While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

It is to be understood that the invention is not to be limited to the specific forms thereof which are to be described in the foregoing description, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims. .

The operation and effect of the power-operated switching control apparatus of the present invention constructed as described above will be described below.

First, FIG. 1 applied to the present invention is a perspective view showing a part of a front face portion showing a first embodiment of the power drive switching control device.

2 shows the operating state of the first embodiment of the present invention,

(a) shows a state in which the power drive switching control portion of the first embodiment is fixed so as not to be rotated.

And Fig. 5B shows a state in which the power drive switching control portion of the first embodiment is rotated counterclockwise.

(C) shows a state in which the power drive switching control portion of the first embodiment is rotated clockwise.

3 is a perspective view showing a part of a front portion showing a second embodiment of the power drive switching control device applied to the present invention.

Fig. 4 shows an operating state of the second embodiment of the present invention, as shown in Figs. 4 (a), (b) and (c).

In the first embodiment of the present invention, the stopper 120 is installed and operated at the upper left and right sides. In the second embodiment of the present invention, the stopper 220 is installed at the left and right sides of the upper and lower ends, Since the operational effects of the first and second embodiments of the invention are similar, the operational effects will be described below with reference to the second embodiment.

The difference between the first embodiment and the second embodiment of the present invention is that, in addition to the number of stoppers, the elastic bulb 130 is connected to the power shaft 330 in the first embodiment, The elastic members 230 and 231 are all operated in the same manner except that they are both connected to the stop 220.

The operation and effect of the second embodiment of the present invention in a state where the water hoist is applied to the hoistway as shown in FIG. 5 will be described below.

Of course, as described above, the power-driven switching control device applied to the present invention can be used for powering a winch, a lift, a gate, as well as a large crane or various devices.

4 (a) shows a state in which the power drive switching control portion 200 of the second embodiment is fixed so as not to be rotated.

That is, unless the handle 300 is rotated, the power drive switching control unit 200 is not rotated. Even if the device connected to the driving gear 350 is to be moved, a plurality of locking holes 221 are formed in the tooth groove 211 The power transmission gear 340 and the power shaft 330 are not rotated.

More specifically, since the stopper 220 is formed in the hinge shaft 222 on the power shaft 330, when the stopper 221 is engaged with the toothed groove 211, the power shaft 330 Is not rotated.

6B shows a state in which the power drive switching control portion 200 of the second embodiment is rotated counterclockwise.

That is, when the handle 300 is rotated counterclockwise, the handle shaft 310 provided at the tip of the handle rotates counterclockwise. When the handle shaft 310 rotates in the counterclockwise direction, the stopper teeth 312 and 313 provided at the upper and lower ends rotate counterclockwise. In this process, the stopper teeth 312 and 313 rotate in the counterclockwise direction. One end of the stopper 220 is pivoted to rotate about the hinge shaft 222 to release the stopper 221 from the toothed groove 211.

The power shaft 330 can be rotated in the counterclockwise direction when the pair of latching openings 221 (4 o'clock direction and 10 o'clock direction) provided in one diagonal direction are separated from the toothed grooves 211 as described above .

At this time, a pair of latching openings 221 (at 2 o'clock and 7 o'clock) provided in the other diagonal direction are inserted into the toothed grooves 211, but are crossed while riding over the toothed grooves 211. As a result, And the stopper 220 is returned by the elastic members 230 and 231. As shown in FIG.

Particularly, in one side of the stopper 220 applied to the present invention, when the stopper piece 312 and 313 push the end of the stopper 220, the stopper 221 rotates around the hinge axis 222, Angle " applied to the present invention is set to be a minimum angle of 5 to 5 mm for pushing the end of the stopper 220, 15 degrees.

Therefore, one side of the stopper bush 312 and the one side of the stopper 220 are rotated in a state in which they are in contact with each other.

(C) shows a state in which the power-driven switching control section 200 of the second embodiment is rotated clockwise.

The operation in which the power-driven switching controller 200 is rotated in the clockwise direction is the same as the operation in the counterclockwise direction described above, so a detailed description will be omitted.

The technical idea of the power-driven switching control device of the present invention is that it is possible to repeat the same results in practice. Especially, by implementing the present invention as described above, it is possible to contribute to industrial development by promoting technological development.
