As shown in fig. 3 to 10, a specific structure for realizing the technical scheme is that a locking spring fixing lug 123 penetrating through a shell 11 is arranged above a locking part 12, a compression spring 15 is sleeved on the locking spring fixing lug 123, and the compression spring 15 is propped against the outer surface of the shell 11; the locking part 12 is fixed with a locking screw 16, the rotating part 13 is provided with a clamping hook 132 which can be clamped on the locking screw 16, and the clamping hook 132 drives the locking part 12 to move downwards through the locking screw 16 so that the locking bottom lug 121 is inserted into the locking bottom hole 3.
The compression spring 15 always provides upward force to the locking component 12, when the locking component 12 is not subjected to other acting forces, the locking component 12 can be lifted up, so that the locking bottom lugs 121 are separated from the locking bottom holes 3, and the interlocking device 1 is in an unlocking state; when the hook 132 is clamped to the locking screw 16, the hook 132 drives the locking component 12 to move downwards through the locking screw 16, so that the locking bottom ear 121 is inserted into the locking bottom hole 3, and the interlocking device 1 is in a locking state. The hook 132 is clamped on the locking screw 16, further rotation of the connecting rod 14 is prevented, and damage to parts caused by excessive rotation of the connecting rod 14 is effectively prevented.
As shown in fig. 9, the locking screw 16 has a compact thread structure, which effectively improves its tightening ability and service life. As shown in fig. 5, the locking member 12 is provided with a locking screw hole 126 for installing the locking screw 16, and the housing 11 is provided with a locking screw through hole 118 corresponding to the locking screw 16, and the locking screw through hole 118 can facilitate installation of the locking screw 16 and observation of the state of the locking screw 16.
As shown in fig. 3 to 4, the rotating member 13 is provided with a contact surface 131 that contacts the lock screw 16, and the distance from the contact surface 131 to the rotational axis of the rotating member 13 sequentially increases in one rotational direction of the rotating member 13, and the hook 132 is located at the end of the contact surface 131 having the shortest distance from the rotational axis of the rotating member 13. The contact surface 131 functions to assist the up-and-down movement of the locking member 12, and when the locking member 12 is positioned at the lowermost position, the end of the contact surface 131 having the shortest distance from the rotational axis of the rotating member 13 is brought into contact with the locking screw 16, and when the locking member 12 is positioned at the uppermost position, the end of the contact surface 131 having the longest distance from the rotational axis of the rotating member 13 is brought into contact with the locking screw 16. The contact surface 131 serves to assist in lifting the locking member 12 during movement of the locking member 12 from the lowermost position to the uppermost position.
As shown in fig. 6, a specific shape of the contact surface 131 is that the contact surface 131 of the rotating member 13 is formed by sequentially connecting a locking contact plane 134, a transition surface 135 and an unlocking contact plane 136, and a distance between the locking contact plane 134 and the rotation axis of the rotating member 13 is smaller than a distance between the unlocking contact plane 136 and the rotation axis of the rotating member 13. When the locking member 12 is in the uppermost, i.e. unlocked, state, the unlocking contact plane 136 is in contact with the locking screw 16, since the unlocking contact plane 136 is a plane, stability of the contact point of the unlocking contact plane 136 with the locking screw 16 is ensured. Similarly, the locking member 12 is positioned at the lowermost, i.e., locked, position, where the locking contact surface 134 contacts the locking screw 16, because the locking contact surface 134 is a flat surface, stability of the contact point of the locking contact surface 134 with the locking screw 16 is ensured.
To define the uppermost extreme position of the locking member 12, over-rotation of the link 14 is avoided, effectively preventing damage to the parts. As shown in fig. 3 to 4, the middle part of the locking component 12 is provided with a limiting platform 122 extending outwards, the housing 11 is provided with a limiting opening 111, the limiting platform 122 extends out of the housing 11 from the limiting opening 111, and the limiting platform 122 can be in contact with the upper edge 112 of the limiting opening 111. When the limiting platform 122 contacts with the upper edge 112 of the limiting opening 111, the locking part 12 can not move upwards any more, and the connecting rod 14 can not rotate, at this time, since the compression spring 15 also provides an upward force to the locking part 12, the locking part 12 can keep close to the upper edge 112 of the limiting opening 111 without the action of external force.
