2results about How to "Simple winding structure" patented technology

This utility model provides a rapid circuit fault detection device, relating to the field of electronic engineering testing technology. It includes: a main body of the detector, with a first connecting wire at the rear; a mounting box at the bottom of the main body, through which the first connecting wire passes; a winding roller inside the mounting box, with the first connecting wire wound around it; and a rotating rod rotatably mounted inside the mounting box. The rotating rod is driven to rotate by manually turning a handwheel, and through the meshing of a worm gear and worm wheel, the winding roller can rotate around the rotating shaft, winding the first connecting wire into the mounting box. This effectively prevents the wire from becoming tangled and piled up, facilitating the carrying and use of the device. Its winding structure is simple and easy to operate, solving the problem that existing circuit fault detection devices, due to their long connecting wires, easily become tangled and piled up, causing inconvenience in carrying and using.

The utility model belongs to the technical field of batteries, and particularly relates to a battery cell, a battery and electric equipment, the battery cell comprises a first pole piece, a second pole piece and a diaphragm arranged between the first pole piece and the second pole piece, along the winding direction of the battery cell, the first pole piece comprises a plurality of first straight parts and first bent parts which are alternately arranged, and the second pole piece comprises a plurality of second straight parts and a plurality of second bent parts which are alternately arranged; the first pole piece comprises a plurality of first straight parts and a plurality of second bent parts which are alternately arranged, the second pole piece comprises a plurality of second straight parts and a plurality of second bent parts which are alternately arranged, insulating parts are arranged on the first bent parts and / or the second bent parts, the orientations of the first straight parts and the second straight parts are opposite in the innermost ring of the battery cell, and the orientations of the first straight parts and the second straight parts are opposite in the thickness direction of the battery cell. The first straight parts and the second straight parts are alternately arranged; after the battery cell is wound, the first straight parts and the second straight parts can be arranged in a one-to-one correspondence manner, and the first bent parts and the second bent parts can be arranged in a one-to-one correspondence manner, so that the thickness of the battery cell is reduced, and the waste of raw materials is reduced.
