Obviously, the described The embodiments of the present invention are a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Accordingly, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Example 1:

Please refer to FIG. 1 and FIG. 2 , this embodiment provides a crab cage hook, which includes a cage hook assembly and a supporting transverse plate.

The cage hook assembly includes the connected middle ring 11 and the bottom ring 12, the movable rod 13 connected with the middle ring 11, and the hook rod 19 connected with the bottom ring 12; The shackle 9; the end of the movable rod 13 remote from the intermediate ring 11 is adapted to be inserted into the shackle 9 to form a closed annular cage. It should be noted here that the length of the end of the movable rod 13 after being inserted into the shackle 9 from the shackle 9 should not be too long, as too long will cause difficulty in decoupling, and it should not be too short, as too short may easily cause crabs. The cage hook 23 falls off during the recovery process.

The supporting transverse plate, the movable rod 13 is adapted to pass through the supporting transverse plate, and the part of the movable rod 13 inserted into the supporting transverse plate is fixedly connected with the supporting transverse plate. It should be noted here that, in order to facilitate manual control of the support horizontal plate, the length between the two ends of the support horizontal plate in the width direction should not be too long, and it is appropriate that the two ends of the support horizontal plate can be clamped by the thumb and index finger of a person. Of course, optionally, the two ends in the length direction can also be controlled by manually controlling the support cross plate. At this time, there is no absolute requirement for the length between the two ends in the width direction of the support cross plate.

Specifically, the middle ring 11 and the bottom ring 12 are connected by a connecting rod 25; the middle ring 11, the connecting rod 25, the bottom ring 12, the movable rod 13, the hook rod 19 and the shackle 9 are all bent with the same steel bar. and the angle formed between the connecting rod 25 and the hook rod 19 is an acute angle; the angle formed between the connecting rod 25 and the movable rod 13 is an obtuse angle; the angle formed between the hook ring 9 and the hook rod 19 is Obtuse angle; bottom ring 12 is suitable for connecting with crab cage 3. The middle ring 11 and the bottom ring 12 are both of helical structure to form an elastic ring. The main significance of such a design is to improve the elasticity of the middle ring 11 and the bottom ring 12 .

In the process of specifically manufacturing the cage hook assembly, a shackle 9 formed by bending one end of a steel bar is used. The shackle 9 extends downward to form a hook rod 19, and the bottom of the hook rod 19 is bent to form a bottom loop 12. The other end of the ring 12 extends obliquely upward to a quarter position and is bent to form an intermediate ring 11, and the other end of the intermediate ring 11 extends to form a movable rod 13. The integral cage hook assembly is easy to manufacture and can be completed without extra accessories. Bend forming of the integral cage hook assembly.

Among them, the design of the middle ring 11 is mainly used to enhance the elasticity of the overall cage hook assembly, so as to facilitate decoupling (that is, the movable rod 13 is detached from the shackle 9), and can also provide a buffering effect during decoupling to avoid the crab cage hook 23 Deformation occurs when the impact is violent. The crab pot hook 23 is installed on the crab pot through the bottom ring 12. It should be noted here that the crab pot 3 can directly pass through the bottom ring 12 through the rope loop to realize the connection between the crab pot 3 and the bottom ring 12. Specifically, this embodiment It is not absolutely limited, that is, as long as the crab pot 3 can be connected with the bottom ring 12 so that the crab pot 3 in the whole crab pot hook 23 is at the bottom of the crab pot hook 23 in the pulling state.

More specifically, the lengths of the connecting rods 25 are all smaller than the lengths of the hook rods 19 and the movable rods 13 ; and the middle part of the movable rods 13 is fixedly connected with the support transverse plate. The main significance of such a design is that the support cross plate can form the base point for the adjustment of the interlocking and disengaging states between the movable rod 13 and the hook and loop 9, that is, the support cross plate is relatively fixed, so that the support cross plate is in a fixed position. At this time, when the movable rod 13 is relatively fixed, and then the shackle 9 is subjected to tension, since the steel bar itself that makes the crab cage assembly has a certain deformation effect, the shackle Applying a pulling force can cause the shackle 9 and the hook rod 19 to produce corresponding micro-deformation, and finally the shackle 9 can be detached from the end of the movable rod 13, so as to completely realize the detachment effect of the movable rod 13 and the shackle 9.

Please refer to FIG. 3 , and more specifically, the supporting transverse plate in this embodiment includes a male transverse plate 10 and a female transverse plate 14 that are suitable for mating; the male transverse plate 10 and the female transverse plate 14 can optionally use bolts 16 To achieve a fixed mating between the two. The end face of the male cross plate 10 facing the female cross plate 14 is provided with a T-shaped raised portion 18; The T-shaped protrusion 18 and the end face of the anti-falling protrusion 17 away from the male horizontal plate 10 are flush and coplanar; The end of the female transverse plate 14 facing the male transverse plate 10 is provided with a T-shaped convex portion 18 and an anti-separation convex column 17 and a concave groove 141 .

