A kind of long sleeve pipe self-threading device
Technical field
The present invention relates to the instrument that a kind of flexible conductor passes sleeve pipe, be specifically related to a kind of long sleeve pipe self-threading device.
Background technology
At present, when house fitting-up, generally all adopt plastic bushing to be preset within the walls or in the canopy, in sleeve pipe, penetrate lead, optical cable, telephone wire etc. then and connect up, like this, just can't see in disorder lead indoor.Be easy to when the threading for some harder leads, but it is just relatively more difficult for softer lead (as telephone wire, optical cable etc.), existing Threading tool is harder slender bodies, be fixed on the termination of this instrument with flexible conductor, the traction flexible conductor carries out threading, and threading also will be pulled out instrument after finishing, and operation is wasted time and energy, when particularly sleeve pipe is longer, use inconvenient more.
Summary of the invention
In order to overcome the deficiency that existing Threading tool operation is wasted time and energy and used inconvenience, the invention provides a kind of long sleeve pipe self-threading device, this long sleeve pipe self-threading device adopts electronic car body traction flexible conductor, has the advantages that operation is time saving and energy saving, easy to use and threading efficient is high.
Technical scheme of the present invention is: a kind of long sleeve pipe self-threading device, comprise columnar main body, guide head and wire interconnecting piece, guide head is a bullet-shaped and an end that is fixed on main body, the main body internal fixation has direct current machine, circuit board and battery, be provided with gear chamber and roller installing rack in the main body, be provided with large fluted disc in the gear chamber, reversing shaft and pass the driving shaft of gear chamber, the two ends of reversing shaft are connected with Intermediate bevel gears respectively, driving shaft is provided with the output bevel gear, the output bevel gear is meshed with Intermediate bevel gears, the two ends of driving shaft connect worm screw by spring respectively, the output shaft of direct current machine links to each other with large fluted disc, and large fluted disc is meshed with the Intermediate bevel gears of reversing shaft one end; The roller installing rack is provided with the strip gab groove, the roller assembly is installed in the open slot, roller shaft two ends in the 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 the roller assembly is positioned at groove.
Described wire interconnecting piece is provided with the snap joint that is connected with lead.
On the described wire interconnecting piece switch is installed.
Described driving shaft is at least three, and circumferentially evenly distributes along main body.
The present invention has following beneficial effect: owing to take such scheme, direct current machine rotates and drives the large fluted disc rotation, and large fluted disc flows to driving shaft by reversing shaft with power, and drive shaft turns drives worm screw and rotates, and then the roller assembly is rotated, wheel body on the roller assembly is attached to the inwall of threading sleeve pipe in use, and main body is walked along internal surface of sleeve pipe, takes flexible conductor to the other end from an end of sleeve pipe, be fit to long sleeve pipe, the threading operation is time saving and energy saving, easy to use, threading efficient height.

Embodiment
The invention will be further described below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of long sleeve pipe self-threading device, comprise columnar main body 1, guide head 2 and wire interconnecting piece 3, guide head 2 is a bullet-shaped and an end that is fixed on main body 1, main body 1 internal fixation has direct current machine 4, circuit board 5 and battery 6, be provided with gear chamber 7 and roller installing rack 8 in the main body 1, be provided with large fluted disc 9 in the gear chamber 7, reversing shaft 10 and pass the driving shaft 11 of 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 13, output bevel gear 13 is meshed with Intermediate bevel gears 12, the two ends of driving shaft 11 connect worm screw 15 by spring 14 respectively, the output shaft of direct current machine 4 links to each other with large fluted disc 9, and large fluted disc 9 is meshed with the Intermediate bevel gears 12 of reversing shaft 10 1 ends; Roller installing rack 8 is provided with strip gab groove 16, roller assembly 17 is installed in the open slot 16, roller shaft two ends in the 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 the roller assembly 17 is positioned at groove 19.Owing to take technique scheme, direct current machine 4 rotates and drives large fluted disc 9 rotations, and large fluted disc 9 flows to driving shaft 11 by reversing shaft 10 with power, and driving shaft 11 rotates drive worm screw 15 and rotates, and then roller assembly 17 is rotated, wheel body on the roller assembly 17 is attached to the inwall of threading sleeve pipe in use, and main body 1 is along internal surface of sleeve pipe walking, takes flexible conductor to the other end from an end of sleeve pipe, be fit to long sleeve pipe, the threading operation is time saving and energy saving, easy to use, threading efficient height.Because spring 14 makes between worm screw 15 and the driving shaft 11 and forms flexible connection, can adapt to the bigger sleeve pipe of internal diameter deviation, and under the not really smooth situation of inwall, the effect one of spring 14 is that to make roller assembly 17 can reach main body 1 within the specific limits outer or be withdrawn in the main body 1, has adaptability preferably, the 2nd, enough frictional force can be provided, avoid roller assembly 17 on internal surface of sleeve pipe, to skid.
Described wire interconnecting piece 3 is provided with the snap joint 20 that is connected with lead.Snap joint 20 can be connected lead apace with wire interconnecting piece 3, improve threading efficient.
On the described wire interconnecting piece 3 switch 21 is installed.Switch 21 control direct current machines 4 switch on and off power supply, in circuit board 5 receiver can be installed certainly, externally control with remote controller.
Described driving shaft 12 is at least three, and circumferentially evenly distributes along main body 1.Present embodiment variety of priority driven axle 12 is four, and worm screw 15 is 8, and roller assembly 17 is 8.
