Abstract

A rear lid is fastened to the bottom surface of a wrist watch case by screws, and at the periphery of this rear lid, protrusions protruding from its undersurface are formed solidly in a single piece with the watch case. Restriction parts are formed on strap pieces and contacted from outside with the projections so that the rotations of strap pieces are restricted, so that opening and shutting of the rear lid can be made without being obstructed by the restriction parts, which can thus be conducted without removing the strap pieces from the case with no labor and time substantially.

Description

A kind of belt body syndeton

The present invention relates to be with syndeton.

For example, known, a wrist-watch comprises watchcase assembly and watchband, the watchcase assembly has the watchband syndeton that " 12 point " held and " 6 point " held that is arranged on the watchcase assembly, and watchband comprises two belt bodies being made by synthetic resin, on they are pivotally connected partly by the corresponding watchband that is connected to watchcase.In the wrist-watch of some such type, in the connection partly of each belt body, be formed with the ligule restriction partly.Ligule restriction partly moves into the lower surface of the shell base that constitutes watchcase assembly lower surface, thereby the pivot that limits each belt body rotates, and like this, two belt bodies can have the shape of the fan that picture launches, and watchcase and belt body look and look like an integral body.Such belt body is all well matched to your wrist, and when wrist-watch fell, belt body can absorb bump, because the shell base is not directly to hit on the ground, and hits really in restriction partly.

Yet, in this common wrist-watch, because the ligule that is arranged in the belt body connection partly limits the lower surface that partly moves into the shell base, when the shell base opens or closes, for example in order to change battery, when repairing or similar work, opening or closing by the restriction of the ligule of two belt bodies of shell base partly blocked, and just time-consuming problem occurs.Therefore, unless two belt bodies are all discharged from watchcase, otherwise just can not open or close the shell base.

The objective of the invention is to propose a kind of belt body syndeton, the pivot that it can not only limit belt body rotates, and when wrist-watch falls, absorbs bump, and the shell base is opened or closed easily.

In order to reach this purpose, belt body syndeton of the present invention comprises: mould component, and it comprises the shell base that is configured to form its lower surface and outstanding from the shell base lower surface, and is arranged on around the overhang of shell perimeter position; And pivot is connected to the belt body member of mould component rotationally, and it is included in during the pivot rotation, the watchband member is rotated enter overhang, is used to limit the pivotally supported restriction of belt body member partly.

In the present invention, because the overhang outstanding from the lower surface of shell base is arranged on around the position of shell perimeter, and the pivot of belt body member rotates by the rotation of belt body member being entered overhang and being limited, and opening or closing of shell base partly do not blocked in the restriction of belt body member.Therefore, it can not need to discharge the belt body member and open or close the shell base from watchcase under the pivot limited in rotation state of belt body member.Therefore, may not need a lot of work and time to open or close the shell base.In addition, when wrist-watch drops into ground, can absorbing vibration from the overhang that the shell base lower surface is outstanding.
