Paying-off device

Abstract

The invention discloses a paying-off device which comprises a bracket and a runner, wherein the runner is fixed in the middle of the bracket; the runner comprises a fixed baffle, a lead screw, a sleeve shaft, an expansion bracket and a movable baffle; a handle is arranged at the outside axis of the fixed baffle; the lead screw is arranged at the inside axis of the fixed baffle; the handle penetrates through the fixed baffle and is fixedly connected with one end of the lead screw; the outside of the lead screw is annularly sleeved with a sleeve shaft, and three longitudinal long slotted holes are uniformly formed in the sleeve shaft; the expansion bracket comprises a first lantern ring, a second lantern ring and three expansion supports with the same structure; each expansion support comprises an arc plate, a first supporting rod and a second supporting rod; the lead screw is provided with a first nut and a second nut; the outside of the sleeve shaft is annularly sleeved with the lantern rings; the lantern rings are fixedly connected with the nuts through screws; the screws can slide along the long slotted holes in the sleeve shaft. According to the paying-off device, the structure is simple, the manufacturing cost is low, portability is realized, the diameter of each expansion bracket can be adjusted according to the inner diameter of different wire discs, and the operation is convenient.

Description

technical field [0001] The invention relates to a wire pay-off and belongs to the technical field of electric construction tools. Background technique [0002] In the process of electric power construction or electrical appliance installation, a large number of wires, cables, etc. are usually used, and usually the wires, cables, etc. are packaged in rolls, and the wires need to be released during installation. The traditional unwinding work is that the operator strings up the coiled wires with his hands and then releases them. It often requires two people to cooperate, which is time-consuming and laborious; , Scattered, seriously affecting work efficiency and construction quality. [0003] Common pay-offs on the market have complex structures and single functions, and cannot adjust the diameter of the rotating shaft according to different inner diameters of wire reels. Contents of the invention [0004] The technical problem to be solved by the present invention is to pr...
