Description

Technical Field

[0001] This utility model relates to the field of fishing reel technology, and in particular to a fishing reel unloading alarm mechanism. Background Technology

[0002] The fishing reel uses a brake mechanism installed on the reel to buffer the instantaneous tension on the fishing line when a fish bites and escapes. In addition, to improve the sense of playing the fish after it bites, a stress relief alarm mechanism is added to the brake mechanism of the reel. The ticking sound emitted by the stress relief alarm mechanism indicates the state of line release caused by the fish breaking free of the braking force.

[0003] The unloading alarm mechanism usually produces sound through the relative rotation between the sound-generating disc and the sound-generating gear ring. The sound-generating gear ring is fixed inside the main gear of the cable reel. The existing fixing methods usually use adhesive or snap rings, but this method results in low installation efficiency, poor braking effect, and the sound-generating gear ring is easy to fall off, affecting the overall sound generation and braking effect. Moreover, once the gear ring or the main gear is damaged, the whole thing needs to be replaced, which increases the replacement cost. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fishing reel unloading alarm mechanism that is easy to install, has a good braking effect, stable sound output, and is easy to maintain and replace.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fishing reel unloading alarm mechanism includes a main shaft, a main gear, a sound-generating disc, a sound-generating gear ring, and an intermediate pressure plate. The main gear is rotatably mounted on the main shaft, and a receiving cavity is formed on the surface of the main gear. The sound-generating gear ring and the intermediate pressure plate are sequentially sleeved on the main shaft along the axial direction and placed in the receiving cavity. The sound-generating disc is located inside the sound-generating gear ring and rotates with the main shaft to cooperate with the sound-generating gear ring to generate sound. A first braking element is provided between the sound-generating disc and the intermediate pressure plate, and a second braking element is provided between the intermediate pressure plate and the receiving cavity. A first lug is fixed on the outer side of the intermediate pressure plate, and a second lug is fixed on the outer side of the sound-generating gear ring. A first groove, a second groove, and a limiting groove connected to the second groove are formed on the inner wall of the receiving cavity. The first lug is fitted into the first groove, and the second lug passes through the second groove and then enters the limiting groove in the opposite direction to the rotation direction of the main gear when generating sound. The intermediate pressure plate, with the cooperation of the first lug and the first groove, is fixed circumferentially with the main gear, and under the action of the second brake, provides a braking force to restrict the relative rotation of the main gear and the main shaft. The second lug of the sound-emitting gear ring is aligned with the second groove of the main gear and inserted. Then, the sound-emitting gear ring is rotated so that the second lug enters the limiting groove, completing the fixation of the sound-emitting gear ring and the main gear, which is convenient for installation. When the main gear rotates relative to the sound-emitting disk, since the direction in which the second lug enters the limiting groove is opposite to the direction of rotation, the sound-emitting disk generates a tangential force on the sound-emitting gear ring when it cooperates with the sound-emitting gear ring to produce sound. The second lug uses this tangential force to always press against the inner wall of the limiting groove, so that the sound-emitting gear ring is firmly fixed in the main gear and does not come off, ensuring the sound-emitting performance of the entire unloading alarm mechanism. In addition, the first brake and the second brake work together to brake, ensuring a better braking effect.

[0006] There are at least two first lugs, which are arranged at intervals on the outside of the middle pressure plate. There are at least two second lugs, which are arranged at intervals on the outside of the sound-generating tooth ring. The first groove corresponds to the first lug, and the second groove corresponds to the second lug.

[0007] Two limiting grooves are connected to the second groove, symmetrically arranged on both sides of the center of the second groove. The presence of limiting grooves on both sides of the center of the second groove simultaneously accommodates the installation requirements of the main gear in both left-hand and right-hand fishing reels.

[0008] The depth of the limiting groove is gradually reduced in the direction away from the second groove.

[0009] The first brake component includes a first brake pad, which is movably fitted onto the main shaft through a circular hole.

