Description

Switch trigger and its alarm system and capturing device TECHNICAL FIELD

[0001] The present application relates to the field of aquatic capturing tools, in particular to a switch trigger, and an alarm system and a capturing device designed based on the switch trigger. BACKGROUND

[0002] There are various crab capturing devices on the market, all of which place bait in the device to attract crabs for capturing. However, when the crabs eat the bait, they cannot basically 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 with the patent number CN 213486499 U, “Crab fishing tackle”, the inventor writes in the patent about the part of crabs 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 capturing device using a hoop (rope sleeve), whether the crab enters the sleeve is a probability problem.

[0004] The Chinese patent with the patent number CN 216853498 U, “Novel crab capturing cage”, the inventor writes in the patent about the part of crabs eating bait: “When the crab climbs onto the stainless steel wire 12 to eat bait, hold the nylon fishing line 14 and lift it upwards”. The patent does not mention how the crab catcher knows that the crab is eating bait.

[0005] The Chinese patent with the patent number CN 214257682 U, “Connection body of float rod and bait hook and fishing tackle with the connection body”, the inventor writes in the patent about the part of crabs eating bait: “When fish, shrimp, crabs 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, and the fishing line connected with the net collecting line and the float on the fishing line also moves on the water surface. At this time, the angler lifts the fishing rod”. The patent specially designs a device for capturing the signal of crabs eating bait, but the author finds after actually using the patent fishing tackle that in the case of wind and waves, especially in the sea, the signal of crabs eating bait cannot be basically obtained. SUMMARY

[0006] The technical problem to be solved by the present application is to design a switch trigger that can respond sensitively and acquire crab feeding signals in time, and to design a switch trigger alarm system based on the switch trigger, and to upgrade the traditional catching device, and to design a new type of catching device.

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

[0008] A switch trigger comprises a conductive tube, a conductive rod and a connecting piece; at least one of the three components of the conductive tube, the conductive rod and the connecting piece is elastic; the conductive tube is connected with the connecting piece; the conductive rod is connected with the connecting piece; the conductive rod is partially or entirely located inside the conductive tube; in a natural state, the conductive parts of the conductive tube and the conductive rod are not in contact and not conductive; under external force, the elastic component of the three components of the conductive tube, the conductive rod and the connecting piece deforms, the conductive tube and the conductive rod move relatively and the conductive parts of the two are in contact and conductive, and after the external force disappears, the elastic component deforms and restores, and the conductive parts of the conductive tube and the conductive rod return to the natural state of not being in contact and not being conductive.

[0009] The aforementioned conductive tube can be a metal tube, such as an aluminum tube or a copper tube; it can also be a composite tube, such as a metal tube wrapped with an insulating layer, a metal ring is sleeved at the contact position of the designed plastic tube and the conductive rod; it can also be a spring with a relatively dense ring spacing, and the spring can be wrapped with an elastic insulating layer on the outside.

[0010] The aforementioned conductive rod can be hollow or solid; it can be a metal rod, such as a stainless steel rod, a copper rod or an aluminum rod; it can also be a composite rod, such as a plastic rod wrapped with a conductive layer, a metal ring is sleeved at the contact position of the designed plastic rod and the conductive tube; it can also be a spring with a relatively dense ring spacing, and the spring can be sleeved with an elastic support insulating rod on the inside; one end of the conductive rod can be designed into a shape that can hook objects, such as a fishhook shape or a barb shape; the conductive rod can also be composed of a conductive metal rod and an insulating plastic rod column and an external connecting component in sequence, which is called a combined rod, the external connecting component of the combined rod can be a hook or a fork; the combined rod without an external connecting component can also be used; when the combined rod is used, the connecting position of the conductive rod and the connecting piece is at the insulating plastic rod column, the metal rod of the conductive rod is separated from the external connecting component and not connected, and the metal rod part of the combined rod extends into the inside of the conductive tube.

