Description

Technical Field

[0001] This utility model belongs to the field of fishing gear technology, specifically relating to an automatic bottom-finding fishing device. Background Technology

[0002] Existing automatic bottom-finding devices for fishing tackle mainly include timed line locking and double-lead sliding float fishing. Timed line locking devices control the locking time between the fishing line and the bottom-finding device through a built-in timer or delay mechanism. After the device is cast, the timer starts, and it automatically locks after the preset time. Double-lead sliding float fishing involves passing a fishing line through a lead weight, then a float, and finally another lead weight. When the first lead weight reaches the bottom, the float floats on the surface. Tightening the fishing line causes the second lead weight to press down on the line, making the float stand upright, thus achieving automatic bottom finding. However, both of these automatic bottom-finding devices suffer from problems such as unclear float movement, cumbersome operation, and sometimes failure to tighten the fishing line between the bottom and the bottom-finding device, failing to meet the needs of anglers in practical use. Utility Model Content

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example:

[0026] like Figures 1 to 5 As shown, this utility model embodiment provides an automatic bottom-finding fishing device, including a cylindrical shell 1, a fishing line 2, and a crossbar 3. The two ends of the fishing line 2 pass through holes 101 at the center of both ends of the cylindrical shell 1, and the fishing line 2 extending out of the front end of the cylindrical shell 1 is connected to a hook 201 and a sinker 202. The front end of the cylindrical shell 1 is provided with a front hole 102, the top front hole 103 and a float 4 are provided at the front position of the top of the cylindrical shell 1, the bottom front hole 104 is provided at the front position of the bottom of the cylindrical shell 1, and the top rear hole 105 is provided at the rear position of the top of the cylindrical shell 1. A magnet 5 is provided on the fishing line 2 inside the cylindrical shell 1, and a magnet 6 is provided at the rear end of the cylindrical shell 1. The fishing line 2 passes through the magnet 6. The crossbar 3 is horizontally arranged at the rear position inside the cylindrical shell 1, and the height of the crossbar 3 is higher than the height of the holes 101.

[0027] In this embodiment of the invention, a hook 201 and a sinker 202 are attached to one end of the fishing line 2. The other end passes through the hole 101 at the front end of the cylindrical outer shell 1, goes over the crossbar 3 inside the cylindrical outer shell 1, and then exits through the hole 101 at the rear end of the cylindrical outer shell 1. The hole 101 has a large diameter, allowing the fishing line to pass through freely. The top front end of the cylindrical outer shell 1 is provided with a front top hole 103 and a float 4, the top rear end is provided with a rear top hole 105, and the bottom of the cylindrical outer shell 1 is provided with a bottom hole 104. A magnet 5 is installed on the fishing line 2 inside the cylindrical shell 1, and a magnet 6 is installed at the rear end of the cylindrical shell 1. The magnets 5 and 6 attract each other and clamp the fishing line 2 in the middle when they are attracted together, thus fixing the fishing line 2. The buoyancy generated by the float 4 set at the top of the cylindrical shell 1 is greater than the weight of the cylindrical shell 1 and the sinker 202. The float 4 can sink, rise, or move horizontally after a fish bites the hook, alerting the angler and prompting him to react. The overall structure of the device is simple, easy to operate, and increases the angler's fishing efficiency.

[0028] In one feasible implementation scheme, such as Figure 1As shown, a stopper 203 is provided on the fishing line 2 between the fishhook 201 and the sinker 202. By providing the stopper 203 between the sinker 202 and the fishhook 201, the fishhook 201 and the sinker 202 are separated, restricting the sinker 202 from sliding toward the fishhook 201, so as to adjust the distance between the fishhook 201 and the sinker 202.

[0029] In one feasible implementation scheme, such as Figure 2 and Figure 3 As shown, a protrusion 7 is provided at the rear end of the cylindrical outer shell 1, and the second magnet 6 is disposed inside the protrusion 7. By placing the second magnet 6 inside the protrusion 7, it can generate an attractive force on the first magnet 5. When the second magnet 6 and the first magnet 5 are attracted together, the fishing line 2 will be clamped in the middle, thereby fixing the fishing line 2.

[0030] In one feasible implementation scheme, such as Figure 1 As shown, the front-end drain hole 102 is fan-shaped and distributed in a ring around the front-end hole 101. By setting the fan-shaped front-end drain hole 102 around the hole 101, the water inside the device can be quickly drained when the device is lifted.

