The utility model provides a mechanical lock, which comprises a lock main body 100 and a first locking part 200, wherein the lock main body 100 comprises a roller mechanism and a second locking part 120, the first locking part 200 can move along a first direction and is configured to be in a locking state or an unlocking state with the second locking part 120, the roller mechanism is arranged on one side of a movement track of the first locking part 200 along a second direction, the roller mechanism is movably matched with the first locking part 200, and in the process that the first locking part 200 moves along the first direction, the roller mechanism is in friction contact with the first locking part 200 and can rotate around an axis of the first locking part 200 under the driving of friction force generated between the roller mechanism and the second locking part, and the first direction and the second direction are arranged in a crossing way.

In one embodiment, as shown in fig. 1, 2 and 3, in use, the first locking member 200 is disposed inside the lock body 100, and when the lock is in the locked state, the first locking member 200 is in a first position, in which the first locking member 200 is cooperatively connected with the second locking member 120, and the second locking member 120 is fixed to the lock body 100 with respect to the first locking member 200, so that after the first locking member 200 is connected with the second locking member 120, the first locking member 200 is locked with respect to the second locking member 120, thereby locking the lock. When unlocking is required, the first locking component 200 and the second locking component 120 are required to be separated, in this embodiment, the first locking component 200 is driven by a motor to move along a first direction, the first direction is the length extending direction of the first locking component 200, the second direction is perpendicular to the first direction, in the process of driving the first locking component 200 to move, the first locking component 200 and the roller mechanism are always in a rolling fit state, the first locking component 200 is driven to move from a first position, friction is generated between the first locking component 210 and the roller mechanism, so that the roller mechanism is driven to rotate, friction force generated by movement of the first locking component 200 is reduced, and the movement of the first locking component 200 is smoother. When the first locking member 200 moves to the second position, the first locking member 200 is separated from the second locking member 120, and the lock is in the unlocked state. After the use is finished, when the first locking part 200 is required to be locked again, the first locking part 200 is driven to move from the second position along the direction opposite to the first direction, a reverse friction force is formed between the first locking part 210 and the rolling mechanism, the roller mechanism is driven to rotate reversely, until the first locking part 200 moves to the first position, and the first locking part 200 and the second locking part 120 are in locking connection in a matching way again at the first position.
