Description

Mechanical trigger and its catching device TECHNICAL FIELD

[0001] The present application relates to the field of aquatic tools, in particular to a mechanical trigger and a catching device designed based on the mechanical trigger. BACKGROUND

[0002] There are various crab catching devices on the market, all of which place bait in the device to lure crabs for catching. However, when the crabs eat the bait, they cannot generally obtain the signal of the crabs eating the bait in time, especially in the case of wind and waves, especially in the marine environment. The reason may be related to the unique eating habits of crabs.

[0003] The Chinese patent "Crab fishing tackle" with patent number CN213486499U, the inventor writes in the patent about the part of the crab eating bait: "When the crab finds the bait, it will approach the bait and insert the chela or step foot into the hoop 5 to clamp the bait, at this time, immediately lift the rod, and the crab can be tightly sleeved and lifted by the hoop 5", the patent does not mention how the crab catcher knows that the crab has found the bait and clamped the bait. Moreover, for such a catching device using a hoop (rope sleeve), whether the crab enters the sleeve is a probability problem.

[0004] The Chinese patent "Novel crab catching cage" with patent number CN216853498U, the inventor writes in the patent about the part of the crab eating bait: "When the crab climbs onto the stainless steel wire 12 to eat the bait, hold the nylon fishing line 14 and lift it upwards", the patent also does not mention how the crab catcher knows that the crab is eating the bait.

[0005] The Chinese patent "Connection body of float rod and bait hook and fishing tackle with the connection body" with patent number CN214257682U, the inventor writes in the patent about the part of the crab eating bait: "When fish, shrimp, crab and other aquatic organisms eat, the bait hook moves violently, the eight-shaped ring and the float rod connected with the bait hook also move, and because the upper part of the float rod is provided with a ring, the ring is pressed on the net collecting line, so the net collecting line also moves, the fishing line connected with the net collecting line and the float on the fishing line also move on the water surface, at this time, the angler lifts the fishing rod", the patent specially designs a device for catching the signal of the crab eating bait. However, after the author bought and actually used this patent fishing tackle, it was found that in the case of calm wind and waves, the signal of the crab eating bait can be obtained in time, but the intensity is weak. In the case of wind and waves, especially in the sea, the signal of the crab eating bait cannot be obtained in general. SUMMARY

[0006] The technical problem solved by the present application is to provide a crab baiting device that can produce a clear signal in time when the crab is eating bait, and output a powerful mechanical trigger, and to upgrade the existing crab catching device based on the mechanical trigger, and design a new automatic crab catching device and a manual crab catching device.

[0007] To solve the above technical problems, the present application adopts the following technical solutions:

[0008] A mechanical trigger includes a bait protection structure, a bait taking opening, a bait hanging component, a force transmission component, and a support component. The bait taking opening is located on the bait protection structure, the bait hanging component is located inside the bait protection structure, the force transmission component is combined with the bait hanging component, and the support component provides support and support for the bait hanging component and the force transmission component.

[0009] The bait protection structure is an obstacle between the bait hanging component and the target crab, which prevents the target crab from directly contacting the bait on the bait hanging component. The so-called target crab cannot directly contact the bait on the bait hanging component means that the target crab needs to overcome the obstacle or bypass the obstacle before contacting the bait, which is relative to the target crab that can directly contact the bait on the bait hanging component. The so-called target crab that can directly contact the bait on the bait hanging component means that there is no obstacle between the target crab and the bait on the bait hanging component, and the target crab can directly contact the bait on the bait hanging component without any obstruction.

[0010] The bait taking opening is a gap opened on the bait protection structure, which is a channel allowing the target crab to contact the bait on the bait hanging component inside the bait protection structure. The target crab can extend its claws or feet into the bait protection structure through the bait taking opening to contact the bait on the bait hanging component, or the target crab can drill into the bait protection structure through the bait taking opening to contact the bait on the bait hanging component. If the target crab wants to eat the bait on the bait hanging component, it first needs to overcome the obstruction of the bait protection structure and find the bait taking opening on the bait protection structure.

[0011] The design idea of the bait protection structure and the bait taking opening is that the target crab can only extend its claws or feet into the bait protection structure through the bait taking opening to contact and pull the bait on the bait hanging component, or the target crab can drill into the bait protection structure through the bait taking opening to contact the bait on the bait hanging component, but cannot stay in the bait protection structure to eat the bait normally. The target crab can only drag the bait out to eat it well.

