Lever type automatic bottom finding floating seat

Abstract

A lever type automatic bottom finding floating seat belongs to fishing gear supplies, and utilizes the lever principle to drive a counterweight sliding lead to slide correspondingly under different stress states so as to realize the process that a fishing line slides down freely to be locked. Firstly, the weight of a bottom lead weight, the weight of a counterweight sliding lead, the position of a buoy hanging point and the magnitude of buoyancy are reasonably configured, the buoy buoyancy is regarded as lever supporting force, the supporting point is located at the position of a buoy hanging ring (5), after a buoy base is thrown into water, the moment of a wire outlet side is larger than that of a wire inlet side, the buoy base is in the state in the figure 3, and the counterweight sliding lead is far away from a wire inlet hole; the wire inlet hole (3), the counterweight sliding lead (4) and a hole channel of the piston type wire outlet pipe (2) form a smooth channel, the fishing wire slides freely, and a lead weight at the bottom falls down smoothly. After the lead at the bottom falls to the ground, the downward force of the wire outlet end becomes smaller instantly, the moment of the wire outlet side is smaller than that of the wire inlet side, the floating seat is in the state shown in the figure 4, the balance weight sliding lead quickly slides to abut against the wire inlet hole, and due to the fact that the wire inlet hole (3) and a hole channel of the balance weight sliding lead (4) are mutually staggered, the fish wire is extruded and locked, and the whole bottom finding and wire locking process is completed; and the buoy acts.

Description

Technical Field

[0001] Belongs to fishing gear supplies. Background Art

[0002] During fishing, finding the bottom and adjusting the float is an important part and a relatively complicated process, especially in the wild environment. For walking anglers, it is necessary to find the bottom and adjust the float frequently. In order to save this process as much as possible, I have developed a new type of automatic bottom-finding float seat to provide anglers with another fishing experience and choice. Summary of the invention

[0003] The technical solution adopted by the utility model to solve the technical problem is as follows: the float seat is composed of a main body tube (1), a piston-type outlet tube (2), an inlet hole (3), a weighted lead (4), a float ring (5), an exhaust hole (6), and a pipe cap (7), and the overall structure is a lever with the float ring (5) as a support point. The inner wall of the main body tube (1) is smooth, leaving a certain space for the weighted lead (4) to slide freely in the tube, and ensuring that when the weighted lead (4) slides against the piston-type outlet tube (2), the passages among the inlet hole (3), the weighted lead (4), and the piston-type outlet tube (2) are unobstructed, and the fishing line can slide freely; the piston-type outlet tube (2) is fixed by the friction between the piston and the tube wall, and can be manually pushed and pulled for adjustment; the weighted lead (4) and the inlet hole (3) are mutually offset and not overlapped; the exhaust hole (6) prevents air from accumulating in the tube; the pipe cap (7) can be opened, and is provided with an exhaust hole and an inlet hole. By using the lever principle, the float seat drives the weighted lead to slide accordingly under different stress states, so that the fishing line can slide freely until it is locked. In order to achieve the above process, the weight of the bottom lead sinker, the weighted lead, the position of the float hanging point and the buoyancy must be reasonably configured. The buoyancy of the float is regarded as the lever support force, and the support point is at the float hanging ring (5). When the float seat is thrown into the water, the torque on the outgoing line side is greater than the torque on the incoming line side, and the float seat presents a Figure 3 The counterweight lead slide is away from the line inlet hole, and the line inlet hole (3), the counterweight lead slide (4), and the piston-type line outlet tube (2) form a smooth passage, the fishing line slides freely, and the bottom lead sinker falls smoothly. When the bottom lead sinker falls to the ground, the downward force on the outlet end instantly decreases, the torque on the outlet side is smaller than the torque on the inlet side, and the float seat presents Figure 4 The counterweight lead slides quickly against the line entry hole. Since the line entry hole (3) and the counterweight lead slide (4) are misaligned, the fishing line is squeezed and locked, completing the entire bottom finding and line locking process. When the fishing line at the outlet end is pulled, the float moves. After the bottom lead falls to the ground, the sum of the upward forces acting on the float seat must be greater than the sum of the downward forces acting on the float seat, ensuring that part of the float tail is exposed to the water surface so that the float movement can be observed. The float preferably uses a thick tail vertical float (the float tail must have a certain buoyancy), which is more in line with the habits of most anglers. A surface float similar to a ball float can also be used. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The main tube (1) is a main structural member, and its inner wall must be smooth, leaving a certain space for the weighted lead (4) to slide freely in the tube, and ensuring that when the weighted lead (4) slides against the piston-type outlet tube (2), the passages among the inlet hole (3), the weighted lead (4) and the piston-type outlet tube (2) are unobstructed, and the fishing line can slide freely; the piston-type outlet tube (2) is fixed by the friction between the piston and the tube wall, and the values ​​of L1 and L2 can be adjusted by manual pushing and pulling; the surface of the weighted lead (4) must be smooth and corrosion-resistant, and the passages of the inlet hole (3) should be offset and not overlapped; the exhaust hole (6) is to prevent air from accumulating in the tube; the tube cap (7) is provided with an exhaust hole and an inlet hole, and it is convenient to change the sinker and thread the line after opening.

