Abstract
Description
[Technical Field]
[0001] The present invention relates to the technical field of cable concentrators, and more particularly to a cable concentrator that can be used in a lying position without relying on a lift handle. [Background technology]
[0002] Referring to FIG. 1, a conventional manual cable concentrator 1 is made of plastic and includes a take-up wheel 10 and a lift handle 11 connected above the take-up wheel 10. When operating the manual cable concentrator 1 on a flat surface, the operator holds the lift handle 11 with one hand while supporting the weight of the pull cable 100, and rotates the take-up wheel 10 with the other hand, causing the pull cable 100 wound around the inside of the take-up wheel 10 to rotate together with the handle, thereby letting out or retracting the pull cable 100 inside the take-up wheel 10. This operation requires a great deal of effort and is inconvenient. However, when operating the manual cable concentrator 1 at a high altitude, the operation of holding the handle 11 with both hands while supporting the weight of the pull cable 100 is extremely dangerous.
[0003] 2 , a conventional electric cable concentrator 2 uses a handle 20 to move a pull cable 210 inside a take-up wheel 21. The handle 20 includes a metal body 201, a pressure member 202 made of a plastic material and pinned to one upper end of the handle 20, and an engagement member 203 pinned to the middle of the handle 20. A pulley 204 is provided inside one end of the handle 20, and a shaft 205 protrudes from one side of the pulley 204, to which an electric drill tool 22 is attached. When operating the electric cable concentrator 2 on a flat surface, the operator holds the handle 20 with one hand to support the weight of the pull cable 210, and holds the electric drill tool 22 with the other hand to rotate the take-up wheel 10 instead of the manual cable concentrator 1 to feed or retract the pull cable 210 inside the take-up wheel 21. However, because the electric cable concentrator 2 still requires both hands to be used, the operation is laborious and inconvenient. However, when operating the electric line concentrator 2 at a high place, the operation of holding and rotating the electric drill tool 22 while also bearing the weight of the pull cable 210 with both hands is even more dangerous.
[0004] 3, a ground-mounted concentrator 3 is designed, which includes a metal support 30, a take-up wheel 31 pin-connected to one side of the metal support 30 by an axis 311, a support rod 32 connected to the upper part of the opposite side of the metal support 30, and a spring tube 33 fixed to one end of the support rod 32. The spring tube 33 rotates the pull cable 312 in the take-up wheel 31 to feed or retract it. Because the concentrator 3 is operated on the ground, the metal support 30 needs to be designed to be large and heavy so that it does not tip over when feeding out the pull cable 312 in the take-up wheel 31. However, this heavy weight makes it inconvenient to carry the concentrator 3. However, when operating the concentrator 3 at a high altitude, if the length of the spring tube 33 is insufficient, one person will have to pay out the wire at a high altitude and another person will have to retrieve the wire on the ground while holding the spring tube 33, making it impossible to pull back the pull cable 312 inside the winding wheel 31, and improvement is required. Summary of the Invention [Problem to be solved by the invention]

[0018] The technical contents of the present invention will be described in detail below with reference to the drawings. 4 to 6, 7 and 8, the present invention provides a wire concentrator 4 including a winding wheel 5, a roller 6, a fixed frame 7 and a spring tube 8. When using the wire concentrator 4, an operator can immediately pay out or smoothly retrieve a wire without relying on a lift handle and while the wire concentrator 4 is lying on the ground at the work site.
[0019] Winding wheel 5 includes first hemispherical frame 50 and second hemispherical frame 51 assembled to first hemispherical frame 50, with winding area 52 for storing pull cable 9 provided inside winding wheel 5. Convex frame body 501 is connected to the center of the side surface of first hemispherical frame 50, with housing 502 provided in convex frame body 501 and an annular convex body 503 on the inner edge. First hemispherical frame 500 is provided with a plurality of first convex claws 504 on the outer edge, with these first convex claws 504 spaced apart, and a wire fixing port 505 for fixing one end 91 of pull cable 9 to prevent it from falling off is provided below one of first convex claws 504.
[0020] In the winding wheel 5, a passage 511 for the protruding frame body 501 is provided at the center of the second hemispherical frame 51, and the outer edge of the second hemispherical frame 51 has a plurality of second protruding claws 512 provided at intervals, and these second protruding claws 512 are assembled to correspond to these first protruding claws 504 of the first hemispherical frame 50. However, these first protruding claws 504 may also be assembled by butting against these second protruding claws 512 by screwing, crimping, fitting, or the like.
[0021] The roller 6 is located within the receiving section 502, allowing the roller 6 to rotate freely relative to the winding wheel 5. The roller 6 includes a base 61 and a plurality of roll wheels 62, the base 61 being located within the receiving section 502, and the roll wheels 62 being located on the outer edge of the base 61. In this embodiment, both sides of the base 61 are each provided with a limiting section 611 recessed inward, and the outer edge of the base 61, located between the two limiting sections 611, is provided with a plurality of spaced-apart shaft holes 612. Each of these roll wheels 62 includes a male mating wheel 621 and a female mating wheel 622, and each male mating wheel 621 has a square protruding post 6211, which is fitted into a corresponding square insertion hole 6221 having an axle 6220 of each female mating wheel 622. After fitting, each axle 6220 of each female mating wheel 622 is positioned in each axle hole 612 and rotates, so that each male mating wheel 621 and each female mating wheel 622 is located in each of the two limiting portions 611 and rotates relative to the annular protruding body 503 on the inner edge of the convex frame body 501.
