[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0036] The following is for reference. Figures 1-7 Description of the anklet 100 according to an embodiment of the present utility model.

[0037] like Figures 1-7 As shown, the ankle ring 100 according to an embodiment of the present invention includes: a first half-ring 10, a second half-ring 20, and a locking fastener 30. The two ends of the first half-ring 10 are a first connecting end 12 and a first open end 11, respectively; the two ends of the second half-ring 20 are a second connecting end 22 and a second open end 21, respectively. The first connecting end 12 of the first half-ring 10 and the second connecting end 22 of the second half-ring 20 are rotatably connected; the locking fastener 30 is configured such that when the first half-ring 10 and the second half-ring 20 are closed, the first open end 11 and the second open end 21 are fixedly connected by the locking fastener 30.

[0038] In this embodiment, the ankle ring 100 is provided with a first half-ring 10 and a second half-ring 20. The first connecting end 12 of the first half-ring 10 and the second connecting end 22 of the second half-ring 20 are rotatably connected. For example, the first connecting end 12 and the second connecting end 22 can rotate relative to each other about a rotation axis, and the rotation axis can be relative to the axial direction of the ankle ring 100 (e.g., the first connecting end 12 and the second connecting end 22). Figure 1 (The directions shown are up and down) are in the same direction. When the first half-ring 10 and the second half-ring 20 are closed, the locking device 30 fixes the first open end 11 and the second open end 21 of the first half-ring 10, thereby making the first half-ring 10 and the second half-ring 20 cooperate to form a stable ring structure.

[0039] When the operator attaches the leg band 100 to the bird's leg, the leg band 100 can be in an open state, that is, the first open end 11 of the first half-ring 10 is away from the second open end 21 of the second half-ring 20. The operator can move the bird's leg from the opening formed between the first open end 11 and the second open end 21 to the radially inner side of the first half-ring 10 and the second half-ring 20. The operator then rotates the first half-ring 10 and the second half-ring 20 to close them, so that the leg band 100 can be placed on the bird's leg. The operator then uses the locking fastener 30 to fix the first half-ring 10 and the second half-ring 20 to the first open end 11 and the second open end 21, so that the leg band 100 can be securely attached to the bird's leg, thus completing the operation of attaching the leg band 100 to the bird.

[0040] In this embodiment, by setting a rotatably connected first half-ring 10 and second half-ring 20, the leg band 100 can be easily and conveniently fitted onto the bird's leg. The locking fastener 30 fixes the first half-ring 10 and the second half-ring 20 together to complete the installation and fixation of the leg band 100 on the bird's leg. This ensures that the leg band 100 will not cause damage to the bird during installation. The operator only needs to rotate the first half-ring 10 and the second half-ring 20 and use the locking fastener 30 to fix the first half-ring 10 and the second half-ring 20 together to install the leg band 100. The operation is convenient and easy, and there is no need to consider the risk of damaging the bird's leg. This makes the installation of the leg band 100 easier and allows a single operator to complete the installation operation, thereby reducing the labor cost of installing the leg band 100.

[0041] According to the embodiment of the present invention, the leg band 100 is provided with a first half-ring 10 and a second half-ring 20. The first connecting end 12 of the first half-ring 10 and the second connecting end 22 of the second half-ring 20 are rotatably connected. When the first half-ring 10 and the second half-ring 20 are closed, the first open end 11 of the first half-ring 10 and the second open end 21 of the second half-ring 20 are fixedly connected by a locking fastener 30. The structure is simple, which makes it easy to install the leg band 100 on the legs of birds, making the installation of the leg band 100 easier and reducing labor costs.

[0042] In some embodiments of this utility model, such as Figure 2 As shown, one of the first open end 11 and the second open end 21 may be provided with a slot 211 and the other may be provided with a plug 111. When the first half ring 10 and the second half ring 20 are closed, the first half ring 10 and the second half ring 20 are connected to the plug 111 through the slot 211.

[0043] In this embodiment, one of the first opening end 11 and the second opening end 21 is provided with a slot 211 and the other is provided with a plug 111. For example, the first opening end 11 may be provided with a slot 211, and the second opening end 21 may be provided with a plug 111, or the first opening end 11 may be provided with a plug 111, and the second opening end 21 may be provided with a slot 211.

