The drive crank 400 is disposed below the driven crank 300 and transmits rotational force to the driven crank 300 through a connecting rod 500 to be described later.

The driving crank 400 for this purpose is disposed on the front surface of the front panel 120 and is coupled to the driving shaft 710 of the motor 700 protruding forward of the front panel 120.

The driving crank 400 is installed such that the second rotating end 420 of the other side is eccentrically rotatable in the forward and reverse directions with respect to the second connecting end 410 coupled to the driving shaft 710 of the motor 700.

The connecting rod 500 is connected to both the driving crank 400 and the driven crank 300 at both ends thereof and transmits the rotational force transmitted from the driving crank 400 to the driven crank 300.

In particular, the connecting rod 500 may extend in the longitudinal direction so as to smoothly transmit the force due to eccentric rotation of the driving crank 400 and the driven crank 300 to the driven crank 300. To this end, the connecting rod 500 includes first and second connection pins 511 and 512, a rod housing 520, second and third elastic members 531 and 532, a support plate 550, A support member 540 is provided.

A support plate 550 is inserted into the rod housing 520 and second and third elastic members 531 and 532 are installed on both sides of the support plate 550. And a support member 540 is disposed below the third elastic member 532. [

One end of the first connection pin 511 is coupled to the first connection end 310 of the driven crank 300 and the other end of the first connection pin 511 is coupled to the support plate 550 through the second elastic member 531.

The second connection pin 512 is coupled to the support member 540 having one end thereof with the nut and the other end thereof is coupled to the drive crank 400 so that the distance can be adjusted within a certain range of threading.

Accordingly, the connecting rod 500 can perform the buffering action within a certain range by the second and third elastic members 531 and 532 by the eccentric rotation of the driving crank 400.

In the embodiment of the present invention, it is preferable to use coil springs for the second and third elastic members 531 and 532, and different kinds of the second and third elastic members 531 and 532 may be used as needed .

Further, a holder member 900 coupled to the rear end of the follower shaft 200 may further be coupled to the rear end of the blocking bar 10 described above.

Here, the holder member 900 may include a housing 910 and a holder cover 920 as shown in FIG.

The housing 910 is coupled in a state of wrapping around the rear side of the shut-off bar 10 and an insertion port 911 is formed on one side of the housing 910 so that the rear end of the slave shaft 200 is engaged.

The insertion port 911 is inserted in a shape corresponding to the rear end of the driven shaft 200 and can be engaged with the rear end of the driven shaft 200 by a separate fastening member.

In addition, the rear end of the driven shaft 200 may be formed into a tapered groove whose diameter gradually decreases toward the water depth.

As such, the ease of assembly can be provided by using the corresponding tapered shape of the insertion port 911 and the driven shaft 200.

The holder cover 920 is hinged to one side of the housing 910 with respect to the vertical rotation axis 930 and horizontally pivotally opened and closed with respect to the vertical rotation axis 930.

Here, the rear end of the shut-off bar 10 may be fixedly coupled to the inside of the holder cover 920 facing the housing 910.

The holder cover 920 may be detached from the housing 910 by being pivotally opened with respect to the vertical rotating shaft 930 when a force greater than a reference range is transmitted in the axial direction of the driven shaft 200.

To this end, a magnet may be further coupled to the inner surface of the holder cover 920 so as to be attached to the corresponding surface of the housing 910 by a magnetic force.

For example, when the blocking bar 10 is collided with the vehicle in the state of being turned to the closed position, the holder cover 920 is opened from the housing 910 and at the same time, the blocking bar 10 is avoided Can be pivoted.

That is, by applying the rotation opening / closing structure of the holder cover 920 and the housing 910, the blocking bar 10 and the vehicle can be prevented from being damaged.

In addition, one or more buffering rubbers may be further provided on the length of the shut-off bar 10 to absorb impact.

The buffer rubber may be installed at a plurality of predetermined intervals along the longitudinal direction of the shut-off bar (10).

