[0001] The present application relates to the technical field of doors and windows, and in particular to a door and window handle. Background Art

[0002] With the diversification of modern family lifestyles, the number of families with pets and young children is increasing, which brings new challenges to home safety. The design of traditional door and window handles often focuses on the convenience of use and basic safety needs of adults, but its protection function is insufficient when facing curious and active children and lively pets. Due to the limitations of height, strength and other factors, children often find it difficult to understand the potential dangers of door and window operation. They may inadvertently open the doors and windows, leading to accidents, such as getting lost, falling and other safety risks. Similarly, pets, especially cats and dogs, may touch the door and window handles by jumping, allowing them to easily apply force to the handles through their weight or claws, causing the doors and windows to open unexpectedly, which may not only put the pets themselves in danger, such as escape and injury, but also cause family property safety issues.

[0003] In this regard, the present application proposes a door and window handle to solve the problem. Summary of the invention

DETAILED DESCRIPTION

[0026] like Figures 1 to 6 As shown, a door and window handle comprises a base 1, a connecting piece 2, a handle 3, a torsion spring 4 and a combination part 5.

[0027] The base 1 is used to connect with doors and windows, and a connecting ring 6 is installed thereon, and a mounting sleeve 601 is fixedly provided on the inner wall of the connecting ring 6 .

[0028] Furthermore, a transmission rod 201 is installed on the connecting member 2. The transmission rod 201 is square and connected to the locking point of the door and window. A connecting groove is opened at one end of the connecting member 2, and a through groove is opened in the connecting groove.

[0029] Furthermore, the handle 3 is rotatably arranged inside the connecting ring 6, a connecting hole is opened at one end of the handle 3, and a through hole connected to the connecting hole is opened at the other end, the transmission rod 201 is rotatably arranged inside the connecting hole, and a locking groove is also opened in the connecting hole, and a support member 301 is installed at the bottom of the handle 3.

[0030] Specifically, the connection groove on the connection member 2 and the connection hole on the handle 3 together create a cavity for accommodating the combination part 5 .

[0031] Furthermore, one end of the torsion spring 4 is connected to the support member 301 , and the other end is connected to the mounting sleeve 601 , and is used to reset the handle 3 so that the handle 3 maintains a state in a non-operating state.

[0032] Further, such as Figures 4 to 6 As shown, the combination part 5 includes a first spring 501, a second spring 502, a driving block 503, a trigger plate 504 and a locking block 505, wherein the locking block 505 is slidably disposed in the through slot.

[0033] Furthermore, the main body of the driving block 503 is trapezoidal, and a square rod 506 is installed on it. An operating rod 507 is installed at one end of the square rod 506. The operating rod 507 is slidably set in a through hole opened on the handle 3. By pressing the operating rod 507, the square rod 506 is driven to move, thereby moving the driving block 503.

[0034] Furthermore, a baffle 508 is installed on the square rod 506, and the baffle 508 is connected to one end of the first spring 501. A positioning plate 509 is also slidably provided on the square rod 506, and the positioning plate 509 is installed inside the connecting hole. The positioning plate 509 is connected to the other end of the first spring 501. The positioning plate 509 cooperates with the square rod 506 to limit the movement of the driving block 503, so that the driving block 503 only moves in a straight line and does not rotate along the through hole.

[0035] Furthermore, a connecting rod 510 is installed at one end of the locking block 505, and the connecting rod 510 is connected to the trigger plate 504. The trigger plate 504 is forced to move, thereby driving the connecting rod 510 to move, and driving the locking block 505 to move in the through groove.

[0036] Furthermore, one end of the second spring 502 is connected to the trigger plate 504 , and the other end is mounted on the inner wall of the connecting groove. When the trigger plate 504 is not subjected to force, the trigger plate 504 is positioned at a set position under the force of the second spring 502 .

[0037] Further, the following status is provided;

[0038] In the first state, the handle 3 is held but the operating rod 507 is not pressed, the locking block 505 is not inserted into the locking groove, and the handle 3 is turned. The force on the handle 3 is not transmitted to the connecting member 2, and the door or window cannot be opened;

[0039] In the second state, the handle 3 is held and the operating rod 507 is pressed at the same time, the locking block 505 is inserted into the locking groove, and the handle 3 is rotated. The handle 3 synchronously drives the connecting member 2 and the transmission rod 201 to open the door and window.

[0040] It should be noted that, in the present application, the minimum force generated by the first spring 501 and the second spring 502 is set at a threshold value greater than the operating ability of a typical child.

[0041] A door and window handle, the working principle is as follows:

[0042] When it is necessary to open the door or window, the operating rod 507 must be pressed while holding the handle 3. The operating rod 507 is forced to drive the square rod 506 and the baffle 508 to move. The movement of the baffle 508 synchronously squeezes the first spring 501. The square rod 506 drives the driving block 503 to move. The two inclined surfaces on the driving block 503 synchronously contact the trigger plate 504. The trigger plate 504 is forced to drive the connecting rod 510 to move while squeezing the second spring 502, and synchronously drives the locking block 505 to move, so that the locking block 505 is inserted into the locking groove. At this time, the handle 3 and the connecting member 2 are locked. When the handle 3 is turned, the connecting member 2 is synchronously driven to complete the unlocking operation. If only the handle 3 is held without pressing the operating rod 507, the unlocking cannot be performed.

[0043] When the operating rod 507 is released, the baffle plate 508 is driven to reset under the restoring force of the first spring 501, thereby driving the square rod 506 and the driving block 503 to reset. Under the restoring force of the second spring 502, the trigger plate 504 is driven to reset, thereby driving the connecting rod 510 and the locking block 505 to reset.
