Description

Technical Field

[0001] This utility model relates to an animal ear tag, specifically an animal ear tag with detachable main tag legs and reusable main tag. Background Technology

[0002] Animal ear tags are tools used to identify and manage animals, and are widely used in animal husbandry, pet management, and laboratory animal research. RFID electronic animal ear tags use radio frequency identification technology to enable long-distance reading, making them suitable for smart farms.

[0003] There are many types of animal ear tags on the market, mainly focusing on improvements in function and size, aiming to achieve wider functionality and a smaller size. For example, the applicant's prior patent 201822026579.5 discloses a quick-penetration, graded positioning, wound-exposed multifunctional animal ear tag, which uses three quick-penetration, graded positioning pins to fix the main tag and the secondary tag to the animal's ear, resulting in a relatively large size. Therefore, the applicant has developed a double-pin wound-exposed multifunctional animal ear tag, namely the prior utility model patent 202121049708.8, which reduces the number of quick-penetration, graded positioning pins from three to two, improves the layout of the device, adds a hollow design, reduces the weight of the ear tag, and adds a sleeve made of highly inert, smooth plastic material around the quick-penetration, graded positioning pins, thereby reducing damage to the animal's skin. However, most existing animal ear tags are single-use. This is because the quick-release positioning pin of these ear tags connects to the main tag on the main tag itself. Therefore, removing the ear tag will damage the main tag, resulting in the ear tag being completely discarded and not recyclable, thus causing waste. Therefore, if the main tag of the ear tag could be recycled and its initial parameters reset, it could be reused, which would reduce costs and prevent excessive plastic waste from being generated from discarded ear tags.

[0004] Therefore, an animal ear tag with reusable and detachable main tag legs has become a goal pursued by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to solve the problem that when the main and secondary tags of existing animal ear tags are separated, the main tag cannot be reused because the ear stud is inserted into the main tag, which leads to increased costs and excessive electronic plastic waste that pollutes the environment.

[0006] To achieve the above objectives, the present invention employs the following technical solution: an animal ear tag with detachable main tag legs, comprising a main tag assembly, a secondary tag assembly, and two quick-penetration grading positioning pins for connecting the main tag assembly and the secondary tag assembly. The main tag assembly includes an upper main tag shell and a lower main tag shell, and further includes a leg assembly. The leg assembly includes two columnar legs and a connector connecting the two legs. The lower end of each leg has a through hole for the quick-penetration grading positioning pins to pass through. The inner cavity of each leg is provided with a... The clamp for receiving and clamping the quick-penetration grading positioning needle has a plug at the upper end of the leg for sealing the clamp; the outer surface of the main label lower shell has a protrusion in the shape of an arc cylinder, and on both sides of the protrusion are bosses for mounting the leg, and the bosses have a second through hole for the quick-penetration grading positioning needle to pass through; the connector is arc-shaped to fit the protrusion of the main label lower shell; the quick-penetration grading positioning needle passes through the second through hole and the first through hole and is non-detachably connected and fixed to the clamp.

[0007] As a preferred embodiment, an animal ear tag with a detachable main tag leg has a groove on the outer surface of the protrusion for the connector to be inserted. The connector is an arc-shaped strip that matches the shape of the groove, and the connector and the groove are in an interference fit.

[0008] As a preferred embodiment, an animal ear tag with a detachable main tag leg has two protruding ribs on the upper surface of the protrusion, and the groove is formed between the two protruding ribs; the upper arc of the connector has protruding reinforcing ribs on both sides.

[0009] As a preferred embodiment, an animal ear tag with a detachable main tag leg includes a clamping member comprising an upper clamping member in the shape of a cylindrical sleeve and a lower clamping member in the shape of a conical sleeve, as well as an inwardly protruding stop at the lower end; the inner diameter of the stop is smaller than the diameter of the annular protrusion on the quick-penetration grading positioning needle, and is adapted to the diameter of the recess between two adjacent annular protrusions on the quick-penetration grading positioning needle; and the clamping member has a longitudinally formed groove; the inner cavity of the leg is adapted to the outer contour of the clamping member, including a cylindrical hole at the upper part and a conical hole at the lower part.

[0010] As a preferred embodiment, an animal ear tag with a detachable main tag leg has a tapered chamfer at the lower part of the inner diameter of the stop portion.

[0011] As a preferred embodiment, an animal ear tag with a detachable main tag leg has two or more slots, preferably four.

[0012] As a preferred embodiment, an animal ear tag with a detachable main tag leg has a cavity one for accommodating a battery formed below the protrusion of the lower shell of the main tag, and a U-shaped convex ring is provided on the outer side of the protrusion, with a U-shaped cavity two inside the convex ring.

