General application.
The three position mechanism of early application uses two set drive mechanism and electric control systems, the respectively isolation of controlling organization
With two kinds of on off states of ground connection.In electrical control, a set control system includes, an a set of drive mechanism of driven by motor, a set of
Auxiliary switch, one group of lead limit switch and two control loops closing tap tentaculum control system composition switch.So, one
Three position mechanism will need two motors, two auxiliary switches and four catalysts.New three position mechanism list motor controls system
The appearance of system, makes the structure of mechanism, and electric control loop is simplified, but, two sets control loop and share an auxiliary switch
It it is a difficult problem for single control system.
Therefore, for solving above-mentioned technical problem, single motor-driven three station actuating machine of a kind of innovation of necessary offer
The electrical control auxiliary switch of structure, to overcome described defect of the prior art.
Utility model content
For solving the problems referred to above, the purpose of this utility model is to provide a kind of single motor-driven three station operating mechanism
Electrical control auxiliary switch, its two set output contacts that can control two groups of switches respectively share on a power transmission shaft, export two
Group controls and signal of communication.
For achieving the above object, the technical scheme that this utility model is taked is: a kind of single motor-driven three station actuating machine
The electrical control auxiliary switch of structure, it includes tumbler gear, connects connecting lever, connecting rod, switch connecting lever and auxiliary switch；Its
In, described tumbler gear connects and drives described connection connecting lever, makes connection connecting lever rotate ± 70 °；Described connecting rod one end connects
To connecting connecting lever, the other end connects described switch connecting lever, makes switch connecting lever can rotate ± 45 °；Described switch connecting lever connects and drives
Dynamic described auxiliary switch；Switch substrate and auxiliary switch patch panel it is provided with in described auxiliary switch；Described auxiliary switch wiring
Plate is provided with static contact and long contact；Described switch substrate can and static contact, long contact in electrical contact.
The electrical control auxiliary switch of single motor-driven three station operating mechanism of the present utility model is further arranged to: institute
That states auxiliary switch is respectively arranged at two ends with end plate.
Compared with prior art, this utility model has the advantages that
1, this utility model have employed tumbler gear system, make auxiliary switch output corner the state of positive and negative 45 °, can be very
Good is combined with three station transmissions.
2, this utility model auxiliary switch keeps two kinds of operating states, i.e. one group auxiliary switch transmission when can rotate in contact
When completing on-off action, another group contact keeps original state.
3, auxiliary switch of the present utility model can be combined into the operating contact of multiple progression according to job demand, at most may be used
To combine 32A+32B.
4, this utility model is owing to have employed multistage contact, therefore reduces auxiliary switch installation volume, makes operating mechanism
Can be little with comparison, make mechanism's more miniaturization.

Detailed description of the invention
Referring to shown in Figure of description 1 to accompanying drawing 3, this utility model is a kind of single motor-driven three station operating mechanism
Electrical control auxiliary switch, its by tumbler gear 1, connect connecting lever 2, connecting rod 3, switch connecting lever 4 and auxiliary switch 5 etc. several
Part composition.
Wherein, described tumbler gear 1 connects and drives described connection connecting lever 2, makes connection connecting lever rotate ± 70 °.By setting
Put described tumbler gear 1 and can change the duty of auxiliary switch.
Described connecting rod 3 one end is connected to connect connecting lever 2, and the other end connects described switch connecting lever 4, makes switch connecting lever 4 energy
Rotate ± 45 °.
Described switch connecting lever 4 connects and drives described auxiliary switch 5.
Switch substrate 6 and auxiliary switch patch panel 7 it is provided with in described auxiliary switch 5；On described auxiliary switch patch panel 7
It is provided with static contact 8 and long contact 9；Described switch substrate 6 can and static contact 7, long contact 8 in electrical contact such that it is able to realize opening
The break-make closed.In the present embodiment, described auxiliary switch 5 arranges several switch substrate 6 and auxiliary switch patch panel 7,
Reduce auxiliary switch 5 installation volume, make operating mechanism more miniaturization.
Described auxiliary switch 5 be respectively arranged at two ends with end plate 10.
The operation principle of the electrical control auxiliary switch of single motor-driven three station operating mechanism of the present utility model is as follows:
For purposes of illustration only, three station auxiliary switches are divided into two groups of contact systems of DS, ES.First, the auxiliary switch 5 adjusted is assemblied in
In mechanism.When mechanism is in double points of states of DS, ES, auxiliary switch 5 adjusts to 0 ° of position, and when mechanism, DS system receives on/off switch
During action command, mechanism drives tumbler gear 1, makes the angle that connection connecting lever 2 rotates about 70 °, by connecting rod 3, switch connecting lever 4
Conversion, make auxiliary switch 5 obtain the rotation repeatedly between 0-45 °, the contact DS system of auxiliary switch 5 is led to the most therewith
Disconnected conversion, ES system contact then keeps original state, does not converts.When mechanism's ES system carries out on/off switch process, auxiliary
Helping switch 5 then to bear at 0-repeatedly to rotate between 45 °, ES makees contact break-make conversion, and DS system then hold mode is constant.
Above detailed description of the invention is only the preferred embodiment of this creation, not in order to limit this creation, all in this wound
Any modification, equivalent substitution and improvement etc. done within the spirit made and principle, should be included in this creation protection domain it
In.
