Description

Technical Field

[0001] This utility model relates to window handle technology, and more particularly to a window switch handle. Background Technology

[0002] With the continuous development of society and the economy, architectural forms have become increasingly diverse. Windows, which provide lighting and ventilation, typically have handles mounted on the window sash, which are turned to open or close. However, these window handles require only a simple turning motion to open the window, making them easy for children to operate. Therefore, children can easily turn these handles to open the window (i.e., the window sash), potentially leading to accidents where they fall out of the window to the ground. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model proposes a window switch handle.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] like Figures 1 to 9 As shown, this utility model of a window switch handle includes a window body 1, an outer cover 2, a rotating component 3, a rotating component 4, and a locking body 5.

[0026] A first through hole 6 is provided in the middle of the window 1. A portion of the window is shown in this application for ease of understanding. The first through hole 6 is used for the insertion of the rotating component 3, allowing it to rotate the lock cylinder inside the window 1.

[0027] The outer cover 2 is set on the window 1. The outer cover 2 can be fixed to the window 1 by bolts 222. The outer cover 2 is provided with a second through hole 7. A handle 8 is provided in the middle of the second through hole 7. The handle 8 is composed of a handle 9 and a rotating body 10. The rotating body 10 is set in the second through hole 7. The rotating body 10 can rotate and move in the second through hole 7, thereby realizing the pressing and rotating functions.

[0028] The rotating part 3 is set inside the outer cover 2 and installed in the first through hole 6. The rotating part 3 is composed of a square body 11, a disc body 12 and a cylinder 13. The disc body 12 is provided with multiple positioning protrusions 14. The maximum distance between the positioning protrusions 14 is greater than the inner diameter of the first through hole 6, so that only the square body 11 is set in the first through hole 6 on the rotating part 3.

[0029] A first spring 15 is fitted on the cylinder 13. One end of the first spring 15 is in contact with the disc 12, and the other end is in contact with the rotating part 4. When the rotating part 4 is pressed and pushed by the handle 8, it can compress the first spring 15 and cause the cylinder 13 to move within the positioning hole 16.

[0030] The outer cover 2 also includes a cover body 17, which is mounted on the window 1. Inside the cover body 17 are a second spring 18 and a locking body 5, located between two positioning protrusions 14. A sliding chamber 19 is formed in the middle of the cover body 17, and symmetrically arranged fixing parts 20 are provided on the outside of the cover body 17. The fixing parts 20 secure the cover body 17 to the window 1 using bolts. The locking body 5 has a locking part 21 and a pushing part 22. The locking part 21 is located between two positioning protrusions 14, and the cover body 17 has a third through hole 23 for accommodating the pushing part 22. The length of the third through hole 23 is greater than the length of the pushing part 22, allowing the pushing part 22 to slide within the third through hole 23.

[0031] The rotating component 4 is mounted on the cylinder 13 and is connected to the handle 8 by bolts. The rotating component 4 consists of a hexagonal part 24 and a cylindrical part 25. The cylindrical part 25 is provided with a tapered end 26 and a tapered surface 27, which contacts the pushing part 22.

[0032] The cylindrical part 25 forms an active chamber 28 in the middle, and the hexagonal part 24 is provided with a positioning hole 16 and a connecting hole 29 in the middle. The positioning hole 16 is provided with multiple limiting protrusions 30 in the middle, and the cylindrical body 13 is provided with a limiting groove 31 that cooperates with the limiting protrusions 30.

[0033] The rotating body 10 is provided with a fixing hole 32, a connecting hole 33, and a hexagonal hole 34. The connecting hole 33 connects the hexagonal hole 34 and the fixing hole 32. The hexagonal part 24 is disposed in the hexagonal hole 34. Bolts are inserted from the fixing hole 32 and the connecting hole 33 and placed in the connecting hole 29. A plug 321 can be installed in the fixing hole 32.

[0034] When the handle 8 is rotated, it can be rotated together with the hexagonal part 24 through the hexagonal hole 34.

[0035] In use, first press the handle 8, causing it to push the rotating part 4. The rotating part 4 compresses the first spring 15, while the conical surface 27 guides the pushing part 22 on the locking body 5 to move within the third through hole 23, thereby compressing the second spring 18 and keeping the locking part 21 moving. The positioning protrusion 14 is no longer restricted, allowing the handle 8 to be rotated 90°, causing the rotating part 3 to rotate as well. When the pressing force is released, the first spring 15 and the second spring 18 reset the rotating part 4, handle 8, and locking body 5. The locking part 21 is positioned between different positioning protrusions 14, continuing to restrict the rotation of the rotating part 3, improving safety and preventing children from easily prying the handle 8 to open the window.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
