Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
A sinking type fixed lock with customs unlocking prompt function is shown in figure 1, and comprises a shell 1 and various parts mounted on the shell 1. The shell 1 is provided with a password component 2, a key component 3, a button 4 and a lock hook component 5, and the fixed lock has the following two unlocking modes: firstly, the password component 2 is unlocked by inputting a correct unlocking number group through the password component 2, after the password component 2 is unlocked, the button 4 is pressed, and the button 4 drives the lock hook component 5 to move so as to realize unlocking; secondly, the unlocking key is used for unlocking the key assembly 3, and the unlocking of the key assembly 3 drives the lock hook assembly 5 to move so as to unlock.
As shown in fig. 1 and 2, the code assembly 2 comprises a code wheel set 21, a central rod 22 and a number changing piece set 23, and a central rod return spring 24 is sleeved on the central rod 22. Two transmission parts 6 are arranged between the central rod 22 and the button 4, and the two transmission parts 6 are connected with the latch hook component 5 in a linkage way through a linkage plate 7. An auxiliary inclined plane is arranged at the matched contact position of the two transmission parts 6 and the button 4, and a button return spring 40 is arranged between the button 4 and the bottom cover 12 of the shell 1. When the cipher wheel group 21 is locked, the central rod 22 cannot move along the axial direction of the central rod, so that the button 4 cannot be pressed downwards; after the password wheelset 21 is unlocked, the central rod 22 can move along the axial direction of the password wheelset, the button 4 is pressed downwards, the button reset spring 40 generates elastic deformation, the button 4 pushes the two transmission pieces 6 to move through the auxiliary inclined plane, the two transmission pieces 6 push the central rod 22 to move, the central rod reset spring 24 generates elastic deformation, the two transmission pieces 6 simultaneously drive the linkage plate 7 to move, and the linkage plate 7 drives the lock hook assembly 5 to move to unlock.
