Description

Technical Field

[0001] This application relates to the field of marine machinery and equipment technology, specifically to an anchor lock frame. Background Technology

[0002] Anchor locks are primarily used to secure and control a vessel's position on the water. When fishing in still water or mooring, anchor locks can help keep the vessel in a specific position and prevent it from drifting.

[0003] An anchor lock consists of an anchor and a rope. The crew can lower the anchor into the water and secure it to the bottom. The crew can then adjust the length and position of the anchor by simply locking and unlocking it to keep the vessel in place according to changes in water flow and wind direction.

[0004] Existing anchors are bulky and take up a lot of space when not in use, making them inconvenient to store and protect. Furthermore, when in use, users find it difficult to pull the rope, as the force is uneven and requires a lot of effort.

[0005] Therefore, the structure of the existing anchor lock frame has room for further improvement. Utility Model Content

[0006] In view of this, and in response to the technical problems of existing ship anchors being large in size, occupying a lot of space, and being inconvenient to store and protect when not in use, this application provides a ship anchor lock frame. By changing the structure of the ship anchor lock frame, the space occupied by the ship anchor when not in use is reduced, making it convenient to store and place, and improving the user's efficiency and comfort.

[0007] To achieve the above objectives, this application provides the following technical solution: an anchor lock frame, comprising:

[0008] The pull rope connected to the anchor;

[0009] The housing has the pull rope located on it, and the housing is provided with a locking component for locking or unlocking the pull rope. The locking component is used to clamp the pull rope to lock the anchor.

[0010] The shell has an inner cavity that accommodates at least part of the anchor; when the rope is taut, the rope is in a basically horizontal state inside the shell.

[0011] Compared to existing technologies, this invention includes a locking component and a housing. The locking component clamps the pull rope to lock the anchor, allowing the user to keep the vessel in a specific position and prevent drifting when fishing in still water or mooring. The anchor lock holder in this application has an internal cavity in the housing to accommodate at least part of the anchor, resulting in a smaller space occupied by the anchor when not in use, facilitating storage and placement, thereby improving user efficiency and comfort. When the pull rope is taut, it remains essentially horizontal within the housing under force, forming a straight line. This reduces the force required for the user to pull the rope, allowing for easy and smooth pulling, thus improving the user experience.

[0012] Preferably, the end of the housing away from the locking assembly has an opening, and when the anchor is in the retracted state, the anchor at least partially passes through the opening and is located in the inner cavity of the housing.

[0013] In this embodiment, by providing an opening, the anchor can be partially inserted into the inner cavity of the shell when it is retracted, which can effectively store the anchor, prevent it from being exposed, and reduce the space occupied by the anchor.

[0014] Preferably, it also includes a roller and a guide wheel, the two ends of which are connected to the side wall of the housing, the roller and the guide wheel are disposed inside the housing, the roller is located between the locking assembly and the guide wheel, and the anchor can be at least partially located on the guide wheel.

[0015] In this embodiment, by setting rollers and guide wheels, the user can pull the rope more smoothly, reducing frictional resistance and wear. The rope can also move along a designated path, effectively dispersing the stress points of the rope, avoiding local stress concentration, reducing the risk of rope breakage, and improving operating efficiency and service life.

[0016] Preferably, the housing is further provided with a fixing rod, which is installed on the vessel and located between the roller and the vessel.

[0017] In this embodiment, the fixing rod is used to fix the shell and also serves to support the shell, so that the shell can be stably installed on the boat, making it convenient for users to fix the boat. At the same time, the fixing rod can be plugged into a common socket on the boat, without the need for a specific socket, making it widely applicable and increasing the flexibility of use.

[0018] Preferably, the housing includes a bottom plate and two parallel side plates, with both ends of the bottom plate connected to the two side plates respectively, and the side of the bottom plate away from the side plates connected to a fixing rod;

[0019] The side plate has a first bend, which is located between the guide wheel and the roller. The first bend is recessed in the direction away from the fixed rod and has an obtuse angle.

[0020] In this embodiment, the bending design not only increases the strength of the housing, but also allows the side plate to undergo a certain degree of elastic deformation when subjected to pressure, thereby absorbing part of the impact force and further improving the durability of the locking device.

[0021] Preferably, the side plate is further provided with a second bend, which is located at one end of the side plate near the opening. The second bend protrudes toward the top of the side plate away from the top and has an arc-shaped structure.

[0022] Viewed vertically, the lowest point of the side panel near the locking assembly is higher than the lowest point of the side panel near the opening.

