Description

Technical Field

[0001] This utility model relates to the field of mechanical watch technology, specifically to a mechanical watch movement with a shock-absorbing watch case structure. Background Technology

[0002] As a precision timekeeping device, the stability of a mechanical watch movement is easily affected by external impacts. Traditional watch case structures are typically made of metal (such as brass, steel, or alloys), primarily functioning to provide rigid support for the movement and isolate it from direct contact with the watch case. However, this type of structure has the following technical drawbacks:

[0003] 1. Insufficient shock absorption: The rigidity of the metal case back means it cannot effectively absorb external impact energy (such as drops or vibrations). The impact force is directly transmitted to the inside of the movement, which may cause damage to precision components such as broken balance shaft and misaligned gears.

[0004] 2. Poor connection stability: The watch case and the watch body are mostly fixed by threaded connection. After long-term use, the threaded pair is prone to loosening due to mechanical wear or vibration, which in turn causes the movement to shift or the operation to be incorrect.

[0005] Therefore, we propose a mechanical watch movement with a shock-absorbing breech structure. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a mechanical watch movement with a shock-absorbing breech structure. The shock-absorbing structure is provided on the outer wall of the breech, which improves protection and enhances the stability of the connection between the watch case and the breech, effectively solving the problems in the background technology.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a mechanical watch movement with a shock-absorbing watch case structure, comprising a movement, wherein a watch case structure is installed on the outer wall of the movement, the watch case structure includes a watch case body and an external threaded connecting ring, the external threaded connecting ring being fixed to the upper outer surface of the watch case body, a crown shaft through hole being provided on one side of the watch case body, and a shock-absorbing structure being provided on the outer wall of the watch case structure, the shock-absorbing structure including an annular rubber, a rubber sleeve, a crown shaft through groove, an annular mounting cavity, a coil spring and a limiting shaft, and a limiting hole being provided on the upper outer surface of the watch case body.

[0010] Preferably, the rubber sleeve is fixed to the lower outer surface of the annular rubber.

[0011] Preferably, the limiting shaft is fixed to the lower outer surface of the annular rubber, and the limiting shaft and the limiting hole are inserted into each other.

[0012] Preferably, the annular rubber is located at the upper part of the bladder, the rubber sleeve is fitted on the outer wall of the bladder, the annular mounting cavity is opened inside the annular rubber, and the helical springs are fixed in the annular mounting cavity at equal intervals.

[0013] Preferably, the annular rubber and the rubber sleeve are made of silicone rubber with a Shore hardness of 40-60.

[0014] Preferably, the spring wire diameter of the helical spring is 0.1-0.3 mm, and its free state height is 1.2-1.5 times the height of the annular mounting cavity.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a mechanical watch movement with a shock-absorbing watch case structure, which has the following beneficial effects:

[0017] 1. This mechanical watch movement with a shock-absorbing breech structure effectively absorbs and buffers external impact energy by setting a shock-absorbing structure on the outer wall of the breech structure and utilizing the elastic properties of the annular rubber and rubber sleeve. This prevents vibration from being directly transmitted to the inside of the movement, significantly reducing the risk of damage to precision components such as the balance shaft and gears, and extending the service life of the movement.

[0018] 2. The mechanical watch movement with a shock-absorbing inner tube structure has a coil spring in the shock-absorbing structure that is always in a pre-compressed state after the case and inner tube are connected by threads, providing a continuous elastic reaction force. This can automatically compensate for the gaps caused by vibration or wear of the threaded pair, prevent the connection from loosening, and ensure the stable installation of the movement in the case.

The watch case structure 2 includes a watch body 4 and an external threaded connecting ring 5. The external threaded connecting ring 5 is fixed to the upper outer surface of the watch body 4. A crown shaft through hole 7 is provided on one side of the watch body 4. A shock-absorbing structure 3 is provided on the outer wall of the watch case structure 2. The shock-absorbing structure 3 includes an annular rubber 8, a rubber sleeve 9, a crown shaft through groove 10, an annular mounting cavity 12, a coil spring 13, and a limiting shaft 15. A limiting hole 6 is provided on the upper outer surface of the watch body 4.

[0027] The rubber sleeve 9 is fixed to the lower outer surface of the annular rubber 8; the limiting shaft 15 is fixed to the lower outer surface of the annular rubber 8, and the limiting shaft 15 and the limiting hole 6 are inserted together; the annular rubber 8 is limited to the upper part of the bladder 4, the rubber sleeve 9 is sleeved on the outer wall of the bladder 4, the annular mounting cavity 12 is opened inside the annular rubber 8, and the helical springs 13 are fixed in the annular mounting cavity 12 at equal intervals; the annular rubber 8 and the rubber sleeve 9 are made of silicone rubber with a Shore hardness of 40-60 degrees; the spring wire diameter of the helical springs 13 is 0.1-0.3mm, and its free state height is 1.2-1.5 times the height of the annular mounting cavity 12.

[0028] It should be noted that this utility model is a mechanical watch movement with a shock-absorbing case structure. The movement 1 and case structure 2 described herein are both existing technologies. The case structure 2 is fixed to the outer wall of the movement 1, which is readily known to those skilled in the art and will not be elaborated further. The shock-absorbing structure 3 is installed by fitting it onto the case structure 2, so that the rubber sleeve 9 wraps around the outer wall of the case 4, the annular rubber 8 is positioned at the upper part of the case 4, and the limiting shaft 15 is inserted into the limiting hole 6. After the watch housing structure 2 is connected to the outer shell, the rubber sleeve 9 acts as a shock absorber between the watch housing structure 2 and the shell. The spiral spring 13 is installed so that after the outer shell is threadedly connected to the external threaded connecting ring 5, the annular rubber 8 and the spiral spring 13 are compressed. After the outer shell is connected to the external threaded connecting ring 5, the spiral spring 13 is always in a compressed state. The reaction force of the spiral spring 13 is used to eliminate the looseness after the threaded connection between the outer shell and the external threaded connecting ring 5, providing continuous preload and improving the stability after installation.
