Mechanical spiral door bolt mechanism for safe box and cabinet

Abstract

The invention provides a mechanical spiral door bolt mechanism for a safe box and cabinet. The mechanical spiral door bolt mechanism is formed in a way that a gear which is provided with a pulling sheet and is arranged on the handle is engaged with a sliding rack, the sliding rack is matched with a main shaft seat provided with a main shaft, the rack is matched with the rack seat and the pulling sheet, the rack is engaged with the main shaft, the sliding rack is fixedly arranged on a connecting rod, and the handle, the main shaft seat and the rack seat are fixedly arranged on a door plate. The middle links and excessive parts are reduced and omitted, the structure is compact, the size is small, driving and transmission elements are directly and fixedly arranged on the handle, the main shaft seat and the rack seat of the door plate, the transmission interference is avoided, and all parts can be easily manufactured and assembled. The gear and the sliding rack are engaged, the main shaft is driven to move through the connecting rod, the gear drives the double-groove rack to move through the pulling sheet, inclined teeth arranged on the double-groove rack are engaged with the long rack arranged on the main shaft for driving the main shaft to rotate, the connection between the main shaft and a screw sleeve fixedly arranged on the side door frame is firm and reliable, the prying is not easy, the anti-theft performance is good, and safety and reliability in use are realized. The mechanism is arranged on the handle seat and is arranged around the handle seat, the handle is directly held for operation, middle parts do not exist, and the operation is comfortable, easy and labor-saving.

Description

technical field [0001] The invention relates to an important part of a safe cabinet lock, in particular to a mechanical screw bolt mechanism of a safe cabinet. Background technique [0002] With the continuous improvement of people's living standards, the use of safes is increasing, and people have higher and higher requirements for the quality of safes.