[0023] In this embodiment, by setting a height difference, when the anchor enters the water and is pulled up, the rope can be pulled more easily when it retracts, making the process of pulling the rope smoother and more convenient, thus reducing the force required for the user to pull.

[0024] Preferably, the locking assembly includes a rotating shaft and a locking block. The two ends of the rotating shaft are respectively connected to the side wall of the housing, and the locking block is sleeved on the rotating shaft, and the locking block can rotate relative to the rotating shaft.

[0025] A bushing is provided between the rotating shaft and the locking block. The bushing is fitted onto the rotating shaft, and the inner diameter of the bushing is adapted to the outer diameter of the rotating shaft.

[0026] In this embodiment, the pivot acts as the hub of the locking block, allowing the locking block to rotate flexibly around the pivot, effectively clamping and releasing the pull rope. This effectively prevents the pull rope from slipping out accidentally, and when the user needs to adjust the length of the pull rope, the pivot drives the locking block to move the pull rope smoothly, reducing operating resistance.

[0027] Preferably, the locking block includes a connecting part and a rotating part, the connecting part is fixedly connected to the rotating part, the rotating part is sleeved on the rotating shaft, and the connecting part is located on the side of the rotating part facing the roller;

[0028] Viewed vertically, the lowest point of the connecting part is higher than the lowest point of the rotating part.

[0029] In this embodiment, by setting the lowest point of the connecting part to be higher than the lowest point of the rotating part, it is ensured that the connecting part will not interfere with the bottom plate of the housing during the movement, avoiding jamming, improving the smoothness of the movement of the locking block, facilitating the smooth pulling of the rope, and ensuring the rotational freedom of the locking block.

[0030] Preferably, the connecting part is provided with a channel for the pull rope to pass through, the diameter of the channel gradually increases from the top to the bottom, and the channel is connected to the rotating part by an arc surface transition;

[0031] The channel has a trumpet-shaped structure, and the end of the rotating part away from the axis of rotation is gear-shaped.

[0032] In this embodiment, the funnel-shaped structure allows the pull rope to pass through the channel more smoothly, reducing friction and jamming between the pull rope and the edge of the channel, and improving the smoothness of pulling the pull rope.

[0033] Preferably, the housing is further provided with a mating block, which engages with the rotating part to clamp the pull rope;

[0034] The mating block has a gear shape on the side facing the rotating part.

[0035] In this embodiment, the gear shape of the mating block meshes with the gear shape of the rotating part, ensuring a tight and precise fit between the two. When the rotating part rotates, the mating block can move synchronously or apply clamping force to achieve stable clamping of the pull rope and prevent the pull rope from slipping or loosening.

[0049] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0050] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0051] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0052] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 9 illustrate.

[0053] This embodiment provides an anchor lock frame, which is applied in the field of marine machinery equipment technology, specifically, as follows: Figures 1 to 9As shown, the device includes a pull rope 2 connected to the anchor 1 and a housing 3. The pull rope 2 is located on the housing 3, and the housing 3 is provided with a locking component 4 for locking or unlocking the pull rope 2. The locking component 4 is used to clamp the pull rope 2 to lock the anchor 1. The housing 3 is provided with an inner cavity that accommodates at least part of the anchor 1. When the pull rope 2 is taut, the pull rope 2 is in a basically horizontal state inside the housing 3, presenting a straight line. This reduces the force required for the user to pull the pull rope 2, making it convenient and smooth for the user to pull the pull rope 2, thereby improving the user experience.

[0054] When a user is fishing in still water or mooring, anchor 1 is placed in the water. The weight and shape of anchor 1 will fix it to the bottom. Then, locking component 4 is used to lock the pull rope 2, thus fixing the boat in the user's desired position. When the user needs to move the boat, locking component 4 is used to unlock pull rope 2, and then pulling pull rope 2 will pull anchor 1 out of the water, allowing the user to start the boat and move away.

[0055] Among them, such as Figures 5 to 6 As shown, the anchor 1 includes an anchor head 11 and an anchor rod 12. One end of the anchor rod 12 is fixedly connected to the rope 2, and the other end of the anchor rod 12 is fixedly connected to the anchor head 11. The anchor head 11 has a semi-circular arc structure. The end of the housing 3 away from the locking component 4 is provided with an opening 31. When the anchor 1 is in the retracted state, the anchor 1 passes through the opening 31 at least partially and is located in the inner cavity of the housing 3, that is, the anchor rod 12 is located inside the housing 3, which can effectively store the anchor rod 12, so that the anchor 1 occupies less space when it is not in operation.