[0013] As a preferred embodiment, an animal ear tag with a detachable main tag leg has an upper main tag shell horizontally positioned at the end of the lower main tag shell to seal the first cavity and the second cavity.

[0014] As a preferred embodiment, an animal ear tag with a detachable main tag leg includes a secondary tag assembly comprising a sheet-shaped plastic pad made of TPU material, a receiving space under the plastic pad surrounded by an elliptical ring-shaped protrusion, and a metal pad made of metal material whose shape is adapted to the receiving space; the tail end of a quick-penetration grading positioning pin is connected to the metal pad and the plastic pad.

[0015] As a preferred embodiment, an animal ear tag with a detachable main tag leg has a plastic sleeve on the outside of the quick-penetration grading positioning needle. One end of the sleeve has a stop ring, and the stop ring and the nail head at the tail end of the quick-penetration grading positioning needle connect the metal pad and the plastic pad into one piece.

[0016] The animal ear tag of this utility model firstly adds a tube leg assembly, which is connected to the quick-penetration grading positioning needle, and realizes the connection between the main tag assembly and the sub-tag assembly. Specifically, the leg assembly is designed as two cylindrical legs and a connector connecting the legs. The lower end of each leg has a through hole for the quick-penetration grading positioning needle to pass through. Secondly, on both sides of the arc-shaped protrusion of the main label's lower shell, there are bosses for receiving the legs. Each boss has a through hole for the quick-penetration grading positioning needle to pass through. The connector is designed as an arc shape that fits the protrusion of the main label, or in other words, the connector is n-shaped. The two legs are connected to both sides of the connector to form an n-shaped leg assembly. This n-shaped leg assembly can straddle the bosses. Thirdly, by providing a clamp inside the leg for connecting to the front end of the quick-penetration grading positioning needle, the end of the quick-penetration grading positioning needle can be non-detachably connected to the clamp inside the leg by passing through the main label assembly. This achieves the purpose of fixing the main label assembly and the sub-label assembly together to the animal's ear. Because the quick-release grading positioning pin is non-detachably connected to the leg assembly's clamps, while the main tag assembly is separate from the leg assembly, the main tag assembly is not damaged when removing the ear tag from the animal's ear. Therefore, the information within the main tag can be updated and reused. This is particularly suitable for animal ear tags used in animal husbandry management, as it can reduce costs and significantly decrease the electronic plastic waste generated by discarded ear tags, thus benefiting environmental protection.

[0017] The detachable main tag leg of the animal ear tag of this utility model is further improved by designing a groove on the surface of the protruding part of the lower shell of the main tag, and designing the shape of the connecting piece of the leg component to be an arc-shaped strip that fits the groove and is embedded in the groove, so that the leg component and the main tag component will not move together; furthermore, the fit between the two is designed to be an interference fit, so that the connecting piece can be embedded in the groove of the lower shell of the main tag and is not easy to fall off.

[0018] Furthermore, in the detachable main tag leg animal ear tag of this utility model, the groove on the outer surface of the main tag lower shell is formed by two raised ribs, which helps to reduce the thickness of the main tag lower shell and reduce the overall weight; the two sides of the arc-shaped strip connector are designed with reinforcing ribs, so that the main body of the connector is designed to be thinner. The reinforcing ribs ensure strength while minimizing weight.

[0019] Furthermore, the detachable main tag leg animal ear tag of this utility model has a clamping part designed as a cylindrical upper clamping part, a conical lower clamping part, and a stop part located at the bottom. A narrow groove is opened on the wall from bottom to top. The inner diameter of the stop part is smaller than the diameter of the annular protrusion on the quick-penetration grading positioning needle and is adapted to the diameter of the recess between two adjacent annular protrusions. Therefore, when the quick-penetration grading positioning needle is inserted into the stop part of the clamping part under the action of external force, the quick-penetration grading positioning needle can pass through the stop part due to the effect of the groove, and a non-detachable fixed connection is achieved.

[0020] Furthermore, the detachable main tag leg of the animal ear tag of this utility model has a cavity 1 inside the protrusion on the outer surface of the lower shell of the main tag to accommodate the battery. A U-shaped protrusion ring is provided on the outside of a protrusion, and a U-shaped cavity 2 is inside the protrusion ring. The cavity 1 and cavity 2 are used to accommodate electrical components such as batteries and circuit boards. At the same time, the design of the U-shaped protrusion ring makes it easy for the operator to hold and has no sharp edges to avoid injury to the animal.

