Description

  The present invention relates to a buckle for a belt, and more particularly, to a pinned buckle with an adjustable belt length.

  A pin type buckle is a type of buckle that wraps a belt around an object to be worn, such as the waist of the body, and fastens and fixes the belt to the object to be worn by inserting a retaining pin of the buckle into the retaining hole at the tip of the belt. Some pinned buckles have adjustable belt lengths.

  And most of the conventional pinned buckles with adjustable belt lengths have a locking piece that clamps the belt base end in cooperation with the side wall of the base member with a U-shaped cross section. A belt base end fixing portion that is attached to the belt, and a stop pin that can be inserted into a stop hole at the front end portion of the belt at one side portion of the rectangular frame body. A belt front end locking portion made of a pivotable attachment is connected by an intermediate belt.

  However, this conventional pinning type buckle has a drawback that the manufacturing cost is increased because the number of parts is large and the assembly is not easy. For this reason, it has been proposed in the prior art that the connecting belt is omitted from the conventional pinning type buckle and the frame of the belt front end locking portion is directly connected to the base member of the belt base end fixing portion ( For example, refer to Patent Document 1), and it cannot be said that the reduction of the number of parts and the manufacturing cost is sufficiently achieved.