[0012] The bait hanging component includes but is not limited to structures that can hang or tie or wrap the bait, such as fish hooks, fish forks, bait net pockets, and wire bait cages.

[0013] The force transmission component is an object that can transmit force, such as fishing line, steel wire, and lever.

[0014] The support component is a structure that can make the bait hanging component and the force transmission component stay in a certain position relative to the bait protection structure, can perform the function of the bait hanging component and the force transmission component, and can provide necessary support and support.

[0015] The force transmission component and the bait hanging component are combined with each other, and the support component provides support and support for the bait hanging component and the force transmission component, and can connect the force transmission component and the bait hanging component together, which is called a connecting body. One end of the bait hanging component of the connecting body is inside the bait protection structure, and the other end is outside the bait protection structure. The support component provides support and support for the connecting body in this position relative to the bait protection structure and the function thereof.

[0016] The force transmission component and the bait hanging component can also be integrated into one, which is called a combination body. One end of the bait hanging component of the combination body is inside the bait protection structure, and the other end is outside the bait protection structure. The support component provides support and support for the combination body in this position relative to the bait protection structure and the function thereof.

[0017] The force transmission component can also be located around the bait hanging component. The support component provides support and support for the bait hanging component inside the bait protection structure and the function thereof, and provides support and support for the force transmission component around the bait hanging component and the function thereof.

[0018] An automatic trap device comprises a mechanical trigger, a switch module, a power module, and a trapping module. The mechanical trigger controls the switch module, the switch module controls the power module, and the power module drives the trapping module.

[0019] The trapping module can be a device capable of trapping a part of a crab's body, such as a rope sleeve or a clamp. It can also be a device capable of trapping the entire body of a crab, such as a net, a net clamp, a net cage, or a wire cage.

[0020] The power module is a device that provides the required power for the trapping module to capture, such as a spring, a rubber band, or a glass fiber rod. It can also be a combination of elastic objects. When an external force acts on the power module, the power module deforms and stores energy. After the external force disappears, the power module returns to its original state and generates a restoring force, which drives the trapping module. The force that makes the elastic object return to its original state after deformation is called the elastic force.

[0021] The switch module is a device that can maintain the deformed state of the power module and can control the power module to return to its original state. When an external force acts on the power module, the power module deforms, and the switch module closes to maintain the deformed state of the power module. After the switch module is opened, the power module releases energy and returns to its original state. When the automatic trap device is working, the mechanical trigger provides the force required to open the switch module to control the opening of the switch module.

[0022] A kind of automatic organ trap device organ rope sleeve box, belong to the aforementioned one kind of automatic organ trap device, when the capture module is rope sleeve, rope sleeve is located at bait opening, when being in capture state, rope sleeve main part is substantially coincident with bait opening;The power module is spring, spring is installed on bait protection structure, spring is connected with rope sleeve.

[0023] A kind of automatic organ trap device organ clamp box, belong to another kind of the aforementioned one kind of automatic organ trap device, when the capture module is clamp, the power module is spring, spring is installed on bait protection structure;The first clamping part of clamp is the end of spring, the other clamping part is the bait protection structure body at bait opening.

[0024] For the above two kinds of automatic organ trap device, the switch module is lock catch and pressure rod, lock catch and pressure rod are used in combination, and are combined with spring and bait protection structure together;The force transmission component of mechanical trigger is connected to lock catch, and is responsible for the opening of lock catch.

[0025] The switch module is lock catch and pressure rod, lock catch and pressure rod are used in combination, and are combined with spring and bait protection structure together;Lock catch and pressure rod can be selected as two components, and are used in cooperation, one end of lock catch is connected to bait protection structure or spring, and the other end is connected to the force transmission component of mechanical trigger, one end of pressure rod is connected to bait protection structure or spring, and the other end cooperates with lock catch.

[0026] Lock catch and pressure rod can also be selected to be combined into one, and pressure rod is fused into lock catch, or pressure rod is omitted, in terms of physical form and function, the switch module is a lock catch, one end of lock catch is connected to bait protection structure or spring, and the other end is connected to the force transmission component of mechanical trigger, at this time, a plug connector needs to be provided on spring, for cooperating with lock catch.

