Anti-collision transmission mechanism of spinning wheel type fishing reel

Abstract

An anti-collision transmission mechanism of a spinning wheel type fishing reel comprises a small gear, a transmission gear meshed with the small gear, a main shaft and a sliding block arranged on the main shaft, an eccentric column is fixed to the end face, facing the sliding block, of the transmission gear, and one end of the eccentric column is inserted into a sliding groove of the sliding block. The sliding block can be restrained on the main shaft in an axial sliding mode relative to the main shaft, meanwhile, a first elastic piece acting on the sliding block is arranged so that the sliding block can have the trend of moving towards the tail end of the main shaft all the time, and when the rocker arm rotates in the normal take-up direction, the first elastic piece can enable the sliding block to be fixed relative to the main shaft. During normal transmission take-up, the sliding block can still drive the main shaft to do axial reciprocating motion through the first elastic part, and once the sliding block is subjected to external force (such as generated during collision) which enables the sliding block and the main shaft to rotate in the direction opposite to the take-up direction, the sliding block and the main shaft slide relatively, so that the first elastic part crumples to absorb energy, and therefore damage to parts such as a transmission gear and a pinion is avoided, and the service life of the transmission gear is prolonged. Therefore, the purpose of prolonging the service life of the fishing reel is achieved.

Description

Technical Field

[0001] The invention relates to a fishing reel, in particular to an anti-collision transmission mechanism of a spinning-wheel type fishing reel. Background Art

[0002] The spinning reel is a type of fishing tackle among fishing reels, which includes a main body, a main shaft, a gear rod, a sprocket, a line housing and a reel. In order to smoothly arrange the line of the spinning reel, a transmission mechanism is installed in the main body. The transmission mechanism is usually composed of a gear disc, a gear rod, a main shaft, a pinion, a transmission gear and a slider. The gear disc and the pinion are coaxially installed and driven by a rocker arm. The driving force is divided into two outputs. One is the mutual engagement of the gear disc and the gear rod. The gear rod is installed on the main body, and the line housing is installed on the gear rod to form the first transmission mechanism, so that the line housing can obtain rotational power accordingly. The second transmission mechanism is to convert the axial reciprocating motion of the main shaft into the axial reciprocating motion of the main shaft through the meshing of the pinion and the transmission gear, wherein an eccentric column is fixed on the transmission gear, and the other end of the eccentric column is located in the slide slot of the slider, the slider is fixed to the main shaft as a whole, and the reel is installed at the front end of the main shaft. The rotational motion of the transmission gear is converted into the axial reciprocating motion of the main shaft through the cooperation of the eccentric column and the slider, and then the axial reciprocating motion of the reel can be driven, that is, the rotational motion of the line housing cooperates with the axial reciprocating motion of the reel to achieve uniform line arrangement of the spinning reel. For example, the documents of China Patent Application Publication No. CN108990931A and China Patent Authorization Announcement No. CN210841243U both disclose such a transmission mechanism.

[0003] However, it was found during use that since the line housing and gear rod of the spinning reel can only rotate in one direction (a one-way bearing is installed between the gear rod and the main body, and can rotate together with the rotation of the rocker arm when the line is reeled), when the spinning reel is hit by an external force, such as falling to the ground, the impact force will be fed back to the gear rod and the toothed disc, and between the pinion and the transmission gear, causing them to break, especially the pinion and the transmission gear. The above-mentioned breakage phenomenon is more likely to occur. However, there is no anti-collision measure on the existing transmission mechanism, which will directly lead to the spinning reel being unable to be used normally. Therefore, further improvement is needed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an anti-collision transmission mechanism for a spinning fish reel in view of the current status of the prior art, so that the service life of the spinning fish reel is extended.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: an anti-collision transmission mechanism of a spinning fish reel, comprising a pinion installed in the shell of the spinning fish reel, a transmission gear, a main shaft for installing the reel, and a slider arranged on the main shaft, wherein the pinion can rotate together with the winding direction of the rocker arm of the spinning fish reel, and the circumferential surface of the transmission gear is provided with transmission teeth meshing with the pinion, and an eccentric column is fixed on the end face of the transmission gear facing the slider, and one end of the eccentric column is inserted into the slide groove of the slider, so that the rotational motion of the transmission gear can be converted into axial reciprocating motion of the main shaft, characterized in that: the slider can be constrained on the main shaft by axial sliding relative to the main shaft, and a first elastic member acting on the slider is also provided to make the slider always have a tendency to move toward the tail end of the main shaft, and when the rocker arm rotates in the normal winding direction, the first elastic member can fix the slider relative to the main shaft.

