Reel check valve balance protection mechanism

Abstract

This invention provides a reel check balance protection mechanism for the field of reels. [Solution] The reel check-stop balance protection mechanism includes a body, a base screw-connected to the body's cavity, a central shaft 3 rotating within the base's cavity, a movable lock 4 fitted onto the surface of the central shaft, and a limiting mechanism provided within the body's cavity. The intermeshing of the spline shaft 601 and ratchet 604 of the limiting mechanism makes it less likely for the central shaft to be obstructed when it rotates forward, while when the central shaft rotates backward, the spline shaft rotates the ratchet and body, and the screw connection between the body and the base moves the body and the movable lock. In other words, the rotation of the central shaft can be restricted by the screw and frictional force, and the reverse rotation of the reel can be effectively restricted when the reel body rotates backward. Furthermore, while performing the limiting function, it does not require drilling holes in the reel body and can improve the balance of the reel during use.

Description

Technical Field

[0001] The present invention relates to the field of reels, and specifically to a reel backstop balance protection mechanism.

Background Art

[0002] In the field of fishing, a "reel" (usually called a fishing line reel or a spool) is an important device attached to a fishing rod for storing fishing lines, and is particularly common in casting, sea fishing, or lure fishing. In the actual use scenario of the reel, backstop and balance of the body are extremely important for its normal operation. If the backstop assembly fails, the reel cannot operate normally, which has a profound impact on the user experience and efficiency. In addition, if high-speed reverse rotation or imbalance occurs during the use of the reel, it is likely to cause damage to the reel, not only reducing the service life of the reel, but also affecting the user experience.

[0003] In the prior art, in order to prevent the reverse rotation of the reel, usually, holes need to be drilled in the body of the reel and a backstop structure needs to be further attached, which can effectively improve the problem of reel reverse rotation prevention. However, the method of drilling holes is likely to destroy the integrity of the existing mechanism of the reel body, and during long-term use, it is likely to cause other failures due to changes in the body structure. Generally, problems occur in the internal structure of the body, so the repair difficulty is greatly improved, and the complexity during repair and the repair cost increase.

Summary of the Invention

[0004] To compensate for the deficiencies of the prior art, the method of drilling holes is likely to destroy the integrity of the existing mechanism of the reel body, and during long-term use, it is likely to cause other failures due to changes in the body structure. Generally, problems occur in the internal structure of the body, so there are problems such as greatly improved repair difficulty, increased complexity during repair, and increased repair cost. The present invention proposes a reel backstop balance protection mechanism.

[0005] The present invention employs a technical solution to solve the technical problem, which is a reel check balance protection mechanism, comprising a body, a base screw-connected to the cavity of the body, a central shaft rotating within the cavity of the base, a movement lock fitted onto the surface of the central shaft, and a limiting mechanism provided within the cavity of the body. The limiting mechanism includes a spline shaft, one end of which is fixedly connected to one end of a central shaft, a mounting block fixedly connected to the cavity of the body, a rotating lever rotatably connected to one side of the mounting block, a ratchet fixedly connected to the surface of the rotating lever, a return spring fixedly connected to the cavity of the body, one end of which is fixedly connected to the surface of the ratchet, the surface of which is which engages with the surface of the spline shaft, a return spring fixedly connected to the cavity of the base, and one end of which is fixedly connected to one side of the movement lock, in a reel check balance protection mechanism.

[0006] Preferably, a second screw groove is provided on the surface of the base, a first screw groove is provided on the surface of the central shaft, and an anti-slip layer is movably bonded to the surface of the body.

[0007] Preferably, the surface of the base is provided with self-locking pads, two of which are the same size, and a waterproof pad is movably attached to the surface of the base.

[0008] Preferably, a fixed block is fixedly connected to the cavity of the body, a position limiting lever is fixedly connected to one end of the limiting mechanism, and the surface of the position limiting lever is movably connected to the cavity of the fixed block.

[0009] Preferably, a reinforcing plate and an auxiliary plate are fixedly connected to the cavity of the fuselage, and one side of the reinforcing plate is fixedly connected to one side of the auxiliary plate.