[0011] Figure 5 The downward force of the outlet is proposed to be G1 (this force has different values ​​before and after the lead falls to the bottom), the weight of the sliding lead is G2, the upward force provided by the float is F, and the downward force of the float seat itself is G3 (excluding the sliding lead of the weight). The above force values ​​are all in the water environment, not in the air. The force arm of the downward force of the outlet is L1 (the horizontal distance from the outlet to the ring), the force arm of the sliding lead of the weight is L2 (the horizontal distance from the center of gravity of the sliding lead of the weight to the ring), and the force arm of the downward force of the float seat itself (excluding the sliding lead of the weight) is L3 (the horizontal distance from the center of gravity to the ring). DETAILED DESCRIPTION

[0012] 1. In order to reasonably configure the weight of the bottom lead sinker, the weight of the sliding lead, the position of the floating hanging point, the buoyancy, the size of the tube body and other parameters, according to Figure 5 The typical state shown is calculated and determined based on the following five conditions and debugged.

[0013] Ensure the float seat is present Figure 3 State, the conditions for the bottom lead pendant to fall smoothly:

[0014] G1×L1>G2×L2+G3×L3

[0015] Ensure that the bottom lead falls to the ground and presents Figure 4 State, the weight slide lead quickly slides close to the wire entry hole conditions:

[0016] G1×L1<G2×L2+G3×L3

[0017] Float selection conditions:

[0018] The float should preferably be a thick-tailed vertical float (the float tail must have a certain amount of buoyancy), which is more in line with the habits of most anglers. You can also use a surface float similar to a ball float, but it is not advisable to choose an ordinary thin-tailed vertical float.

[0019] Conditions to ensure that the tail of the float is above the water surface:

[0020] G1+G2+G3<F

[0021] Fishing line requirements:

[0022] The fishing line has a certain degree of softness, which can achieve Figure 4 state.

[0023] When the above conditions are met, the float seat enters the water because the torque on the outgoing line side is greater than the torque on the incoming line side. Figure 3 When the bottom lead falls to the bottom of the water, the torque on the outgoing line is smaller than the torque on the incoming line. Figure 4 The fishing line is locked and the whole process of fishing and finding the bottom is completed.

[0024] 2. Examples

[0025] In order to verify the effectiveness of the lever-type automatic bottom-finding float seat, it was actually made. The float seat is made of plastic and the values ​​are obtained through actual measurements.

[0026] Example 1: Main body tube: outer diameter 8mm, inner diameter 7mm, length 45mm; Piston type wire outlet tube: total length 30mm, outer diameter 5mm, inner diameter 3mm; Wire inlet hole: hole diameter 1.2mm; Counterweight lead slide: lead body diameter 6.5mm, hole inner diameter 1.2mm; L1=22mm, L2=12mm, L3=8mm, when the bottom lead sinker starts to fall, G1=3.0 grams, when the bottom lead sinker lands, G1=1.0 grams, G2=2.35 grams, G3=0.16 grams, F=4.62 grams (of which the float belly consumes 2.98 grams of lead, and the float tail consumes 1.64 grams of lead).

[0027] Ensure the float seat is present Figure 3 State, calculation of the conditions for the smooth falling of the bottom lead pendant:

[0028] G1×L1=3×10×0.022=0.66 mm

[0029] G2×L2+G3×L3=2.35×10×0.012+0.16×10×0.008=0.2948 mNm

[0030] 0.66 mm>0.2948 mm, meeting the requirements.

[0031] Ensure that the bottom lead falls to the ground and presents Figure 4 State, the weight slide lead quickly slides close to the wire entry hole condition calculation:

[0032] G1×L1=1.0×10×0.022=0.22 mm

[0033] G2×L2+G3×L3=2.35×10×0.012+0.16×10×0.008=0.2948 mNm

[0034] 0.22 mmNm<0.2948 mmNm, which meets the requirements.

[0035] Float selection:

[0036] The float uses a thick tail float, of which the float belly holds 2.98 grams of lead and the float tail holds 1.64 grams of lead.

[0037] Calculation of conditions to ensure that the tail of the float is above the water surface:

[0038] G1+G2+G3=1+2.35+0.16=3.51 grams

[0039] F=4.62 g

[0040] 3.51 grams < 4.62 grams, and 1.64-(4.62-3.51) = 0.53 grams, which meets the conditions.

