Bridge-adjustment fixing belt buckle

Abstract

A bridge-adjustment fixing belt buckle is provided, aiming to improve difficulty of adjustment and unstable fixing. A first bridge, which is rotatable, is arranged in conjunction with a spring and a raised pawl to achieve quick and stable fixing and tightness adjustment of a belt. To avoid accidental touch, the bridge is arranged to drive the raised pawl to disengage from the belt, and automatic position restoration is achieved by the elastic force of the spring. Outside appearance change made with an auxiliary bridge may change the position of triggering the raised pawl to provide flexibility for expansion of mechanical design and also maintaining smooth feel of adjustment. Also, a combination of a main limiting frame, a decorative panel control, and a connecting seat can be used to achieve horizontal push type operation, and a more accurate and stable tightness adjustment is achieved in conjunction with the belt ratchet.

I claim: 
     
         1 . A bridge-adjustment fixing belt buckle, comprising: a belt buckle seat; a first bridge, which is arranged on the belt buckle seat in a rotatable manner, a raised pawl extending from the first bridge for pressing against a belt; a spring, which is arranged between the raised pawl and the belt buckle seat for providing elastic bias of the raised pawl toward the belt; and a decorative panel control, which is connected to one side of the belt buckle seat, the other side of the decorative panel control being provided with a second bridge for providing guidance when the belt is inserted, wherein through rotation of the first bridge, the raised pawl is caused to disengage from pressing against the belt, thereby achieving adjustment of the belt. 
     
     
         2 . The bridge-adjustment fixing belt buckle according to  claim 1 , wherein the decorative panel control is provided, on one side thereof, with an auxiliary bridge, the auxiliary bridge being connected to and arranged at a center of the belt buckle seat; and the decorative panel control is provided, on the other side thereof, with a second bridge, the second bridge providing guidance for insertion of the belt; and the first bridge is arranged on one side of the belt buckle seat adjacent to an edge thereof in a rotatable manner, and the raised pawl is caused to release a state of pressing against and fixing the belt by pushing and moving the first bridge, so as to perform an adjustment operation on the belt. 
     
     
         3 . A bridge-adjustment fixing belt buckle, comprising: a belt buckle seat, of which a center is pivotally connected to a decorative panel control, a second bridge and an auxiliary bridge being respectively provided on inner sides of two ends of the decorative panel control, and a limiting groove being provided between the second bridge and the auxiliary bridge; a first bridge, which is pivotally provided on two sides of a convex portion on outside of the belt buckle seat, the first bridge being operable to drive a spring arranged in the belt buckle seat to press against a raised pawl, an arc-shaped portion being provided on an edge of the first bridge, the arc-shaped portion cooperating with the convex portion to enable smooth rotation of the first bridge within a specific angle, so that to adjust tightness of a belt, the first bridge is pushed and rotated to allow the raised pawl to release a fixed state of the belt, and when the adjustment is completed, the spring restores position to fix. 
     
     
         4 . The bridge-adjustment fixing belt buckle according to  claim 3 , wherein a thickness of the limiting groove is greater than a thickness of the first bridge. 
     
     
         5 . The bridge-adjustment fixing belt buckle according to  claim 3 , wherein the decorative panel control is further provided with a third bridge, the third bridge being arranged in parallel with the second bridge. 
     
     
         6 . A bridge-adjustment fixing belt buckle, comprising: a main limiting frame, which is provided with a main limiting groove at a center thereof, the main limiting frame having one side that is provided with a first bridge and the other side provided with a connecting portion, the main first bridge being provided for extension of a belt; a decorative panel control, which comprises a main shaft rod and a decorative panel portion, a main shaft rod raised pawl extending from the main shaft rod, a spring being arranged on a bottom of the main shaft rod, the decorative panel control being arranged in the main limiting groove; a connecting seat, which has one side that is provided with a pivoting portion for connection with the main shaft rod and the other side provided with a positioning groove, a connecting groove being provided on an upper side of the connecting seat for connection with the connecting portion, a positioning member being embedded in the positioning groove, the main limiting frame being completely fixed to the connecting seat and also forming a main second bridge on one side opposite to the main first bridge, so that a wearer is allowed to take a horizontally pushing measure to control the decorative panel control to drive the main shaft rod raised pawl cooperating with multiple ratchet teeth arranged on a belt for pressing and positioning, so as to make adjustment of tightness of the belt between the main first bridge and the main second bridge easy and stable. 
     
     
         7 . The bridge-adjustment fixing belt buckle according to  claim 6 , wherein a width of the decorative panel control is less than a width of the limiting groove to ensure that an elastic force provided by the spring is sufficient to drive the decorative panel control for adjustment operation.
