Description

Shearing method for network cable wiring

Technical Field

The invention relates to a shearing technology of network cable wiring, in particular to a shearing method of network cable wiring.

Background

The network cable is a common component for linking local area networks, and the common network cable includes twisted pair cables, coaxial cables and optical cables, and the twisted pair cables are widely used in offices and homes due to their low price. When the computer network is applied to office places, because the office places use more computers of the network, each computer is connected with one network cable, the use amount of the network cable is larger, and the workload of network cable wiring is larger.

At present, the net twine generally is placed in the carton to conveniently carry the net twine, when the wiring, draws out the net twine from the outlet on the carton and lays wire, when the net twine was drawn out to the fixed length, the wiring personnel need bend over and use pliers to cut off the net twine from the outlet, it is very inconvenient to use, delays the wiring progress, if do not want to bend over and cut off the net twine, the wiring personnel often can draw out a section net twine after, cut off the net twine that forms the fixed length by experience, let the net twine too short and can't link computer and network interface like this easily.

Disclosure of Invention

The invention aims to provide a cutting method for network cable wiring, which is used for directly cutting a network cable at a box body after the network cable with a fixed length is pulled out.

The shearing method for the network cable wiring in the scheme comprises the following steps:

s1, when the network cable is wired, the network cable in the box body is pulled out from the outlet of the right side wall by a preset length, and the pulled network cable is clamped by a clamping collet in the box body;

s2, pulling the net wire to press out the blunt knife in the second channel below the wire outlet downwards, making the blunt knife move downwards in the second channel, the blunt knife pressing the second pressure spring in the second channel, simultaneously, the poking block on the blunt knife poking the poking column downwards, removing the force of the poking column stretching the pull rope between the blunt knife and the cutter in the first channel above the wire outlet, making the pull rope loose, making the cutter move downwards under the action of gravity, and cutting off the net wire in the wire outlet;

and S3, after the cutting of the net wire is finished, the blunt knife is removed under the pressure of the net wire, the blunt knife resets under the action of the second pressure spring, the force of the shifting block for shifting the shifting post is removed, the shifting post automatically resets and tightens the pull rope again, and the cutter is pulled into the first channel when the pull rope is tightened.

The beneficial effect of this scheme is: when the wiring, need not to carry and use other instruments to cut the net twine, only need pull the net twine and push down and can cut off the net twine, it is more simple and convenient to use, and the net twine is straightened through stroking out of the tight section of thick bamboo of front end clamp moreover, can make the incision of net twine more level and smooth.

Further, in the step S2, the dialing block dialing the dialing pole includes the following sub-steps:

s21, the poking block pushes the second subsection of the poking column downwards to make the first subsection swing upwards, the first subsection releases the force of the pull rope, when the poking column is poked, the torsion bar is driven to rotate and the torsion spring is twisted;

s22, when the force of the shifting block is removed, the torsion spring drives the torsion bar to reset, and the torsion bar drives the shifting post to reset to tighten the pull rope again.

The cutting of the net twine is carried out only by pulling the net twine, and after the cutting is completed, the cutter does not need to be manually reset, so that the use is more convenient.

Further, the step S1 includes the following substeps when pulling out the cable:

s11, the mesh wire drives the rotating shaft in the box body to rotate, and the steel sheet in the winding strip box stores elastic potential energy when the rotating shaft rotates;

s12, when the drawn-out net wire is put back to the box body again, the steel piece releases the elastic potential energy to drive the rotating shaft to rotate and rewind the net wire.

When the net wires are pulled out more after wiring is finished, the force for pulling the net wires is released, the steel sheets release elastic potential energy to drive the rotating shaft to rotate so as to wind the net wires, the net wires are orderly rolled into the box body again, and the net wires are prevented from being placed in a mess and bent to be damaged after being rolled into the box body again.

Further, in step S1, the clamping the collet to clamp the net wire includes the following sub-steps:

s13, when the net wire is pulled out, the net wire presses the rolling balls into the grooves on the inner wall of the clamping cylinder, the space among the rolling balls in the clamping cylinder is enlarged, and meanwhile, the rolling balls press the first pressure spring into the vertical groove at the bottom of the groove;

s14, when the net twine stops to be pulled, the rolling ball is stressed and is not pressed, the first pressure spring pushes the rolling ball out of the groove, and the rolling ball clamps the net twine.

When the net wires are pulled out, the net wires can be pulled out through the pressing of the rolling balls on the inner wall of the clamping cylinder, the clamping cylinder can smooth out the straight net wires to facilitate wiring, meanwhile, part of the net wires can be pulled out, the net wires press the rolling balls to enable the clamping cylinder to have gaps, then the force for pulling the net wires is released, the rolling balls do not press the net wires at the moment of releasing the net wires, the net wires are not clamped by the rolling balls and pull the rotating shaft, the steel sheet releases elastic potential energy to drive the rotating shaft to rotate to wind the net wires, the action of pulling the net wires in a small amount is repeatedly operated until the rotating shaft completely winds the pulled redundant net wires, the processes of clamping the net wires and releasing the net wires are automatically completed when the net wires are pulled, and the use is simpler and more convenient.

Further, in step S1, the rotating shaft rotates to make the wiping rod on the outer sidewall rub against the outer wall of the clamping cylinder, so as to raise the temperature of the clamping cylinder to soften the mesh wire.

When the right angle environment at the corner was laid wire, the temperature rise of a clamping section of thick bamboo can soften the net twine, avoids the net twine to buckle when the weather is cold harder and causes the damage.

Further, step S0 is included, before the network cable is wired, when the cable is used in high temperature environment, the screw head outside the clamping cylinder is screwed to make the convex head locate in the gap between the concave grooves, when the cable is used in low temperature environment, the screw head is screwed to make the convex head protrude to directly contact with the network cable.

The raised head is positioned in the gap of the groove, so that the friction between the raised head and the net wire can be reduced while the net wire is prevented from being clamped into the gap, and the heat generated by the friction of the net wire when the raised head extends out of the gap is reduced; the raised head protrudes to be in direct contact with the net wire, so that heat generated by friction between the net wire and the raised head is increased, the straight net wire is softened and smoothed in a cold environment, and the net wire is prevented from being bent to be damaged when being hard.
