Box cover locking device

Abstract

The invention provides a box cover locking device, which comprises an electromagnet. A permanent magnet is arranged on a box cover. The magnetic pole of the electromagnet is opposite to the magnetic pole of the permanent magnet, so that the box cover can be opened by the repulsion force generated between the electromagnet and the permanent magnet on the box cover when the electromagnet is powered on. When the electromagnet is powered off, the electromagnetic force of the electromagnet disappears, and an iron core of the electromagnet is attracted by the permanent magnet so that the box cover is closed. The box cover locking device has the advantages that the reliability in use of the locking device is improved since motion components, extra holes and plug-in and plug-out mechanisms are omitted; power consumption is reduced and the self-holding time of an automatic storage management system is prolonged by the aid of the design that the box cover is opened when the electromagnet is powered on and is closed when the electromagnet is powered off. The invention further provides a controllable storage box comprising the box cover locking device and a drug consumable storage system comprising the controllable storage box.

Description

Technical field: [0001] The invention relates to a box cover switch technology, in particular to a box cover locking device of a controllable medicine box. Background technique: [0002] The management of common drugs, anesthetics and consumables has always been a difficult problem for each hospital. At present, domestic hospital drugs (including anesthetics and non-anesthetics in operating rooms) and consumables are stored in ordinary medicine cabinets. Basically, it is manually registered by drug administrators or medical staff. This management and storage method is difficult to ensure the safety of drug storage and use. Drug management is inefficient, consumes a lot of manpower and material resources, and has a high error rate. [0003] In order to solve the problem of drug access and management, the United States currently has several types of drug management cabinets for operating rooms. There are drawers inside, and the sensors on the back of the drawer and the medici...

AI Technical Summary

Problems solved by technology

The disadvantage of such a locking method is that once the power supply of the lid locking device is cut off or the main power supply of the access system is exhausted, the electromagnet core of the lid locking device loses the electromagnetic force, and the lid of the medicine box may The lock will be unlocked, causing accidental opening of the medicine box, causing leakage or loss of medicine

Moreover, in the actual use process, the lid of the controllable medicine box is generally in a closed state, and the existing electromagnetic control type lid locking device is always in a power-on state when the medicine box is closed, which increases the power consumption. At the same time, when the external power supply is disconnected, the self-sustaining time of the drug access system is greatly reduced when it is running on its own backup power supply, which reduces the reliability of the system