Optionally, in order to enable the anti-separation protruding post 17 to achieve the limiting and anti-removing effect on the U-shaped winding body, the diameter of the end of the anti-dropping protruding post 17 away from the male transverse plate 10 is larger than the diameter of the anti-dropping protruding post 17 and the wing. The diameter of the ends connected by 182 , that is, after the U-shaped body is wound around the anti-separation protrusion 17 , the end of the anti-separation protrusion 17 away from the male transverse plate 10 forms a stop for the U-shaped body. Of course, optionally, the anti-separation protruding column 17 can also be provided with a limit groove suitable for U-shaped winding on the side wall, so that the U-shaped winding is partially embedded in the limit groove of the anti-separation protruding column 17 , which can also avoid the problem of falling off of the U-shaped body.

Example 2:

Referring to FIGS. 4 to 6 , on the basis of the crab cage hook 23 in Embodiment 1, this embodiment provides an automatic decoupling and recovery device, including: a support frame 1 and a flip plate arranged in the support frame 1 mechanism, crab cage traction mechanism and crab cage decoupling mechanism.

The crab cage traction mechanism includes a main traction rope 5 and a plurality of traction rings 24 arranged on the main traction rope 5 at intervals; . The plate-turning mechanism includes a recovery plate 6 that is hingedly connected to the support frame 1 and is suitable for swinging around the frame. Several traction rings 24 are used to respectively pull several crab cage hooks 23, that is, several crab cages 3, so as to satisfy the process of pulling the main traction rope 5, a certain number of crab cages 3 corresponding to the number of traction rings 24 can be removed. Requirements.

The crab cage hook 23 of the present embodiment is assembled with the traction ring 24 in this way. The worker presses the bottom ring 12 against the palm, and two fingers respectively hook the two ends of the supporting horizontal plate, and grasp with force to make the movable rod 13 come off the hook. The loop 9 forms a rope-off opening, slide the traction loop 24 between the movable rod 13 and the shackle 9, release the two ends of the supporting cross plate with fingers, and then release it due to the restoring force of the middle loop 11 and the bottom loop 12, and then move. The rod 13 is inserted into the shackle 9, the traction ring 24 is fastened in the crab cage hook 23, and a crab cage hook 23 is hung on the traction ring 24.

The crab cage decoupling mechanism includes a decoupling plate 7 arranged on the support frame 1, and an anti-collision tube 20 movably assembled with the decoupling plate 7; the anti-collision tube 20 is a hollow tube structure along its axial direction; the nozzle of the anti-collision tube 20 The inner diameter is smaller than the length of the supporting transverse plate of the crab pot hook 23 .

Please refer to FIG. 6 , specifically, the decoupling plate 7 is provided with a mounting hole for assembling with the anti-collision tube 20 (not marked in the drawings in this embodiment); and the anti-collision tube 20 is located at the end of the decoupling plate 7 . A limit plate 26 is sleeved, and the end of the anti-collision tube 20 located under the decoupling plate 7 is provided with an outer folded edge 27 facing the opposite direction of the nozzle of the anti-collision tube 20; An R-angle structure is formed therebetween. The design of the R-angle structure can reduce the wear on the main traction rope 5 and prevent the upper end of the movable rod 13 from being bent when unhooked.

In order to prevent the main traction rope 5 from colliding with the crab cage hook 23 too quickly during the rope retracting process, a buffer spring 21 is sleeved on the outer peripheral side of the anti-collision tube 20, and the buffer spring 21 plays a certain buffering role. Specifically, one end of the buffer spring 21 is adapted to abut against the lower end surface of the release plate 7 ;

In order to limit the guide trajectory of the main traction rope 5, the automatic decoupling and recovery device further includes a guide mechanism suitable for guiding the movement of the main traction rope 5; 8; The main traction rope 5 is suitable for winding the traction guide wheel 8 and then passing through the anti-collision tube 20 and then winding on the rope guide wheel 2. Wherein the traction guide wheel 8 is located below the recovery plate 6, and the guide wheel 2 is located above the decoupling plate 7; and the outer diameter of the traction guide wheel 8 is greater than the outer diameter of the pulley 2, and the axial length of the traction guide wheel 8 is greater than The axial length of the sheave 2. It should be noted here that the design of the traction guide wheel 8 has two functions. The middle groove on the traction guide wheel 8 is used to guide the main traction rope 5 to pass through the middle, so that the main traction rope 5 will not shift left and right and cause crab cages. swing. The overall structure of the traction guide wheel 8 is larger than that of the rope guide wheel 2 , so that the crab cage can be quickly stabilized when it hits the traction guide wheel 8 , which facilitates the subsequent and stable folding of the flap 601 mechanism.

