Therefore, the direction terms used are used to illustrate and understand the utility model, and are not used to limit the utility model.

[0030] Please refer to Figures 1-3 As shown in the figure, the utility model provides a reverse bottom running weight 100, which comprises a main body 1, a line passing buckle 2, a connecting piece 3 and a counterweight 4.

[0031] The main body 1 is made of plastic material, which comprises a main body shell 11 with one end open and the other end closed and hollow, and a line passing groove 12 formed by inwardly recessing from the outer peripheral side of the main body shell 11.

[0032] The line passing buckle 2 is inserted into the line passing groove 12 and is clamped with the main body shell 11 to form a detachable fixed connection. The line passing buckle 2 and the line passing groove 12 together form a line passing channel, and the two ends of the line passing channel are respectively led out by the closed end of the main body shell 11 and the side surface of the main body shell 11. In this embodiment, the line passing groove 12 is designed in an arc structure to realize the leading out of the two ends of the line passing channel from two directions.

[0033] The line passing channel is used for passing the fishing line, and the fishing line can slide freely in the line passing channel.

[0034] The connecting piece 3 covers the open end of the main body shell 11 and cooperates with the main body shell 11 to form a sealed air cavity, so as to make the main body 1 float.

[0035] The counterweight 4 is fixed to the side of the connecting piece 3 away from the main body shell 11, so that the whole anti-bottom sinker 100 has an upper light and lower heavy structure similar to a "tilt" structure.

[0036] Please combine Figure 4 As shown, the subline 200 of the hook group passes through the wire passing channel, and the space bean 300 is installed on the subline 200, so that the space bean 300 is located between the fish hook 400 and the anti-bottom sinker 100. After entering the water, the anti-bottom sinker 100 sinks to the bottom of the water and stands in a state that the counterweight 4 is below and the main body 1 is above, so as to be less affected by the water flow, effectively improving the reliability of the eel fishing method. At the same time, due to the length limitation of the subline 200 and the upward pulling force of the main line 500, the fish hook 400 on the subline 200 is suspended upward near the upper side of the anti-bottom sinker 100. Moreover, the space bean 300 also plays a limiting role on the fish hook 400. By extending and adjusting the length of the subline 200, the distance between the fish hook 400 and the anti-bottom sinker 100 is adjusted, so that the fish hook 400 is suspended in the preset distance range above the anti-bottom sinker 100, and it is easier to catch fish. At the same time, because the subline 200 can slide freely in the wire passing channel, when the fish bites, even if the action amplitude is small, the subline 200 will also slide in the wire passing channel, and the biting signal is transmitted to the float through the fishing line, so as to improve the efficiency and increase the fish catching rate. The wire passing buckle 2 is detachably fixedly connected to the main body 1, and is suitable for various line groups of fish hooks that users already have. The wire passing buckle 2 can be directly folded to realize the installation or replacement of the line group without cutting the line or binding the line, so as to improve the user experience effect.

[0037] In this embodiment, specifically, the wire passing buckle 2 includes a buckle body 21 matched with the wire passing groove 12, two first clamping walls 22 protruding from opposite sides of the top end of the buckle body 21, two extension walls 24 extending downward from the bottom end of the buckle body 21 and spaced from each other to form a wire passing opening 23, and two second clamping walls 25 protruding from the sides of the two extension walls 24 away from each other.

[0038] The buckle body 21 is recessed to form a recess 211 on the side close to the main body shell 11, and the buckle body 21 abuts to the groove bottom of the wire passing groove 12 to encapsulate the recess 211 into the wire passing channel. The wire passing opening 23 is in communication with the wire passing channel and leads one end of the wire passing channel out of the side surface of the main body shell 11, that is, leads out along the axis direction perpendicular to the main body shell 11.

[0039] The first clamping wall 22 extends along the axial direction of the main body shell 11, and the second clamping wall 25 extends along the axial direction perpendicular to the main body shell 11.

[0040] Corresponding to the structure of the wire passing clamping buckle 2, the wire passing groove 12 further comprises two first clamping grooves 13 and two second clamping grooves 14 formed by the outer periphery of the main body shell 11.

After the sub-wires of the wire group are placed straight in the wire passing groove 12, the two first clamping walls 22 are aligned with the two first clamping grooves 13 by pinching the two second clamping walls 25 and then sliding downward, the first clamping wall 22 is clamped in the first clamping groove 13, and then the second clamping wall 25 is pushed into the wire passing groove 12 and aligned with the second clamping groove 14, and the second clamping wall 25 is released, and then it is elastically deformed due to no external force pressing, so as to be clamped in the second clamping groove 14, so that the fishing line is encapsulated in the wire passing channel and can freely slide in the wire passing channel.

[0042] Because the first clamping wall 22 extends along the axial direction parallel to the main body shell 11, and the second clamping wall 25 extends along the axial direction perpendicular to the main body shell 11. The structure of the two directions realizes the clamping of the wire passing clamping buckle 2 and the main body 1.

The main body shell pipe wall 15 abuts against the clamping extension pipe wall 26 and together forms a guide pipe 20, and the guide pipe 20 communicates with the wire passing channel and leads the other end of the wire passing channel out of the closed end of the main body shell 11.

[0044] In this embodiment, the main body 1, the wire passing buckle 2, the connecting piece 3 and the weight block 4 are assembled into a capsule shape, and the lower weight and the upper light form a tumbler structure.

[0045] The connecting piece 3 includes a connecting piece body 31 arranged on the open end (bottom end) of the main body shell 11, a connecting wall 32 in the form of a ring extending from the side of the connecting piece body 31 close to the main body shell 11, and a glue groove 33 recessed from the side of the connecting piece body 31 close to the main body shell 11. The connecting wall 32 is inserted into the main body shell 11 to form a sealed engagement and make the connecting piece body 31 abut against the open end of the main body shell 11, the glue groove 33 is located on the outer circumferential side of the connecting wall 32 and extends to the outer periphery of the connecting piece body 31, and the glue groove 33 is filled with glue to further fix the connecting piece body 31 and the main body shell 11.

[0046] The way of fixing the weight block 4 to the main body 1 by the connecting piece 3 is not limited, and in this embodiment, the connecting piece 3 further includes a connecting column 34 extending downward from the side of the connecting piece body 31 away from the main body shell 11. The weight block 4 is provided with a connecting hole 41 penetrating through the main body shell 11 along the axial direction, and the connecting column 34 is inserted into the connecting hole 41 to form an interference fit, thereby fixing the weight block. More preferably, glue is applied at the bottom end of the connecting hole 41 to further glue and fix the connecting column 34 and the fitting block.

[0047] In this embodiment, the weight block 4 is made of lead, and of course can also be made of other high-density metals.

[0048] More preferably, the wire outlet directions of the two ends of the wire passing channel are perpendicular to each other, that is, the wire outlet directions from the two positions of the side surface and the top of the main body 1 are perpendicular to each other. At this time, when the sub-line 200 passes through the wire passing channel, the wire passing channel is equivalent to a 90-degree angle guide turn, and at the same time, the other end of the sub-line 200 is subjected to the upward traction force of the main line 500 and the float, and the length of the sub-line 200 and the positioning of the space bean, so that the fish hook 400 on the sub-line 200 is always close to the anti-bottom running sinker 100 and stands above it, and the bottom fishing reliability and stability are higher.
