Auxiliary tool for low-voltage aluminum-plastic wire to penetrate through square elbow

Abstract

The invention discloses an auxiliary tool for a low-voltage aluminum-plastic wire to penetrate through a square elbow. The auxiliary tool comprises a support and a roller set arranged on the support. The support comprises an L-shaped rod, a first rotating shaft fixedly arranged at one end of the L-shaped rod, a fourth rotating shaft fixedly arranged at the other end of the L-shaped rod, a third rotating shaft fixedly arranged at the bent position of the L-shaped rod and a second rotating shaft arranged between the first rotating shaft and the third rotating shaft, and the second rotating shaft is fixedly connected with the L-shaped rod. The roller set comprises a first roller arranged on the first rotating shaft, a second roller arranged on the second rotating shaft, a third roller arranged on the third rotating shaft and a fourth roller arranged on the fourth rotating shaft. According to the invention, threading can be easily carried out, direct contact between a lead and a sharp surface is avoided, the problem of damage to a wire insulation layer when the lead is threaded in the PVC square elbow is solved, the installation quality of a low-voltage user meter is improved, the power supply reliability and the customer satisfaction are guaranteed, the threading speed is high, the whole process only needs to be operated by a single person, the structure is simple, and the device can be manufactured and is convenient to carry and use.

Description

technical field [0001] The invention relates to the technical field of electric power engineering auxiliary tooling, in particular to an auxiliary tool for passing a low-voltage aluminum-plastic wire through a right-angle elbow. Background technique [0002] During the installation and connection work of low-voltage scattered household meters, the inlet and outlet lines of the meter box are inseparable from the laying of PVC pipes. The construction personnel generally use the direct pulling wire threading method on site, but because the overlapping interface of the inner corner of the PVC right angle elbow is vertical and sharp, pulling When conducting wires, the insulation layer is easily damaged, stuck and difficult to pull, which reduces the insulation performance, and the wires are prone to aging and short-circuit faults. Keeping the wire from coming into direct contact with sharp surfaces is key when threading. Contents of the invention [0003] The technical problem...
