Description

Technical Field

[0001] This utility model belongs to the technical field of fishing tackle, and in particular relates to a hollow safety rope. Background Technology

[0002] When fishing, if the angler is distracted or leaves the area, the fishing rod may fall into the water due to the fish's pull, resulting in loss. To address this problem, a safety line is typically installed at the end of the fishing rod and secured to an external support, such as the angler's hand or a support rod. Chinese patent CN222515964U discloses a "Multi-section Carbon Fiber Fishing Rod," which incorporates a safety line mechanism at the end of the handle section. This mechanism includes a housing, a reel, a top plate, a damping layer, a rope, a locking mechanism, and a lever. The housing and handle section are interlocked, solving the problem of lost and misplaced safety lines. However, this design requires a slot in the handle section, and the interlocking structure of the housing and handle section is relatively simple. Different adaptation structures are needed for different rod sizes, resulting in low flexibility and inconvenience. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a hollow safety rope that can be fixedly assembled on different external supports, and is highly flexible in use.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a hollow safety rope, comprising:

[0005] The outer shell is hollow inside and has axially formed channels for external supports to pass through;

[0006] The locking mechanism includes at least a movable component that extends partially out of the housing, a clamping spring located in the channel and linked to the movable component, and a base that engages with the housing to prevent rotation. When an external force is applied to the movable component, the clamping spring can clamp or release an external support in the channel.

[0007] A rope winding mechanism includes at least a rope with one end extending out of the outer shell, a wheel seat for winding the rope, and an elastic reel. The two ends of the elastic reel are respectively connected to the wheel seat and the outer shell, and are used to drive the wheel seat to rotate relative to the outer shell to achieve winding or unwinding of the rope.

[0008] The hollow safety rope of this invention forms a channel in the middle of the outer shell for external supports to pass through. The locking mechanism securely clamps the external support within the channel. Due to the movable setting of the clamping spring, external supports of different outer diameters and sizes can be securely clamped within the channel. It has a wide range of applications, can adapt to different usage environments, and provides a good user experience.

[0009] Furthermore, the movable component includes a driving member that partially extends out of the outer shell, a movable member sleeved on the driving member, and an actuating member connected to the movable member. The clamping spring is movably connected to the base and engages with the inclined surface of the actuating member. When an external force is applied to the driving member, the movable member translates axially relative to the driving member, and the actuating member drives the clamping spring closer to the center of the channel. The movable component has a reasonable structural design. The partial extension of the driving member out of the outer shell facilitates the application of external force to rotate the driving member. The engagement of the clamping spring with the inclined surface of the actuating member ensures that the clamping spring can gradually translate to clamp the external support, resulting in more stable and effective clamping of the external support.

[0010] Furthermore, the outer wall of the drive component forms an external threaded section, and the movable component engages with the base to prevent rotation. When an external force is applied to rotate the drive component, the movable component translates axially within the external threaded section of the drive component. The design of the external threaded section not only enables the translation of the movable component but also ensures that the movable component does not move in the opposite direction relative to the drive component when the applied external force is stopped, resulting in a more stable structure.

[0011] Furthermore, the base is provided with a radially extending limiting slot, to which the clamping spring is movably connected. The structural design of the movable connection between the base and the clamping spring is reasonable, ensuring that the clamping spring has a large radial range of motion.

[0012] Furthermore, the clamping spring is provided with a protrusion, which is anti-disengaged and connected to the actuating member. Both the protrusion and the actuating member have inclined surfaces on their mating sides. The inclined surfaces of the protrusion and the actuating member allow the moving member to drive the clamping spring in a stepped manner without abrupt changes, ensuring that the clamping spring gradually and securely clamps the external support.

[0013] Furthermore, the movable component includes a movable ring sleeved on the drive component and a connecting rod connected to the movable ring and extending axially. The actuating component is connected to the end of the connecting rod, and the base forms a slot for the connecting rod to be engaged.

[0014] Furthermore, a first sleeve is formed inside the outer shell, and the wheel seat has a second sleeve located radially outside the first sleeve. The elastic reel is wound between the first and second sleeves and connected to both sleeves. The rope is wound around the second sleeve. The elastic reel, positioned between the first and second sleeves, is not interfered with by other components, allowing for smoother winding and unwinding, and effectively driving the second sleeve to rotate circumferentially relative to the first sleeve.

[0015] Furthermore, the system also includes a wiring mechanism, comprising a gear meshing with a wheel seat, a column connected to the gear and having a helical drive groove, a wire hole for the rope to pass through, a protrusion connected to the wire hole, and a wiring rod extending along the length of the second sleeve. The wire hole is movably connected to the wiring rod, and the protrusion extends into the helical drive groove. When the wheel seat drives the gear to rotate, the helical drive groove drives the wire hole to move through the protrusion. This wiring mechanism allows the rope to wind sequentially along the length of the second sleeve, preventing all the rope from winding in the same place on the outer wall of the second sleeve, resulting in a more efficient wiring arrangement.

