Abstract
The utility model provides an improved pendulum device. A metal ring is directly injected on a metal pendulum shaft by the pendulum wheel of the pendulum device, and the pendulum wheel is used for replacing a pendulum wheel composed of a plurality of metal pieces comprising the pendulum shaft, a pendulum nail, a pendulum disk and a safety disk which are rigidly connected in the original pendulum device. The pendulum wheel of the pendulum device has large rotating inertia, small attenuating coefficient, simple production process, and low cost.
Description
The utility model relates to a kind of pendulum device of improved clock and watch.
The escapement of the pendulum device of mechanical clock is formed by the metal parts rigid attachment at present, and the attenuation coefficient of the escapement of existing pendulum device is big, complex manufacturing technology, cost height.
Task of the present utility model provides a kind of improved pendulum device, and the escapement relative weight of this pendulum device is light, moment of inertia is big, and attenuation coefficient is little, and manufacture craft is simple.
Task of the present utility model is finished as follows: the escapement of pendulum device is made up of balance staff, pendulum nail, balance and safety disk four parts, its pendulum nail, balance and safety disk is that one-shot forming is directly injection-moulded in the working of plastics on the metal balance staff, embeds becket in the balance.Because the plastics light specific gravity, mass concentration thereby has improved moment of inertia on becket, reduced attenuation coefficient, and manufacture craft is simple, and cost is low.
Further specify below in conjunction with accompanying drawing and embodiment.
Fig. 1 is a sectional view of the present utility model.
Referring to Fig. 1, the escapement of pendulum device is made up of balance staff 1, balance 2, pendulum nail 4 and safety disk 5.Balance 2, pendulum nail 4 and safety disk 5 are that one-shot forming is injection-moulded in the working of plastics on the balance staff 1, becket 3 is that injection moulding is embedded in the balance 2, the escapement of this pendulum device is the escapement that becket 3 is directly injection-moulded in the 1 last moulding of metal balance staff, with the escapement of this injection moulding, replace the escapement that is rigidly connected and forms by balance staff, pendulum nail, balance and a plurality of metalworks of safety disk in the virgin metal pendulum device.
Claims (1)
1, a kind of pendulum device of clock and watch, its escapement is made up of balance staff 1, balance 2, pendulum nail 4 and safety disk 5, it is characterized by: balance 2, pendulum nail 4 and safety disk 5 are that one-shot forming is injection-moulded in the working of plastics on the balance staff 1, also have a becket 3 that embeds when injection moulding in the balance 2.
