[0002] Drawers are common in life and have a wide range of application scenarios. Hospitals usually use traditional drawer cabinets and a small number of electric drawer cabinets. Traditional drawers are generally opened or closed by manual pushing and pulling. With the development of the times and the improvement of people's living standards, the frequency of using electric drawer cabinets in hospitals for the convenience of material control has gradually increased. This electric drawer cabinet is provided with an electric drawer and a motor, and the motor is used to drive the drawer to open or close. However, the electric drawer in the existing electric drawer cabinet needs to be powered on for use. If the drawer cabinet circuit fails and needs to be repaired, the electric drawer cabinet cannot be powered on for use. At this time, the electric drawer in the traditional electric drawer cabinet is driven by a screw, but the thread on the screw has a self-locking function. After the power is off, the drawer cannot be opened by manual pushing and pulling, and the items in the drawer cannot be taken out. The existing electric drawer cabinet uses an ordinary motor. If multiple motors are used, there is an error in the speed matching between the multiple motors, and one of the motors fails so that its operating frequency is different from that of another motor.

[0039] When the present scheme is implemented, technicians in this field can control the opening and closing of the synchronous motor 3 so that the drawer 2 can be opened or closed electrically. The present scheme adopts a synchronous motor 3, and two synchronous motors 3 are arranged on both sides of the drawer 2. The two synchronous motors 3 can be opened or closed synchronously, and the push-pull drawer 2 is more stable without jamming. Before the motor is activated, technicians in this field need to first adjust the adjustment wheel group 15 to a suitable speed so that the rotation rate of the gear 9 is suitable for the opening and closing of the drawer 2. When the synchronous motor 3 is started, the output shaft 12 can drive the gear 9 to rotate. Since the gear 9 is meshed with the rack 10, one side of the rack 10 is fixedly connected to the drawer 2, thereby opening or closing the drawer 2. In another embodiment, technicians in this field can also set the rack 10 at the convex edge 8 position above the drawer 2. The synchronous motor 3 also drives the gear 9 to rotate and drives the rack 10 and the drawer 2 to move. In the present scheme, when the gear 9 rotates clockwise to open the drawer 2, the gear 9 rotates counterclockwise to close the drawer 2. When the electric drawer 2 cabinet is powered on, the opening and closing of the drawer 2 is driven by the synchronous motor 3 to drive the gear 9 rotation control, when the drawer 2 is opened and reaches the specified position, the retaining edge 13 on the drawer 2 can be against the retaining piece 14 on the cabinet body 1 to limit the drawer 2, at this time, the synchronous motor 3 no longer continues to drive the gear 9 to rotate, and the drawer 2 stops opening or closing. If the drawer 2 needs to be closed, the technicians in this field can drive the synchronous motor 3 to make the gear 9 rotate in the opposite direction to retract the drawer 2. When adopting this solution, if the electric drawer 2 cabinet is powered off, the technicians in this field can also open the electric control locking mechanism 4 by operating the operating rod 43, and pull out the drawer 2 through the operating rod 43. When the drawer 2 is manually pulled, the gear 9 can also rotate according to the tooth pattern on the rack 10, and the gear 9 will rotate in the same way when the drawer 2 is pushed back to its position. In another embodiment of the present solution, the technicians in this field can also exchange the installation positions of the lock core 42 and the lock seat 41. When the technicians in this field place objects in the drawer 2, the pressure sensor 5 can sense and send a signal to inform the technicians in this field. The pressure sensor 5 in this solution can sense whether there are objects placed in the drawer 2, and the sensing method is simple.