[0011] The aforementioned connecting piece can be conductive, in which case at least one of the conductive rod and the connecting piece and the conductive tube and the connecting piece is insulating and non-conductive, ensuring that the switch trigger is not conductive in a natural state; it can also be insulating, in which case it can be an elastic rubber tube, a silica gel tube or a latex tube, or a plastic tube without elasticity, or a combination of two or more insulating material tubes; the connecting piece can also have a sealing function, allowing the switch trigger to be used underwater.

[0012] When the connecting piece is a sealing insulation elastic cylinder, the sealing insulation elastic cylinder can be integrally formed, or can be made in sections, and then combined for use. It can be made of latex, silicone, rubber, or other materials, or made in cooperation with plastic. The sealing property of the sealing insulation elastic cylinder is mainly the sealing property at the joint between the cable sleeve and the outer part of the conductive rod conductive tube. The elastic property of the material of the sealing insulation elastic cylinder can be used to tighten the joint. Sealant can be applied at the joint. A heat shrink tube can be used at the joint. A clamp can be used to tighten the joint. A screw can be used to tighten the joint, and the like. The sealing insulation elastic cylinder is filled with insulation, such as high-purity water, oil, inert gas, and air.

[0013] The aforementioned switch trigger made of the conductive tube and the conductive rod is mainly suitable for external force acting in the direction perpendicular to the axial force of the conductive tube or the conductive rod. Another type of combination of the conductive tube and the conductive rod with special structure is suitable for external force acting in any direction.

[0014] In this type of combination of the conductive tube and the conductive rod with special structure, the part of the conductive rod inside the conductive tube is also provided with a conductive ring thicker than the adjacent conductive rod, which is tightly connected with the conductive rod, and can be sleeved or welded. The two ends of the conductive ring inside the conductive tube are tightly connected with a conductive ring segment, which can be sleeved or welded. The middle part of the conductive ring segment has a hole for the conductive rod to pass through. In the natural state, the conductive ring segment does not contact and conduct with the conductive ring of the conductive rod. Under the action of external force, the conductive ring segment and the conductive ring of the conductive rod move relatively to contact and conduct. After the external force disappears, the conductive ring segment and the conductive rod and the conductive ring return to the state of not contacting and conducting.

[0015] The aforementioned several types of conductive tubes, several types of conductive rods, and several types of connecting pieces can be combined in many ways to realize the switch trigger.

[0016] A sealed switch trigger is based on the switch trigger described above. The conductive tube is a metal tube. The conductive rod is a metal rod or a combined rod. The connecting piece is a sealing insulation elastic cylinder. The conductive tube is sleeved in the sealing insulation elastic cylinder. The conductive rod and one end of the sealing insulation elastic cylinder are sleeved. One end of the conductive rod extends into the inside of the conductive tube, and the other end extends out of the sealing insulation elastic cylinder. The sealing insulation elastic cylinder is filled with insulation.

[0017] A sealed switch trigger with a bait protection structure, based on the sealed switch trigger described above, further comprising a bait protection structure, the bait protection structure and the switch trigger are assembled together; the bait protection structure can be fixed relative to the conductive tube, the part of the conductive rod that extends out of the sealed insulating elastic cylinder is located in the bait protection structure, and the conductive rod can move relative to the bait protection structure under external force. Alternatively, the bait protection structure can be fixed relative to the conductive rod, and the conductive tube is located in the bait protection structure, and the conductive tube can move relative to the bait protection structure under external force. Alternatively, the end of the switch trigger that can move relative to the bait protection structure is located near the bait opening, blocking the target crab from contacting the bait inside the bait protection structure through the bait opening, forcing the target crab to trigger the switch trigger before it touches the bait.

[0018] The aforementioned bait protection structure comes from another patent called "Mechanical trigger and its trapping device", which refers to an obstacle between the bait and the target crab, preventing the target crab from directly contacting the bait placed in the bait protection structure. The so-called target crab cannot directly contact the bait placed in the bait protection structure means that the target crab must overcome the obstacle or bypass the obstacle before it can touch the bait. This is in contrast to the target crab being able to directly contact the bait, which means that there is no obstacle between the target crab and the bait, and the target crab can approach the bait directly without any obstruction.

