To meet the convenience of daily use, such cabinets and drawers are usually not locked. In a stationary indoor environment, these designs can effectively maintain the closed state and will not automatically open, thus meeting the basic use requirements.
[0003] However, in mobile environments such as cars, trains and airplanes, due to external forces such as vibration and inertia, these traditional cabinets and drawers are prone to accidental opening during operation, resulting in damage to stored items, and even potential safety hazards to personnel. Therefore, in these special scenarios, higher performance requirements are placed on the locks of cabinets and drawers, which not only need to ensure the closing reliability in mobile environments, but also need to consider the opening and closing convenience in daily use.
