As shown in the drawings, the door opening and closing device of the distributor cabinet of the present invention is a component constituting an exterior case, that is, a cabinet 3 for housing a distribution board therein, and is assembled to the door 5 of the cabinet 3 Is installed.

The locking device includes a lock housing 10 coupled to the door 5, an operation portion 20 assembled in the lock housing 10 to be opened and locked, And a latch (30) fixed to the cabinet or released from the cabinet.

The lock housing 10 is a rectangular box-shaped member to be inserted into the door 5, and a receiving groove 11 is formed in the lock housing 10 so that the operating portion 20 is received therein.

The operating portion 20 is hinged to a hinge pin 21 inserted into the hinge hole 23a at one side of the receiving groove 11 and is hinged by a spring 22 provided inside the receiving groove 11 A push button 23 for elastically supporting the latch 30 in an up and down direction in the receiving groove 11 and a pair of latching projections 24a and 24b formed in a groove 11a formed in the bottom of the receiving groove 11, And a lower groove 25a is received in a groove 24b formed at one side of the sliding guide 24 so as not to be moved toward the sliding guide 24, The upper body 23b of the push button 23 is moved toward the receiving groove 11 by moving toward the opposite side of the sliding guide 24 by unlocking the cylindrical key bundle 26 inserted into the hole 25b formed at the upper center, (25) protruding from the right side wall (25) of the sliding button (25) And a cylindrical spring 27 installed between the vertical side wall 11b of the receiving groove 11 and pushing the sliding button 25 toward the sliding guide 24.

The push button 23 is formed with an upper body 23b having a hole 23a in which the hinge pin 21 is inserted and an upper body 23b that covers a part of the receiving groove 11 at an upper end, A lower latch touched portion 23c protruding from a square-shaped hole 11c formed on the bottom surface of the receiving groove 11 and rotating the latch 30 is formed at a lower end with a center of the lower latch touched portion 23a, The side wall of the upper body 23b is formed with a locking groove 23d for receiving a downward locking protrusion 25e formed at the center of the left side wall 25d of the sliding button 25. [

A locking protrusion 12 protruding downward from both sides of the rectangular hole 11c formed in the lower surface of the lock housing 10 and inserted into the closed curve hole 31 of the latch 30, ) Are facing each other.

The latch 30 has a locking part 32 formed on the other side of the closed curve type hole 31 in a long bar shape so as to be caught in the cabinet.

The closed curve type hole 31 is formed on the opposite side of the lock portion 32 and includes a shaft hole 31a into which the shaft locking pawl 12 is inserted and a shaft hole 31a And a rotary shaft hole 31b so as to form the same rotation radial line around the center of the rotary shaft 31a.

5, a key groove 26a is formed in the upper surface of the cylindrical key cluster 26, a circumferential groove 26b is formed in a circumferential direction in the middle, And an eccentric projection 26d which is eccentric from the center is formed on the lower surface of the vertical groove 26c so that a rectangular protrusion 25f formed in the center of one side wall of the hole 25b of the sliding button 25 is inserted. .

The cylindrical key knob 26 is inserted into the hole 25b of the sliding button 25 so that the rectangular knob 26b of the cylindrical key knob 26 is inserted into the hole 25b of the sliding button 25, 25f so that the rectangular projections 25f are located on the circumferential grooves 26b. The eccentric protrusion 26d is positioned in the eccentric projection groove 11d formed at the bottom of the receiving groove 11 of the lock housing 10. [

When the key is inserted into the key groove 26a of the cylindrical key bundle 26 and turned in one direction when the sliding button 25 is operated to unlock the cabinet in the assembled state as described above, The projection 26d rotates to be positioned on the left side of the eccentric projection groove 11d as shown in FIG. 7A. In this state, when the sliding button 25 is pushed to the right, the cylindrical spring 27 is compressed and moved to the right. The downward locking protrusion 25e formed at the center of the left side wall 25d of the sliding button 25 is released from the locking groove 23d of the push button 23 so that the push button 23 is released from the hinge pin 21, that is, in the receiving groove 11, the upper body 23b is protruded. At the same time, the lower latch touch portion 23c of the push button 23 is moved in the closed curve-shaped hole 31 of the latch 30 to rotate the latch 30 about the axis locking pawl 12 to open the cabinet (See Fig. 4).

When the upper body 23b of the push button 23 protruded into the receiving groove 11 is pressed in order to close and lock the cabinet, the lower latch touch portion 23c of the push button 23 is pressed against the latch 30 The latch 30 is rotated about the shaft locking projection 12 to be caught in the cabinet while moving in the closed curve type hole 31. At the same time, the latching groove 22d formed in the side wall of the upper body 23b The downward locking protrusion 25e of the sliding button 25 is inserted and engaged. In order to prevent the sliding button 25 from being operated in this state, when the key is inserted into the key groove 26a and then turned in one direction, the cylindrical key cluster 26 rotates to rotate the eccentric projection 26d, Is positioned on the right side of the eccentric projection groove 11d as shown in FIG. 7B, and is not pushed even if the sliding button 25 is pushed rightward. That is, it is locked.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. And will be included in the described technical idea.