[0019] The bait protection structure can have various shapes, such as a spherical cage, a square cage, a pyramid-shaped cage, or a box with an opening. One of the main functions of the bait protection structure is to force the crab to exert more force to eat the bait.

[0020] The aforementioned bait opening is an opening provided on the bait protection structure, which is a channel for the target crab to access the bait inside the bait protection structure.

[0021] Methods to change the sensitivity of the switch trigger include: changing the elasticity of the elastic component, such as changing the softness and reducing the size; reducing the contact distance between the conductive rod and the conductive tube; lengthening the length of the conductive rod or the conductive tube that moves after being stressed; and so on.

[0022] A switch trigger alarm system, comprising a sealed switch trigger as described above, a cable, a power source, and an alarm; one end of the cable is connected to the sealed insulating elastic cylinder, and the two wire ends are connected to the conductive tube and the conductive rod, respectively; the other end of the cable is connected between the power source and the alarm, and the power source and the alarm are connected;

[0023] A switch trigger alarm system with protective bait structure, comprising a sealed switch trigger with protective bait structure as described above, a cable, a power supply, and an alarm; one end of the cable is connected to the sealed insulating elastic sleeve, and the two wire ends are connected to the conductive tube and the conductive rod, respectively; the other end of the cable is connected between the power supply and the alarm, and the power supply and the alarm are connected;

[0024] The aforementioned alarm is a device that can emit signals that humans can perceive, such as sound, vibration, light, smell, high temperature, low temperature, and radiation. The aforementioned power supply includes a button cell, a dry battery, and a storage battery. The aforementioned cable includes a wire, a video line, and a signal line.

[0025] A switch trigger alarm system with protective bait structure, comprising a sealed switch trigger with protective bait structure as described above, a cable, a power supply, and an alarm; one end of the cable is connected to the sealed insulating elastic sleeve, and the two wire ends are connected to the conductive tube and the conductive rod, respectively; the other end of the cable is connected between the power supply and the alarm, and the power supply and the alarm are connected;

[0026] The opening and closing capture module is automatically opened by the elastic force of the elastic component, and some also rely on the gravity of the component or only rely on the gravity of the component. Under the action of external force, the external force overcomes the resistance of the force that opens it, and the capture module is closed. The elastic module is generally a spring, but it can also be a rubber band, a glass fiber strip, etc. The function of the cable assembly is to bundle the pull rope together to change the direction of the pull force of the pull rope, so that the opening and closing cage net body can be closed tightly.

[0027] The cable assembly and the switch trigger of the switch trigger alarm system are installed on the opening and closing cage net body. When using the switch trigger alarm system as described above, the switch trigger can be installed on the opening and closing cage net body, and the cable assembly can be installed on the switch trigger or the opening and closing cage net body. The cable assembly can also be installed on the opening and closing cage net body, and the switch trigger can be installed on the cable assembly. When using the switch trigger alarm system with protective bait structure as described above, the protective bait structure can be installed on the opening and closing cage net body, and the cable assembly can be installed on the protective bait structure or the opening and closing cage net body or the switch trigger. The cable assembly can also be installed on the opening and closing cage net body, and the protective bait structure can be installed on the cable assembly.

[0028] The opening and closing capture module is derived from the commonly used opening and closing capture device in the prior art.

[0029] The four kinds of open-close capture devices currently in use are mainly: spherical open-close cages, mainly from Korean patent "Capture Structure for Fresh water Crab Fish" with application number KR2020090012433U and Chinese patent "A new type of crab capture cage" with patent number CN 216853498 U; tower-shaped open-close cages, mainly from US patent "CRAB-TRAP" with application number US19080433438A, US patent "KNOCKDOWN CRAB-TRAP" with application number US19120721223A and US patent "CRAB-TRAP" with application number US19150058374A; square open-close cages, mainly from US patent "Crab trap" with application number US19230613774A and US patent "Crab trap" with application number US19230652247A; net clamps, mainly from British patent "CLAPTRAP" with application number GB8332188A and US patent "Book net for crabs, lobsters, and the like" with application number US19770762039A, which mainly includes open-close cage net body, elastic component, bait hanging component, line collecting component, pull rope, five parts, and the bait hanging component and line collecting component are usually integrated together, and the line collecting component of the square open-close cage is sometimes the open-close cage net body itself. The open-close structure capture device described in the present invention is basically obtained by replacing the bait hanging component in the invention with the alarm system.