[0006] In the above scheme, preferably, the first elastic member is a compression spring sleeved on the main shaft, one end of the compression spring abuts against the main shaft, and the other end abuts against the slider;

[0007] Alternatively, the first elastic member is a butterfly-shaped gasket sleeved on the main shaft and abutting against the sliding block.

[0008] In order to facilitate assembly and prevent the slider from being separated from the main shaft, the main shaft is also provided with a stopper abutting against the slider, and the stopper and the first elastic member are respectively located on both sides of the slider. At this time, the stopper can be a clamping ring clamped on the main shaft or a radial pin inserted on the main shaft.

[0009] In order to prevent the slider from rotating relative to the main shaft, the cross section of the local section where the main shaft and the slider match is designed to be a non-circular structure, and the slider is designed with a non-circular shaft hole that matches it.

[0010] In order to further improve the absorption of collapse energy under the action of external force, a further improvement is that the transmission gear includes a coaxially mounted first transmission wheel with the above-mentioned transmission teeth and a second transmission wheel with the above-mentioned eccentric column, and mutually meshing one-way teeth are provided on the opposite end faces of the first transmission wheel and the second transmission wheel, and a second elastic member is configured so that the one-way teeth on the first and second transmission wheels always have a tendency to mesh with each other, and the one-way teeth can allow the first transmission wheel and the second transmission wheel to mesh and rotate together with the winding direction of the rocker arm, and when external force forces the first transmission wheel to rotate against the winding direction, the one-way teeth can allow the first transmission wheel to rotate relative to the second transmission wheel.

[0011] In the above-mentioned improved solution, preferably, the second elastic member is a corrugated washer or a spring, which is arranged on the same side as the eccentric column and sleeved and limited on the shaft. The corrugated washer or the spring can better meet the elasticity required for the engagement or separation between the first transmission wheel and the second transmission wheel, and is easy to install.

[0012] In order to conveniently limit the above-mentioned corrugated gasket or spring, one end of the shaft is fixed to the inner wall of the shell, and the end of the other end is threadedly connected with a fastener that abuts against the corrugated gasket or spring.

[0013] In order to facilitate coaxial installation, a sleeve for the shaft to pass through is extended from the middle of the second transmission wheel toward the first transmission wheel, and the sleeve can pass through the shaft hole of the first transmission wheel.

[0014] In the above-mentioned improved scheme, it is further preferred that the meshing surface of each one-way tooth is composed of a radially distributed upright surface, an inclined surface arranged along the circumferential direction and gradually rising toward the upright surface side, and a plane connected between the top of the upright 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.

[0015] Compared with the prior art, since the slider of the present invention can slide axially relative to the main shaft and a first elastic member with suitable rigidity is cleverly added to the main shaft, during normal transmission and winding, the slider can still drive the main shaft to reciprocate axially through the first elastic member. Once they are subjected to an external force that causes them to rotate in the opposite direction of winding (such as generated by a collision), relative sliding will occur between the slider and the main shaft, so that the first elastic member will collapse and absorb energy.

[0016] In particular, the transmission gear is made into a split first transmission wheel and a second transmission wheel, and normal transmission is achieved by utilizing a structure in which the transmission teeth on the first transmission wheel mesh with the pinion gear and the eccentric column on the second transmission wheel cooperates with the slide groove on the slider. At the same time, with the help of the one-way teeth between the first transmission wheel and the second transmission wheel, the line-reeling function can be achieved by rotating together with the rocker arm during normal line-reeling. Once they are subjected to an external force that causes them to rotate in the opposite direction of line-reeling (such as that generated by a collision), the first transmission wheel and the second transmission wheel can rotate relative to each other, so that the external force is further absorbed by the relative rotation of the first transmission wheel and the second transmission wheel, thereby better protecting transmission components such as transmission gears and pinions.

