Rotation type multifunctional bottom tooth spring piece mechanism

Abstract

The invention provides a rotation type multifunctional bottom tooth spring piece mechanism. The rotation type multifunctional bottom tooth spring piece mechanism comprises a watchcase disc, a rotating watch bezel cover and a rotation type multifunctional bottom tooth spring piece; the upper surface of the watchcase disc is provided with a fixing containing groove and a circular fixing hole; the fixing point of the rotation type multifunctional bottom tooth spring piece is fixed into the circular fixing hole at the plane of the bottom portion of the containing groove; the rotating watch bezel cover is located at the containing groove of the watchcase disc; the rotation type multifunctional bottom tooth spring piece is located between the watchcase disc and the rotating watch bezel cover; the rotation type multifunctional bottom tooth spring piece is flat and waved; the surface of the rotation type multifunctional bottom tooth spring piece is provided with a spring piece upwarp point; and the bottom portion of the rotation type multifunctional bottom tooth spring piece is provided with a circular fixing point. The rotation type multifunctional bottom tooth spring piece mechanism enables the gap and returning position between the watchcase disc and the rotating watch bezel cover to be reasonably adjusted, thereby enabling the returning position between the watchcase disc and the rotating watch bezel cover to achieve a better effect, and increasing the accuracy of a dial plate; and at the same time, the rotation type multifunctional bottom tooth spring piece mechanism has the advantages of being high in elasticity, strong in stability, long in service life, more silvery in rotation sound, and easy in processing and assembling, etc.

Description

technical field [0001] This patent relates to a rotary watch, in particular to the structure of a rotary bezel cover mechanism for a rotary watch. Background technique [0002] A watch, or a wristwatch, refers to an instrument worn on the wrist for timing / displaying time. Watches usually use ceramic straps, tungsten steel straps, titanium pottery straps, stainless steel straps and other straps to connect with the "case plate" that displays the time, and tie it on the wrist. With the development of science and technology and people's pursuit of unique personality, more and more attention has been paid to the diversity, decoration and multifunctionality of watches, and various novel styles of watches have appeared, as can often be seen in real life. A watch whose bezel cover can be rotated is an example. Functional watches such as sports watches, diving watches, military watches, and ordinary watches often have this feature. However, in the field of rotary watches, there are ...

AI Technical Summary

Problems solved by technology

[0006] 2. The surface of the traditional rotating bottom shrapnel is flat, with no elasticity or very low elasticity

[0007] 3. The frame of the traditional rotating bottom tooth shrapnel ring is a fixed frame, but when the shrapnel warping point on the front of the shrapnel and the bottom bending fixed point are punched by traditional processing, the shrapnel warping point and the bending fixed point account for one-third of the entire shrapnel ring frame The second area will deform the frame surface of the shrapnel, and the plane of the shrapnel after assembly is not conducive to assembling on the plane of the accommodating groove or the case plate, which will ultimately affect the assembly efficiency and assembly effect

[0008] 4. It is difficult to obtain consistent and precise dimensions for the three shrapnel warping points or two shrapnel warping points of the traditional rotating bottom teeth shrapnel during stamping and manufacturing

[0009] 5. When the shrapnel of the traditional rotating bottom tooth rotates, it is difficult to synchronize the warping points of the three shrapnels or the two shrapnels, and the return between the case plate and the rotating bezel cover is relatively large, which is easy to shake, thus affecting the dial. accuracy

[0010] 6. When the traditional rotating bottom tooth shrapnel three shrapnel warping points or two shrapnel warping points rotate synchronously, it is difficult to achieve consistent sound

[0011] 7. The life of the traditional rotating bottom tooth shrapnel is between 2000 and 3000 times, which is short and not resistant to fatigue

[0012] 8. The fixed point at the bottom of the traditional rotating bottom tooth shrapnel forms a flat and bent shape after punching, while the fixed hole in the case plate accommodation groove is designed as a round hole structure, which is not conducive to the circular shape of the case plate accommodation groove. Fixing hole connection and fixing
