Anti-falling device

摘要

An anti-falling device contains: a support rod including a hanging seat and ratchet teeth; two locking jaws, and each locking jaw having a fixing mount, a controlling member, and a spring; the fixing mount having a fitting orifice, an arcuate orifice, a receiving orifice, and a clamping hook. The fitting orifice is fitted with the support rod, the arcuate orifice passes through the fixing mount, the receiving orifice passes through the fixing mount, two clamping hooks of the two locking jaws are clamped on two end portions of an extending plate of a H beam. The controlling member is connected with the fixing mount and swings between a locking position and an unlocking position. The controlling member has a lock bolt and two apertures, and the two inserting bolts are inserted into the two apertures and the receiving orifice so as to limit the controlling member at the locking position.

1. An anti-falling device comprising:
a support rod including a hanging seat configured to couple with a safety rope on a worker, the support rod also including a plurality of ratchet teeth defined therein; two locking jaws fitted on two opposing ends of the support rod, and each locking jaw of said two locking jaws having a fixing mount, a controlling member, an inserting bolt and a spring; the fixing mount having a fitting orifice, an elongated arcuate orifice, a receiving orifice, and a clamping hook; the fitting orifice being polygonal and fitted with the support rod which passes through the fitting orifice, the elongated arcuate orifice passing through the fixing mount and communicating with the fitting orifice, the receiving orifice passing through two sides of the fixing mount adjacent to a top end thereof, the two clamping hooks of the two locking jaws being clamped on two end portions of an extending plate of an H beam, the controlling member being pivotally connected with respect to the fixing mount, the controlling member configured to pivot between a locked position and an unlocked position, the controlling member having a lock bolt inserted into the elongated arcuate orifice and having two apertures; when the controlling member is located in the locked position, the lock bolt engages with one of the plurality of ratchet teeth, and the two apertures linearly align with the receiving orifice in order to receive the inserting bolt; when the controlling member is in the locked position as the inserting bolt is inserted into the two apertures and the receiving orifice, the controlling member is prevented from pivoting and the fixing mount is prevented from moving in opposing directions along the support rod; when the inserting bolt is removed from the two apertures and the receiving orifice, and the controlling member is pivoted from the locked position to the unlocked position, the controlling member is pushed against the bias of the spring so that the lock bolt disengages from said one of the plurality of ratchet teeth and the fixing mount is allowed to move in the opposing directions along the support rod.
