Abstract

The utility model relates to a folding crabbing cage, which comprises a pedestal, an upper cover and a netting which is laid on outsides of the pedestal and the upper cover, wherein two to four crab inlet holes are uniformly distributed on the circumference of the netting; a folding device is arranged between the center of the pedestal and the center of the upper cover; four to eight guy ropes are vertically and uniformly distributed on the edge of the pedestal and the corresponding edge of the upper cover; the folding device comprises a lower stay bar one end of which is hinged with the pedestal and an upper stay bar one end of which is hinged with the upper cover; the two stay bars are hinged with each other; and the tail of the lower stay bar is provided with a positioning back cushion. The folding crabbing cage has the advantages of simple structure, convenient operation and long service life through arrangement of the folding device between the pedestal and the upper cover. When a fishing boat sails off, crabbing cages are folded and stacked together, can be opened and put into water after arriving at crabbing sea areas, and can be folded again after crabbing, thereby the volume of the crabbing cages is reduced and the boat can carry more crabbing cages, consequently improving the crabbing efficiency.

Description

Collapsible trap for catching crabs

Technical field

The utility model relates to the fishing gear that fish at a kind of sea, specifically is meant a kind of folding trap for catching crabs easy to carry.

Background technology

The fisherman often needs to carry thousands of trap for catching crabs in order to improve crabbing efficient when going to sea, because trap for catching crabs commonly used is fixedly cage construction, so Duo trap for catching crabs need take very inconvenience of big quantity space in the ship storehouse, folding trap for catching crabs also once appearred in order to address this problem, but owing to reasons such as cost height or operation inconvenience can't volume production.The disclosed patent No. of China is " the collapsible crab pot " of " 200620140675.7 ", it adopts the structure of similar umbrella, constitute by skeleton and etting, center-pole is arranged in the skeleton, the center-pole lower end is hinged with the inclined support bar more than three radially, be with a slide block on the center-pole, be hinged with face support bar on the slide block with inclined support bar equivalent radially, nearly slide block one side of the other end of inclined support bar and face support bar middle part is hinged, long and the face support bar of the hypotenuse that the length of face support bar is right-angle side greater than the bottom circumcircle radius and the crab pot height of etting is an elastic rod, there is the detent mechanism of slide block at crab pot height place on center-pole, the top of etting and side are installed on the face support bar, and the bottom of etting is installed between the free end of face support bar.This product structure complexity the most important thing is that seawater has very strong corrosivity, uses several times and just is difficult to relative the slip with rear slider with center-pole.

The utility model content

The purpose of this utility model is at the defective of above-mentioned prior art and deficiency, for people provide folding easy to carry, trap for catching crabs that cost is low.

Technical solution adopted in the utility model is for achieving the above object: this collapsible trap for catching crabs comprises base and loam cake and is layed in base and loam cake etting outward, be evenly equipped with two to four around the described etting and enter the crab hole, be provided with folding device between the center of described base and the center of loam cake, the edge of base and the edge of corresponding loam cake be vertical to be evenly equipped with four to eight stay cords.

Described folding device comprises an end and hinged lower supporting rod and an end and the hinged last strut of loam cake of base, and two struts are mutually hinged, and the end of described lower supporting rod is provided with the location and leans on.

Described folding device comprises the knot that can be undone by a pull that is fixed in the loam cake center and vertically passes knot that can be undone by a pull and the pull bar hinged with the base center, and the upper end vertical fixing of pull bar has a cross bar, and the both sides of described knot that can be undone by a pull are provided with the groove that is complementary with cross bar.

The utility model is by being provided with folding device between base and loam cake, have simple in structure, easy to operate, the advantage of long service life.When fishing boat goes to sea, be deposited in together after crab pot is folding, open crab pot behind the arrival crabbing marine site and just can throw in, after waiting to have caught crab, crab pot can fold once more, has reduced the volume of crab pot, makes ship can carry more crab pots, has improved crabbing efficient.

Description of drawings

Fig. 1 is that the utility model first embodiment removes the etting structural representation.

Fig. 2 is that the utility model second embodiment removes the etting structural representation.

Fig. 3 is the structure enlarged drawing of Fig. 2 knot that can be undone by a pull and pull bar.

Embodiment

Embodiment 1

As shown in Figure 1, this collapsible trap for catching crabs comprises base 3 and loam cake 1, be provided with folding device between the center of the center of described base 3 and loam cake 1, a lower supporting rod 5 that this folding device one end and base are hinged and an end and the hinged last strut 4 of loam cake, two struts terminal mutually hinged, the end of described lower supporting rod 5 also are provided with the location by 6.The edge of the edge of described base 3 and corresponding loam cake 1 is vertical to be evenly equipped with four to eight stay cords 2, forms a framework, and stay cord 2 is the six roots of sensation in the present embodiment.The outside at framework is equipped with etting, is evenly equipped with two to four around the described etting and enters the crab hole.Lead in the crab hole of advancing that hand stretches on the etting and push away two strut hinged places, because stay cord 2 is to be flexible coupling, therefore the angle along with two struts diminishes, and loam cake 1 is just close with base 3, when last strut 4 and lower supporting rod 5 with overlapping, realize folding of trap for catching crabs.When the needs crabbing, pull-up loam cake 1 will be gone up strut 4 and hold up directly with lower supporting rod 5, be positioned at same straight line, and the location that makes strut 4 lean against the lower supporting rod end is leaned on 6, just can prop up trap for catching crabs.

Embodiment 2

As Fig. 2, shown in Figure 3, described folding device comprises the knot that can be undone by a pull 7 that is fixed in loam cake 1 center and vertically passes knot that can be undone by a pull and the pull bar 10 hinged with the base center, the upper end vertical fixing of pull bar 10 has a cross bar 9, and described knot that can be undone by a pull 7 is a cylinder, and its both sides are provided with the groove 8 that is complementary with cross bar.Other parts are identical with embodiment 1, are not repeated.Need when folding pull-up loam cake 1 a little and cross bar 9 is released the groove 8 of knots that can be undone by a pull, do not had the support of pull bar 10, loam cake 1 can directly be put on the base 3, and pull bar 10 was fallen, and has realized the folding of trap for catching crabs.Also only need hold up Drag link 10 and mention loam cake 1 in the time of need propping up, and the cross bar on the pull bar 10 9 be pushed in the groove 8 of knot that can be undone by a pull 7 and get final product.
