Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0033] like Figures 1-2 As shown, this utility model provides a mobile phone case, including a mobile phone case 1 and a detachable card 2 attached to the back of the mobile phone case 1. Both sides of the card 2 have patterns. Multiple cards 2 can be provided, and each card 2 can have different patterns printed on both sides. By replacing the cards 2, users can change the patterns or stickers on the back according to their personal preferences, allowing the phone's appearance to be changed at any time, increasing the fun and personalization of use.
[0034] Specifically, the back of the phone case 1 has a slot 3 for inserting a card 2, which is inserted into the slot 3. The slot 3 is open at the bottom and sealed at the top, and the card 2 is inserted into the slot 3 from bottom to top.
[0035] Furthermore, to prevent the card 2 from falling out of the slot 3 during use, a limiting mechanism 4 is provided on the bottom side of the slot 3 to restrict the bottom of the card 2.
[0036] Specifically, such as Figures 3-4As shown, the limiting mechanism 4 includes a mounting cavity 5, a slider 6, a ejector pin 7, a pressure rod 8, a spring 9, and a limiting rod 10. The ejector pin 7 and the pressure rod 8 are respectively located on both sides of the slider 6 and are positioned opposite each other. The mounting cavity 5 is rectangular, and the slider 6 is slidably disposed within the mounting cavity 5 and slides along the length of the mounting cavity 5. The ejector pin 7 and the pressure rod 8 slide out from the side walls at both ends of the mounting cavity 5. The spring 9 is located within the mounting cavity 5 and is sleeved on the ejector pin 7. The two ends of the spring 9 are distributed and abut against the side wall of the slider 6 and the inner wall of the mounting cavity 5.
[0037] The slider 6 has a limiting groove 11 on one side surface. One end of the limiting rod 10 is rotatably connected to the mounting cavity 5 by a pin, and the other end of the limiting rod 10 has a protrusion 12 that is perpendicular to the limiting rod 10. The protrusion 12 is located in the limiting groove 11 and slides along the limiting groove 11. The connection end of the limiting rod 10 and the mounting cavity 5 is located near the ejector pin 7.
[0038] The bottom side of slot 3 has a mounting hole, and mounting cavity 5 is fixedly installed inside the mounting hole. The pressure rod 8 is positioned facing outwards from slot 3. A pressure plate 19 is installed on the end of the pressure rod 8 outside slot 3. The pressure plate 19 is perpendicular to the pressure rod 8, allowing the user to press the pressure rod 8 and push the slider 6 to slide, thereby extending the ejector pin 7 to press against the bottom end of card 2, thus limiting the card 2's position. A telescopic sleeve 20 is provided between the pressure plate 19 and the outer wall of mounting cavity 5 to prevent dust accumulation after installation.
[0039] Specifically, such as Figure 5 As shown, the limiting groove 11 has a closed-loop structure, including a first groove 13, a second groove 14, a third groove 15, a fourth groove 16, a fifth groove 17, and a sixth groove 18 connected in sequence. The connection between the first groove 13 and the sixth groove 18, and the connection between the third groove 15 and the fourth groove 16, both protrude towards the side closer to the spring 9 for restriction. The connection between the first groove 13 and the second groove 14, and the connection between the fifth groove 17 and the sixth groove 18, protrude towards both sides of the mounting cavity 5.
[0040] The connection points of the first groove 13 and the sixth groove 18 and the connection points of the third groove 15 and the fourth groove 16 are respectively located on opposite sides of the central axis. This allows the protrusion 12 to move unidirectionally and cyclically within the limiting groove 11 during the pressing of the pressure rod 8.
[0041] By engaging the protrusion 12 on the limiting rod 10 with the limiting groove 11, after the user presses the pressure plate 19 for the first time, the slider 6 is pushed to slide, and the limiting rod 10 restricts the slider 6, thereby causing the ejector pin 7 to extend and press against the bottom end of the card 2 to limit the card 2; after the pressure plate 19 is pressed for the second time, under the elastic force of the spring 9, the limiting rod 10 releases the restriction on the slider 6, the slider 6 slides back to reset, and the ejector pin 7 retracts into the mounting cavity 5, so that the user can pull the card 2 out of the slot 3 for replacement.
[0042] In summary, the phone case provided by this utility model offers a variety of styles and patterns to choose from by changing the card on the back, allowing users to change the pattern or sticker on the back according to their personal preferences, so that the appearance of the phone can be changed at any time, increasing the fun and personalization of use.
[0043] Finally, it should be noted that the technical features of the technical solution of this application can be combined arbitrarily. In order to simplify the description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.
[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
