Tension locking device for ring

Abstract

The invention relates to a tension locking device for earrings. The feature of this device is that an embossed protrusion is formed on one side of the plate spring of the tension locking device designed to be able to pick and hang earrings on the earlobe arbitrarily, and the fixing pieces formed on both sides of the tension locking device are formed by bending To fix and support the embossed protrusion, and make the embossed protrusion be movably clamped by the fixing piece, thereby not only preventing the separation or disengagement of the plate spring, but also preventing damage to the Stress concentration occurs locally on the fixed piece or the plate spring, fundamentally preventing the fixed piece on the tension lock device or the plate spring connected to the tension lock device from being partially broken. In addition, since the present invention can realize the tension action of the tension locking device with a small force, the feeling and effect when the user wears the earrings is improved.

Description

Technical field [0001] The present invention relates to a tension locking device, in particular to a tension locking device applied to earrings which can be freely hung on or removed from the earlobe. Background technique [0002] In general, earrings are roughly divided into two forms. One is earrings that can be used even without punching the earlobe, and the other is earrings that can be used without punching the earlobe. Most of these earrings have tension locks that make it easy to put on or take off the earrings. [0003] see Figure 4 and Figure 5 , which represents a prior art tension locking device used on earrings. [0004] like Figure 4 and Figure 5 As shown, the tension locking device 20 is integrally formed with a fixing hole 27 which can clamp and support the fixing end 16 of the earring body 10 on one end of the locking device body 22 . The other end of the locking device body 22 is bent toward the inside of the locking device body 22 , and a hinge hol...

Problems solved by technology

However, the above-mentioned supporting piece 24 does not actually fully play the role of dispersing the fatigue stress. In this prior art tension locking device 20, the fatigue stress generated due to the repeated tension of the plate spring 30 is basically concentrated. As the fixed fulcrum of the fixed piece 23 part, so the fixed piece 23 part is very prone to partial fracture, and because it is only pressed by the fixed piece 23, this not only weakens the fixing force to the plate spring 30, but also has The disadvantage of being unable to change or increase the tension force of the plate spring 30 on the tension locking device 20

[0007] Due to the above-mentioned shortcomings and problems in the prior art, when the tension locking device 20 is repeatedly used (rotating action), it often occurs that the tension force is reduced due to the fatigue limit of the fixed piece 23 and the plate spring 30, thereby reducing the earring. 1 performance, so that the earring 1 hanging on the earlobe is loose or even detached from the earlobe