[0016] Furthermore, a positioning protrusion and a positioning groove are formed between the first sleeve and the base, and the positioning protrusion is engaged in the positioning groove to achieve an anti-rotation fit between the outer shell and the base.

[0017] Furthermore, the number of clamping springs is at least two, and they are arranged radially symmetrically. This arrangement makes the clamping springs hold the external support more evenly and stably, avoiding uneven force on the external support and causing displacement.

[0018] The beneficial effects of this utility model are: external supports of different outer diameters and sizes can pass through the channel and be securely clamped by the locking mechanism, which is convenient for fixing and assembling the safety rope in different positions, adapting to different usage scenarios and providing a better user experience; the overall structural design is reasonable, and the clamping of external supports is more stable and effective; the wiring mechanism allows the rope to be wound sequentially along the length of the second sleeve, avoiding all the ropes from being wound in the same place on the outer wall of the second sleeve, making the wiring more reasonable.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0033] like Figure 1 , Figure 2As shown, a hollow safety rope includes an inner hollow shell 1, a locking mechanism 2, and a rope winding mechanism 6. The shell 1 has a channel 11 formed in the axial direction for an external support to pass through, which can be a support rod or other structure.

[0034] The locking mechanism 2 includes at least a movable component 3 that extends partially out of the outer shell 1, a clamping spring 4 located in the channel 11 and linked with the movable component 3, and a base 5 that is anti-rotationally engaged with the outer shell 1. When an external force is applied to the movable component 3, the clamping spring 4 can clamp or release the external support in the channel 11.

[0035] Specifically, such as Figures 3-7 As shown, the movable component 3 includes a driving member 31 that partially extends out of the outer shell 1, a movable member 32 sleeved on the driving member 31, and an actuating member 33 connected to the movable member 32. The driving member 31 is generally hollow cylindrical, thus forming an effective channel 11 with the outer shell 1. Its outer wall forms an externally threaded section 311, and the unthreaded portion of the driving member 31 extends from the end face of the outer shell 1. The movable member 32 includes a movable ring 321 sleeved on the driving member 31, and a connecting rod 322 connected to the movable ring 321 and extending axially. In this embodiment, the movable ring 321 is a hollow annulus sleeved on the externally threaded section 311. There are two connecting rods 322, which are radially symmetrically arranged on both sides of the movable ring 321. The actuating members 33 are connected to the end of the connecting rod 322 away from the movable ring 321, and there are also two of them. Of course, in other embodiments, the number of connecting rods 322 can also be three, four, etc., which are evenly spaced along the circumference of the movable ring 321, and the number of actuating members 33 corresponds to the number of connecting rods 322.

[0036] The movable part 32 is anti-rotationally engaged with the base 5, so that when an external force is applied to rotate the driving part 31, the movable part 32 cannot rotate. Under the action of the external thread section 311 of the driving part 31, the movable part 32 can only translate axially along the external thread section 311. In order to achieve the anti-rotational engagement between the movable part 32 and the base 5, a groove 52 is formed on the outer wall of the base 5 for the connecting rod 322 to be engaged.

[0037] In this embodiment, the base 5 includes a first hollow ring 541 and a second hollow ring 542 at both ends, and a connecting rod 543 connecting the first hollow ring 541 and the second hollow ring 542. The base 5 is structured in this way to form an effective channel 11 within the outer shell 1. The clamping spring 4 is movably connected to the base 5. Specifically, a limiting slot 51 is provided on the opposite side of the first hollow ring 541 and the second hollow ring 542. The limiting slot 51 extends radially, and the two ends of the clamping spring 4 form insertion posts 42. The insertion posts 42 can be movably inserted into the limiting slot 51, thereby clamping the spring 4 to move radially in the hollow area excluding the connecting rod 543. Here, radial refers to the radial direction of the second hollow ring 542 of the base 5. Of course, the first hollow ring 541 and the second hollow ring 542 are concentric and coaxial, and their radial directions are the same. The number of clamping spring pieces 4 is the same as the number of connecting rods 322, which is at least two. They are arranged symmetrically in the radial direction, or they can be evenly spaced in the circumferential direction, so that the clamping of the external support is more balanced and stable, and the external support is prevented from shifting due to uneven force.

[0038] The outer wall of the clamping spring 4 is provided with a protrusion 41, which is connected to the actuating member 33 in an anti-disengagement fit. Specifically, a T-shaped anti-disengagement block 331 and an anti-disengagement groove 411 are formed on the side where the protrusion 41 and the actuating member 33 are in contact. The anti-disengagement block 331 is inserted into the anti-disengagement groove 411, so that the two will not separate radially. Moreover, the side where the protrusion 41 and the actuating member 33 are in contact are both formed with inclined surfaces, and the two inclined surfaces have the same inclination direction and the same inclination angle.

