Description

Technical Field

[0001] The utility model relates to the technical field of safe boxes, in particular to a safe box door with a full-angle gear linkage lock tongue. Background Art

[0002] With the development of society and the continuous progress of technology, people have put forward higher and higher requirements for the safety and reliability of safe boxes. In the prior art, locking bolts are installed on multiple sides of the door body of the safe box, and the lock core and the locking bolts are mostly connected by a linkage method using a dial, a linkage bracket, a guide groove, and a connecting rod. This connection method has problems such as low transmission efficiency, easy occurrence of mechanical transmission failures, and loud unlocking noise. The patent with the publication number CN218029605U discloses a linkage structure for a safe box door lock. The handle of its unlocking mechanism is connected to a linkage plate through a swing shaft. Rotating the handle drives the swing shaft to swing, and then drives the linkage plate to slide left and right along the movement track of the guide chute; the side bolt connecting plate is vertically distributed close to the outer vertical edge of the door body plate, and the side bolt connecting plate is fixedly connected to the linkage plate and moves synchronously; a riveting shaft is provided on the linkage plate, and inclined chutes corresponding to the position of the riveting shaft are provided on the upper bolt connecting rod and the lower bolt connecting rod. The riveting shaft passes through the inclined chutes to connect the linkage plate with the upper bolt connecting rod and the lower bolt connecting rod. The left and right movement of the linkage plate drives the left and right movement of the riveting shaft, and the riveting shaft then drives the upper bolt connecting rod and the lower bolt connecting rod to move up and down through the inclined chutes. This transmission structure that uses a swing shaft to drive a linkage plate and then drives multiple connecting rods has problems such as low transmission efficiency, easy occurrence of connecting rod transmission failures, and loud unlocking sound.
