[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the technical solution in this application embodiment effectively solves the technical problems of existing buckles being difficult to use and cumbersome to operate. The overall idea is as follows:

[0025] To address the problems existing in the prior art, this utility model provides an inward-facing buckle, including a semi-circular fixed ring 1. One end of the semi-circular fixed ring 1 is provided with a hinge mechanism. The semi-circular fixed ring 1 is hinged to a semi-circular movable ring 4 through the hinge mechanism. An L-shaped hook 5 is fixedly connected to the end of the semi-circular movable ring 4 away from the hinge mechanism. A slot 6 is opened at the end of the semi-circular fixed ring 1 away from the hinge mechanism. The hinge mechanism includes a fixed seat 101, a first limiting shaft 2, and a movable seat 401.

[0026] The fixing base 101 is fixedly connected to the end of the semi-circular fixing ring 1 away from the slot 6.

[0027] There are two movable seats 401, and both movable seats 401 are fixedly connected to the end of the semicircular movable ring 4 away from the L-shaped hook 5.

[0028] The first limiting shaft 2 is fixedly connected to the fixed seat 101, which is located between the two movable seats 401. The two ends of the first limiting shaft 2 are rotatably connected to the two movable seats 401 respectively.

[0029] A hanging ring 3 is fixedly connected to the side of the semicircular fixed ring 1 away from the semicircular movable ring 4.

[0030] The L-shaped hook 5 is compatible with the slot 6.

[0031] Semicircular fixing ring 1: This is the fixing part of the buckle, used to cooperate with the semicircular movable ring 4 to fit around the bird leg or to hang keys, etc., while providing an installation base for other components such as fixing base 101, hanging ring 3, etc.

[0032] First limiting shaft 2: It is fixedly connected to the fixed seat 101, and its two ends are rotatably connected to the two movable seats 401 respectively, so that the semi-circular movable ring 4 can rotate around it, realizing the hinge function of the semi-circular fixed ring 1 and the semi-circular movable ring 4.

[0033] Hanging ring 3: It is fixedly connected to the side of the semicircular fixed ring 1 away from the semicircular movable ring 4, and is used to hang epidemic prevention labels, nameplates, etc.

[0034] Semicircular movable ring 4: It is hinged to the semicircular fixed ring 1 through a hinge mechanism, and can be rotated to open or close. It cooperates with the semicircular fixed ring 1 to hold bird legs or keys, etc. One end is fixedly connected to two movable seats 401, and the other end is fixedly connected to an L-shaped hook 5.

[0035] L-shaped hook 5: It is fixedly connected to the end of the semicircular movable ring 4 away from the hinge mechanism, and is adapted to the slot 6 to fix the relative position of the semicircular movable ring 4 and the semicircular fixed ring 1.

[0036] Slot 6: Located at the end of the semicircular fixing ring 1 away from the hinge mechanism, it is adapted to the L-shaped hook 5 and is used to engage the L-shaped hook 5 when installing the bird buckle to achieve the function of fixing the buckle.

[0037] Working principle:

[0038] The semicircular movable ring 4 of this application can rotate through two movable seats 401 in conjunction with the first limiting shaft 2. The semicircular movable ring 4 of this application is fixed by the L-shaped hook 5 engaging with the slot 6. When this application is installed on the bird leg, the L-shaped hook 5 can be pulled to separate it from the slot 6, and the semicircular movable ring 4 and the semicircular fixed ring 1 can be unfolded. Then, the semicircular fixed ring 1 and the semicircular movable ring 4 can be used to cover the bird leg, and the L-shaped hook 5 can be re-engaged with the slot 6 to complete the installation. The hanging ring 3 can be used to hang epidemic prevention labels or nameplates, etc. Compared with the existing bird buckles that use screw and nut structures for fixing, this application is obviously easier to use. Example

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problems of existing buckles being difficult to use and cumbersome to operate. The overall idea is as follows:

[0040] To address the problems existing in the prior art, this utility model provides an inward-facing buckle, including a semi-circular fixed ring 1, one end of which is fixedly connected to a first limiting shaft 2, a semi-circular movable ring 4 is hinged to the semi-circular fixed ring 1 through the first limiting shaft 2, an L-shaped hook 5 is rotatably connected to the end of the semi-circular movable ring 4 away from the first limiting shaft 2, a locking block 102 is fixedly connected to the end of the semi-circular fixed ring 1 away from the first limiting shaft 2, and a hanging ring 3 is provided in the middle section of the semi-circular fixed ring 1.

[0041] The L-shaped hook 5 is fixedly connected to a second limiting shaft 501 at one end near the semi-circular movable ring 4. Both ends of the second limiting shaft 501 are rotatably connected to the semi-circular movable ring 4.

[0042] The end of the L-shaped hook 5 away from the second limiting shaft 501 is engaged with the locking block 102.

[0043] Both ends of the hanging ring 3 are provided with through holes 301, and the through holes 301 at both ends of the hanging ring 3 are sleeved with the semi-circular fixing ring 1.

[0044] Through holes 301: are formed at both ends of the hanging ring 3, for the semi-circular fixing ring 1 to pass through, so as to realize the sleeve connection between the hanging ring 3 and the semi-circular fixing ring 1.

[0045] The second limiting shaft 501 is fixedly connected to one end of the L-shaped hook 5 near the semi-circular movable ring 4, and both ends are rotatably connected to the semi-circular movable ring 4, so that the L-shaped hook 5 can rotate around it, making it easy to engage or disengage with the locking block 102.

[0046] Working principle:

[0047] When used as a keychain, the L-shaped hook 5 can be separated from the locking block 102, allowing the semi-circular movable ring 4 and the semi-circular fixed ring 1 to unfold through the first limiting shaft 2. At this time, the hanging ring 3 can be removed and attached to a belt or other part of the waistband. Then, the semi-circular fixed ring 1 can be passed through the two through holes 301. Meanwhile, the unfolded semi-circular movable ring 4 can pass through the key's hanging hole. After the attachment is completed, the L-shaped hook 5 can be reattached to the locking block 102. Compared with the existing two-layer spiral keychain, this application is obviously more convenient to use.

[0048] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