[0010] The second brake component includes a second brake pad, an intermediate pad, and a third brake pad arranged sequentially below the intermediate pressure plate along the main shaft axis. The intermediate pressure plate rotates with the main shaft through a shaft hole, and the second brake pad and the third brake pad are movably sleeved on the main shaft through a round hole.

[0011] The bottom of the second groove is flush with the bottom of the limiting groove.

[0012] The sum of the distance between the bottom of the second lug and the bottom of the sound-generating toothed ring and the thickness of the first lug is not greater than the vertical height between the bottom of the limiting groove and the bottom of the first groove.

[0013] The bottom of the sound-generating toothed ring extends into a toothless ring portion, and the second lug is formed on the outside of the toothless ring portion. The toothless ring portion is provided with an avoidance notch, which is configured to provide the displacement space required for the first lug when the sound-generating toothed ring rotates relative to the intermediate pressure plate.

[0014] The surface of the sound-generating disc is provided with a mounting groove, and the wall of the mounting groove is provided with a side hole communicating with the outside. A bent spring is provided in the mounting groove. One end of the bent spring is open and forms a snap-fit ​​part that is elastically pressed against the wall of the mounting groove. The other end of the bent spring is closed and extends out of the side hole to form a toothed part. The toothed part cooperates with the inner tooth surface of the sound-generating tooth ring to generate sound.

[0015] This utility model has the following beneficial effects: This invention provides a better braking effect for the fishing reel's reel by setting a first brake and a second brake between the intermediate pressure plate and the main gear, and between the sound-generating disc and the intermediate pressure plate, respectively. The intermediate pressure plate, with the cooperation of the first lug and the first groove, is circumferentially fixed to the main gear. The second lug of the sound-generating gear ring is inserted into the second groove of the main gear and then rotated into the limiting groove to complete the fixation of the sound-generating gear ring and the main gear. The installation is convenient and the sound-generating gear ring or the main gear is easy to replace. When the main gear rotates relative to the sound-generating disc, since the direction in which the second lug enters the limiting groove is opposite to the direction of rotation, the actuating teeth of the sound-generating disc generate a tangential force on the sound-generating gear ring. The second lug is always pressed against the inner wall of the limiting groove by this tangential force. Throughout the sound-generating process, the sound-generating gear ring is firmly fixed in the main gear and does not detach, ensuring good sound performance. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] like Figure 1 and Figure 2As shown, a fishing reel unloading alarm mechanism includes a main shaft 1, a main gear 2, a sound-emitting disc 4, a sound-emitting gear ring 3, and an intermediate pressure plate 5. The rotating shaft of the main shaft 1 is non-cylindrical, and the main gear 2 has a circumferential hole in its middle. The main gear 2 is rotatably mounted on the main shaft 1 through the circumferential hole. Figure 4 As shown, the surface of the main gear 2 has a receiving cavity 201. The sound-generating gear ring 3 and the intermediate pressure plate 5 are sequentially fitted onto the main shaft 1 through the circumferential hole and placed in the receiving cavity 201. The sound-generating disk 4 is located inside the sound-generating gear ring 3. The center of the sound-generating disk 4 has a non-cylindrical shaft hole that mates with a non-cylindrical body. It rotates with the main shaft 1 and mates with the sound-generating gear ring 3 to generate sound. Specifically, in this scheme, as shown... Figure 9 As shown, the inner side of the sound-generating gear ring 3 is formed with an internal tooth surface, and the surface of the sound-generating disc 4 is provided with a mounting groove 401. A side hole 402 communicating with the outside is provided on the groove wall of the mounting groove 401. A bent spring 10 is provided inside the mounting groove 401. One end of the bent spring 10 is open and forms a snap-fit ​​portion that elastically presses against the groove wall of the mounting groove 401. The other end of the bent spring 10 is closed and extends out of the side hole 402 to form a prying tooth portion 1001. This prying tooth portion 1001 cooperates with the internal tooth surface of the sound-generating gear ring 3 to produce sound; a further preferred embodiment; such as... Figure 2 and Figure 6 As shown, a first braking component is provided between the sound-generating disc 4 and the intermediate pressure plate 5, and a second braking component is provided between the intermediate pressure plate and the receiving cavity 201, as shown. Figure 3 As shown, a first lug 501 is fixed to the outer side of the intermediate pressure plate 5, and a first groove 202 is provided on the inner wall of the receiving cavity 201. The first lug 501 is fitted into the first groove 202 so that the intermediate pressure plate 5 rotates together with the main gear 2. The second brake provides braking force between the two when they rotate relative to the main shaft 1. A second lug 301 is fixed to the outer side of the sound-generating gear ring 3, and a second groove 203 and a limiting groove 204 connected to the second groove 203 are provided on the inner wall of the receiving cavity 201. After the second lug 301 passes through the second groove 203, it fits into the limiting groove 204 in the opposite direction to the rotation direction of the main gear 2 when producing sound, thus completing the axial and circumferential fixation of the sound-generating gear ring 3 on the main gear 2. The process is convenient and quick. When the sound-generating gear ring 3 needs to be replaced, it is only necessary to rotate the sound-generating gear ring 3 in the reverse direction to disengage the second lug 301 from the second groove 203. Maintenance is convenient. The first brake provides braking force to the sound-generating disk 4 that rotates with the main shaft 1 and the intermediate pressure plate 5 that rotates with the main gear 2. It works in conjunction with the second brake to provide a better braking effect. When the main gear 2 rotates relative to the sound-generating disk 4, since the direction in which the second lug 301 enters the limiting groove 204 is opposite to the direction of rotation, the actuating teeth of the sound-generating disk 4 generate a tangential force on the sound-generating gear ring 3. The second lug 301 is always pressed against the inner wall of the limiting groove 204 by this tangential force, so that the sound-generating gear ring 3 is firmly fixed in the main gear 2 throughout the sound generation process and does not disengage, thus ensuring its good sound generation performance.

