That is, unless specifically stated, each feature is only an example in a series of equivalent or similar features.

[0022] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a watch with a multi-layer protective housing of the present utility model includes a watch body 1 and a protective sheet 2. The protective sheet 2 is arranged parallel to the outside of the mirror surface of the watch body 1. A plurality of lugs 8 are installed on the outer circumferential surface of the watch body 1. Positioning grooves 11 are provided on the lugs 8. Positioning posts 5 are provided in the positioning grooves 11. Slots 12 are provided on one side surface of the positioning posts 5. A fixing frame 3 is installed outside the protective sheet 2. A plurality of insertion plates 4 are installed on the outer circumferential surface of the fixing frame 3. One ends of the insertion plates 4 are inserted into the slots 12 and are fixedly connected to the positioning posts 5. An adjusting mechanism for driving the positioning posts 5 to move up and down is installed on the bottom surface of the lugs 8.

[0023] In this embodiment, the adjusting mechanisms each include a sealed bearing 9 and a lead screw 10. Mounting holes penetrating through the lugs 8 are provided on the inner wall surfaces of the positioning grooves 11. The sealed bearings 9 are installed in the mounting holes. Screw holes 7 are provided on the positioning posts 5 opposite to the sealed bearings 9. The lead screws 10 are installed in the inner rings of the sealed bearings 9. One ends of the lead screws 10 are threadedly connected to the screw holes 7. The other ends of the lead screws 10 are flush with the bottom surface of the lugs 8. Cross grooves are provided at the ends of the lead screws 10 away from the positioning posts 5.

[0024] In this embodiment, first pin holes are horizontally provided on the positioning posts 5. Second pin holes are provided on the insertion plates 4 opposite to the first pin holes. A pin 6 is inserted into the opposite first pin hole and second pin hole. One end surface of the pin 6 is flush with the outer side surface of the positioning post 5, and the other end surface is flush with the side surface of the insertion plate 4;

[0025] Wherein, after the bolt is taken out from the first pin hole and the pin hole, the lead screw can be rotated reversely, and the whole positioning column can be retracted into the interior of the positioning groove through the lead screw, so that the watch body can maintain its original style.

[0026] In this embodiment, the protective sheet 2 is made of transparent tempered glass, and an anti-scratch film is pasted on the surface of the protective sheet 2. The anti-scratch film is a transparent anti-scratch film for mobile phones, which reduces the probability of wear of the protective sheet.

[0027] In this embodiment, the fixing frame 3, the insertion plate 4 and the positioning column 5 are all made of metal materials, which increases the firmness.

[0028] In this embodiment, the insertion plates 4 are all arranged in an "L" shape; the cross section of the vertical end of the insertion plate 4 plus the cross section of the positioning column 5 match the cross section of the positioning groove 11, so that the positioning column can retract the insertion plate into the positioning groove with it.

[0029] During installation, the protective sheet can be placed outside the mirror surface of the watch body, and the insertion plate on the fixing frame can be inserted into the slot. After the first pin hole and the second pin hole are opposite to each other, the bolt can be inserted into the first pin hole and the second pin hole, thereby pre-positioning the insertion plate;

[0030] After the above is completed, a screwdriver can be prepared. The screwdriver can drive the lead screw to rotate. The rotation of the lead screw drives the positioning column, so that the positioning column moves downward along the positioning groove. The movement of the positioning column drives the bolt and the insertion plate, and the insertion plate synchronously drives the fixing frame and the protective sheet. As the positioning column moves, a part of the insertion plate and the whole bolt can enter the positioning groove. The slot and the insertion plate can be positioned through the positioning groove to ensure the stability of the installation of the protective sheet. The protective sheet is close to the mirror surface but does not directly contact the mirror surface. When being impacted, the impact force is prevented from directly acting on the mirror surface, and the watch body can be protected by the protective sheet and the anti-scratch film, greatly reducing the probability of damage to the mirror surface.

[0031] On the contrary, when disassembling, the positioning column can be extended upward through the reversely rotated bolt. After the bolt is removed from the positioning groove, the bolt can be ejected by the screwdriver and the insertion plate can be directly removed to complete the disassembly of the protective sheet, making the installation and disassembly more convenient and achievable by ordinary personnel, greatly reducing the complexity of maintenance.

[0032] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
