Abstract
This utility model relates to a mechanical timer, in particular to timer for switch-off of electrical appliances. The core of the timer adopts a balance wheel and a structure of balancing wire. The balance wheel is connected with an escapement lever, which is matched with an escapement wheel fixing on a head wheel by a driven wheel. Besides accurate timing, this timer activates a ringing device by shutoff of the holding brake, enhancing function of the technical program.
Description
Technical field
The utility model relates to a kind of mechanical timer, relates in particular to the timer that electrical equipment breaks power supply.
Background technology
In the existing relevant timer, the timing movement as critical piece regularly, is connected with clockwork spring and timing wheel on the great wheel of movement, timing wheel and retaining brake are connected, and retaining brake is linked with mains switch again.The timer of said structure is less demanding for precision, and its movement does not adopt escapement and pendulum screw structural.But along with the raising of living standards of the people, general electrical equipment is more and more higher to accuracy requirement regularly, and escapement and pendulum screw structural are applied in this type of timer becomes urgent problem.In addition, in above-mentioned mechanical timer, a mechanical type preferably is set, does not see the report of associated documents for this structure in bell mechanism.
Summary of the invention
The purpose of this utility model is to provide a kind of timing accuracy height and is provided with the timer of mechanical type in bell mechanism.
For achieving the above object, the utility model has adopted following technical scheme: a kind of timer, comprise shell and setting timing movement in the enclosure, be connected with clockwork spring and timing wheel on the great wheel of movement, timing wheel and retaining brake are connected, retaining brake is linked with mains switch again, it is characterized in that described timing movement adopts escapement and pendulum wire structure, this escapement and escapement lever are connected, escapement lever with catch driving wheel and be connected, catch driving wheel and be connected by driven pulley assembly and great wheel.
Described retaining brake is provided with nose bar, and this nose bar extends outside the shell, and is connected with the bell device that cries that is fixed on the shell.
The described bell device that cries is made of a cavity and an elastic rod that is buckled on the shell, and the nose bar on elastic rod and the retaining brake is connected.
Owing to adopted technique scheme, the timing of the technical solution of the utility model is very accurate, simultaneously, by the closing motion of retaining brake, drives and is the bell device, has increased the function of technical scheme.
