Description
Technical Field
The utility model relates to a self-lock device especially relates to a self-lock device of safe.
Background
With the continuous improvement of living standard of people, the safe gradually enters the daily life of people for storing valuables or various important documents. The safe is a special container, and is mainly classified into a fireproof safe, an anti-theft safe, an antimagnetic safe, a fireproof antimagnetic safe, and the like according to functions. Each safe case has the national standard, and most of the safe cases on the market have the first two types. According to different cipher working principles, the anti-theft safe can be divided into two types of mechanical safety and electronic safety, and the former has the characteristics of lower price and more reliable performance. Early safes were mostly mechanical safes. The electronic safe box applies the electronic lock with intelligent control mode such as electronic cipher, IC card, etc. to the safe box, and features convenient use, especially in hotel, the cipher needs to be changed frequently, so the safe box with electronic cipher is convenient to use. The existing locks of some safes are not safe enough and have the risk of being pried from the outside, so the problem is solved by a lock with self-locking capability after being buckled.
SUMMERY OF THE UTILITY MODEL
The utility model provides a have self-locking function behind the lock, safe self-lock device that the outside is difficult to prize has solved the not enough technical problem of safe locker security that exists among the prior art.
The above problems of the present invention are solved by the following technical solutions: a self-locking device of a safe comprises a bottom plate, a first positioning column and a second positioning column are arranged on the bottom plate, a first locking plate is sleeved on the first positioning column, a second locking plate is sleeved on the second positioning column, a first fixed column which is positioned on the same axis with the first positioning column is arranged on the first locking plate, a second fixed column which is positioned on the same axis with the second positioning column is arranged on the second locking plate, an elastic element is connected between the first fixed column and the second fixed column, a first convex angle is arranged on one side of the first locking plate close to the second locking plate, a first notch is arranged on one side of the second locking plate close to the first locking plate, the first notch and the first convex angle are opposite in position, and the first notch and the first convex angle are mutually occluded, and a second notch capable of being abutted against the first convex angle is arranged above the first notch.
The first lock piece is fixed on the bottom plate through the first positioning column and can rotate around the first positioning column; the second locking plate is fixed on the bottom plate through the second positioning column, and the second locking plate can also rotate around the second positioning column. The first locking piece and the second locking piece are connected together through an elastic element. When the self-locking device is in an opening state, the first convex angle on the first lock plate is abutted against the second notch on the second lock plate. When the self-locking device is in a closed state, the first convex angle on the first lock plate slides into the first notch below along the edge of the second notch, the first convex angle is just clamped in the first notch, the shape of the first notch is the same as that of the first convex angle, and the first notch and the first convex angle are mutually meshed. And the first locking plate and the second locking plate are connected through the elastic element, and when the first convex angle is clamped into the first notch, the two locking plates are mutually drawn to realize the self-locking function.
Preferably, the first fixing column and the second fixing column are located on the same axis, and a distance between the first positioning column and the first fixing column is smaller than a distance between the second positioning column and the second fixing column. The first positioning column and the first fixing column form an eccentric mechanism, the second positioning column and the second fixing column form an eccentric mechanism, and the two eccentric mechanisms enable the first locking plate and the second locking plate to be mutually restrained and not easy to slip.
Preferably, a lock throat which is in a U-shaped structure and into which the lock catch can be inserted is arranged at the upper end of the first locking plate.
Preferably, the elastic element is a spring, and two ends of the spring are connected with the first fixing column and the second fixing column. And a spring is used as an elastic element to enable the first locking piece and the second locking piece to be mutually restrained.
Therefore, the utility model has the advantages of as follows: when the self-locking device is in a locking state, the first convex angle on the first lock plate is mutually meshed with the first notch on the second lock plate, so that the purpose of automatic locking after the lock is buckled is realized, and the safety performance of the safe box is improved.
