Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1 is the bottom view that one embodiment according to the present utility model provides.The embodiment includes the shape that is assembled together
At the watchcase 2, watchband 3 and mechanical device 1 of wrist-watch.Mechanical device 1 is used to connect watchcase 2 and watchband 3, and including being located at watchband 3
The shell 11 of end.Shell 11 can be made of metal or other materials.
Fig. 2 further illustrates the appearance of the joint between watchcase 2 and watchband 3.Shell 11 is in shell 11 close to user
The outer surface of wrist offers adjustment hole 112, and is formed with through-hole 111 along the width direction of the watchband 3.
The structure of watchcase 2 shown in Fig. 2 is the ordinary construction of watchcase 2 currently on the market, and does not include special designing.
The both ends of watchcase 2 are respectively set there are two the lug 21 for being used for fixation table band 3, and each lug 21 is equipped with mounting hole on the inside of it
211.In assembly and disassembly watchband 3, through-hole 111 should be aligned with the mounting hole 211 of two lugs 21.
Fig. 3 (a) is the cross-sectional view of mechanical device shown in Fig. 1 when the long axis of cam is parallel to the axial direction of through-hole；Fig. 3
(b) be mechanical device shown in Fig. 1 when the short axle of cam is parallel to the axial direction of through-hole cross-sectional view.Device 1 further includes two
A resiliency urged component 12 and rotary switch 13, these components are axially mounted in the through-hole 111 of shell 11, through-hole 111
Middle part be connected to adjustment hole 112, two resiliency urged parts 12 are separately mounted to the two sides of through-hole 111.Rotary switch 13 is located at
Adjustment hole 112 between two resiliency urged components 12 and is inserted into the two sides of through-hole 111.
Rotary switch 13 includes adjustment section 131 and cam 132, and 131 self-adjusting hole 112 of adjustment section extends outwardly and for making
User adjusts switch 13 from outside；Cam 132 is closely connected or is combined with adjustment section 131.When rotating adjustment section 131, cam
132 will correspondingly rotate identical angle.
Portion 113 is prominent from the inner wall of through-hole 111, for limiting the movement of two resiliency urged components 12.Resiliency urged portion
Part 12 includes the push rod 121 and the elastic component 122 that is mounted between positioning region 113 and push rod 121 against cam 132.Elastic component
122 remain retracted state under the position-limiting action of positioning region 113 and push rod 121, and push rod 121 is kept in contact with cam 132 always,
Further improve the stability of mechanical device 1.When cam 132 rotates, push rod 121 is stretched along the axial direction of through-hole 111
Out or retract in shell 11.
Fluted 1311 are opened up on the end face of the separate cam 132 of adjustment portion 131, user can be by using common
Tool easily passes through groove 1311 and rotates regulating part 131, and cam 132 can correspondingly rotate.Therefore, because cam 132
Radius of curvature variation, length while rotating adjustment portion 131 along the radial direction of cam 132 is also along through-hole 111
Axial direction variation.If the length, two resiliency urged parts 12 stretch out outside shell 11, if length shortens, due to elasticity
The restoring force of element 122, two resiliency urged components 12 are retracted into inside shell 11.
Preferably, the groove 1311 being limited in adjustment portion 131 is parallel to the longest radical length or shortest diameter of cam 132
To length.Therefore, the connection between watchcase 2 and watchband 3 is adjusted convenient for user.
In this embodiment, cam 132 is elliptical cylinder body, and groove 1311 is parallel to the long axis of cam 132.
Therefore, when groove 1311 is parallel to the axial direction of through-hole 111, watchcase 2 and watchband 3 tightly link together；When slot 1311 hangs down
Directly when the axial direction of through-hole 111, watchcase 2 and watchband 3 are completely separated from each other.
In Fig. 4, the step of watchband 3 is installed to watchcase 2, details are as follows: firstly, preparing to be formed in the two of 2 one end of watchcase
Mechanical device 1 between a lug 21, and the through-hole 111 being aligned with the mounting hole 211 of two lugs 21.By using unskilled labor
Tool, user easily can rotate rotary switch 13 by groove 1311 to push two resiliency urged components 12 steadily
Two end faces of shell 11 are stretched out, then two resiliency urged parts 12 are inserted into mounting hole 211 and complete installation process.
Similar to the step of removing watchband 3 from watchcase 2, user only needs via 1311 rotation turn switch of groove
13, so that it may drive two resiliency urged components 12 to be steadily retracted into inside shell 11, and 2 watchband 3 of watchcase is complete at this time
It is separated from each other.Therefore, watchband 3 is taken away to be completed disassembly process.
The sectional view of Fig. 4 further illustrates following situations: when groove 1311 is parallel to the axial direction of through-hole 111, cam
Axial direction of 132 long axis also parallel with through-hole.The distance between positioning region 113 and push rod 121 reach minimum value, elastic component 122
Deformation reach maximum value.Push rod 121 is released through-hole 111 by cam 132, and push rod 121 is inserted into mounting hole 211 with by table
Band 3 is connected to watchcase 2.
When axial direction of the groove 1311 perpendicular to through-hole 111, but the short axle of cam 132 is also parallel with the axis of through-hole 111
To.The distance between positioning region 113 and push rod 121 reach maximum value and the deformation of elastic component 122 reaches minimum value.Elastic component
122 restoring force is retracted into push rod 121 in shell 11.Therefore, watchband 3 is kept completely separate with watchcase 2.
Above disclosed is only a kind of preferred embodiment of the utility model, certainly cannot be practical to limit with this
Novel interest field, those skilled in the art can understand all or part of the processes for realizing the above embodiment, and according to
Equivalent variations made by the utility model claims, still falls within the scope of the utility model.
