Embodiment

Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe embodiment of the present utility model in detail.

As Fig. 1 and shown in Figure 6, a preferred embodiment for stopwatch of the present utility model, the stopwatch of this embodiment comprises Transparent Parts 1, circle mouth 2, watchcase 3 and bottom 4, circle mouth 2 is fixed on Transparent Parts 1 upper end of watchcase 3, bottom 4 covers the bottom at watchcase 3, constitute the cavity of a sealing, accommodate in this cavity with inner cover 5 and movement 6 and letter disk 7.In the utility model, in order to solve the outward appearance damage problem that coil structures causes circle mouthful and watchcase of tearing open of existing stopwatch, on the end face 31 of the bottom of watchcase 3, be provided with jackscrew threaded hole 32, jackscrew threaded hole 32 is a through hole, jackscrew threaded hole 32 is over against the lower surface of circle mouth 2, jackscrew threaded hole 32 was screwed into jackscrew screw (not shown) at 2 o'clock at dismounting circle mouth, the jackscrew screw will enclose mouth 2 by ejecting in the watchcase 3, the length of jackscrew screw is greater than the length of jackscrew threaded hole 32, when the jackscrew screw is screwed into the jackscrew threaded hole, its top is against on the lower surface of circle mouth 2, will enclose mouth 2 and eject.Jackscrew threaded hole 32 is inserted Water-proof screw 33 when flat.Jackscrew threaded hole 32 can be provided with a plurality of, jackscrew threaded hole 32 is circumferentially uniform along watchcase 3 bottoms, in the present embodiment, jackscrew threaded hole 32 is for there being four, and interval 90 degree are provided with, the lower surface of jackscrew threaded hole 32 alignment circle mouths 2, unload when tearing circle mouthful open and change four long jackscrew screws into behind the short Water-proof screw 33 and screw synchronously, make that circle mouthfuls 2 is stressed evenly slowly to eject, can make circle mouthfuls 2 evenly stressed like this, avoid circle mouthfuls 2 owing to discontinuity causes damage.

In the present embodiment, the circle mouthful 2 seam steel rings 22 that comprise outer ring 21 and be positioned at 21 inside, outer ring, the upper end interference fit of outer ring 21 and seam steel ring 22, the lower end that the lower end of seam steel ring 22 and watchcase 3 seam interference fit, this seam interference fit are meant seam steel ring 22 and watchcase 3 are that seam cooperates and is interference fit.The lower surface 221 of seam steel ring 22 is the lower surface of circle mouth 2, the lower surface 221 of seam steel ring 22 is over against jackscrew threaded hole 32, the jackscrew screw ejected the circle mouth at 2 o'clock, and the lower surface 221 that the top of jackscrew screw withstands on seam steel ring 22 ejects seam steel ring 22 and outer ring 21 together.

In the present embodiment, have favorable waterproof property in order to make stopwatch, bottom 4 covers when the bottom of watchcase 3, and bottom 4 covers jackscrew threaded hole 32, and bottom 4 is fixedlyed connected with watchcase by bottom screw 44.Further, can in jackscrew threaded hole 32, be provided for the Water-proof screw 33 of waterproof, jackscrew threaded hole 32 be sealed, to play the effect of sealing.Further, the lower end of jackscrew threaded hole 32 is provided with counterbore 321, and the tail end of Water-proof screw 33 is housed in the counterbore 321, is provided with waterproof apron 34 between the tail end of the bottom surface of counterbore 321 and Water-proof screw 33, can obtain more excellent waterproof effect like this.In the present embodiment, circle mouth 2 is provided with capillary groove 211 with 3 contacted of watchcases, is provided with O-ring seal 212 in the capillary groove 211, and is concrete, be on 3 contacted of circle mouthfuls 2 outer rings 21 and watchcases, to be provided with capillary groove 211, can obtain the good whole sealing effectiveness like this.

Owing to adopt and will enclose mouthful 2 implicit expression jackscrews that eject by the watchcase bottom by the jackscrew screw and tear coil structures open, can avoid conventional the sled when pressing seam to tear circle open to hinder mating surface and influences presentation quality, jackscrew threaded hole 32 is hidden by bottom, can not form open defect.

And this implicit expression jackscrew is torn coil structures open, integral body is carried out the processing of outline after circle mouth 2 can being assembled with watchcase 3, for example cut and other outward appearance are handled continuously, can not produce level to guarantee its outer surface along the somatotype section of watchcase 3, circle mouth 2.In the present embodiment, circle mouthfuls 2 is an arc rotary surface with the side of watchcase 3, and arc transition does not have step between the die joint rounding off of circle mouthfuls 2 and watchcase 3, watchcase 3 and circle mouth 2, outward appearance seems the geosphere seamless link, this be the existing stopwatch of tearing coil structures open can not realize.

In the present embodiment, further in order to obtain better appearance, on watchcase 3, be useful on first recess 35 of the end of the watchband 8 of accommodating stopwatch, bottom 4 has and first recess, 35 corresponding second recess 41, first recess 35 and second recess 41 surround the host cavity of the end of accommodating watchband 8, bottom 4 is provided with lock with threaded hole 42, lock with threaded hole 42 over against second recess 41, after the end of watchband 8 is put into this host cavity, lock band screw 43 is screwed into lock with threaded hole 42 can realizes fixing watchband 8.It will be appreciated that what first recess 35 and second recess 42 were all symmetrical is provided with two.Can make the overall appearance of stopwatch more mellow and fuller apparent thin like this.

It will be appreciated that all for stopwatch field screw commonly used, just there are difference in Water-proof screw 33, jackscrew screw, lock band screw 43 and bottom screw 44 on specification and size.

In conjunction with the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the present utility model.
