Detailed Description

Referring to fig. 1-5, the detachable watchband connection structure of the watch of the present invention includes a watch case 1, a back cover 2, a movement 3 (movement of digital electronic watch) and a watchband 4, wherein a core cavity 11 is disposed in the middle of the watch case 1, the movement 3 is nested in the core cavity 11, and the back cover 2 is detachably connected to the back of the watch case 1; the end part of the watchband 4 is provided with a bulge part 41, the side edge of the watchcase 1 is provided with a groove 12 with two ends mutually penetrating, and the bulge part 41 is sleeved in the groove 12; the middle position of bellying 41 is equipped with spacing groove 42, and the lateral part of core chamber 11 corresponds spacing groove 42 and is equipped with the groove of stepping down 111, should step down groove 111 bottom and communicate to recess 12, and the lateral part of core 3 corresponds spacing groove 42 and the groove of stepping down 111 and is equipped with spacing fixture block 31, and spacing fixture block 31 is from last to lower in proper order the joint in groove of stepping down 111 and spacing groove 42 to carry out spacingly with watchband 4.

For the convenience of dismouting back cover 2, the utility model discloses a following structure: four top corners of the back of the watch case 1 are respectively provided with a positioning hole 13, the inner side of the back cover 2 is respectively provided with a bolt 21 corresponding to each positioning hole 13, and the bolts 21 are tightly matched (can be pulled out with slight force) and are inserted into the corresponding positioning holes 13, so that the back cover 2 can be detachably connected to the back of the watch case 1. By the design, the rear cover 2 is convenient to disassemble and assemble, so that the watchband 4 is convenient to replace.

The utility model discloses in, the cross-sectional shape looks adaptation of bellying 41 and recess 12, the cross-section is and is close full circle shape, further, and spacing groove 42, the groove of stepping down 111 and spacing fixture block 31's cross-sectional shape also looks adaptation, the cross-section is the rectangle.