[0021] Furthermore, in the detachable main tag leg animal ear tag of this utility model, the secondary tag component is designed as a sheet-like plastic pad and an oval-shaped metal pad. The metal pad is located below the plastic pad, and below the plastic pad is an oval ring-shaped protrusion. This oval ring-shaped protrusion forms a receiving space for the metal pad, so that the metal pad is embedded in the space. The plastic pad contacts the animal's ear, protecting the metal pad from injuring the animal's ear.

[0022] Furthermore, the detachable main tag leg of the animal ear tag of this utility model has a plastic sleeve at the nail head of the end of the grading positioning needle. The lower end of the sleeve has a stop ring. The stop ring and the nail head at the end of the grading positioning needle limit the metal pad and the plastic pad and are connected as one.

[0023] In summary, the animal ear tag of this invention has a more reasonable structure, which prevents damage to the main tag component when removing the ear tag, thus allowing the main tag component to be reused. This reduces breeding and management costs and minimizes environmental pollution. Attached Figure Description

[0036] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but these preferred embodiments should not be used to limit the scope of protection of the present invention.

[0037] It should be noted that, in order to clearly demonstrate the technical solution of this utility model, the terms "upper" and "lower" used in this utility model are based on... Figure 2 The location of each component is located in Figure 2 The upper direction is defined as "up", and the opposite direction is "down".

[0038] See Figure 1-13The figure shows the detachable main tag leg animal ear tag of this utility model, which includes a main tag assembly 1, a secondary tag assembly 2, and a quick-penetration grading positioning pin 3. The quick-penetration grading positioning pin 3 is used to fix the main tag assembly 1 and the secondary tag assembly 2 located on both sides of the animal's ear together. The utility model is characterized by further including a leg assembly 4, which has two columnar legs 41 and a connector 42 connecting the two legs 41. The legs 4 are preferably cylindrical. The lower end of the legs 41 has a through hole 411 for the quick-penetration grading positioning pin 3 to pass through. A clamp 43 is provided in the inner cavity of the legs 41 for receiving and clamping the quick-penetration grading positioning pin 3. The upper end of the legs 41 has a plug 44 for sealing the clamp 43. The clamp 43 is assembled. Inside the cavity of the leg 41, the main label assembly 1 includes a lower main label shell 11 and an upper main label shell 12, which are connected as one unit. The outer surface of the lower main label shell 11 has a protrusion 111 in the shape of an arc-shaped cylindrical surface. On both sides of the protrusion 111, there are bosses 112 for mounting the leg 41. The bosses 112 have through holes 113 for quick-penetration grading positioning pins 3 to pass through. The connector 42 is arc-shaped to fit the protrusion 111 of the lower main label shell 11. Thus, the outer contour of the leg assembly 4 forms an n-shape. The quick-penetration grading positioning pin 3 passes through the through hole 113 on the boss 112 of the main label assembly 1 and the through hole 411 at the lower end of the leg 41, and is non-detachably connected and fixed to the clamp 43. Because this utility model adds a tube leg assembly 4, and the quick-penetration grading positioning needle 3 passes through the sub-label assembly 2, the main label assembly 1 and the tube leg assembly 4 in a non-detachable fixed connection, when removing the ear tag, cutting the quick-penetration grading positioning needle 3 will not damage the main label assembly 1, which can be recycled and reused. When reused, only its information needs to be updated. This reduces waste in ear tags for breeding management, lowers animal breeding management costs, reduces the generation of electronic plastic waste, and prevents environmental pollution.

[0039] In this invention, the detachable main tag leg of the animal ear tag further enhances the relative position between the main tag assembly 1 and the leg assembly 4. Ideally, the upper surface of the protrusion 111 of the lower main tag shell 11 has an annular groove 114. The connector 42 is an arc-shaped strip adapted to the shape of the groove 114, and the width of the connector 42 is interference-fitted with the width of the groove 114. The connector 42 is embedded in the annular groove 114, making the two integral. The position of the leg 41 of the leg assembly 4 is fixed, facilitating the insertion of the quick-connect grading positioning needle 3. The interference fit prevents the two from separating.

[0040] In the detachable main tag leg animal ear tag of this utility model, preferably, the upper surface of the protrusion 111 has two protruding ribs 118, and a groove 114 is formed between the two protruding ribs 118. The connector 42 is precisely embedded in the groove 114 between the two ribs 118. Obviously, the groove 114 can also be formed by directly recessing downward on the upper surface of the protrusion 111. Compared with the solution where the two ribs 118 form a groove, the solution with two ribs 118 results in a smaller overall weight. Preferably, the arc-shaped upper surface of the connector 42 has protruding reinforcing ribs 421 on both sides, which can improve strength, or in other words, minimize weight while ensuring sufficient strength.

