The locking principle of the above embodiment is as follows:
when the drawer 1 is in the separation position, the transverse bolt 3 can be controlled to be inserted into the first radial blind hole 21 of the rotating wheel, so that the rotating wheel 2 and the transmission shaft 14 cannot rotate, and further the longitudinal position of the drawer 1 cannot move, as shown in fig. 9; when the drawer 1 is in the test position, the transverse bolt 3 can be controlled to be inserted into the second radial blind hole 22 of the rotating wheel, so that the rotating wheel 2 and the transmission shaft 14 cannot rotate, and further the longitudinal position of the drawer 1 cannot move, as shown in fig. 10; when the drawer 1 is in the connection position, the insertion of the transverse bolt 3 into the third radial blind hole 23 of the wheel is controlled so as to disable the rotation of the wheel 2 and the transmission shaft 14, and thus disable the longitudinal displacement of the drawer 1, as shown in fig. 11. The transverse bolt can move transversely by the control mode that a remote central controller generates attraction force (overcoming the elasticity of a return spring 31) by electrifying an electromagnet 32 to push the transverse bolt 3 to be inserted into the radial blind hole of the rotating wheel 2; in an emergency situation, the rubber plug 10 can be pulled out, and the pulling rod passes through the operation hole of the drawer front panel and is inserted into the pulling hole 30 of the interlocking block 33, so that the transverse bolt 2 is driven to transversely move, and the transverse bolt 2 is inserted into the radial blind hole of the rotating wheel 2. Further, in the three states, the lock plate 5 can be pushed to move upwards and be embedded into the first notch groove 41, so that the three movable lock holes 60 of the movable lock plate are respectively aligned with the three static lock holes 70 of the static lock plate, and at most three padlocks can be hung for locking, so long as any one of the three padlocks is not unlocked, the locking state cannot be changed, and personnel in various aspects can respectively have a negative operation control right, as shown in fig. 9, 10 and 11.
On the contrary, when the drawer 1 is at the separation position, if it is required to ensure that the longitudinal position of the drawer can be moved in time, the transverse pin 3 can be controlled to disengage from the first radial blind hole 21 of the rotating wheel, so that the rotating wheel 2 and the transmission shaft 14 can be rotated, and the longitudinal position of the drawer 1 can be moved, as shown in fig. 12; when the drawer 1 is in the test position, if it is required to ensure that the longitudinal position of the drawer can move in time, the transverse pin 3 can be controlled to disengage from the second radial blind hole 22 of the rotating wheel, so that the rotating wheel 2 and the transmission shaft 14 can rotate, and the longitudinal position of the drawer 1 can move, as shown in fig. 13; when the drawer 1 is in the connection position, if it is necessary to ensure that the longitudinal position of the drawer can be moved in time, the transverse pin 3 can be controlled to disengage from the third radial blind hole 23 of the rotating wheel, so that the rotating wheel 2 and the transmission shaft 14 can rotate, and the longitudinal position of the drawer can be moved, as shown in fig. 14. The control mode of the transverse bolt can not only be that the remote central controller cuts off the power supply through the electromagnet 32 to lose the attraction force, so that the elastic force of the reset spring 31 pushes the transverse bolt 3 to be separated from the radial blind hole of the rotating wheel 2, but also can pull the rubber plug 10 away in the emergency situation on site, and the deflector rod passes through the operation hole of the drawer front panel 12 and is inserted into the deflector hole 30 of the interlocking block 33, so that the transverse bolt 2 is driven to transversely move, and the transverse bolt 2 is separated from the radial blind hole of the rotating wheel 2.
