A kind of long sleeve pipe automatic threading apparatus
Technical field
The present invention relates to the instrument of a kind of flexible conductor through sleeve pipe, be specifically related to a kind of long sleeve pipe automatic threading apparatus.
Background technology
At present, when house fitting-up, generally all adopt plastic bushing to be preset within the walls or in canopy, in sleeve pipe, then penetrate wire, optical cable, telephone wire etc. connect up, like this, just can't see in disorder wire in indoor.Some harder wires are easy to when threading, but it is just more difficult for softer wire (as telephone wire, optical cable etc.), existing Threading tool is harder slender bodies, the termination of this instrument is fixed on flexible conductor, traction flexible conductor carries out threading, and also instrument will be pulled out after threading terminates, operation is wasted time and energy, when particularly sleeve pipe is longer, use more inconvenient.
Summary of the invention
Waste time and energy to overcome the operation of existing Threading tool and use inconvenient deficiency, the invention provides a kind of long sleeve pipe automatic threading apparatus, this long sleeve pipe automatic threading apparatus adopts electronic car body traction flexible conductor, has the advantages that operation is time saving and energy saving, easy to use and threading efficiency is high.
Technical scheme of the present invention is: a kind of long sleeve pipe automatic threading apparatus, comprise columnar main body, guide head and wire interconnecting piece, guide head is bullet-shaped and is fixed on one end of main body, main body internal fixtion has direct current machine, circuit board and battery, gear chamber and roller installing rack is provided with in main body, large fluted disc is provided with in gear chamber, reversing shaft and the driving shaft through gear chamber, the two ends of reversing shaft are connected with Intermediate bevel gears respectively, driving shaft is provided with output bevel gear wheel, output bevel gear wheel is meshed with Intermediate bevel gears, the two ends of driving shaft are respectively by spring connecting worm, the output shaft of direct current machine is connected with large fluted disc, large fluted disc is meshed with the Intermediate bevel gears of reversing shaft one end, roller installing rack is provided with strip gab groove, roller assembly is installed in open slot, roller shaft two ends in roller assembly are positioned at open slot and can slide along open slot, the centre of roller assembly is provided with the worm gear suitable with worm screw, main body wall is provided with groove along generatrix direction, and the wheel body in roller assembly is positioned at groove.
Described wire interconnecting piece is provided with the snap joint be connected with wire.
Described wire interconnecting piece is provided with switch.
Described driving shaft is at least three, and is uniformly distributed along main body circumference.
The present invention has following beneficial effect: owing to taking such scheme, direct current machine rotates and drives large fluted disc to rotate, and power is flowed to driving shaft by reversing shaft by large fluted disc, and drive shaft turns drives worm screw to rotate, and then roller assembly is rotated, wheel body in use on roller assembly is attached to the inwall of threading sleeve pipe, and main body is walked along internal surface of sleeve pipe, takes flexible conductor to the other end from one end of sleeve pipe, be applicable to longer sleeve pipe, threading operation is time saving and energy saving, easy to use, and threading efficiency is high.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, a kind of long sleeve pipe automatic threading apparatus, comprise columnar main body 1, guide head 2 and wire interconnecting piece 3, guide head 2 is bullet-shaped and is fixed on one end of main body 1, main body 1 internal fixtion has direct current machine 4, circuit board 5 and battery 6, gear chamber 7 and roller installing rack 8 is provided with in main body 1, large fluted disc 9 is provided with in gear chamber 7, reversing shaft 10 and the driving shaft 11 through gear chamber, the two ends of reversing shaft 10 are connected with Intermediate bevel gears 12 respectively, driving shaft 11 is provided with output bevel gear wheel 13, output bevel gear wheel 13 is meshed with Intermediate bevel gears 12, the two ends of driving shaft 11 are respectively by spring 14 connecting worm 15, the output shaft of direct current machine 4 is connected with large fluted disc 9, large fluted disc 9 is meshed with the Intermediate bevel gears 12 of reversing shaft 10 one end, roller installing rack 8 is provided with strip gab groove 16, roller assembly 17 is installed in open slot 16, roller shaft two ends in roller assembly 17 are positioned at open slot 16 and can slide along open slot 16, the centre of roller assembly 17 is provided with the worm gear 18 suitable with worm screw 15, main body 1 sidewall is provided with groove 19 along generatrix direction, and the wheel body in roller assembly 17 is positioned at groove 19.Owing to taking technique scheme, direct current machine 4 rotates and drives large fluted disc 9 to rotate, and power is flowed to driving shaft 11 by reversing shaft 10 by large fluted disc 9, and driving shaft 11 rotates and drives worm screw 15 to rotate, and then roller assembly 17 is rotated, wheel body in use on roller assembly 17 is attached to the inwall of threading sleeve pipe, and main body 1, along internal surface of sleeve pipe walking, takes flexible conductor to the other end from one end of sleeve pipe, be applicable to longer sleeve pipe, threading operation is time saving and energy saving, easy to use, and threading efficiency is high.Because spring 14 makes to form flexible connection between worm screw 15 and driving shaft 11, the sleeve pipe that inner diameter deviation is larger can be adapted to, and inwall not bery smooth when, the effect one of spring 14 makes roller assembly 17 can reach outside main body 1 within the specific limits or be retracted in main body 1, there is good adaptability, two is to provide enough frictional force, avoids roller assembly 17 to skid on internal surface of sleeve pipe.
Described wire interconnecting piece 3 is provided with the snap joint 20 be connected with wire.Wire can be connected with wire interconnecting piece 3 by snap joint 20 rapidly, improves threading efficiency.
Described wire interconnecting piece 3 is provided with switch 21.Switch 21 controls direct current machine 4 and switches on and off power supply, and certainly can install receiver in circuit board 5, in outside, remote controller controls.
Described driving shaft 11 is at least three, and is uniformly distributed along main body 1 circumference.The present embodiment variety of priority driven axle 11 is four, and worm screw 15 is 8, and roller assembly 17 is 8.
