<p>The present invention relates to the technical field of locking devices for a tube winding apparatus, particularly to a locking device for an automatic tube winding apparatus. Whereas the ratchet locking device for the tube winding apparatus in the prior art is not able to lock a flexible tube or cable in any position and can only lock the flexible tube or cable periodically, and the locking operation of it is not easy, the present invention provides a locking device for an automatic tube winding apparatus, which can lock the flexible tube or cable in any position conveniently and easily during the winding or rewinding operation. The locking device includes a connector rotating shaft, housing, and a grooved cylindrical cam assembly. A projection is provided on the wall of an inner hole in said housing. Said grooved cylindrical cam assembly includes a grooved cylindrical cam, a spring and a transmission sleeve. An A-shaped groove engagable with said projection is provided on the outer surface of said grooved cylindrical cam. Said grooved cylindrical cam assembly is disposed in the inner hole in said housing, and said connector rotating shaft is inserted in the inner hole of said transmission sleeve.</p> |