[0044] When the first half-ring 10 and the second half-ring 20 are closed, they are connected to the insert block 111 via the slot 211. For example, after the first half-ring 10 and the second half-ring 20 are closed, the insert block 111 can abut against the inner wall of the slot 211. For instance, in the circumferential direction of the foot ring 100, the end face of the insert block 111 can abut against the side wall of the slot 211. In this embodiment, the first half-ring 10 and the second half-ring 20 are connected to the insert block 111 via the slot 211. The structure is simple and can provide a certain guiding and limiting effect on the closing of the first half-ring 10 and the second half-ring 20. After the insert block 111 extends into the slot 211, the first half-ring 10 and the second half-ring 20 can rotate around the rotation axis in a plane perpendicular to the axial direction of the foot ring 100, thereby allowing the first half-ring 10 and the second half-ring 20 to stably cooperate to form a closed ring structure.

[0045] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the first opening end 11 may be provided with a plug 111, and the second opening end 21 is provided with a slot 211. On the axial direction of the foot ring 100, the plug 111 forms a first fixing hole 101, and a second fixing hole 201 is formed on one side wall of the slot 211. The second fixing hole 201 penetrates the second opening end 21, and the locking fastener 30 passes through the second fixing hole 201 and extends into the first fixing hole 101. The locking fastener 30 is interference-fitted with the inner wall of the second fixing hole 201.

[0046] In this embodiment, the first open end 11 is provided with a plug 111, and the second open end 21 is provided with a slot 211. For example, the plug 111 protrudes away from the end plate of the first open end 11 along the extension direction of the first half ring 10, and the slot 211 is recessed away from the end plate of the second open end 21 along the extension direction of the second half ring 20. When the first half ring 10 and the second half ring 20 are closed, the end face of the first opening end can abut against the end face of the second open end 21.

[0047] In this embodiment, a first fixing hole 101 is formed on the insert block 111, and a second fixing hole 201 is formed on one side wall of the foot ring 100 along the axial direction, penetrating the second opening end 21 on that side. After the first half ring 10 and the second half ring 20 are closed in place, the second fixing hole 201 and the first fixing hole 101 are arranged opposite each other in the axial direction of the foot ring 100. The locking fastener 30 can be inserted into the second fixing hole 201 and continue to extend into the first fixing hole 101 along the axial direction of the foot ring 100, thereby connecting and fixing the first half ring 10 and the second half ring 20. The locking fastener 30 is interference-fitted with the inner wall of the second fixing hole 201, which is simple in structure and firmly fixed. The first half ring 10 and the second half ring 20 can be connected and fixed by inserting the locking fastener 30, which is convenient and quick to operate.

[0048] In some examples of this utility model, such as Figure 2 As shown, the insert 111 may include a locking section 1111 and a guide section 1112 extending and connected along the extension direction of the first semi-ring 10. The locking section 1111 is provided with a first fixing hole 101. The guide section 1112 is provided on the side of the locking section 1111 opposite to the first connecting end 12. In the extension direction of the first semi-ring 10, the thickness of the guide section 1112 in the axial direction of the foot ring 100 gradually decreases away from the locking fastener 30.

[0049] In this embodiment, the insert 111 has a locking section 1111 and a guide section 1112 formed in the extension direction of the first half-ring 10. The locking section 1111 is provided with a first fixing hole 101. The thickness of the guide section 1112 in the axial direction of the leg ring 100 gradually decreases away from the locking fastener 30. The guide section 1112 can play a good guiding role in the insertion connection between the insert 111 and the slot 211, so that the insert 111 can be inserted into the slot 211 more easily and conveniently. This makes it easier and faster to close the first half-ring 10 and the second half-ring 20 when they are installed on the bird's leg, thereby improving the installation efficiency of the leg ring 100 to a certain extent.

[0050] In one example of this utility model, reference is made to Figure 2 and Figure 3 As shown, the guide segment 1112 can be formed as a guide slope on one side surface of the foot ring 100 in the axial direction. In the axial direction of the foot ring 100, the guide slope extends obliquely away from the locking segment 1111 and toward the other side surface of the guide segment 1112 in the extension direction of the first half ring 10. This satisfies the setting requirements of the guide segment 1112 and makes the processing of the guide segment 1112 more convenient.