[0056] The diameter of the anchor head 11 is larger than the diameter of the opening 31, and the diameter of the opening 31 is larger than the diameter of the anchor rod 12. When the anchor 1 needs to be retracted, that is, the anchor rod 12 passes through the opening 31 and is located in the inner cavity of the housing 3, and the anchor head 11 is close to the housing 3. This makes the overall structure of the anchor 1 locking frame compact, so that the anchor 1 occupies less space when not in operation, making it convenient to store and place, and improving the user's efficiency and comfort. When the locking component 4 is rotated to the unlocked position, the pull rope 2 is in the unlocked state. Under the action of force, the pull rope 2 is in a straight line, reducing the force required for the user to pull the pull rope 2, making it convenient and smooth for the user to pull the pull rope 2, thereby improving the user experience.

[0057] It should be noted that the anchor rod 12 can also be detachably connected to the rope 2, making it convenient to disassemble and replace the rope 2 or the anchor rod 12.

[0058] Furthermore, such as Figure 2As shown, it also includes roller 5 and guide wheel 6. The two ends of roller 5 and guide wheel 6 are connected to the side wall of housing 3, respectively. Roller 5 and guide wheel 6 are disposed inside housing 3. Roller 5 is located between locking assembly 4 and guide wheel 6. Anchor 1 is at least partially located on guide wheel 6. By setting roller 5 and guide wheel 6, the user can pull the rope 2 more smoothly, reducing frictional resistance and wear. It also allows the rope 2 to move along a designated path, effectively distributing the stress points of the rope 2, avoiding local stress concentration, reducing the risk of rope 2 breakage, and improving operating efficiency and service life. Multiple mounting holes are provided on the side wall of housing 3. The two ends of roller 5 and guide wheel 6 are threadedly connected to the side wall of housing 3 through the mounting holes. The threaded connection facilitates the disassembly and replacement of roller 5 and guide wheel 6.

[0059] Furthermore, such as Figure 9 As shown, the housing 3 is also provided with a fixing rod 32. The fixing rod 32 is installed on the boat. The end of the fixing rod 32 away from the housing 3 is detachably connected to the boat through the base 7. The fixing rod 32 and the base 7 are detachably connected, which makes it easy to replace and disassemble the base 7. The fixing rod 32 is located between the roller 5 and the boat, and the fixing rod 32 is located below the roller 5. The fixing rod 32 is used to fix the housing 3 and also serves to support the housing 3, so that the housing 3 can be stably installed on the boat, making it convenient for users to fix the boat. At the same time, the fixing rod 32 can be plugged into a common socket on the boat, without the need for a specific socket, which makes it widely applicable and increases the flexibility of use.

[0060] Furthermore, such as Figures 5 to 8 As shown, the housing 3 includes a base plate 33 and two parallel side plates 34. The two ends of the base plate 33 are fixedly connected to the two side plates 34 respectively. The side of the base plate 33 away from the side plates 34 is fixedly connected to the fixing rod 32. The side plate 34 is provided with a first bend 341, which is located between the guide wheel 6 and the roller 5. The first bend 341 is concave in the direction away from the fixing rod 32 and is located in the middle of the side plate 34. The first bend 341 is an obtuse angle. The bend design not only increases the strength of the housing 3, but also allows the side plate 34 to have a certain elastic deformation when subjected to pressure, thereby absorbing part of the impact force and further improving the durability of the locking device.

[0061] It should be noted that the base plate 33 can be detachably connected to the fixing rod 32, making it convenient to replace and install the fixing rod 32.

[0062] Furthermore, such as Figure 1As shown, the side plate 34 is also provided with a second bend 342. The second bend 342 is located at the end of the side plate 34 near the opening 31. The second bend 342 protrudes in the direction away from the top of the side plate 34. The second bend 342 is an arc-shaped structure. From the vertical direction, that is, the second bend 342 protrudes downward. The lowest point of the end of the side plate 34 near the locking component 4 is higher than the lowest point of the end of the side plate 34 near the opening 31. That is, the end of the side plate 34 near the opening 31 is inclined. By setting the height difference, when the anchor 1 enters the water and the anchor 1 is pulled up, the pull rope 2 can be retracted more easily. The process of pulling the pull rope 2 is smoother and more convenient, that is, the force required for the user to pull is reduced.

[0063] The guide wheel 6 is positioned above the center of the second bend 342 and is located on the side of the opening 31 near the base plate 33. The base plate 33 is used to limit the guide wheel 6 so that when the guide wheel 6 is misaligned, the base plate 33 can prevent the guide wheel 6 from popping out toward the locking component 4, thus avoiding injury to the user and improving safety.