[0027] A kind of automatic organ trap device organ net clamper and a kind of automatic organ trap device organ net disc clamp, belong to the other two kinds of the aforementioned one kind of automatic organ trap device, when the capture module is net clamper, mechanical trigger is combined with net clamper together, the power module is spring, spring is combined with net clamper together, net clamper opens when spring opens, and the rebound force of spring opening promotes net clamper to close;The switch module is lock catch and pressure rod, lock catch and pressure rod are used in combination, and are combined with net clamper together;The force transmission component of mechanical trigger is connected to lock catch, and is responsible for the opening of lock catch.

[0028] The switch module is lock catch and pressure rod, lock catch and pressure rod are used in combination, and are combined with net clamper together at this time;Lock catch and pressure rod can be selected as two components, and are used in cooperation, one end of lock catch is connected to net clamper, and the other end is connected to the force transmission component of mechanical trigger, one end of pressure rod is connected to net clamper, and the other end cooperates with lock catch.

[0029] The lock catch and the pressure rod can be combined into one, and the pressure rod is fused into the lock catch. In terms of physical form and function, the switch module is a lock catch. One end of the lock catch is connected to the net clamp, and the other end is connected to the force transmission component of the mechanical trigger. At this time, a plug connector needs to be set on the net clamp for cooperation with the lock catch.

[0030] A kind of opening and closing structure capture device, including a mechanical trigger described above, opening and closing capture module;Opening and closing capture module includes opening and closing cage net body, elastic component, centralizing component, pull rope;Elastic component is arranged on opening and closing cage net body, controls the opening of opening and closing cage net body, pull rope is connected after opening and closing cage net body passes through centralizing component, pull rope and centralizing component cooperate to control the closure of opening and closing cage net body, bait protection structure is installed on opening and closing cage net body, centralizing component is connected with force transmission component.

[0031] The opening and closing capture module can be automatically opened by the elastic force of the elastic component, and some are also attached to the gravity of the self component or only rely on the gravity of the self component. Under the action of external force, the external force overcomes the resistance of the force that makes it open, and makes the opening and closing capture module close. The elastic component is generally a spring, but it can also be a rubber band, a glass fiber strip, etc. It can also be a combination of several elastic objects. The function of the centralizing component is to bundle the pull rope together, change the direction of the pull rope, so that the opening and closing cage net body can be closed smoothly and as tightly as possible. When the force transmission component of the mechanical trigger is pulled, the centralizing component connected with the force transmission component touches the pull rope and pulls the main line to generate a signal.

[0032] The idea of opening and closing the capture module comes from the commonly used opening and closing capture device in the prior art. Currently, there are three commonly used opening and closing capture devices, namely, a spherical opening and closing cage, mainly from Korean Patent No. KR2020090012433U, entitled "Capture Structure for Fresh water Crab Fish", Chinese Patent No. CN216853498U, entitled "A New Type of Crab Trap Cage", and Chinese Patent No. CN214257682U, entitled "A Connection Body of a Floating Rod and a Bait Hook and a Fishing Tackle Having the Connection Body"; a tower-shaped opening and closing cage, mainly from US Patent No. US19080433438A, entitled "CRAB-TRAP", US Patent No. US19120721223A, entitled "KNOCKDOWN CRAB-TRAP", and US Patent No. US19150058374A, entitled "CRAB-TRAP"; and a net clamp, mainly from UK Patent No. GB8332188A, entitled "CLAPTRAP", and US Patent No. US19770762039A, entitled "Book net for crabs, lobsters, and the like". In terms of structure and function, the opening and closing cage net body, the elastic component, the bait hanging component, the wire collecting component, and the pull rope are the five main parts, and the bait hanging component and the wire collecting component are usually connected and integrated together. In an invention patent entitled "A Switch Trigger and Its Alarm System and Capture Device", three kinds of opening and closing capture devices are described in detail. The opening and closing structure capture device described in this paper mainly installs the mechanical trigger in this paper on the opening and closing cage net body to replace the original bait hanging component, and then connects the force transmission component to the wire collecting component.

[0033] A rope sleeve capture device, comprising a mechanical trigger as described above, a rope sleeve; the rope sleeve is connected to the bait protection structure; the rope sleeve connected to the bait protection structure can be directly connected or indirectly connected.

