Abstract

The utility model provides a folding type crab trap pot, which comprises skeleton and webbing, wherein a centre rod (2) is provided in the skeleton, more than three inclined support bars (6) are radially hinged at the lower end of the center rod, a sliding block (4) is sheathed on the center rod, surface support bars (5) with the same quantity of the inclined support bars are radially hinged on the sliding block, the other end of the inclined support bar is hinged with one side of the surface support bar in the middle of the surface support bar and closed to the sliding block, the length of the surface support bar is larger than the excircle diameter at the bottom of the webbing and the slanting side of the triangle with the height of the crab trap pot as right-angle side, the surface support bar is elastic bar, a positioning mechanism (3) for the sliding block is arranged on the center rod at the height as that of the crab trap pot, the top and lateral surface (7) of the webbing are arranged on the surface support bar, and the bottom (8) of the webbing is arranged between the free sides of the surface support bars. When the fishing boat goes to the sea, the crab trap pot can be folded into a bundle, when arriving at the crabbing sea area, the crab trap pot can be unfolded to carry out crabbing, and after crabbing, the crab trap pot can again folded into a bundle. In this way, the hauling capacity of the fish boat can be improved.

Description

Collapsible crab pot

Technical field the utility model relates to a kind of collapsible crab pot, relates to the fold mechanism of collapsible crab pot specifically, and collapsible crab pot is used to fish for sea crab, is a kind of fishing gear.

The collapsible crab pot of background technology is for dwindling the improvement to crab pot that the shared volume of crab pot carries out when travelling to and fro between the fishing ground.Crab pot is constituted with skeleton and etting, be shaped as cylinder, collapsible crab pot in the past, a kind of is to be constituted skeleton as what Chinese utility model patent 96250012.7 " collapsible trap for catching crabs " introduced by two support rings up and down, connect by etting between the last lower support ring, and cage is opened with buoyancy that puts on ring and the gravity that puts on down ring, and be a disk after it is folding, the shape after the lower compression on the cylinder soon.Another kind is the skeleton that constitutes crab pot as the bracing frame to be with " ㄈ " type on center-pole that Chinese utility model patent 02206761.2 " collapsible crab pot " is introduced, a plurality of ㄈ when opening " bracing frame of type and centre frame constitute " in " type squirrel-cage skeleton, the bracing frame of folding back a plurality of " ㄈ " type is harmonious.Above-mentioned two kinds of collapsible crab pots still have the waste of considerable space at folding back skeleton, as preceding a kind of ring skeleton mid portion, and the mid portion of the bracing frame of back a kind of " ㄈ " type.Its skeleton of collapsible crab pot that is prior art is not accomplished to draw in fully, also has the waste of many spaces, and the transport power of crabbing operation ship is caused bigger waste.

Summary of the invention is at above-mentioned deficiency, and the utility model is exactly to propose the collapsible crab pot that a kind of skeleton can draw in fully.

The collapsible crab pot that the utility model provides, constitute by skeleton and etting, etting comprises the top, side and bottom three parts, 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 sliding shoe on the center-pole, be hinged with face support bar on the sliding shoe with inclined support bar equivalent radially, nearly sliding shoe 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 of the right angled triangle that the length of face support bar is the end 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.

The collapsible crab pot that the utility model provides, the bottom of etting is installed in a hoop net rope on the end of face support bar and is connected with the side with the top of etting, the length of said nettle is the length of side of the bottom of etting, the nettle circle is used for strengthening the intensity of the bottom of etting, reduces the pull power of face support bar to the bottom of etting when making operation.

The collapsible crab pot that the utility model provides, the skeleton structure of the approximate umbrella of its skeleton structure, inclined support bar and face support bar, center-pole constitute a triangle, change the relative size of this each interior angle of triangle by the length on a limit in the sliding slider change triangle.When shortened on this limit, the angle at these two ends, limit increased, and two support bars open; When extended on this limit, the angle at these two ends, limit dwindled, and two support bars draw in.During work, when the slide block detent mechanism was positioned at the crab pot height with slide block, the face support bar became bending the frame of crab pot and struts etting; When slide block detent mechanism release slider, slide block can upwards slide and makes inclined support bar, face support bar all receive with center-pole according to center-pole, and this moment, the harvest of crab pot skeleton was a branch of.Like this, when fishing boat went to sea, the crab pot of being adorned on the ship was a branch of for harvest entirely, opened crab pot behind the arrival crabbing marine site and just can throw in, and after waiting to have caught crab, but harvest is a branch of again for crab pot.There has not been also collapsible leeway between a branch of its skeleton of crab pot of harvest, do not had the space of waste fully, improved the transport power of crabbing fishing boat.

Description of drawings Fig. 1 is the cutaway view of the utility model one embodiment, be user mode, among the figure: the 1-lifting rope is used for the crab pot seabed operation that hangs down, 2-center-pole, the detent mechanism of 3-slide block, the 4-slide block, 5-face support bar, 6-inclined support bar, the top of 7-etting and side, the bottom of 8-etting and nettle;

Fig. 2 is the structural representation after skeleton draws among Fig. 1, among the figure: 1-lifting rope, 2-center-pole, 3-positioner, 4-slide block, 5-face support bar, 6-inclined support bar.

Embodiment as shown in Figure 1, 2, one lifting rope 1 is arranged, there is a center-pole 2 in end system, the lower end of center-pole by branches such as circumference be hinged with 6 inclined support bars 6, be with a slide block 4 on the center-pole, on the slide block by branches such as circumference be hinged with 6 flexible flexible support bars 5, inclined support bar and face support bar are hinged correspondingly, both pin joints be inclined support bar not with the hinged end of center-pole and face support bar from 1/4 place of the hinged end of slide block.Slide block detent mechanism 3 is arranged on the center-pole, is a wedge-like lug with the spring support, and the hypotenuse of wedge-like upwards.The bottom 8 of etting is regular hexagon, has a nettle to seize and become a circle on hexagon, and these hexagonal six angles are installed on six free ends of face support bar through the nettle circle respectively.When slide block slides hypotenuse on lug, lug is pressed in the center-pole, when slide block slips over convex plate position, projection ejects center-pole a little less than by spring, fasten the slide block location, the bottom constraint of this moment as no etting, the face support bar will directly be opened, but the hexagon that its end points enclosed is greater than the hexagon of the bottom of etting, and its vertical range to slide block is less than the height of crab pot.Because the face support bar is flexible flexible, install the bottom of etting on the support bar free end face to face after, the bending that just is tied of face support bar increases the space of being shrouded, and makes vertical height between the face at place, end and slide block become the height of crab pot simultaneously.The top of etting and side 7 are a dome shape and cover on outside the face support bar, and its bottom links to each other with the bottom sides of etting, arrange an openning that allows crab climb between per two face support bars, and the center-pole lower end hangs bait box.
