Abstract

A joining mechanism for bottom cover of watch is composed of watch shell, bottom cover matched with watch shell and with a concave flute and a ring slot an bottom of concave flute, elastic element composed of radial elastic pieces in the ring slot and axial elastic pieces close to the bottom of concave flute to make the radial elastic pieces close to upper edge of ring slot, and cover plate with written information carved on it. Said cover plate is combined with said elastic element into a whole and then embedded in said conceve flute. Pressing and turning the cover plate can move the written information to correct position.

Description

Join unit for bottom cover of watch

The present invention relates to a kind of joining unit for bottom cover of watch.

Existing bottom cover of watch can't be adjusted to the tram with the written historical materials rotation when fastening, if the written historical materials rotation is adjusted to the tram, then bottom cover of watch can't fasten really, so that lower the water-proof function of wrist-watch.In No. 296072 " watch bottom cover structure improvement " novel patent case announced in Taiwan, it comprises a shell and ushers to seat, the end face that this shell is usherd to seat is embedded a hyaline test face, and the bottom surface of being usherd to seat by this shell from bottom to top is embedded a machine core structure, and the bottom surface that this shell is usherd to seat is established a dismountable bottom cover of watch in addition; It is characterized in that the bottom surface central authorities of this bottom cover of watch are axially arranged with one and fall into groove, the end periphery of this sunken groove radially is arranged with an annular groove in addition again, fills out in the deep of this annular groove and establishes a packing ring; Should fall into to fill out in the groove and establish a cover plate; The surface of this cover plate is provided with written historical materials, and the bottom outer peripheral edges of this cover plate are provided with a bulge loop, this cover plate is established into interior the establishing into this annular groove and with this packing ring with this bulge loop of this sunken groove conflicted; Tune this cover plate by above-mentioned structure is feasible, making the machine table data on it is the tram.This cover plate that this patent case is disclosed is established in the sunken groove and is established into annular groove with bulge loop, and conflicts with this packing ring, and its process necessity is quite accurate, numerous and diverse, and manufacturing cost is increased.

The object of the present invention is to provide a kind of joining unit for bottom cover of watch, make the written historical materials rotation of bottom cover of watch be adjusted to the tram, increase the attractive in appearance and texture of Watchcase, and promote the wrist-watch sense of worth, fasten bottom cover of watch really to reach waterproof effect simultaneously.

The object of the present invention is achieved like this, promptly provides a kind of and join unit for bottom cover of watch, and it comprises a watchcase, fastens with a bottom, and described bottom is provided with one and falls into groove, and described sunken trench bottom is provided with an annular groove; It also comprises: a flexible member, be provided with several radially shell fragment and several axial shell fragments, when described flexible member embeds described bottom, several radially shell fragment be stuck in the annular groove of described sunken trench bottom, several axial shell fragments then push against described sunken trench bottom and make radially that shell fragment pushes against in the annular groove upper limb; One cover plate, written historical materials is carved with on the surface, and described cover plate and flexible member are combined as a whole and embed the sunken groove of described bottom.

The invention has the advantages that easy to assembly, simple structure, firm is saved manufacturing cost.

Below in conjunction with accompanying drawing, embodiments of the invention are described, wherein:

Fig. 1 is an exploded perspective view of the present invention;

Fig. 2 is a combination perspective elevation of the present invention;

Fig. 3 is a 3-3 line combination cross sectional side view among Fig. 2;

Fig. 4 is an exploded perspective view of the present invention;

Fig. 5 is a combination perspective elevation of the present invention;

Fig. 6 is that first embodiment makes up cross sectional side view along the 6-6 line among Fig. 5;

Fig. 7 is that second embodiment makes up cross sectional side view along the 6-6 line among Fig. 5.

See also shown in Fig. 1,2, the present invention is made up of watchcase 1, bottom 2, flexible member 3 and cover plate 4.This watchcase 1 is provided with screw thread (not indicating) and can fastens with the screw thread (not indicating) of bottom 2, makes watchcase have waterproof effect.This bottom 2 is provided with one and falls into groove 21, and these sunken groove 21 bottoms are provided with an annular groove 22.The outer rim of this flexible member 3 is provided with several radially shell fragment 31 and several axial shell fragments 32.Be carved with written historical materials 41 on the surface of this cover plate 4, this cover plate 4 utilizes welding or bonding mode to be combined into a combination with flexible member 3, and this combination is embedded in the sunken groove 21 of bottom 2.After this flexible member 3 embedded and falls into groove 21, several of its outer rim radially shell fragment 31 were stuck in the annular groove 22 that falls into groove 21 bottoms the combination hook are attached on the bottom 2, and several axial shell fragments 32 then push against the bottom that falls into groove 21 can not become flexible combination.Several axial shell fragments 32 not only can push against the bottom that falls into groove 21, and when making cover plate 4 along clockwise or counter rotation, can not cause cover plate 4 to break away from bottoms 2.

Please consult shown in Figure 3 again, several of flexible member 3 outer rims radially shell fragment 31 are stuck in the annular groove 22 of bottom 2, several axial shell fragments 32 then push against the bottom that falls into groove 21, make simultaneously several radially shell fragment 31 also push against upper limb at annular groove 22, can make cover plate 4 along clockwise or counter rotation.When needing rotation to adjust written historical materials 41,, get final product toward clockwise or counter rotation again as long as after pressing cover plate 4.

Please consult shown in Fig. 4,5, the sunken trench bottom of this bottom 2 is provided with a ring-type rack rails 23 again.This rack rails 23 can become continuous tooth, and the axial shell fragment 32 of flexible member 3 can be slided betwixt, and forms positioning action at the bottom of resting on tooth.

Please consult shown in Figure 6 again, it is the shown in Figure 5 of the present invention first preferable enforcement state, when cover plate 4 along clockwise or when being rotated counterclockwise, axially shell fragment 32 can slide smoothly and get over rack rails 23, and because these axial shell fragment 32 bumps are to the dip plane of another rack rails 23, so can send the sound.

Please consult shown in Figure 7ly again, it is the shown in Figure 5 of the present invention second preferable enforcement state, and sunken groove 21 bottoms of this bottom 2 are provided with a ring-type rack rails 23, and this rack rails 23 forms continuous unidirectional ratchet, is made up of dip plane 231 and vertical wall 232.During cover plate 4 location, the axial shell fragment 32 of flexible member 3 can rest on position at the bottom of the tooth between dip plane 231 and the vertical wall 232.The axial shell fragment 32 of flexible member 3 can only 231 rotations (arrow direction) along the dip plane owing to be subjected to stopping of vertical wall 232.Cover plate 4 when the arrow direction is rotated, is bound to another dip plane 231 after making axial shell fragment 32 move to dip plane 231 ends again, so can send the sound owing to should axial shell fragment 32 clash into to the dip plane 231.