[0034] The rope sleeve is made of a rope, one end of which is knotted into a small loop, and the other end passes through the small loop to form a live buckle. After trapping the object, the live buckle becomes tighter and tighter, and the rope can be a fishing line or a steel wire.

[0035] There are many kinds of existing rope sleeve catching devices, and their basic structural functions can be summarized as rope sleeve base, bait hanging component, and rope sleeve three parts. The rope sleeve base can be a bait cage, such as the bait cage used in the US patent "Castable crab trap" with application number US20060645957A and the Chinese patent "Simple crab bait cage" with application number CN201820248276.5; it can be an iron ring, such as the ring-shaped rope sleeve mounting device used in the US patent "Crab trap apparatus" with application number US19910783522A and the Chinese patent "Crab fishing tool" with application number CN201420627145.X; it can be a circular metal sheet with holes, such as the circular flat plate used in the Chinese patent "Net line buckle and crab fishing tool" with application number CN202122440123.5; it can also be a metal wire kneaded support, such as the support leg and framework used in the patent "Crab fishing tool" with patent authorization number CN213486499U. There is also a detailed description of this in a patent named "Switch trigger, its alarm system and catching device". The rope sleeve catching device of the present invention basically replaces the rope sleeve base and bait hanging component with a mechanical trigger.

[0036] A claw sleeve structure catching device, including a rope sleeve catching device as described above, and a wire arrangement component; at this time, the bait protection structure is a claw-shaped bait protection structure, which includes a central body and claws, and the claws are at least three, distributed around the central body; the bait taking opening is located on the claw-shaped bait protection structure, specifically the opening formed between adjacent claws and the ground surface when the claw-shaped bait protection structure is erected; the rope sleeve is connected to the claw-shaped bait protection structure, and the wire arrangement component is arranged on the claws, under the action of the wire arrangement component, the rope sleeve is unfolded around the bait taking opening;

[0037] The support component can be a hole provided on the central body of the claw-shaped bait protection structure, and the force transmission component is connected to the bait hanging component after passing through the support component, and the bait hanging component cannot pass through the support component;

[0038] The support component can also be a hole provided on the central body of the claw-shaped bait protection structure and a wire supporting rod connected to the central body, one end of the wire supporting rod is connected to the central body, the other end is connected to the force transmission component, and the other end of the force transmission component passes through the hole provided on the central body; at this time, the bait hanging component can be a section of the force transmission component connected to the wire supporting rod inside the bait protection structure, and can also be a bait hanging component connected to the section of the force transmission component connected to the wire supporting rod inside the bait protection structure; in use, the main line is connected to the end of the force transmission component passing out of the hole provided on the central body.

[0039] The claw-shaped bait protection structure is similar to an open claw and also similar to a bacteriophage. The claw can be made of a wire, such as a copper wire or a steel wire. In this case, the central body can be formed by winding the claw at one end of the wire together, welding the claw at one end of the wire together, or winding the claw at one end of the wire together. Alternatively, the claw-shaped bait protection structure can be a section of iron pipe, with the claw at one end welded to the iron pipe. Alternatively, the claw-shaped bait protection structure can be a plastic part with a hole, with the claw at one end inserted into the hole of the plastic part. Alternatively, the claw can be made of plastic, and the claw and the central body can be integrally formed by injection molding.

[0040] The wire arrangement component can be a plastic clip, which is spacedly distributed on the claw. Alternatively, the wire arrangement component can be a plastic strip with a clip groove, which is sleeved on the claw. Alternatively, the wire arrangement component can be a clip groove formed on the claw, which is integrated with the claw. The plastic can be a hard plastic, a soft plastic, a silica gel, a latex, or a rubber. The wire arrangement component allows the rope to be embedded in the clip opening or the clip groove, so that the rope is not easily pulled out when the bait is thrown or impacted by water flow. However, when an external object is hung on the bait, the rope can be easily pulled out. The rope is wound around the bait opening to expand, and the movable buckle of the bait is roughly distributed around the bait opening, and roughly coincides with the boundary of the bait opening.

