Abstract

The utility model relates to a folding crab trapping cage which is composed of a net which is coated and fixed between upper and lower supporting rings and is provided with a plurality of inducing ports. The upper supporting ring is provided with an annular float. The upper supporting ring floats and the lower supporting ring sinks depending on the buoyancy of the float and the dead weight of the lower supporting ring in water, so the utility model can automatically open and can automatically retracted into a shape with a small volume when the utility model is lifted. Compared with a traditional crab trapping cage in which the net with a plurality of inducing ports is coated and fixed outside a saucer spring and is fully operated by man-power, the utility model has the effect of labor saving and time saving, and raises the trapping rate.

Description

Collapsible trap for catching crabs

The utility model relate on a long support rope, bind at certain intervals a plurality of, it is dropped in water, lure the trap for catching crabs of catching crab.

Traditional this type of trap for catching crabs and aftermentioned structure shown in Figure 4 are much the same, owing to be to be coated and fixed in the outside of saucerspring 10 with having a plurality of nets of mouth of luring, when leaving the port need to saucerspring fully push form flat condition after, on the opposite side of saucerspring, hang up the contraction operation that hook 11 makes volume-diminished, also to carry out hook is taken off, make the open operation of trap for catching crabs, these operations all are to rely on manpower to carry out fully on fishing operation field, need to consume a large amount of manpowers and time, thereby exist because of depending on manual operation, activity duration is long, is difficult to the problem that capture rate is improved.

Therefore, the utility model purpose is to provide can open automatically in water, draws in automatically when mentioning, can save manpower and time, the collapsible trap for catching crabs that capture rate is improved.

According to the collapsible trap for catching crabs of the utility model, be coated and fixed at the metal support interannular of top and the bottom forming a plurality of little nets of luring mouth of disconnected stenosis to the inside that pursue, the annular float that is formed by foamed synthetic resin is fixed on the upper metal support ring of trap for catching crabs, hooking part is tied up on the long support rope, then it is dropped in the water.

When throwing above-mentioned trap for catching crabs in water, its upper metal support ring floats because of the buoyancy of float, and its underpart metal support ring sinks because of the weight of himself, thereby automatically trap for catching crabs is opened, and in addition, it is very little to draw into it in volume naturally when last carrying.Thereby have labour and the time that to save the fisherman significantly and can make and catch the effect that operating efficiency significantly improves.

Below, with reference to accompanying drawing the utility model embodiment is described.

Fig. 1 is the stereogram of the utility model example structure,

Fig. 2 is the profilograph of said structure,

Fig. 3 is the profilograph of said structure rounding state,

Fig. 4 is the figure of the traditional trap for catching crabs of expression.

Be coated and fixed in upper

metal support ring

2 and 3 trap for catching crabs of forming 1 of lower metal support ring by having a plurality of nets 4 of mouth 5 of luring, the float of making according to the shape of upper metal support ring 2 with foamed synthetic resin 6 is fixed on the upper metal support ring 2, in addition, float 6 also can be made of hollow tube.After tying up to a plurality of the utility model trap for catching crabs 1 on the long support line 12 with hook member 7 at regular intervals, drop in the water, can carry out usual seizure crab operation.

The utility model since with upper metal support ring 2 and lower support ring 3 be fixed on net about, float 6 is fixed on the upper metal support ring 2, so the buoyancy that relies on float 6 floats upper metal support ring 2 in water when, make lower metal support ring 3 rely on the weight of self and sink.

Therefore, trap for catching crabs 1 is automatically opened in water forms and the same state shown in Figure 2.Make float if consider the buoyancy size of float 6 again, just can regulate the submergence depth of trap for catching crabs 1.

And, when on trap for catching crabs 1, carrying, rely on the weight of lower metal support ring 3 automatically it to be drawn in as Fig. 3, volume to be shortened into very little, owing to just the crab that catches can be taken out as long as open peristome, thereby not worry because of drawing trap for catching crabs 1 in be difficult to problem with the crab taking-up with snap close 8.

Therefore, according to aforesaid the utility model, because when dropping into it in water, can rely on the weight of the buoyancy be fixed on the float 6 on the upper metal support ring 2 and lower metal ring 3 and automatically open, when last carrying, can draw into the very little shape of volume automatically in, thereby has manpower and the time that to save the crabbing operation to greatest extent, the effect that capture rate is improved.

Claims

1. collapsible trap for catching crabs, constitute by the net (4) that is coated and fixed on supporting member, has a plurality of luring (5), it is characterized in that described supporting member is upper support (2) and lower support ring (3), described net (4) is coated and fixed between upper supporting ring (2) and lower support ring (3), the float (6) that can produce buoyancy in water is fixedly installed on the upper support ring (2).