[0022] More preferably, there are at least two first lugs 501, spaced apart on the outer side of the intermediate pressure plate 5, and at least two second lugs 301, spaced apart on the outer side of the sound-generating gear ring 3. The first groove 202 corresponds one-to-one with the first lug 501, and the second groove 203 corresponds one-to-one with the second lug 301. Specifically, in this scheme, there are two first lugs 501 and two second lugs 301. The center line connecting the two first grooves 202 and the center line connecting the two second grooves 203 pass through the center of the main gear 2 and are perpendicular to each other to ensure the stability of their cooperation.

[0023] Since fishing reels exist in both left-hand and right-hand versions, to ensure proper installation and fit between the main gear 2 and the sound-generating gear ring 3 in both types of reels, such as... Figure 3 As shown, there are two limiting grooves 204 that communicate with each of the second grooves 203. They are symmetrically arranged on both sides of the center of each second groove 203. According to the rotation direction of the main gear 2 in the fishing reel to be produced, the corresponding sound-generating gear ring 3 is rotated in the opposite direction to assemble.

[0024] Further preferred, such as Figure 3 As shown, the depth of the limiting groove 204 is gradually reduced in the direction away from the second groove 203. The distance between the bottom of the groove where the limiting groove 204 connects with the second groove 203 and the center of the main gear 2 is greater than the distance between the far end of the second lug 301 and the center of the sound-emitting gear ring 3. After the alarm mechanism is assembled, as the actuating teeth of the sound-emitting disc 4 apply force to the sound-emitting gear ring 3 more times, the second lug 301 will fit more and more tightly with the groove wall of the limiting groove 204 in the gradually reducing depth under the action of tangential force, thereby making the stability of the sound-emitting gear ring 3 better.

[0025] To facilitate the rapid assembly of the sound-generating gear ring 3 onto the main gear 2, such as Figure 4 As shown, the bottom of the second groove 203 is flush with the bottom of the limiting groove 204.