The buffer rubber may surround the center axis of the shut-off bar 10 and may be formed in a ring shape so as to have the same surface as the shut-off bar 10 and the outer circumferential surface.

That is, since the buffer rubber has a certain elasticity, when the shock is applied to the shut-off bar 10, the shock-absorbing rubber is softened so as to buffer vibration and shock transmitted from the shut-off bar 10, It can be prevented that it is easily broken by an external force.

The opening and closing operation of the vehicle circuit breaker having the above-described structure will now be described. When the blocking bar 10 is rotated to the closed position, the driving shaft 710 of the motor 700 is rotated in the forward direction.

At this time, the first connecting end 310 of the driving crank 400 installed on the driving shaft 710 of the motor 700 is rotated in the forward direction and the connecting rod 500 is interlocked with the upper end.

At the same time, the first connecting end 310 of the driven crank 300 connected to the upper end of the connecting rod 500 is rotated in the forward direction to rotate the driven shaft 200 in the forward direction.

In this process, the horizontal rotation axis 311 of the first connection end 310 is moved by a predetermined length. At this time, the connecting rod 500 is contracted or expanded within a certain length range.

At this time, since the connecting rod 500 is buffered in both directions by the second and third elastic members, it is possible to absorb the operating shock between the connecting rod 500 and the driven crank 300.

The connection crank 211 of the driven shaft 200 is rotated in the forward direction to pull the wire 213 upward so that the first elastic member 214 of the balance member 210 is compressed and the wire fixing portion 216 Is raised in the wire inserting tube 212.

At this time, since a force is applied by the first elastic member 214 in a direction opposite to the rotation direction of the blocking bar 10, a certain buffering force acts on the blocking bar 10, The impact that may occur during the rotation process can be partially buffered.

When the shut-off bar 10 completes its rotation to the open position, the connecting crank 211 is positioned vertically to the upper side when the shut-off bar 10 is rotated to the closed side, The blocking bar 10 is positioned vertically to the closed side at the upper position in the rotational position.

Further, the driven crank 300 is positioned such that the driving crank 400 is vertically inclined upward in the reverse rotation direction when positioned.

Conversely, when the blocking bar 10 is to be rotated to the open position, the driving shaft 710 of the motor 700 is rotated in the reverse direction.

At this time, the first connecting end 310 of the driving crank 400 installed on the drive shaft 710 of the motor 700 is rotated in the opposite direction and the connecting rod 500 is interlocked with the lower end.

At the same time, the first connecting end 310 of the driven crank 300 connected to the upper end of the connecting rod 500 rotates in the reverse direction, and rotates the driven shaft 200 in the reverse direction.

In this process, since the second and third elastic members 531 and 532 are contracted and expanded within the predetermined length range of the connecting rod 500 to buffer the two directions, the connecting rod 500 and the driven crank 300 ). ≪ / RTI >

The connection crank 211 of the driven shaft 200 is rotated in the reverse direction to move the wire 213 downward and the wire fixing portion 216 is moved downward by the wire 213, ).

At this time, since the first elastic member 214 acts to set a force in a direction opposite to the rotation direction of the shut-off bar 10, a force for lifting the shut-off bar 10 can be assisted, Can be reduced.

When the shutting bar 10 completes the rotation to the open position, the connecting crank 211 is positioned vertically to the upper side in the closed position, and the driving crank 400 And the shut-off bar 10 is vertically positioned on the closed side in the rotational position.

Further, the driven crank 300 is positioned such that the driving crank 400 is vertically inclined upward in the reverse rotation direction when positioned.

As a result, according to the present invention, the first to third elastic members 214, 531 and 532 for shock buffering are applied to the connecting portion between the connecting rod 500 and the driven crank 300, The impact generated during operation can be mechanically buffered, thereby reducing damage to the power transmitting parts and operating noise.

In addition, by providing a buffer rubber having a certain elasticity on the length of the shut-off bar 10, the shut-off bar 10 can be prevented from being easily broken by an external force.

Although the embodiment of the present invention has been described above, it will be apparent that various modifications may be made without departing from the scope of the present invention.

Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
