Winder
A cord reel and cord reel technology, which is applied to current collectors, rotary current collectors, devices that can bend lead wires, etc. The friction with the intermediate shaft increases, which affects the winding and pay-off efficiency of the reel, and achieves the effects of strong wear resistance and compression resistance, reducing friction and improving efficiency.

Problems solved by technology
The existing intermediate shaft is usually made of insulating plastic. Before the reel is assembled, although the surface of the intermediate shaft is polished, in actual application, the friction between the reel and the intermediate shaft will still cause the surface of the intermediate shaft to produce The burrs cause the friction between the reel and the intermediate shaft to increase, which affects the winding and unwinding efficiency of the reel, and, because the intermediate shaft made of plastic has poor wear resistance, it will be damaged after a period of use. , the mutual wear between the reel and the intermediate shaft is too heavy and the reel cannot be used normally

Embodiment Construction
[0012] See attached figure 1 - As shown in accompanying drawing 2, a cord reel includes a connecting plate 6, an intermediate shaft 2 fixedly connected to the connecting plate 6, and a reel 9 pivotally connected to the intermediate shaft 2 , The spool 9 is formed by connecting the upper cover 7 of the spool and the lower cover 8 of the spool. The intermediate shaft 2 is a metal shaft with a smooth surface, and in a preferred embodiment commonly used in the present invention, the intermediate shaft 2 is a copper shaft. The intermediate shaft 2 made of copper metal has a smooth surface after being polished, and is durable, which helps to reduce the frictional force generated when the bobbin 9 and the intermediate shaft 2 rotate relative to each other.
[0013] See attached picture 2-attached image 3 As shown, the conductive copper sheet 3 is fixedly arranged on the connecting plate, the movable contact piece 12 is arranged on the described wire reel 9, and the described movab...

The invention discloses a coil winder, which consists of connecting board and coiling reel through rotary connection of middle shaft and connecting board, wherein the conductive copper piece is set on the connecting board; the movable contact spring is set on the coiling reel, which touches the conductive copper piece glidingly; the middle shaft is smooth surface metal shaft; the center part of connecting board projects towards coiling reel and cases the upper end of middle shaft to butt the projected part. The coiling reel is applied to wind the power wire, which reduces the abrasion degree of middle shaft effectively.
Description
technical field [0001] The invention relates to a cord reel for winding and accommodating a power cord, which is usually applied to household appliances such as vacuum cleaners and garment steamers. Background technique [0002] In the prior art, the wire reel includes a housing and a reel arranged in the housing, the housing includes a connecting plate, an intermediate shaft is fixedly connected to the connecting plate, the reel is rotatably arranged on the intermediate shaft, and the connecting plate A conductive copper sheet is arranged on the top, and the input power line and the output power line are electrically connected through the conductive copper sheet. line operation. The existing intermediate shaft is usually made of insulating plastic. Before the reel is assembled, although the surface of the intermediate shaft is polished, in actual application, the friction between the reel and the intermediate shaft will still cause the surface of the intermediate shaft to ...
