Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Fig. 1 is a partial sectional view of the structure of a draft beer bottom cap; FIG. 2 is an exploded view of the main components of the watch; the structure of tight beer bottom mainly includes bottom 5 and watchcase 1, the utility model discloses an innovation is providing a simple structure, tears open and adorns the structural design that the operation is all very simple with the dress, and its gas tightness and stability are still very good. In particular the bottom of the watch case 1 is provided with a circular opening for mounting a bottom cover.
Fig. 3 is a partial sectional view of an opening portion of a circular opening for mounting a bottom cover, the edge of the circular opening is provided with two stages of annular grooves, specifically, a first annular groove 11 and a second annular groove 12, the first annular groove 11 and the second annular groove are adjacently arranged 12, and the cross section is trapezoidal. The first annular groove is arranged at the bottom end of the bottom of the watch case, the opening diameter of the first annular groove is larger than that of the second annular groove, and the side wall of the second annular groove is arranged at an inclination angle with the vertical direction, so that the diameter of the opening of the second annular groove from the bottom end of the bottom of the watch case is gradually increased, preferably linearly increased. The inclination angle of the side wall of the second annular groove and the vertical direction is 1.5-3 degrees. Preferably the angle of inclination is 2 degrees. And corner cutting treatment or fillet treatment is carried out on the connecting part of the first annular groove and the second annular groove. The pressing in is convenient.
FIG. 4 is a partial sectional view of a ring-shaped fixing portion of a bottom cover circumferentially provided with a ring-shaped fixing portion matching a circular opening of a wristwatch case, a hemispherical convex portion B being provided outside an upper end portion of the ring-shaped fixing portion, a diameter of the ring-shaped fixing portion at a hemispherical position being slightly larger than a minimum diameter of an opening end portion of a second annular groove, which is a position of connection with the first annular groove; meanwhile, in order to meet the sealing property after the bottom cover and the watchcase are connected, the waterproof effect is realized.
