Abstract
The invention relates to a wrist watch, which includes a watchcase, an inner cover, a bottom cover and a crown, as well as a piece of glass, a figure dial and a metal ring that are arranged above the inner cover, and a watch core arranged in an inner cavity of the inner cover, wherein the inner cover is inserted into an inner cavity of the watchcase from the upward side of the watchcase, and is clamped and arranged on a first annular step in the inner cavity of the watchcase; an annular joint portion of the bottom cover is connected with the lower end of the inner cover in screw-threaded fit; and a flange of the bottom cover compresses upwards on the watchcase. The wrist watch has the following benefits: the force bearing form of the watchcase is converted from the radial force to the axial force, the force bearing structure of the watchcase is changed, and the strength required by the watchcase is converted into the inner cover made of metal material, so that the requirement for the thickness of a case wall of the watchcase is reduced; the case wall of the watchcase is made into a thin wall, so that the metal material use cost is lowered; at the same time, the figure dial is mounted from the upward side of the watchcase, thereby being free from influences of the inner diameter of the watchcase, forming a large-sized open surface figure dial, being more elegant and comfort, and facilitating reading of time indications on the figure dial by a user.
Description
Technical field
The present invention relates to a kind of wrist-watch, more particularly, relate to a kind of face thin-walled wrist-watch of opening greatly.
Background technology
Wrist-watch comprises watchcase, inner cover, bottom and crust; And the glass, letter disk and the becket that are arranged on said inner cover top; Be arranged on the movement of said inner cover inner chamber, traditional fit is, earlier sheathedly from the watchcase below goes into inner cover; Again bottom circumferentially is fixed on the watchcase below, inner cover is supported on the bottom.Therefore; Certain radial force is born in watchcase below and bottom fixed connection place; This force way requires the shell wall of watchcase must have certain thickness and intensity, could guarantee watchcase below and firm being connected of bottom, the obvious like this cost that is unfavorable for reducing metal material.Especially to adopting the wrist-watch of precious metal material, thicker watchcase will significantly increase the volume of noble metal, thereby increase the cost of metal material.
Simultaneously, letter disk is from the watchcase fit beneath, thereby the diameter of letter disk receives the limitation of watchcase below diameter and bottom diameter, and the face size of opening is generally less, is unfavorable for that the client reads on the letter disk time and indicates, and also influences the overall appearance of wrist-watch and the comfort level that the client wears.
Summary of the invention

Embodiment
Wrist-watch is by 11 of watchcase 10, inner cover 20, bottom 30 and crust; And the glass 40, letter disk 60 and the becket 50 that are arranged on said inner cover 20 tops; The movement 70 that is arranged on said inner cover 20 inner chambers is assembled, traditional fit as shown in Figure 1, and glass 40 is located at watchcase 10 tops with becket 50; Inner cover 20 is sheathed from watchcase 10 belows goes into watchcase 10 inner chambers, again bottom 30 circumferentially is fixed in watchcase 10 belows.Like this, inner cover 20 places on the bottom 30 with the movement 70 that is located at inner cover 20 inner chambers, and certain radial force is born in watchcase 10 belows and bottom 30 fixed connection places.
The shell wall of watchcase 10 is a radial force among Fig. 1, must have certain thickness and intensity, could guarantee watchcase 10 belows and bottom 30 firm being connected.Simultaneously watchcase 10 below glass 40, letter disk 60 and inner cover 20 further limit the size of letter disk 60 from watchcase 10 fit beneath, are unfavorable for that the client reads the indication of 60 last times of letter disk, also influences the overall appearance of wrist-watch and the comfort level that the client wears.
Existing map 2,3 and 4 specifies embodiment of the present invention, thereby technical characterictic of the present invention, purpose and effect are had more clearly understanding.
As shown in Figure 2; The inner cover 20 of wrist-watch of the present invention watchcase 10 inner chambers of packing into from watchcase 10 tops; Watchcase 10 inner chambers and inner cover 20 outer walls are respectively equipped with first ring-shaped step 12 and second ring-shaped step 23 that cooperatively interacts, and second ring-shaped step 23 of inner cover 20 is against first ring-shaped step 12 of watchcase 10; Bottom 30 is provided with the annular joint portion of cover plate, perpendicular setting and the flange that extends to circumference, and annular joint portion and inner cover 20 lower end screw threads are connected, the said bottom 30 of upwards screwing, and the flange of said bottom 30 upwards compresses said watchcase 10.
Wrist-watch of the present invention; The stress form of watchcase 10 changes axially loaded into by traditional radial force; Changed the force structure of watchcase 10, watchcase 10 required intensity have been transformed on the inner cover 20 of metal material making, reduced requirement watchcase 10 shell thickness; Be made into the watchcase 10 of thin-walled, reduced the cost that metal material uses.
Shown in the partial sectional view of the present invention of Fig. 3 and Fig. 4; In wrist-watch of the present invention, inner cover 20 outer wall lower ends are provided with external thread, and the annular joint portion inwall of bottom 30 is provided with internal thread; The annular joint portion of bottom 30 is set in outside inner cover 20 lower ends, and both are threaded.Watchcase 10 inwall lower ends are provided with the 3rd ring-shaped step 14; The screw screw thread of bottom 30; The flange of bottom 30 cover plates is pressed on the 3rd ring-shaped step 13, between the flange of the 3rd ring-shaped step 13 of watchcase 10 and bottom 30, is provided with O-ring seal, plays the effect of water-tight.
Like Fig. 3 and shown in Figure 4, the watchcase 10 of wrist-watch of the present invention is provided with 11 first through hole 12 that wears crust, and inner cover 20 also is provided with 11 second through hole 21 that wears crust, and 11 of crust wore first through hole 12 and second through hole 21 respectively, played the effect of circumferential location.
Can show that at Fig. 3 and Fig. 4 inner cover 20 inner chambers of wrist-watch of the present invention are provided with Fourth Ring shape step 15, letter disk 60 inner cover 20 inner chambers of packing into from inner cover 20 tops, and be fastened in the Fourth Ring shape step 15; Above letter disk 60, becket 50 and watchcase 10 inner chambers upper end is provided with five rings shape step 16, glass 40 is located on the five rings shape step 16.
It is thus clear that, adopting the mode of wristwatch case 10 radial forces of the present invention, the wall thickness of watchcase 10 significantly reduces; Letter disk 60 assembling from watchcase 10 tops simultaneously can not receive the influence of shell wall, forms letter disk 60 sizes of opening face greatly; More beautiful and comfortable, be convenient to the client and read the indication of 60 last times of letter disk.
Wrist-watch of the present invention, in the process of repair demolition, at first bottom 30 is taken off in rotation; Upwards promote inner cover 20 with special tooling, inner cover 20 upwards promotes becket 50, and becket 50 is released and driven glass 40 disengaging watchcases 10; Take out becket 50 and movement 70 more successively, movement 70 is keeped in repair.
Combine accompanying drawing that embodiments of the invention are described above; But the present invention is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
