Title:
SELF-LOCKING CABLE FASTENING HOLDER
Document Type and Number:
WIPO Patent Application WO/2018/133696
Kind Code:
A1
Abstract:
A self-locking cable fastening holder comprises a U-shaped male holder (21) and a female holder (22). A first cable holding part (211) is arranged at a bent portion of the U-shaped male holder (21). A second cable holding part (221) is arranged at the female holder (22). The first cable holding part (211) and the second cable holding part (221) can cooperate to hold a cable. Locking rods (212) are arranged at two sides of the U-shaped male holder (21), and corresponding locking holes (222) are arranged at the female holder (22). A non-return shaft (2121) is arranged at each of the locking rod (212), and a movable locking block (223) is arranged at a side each of the locking holes (222) and has a corresponding locking thread (2231). The locking block (223) abuts against a locking spring (224) such that the locking spring (224) pushes the locking block (223) against the non-return shafts (2121) of the locking rods (212), so as to limit the locking rod (212) to only move forwards and not in reverse, forming a non-return self-locking mechanism. The U-shaped male holder (21) can only move forwards, and not in reverse, in the female holder (22). When in use, the U-shaped male holder (21) is directly inserted into the female holder (22) and is automatically locked. When opening the lock, the locking spring (224) is pushed to retract the locking block (223), so as to freely remove the U-shaped male holder (21) from the female holder (22). The embodiment is simple in operation and easy to use, and is particularly suitable for use in overhead power line installation.
