Description

Technical Field

[0001] This utility model relates to the field of fishing reel technology, and in particular to a one-way waterproof structure for fishing reels. Background Technology

[0002] Fishing reels, also known as line reels or line feeders, are essential equipment in fishing for reeling in and out fishing lines. The waterproof structure of fishing reels is a key design feature that improves their durability and lifespan. Especially in sea fishing or humid environments, good waterproof performance can effectively prevent seawater, sand, and other substances from corroding internal parts.

[0003] There is a gap between the spool and the connecting drum of the fishing reel. A waterproof structure is needed to provide an auxiliary seal between the spool and the connecting drum to achieve the purpose of waterproofing. The existing waterproof structure mainly uses a sealing ring to seal the inside of the spool and the connecting drum. However, the sealing ring is subject to strong compressive force between the metal structures, which may shrink or even break, thus causing the waterproof performance of the waterproof structure to deteriorate and requiring constant replacement. Utility Model Content

[0004] This invention addresses the problem that existing waterproof structures primarily rely on sealing rings to seal the inside of the spool and connecting cylinder. However, these sealing rings are subject to strong compressive forces between the metal structures, which may cause them to shrink or even break, leading to a decrease in the waterproof performance of the structure. Therefore, this invention proposes a one-way waterproof structure for fishing reels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a one-way waterproof structure for fishing reels, comprising an airbag disposed on the outer surface of the connection between the spool and the connecting cylinder, wherein an auxiliary device is disposed on one side of the airbag, and the auxiliary device seals the connection between the connecting cylinder and the spool by providing an air cavity connected to the inner wall of the airbag and pushing the gas in the air cavity into the airbag to cause the airbag to expand and deform.

[0006] The effect achieved by the above components is as follows: by setting an airbag instead of a sealing ring to seal between the spool and the connecting tube, the airbag itself has good deformation capability, and the deformation of the airbag can be controlled and adjusted by the volume of gas entering the airbag. Moreover, the airbag is placed on the outer surface of the spool and the connecting tube and will not be squeezed, thus greatly extending the service life of the waterproof structure, enabling the waterproof structure to provide a one-way waterproof seal for the spool and the connecting tube for a long time.

[0007] Preferably, the auxiliary device includes an air chamber, the inner wall of which is connected to the inner wall of the air bag. The air chamber is fixedly installed on the outer surface of the connecting cylinder. A ring is slidably installed on the inner wall of the air chamber. Four round rods are evenly fixedly installed on one side of the ring. The outer surfaces of the round rods are slidably installed on the inner wall of the air chamber. One end of each of the four round rods passes through the inner wall of the air chamber and is fixedly installed with the same auxiliary ring. The auxiliary ring is slidably installed on the outer surface of the connecting cylinder.

[0008] The effect achieved by the above components is as follows: the auxiliary ring is pushed to slide on the outer surface of the connecting cylinder, the auxiliary ring will drive the four round rods to slide on the inner wall of the air chamber, the four round rods will drive the ring to slide on the inner wall of the air chamber, and will push the gas into the air bag. After the gas enters the air bag, it will cause the air bag to expand and deform, and then the air bag can provide auxiliary sealing at the connection between the connecting ring and the spool.

[0009] Preferably, the air cavity is made of resin material with poor deformation ability, and the air bag is made of rubber material with good deformation ability.

[0010] The effects achieved by the above components are as follows: poor air cavity deformation capability helps to prevent the air cavity from deforming when the ring slides on the inner wall of the air cavity, which would cause gaps between the ring and the air cavity, making it impossible for the airbag to expand. On the other hand, the airbag has good deformation capability, which not only facilitates the expansion of the airbag, but also enables the airbag to provide a good sealing effect between the connecting cylinder and the spool.

[0011] Preferably, rubber rings are bonded to both the outer and inner sides of the ring, and the outer surfaces of both rubber rings abut against the inner wall of the air cavity.

[0012] The effect achieved by the above-mentioned components is that by setting the rubber ring, the space between the ring and the air chamber can be further sealed, improving the airtightness between the airbag and the ring and preventing the airbag from leaking.

[0013] Preferably, a spring is fitted on the outer surface of the ring, and the two ends of the spring are respectively fixedly installed on one side of the auxiliary ring and the air chamber.