[0041] In a further preferred embodiment, the detachable main tag leg of the animal ear tag of this utility model includes an upper clamping part 431, a lower clamping part 432, and an inwardly protruding annular stop part 433 at the lower end. The upper clamping part 431 is cylindrical, and the lower clamping part 432 is conical. The inner diameter of the stop part 433 is smaller than the diameter of the annular protrusion 31 on the quick-penetration grading positioning needle 3 and is adapted to the diameter of the recess 32 between two adjacent annular protrusions 31 on the quick-penetration grading positioning needle 3. The clamping part 43 has longitudinally opened grooves 434, and the number of grooves 434 is two or more, preferably four. The inner cavity of the leg part 41 is adapted to the outer contour of the clamping part 43, including a cylindrical hole 412 at the upper part and a conical hole 413 at the lower part. Since the inner cavity of the leg 41 has a conical portion that is adapted to the lower part 432 of the clamp, the conical portion can generate an inward squeezing force, so that the clamp 43 has sufficient clamping force.

[0042] In this embodiment, there are four slots 434, which can be increased or decreased as needed. During use, the quick-connect grading positioning pin 3, under external force, enters the stop portion 433 at the lower part of the clamp 43. Due to the longitudinal slots 434, the stop portion 433 and the lower part 432 of the clamp 43 are stretched apart by the external force. The annular protrusion 31 on the quick-connect grading positioning pin 3 passes through the stop portion 433 and enters. The stop portion 433 of the clamp 43 automatically retracts and locks into the recess 32 on the quick-connect grading positioning pin 3, thereby completing the installation and fixation of the animal ear tag.

[0043] To facilitate the quick-passing grading positioning needle 3 passing through the stop part 433, it is best to have a tapered chamfer 435 at the lower part of the inner diameter of the stop part 433. By setting the chamfer 435, it is convenient to guide the quick-passing grading positioning needle 3 into the stop part 433.

[0044] The detachable main tag leg animal ear tag of this utility model includes a cavity 115 inside the protrusion 111 of the lower shell 11 of the main tag to accommodate a battery 6. A U-shaped horizontal ring 116 is provided on the outer side of one of the protruding parts 112, and the ring 116 contains a U-shaped cavity 117 for housing a Bluetooth antenna. A symmetrical protrusion support 119 of the same height as the protrusion 112 is provided on the outer side of another protrusion 112. To reduce weight, weight-reducing holes are provided on the protrusion support 119 around the protrusion 112.

[0045] See Figure 2 The upper main cover 12 is horizontally positioned at the lower end of the lower main cover 11, used to seal the first cavity 115 and the second cavity 117; a circuit board 5 is provided inside the cavity 115, such as... Figure 7 As shown, the structure of the main cover 12 is consistent with the structure of the prior patent, and will not be described again.

[0046] The detachable main tag leg of the animal ear tag of this utility model, in order to prevent the secondary tag that contacts the animal's ear from causing harm to the animal, includes a secondary tag assembly 2 comprising a sheet-shaped plastic pad 21 made of TPU material. Underneath the plastic pad 21 is a receiving space 211 surrounded by an elliptical ring-shaped protrusion 212. A metal pad 22 made of metal material with a shape adapted to the receiving space 211 is disposed in the receiving space 211. The plastic pad 21 is correspondingly provided with a hole 213 for the quick-penetration grading positioning needle 3 to pass through. The center of the metal pad 22 is partially occupied by a space 221 for accommodating a magnet 7. A Hall switch 8 is disposed in the center of the circuit board 5 corresponding to the magnet 7. The Hall switch 8 is used to sense the magnet 7. When the secondary tag assembly 2 is separated from the main tag assembly 1, the Hall switch 8 can no longer sense the magnet 7 and will issue an alarm message to monitor whether the ear tag has fallen off.

[0047] In the preferred embodiment of the detachable main tag leg animal ear tag of this utility model, the quick-penetration grading positioning needle 3 is externally provided with a plastic sleeve 33. One end of the sleeve 33 has a stop ring 331. The stop ring 331 and the nail head 34 at the tail end of the quick-penetration grading positioning needle 3 connect the metal pad 22 and the plastic pad 21 into one unit. The sleeve 33, which is made of plastic and comes into contact with the animal's ear, prevents the metal quick-penetration grading positioning needle 3 from damaging the animal's ear.

[0048] The above description is illustrative only and not restrictive. The present invention aims to provide an animal ear tag. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the claims. For example, the number of quick-release grading positioning pins, the number of slots on the clamp, etc., will all fall within the protection scope of the present invention.
