The following description will be given by way of example of the interlock device 20 being disposed on a power distribution cabinet, and it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for those elements.

Referring to fig. 3, an embodiment of the present invention provides a power distribution cabinet, which includes a cabinet body 10 and an interlocking device 20, the structure of the cabinet body 10 may be substantially the same as the cabinet body of the conventional power distribution cabinet, specifically, the cabinet body 10 has an open side, the side has two vertical and opposite sides, each of the two sides is hinged with a cabinet door 11, and the two cabinet doors 11 can jointly close the open side of the cabinet body 10. While the top of the cabinet 10 is provided with a cross beam 12. The interlocking device 20 is arranged on one of the cabinet doors 11.

Referring to fig. 4 in conjunction with fig. 5, the interlock device 20 includes a housing 21, a rotating shaft 22, a first lock pin 23, a first link 24, a second link 25, a second lock pin 26, and a third link 27.

The housing 21 includes a first sidewall 211, a second sidewall 212, and a third sidewall 213 that are perpendicular to each other, wherein the first sidewall 211 is provided with a first through hole (not labeled in the figure), the second sidewall 212 and the third sidewall 213 are provided on the same side of the first sidewall 211 and are connected to each other, the second sidewall 212 is provided with a second through hole (not labeled in the figure), and the third sidewall 213 is provided with a third through hole (not labeled in the figure). In practice, the housing 21 is generally configured as a cubic structure, wherein the first side wall 211, the second side wall 212 and the third side wall 213 are three mutually perpendicular side walls of the cubic structure.

The rotation shaft 22 is disposed at the first through hole of the first sidewall 211 and can rotate on the first sidewall 211. One end of the rotating shaft 22 is located inside the housing 21, and the other end extends out of the housing 21.

The first locking pin 23 has a first end and a second end opposite to each other, and the first locking pin 23 is located in the housing 21 and is disposed corresponding to the second through hole so that the second end of the first locking pin 23 can protrude out of the housing 21. The first lock pin 23 is perpendicular to the rotating shaft 22, and a first end of the first lock pin 23 is connected to the rotating shaft 22 through the first connecting rod 24 and the second connecting rod 25, and all the connecting points are connected in a hinged manner.

The second latch 26 has a third end and a fourth end opposite to each other, and the second latch 26 is located in the housing 21 and is disposed corresponding to the third through hole so that the fourth end of the second latch 26 can extend out of the housing 21. The second lock pin 26 is perpendicular to the rotating shaft 22 and the first lock pin 23, the third end of the second lock pin 26 is connected with the rotating shaft 22 through the third connecting rod 27, and all the connecting points are connected in an articulated manner.

When the interlocking device 20 is installed on one of the cabinet doors 10, the end of the rotating shaft 22 extending out of the housing 21 should be disposed toward the outside so as to operate the rotating shaft 22. A common connection method may be to form outwardly extending mounting portions 214 on opposite sides of the first side wall 211, then to provide mounting holes 215 on the mounting portions 214, and then to detachably fix the interlocking device 20 to the cabinet door 10 by screws. It is, of course, also possible to provide the second side wall 212 and the third side wall 213 with a cover plate (not shown) directly on the end surface away from the first side wall 211, and then weld the cover plate to the cabinet door 10.

The interlocking device 20 is also installed by arranging two lock pins vertically and horizontally, for example, arranging the first lock pin 23 vertically and the second lock pin 26 horizontally, so that a first lock hole (not shown) matched with the first lock pin 23 can be opened on the other door 11, and a second lock hole (not shown) matched with the second lock pin 26 can be opened on the cross beam 12. In this case, the housing 21 can be provided in a cube shape, that is, the interlocking device 20 can be provided at the upper portion of one cabinet door 11 and near the corner of the other cabinet door 11, and the second and

third sidewalls

212 and 213 can be aligned with the edges of the cabinet doors 10.

After the cabinet door 10 is installed, the cabinet door 10 is closed, then the rotating shaft 22 is rotated in one direction, and the first connecting rod 24 and the second connecting rod 25 can drive the first lock pin 23 to move outwards, so that the second end of the first lock pin 23 extends out of the shell 21 from the second through hole and is inserted into the first lock hole; at the same time, the third link 27 drives the second lock pin 26 to move outward, so that the fourth end of the second lock pin 26 extends out of the housing 21 from the third through hole and is inserted into the second locking hole. In this way, the locking device 20 simultaneously locks the two cabinet doors 10. When the cabinet door 10 needs to be opened, the knob 22 is rotated reversely, and the first lock pin 23 and the second lock pin 26 are driven by the corresponding connecting rods to retract into the shell 21, so that the lock holes are pulled out, and the unlocking action is completed.

In the embodiment, through the matching action of the rotating shaft 22, the first lock pin 23, the first connecting rod 24, the second connecting rod 25, the second lock pin 26 and the third connecting rod 27, the cabinet door 11 of the power distribution cabinet can be locked in two directions simultaneously through single-hand single operation; when unlocking, the rotating shaft 22 is rotated reversely, and the unlocking can be realized by one hand. The utility model discloses an aspect has easy operation, convenient to use's advantage, and on the other hand, the security performance is good, can not produce any danger to operating personnel, and on the one hand again, need not to reform transform current switch board, when keeping the limited usage space of switch board, help saving economic cost.

As a further modification, a knob 28 is provided at the end of the rotary shaft 22 protruding out of the housing 21 for rotational operation.

Of course, those skilled in the art should understand that the interlocking device 20 described in the present embodiment can also be disposed at the lower portion of one of the doors 11 and near the corner of the other door 11, and only the positions of the first locking hole and the second locking hole need to be changed accordingly.
