When someone else needs to remove the watch case 500, the second lead seal assembly must be broken to remove the plug 600 and thus the watch case 500.
It should be noted that the third abutting portion 315 and the fourth abutting portion 316 position the plug 600 along the circumferential direction of the ferrule 300, so that the fifth connection hole 541 is aligned with the sixth positioning hole 631.
In some embodiments, the side of the latch 600 has a convex arc 620, and the arc 620 is disposed toward the body 110, so that when the latch 600 slides through the first mating hole 521 and the second mating hole 317, the arc 620 has a guiding function, thereby correcting the position of the latch 600 and rapidly sliding into the first mating hole 521 and the second mating hole 317.
In some embodiments, the side of the plug 600 has a boss 610, and the boss 610 is disposed toward the body 110, so that the boss 610 abuts against a side of the third abutting portion 315 away from the body 110, thereby preventing the plug 600 from sliding away from the lower port of the second observation hole 510. Meanwhile, the boss 610 abuts against and is connected to the third abutting portion 315, so that the plug 600 is positioned in the axial direction, and the fifth connecting hole 541 is aligned with the sixth positioning hole 631.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
