Description

A tensioner that saves effort to turn and fixes the tail wire conveniently

technical field

The utility model relates to the field of electric power, in particular to a wire tensioner which is labor-saving in rotation and convenient in fixing tail wires.

Background technique

In the construction of overhead line laying, it is necessary to tighten the wires, which are mainly used in various types of cables such as electric power, telecommunications departments and traction wires. When using the wire tightening device for wire tightening operation, first cut a short iron wire as the tail wire of the wire tensioner, one end is fixed on the wire tensioner, the other end is wound on the wire rod, and then wound with pliers on the folded tail wire Tighten a few turns to secure. After the wire is tightened, the thread tightening operation is carried out. After the thread tightening is completed, the tail wire of the wire tensioner fixed on the rod is removed with pliers. Because the tail wire needs to be twisted and wound once every time the rod is put up, the tail wire will be distorted and deformed after repeated use several times and cannot be used any longer. It is necessary to replace the tail wire, which increases the cost. In addition, the drums used to rotate the tight thread can only drive the whole drum to rotate by rotating one end of the drum, which is time-consuming and labor-intensive.

Utility model content

The technical problem to be solved by the utility model is to provide a wire tightener that is labor-saving and convenient to fix the tail wire, so as to avoid the situation that the tail wire is twisted and deformed by repeatedly twisting and winding the tail wire. The ends rotate at the same time, and the rotation is more labor-saving.

The technical scheme adopted by the utility model to solve the above-mentioned problems is: a wire tightener that is labor-saving to rotate and convenient to fix the tail wire, including a ratchet roller, a connecting seat, a tail wire fixing piece, a rotating handle, a wire clamp, a connector and a herringbone wrench , the ratchet roller passes through the connecting seat vertically, the two sides forming an acute angle of the herringbone wrench are respectively fixed at both ends of the ratchet roller, and the two sides of the herringbone wrench fixed at both ends of the ratchet roller can drive the ratchet roller to rotate; One end of the connecting seat is horizontally fixed to the connecting head; one end of the clamp is stuck in the connecting head, and the turning handle horizontally crosses the clamping clamp and is perpendicular to the clamping clamp; the tail wire fixing part is vertically fixed on the ratchet the top of the drum. When using iron wire as the tail wire of the wire tensioner, one end is wound on the wire tensioner, and the other end is bent into a circle. It is fine if it is blocked. After the circle is bent, wind the extra piece of wire around the tail wire three times and tighten it to fix it. After the tail wire of the above shape is finished, first wrap the tail wire around the rod, and then pass the tail wire holder through the circle of the tail wire. After the thread tightening work is completed, the tail wire fixing part can be pulled out from the tail wire circle by hand. The setting of the tail wire fixing part avoids the situation that the tail wire is twisted and deformed due to repeated twisting and winding of the tail wire. In addition, the two ends of the ratchet roller are clamped in the word wrench by the word wrench. When turning the ratchet roller to tighten the thread by turning the word wrench, it is no longer to turn one end of the ratchet roller to make it roll, but to hold both ends of the ratchet roller Let it rotate at the same time, and the rotation is more labor-saving.

The range of the acute angle formed between the two edges fixed on the two ends of the ratchet cylinder on the said wrench is between 45°-70°. While ensuring that the ratchet roller can better realize the cable management operation, it can also make it easier for people to hold the herringbone wrench to turn the ratchet roller.

The handle part of the word wrench can be stretched forward and backward, and the middle part of the handle is sunken inward. The length of the grip is adjustable, and the length of the grip part can be adjusted according to the position of the installer, so that it is convenient to hold the figure wrench to turn the ratchet roller. The middle of the handle is concave to increase the comfort when holding.

Uniform textures are provided on the outer surface of the grip part of the word wrench. Increase the friction of the grip part.

The diameter of the connecting end of the tail wire fixing part and the ratchet drum is smaller than the non-connecting end of the tail wire fixing part and the ratchet drum. It is convenient to put the ring formed by twisting the tail wire on the tail wire fixing part.

The connecting bolts are vertically fixed on the ratchet cylinder, and the arc catch is fixed above the connect bolts, and the arc catch is used to wrap the outer side of the ratchet on the top of the ratchet cylinder. Prevent the ratchet from scratching foreign objects during rotation.

A spring is provided on the turning handle located between the clamps.

In summary, the beneficial effects of the utility model are:

1. The setting of the tail wire fixing parts avoids the situation that the tail wire is twisted and deformed by repeated twisting and winding of the tail wire; When threading, instead of turning one end of the ratchet roller to make it roll, hold both ends of the ratchet roller and let it rotate at the same time, which saves effort.

2. The range of acute angle is between 45°-70°. While ensuring that the ratchet roller can better realize the cable management operation, it can also make it easier for people to hold the herringbone wrench to turn the ratchet roller.

3. The length of the handle of the figure wrench is adjustable, and the length of the handle part can be adjusted according to the position of the installer, so that it is convenient to hold the figure wrench and turn the ratchet roller. The middle of the handle is concave to increase the comfort when holding.
