Description

A kind of metal shell glass outer

Technical field

The utility model relates to the technical field of glass, in particular to a kind of metal shell glass outer.

Background technique

Watchcase typically refers to the case member of wrist-watch main body, effect be contain and protect wrist-watch inherent component watch core, Dial plate, indicator etc..But existing watchcase is substantially using metal shell, and metal shell does not simultaneously have enlarging function, so that aobvious The font or pointer shown show smaller.

For this purpose, we have proposed a kind of metal shell glass outer with amplification effect.

Utility model content

The main purpose of the utility model is to provide a kind of metal shell glass outers, are in anticollision, watch core The advantages of existing amplification effect.

To achieve the above object, the utility model provides a kind of metal shell glass outer, using nano-glass material The glass outer thick middle thin edge, the bottom of the glass outer is concave shaped, and the face of the glass outer is outer Convex.

Preferably, the cutting plane of the glass outer includes first segment, second segment and third section, the first segment, second Section and third section are sequentially connected.

Preferably, the second segment even width, as far from described in the second segment to the close second segment direction First segment width gradually increases, by gradually increasing far from the second segment to the third section width close to the second segment direction Add.

Preferably, the first arc surface on the inside of the first segment, the second arc surface on the inside of the third section with it is described The medial surface of second segment is tangent, the 4th arc surface on the outside of third arc surface, the third section on the outside of the first segment with The lateral surface of the second segment is tangent.

Preferably, the reflectivity of the glass outer is less than 2%.

Compared with prior art, the utility model has the following beneficial effects: the glass outer uses nano-glass material It is fabricated, because of the particularity of nano-glass material surface stress and implosion stress, so that the glass outer anticollision and resistance to compression； And glass outer is that thick middle thin edge has optically focused and amplification effect, the effect for indicating the font shown and hour hands is more It is clear.

Detailed description of the invention

Fig. 1 is the cross-sectional view of the utility model embodiment metal shell glass outer.

Specific embodiment

To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with specific embodiment, the utility model is further described.

Glass outer 100 is the protective cover being arranged in outside metal shell, and Fig. 1 is the utility model embodiment metal shell glass The cross-sectional view of glass outer cover 100.It is described according to structure of the Fig. 1 to glass outer 100:

The flat glass using nano-glass material of the present embodiment forms glass outer 100 by finishing, because of nanometer The particularity of glass material surface stress and implosion stress, so that the glass watchcase anticollision and resistance to compression.

Referring to Fig. 1, the bottom 10 of the glass outer 100 of the present embodiment is concave shaped, the face 20 of glass outer 100 is Spirogyrate.Further, as shown in Figure 1, the cutting plane of the glass watchcase of the present embodiment includes first segment 30, second segment 40 and the Three section 50, first segment 30, second segment 40 and third section 50 are sequentially connected, 40 even width of second segment, by far from second segment 40 to 30 width of first segment close to 40 direction of second segment gradually increases, by the third far from second segment 40 to close 40 direction of second segment 50 width of section gradually increase.Then, the glass outer 100 of 100 thick middle thin edge of glass outer, thick middle thin edge has optically focused Effect, while also having the effect of amplification.And the reflectivity of glass outer 100, less than 2%, light transmittance is higher, so that aobvious Existing font and the effect of hour hands instruction are more clear.

Furthermore the first segment 30 and third section 50 of the present embodiment are arc-shaped, bottom 10 include the first arc surface 11, Medial surface 12 and the second arc surface 13, face 20 include third arc surface 21, lateral surface 22 and the 4th arc surface 23, first segment 30 The first arc surface 11, the second arc surface 13 of 50 inside of third section of inside are tangent with the medial surface 12 of second segment 40, and first Third arc surface 21, the 4th arc surface 23 in 50 outside of third section in 30 outside of section are tangent with the lateral surface 22 of second segment 40. Each joint face is tangent, then can form smooth surface, and the image of display is avoided hopping sense occur to influence display effect.

Compared with prior art, the utility model has the following beneficial effects: the glass outer 100 uses nano-glass Material is fabricated, because of the particularity of nano-glass material surface stress and implosion stress, so that 100 anticollision of glass outer And resistance to compression；And glass outer 100 is that thick middle thin edge has optically focused and amplification effect, refers to the font shown and hour hands The effect shown is more clear.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
