Abstract
The utility model concerns a locking device of wire spool of enameling machine. The locking device is characterized in that: A centre is provided outside of wire spool. On the upper end of the centre, there provides a stepped bore. The profile of the stepped bore is of the shape of conical surface. The top of the centre is tightened with a spring housing. Within the spring housing, there provides a locking sleeve. The upper end of the spring housing interference fits with the locking sleeve. The lower end of the spring housing forms a space with the locking sleeve. Within the space, there provides a spring. On the lower end of the locking sleeve, there provides two bulges. Several locking balls are provided under both of the two bulges. The locking balls are fitted closely with on the position of steps of the stepped bore of the centre. One end of the spring is fixed on the spring housing, while another end is connected to the bulge of the locking sleeve. A ring-pull is provided on the upper end of the locking sleeve. A check ring is provided between the ring-pull and the locking sleeve. The utility model is used on the slender end of the wire spool. It can fasten the centre and make the wire spool more stable and can prevent loose.
