  The present invention is a proportional control mechanism that controls the rotational direction of a motor by means of a multicontact switch and a relay.

  In general, proportional control senses the operating position by means of a potentiometer or encoder and drives the motor through an electronic circuit.

The conventional mechanism for proportional control drives the motor using a complex and advanced technology using a potentiometer, an encoder and the like. Therefore, it is difficult for general people to carry out maintenance inspections.
The present invention is intended to solve this problem by making it easy for ordinary people to perform maintenance inspections by using a proportional control mechanism of simpler principle and structure.

  The present invention is an assembly of switches, and the design of the control mechanism is simple because the indicator part and the passive part are directly interlocked.

  The present invention is mechanically clear and easy to maintain.

Connect the motor and passive unit to be operated. Operate the indication unit only at the required operating angle. The passive unit bi-directionally controls the rotation of the motor via a multi-contact switch and a relay constituted by the movable contact plate and the contact terminal. The passive unit stops the motor via the multicontact switch and the relay when it comes to a position according to the operating angle of the instruction unit. Therefore, it is controlled proportionally.
Since the distance between the individual terminals of the contact terminals of the indication unit and the passive unit can be designed separately, both operating angles can be set arbitrarily.

Next, an embodiment will be described according to the attached drawings.
4 and 5 are block diagrams of the instruction unit, and mounting brackets 4 and 13. FIG. Stationary bases 5 and 11 with contact terminals 6 and 12 attached. It comprises a movable base 9 having movable contact plates 7 and 8 mounted on both sides. The movable contact plates 7 and 8 are mounted apart from the center of the movable base 9 by the width between the terminals. The movable base 9 is movable with 10 as a fulcrum.

  7 and 8 are structural views of the passive unit, and mounting brackets 14 and 23. FIG. Stationary bases 15, 21 with contact terminals 16, 22 attached. It comprises a movable base 19 to which movable contact plates 17 and 18 are attached. The movable contact plates 17 and 18 have a width between the terminals. The movable base 19 is movable with 20 as a fulcrum.

  As shown in FIG. 8, the contact terminals 6, 12, 16 and 22 attached to the stationary bases 5/11 15 and 21 have winding springs inserted to increase the contact pressure to the movable base side, and the contact terminals Is moved to the movable base side.

FIG. 9 is a circuit diagram, in which individual terminals of the same alphabet of the contact terminals of the support unit and the passive unit are connected.
In FIG. 9, the movable contact plate 7 of the indication unit is in contact with the terminal RSTUV. Since the terminals of the same alphabet are respectively connected, the terminal RSTUV of the passive unit is charged. When the movable contact plate 17 of the passive unit contacts the terminal RSTUV, the motor is driven toward the terminal L via the relay 25. When it moves to the position of the terminal Q, it stops at this position because it is not charged.
The movable contact plate 8 of the instruction unit is in contact with the terminal ABCDE. Since terminals of the same alphabet are respectively connected, terminals ABCDE of the passive unit are charged. When the movable contact plate 18 of the passive unit contacts the terminal ABCDE, the motor is driven in the direction of the terminal K via the relay 24. When it moves to the position of the terminal F, it stops at this position because it is not charged.
As explained above, the movable contact plate of the passive unit moves towards the uncharged terminal. The movable contact plates 7 and 8 of the indication unit are separated from the center of the movable base 9 by the width of the distance between the terminals. Therefore, in the left and right contact terminals of the passive unit, the terminals corresponding to the separated width are both uncharged. Therefore, the movable base 19 of the passive unit stops at this non-charged position.
Thus, the passive unit operates proportionally because it moves in an uncharged position by the indication unit.

In this mechanism, since the size and operating angle of the device are determined by the distance between the terminals, miniaturization and fragmentation of the operating angle are possible by arranging the contact terminals in a plurality of rows.
In addition, since the motor is driven via the relay, the power supply of the motor can be separately provided. If the power supply is separate, application to various mechanisms can be expected because the drive power of the motor is not restricted.

  Next, the dustproof and dripproof of this device. By fixing the shaft in the movable base rotation receiving holes 10 and 20 of the indication unit and the passive unit, the movable base can be moved from the outside via the shaft. By moving the movable base from the outside through the shaft, it is easy to make it dustproof and dripproof.
