A device for preventing fishing line from winding around the center spindle of a eight-gossip wheel disc car and enhancing the thrust of brake pads

Abstract

The utility model relates to a device for preventing fish line from winding around the center spindle of a eight-gu wheel disc cycle and enhancing the pushing force of brake pads, belonging to the technical field of fishing gear. The device is aimed at the problem that the eight-gu wheel disc cycle with a brake knob is prone to have fish line fall into the gap between the hand shaft and the brake knob and wind around the center spindle, and solves the problem through structure optimization. Its main features are: the brake knob is provided with an annular surrounding ring at one end facing the hand shaft to form a peripheral wall, and the inner side of the peripheral wall is provided with an annular step and surrounds a brake pad supporting platform; the end of the hand shaft is inserted into the inside of the peripheral wall, and a very small radial gap is reserved between the two to avoid friction; when the brake knob is rotated, the supporting platform pushes the brake pad to press against the hand shaft to generate braking force. This structure can effectively prevent fish line from falling into the gap and enhance the pushing force of the brake pad, avoid the winding of fish line around the center spindle, and make the line releasing operation simple and fast.

Description

Technical Field

[0001] This utility model relates to the field of fishing gear, specifically to the Bagua wheel reel (also called a wheel reel, hand-operated wheel, grain wheel, raft wheel, rushing reel, etc.), providing a device to prevent fishing line from getting tangled in the central main shaft of the Bagua wheel reel and to enhance the thrust of the brake pads. Background Technology

[0002] Currently, octagonal reel fishing is widely used, commonly in stream fishing, lake and reservoir fishing, and raft fishing. Octagonal reel reels with brake knobs are more convenient, but a common problem is that fishing line often gets caught in the gap between the hand lever shaft and the brake knob, usually wrapping directly around the central spindle. This makes it difficult to untangle the line, typically requiring cutting the line or removing the reel. This invention aims to improve the structure and fit of the components to prevent fishing line from getting caught in the gap between the hand lever shaft and the brake knob, thus preventing the line from wrapping around the central spindle. Summary of the Invention

[0003] This utility model is designed for a Bagua wheel trolley with a brake knob or similar intermediate body. Its main purpose is to prevent fishing line from getting tangled in the central spindle of the trolley, so as to facilitate untangling the line.

[0004] The technical solution adopted in this utility model is: a device for preventing fishing line from getting tangled in the central spindle of a roulette wheel and enhancing the thrust of the brake pads, comprising a central spindle, a brake knob, brake pads, and a hand lever shaft. The brake knob has an annular surrounding ring at one end facing the hand lever shaft, forming an outer wall of the brake knob. An annular step is provided at the inner root of the outer wall of the brake knob, surrounding a brake pad support platform. The end of the hand lever shaft is inserted into the outer wall of the brake knob, with a very small radial gap between them, solely for preventing contact friction. When the brake knob is rotated, the brake pad support platform pushes the brake pads against the hand lever shaft to generate braking force.

[0005] Preferably, the end of the hand crank shaft is an integral structure that has not been thinned.

[0006] Preferably, the hand lever shaft has a thinned, two-layer annular end face structure with a lower inner surface and a higher outer surface. The end face has two different surfaces, with the thinned portion forming a lower end face, which becomes the inner ring of the hand lever shaft end. The original end face that is not thinned is higher and becomes the outer ring of the hand lever shaft end. The outer ring corresponds to the annular step, and the inner ring corresponds to the brake pad and the brake pad support platform. The brake pad presses against the inner ring of the hand lever shaft end to generate braking force.

[0007] Preferably, the outer ring at the end of the hand crank shaft is made of a high-strength metal tube sleeved around the hand crank shaft. In this case, the outline of the hand crank shaft remains unchanged, but the strength and deformation resistance of the outer ring can be greatly improved.

[0008] Preferably, the central spindle is fixed on the base, which includes any one of a plate base, a trapezoidal base, and a tubular base, or the spindle passes through the rod body so that the rod body also serves as the base.

[0009] Beneficial effects: This device optimizes the contact area between the brake knob and brake pads on the Bagua wheel car, and also optimizes its cooperation with the hand lever shaft. The brake pads are almost entirely supported by the brake pad support platform, which not only enhances the stability and thrust of the brake pads, but also prevents the fishing line from falling into the gap between the hand lever shaft and the brake knob, thereby preventing the fishing line from getting tangled in the central shaft. This makes it easy to quickly untangle the tangled fishing line, which can enhance the enjoyment of fishing and is beneficial to physical and mental health.

[0010] The inventor of this utility model, Chen Jiaguo, applied for and was granted a utility model patent in 2023, entitled "A Braking Device for Rotary Wheels" (application number 202321882123.3), which can achieve high force relief, anti-lock braking, and anti-fall-off. That device solved an important problem of braking rotary wheels, but neglected the structural optimization of the brake knob, resulting in the problem that the main line might fall into the gap between the hand lever shaft and the brake knob, and then become entangled in the central main shaft. This utility model addresses its shortcomings by improving the structural form and engagement method of the existing brake knob, concealing the gap, while still ensuring a nearly complete support platform for the brake pads, allowing the brake pads to be firmly pressed against the brake pad support platform by the spring. The combination of the previous technology and this utility model can complement each other to achieve better performance and user experience. Attached Figure Description