In order to limit the swing angle of the recovery plate 6 of the flap mechanism, the flap mechanism further includes a pair of limiters suitable for limiting the swing angle of the recovery plate 6 , which are arranged on the support frame 1 and located on both sides of the recovery plate 6 in the length direction. Bit block 4. The recovery plate 6 is composed of two flaps 601 that can be turned up and a flat plate 602. The flap 601 and the flat plate 602 are integrally connected; the overall recovery plate 6 and the support frame 1 are hinged through a hinge shaft, and the assembly position of the hinge shaft is It is preferably arranged at the junction of the flap 601 and the flat board 602. In the normal initial position, since the weight of the flat board 602 is greater than the sum of the weights of the two flaps 601, the recovery board 6 as a whole and the bottom end surface of the support frame 1 are formed. For example, but not limited to a 45-degree angle, the recovery plate 6 is inclined relative to the bottom end surface of the support frame 1 , that is, the recovery plate 6 forms a slope relative to the bottom end surface of the support frame 1 . Under the pulling force of the main traction rope 5, the crab cage 3 located below the flap 601 turns the flap 601 upward ("upward" here means swinging around the hinge axis toward the side of the limit block 4), so that the flap 601 is turned up. After the 601 is turned up, the crab cage 3 located under the flap 601 will not form a resistance that rises with the pulling force of the main traction rope 5. In this way, the crab cage 3 located under the flap 601 will smoothly pass the position of the original flap 601. , and after the crab cage 3 located under the flap 601 passes smoothly, the flap 601 returns to its original position under the action of gravity (that is, the recovery plate 6 forms a slope relative to the bottom end surface of the support frame 1), during this process In the middle, the limit block 4 can prevent the flipping plate 601 from being turned up at an angle exceeding 90° and unable to return to the original position.

For this embodiment, the recovery plate 6 is mainly used to receive the crab cage 3 that moves to the top of the flap 601 under the action of the main traction rope 5. After the crab cage hook 23 is separated from the traction ring 24, the crab cage 3 can follow the crab cage. The hooks 23 can be dropped together on the slope formed by the recovery plate 6 relative to the bottom end face of the support frame 1, and then automatically slide down to the boat through the action of the slope of the recovery plate 6. In this way, there is no need for workers to drag the crab cage hook 23 relative to the traction. When the ring 24 is unhooked, it grabs the crab pot 3. It should be noted here that although the recovery plate 6 is in the initial state relative to the slope formed by the bottom end surface of the support frame 1 , the crab cage 3 located above the flap 601 is released relative to the traction ring 24 along with the crab cage hook 23 . The weight of the crab cage and the crab cage hook 23 will produce a certain heavy pressure on the flip plate 601, but the weight of the crab cage and the crab cage hook 23 will not cause the flip board 601 to move towards the deviation limit. One side of the block swings, because a plurality of traction rings 24 are provided on the main traction rope 5. When the crab cage 3 located above the flap 601 falls on the flap 601 together with the crab cage hook 23, it is located on the flap 601. The crab cage 3 carried by the crab cage hook 23 pulled by the other traction ring 24 below the 601 will form a certain supporting and abutting effect on the bottom of the flap 601, which can overcome the pair of the crab cage 3 and the crab cage hook 23 above the flap 601. The pressure generated above the flap 601 corresponds to the possible tendency of the flap 601 to turn down.

Optionally, a baffle 22 is further provided on the support frame 1, and the baffle 22 is designed to prevent the crab cage 3 from falling into the sea after being unhooked.

The specific implementation principle of the automatic decoupling recovery device of this embodiment is as follows: because the inner diameter of the orifice of the anti-collision tube 20 equipped with the decoupling plate 7 is smaller than the length of the supporting transverse plate of the crab cage hook 23, under the pulling of the main traction rope 5, Both ends in the width direction of the support cross plate are stuck on the edge of the nozzle of the anti-collision tube 20, the support cross plate presses the buffer spring 21, and continues to move with the main traction rope 5 until the buffer spring 21 is compressed to the shortest, and the support cross plate is relatively limited. Its movement trajectory cannot continue to move, that is, the movement of the movable rod 13 is also limited. At this time, the pulling force of the main traction rope 5 mainly acts on the shackle 9. With the continuous application of the pulling force, the shackle 9 and the hook rod 19 It will gradually overcome the weight of the crab cage 3, so that the shackle 9 and the hook rod 19 will have a certain micro-deformation, that is, the angle between the shackle 9 and the movable rod 13 will gradually become smaller, and finally the movable rod 13 will come out of the shackle 9 ring. A rope-off opening is formed, the crab pot hook 23 falls off from the traction ring 24, and the crab pot 3 falls on the slope formed by the recovery board 6 along with the crab pot hook 23, and automatically slides down to the boat, without the need for workers to catch it when the hook is released. Crab Pot 3. Then the main traction rope 5 continues to pull the next crab cage hook 23 with the crab cage 3, repeats the above-mentioned decoupling process, and takes off the crab cage hooks 23 and crab cages 3 arranged on the main traction rope 5 in turn, so that the workers can carry out subsequent crab extraction, Arrange the crab pot 3 and other process actions.
