[0021] Example:

[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] A protective locking device for an industrial control chassis comprises a main body 1, an upper cover 2, a guide positioning pin 3, a lock baffle 4 and a chassis lock 5. A mounting hole 12 is provided on the rear panel of the main body 1, and the chassis lock 5 is arranged inside the mounting hole 12. Two L-shaped guide grooves 11 are provided on the left and right sides of the main body 1 and the contact surface with the upper cover 2. The guide positioning pin 3 is slidably connected with the L-shaped guide groove 11. Two round holes 21 are respectively provided on the left and right sides of the upper cover 2. The guide positioning pin 3 is installed inside the round hole 21. The lock baffle 4 is arranged at the corresponding position of the chassis lock 5 on the inner side of the upper cover 2. When the upper cover 2, the guide positioning pin 3 and the lock baffle 4 are integrally slidably assembled through the L-shaped guide groove 11 on the main body 1, the chassis lock 5 on the rear panel of the main body 1 is locked by the chassis lock 5 lock key, thereby forming front, back, left, right, up and down restrictions on the upper cover 2, and finally realizing the protective locking function.

[0024] The lock baffle 4 is welded and fixed to the inner side of the upper cover plate 2 and to the corresponding position of the chassis lock 5 .
