Description

Technical Field

[0001] This utility model relates to a fishing reel, specifically a spindle-type fishing reel with an anti-collision transmission mechanism. Background Technology

[0002] A spinning reel is a type of fishing tackle that includes a main body, a main shaft, a gear rod, a gear disc, a line housing, and a reel. To facilitate line feeding on the spinning reel, a transmission mechanism is installed within the main body. This transmission mechanism typically consists of a gear disc, a gear rod, a main shaft, a pinion, a drive gear, and a slider. The gear disc and pinion are coaxially mounted and driven by a rocker arm. This driving force is divided into two outputs. One output is the meshing of the gear disc and the gear rod, which is mounted on the main body. The line housing is mounted on the gear rod, forming the first transmission mechanism, which allows the line housing to rotate. The second transmission mechanism converts the rotational motion of the main shaft into axial reciprocating motion through the meshing of a pinion and a transmission gear. An eccentric column is fixed to the transmission gear, with its other end located in a groove in a slider. The slider is fixed to the main shaft, and the reel is mounted at the front end of the main shaft. The rotational motion of the transmission gear is converted into axial reciprocating motion of the main shaft through the interaction of the eccentric column and the slider, which in turn drives the reel to reciprocate axially. In other words, the rotational motion of the line housing, combined with the axial reciprocating motion of the reel, achieves uniform line laying on the spinning reel. Such a transmission mechanism is disclosed in documents such as Chinese Patent Application Publication No. CN108990931A and Chinese Patent Grant Announcement No. CN210841243U.

[0003] However, during use, it was discovered that because the spinning reel's line housing and gear can only rotate in one direction (a one-way bearing is installed between the gear and the main body, rotating along with the rocker arm during line reeling), when the spinning reel is subjected to external impact, such as falling to the ground, the impact force is fed back to the space between the gear and the gear disc, and between the pinion and the drive gear, causing them to break, especially the pinion and drive gear. The existing transmission mechanism lacks anti-collision measures, directly rendering the spinning reel unusable. Therefore, further improvements are needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an anti-collision transmission mechanism for a spinning wheel-type fishing reel, which makes the spinning wheel-type fishing reel have a longer service life, in light of the current state of the technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an anti-collision transmission mechanism for a spinning reel, comprising a small gear, a transmission gear, a main shaft for mounting the reel, and a slider mounted on the main shaft, wherein the small gear can rotate together with the winding direction of the rocker arm of the spinning reel, the transmission gear has transmission teeth on its circumference that mesh with the small gear, and an eccentric column is fixed on the end face of the transmission gear facing the slider, one end of the eccentric column being inserted into the groove of the slider, so that the rotational motion of the transmission gear can be converted into the axial motion of the main shaft. The reciprocating motion is characterized in that: the transmission gear includes a first transmission wheel with the aforementioned transmission teeth and a second transmission wheel with the aforementioned eccentric column, which are coaxially mounted. The opposite end faces of the first and second transmission wheels are provided with mutually meshing one-way teeth, and an elastic element is configured to ensure that the one-way teeth on the first and second transmission wheels always have a tendency to mesh with each other. The one-way teeth allow the first and second transmission wheels to mesh and rotate together with the winding direction of the rocker arm, and when an external force forces the first transmission wheel to rotate in the opposite direction of winding, the one-way teeth allow the first transmission wheel to rotate relative to the second transmission wheel.

[0006] Preferably, the elastic element is a wave-shaped washer or a spring, arranged on the same side as the eccentric column and sleeved and confined on the shaft. The wave-shaped washer or spring can better meet the elasticity required for engagement or disengagement between the first and second transmission wheels, and is easy to install.

[0007] To facilitate the positioning of the aforementioned wave-shaped gasket or spring, one end of the shaft is fixed to the inner wall of the housing, and the other end is threaded with a fastener that abuts against the wave-shaped gasket or spring.

[0008] To facilitate coaxial installation, a bushing extends from the middle of the second drive wheel toward the first drive wheel for the shaft to pass through. This bushing can pass through the shaft hole of the first drive wheel.

[0009] In the above embodiments, it is further preferred that the meshing surface of each one-way tooth is composed of a radially distributed vertical surface, an inclined surface arranged circumferentially and gradually rising towards the vertical surface, and a plane connecting the top of the vertical surface and the top of the inclined surface, and adjacent one-way teeth have a connecting surface that meshes with the plane on the corresponding one-way tooth.

