Description

Technical Field

[0001] This invention belongs to the field of fishing gear technology and relates to a spinning reel with a fixed spindle. Background Technology

[0002] A fishing reel is an accessory component of a fishing rod, and it is increasingly widely used by anglers in modern fishing activities. During the retrieval process, the reel is driven by a spool, which rotates the reel holder and causes the spool to move back and forth, thus retrieving the line from the spool. When retrieving the line, the handle is turned to rotate the reel holder, and the extended pin on the reel holder catches the fishing line and rotates around the reel to complete the retrieval. During the retrieval process, in order to ensure that the fishing line is wound more evenly onto the spool, the reel will move back and forth along the main axis.

[0003] Traditional fishing reel structures primarily utilize a cam-driven mechanism (e.g., Chinese invention patent CN201921690560.9, "A Fishing Reel") to achieve the reciprocating motion of the spindle, which in turn drives the spool to reciprocate. While this traditional structure can achieve the reciprocating motion of the spool, it also has certain structural drawbacks:

[0004] 1. In this transmission structure, the main shaft in the fishing reel is a moving component. In order to ensure that the main shaft can achieve the effect of movement, when the main shaft moves to the position furthest from the winding frame, the strength of the main shaft decreases and it will bend and deform together with the reel.

[0005] 2. When using a cam drive structure, the stroke of the spool is generally determined by the size of the gear (transmission component). When a larger stroke is required, the diameter of the gear also needs to be increased accordingly. This results in the volume of the tail of the fishing reel, i.e. the spool, increasing, making the overall appearance of the tail of the fishing reel appear bulky.

[0006] 3. When using a cam drive structure, the speed ratio between the rocker wheel and the spool is small, which causes the reciprocating speed of the spool to be too fast during the winding process, resulting in an unsatisfactory winding effect. Summary of the Invention

[0007] To solve the implementation technical problems, the present invention adopts the following technical solution:

[0008] A spinning reel with a fixed spindle includes: a take-up frame, a rocker drive unit, a spool, and a spindle; the spindle is provided with a drive assembly, a differential assembly, and a transmission assembly arranged sequentially from front to back.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] This invention provides reference to [the relevant document]. Figures 1-2 In this embodiment of the invention, a spinning reel with a fixed main shaft 4 includes: a take-up frame 2, a rocker drive unit 3, a winding spool 1, and a main shaft 4; the main shaft 4 is provided with a drive assembly 5, a differential assembly 6, and a transmission assembly 7 arranged sequentially from front to back.

[0051] The take-up frame 2 is nested on the transmission rack 52 and can rotate around the main shaft 4;

[0052] The rocker drive unit 3 and the winding spool 1 are respectively located at the front and rear ends of the take-up frame 2; the rocker drive unit 3 and the take-up frame 2 are connected by a drive assembly 5, which can drive the drive assembly 5 to rotate the take-up frame around the main shaft 4 by rocking the rocker drive unit 3.

[0053] The take-up frame 2 and the transmission assembly 7 are connected by a differential transmission assembly 6. During the rotation of the take-up frame 2, the differential transmission assembly 6 will simultaneously drive the transmission assembly 7 to rotate. The differential transmission assembly 6 achieves a large differential speed ratio between the take-up frame 2 and the transmission assembly 7, thereby reducing the speed of the transmission assembly 7.

[0054] The transmission component 7 is in transmission cooperation with the winding spool 1. The transmission component 7 can rotate inside the winding spool 1, thereby driving the winding spool 1 to reciprocate along the axial direction of the main shaft 4. In specific implementation, the rocker drive unit 3 is used to drive the take-up frame 2 to rotate while the main shaft 4 is fixed, and drive the winding spool 1 to reciprocate along the main shaft 4, so as to achieve the working effect of fishing reel take-up.

[0055] This application provides two transmission embodiments under a fixed spindle 4 structure; the two embodiments can respectively achieve the effects of lightweight transmission structure and high strength and better stability of transmission structure.

[0056] In both embodiments, the drive assembly 5 has the same structure, including: a transmission rack 52 and a hypoid gear 51;

[0057] Among them, the quasi-hyperboloid gear 51 is disposed in the rocker drive unit 3 and is coaxially engaged with the rocker arm 31 in the rocker drive unit 3;

[0058] The beginning of the transmission rack 52 is a helical tooth that meshes with the hypoid gear 51. The transmission rack 52 can be driven to rotate through the rocker wheel drive unit 3. The take-up frame 2 is nested at the end of the transmission rack 52 to realize the transmission cooperation between the rocker wheel drive unit 3 and the take-up frame 2. When working, the rotation of the take-up frame 2 can be achieved by rocking the rocker wheel of the rocker wheel drive unit 3.

[0059] Example 1:

[0060] like Figure 2-5 As shown, this embodiment is an example of a lightweight transmission structure, wherein the differential assembly 6 includes: a first speed regulating gear 61, a first transmission gear 63, and a drive gear sleeve 62.

