Description

Technical Field

[0001] This utility model belongs to the field of IC chip card technology, and specifically relates to a waterproof sealing structure for IC chip cards. Background Technology

[0002] With the widespread application of IC chip cards in financial payments, identity recognition, public transportation and other fields, their usage scenarios are gradually extending from indoors to outdoors, humid environments (such as using transportation cards in rainy weather, access cards in bathroom scenarios) or high-vibration scenarios (such as IC cards in industrial equipment operation). The waterproof performance and structural stability of chip cards have become key factors affecting their service life and functional security.

[0003] Currently, most traditional IC chip cards on the market are of an exposed design, relying solely on the card's own plastic casing for simple protection, lacking a dedicated waterproof sealing structure. When the chip card accidentally comes into contact with water, sweat, or is in a high-humidity environment, moisture can easily seep into the connection between the chip and the circuitry, causing short circuits, data loss, or malfunction. This is especially problematic for financial IC cards and ID card chip cards that store important information; damage to these cards can lead to financial losses or security risks to the user's identity information. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof sealing structure for IC chip cards, which can effectively seal IC chip cards and prevent sweat or moisture from seeping in and affecting the normal use of IC chip cards.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A waterproof sealing structure for an IC chip card includes a housing and a cover plate. Multiple plug-in components are provided between the cover plate and the housing. An annular groove is provided on the top end face of the housing. An annular sealing gasket is fixedly connected to the top end face of the housing at the annular groove. A tightening component is provided inside the annular sealing gasket. An elastic support component is provided in the inner cavity of the housing. The plug-in assembly includes multiple plug rods fixedly connected to the bottom surface of the cover plate near the edge. Multiple insertion holes are opened on the top end face of the box body. The plug rods are plugged into the insertion holes. A rubber sleeve is fixedly connected to the side wall of the plug rod.

[0007] The clamping assembly includes a cavity formed inside the housing below the insertion hole, the cavity communicating with the insertion hole. A top rod is fixedly connected to the bottom end of the insertion rod. A movable plate is movably connected to the side wall of the cavity. The top rod is located above the right side of the movable plate. A telescopic rod is movably connected to the top surface of the cavity above the left side of the movable plate. The bottom end of the telescopic rod abuts against the upper surface of the left end of the movable plate. The top end of the telescopic rod extends to the inside of the annular sealing gasket and is fixedly connected to an annular arc block. The top of the annular arc block abuts against the annular sealing gasket.

[0008] Furthermore, a rotating shaft is rotatably connected to the sidewall of the cavity, and an elongated hole is formed near the center of the sidewall of the movable plate. The rotating shaft is located within the elongated hole, and the movable plate and the sidewall of the cavity are rotatably connected via the rotating shaft. Furthermore, the elastic support assembly includes a placement plate disposed within the inner cavity of the box. Slider blocks are fixedly connected to the left and right sidewalls of the placement plate, and sliding grooves are formed on the left and right inner walls of the box. The sliders are slidably connected to the sliding grooves, and a spring is fixedly connected between the bottom surface of the sliding groove and the slider.

[0009] Furthermore, the bottom surface of the cover plate is fixedly connected with multiple protrusions.

[0010] Furthermore, hanging rings are fixedly connected to the right side walls of the box body and the cover plate, respectively.

[0011] The technical effects achieved by this utility model are as follows: The waterproof sealing structure of the IC chip card of this utility model achieves rapid insertion and installation through the cooperation between the plug-in component, the annular sealing gasket and the tightening component. The plug-in component can achieve a highly stable connection by means of friction between the rubber sleeve and the insertion hole. At the same time, the tightening component can lift the annular sealing gasket and make it stick tightly to the end of the cover plate to achieve the purpose of waterproof sealing.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0019] like Figures 1-4 As shown, a waterproof sealing structure for an IC chip card includes a housing 1 and a cover plate 2. Both the bottom of the housing 1 and the cover plate 2 are made of acrylic material, providing good visibility for easy viewing of the printed content on the IC chip card. Multiple insertion components are provided between the cover plate 2 and the housing 1. An annular groove 12 is formed on the top end face of the housing 1, and an annular sealing gasket 6 is fixedly connected to the top end face of the housing 1 at the annular groove 12. A tightening component is provided inside the annular sealing gasket 6, and an elastic support component is provided inside the cavity of the housing 1.