[0014] The effect achieved by the above components is as follows: by setting a spring, the spring will pull the auxiliary ring without being affected by other external forces, which in turn can push the round rod and the round ring, which helps to prevent the gas in the airbag from flowing into the air chamber.

[0015] Preferably, a fixing component is further provided between the auxiliary ring and the air chamber. The fixing component includes a slot block, one side of which is fixedly installed on the outer surface of the auxiliary ring. A threaded pin is inserted into the inner wall of the slot block, one end of which is fixedly installed on the outer surface of the air chamber, and a nut is threaded onto the outer surface of the threaded pin.

[0016] The effect achieved by the above components is as follows: when the auxiliary ring is adjusted to the appropriate position, the nut is rotated so that one side of the nut presses against the slot block, thereby making the slot block abut against the outer surface of the air chamber, which can fix the auxiliary ring and help prevent the auxiliary ring from causing the ring to shift and causing the airbag to deflate.

[0017] Preferably, a rubber ring is bonded to the outer surface of the air cavity, one side of the slot block abuts against the outer surface of the rubber ring, and the threaded pin is inserted into the inner wall of the rubber ring.

[0018] The effect achieved by the above components is as follows: by setting a rubber ring, the outer surface of the air chamber is brought into contact with one side of the slot block, which increases the friction between the slot block and the air chamber, making the fixation of the auxiliary ring more stable.

[0019] Preferably, a circular block is fixedly installed at one end of the threaded pin, and the outer diameter of the circular block is larger than the outer diameter of the threaded pin.

[0020] The effect achieved by the above components is that the circular block can block one end of the threaded pin, which helps to prevent the nut from coming off the threaded pin.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, an airbag is used to replace the sealing ring to seal between the spool and the connecting tube. The airbag itself has good deformation capability, and the deformation of the airbag can be controlled and adjusted by the volume of gas entering the airbag. Moreover, the airbag is placed on the outer surface of the spool and the connecting tube and will not be squeezed, thus greatly extending the service life of the waterproof structure. This allows the waterproof structure to provide a one-way sealing and waterproof function for the spool and the connecting tube for a long time. Attached Figure Description

[0024] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a one-way waterproof structure for a fishing reel, including an airbag 1 disposed on the outer surface of the connection between the spool 6 and the connecting cylinder 5. An auxiliary device 2 is disposed on one side of the airbag 1. The auxiliary device 2 seals the connection between the connecting cylinder 5 and the spool 6 by providing an air cavity 21 connected to the inner wall of the airbag 1 and pushing the gas in the air cavity 21 into the airbag 1, causing the airbag 1 to expand and deform. The fishing reel includes a fishing reel body 4, a connecting cylinder 5, and a spool 6. The connecting cylinder is installed on one side of the fishing reel body 1. The spool 6 is installed on the inner wall of the fishing reel body 1. An air bladder 1 is used to seal the spool 6 and the connecting cylinder 5 instead of a sealing ring. The air bladder 1 itself has good deformation capability, and the deformation of the air bladder 1 can be controlled and adjusted by the volume of gas entering the air bladder 1. Moreover, the air bladder 1 is placed on the outer surface of the spool 6 and the connecting cylinder 5 and will not be squeezed, which greatly extends the service life of the waterproof structure. This allows the waterproof structure to provide a one-way waterproof seal for the spool 6 and the connecting cylinder 5 for a long time.

[0025] Reference Figure 2 and Figure 3As shown, the auxiliary device 2 includes an air chamber 21. The inner wall of the air chamber 21 is connected to the inner wall of the airbag 1. The air chamber 21 is fixedly installed on the outer surface of the connecting cylinder 5. A ring 22 is slidably installed on the inner wall of the air chamber 21. Four round rods 23 are evenly fixedly installed on one side of the ring 22. The outer surfaces of the round rods 23 are slidably installed on the inner wall of the air chamber 21. One end of each of the four round rods 23 passes through the inner wall of the air chamber 21 and is fixedly installed with the same auxiliary ring 24. The auxiliary ring 24 is slidably installed on the outer surface of the connecting cylinder 5. Pushing the auxiliary ring 24 to slide on the outer surface of the connecting cylinder 5 will cause the four round rods 23 to slide on the inner wall of the air chamber 21. The four round rods 23 will cause the ring 22 to slide on the inner wall of the air chamber 21. The inner wall of the air chamber 1 slides, pushing the gas into the air chamber 1. After the gas enters the air chamber 1, it will cause the air chamber 1 to expand and deform, thereby providing an auxiliary seal at the connection between the connecting ring and the spool 6. The air chamber 21 is made of resin material with poor deformation ability, while the air chamber 1 is made of rubber material with good deformation ability. The poor deformation ability of the air chamber 21 helps to prevent the air chamber 21 from deforming when the ring 22 slides on the inner wall of the air chamber 21, which would cause a gap between the ring 22 and the air chamber 21, preventing the air chamber 1 from expanding. The good deformation ability of the air chamber 1 not only facilitates the expansion of the air chamber 1, but also enables the air chamber 1 to provide a good sealing effect between the connecting cylinder 5 and the spool 6.