[0041] Fishing line selection:

[0042] Nylon wire No. 1, 2, 3, and 4; PE wire No. 0.6, 0.8, 1.0, 2.0, 3.0, and 4.0.

[0043] Verification results:

[0044] Nylon lines 1 and 2 meet all the conditions, but Nylon line 3 does not. Figure 4 State conditions, but by pushing and pulling the outlet tube, fine-tuning the force arm L1, L2 values, barely reaching Figure 4 State conditions: PE lines 0.6, 0.8, 1.0, 2.0, 3.0, 4.0 all meet all the conditions. Nylon lines 3 and 4 do not meet Figure 4The main reason is that as the nylon line number increases, the hardness also increases, making it difficult to bend. For hard fishing lines, the weight of the weighted lead must be increased and the float seat must be recalculated.

[0045] Example 2: Main body tube: outer diameter 10mm, inner diameter 8mm, length 70mm; piston type wire outlet tube: total length 53mm, outer diameter 5mm, inner diameter 3mm; wire inlet hole: hole diameter 1.2mm; counterweight lead slide: lead body diameter 7.5mm, hole inner diameter 1.2mm; L1=40mm, L2=27mm, L3=12mm, when the bottom lead sinker starts to fall, G1=7.0 grams, when the bottom lead sinker lands, G1=2.6 grams, G2=7 grams, G3=2.3 grams, F=15.2 grams (of which the float belly consumes 10 grams of lead, and the float tail consumes 5.2 grams of lead).

[0046] Ensure the float seat is present Figure 3 State, calculation of the conditions for the smooth falling of the bottom lead pendant:

[0047] G1×L1=7×10×0.04=2.8 mm

[0048] G2×L2+G3×L3=7×10×0.027+2.3×10×0.012=2.166 mNm

[0049] 2.8 mmNm>2.166 mmNm, meets the conditions.

[0050] Ensure that the bottom lead falls to the ground and presents Figure 4 State, the weight slide lead quickly slides close to the wire entry hole condition calculation:

[0051] G1×L1=2.6×10×0.04=1.04 mm

[0052] G2×L2+G3×L3=7×10×0.027+2.3×10×0.012=2.166 mNm

[0053] 1.04 mm<2.166 mm, which meets the requirements.

[0054] Float selection:

[0055] The float uses a thick tail float, of which the float belly holds 10 grams of lead and the float tail holds 5.2 grams of lead.

[0056] Calculation of conditions to ensure that the tail of the float is above the water surface:

[0057] G1+G2+G3=2.6+7+2.3=11.9 grams

[0058] F=15.2g

[0059] 11.9 grams < 15.2 grams, and 5.2-(15.2-11.9) = 3.3 grams, which meets the conditions.

[0060] Fishing line selection:

[0061] Nylon wire No. 1, 2, 3, 4, 6, 8, and 10; PE wire No. 1.0, 2.0, 3.0, 4.0, 6, and 8.

[0062] Verification results:

[0063] Nylon threads No. 1, 2, 3, 4, 6, and 8 meet all the conditions, but No. 10 does not. Figure 4 The main reason is that as the line number increases, the hardness of the fishing line also becomes greater; PE lines 1.0, 2.0, 3.0, 4.0, 6, and 8 all meet all conditions.

[0064] The verification results show that:

[0065] The heavier the weight of the lead counterweight, the wider the range of applicable fishing lines, especially hard fishing lines like nylon lines, so corresponding float seats can be made according to different usage requirements and ranges.

[0066] It is best to use a thick tail vertical float (the tail must have a certain buoyancy), which greatly reduces the impact of wind and waves and has a wider range of applications. You can also use a surface float similar to a ball float, but its wind and wave resistance is relatively poor.

[0067] from Figure 3 Status changes to Figure 4 After the float is in this state, the counterweight slides downward under its own gravity, locking the fishing line in place. The bending angle of the fishing line at the outlet port becomes larger, and the friction here also becomes larger. Under the combined effect of the two, the fishing line is completely locked, preventing the locked fishing line from loosening and making the float state unstable. The effect is basically equivalent to a fixed float in table fishing.

[0068] The minimum weight of the bottom lead sinker of the float seat is relatively light. In the example, the smallest bottom lead sinker is only 3 grams, which can be easily pulled by small fish. In fact, the bottom lead sinker can be made lighter.

[0069] After the float is connected to the float seat, the whole is equivalent to a self-standing float, which is more stable and has a certain ability to resist water leakage.

[0070] The structural characteristics of the float seat are fully capable of sliding float. After lifting the rod, it slides down freely and automatically finds the bottom after entering the water. It fits closely with the entire fishing process and does not require human intervention.

[0071] The structure is simple and easy to install, disassemble and thread.
