Description

[Technical Field]

[0001] The present invention relates to the technical field of handles, and more particularly to a cable puller handle for smooth and stable transport of a pull cable inside a cable winding and discharging device. [Background technology]

[0002] 1 and 2, currently, when installing electric wires inside a new room or an old house, an exposed electric wire path is made into a culvert, and a cable puller handle 1 is used inside the culvert to move a pull cable 100 inside a cable winding and discharging device 10. The cable puller handle 1 includes a metal handle body 11, a pressure member 12 made of a plastic material and pin-connected to one upper end of the cable puller handle 1, and an engagement member 13 pin-connected to an intermediate position of the cable puller handle 1. A pulley 110 is provided inside one end of the handle body 11, and a rotating shaft 111 protrudes from the pulley 110, and an output end of an external power source is attached to the rotating shaft 111. A plurality of grooves 121 are arranged at intervals on the outer periphery of the front end of the pressing body 12 to fit the engaging body 13, and the engaging body 13 is adjusted to move toward one of these grooves 121 until it can press and restrict the pull cable 100 according to different wire diameters (thicknesses) of the pull cable 100.

[0003] 1 and 2, investigations have revealed that pull cable 100 has a rough surface 101, and that pressing body 12 is pressed against rough surface 101 against which pull cable 100 is pulled. The inner surface 122 of pressing body 12 is hardened by rough surface 101 against which pull cable 100 is pulled, resulting in high frictional resistance, which easily forms wear depressions 123 and causes wear on pull cable 100 and cable puller handle 1. As cable puller handle 1 is used, wear depressions 123 deepen, and when wear depressions 123 become too deep and the resistance of pressing body 12 against pull cable 100 becomes too low to be usable, it is necessary to readjust engaging body 13 so that it moves to the bottom of groove 121 to increase resistance in order to continue using the handle (see FIGS. 3 and 4).

[0004] Furthermore, groove 121 provided in pressing body 12 is not only limited by different wire diameters (thicknesses) of pull cables 100, but also must constantly adjust to the movement of engaging body 13. In other words, with conventional cable puller handles 1, it is not possible to adjust the resistance to be optimal for pull cables 100 of different wire diameters (thicknesses), and pressing body 12 either presses on pull cable 100 too much, causing greater wear as a result of pressing down on pull cable 100, or is too loose, making it difficult to pull pull cable 100 or allow it to follow movement smoothly.

[0005] 1 to 4, the handle body 11 of the cable puller handle 1 is made of metal, has little shape change, and is heavy, making it difficult for electricians to pick it up at the work site and undesirable for use. There is still room for improvement in the overall structure of the cable puller handle 1. Summary of the Invention [Problem to be solved by the invention]

The cover part 51 has recessed edges 513 formed near the two sides of the axle contact body 512, and the two recessed edges 513 are used to move the press wheels 53 of the two right convex arms 522 rightward and insert them therein. The axle contact body 512 has holes 5121 formed therein corresponding to the shaft holes 451 of the axle contact bodies 45. The shaft 5122 is inserted into the shaft holes 451 and holes 5121 of each of the protrusions 45, so that the shaft contact 512 forms a pin joint with each of the protrusions 45. The shaft contact 512 has a recessed arc opening 5123 at the front end of each of the protrusions 45, and the depth of the recessed arc opening 5123 is greater than the depth of each of the annular recessed arc grooves 5311 of each roller 531 (see FIG. 10). The recessed arc opening 5123 and each of the annular recessed arc grooves 5311 are used to feed or pull back the pull cable 8 toward the first guide wheel 61 or the second guide wheel 62 (see FIGS. 11A and 11B).

[0033] In one embodiment, the grip 3 is made of a plastic material with the two press wheels 53 protected inside, which allows the grip 3 to be shaped in a variety of ways and is ergonomic, allowing electricians to hold the grip 3 with their hands at the work site, which is very convenient for use. Also, because the two press wheels 53 are made of metal, the pull cable 8 is pulled smoothly and is not hard abraded by the rough surface of the pull cable 8 during pulling.

