Detailed Description

As shown in fig. 1 and 4, the present invention relates to a wire winding mechanism with changeable outer diameter, which comprises a spool (not shown), an inner disc 2, an outer disc 3 and a wire winding seat 4.

The wire winding seat 4 is arranged between the inner disc 2 and the outer disc 3, and the center of the inner disc 2 is fixedly sleeved on the wire winding shaft. A fixed rod 31 is arranged at the center of the inner wall of the outer disk 3, the fixed rod 31 is inserted at the center of the inner disk 2, and a bayonet 32 on the fixed rod 31 is clamped in a connecting groove 462 of the shifting block 46.

As shown in fig. 2 and 3, the wire spool 4 includes a left movable plate 41, a right movable plate 42, a fixed plate 43, a return spring 44, a shifting block 46, a left eccentric block 47, a right eccentric block 48, a left top block 49, and a right top block 410. The left movable disc 41, the right movable disc 42 and the fixed disc 43 are all arc-shaped discs and are sequentially connected to form an annular disc, the right end of the left movable disc 41 is hinged to the inner disc 2 and is connected with the left end of the fixed disc 43, the left end of the left movable disc 41 is connected with the left end of the right movable disc 42, the right end of the right movable disc 42 is hinged to the inner disc 2 and is connected with the right end of the fixed disc 43, and two ends of a reset spring 44 are respectively connected to the left movable disc 41 and the right movable disc 42; the shifting block 46 is fixed on a spool penetrating the center of the spool 4, a shifting fork 461 is installed on the outer wall of the shifting block 46 along the radial direction, a plurality of connecting grooves 462 are arranged on the outer end face of the shifting block 46, a left eccentric block 47 and a right eccentric block 48 are sequentially fixed on the inner end face of the shifting block 46, a left top block 49 is fixed on the inner side of the free end of the left movable plate 41 and is abutted against the left eccentric block 47, a right top block 410 is fixed on the inner side of the free end of the right movable plate 42 and is abutted against the right eccentric block 48, two limiting

blocks

The following are specifically mentioned: in this embodiment:

(1) the return spring 44 is an extension spring.

(2) The left top block 49 and the right top block 410 are both provided with a bearing 413, and the left top block 49 and the right top block 410 are respectively abutted against the left eccentric block 47 and the right eccentric block 48 through the bearing 413.

The utility model discloses a theory of operation:

1. before winding, the outer disc 3 is rotated, the bayonet 32 on the outer disc 3 drives the shifting block 46 to swing, the left eccentric block 47 and the right eccentric block 48 fixed on the shifting block 46 respectively abut against the left top block 49 and the right top block 410, so that the left movable disc 41 and the right movable disc 42 respectively swing outwards around the hinged point thereof, and the wire winding seat 4 is formed into a larger diameter.

2. After the winding is finished, the outer disc 3 is rotated reversely, the shifting block 46 is driven to rotate reversely, and under the combined action of the reset spring, the left movable disc 41 and the right movable disc 42 swing reversely around the hinged point of the left movable disc and the right movable disc respectively, so that the diameter of the winding seat 4 is reduced, and the finished winding can be taken down easily.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
