Referring to fig. 1 to 8, a door lock with a double-locking structure includes a door lock base 1, the door lock base 1 is installed on a door metal plate 2, and further includes a handle 3 disposed at the front end of the door lock base 1 and an unlocking piece 4 disposed at the rear end of the door lock base 1, the handle 3 is connected to the unlocking piece 4, the unlocking piece 4 is connected to an external door bolt, and the door lock further includes a first locking mechanism 5 and a second locking mechanism 6 for locking the unlocking piece 4 to unlock in a rotating manner. The external door lock tongue is fixed on the movable door and can be telescopically arranged on the fixed door, so that the unlocking piece 4 is driven by rotating the handle 3 when the door is opened, and the movement of the external door lock tongue is realized. Finally, the movable door is opened. And wherein first locking mechanical system 5 is that locking handle 3 rotates, and second locking mechanical system 6 is that locking unblock piece 4 rotates, and its principle all is that the rotation is prevented and outside door spring bolt is driven and is rotated to through the design of above-mentioned two locking mechanical systems, guarantee that this lock has dual locking mechanism, the locking is more stable, safety.

Wherein the first locking mechanism 5 comprises a holding device 7 for enabling the handle 3 to be in a pressing state or a releasing state and an interference structure 8, the interference structure 8 interferes with the handle 3 in the pressing state to lock the handle to rotate, and meanwhile, the interference structure 8 is not in contact with the handle 3 in the releasing state to realize free rotation of the handle 3.

The interference structure 8 comprises an interference pin 9 arranged on the door lock base 1 and an interference cavity 10 formed by hollowing in the handle, when the handle 3 is in a pressing state, the interference pin 9 and the interference cavity 10 interfere with each other, and when the handle 3 is in a loosening state, the interference pin 9 and the interference cavity 10 do not interfere with each other to realize free rotation of the handle.

Of course, the interference structure 8 may be another structure, and specifically includes an interference groove 11 provided on the door lock base 1 and a handle 3 in the form of a non-rotating body profile 12, and when the handle is in a pressed state, the interference groove 11 and the non-rotating body profile 12 interfere with each other, and when the handle 3 is in a pressed state, the interference groove 11 and the handle 3 in the form of the non-rotating body profile 12 do not interfere with each other, and the handle is freely rotated. Preferably, the non-rotating body profile 12 is diamond-shaped.

Wherein, retaining device 7's specific structure includes and is close to the dwang 13 of handle 3 and fixes guide ring 14 on unlocking piece 4, guide ring 14 on be equipped with a plurality of module 15 in turn, each module 15 in turn is including the spacing face 18 that forms between first inclined plane 16, second inclined plane 17 and first inclined plane 16 and the second inclined plane of from top to bottom slope, be formed with spacing groove 19 between each module 15 in turn, the end of dwang 13 still is equipped with turning block 20, turning block 20 on be equipped with in turn the module 15 in turn goes up the gliding first slider 21 in turn, first slider 21 on be equipped with first spring 22.

The specific operating process of the retaining device 7 with respect to the handle 3 is divided into two alternative steps, in particular:

1) the handle 3 in the loosened state is pressed downwards, at the moment, the handle 3 drives the rotating rod 13 to move downwards, the rotating rod 13 drives the first sliding block 21 on the rotating rod 13 to move downwards, so that the first sliding block 21 slides into the limiting surface 18 along the first inclined surface 16 to form limiting through the acting force of the first spring 22, and at the moment, the handle 3 is in the pressed-down state;

2) the handle 3 in the pressed state is continuously pressed downwards, at this time, the handle 3 drives the rotating rod 13 to move downwards, the rotating rod 13 drives the first sliding block 21 on the rotating rod 13 to move downwards, so that the first sliding block 21 slides into the limiting groove 19 along the second inclined surface 17 under the action of the first spring 22, and at this time, the handle 3 is in a loosened state.

Through the movement and the combination of the first locking mechanism 5, when in a pressing state, the handle 3 moves downwards for a stroke relatively to interfere with the interference structure 8 to form locking, and when in a loosening state, the handle 3 is reset and does not contact with the interference structure 8, and at the moment, the handle 3 can normally rotate.

In this embodiment, the rotating rod 13 is further provided with a second sliding block 23 for sliding back and forth in the limiting groove 19, and the rotating rod 13 is provided with a second spring 24. The fluency and indirection of the back and forth movement of the rotating rod 13 are ensured by the design of the second slider 23 and the second spring 24.

In this embodiment, the specific structure of second locking mechanism 6 includes by the arc fore shaft 25 and the rotatable lock cylinder 26 that unlock piece 4 extends to one side, lock cylinder 26 on seted up semicircular spring bolt 27, when spring bolt 27 rotated along with this lock cylinder 26, this spring bolt 27 card was gone into or was kept away from arc fore shaft 26 to it is right to realize this second locking mechanism 6 the locking or the unblock of unlock piece 4. Preferably, the lock cylinder 26 is provided with a key 28 for controlling the rotation thereof. When needs carry out the locking, thereby rotate the lock cylinder 26 through rotating key 28 for semicircular lock tongue 27 on the lock cylinder 26 is just to arc fore shaft 25, thereby unlocking piece 4 can't rotate this moment has realized the locking structure, and when semicircular lock tongue 27 on the lock cylinder 26 was back to arc fore shaft 25, unlocking piece 4 can freely rotate and open the door.

The utility model has the advantages that: this lock can have dual locking function, guarantees that the lock is more stable, safe to two locking mechanism can the exclusive use, and one of them locking mechanism can press the locking, and it is more convenient to use, and another locking mechanism can carry out the key locking, uses commonly more.

The above embodiment is only one of the preferable embodiments of the present patent, and any changes made without departing from the scope of the present patent are within the scope of the present patent.
