Description
(1) technical field
The utility model relates to a kind of mechanical timer.
(2) background technology
Along with the raising of people's living standard, timer has entered common people house.Common timer generally is divided into Mainspring type and electronic type, is widely used in when wind-up timer is walked on the normal domestic use electrical equipment such as electric fan, micro-wave oven, and this class timer timekeeping performance is low, timing range is little, and can only finish the single action that opens or closes.On the commercial units such as electronic timer widespread use and industrial electro baking box, chemical reaction kettle, this class timer is to be loaded in the product as accessory mostly, timing accuracy is higher, the control time scope is big, good stability, but the motor that adopts is bigger, therefore the timer volume is bigger, and manufacturing cost is also high.People are in the real work life; through the original idea of the provisional change of regular meeting; temporary transient outage or energising; be subjected to timer-operated electrical work situation to observe; generally can be by the hand switch button being set as normal open or changing time set key up/down state to reach the outage purpose; but when recovering original setting value, need school team's time and setting-up time setting key again, inconvenience is arranged in the operation more.
(3) summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, the utility model provides a kind of volume mechanical timer little, simple in structure, easy to use.
The technical scheme in the invention for solving the technical problem is: a kind of mechanical timer, comprise housing and be arranged on the interior timing element of housing, also be provided with microswitch in the described housing, the sidewall of described housing is provided with a gathering sill, being equipped with one in the described gathering sill can be along the control toggle of described gathering sill slippage, it is the clicking section that described control toggle stretches out the outer end of described housing, an end that is positioned at described housing is a control part, the end face of the shift knob of close described microswitch is provided with first oblique surface of meeting to described shift knob on the described control part, be provided with a locating shaft in the described housing, being equipped with one on the described locating shaft can be around the balance stem of described locating shaft swing, end near described shift knob on the described balance stem is the press section, described press section also can contact with described shift knob between the described shift knob and first oblique surface, the end face of described press section is provided with second oblique surface adaptive with described first oblique surface, is provided with returning device between described balance stem and the described locating shaft.
Further improve, described returning device is a torsion spring, and its returning device can also be spring, can also be other structures, as long as can make balance stem return when timing stops.
Can also be provided with anti-skidding line on the end face of the clicking section of described control toggle, increase people's friction force in use, can effectively avoid skidding, use more convenient.
The utility model in use, to control toggle beats to opening end, first oblique surface of control part of control toggle slides onto under second oblique surface of press section of balance stem, make balance stem swing around locating shaft, and the shift knob of microswitch is touched in the press section on the balance stem, thereby regularly begins.To control toggle beats to shutdown side, slip away second oblique surface of press section of balance stem of first oblique surface of control part of control toggle, and balance stem is swung around locating shaft under the effect of torsion spring, it is restorable, at this moment the press section is away from the shift knob of microswitch, thereby regularly stop, realizing timing function of the present utility model with this.
The beneficial effects of the utility model are: come the balance stem swing of control setting in housing by the control toggle that is arranged on the housing, and the press section on the balance stem can contact with the shift knob of microswitch, thereby but touch switch button and away from shift knob makes microswitch switch in conducting with between disconnecting; The utility model obtains can carry out timing in 24 hours to the accessory power outlet end under the power supply prerequisite at this machine of assurance when disconnecting gear.When the user needs interim the intervention, when timing element is normally walked, needn't reset and proof time, easy to use, applied widely, and simple in structure, rational and compact makes the utility model smaller volume.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
