Transition structure of 3D printing lure and lure using transition structure

Abstract

The transition structure of the 3D printing lure and the lure using the transition structure comprise a reinforcing part with the thickness increased, a shell part is arranged on the lower portion of the reinforcing part, a local reinforcing plate is arranged between the reinforcing part and the shell part, one end of the local reinforcing plate and the outer edge of the reinforcing part are integrally arranged, and the other end of the local reinforcing plate and the outer edge of the shell part are integrally arranged. The local reinforcing plate is gradually thinned according to the thickness in the direction away from the reinforcing piece. According to the artificial bait integrated forming mode obtained through 3D printing, due to the fact that the thickness change between the reinforcing part and the shell part is large, tearing is likely to happen in the machining process, the local reinforcing plate is arranged, and on the premise that the appearance structure of the printed artificial bait is affected as little as possible, the connecting strength can be guaranteed; therefore, the artificial bait can be used on a 3D printed integrated artificial bait structure.

Description

Technical Field

[0001] The present application relates to a transition structure of a 3D printed lure and a lure using the transition structure. Background Art

[0002] Lures are mimics used to simulate small fish and attract the interest of large fish or other predators by controlling the swimming posture. The accessories of lures generally include an external shell, on which a fishhook is hung to achieve the effect of fishing, and a counterweight is arranged inside the external shell to maintain or control the swimming posture. Since most lures are assembled now, their counterweights are also mostly assembled into the lures. For lures obtained by 3D printing, since they are formed in an integrated manner, there is no basis for internal assembly of the counterweight, and the counterweight structure needs to be redesigned and distributed. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a transition structure of a 3D printed lure, including a reinforcing member with increased thickness, a shell member arranged at the bottom of the reinforcing member, a local reinforcing plate arranged between the reinforcing member and the shell member, one end of the local reinforcing plate is integrated with the outer edge of the reinforcing member, and the local reinforcing plate is arranged in a gradually thinning thickness in the direction away from the reinforcing member. The present application proposes a method of obtaining an integrated lure by 3D printing. Since the thickness between the reinforcing member and the shell member varies greatly, tearing is likely to occur during the processing. The local reinforcing plate can ensure the strength of the connection while minimizing the impact on the external structure of the printed lure, so that it can be used on the integrated lure structure of 3D printing.

[0004] Preferably, the cross section of the local reinforcement plate is an inner R angle shape.

[0005] On the other hand, the present application also proposes a lure with a transition structure, including an integrated shell, an integrated force pull ring at the rear of the integrated shell, and several integrated hook hanging rings at other parts of the integrated shell; the local reinforcement plate is arranged between the integrated shell and the force pull ring and between the integrated shell and the hook hanging ring. The present application realizes the functionalization of the lure itself by arranging a force pull ring and a hook hanging ring in coordination on the integrated shell, but whether it is the force pull ring or the hook hanging ring, it is very easy to crack during the processing process due to its external and thickened characteristics during the 3D printing process. The use of the local reinforcement plate completely eliminates this problem.

[0006] Preferably, a rear counterweight is provided at the rear of the integrated housing, and an auxiliary counterweight is fixedly provided at the front and / or middle of the integrated housing. The rear counterweight of the present application is arranged in cooperation with the force-applying pull ring (connected to the fishing line), so that a stable force-applying part is formed at the force-applying part, which is similar to the role of a rotating shaft, so that when the lure moves in the water, it can perform movement postures such as left and right shaking under the premise of stabilizing the tail.

[0007] Preferably, the rear counterweight block and the auxiliary counterweight block respectively include a raised portion located in the middle, and the raised portion is connected to the integrated shell.

[0008] Preferably, the raised portion includes a counterweight body located in the middle, an outer annular plate is arranged on the outer side of the counterweight body, the thickness of the outer annular plate gradually becomes thinner in the direction away from the counterweight body, and the outer annular plate is fixedly connected to the integrated shell. The present application can better complete the edge transition by arranging the outer annular plate on the outer side of the raised portion and then assisting with the local reinforcement plate, further ensuring the connection strength of the edge transition.

[0009] Preferably, a local reinforcement plate is provided between the raised portion and the integrated housing.

[0010] Preferably, the auxiliary counterweight block is a front counterweight block arranged at the front and a middle counterweight block arranged at the middle, or the auxiliary counterweight block is a middle counterweight block arranged at the middle.

[0011] Preferably, the one-piece shell part located at the force-applying pull ring part and the lower part is a TC4 titanium alloy plate with a thickness of 1-1.3 mm; the one-piece shell part at other parts is a TC4 titanium alloy plate with a thickness of 0.8-1 mm.

[0012] Preferably, a plurality of outlet holes for outlet internal powder are provided on the integrated housing; sealing nuts or welding piles are provided on the outlet holes;

[0013] The number of the outlet through holes is two, and the outlet through holes are arranged on the rear counterweight block and / or the auxiliary counterweight block.

[0014] This application can bring the following beneficial effects:

[0015] 1. In the present application, for the one-piece forming method of the lure obtained by 3D printing, due to the large thickness variation between the reinforcement member and the shell member, tearing is prone to occur during the processing. The provision of a local reinforcement plate can ensure the strength of the connection while minimizing the impact on the external structure of the printed lure, so that it can be used on the 3D printed integrated lure structure.

[0016] 2. The present application realizes the functionality of the lure itself by providing a force-applying pull ring and a hook hanging ring that cooperate with each other on the one-piece shell. However, both the force-applying pull ring and the hook hanging ring are very prone to cracking during the 3D printing process due to their external and thickened characteristics. The use of a local reinforcement plate completely eliminates this problem.

[0017] 3. The present application can better complete the edge transition and further ensure the connection strength of the edge transition by setting an outer annular plate on the outer side of the raised portion and then assisting with a local reinforcement plate.
