field

[0001] This utility model relates to the field of public transport card technology, specifically to a connection structure for a "golden cudgel" public transport card. Background Technology

[0002] A public transport card is an electronic payment card used for public transport payments. Currently, the most widely used type is the contactless public transport card (RFID card), which utilizes Radio Frequency Identification (RFID) technology. The card contains a chip and an induction coil. When the public transport card is brought close to a reader (usually a few centimeters), the radio frequency signal emitted by the reader induces a current in the card's induction coil, powering the chip inside the card. Simultaneously, data is transmitted between the chip and the reader via radio frequency signals. This method makes the card-swiping process very fast and convenient; passengers simply need to bring the card close to the reader to complete the payment. In recent years, with the rise of diverse aesthetic preferences, public transport cards have evolved from traditional rectangular cards into designs featuring animals, cultural relics, and other designs, which have become popular with the public.

[0003] When designing the Golden Cudgel-shaped bus card, a coil and chip are often set at one end and screwed or snapped onto the stick body through a shell. However, this fixing method is not reliable, and the separation of the shell and the stick body reduces the overall aesthetic appearance. Workers try to screw the cover inside the end of the stick body, but when the cover is tightened, part of the cover will still be exposed, resulting in poor overall aesthetics of the Golden Cudgel. Moreover, in long-term use, there are still cases where the stick body and the cover fall off. Utility Model Content

[0004] The purpose of this utility model is to provide a connection structure for a "golden cudgel" bus card to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A connecting structure for a "golden cudgel" public transport card includes a rod body with a placement cavity at one end. The placement cavity contains an induction coil and a chip. The structure also includes a cover body adapted to the placement cavity, with external threads on the outer side and internal threads corresponding to the external threads on the inner wall of the placement cavity; and a rotator slidably disposed within the cover body, with one end extending from the cover body. A locking device is also provided between the rotator and the cover body, restricting the rotator's movement relative to the cover body when the end of the rotator moves to be flush with the end of the cover body.

[0007] Furthermore, the rotator includes a sliding disc slidably connected to a sliding groove inside the cover body. One end of the sliding disc is fixedly connected to a rotating plate. The rotating plate is slidably connected to the end of the cover body and extends out of the cover body. A locking device is provided between the sliding disc and the cover body.

[0008] Furthermore, the locking device includes a limiting rod slidably connected to the sliding plate, a compression spring fixedly disposed between the limiting rod and the sliding plate, a first limiting groove is provided on the cover, the first limiting groove is adapted to the sliding rod, and when the end of the rotator moves to be flush with the end of the cover, the limiting rod extends into the first limiting groove.

[0009] Furthermore, the rod body is provided with a second limiting groove that is adapted to the limiting rod. The second limiting groove is connected to the placement cavity. When the cover is screwed into the placement cavity, the second limiting groove is connected to the first limiting groove.

[0010] Furthermore, an elastic arc-shaped protrusion is fixedly provided on the side wall of the sliding disk, and a groove adapted to the protrusion is provided on the inner wall of the cover. When the protrusion is located in the groove, the sliding disk is at the end of the sliding groove away from the rod.

[0011] Furthermore, there are multiple protrusions, and the grooves are arranged in a one-to-one correspondence with the protrusions.

[0012] In the above technical solution, the connecting structure of the Golden Cudgel bus card provided by this utility model has the following beneficial effects:

[0013] The rotating mechanism drives the cover to rotate, causing the external thread on the cover to engage with the internal thread on the placement cavity, allowing the cover to fully extend into the placement cavity. Pressing the rotating mechanism causes it to slide. When the rotating mechanism moves to be flush with the end of the cover, the locking device restricts its movement to prevent it from extending out of the cover. At this point, the ends of the rod, the cover, and the rotating mechanism are all in the same plane, making the rod more aesthetically pleasing. Furthermore, since the cover does not protrude from the rod, it is less likely to detach from the rod, thus improving the stability of the connection.

[0014] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Please see Figure 1-3 A connecting structure for a "golden cudgel"-shaped public transport card includes a rod body 1, one end of which has a placement cavity 11 containing an induction coil and a chip. It also includes a cover 2, which is fitted to the placement cavity 11, with external threads on its outer side and internal threads corresponding to the external threads on the inner wall of the placement cavity 11; and a rotator 3, which is slidably disposed within the cover 2, with one end extending out of the cover 2. A locking device 4 is also provided between the rotator 3 and the cover 2, restricting the movement of the rotator 3 relative to the cover 2 when the end of the rotator 3 moves to be flush with the end of the cover 2. The rod body 1 is shaped like a golden cudgel.