[0034] 7, 8, and 12 to 14, a connection frame 71 is provided above the cable winding and discharging device 7, and the connection frame 71 includes protruding fitting portions 72 located on the two upper side edges of the connection frame 71 and fitted to correspond to each slide rail 471 of each fitting portion 47, and channels 73 located below both sides of the protruding fitting portions 72 and fitted to correspond to each fitting portion 47. However, recessed edges 721 that engage with each stopper 472 are provided at the bottom ends on both sides of the protruding fitting portions 72, and each stopper 472 of the cable puller handle 2 is received by one of the recessed edges 721 on the connection frame 71, preventing the cable puller handle 2 and the connection frame 71 from falling off. By fitting each fitting portion 47 of the cable puller handle 2 into the connection frame 71 of the cable winding and discharging device 7, the cable puller handle 2 is assembled to the cable winding and discharging device 7 for use. An electrician can install the cable puller handle 2 above the cable winding and discharging device 7 to work and use the rotating set 70 provided inside the cable winding and discharging device 7 to move the pull cable 8 to feed or pull back, which is very convenient for use.

[0035] Also, referring to Figure 15, in another embodiment of the cable winding and discharging device 7a of the present invention, a frame 71a is formed in the cable winding and discharging device 7a, and the frame 71a transports the pull cable 8 to be let out or pulled back by a rotating shaft set 72a.

[0036] 5 to 11B and 14, before pulling and transporting the pull cable 8, the electrician first loosens the manual knob 333 of the adjustment part 33, moves the adjustment part 33 within the two adjustment grooves 313, and changes its position, thereby moving the cover part 51 upward into the accommodation space 311 of the outer fixing frame 31 toward one end of the shaft contact 512, and then moves the press wheels 53 of the two right convex arms 522 rightward and into the two concave edges 513 of the shaft contact 512, thereby adjusting the distance H between the bottom of each annular concave arc groove 5311 of each roller 531 and the pulley 63. 10), and then pull the pull cable 8 inside the spiral tube 48 installed at the end of the base 4, passing it through the circular concave arc grooves 5311 of the rollers 531 and under the concave arc openings 5123 of the axle bearing body 512 (see FIG. 9A). When the adjustment part 33 moves downward within the two adjustment grooves 313 according to the different wire diameters (thicknesses) of the pull cable 8, as shown in FIG. 9B, the press wheels 53 of the two left convex arms 522 first contact the pull cable 8, and then the internal threads 3331 of the hand knob 333 and the external threads 3311 of the first bolt 331 face each other. As the rollers 531 move and are screwed, the first sleeve 332 of the adjustment part 33 is pushed to abut against one end of the cover part 51 at an upper position, and the press wheels 53 of the two left convex arms 522 further rotate toward the inside of the receiving space 311. At the same time, the press wheels 53 of the two right convex arms 522, which are inserted into the two concave edges 513 of the axle contact body 512, rotate toward the pull cable 8 (see FIG. 9C). The distance H between each annular concave arc groove 5311 of each roller 531 and the pulley 63 becomes equal to the distance H between the pull cable 8 and each press wheel 53. When the pull cable 8 is to be advanced or retracted toward the first guide wheel 61 or the second guide wheel 62 (see FIGS. 8 and 11A), the output end of the external power 9 is attached to the long shaft 614 and the forward or reverse direction is set as shown in FIG. 11B. When the long shaft 614 rotates forward or reverse relative to the drive gear 611, the drive gear 611 rotates forward or reverse relative to the pulley 63, and the pull cable 8 between the two press wheels 53 and the pulley 63 rotates forward or reverse relative to the pulley 63.The driven gear 621 rotates forward or backward following the driving gear 611, transporting the pull cable 8 of the cable winding and discharge device 7 or the cable winding and discharge device 7a of FIG. 15 to a culvert installed inside the new room or the old house, winding the electric wire around the pulling head 80 at one end of the pull cable 8 of the cable winding and discharge device 7 or the cable winding and discharge device 7a of FIG. 15, or transporting the electric wire wound around the pulling head 80 at one end of the pull cable 8 of the cable winding and discharge device 7 or the cable winding and discharge device 7a of FIG. 15 back to a culvert installed inside the new room or the old house, thereby allowing the electrician to quickly and smoothly perform pulling at the work site and work stably and quickly.
