[0027] The following descriptions of the embodiments refer to the attached drawings to illustrate specific embodiments of the present invention. Directional terms mentioned in the present invention, such as up, down, front, back, left, right, inside, outside, side, etc., are only referenced to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but are not used to limit the present invention.
[0028] Please refer to Figure 1-7 As shown, the utility model provides a sub-line upward clamping weight 100, comprising: a counterweight body 1 made of metal material, a line clamping colloid 2 made of flexible material fixed on the counterweight body 1, and a hook handle clamping part 3 made of flexible material.
[0029] In this embodiment, the counterweight 1 is made of lead, but it can also be made of other metals with higher density, which is feasible.
[0030] The line clamping colloid 2 is made of silicone or plastic material. The line clamping colloid 2 includes a main body 21 fixed to the top surface of the counterweight body 1, a sub-body 22 assembled on the main body 21 and detachably connected with the main body 21, and a connecting wall 23 connecting the main body 21 and the sub-body 22 and being bendable. The sub-body 22 is embedded in the main body 21 to form a clamping arrangement, and forms an interference fit with the main body 21, which is used to clamp the fishing line between the main body 21 and the sub-body 22 and form a positioning. Thus, the above structure enables the sub-line to clamp the weight 100 upward to form a structure that is heavy at the bottom and light at the top, so that the line clamping colloid 2 is located above the counterweight body 1 in the fishing position of the water flow. The section of the sub-line close to the fish hook is placed on the main body 21, and the sub-body 22 is pressed into the main body 21 to form an embedded interference fit to fix the sub-line. When clamping, the sub-line is rotated so that the hook tip of the fish hook 20 is on top, and at the same time, the line clamping colloid 2 is facing upward to be consistent with the hook tip of the fish hook 20. Due to the bottom-heavy and top-light structure of the sub-line clamping weight 100, similar to the principle of a tumbler, the hook tip of the fish hook 20 on the sub-line is at the bottom of the water and is always above the fish hook, thereby realizing the directional use of the fish hook fishing group and effectively increasing the fish catching rate. In addition, the counterweight body 1 of the sub-line clamping weight 100 effectively prevents the flowing water from washing away the fish hook on the sub-line, greatly improving the experience of fishing in flowing waters.
[0031] Specifically, in the present embodiment, the main body 21 includes a supporting body 211 fixed to the counterweight body 1 and having its circumferential side connected to one end of the connecting wall 23, two clamping walls 212 protruding upward from the opposite ends of the supporting body 211 in the axial direction, a through hole 213 penetrating the clamping wall 212 along the axial direction, a wire groove 214 formed in a depression on one side of the supporting body 211 away from the counterweight body 1, and two clamping walls 215 protruding upward from the supporting body 211.
[0032] The support body 211 is used for being fixedly connected to the counterweight body 1 .
[0033] Two ends of the wire groove 214 are respectively connected to the two through holes 213 , and the two clamping walls 215 are both located between the two clamping walls 212 and at two sides of the wire groove 214 .
[0034] The through hole 213 passes through the clamping wall 212 upward, so that the sub-line of the hook group can be installed downward into the line groove 214 through the top of the through hole 213.
[0035] The auxiliary body 22 includes a cover body 221 connected to the other end of the connecting wall 23 , two slots 222 formed by a recess on one side of the cover body 221 close to the main body 21 , and a wire pressing wall 223 located between the two slots 222 .
[0036] The cover body 221 is clamped between the two clamping walls 212 and forms an interference fit with the clamping walls 212, and the cover body 221 abuts against the supporting body 211, the two clamping walls 215 are respectively inserted into the two clamping grooves 222 to form a clamping, and the wire pressing wall 223 abuts against the bottom of the wire groove 214, thereby clamping and fixing the sub-wire.
