Description

Technical Field

[0001] This utility model relates to the field of fishing gear technology, and in particular to a float adjustment device. Background Technology

[0002] Fish activity patterns and feeding habits vary significantly due to environmental factors such as weather changes, water temperature fluctuations, and air pressure variations. During fishing, anglers often need to flexibly adjust the float's position in the water to control the hook's depth. However, traditional fishing methods rely on anglers repeatedly casting and retrieving the float manually, which is not only time-consuming and laborious but can also disturb the fish, affecting fishing efficiency and the overall experience. Utility Model Content

[0003] To address the problem in existing technologies where the float needs to be pulled out of the water to be manually adjusted, this invention provides a float adjustment device that allows for easy adjustment of the float in water.

[0004] To achieve the above objectives, the following technical solution is provided:

[0005] A float adjustment device, characterized in that it comprises:

[0006] The casing has an axially penetrating inner cavity, and the upper section of the inner cavity has inclined structures on both sides that reduce the radial downward contraction of the inner cavity opening.

[0007] The wire clamping rod is slidably installed inside the housing, and elastic clamping pieces that cooperate with the inclined structure are provided on both sides of the upper end of the wire clamping rod.

[0008] The lever mechanism includes a lever rotatably mounted on the outside of the housing and a rotating pressure block inside the housing, with the lever connected to the rotating pressure block.

[0009] The connecting block can slide along the axial direction of the casing and connect to the bottom of the clamping rod. Both the clamping rod and the connecting block are provided with through holes in the axial direction for the fishing line to pass through.

[0010] The telescopic locking mechanism is located on the upper part of the connecting block and is used to cooperate with the lever and the rotating pressure block. When the rotating pressure block flips or resets, the telescopic locking mechanism drives the connecting block and the clamping rod to move intermittently downward or upward and can fix the sliding position of the connecting block.

[0011] Furthermore, the telescopic locking mechanism includes a sliding pawl sleeve below the rotating pressure block, a locking member that cooperates with the sliding pawl sleeve, and an elastic member located at the bottom of the locking member. The sliding pawl sleeve and the locking member are axially provided with through holes for the wire clamping rod to pass through. An axial sliding structure is provided between the sliding pawl sleeve and the housing. The rotation of the lever drives the rotating pressure block to make the sliding pawl sleeve slide up and down, causing the locking member to rotate intermittently. The bottom of the locking member is provided with first magnetic members arranged at intervals, and the magnetic poles of adjacent first magnetic members are opposite. The connecting block is provided with a second magnetic member at one end near the bottom of the locking member, which is opposite in position to the first magnetic member and has the opposite magnetic pole.

[0012] Furthermore, the axial sliding structure includes a radially arranged groove on the sliding pawl sleeve and a radially arranged guide rail on the inner wall of the sleeve. The bottom of the sliding pawl sleeve is provided with a first helical tooth in the circumferential direction, the upper part of the locking member is provided with a second helical tooth in the circumferential direction that cooperates with the bottom of the sliding pawl sleeve, and the bottom of the guide rail is provided with a third helical tooth that cooperates with the second helical tooth.

[0013] Furthermore, there are two rotating pressure blocks, and the lever includes a first support rod and a second support rod arranged symmetrically. The upper ends of the first support rod and the second support rod are connected, and the bottom ends are respectively connected to the two rotating pressure blocks inside the casing.

[0014] Furthermore, the top side of the sliding pawl sleeve is provided with a mounting platform, and the rotating pressure block is located on the mounting platform. The bottom of the rotating pressure block is a plane that fits with the mounting platform, or the rotating pressure block is an eccentric cam.

[0015] Furthermore, the top side of the sliding pawl sleeve is provided with a mounting platform, and the rotating pressure block is located on the mounting platform. The bottom of the rotating pressure block is a plane that fits with the mounting platform, or the rotating pressure block is an eccentric cam.

[0016] Furthermore, a first plug and a second plug with through holes are respectively provided at both ends of the casing, and an elastic element is disposed between the second plug and the connecting block.

[0017] Furthermore, a rotating cavity matching the rotating pressure block is provided inside the casing.

[0018] The beneficial effects of this utility model are as follows: By pulling the fishing line, the clamping rod in this device moves axially downward within the casing, thereby controlling the elastic clip to clamp the fishing line, fixing the distance between the hook and the device, and entering the fishing state. Alternatively, the clamping rod can be moved axially upward within the casing, causing the elastic clip to release the fishing line and adjust the hook's entry height into the water. Compared with the prior art, anglers do not need to frequently pull the hook out to the horizontal and then adjust the distance between the float and the hook to adjust the hook's entry height into the water, avoiding frequent hook entry into the water and disturbing the fish. The operation is also convenient. Attached Figure Description

Detailed Implementation

[0033] The following detailed description of a float adjustment device according to the present invention is provided in conjunction with specific embodiments.

