Hook Coupling

摘要

The invention discloses a hook coupling comprising a principal hook body and two blocking members disposed thereon to block any object inserted into the principal hook body. The hook coupling can make the inserted object (such as shoulder belts) to be very conveniently inserted into the hook coupling. In addition, after the shoulder belts are inserted, one blocking member can compress the shoulder belts, and the other blocking member can completely seal the clearance for inserting the shoulder belts, which result in the shoulder belts being not slid out from the hook coupling.

主权项

1. A hook coupling comprising:
a principal hook body which comprises a first flat and straight member and a second flat and straight member, and a first arc-shaped member and a second arc-shaped member that are connected with the first flat and straight member and the second flat and straight member respectively to form a flat ring-shaped element having a central hole therein; and a third flat and straight member which is connected to the second flat and straight member by a third arc-shaped member; wherein the hook coupling further comprises: a first blocking member extending downwardly toward the third flat and straight member, which is disposed on the second flat and straight member; and a second blocking member extending upwardly toward the second flat and straight member, which is disposed at one end of the third flat and straight member; and wherein a sharp angle between one side of one end of the second blocking member and the third flat and straight member is created for ease of insertion.