[0017] Therefore, the present invention can effectively avoid damage to transmission parts such as transmission gears and pinions, thereby achieving the purpose of extending the service life of the fishing reel. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention is further described in detail below with reference to the accompanying drawings.

[0025] In the description of the following embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "axial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions 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 as "first" and "second" may explicitly or implicitly include one or more of such features.

[0026] like Figure 1 The figure shows a spinning reel, which includes a housing, a reel 10, a line housing 20 and an anti-collision transmission mechanism, wherein the housing includes a main body and a main cover fixed to the side of the tail of the main body by screws. Since the housing adopts the existing technology, in order to clearly see the anti-collision transmission mechanism inside, the housing is removed in each figure. The anti-collision transmission mechanism is located at the tail of the housing of the spinning reel, as shown in FIG. Figures 2 to 6As shown, it includes a pinion 1, a transmission gear 2, a main shaft 3, a slider 4 and an eccentric column 5, wherein the pinion 1 is installed on a mandrel 7 together with a toothed disc 6 as in the prior art, the mandrel 7 is supported on the above-mentioned main body and main cover through a bearing, and a rocker arm 8 is installed on one end of the mandrel 7, that is, by rotating the rocker arm 8, the mandrel 7 and the toothed disc 6 and the pinion 1 can be driven to rotate together. The circumference of the transmission gear is provided with a transmission tooth meshing with the pinion, and an eccentric column 5 is fixed on the end face of the transmission gear 2 facing the slider 4, and the end of the eccentric column is inserted into the slide groove 41 of the slider 4, and the slider 4 is arranged on the main shaft 3. The toothed disc 6 is located on one side of the gear rod 9 and meshes with the gear rod 9, the gear rod 9 is sleeved on the main shaft 3, and the gear rod 9 is supported in the main body through a bearing. The wire wheel 10 is installed on the main shaft 3, and the wire housing 20 is installed on the gear rod 9. When the rocker arm 8 is rotated, the wire wheel 10 can be driven to reciprocate along the axial direction of the main shaft 3 through the pinion 1, the transmission gear 2, the eccentric column 5, the slider 4, and the main shaft 3. At the same time, the wire housing 20 is driven to rotate through the toothed disc 6 and the gear rod 9. This transmission path is the same as the prior art and will not be described in detail.

[0027] In this embodiment, the main improvement is that the slider 4 can be constrained on the spindle 3 by axial sliding relative to the spindle 3 (that is, it is not fixed to the spindle by screws as in the prior art), and a first elastic member acting on the slider 4 is also configured. In the figure, the first elastic member is a compression spring 01 (a butterfly gasket can also be used) sleeved on the spindle 3, one end of the compression spring 01 abuts against the spindle (in the figure, there is a shoulder 31 on the spindle, one end of the compression spring 01 abuts against the shoulder 31, and a radially arranged limit pin can also be set on the spindle to replace the shoulder 31), and the other end abuts against the slider 4 so that the slider 4 always has a tendency to move toward the tail end of the spindle 3, and in order to prevent the slider 4 from detaching from the spindle 3, the tail of the spindle 3 is configured with a stopper abutting against one side of the slider 4, that is, the stopper and the compression spring 01 abut against the two sides of the slider respectively. Specifically, the stopper can be a clamping ring 02 clamped on the spindle 3 or a radial pin inserted on the spindle 3. Since the slider 4 and the main shaft 3 need to make axial reciprocating motion together during normal line reeling, the first elastic member needs to have a certain rigidity, that is, it needs to satisfy the requirement that when the rocker arm 8 rotates in the normal line reeling direction, the first elastic member can keep the slider 4 fixed relative to the main shaft 3, that is, the slider 4 needs to be tightly abutted against the stopper. Once impacted by external force, the external force makes the transmission gear and other transmission parts have a tendency to rotate against the line reeling direction. At this time, the slider 4 overcomes the force of the first elastic member and can move axially on the main shaft 3, so that the first elastic member is compressed and absorbs energy, thereby effectively protecting the transmission gear, pinion and other transmission parts from damage.