[0026] Reference Figure 2 and Figure 3 As shown, rubber rings 25 are bonded to both the outer and inner sides of the ring 22. The outer surfaces of both rubber rings 25 abut against the inner wall of the air cavity 21. By setting the rubber rings 25, the ring 22 and the air cavity 21 can be further sealed, improving the airtightness between the airbag 1 and the ring 22 and preventing the airbag 1 from leaking. A spring 26 is sleeved on the outer surface of the ring 22. The two ends of the spring 26 are fixedly installed on one side of the auxiliary ring 24 and the air cavity 21, respectively. By setting the spring 26, the spring 26 will pull the auxiliary ring 24 without the influence of other external forces, which in turn can push the rod 23 and the ring 22, which helps to prevent the gas in the airbag 1 from flowing into the air cavity 21.

[0027] Reference Figure 4 and Figure 5As shown, a fixing component 3 is also provided between the auxiliary ring 24 and the air chamber 21. The fixing component 3 includes a slot block 31. One side of the slot block 31 is fixedly installed on the outer surface of the auxiliary ring 24. A threaded pin 32 is inserted into the inner wall of the slot block 31. One end of the threaded pin 32 is fixedly installed on the outer surface of the air chamber 21. A nut 33 is threadedly connected to the outer surface of the threaded pin 32. When the auxiliary ring 24 is adjusted to a suitable position, the nut 33 is rotated, so that one side of the nut 33 presses against the slot block 31, thereby causing the slot block 31 to abut against the outer surface of the air chamber 21, thus fixing the auxiliary ring 24. This helps to prevent the auxiliary ring 24 from causing the ring 22 to shift and causing the airbag 1 to deflate.

[0028] Reference Figure 4 and Figure 5 As shown, a rubber ring 34 is bonded to the outer surface of the air cavity 21. One side of the slot block 31 abuts against the outer surface of the rubber ring 34. The threaded pin 32 is inserted into the inner wall of the rubber ring 34. By setting the rubber ring 34, the outer surface of the air cavity 21 abuts against one side of the slot block 31, which increases the friction between the slot block 31 and the air cavity 21, making the fixation of the auxiliary ring 24 more stable. A round block 35 is fixedly installed at one end of the threaded pin 32. The outer diameter of the round block 35 is larger than the outer diameter of the threaded pin 32. The round block 35 can block one end of the threaded pin 32, which helps to prevent the nut 33 from dislodging from the threaded pin 32.

[0029] Working principle: The auxiliary ring 24 slides on the outer surface of the connecting cylinder 5, which in turn drives the four round rods 23 to slide on the inner wall of the air chamber 21. The four round rods 23 then drive the ring 22 to slide on the inner wall of the air chamber 21, pushing gas into the airbag 1. Once the gas enters the airbag 1, it causes the airbag 1 to expand and deform, thus providing an auxiliary seal at the connection between the connecting ring and the spool 6. The rubber ring 25 further seals the connection between the ring 22 and the air chamber 21, improving the seal between the airbag 1 and the ring. The airtightness between 22 prevents airbag 1 from leaking. Spring 26 also pulls on auxiliary ring 24, which in turn pushes round rod 23 and ring 22, which helps prevent gas in airbag 1 from flowing into air chamber 21. Then, rotate nut 33 so that one side of nut 33 presses against slot block 31, which in turn makes slot block 31 abut against rubber ring 34 on the outer surface of air chamber 21, thus fixing auxiliary ring 24 and preventing auxiliary ring 24 from causing ring 22 to shift and causing airbag 1 to deflate.