[0010] Regarding the advantages of this invention, This invention utilizes the interlocking of a spline shaft and a ratchet to prevent obstruction during forward rotation of the central shaft. When the central shaft rotates in the reverse direction, the spline shaft rotates the ratchet and the body, and the screw connection between the body and the base moves the body and the movable lock. After moving the body and the movable lock to a certain distance, the screw and frictional force can restrict the rotation of the central shaft, effectively limiting the reverse rotation of the reel when the reel body rotates in the reverse direction. In addition to providing a limiting effect, it eliminates the need to drill holes in the reel body and improves the balance of the reel during use. The method of drilling holes not only easily destroys the integrity of the existing mechanism of the reel body, but also easily causes other malfunctions due to changes in the body structure during long-term use. Furthermore, problems generally occur in the internal structure of the body, significantly increasing the difficulty of repairs and solving problems such as the complexity of repairs and increased repair costs.

[0012] Hereinafter, the technical solutions in embodiments of the present invention will be clearly and completely described based on the drawings of the embodiments of the present invention. It is clear that the embodiments described are only a part of the present invention and not all embodiments. All other embodiments obtained by those skilled in the art without any creative work based on embodiments of the present invention are within the scope of the protection of the present invention.

[0013] The present invention will be described in further detail below with reference to drawings 1 to 7.

[0014] An embodiment of the present application discloses a reel check balance protection mechanism. Referring to Figures 1 and 4, the reel check balance protection mechanism includes a body 1, a base 2 screw-connected to the cavity of the body 1, a central shaft 3 rotating within the cavity of the base 2, a movable lock 4 fitted onto the surface of the central shaft 3, and a limiting mechanism 6 provided within the cavity of the body 1. The limiting mechanism 6 includes a spline shaft 601, one end of which is fixedly connected to one end of the central shaft 3, a mounting block 602 fixedly connected to the cavity of the body 1, a rotating lever 603 rotatably connected to one side of the mounting block 602, a ratchet 604 fixedly connected to the surface of the rotating lever 603, a return spring 605 fixedly connected to the cavity of the body 1, one end of which is fixedly connected to the surface of the ratchet 604, the surface of which is

[0015] The body 1 can be connected to the central shaft 3 via the base 2, and both the base 2 and one end of the central shaft 3 can be connected to the reel body. When the reel is in use, the central shaft 3 follows and rotates with it, while the base 2 and the reel body are fixed and do not rotate. The movable lock 4 connected inside the body 1 can make contact with the central shaft 3 after moving a certain distance. Furthermore, since the lumen of the movable lock 4 is set on an inclined surface, the movable lock 4 can effectively restrict the central shaft 3 through the frictional force between its internal inclined surface and the surface of the central shaft 3, and can work in cooperation with the restricting mechanism 6 to effectively restrict the reverse rotation of the central shaft 3. Furthermore, the central shaft 3 can serve to mount and fix the spline shaft 601, the ratchet 604 can be connected to the body 1 via the mounting block 602 and the rotating lever 603, the return spring 605 can return to its elastic state due to its own elasticity, and the mutual engagement between the ratchet 604 and the spline shaft 601 allows the spline shaft 601 to rotate in the forward direction and is restricted by the ratchet 604 when it rotates in the reverse direction.

[0016] Referring to Figures 1 and 2, a second screw groove 8 is provided on the surface of the base 2, a first screw groove 7 is provided on the surface of the central shaft 3, and an anti-slip layer 10 is movably bonded to the surface of the body 1. The provision of the second screw groove 8 and the first screw groove 7 allows the base 2 and central shaft 3 to be smoothly and firmly connected to the reel body, and the anti-slip layer 10 can increase the frictional force between a person's hand and the surface of the body 1, reducing hand slippage.