[0020] like Figure 4 As shown, the plug-in assembly includes multiple plug rods 3 fixedly connected to the bottom surface of the cover plate 2 near the edge. Multiple insertion holes 4 are provided on the top end face of the housing 1. The plug rods 3 are plugged into the insertion holes 4, and rubber sleeves 5 are fixedly connected to the side walls of the plug rods 3. In this plug-in assembly, the interference fit of the plug-in type, combined with the friction between the rubber sleeves 5 and the insertion holes 4, achieves convenient and stable installation, allowing the cover plate 2 to be assembled without any other operations.

[0021] like Figure 2 and Figure 4 As shown, the clamping assembly includes a cavity 7 located inside the housing 1 below the insertion hole 4, which communicates with the insertion hole 4. A top rod 8 is fixedly connected to the bottom end of the insertion rod 3. A movable plate 9 is movably connected to the side wall of the cavity 7. The top rod 8 is located above the right side of the movable plate 9. A telescopic rod 10 is movably connected to the top surface of the cavity 7 above the left side of the movable plate 9. The bottom end of the telescopic rod 10 abuts against the upper left surface of the movable plate 9. The top end of the telescopic rod 10 extends to the inside of the annular sealing gasket 6 and is fixedly connected to an annular arc-shaped block 11. The top of the annular arc-shaped block 11 abuts against the annular sealing gasket 6. During insertion, the movable plate 9, using a lever principle, is linked with the insertion rod 3, which can lift the annular sealing gasket 6, increasing the adhesion between the annular sealing gasket 6 and the end face of the cover plate 2. In daily use, moisture and sweat cannot penetrate into the interior of the housing 1, thus achieving a waterproof seal and high practicality.

[0022] like Figure 4As shown, a rotating shaft 13 is rotatably connected to the side wall of cavity 7. An elongated hole is provided near the center of the side wall of movable plate 9, and the rotating shaft 13 is located inside the elongated hole. The movable plate 9 and the side wall of cavity 7 are rotatably connected by the rotating shaft 13. The cooperation between the rotating shaft 13 and the elongated hole can avoid the problem of uneven or incomplete contact between the movable plate 9 and the telescopic rod 10 when the movable plate 9 makes arc-shaped movements, and hides the components inside the box 1 without affecting the overall aesthetics.

[0023] like Figure 2 and Figure 3 As shown, the elastic support assembly includes a placement plate 14 disposed in the inner cavity of the box body 1. Slider 15s are fixedly connected to the left and right side walls of the placement plate 14 respectively. Slide grooves 16 are respectively opened on the left and right inner walls of the box body 1. The slider 15 is slidably connected to the slide grooves 16. A spring 17 is fixedly connected between the bottom surface of the slide grooves 16 and the slider 15.

[0024] By setting up an elastic support component, it can accommodate IC chip cards of different thicknesses or quantities. On the other hand, the force of spring 17 can buffer and protect the IC chip cards when the box 1 falls, keeping the IC chip cards in the correct position.

[0025] like Figure 3 As shown, multiple protrusions 18 are fixedly connected to the bottom surface of the cover plate 2. The protrusions 18 are used to press against the IC chip card, reduce the contact area with the IC chip card, and avoid scratches or abrasions.

[0026] like Figure 1 As shown, hanging rings 19 are fixedly connected to the right side walls of the box body 1 and the cover plate 2 respectively. The two hanging rings 19 form an arc-shaped hanging ring with a circular cross-section, which makes it convenient for users to hang the IC chip on the key ring through the hanging rings 19.

[0027] The working principle of this utility model is as follows: First, the IC chip card is placed on the placement plate 14 inside the box 1. Then, the cover plate 2 is inserted into the insertion hole 4 through the insertion rod 3 and the cover plate 2 is pressed down. The friction between the rubber sleeve 5 and the insertion hole 4 is used to fix the cover plate 2. At the same time, the protrusion 18 presses against the IC chip card and squeezes it. The force of the spring 17 can limit and protect the IC chip card, so that it is tightly attached to the inside of the box 1. When the insertion rod 3 is pressed down, the insertion rod 3 drives the top rod 8 to press down on one side of the movable plate 9. The movable plate 9 is lifted by the lever action generated by the rotating shaft 13 and pushes the telescopic rod 10 to rise. The telescopic rod 10 drives the annular arc block 11 to rise and pushes the annular sealing gasket 6 to fit against the end of the cover plate 2 to achieve efficient sealing.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