[0051] In some examples of this utility model, references Figure 2 and Figure 3As shown, the first fixing hole 101 can be a blind hole. The first fixing hole 101 is a blind hole. For example, when the locking fastener 30 is fixedly connected to the first half-ring 10 and the second half-ring 20, the locking fastener 30 and the second fixing hole 201 can be arranged on the same side of the first fixing hole 101 along the axial direction of the foot ring 100. This allows the insert block 111 and the slot 211 to have smaller opening structures, thereby giving the first half-ring 10 and the second half-ring 20 better structural strength at the position of the locking fastener 30. This improves the overall structural stability and reliability of the first half-ring 10 and the second half-ring 20 after they are closed and fixed, thus reducing the probability of the first half-ring 10 and the second half-ring 20 opening during long-term use, making the use of the foot ring 100 more stable and reliable.

[0052] In some embodiments of this utility model, such as Figures 5-7 As shown, the locking fastener 30 may include: a housing 31, a fixing pin 33, and an elastic element 32. The housing 31 extends axially along the foot ring 100 and has a receiving cavity 311 open at one end; the fixing pin 33 extends axially along the foot ring 100 and one end extends into the receiving cavity 311, the fixing pin 33 is engaged with the housing 31, and the fixing pin 33 is movable relative to the housing 31 along the axial direction of the foot ring 100; the elastic element 32 is deformable along the axial direction of the foot ring 100, the elastic element 32 is disposed in the receiving cavity 311, and both ends of the elastic element 32 are respectively connected to the bottom wall of the receiving cavity 311 and the fixing pin 33.

[0053] In this embodiment, the locking fastener 30 includes a housing 31, a fixing pin 33, and an elastic element 32. The elastic element 32 is disposed in the receiving cavity 311 of the housing 31, and its two ends are respectively connected to the bottom wall of the receiving cavity 311 and the fixing pin 33. One end of the fixing pin 33 extends into the receiving cavity 311 and is movable relative to the housing 31 along the axial direction of the foot ring 100. When the locking fastener 30 fixes the first half ring 10 and the second half ring 20, the locking fastener 30 is inserted into the second fixing hole 201, and the fixing pin 33 can extend into the first fixing hole 101. The locking fastener 30 can be press-fitted with the inner wall of the second fixing hole 201 through the housing 31, and the fixing pin 33 is inserted into the first fixing hole 101 to connect and fix the first half ring 10. When the first fixing hole 101 is a blind hole, the fixing pin 33 can stably engage with the bottom wall of the first fixing hole 101 under the elastic deformation of the elastic element 32, thereby making the connection and fixation between the fixing pin 33 and the first fixing hole 101 more stable and reliable. Optionally, the elastic element 32 is a spring.

[0054] In some embodiments of this utility model, such as Figure 1 As shown, the first connecting end 12 and the second connecting end 22 can be hinged together.

[0055] In this embodiment, the first connecting end 12 and the second connecting end 22 are hinged together, which has a simple structure, is convenient and stable to connect, and can well meet the connection needs of the first half ring 10 and the second half ring 20.

[0057] In this embodiment, the first connecting end 12 is provided with a first hinge seat 121, and the second connecting end 22 is provided with a second hinge seat 221. The first hinge seat 121 extends into the mating groove 2212 of the second hinge seat 221. The pivot pin 40 passes through the first through hole 1211 of the first hinge seat 121 and the second through hole 2211 of the second hinge seat 221 along the axial direction of the foot ring 100. The axis of the pivot pin 40 can be formed as the rotation axis of the first half ring 10 and the second half ring 20, and the first half ring 10 and the second half ring 20 can rotate relative to each other around the axis of the pivot pin 40. In this embodiment, the first connecting end 12 and the second connecting end 22 are respectively provided with a first hinge seat 121 and a second hinge seat 221, and the pivot pin 40 passes through the first through hole 1211 and the second through hole 2211. The structure is simple, facilitates the assembly of the first half ring 10 and the second half ring 20, and can well meet the usage needs of the foot ring 100.

[0058] In some embodiments of this utility model, both the first half-ring 10 and the second half-ring 20 can be made of aluminum alloy.

