Description

Technical Field

[0001] This invention belongs to the field of door lock handle technology, specifically, it relates to a door lock handle for a storage box. Background Technology

[0002] Medical storage boxes are devices specifically designed for storing and protecting medical supplies and pharmaceuticals. They are widely used in hospitals, pharmacies, laboratories, and vaccine transportation, among other medical fields. Medical storage boxes provide a stable low-temperature environment to ensure the quality and efficacy of pharmaceuticals, preventing them from becoming ineffective or deteriorating during storage and transportation.

[0003] Currently, the door lock handles of medical storage boxes on the market can be divided into two categories: 1. The locking device and handle are separate devices. The handle can be embedded, external, or even handle-less. A separate action is required to unlock or lock the door. 2. The locking device and handle are integrated, but it does not support automatic locking when the door is closed. Again, a separate action is required to unlock or lock the door. Neither of these door lock handle devices can achieve automatic locking when the door is closed. The door opens and closes freely when unlocked, making operation cumbersome. Furthermore, the frequent opening and closing of medical storage boxes alters the temperature, humidity, and other environmental conditions inside, shortening the shelf life of the stored items. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a door lock handle for a storage box, aiming to solve the technical problems of existing door lock handles failing to automatically lock when closed, allowing the door to open and close freely when unlocked, and resulting in cumbersome operation. Simultaneously, the door lock handle of the storage box provided by this invention is equipped with an intelligent detection component that can detect the temperature and humidity inside the box, and promptly remind staff to make adjustments when the temperature and humidity inside the box are unsuitable for the survival of stored items.

[0005] The present invention adopts the following technical solution.

[0006] A door lock handle for a storage box includes a first handle housing, a second handle housing, and a mechanical lock assembly. The first handle housing is disposed on one side of the door, and the second handle housing is disposed on the other side of the door. The mechanical lock assembly includes a lock at the box end and a main lock at the handle end. The lock at the box end is disposed on the box of the storage box, and the main lock at the handle end is disposed inside the first handle housing.
