Among them, the vacuum cup cover is one of the most important parts, which has the functions of sealing, heat insulation and the like.
[0003] Nowadays, most of the vacuum cup covers on the market are made of titanium alloy or stainless steel as the cover cover, and plastic as the cover. The titanium alloy or stainless steel and the plastic are directly interference press-fitted, or a decorative ring is added to the gap between the two materials and then interference press-fitted, so as to achieve the purpose of connecting the two different materials. However, there is a common shortcoming that interference press-fitting is easy to fall off under the change of high and low temperature, resulting in low quality of the vacuum cup. Secondly, there is also a situation that the cover is entirely made of plastic, and a spin riveting edge covering structure is used to connect the cover cover and the cover. However, in the case of spin riveting edge covering, the cover edge is not smooth, which is easy to hide dirt and cause hygiene problems. At the same time, the plastic part is easy to deform and scratch, and the practicability is not strong. SUMMARY

The titanium alloy connecting structure adopts a double titanium cover design, and a rotation stopping ring is additionally arranged on the plastic cover. The technical problem that the connection is not firm due to too large temperature difference between the inner titanium ring and the outer titanium ring during welding can be effectively overcome, and the quality of the titanium alloy cup cover can be effectively improved.
[0005] A titanium alloy plastic connecting mechanism comprises an outer titanium cover, a rotation stopping ring is additionally arranged between the outer titanium cover and a plastic cover, the rotation stopping ring is pressed into an annular groove of an outer ring of the plastic cover, an inner titanium ring is arranged between the rotation stopping ring and the outer titanium cover, the inner titanium ring is point-welded with the rotation stopping ring, and the outer titanium cover is interference press-fitted on the inner titanium ring and laser-welded with a lower edge of the inner titanium ring.
[0006] As a preferred technical solution of the above, the upper and lower ends of the inner titanium ring are respectively engaged with variable cross-sections of the plastic cover.
[0007] As a preferred technical solution of the above, the lower edge of the inner titanium ring is wrapped around the lower edge of the plastic cover after being bent inward twice by 90 degrees.
[0008] As a preferred technical solution of the above, the upper edge of the inner titanium ring is wrapped around a variable-diameter boss of the upper edge of the plastic cover after being bent inward once by 90 degrees.
[0009] As a preferred embodiment of the above technical solution, the outer ring of the plastic cover is smooth, and the inner ring is threaded.
[0010] A titanium alloy cup lid, employing any of the aforementioned titanium alloy plastic connecting mechanisms, wherein a plug assembly is riveted to the inside of the plastic lid.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. An anti-rotation ring is added, and the titanium alloy workpiece and the plastic workpiece are connected together by laser welding, so that the titanium alloy and plastic are integrally formed, which improves the strength of the connection.
[0013] 2. It adopts a double titanium cap design, with each layer made of titanium alloy, which further reduces heat transfer and thus achieves a scalding prevention effect.
[0014] 3. The cup lid is made of titanium alloy and plastic composite. The titanium plate 1, titanium plate 2 and some parts of the stopper assembly are made of titanium alloy, while the plastic cap is made of plastic. The threads are set on the plastic cap. This structure can effectively prevent noise caused by metal contact when the all-titanium cap is used. Attached Figure Description
