Technical Field

The invention belongs to the technical field of locks, and particularly relates to a handle locking mechanism and a door lock thereof.

Background

The top and bottom lock is a lock which can lock the upper and lower braking bolts (corresponding top and bottom locks) of the door while closing the lock, and the general working principle is as follows: when the door is opened, the lock core is opened by a key, the square bolt retracts, the handle is pressed downwards for a certain angle, the inclined bolt retracts, the upper brake bolt and the lower brake bolt are driven to retract, the door is opened, after the handle is released, the inclined bolt extends out, and the handle can return; when the door is locked, the handle is lifted by a certain angle to drive the upper and lower brake bolts to extend out, the lock core is locked by a key or an indoor operating knob, the square tongue extends out and is locked, the door is locked, and the handle can return after the handle is released. When the door is locked, the door is simultaneously limited by the upper and lower braking bolts, the dead bolt and the latch bolt, so that the door has better safety.

However, the top-bottom lock in the prior art can still be in the state of pushing down the unblock after the handle resets after the locking operation of carrying out top-bottom lock, ground lock for in the use of reality, can accidentally unblock the locking state of top-bottom lock when appearing the mistake and touch the handle, influence the safety protection nature of lock, reduced the theftproof performance of lock, and cause the damage to the lock easily.

Disclosure of Invention

In order to overcome the above disadvantages of the prior art, an object of the present invention is to provide a handle locking mechanism and a door lock thereof, which can effectively ensure the locking state of an upper and a lower braking bolts when the door lock is in the locking state, and improve the safety performance of the door lock and the user experience.

The technical scheme adopted by the invention for solving the technical problems is as follows:

a handle locking mechanism comprises a sliding rod arranged on a lock body, a locking piece and a rotating part used for driving an upper brake bolt and a lower brake bolt of the lock body to perform locking/unlocking movement;

the sliding rod can be arranged in a sliding mode relative to the lock body, the end portion of the sliding rod is in contact connection with a lock tongue of the lock body, a first elastic piece is arranged on the sliding rod, and the lock tongue drives the sliding rod to overcome the elastic force of the first elastic piece when retracting;

the locking piece with the slide bar transmission is connected, when the spring bolt stretches out the slide bar drives the locking piece moves to blockking the rotational motion of rotation portion.

Preferably, a guide surface is obliquely arranged at a contact position of the sliding rod and the lock tongue.

Preferably, the locking piece comprises a first side portion and a second side portion which are connected in an angle mode, a positioning column is arranged at the joint of the first side portion and the second side portion in a protruding mode, and the locking piece is arranged on the lock body in a swinging mode through the positioning column.

Preferably, the sliding rod is convexly provided with limiting columns in pairs, and a clamping space is formed between the limiting columns in pairs;

the first edge portion extends into the clamping space so that the locking piece can swing along with the sliding of the sliding rod.

Preferably, a bump is fixedly arranged on the rotating portion, and when the first elastic member is in a natural state, the second edge portion swings to a position below a rotating track of the bump and abuts against the bump.

Preferably, when the first elastic element is in a natural state, a straight line where the second edge is located is tangent to a rotation track of the bump.

Preferably, the rotating part includes a body, and a second elastic member for restoring the body after rotation is disposed between the body and the lock body.

Preferably, the body is provided with a mounting hole for mounting the handle, and the cross section of the mounting hole is elliptical or polygonal.

Preferably, the body is provided with a mounting groove for mounting the second elastic element, and a first opening and a second opening which are communicated with the mounting groove and are arranged in a staggered manner;

and two ends of the second elastic piece respectively extend out of the first opening and the second opening and abut against two sides of the fixed structure on the lock body.

A door lock comprising a handle locking mechanism as described above.

Compared with the prior art, the invention has the beneficial effects that:

in the scheme, the sliding rod and the locking piece are skillfully arranged, so that when the lock body is locked, the rotating part drives the upper and lower braking bolts to extend out and lock as the handle is lifted; when the locking operation is carried out, the lock tongue abutted to the sliding rod is in an extending state, the first elastic piece is restored to a natural state and simultaneously drives the sliding rod to reset, and the locking piece can move to abut against the rotating part at the moment, so that the handle is blocked when being pressed downwards; therefore, when the door lock is in a locking state, the unlocking action of the upper and lower brake bolts caused by accidental touch of the handle is effectively avoided, and the use safety of the door lock is ensured. Meanwhile, the handle can not be pressed down to unlock the door lock when the lock tongue is in the state of extending out and locking, so that the anti-theft performance of the door lock is greatly improved; the use experience of the user is further improved. This scheme compact structure and design benefit can effectively realize the locking of handle through the mutual linkage between each spare part and keep, and whole easy operation is convenient, and the facilitate promotion is used.
