Description

Technical Field

[0001] This application relates to an integrated counterweight structure and a fishing lure using the counterweight structure. Background Art

[0002] A fishing lure refers to a mimic bait used to simulate small fish and arouse the interest of big fish or other predators through swimming pose control, etc. The accessories of a fishing lure generally include an outer shell, and a fishhook is hung on the outer shell to achieve the function of fishing. A counterweight is arranged inside the outer shell to maintain or control the swimming pose. Since most current fishing lures are assembled, their counterweights are mostly assembled into the fishing lures. For fishing lures obtained by 3D printing, since they are formed in one piece, there is no basis for internal assembly of the counterweight, and the counterweight structure needs to be redesigned and distributed. Summary of the Utility Model

[0003] To solve the above problems, on the one hand, this application proposes an integrated counterweight structure, which includes a bottom support plate. A bottom counterweight block is fixedly arranged at the tail of the bottom support plate, and an auxiliary counterweight block is fixedly arranged at the front part and / or the middle part of the bottom support plate. By fixedly arranging the bottom counterweight block at the tail of the bottom support plate in this application, a base point during movement can be formed, providing a structural basis for the stable movement of the fishing lure in water. For the auxiliary counterweight blocks at the front part or the middle part, different settings can be made according to the requirements of the movement posture of the fishing lure.

[0004] Preferably, the bottom counterweight block and the auxiliary counterweight block respectively include a convex part located in the middle, and the convex part is connected to the bottom support plate.

[0005] Preferably, the convex part includes a counterweight body located in the middle. An outer annular plate is arranged on the outer side of the counterweight body, and the thickness of the outer annular plate gradually becomes thinner along the direction away from the counterweight body. The outer annular plate is fixedly connected to the bottom support plate.

[0006] Preferably, a strengthening connecting plate is arranged between the convex part and the bottom support plate, and the thickness of the strengthening connecting plate gradually becomes thinner along the direction away from the convex part. By arranging the outer annular plate on the outer side of the convex part and supplementing it with the strengthening connecting plate in this application, better edge transition can be completed, and further ensure the connection strength of the edge transition.

[0007] Preferably, the cross-section of the strengthening connecting plate is in the shape of an inner R angle.

[0008] On the other hand, the present application also proposes a fishing lure using the above integrated counterweight structure, including an integrated housing. An integrated force-applying pull ring is provided at the rear of the integrated housing, and a number of integrated hook hanging rings are provided at other parts of the integrated housing. The lower part of the integrated housing forms a bottom support plate; the bottom counterweight is arranged at a position corresponding to the force-applying pull ring.

[0009] Preferably, the auxiliary counterweight includes a front counterweight arranged at the front part and a middle counterweight arranged at the middle part, or the auxiliary counterweight is a middle counterweight arranged at the middle part.

[0010] Preferably, reinforcing connecting plates are respectively arranged between the force-applying pull ring and the hook hanging rings and the integrated housing. The thickness of the reinforcing connecting plate gradually becomes thinner along the direction away from the convex part.

[0011] The cross-section of the reinforcing connecting plate is in the shape of an inner R corner. In the present application, the functions of the fishing lure itself are realized by arranging a force-applying pull ring and hook hanging rings which are cooperatively arranged on the integrated housing. However, whether it is the force-applying pull ring or the hook hanging ring, during the 3D printing process, due to their external and thickened settings, they are very prone to cracking during the processing. The use of the reinforcing connecting plate completely eliminates this problem.

[0012] Preferably, the bottom support plate is a TC4 titanium alloy plate with a thickness of 1 - 1.3 mm; the thickness of the other parts of the integrated housing is a TC4 titanium alloy plate with a thickness of 0.8 - 1 mm. The present application uses TC4 titanium alloy plates with different thicknesses, making the present application have better tensile properties. Moreover, due to the use of the 3D printing integrated setting method, it is very easy to realize the structural setting of different thicknesses.

[0013] Preferably, a number of lead-out through holes for leading out the internal powder are arranged on the integrated housing; a sealing nut or a welding build-up is arranged on the lead-out through hole.

[0014] There are two lead-out through holes, and the lead-out through holes are arranged on the bottom counterweight and / or the auxiliary counterweight.

[0015] The present application can bring the following beneficial effects:

[0016] 1. The present application uses the tail of the bottom support plate to fixedly arrange the bottom counterweight, which can form a base point during movement and provide a structural basis for the stable movement of the fishing lure in water. For the auxiliary counterweights at the front or middle part, different setting methods can be carried out according to the requirements of the movement posture of the fishing lure.

[0017] 2. In the present application, by arranging an outer annular plate on the outside of the convex part and assisting with the reinforcing connecting plate, the edge transition can be better completed, and the connection strength of the edge transition can be further ensured.

[0018] 3. This application uses TC4 titanium alloy plates with different thicknesses, enabling the application to have better tensile properties. Moreover, due to the use of the 3D printing integrated setting method, it is very easy to achieve the structural setting with different thicknesses. BRIEF DESCRIPTION OF THE DRAWINGS
