An adaptive chicken leg ring for encapsulating an RFID chip

By using an adaptive adjustment mechanism and the cooperation of a conical groove and an insertion block, the inner diameter of the chicken leg ring is automatically adjusted, which solves the problem that the existing chicken leg ring cannot adapt to the growth of chickens and improves the safety and adaptability of use.

AI Technical Summary

Technical Problem

Existing chicken leg bands cannot automatically adjust their inner diameter according to the growth of chickens, resulting in ill-fitting leg bands rubbing against the legs of chickens during their growth, increasing the risk of infection, and failing to adapt to individual differences in a timely manner when adjusting in batches.

Method used

An adaptive adjustment mechanism is adopted, including a connecting shell, a plastic annular belt and a deflection torsion spring. The inner diameter is automatically adjusted through the cooperation of a tapered groove and an insertion block. It has two adjustment modes and uses elastic rebound force to ensure a close fit to the chicken feet.

Benefits of technology

It achieves adaptive adjustment of the inner diameter of the chicken leg ring, avoiding abrasions to chickens, reducing the risk of infection, improving the stability and adaptability of use, and ensuring that the chicken leg ring always fits the chicken's foot.

Abstract

The application discloses a self-adaptive chicken foot ring for packaging RFID chips, and relates to the technical field of poultry breeding. The chicken foot ring comprises a detachable outer shell body which is locked through a connecting piece, and a self-adaptive adjusting mechanism which is used for following the change of the chicken foot to change synchronously so that the chicken foot ring is always attached to the chicken foot. The self-adaptive adjusting mechanism comprises a connecting shell body which is attached to the chicken foot and a plastic annular belt which is attached to the chicken foot. The chicken foot ring is actually divided into two adjustment modes during use. Firstly, the internal space is changed by using the first mode. When the first mode is adjusted to the last value, the second adjustment intervenes, so that the inner diameter can be further expanded, and the first mode is reset. Meanwhile, during the adjustment of the second mode, the elastic pull force of the first mode always plays a winding role on the second mode, so that the variable range of the chicken foot ring is large, and the chicken foot ring is always attached to the chicken foot, thereby effectively improving the actual use effect of the chicken foot ring.
