Description

Special sinker for fishing gear

technical field

The utility model belongs to the field of aquaculture appliances, in particular to a special sinker for fishing gear.

Background technique

The sinker is one of the important accessories of the fishing gear and has sinking force. When the fishermen are working, they cooperate with the float to ensure the desired shape and position of the fishing gear in the water, or to increase the sinking speed of the fishing gear and the pressure of the lower edge of the fishing gear on the bottom of the water. . Usually, when fishermen use nets to fish, in order to make the nets sink into the water better, it is necessary to arrange a plurality of sinkers on the lower edge of the nets. And existing sinker uses the material with larger specific gravity to make more, as stone material, pottery, iron or forms with clay firing. At present, in order to further reduce costs, most sinkers are mainly fired from clay.

When the sinker is made of metal with a large specific gravity such as iron, it is easy to rust in water, and it will even be damaged after long-term use and lose its use value; when choosing a sinker fired with clay, due to its low strength And it is easy to absorb water, and the damage rate in use is extremely high. Fishermen need to change the sinker frequently to ensure the smooth progress of fishing work. In addition, due to the structural defects of the existing sinker, the connection strength between it and the net gear is not enough, and the sinker will easily fall off after long-term use.

In summary, it is particularly necessary to improve the existing sinker.

Practical new content

Technical problem to be solved: the purpose of this utility model is to overcome the deficiencies of the prior art and provide a special sinker for fishing gear. The sinker has a large specific gravity and strong corrosion resistance, and can make the net gear It is better fixed on it, so as to ensure that the sinker is not easy to fall off.

The new technical scheme of the utility model:

The special sinker for fishing gear includes a sinker body and a through hole. The center of the sinker body is provided with a through hole. The groove is coated with a metal core between the polytetrafluoroethylene inner layer and the polytetrafluoroethylene outer layer, and the grooves are arranged at both ends of the sinker body.

In the special sinker for fishing gear, the body of the sinker is in the shape of a shuttle.

The special sinker for fishing gear, wherein, the outer surface of the sinker body is provided with a hook.

In the special sinker for fishing gear, at least two grooves are symmetrically arranged at both ends of the sinker body.

In the special sinker for fishing tackle, the hook is in the shape of a mouth, one end of which is integrally formed with the outer layer of polytetrafluoroethylene, and an opening is formed between the other end and the outer layer of polytetrafluoroethylene.

Beneficial effect

The utility model uses the inner layer of polytetrafluoroethylene and the outer layer of polytetrafluoroethylene to coat the metal core, so that the sinker has a larger specific gravity and stronger corrosion resistance, and the grooves at both ends of the sinker body can make the net The tool is better fixed on the sinker, even if it is used for a long time, it will not easily cause the sinker to fall off from the net; setting hooks on the outer layer of polytetrafluoroethylene can further enhance the fixing performance of the net and sinker.