[0024] Rotating the rotator 3 causes the cover 2 to rotate, and the rotation of the cover 2 causes the external thread on the cover 2 to engage with the internal thread on the placement cavity 11, so that the cover 2 is fully inserted into the placement cavity 11. Pressing the rotator 3 causes the rotator 3 to slide. When the rotator 3 moves to be flush with the end of the cover 2, the locking device 4 restricts the movement of the rotator 3 to prevent the rotator 3 from extending out of the cover 2. At this time, the end of the rod 1, the end of the cover 2 and the end of the rotator 3 are in the same plane, making the rod 1 more aesthetically pleasing. Since the cover 2 is not exposed from the rod 1, it is not easy to fall off the rod 1, thus improving the stability of the connection.

[0025] Furthermore, the rotator 3 includes a sliding disc 31 slidably connected to a sliding groove inside the cover 2. One end of the sliding disc 31 is fixedly connected to a rotating plate 32. The rotating plate 32 is slidably connected to the end of the cover 2 and extends out of the cover 2. A locking device 4 is provided between the sliding disc 31 and the cover 2.

[0026] Furthermore, the locking device 4 includes a limiting rod 41 slidably connected to the sliding plate 31, a compression spring 42 fixedly disposed between the limiting rod 41 and the sliding plate 31, and a first limiting groove 43 is provided on the cover 2. The first limiting groove 43 is adapted to the sliding rod. When the end of the rotating device 3 moves to be flush with the end of the cover 2, the limiting rod 41 extends into the first limiting groove 43.

[0027] When the end of the rotator 3 moves to be flush with the end of the cover 2, the compression spring 42 drives the limiting rod 41 to move, so that the limiting rod 41 extends into the first limiting groove 43, thereby fixing the position of the sliding plate 31, so that the rotating plate 32 remains flush with the end of the cover 2 and does not protrude from the cover 2, thereby improving the overall aesthetics and the firmness of the connection.

[0028] Furthermore, the rod body 1 is provided with a second limiting groove 44 that is adapted to the limiting rod 41. The second limiting groove 44 is connected to the placement cavity 11. When the cover body 2 is screwed into the placement cavity 11, the second limiting groove 44 is connected to the first limiting groove 43.

[0029] When the cover 2 is screwed into the placement cavity 11, the limiting rod 41 extends into the first limiting groove 43 and the second limiting groove 44 in sequence under the action of the compression spring 42, thereby restricting the rotation of the cover 2 and the rod 1 and preventing the cover 2 and the rod 1 from falling off.

[0030] Furthermore, an elastic arc-shaped protrusion 51 is fixedly provided on the side wall of the sliding disk 31, and a groove 52 adapted to the protrusion 51 is provided on the inner wall of the cover 2. When the protrusion 51 is located in the groove 52, the sliding disk 31 is at the end of the sliding groove away from the rod 1. There are multiple protrusions 51, and the grooves 52 are arranged in a one-to-one correspondence with the protrusions 51.

[0031] When the sliding disk 31 is at the end of the sliding groove away from the rod 1, the rotating plate 32 extends out of the cover 2 so that the outside can drive the cover 2 to rotate through the rotating plate 32. The cooperation between the protrusion 51 and the groove 52 ensures that the sliding disk 31 will not slide due to a small external force, thus affecting the efficiency of the rotating plate 32 in driving the cover 2 to rotate.

[0032] Working principle: During installation, align the cover 2 with the placement cavity 11, first make the protrusion 51 on the sliding plate 31 engage with the groove 52, the rotating block extends out of the cover 2, rotate the rotating block to drive the cover 2 to move until the cover 2 is completely tightened into the placement cavity 11, press the rotator 3, when the end of the rotator 3 moves to be flush with the end of the cover 2, the compression spring 42 drives the limiting rod 41 to move, so that the limiting rod 41 extends into the first limiting groove 43 and the second limiting groove 44, thereby locking the cover 2 and the rotator 3 as well as the cover 2 and the rod 1.

[0033] 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.
