Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses an anti-vibration device for a clock movement. With reference to fig. 1, the anti-shock device for a timepiece movement comprises an anti-shock base 1 and a threaded assembly 2.

With reference to fig. 2 and 3, shock-absorbing base 1 is fixed to movement mount 3, and shock-absorbing base 1 is located between timepiece movement 4 and movement mount 3. Four shockproof bases 1 are provided, and the four shockproof bases 1 are respectively positioned at four corners of the movement fixing seat 3. Because the hand fixing shaft of the clock movement 4 has a certain length, a certain gap is left between the movement fixing seat 3 and the clock movement 4; in order to facilitate the installation of the shockproof base 1, two ends of the movement fixing seat 3 are provided with cushion blocks 31 for reducing the gap. The vibration-proof base 1 damps the timepiece movement 4 when the timepiece movement 4 is struck, so that the timepiece movement 4 is less likely to affect the accuracy of the timepiece movement 4 due to impact. The screwing assembly 2 is used to fix the timepiece movement 4 on the shock-absorbing base 1, so that the shock-absorbing base 1 has a shock-absorbing effect on the timepiece movement 4.

Referring to fig. 4, the screw assembly 2 includes a coupling bolt 21 and a lock nut 22. The connecting bolt 21 is fixed at the bottom end of the shockproof base 1, and the locking nut 22 is in threaded connection with the connecting bolt 21. The four corners of timepiece movement 4 are provided with through holes for connecting bolts 21 to pass through. During fixing, the connecting bolt 21 penetrates through a through hole in the clock movement 4, is in threaded connection with the lock nut 22, and locks and fixes the clock movement 4 through the lock nut 22.

In order to make the timepiece movement 4 less susceptible to wear by the locking nut 22, the connecting bolt 21 is sleeved with an abutment washer 23. The contact washer 23 is intended to come into contact with the tip of the timepiece movement 4, and the contact washer 23 is located between the timepiece movement 4 and the lock nut 22 during locking. A cushion 231 is bonded and fixed to one end of the contact pad 23 close to the base 1, and the cushion 231 is preferably made of a composite rubber material. The shock absorbing pad 231 increases the frictional resistance between the clock movement 4 and the abutting gasket 23, so that the connecting bolt 21 is not prone to being skewed when the clock movement 4 is impacted, and the shock absorbing effect of the shock absorbing device is enhanced.

In order to improve the accuracy of the position of the timepiece movement 4 when it is fixed to the vibration-proof base 1, the connecting bolt 21 is externally fitted with a hollow positioning pin 24, and the hollow positioning pin 24 is made of stainless steel. The top end of the shockproof base 1 is fixed with a circular boss, the top end of the boss is provided with an annular open slot so that the boss forms an embedding groove body 25, and one end, close to the shockproof base 1, of the hollow positioning pin 24 is embedded into the embedding groove body 25. When the clock movement 4 is fixed, one end of the hollow positioning pin 24 is embedded into the scarf groove body 25, then the hollow positioning pin 24 is arranged at the through hole of the clock movement 4 in a penetrating mode, the situation that the position of the clock movement 4 is inclined to press the shockproof base 1 is avoided, and the shockproof effect of the shockproof base 1 is improved.

The vibration-proof base 1 includes a bottom plate 11, a top plate 12, and a vibration-proof support 13. The bottom plate 11 and the top plate 12 are metal circular plates with the same diameter, the bottom plate 11 is fixed on the cushion block 31 through a micro countersunk head screw 111, the top plate 12 is used for installing and fixing the connecting bolt 21, and the top plate 12 and the connecting bolt 21 are welded and fixed. The shockproof support is mainly made of alpha GEL GEL materials, and has excellent shock resistance and excellent shockproof performance; the shock mount is located between bottom plate 11 and roof 12, all fixed connection between shock mount and bottom plate 11 and the roof 12. Shockproof strut 13 separates clock movement 4 and movement mount 3 and plays a shock-absorbing role between clock movement 4 and movement mount 3, so that the vibrations of movement mount 3 are difficult to transmit to clock movement 4.

The top end of the shockproof support column 13 is internally provided with a metal sleeve 26, the metal sleeve 26 is fixedly bonded with the shockproof support column 13, and the inner wall of the metal sleeve 26 is provided with an internal thread matched with the connecting bolt 21.

After the connecting bolt 21 is in threaded connection with the metal sleeve 26, the top plate 12 abuts against the top end of the shockproof strut 13, so that the top plate 12 is firmly connected with the shockproof strut 13, and the clock movement 4 is locked and fixed by the bolt assembly 2.

The longitudinal section of the shock-proof strut 13 is conical, the large end of the shock-proof strut 13 is the end close to the bottom plate 11, and the small end of the shock-proof strut 13 is the end close to the top plate 12. The shock-proof support 13 and the bottom plate 11 are fixedly connected by a miniature countersunk head screw 111. The conical shockproof strut 13 increases the stress area between the shockproof strut 13 and the bottom plate 11, so that the shockproof strut 13 can support the clock movement 4 more stably, and the shockproof effect of the shockproof base 1 is further enhanced.
