A locking mechanism of a door and window handle as shown in fig. 1-5, comprising a handle 10, a handle head 20 and a panel 30; the handle head 20 is rotatably hidden on the panel 30; the locking mechanism of the door and window handle further comprises a first locking assembly 40 and a second locking assembly 50; the first locking assembly 40 is used for locking the handle head 20 on the panel 30, i.e. the handle head 20 cannot rotate relative to the panel 30; the handle 10 is rotatably mounted on the panel 30 and actively linked to the handle head 20 via a linkage assembly 60; the second locking assembly 50 comprises a first resilient member 51, a first stop structure 52 provided on the handle 10 and a second stop structure 53 provided on the panel 30; the handle 10 is also movable relative to the panel 30 between a position in which the first stop formation 52 is in a snug fit with the second stop formation 53 and a position in which the first stop formation 52 is disengaged from the second stop formation 53; that is, when the handle 10 moves relative to the panel 30, the first limiting structure 52 can be inserted into the second limiting structure 53 under the linkage of the panel 30, and at this time, the handle 10 cannot rotate relative to the panel 30, or the first limiting structure 52 can be disengaged from the second limiting structure 53 under the linkage of the panel 30, and at this time, the handle 10 can rotate relative to the panel 30; the first elastic element 51 is used for providing elastic stress for urging the handle 10 to link the first limiting structure 52 and the second limiting structure 53 for insertion fit; the handle 10 is also fixed with a release 70; the release member 70 is used for releasing the first locking assembly 40 from locking the handle head 20 when the first limit structure 52 is disengaged from the second limit structure 53, and the handle head 20 can rotate relative to the panel 30.
On the basis of the above structure, when the handle 10 needs to be rotated and the handle head 20 needs to be linked to rotate, the handle 10 is moved (the movement here can be pressing or stretching the handle 10, and as shown in the structure of fig. 2, namely pressing the handle 10) to overcome the elastic stress of the first elastic element 51, so that the handle 10 is linked with the first limit structure 52 to move towards the direction away from the second limit structure 53, and thus, when the first limit structure 52 is separated from the second limit structure 53, the locking of the handle 10 on the panel 30 is released; meanwhile, when the first limit structure 52 is disengaged from the second limit structure 53, the release piece 70 on the handle 10 releases the locking of the first locking assembly 40 to the handle head 20; thus, the handle 10 can be rotated, and the handle head 20 is linked to rotate under the action of the linkage assembly 60, so that the handle head 20 is linked with the external bolt to move; the above process improves the difficulty of rotating the handle 10 and the handle head 20 through the cooperation of the first elastic element 51, the first limit structure 52, the second limit structure 53 and the first locking assembly 40, and further reduces the possibility of mistaken opening of the door and window handle.
The first elastic element 51 may be an elastic sheet or an elastic column; the utility model discloses preferred following embodiment: the first elastic element 51 is a first return spring, and two ends of the first return spring respectively abut against the handle 10 and the panel 30.
Specifically, the first limit structure 52 may be a groove formed on the handle 10, and correspondingly, the second limit structure 53 may be a block fixed on the panel 30; or, the first limiting structure 52 is a limiting block fixed on the handle 10, and correspondingly, the second limiting structure 53 is a limiting groove formed on the surface of the panel 30, because the surface of the panel 30 is relatively flat, the limiting groove is easy to process, and compared with a groove formed on the handle 10, the construction difficulty can be reduced.
In practical application, the number of the limiting grooves can be one or more, and correspondingly, the number of the limiting blocks can also be one or more. In order to improve the locking effect on the handle 10, preferably, the number of the limiting grooves is four, and four limiting grooves are circumferentially distributed; the number of the limiting blocks is four, and the four limiting blocks are arranged in one-to-one correspondence with the four limiting grooves.
The linkage assembly 60 includes a first linkage 61 provided on the handle 10 and a second linkage 62 provided on the handle head 20; the first linkage structure 61 and the second linkage structure 62 are inserted and matched, so that the handle 10 drives the first linkage structure 61 when rotating, and the first linkage structure 61 pushes the second linkage structure 62, thereby realizing linkage of the handle head 20; the first linkage 61 and the second linkage 62 are movable relative to each other in the direction of movement of the handle 10 to facilitate movement of the handle 10.
Specifically, the first linkage structure 61 is a linkage groove formed on the handle 10; the second linkage structure 62 is a linkage block fixed on the handle head 20; alternatively, the first linkage 61 is a block fixed to the handle 10; the second linkage 62 is a slot cut into the handle head 20.

The second elastic element 43 may be an elastic column, an elastic sheet, etc.; the second elastic element 43 in the present embodiment is preferably a second return spring; the second return spring has both ends fixed to the panel 30 and the insertion portion 42, respectively.
Further, the panel 30 is formed with an inner cavity in which the handle head 20 is disposed to protect the handle head 20 and to make the appearance more beautiful.
In order to ensure that the handle head 20 is also rotated when the handle 10 is rotated, it is preferable that the locking mechanism of the present door and window handle further includes a fitting 80, a striking block 90, and a third elastic member 100; the assembly part 80 is fixed on the handle head 20, and the central axis of the assembly part 80 is coincided with the rotation axis of the handle head 20; the assembly part 80 is provided with a plurality of grooves which are sequentially arranged at intervals around the central axial direction thereof; the impact block 90 is mounted on the panel 30 through a third elastic element 100 and movably inserted into one of the grooves; thus, the assembly part 80 is driven to rotate when the handle head 20 rotates, the power of the assembly part 80 compresses the third elastic element 100, so that the impact block 90 repeatedly enters into the other groove from one groove, at the moment, the third elastic element 100 repeatedly compresses and extends, and the elastic stress obtained by the compression of the third elastic element 100 enables the impact block 90 to generate impact force on the groove wall of the groove, so as to make a sound; thus, the handle head 20 can be ensured to rotate by sound; the impact block 90 may be a ball, and accordingly, the groove is a semicircular groove.
The third elastic element 100 may be a spring, an elastic column, an elastic sheet, or the like.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
