Detailed Description
A handleless single bolt door lock according to the present invention will be described in further detail with reference to fig. 1 to 4.
A single-bolt door lock without a handle comprises a lock body 2 arranged on a door plate and a buckle box 1 arranged on a door frame, wherein the lock body 2 comprises a lock shell 21, and a bolt 22 is arranged on the lock shell 21 in a sliding mode; the two side surfaces of the lock tongue 22 facing one end of the buckle box 1 are arc-shaped surfaces 2211 which are arranged oppositely, and are provided with first magnets;
an arc-shaped groove 11 matched with the arc-shaped surface 2211 is arranged in the buckle box 1, and a second magnet attracted with the first magnet is arranged; when the door is closed, the second magnet and the first magnet generate attraction force to suck the bolt 22 out of the lock shell 21 and abut against the second magnet; when the locking piece 212 is rotated towards the bolt 22, the locking piece 212 is abutted against the bolt 22, and the bolt 22 is locked in the buckle box 1; when the door is pushed forcibly, the arc-shaped surface 2211 of the lock tongue 22 abuts against the arc-shaped groove 11, so that a part of pushing force is converted into driving force for driving the lock tongue 22 to retract, the lock tongue 22 overcomes the suction force of a second magnet in the buckle box 1, the lock tongue 22 is pushed to slide along the arc-shaped groove 11 and is separated from the locking of the arc-shaped groove 11, and the door can be opened without a handle; the door opening operation is simple and convenient;
a locking piece 212 matched with the other end part of the bolt 22 is rotatably arranged in the lock shell 21, wherein the locking piece 212 is connected with the knob towards the inner end part of the door and is connected with the lock head towards the outer end part of the door; when the door lock needs to be locked reversely, the locking piece 212 is rotated towards the bolt 22 only by rotating a knob or a key, so that the locking piece 212 is abutted against the bolt 22, and the bolt 22 is locked in the buckle box 1; the door can be unlocked only by a key, so that the anti-theft function is realized; this lock need not to set up two spring bolts 22 from top to bottom for lock structure is simpler, reduction product cost.
