Technical Field

[0001] This utility model relates to the field of alarm clocks, and in particular to a mechanical alarm clock. Background Technology

[0002] Existing mechanical alarm clocks include a movement, which contains a striking mechanism. The dial of the movement is usually 12 hours. The hour hand and hour gear rotate once every 12 hours. After each rotation of the hour gear, it engages with the striking gear. At this time, the release lever releases the escapement in the striking mechanism. The hammer in the escapement can swing under the drive of the mainspring and ratchet and strike the bell on the alarm clock.

[0003] The problem with existing technology is that people usually set alarm clocks to ring only once every 24 hours, while mechanical alarm clocks ring once every 12 hours, which is inconvenient to use. Utility Model Content

[0007] As a further improvement to the above technical solution, the second mechanism also includes a first transmission gear and a second transmission gear. The hour hand gear is connected to the first transmission gear and has the same linear velocity. The second transmission gear is coaxially arranged with the first transmission gear and has the same angular velocity.

[0010] As a further improvement to the above technical solution, the timekeeping mechanism includes a timing disc, a release lever, an escapement, a ratchet, and a mainspring. The escapement is equipped with a connecting rod and a striking hammer. The mainspring drives the ratchet to rotate. The release lever has elasticity and is pressed against the timing disc. The release lever is connected to the front part of the connecting rod, and the rear part of the connecting rod is engaged with the ratchet. The timing disc and the alarm gear are equipped with mutually compatible slides and grooves. After the alarm gear rotates one revolution, the slides and grooves engage.

An hour hand 4 is connected to the hour hand gear 2.

[0026] Principle: By setting up a first mechanism 1 and a second mechanism 5, and the hour hand gear 2 is connected to the alarm clock gear 6 with a transmission ratio of n:1, where n>1, the time for the alarm clock gear 6 to rotate one revolution is greater than one hour. Those skilled in the art can set the value of n as needed, and the alarm clock can start at a specific time period.

[0027] In a preferred embodiment, n is 2, and the hour hand 4 completes one revolution in 12 hours. This is suitable for situations requiring a time signal every 24 hours and is applicable to most users.

[0028] Reference Figure 1 In a preferred embodiment, the second movement 5 further includes a first transmission gear 7 and a second transmission gear 8. The hour hand gear 2 is connected to the first transmission gear 7 and has the same linear velocity. The second transmission gear 8 is coaxial with the first transmission gear 7 (the second transmission gear 8 is located behind the first transmission gear 7) and has the same angular velocity. The linear velocity of the first transmission gear 7 is twice that of the second transmission gear 8. The second transmission gear 8 meshes with the alarm clock gear 6.

[0029] In a preferred embodiment, the first movement 1 further includes a pinion 3, and both the clock gear 2 and the first transmission gear 7 mesh with the pinion 3.

[0030] Reference Figure 4In a preferred embodiment, the device further includes an interval ringing control wheel 18, which is connected to the hour hand gear 2 or the alarm clock gear 6.

The pressing blocks 19 are used to press the release rod 10. The effect of this embodiment is that when the hour hand gear 2 rotates once in twelve hours, the interval ringing control wheel and the control part rotate once in seven days, so that the bell does not ring on the two adjacent days of the weekend within the seven days.

[0031] In a preferred embodiment, the timekeeping mechanism includes a timing disc 9, a release lever 10, an escapement 11, a ratchet 12, and a mainspring 13. The escapement is provided with a connecting rod 14 and a striking hammer 15. The mainspring 13 is used to drive the ratchet 12 to rotate. The release lever 10 has elasticity and is pressed by the timing disc 9. The release lever 10 is connected to the front part of the connecting rod 14, and the rear part of the connecting rod 14 is engaged with the ratchet 12. The timing disc 9 and the alarm clock gear 6 are provided with mutually compatible slides 16 and grooves 17. In use, after the alarm clock gear 6 rotates one revolution, the slide 16 engages with the slide groove 17. At this time, the timer dial 9 approaches the alarm clock gear 6, the release lever 10 springs up and disengages from the connecting rod 14, the connecting rod 14 disengages from the ratchet 12, the mainspring 13 drives the ratchet 12 to rotate, the ratchet 12 drives the escapement 11 to swing, and the bell hammer 15 swings.

[0032] In a preferred embodiment, the housing (not shown) further includes a central shaft of the second transmission gear 8 movably connected to the housing. By pulling the central shaft of the second transmission gear 8 outward, the second transmission gear 8 disengages from the alarm clock gear 6.

[0033] Reference Figure 1 In a preferred embodiment, both the central shaft of the second transmission gear 8 and the central shaft of the pinion 3 are equipped with a speed-changing shaft (not shown in the diagram). Speed-changing gears (not shown in the diagram) are mounted on the speed-changing shaft, and a speed-changing lever 20 is also connected to the speed-changing shaft, extending outside the housing. By moving the speed-changing lever 20, the transmission ratio of the alarm clock and the clock can be manually switched. The speed-changing shaft, gears, and lever 20 are existing speed-changing mechanisms and will not be described further here.

[0034] For reference Figure 5In a preferred embodiment, the device further includes a battery and several motors 21, wherein the battery supplies power to the motors 21, and the hour gear 2 is driven by the motors 21; and / or, the ratchet 12 is driven by the motors 21; and / or, it further includes an interval bell control wheel 18, which is driven by the motors 21, and the transmission ratio between the interval bell control wheel 18 and the hour gear 2 is 7:1.

The sound receiver is connected to a controller, and the controller is electrically connected to the motors 21.

[0035] The advantages of this embodiment are: the battery powers the motor 21, and since the clock gear consumes little power, one battery can last a long time. The motor 21 drives the bell mechanism; if the clock is forgotten to be wound, the battery power can power the motor 21 to make up for the lack of power, or save space and weight on the clockwork 13, allowing for pure electric drive. The bell can be turned on and off by voice control; for example, if the alarm clock is far away and you need to stretch, you can simply call out, and the controller will stop the motor 21 from driving the bell mechanism.
