Technical Field

[0001] The utility model relates to the technical field of fishing reel accessories, in particular to a gear ring which is easy to install and has adaptive elasticity and does not damage gears. Background Art

[0002] In fishing, among the fishing equipment used to reel in and out the fishing line, the two-axis or two-axis reel is called a water drop reel, a drum reel or a lure reel. The fishing reel has a braking force, which is used to drive the gear and apply it to the reel by rotating the main shaft through the handle to reel in. At present, a sounding device is provided in the reel to make a regular sound when the fishing line is pulled into the water, thereby increasing the fun of fishing and stimulating the desire of the angler to win.

[0003] The Chinese utility model patent with announcement number CN220734097U provides a fishing reel sound-making device, which provides a sound-making device, including a gear ring fixedly mounted inside the inner ring of the gear and a pressure plate mounted on the main shaft, wherein the pressure plate is provided with a torsion spring, and the inner ring of the gear ring is provided with a wave tooth, when the gear ring and the pressure plate rotate relative to each other, the wave tooth and the torsion spring move relative to each other, thereby making a sound.

[0004] During the installation of the ring gear, the usual practice is to use an interference fit method to embed the ring gear into the inner ring of the gear. During assembly, a jig is usually used to press the ring gear into the inner ring of the gear. However, since the ring gear and the gear are interference fit, there is a large pressure between them, which may damage the inner ring of the gear and affect the gear's service strength, or damage the structure of the ring gear and affect the performance of the ring gear.

[0005] Therefore, a new type of gear ring is urgently needed to avoid the above situation. Utility Model Content

[0006] The utility model aims to provide a gear ring which is easy to install and has adaptive elasticity without damaging the gear, so as to solve the above technical problems.

[0007] A gear ring which is easy to install and has adaptive elasticity without damaging the gear, is used to be assembled inside the gear of a winding wheel sound-generating device and is used to produce a sound in conjunction with a toggle component. The invention comprises a main body, wherein a wave tooth is arranged inside the main body, and an elastic structure which abuts against the inner wall of the gear is formed on the circumferential surface of the main body. The elastic structure comprises an abutting portion formed on the circumferential surface of the main body, and the abutting portions are provided with a plurality of abutting portions spaced apart from each other, and an elastic space is defined between two connected abutting portions.

[0008] Furthermore, a pressing piece is formed on the outer surface of the abutting portion, and the pressing piece protrudes from the outer surface of the abutting portion.

[0009] Furthermore, the pressing member has a pressing end extending outward, and a width dimension of the pressing end is smaller than a width dimension of a root portion of the pressing member.

[0010] Furthermore, the cross section of the elastic space is triangular or trapezoidal.

[0011] Furthermore, the cross section of the elastic space is an arc-shaped structure.

[0012] Furthermore, the cross section of the elastic space is rectangular.

[0013] Furthermore, a chamfer is provided at an outer edge of one end of the main body.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] In order to facilitate the installation of the gear ring, a chamfer is provided at the outer edge of one end of the main body, so that in the process of pressing the gear ring into the inner ring of the gear, it can enter in advance through the chamfer on the gear ring, and elastically deform along the circumferential direction through the abutment portion, so that the elastic space is compressed, and an elastic force is formed, so that the outer surface of the abutment portion and the inner wall of the gear abut each other. Furthermore, the clamping piece on the abutment portion can abut each other with the inner wall of the gear, which can further improve the stability of the abutment between the gear ring and the inside of the gear. In this embodiment, a pressing end is formed on the clamping piece, which can be pressed more firmly on the inner wall of the gear ring to ensure a stable installation of the gear ring. It is worth mentioning that although the ring gear is embedded in the inner wall of the gear by interference fit, by providing an elastic space between the abutting parts, the ring gear can have a certain elastic buffering capacity, which can absorb the pressure of the ring gear on the gear, prevent excessive pressure on the inner wall of the gear, avoid damage to the inner wall of the gear, ensure the performance of the gear, and at the same time ensure that there is enough low pressure between the ring gear and the gear, so that the ring gear can be firmly assembled on the gear.

[0026] The utility model provides a novel gear ring which can reduce the resistance force on the inner ring of the gear 20 through elastic buffering after being assembled on the gear 20, thereby avoiding damage to the gear 20. At the same time, the installation stability requirement of the gear ring can be guaranteed under the action of the elastic force.

