The panel locking device 1 of the present invention mainly controls industrial equipment, and includes a substantially hexagonal panel 10 in which an inverter, a PCB board, and the like are housed, and a sliding ILS for controlling opening and closing of the panel 10. It consists of 20 pieces.

The panel 10 is formed in a box shape of a cube, and is attached to the front and rear doors 11 and 12 which are symmetrical, and facilitates opening and closing around the center of the doors 11 and 12. The handle 13 is attached. In addition, the handle 13 is attached to the corresponding positions of the left and right doors 11 and 12, respectively, to maintain a vertically parallel state, and the left door 11 is of a type that can be opened only when the right door 12 is opened. The right door 12 is formed on the upper part of the handle 13 and is formed such that the lower side of the handle 13 can be rotated within about 90 ° in the counterclockwise direction on the basis of the fixing part fixed to the panel 10. It is rotary. When the handle 13 is rotated, it can be pulled forward to open the door, and when the door 13 is closed, the door 13 is closed and the handle 13 on the right is rotated clockwise to return to the original position. 12 is locked by the handle 13.

The sliding ILS 20 is fixedly attached to the front surface of the panel 10 near the lower end of the handle 13 and, when locked, prevents the handle 13 from rotating and rotates in the open state. It is a sliding lock configured to. The configuration is formed on the fixed hook 30 attached to the panel and the sliding hook 40 slidably coupled to the fixed hook 30 and formed on the fixed hook 30 and the sliding hook 40 and sliding. It consists of a locking hole 50 for fixing the sliding action of the type hook 40.

The fixed hook 30 is formed by two surfaces 31 and 33 formed in an approximately " L " shape that is fixedly attached to the lower end of the handle 13 of the door 12, as shown in Figs. ), One side is a fixing surface 31 having a plurality of bolt holes 32 formed to fix the panel 10, and the other surface is a standing surface protruding from the front surface of the panel 10. It is formed of 33. In addition, one side of the standing surface 33 is formed with an elliptic sliding hole 35 extending in the vertical direction to be engaged with the sliding hook 40 to operate up and down.

As shown in FIGS. 1 and 2, the sliding hook 40 (Sliding Shaped Hock) is slidably coupled to the standing surface 33 of the fixed hook 30 to be freely movable, and is approximately " L " It is formed in a "shape" and has two faces 41 and 43. An upper surface 41 having a large diameter hole 42 in the center thereof, and a sliding surface sliding in contact with the standing surface 33 of the fixed hook 30 at a right angle with the upper surface 41 in a downward direction ( 43). One side of the sliding surface is provided with two sliding pins 44 that can engage with the sliding holes 35.

On the other hand, when the sliding ILS 20 is in the locked state, the lower end of the handle 13 of the door 12 flows into the hole 42 of the upper side 41. Therefore, in order to open the doors 11 and 12 of the panel 10, the knob 13 must be rotated outward, but the knob 13 is caught by the edge 45 of the hole 42 so that rotation is impossible. have.

The locking hole 50 is for fixing the sliding hook 40 to the fixed hook 30. When the sliding ILS 20 is locked, the locking hole 50 and the standing surface 33 of the fixed hook 30 are fixed. On the sliding surface 43 of the abutting sliding hook 40, a plurality of holes 50, for example, four to six holes, slide with the standing surface 33 at the same number, shape, and position as the standing surface 33. The face 43 is formed to be penetrated.

In addition, the identification tag 51 or the lock 52 is fastened to the locking hole 50 so as to prevent the sliding hook 40 from moving downward.

Hereinafter, the operation of the panel locking device 1 according to the present invention having the above configuration will be described.

The present invention provides a locking device having a fixed hook 30 and a standing surface 33 and a sliding hook 40 in order to provide a locking device having convenience and stability by using two mutually slidable members having an approximately "L" shape. The locking holes 50 formed on the rising surface 33 by relatively moving the locking holes 50 formed on the sliding surfaces 43 of the sliding surfaces 43 and the sliding hooks 40 when the doors 11 and 12 are locked. And lock the dog tag 51 or the lock 52 in position. Thus, when the locking state as described above, the lower end of the handle 13 of the door 12 is introduced into the hole 42 formed in the upper surface 41 of the sliding hook 40, and when the outer side is rotated outward, 42) Since the lower end of the handle 13 is caught by the edge 45 to prevent rotation, opening of the panel 10 doors 11 and 12 is prevented. In addition, in the case of opening the panel door, first, after unlocking the identification tag 51 or the lock 52, the sliding hook 40 is slid downward, and the door 12 knob 13 is rotated outward. We can easily open simply.

Therefore, in order to apply the ILS 120 to the conventional panel 110, the ILS 120 can be used only when both the primary auxiliary lock 121 and the secondary lock 122 are carried. By using the locking device consisting of the fixed hook 30 and the sliding hook 40 can be easily locked to the panel 10 it is possible to simplify the ILS device.

In addition, the lifespan of the electrical panel 110 is generally 10-20 years, and the panel 110 installed before the safety concept of the operator is applied does not have a separate ILS 120 device. The replacement of both the 113 and the hook 114 results in an increase in cost, but with the configuration of the present invention, the conventional panel 110 handle 113 is used as it is, and the fixed hook 30 and the sliding hook 40 are used. The ILS 20 device can be applied to the panel 10 by adding only).

In addition, the conventional ILS 120 has been difficult to identify and discriminate the working panel 110 when the various panels 110 are inferior, but the present invention has a fixed hook 30 and a sliding hook ( 40) It is easy to identify the position and use condition from the position difference, so it is excellent in visibility.

The present invention can secure the convenience and stability of the operator with a simplified ILS function, and also can be installed at a low cost when applying the ILS to the existing panel, and the task manager can easily identify the panel currently in progress when managing the work accidents It is possible to provide a panel locking device that can be prevented in advance.
