The present invention relates to a buckle of the industrial seat belt, and more specifically, the shape of the locking jaw in the form of "b" so as not to have a weak part in the locking jaw formed on the hook of the seat belt, but the "a" shape The locking jaw is formed to face each other at intervals, and the locking portion of the upper and lower locking pieces caught by the upper and lower locking jaws is also formed in an "a" shape so as to correspond to the locking jaw, thereby forming the locking jaw and the locking jaw. The vulnerable portion is removed from the locking portion to enable a strong locking action on the locking jaw and the locking portion, and to minimize the breakage of the locking jaw by a structure capable of a strong locking action as described above. Even when the locking jaw is broken, the other side of the locking jaw is caught in the locking portion to prevent the safety belt from being released while the safety belt is released.

Various types of buckle of the conventional industrial seat belts have been developed and used. Among them, the closest to the present design is the utility model registration No. 358446 (designation name: Industrial safety belt buckle: conventional designation). Known by the Shinan Gazette.

The prior art as described above, the hook consists of a hook and a locking device having a binding hole is fixed to both ends of the seat belt to be worn for the safety of the user in the industrial field, the hook is one side to the front The inclined locking step is formed to face up and down, and the locking device is to assemble the left and right casings having the same shape with the upper and lower fixing pins, forming an opening on one side of the casing, being supported by a spring inside and facing the same shape. The locking pieces are disposed to face each other so as to penetrate the fixing pins, and the locking piece is formed on one side of the locking piece to hold the locking jaw of the hook, and the other side is integrally formed as a button for dissociating the hook. In constructing a buckle of an industrial seat belt, a hook pin is disposed between the hook portion and the button portion. The rim piece forms a long hole so as to be slidable, one side of the spring is supported by the casing, and the other side is supported by the outside of the engaging portion of the locking piece.

Such a conventional design has a locking jaw formed at the top end of the hook is formed in the shape of a triangular arrow, the locking jaw is formed symmetrically to each other in the upper and lower parts of the locking jaw formed in the shape of a triangular arrow, and is formed at the rear between the upper and lower locking jaws. As the neck is formed in a narrow shape so that the width is significantly reduced than the upper and lower locking jaws, there is a problem in that the neck has a fragile structure that can be easily cut when the external force acts on the locking jaw. have.
