Abstract
Basis is practical newly relates to the special sinker of a kind of fishing gear, belongs to aquaculture apparatus field.The special sinker of this fishing gear comprises sinker body and through hole, described sinker body central establishes through hole, sinker body is followed successively by inner polytetrafluoroethyllayer layer, polytetrafluorethylene outer layer, metal-cored, groove from the inside to the outside, clad metal core between inner polytetrafluoroethyllayer layer and polytetrafluorethylene outer layer, groove is located at the two ends of sinker body.The special sinker of described fishing gear, wherein, described sinker body is fusiformis.This is practical newly utilizes inner polytetrafluoroethyllayer layer and polytetrafluorethylene outer layer clad metal core, sinker is made to have larger proportion and stronger corrosion resistance, the groove at its sinker body two ends can make netting gear better be fixed on sinker, even if use for a long time, sinker easily can not be caused to come off from netting gear; Grab is set at polytetrafluorethylene outer layer, the fixed performance of netting gear and sinker can be strengthened further.
Description
Technical field
Basis is practical newly belongs to aquaculture apparatus field, is specifically related to the special sinker of a kind of fishing gear.
Background technology
Sinker is one of important accessory of fishing gear, has settling capacity, and it is when fisherman carries out operation, coordinates float to ensure the shape that fishing gear is required in water and position, or the settling velocity of increase fishing gear and fishing gear lower edge are to the pressure at the bottom.Usually, fisherman, when using netting gear fishing, in order to make netting gear can better submerged, needs under netting gear along arranging multiple sinker.And the larger material of existing sinker many uses proportion is made, as building stones, pottery, iron or fire with clay forms.At present, in order to further reduced cost, most of sinker mainly clay is fired.
When sinker is made with the metal that the proportions such as iron are larger, it very easily gets rusty in water, even damages and lose use value after long-time use; When selecting the sinker fired with clay, because its intensity is too low and easily absorb water, breaking-up rate is in use high, and fisherman needs often to change sinker guarantee and carry out smoothly at fishing operations.In addition, due to the structural defect of existing sinker, make the bonding strength between itself and netting gear inadequate, Long-Time Service easily causes sinker to come off.
In sum, the particularly necessity that just seems is improved to existing sinker.
practical fresh content
the technical problem solved:this practical new object overcomes the deficiencies in the prior art and provides a kind of fishing gear special sinker, and this sinker has larger proportion, and has stronger corrosion resistance, and netting gear can be made better fixed thereon, thus ensure sinker difficult drop-off.
this practical new technical scheme:
The special sinker of fishing gear, comprise sinker body and through hole, described sinker body central establishes through hole, sinker body is followed successively by inner polytetrafluoroethyllayer layer, polytetrafluorethylene outer layer, metal-cored, groove from the inside to the outside, clad metal core between inner polytetrafluoroethyllayer layer and polytetrafluorethylene outer layer, groove is located at the two ends of sinker body.
The special sinker of described fishing gear, wherein, described sinker body is fusiformis.
The special sinker of described fishing gear, wherein, the outer surface of described sinker body arranges grab.
The special sinker of described fishing gear, wherein, the two ends of described sinker body are symmetrical arranged at least 2 grooves.
The special sinker of described fishing gear, wherein, described grab is square shape, its one end and polytetrafluorethylene outer layer one-body molded, form opening between the other end and polytetrafluorethylene outer layer.
beneficial effect
This is practical newly utilizes inner polytetrafluoroethyllayer layer and polytetrafluorethylene outer layer clad metal core, sinker is made to have larger proportion and stronger corrosion resistance, the groove at its sinker body two ends can make netting gear better be fixed on sinker, even if use for a long time, sinker easily can not be caused to come off from netting gear; Grab is set at polytetrafluorethylene outer layer, the fixed performance of netting gear and sinker can be strengthened further.
Accompanying drawing explanation
Fig. 1 is the cutaway view of this practical new sinker;
Fig. 2 is this practical new vertical view;
Wherein, 1 is inner polytetrafluoroethyllayer layer, and 2 is polytetrafluorethylene outer layer, and 3 is metal-cored, and 4 is groove, and 5 is grab, and 6 is through hole.
Embodiment
Newly be described in further detail originally practical below by specific embodiment, wherein this practical new described metal-cored metal for having larger specific gravity, as the metal such as iron, lead.
embodiment 1
The special sinker of fishing gear, comprise sinker body and through hole 6, described sinker body central establishes through hole 6, sinker body is followed successively by inner polytetrafluoroethyllayer layer 1, polytetrafluorethylene outer layer 2, metal-cored 3, groove 4 from the inside to the outside, clad metal core 3 between inner polytetrafluoroethyllayer layer 1 and polytetrafluorethylene outer layer 2, groove 4 is located at the two ends of sinker body, and described sinker body is fusiformis.
embodiment 2
As depicted in figs. 1 and 2, the special sinker of fishing gear, comprise sinker body and through hole 6, described sinker body central establishes through hole 6, sinker body is followed successively by inner polytetrafluoroethyllayer layer 1 from the inside to the outside, polytetrafluorethylene outer layer 2, metal-cored 3, groove 4, clad metal core 3 between inner polytetrafluoroethyllayer layer 1 and polytetrafluorethylene outer layer 2, groove 4 is located at the two ends of sinker body, described sinker body is fusiformis, the outer surface of described sinker body arranges grab 5, the two ends of described sinker body are symmetrical arranged at least 2 grooves 4, described grab 5 is in square shape, its one end and polytetrafluorethylene outer layer 2 one-body molded, opening is formed between the other end and polytetrafluorethylene outer layer 2.
embodiment 3
The special sinker of fishing gear, comprise sinker body and through hole 6, described sinker body central establishes through hole 6, sinker body is followed successively by inner polytetrafluoroethyllayer layer 1, polytetrafluorethylene outer layer 2, metal-cored 3, groove 4 from the inside to the outside, clad metal core 3 between inner polytetrafluoroethyllayer layer 1 and polytetrafluorethylene outer layer 2, groove 4 is located at the two ends of sinker body, and described sinker body is fusiformis, and the two ends of described sinker body are symmetrical arranged at least 2 grooves 4.
In use, sinker is connected to the lower edge of netting gear, along the through hole arranged through sinker center under netting gear, after knotting is fixing, the grab that can be arranged by outer surface is again fixed further, thus ensures that sinker is firmly fixed on netting gear.
