Therefore, the other end of the push plate 10 is in transmission connection through the structure of the upper pulling plate 7. The coupling opening 84 in the drive strap 8 is formed by deforming the wall of the drive strap 8, see fig. 4.

A lower shifting piece 14 is further arranged in the lock body 1, the lower shifting piece 14 is sleeved on the lower end of the shifting sleeve 6 in a clearance mode, the lower shifting piece 14 is also provided with a structure which is similar to the upper shifting piece 7 and used for being sleeved with the shifting sleeve 6, and the shifting sleeve 6 can also have a certain circumferential movement allowance corresponding to the lower shifting piece 14. The lower pulling sheet 14 is fixed with an inserting column 15, the other end of the driving sheet 8 is provided with an inserting groove 82, the inserting groove 82 is positioned at the position of the connecting port 84, and the inserting column 15 is inserted into the inserting groove 82 with a clearance.

The lock is unlocked indoors by using the handle, the handle is used for driving the shifting sleeve 6 to rotate clockwise at the position shown in figure 1, the shifting sleeve 6 drives the upper shifting piece 7 to rotate clockwise, the third shifting block 73 pushes the transmission piece 8 leftwards, the transmission piece 8 drives the gear 13 and the pressing piece 11 to rotate clockwise together, the shifting column 12 on the pressing piece 11 enables the supporting plate 3 to drive the main lock bolt 2 to completely retract towards the inside of the lock body 1, and the second shifting block 72 enables the oblique tongue component 5 to completely retract into the lock body 1. After the inner handle is released, the oblique bolt component 5 can elastically extend out of the lock body 1. When utilizing the handle to lock the door indoor, anticlockwise rotation handle, dial cover 6 and drive down plectrum 14 and also anticlockwise rotate, and the cover 16 of dialling at this moment can have certain activity in the recess on last plectrum 7, and lower plectrum 14 makes the drive plate 8 move right, and when the drive plate 8 moved right, can make gear 13 and preforming 11 anticlockwise rotation, and the post 12 of dialling on the preforming 11 can make layer board 3 drive main lock plunger 2 and stretch out completely towards the outside of lock body 1.

This quick unlock can also utilize the handle to lock fast in the outside of door, can set up limit structure on this handle, and make the handle can only be at certain angle internal rotation. The shifting sleeve 6 is composed of two single bodies, the inner door handle is connected with the inner single body, the outer door handle is connected with the outer single body, the outer single body is sleeved with the inclined tongue shifting piece, and the inclined tongue shifting piece and the inclined tongue component 5 are arranged on the inclined tongue shifting piece. After the door is closed, the latch bolt plectrum can move outside the door through the handle, thereby realizing the opening of the latch bolt.

In order to ensure the anti-theft effect, the relative arrangement position between the dial post 12 and the gear 13 can be considered. When the main bolt 2 is fully extended to the outside of the lock body 1, the axis line of the column 12 and the gear 13 is located in the moving direction of the main bolt 2. Furthermore, by arranging the torsion spring 16 in the lock body 1, one end of the torsion spring 16 acts on the poking column 12, and the other end of the torsion spring 16 acts on a column body arranged on the bottom surface of the lock body 1. This allows the deadbolt 12 to provide a stable support of the extended state of the main bolt 2, in order to avoid the technical unlocking of the lock by a tool that would rigidly push the main bolt 2 into the lock body 1.
