Description
Technical field
The present invention relates to electric wire mounting technique fields, specially apparatus for fixing cord.
Background technology
Electric wire is the conducting wire for transmitting electric energy, is made of one or a few conducting wire flexible, outer bread is with light and soft
Sheath.Electric wire mostly uses Electric wire clamp during installation and use and the outer wall of electric wire is clamped, to be used for fixing its position
It sets.Existing apparatus for fixing cord is only used for the clamping of individual wires, if the required fixed electric wire of installation in some region
Quantity is more, and the consumption of electric wire setting tool can be caused excessive, causes to waste, and increases cost；And it is solid using excessive electric wire
Determine device also can cause more serious destruction to institute installation region, such as metope, ground.However, fixing dress using an electric wire
The outer wall of more electric wires can be pressed together when setting while more electric wires are clamped, it is not only inconvenient subsequently to individual wires in this way
It is separately maintained, and since the effect expanded with heat and contract with cold causes electric wire thicker or attenuates when hot weather so that electric wire is fixed
Electric wire outer wall is cut and causes to leak electricity by device, or cannot clamp electric wire, to bring the security risk that electric wire uses process.
Invention content
The invention is intended to provide apparatus for fixing cord, to solve electric wire because of the effect expanded with heat and contract with cold, results in electric wire and fix
The problem of device cuts electric wire outer wall and cannot clamp electric wire.
The present invention provides base case：Apparatus for fixing cord includes the fixing sleeve in electric wire paved surface and confession
The spiral steel bar that electric wire passes through, the fixing sleeve are equipped with clamping device and pulling force sensor, and the pulling force sensor passes through control
Device processed is connected with display；The fixing sleeve inner wall is equipped with the spiral guide slot screwed in for spiral steel bar, is set in spiral guide slot
There is the shackle member of fixed spiral steel bar one end, the shackle member is manually controllable or automatically controls, the spiral steel bar other end
It is stretched out outside fixing sleeve across clamping device.
Wherein, electric wire paved surface refers to the place being fixedly mounted needed for electric wire.
The operation principle of base case：The apparatus for fixing cord first can be positioned on electric wire paved surface, spiral steel bar by this programme
In advance by the way that in spiral guide slot precession fixing sleeve, one end that spiral steel bar enters fixing sleeve is fixed by shackle member, spiral steel bar
The other end pass through clamping device to stretch out outside fixing sleeve, more electric wires are then had passed through into spiral steel bar, unclamp clamping device, are drawn
Dynamic spiral steel bar stretches out one end of fixing sleeve, applies pressure to more electric wires, at this time display by pulling force sensor by spiral shell
It revolves and show the size of pulling force under the pulling force of steel bar, wherein detect to tense in more electric wires previously according to electric wire radical required
Then suitable pulling force adjusts pulling force size according to show value, to clamp more electric wires, which obviate damaged because pulling force is excessive
Then electric wire outer wall closes clamping device and fixes spiral steel bar.This programme can also first by fixing sleeve be positioned on electric wire paved surface, more
Electric wire passes through fixing sleeve, then screws in spiral steel bar in fixing sleeve by spiral guide slot, spiral steel bar enters fixing sleeve
One end is fixed by shackle member, then spiral steel bar is pulled to stretch out one end outside fixing sleeve, clamps more electric wires, then fill by clamping
It sets and secures spiral steel bar.
The advantageous effect of base case is：1, the present invention is clamped to more electric wires by steel bar, utilizes steel bar
Performance of expanding with heat and contract with cold is good, occurs thicker or when attenuating because expanding with heat and contract with cold in electric wire, and steel bar can be deformed upon with electric wire, to
Always more electric wires are clamped, the problem of avoiding electric wire outer wall from cutting and cause to leak electricity, or electric wire cannot be clamped.With existing electric wire
Fixing device is compared, and electric wire is greatly protected, and reduces the excessive consumption of apparatus for fixing cord.
2, it sets steel bar to helical structure, pulls spiral steel bar, effectively tighten more electric wires.When shackle member uses hand
When dynamic control, unclamping shackle member can screw out spiral steel bar from fixing sleeve, reach the dismountable effect of spiral steel bar,
Spiral steel bar is using after long, it is possible that damage, then spiral steel bar can be taken out, the spiral steel bar more renewed.
It is damaged if it is existing apparatus for fixing cord, not only needs all to replace apparatus for fixing cord, electric wire can't be fixed
However even if the present invention plays the role of fixed electric wire if taken out spiral steel bar fixing sleeve, so the present invention not only passes through spiral shell
Rotation steel bar realizes the effect for clamping electric wire, and the fixation of electric wire is also realized by fixing sleeve.
3, spiral guide slot in fixing sleeve is set, be that spiral steel bar enters in fixing sleeve for convenience, and due to spiral
Guide groove provides a screw-in path to spiral steel bar, can prevent from cutting electric wire outer wall when spiral steel bar precession, and scratch fixation
The inner wall of set.
4, shackle member is by the way of automatically controlling, by the way that spiral steel bar is screwed in fixing sleeve, spiral from spiral guide slot
Steel bar can automatic trigger shackle member be fixed, reduce process, improve work efficiency.So the present invention can be solid according to electric wire
