AI Technical Summary
Existing lock cylinders mainly rely on a swing-lock mechanism, which results in high material and production costs. Two parts need to be combined to realize the lock body function.
A novel lock cylinder is designed where the insertion of a key pushes a rotating assembly to rotate the square rod connection. When the key is removed, a spring pushes the rotating assembly to separate, allowing the bolt to retract and the square rod to spin freely, thus simplifying the lock body structure.
It reduces material and production costs while simplifying the operation of the locking tongue and providing anti-theft functionality.

Abstract
Claims
1. A novel lock cylinder, comprising a lock shell (1), a lock cylinder assembly (2), and a square rod connecting part (3), wherein the lock shell (1) is provided with a first through hole (101), and the lock cylinder assembly (2) and the square rod connecting part (3) are respectively disposed at the front and rear ends of the first through hole (101), characterized in that: The end of the lock cylinder assembly (2) is provided with a first slot (201). A rotating assembly (4) is provided between the lock cylinder assembly (2) and the square rod connecting part (3). A first protruding strip (41) is provided on the rotating assembly (4). The rotating assembly (4) is inserted into the end of the lock cylinder assembly (2) for movable connection, and the first protruding strip (41) is inserted into the first slot (201). A first spring (5) is provided between the rotating assembly (4) and the square rod connecting part (3). A second slot (301) is provided on the square rod connecting part (3). When the key is inserted into the lock cylinder assembly (2), the key pushes the rotating assembly (4) to make the first protruding strip (41) insert into the second slot (301). The rotation of the lock cylinder assembly (2) drives the rotating assembly (4) and the square rod connecting part (3) to rotate. When the key is pulled out, the first spring (5) pushes the rotating assembly (4) to separate the square rod connecting part (3) from the rotating assembly (4).
2. A new lock cylinder as claimed in claim 1, characterized by: The rotating assembly (4) includes a rotating shell (42), a second spring (43) and a push shaft (44). The first spring (5) is disposed inside the rotating shell (42). The push shaft (44) passes through the second spring (43) and is inserted into the rotating shell (42). The push shaft (44) passes through the outside of the rotating shell (42) and is fixed by a first buckle (45).
3. A new lock cylinder as claimed in claim 1, wherein: The lock cylinder assembly (2) is provided with a first groove ring (202), the lock shell (1) is provided with a first wire groove (102), a second buckle (11) is installed on the first wire groove (102), and the second buckle (11) passes through the first wire groove (102) and is engaged with the first groove ring (202) of the lock cylinder assembly (2).
4. A new lock cylinder as claimed in claim 1, wherein: The square rod connecting part (3) is provided with a second groove ring (302), the lock shell (1) is provided with a second wire groove (103), a third buckle (12) is installed on the second wire groove (103), and the third buckle (12) passes through the second wire groove (103) and is engaged with the second groove ring (302) of the square rod connecting part (3).
5. A new lock cylinder as claimed in claim 1, wherein: The lock cylinder assembly (2) includes a lock cylinder (21), several sets of first blades (22) and several sets of second blades (23). The lock cylinder (21) is provided with several blade grooves (203). The first blades (22) and second blades (23) are disposed in the blade grooves (203). A third spring (24) is provided between the first blades (22) and the second blades (23).
6. A new lock cylinder as claimed in claim 5, characterized in that: The lock cylinder (21), the first blade (22), and the second blade (23) are provided with corresponding key slots. A limit block (25) is provided inside the lock cylinder (21). A fourth spring (26) is installed at the bottom of the limit block (25). A base plate (27) is provided at the bottom of the fourth spring (26).
7. A new lock cylinder as claimed in claim 6, characterized in that: The bottom of the first blade (22) and the second blade (23) are provided with a first groove (28), and the limiting block (25) is disposed in the first groove (28).
8. A new lock cylinder as claimed in claim 7, characterized by: The first through hole (101) on the lock shell (1) is provided with a second groove (104), and the limiting block (25) is embedded between the first groove (28) and the second groove (104) and moves up and down.
9. A lock, characterized by: The application relates to a new lock cylinder, characterized in that a square rod is installed on the square rod connecting part (3) and is inserted into a lock body.
