Background

The relocking mechanism of the door plate of the safety box is an important component of the safety box and plays a vital role in increasing the safety factor of the safety box. Generally, a door panel lock mechanism of a UL safe generally comprises a handle combination, a gate plate, a coded lock and the like, and the opening and the locking of the lock mechanism are realized by rotating the handle combination to control the extension and retraction of the gate plate. In order to increase the safety factor of the safe, a relocking mechanism is generally arranged at a main locking position so as to ensure that the self-locking mechanism can be automatically triggered to lock the flashboard after moving upwards or downwards to prevent the safe from being normally opened even if the main lock is damaged under the condition that the main lock is attacked. With the continuous development of society and the continuous upgrading of various tools and technologies, the safety of the safety box cannot be effectively guaranteed by a traditional single re-locking mechanism (upwards or downwards), and the addition of the re-locking mechanism is very necessary. According to the conventional method, a set of interlocking mechanism with upward and downward interlocking mechanisms is redesigned, the design period is long, the labor cost is high, simultaneously, the proofing is required to be carried out again, feasibility analysis is carried out, and batch production can be carried out after the interlocking mechanism is modified for many times.

Detailed Description

The invention will be further described with reference to the following specific embodiments and the accompanying drawings.

As shown in the figure: the double relocking mechanism of the UL safe comprises a flashboard 2, a coded lock 3, a first self-locking device, a second self-locking device and a self-locking baffle 1.

Wherein, flashboard 2 is installed on jam plate 11, and the middle part of flashboard 2 is opened jaggedly and is formed the opening towards the C shaped plate of inside (the left side of the figure) promptly towards jam plate 11 middle part, is equipped with trick lock 3 in the breach, and the shape of flashboard 2 and trick lock 3's position can be adjusted according to unblank position or other condition. The first self-locking device is arranged on the lock plate 11 and positioned at the upper end of the inner side of the coded lock 3, and comprises a self-locking pin 4, a first self-locking bracket 5, a flat washer 7 and a self-locking spring 8; the first self-locking support 5 is arranged on the locking plate 11, the self-locking pin 4 is arranged on the first self-locking support 5, the upper end and the lower end of the self-locking pin 4 extend out of the first self-locking support 5, and the position of the flashboard 2, which corresponds to the upper end of the self-locking pin 4, is provided with a first bayonet 2.1; the middle part of the self-locking pin 4 is provided with a flat washer 7, and a self-locking spring 8 is sleeved outside the self-locking pin 4 between the flat washer 7 and the bottom plate of the first self-locking bracket 5. The second self-locking device is arranged on the locking plate 11 and positioned at the lower end of the inner side of the coded lock 3, and comprises a second self-locking bracket 10 and a self-locking hanging plate 9; the self-locking hanging plate 9 is installed on the locking plate 11 through the second self-locking support 10, the upper end of the self-locking hanging plate 9 is bent towards one side of the coded lock 3 to form a locking hook, and the position, corresponding to the lower end of the self-locking hanging plate 9, of the flashboard 2 is provided with a second bayonet 2.2.