[0037] The clamping walls 212 at both ends of the cover body 221 are locked by forming an interference fit therewith. When locking is required, press the counterweight body 1 at the bottom and the cover body 221 at the top with your hands and press them towards the center. Due to the interference fit between the two ends of the cover body 221 and the clamping walls 212, a large friction force is generated, and the fishing line will not rebound or loosen after being locked, thereby achieving the effect of locking the fishing line.
[0038] In the prior art, the state of the fish hook at the bottom of the water is lying flat, that is, the hook tip and the tail of the fish hook are in contact with the bottom of the water. When the fish comes to suck, it needs a large force to suck the fish hook from the bottom of the water into the mouth of the fish. If the fish has a small appetite or a small desire to feed when foraging, it is often impossible to successfully suck the fish hook from the bottom of the water into its mouth, so the fish catching rate is low. In this embodiment, the sub-line 10 is directional clamped by the clamping colloid 2 of the upper part of the sub-line weight 100, and its bottom is counterweighted by the counterweight body 1, forming a tumbler structure as a whole, which is heavy at the bottom and light at the top. When thrown into the water, the sub-line 100 is clamped up and the counterweight body 1 is at the bottom when it falls to the bottom of the water, and can be locked in the same direction, so as to control the orientation of the fish hook when clamping the sub-line, so as to control the hook tip of the fish hook 20 to be directional and upward under water above the tail of the hook, such as Figure 5-7 As long as the fish comes to feed, the hook can be easily and directly hung on the fish's mouth, thus catching the fish quickly and greatly improving the catching rate.
[0039] The hook handle clamping part 3 includes a hook handle clamping part body 31 fixed to the same end of the counterweight body 1 and the line clamping colloid 2, a clamping handle wall 32 protruding and extending from one end of the hook handle clamping part body 31 away from the line clamping colloid 2, a clamping handle groove 33 formed by a depression at one end of the clamping handle wall 32 away from the hook handle clamping part body 31, and a wire passing groove 34 formed by a downward depression at the top of the hook handle clamping part 3. The wire passing groove 34 penetrates the hook handle clamping part 3 along the axial direction of the hook handle clamping part 3 and is connected to the wire passing groove 34. After the sub-line 10 is assembled to the main body 21 of the line clamping colloid 2, it is assembled to the hook handle clamping part 3 through the wire passing groove 34. At this time, the hook handle of the fishhook 20 can be inserted into the clamping handle groove 33, and then the sub-line 10 is tightened and the auxiliary body 22 is pressed into the main body 21 to form a positioning, such as Figure 5-6 At this time, after the hook handle of the fish hook 20 is clamped by the hook handle clamping part 3, the hook tip of the fish hook 20 is more stably facing upward, which effectively improves the state stability of the fish hook and further improves the efficiency of catching fish.
[0040] In this embodiment, the hook handle clamping portion 3 is made of silicone or plastic material and has a certain elasticity, so that the hook handle of the fishhook 20 can be inserted into the clamping handle groove 33 to more effectively form positioning and locking.
[0041] Of course, the fishhook 20 can also be adjusted, that is, after the sub-line 10 is assembled to the main body 21 of the clamping colloid 2, it is assembled to the hook handle clamping part 3 through the wire passing groove 34. At this time, the hook handle of the fishhook 20 can be pulled out of the clamping handle groove 33 to expose a small part of the sub-line 10, and the auxiliary body 22 is pressed into the main body 21 to form a positioning, such as Figure 7 As shown, at this time, the fish hook 20 can still be in a state where the hook tip is facing upward due to the positioning effect of the counterweight body 1 and the line clamping colloid 2, and the fish hook 20 can also swing horizontally with the water flow. The swing amplitude of the fish hook 20 is achieved by controlling the length of the sub-line 10 exposed from the clamping handle groove 33, so that it is easier to enter the fish mouth within the fish's feeding range, thereby improving the efficiency of catching fish.
