Abstract
The utility model relates to a prevent that destruction performance is stronger mechanical lock. The mechanical lock comprises a lock shell, a lock cylinder and a lock bolt, wherein the lock bolt is arranged in the lock shell in a sliding manner, and the mechanical lock is characterized in that: the transmission end of the lock cylinder is connected with the rotating piece, the rotating piece is provided with an eccentric column, the lock bolt is provided with a long groove, and the eccentric column is located in the long groove of the lock bolt. The mechanical lock adopts the eccentric column arranged eccentrically to stir the lock bolt to move, so that the transmission structure is firmer and the anti-violence performance is stronger.
Description
Technical Field
The utility model relates to a tool to lock, concretely relates to be applied to mechanical lock on door.
Background
The general mechanical lock includes a lock shell, a lock core and a lock bolt, the lock core and the lock bolt are all installed in the lock shell, the transmission end of the lock core is connected with a toggle piece, and the toggle piece is hinged with the lock bolt. When a key is inserted into the lock cylinder to drive the transmission end to rotate, the transmission end drives the stirring piece to act, and the stirring piece drives the lock bolt to act, so that door unlocking is realized. However, since the toggle member and the lock bolt are hinged, the hinge of the conventional mechanical lock is easily damaged by violence, and the security function is lost.
Disclosure of Invention
In view of the deficiencies in the prior art, the utility model discloses the innovation provides a prevent that destruction performance is stronger mechanical lock.
The mechanical lock comprises a lock shell, a lock cylinder and a lock bolt, wherein the lock bolt is arranged in the lock shell in a sliding manner, and the mechanical lock is characterized in that: the transmission end of the lock cylinder is connected with the rotating piece, the rotating piece is provided with an eccentric column, the lock bolt is provided with a long groove, and the eccentric column is located in the long groove of the lock bolt.
The lock bolt is provided with a main body part and a bolt head part, the long groove is positioned on the main body part, a limiting step is formed between the bolt head part and the main body part, the lock shell is provided with a slotted hole for the bolt head part of the lock bolt to pass through, and the limiting step of the lock bolt is limited in the lock shell.
According to the utility model provides a pair of mechanical lock, owing to adopt eccentric settings's eccentric post to stir the set bar and remove to it is more firm to make transmission structure, and anti violence performance is stronger.

1. A lock case; 2. a key; 3. a lock cylinder; 5. a lock bolt; 4. a rotating member; 40. an eccentric column; 50. a long groove; 51. a main body portion; 52. a plug head portion; 53. and a limiting step.
Detailed Description
As shown in fig. 1 and 2, the mechanical lock includes a lock case 1, a lock cylinder 3 and a lock bolt 5, the lock cylinder 3 and the lock bolt 5 are installed in the lock case 1, and a key 2 is inserted into the lock cylinder 3 to rotate so as to rotate a driving end of the lock cylinder 3 to drive the lock bolt 5, so that the lock bolt 5 is slidably installed in the lock case 1, when a front end of the lock bolt 5 comes out of the lock case 1, the door is latched, and when the front end of the lock bolt 5 enters the lock case 1, the door is unlatched.
In order to drive the locking bolt 5 at the drive end of the lock cylinder 3, the drive end of the lock cylinder 3 is connected to a rotor 4, which rotor 4 is provided with an eccentric cylinder 40, and the locking bolt 5 has an elongated slot 50, the eccentric cylinder 40 being located in the elongated slot 50 of the locking bolt 5. When the key 2 is inserted into the lock core 3 and rotated, the eccentric column 40 on the rotor 4 moves in the elongated slot 50 of the lock bolt 5, and the eccentric column 40 of the rotor 4 shifts the lock bolt 5 due to the eccentricity of the eccentric column 40 relative to the rotation point of the rotor 4. Compared with a hinge connection mode, the structure has no specific connection structure, only the eccentric column 40 acts in the long groove 50 of the lock bolt 5, and only the inner walls of the eccentric column 40 and the long groove 50 of the lock bolt 5 are stressed under the external violence, but the eccentric column 40 is not easy to twist off, so that the structure is not easy to have structural problems under the external violence, and has stronger anti-damage performance.
As shown in fig. 3, the latch 5 of the present invention has a main body 51 and a latch head 52, the elongated slot 50 is located on the main body 51, a limit step 53 is formed between the latch head 52 and the main body 51 in order to make the latch 5 extend and contract within a certain range, the lock case 1 has a slot through which the latch head 52 of the latch 5 passes, and the limit step 53 of the latch 5 is limited inside the lock case 1. When the bolt 5 is moved outwards, the bolt head 52 of the bolt 5 enters the groove of the door frame and the limit step 53 is limited in the lock case 1, so that the bolt 5 is not moved any more.
