The utility model provides a but quick assembly disassembly's watchband 10, it is convenient for install on wrist-watch main part 20, also is convenient for dismantle by on the wrist-watch main part 20.

As shown in fig. 1 to 7, the watchband 10 capable of being disassembled and assembled quickly of the present invention includes: a main belt 11 and an auxiliary belt 12;

the main belt 11 is provided with a buckling protrusion 1301, and the auxiliary belt 12 is provided with a first buckling hole 1221; or, the main belt 11 is provided with a first fastening hole 1221, and the subsidiary belt 12 is provided with a fastening projection 1301;

when no external force is applied, the diameter of the end of the buckling protrusion 1301 is larger than that of the first buckling hole 1221;

the first end 121 of the subsidiary band 12 is fixed to the main band 11; the second end 122 of the attachment strap 12 is adapted to pass around the ear 22 of the watch body 20 and be detachably connected to the main strap 11 by engaging the first engaging hole 1221 with the engaging protrusion 1301.

The first end 121 and the second end 122 of the attachment 12 are both ends of the attachment 12 in the longitudinal direction.

When the watch band 10 is applied, the second end 122 of the attachment 12 passes through a gap between the watch ear 22 and the main watch body 21, then the second end 122 of the attachment 12 is folded in a direction away from the watch body 20, and by applying an external force, the end of the fastening protrusion 1301 or the first fastening hole 1221 is deformed to a certain extent, so that the end of the fastening protrusion 1301 passes through the first fastening hole 1221 with a relatively small diameter, and the fastening protrusion 1301 is fastened with the first fastening hole 1221 to play a limiting role, thereby completing the connection between the second end 122 of the attachment 12 and the main band 11, and completing the installation of the watch band 10; at this time, the band 10 can be rotated around the ear 22 of the watch body 20, thereby satisfying the wearing requirements of the watch 10.

When the watch band 10 needs to be detached, the fastening protrusion 1301 is pulled out of the first fastening hole 1221 by applying an external pulling force, and the detachment of the watch band 10 is completed.

The utility model discloses a watchband 10, through the cooperation of dismantling between lock joint arch 1301 and first lock joint hole 1221 realization subsidiary 12's second end 122 and main area 11, the installation between subsidiary 12's second end 122 and the main area 11 can be realized through pressing down the lock, and the dismantlement can be realized through dragging hard. When being applied to a watch, the watchband 10 is simple and convenient to disassemble and assemble, can be disassembled and assembled without special tools or professionals, and is convenient for old people and children to disassemble and assemble the watchband 10 by bare hands.

Note that, when the fastening projection 1301 is provided on the target member (the main tape 11 or the subsidiary tape 12), the present embodiment is implemented as follows: the fastening protrusion 1301 is a portion of an intermediate connector, and is connected to the target component through the intermediate connector, so that the fastening protrusion 1301 is disposed on the target component. Of course, in other embodiments, the fastening protrusion 1301 may be a portion integrally formed on the target component.

Further, the first end 121 of the subsidiary band 12 is detachably connected to the main band 11; so configured, the thickness of the subsidiary band 12 may be different from the thickness of the main band 11; the width of the subsidiary belt 12 may be different from the width of the main belt 11.

Specifically, the thickness and width of the attachment 12 may be designed according to the size of the gap between the case 22 and the main watch body 21 in the watch body 20, so as to ensure that the attachment 12 can go around the case 22 and that the band 10 can freely rotate around the case 22 after the band 10 is mounted. The thickness and width of the main band 11 may not be limited by the size of the gap between the ears 22 and the main watch body 21, and the degree of freedom in designing the main band 11 is greater.

Further, the fastening projection 1301 is an elastically deformable projection or the first fastening hole 1221 is an elastically deformable fastening hole so that the attachment/detachment of the attachment strap 12 and the main strap 11 can be achieved by pressing and pulling operations.