[0034] It should be noted that the depth at which the hook enters the water is related to the fishing conditions. Fish conditions are often affected by factors such as weather, air pressure, water depth, water temperature, and the water level at which fish inhabit. Anglers can judge the water depth by the balance between the float and the sinker. For example, if the number of segments of the float above the water decreases rapidly after the float stands upright in the water, it indicates that the water is deeper. If the number of segments on the float suddenly sinks or the number of segments above the water decreases, it may be that a fish has taken the bait, or the water depth in front of the fishing spot has increased. If the number of segments on the float increases, it may be that the water in front of the fishing spot is shallow or the hook has touched the bottom.

[0035] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, a float adjustment device includes:

[0036] The casing 1 has an axially penetrating inner cavity, and the upper section of the inner cavity has inclined structures 2 on both sides that reduce the radial downward contraction of the inner cavity opening.

[0037] The clamping rod 3 is slidably set inside the housing 1, and elastic clamping pieces 4 that cooperate with the inclined structure 2 are provided on both sides of the upper end of the clamping rod 3.

[0038] The lever mechanism includes a lever 5 rotatably disposed on the outside of the housing 1 and a rotating pressure block 6 inside the housing 1, with the lever 5 connected to the rotating pressure block 6.

[0039] The connecting block 7 can slide along the axial direction of the sleeve 1 and connect to the bottom of the clamping rod 3. Both the clamping rod 3 and the connecting block 7 are provided with through holes in the axial direction for the fishing line 24 to pass through.

[0040] The telescopic locking mechanism is located on the upper part of the connecting block 7 and is used to cooperate with the lever 5 and the rotating pressure block 6. When the rotating pressure block 6 flips or resets, the telescopic locking mechanism drives the connecting block 7 and the clamping rod 3 to move intermittently downward or upward and can fix the sliding position of the connecting block 7.

[0041] The working principle of this utility model is as follows: The fishing line 24 is passed through the axially penetrating sleeve 1 of this device, passing through the through hole of the lever 5, between the rotating pressure block 6, in the middle of the telescopic locking mechanism, and through the through hole of the connecting block 7. A fishhook and a sinker are attached to the bottom end of the fishing line 24 (adding a sinker can, if needed, further facilitate the interaction between the rotating pressure block 6 and the telescopic locking mechanism). The float 23 is installed outside the lever 5 (the lever 5 can also be a rod-type float 23; the bottom of the rod-type float 23 is fixedly connected to the rotating pressure block 6 inside the sleeve 1; in this structure, the rod-type float 23 needs to be connected to the rotating pressure block 6). The solid or rod-type float 23 has a structure that is fixedly connected to the rotating pressure block 6. For example, the bottom of the rod-type float 23 has a connecting rod that extends into the casing 1. The connecting rod is fixedly connected to the pressure block. Therefore, the lever 5 can be used for the float 23 or can be set separately. The telescopic locking mechanism utilizes the automatic telescopic locking structure of a press-to-retract ballpoint pen (its structural principle can be referred to, but is not limited to, the Zebra JJ15 press-to-retract ballpoint pen transparent model). By flipping the lever 5, the rotating pressure block rotates and exerts a downward force on the telescopic locking mechanism, thereby causing the telescopic locking mechanism to drive the clamping rod 3 to axially extend and retract inside the casing 1. In the installed state, when the clamping rod 3 moves downward, the elastic clamp 4 moves down along the inclined structure 2 of the upper section of the casing 1 and deforms and moves in the direction of the axis of the casing 1 to clamp the fishing line 24, preventing the device from slipping off the fishing line 24. Then, the hook connected to the device is cast into the water. Float 23 floats on the surface, and lever 5 is coaxial with casing 1. When adjusting the hook's depth according to the fishing conditions, the angler pulls the fishing line 24, causing casing 1 to deflect relative to float 23. Due to buoyancy, float 23 and lever 5 remain in a relatively vertical position. The rotating pressure block 6 exerts a downward force on the telescopic locking mechanism, causing the telescopic locking mechanism to move the line clamping rod 3 upward. Under elastic stress, the elastic clamp 4 rises along the tilting mechanism, unfolding to both sides to release the fishing line 24. At this point, the angler can pull upward (keeping the line pulled so casing 1 remains tilted) to adjust the hook's depth or release fish into the water. When the fishing line 24 is released into the water, due to the principle of the telescopic locking mechanism, the casing 1 is reset and coaxial with the float 23, the rotating pressure block 6 is reset, and the elastic clip 4 is still not clamping the fishing line 24. After adjusting the position of the hook in the water, pull the fishing line 24 again. Use the rotating pressure block 6 to press down the telescopic locking mechanism again, so that the clamping rod 3 drives the elastic clip 4 to move downward. The elastic clip 4 moves down along the inclined structure 2 of the upper section of the casing 1 and deforms and moves in the direction of the axis of the casing 1 to clamp the fishing line 24, preventing the device from slipping off the fishing line 24. The relative position of the hook and the device is fixed, and you can enter the fishing state. If you need to continue to adjust the height of the hook, repeat the above actions.

