Description

Technical Field

[0001] This utility model belongs to the field of fishing equipment and relates to an automatic sealing type fishing device. Background Technology

[0002] Traditional fish traps have a fish inlet at the lower part of the side wall. This inlet is made of a flexible mesh that tapers from the outside in. This makes it impossible for fish and crabs to get out once they enter. However, this method results in a small fish inlet, making it difficult and time-consuming for fish and crabs to enter the trap, thus reducing fishing efficiency. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides an automatic sealing fish catcher. This device has the advantage that the fish inlet is open when the fish is being baited, allowing fish and crabs to enter, and automatically closes the fish inlet after a period of time.

[0004] The objective of this invention is achieved as follows:

[0005] An automatic sealing type fish catcher includes a fish cage with an opening at one end. A fixed plate is provided at the opening, and a fish inlet is provided on the fixed plate. A sealing plate is rotatably connected to the fixed plate, and a limiting groove is provided on the sealing plate. A feed clamp is also connected to the fixed plate. The feed clamp includes two clamping plates. One end of the two clamping plates is a fixed end connected to the fixed plate, and the other end of the two clamping plates is a limiting end. The two clamping plates at the limiting end have an elastic force that clamps each other. The limiting end passes through the limiting groove of the sealing plate and clamps a solid soluble substance. The solid soluble substance opens the two clamping plates and jams the limiting groove. An elastic element is also connected to the fixed plate. The other end of the elastic element is connected to the sealing plate and always provides a force to rotate the sealing plate in the direction of the fish inlet.

[0006] When the solid soluble substance spreads the two clips apart and locks the limiting groove, the fish inlet is in an open state; when the solid soluble substance dissolves, the two clips clamp together and move closer to each other, releasing the restriction on the limiting groove. Under the action of the elastic element, the sealing plate rotates toward the fish inlet and blocks the fish inlet to complete the sealing.

[0007] With the above settings, when the fish inlet is open, fish and crabs can easily enter the fish trap without hindrance. When the solid soluble substance melts, the sealing plate automatically reseals the fish inlet, preventing fish and crabs from escaping the fish trap. Furthermore, by controlling the amount of solid soluble substance, the automatic sealing time can be controlled.

[0008] The present invention is further configured such that the solid soluble substance is rock sugar, milk tablets, soap, or soluble plastic.

[0009] Solid soluble substances can be very diverse and can be used in many everyday items, making them low-cost and readily available.

[0010] The present invention is further configured such that the soluble plastic is a polyvinyl alcohol soluble plastic.

[0011] The present invention is further configured such that: the fixing plate is also provided with a guide post, the guide post is provided with a guide groove, and the sealing plate is slidably disposed in the guide groove.

[0012] The above settings make the rotation of the sealing plate more stable, stabilize its movement, and ensure that the sealing plate can reliably seal the fish's mouth.

[0013] The present invention is further configured such that: the elastic element is a spring or a rubber band, one end of the spring or rubber band is fixed on the guide post, and the other end is fixed on the sealing plate, and the spring or rubber band always provides a force to the sealing plate to rotate in the direction of the fish inlet.

[0014] The present invention is further configured such that: one end of the guide groove is open and the other end is a positioning end; when the sealing plate abuts against the positioning end, the sealing plate seals the fish inlet.

[0015] By setting the positioning end, the sealing plate can accurately seal the fish's mouth.

[0016] The present invention is further configured such that: the elastic element is a torsion spring, the fixing plate is provided with a first torsion spring fixing end, the sealing plate is provided with a second torsion spring fixing end, one end of the torsion spring abuts against the first torsion spring fixing part, the other end of the torsion spring abuts against the second torsion spring fixing end, and the torsion spring always applies a force to the sealing plate to rotate in the direction of the fish inlet.

[0017] The present invention is further configured such that the fish cage includes a cage frame and a fishing net, the cage frame being composed of an elastic body in a spiral coil.

[0018] The present invention is further configured such that: the limiting groove is formed by a fixed plate, two side walls and a crossbeam, the distance from the crossbeam to the fixed plate is less than the thickness when the limiting ends of the two clamping pieces are spread apart by a solid soluble substance, and the distance from the crossbeam to the fixed plate is greater than the thickness after the limiting ends of the two clamping pieces are clamped.