[0059] In this embodiment, the first half-ring 10 and the second half-ring 20 are made of aluminum alloy. Aluminum alloy has the characteristics of being lightweight, corrosion-resistant, easy to process, and having good durability. In this embodiment, making the first half-ring 10 and the second half-ring 20 of aluminum alloy makes the leg band 100 lighter and more beautiful, and has good corrosion resistance and durability. It effectively avoids the impact on the normal activities of birds due to the weight of the leg band 100 after it is installed, so that the leg band 100 can be better applied to birds. It also makes the overall structural strength of the leg band 100 better, and it is not easy to deform or rust. This greatly increases the service life of the leg band 100 and extends its service cycle. This can reduce the frequency of replacing and maintaining the leg band 100 to a certain extent, and thus greatly reduce the cost of bird tracking and research.

[0060] In some embodiments of this utility model, the outer surfaces of both the first half-ring 10 and the second half-ring 20 may have a wear-resistant layer.

[0061] In this embodiment, the outer surfaces of the first half-ring 10 and the second half-ring 20 have a wear-resistant layer, which can further extend the service life of the ankle ring 100 and further improve the service life of the ankle ring 100.

[0062] In some embodiments of this utility model, reference is made to Figure 1 and Figure 4 As shown, one of the first half-ring 10 and the second half-ring 20 may have a groove 23 on the side wall surface of the foot ring 100 on the radially outer side, and the groove 23 extends circumferentially along the foot ring 100.

[0063] In this embodiment, a groove 23 is provided on the side wall of one of the first half-ring 10 and the second half-ring 20. For example, a groove 23 can be provided on the first half-ring 10 or the second half-ring 20. The groove 23 extends circumferentially along the ankle ring 100. The structure is simple. The groove 23 can serve as an installation and positioning structure so that identification tags, chips, trackers, etc. installed on the ankle ring 100 can be embedded in the ankle ring 100 without affecting the comfort and safety of wearing. Alternatively, it can be used to engrave identification information such as numbers, letters, or QR codes, thereby enhancing the expansion space of the ankle ring 100 and making the ankle ring 100 more practical.

[0064] The following will refer to Figures 1-7 Description of an anklet 100 according to a specific embodiment of the present invention.

[0065] like Figures 1-7As shown, the ankle ring 100 includes a first half-ring 10, a second half-ring 20, a locking fastener 30, and a pivot pin 40. The first half-ring 10 and the second half-ring 20 are made of aluminum alloy and have a wear-resistant layer on their outer surfaces. The two ends of the first half-ring 10 are a first open end 11 and a first connecting end 12, respectively. The first open end 11 is provided with a plug 111, and the plug 111 is provided with a first fixing hole 101. The first connecting end 12 is provided with a first hinge seat 121, and the first hinge seat 121 is provided with a first through hole 1211, which is a blind hole. The second half-ring 20... The two ends are a second open end 21 and a second connecting end 22, respectively. The second open end 21 forms a slot 211. The slot 211 has a second fixing hole 201 on one side wall of the foot ring 100 in the axial direction. The second fixing hole 201 passes through the second open end 21 on this side. The second connecting end 22 is provided with a second hinge seat 221. The second hinge seat 221 is provided with a second through hole 2211. The first hinge seat 121 is inserted into the mating groove 2212 of the second hinge seat 221. The pivot pin 40 passes through the first through hole 1211 and the second through hole 2211.

[0066] When the leg band 100 is installed on the bird's leg, the leg band 100 is in the open state. The operator snaps the leg band 100 onto the bird's leg from one side and closes the first half ring 10 and the second half ring 20, so that the insert block 111 is inserted into the slot 211 and inserted into place. The first fixing hole 101 communicates with the second fixing hole 201. The locking fastener 30 is inserted into the second fixing hole 201 and extends into the first fixing hole 101, thus completing the installation of the leg band 100.

[0067] In this embodiment, by setting a rotatably connected first half-ring 10 and second half-ring 20, the leg band 100 can be easily and conveniently fitted onto the bird's leg. The locking fastener 30 fixes the first half-ring 10 and the second half-ring 20 together to complete the installation and fixation of the leg band 100 on the bird's leg.
