Abstract

本实用新型公开了一种渔网网坠,其包括铁质的坠体,所述坠体为上小下大的形状,在坠体的上部设有贯穿坠体的通孔,在坠体外表面以及通孔内表面设有一层保护膜。所述通孔为两个,竖向排列,位于下方的通孔的孔径大于位于上方的通孔的孔径。该实用新型结构简单、合理,铁质的坠体能够避免实用铅质带来的水质污染,同时通过穿绳的方式将该网坠固定在网边上,减少了以往采用沟槽的不便及挂放不稳等不足,另外,上小下大的形状,由于重力的作用能够使得坠体更加快速的落水,捕鱼时更加方便。
The utility model discloses a net sinker of a fishing net, which comprises an iron sinker body; the sinker body has a smaller upper part and a larger lower part, wherein through holes penetrating the sinker body are formed at the upper part of the sinker body, and a layer of protective film is arranged on the outer surface of the sinker body and the inner surfaces of the through holes respectively; and the number of the through holes is two, the two through holes are arranged vertically, and the apertures of the lower through holes are greater than those of the upper through holes. The net sinker has a simple and reasonable structure; the problem of water pollution due to the use of lead is avoided by adopting the iron sinker body; meanwhile, since the net sinker is fixed on the net side in a stringing manner, the defects of inconvenience and unstable hanging due to the groove adopted before are reduced; besides, the sinker body with the smaller upper part and the larger lower part can fall into water at a higher speed under the action of gravity, so that the net sinker is more convenient for fish catching.
