Description

Technical Field

[0001] The utility model relates to the technical field of clocks and watches, in particular to a shockproof clock and watch. Background Art

[0002] A clock is a device used to measure and indicate time. It usually consists of one or more hands (or numbers) and a dial to display the time, including hours, minutes and seconds (if available). Clocks can be divided into many types, such as mechanical clocks, quartz clocks, electronic clocks, and atomic clocks.

[0003] Upon investigation, it was found that the Chinese utility model patent with publication number CN213457658U discloses a shockproof device for a watch movement, which locks and fixes the watch movement on the shockproof base through a screw assembly, so that the shockproof base can play a shockproof effect on the watch movement, and the abutment gasket can make the watch movement less likely to be worn by the locking nut; however, the movement is only shockproofed by the shock-absorbing spring in the shockproof device, and the damping performance of the shock-absorbing spring itself is relatively low. When it is impacted or vibrated, it cannot effectively convert energy into heat energy or other forms of energy dissipation. Therefore, relying solely on the shock-absorbing spring for shock absorption may not provide sufficient damping effect, especially in the case of high-frequency vibration or large impact.

[0004] Therefore, the utility model provides a shockproof timepiece to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be solved

[0009] A fixing seat is symmetrically arranged at one end of the bracket away from the dial, a guide rod is fixedly installed at one end of the fixing seat away from the bracket, a sliding cylinder is mounted on the guide rod, and the end of the sliding cylinder away from the guide rod is screwed into the watch case, fixing frames are symmetrically arranged on the fixing seat and the sliding cylinder, a rotating rod is hinged in the fixing frame, and two adjacent rotating rods are hinged at one end away from the fixing frame, and a shock-absorbing spring is arranged between the rotating rod on the sliding cylinder and the sliding cylinder.

[0010] Preferably, an inner cavity is provided between the sliding cylinder and the guide rod, and a damping mechanism is provided in the inner cavity.

[0015] (III) Beneficial effects

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A fixing seat 4 is symmetrically arranged at one end of the bracket 2 away from the dial 31, a guide rod 41 is fixedly installed at one end of the fixing seat 4 away from the bracket 2, a sliding cylinder 5 is mounted on the guide rod 41, and the end of the sliding cylinder 5 away from the guide rod 41 is screwed into the watch case 1, a fixing frame 42 is symmetrically arranged on the fixing seat 4 and the sliding cylinder 5, a rotating rod 43 is hinged in the fixing frame 42, and two adjacent rotating rods 43 are hinged at one end away from the fixing frame 42, and a shock-absorbing spring 44 is arranged between the rotating rod 43 on the sliding cylinder 5 and the sliding cylinder 5.

[0025] When in use, the bracket 2 is installed by screwing the fixing seat 4 and the sliding cylinder 5 to the inside of the watch case 1. At the same time, the time can be displayed through the dial 31 during the operation of the movement 3. When the watch is subjected to impact and vibration during normal use, the bracket 2 and the movement 3 will vibrate. At this time, the guide rod 41 can slide in the sliding cylinder 5 to drive the rotating rod 43 in the fixing frame 42 to rotate. During the rotation of the rotating rod 43, the shock-absorbing spring 44 can be stretched and compressed, so that the shock-absorbing spring 44 can be used for shock absorption to avoid damage to the movement 3 due to excessive vibration amplitude.

[0026] Furthermore, an inner cavity 51 is provided between the sliding cylinder 5 and the guide rod 41, and the inner cavity 51 is filled with damping fluid. A damping mechanism 52 is provided in the inner cavity 51, and the damping mechanism 52 includes a connecting rod 521 fixedly mounted on the end of the guide rod 41 away from the fixing seat 4, a damping plate 522 fixedly mounted on the end of the connecting rod 521 away from the guide rod 41 and adapted to the inner cavity 51, and a plurality of evenly distributed connecting micropores 523 provided on the damping plate 522; when the guide rod 41 slides back and forth in the sliding cylinder 5, the damping plate 522 can be driven to slide in the inner cavity 51 through the connecting rod 521, and the damping fluid filled in the inner cavity 51 can pass through the damping plate 522 through the connecting micropores 523 and enter the inner cavity 51 on the other side of the damping plate 522, so that the damping plate 522 generates resistance during the sliding process, thereby reducing the amplitude of vibration, thereby ensuring that the bracket 2 and the movement 3 can be effectively damped.

[0027] Furthermore, a sealing rubber ring 411 is mounted on one end of the guide rod 41 away from the fixed seat 4, and an annular groove 53 adapted to the sealing rubber ring 411 is formed at the open end of the sliding cylinder 5; when the guide rod 41 slides along the sliding cylinder 5, the sealing rubber ring 411 and the annular groove 53 can be used for limiting and guiding, thereby preventing the guide rod 41 from sliding too much, and the sealing rubber ring 411 can seal the inner cavity 51, thereby further improving the sealing inside the inner cavity 51.

[0028] Furthermore, the watch case 1 is provided with a protective cover 11 adapted to the dial 31, and the watch case 1 is provided with an observation window 12 corresponding to the pendulum needle 32 at a position below the protective cover 11; the protective cover 11 can protect the dial 31, and the observation window 12 can display the pendulum needle 32, ensuring that the watch can be used normally.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
