[0058] As shown in the drawings, Figure 2 , Figure 9 and Figure 10 As shown in the drawings, in this embodiment, a mounting column 28 is arranged at the rear end of the rotating shaft 4. A mounting hole 29 is formed in the lock tongue 5. The mounting column 28 is inserted and matched in the mounting hole 29. A pin hole 30 is formed in the mounting column 28 along the radial direction. A spring pin 31 is arranged in the pin hole 30. The spring pin 31 abuts against the rear side of the lock tongue 5 to prevent the lock tongue 5 from being separated from the mounting column 28.
[0059] As shown in the drawings, Figure 9 In this embodiment, the lock tongue 5 comprises a front combined plate 32 and a rear combined plate 33. An upper connecting gap is left between the upper end of the front combined plate 32 and the upper end of the rear combined plate 33. A lower connecting gap is left between the lower end of the front combined plate 32 and the lower end of the rear combined plate 33. The two ends of the front combined plate 32 are respectively connected with lock pins 34. The two lock pins 34 are respectively arranged in the upper connecting gap and the lower connecting gap.
[0060] In this embodiment, the transmission connection mode of the lock tongue 5 and the overhead lock is as follows. First, when the lock tongue 5 is mounted on the rotating shaft 4, the front combined plate 32 with the lock pins 34 is sleeved on the mounting column 28. Then, the hole on one end of the cable or connecting rod for connecting the overhead lock is matched on the lock pin 34. Then, the rear combined plate 33 is also sleeved on the mounting column 28. Finally, the spring pin 31 is inserted into the pin hole 30 of the mounting column 28 to fix the front combined plate 32 and the rear combined plate 33 on the mounting column 28. At this time, one end of the cable or connecting rod for connecting the overhead lock is connected in the upper connecting gap and the lower connecting gap, and the other end of the cable or connecting rod is connected with the overhead lock. Therefore, at this time, the lock tongue 5 is in transmission with the overhead lock.
[0061] The unlocking and locking mode of this embodiment is as follows.
[0062] When unlocking: the key is inserted into the lock cylinder 6 through the lock hole 8, so that the lock plates 27 are all retracted and hidden in the lock cylinder 6, at this time, the lock cylinder 6 can be counterclockwise rotated by the key, the rotation of the lock cylinder 6 drives the driving groove 13 to deflect, and the eccentric column 12 matched in the driving groove 13 moves with the deflection of the driving groove 13, and because the locking plate 7 is limited by the slot wall of the moving slot 10 and cannot move left and right, the locking plate 7 is driven by the driving groove 13 to translate downward and retract and hide in the rotating shaft 4 from the opening 11 of the side wall of the rotating shaft 4, and the locking plate 7 is separated from the locking slot 9 to remove the interference between the locking plate 7 and the handle seat 1, at this time, the handle 3 can be rotated to drive the rotating shaft 4 to rotate together, and the lock tongue 5 at the rear end of the rotating shaft 4 is rotated to drive the connecting cable or connecting rod to move, thereby driving the mortise lock to complete unlocking or locking.
[0063] When locking, the key is inserted into the lock cylinder 6 through the lock hole 8, so that the lock plates 27 are all retracted and hidden in the lock cylinder 6, at this time, the lock cylinder 6 can be counterclockwise rotated by the key, and the rotation of the lock cylinder 6 drives the locking plate 7 to translate upward and reset, so that the locking plate 7 extends from the opening 11 of the rotating shaft 4 and is inserted and matched into the locking slot 9, at this time, the locking plate 7 interferes with the handle seat 1 to lock the relative position of the rotating shaft 4 and the handle seat 1, and because the handle 3 is in transmission connection with the rotating shaft 4, the rotating shaft 4 cannot rotate, which also causes the handle 3 to be unable to rotate, at this time, the handle 3 cannot be rotated to unlock or lock the mortise lock.
[0064] The advantage of the embodiment is that the locking structure is built in the linkage handle of the mortise lock, the locking structure can prevent the handle from rotating relative to the handle, so that the entire mortise lock system can be locked, and the lock plate does not need to be arranged on the door frame, and the handle can be locked alone, and because the handle cannot rotate in the locking state, the user can more simply judge the state of the entire mortise lock system.
[0065] The above specific embodiments are only an explanation of the present application, and are not a limitation of the present application, and those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, but as long as the modifications are within the scope of the claims of the present application, the modifications are protected by the patent law.
