Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Reference numeral is as follows:
As shown in Figure 1, the draw bail of wrist-watch arbor of the present invention and transmission wheel, comprise the transmission wheel 2 that plastic material is made and the wrist-watch arbor 1 of being made by metal material, wrist-watch arbor 1 is placed through in transmission wheel 2 axle sleeves 21, can relatively move on axis direction therebetween, the interior cross sectional shape of described axle sleeve 21 is circular, and described arbor 1 leading section 11 is right cylinder, this right cylinder and described axle sleeve 21 interference fit with the bar-shaped trough 13 of the yi word pattern that extends along its axis direction.
As shown in Fig. 3,5, described bar-shaped trough 13 is for being arranged on the in-line groove that runs through this end face on arbor 1 front end face 12, the degree of depth of groove is 0.3mm-1.2mm, be preferably 0.8mm, its width is 0.1mm-0.3mm, is preferably 0.13mm, and groove side 14 and this end face of groove are perpendicular, can arrange one on arbor 1 front end face 12 this end face is divided into two-part bar-shaped trough 13, the bar-shaped trough 13 of many mutual flat shapes also can be set.
As shown in Figure 1, when wrist-watch is in state when normally walking, arbor 1 pushes in wristwatch case, arbor 1 leading section 11 is in transmission wheel 2 axle sleeves 21 and breaks away from wringing fit state (being that arbor 1 leading section 11 is placed in the aperture larger part in axle sleeve 21), even rotate the handle of arbor 1 outer end, therefore transmission wheel 2 can not rotate, and at this moment, transmission wheel 2 axle sleeve 21 cross sectional shapes are just round 3 shapes (as the broken circle in Fig. 4 and Fig. 6).
As shown in Fig. 2,4,6, when outwards stirring arbor 1 to adjusting proof time position, the leading section 11 of arbor 1 merges with transmission wheel 2 axle sleeve 21 close-fittings be interlocked (being that arbor 1 leading section 11 is placed in the aperture smaller part in axle sleeve 21), owing to being interference fit therebetween, 21 pairs of arbors of transmission wheel 2 axle sleeve, 1 leading section 11 imposes radial pressure, this radial pressure be parallel to bar-shaped trough 13 with perpendicular to bar-shaped trough 13 directions on arbor 1 leading section 11 is produced displacement deformation different, be described below:
1) on the direction that is parallel to bar-shaped trough 13, due to the rigid structure of arbor 1, therefore, the make progress diameter of transmission wheel 2 axle sleeves 21 of the party is forced to elongate;
2) on the direction perpendicular to bar-shaped trough 13, because bar-shaped trough 13 has certain gap, under the effect of described axle sleeve 21 plastic cement elastic forces, the extruding force that arbor 1 leading section 11 is subject to is larger, thereby the displacement deformation that produces is larger, the gap of bar-shaped trough 13 also narrows down thereupon, so the party upwards draws close relatively by formed each several parts after bar-shaped trough 13 cuttings, makes front end face 12 ovalizes of arbor 1.
Under the acting in conjunction of above-mentioned two situations, coordinate cylindrical interference by prior art to coordinate to become nearly oval 4 shape interference fit of the present invention between arbor 1 and described axle sleeve 21, namely profile connects and coordinates.
It is exactly to adopt the hole axle of non-round odd-shaped cross section to coordinate to come a kind of connecting mode of transmitting torque that so-called profile connects cooperation.Owing to structurally with on technique unique superiority being arranged, again can transmitting large torque in use, so profile connects to be engaged in various mechanical drive and is widely used.
Profile connects cooperation can improve linking intensity greatly, can reduce manufacturing cost simultaneously, simplifies the manufacture craft of axle sleeve 21, improves the cooperation nargin of axle sleeve 21.
If arbor 1 of the present invention is made by elastic metallic material, after the check and correction of minute hand adjusting is at that time completed, when arbor 1 is pushed when entering in wristwatch case normally to walk state, the leading section 11 of arbor 1 is in release conditions owing to losing the radial pressure of axle sleeve 21 to it, at this moment, the bar-shaped trough 13 on it recovers former state, meanwhile, axle sleeve 21 also because losing arbor 1 leading section 11 to its extruding, recovers virgin state under the effect of plastic cement elastic force.
With after transmission wheel 2 axle sleeves 21 coordinate first, if produce deformation set, again coordinate formed profile connection fit structure also can not affect after when the leading section 11 of arbor 1.
