Specifically, in the present embodiment, a plurality of buckles 131 are provided on the bottom cover 13, and the plurality of buckles 131 are uniformly arranged along the circumferential direction of the bottom cover 13; the inside wall of center 11 is provided with a plurality of latches 111 and sets up, and a plurality of latches 111 evenly set up on the inside wall of center 11 along the circumference of center 11, through the multiple spot connection, guarantee the stability of connecting, and latch 111 can effectually avoid appearing stress concentration's problem with buckle 131 evenly distributed simultaneously, and then guarantees watchcase structure's stability.
Illustratively, in the present embodiment, four buckles 131 are disposed on the bottom cover 13, and four latches 111 are disposed on the middle frame 11. It should be understood that the number of the hooks 131 and the latches 111 is not limited herein, and in other specific embodiments, the number of the hooks 131 and the latches 111 may be set to three, five, six, or the like according to the requirement of the user.
Fig. 6 is a partially enlarged view of fig. 5. Referring to fig. 6, in an alternative exemplary embodiment, the end of the middle frame 11 is provided with a groove 114 for receiving the sealing ring 12, and the edge of the bottom cover 13 is provided with a flange 139 for pressing the sealing ring 12. Specifically, in the present embodiment, a groove 114 for accommodating the sealing ring 12 is provided at the end of the middle frame 11, and a flange 139 for pressing the sealing ring 12 is provided at the edge of the bottom cover 13. In the assembling process, the sealing ring 12 is placed in the groove 114 at the end of the middle frame 11, and in the connecting process, the first inclined surface 132 is matched with the second inclined surface 112 through the clamping of the clamping structure, so that the bottom cover 13 and the middle frame 11 are close to each other, the flange 139 is pressed on the sealing ring 12 arranged in the groove 114, and good sealing performance is guaranteed.
