Description

Belt buckle {The buckle of waist belt}

The present invention relates to a belt buckle, in particular to a belt buckle in which the component has a simple shape, the manufacturing cost is low, and the elasticity for operation is kept constant for a long time.

The belt used to prevent the pants from flowing down is composed of a belt that is fitted to the pants to wind the wearer's waist, and a buckle provided at one end of the belt to accommodate the other end of the belt to temporarily fix the belt.

Among these buckle, there is a one-touch belt that can finely adjust the tightening state of the belt, and the tightening and loosening operation of the belt is easy.

As one of the belts according to the prior art, the Republic of Korea Utility Model Seal No. 0110233, as shown in Figure 5, integrally formed with a flange 21, the shaft hole 25 is formed on the back surface of the buckle body 20 In the shaft hole, the rotating member 29 having a plurality of fixing projections 28 are elastically installed by the shaft 32 and the spring 33 so that the fixing protrusion is in close contact with the belt, the handle to the shaft 32 The lever 31 with the rotary member 29 is installed together with the rotary member 29 and the handle 30 is positioned in the space portion 27 of the flange 21 so that the rotary member rotates by the rotation operation of the lever. The configuration is described as possible.

As a result, the rotating member 29 is elastic and rotated. When the belt is inserted into the buckle main body 20, the rotating member rotates elastically. After receiving the belt, the rotating member 29 rotates in reverse by restoring force to press the belt to the buckle main body. Then, after the wearer operates the handle 30 to rotate the rotating member 29 again, the pressing force on the belt is released so that the belt can be released.

In this conventional technique, the spring 33 is composed of a coil spring fitted along the outer circumferential surface of the shaft 32 to press the rotating member 29 and the lever 31 by elasticity of the spring 33. .

In this prior art, the elastic deformation of the spring according to the manipulation of the handle is mainly made at the upper end of the spring, and the frequent elastic deformation of the spring has a problem of weakly deforming the elasticity of the upper end. In other words, the buckle according to the prior art has a problem that the elasticity of the spring gradually weakens when used for a long time, so that the fixing force of the belt is reduced by weakly pressing the belt to the buckle body.

In addition, in order to fix the cylindrical shaft in the shaft hole, grooves are formed at the ends of both shafts, and fixing pins larger in diameter than the shaft holes are fixed to both ends of the shaft inserted in the shaft hole, so that the shaft does not fall out of the shaft hole.

At this time, the assembling operation of forming grooves on the upper and lower ends of the shaft and fixing the pressing pins to the grooves is difficult to form the grooves due to the small diameter of the shaft, which leads to an increase in the manufacturing cost. There is a problem with this deterioration.

On the other hand, in order to improve the assembly and reinforce the resilience, the Republic of Korea Utility Model Registration No. 0239247 registered and filed by the applicant in advance, as shown in Figure 6, the rotating body having a locking piece and the stopper and the pressing portion, In the rotating device of the buckle consisting of a buckle body having a lower through hole, a spring holding part 24 having a spring fixing part 22 is formed on the rotating body 20, and the spring holding part 24 is provided.

To form a support surface, to form an arc on one side outside the locking piece The rotation device of a buckle consisting of a packing (46) by integrally formed to the injection molding is described.

In this still another conventional technique, the lower part of the rotating body has a disadvantage that the manufacturing cost is expensive due to the complicated shape of the spring bearing part provided with the spring fixture 22.

That is, forming a groove recessed at the bottom of the rotating body, the spring fixture is formed in the center groove so that the upper bent end of the spring can be inserted into the inner surface of the groove spaced apart from the circumferential surface formed by the inner wall, so as to project downward It must be formed.

The spring bearing part having such a complicated shape must maintain a very small tolerance for accurate assembly, and accordingly, the manufacturing cost is increased.

In addition, the lower projection 34 of the adjustment portion has a fixed surface 38 to be fitted so as not to rotate in the lower through hole, while the upper projection 32 is not formed such a fixed surface 38 is formed. . That is, the adjuster 36 has directionality due to the difference in shape of the upper and lower protrusions formed at the upper and lower sides, and it is not easy to assemble the adjuster which is a small accessory in assembling the rotation apparatus according to the prior art. have.

Moreover, the stopper 60 provided in the outer lower end of the rotating body 20 should fix a small stopper to the rotating body by folding. If the stopper's welding position is different, it is easy to cause product defects that the packing of the rotating body cannot press the belt properly.If the force is applied to the stopper as the belt is pulled while wearing, the stopper is rotated because the strength of the stopper is weak. There is also a problem in that the life of the product is reduced by being easily separated from the product.