[0042] In this embodiment, as Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the telescopic locking mechanism includes a sliding pawl sleeve 8 below the rotating pressure block 6, a locking member 9 that cooperates with the sliding pawl sleeve 8, and an elastic member 10 located at the bottom of the locking member 9. The sliding pawl sleeve 8 and the locking member 9 are axially provided with through holes through which the clamping rod 3 can pass. An axial sliding structure is provided between the sliding pawl sleeve 8 and the housing 1. The lever 5 rotates to drive the rotating pressure block 6 to make the sliding pawl sleeve 8 slide up and down, causing the locking member 9 to rotate intermittently. The bottom of the locking member 9 is provided with first magnetic members 11 spaced apart, and the magnetic poles of adjacent first magnetic members 11 are opposite. The connecting block 7 is provided with a second magnetic member 12 near the bottom of the locking member 9, which is opposite in position to the first magnetic members 11 and has opposite magnetic poles.

[0043] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the axial sliding structure includes a radially arranged groove 13 on the sliding pawl sleeve 8 and a radially arranged guide rail 14 on the inner wall of the sleeve 1. The bottom of the sliding pawl sleeve 8 is provided with a first helical tooth 15 in the circumferential direction, the upper part of the locking member 9 is provided with a second helical tooth 16 that cooperates with the bottom of the sliding pawl sleeve 8 in the circumferential direction, and the bottom of the guide rail 14 is provided with a third helical tooth 17 that cooperates with the second helical tooth 16.

[0044] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13As shown, the working principle of the telescopic locking mechanism is similar to the automatic telescopic locking structure of a press-to-retract ballpoint pen. One type of telescopic locking mechanism operates as follows: In the initial state, the axis of lever 5 and housing 1 are on the same plane. The elastic element 10 supports the locking element 9 located below the guide rail 14. The second helical tooth 16 and the third helical tooth 17 abut against each other. The sliding groove 13 of the sliding pawl sleeve 8 is located on the guide rail 14. The end of the first helical tooth 15 of the sliding pawl sleeve 8 contacts the inclined surface of the second helical tooth 16 of the locking element 9, but does not slide into the bottom of the inclined surface of the second helical tooth 16 (this state can be designed according to the locking element 9, spring length, and sliding pawl sleeve 8; the spring force is less than the force required to tilt the housing 1 by pulling the fishing line 24; the spring force only needs to support the locking element 9). When lever 5 rotates (or when the device is in water, pulling the fishing line 24 causes the housing 1 to rotate), the mechanism... When the device is in motion, the rotating pressure block 6 presses down on the sliding claw sleeve 8 and moves it downward. Under the action of the downward pressure and the elastic stress of the elastic element 10, the end of the first helical tooth 15 slides towards the bottom of the inclined surface of the second helical tooth 16. As the sliding claw sleeve 8 moves axially along the guide rail 14, the inclined surface of the second helical tooth 16 of the locking element 9 is squeezed by the inclined surface of the first helical tooth 15. The second helical tooth 16 of the locking element 9 slides out from the third helical tooth 17 of the guide rail 14 and rotates. When the lever 5 is reset, or when the device is in the water and the fishing line 24 is loosened so that the sleeve 1 is reset and parallel to the lever 5, the rotating pressure block 6 is reset, the sliding claw sleeve 8 moves upward, and the second helical tooth 16 of the locking element 9 changes angle. The second helical tooth 16 of the locking element 9 is engaged with the other adjacent third helical tooth 17 on the guide rail 14 and abuts against it. At this time, the rotation angle of the locking element 9 has been fixed.

[0045] The purpose of rotating the locking member 9 by means of the telescopic locking mechanism is to allow the first magnetic element 11 at the bottom of the locking member 9 to interact with the second magnetic element 12 at the bottom of the connecting block 7. When the locking member 9 rotates to a certain angle, the magnetic poles of the first magnetic element 11 and the second magnetic element 12 are opposite, as shown below. Figure 8 As shown, the first magnetic component 11 and the second magnetic component 12 generate an attractive force, and the locking component 9 is supported upward by the elastic component 10. Therefore, under the action of magnetic force, the connecting block 7 is attracted to the bottom of the locking component 9. The connecting block 7 is threadedly connected to the lower section of the clamping rod 3. At this time, the elastic clamping piece 4 is in an open state on the inclined structure 2 and does not clamp the fishing line 24. However, when the magnetic poles corresponding to the first magnetic component 11 and the second magnetic component 12 are the same, as... Figure 9 As shown, the first magnetic component 11 and the second magnetic component 12 generate a repulsive force, causing the locking component 9 to repel the connecting block 7 from moving axially downwards. The connecting block 7 then drives the line clamping rod 3 to move downwards, causing the elastic clamping piece 4 to fold inwards along the inclined structure 2 and clamp the fishing line 24. Driven by the lever 5, the locking component 9 can slide and rotate under the action of the third helical tooth 17 on the guide rail 14, thereby causing the elastic clamping piece 4 to open or clamp the fishing line 24, thus realizing the operation of adjusting the depth of the fishhook in the water.

