When an unexpected situation is met and emergency unlocking is needed, the right side of the cabinet body 1, the management side responsible for management or a full-time manager and the like arrive at the site, the door of the cabinet top box 13 is opened by a key, the rear end of the pressure lever 62 is lifted upwards manually, at the moment, the front end of the pressure lever 62 is inclined downwards, pressure is applied to the connecting pipe 63, the connecting pipe 63 drives the pair of unlocking push pipes 64 to displace downwards under the action of overcoming the reaction force of the pair of unlocking push pipe return springs 66, the unlocking presser feet 6421 on the pair of unlocking push pipes 64 descend to press the unlocking lever 46 of the structural system of the electromagnetic lock 4, the unlocking lever 46 drives the unlocking block 45 towards one end of the unlocking block 45, the unlocking block 45 rotates around the unlocking block shaft 451 by a certain angle, and the unlocking block 45 rotates clockwise by a certain angle to release the cooperation with the lock tongue 43, taking the position state shown in fig. 4 as an example. Since the lock tongue 43 loses the control of the unlocking block 45, the lock tongue hook 431 of the lock catch 43 rotates around the lock tongue hook shaft 4311 by a certain angle under the action of the first torsion spring leg 41 of the torsion spring 44, and the lock tongue hook 431 withdraws from the lock tongue hook hole 322 of the lock catch 32, so that the deposit chamber door 30 can be opened. When the operator releases the pressure lever 62, the unlocking push tube 64 is pulled upward by the restoring force of the pair of unlocking push tube return springs 66, so that the unlocking presser 6421 leaves the unlocking lever 46, and the whole emergency lock mechanism 6 no longer acts on the electromagnetic lock 4.
In summary, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the task of the invention, and faithfully honors the technical effects carried by the applicant in the technical effect column above.
