Description

Technical Field

[0001] This invention relates to fishing equipment, and in particular to a waterproof structure for a spinning reel. Background Technology

[0002] A typical spinning reel has a housing, a handle on the side of the housing, a spool at the front of the housing, and a rotor assembly between the housing and the spool. When the user rotates the handle, the rotor assembly is driven to rotate, thus winding the fishing line onto the spool. To protect the internal parts of the housing from moisture or salt corrosion, a waterproof gasket is usually placed between the housing and the rotor assembly. However, because the waterproof gasket is located between the stationary housing and the rotating rotor assembly, friction is inevitably generated, affecting the smoothness of the reel's operation, thus requiring improvement. Summary of the Invention

[0003] One objective of this invention is to provide a waterproof structure for a spinning wheel type reel, which can reduce the friction between the rotor assembly and the housing, and improve the smoothness of use.

[0004] To achieve the above objectives, the waterproof structure of the spinning wheel type reel of the present invention includes a housing, a worm gear, a bushing, a waterproof bearing, a cover, a rotor assembly, an outer washer, and an inner washer; the housing has a chamber, an opening located at the front end of the chamber, and an rim surrounding the opening; the worm gear is located in the chamber and extends forward out of the opening; the bushing is fitted onto the worm gear; the waterproof bearing has a first outer ring abutting against the housing, and a first inner ring fitted onto the bushing; the cover... A plate portion is disposed on the housing, and a through hole connects the chamber to the outside. The plate portion abuts against the first outer ring of the waterproof bearing. A rotor assembly is disposed at one outer end of the worm gear, and the rotor assembly is driven to rotate by the worm gear. The rotor assembly has abutting top abutting against the bushing. An outer washer is fitted onto the first outer ring of the waterproof bearing and sandwiched between the plate portion of the cover and the edge of the housing. An inner washer is fitted onto the bushing and sandwiched between the abutting top of the rotor assembly and the first inner ring of the waterproof bearing. In this way, the spinning wheel type winder can reduce the friction between the rotor assembly and the housing, and improve the smoothness of use. Attached Figure Description

[0031] The following describes the technical content and features of the present invention in detail with reference to four preferred embodiments and accompanying drawings. Figures 1-3 The diagram shows a waterproof structure of a spinning wheel type reel 1 provided in a preferred embodiment of the present invention, comprising a housing 10, a handle 15, a worm gear 16, a one-way bearing 20, a bushing 25, a waterproof bearing 30, a cover 35, a rotor assembly 40, an outer washer 48, an inner washer 49, and a reel 50. For ease of explanation, this document uses... Figure 1 Arrow A points in the direction of forward, and the opposite direction points in the direction of backward, but such directions should not be used to limit the scope of the patent in this case.

[0032] The housing 10 has a chamber 11 for accommodating components such as a transmission mechanism (not shown), a circular opening 12 located at the front end of the chamber 11, an annular rim 13 surrounding the opening 12, and a stepped annular stop 14 located inside the chamber 11.

[0033] The handle 15 is located on one side of the housing 10 and is connected to the transmission mechanism.

[0034] The worm 16 is located within the chamber 11 and extends forward from the opening 12. The rear section of the worm 16 is connected to the transmission mechanism. When the handle 15 is rotated, the worm 16 can be rotated through the transmission mechanism. The outer edge of the middle section of the worm 16 has two parallel cut surfaces 17, which allow the rotational power of the worm 16 to be transmitted to the rotor assembly 40 (described later). However, in other embodiments, the number of cut surfaces 17 may be only one, or the cross-section of the middle section of the worm 16 may be non-circular.

[0035] The one-way bearing 20 has a second outer ring 21 that abuts against the housing 10, a second inner ring 22 that is sleeved on the worm 16 and abuts against the bushing 25, and a plurality of rolling elements 23 disposed between the second outer ring 21 and the second inner ring 22. The inner edge of the second inner ring 22 has two flat portions 23 that abut against the two cut surfaces 17 of the worm 16, so that the second inner ring 22 can rotate with the worm 16. In this way, the one-way bearing 20 can restrict the worm 16 to rotate only in one direction.

[0036] The bushing 25 has a circular tube 26 fitted onto the worm gear 16, and a flange 28 extending radially outward from the inner end of the tube 26.

[0037] The waterproof bearing 30 has a first outer ring 31 that abuts against the housing 10 and its stop portion 14, a first inner ring 32 that is sleeved on the tube portion 26 of the bushing 25 and abuts against the retaining flange 28, and a plurality of balls (not shown) disposed between the first outer ring 31 and the first inner ring 32. The first inner ring 32 is confined between the retaining flange 28 and the inner washer 49. The waterproof bearing 30 can prevent liquid water from passing through the space between the first outer ring 31 and the first inner ring 32.

[0038] The cover 35 has a plate portion 36 which is attached to the housing 10 by three bolts 37, a through hole 38 connecting the chamber 11 to the outside, and a cover tube 39 extending inward from the plate portion 36. The plate portion 36 abuts against the rim 13 and the first outer ring 31 of the waterproof bearing 30, so that the first outer ring 31 is confined between the plate portion 36 and the stop portion 14.