[0031] In one feasible implementation scheme, such as Figure 1 As shown, the diameter of the rear top drain hole 105 is smaller than the diameter of the front top drain hole 103. By setting the diameter of the rear top drain hole 105 to a smaller diameter, when the device is thrown into water, the rear top drain hole 105 can slowly expel air, and the rear end of the device is higher than the front end, ensuring the normal operation of the device.

[0032] In one feasible implementation scheme, such as Figure 1 As shown, the bottom drain hole 104 is located at the bottom of the cylindrical outer shell 1, near the front third. By setting the bottom drain hole 104, after the device is immersed in water, it works in conjunction with the top front drain hole 103 and the top rear drain hole 105 to allow the front end of the device to sink into the water first, thereby enabling the device to operate normally according to the working sequence.

[0033] In one feasible implementation scheme, such as Figure 1 and Figure 5 As shown, the crossbar 3 is positioned on the side wall of the cylindrical outer shell 1 at a distance of one-third from the top of the cylindrical outer shell 1. By fixing the crossbar 3 at a distance of one-third from the top of the cylindrical outer shell 1, the magnet 5 on the fishing line 2 cannot pass over the crossbar 3, but can only pass under the crossbar 3.

[0034] In one feasible implementation scheme, such as Figures 1 to 4As shown, a float seat 401 is fixedly connected to the bottom of the float 4. The float seat 401 is provided with a connecting ring 402, which is located on the cylindrical outer shell 1 between the two front top holes 103 and is movably connected to the cylindrical outer shell 1. By setting the float seat 401 at the bottom of the float 4 and the connecting ring 402 at the bottom of the float seat 401 being movably connected to the top of the cylindrical outer shell 1, the buoyancy generated by the float 4 prevents the device from completely sinking into the water, but keeps it suspended at a specified water depth. When the float 4 is set at the top of the cylindrical outer shell 1 near the front end, the front end will be higher than the rear end when the device is completely submerged in water, thus allowing the device to operate normally.

[0035] In the specific implementation of the automatic bottom-finding fishing device provided in this embodiment, when the entire device is thrown, magnet 5 will adhere tightly to the front end of the cylindrical shell 1 under the action of inertia, and will not be attracted to magnet 6 at the rear end of the cylindrical shell 1, thus not fixing the fishing line 2. When the sinker 202 enters the water, it will drive the front end of the cylindrical shell 1 to enter the water first. Water enters the interior of the cylindrical shell 1 through the bottom hole 104, the top front hole 103, and the front hole 101. When the water has submerged the top front hole 103, air can only be discharged through the top rear hole 105 and the rear hole 101, because the top... The small diameter of the rear drain hole 105 restricts air from being completely expelled from the cylindrical outer shell 1 for about two seconds, preventing the cylindrical outer shell 1 from sinking too deeply due to inertia. During this period, the rear end of the cylindrical outer shell 1 remains higher than the front end. The trapped air is finally expelled from the rear drain hole 105. Simultaneously, the weight 202 pulls the front end of the cylindrical outer shell 1 downwards, while the slower air expulsion from the rear drain hole 105 causes the rear end of the cylindrical outer shell 1 to rise. This prevents the front end of the cylindrical outer shell 1 from being higher than the rear end, which would cause magnet 5 to slide to the rear end of the cylindrical outer shell 1 immediately after being thrown into the water and attract magnet 6. When the sinker 202 reaches the bottom, the tension exerted by the sinker 202 on the front end of the cylindrical shell 1 through the fishing line 2 disappears. The buoyancy generated by the float 4 is greater than the weight of the device itself, causing the front end of the cylindrical shell 1 to rise, making it higher than the rear end. At this time, magnet 5 will slide towards the rear end of the cylindrical shell 1 and finally attract to magnet 6, clamping the fishing line 2 in the middle and fixing it in place. Because the fishing line 2 passes over the crossbar 3, pulling the fishing line 2 after a fish bites will cause the cylindrical shell 1 to sink, which in turn will cause the float to move. 4. Swinging: When the hook 201 pierces the fish's mouth, the fishing line 2 is pulled, causing the rear end of the cylindrical shell 1 to be higher than the front end. Because the fishing line 2 is clamped in the middle by magnet 5 and magnet 6 after passing over the crossbar 3, when the clamped fishing line 2 is pulled forcefully, the weight of the sinker 202 will cause magnet 5 and magnet 6 to separate, allowing magnet 5 to return to the front end of the cylindrical shell 1. The fishing line 2 can then move freely inside the cylindrical shell 1 again, making it convenient for the next use. The overall structure of the device is simple and easy to operate. The float 4 reacts quickly after the fish bites the hook, and the angler can react in time after observing the up and down movement of the float 4.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