[0030] A rope sleeve capture device, comprising a switch trigger alarm system or a switch trigger alarm system with bait protection structure as described above, a rope sleeve base and a rope sleeve; the rope sleeve is connected to the rope sleeve base; when using a switch trigger alarm system, the switch trigger is installed on the rope sleeve base; when using a switch trigger alarm system with bait protection structure, the bait protection structure and the rope sleeve base are combined together.

[0031] 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, which becomes tighter after trapping the object, and the rope can be fishing line or steel wire.

[0032] 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; can be a 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; can be a circular perforated metal sheet, such as the circular flat plate used in the Chinese patent "Network cable buckle and crab fishing tool" with application number CN202122440123.5; and can also be a support made of wire, such as the support legs and framework used in the patent "Crab fishing tool" with authorization number CN213486499U.

[0033] The bait protection structure and the rope sleeve base are combined together, which can be connected together, at which time the bait protection structure and the rope sleeve base are two physical entities; or can be combined into a functional combination, which has the functions of both the bait protection structure and the rope sleeve base, at which time the bait protection structure and the rope sleeve base are not physically divided, but conceptually divided by function, or can be said that the bait protection structure has the function of the rope sleeve base.

[0034] A claw sleeve structure catching device, comprising a switch trigger alarm system, a claw-shaped bait protection structure, a bait taking opening, a wire management component, and a rope sleeve; the claw-shaped bait protection structure comprises a central body and two claws, the claws are distributed around the central body, and there are at least three claws; the switch trigger of the switch trigger alarm system is installed on the claw-shaped bait protection structure, the part of the conductive rod that extends out of the sealed insulating elastic cylinder is located inside the claw-shaped bait protection structure, the bait taking opening is located on the claw-shaped bait protection structure, the wire management component is arranged on the claws, and the rope sleeve is connected to the claw-shaped bait protection structure and can be unfolded around the bait taking opening under the action of the wire management component.

[0035] The claw-shaped bait protection structure is shaped like an open claw and also shaped like a bacteriophage. The claws can be made of wire, such as copper wire or steel wire; at this time, the central body can be formed by winding or welding the claws at one end together or winding them together; it can also be a section of iron pipe with the claws welded at one end; it can also be a perforated plastic part with the claws inserted into the holes of the plastic part; the claws can also be made of plastic, and the claws and the central body can be integrally formed by injection molding.

[0036] The bait taking opening is formed between adjacent claws and the ground surface after the claw-shaped bait protection structure stands on the ground surface.

[0037] The wire arranging component can be a plastic clip, which is distributed on the claw; can be a plastic strip with a clip groove, which is sleeved on the claw; or can be a clip groove on the claw, which is integrated with the claw. The plastic can be hard plastic, soft plastic, silicone, latex or rubber. The wire arranging component can embed the rope in the clip or clip groove, which is not easy to fall out when throwing or being impacted by water flow. However, the rope can easily fall out when the rope sleeve is hung by an external object. The rope sleeve is unfolded around the bait opening, and the movable buckle of the rope sleeve is distributed around the bait opening, which is roughly coincident with the boundary of the bait opening.

[0038] For the claw sleeve structure catching device, a lead weight can be added. The position of the lead weight is arranged to ensure that the gravity center of the combination of the claw-shaped bait protection structure, the wire arranging component, the rope sleeve and the switch trigger is deviated from the upper part where the central body is located to the lower part of the combination, so that the combination can stand on the water bottom with the claw downward and the central body upward under the action of gravity and water resistance after entering the water.

[0039] When the claw-shaped bait protection structure and the opening and closing catching module are combined and used, 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-shaped bait protection structure can be vertically downward or bent toward the horizontal. In this case, the jack direction is arranged corresponding to the claw tip direction.

