Abstract
The invention relates to a counterweight for fishing gear of making the fish hook or fishing net sink into the water, and the purpose of the invention is to provide this counterweight for fishing gear, which can prevent being hooked in the water, thereby avoiding economic loss, and even losing in the water also avoiding polluting water. The counterweight of the invention includes a body with a throughhole; a coating layer covering the body outer surface and the throughhole inner surface; and an elastic protrusion radial formed wholly on the coating outer surface.
Description
Technical field
The present invention relates to a kind of fishing gear counterweight that is used to make fish hook and fishing net submerged, the surfaces externally and internally that relates in particular to a kind of its body applies an elastomeric material and in the whole counterweight that forms a plurality of elastic protrusions of this this external surface.
Background technology
Usually, counterweight can be divided into: little counterweight of using on the fishhook that links to each other with setline and the big counterweight that is used for fishing net and links to each other with the lower end of this fishing net, and these counterweight major parts all make by the lead material with larger specific gravity, to make it not to be subjected to the influence of buoyancy.
As shown in Figure 6, above-mentioned counterweight comprises that one has the integral body 1 of oval cross section and the through hole of a center line formation longitudinally, and described through hole makes and is easy to the silk thread connection.
When counterweight that handle links to each other with setline drops in the water, usually can when backguy, can therefore pull apart because of its little surface area is colluded between rocklet or gravel pebbles.
Particularly, in those places of basement rock for example, a lot of obstacles is arranged, a lot of fishes are usually also arranged, the easier quilt of counterweight catches on also easier losing, and simultaneously, other fishing gears that link to each other with these counterweights also can be lost.
In addition, when above-mentioned counterweight linked to each other with fishing net, counterweight was colluded between rock or gravel pebbles, fishing net was torn or the counterweight frequent loss.
If counterweight is lost, then have economic loss, and it is pretty troublesome to reconnect a new counterweight.And the counterweight that is made by lead can make water be polluted, thereby destroys ground water regime.
Summary of the invention
In order to solve the above problems, one object of the present invention is to provide a kind of fishing gear counterweight, and it can prevent to be hooked in water, thereby avoids economic loss, and, if it is lost, can not cause that water pollutes yet.
For achieving the above object, the invention provides a kind of fishing gear counterweight, it comprises: a body that has through hole; One is used to cover the coating of the outer surface and the through-hole inner surface of described body; With on the outer surface of described coating radially and integrally formed a plurality of elastic protrusion.
Preferably, described body is made by the bigger metal of proportion.
Above-described counterweight of the present invention is used as fish hook counterweight or fishing net counterweight, and the elastic protrusion with predetermined length, this make when its by water in rock or gravel pebbles be not torn when catching on, and, even lose, can not pollute because of raw-material coat does not cause water yet.
Description of drawings
The features and advantages of the present invention will be clearer in the description to its preferred embodiment below in conjunction with accompanying drawing, wherein:
Fig. 1 is the perspective view of fishing gear of the present invention with counterweight;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3-Fig. 5 is the usage schematic diagram of fishing gear of the present invention with counterweight;
Fig. 6 is the perspective view that the fishing gear in the prior art is used counterweight.
Embodiment
Describe first and second embodiment of the present invention now in detail, described embodiment is shown in the drawings.When description is of the present invention, will represents identical parts with identical title and Reference numeral, and omit identical description.
Fig. 1 is the perspective view of fishing gear of the present invention with counterweight; Fig. 2 is the sectional view of Fig. 1.
In this embodiment of the present invention, counterweight comprises a body 1 that has through hole 2, and this similar to the prior art.But among the present invention, the whole surfaces externally and internally of body 1 all scribbles raw rubber, and radially is formed with a plurality of elastic protrusions 3 of predetermined length on described outer surface.
Body 1 is made by powdery or granular metal or the caking of metallic alloy, and it has very big proportion.Especially, described body 1 be can't help heavy metal lead and is made.
When counterweight falls into the water and during disbonding, this will have been avoided owing to the serious water that uses for example plumbous heavy metal to cause pollutes.
The coating 3 that is made by raw rubber covers the outer surface of bodies 1 and the whole surface of through hole 2, forms the surfaces externally and internally of body 1 by injection mo(u)lding, makes body 1 be sealed fully and exposed.
The ellipse that the cross section of counterweight is preferably similar to prior art, and on the outer surface of the coating 3 that makes by raw rubber, integrally radially form a plurality of elastic protrusions 4.
Described elastic protrusion 4 has predetermined length, as shown in Figure 1, preferably respectively has three projections to be positioned at the upper and lower of counterweight, and four projections are positioned at the middle part.And the characteristic of described elastic protrusion 4 can support the weight of counterweight and can not be out of shape, and just can make its bending when it applies external force.
When fishing gear of the present invention is used for setline with counterweight, as shown in Figure 3,, flexible projection 4 is not easy to be colluded between rocklet owing to making this counterweight.When this counterweight is passed big gap between rock, as shown in Figure 4, when drawing setline, counterweight will be fled from therebetween owing to the deformation of projection 4.
In addition, as shown in Figure 5, when fishing gear of the present invention was used for fishing net with counterweight, counterweight can not caught on by the gravel pebbles at the bottom, and this makes net not be torn, and counterweight can not lost.
Simultaneously, described counterweight can be made by other materials that can not produce the water pollution, and coating also can be made by having identical flexible synthetic resin with raw rubber.
Advantage of the present invention is summarized as follows:
As mentioned above, even fishing gear of the present invention is not easy to be colluded between rock with counterweight and is caught on also and can therefrom flee from, this has reduced the quantity of losing counterweight, also reduces economic loss simultaneously.In addition, if counterweight is lost, be coated with coating on also can body and avoid because the water that heavy metal and oxidation are caused pollutes because of this counterweight.
Although the front has been described several embodiment especially,, the present invention can have multiple other embodiments obviously, and they are all within the spirit and scope of the present invention.Therefore, embodiments of the invention only are illustrative, and can in the protection domain of claim the present invention be made amendment and replace.
Claims (2)
