Description

Folding portable pay-off rack

Technical Field

The utility model relates to the field of paying-off tools, in particular to a folding portable pay-off rack.

Background

When in electric engineering construction, strong-current systems (power and illumination) and weak-current systems (telecommunication, television, alarm and intelligent) all need to be threaded in a pipe, and the systems are composed of single-strand or multi-strand wires and insulating layers and are used for connecting circuits, electric appliances and the like. A traditional wire pay-off rack adopts a steel bar to weld a cross base, a fixed bearing is additionally arranged in the middle of a vertical rod to rotate, and an electric coil is loosened by rotating the middle bearing. The following disadvantages exist with this approach: inconvenient movement, low turnover rate and wire winding phenomenon sometimes occur. Because constructors pull the speed unevenly, the electric wire can generate certain torsion, so that the electric wire is twisted together, and then the constructors are required to turn over the electric wire to untangling the coil, thereby not only affecting the construction efficiency, but also being inconvenient in operation.

Therefore, how to create a new folding portable pay-off rack is one of the important research and development problems at present.

Detailed Description

Referring to fig. 1, the present utility model provides a foldable handheld pay-off rack, which includes a front frame 1, a rear frame 2, a reinforcing support plate 4, a rotating shaft 5 and a turntable 6.

The front frame 1 and the rear frame 2 are rectangular frame structures, the tops of the front frame 1 and the rear frame 2 are hinged through hinges 3, and a reinforcing support plate 4 is arranged between side frames of the front frame 1 and the rear frame 2. The end part of one end of the reinforcing support plate 4 is rotationally connected with the side frame of the rear frame 2, the end part of the other end of the reinforcing support plate is provided with a clamping groove, the side frame of the front frame 1 is provided with clamping nails, and when the front frame 1 and the rear frame 2 are in an unfolding state, the reinforcing support plate 4 is rotated to enable the clamping groove to be clamped on the clamping nails.

When the rotary table is used, the front frame 1 and the rear frame 2 can be unfolded for a certain angle, and the clamping grooves of the reinforcing support plates 4 are clamped on the clamping nails of the front frame 1, so that the front frame 1, the rear frame 2 and the reinforcing support plates 4 are in a triangular structure, and stable support is provided for the rotary shaft 5 and the rotary table 6. When not in use, the clamping grooves of the reinforcing support plates 4 can be separated from the clamping nails, and the front frame 1 and the rear frame 2 are folded, so that occupied space is reduced.
