As this Watchcase, there is hard material by difficult-to-machine materials such as superhard alloy or potteries to form housing main body.And, on the internal face of each foot in Super hard wristtwatch case, the stop hole of spring base is being set by the Discharge Processing Technology of directly carrying out.
In unloading the watchband process, because the operation when unloading spring base or the impact of spring, the fixed orifice periphery of the foot on this Super hard wristtwatch case is easy to generate slight crack or fragmentation, can produce many apparent problems.This is not only by the physical characteristics of the superhard material of easy fragmentation and causes, also by the micro crack that is accompanied by the rotten machined surface layer that electrodischarge machining produces and cause.
Summary of the invention
The purpose of this invention is to provide a kind of Super hard wristtwatch case, it is not to be modified into by simple structure modify to produce slight crack or broken along with the unloading of spring base of supporting watchband in the foot of housing main body.
In the Super hard wristtwatch case of technical solution of the present invention 1, have: the housing main body of superhard material, the foot of paired foot or the shape suitable about relative position is provided with it; The back of the body covers, and is mounted and fixed on the dorsal part of above-mentioned housing main body; And the spring base installing space, be used for watchband is supported between the above-mentioned foot; Above-mentioned back of the body lid is the metal back of the body lid with resistance to impact, and this back of the body is covered on the face relative with housing main body, make near jag ground offering spring base stop hole be arranged at that the above-mentioned back of the body covers about paired tab and the internal face of each foot adapt; The housing main body of above-mentioned superhard material is the housing main body that is provided with the groove of the notch on the internal face of each foot, and this groove of the notch will be carried on the back chimeric being fixed on the face of each tab of lid; The internal face of above-mentioned each tab and above-mentioned each foot is entrenched in the groove of the notch of above-mentioned each foot with becoming a face, thereby will carries on the back the chimeric dorsal part that is fixed on housing main body of lid, and spring base set up and block only between this tab.
The effect of invention:
As mentioned above, Super hard wristtwatch case of the present invention prevents in the foot's generation of housing main body and the slight crack or the fragmentation of accompanying of unloading of spring base by simple structure modify.This structure modify is, the metal back of the body lid with resistance to impact is being set, and this back of the body lid is set on the face relative with housing main body, make close jag offering spring base stop hole about paired tab and the internal face of each foot adapt; Each tab of above-mentioned back of the body lid is mounted and fixed on the internal face of each foot, and the spring base that supports watchband is set up and blocks only between this tab.
Even above-mentioned spring base stop hole is being arranged under the situation of carrying on the back on the tab that covers a side, also be each tab and internal face to be entrenched on the face by the groove of the notch of each foot, thereby make the chimeric dorsal part that is fixed on housing main body of back of the body lid, thus, in appearance design, also can be assembled into Watchcase with common form.

Embodiment
Below, the embodiment to Super hard wristtwatch case of the present invention describes with reference to accompanying drawing.As shown in Figure 1, present embodiment has housing main body 1, the back of the body cover 2 and spring base 3 (only representing 1 among the figure), and it is with spring base 3 support watchbands 4 and be assembled into Watchcase.Housing main body 1 is formed by superhard materials such as wimet, potteries.The back of the body covers 2 and is formed the metal parts that stainless steel etc. has resistance to impact.
Housing main body 1 is based on outside framework 10, the paired 11a of foot, 11b, 12a, 12b about being provided with on the relative position of outside framework 10, has the installing space 13 (general, as in the wrist-watch professional term, to be also referred to as " leg gap (カ Application thigh) ") that is used for watchband 4 is supported on the spring base 3 between the 11a of foot, 11b, 12a, the 12b.The back of the body cover 2 profile and is formed tabular, chimeric outside framework 10 back sides one side that contains the 11a of foot, 11b, 12a, 12b that is fixed on of this profile energy.Spring base 3 is assembled as by volute spring (among the figure not expression) and suppresses support, this volute spring with about protrudent pin 3a, 3b be housed in the inside of sleeve 3c.
To begin to assemble Watchcase from above-mentioned structural portion is basic mode, sets up and blocks inwall one side that metal parts spring base 3, that have resistance to impact only is installed in the 11a of foot, 11b, 12a, 12b.As its concrete example, exemplify Fig. 1～back of the body shown in Figure 3 and cover 2 situation (the 1st embodiment).
In the 1st embodiment, the back of the body cover be provided with on 2 about paired tab 20a, 20b, 21a, 21b.Each tab 20a, 20b, 21a, 21b form from the plate face relative with housing main body 1 and erect with being integral and have and carry on the back the metal parts that covers 2 identical resistances to impact.On these tabs 20a, 20b, 21a, 21b, offering stop hole 22a, 22b, 23a, the 23b of spring base close jag.
On housing main body 1, the groove of the notch 14 (only representing 1 in Fig. 1) that tab 20a, 20b, 21a, 21b are embedded is being set on the internal face of the 11a of foot, 11b, 12a, 12b.The profile of these grooves of the notch 14 forms and can make that each tab 20a, 20b, 21a, 21b and the internal face of the 11a of foot, 11b, 12a, 12b are chimeric to become a face, and forms with the degree of depth and match.These grooves of the notch 14 can be from equidirectional, form 4 simply simultaneously with electrodischarge machining.
With above-mentioned each structural portion, with essential component-assembled such as works, dial plate or outer glaze to housing main body 1, cover 2 and be close on housing main body 1 dorsal part with screw 5a, 5b by through hole 24a, 24b, 25a, 25b, 5c (in Fig. 1, only representing three), will carrying on the back on four positions, and after being tightened on the housing main body 1, be assembled into Super hard wristtwatch case and wrist-watch.
(only represent 1 among the figure) as shown in Figure 2, on this Watchcase, it is chimeric and unexposedly assemble with the internal face of the 11a of foot and be fixed on the face that the back of the body cover 2 tab 20a and the groove of the notch 14, thereby also can be assembled at the outward appearance design aspect and to have common form.
When the watchband 4 of this Watchcase is installed, (only represent a side among the figure) as shown in Figure 3, the protrudent pin 3a of spring base 3 is embedded among the stop hole 22a of tab 20a, spring base 3 is set up and block only between tab 20a.Because this tab 20a makes stainless steel etc. to have the parts of resistance to impact and cover 2 with the back of the body and form one as described above, thereby can not produce slight crack or the fragmentation of unloading the caused tab 20a of impact that accompanies with spring base 3.
Owing to can also be not the stop hole 22a of spring base be arranged on the 11a of foot of housing main body 1, and cover the 11a of foot of 2 tab 20a enhancing housing main body 1 with the back of the body, thereby can prevent generation slight crack or fragmentation on the 11a of foot of housing main body 1.
Technical terms of Shi Yonging and performance are just used for explanation in this manual, to content of the present invention without any qualification.For example, paired foot also comprises the suitable therewith foot of shape about what is called.In addition, even used technical terms or the performance that limits, its purpose neither be thought therefrom and will get rid of with the content of the embodiment equalization of the invention described above.Therefore, in the described scope of the invention of technical scheme, can carry out all changes.
