Description

Technical Field

[0001] The invention relates to the technical field of safety boxes, in particular to an anti-falling safety box with a spring lock. Background Art

[0002] A safety box is usually a container for storing important items, dangerous items or items that require special protection. It generally has a sturdy shell that can resist a certain degree of external force impact, fireproof, waterproof, and anti-theft functions. For example, in financial institutions, safety boxes are used to store cash, important documents (such as contracts, bills, etc.) and valuables (such as gold and silver jewelry, jewelry, etc.); in laboratories, safety boxes can be used to store dangerous chemicals, radioactive materials, etc., and current safety boxes will open due to vibration when they fall, causing the items inside to scatter all over the floor. The present invention sets a spring lock, and when the box falls or other unexpected situations occur, it will generate severe vibration and impact force. The spring component in the spring lock plays a key role. It can elastically deform when it is subjected to impact force in an instant, absorb part of the impact energy, so that the box cover will not easily overcome the restraint of the lock and be opened due to sudden external force. Therefore, we propose a fall-proof safety box with a spring lock. Summary of the invention