[0039] When an external force is applied to rotate the drive component 31, the movable ring 321 translates along the external thread section 311 towards the direction close to the second hollow ring 542. At this time, under the action of the inclined surface on the side where the protrusion 41 and the actuating component 33 are in contact, such as Figure 6 , Figure 7 As shown, the actuator 33 drives the protrusion 41 closer to the center of the channel 11, which in turn drives the clamping spring 4 connected to the protrusion 41 closer to the center of the channel 11, thus clamping the external support inside the channel 11. When it is necessary to remove the external support from the channel 11, the actuator 311 is rotated in the opposite direction, causing the movable ring 321 to translate along the external thread section 311 in a direction away from the second hollow ring 542, which in turn drives the clamping spring 4 away from the center of the channel 11, releasing the clamping effect on the external support.

[0040] When in use, the external support is inserted into the channel 11. By applying external force to the drive member 31 protruding from the outer shell 1, it is rotated, driving the clamping spring 4 to firmly clamp the outer wall of the external support, thus achieving the fixed assembly of the hollow safety rope. Since the movable member 32 is threadedly connected to the external thread section 311, the clamping spring 4 will not automatically move away from the external support without the action of external force.

[0041] like Figure 8 , Figures 10-12 As shown, the rope winding mechanism 6 includes at least a rope 61 with one end extending out of the outer casing 1, a wheel seat 62 for winding the rope 61, and an elastic reel 63. The two ends of the elastic reel 63 are connected to the wheel seat 62 and the outer casing 1 respectively, and are used to drive the wheel seat 62 to rotate relative to the outer casing 1, thereby realizing the winding or unwinding of the rope 61. Figure 9 As shown, a first sleeve 12 is formed inside the outer casing 1, and the wheel seat 62 has a second sleeve 621 located radially outside the first sleeve 12. The rope 61 is wound around the outer wall of the second sleeve 621, and the elastic spool 63 is wound between the first sleeve 12 and the second sleeve 621 and is connected to the first sleeve 12 and the second sleeve 621 respectively.

[0042] A positioning protrusion 121 and a positioning groove 53 are formed between the first sleeve 12 and the base 5. Specifically, in this embodiment, as shown... Figure 9 As shown, a positioning protrusion 121 is formed on the inner wall of the first sleeve 12, as... Figure 3 As shown, positioning grooves 53 are formed in both the first hollow ring 541 and the second hollow ring 542 of the base 5, and positioning protrusions 121 are engaged in the positioning grooves 53, thereby achieving an anti-rotation fit between the outer shell 1 and the base 5. Of course, the positions of the positioning grooves and positioning protrusions can also be interchanged, and there is no specific limitation.

[0043] When the rope 61 is pulled outward, the wheel seat 62 will also rotate relative to the outer shell 1. At this time, the elastic reel 63 is also pulled and extended synchronously. Once the external force of pulling the rope 61 outward is stopped, the rope 61 will be wound around the outer wall of the second sleeve 621 again under the automatic winding and resetting action of the elastic reel 63.

[0044] To prevent all the ropes 61 from getting wrapped around the same spot on the outer wall of the second sleeve 621, a wiring mechanism 7 is provided, which includes a gear 71 that meshes with the wheel seat 62, a column 72 connected to the gear 71 and having a helical drive groove 73, a wire hole 74 through which the ropes 61 pass, a protrusion 75 connected to the wire hole 74, and a wiring rod 76 extending along the length of the second sleeve 621. Specifically, the wiring rod 76 extends along a direction parallel to the axis of the second sleeve 621. Specifically, meshing teeth 622 are formed on the outer ring of the wheel seat 62. The gear 71 is set inside the outer shell 1, and its outer diameter is much smaller than the outer diameter of the outer ring of the wheel seat 62. The column 72 is vertically connected to the center of the gear 71. The helical drive groove 73 is a groove opened on the outer wall of the column 72. It is spirally arranged on the outer wall of the column 72 like a thread structure. In order to accommodate the gear 71 to rotate the column 72 clockwise or counterclockwise, the helical drive groove 73 can include a groove structure that extends helically in two directions, that is, the two helical grooves intersect and communicate with each other.

[0045] The wire hole 74 is movably connected to the wiring rod 76. Specifically, a mounting block 741 is connected to the outer wall of the wire hole 74, and the wiring rod 76 is inserted into the mounting block 741. A protrusion 75 is connected in the direction perpendicular to the wiring rod 76, and the other end of the protrusion 75 extends into the spiral drive groove 73. When the rope 61 on the second sleeve 621 drives the wheel seat 62 to rotate, the wheel seat 62 drives the gear 71 to rotate through the meshing of the meshing teeth 622 and the gear 71. The spiral drive groove 73 drives the protrusion 75 to move, which in turn drives the wire hole 74 to move along the wiring rod 76. Thus, the rope 61 in the wire hole 74 can be wound sequentially along the length of the second sleeve 621, instead of being concentrated in one area, making the wiring more efficient.

[0046] like Figure 12 As shown, one end of the rope 61 is fixedly connected to the reel seat 62, and the other end of the rope 1 passes through the line hole 74 and is connected to the fishing rod. When the fishing rod falls from the external support, the rope 1 is pulled, and the rope 1 wrapped around the second sleeve 621 unfolds outward, making it easy to quickly retrieve the fishing rod.

[0047] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