[0010] Compared with the prior art, this utility model makes the transmission gear into a split first transmission wheel and second transmission wheel. The transmission is achieved by the transmission teeth on the first transmission wheel meshing with the pinion, and the eccentric column on the second transmission wheel cooperating with the groove on the slider. At the same time, with the help of the one-way teeth between the first and second transmission wheels, they can rotate together with the rocker arm to achieve the line reeling function during normal reeling. However, once they are subjected to an external force that makes them rotate in the opposite direction of line reeling (such as during an impact), the first and second transmission wheels can rotate relative to each other. This allows the external force to be collapsed and absorbed by the relative rotation of the first and second transmission wheels, thereby effectively avoiding damage to the transmission gears, pinion, and other components, and thus extending the service life of the fishing reel.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

Since the embodiments disclosed in this invention can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0019] like Figure 1 The image shows a spinning reel, comprising a housing, a reel 10, a line housing 20, and an anti-collision transmission mechanism. The housing includes a main body (not shown) and a main cover 30 fixed to the side of the rear of the main body by screws. The anti-collision transmission mechanism is located at the rear of the spinning reel's housing, as shown... Figures 2 to 6 As shown, it includes a pinion 1, a transmission gear 2, a main shaft 3, a slider 4, and an eccentric column 5. The pinion 1, like in the prior art, is mounted on a spindle 7 along with a gear disc 6. The spindle 7 is supported by bearings on the main body and the main cover 30. A rocker arm 8 is mounted at one end of the spindle 7, and a protective cover 40 is provided at the other end of the spindle 7, which is fixed to the main body. That is, rotating the rocker arm 8 drives the spindle 7, gear disc 6, and pinion 1 to rotate together. The end of the eccentric column is inserted into the groove 41 of the slider 4, and the slider 4 is fixed to the main shaft 3. The gear disc 6 is located on one side of a rack 9 and meshes with the rack 9. The rack 9 is fitted onto the main shaft 3 and supported within the main body by bearings. A spool 10 is mounted on the main shaft 3, and a wire housing 20 is mounted on the rack 9. When the rocker arm 8 is rotated, the wire wheel 10 can be driven to reciprocate along the axis of the main shaft 3 via the pinion 1, transmission gear 2, eccentric column 5, slider 4, and main shaft 3. At the same time, the wire shell 20 is driven to rotate via the gear plate 6 and gear rod 9. This transmission path is the same as the existing technology and will not be explained in detail.

[0020] In this embodiment, the transmission gear 2 is designed as a split structure, that is, the transmission gear includes a first transmission wheel 21 and a second transmission wheel 22 mounted coaxially. The first transmission wheel 21 has transmission teeth on its periphery that mesh with the pinion 1. The eccentric column 5 is disposed on the end face of the second transmission wheel 22. That is, the first transmission wheel 21 is used to mesh with the pinion 1, and the eccentric column 5 on the second transmission wheel 22 is used to cooperate with the slide groove 41 on the slider 4. Meanwhile, on the opposite end faces of the first transmission wheel 21 and the second transmission wheel 22, there are also meshing one-way teeth 23, and an elastic element 02 is configured. Specifically, the elastic element can be a wave-shaped washer (or a spring), arranged on the same side as the eccentric column and sleeved and limited on the shaft 01. In the figure, one end of the shaft 01 is fixed to the inner wall of the main body, and the other end is threaded with a fastener 03 that abuts against the wave-shaped washer (or spring). The fastener 03 can be a bolt. At this time, the other end of the shaft 01 has a threaded hole. Of course, the fastener can also be a nut. At this time, the other end of the shaft is designed as a screw. The nut is threadedly connected to the screw to achieve the purpose of pressing the wave-shaped washer (or spring), thereby allowing the wave-shaped washer (or spring) to abut against the second transmission wheel 22, so that the one-way teeth on the first and second transmission wheels always have a tendency to mesh with each other.

[0021] Meanwhile, considering the convenience of assembly and the reliability of transmission, the middle part of the second transmission wheel 22 extends toward the first transmission wheel to form a bushing 221 through which the shaft 01 passes. The bushing 221 can pass through the shaft hole 211 of the first transmission wheel 21.

[0022] The aforementioned one-way tooth 23 needs to meet the following conditions: it should allow the first drive wheel 21 and the second drive wheel 22 to mesh and rotate together with the take-up direction of the rocker arm, thus achieving normal take-up function; when an external force forces the first drive wheel 21 to rotate against the take-up direction, the one-way tooth 23 should allow the first drive wheel 21 to rotate relative to the second drive wheel 22. During this process, the first drive wheel 21 needs to overcome the force of the elastic element 02. Preferably, the meshing surface of the one-way tooth 23 consists of radially distributed vertical surfaces 231, circumferentially arranged inclined surfaces 232 that gradually rise towards the vertical surfaces, and a plane 233 connecting the top of the vertical surfaces and the top of the inclined surfaces. Adjacent one-way teeth have a connecting surface 234 that meshes with the plane on the corresponding one-way tooth. Thus, during normal take-up, the first drive wheel will rotate according to the rocker arm's direction. Figure 5 , Figure 6When the arrow in the diagram indicates rotation, the vertical surfaces 231 on the corresponding one-way teeth 23 mesh with each other, allowing the first drive wheel 21 and the second drive wheel 22 to rotate together in only one direction. When subjected to a reverse force, due to the inclined contact, the first drive wheel 21 will overcome the force of the elastic element 02 and climb up the inclined plane, rotating relative to the second drive wheel 22. This means that slippage will occur between the two, thereby absorbing the impact force of external forces, achieving the purpose of collapsing and absorbing energy, avoiding damage to the components in the transmission mechanism due to large impact forces, and ensuring that the spinning reel can still work normally after an impact.