[0039] The rotor assembly 40 is located at an outer end 18 of the worm 16. The rotor assembly 40 can be driven to rotate by the worm 16. The rotor assembly 40 has a top 41 that abuts against the bushing 25. Specifically, the rotor assembly 40 includes a reel housing 42, a washer 45, and a front washer 47. The reel housing 42 has an inner tube 43. The washer 45 is sandwiched between the inner tube 43 and the tube portion 26 of the bushing 25. The inner tube 43 has a shaft hole 44 whose shape corresponds to the outer edge of the middle section of the worm 16. The washer 45 has a shaft hole 46 whose shape also corresponds to the outer edge of the middle section of the worm 16, so that the reel housing 42 and the washer 45 can rotate together with the worm 16. In this way, the reel housing 42 can be driven by the handle 15 to wind the fishing line (not shown) onto the reel 50. In this embodiment, the gasket 45 forms the top 41, and the front washer 47 is fitted onto the inner tube 43 and abuts against the gasket 45, which can prevent water or moisture from entering the gap between the inner tube 43 and the gasket 45, thus achieving the effect of waterproofing. In order to securely position the front washer 47, the outer edge of the inner tube 43 may be provided with an outer concave ring 431 for the front washer 47 to be fitted.

[0040] The outer washer 48 is fitted onto the first outer ring 31 of the waterproof bearing 30 and sandwiched between the plate portion 36 of the cover 35 and the edge 13 of the housing 10, thereby preventing water or moisture from entering the gap between the housing 10 and the first outer ring 31, achieving a waterproof effect. To securely position the outer washer 48, a recess 131 can be provided on the edge 13 of the housing 10 for accommodating the outer washer 48.

[0041] The inner washer 49 is fitted onto the bushing 25 and sandwiched between the top 41 of the rotor assembly 40 and the first inner ring 32 of the waterproof bearing 30, thereby preventing water or moisture from entering the gap between the bushing 25 and the washer 45, and also preventing water or moisture from entering the gap between the bushing 25 and the first inner ring 32, thus achieving the effect of waterproofing.

[0042] When the handle 15 is rotated, the worm gear 16 can be rotated through the transmission mechanism. At this time, the bushing 25, the first inner ring 32 of the waterproof bearing 30, the inner washer 49, the gasket 45, the front washer 47, and the reel housing 42 rotate together with the worm gear 16. Conversely, the outer washer 48, the housing 10, the cover 35, and the first outer ring 31 of the waterproof bearing 30 remain fixed. In other words, the front washer 47, the outer washer 48, and the inner washer 49 do not move relative to adjacent components, thus eliminating friction. The friction between the rotor assembly 40 and the housing 10 comes only from the waterproof bearing 30 and the one-way bearing 20, effectively reducing friction between the rotor assembly 40 and the housing 10 and improving the smoothness of the spinning wheel type reel in operation. It also provides waterproofing against water intrusion into the housing 10, thereby achieving the purpose of this invention.

[0043] Based on the design spirit of this invention, the waterproof structure of the spinning wheel type reel 1 can be varied in other ways, such as... Figure 4 The diagram shows the waterproof structure of the spinning wheel type reel provided in the second preferred embodiment of the present invention. Its structure is largely the same as that of the first embodiment, except that the rotor assembly 40 omits the gasket 45 and the front washer 47. The inner end 432 of the inner tube 43 of the reel housing 42 forms the abutment 41 and abuts against the bushing 25. The inner washer 49 is sleeved on the bushing 25 and sandwiched between the abutment 41 and the first inner ring 32 of the waterproof bearing 30, thereby preventing water or moisture from entering the gap between the bushing 25 and the inner tube 43, and also preventing water or moisture from entering the gap between the bushing 25 and the first inner ring 32, thus achieving the waterproof effect.

[0044] For example Figure 5 The image shows the waterproof structure of the spinning wheel type reel provided in the third preferred embodiment of the present invention. Its structure is largely the same as the second embodiment, except that the inner end 432 of the inner tube 43 has a concave ring 433 for partially accommodating the bushing 25 and the inner washer 49, thus allowing the inner washer 49 to be more securely positioned. Alternatively, as shown... Figure 6 The diagram shows the waterproof structure of the spinning wheel type reel provided in the fourth preferred embodiment of the present invention. Its structure is largely the same as that of the first embodiment, except that it also includes a support ring 52 sleeved on the worm gear 16 and sandwiched between the retaining flange 28 of the bushing 25 and the second outer ring 21 of the one-way bearing 20. In this way, the support ring 52 can assist the first inner ring 32 and the bushing 25 in bearing the force toward the interior (i.e., backward) of the chamber 11, thereby reducing the deformation of the waterproof bearing 30 and the inner washer 49 and extending the service life of the waterproof bearing 30 and the inner washer 49.

[0045] Furthermore, the stop portion 14 of the housing 10 may be omitted, and all such easily conceivable structural changes should be covered by the scope of the present invention.