[0046] When using the device, the angler adjusts the elastic clip 4 to clamp the fishing line 24, and then casts the device and the hook into the water. When it is necessary to adjust the depth of the hook in the water according to the fishing conditions, the angler pulls the fishing line 24 to adjust the depth of the hook in the water.

[0047] In this embodiment, the inclined structure 2 is integrally formed with the housing 1. An inclined countersunk hole is formed in the middle of the inclined structure 2. The hole is square (or elliptical or other non-circular openings). The clamping rod 3 has a corresponding square segment on its body, thereby ensuring that the clamping rod 3 only moves axially up and down inside the housing 1 without rotating. Since the connecting block 7 is threadedly connected to the lower section of the clamping rod 3, the connecting block 7 will also not rotate. Therefore, when the locking member 9 slides and rotates, the first magnetic member 11 and the second magnetic member 12 can attract or repel each other, thereby driving the clamping rod 3 to move axially up and down. To prevent the threaded connection between the connecting block 7 and the clamping rod 3 from loosening, a fastener 25 is also threadedly connected to the bottom of the connecting block 7 to prevent the connecting block 7 from falling off. The first magnetic member 11 and the second magnetic member 12 are both magnets, which are embedded in the locking member 9 and the connecting block 7, respectively.

[0048] It should be noted that the magnetic force generated by the magnet is greater than the elastic force of the spring. For example, the spring constant can be in the range of 0.05 N / m to 0.1 N / m, and the magnet can be a general household magnet or a small permanent magnet, with a magnetic force between 0.01 Tesla and 0.05 Tesla, depending on actual operation. Furthermore, although this device is used in water, the distance between the locking element 9 and the connecting block 7 is relatively close, so the water resistance on the magnetic force generated by the magnet is negligible. Additionally, since this device is connected to the float 23, it is submerged in shallow water. Under normal water conditions, mud or sludge will not enter the casing 1 and cause blockage of internal parts. This device can also be cleaned promptly after multiple fishing trips. Practical operation has shown that it fully meets the needs of daily fishing. Three or four pieces of the first magnetic element 11 and the second magnetic element 12 can be arranged at intervals at the bottom of the locking element 9 and the connecting block 7, respectively.

[0049] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, there are two rotating pressure blocks 6, and the lever 5 includes a first support rod 18 and a second support rod 19 arranged symmetrically. The upper ends of the first support rod 18 and the second support rod 19 are connected, and their bottoms are respectively connected to the two rotating pressure blocks 6 inside the casing 1. In this embodiment, the float 23 can be fixed to the upper ends of the first support rod 18 and the second support rod 19.

[0050] Preferably, the top side of the sliding pawl sleeve 8 is provided with a mounting base 20, and the rotating pressure block 6 is located on the mounting base 20. The bottom of the rotating pressure block 6 is a flat surface that fits against the mounting base 20, or the rotating pressure block 6 is an eccentric cam. Figure 6 , Figure 7 As shown, the bottom of the rotating pressure block 6 is flat. When the device enters the water, the float 23 pulls the lever 5 vertically, and the casing 1 hangs freely on the same axis as the lever 5. At this time, the bottom of the rotating pressure block 6 is in contact with the mounting base 20 on the top of the sliding claw sleeve 8 to determine the initial position of the device. When the lever 5 and the casing 1 are relatively tilted, the rotating pressure block 6 will exert downward pressure on the sliding claw sleeve 8 when it rotates relative to the mounting base 20. In order to facilitate the rotation of the rotating pressure block 6 within the casing 1, a rotating cavity 26 matching the rotating pressure block 6 is also provided inside the casing 1. The rotating cavity 26 is a transverse columnar structure to meet the rotation radius requirements of the rotating pressure block 6.

[0051] In this embodiment, as Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a first plug 21 and a second plug 22 with through holes are respectively provided at both ends of the casing 1. During daily use, large foreign objects are prevented from entering the device, which serves as a protection. The elastic element 10 is set between the second plug 22 and the connecting block 7. During use, the fishing line 24 passes through the through holes of the first plug 21 and the second plug 22.