[0028] In the working process, in order to prevent the slider 4 from rotating relative to the main shaft 3, the cross section of the local section where the main shaft 3 and the slider 4 cooperate is designed to be a non-circular structure, and the slider 4 is designed with a non-circular shaft hole 42 corresponding thereto. The non-circular structure can be a polygonal structure. In the figure, a flat shaft structure is formed by machining a plane 32 on the main shaft. Of course, the slider 4 and the main shaft 3 can also be connected together through a keyway structure to achieve relative axial sliding when necessary, while being fixed together in the circumferential direction.

[0029] In order to further absorb the force of external force, in this embodiment, further improvement is made, that is, the above-mentioned transmission gear 2 is designed to be a split structure, and the transmission gear includes a first transmission wheel 21 and a second transmission wheel 22 installed coaxially 03. The periphery of the first transmission wheel 21 is provided with transmission teeth meshing with the pinion 1, and the above-mentioned eccentric column 5 is arranged 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. At the same time, mutually meshing one-way teeth 23 are provided on the opposite end faces of the first transmission wheel 21 and the second transmission wheel 22, and a second elastic member 04 is configured. Specifically, the second elastic member can be a corrugated gasket (or a spring), which is arranged and sleeved on the same side as the eccentric column and limited on the shaft 03. In the figure, one end of the shaft 03 is fixed to the inner wall of the main body, and the end of the other end is threadedly connected with a fastener 05 that abuts against the corrugated gasket (or spring). The fastener 05 can be a bolt. In this case, a screw hole is opened at the other end of the shaft 03. Of course, the fastener can also be a nut. In this case, the other end of the shaft is designed as a screw rod, and the nut is threadedly connected to the screw rod to achieve the purpose of tightening the corrugated gasket (or spring), thereby allowing the corrugated gasket (or spring) to press 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.

[0030] Considering the convenience of assembly and the reliability of transmission, a sleeve 221 for the shaft 03 to pass through is extended from the middle of the second transmission wheel 22 toward the first transmission wheel side, and the sleeve 221 can pass through the shaft hole 211 of the first transmission wheel 21 .

[0031] The above-mentioned one-way teeth 23 are set to meet the following conditions: it can allow the above-mentioned first transmission wheel 21 and the second transmission wheel 22 to mesh and rotate together with the winding direction of the rocker arm, so as to realize the normal winding function; and when the external force forces the first transmission wheel 21 to rotate against the winding direction, the one-way teeth 23 can allow the first transmission wheel 21 to rotate relative to the second transmission wheel 22. In this process, the first transmission wheel 21 needs to overcome the force of the second elastic member 04. Preferably, the meshing surface of the one-way teeth 23 is composed of a radially distributed vertical surface 231, a circumferentially arranged inclined surface 232 gradually rising toward the vertical surface side, and a plane 233 connected between the top of the vertical surface and the top of the inclined surface, and adjacent one-way teeth have a connecting surface 234 meshing with the plane on the corresponding one-way teeth. In this way, during normal transmission, the vertical surfaces 231 on the corresponding one-way teeth 23 mesh with each other, so that the first transmission wheel 21 and the second transmission wheel 22 can rotate together in only one direction. When subjected to reverse force, due to the inclined surface fit, the first transmission wheel 21 will overcome the force of the second elastic member 04, climb the slope and rotate relative to the second transmission wheel 22, that is, slippage will occur between the two, thereby absorbing the impact force of the external force, achieving the purpose of collapse and energy absorption, avoiding damage to the components in the transmission mechanism due to large impact force, and ensuring that the spinning fishing reel can still work normally after the impact.
