Abstract
The invention discloses a self-locking eccentric clamping mechanism for an inertia cylinder. The self-locking eccentric clamping mechanism comprises eccentric mechanism seats, wherein the eccentric mechanism seats are arranged at the two sides of the upper end surface of a top cover of the inertia cylinder, the side wall of an inertia cylinder body is correspondingly provided with locks, an eccentric cam is arranged in each eccentric mechanism seat, and consists of two coaxial cylinders with different diameters, the large cylinder and the small cylinder of each eccentric cam are respectively provided with an eccentric through hole, the interior of each eccentric through hole is hinged to a pin shaft, the two ends of each pin shaft are horizontally arranged in two pin shaft holes which are formed in the corresponding eccentric mechanism seat, the large cylinder of each eccentric cam is provided with a handle, and a lock hook sheaths the small cylinder of each eccentric cam. Under the locking condition, each lock is hooked by the corresponding lock hook, and the lower plane of each large cylinder is in interference fit with the upper plane of the corresponding eccentric mechanism seat. The self-locking eccentric clamping mechanism has the advantages that the traditional bolt fixing method is replaced; the top cover of the inertia cylinder is locked with the inertia cylinder body by only rotating the handles; as the self-locking function is realized, the looseness of the top cover is avoided when the inertia cylinder runs, and the effects of quick operation and safety running of equipment are realized.
