Technical Field

[0001] This utility model relates to the field of coating technology, specifically to a stress buffer structure for sealing the mouth of a titanium cup with a lead-free glass ring. Background Technology

[0002] Titanium was used as a white pigment in ancient times, but its use as a monomeric metal began after World War II. In short, titanium's advantages are: lightness, strength, and rust resistance. Although titanium's specific gravity is two-thirds that of steel, its strength is the same, and its corrosion resistance is outstanding. These properties were previously mostly used in jet aircraft and satellite equipment. In recent years, with research and development, its harmless properties to humans have been discovered, and since the beginning of the new century, it has gained attention as a new material widely used in the medical field, decorative arts, and other sectors.

[0003] The mouth of a titanium cup is usually sealed with a lead-free glass ring. During this process, due to the different coefficients of thermal expansion of titanium and glass, stress problems exist, which makes the sealing joint prone to cracking or reduced sealing performance, thus making it impossible to guarantee product quality.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

The holding mechanism includes a titanium cup, the top of which is provided with an annular wave groove. The inner wall of the annular wave groove is sprayed with a transition coating. The top of the titanium cup is provided with a glass ring, the bottom of which is adapted to the annular wave groove.

[0007] By adopting the above technical solution, an annular wavy groove is formed at the mouth of the titanium cup through precision CNC machining or laser etching. Then, a silicon oxide transition coating is deposited on the inner wall of the annular wavy groove by chemical vapor deposition. Finally, the molten glass ring is snapped onto the top of the annular wavy groove, thereby completing the sealing operation. During the entire sealing process, the annular wavy groove prevents stress concentration, and the transition coating ensures the wettability of the glass with titanium when it melts, effectively buffering stress and stabilizing product quality.

[0008] In a preferred embodiment, the present invention can be further configured such that: a correction mechanism is provided on the outer side of the titanium cup, the correction mechanism including a clamp that is interference-fitted to the outer side of the titanium cup, a binding strap connected to one end of the clamp, and a protrusion connected to the outer wall of the clamp, wherein the binding strap is engaged with the protrusion.

[0009] In a preferred embodiment, the present invention can be further configured such that: the clamp is a ring with a notch, the connection between the binding strap and the clamp is located on one side of the notch, and the protrusion is located on the other side of the notch.

[0010] In a preferred embodiment, the present invention can be further configured such that the vertical cross-section of the annular wave groove is set to a U-shape.

[0011] In a preferred embodiment, the present invention can be further configured such that the transition coating is made of silicon oxide material and the thickness is set to 5-10 μm.

[0012] In a preferred embodiment, the present invention can be further configured such that the roughness of the transition coating is set to Ra 0.8-1.6 μm.

[0013] In a preferred embodiment, the present invention can be further configured such that a handle is installed on one side of the titanium cup, and the handle is located at the bottom of the notch.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, an annular wavy groove is formed at the mouth of the titanium cup by precision CNC machining or laser etching.

The bottom of the glass ring 140 is adapted to the annular wave groove 120.

[0029] Furthermore, the vertical cross-section of the annular wave groove 120 is set as U-shaped. The U-shaped design can concentrate the stress at the sharp angle of the wall, thereby achieving the purpose of buffering stress during the sealing operation.

[0030] Furthermore, the transition coating 130 is made of silicon oxide material with a thickness of 5-10 μm. The silicon oxide transition coating 130 ensures the wettability of the glass with titanium when it melts.

[0031] Furthermore, the roughness of the transition coating 130 is set to Ra0.8-1.6μm. Adjusting the roughness can enhance the mechanical anchoring effect of the glass.

[0032] Example 2:

Before the sealing operation begins, the clamp 210 is fitted onto the opening of the titanium cup 110, and then the binding strap 220 and the protrusion 230 cooperate to fix the clamp 210. Then, the glass ring 140 fits against the inner wall of the clamp 210 and connects with the annular wave groove 120, effectively guiding the glass ring 140 and ensuring the sealing effect.

[0034] Furthermore, the clamp 210 is configured as a ring with a notch, the connection between the binding strap 220 and the clamp 210 is located on one side of the notch, and the protrusion 230 is located on the other side of the notch. The shape design of the clamp 210 makes it easy to fit on the outside of the titanium cup 110.

[0035] Example 3:

[0036] Combination Figure 1 As shown, in the above embodiment, a handle 300 is installed on one side of the titanium cup 110. The handle 300 is located at the bottom of the notch. The handle 300 makes it convenient for the operator to hold the titanium cup 110, thereby improving the comfort of using the product.

[0037] The working principle and usage process of this utility model are as follows: A ring-shaped wavy groove 120 is formed at the mouth of the titanium cup 110 by precision CNC machining or laser etching.
