When the containing portion 20 is in a closed state, the second end of the locking rod 102 is limited at the locking position 1031. Specifically, the opening of the guide groove 103 faces upward, the moving block 101 is arranged on the lower surface of the containing portion 20 and there is a certain interval between the top of the guide groove 103 and the lower surface of the containing portion 20, the movement of the containing portion 20 drives the moving block 101 to move, the first end of the locking rod 102 is hinged to the inner surface of the rear side wall of the control cabinet base 10, and the second end of the locking rod 102 is provided with a downwardly extending clamping section, the clamping section moves in the guide groove 103 through the opening of the guide groove 103, and the clamping section can be limited at the clamping position 1031, so that the containing portion 20 remains in a closed state.

[0054] like Fig.11 as well as Fig.12 As shown, the opening of the guide groove 103 is upward, and the guide groove 103 includes a first groove section 1032, a second groove section 1033 and a third groove section 1034 which are sequentially connected and arranged. In the direction from the first end of the first groove section 1032 to the second end of the first groove section 1032, the first groove section 1032 first extends a first distance d1 in the direction away from the first end of the locking rod 102, and then extends a second distance d2 in the direction close to the first end of the locking rod 102, and the second distance d2 is smaller than the first distance d1. In the direction from the first end of the second groove section 1033 to the second end of the second groove section 1033, the second groove section 1033 extends in the direction away from the first end of the locking rod 102, and in the direction from the first end of the third groove section 1034 to the third end of the third groove section 1034, the second groove section 1033 extends in the direction away from the first end of the locking rod 102.

[0055] Fig.11 FIG. 2 shows a state diagram of the locking member 100 when the containing portion 20 is in a closed state. Fig.12FIG. 1 shows a state diagram of the locking member 100 when the receiving portion 20 is in an open state; when the receiving portion 20 needs to be switched from the open state to the closed state, the staff needs to operate the receiving portion 20 to move the locking member 100 to the closed state. Fig.11 and Fig.12 When the holding portion 20 needs to be switched from the closed state to the open state, the staff first operates the holding portion 20 to move to the right side. Fig.11 and Fig.12 Move the holding part 20 to the right side of the Fig.11 and Fig.12 Move to the left in.

[0056] Specifically, the first slot section 1032, the second slot section 1033 and the third slot section 1034 form an annular slot. When the clamping section is located at the first end of the first slot section 1032, the containing portion 20 is in an open state. When the containing portion 20 switches from the open state to the closed state, the moving block 101 moves toward Fig.11 and Fig.12 The clamping section moves to the right in the moving block 101, and moves to the left relative to the moving block 101. Since the second end of the third slot section 1034 is higher than the first end of the first slot section 1032, the clamping section will not move to the left through the second end of the third slot section 1034, but will move to the left through the first end of the first slot section 1032. When the clamping section moves to the second end of the first slot section 1032, since the second end of the first slot section 1032 is higher than the first end of the second slot section 1033, the clamping section will fall into the second slot section 1033 due to its own gravity. At the first end, at this time, the locking section is limited at the locking position 1031; when the containing part 20 needs to be switched to the open state, the staff needs to first make the moving block 101 continue to move a small distance to the right, so that the locking section moves from the locking position 1031 to the second end of the second slot section 1033, and then make the moving block 101 move to the left, so that the locking section moves from the second end of the second slot section 1033 to the second end of the third slot section 1034, and then the locking section falls into the first end of the first slot section 1032 due to its own gravity.

[0057] It should be noted that if Fig.12 As shown, the dotted line in the figure shows the moving path of the locking section, and the "first distance d1" and the "second distance d2" both refer to the length along the preset direction a; the second distance d2 is smaller, so that the locking section can quickly enter the locking position 1031.