[0013] like Figure 1 As shown, the end of the hand lever shaft 5 does not need to be thinned. The annular step 25 is located at the root of the inner side of the outer wall 6 of the brake knob, i.e., at the waist of the brake knob 7. This shows the state where the turntable can rotate freely. The center of the brake knob 7 has an embedded nut 23 to obtain a high-strength brake knob internal thread 8. Except for the anti-rotation teeth in the inner hole and the axial projection area of ​​the embedded nut 23, the brake pad 10 is almost entirely supported by the brake pad support platform 21 of the brake knob 7. Due to its different material, the embedded nut 23 is designed to be slightly shorter and lower than the support platform, and does not constitute part of the brake pad support platform 21. The brake pad support platform 21 not only enhances the posture stability of the brake pad 10, but also enables it to withstand greater thrust. To brake, rotate the brake knob 7. Under the action of the internal thread 8 of the brake knob and the external thread 22 of the main shaft, the brake pad support platform pushes against the back of the brake pad 10, pressing against the end face 11 of the hand lever shaft. The greater the pressure, the greater the braking force. The brake pad 10 has an anti-rotation function, so it will not lock the turntable. After rotating the brake knob 7 in the opposite direction to release the pressure, the hand lever shaft 5 and the turntable 20 can return to a free-rotating state. Here, the end 17 of the hand lever shaft is fully inserted into the outer wall 6 of the brake knob. If the fishing line falls out of the line groove 2 and into the gap between the turntable 20 and the base 12, the outer wall 6 of the brake knob will act as a shield, preventing the fishing line from falling into the gap between the hand lever shaft 5 and the brake pad 10, thus preventing the fishing line from tangling around the central main shaft 9. The friction ring 13 of the hand lever shaft is a flexible silicone ring, which helps with anti-slip and can also help guide the direction of the fishing line tangling. After the fishing line falls into the gap, it can only tangle on the visible outer surface of the components in the gap. Because the end 17 of the hand lever shaft is surrounded by the outer wall 6 of the brake knob, the radial gap between the two is extremely small, ensuring only that they do not come into contact or rub against each other, which further prevents the fishing line from getting tangled on the central main shaft 9. This makes it much easier to untangle the fishing line. If the applicant's utility model patent "A device for quickly untangling the main line of a disc wheel" (application number: 2025216362580) is used simultaneously, rapid untangling can be achieved.

[0014] The inventor of this utility model, Chen Jiaguo, applied for and was granted a utility model patent in 2023, entitled "A Braking Device for Rotary Wheels," application number 202321882123.3, which can achieve high force relief, anti-lock braking, and anti-fall-off. That device solved an important problem of braking rotary wheels, but neglected the structural optimization of the brake knob, resulting in the problem that the main line might fall into the gap between the hand lever shaft and the brake knob, and then become entangled in the central main shaft. This utility model addresses its shortcomings by improving the structural form and engagement method of the brake knob, concealing the gap, while still ensuring the near-complete support platform 21 required for the brake pads, and also ensuring that the brake pads 10 are firmly pressed against the brake pad support platform 21 by the spring. The brake pads 10 can always maintain an impartial posture, moving forward and backward together with the brake knob 7, and are always concealed by the outer wall 6 of the brake knob, making the whole system both stable and reliable. The combined use of the two technologies can complement each other, achieving better performance and user experience. Example

[0015] like Figure 2 As shown, the end of the hand crank shaft 5 has been thinned to resemble... Figure 5The two-layered annular end, with a higher outer ring and a lower inner ring, are shown: the outer ring 26 and the inner ring 27 of the hand lever shaft end. An annular step 25 is located at the root of the inner side of the outer wall 6 of the brake knob, i.e., the waist of the brake knob 7. The center of the brake knob 7 has an embedded nut 23 to obtain a higher-strength internal thread 8. The inner side of the outer wall 6 of the brake knob has an annular step 25. Here, it is shown that the brake pad 10, except for the anti-rotation teeth in the inner hole and the axial projection area of ​​the embedded nut 23, is almost entirely supported by the brake pad support platform 21 of the brake knob 7. Due to its different material, the embedded nut 23 is designed to be slightly shorter and lower than the platform, and does not constitute part of the brake pad support platform. The brake pad support platform 21 enhances the posture stability of the brake pad 10 and allows it to withstand greater thrust, pushing the brake pad 10 to compress the inner ring 27 of the hand lever shaft end to achieve braking. The outer ring 26 of the hand lever shaft end is inserted into the annular step 25 on the brake knob 7. The two interlock, and the outer wall 6 of the brake knob becomes a shield. When the fishing line falls into the gap between the turntable 20 and the base 12, this shield prevents the fishing line from falling into the gap between the brake pad 10 and the end face 11 of the hand lever shaft. The fishing line can only wrap around the outer surface of the parts in the gap and will not wrap around the central spindle 9, making it much easier to untangle the fishing line. In actual implementation, if the hand lever shaft 5 is made of plastic, in order to enhance the strength and deformation resistance of the thinner outer ring 26 of the hand lever shaft end, a structure in which a stainless steel tube with an inner and outer diameter adapted to the annular step is fitted around the hand lever shaft 5 can be used. While maintaining the outline of the hand lever shaft 5, this relatively thin part can be replaced. At this time, the end of the stainless steel tube naturally becomes the outer ring 26 of the hand lever shaft end. Compared with the first specific implementation method, this method increases the bending of the interlocking part, which can more thoroughly prevent the fishing line from wrapping around the central spindle. If the utility model patent "A device for quickly untangling the main line of a disc wheel" invented by one of the inventors, Chen Jiaguo, is used at the same time, rapid untangling can be achieved.
