With further reference to fig. 2 and 3, an upper bolt assembly 3 and a lower bolt assembly 4 are slidably mounted in the lock body 1, and a pull rod 2 and a shift lever 5 are rotatably mounted in the lock body 1. The pull rod 2 is directly or indirectly connected or abutted with the upper plug pin assembly 3, the shift lever 5 or the lower plug pin assembly 4 in a rotating mode.

With further reference to fig. 3, in the present embodiment, the first direction is clockwise. The pull rod 2 is concentrically hinged with the pressing rod 8, a certain gap is reserved between the upper end of the pull rod 2 and the pressing rod 8 in the locking state of the door body, when the door body needs to be unlocked, the upper end of the pull rod 2 can be pressed, and then the lower end of the pull rod 2 can be tilted so as to facilitate a person to grasp the lower end of the pull rod 2. When people rotate the pull rod 2 by a certain angle along the first direction, the pull rod 2 is pressed against one end of the press rod 8 to drive the press rod 8 to rotate together. When the pressing rod 8 rotates, the pressing rod downwards supports against the upper plug pin component 3, so that the upper plug pin component 3 slides downwards. Of course, in other embodiments, the pull rod 2 may be configured in an L shape or other shapes, such that one end of the pull rod 2 directly presses against the upper plug pin assembly 3, or the upper plug pin assembly 3 is connected in a hinged manner, and the upper plug pin assembly 3 can also slide downward. In some embodiments, the pull rod 2 may also be directly or indirectly pressed or connected to the lower plug pin assembly 4, and of course, the pull rod 2 may also be directly or indirectly pressed or connected to the shift lever 5, which are all within the protection scope of the present invention. The hinged part of the pull rod 2 and the compression bar 8 is also provided with a torsion spring 10, so that the hand feeling of the rotating pull rod 2 is better, and the effect of resetting the pull rod 2 is also achieved.

Referring to fig. 3, when people rotate the pull rod 2 clockwise, the pull rod 2 can drive the upper bolt component 3 to slide downwards, and when the upper bolt component 3 slides downwards, the pull rod 5 can be driven to rotate clockwise, so that the lower bolt component 4 slides upwards, and quick unlocking can be realized. The lock body 1 is also internally provided with a resetting piece 6 for resetting the bolt component 3 and the lower bolt component 4, and when the pull rod 2 is loosened, the door body can be locked again under the action of the resetting piece 6.

When the door is required to be locked, the upper latch rod 32 extends into the wall body or the upper door frame, and the lower latch rod 43 extends into the floor or the lower door frame. Further referring to fig. 4 and 5, two ends of the shift lever 5 are oppositely provided with sliding grooves 51, the upper vertical sliding block 31 and the lower vertical sliding block 42 are respectively provided with a first pin body 33 and a second pin body 44, the sliding grooves 51 at the two ends of the shift lever 5 are respectively connected with the first pin body 33 and the second pin body 44 in a sliding manner, in this embodiment, the sliding grooves 51 are U-shaped grooves, which not only facilitates processing of the sliding grooves 51, but also facilitates sliding of the first pin body 33 and the second pin body 44. Of course, the upper and lower latch levers 32 and 43 can be linked up and down in other ways, for example, the upper vertical slider 31 and the lower vertical slider 42 are respectively provided with a transverse slot, and the two ends of the shift lever 5 are respectively provided with a sliding pin body which is slidably connected with the transverse slot, so that the upper and lower latch levers 32 and 43 can also be linked up and down. The protection scope of the present invention is that the upper latch rod 32 and the lower latch rod 43 are linked up and down by using similar means.

Referring to fig. 3 and 4, the locking assembly 7 is mounted on the pull rod 2, the stopping portion 41 matched with the locking assembly 7 is arranged on the lower latch assembly 4, and in the door leaf locking state, the locking assembly 7 abuts against the stopping portion 41, so that even if the door leaf is impacted or subjected to strong wind, the lower latch assembly 4 cannot be loosened, and the door leaf is kept in the locking state. When the lock needs to be unlocked, the pull rod 2 is rotated, the pull rod 2 drives the locking assembly 7 to support away from the stopping portion 41, and then the locking assembly 7 will not limit the sliding of the lower plug pin assembly 4. In the present embodiment, the locking assembly 7 includes a connecting rod 71 and a locking member 72, one end of the connecting rod 71 is rotatably connected to the pull rod 2, and the other end is rotatably connected to the locking member 72. Referring to fig. 3 and 4, when the pull rod 2 is rotated clockwise, the link rod 71 rotates clockwise, and the locking member 72 is driven to rotate counterclockwise, so that the locking member 72 is disengaged from the stopper 41.

Referring to fig. 2, 3 and 5, in the present embodiment, the reset member 6 includes a guide rod 61 vertically disposed in the lock body 1 and a spring 62 sleeved on the guide rod 61, the upper vertical sliding block 31 is slidably connected to the guide rod 61, one end of the spring 62 abuts against the upper vertical sliding block 31, and the other end abuts against the lower portion of the lock body 1, when the pull rod 2 is released, the restoring force of the spring 62 pushes the upper vertical sliding block 31 upward, so that the upper latch rod 32 and the lower latch rod 43 return to the original locked position. Of course, the resetting method is not limited to this, and the spring 62 may be disposed between the lower vertical sliding block 42 and the lock body 1, or other elastic members may be used to realize the resetting.

Referring to fig. 5, the lock body 1 is provided with a first limiting groove (not shown) and a second limiting groove (not shown), the upper vertical sliding block 31 and the lower vertical sliding block 42 are respectively provided with a first limiting pin 34 and a second limiting pin 45, and the first limiting groove and the second limiting groove are respectively connected with the first limiting pin 34 and the second limiting pin 45 in a sliding manner. When the upper vertical sliding block 31 and the lower vertical sliding block 42 slide along the lock body 1, the first limit pin 34 and the second limit pin 45 respectively slide in the first limit groove and the second limit groove, so as to perform the functions of limiting and guiding.