[0022] One side of the fixed frame 7 is fixed to one side of the roller 6 to lay the take-up wheel 5. The fixed frame 7 includes a bottom plate 71 and a support frame 72. The four corners of the bottom plate 71 are each provided with through-holes 711 for fitting pads 712. These pads 712 on the bottom plate 71 stably lay the bottom plate 71 without sliding. A fixing protrusion 713 protrudes from the bottom plate 71 toward the bottom of the first hemispherical frame 50, and one side of the fixing protrusion 713 is fixed to one side of the base 61. This forms a gap 714 between the fixing protrusion 713 and the bottom of the first hemispherical frame 50, allowing the take-up wheel 5 to continue rotating stably. However, the fixing protrusion 713 may also be attached to the base 61 by screwing, crimping, fitting, or other methods.
[0023] The support frame 72 includes a side plate frame 73 and a support 74. One side of the side plate frame 73 is fixed to the opposing side of the base 61, and the support 74 is fixed on the side plate frame 73. In this embodiment, the side plate frame 73 is roughly rectangular, and the center of the opposing side of the side plate frame 73 has a recessed surface 731. However, the side plate frame 73 may also be attached to the base 61 by screwing, caulking, fitting, or the like.
[0024] Furthermore, the support 74 includes a cover 741 fixed to the recessed surface 731, a standing plate 742 connected to the cover 741, and a conduit 743 connected to the upper part of the standing plate 742, the cover 741 including two rectangular fittings 7411, and the conduit 743 being obliquely provided with a drilled hole 7431. However, the support 74 may also be assembled to the side plate frame 73 by fitting. In this embodiment, the recessed surface 731 of the side plate frame 73 has two square fitting grooves 732 corresponding to the two square fitting bodies 7411 of the cover body 741. As a result, when the cover body 741 of the support 74 is fixed to the recessed surface 731 of the side plate frame 73, the two square fitting bodies 7411 fit into and fix the cover body 741 to the two square fitting grooves 732, and the cover body 741 and the side plate frame 73 are further screwed together, thereby strengthening the fixation of the cover body 741 to the side plate frame 73.
[0025] Referring to Figures 4 to 6, one end 81 of the spring tube 8 is inserted obliquely into the wire winding region 52 through the drilled hole 7431, and the other end 82 of the spring tube 8 is pulled out obliquely along the drilled hole 7431, thereby leading out the other end 92 of the pull cable 9.
[0026] 4 and 9, in one embodiment, the conduit 743 further includes a first retaining ring 744 and a second retaining ring 745 assembled to the first retaining ring 744, the first retaining ring 744 being hollow and having one end 7441 inserted into the drilled hole 7431, and the second retaining ring 745 being fitted onto the one end 7441 of the first retaining ring 744, such that the one end 81 of the spring tube 8 is inserted into the wire-winding region 52 by the first retaining ring 744. The other end 82 of the spring tube 8 is formed with an expanded tube portion, and the outlet end of the expanded tube portion is provided with an internal thread.
[0027] Optionally, in one embodiment, as shown in Figures 10 and 11, the line concentrator 4 further includes at least one extension spring tube 8a, which is connected to the expanded portion at the other end 82 of the spring tube 8. One end of the extension spring tube 8a has an external thread that mates with and is screwed onto the internal thread of the expanded portion, and the other end of the extension spring tube 8a has an expanded portion, the outlet end of which has an internal thread, allowing multiple extension spring tubes 8a to be screwed together and allowing the operator to add more extension spring tubes 8a depending on the height and location of the work area.
[0028] 4 to 8, 9, and 12, in this embodiment, one end 91 of the pull cable 9 is fixed to the wire fixing port 505 and stored in the wire winding area 52, and the other end 92 of the pull cable 9 is led out from the other end 82 of the spring tube 8 or the other end 82a of the extension spring tube 8a as shown in FIGS. 10 and 11. During operation, an operator holds the other end 82 of the spring tube 8 or the other end 82a of the extension spring tube 8a with one hand, and holds the other end 92 of the pull cable 9 with the other hand and pulls it in or feeds it out as shown in FIG. 13, whereby the wire concentrator 4 is rotated in a roller 6, the winding wheel 5 and the protruding frame 501 are rotated clockwise or counterclockwise as shown in FIG. 13, so that the other end 92 of the pull cable 9 in the wire winding area 52 is fed out from the other end 82 of the spring tube 8 or the other end 82a of the extension spring tube 8a by rotating clockwise, or is pulled back into the wire winding area 52 by rotating counterclockwise as shown in FIG. 13. This allows the operator to immediately pay out or smoothly retrieve the wire without relying on a lift handle and while the device is lying on the ground at the work site, which is very convenient to use, saves effort, and allows for quick operation.
