[0025] Reference Figure 1-Figure 2 According to an embodiment of the key chain of the utility model, it includes a large connecting buckle 11, a chain 12 and a key ring 13, the key ring 13 is provided with a notch 14, and the notch 14 is provided with a connecting seat 15 fixedly connected to the key ring 13, the connecting seat 15 is provided with a lifting groove 16 opening upward, and a sliding sleeve 17 is connected to the lifting groove 16 for sliding up and down, the side of the lifting groove 16 is provided with a through groove penetrating outward, and the side of the sliding sleeve 17 is provided with an arc plate 18 passing through the through groove and extending to the outside of the connecting seat 15, and the arc plate 18 can abut against the inner ring of the key ring 13 to close the notch 14.
[0026] The sliding sleeve 17 is connected to one end of the chain 12 via a connecting column 31 , and the other end of the chain 12 is connected to the large connecting buckle 11 , and also includes a positioning mechanism for controlling the upper and lower positions of the sliding sleeve 17 relative to the connecting seat 15 .
[0027] When the key needs to be clamped or removed, the user first uses the positioning mechanism to make the sliding sleeve 17 sink to the lowest side in the connecting seat 15. At this time, the gap 14 is no longer closed by the curved plate 18, and the user can place the key in the key ring 13 through the gap 14. Then, the user uses the positioning mechanism to lift the sliding sleeve 17 and the curved plate 18 until the curved plate 18 abuts against the inner curved surface of the key ring 13. At this time, the gap 14 is closed, that is, the key on the key ring 13 is difficult to fall out.
[0028] In this embodiment, the positioning mechanism includes a No. 1 spring 19 arranged on the bottom surface of the lifting groove 16, and the upper side of the No. 1 spring 19 is connected to the sliding sleeve 17. Under the action of the No. 1 spring 19, the sliding sleeve 17 tends to move upward and makes the arc plate 18 tend to stick to the key ring 13.
[0029] In addition, in order to facilitate the upper and lower locking positions of the sliding sleeve 17, so that the user does not need to press the sliding sleeve 17 and the arc plate 18 downward all the time to keep the notch 14 in an open state, an ejection slot 41 is provided in the sliding sleeve 17, and an ejection plate 42 is connected to the ejection slot 41 for sliding left and right, and a second spring 43 is connected between the ejection plate 42 and the side of the ejection slot 41, and a pressing plate 44 and a clamping plate 45 extending to the outside of the sliding sleeve 17 are provided on the left side of the ejection plate 42, and the pressing plate 45 is always on the upper side of the connecting seat 15, and a rubber pad is installed at the end of the pressing plate 44, so that the user can press it by hand;
[0030] A card slot 21 for accommodating the card plate 45 is disposed in a side surface of the lifting slot 16 . The card slot 21 is provided with two cards distributed up and down. The user can press the pressing plate 44 to move the card plate 45 and the pop-up plate 42 left and right.
[0031] When the card plate 45 moves to the left into the card slot 21 at the lower side, the positions of the pop-up plate 42, the sliding sleeve 17 and the arc plate 18 are locked, and the notch 14 is in an open state, which is convenient for the user to place the key on the key ring 13 through the notch 14.
[0032] When the key is taken out or placed, the user presses the pressure plate 44 inward so that the card plate 45 enters and leaves the card slot 21. Then the sliding sleeve 17 can move upward relative to the connecting seat 15 to allow the card plate 45 to enter the card slot 21 on the upper side. At this time, the arc plate 18 abuts against the key ring 13 and closes the gap 14.
[0033] When the arc plate 18 and the sliding sleeve 17 are at the uppermost side and the notch 14 is in a closed state, in order to prevent the clamping plate 45 from escaping from the clamping slot 21 located on the upper side and to ensure that the arc plate 18 is in a state of closing the notch 14, a groove is provided in the upper side surface of the clamping slot 21, and the end of the clamping plate 45 is bent upward so as to be able to enter the groove.
[0034] Operation process: the user first presses down the connecting column 31 and makes the card plate 45 abut against the lower side of the card slot 21. At this time, the card plate 45 is separated from the groove. Then the user presses the pressure plate 44 and makes the card plate 45 separate from the card slot 21. At this time, the sliding sleeve 17 and the arc plate 18 can move up and down.
[0035] In the second embodiment of the key chain, the large connecting buckle 11 includes a buckle body and a base plate 22, a mounting ring 23 is fixedly provided on the lower side of the base plate 22, and a small connecting buckle 24 is installed at the end of the chain 12 away from the connecting column 31. After the chain 12 passes through the mounting ring 23, the small connecting buckle 24 is connected to the chain 12 itself. The user can control the length of the chain 12 passing through the mounting ring 23 and the position of the small connecting buckle 24 buckled on the chain 12, thereby controlling the length of the key ring 13 and the key located in the key ring 13 from the large connecting buckle 11.
[0036] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