[0061] The drive sleeve 62 is mounted on the take-up frame 2 and can rotate synchronously with it. The main shaft 4 passes through the drive sleeve 62. The first speed regulating gear 61 and the first transmission gear 63 are nested on the main shaft 4 and located within the drive sleeve 62. The first speed regulating gear 61 is fixed to the main shaft 4 by a pin. The first speed regulating gear 61 and the first transmission gear 63 mesh with the drive sleeve 62 in a non-coaxial manner, and the number of teeth of the first speed regulating gear 61 is not equal to the number of teeth of the first transmission gear 63. For example, the number of teeth of the first speed regulating gear 61 is one less than the number of teeth of the first transmission gear 63. During the rotation of the take-up frame 2, the drive sleeve 62 will rotate around the first speed regulating gear 61 and the first transmission gear 63. When the drive sleeve 62 rotates, the first speed regulating gear 61 and the first transmission gear 63 mesh together. Due to the difference in the number of teeth on the first transmission gear 63, the first speed regulating gear 61 and the first transmission gear 63 will be misaligned at a certain tooth position. When the drive sleeve 62 moves to the misaligned tooth position, it will drive the first transmission gear 63 and the first speed regulating gear 61 to align the misaligned teeth at that position. Since the first speed regulating gear 61 is a fixed gear structure, the first transmission gear 63 will rotate by one tooth under the drive sleeve 62, resulting in the first transmission gear 63 rotating relative to the first speed regulating gear 61. During continuous take-up, the take-up frame 2 rotates approximately one revolution, which will drive the first transmission gear 63 to rotate by one tooth position. The rotation of the first transmission gear 63 will drive the transmission component 7 to rotate. This achieves a large differential speed ratio transmission between the take-up frame 2 and the transmission component 7.

[0062] In this embodiment, the transmission component 7 includes a rotating sleeve 72 and a first movable guide block 71 that slides with the rotating sleeve 72. The rotating sleeve 72 is mounted on the main shaft 4 and is connected to the first transmission gear 63, so that the rotating sleeve 72 can rotate under the drive of the first transmission gear 63 in the differential component 6.

[0063] The rotating sleeve 72 is formed with a sleeve double helix guide groove 721 arranged along its axial direction; the first moving guide block 71 is installed inside the winding spool 1, and the lower end of the first moving guide block 71 extends and is embedded in the sleeve double helix guide groove 721 of the rotating sleeve 72; during the rotation of the rotating sleeve 72, the first moving guide block 71 will slide along the sleeve double helix guide groove 721, driving the winding spool 1 to reciprocate along the axial direction of the main shaft 4.

[0064] Furthermore, the first movable guide block 71 is composed of a fixing screw sleeve 712, a first guide screw 711, and a first slider guide claw 713;

[0065] The fixing screw sleeve 712 is fixedly connected to the winding spool 1, and the fixing screw sleeve 712 is provided with a through threaded hole, and the first guide screw 711 is installed in the through threaded hole of the fixing screw sleeve 712;

[0066] The first slider guide claw 713 is located at the lower end of the first guide screw 711. The first slider guide claw 713 can rotate within the fixed screw sleeve 712. The lower end of the first slider guide claw 713 is embedded in the double helical guide groove 721 of the sleeve rod to slide within the helical groove. The lower end of the first slider guide claw 713 is an "n"-shaped clamping structure, which is clamped on the rotating sleeve rod 72.

[0067] The "n"-shaped clamping structure makes the fit between the first slider guide claw 713 and the sleeve double helix guide groove 721 more stable. During the movement of the first moving guide block 71 in the sleeve double helix guide groove 721, the first slider guide claw 713 will rotate at a specific angle, so that the first moving guide block 71 can reciprocate along the sleeve double helix guide groove 721.

[0068] Furthermore, in this embodiment, in order to better improve the stability of the spindle 4, a support sleeve 73 is also provided at the front end of the spindle 4;

[0069] The main shaft 4 is inserted into the support sleeve 73, and the rotating sleeve 72 is also set in the support sleeve 73; the front end of the main shaft 4 is fixedly installed in the support sleeve 73, and the support sleeve 73 provides front end support force for the main shaft 4; a support bearing is provided between the rear end of the support sleeve 73 and the rotating sleeve 72 to achieve the effect of rear end support of the support sleeve 73.

[0070] Furthermore, the support sleeve 73 is also formed with a sleeve slot 731 arranged along its length direction. The first moving guide block 71 in the transmission assembly 7 is arranged in the sleeve slot 731 and performs reciprocating motion along the sleeve slot 731.