[0027] Embodiment 1

[0028] like Figure 1-2As shown, this embodiment provides a gear ring that is easy to install and has adaptive elasticity without damaging the gear, which is used to be assembled in the gear 20 of the winding wheel sound-generating device and is used to make a sound in conjunction with the toggle component, including a main body 10, a wave tooth 11 is arranged inside the main body 10, and an elastic structure that abuts against the inner wall of the gear 20 is formed on the circumferential surface of the main body 10. The elastic structure includes an abutment portion 12 formed on the circumferential surface of the main body 10, and the abutment portion 12 is provided with a plurality of mutually spaced abutments, and an elastic space 13 is defined between two connected abutment portions 12. In this embodiment, the cross-section of the elastic space 13 is triangular or trapezoidal, and at the same time, a pressing member 14 is formed on the outer surface of the abutment portion 12, and the pressing member 14 protrudes from the outer surface of the abutment portion 12. The pressing member 14 has a pressing end extending toward the outer direction, and the width dimension of the pressing end is smaller than the width dimension of the root of the pressing member 14.

[0029] During the installation process, the gear 20 is fixedly mounted on the main shaft 30, and an inner ring is provided on the gear 20. The gear ring is pressed into the inner ring and is fixed by the mutual pressure between the gear ring and the inner wall of the inner ring.

[0030] To facilitate the installation of the ring gear, a chamfer 15 is provided at the outer edge of one end of the main body 10, so that in the process of pressing the ring gear into the inner ring of the gear 20, it can enter in advance through the chamfer 15 on the ring gear, and elastically deform along the circumferential direction through the abutment portion 12, so that the elastic space 13 is compressed, and an elastic force is formed, so that the outer surface of the abutment portion 12 and the inner wall of the gear 20 abut each other, and further, the clamping piece 14 on the abutment portion 12 can abut against each other. The stability of the abutment between the ring gear and the inside of the gear 20 can be further improved. In this embodiment, a pressing end is formed on the clamping piece 14, which can be pressed more firmly on the inner wall of the ring gear to ensure a stable installation of the ring gear. It is worth mentioning that although the ring gear is embedded in the inner wall of the gear 20 by means of interference fit, by providing an elastic space 13 between the abutting parts 12, the ring gear can have a certain elastic buffering capacity, which can absorb the pressure of the ring gear on the gear 20, prevent excessive pressure on the inner wall of the gear 20, avoid damage to the inner wall of the gear 20, ensure the performance of the gear 20, and ensure that there is a sufficiently low pressure between the ring gear and the gear 20, so that the ring gear can be firmly assembled on the gear 20.

[0031] Embodiment 2

[0032] In this embodiment, the main structure of the gear ring is substantially the same as that in the first embodiment. Figure 2-3As shown, in the present embodiment, the shape of the elastic space 13 is mainly changed. In the present embodiment, the cross-section of the elastic space 13 is arc-shaped, so that the interior of the elastic space 13 has an arc-shaped surface. By setting it as an arc-shaped structure, the gap between the abutting parts 12 can be gradually increased from the root toward the top, which can improve the ability of the abutting parts 12 to get close to each other, and can quickly and conveniently compress the elastic space 13, so that elastic deformation occurs more easily, ensuring that the compressive force on the gear 20 can be absorbed promptly and quickly, thereby preventing damage to the gear 20 caused by the compression.

[0033] Embodiment 3

[0034] In this embodiment, the structure of the gear ring is substantially the same as that of the embodiment, and in this embodiment, the structure and shape of the elastic space 13 are changed, such as Figure 5-6 As shown, in the present embodiment, the cross section of the elastic space 13 is rectangular. Through the above-mentioned setting, the cross section of the abutting portion 12 can also be roughly rectangular, and the span size of the elastic space 13 can be set, and the number of elastic spaces 13 can be adjusted. Through the above-mentioned structure, firstly, a larger contact area between the ring gear and the gear 20 can be ensured. At the same time, a certain number of elastic spaces 13 can be used to ensure that the ring gear has sufficient elastic deformation after being pressed into the gear 20, thereby ensuring that the ring gear will not generate a large abutting pressure on the gear 20, thereby avoiding damage to the gear 20.

[0035] For those skilled in the art, various other corresponding changes and deformations can be obtained according to the structure and principle disclosed by the utility model, and all of these changes and deformations belong to the protection scope of the utility model.
