[0021] Reference Figure 1-4, a simplified mechanical locking device comprises a door panel 1 and two sets of locking frames 7, both sets of locking frames 7 are installed on the outside of the door panel 1 and have no connection with the door panel 1, the upper end of the door panel 1 is fixedly connected with two sets of mounting frames 6, a rotating shaft 2 is rotatably connected between the two sets of mounting frames 6, and the rotating shaft 2 is connected with the two sets of locking frames 7 through a locking mechanism, a card block 8 is fixedly connected to the upper end of the door panel 1, a door handle 11 is slidably connected to the outer wall of the card block 8, a sliding groove 12 is provided outside the door handle 11, the inner wall of the sliding groove 12 contacts the outer wall of the card block 8, a door handle pressing slider is installed on the outer wall of the sliding groove 12, a fixed groove 10 is provided on the outer wall of the rotating shaft 2, the end of the door handle 11 is slidably connected to the inside of the fixed groove 10, a pin 13 is slidably connected to the outer wall of the door handle pressing slider, the pin 13 is inserted into the inside of the card block 8, and a stabilizing mechanism is installed on the outer wall of the pin 13; the two sets of locking frames 7 are installed on the outer wall of the door frame, and the swing arm 4 is used to press the door panel into the door frame.
[0022] The stabilizing mechanism comprises a spring 14 sleeved on the outer wall of the pin 13 , one end of the spring 14 is fixedly connected to the door handle pressing slide block, and the other end of the spring 14 is fixedly connected to the end of the pin 13 .
[0023] Reference Figure 2 and Figure 4 The locking mechanism includes two groups of locking shafts 9 fixedly connected to the outer wall of the rotating shaft 2. The positions of the two groups of locking shafts 9 are symmetrical to each other. The outer walls of the two groups of locking shafts 9 are respectively in contact with the inner walls of the two groups of locking frames 7. With the help of the above-mentioned locking shafts 9 and the locking frames 7, the rotating shaft 2 can no longer rotate due to the limitation of the door panel 11, so the door panel 1 cannot be rotated to open.
[0024] The inner bottom of the fixing groove 10 is flat, the lower end surface of the door handle 11 is in contact with the inner bottom wall of the fixing groove 10, two sets of fixing seats 3 are fixedly connected to the side wall of the door panel 1 and two sets of fixed bearings 5 are installed, a swing arm 4 is installed between the two sets of fixing seats 3 and the swing arm 4, the outer wall of the swing arm 4 is L-shaped, and the outer walls of the two sets of locking frames 7 are both L-shaped, and the fixing seat 3 is installed on the upper end of the door panel 1 by screws.

At this time, the door panel 1 can rotate freely. When the door panel 1 needs to be locked, the rotating shaft 2 is rotated to a specified angle so that the locking shaft 9 contacts the inner wall of the locking frame 7, and the lower end of the door handle 11 is in the same vertical plane as the fixed groove 10. By pulling out the pin 13 and stretching the spring 14, the pin 13 slides outward, and then the door handle 11 is clamped in the block 8. After that, release your hand, and under the resetting action of the spring 14, the pin 13 is driven to be inserted into the block 8. The lower end surface of the door handle 11 is in a fit with the upper end surface of the fixed groove 10. At this time, the rotating shaft 2 cannot rotate, so the door panel 1 cannot be rotated to open.
