A buckle including a female body (1) formed with a flat housing (3) and a male body (2) having a pair of right and left flexible insertion legs (30), being characterized in that when the female body (1) and the male body (2) are inserted to engage, the butting surfaces between the female body (1) and the male body (2) on a plane, that is, butting portions (15, 38) are formed with horizontal straight portions (11, 33) on both sides of the butting portions (15, 38) as well as a concave portion (12) at the center in the female body (1) and a convex portion (34) in the male body, or a convex portion (34) in the female body (1) and a concave portion (12) in the male body (2) continuously formed, so as to join the female body (1) to the male body (2) in the condition closely in contact.

Description

technical field [0001] The present invention relates to belt buckles for tightening belts, comprising a female part formed with a flat shell and a male part having a pair of bendable prongs which can be inserted into the shell of the female part and engaged therein. Background technique [0002] As is well known, a conventional plug-in type buckle comprises a female part, i.e. a female body formed with a flat shell, and a male part, i.e. a male body having a pair of bendable prongs which, when engaged with the male body and the female body, simply The straight line forms the butt joint of the female body and the male body. Such as Figure 28 As shown, a well-known buckle, it processes the insertion opening 7' of the flat shell 3' of the female body 1' into a straight shape, so that the front end of each side frame on both sides of the outer frame 20' of the belt threading part The edge of the insertion opening 7' of the housing 3' is contacted in the male body 2', and the t...

Problems solved by technology

In the case of the above buckle, when the female body 1' and the male body 2' are matingly engaged, the buckle clicks and lacks stability, and furthermore, when the prongs 30' are inserted into the housing, it is not expected that only the center The guide 35' at the place to get a smooth insertion operation

[0005] like Figure 29 As shown in the buckle, because when the pin 30 "of the male body 2" is inserted into the shell 3" of the female body 1", the straps at the ends of both sides of the buckle keep the gap between the female body 1" and the male body 2". On the mating surfaces, there will be any gaps on the right and left that will cause the female body 1" and male body 2" to slide and cause rattling issues