[0071] Example 2:

[0072] like Figure 6-8 As shown, this embodiment is an embodiment with high strength characteristics of transmission structure, wherein the differential component 6 includes: a second speed regulating gear 66, a second transmission gear 65 and a drive gear 64;

[0073] The second speed regulating gear 66 and the second transmission gear 65 are nested on the main shaft 4, wherein the second speed regulating gear 66 is fixed on the main shaft 4 by a pin; and the number of teeth of the second speed regulating gear 66 is not equal to the number of teeth of the second transmission gear 65.

[0074] The drive gear 64 is mounted on the take-up frame 2 and meshes with the second speed regulating gear 66 and the second transmission gear 65. During the rotation of the take-up frame 2, the drive gear 64 will rotate around the second speed regulating gear 66 and the second transmission gear 65.

[0075] The differential component 6 in Embodiment 2 operates similarly to that in Embodiment 1: During the rotation of the take-up frame 2, the drive gear 64 rotates around the second speed-regulating gear 66 and the second transmission gear 65, following the take-up frame 2. When the drive gear 64 rotates, taking the example where the first speed-regulating gear 61 has one fewer tooth than the first transmission gear 63, the second speed-regulating gear 66 and the second transmission gear 65 will be misaligned at a certain tooth position. When the drive gear 64 reaches this misaligned tooth position, it will engage the second transmission gear 65. The teeth of the second speed regulating gear 66, which are offset from each other at this position, are aligned. Since the second speed regulating gear 66 is a fixed gear structure, the second transmission gear 65 will rotate one tooth distance under the drive gear 64, thus realizing the rotation of the second transmission gear 65 relative to the second speed regulating gear 66. During continuous take-up, the take-up frame 2 rotates approximately one revolution, which drives the second transmission gear 65 to rotate one tooth position. The rotation of the second transmission gear 65 will drive the transmission component 7 to rotate. This achieves a large differential speed ratio transmission between the take-up frame 2 and the transmission component 7.

[0076] The transmission component 7 in this embodiment includes: a rotating sleeve 76, a rotating guide seat 75, and a second moving guide block 74;

[0077] The front end of the main shaft 4 is formed with a double helical guide groove 42, and the rotating sleeve 76 is nested in the front end of the main shaft 4; the rotating sleeve 76 is connected and cooperates with the second transmission gear 65, and is driven to rotate through it.

[0078] The rotary guide seat 75 is nested on the rotary sleeve 76. When the rotary sleeve 76 rotates, the rotary guide seat 75 will rotate with the rotary sleeve 76.

[0079] The second moving guide block 74 is installed in the rotating guide seat 75, and the rotating sleeve 76 is formed with a guide groove 761 arranged along its length direction; the lower end of the second moving guide block 74 extends and is embedded in the spindle double helix guide groove 42 of the spindle 4;

[0080] During the rotation of the rotating sleeve 76, the groove wall of the guide groove 761 will contact the second moving guide block 74, thereby driving the rotating guide seat 75 to rotate. During the rotation of the rotating guide seat 75, the second moving guide block 74 will slide along the double helical guide groove 42 of the main shaft, so that the entire rotating sleeve 76 will reciprocate along the main shaft 4 in the axial direction. The rotating guide seat 75 is connected and engaged with the winding spool 1 in the axial direction. While the rotating sleeve 76 is reciprocating, the winding spool 1 will reciprocate along the axial direction of the main shaft 4.

[0081] Furthermore, the second moving guide block 74 is composed of a second guide screw 741 and a second slider guide claw 742;

[0082] The rotary guide seat 75 is provided with a through threaded hole, and the second guide screw 741 is installed in the through threaded hole of the rotary guide seat 75.

[0083] The second slider guide claw 742 is located at the lower end of the second guide screw 741. The second slider guide claw 742 can rotate within the second guide screw 741. The lower end of the second slider guide claw 742 is embedded in the double helical guide groove 42 of the main shaft to achieve sliding engagement. The lower end of the second slider guide claw 742 is an "n"-shaped clamping structure, which is clamped on the main shaft 4.

[0084] The "n"-shaped clamping structure makes the fit between the second slider guide claw 742 and the main shaft double helical guide groove 42 more stable. During the movement of the second moving guide block 74 in the main shaft double helical guide groove 42, the second slider guide claw 742 will rotate at a specific angle, so that the second moving guide block 74 can reciprocate along the main shaft double helical guide groove 42.

[0085] Furthermore, in this embodiment, in order to better improve the smoothness of the winding spool 1 during the reciprocating movement, a guide slide seat 763 is installed at the end of the main shaft 4, and guide slide bearings 761 are respectively installed at the upper and lower ends of the guide slide seat 763.

[0086] Furthermore, the inner shell of the winding spool 1 is formed with a guide groove 762 corresponding to the guide sliding bearing 761; the guide sliding bearing 761 extends into the guide groove 762 and contacts the side wall of the guide groove 762; during the reciprocating movement of the winding spool 1, the sliding bearing achieves the guiding sliding operation.
