[0028] Refer to Figures 1-7As shown in the figure, as an embodiment of the present utility model, a handle lock is provided, which includes a lock base 1 and a lock handle 2. The lock base 1 is used to be installed on the cabinet door. An assembly cavity 11 is formed in the lock base 1. A limiting groove 12 is opened on one side of the assembly cavity 11. The lock handle 2 includes a handle part 21 and a locking part 22 that are mutually L-shaped. The locking part 22 is coaxially assembled in the assembly cavity 11. An internal circuit, a driving member, a locking tongue member 6 and an elastic member 7 that cooperate with each other are installed in the locking part 22. The elastic member 7 is a spring. The internal circuit is electrically connected to the driving member and controls the driving member to rotate forward or backward. A relief hole 8 corresponding to the limiting groove 12 is opened on the circumferential side wall of the locking part 22. The elastic member 7 is installed between the first end of the locking tongue member 6 and the inner wall of the locking part 22;

[0029] When the driving member rotates forward, the second end of the locking tongue member 6 is driven to retract into the relief hole 8 and the limiting cooperation with the limiting groove 12 is released, so that the lock handle 2 can rotate relative to the lock base 1 to unlock;

[0030] When the driving member rotates backward, under the elastic force of the elastic member 7, the second end of the locking tongue member 6 extends out of the relief hole 8 and is in limiting cooperation with the limiting groove 12, realizing the locking and fixing between the lock handle 2 and the lock base 1.

[0031] In the above technical solution, the internal circuit controls the driving member to rotate forward and backward, and then drives the locking tongue member 6 to move back and forth in a straight line direction to release the limiting cooperation with the limiting groove 12 or perform locking and limiting cooperation, so as to realize the rotational unlocking or locking and fixing between the lock handle 2 and the lock base 1. There is no need to set a lock hole and a mechanical key for locking and unlocking operations.

[0034] That is, when the motor 3 drives the eccentric wheel to rotate forward, the second end of the lock tongue member 6 retracts into the relief hole 8 and releases the limit cooperation with the limit groove 12. At this time, the semi-circular arc surface 51 abuts against the abutting wall 62, and the elastic member 7 compresses and stores energy, enabling the lock handle 2 to rotate relative to the lock base 1 for unlocking; when the motor 3 drives the eccentric wheel to rotate in the reverse direction, under the elastic force of the elastic member 7, the second end of the lock tongue member 6 extends out of the relief hole 8 and is in limit cooperation with the limit groove 12. At this time, the flat cut surface 52 abuts against the abutting wall 62, realizing the locking and fixing between the lock handle 2 and the lock base 1. The setting of the semi-circular arc surface 51 makes the unlocking process more gentle, smooth and stable, and the setting of the flat cut surface 52 further ensures the locking stability.
