Handle lock

A handle lock, comprising:

• a lock seat, wherein a fixed surface is formed at a bottom surface of the lock seat;
• two lock bars, wherein the two lock bars are respectively arranged at an upper and a lower end of the lock seat in a pivotal and movable mode;
• two pivoting surfaces arranged at an angle of 45° to the fixed surface, wherein each of the two pivoting surfaces is arranged between the two lock bars and the lock seat, and
• two pivot axes arranged perpendicular to the two pivoting surfaces, wherein the two lock bars are arranged rotatable around each of the two pivot axes at first ends thereof to switch between a locked state and an unlocked state;
• in the locked state, the two lock bars are arranged in a way of being perpendicular to the fixed surface;
• when releasing the locking, the two lock bars rotate around each of the two pivot axes leftwards or rightwards to make the two lock bars rotated to a position upwards or downwards to form the unlocked state in which the two lock bars are at an angle of approximately 180° to each other;
• wherein first rotatable members are arranged on the lock seat, the two lock bars are each provided with a second rotatable member, the first rotatable members are each a cylindrical cavity, the second rotatable member is a cylindrical member, the cylindrical member is inserted into the cylindrical cavity, so that the two lock bars are rotatably arranged on the lock seat, and the center line of the cylindrical member is the two pivot axes;
• the two lock bars each comprise a lock bar sleeve, a lock bar connecting member and a lock tongue member, the lock bar connecting member and the lock tongue member are installed in a cavity formed by the hollow inside of the lock bar sleeve, the lock bar connecting member is fixedly connected to the lock bar sleeve, the lock tongue member is arranged in a mode of retractable movements relative to the lock bar connecting member in a length direction of the two lock bars, and the second rotatable member is arranged at a first end of the lock bar connecting member;
• first limiting members are arranged on the lock seat, a second limiting member is arranged on each of the two lock bars, the second limiting member is a lock tongue and formed at a first end of the lock tongue member, limiting cavities are formed on an upper and a lower side of the lock bar connecting member respectively, two second limiting members are disposed and assembled in the limiting cavities respectively, and the first limiting members are composed of locking cavities and are arranged on an upper side and a lower side of the cylindrical cavity;
• when the lock bar connecting member extends toward the first ends of the two lock bars, the two second limiting members extend into the first limiting members to lock the rotation of the two lock bars to form the locked state;
• and when the lock bar connecting member is displaced toward second ends of the two lock bars, the two second limiting members are disengaged from the first limiting members to release the rotational locking of the two lock bars to form the unlocked state;
• and
• first pivoting surfaces are provided on the lock seat, and second pivoting surfaces are provided on the two lock bars, the first pivoting surface and the second pivoting surface are propped against each other when the two lock bars are mounted to the lock seat to form the two pivoting surfaces.