[0042] In this embodiment, the bottom surface of the counterweight body 1 is in an arc shape, the top surface of the counterweight body 1 is in a plane shape, the side of the clamping colloid 2 close to the counterweight body 1 is in a plane shape, and the side of the clamping colloid 2 away from the counterweight body 1 is in an arc shape, and the counterweight body 1 and the clamping colloid 2 are assembled to form a capsule-shaped structure. The end of the hook handle clamping part body 3 close to the clamping colloid 2 is in a concave structure, and its shape matches one end of the capsule-shaped structure, which is more convenient for assembly.
[0043] In the present embodiment, a first buckling structure (not shown) is provided at one end of the hook handle clamping part body 31 close to the wire clamping colloid 2, and a second buckling structure (not shown) matching the first buckling combination is provided at one end of the wire clamping colloid 2 and / or the counterweight body 1 close to the hook handle clamping part body 31, the first buckling structure and the second buckling structure are mutually engaged and positioned, and the hook handle clamping part 3 is simultaneously glued and fixed to the wire clamping colloid 2 and the counterweight body 1 by glue to complete the assembly.
[0044] The top surface of the counterweight body 1 is also provided with a first fixing structure (not shown in the figure), and the side of the support body 211 close to the counterweight body 1 is provided with a second fixing structure (not shown in the figure) that cooperates with the first fixing structure, and the first fixing structure and the second fixing structure are assembled to form a positioning, and the counterweight body 1 and the support body 211 are fixed by glue. In this embodiment, one of the first fixing structure and the second fixing structure can be a protruding structure, and the other can be a groove structure, so as to form a snap-fit positioning.
[0045] In this embodiment, the sub-line upward clamp weight 100 further includes a disassembly hole 4 formed by the inward depression of the circumference of the clamping colloid 2, and the disassembly hole 4 is located at both the main body 21 and the auxiliary body 22. When disassembling, the hook tip of the fishhook can be inserted into the disassembly hole 4, and the sub-line upward clamp weight 100 can be pried open and taken out, which is convenient for subsequent repeated use.
[0046] Preferably, the inner side of the top of the clamping wall 212 and the surrounding side of the top of the clamping wall 215 are both set as chamfered structures. When the main body 21 and the auxiliary body 22 of the clamping colloid 2 need to be tightened, the auxiliary body 22 is introduced into the center of the main body 21 through the chamfered structure of the main body 21, which facilitates smoother tightening.
[0047] In order to improve the reliability of the line clamping, the bottom of the line groove 214 is wavy, and the side of the line pressing wall 223 close to the line groove 214 is wavy. This increases the friction between the line and the fishing line when clamping, so that there is a greater locking force when clamping, and the anti-slip effect of the fishing line is better.
[0048] In this embodiment, the main body 21, the auxiliary body 22 and the connecting wall 23 are an integrally formed structure.
[0049] Compared with the prior art, the sub-line skyward clamping weight of the utility model is designed with a counterweight body made of metal material and a line clamping colloid made of flexible material fixed on the counterweight body, thereby forming a structure that is heavy at the bottom and light at the top, so that the line clamping colloid is located above the counterweight body in the fishing position of the water flow; the line clamping colloid is designed to have a main body and a sub-body assembled on the main body, the supporting body of the main body is fixed to the counterweight body, the sub-body is embedded in the main body to form a clamp, and forms an interference fit with the main body, so as to clamp the fishing line between the main body and the sub-body and form a positioning. The section of the sub-line close to the fishhook is placed on the main body, and the sub-body is pressed into the main body to form an embedded interference fit to fix the sub-line. When clamping, the sub-line is rotated so that the hook tip of the fishhook is on top, and at the same time, the line clamping colloid is facing upward to be consistent with the hook tip of the fishhook. Due to the bottom-heavy and top-light structure of the sub-line clamping weight facing up, similar to the principle of a tumbler, the hook tip of the fishhook on the sub-line is at the bottom of the water and is always above the fishhook, thereby realizing directional use of the fishhook fishing group and effectively increasing the fish catching rate. In addition, the counterweight body of the sub-line clamping weight facing up effectively prevents the flowing water from washing away the fishhook on the sub-line, greatly improving the experience of fishing in flowing waters.
