Abstract

The utility model designs a plastic eel cage which is a special tool for capturing finless eels by fisherman. The utility model comprises a main barrel, main ears, a tail barrel, a tail ear, and a barrel cap. Both ends of the cylinder-shaped main barrel are respectively provided with a cone-shaped main ear, and the cone-shaped tail ear is positioned at the connecting part of the cylinder-shaped tail barrel and the main barrel; the lower part of the tail barrel is provided with the barrel cap; all components are respectively provided with a small hole. The utility model has the advantages of low cost, high capturing rate, long service life, convenient operation, without influencing by environment and weather, light weight, etc.

Description

Plastic eel cage

The utility model belongs to marine industry, and specifically a kind of fisherman is used for catching the specific purpose tool of swamp eel---plastic eel cage.

Traditional eel cage is to use reed stems, bamboo chip is manual works out, backward in technique, cost of manufacture height (existing market price is about 5 yuan), productivity ratio is extremely low, also there are many shortcomings in actual the use, as rough surface, permeability and poor flexibility, the swamp eel difficulty is advanced easily to escape, the immersion back is perishable, and easily go rotten, general life cycle is no more than 1 year, and thin bamboo strip system eel cage mounted is torn comparatively inconvenience open, it need often ted, otherwise will go rotten its overcast and rainy can't use, and thin bamboo strip system eel cage water imbibition extra-heavy, time is long more in water, weight is heavy more, and every of average is between 800 grams-1000 grams, and carrying to the fisherman makes troubles.

The purpose of this utility model then is the problem at above-mentioned existence, has designed a kind of employing PS plastics (GPPS) or waste or used plastics, and injection mo(u)lding on injection machine is convenient to automatic forming processing, the plastic eel cage of producing in enormous quantities.

The utility model technical solution:

A kind of plastic eel cage of forming by positive tube, positive fringe, tail pipe, tail fringe, tube cap, it is characterized in that cylinder shape just is equipped with the positive fringe of pyramid type in tube two ends, pyramid type tail fringe places cylinder shape tail pipe and positive tube junction, and the tail pipe bottom has a cap, and wherein above-mentioned each parts all have aperture.

The utility model compared with prior art has following advantage:

1, cost is low: plastic eel cage can be produced in enormous quantities, has improved production efficiency greatly, has reduced cost simultaneously, and according to accounting, every cost of plastic eel cage is no more than 2 yuan, and selling price is no more than 4 yuan;

2, gather around and catch the rate height: plastic eel cage by the injection machine injection molded, has smooth surface through mould, and permeability is good, utilize the favorable elasticity of plastics, have the advantage that swamp eel easily advances to be unable to escape, according to measuring and calculating, every plastic eel cage than 5 kilograms of swamp eels of the annual fecund of thin bamboo strip system eel cage about;

3, service life is long: plastic eel cage adopts the desiccating plastic injection molded, has certain mechanical strength, and stable chemical performance, and is water-fast fully, and life cycle at least three years the longlyest reaches 5 years, and wherein damage of components can be changed;

4, easy to use, be not subjected to environment, climatic effect, improved productivity ratio, reduced fisherman's labour intensity: be threaded and emboss pit cooperation location because plastic eel cage has adopted, feasible mounting or dismounting are very simple, convenient, connect reliably simultaneously, can use equally overcast and rainy, need not ted, alleviate fisherman's working strength greatly;

5, in light weight: plastic eel cage does not have water imbibition, can soak for a long time in water, and weight can not increase, and general every product weight is between 300 grams-400 grams.

Fig. 1 is the utility model structural representation.

Fig. 2 is the positive fringe part-structure of a utility model schematic diagram.

Below in conjunction with accompanying drawing the utility model is further described:

In positive tube 2, put into the swamp eel bait, when swamp eel during, because along the elasticity of plastics itself, bore becomes greatly positive fringe 1 afterbody along with the entering of health of swamp eel through positive fringe 1 part, so that swamp eel enters positive tube 2 smoothly, positive then fringe 1 afterbody recovers normal caliber size.When swamp eel is wanted to run away, owing to against the elasticity of plastics, give resistance of swamp eel, add the wedge angle of positive fringe 1 afterbody, make the swamp eel fear bitterly, thereby can't run away from import department, have to enter tail pipe 4 parts, when laying positive tube 2 parts be put into water, tail pipe 4 surfaces, so that ventilative when final swamp eel enters tail pipe 4 parts, as tail pipe 4 is immersed in the water, swamp eel will be suffocated and be died.

Positive tube 2 parts are critical pieces of plastic eel cage, are cylinder shape, the long 600mm of stack shell, and the nozzle diameter is 82mm, has many apertures on the stack shell, with weight reduction, saves material.

Tail pipe 4 parts also are ventilation tube, and are cylindrical, and tube length 400mm, nozzle diameter are 72mm, after swamp eel enters positive tube 2,, will suffocate and die as the untimely tail pipe 4 that changes over to, afterbody 4 plays the effect that allows swamp eel breathe, and needs to offer aperture on stack shell and tail pipe cap 5, to increase airing function.

Positive fringe 1 part is conical, and spike length 125mm, inlet diameter are 85mm, and the tail end diameter is 12mm, and it is the office that secretly sets of plastic eel cage, and the outer ring is big, and the lining is young, utilizes the lastics of plastics again, makes swamp eel easily advance to be unable to escape.

Positive fringe 1 barrel branch has aperture, is conical and distributes, and afterbody 25mm does not have through hole, cuts when the pressing mold tool, is conical, divides ten to halve, to guarantee better elastic and certain mechanical strength.

It is conical that tail fringe 3 parts are, and spike length 110mm, inlet diameter are 73mm, and tail diameter is 12mm, and function and structure are identical with positive fringe part.

Tube cap 5 parts, the long 35mm of cap, diameter are 76mm, and it is the back switch of plastic eel cage, and take out the swamp eel that captures from here every day.

During design, positive tube 2 and positive fringe 1, tail pipe 4 and tail fringe 3, tail pipe 4 is to utilize the distinctive elasticity of plastics with being connected of cap 5 of tube, locatees with groove.Simple and reliable, convenient disassembly.

Positive tube 2 parts and tail pipe 4 parts adopt and are threaded.

Claims

1, a kind of plastic eel cage of forming by positive tube, positive fringe, tail pipe, tail fringe, tube cap, it is characterized in that cylinder shape just is equipped with the positive fringe of pyramid type in tube two ends, pyramid type tail fringe places cylinder shape tail pipe and positive tube junction, and the tail pipe bottom has a cap, and wherein above-mentioned each parts all have aperture.

2, plastic eel cage according to claim 1 is characterized in that the aperture that positive fringe barrel branch has is conical distribution, and afterbody 25mm does not have through hole, cuts when the pressing mold tool, is conical, divides ten to halve.
