Description

Technical Field

[0001] The utility model relates to the field of watches, in particular to a mechanical movement of watches with good durability. Background Art

[0002] In some field operations, existing electronic watches freeze in harsh environments, such as high altitude areas. Therefore, it is necessary to add another layer of protection and provide a purely mechanical height display method in addition to the electronic method to provide an extra layer of insurance. When existing mechanical watches are used in the field, due to the complex field environment, it is inevitable that water will enter the inside of ordinary mechanical watches. In some special operations, the staff stays for a very long time and cannot repair the watch in time, which can easily cause the internal parts of the watch to be corroded, thereby causing damage to the internal movement of the watch.

[0003] Therefore, it is necessary to provide a new watch mechanical movement with good durability to solve the above-mentioned technical problems. Utility Model Content

[0006] The waterproof plate is provided with four sets of slide grooves in a circumferential direction, and limit rods are slidably arranged inside the slide grooves;

[0007] The inner wall of the watch case is circumferentially provided with four limiting grooves, and the opposite ends of the four limiting rods all penetrate the mounting ring and extend into the limiting grooves.

[0008] In a preferred embodiment, a sealing gasket is provided between the mounting ring and the watch case.

[0009] In a preferred embodiment, the sealing gasket is made of silicone.

[0010] In a preferred embodiment, a rotating plate is provided on one side of the waterproof plate, and four groups of inclined grooves are circumferentially opened on one side of the rotating plate;

[0011] A driving column is fixed on each of the four limit rods, and the four driving columns are respectively located inside the four groups of inclined grooves. A connecting column is movably provided at the center of the waterproof plate, and the connecting column is fixedly connected to the center of the rotating plate.

[0012] In a preferred embodiment, a connecting block is fixed to a side of the rotating plate away from the movement, and a S-shaped groove is provided on the surface of the connecting block.

[0013] In a preferred embodiment, a bar is provided on the watch case, a waterproof ring is fixed to the outside of the watch case, and an O-ring is provided between the waterproof ring and the bar.

[0014] Beneficial effects of the utility model:

[0015] After the movement of the watch is installed inside the case, the staff can place the waterproof plate and the installation ring inside the case, adjust the position of the installation ring, and then use a screwdriver to rotate the connecting block to drive the rotating plate and the waterproof plate to rotate relative to each other, so that the limit rod slides along the slide groove into the limit groove to complete the fixing of the waterproof plate and the installation ring. The operation is simple and convenient. By setting the sealing pad and the waterproof plate, the risk of water entering the movement can be greatly reduced, and its service life and durability can be increased.

[0016] When water enters the case, after removing the back cover of the case, the staff only needs to use a screwdriver to reverse the turning plate to make the limit rod slide out of the limit slot. At this time, the movement can be inspected and repaired to ensure that the user can clean the movement in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 An exploded view of the main structure of a durable watch mechanical movement provided by the utility model; Figure 2 A schematic diagram of the structure of the rotating plate provided by the utility model; Figure 3 A three-dimensional view of the main structure of a watch mechanical movement with good durability provided by the utility model.

[0023] In the specific implementation process, Figure 1-Figure 3 As shown, it includes a watch case 1, a movement 2 is installed inside the watch case 1, a waterproof plate 3 and a mounting ring 7 are arranged on one side of the movement 2, the waterproof plate 3 is fixed on the mounting ring 7, four groups of slide grooves 4 are circumferentially opened on the waterproof plate 3, and a limit rod 5 is slidably arranged inside the slide groove 4. Four limit grooves 6 are circumferentially opened on the inner wall of the watch case 1, and the opposite ends of the four limit rods 5 all penetrate the mounting ring 7 and extend into the limit groove 6. A sealing gasket 8 is arranged between the mounting ring 7 and the watch case 1. The sealing gasket 8 can prevent external water from flowing into the movement 2 along the gap between the mounting ring 7 and the watch case 1. The sealing gasket 8 is made of silicone. The silicone material has certain tension and flexibility, pressure resistance, high temperature resistance, low temperature resistance, stable chemical properties, environmental protection and safety, no odor and other advantages.

[0024] A rotating plate 9 is provided on one side of the waterproof plate 3, and four groups of inclined grooves 10 are circumferentially opened on one side of the rotating plate 9. Driving columns 11 are fixed on the four limit rods 5, and the four driving columns 11 are respectively located inside the four groups of inclined grooves 10. A connecting column 12 is movably provided at the center of the waterproof plate 3, and the connecting column 12 is fixedly connected to the center of the rotating plate 9. A connecting block 13 is fixed on the side of the rotating plate 9 away from the movement 2, and a slotted groove 14 is opened on the surface of the connecting block 13. The slotted groove 14 on the connecting block 13 is used to drive the rotating plate 9 and the waterproof plate 3 to rotate relative to each other. At this time, the groove wall of the inclined groove 10 will exert a force on the driving column 11, thereby driving the limiting rod 5 to slide along the slide groove 5 into the limiting groove 6 to complete the position fixation. The operation is simple and convenient. By arranging the sealing gasket 8 and the waterproof plate 3, the risk of water entering the movement 2 can be greatly reduced, its service life can be improved, and its durability can be increased.

[0025] A bar 15 is provided on the watch case 1, a waterproof ring 16 is fixed to the outside of the watch case 1, an O-ring is provided between the waterproof ring 16 and the bar 15, and a further waterproof treatment is performed on the connection between the bar 15 and the watch case 1 to prevent water from entering the interior of the movement 2 through the gap between the bar 15 and the watch case 1.

[0026] Working principle of the utility model: after the watch movement 2 is installed inside the watch case 1, the staff can place the waterproof plate 3 and the installation ring 7 inside the watch case 1, adjust the position of the installation ring 7 so that the limit rod 5 corresponds to the position of the limit groove 6, and then use a screwdriver to rotate the connecting block 13 to drive the rotating plate 9 and the waterproof plate 3 to rotate relative to each other. At this time, the groove wall of the inclined groove 10 will exert a force on the driving column 11, thereby driving the limit rod 5 to slide along the slide groove 5 into the limit groove 6 to complete the position fixation. The operation is simple and convenient. By setting the sealing gasket 8 and the waterproof plate 3, the risk of water entering the movement 2 can be greatly reduced, and its service life and durability can be increased.

[0027] When water enters the watch case 1 , after removing the back cover of the watch case 1 , the staff only needs to use a screwdriver to reverse the rotating plate 9 to make the limiting rod 5 slide out from the limiting groove 6 , and then the movement 2 can be inspected and repaired.
