    Detailed Description of Preferred Embodiments The present invention will now be described with reference to the accompanying drawings and embodiments, from which its objects, technical designs, and advantages will be apparent. It is understood that the preferred embodiments described herein are intended to illustrate and not limit the present invention.
    Fig. 1 - Fig. 2 show the double-layer watch case 100 in a preferred embodiment of the present invention comprising an inner cover 10, an outer cover 20 and two housing lugs 30. Two symmetrical recessed recessed sections 101 are provided on the edge of the outer bottom of the inner cover 10, as shown in FIG. 4 , The outer cover 20 is wrapped and wrapped on the outer surface of the inner cover 10 and provided with recessed slots 201 corresponding to the positions of the recessed portions 101, as shown in FIG. 6. The housing lugs 30 are provided with first connection portions 301 that fit with the recessed portions 101, and detachably connected to the recessed portions 101 through the first connection portions 301 for fitting with the inner cover 10. The double-layer structure is even harder, and the outer cover can take on a buffer role and provide better water resistance. Since greater importance is attached to the hardness and scratch resistance of the outer surface in the case of large clocks and small clocks, it is preferred in the present invention that the inner cover 10 and the outer cover 20 are made of different materials. More specifically, the outer cover 20 is made of a material with higher hardness and better scratch resistance, and the inner cover 10 is made of a common material. The outer layer 20 can be much thinner than the watch case of the prior art, so that material costs can be saved in the manufacturing process. Furthermore, the inner cover 10 and the outer cover 20 have a simple structure, which enables holistic molding and processing.
    The inner cover 10 and / or the outer cover 20 are made in one piece by means of stamping and / or oil presses.
    Preferably, the inner cover 10 and the outer cover 20 are made in one piece from thin layers by means of punching and / or oil pressing. Since the structures are simple, they can be automatically produced separately
    CH 714 061 A1 to increase processing efficiency, enable mass production and save production costs and labor costs.
    As shown in Figs. 8, the inner cover 10 and the outer cover 20 match each other in shape. It is preferred in this embodiment that the inner cover 10 and the outer cover 20 are both in the form of a disc with a hollowed-out central part. Of course, they can also be in a polygonal shape with a hollowed-out central part, such as a rectangle or a polyhedron. The diameter of the outer cover 20 is slightly larger than the diameter of the inner cover 10, so that the inner cover 10 can be accommodated in the outer cover 20 and fit well with it. The recessed portions 101 match the recessed slots 201 one-to-one. Furthermore, the two recessed sections 101 are arranged symmetrically on the two sides of the inner cover 10 and have an arc shape, and the housing lugs 30 and the mating first connecting sections 301 abut on the recessed sections 101 and fit together therewith.
    Specifically, the two recessed portions 101 correspond to the inner protrusions of the inner cover 10 to form two placement portions 102 for receiving watch case components. The two placement sections 102 are arranged symmetrically on the inner edge of the inner cover 10, have the same height and are both lower than the upper edge of the inner cover 10.
    The recessed sections 101 are preferably connected to the first connecting sections 301 by means of threads. Of course, other types of connection are also permitted. Each of the recessed portions 101 is provided with at least one first screw hole 1101 that is continuous, the first connecting portions 301 being provided with second screw holes 3011 that correspond to the first screw holes 1101 and are not continuous, and wherein screws 40 pass through the first screw holes 1101 are screwed into the second screw holes 3011 to connect and fix the recessed portions 101 and the first connecting portions 301. In this embodiment, each recessed section 101 is provided with two symmetrical first screw holes 1011, and the first connecting section 301 of each housing extension 30 is provided with two second screw holes 3011, which correspond to the two first screw holes 1011. Since the second screw holes 3011 are not through, the screws 40 do not protrude from the outer bottom surface when the screws 40 are screwed from the inside of the inner cover 10 through the first screw holes 1011 into the second screw holes 3011, thereby having good waterproofness.
    Each of the housing lugs 30 is further provided with a second connecting section 302, which is detachably connected to a watch band module, connected to the inner cover 10, and fastened to the outer cover 20 via the second connecting section 302. The second connecting section 302 connects the watch band to the outside. A button device hole 103 is provided on the outer wall of the inner cover 10, and the outer cover 20 is provided with a device hole 202 which mates with the button device hole 103. The button hole 103 takes over the knob or button function.
    In summary, the double-layer watch case described in the present invention includes an inner cover, an outer cover and two housing lugs. Two symmetrical recessed recessed sections are provided on the edge of the outer bottom of the inner cover. The outer cover is wrapped and wrapped on the outer surface of the inner cover and provided with recessed slots that correspond to the positions of the recessed sections. The housing lugs are provided with first connection sections which fit together with the recessed sections and are detachably connected to the recessed sections via the first connection sections for mating with the inner cover. As a result, the present invention can increase the hardness of the watch case and also has the desired waterproofness, and can be used in automatic production to save production cost and labor cost.
    [0026] Of course, the present invention may also have various other embodiments. Various changes and modifications can be made by those skilled in the art without departing from the scope and spirit of the present invention, but these changes and modifications come within the scope of the present invention.