[0064] Furthermore, such as Figures 2 to 4 As shown, the locking assembly 4 includes a rotating shaft 41 and a locking block 42. The two ends of the rotating shaft 41 are connected to the side wall of the housing 3, and the locking block 42 is sleeved on the rotating shaft 41. The locking block 42 can rotate relative to the rotating shaft 41. A bushing 43 is provided between the rotating shaft 41 and the locking block 42. The bushing 43 is sleeved on the rotating shaft 41, and the inner diameter of the bushing 43 is adapted to the outer diameter of the rotating shaft 41. By setting the rotating shaft 41, the movement of the locking block 42 can be facilitated, thereby making the operation of the user pulling the pull rope 2 more convenient and safer. The rotating shaft 41 serves as the pivot of the locking block 42, allowing the locking block 42 to rotate flexibly around the rotating shaft 41, realizing effective clamping and release of the pull rope 2. This effectively prevents the pull rope 2 from slipping off accidentally. When the user needs to adjust the length of the pull rope 2, the rotating shaft 41 drives the locking block 42 to make the pull rope 2 move smoothly, reducing operating resistance.

[0065] Furthermore, such as Figures 3 to 4As shown, the locking block 42 includes a connecting part 421 and a rotating part 422. The connecting part 421 and the rotating part 422 are fixedly connected. The rotating part 422 is sleeved on the rotating shaft 41. The connecting part 421 is located on the side of the rotating part 422 facing the roller 5. The rotating part 422 can rotate relative to the connecting part 421. The connecting part 421 and the rotating part 422 are connected by an arc transition. The arc transition can reduce the local stress concentration of the connecting part 421 and the rotating part 422. From the vertical direction, the lowest point of the connecting part 421 is higher than the lowest point of the rotating part 422. The end of the rotating part 422 near the bottom plate 33 cooperates with the bottom plate 33, so that the pull rope 2 can be clamped, thereby realizing the locking of the anchor 1. By setting the height difference, it is ensured that the connecting part 421 will not interfere with the bottom plate 33 of the shell 3 during the movement, avoiding jamming, improving the smoothness of the movement of the locking block 42, facilitating the smooth pulling of the pull rope 2, and ensuring the rotational freedom of the locking block 42.

[0066] Among them, such as Figures 3 to 4 As shown, the connecting part 421 is provided with a channel 4211 for the pull rope 2 to pass through. The diameter of the channel 4211 gradually increases from the top to the bottom. The channel 4211 and the rotating part 422 are connected by an arc transition. The channel 4211 has a trumpet-shaped structure with rounded edges. The trumpet-shaped structure makes it easier for the pull rope 2 to pass through the channel 4211, reducing friction and jamming between the pull rope 2 and the edge of the channel 4211, and improving the smoothness of pulling the pull rope 2. The end of the rotating part 422 away from the rotating shaft 41 is gear-shaped, which can improve the effect of clamping the pull rope 2, increase the friction between the pull rope 2 and the rotating part 422, and make the pull rope 2 less likely to loosen or slip.

[0067] Among them, such as Figure 6 As shown, the housing 3 is also provided with a mating block 35, which is connected to the base plate 33. The mating block 35 is located between the base plate 33 and the locking assembly 4. The mating block 35 cooperates with the rotating part 422 to clamp the pull rope 2. The side of the mating block 35 facing the rotating part 422 is gear-shaped. The gear shape of the mating block 35 meshes with the gear shape of the rotating part 422 to ensure that the two are tightly and precisely matched. When the rotating part 422 rotates, the mating block 35 cooperates with the rotating part 422 to achieve stable clamping of the pull rope 2 and prevent the pull rope 2 from slipping or loosening.

[0068] Furthermore, such as Figures 5 to 6As shown, the housing 3 is also equipped with a fixing component 36. Both ends of the fixing component 36 are connected to two side plates 34 respectively. The fixing component 36 is located between the two side plates 34. The fixing component 36 includes a protective plate 361 and two parallel support plates 362. The side of the protective plate 361 facing the locking component 4 is connected to the ends of the two support plates 362. The guide wheel 6 is located between the two support plates 362. The two support plates 362 are used to limit the guide wheel 6, ensuring that the guide wheel 6 maintains a stable axial position during operation, preventing the guide wheel 6 from shifting or falling off due to uneven force or vibration, thereby ensuring the normal operation of the entire locking component 4. At the same time, the protective plate 361 also plays a certain safety protection role, preventing operators from accidentally touching the guide wheel 6 and improving safety. The protective plate 361 has a through hole for the pull rope 2 to pass through, allowing the pull rope 2 to move along a set trajectory, thereby improving the smoothness of pulling the pull rope 2.

[0069] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