[0026] Further preferred, in Example 1, such as Figure 5 As shown, the bottom of the sound-generating toothed ring 3 extends into a toothless ring portion 302, and the second lug 301 is formed on the outer side of the toothless ring portion 302. With this arrangement, the limiting groove 204 that mates with the second lug 301 is located in the lower middle part of the inner wall of the receiving cavity 201, thereby ensuring the machining strength of the limiting groove 204. Figure 6 As shown, the assembled intermediate pressure plate 5 is located within the toothless ring portion 302 of the sound-generating gear ring 3. To avoid interference from the first lug 501 of the intermediate pressure plate 5 during the rotational installation of the sound-generating gear ring 3, as shown... Figure 5As shown, the toothless ring portion 302 is provided with a clearance notch 303, which provides the displacement space required for the first lug 501 when the sound-generating toothed ring 3 and the intermediate pressure plate 5 rotate relative to each other.

[0027] In Example 2, as Figure 7 As shown, the sound-generating gear ring 3 adopts a fully internal gear structure, and the second lug 301 is formed on the outer side of the sound-generating gear ring 3. In this case, compared to embodiment 1, the thickness of the main gear 2 is increased, and the depth of the mounting cavity 201 is increased, as shown... Figure 8 As shown, the sum of the distance d1 between the bottom of the second lug 301 and the bottom of the sound-generating tooth ring 3 and the thickness d2 of the first lug 501 is not greater than the vertical height d3 between the bottom of the limiting groove 204 and the bottom of the first groove 202, so that the intermediate pressing plate 5 after conversion is located below the sound-generating tooth ring 3, and the limiting of the intermediate pressing plate 5 and the limiting of the sound-generating tooth ring 3 do not interfere with each other.

[0028] like Figure 2 As shown, the first brake component includes a first brake pad 6, which is movably sleeved on the main shaft 1 through a circular hole; the second brake component includes a second brake pad 7, an intermediate pad 8, and a third brake pad 9 arranged sequentially below the intermediate pressure plate 5 along the axial direction of the main shaft 1. The intermediate pressure plate 5 rotates with the main shaft 1 through a shaft hole. The second brake pad 7 and the third brake pad 9 are movably sleeved on the main shaft 1 through circular holes. Specifically, the first brake pad 6, the second brake pad 7, and the third brake pad 9 are carbon fiber pads. During braking, the sound-generating disc 4, the intermediate pressure plate 5, the intermediate pad 8, and the main gear 2 are braked through the three brake pads. The braking force is large, which can effectively shorten the line distance when the fish escapes; at the same time, during the braking process, the sound-emitting disc 4 and the main gear 2 rotate relative to each other, and the prying part 1001 of the sound-emitting disc 4 pries the inner tooth surface of the sound-emitting gear ring 3 to produce a sound. Through this sound, the angler can clearly know that the line has been released and adjust the braking force in time (that is, apply pressure to the braking components through the adjustment mechanism to reduce the distance between each shim), thereby increasing the chance of catching fish; of course, in order to ensure the adjustability of the above shims, the distance between the bottom of the first groove 202 and the bottom of the receiving cavity 201 is not greater than the sum of the minimum thickness of the second brake shim 7, the third brake shim 9 and the middle shim 8 after compression.

[0029] When implementing this technical solution, the third brake pad 9, the intermediate pad 8, and the second brake pad 7 are sequentially passed through the main shaft 1 and placed in the receiving cavity 201 of the main gear 2. The intermediate pressure plate 5 is aligned with the first groove 202 of the main gear 2 through the first lug 501. The sound-emitting gear ring 3 is aligned with the second groove 203 of the main gear 2 through the second lug 301 and then rotated until it reaches the limit. Then, the first brake pad 6 and the sound-emitting disc 4 are sequentially passed through the main shaft 1 and placed inside the sound-emitting gear ring 3. The toothed part 1001 of the sound-emitting disc 4 cooperates with the toothed part of the sound-emitting gear ring 3 to complete the assembly of this force-relieving alarm mechanism. The entire installation process is convenient to operate, the alarm mechanism has a good braking effect, and the sound effect is stable.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