[0017] Referring to Figures 1 and 2, two self-locking pads 9 are provided on the surface of the base 2. The two self-locking pads 9 are the same size, and a waterproof pad 11 is movably attached to the surface of the base 2. The installation of the self-locking pads 9 reinforces the connection between the base 2 and the reel body, making it less likely for the connection between the base 2 and the reel body to loosen, while the waterproof pad 11 provides a certain level of waterproofing.

[0018] Referring to FIGS. 2 and 4, a fixed block 14 is fixedly connected to the inner cavity of the body 1, a position limiting lever 5 is fixedly connected to one end of the limiting mechanism 6, the surface of the position limiting lever 5 is movably connected to the inner cavity of the fixed block 14. By installing the fixed block 14 and the position limiting lever 5, when the body 1 moves by screwing connection with the body 2, the position limiting lever 5 can limit the movement of the body 1 through connection with the fixed block 14. When the spline shaft 601 rotates, the fixed block 14 can also play a role in limiting the rotation of the spline shaft 601 by the position limiting lever 5, making it less likely to generate rattling during rotation.

[0019] Referring to FIGS. 2 and 7, a reinforcing plate 12 and an auxiliary plate 13 are fixedly connected to the inner cavity of the body 1, one side of the reinforcing plate 12 is fixedly connected to one side of the auxiliary plate 13. The installation of the reinforcing plate 12 and the auxiliary plate 13 can play a certain reinforcing role on the body 1. When the body 1 is gripped or used, it is less likely to generate dents or the like on the surface of the body 1, and the stability of the surface of the body 1 can be enhanced.

[0020] Operating principle: When in use, people can connect the pedestal 2 and the central shaft 3 to the reel body through the first thread groove 7 and the second thread groove 8. The central shaft 3 can rotate clockwise together according to the use of the reel. When the central shaft 3 rotates, the limiting mechanism 6 can play a role in preventing reverse rotation of the central shaft 3. The anti-reverse rotation of the central shaft 3 can be divided into two methods: manual and automatic.

[0021] When it is necessary to manually reverse the central axis 3, people hold the surface of the body 1 and rotate the body 1. When the body 1 rotates in the reverse direction, the central axis 3 is rotated in a certain reverse direction by the ratchet 604. Due to the screw connection between the body 1 and the pedestal 2, the body 1 can move on the surface of the pedestal 2. When moving, the movement lock 4 is pushed to move together. After the movement lock 4 moves a certain distance, it contacts the surface of the central axis 3. Through the inclined surface installation in the inner cavity of the movement lock 4 itself and the contact between itself and the central axis 3, the frictional force between the movement lock 4 itself and the central axis 3, and the screw connection between the body 1 and the pedestal 2, the spline shaft 601 and the central axis 3 are restricted, making it difficult for the central axis 3 to rotate in the reverse direction, and further playing a role of reverse stop.

[0022] When it is necessary to automatically rotate the central axis 3, due to the forward rotation of the central axis 3, the spline shaft 601 repeatedly pushes the ratchet 604. The ratchet 604 can return due to the elasticity of the return spring 605. When the central axis 3 rotates in the reverse direction, the central axis 3 rotates the body 1 and the movement lock 4 together through the spline shaft 601 and the ratchet 604. In this case, the body 1 can reuse the screw connection with the surface of the pedestal 2 to move on the surface of the pedestal 2 while pushing the movement lock 4. After the body 1 moves a certain distance, it can no longer continue to move due to the restriction of the screw on the surface of the pedestal 2. On the other hand, the movement lock 4 also contacts the surface of the central axis 3, and the rotation of the central axis 3 is restricted by the frictional force, further realizing the position limitation to the central axis 3, making it difficult to continue rotating in the reverse direction, obtaining the effect of reverse stopping the central axis 3. At the same time, the return spring 606 can play a role of elastically returning the movement lock 4 elastically when people manually rotate the body 1 in the reverse direction and return the body 1.

[0023] The above shows and explains the basic principle, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and the descriptions in the specification are only explanations of the principle of the present invention. Without departing from the spirit and scope of the present invention, there are various changes and improvements to the present invention, and all of these changes and improvements should be understood to be within the scope of the present invention that requires protection.
