Description

Body buckle structure

The invention relates to a buckle, in particular to a belt fastener structure which can ensure that the connected belt body is not cut off and the safety is improved.

According to the current general use of the belt, the fasteners are used for connection, and the belt body can be adjusted in length, movable connection, etc., so the use of the buckle is very common, and different types of fasteners, due to structural differences, The way of holding is different, the operation is different, and the use will be different.

As shown in the seventh, eighth and ninth figures, it is a belt fastener structure for a conventional activity connection, comprising: a male fastener 10 and a female fastener 20, the male fastener 10 is internally provided with two The belts 101 and 102 are disposed, and a supporting rail 103 is disposed between the two belt holes 101 and 102, and the belt body 30 is pierced by the two belt holes 101 and 102, so that the belt body 30 is wound around the support. The cross member 103 is connected to the connecting member. The female fastening member 20 is provided with a through hole 201, and the other connecting body 201 is connected. The through hole 201 is used for the male fastener 10 to penetrate longitudinally. The member 10 is placed in a lateral direction so that the male fastener 10 and the female fastener 20 overlap each other, and the width of the male fastener 10 is greater than the width of the through hole 201, thereby preventing the male fastener 10 self-relaxing from the female fastener 20.

However, the above-mentioned belt fastener structure is due to the male fastener 10 and the use thereof. The female fasteners 20 are superposed on each other, and the supporting crossbars 103 of the male fasteners 10 and the through holes 201 of the female fasteners 20 are formed with opposite shearing edges 104 and 202, so that the male and female fasteners are When the 10 and 20 connected strips 30 and 40 are pulled in the opposite direction, the strip 30 connected to the male fastener 10 is subjected to relative shearing by the shearing edges 104 and 202, so that the male fastener is obtained. The 10 connected strips 30 have a truncated flaw and there is a certain risk.

Therefore, the manufacturer has a sleeve on the support rail 103 of the male fastener 10 of the above-mentioned belt fastener structure, and the sleeve is reduced by the sleeve, but the shearing force of the belt 30 is reduced. A sleeve member, and a plurality of machining programs for assembling the sleeve to the male fastener 10 supporting the crossbar 103, resulting in an increase in manufacturing cost, and the belt body 30 is still subjected to the male fastener 10 and the female fastener member 20 The relative shear, so it is still truncated.

The inventors of the present invention have come to the present invention in view of the shortcomings of the above-described conventional belt buckle structure, the idea of designing and testing, the multi-party investigation and trial sample test, and the multiple corrections and improvements.

The invention provides a belt buckle structure, comprising: a male fastener and a female fastener, the male fastener is a one-piece body, and the male fastener is provided with two wearing holes inside, the two wearing holes a support rail is disposed in the middle, and the first strap is disposed through the two strap holes, so that the first strap is connected to the support rail, and the female fastener is a one-piece body having a first surface, a second surface opposite to the first surface, a first force receiving end, and a second force receiving end opposite to the first force receiving end, the female fastener is provided with a penetrating portion The first force receiving end is connected with a second belt body, and the female fastener member is provided with at least one convex surface toward the first surface between the through hole and the second force receiving end. a protruding portion, the through hole is configured for the male fastener to be inserted into a buckle connection with the female fastener, so that the male buckle The piece and the female fastener are formed with a pitch by the height of the convex portion.

The main object of the present invention is to prevent the male and female fasteners from being pulled in the opposite direction when the male and female fasteners are forced to the opposite direction without increasing the components and the processing procedure. The first belt body connected by the male fastener is relatively sheared by the male fastener and the female fastener, ensuring that the first belt body connected by the male fastener is not cut off, and the safety of use is improved.

Referring to the first, second, third, fourth and fifth figures, the present invention provides a belt buckle structure comprising: a male fastener 1 and a female fastener 2, the male The fastener 1 is a stamped and formed sheet-like body, and the male fastener 1 is internally provided with two through-holes 11, 12, and a supporting crossbar 13 is disposed between the two wearing holes 11, 12, and the two wearing belts are provided The holes 11 and 12 are provided for a first belt body 3 so that the first belt body 3 is wound around the support rail 13 The female fastener 2 is a stamped and formed sheet-like body having a first surface 21, a second surface 22 opposite to the first surface, a first force receiving end 23 and a first surface The second receiving end 24 of the receiving end 23 is provided with a through hole 25 extending through the first surface 22 and the second surface 23, and a second belt is connected to the first receiving end 23 The through hole 25 is provided for the male fastener 1 to pass through and is limited to the first surface 21 of the female fastener 2, and the through hole 25 of the female fastener 2 is disposed between the second force receiving end 24 Two circular convex portions 26 are punched from the second surface 22 toward the first surface 21, and the circular convex portions 26 can be collectively punched when the female fastener 2 is stamped and formed. After the male fastener 1 is inserted in the longitudinal direction, the male fastener 1 is placed in a lateral direction, so that the male fastener 1 and the female fastener 2 are stacked by the height of the convex portion 26 to form a stack A. And by the male fastener 1 being limited to be snapped on the first surface 21 of the female fastener 2, the male fastener 1 can be prevented from being loosened from the female fastener 2 by itself.

In use, as shown in the sixth figure, the first and second belt bodies 3, 4 connected by the male and female fasteners 1, 2 are forced to be pulled in opposite directions, at this time, the male fastener 1 and the female fastener are The first strip 2 connected to the male fastener 1 is not subjected to the relative shearing of the male fastener 1 and the female fastener 2, and can be avoided by the height of the projections 26. The first strap connected to the male fastener has a truncated jaw.

Furthermore, the number of the convex portions 26 in which the female fastener 2 is stamped from the second surface 22 toward the first surface 21 may be one or two or more, and the convex portion 26 is also circular as described above. It can be other shapes such as elongated, elliptical, square, and the like.

It can be seen from the above that the belt buckle structure of the present invention can connect the male and female fasteners 1, 2 by the heightening action of the convex portion 26 on the female fastener 2 without adding components and processing procedures. When the first and second belt bodies 3, 4 are forced to pull in the opposite direction, the male fastener 1 and The distance between the female fasteners 2 and the female fasteners 2 is ensured by the spacing A, and the male fasteners 1 and the female fasteners 2 are prevented from being relatively sheared by the male fasteners 1 to ensure the male fasteners. 1 The first belt body 3 connected is not cut off, and the safety of use is improved, thereby making the product more competitive.