[0041] A simple claw sleeve structure catching device includes a bait protection structure, a bait taking opening, a bait hanging component, a supporting component, a wire arrangement component, and a rope. In this case, the bait protection structure is a claw-shaped bait protection structure, which includes a central body and claws. The claws are at least three, and the claws are distributed around the central body. The bait taking opening is located on the claw-shaped bait protection structure, and specifically, the opening is formed between adjacent claws and the ground surface when the claw-shaped bait protection structure is erected. The rope is connected to the claw-shaped bait protection structure, and the wire arrangement component is arranged on the claw. Under the action of the wire arrangement component, the rope is expanded around the bait taking opening. The bait hanging component is connected to the bait protection structure and located inside the bait protection structure. The supporting component is the bait protection structure body at the connection between the bait hanging component and the bait protection structure. In use, the main line is connected to the central body.

[0042] The two claw sleeve structure catching devices described above can further include a lead sinker. The position of the lead sinker is arranged to ensure that the center of gravity of the combination of the claw-shaped bait protection structure, the wire arrangement component, and the rope is deviated to the lower part of the combination and deviated from the upper part where the central body of the claw-shaped bait protection structure is located. In this way, after the combination enters the water, the combination can stand on the water bottom with the claws downward and the central body upward, relying on the gravity and the water resistance.

[0043] When the claw-shaped bait protection structure is combined with the opening and closing catching module for design and use, a jack can be arranged on the opening and closing cage net body for direct plug-in installation. The claw tip direction of the claw of the claw-shaped bait protection structure can be vertically downward or bent toward the horizontal. In this case, the direction of the jack corresponds to the claw tip direction.

[0044] The design idea of the present application comes from the author's long-term observation on the crab feeding and the experience of using the existing crab catching device. The author found that crabs like to hold food and eat it, specifically, two claws hold the food together, and directly gnaw with the mouth, or one claw holds the food to fix the food, and the other claw clamps a piece of food from the food and puts it into the mouth to eat. Under this eating method, the crab can eat the food without changing the position of the food and without moving the food. In many cases, the crab walks away after eating. There are also cases where the crab finds food and drags the food to run, but only a small part.

[0045] The author refers to the trigger principle of the existing automatic machine catching device, such as a mouse clamp, and designs a trigger for crab catching, which is not ideal. The reason should be due to the commonality of this trigger principle, which can directly touch the food and directly eat the food.

[0046] If a structure is designed to place food in it, the crab can find the food and contact the food through the designed opening path channel, but cannot normally eat the food. If the crab wants to eat the food normally, it must take the food out of the structure through the designed opening path channel. This will force the crab to pull and drag the food, and the crab should exert a lot of force when pulling and dragging the food. Therefore, the food can produce a larger displacement, and further produce a clear signal, which can be used for more device design and trigger larger design space. According to this idea, a series of devices such as food protection structure are designed, and the experimental results are completely consistent with the design idea.

[0047] The beneficial effects of the present application are: 1. A mechanical trigger of the present application, the force exerted by the target crab to overcome the block before obtaining the food, or the force exerted by the crab after obtaining the food through the food taking opening, is relatively large, which can output strong force and clear signal.

[0048] 2. An automatic machine catching device of the present application, the mechanical trigger is triggered by the target crab, which will immediately trigger the switch module to open, and then the power module drives the catching module. The crab can be caught before the crab eats the food, and the catching efficiency is high. At the same time, the power module will trigger the main line to send a clear signal to the crab catcher in time. After the crab is trapped, it is basically impossible to escape. Even if the fisherman does not timely retract the catching device, the crab will not be lost, and the catching effect is reliable. Since the catching module is triggered to catch the crab before the crab puts the food into the mouth to eat, the food is difficult to be eaten by the crab, and one bait can catch multiple crabs, and the bait utilization rate is high.

[0049] 3. An opening and closing structure catching device of the present application, which changes the traditional opening and closing structure catching device and solves the problem of no signal or small signal force.

[0050] 4. The rope sleeve catching device of the present application changes the problem that the traditional rope sleeve catching device cannot obtain the crab feeding signal in time.

[0051] 5. The claw sleeve structure catching device of the present application is a new type of crab catching device, which makes the crab enter the rope sleeve 100%, changes the problem that whether the crab enters the sleeve depends on probability in the traditional rope sleeve catching device.

[0052] 6. The present application improves the existing aquatic catching device technology, enriches the aquatic catching device market, changes the traditional crab catching method, improves the crab catching efficiency, and increases the crab catching fun.

[0053] The mechanical trigger and the catching device of the present application are mainly described by taking crabs as an example, which are not only suitable for crab catching, but also suitable for lobster, sea eel and the like, and can greatly enrich the aquatic catching device market.
