Abstract

A clip-on belt buckle, including a buckle part and a connecting part. A fixed end of a belt is fixedly connected to the connecting part. The buckle part includes a buckle body, a first clamp plate and a second clamp plate. An upper end and a lower end of the buckle body are provided with an oblique hole, respectively. An upper part and a lower part of a back of the buckle body are provided with a sliding groove, respectively. Centers of an upper end and a lower end of the first plate are provided with an elongated hole along a front-and-back direction, respectively. A vertical shaft is provided at a middle of the second plate. Two ends of the vertical shaft extend through the elongated holes, and then extend through the oblique holes. A movable end of the belt is inserted between the first plate and the second plate.

First claim

What is claimed is:

1. A clip-on belt buckle, comprising:
a buckle part;
a connecting part; and
a pin shaft;
wherein a fixed end of a belt is fixed on the connecting part; the buckle part is movably connected to the connecting part by the pin shaft; the buckle part comprises a buckle body; a first elongated hole is provided at an upper end of the buckle body; a second elongated hole is provided at a lower end of the buckle body; an axis of the first elongated hole is oblique along a left-and-right direction; an axis of the second elongated hole is oblique along the left-and-right direction; an end of the first elongated hole close to the pin shaft is close to a human body in use; an end of the second elongated hole close to the pin shaft is close to the human body in use; a first sliding groove is provided on a upper part of a back of the buckle body; a second sliding groove is provided on a lower part of the back of the buckle body; the first sliding groove and the second sliding groove have the same width and are arranged along the left-and-right direction;
a first clamp plate is arranged behind the buckle body; a third elongated hole is arranged at a middle of an upper end of the first clamp plate; a fourth elongated hole is arranged at a middle of a lower end of the first clamp plate; an axis of the third elongated hole is arranged along a front-and-back direction; an axis of the fourth elongated hole is arranged along the front-and-back direction; the upper end of the first clamp plate is embedded in the first sliding groove and is slidable along the left-and-right direction; the lower end of the first clamp plate is embedded in the second sliding groove and is slidable along the left-and-right direction; a front surface of the first clamp plate abuts against a back surface of the buckle body and is slidable along the left-and-right direction; a second clamp plate is arranged behind the first clamp plate; a vertical shaft is arranged at a middle of the second clamp plate; an upper end of the vertical shaft is inserted into the third elongated hole and the first elongated hole; a lower end of the vertical shaft is inserted into the fourth elongated hole and the second elongated hole; the vertical shaft, the third elongated hole and the fourth elongated hole are together configured to control the first clamp plate and the second clamp plate to slide synchronously in the first sliding groove and the second sliding groove; the vertical shaft, the first elongated hole and the second elongated hole are together configured to control the second clamp plate to move close to or away from the first clamp plate during a synchronous sliding along the left-and-right direction;
when the belt is fastened, a movable end of the belt is inserted between the first clamp plate and the second clamp plate from right to left by means of a right hand of a user, and a tightness of the fastening is adjusted; the vertical shaft is slid to the right by a hand, such that the first clamp plate and the second clamp plate clamps the belt to slide synchronously to the right in the first sliding groove and the second sliding groove; meanwhile, the vertical shaft moves forward along the first elongated hole and the second elongated hole to drive the second clamp plate to move forward such that the second clamp plate and the first clamp plate clamp the belt;
when the belt is untied, the buckle body is fixed by the right hand, and the movable end of the belt is pulled to the left by a left hand, such that the belt drives the first clamp plate and the second clamp plate to slide synchronously to the left along the first sliding groove and the second sliding groove; meanwhile, the vertical shaft moves backward in the first elongated hole and the second elongated hole to drive the second clamp plate to move backward such that the second clamp plate and the first clamp plate are separated; then the buckle body is held by the left hand, and the movable end of the belt is pulled out from between the first clamp plate and the second clamp plate by the right hand.