[0019] The outstanding and beneficial technical effects of this invention compared to the prior art are: when the fish inlet is open, fish and crabs can easily enter the fish trap without hindrance; when the solid soluble substance melts, the sealing plate automatically reseals the fish inlet, preventing fish and crabs from escaping the fish trap; and by controlling the amount of solid soluble substance, the automatic sealing time can be controlled.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0026] An automatic sealing type fish catcher includes a fish cage 1 with an opening at one end. A fixing plate 2 is provided at the opening, and a fish inlet 3 is provided on the fixing plate 2. A sealing plate 4 is rotatably connected to the fixing plate 2, and a limiting groove 5 is provided on the sealing plate 4. A clamping device 6 is also connected to the fixing plate 2. The clamping device 6 includes two clamping pieces 7. One end of the two clamping pieces 7 is a fixed end 8, which is connected to the fixing plate 2. The other end of the two clamping pieces 7 is a limiting end 9. The two clamping pieces of the limiting end 9 have an elastic force that clamps each other. The limiting end 9 passes through the limiting groove 5 of the sealing plate and clamps a solid soluble substance 10. The solid soluble substance opens the two clamping pieces 7 and jams the limiting groove 5. An elastic element 11 is also connected to the fixing plate 2. The other end of the elastic element 11 is connected to the sealing plate 4 and always provides a force to rotate the sealing plate 4 in the direction of the fish inlet 3.

[0027] When the solid soluble substance 10 spreads the two clips 7 apart and jams the limiting groove 5, the fish inlet 3 is in an open state; when the solid soluble substance 10 dissolves, the two clips 7 clamp together and move closer to each other, releasing the restriction on the limiting groove 5. Under the action of the elastic element 10, the sealing plate 4 rotates toward the fish inlet 3 and blocks the fish inlet 3 to complete the sealing.

[0028] With the above settings, when the fish inlet 3 is open, fish and crabs can easily enter the fish trap without obstruction. Once the solid soluble substance 10 dissolves, the sealing plate 4 automatically reseals the fish inlet 3, preventing fish and crabs from escaping. Furthermore, by controlling the amount of solid soluble substance 10, the automatic sealing time can be controlled. Preferably, to improve the fishing effect, the attractant should vary depending on the type of fish, meaning the attractant food should be changed according to the fish's preferences. Additionally, the attractant food should be placed in a closed space, such as a perforated transparent plastic box, so the fish can only see and smell it, and their mouths can touch it but not eat it, ensuring the "timed attractant trap" doesn't run out of food and fail to catch fish. Furthermore, the attractant trap should be made as long and large as possible, with multiple places inside to make the fish feel safer and more comfortable, thus catching a sufficient number of fish.

[0029] The solid soluble substance 10 is a general concept. Solid soluble substances can be of various kinds, and many items in daily life can be used, such as rock candy, milk tablets, salt blocks, soap, or soluble plastics, etc. Therefore, solid soluble substances are not limited to those mentioned above. Anything that is solid in the air, can open the two clamping post limiting grooves, and can dissolve in water after a period of time belongs to the solid soluble substances described in this application.

[0030] The soluble plastic is a polyvinyl alcohol soluble plastic.

[0031] The fixed plate 2 is also provided with a guide post 12, and the guide post 12 is provided with a guide groove 13. The sealing plate 4 is slidably disposed in the guide groove 13. Through the above arrangement, the rotation of the sealing plate 4 is more stable, the path of the sealing plate 4 is stabilized, and the sealing plate 4 can stably seal the fish inlet 3.

[0032] The spring element 11 is also a broader concept, and it can be a variety of elastic restoring structures formed by springs, rubber bands, and torsion springs. Three examples are given below:

[0033] The elastic element 11 is a spring or rubber band. One end of the spring or rubber band is fixed to the guide post 12, and the other end is fixed to the sealing plate 4. The spring or rubber band always exerts a force on the sealing plate 4 to rotate in the direction of the fish inlet 3.

[0034] The elastic element 11 is a torsion spring. The fixing plate is provided with a first torsion spring fixing end, and the sealing plate is provided with a second torsion spring fixing end. One end of the torsion spring abuts against the first torsion spring fixing part, and the other end of the torsion spring abuts against the second torsion spring fixing end. The torsion spring always applies a force to the sealing plate to rotate in the direction of the fish inlet.

[0035] The guide groove 13 is open at one end and positioned at the other end 14. When the sealing plate 4 abuts against the positioning end 14, the sealing plate 4 seals the fish inlet 3. The positioning end ensures that the sealing plate accurately seals the fish inlet.

[0036] The fishing cage 1 includes a cage frame 15 and a fishing net 16. The cage frame 15 is made of an elastic body that is spirally coiled.

[0037] The limiting groove 5 is formed by a fixed plate 2, two side walls 17 and a crossbeam 18. The distance between the crossbeam 18 and the fixed plate 2 is less than the thickness of the limiting ends 9 of the two clamping pieces 7 when they are spread apart by solid soluble substances. The distance between the crossbeam 18 and the fixed plate 2 is greater than the thickness of the limiting ends 9 of the two clamping pieces 7 after they are clamped.

[0038] The present invention has the feature that the fish inlet is open when the fish is in a feeding state, making it convenient for fish and crabs to enter, and automatically closes after a period of time.

[0039] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