As shown in fig. 3 to 4, at least one guide hole 113 is provided in the housing 11, the locking member 12 is provided with guide ribs 124 having the same number as the guide holes 113, the extending direction of the guide ribs 124 is the same as the moving direction of the locking member 12, the guide ribs 124 are in one-to-one correspondence with the guide holes 113, and the guide ribs 124 pass through the corresponding guide holes 113 and slide in the guide holes 113. The guide ribs 124 serve as guides for moving the locking member 12 in a predetermined moving direction, and prevent the locking member 12 from being displaced during movement.
As shown in fig. 3 to 4 and fig. 7 to 8, the housing 11 includes a housing main body 114 fixed to the inner surface of the switch cabinet drawer 2 and a locking cap 115 covering the housing main body 114, one surface of the housing main body 114 below the locking member 12 is hollow, a flange 116 turned out outwards is provided on the lower surface of the housing main body 114, and the flange 116 is fixed to the inner surface of the switch cabinet drawer 2.
The side of the housing main body 114 below the locking component 12 is hollow, so that the locking bottom ear 121 directly passes through the switch cabinet drawer 2 to the drawer bottom plate, and the locking bottom ear is simple in matching and convenient to install.
The flange 116 of the housing body 114 is provided with a fixing hole 119, and the flange 116 is fixed to the inner surface of the switch cabinet drawer 2 through the fixing hole 119.

The fixing rivet 18, as shown in fig. 10, is short in size and does not protrude after installation.
As shown in fig. 1 to 2, the link 14 protrudes to the outside of the cabinet drawer 2, and a handle 17 is mounted to the end of the link 14 located at the outside of the cabinet drawer 2. An operator can conveniently drive the connecting rod 14 to rotate through the handle 17.
As shown in fig. 1 to 8, the cross section of the link 14 is square, the rotary member 13 is provided with a square fitting hole 133 to be fitted with the link 14, the housing 11 is provided with a circular through hole 117 through which the link 14 passes, and the inner peripheral surface of the circular through hole 117 is a circumscribed circle of the link 14. Because the section of the connecting rod 14 is square, and the rotating part 13 is provided with a square matching hole 133, the rotating part 13 can be driven to rotate when the connecting rod 14 rotates; while the circular through hole 117 of the housing 11 ensures that the link 14 rotates about the axis without shifting. As shown in fig. 5, the locking member 12 also has a link via 125 through which the link 14 passes.
As shown in fig. 3, when the handle 17 is rotated clockwise, the rotating member 13 rotates in the same direction with the handle 17, the hook 132 is locked to the locking screw 16, the hook 132 drives the locking member 12 to move downward through the locking screw 16, so that the locking bottom ear 121 is inserted into the locking bottom hole 3, the switch cabinet drawer 2 is locked and cannot be pulled out, and the switch 21 is in a connected state. At the same time, the catch 132 catches on the locking screw 16, preventing further rotation of the handle 17, effectively preventing damage to the parts due to over-rotation of the handle 17.
As shown in fig. 4, the handle 17 is then rotated counterclockwise, the link 14 rotates the rotating member 13, the locking member 12 is lifted upward due to the upward action of the compression spring 15 on the locking member 12, and the guide rib 124 of the locking member 12 passes through the guide hole 113 on the locking cap 115, so that the guide rib 124 does not deflect the locking member 12. When the limit platform 122 is attached to the upper edge 112 of the limit opening 111, the handle 17 cannot rotate any more, the locking bottom ear 121 is disengaged from the locking bottom hole 3, the switch cabinet drawer 2 is also unlocked, the switch cabinet drawer 2 can be pulled out, and the switch 21 is just in an off state. At this time, the compression spring 15 is compressed, and the compression spring 15 always provides an upward force to the locking member 12, so that the limit platform 122 of the locking member 12 always keeps a state of being tightly attached to the upper edge 112 of the limit opening 111.