[0040] An anchor device includes the switch trigger alarm system described above and an anchor hook. The switch trigger of the switch trigger alarm system is combined with the anchor hook.

[0041] The combination of the switch trigger and the anchor hook can be that the switch trigger is installed on the anchor hook or that the switch trigger is indirectly connected with the anchor hook through a fishing line or a wire.

[0042] A net bag structure catching device includes the switch trigger alarm system described above or the switch trigger alarm system with a bait protection structure and a net bag. When the switch trigger alarm system is used, the switch trigger is installed on the net bag. When the switch trigger alarm system with a bait protection structure is used, the switch trigger is installed on the net bag or placed in the net bag.

[0043] The net has an opening, the net is recessed on the side of the opening, the opening is generally made of iron wire, the iron wire is inserted into the mesh of the opening to support the opening, for example, the ring net used in US20030374188A Pocketed Hoop Net, the switch trigger is installed on the iron wire, the switch trigger with the bait protection structure can be installed on the iron wire or directly placed in the net, the bait is worn on the conductive rod during use, then the device is thrown into the water, the crab finds the bait and eats the bait to trigger the switch trigger alarm system to alarm, and the net is lifted to hold the crab.

[0044] Based on the switch trigger and the switch trigger alarm system described above, more existing capture devices can be upgraded, and more new capture devices can be designed.

[0045] When the above-mentioned devices are manufactured and used, connection such as socket connection and plug connection is involved, in order to increase the connection strength, thread can be arranged at the connection, adhesive can be increased, a hoop can be additionally arranged, a heat shrink tube can be used, and other conventional methods can be used to increase the connection strength and sealing performance.

[0046] In order to avoid that the connection between the cable and the switch trigger is disconnected during use, a cable can be connected to the part of the cable away from the switch trigger.

[0047] The design idea of the present application comes from the author's long-term observation of the crab eating bait and the use experience of the existing crab catching device. The author found that the crab likes to hold the bait and gnaw, specifically, two claws hold the bait together, directly gnaw with the mouth, or one claw holds the bait to fix the bait, and the other claw clamps a piece of bait from the bait and puts it into the mouth to eat. Under this eating method, the crab can eat the bait without changing the position of the bait and moving the bait. In other words, during the normal eating process of the crab, the displacement of the bait is very small. If a device can be designed to sense a very small force, and after the bait is placed, the crab touches the bait to cause a very small displacement of the bait, which can be sensed and converted into an obvious signal that can be sensed by humans, and is not affected by wind and waves, it will be very valuable, so the present application is produced.

[0048] The present application mainly takes crabs as an example to illustrate the content of the application, in fact, the present application is also applicable to the capture of lobsters, sea eels, fish, chickens, ducks, geese and other animals.

[0049] The capture device of the present application can improve its water flow resistance and change its center of gravity position by adding a lead sinker.

[0050] The beneficial effects of the present application are: 1. The switch trigger of the present application can be triggered under the action of slight external force, and is sensitive to external force and has a design suitable for underwater use.

[0051] 2. The switch trigger alarm system of the present application is not affected by wind and waves, and is extremely sensitive and power-saving.

[0052] 3. The existing capture device upgraded based on the switch trigger alarm system of the present application includes a kind of open-close structure capture device, a kind of rope sleeve capture device, a kind of anchor fish device, a kind of net bag structure capture device, and the prey such as crabs can trigger the switch trigger alarm system in time when eating bait, and the hunter can obtain the signal of the prey eating bait in time and catch the prey in time, which changes the problem of no signal or signal affected by wind and waves of the traditional capture device.

[0053] 4. The claw sleeve structure capture device of the present application is a new type of crab capture device, which can make crabs enter the rope sleeve with 100% probability, changes the problem that crabs enter the sleeve with a probability in the traditional rope sleeve capture device, and changes the problem that there is no timely crab bait signal in the traditional rope sleeve capture device.

[0054] 5. The present application improves the technical level of the existing aquatic capture device, enriches the aquatic capture device market, changes the traditional crab catching method, improves the crab catching efficiency, and increases the crab catching fun. BRIEF DESCRIPTION OF DRAWINGS
