Hand-operated cable terminal turn-back binding device

Abstract

The invention discloses a hand-operated cable terminal turn-back binding device, which comprises a binding tool and a wire clamp. The binding tool comprises a fixed frame and a movable frame. The fixed frame comprises a rack and a supporting base. The movable frame comprises a sliding block, a movable pressing base and a driving mechanism. The movable pressing base is opposite to the supporting base. The driving mechanism comprises a rocker arm, a driving gear, a driving block, a locking block, a first torsional spring and a second torsional spring. The rocker arm and the driving gear are bothcoaxially hinged to the sliding block. The driving gear is located on the right side of the rack and meshed with the rack. The driving block is hinged to the rocker arm and meshed with the driving gear, and the meshing position is located at the lower right of the hinging position. The locking block is hinged to the sliding block and meshed with the driving gear, and the meshing position is located at the lower left of the hinging position. The wire clamp is a split wire clamp of which the two split bodies can be connected oppositely, one split body of the split wire clamp can be connected with the movable pressing base, and the other split body of the split wire clamp can be connected with the supporting base. The beneficial effects are that turn-back cables can be quickly pressed and fixed together in a labor-saving manner, the operation is convenient and the fixation is firm.

Description

technical field [0001] The invention relates to the field of power tools, in particular to a hand-cranked cable terminal back binding device. Background technique [0002] It is very important to ensure the safe and stable operation of the power grid in today's society. Cables are erected on utility poles or buildings through street yards, and the fixing of cable terminals is generally done by pressing and fixing the cable terminals that bypass street yards and turn back together; at present, construction workers usually use manpower or simple Traditional methods such as tools compress the separated return cables together and then use binding wires to bind and fix the compressed return cables. Because the diameter of the cable is relatively thick, it is difficult for workers working at heights to press the cables back together only by manpower or simple tools, and the cable itself is very elastic when it is bent, and it is easy to bounce or slip off from the hands or simple...

AI Technical Summary

Problems solved by technology

Because the diameter of the cable is relatively thick, it is difficult for workers working at heights to press the cables back together only by manpower or simple tools, and the cable itself is very elastic when it is bent, and it is easy to bounce or slip off from the hands or simple tools. Increased the difficulty of construction

Binding wires are generally thin aluminum metal wires. Tightening the cables will reduce the insulation of the cables and easily cause damage to the cable sheath. Moreover, there is no uniform standard for the binding method, which is very random, which makes it difficult to ensure the firmness of the binding of the cable terminals. , Turning back the cable is easy to loosen and fall off from the street yard, which brings potential safety hazards; at present, there are also some wire tightening devices, although they can basically solve the above problems, but they have the following problems: they need to use external tools (such as electric tools) during operation. wrench or manual wrench), the operation process is complicated, it is inconvenient to carry when using an electric wrench, and the cost is high, and the operation speed is too slow and the efficiency is low when using a manual wrench
