Technical Field

[0001] The utility model relates to the technical field of injection molding wire drawing accessories, in particular to a curved conduit structure used for the end of a wire drawing. Background Art

[0002] Cables play a key supporting and fixing role in various engineering applications. Traditional cable end bends are mostly made of metal materials, such as steel or aluminum alloy.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Example 1

[0018] like Figure 1 , Figure 2 As shown, a specific embodiment of a bending tube structure for a wire pulling end described in the utility model comprises: a bending tube body 1, a wire core hole for fitting a wire pulling core is arranged in the bending tube body 1, a positioning slot 2 is fixedly installed on the left side of the bending tube body 1, the positioning slot 2 comprises two truncated cone-shaped structures arranged on the outer side of the bending tube body 1, an opening slot 3 is opened on the upper part of the bending part of the bending tube body 1, and a reinforcing rib 4 is fixedly arranged on the lower part of the bending part of the bending tube body 1.

[0019] An outer shell hole 6 is opened at the right end of the wire core hole of the bent pipe body 1, and the outer shell hole 6 is used to mount the wire pulling sleeve to improve the strength and stability of the structure. A guide hole 7 is opened on the right side of the outer shell hole 6. The inner diameter of the guide hole 7 is larger than the inner diameter of the outer shell hole 6. A truncated cone-shaped transition opening 8 is opened at the boundary between the outer shell hole 6 and the guide hole 7. The design of the guide hole 7 and the truncated cone-shaped transition opening 8 makes the installation of the wire pulling sleeve smoother and reduces the friction and resistance during the installation process, so as to facilitate the smooth installation of the wire pulling sleeve.

[0020] A tapered opening 5 is provided at the left end of the wire core hole of the curved pipe body 1 to reduce friction and resistance of the wire during use.

[0021] In this solution, the curved conduit structure uses high-strength engineering plastics as the main material and is formed in one piece by injection molding. The process is simple, the production efficiency is high, and the product consistency is good.

[0022] The working principle of the utility model: during the installation process, the wire puller inserts the wire puller sleeve into the outer shell sleeve hole 6 and installs the wire puller core into the wire core hole through the guide hole 7 and the truncated cone transition port 8. The design of the guide hole 7 and the truncated cone transition port 8 makes the installation of the wire puller sleeve smoother and reduces the friction and resistance during the installation process. Finally, the bent conduit structure and the wire pulling device or structure are positioned and fixed through the positioning slot 2 to ensure that the direction and position of the wire puller are stable and reliable; through the optimized design of the bent conduit structure, such as the reinforcing rib 4, the stability and strength of the structure are enhanced, so that it can withstand the pulling force of the wire and maintain a stable shape, and the open slot 3 can facilitate injection molding, reduce production costs, and improve production efficiency.
