Description

Technical Field

[0001] The utility model relates to the field of cable brackets, in particular to a cable support bracket for a multi-strand electric wire group. Background Art

[0002] As is known to all, when laying electric wires, multiple strands of electric wires are usually encountered, so multiple strands of electric wires are laid on a cable support frame. For example, the prior art CN217984338U discloses a rotatable temporary electric wire support frame, including a tripod, a support rod, a tow rod, a cable bracket and a movable structure for controlling the rotation of the cable bracket; this technology overcomes the inherent defects of existing temporary electric wire brackets at construction sites when laying multiple strands of electric wires, such as occupying a lot of space, high cost, and easy to cause on-site construction safety accidents, and can realize the mutual conversion between laying single strands of electric wires and multiple strands of electric wires.

[0003] However, in the conventional cable support frame, the spacing between each strand of a multi-strand wire group is relatively fixed, so it is difficult to adjust the spacing between each strand of wire according to actual needs during the actual cable installation process. If some cables are too close, insulation thermal breakdown is likely to occur, causing short circuit tripping of the wires, which may seriously cause fire safety accidents. Therefore, it is necessary to provide a cable support frame for a multi-strand wire group that can adjust the spacing between each strand of wire according to actual needs. Utility Model Content

[0008] A transversely arranged fixed screw is also fixedly installed in the transverse sliding groove, and a rotating hole is provided on the sliding seat. A threaded tube is rotatably installed in the rotating hole through a first bearing, and the right end of the threaded tube extends to the right outer side of the sliding seat and is fixedly sleeved with a worm gear. A worm is rotatably installed at the right end of the bottom of the upper sliding connecting plate, and the worm is meshed with the worm gear. The bottom end of the worm also rotates and passes through the bottom of the lower sliding connecting plate and is fixedly connected with a rotating head.

[0009] Preferably, a screw hole is provided at the bottom end of the rotating head, and the screw hole is specifically a cross screw hole.

[0010] Preferably, the top of the lower sliding connection plate is in sliding contact with the bottom side of the cable support stretcher body; the bottom of the upper sliding connection plate is in sliding contact with the top of the cable support stretcher body.

[0011] Preferably, a bearing seat is fixedly mounted on the right end of the bottom of the upper sliding connecting plate, and the top end of the worm is rotatably mounted on the bearing seat.

[0013] Preferably, the bottom ends of the two L-shaped support frames are also provided with mounting connection holes.

[0014] By adopting the above structure, the utility model has the following beneficial effects:

[0015] 1) In the utility model, it is convenient to tie and fix multiple cables on each butterfly-shaped insulating porcelain bottle above the main body of the cable support stretcher, thereby realizing the limited support of the wires and cables;

[0016] 2) In the utility model, the cooperation of the rotating head, the worm, the worm wheel, the threaded tube, the slide seat, the first bearing and the fixed screw can make the slide seat perform left or right thread transmission on the fixed screw through the threaded tube, and when the slide seat moves, it drives the upper sliding connecting plate and the wires and cables on the butterfly-type insulating porcelain bottle to adjust left or right, so that the spacing between each strand of wires and cables can be adjusted;

[0017] To sum up, the cable support frame of the multi-strand electric wire group is not only convenient for tying and fixing the multi-strand cables on the various butterfly-type insulating porcelain bottles above the cable support stretcher body, but also in the process of laying the cables, the spacing between the strands of electric wires can be adjusted according to actual needs, thereby avoiding the electric wires and cables being too close to each other and easily causing insulation thermal breakdown, resulting in accidents such as short circuits and tripping of the electric wires, and the structure is simple and easy to adjust and use.
