[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Combination Figures 1 to 5 The illustrated concealed switch door / window handle includes a mounting base 1 with a mounting groove 20. A protruding ring 22 communicating with the mounting groove 20 is provided on one side of the mounting base 1. A cover 3 is fitted onto the outer side of the protruding ring 22 and is rotatably mounted on the protruding ring 22. A positioning spindle 4 is installed within the mounting groove 20, with one end extending to the outer side of the protruding ring 22 and connected to the handle 2. A positioning piece 6 is provided on the side of the mounting base 1 facing the cover 3. The positioning piece 6 can move up and down on the mounting base 1 to contact or disengage from the positioning spindle 4, locking or unlocking the positioning spindle 4. In this embodiment, the cover 3 rotates on the protruding ring 22, allowing it to cover or expose the positioning piece 6, facilitating operation of the positioning piece 6 and locking or unlocking the positioning spindle 4. After operation, simply flicking the cover 3 will cover the positioning piece 6, preventing children from accidentally touching the switch. With the cover obscured, there are no switch-related buttons on the surface, resulting in a more aesthetically pleasing appearance and effective protection of the positioning piece 6, thus enhancing practicality.

[0022] Specifically, the positioning mandrel 4 in this embodiment includes a shaft 7. One end of the shaft 7 near the handle 3 is provided with a polygonal connecting segment 9 that connects to the handle 2. Multiple slots 8 are provided on the outer circumferential wall of the shaft 7. One end of the positioning piece 6 near the positioning mandrel 4 is provided with an insert 10. The insert 10 corresponds to the circumferential surface of the shaft 7 where the slots 8 are provided. Thus, when the positioning piece 6 is pushed to move, the insert 10 can move along with it, allowing the insert 10 to be inserted into the slot 8, thereby locking the shaft 7 and preventing the handle 2 from rotating. After the operation is completed, the positioning piece 6 can be blocked by simply moving the cover 3 to reset it.

[0023] In this embodiment, a positioning plate limiting groove 19 located on the mounting base 1 is provided on one side of the convex ring 22. A first limiting notch 11 is provided at the upper end of one side of the positioning plate 6, and a second limiting notch 13 is provided at the lower end of the other side. A first limiting bolt 12 installed in the positioning plate limiting groove 19 is provided in the first limiting notch 11, and a second limiting bolt 14 installed in the positioning plate limiting groove 19 is provided in the second limiting notch 13. The first limiting notch 11 is an L-shaped notch, and the second limiting notch 13 is an inverted L-shaped notch. The first limiting notch 11 and the second limiting notch 13 are diagonal notches. Moreover, the bolt heads of the first limiting bolt 12 and the second limiting bolt 14 can abut against the surface of the positioning plate 6, thereby limiting the positioning plate 6 within the positioning plate limiting groove 19. When the positioning plate 6 is pushed upward, the first limiting notch 11 presses against the first limiting bolt 12 to complete the stroke. When the positioning plate 6 is pushed downward, the second limiting notch 13 presses against the second limiting bolt 14 to complete the stroke.

[0024] It is worth noting that the positioning piece 6 in this embodiment has two ball bearing holes 15 located on the same straight line, and a ball bearing hole 17 is provided in the positioning piece limiting groove 19. A ball bearing 18 corresponding to the ball bearing hole 15 is installed in the main ball bearing hole 17. In some embodiments, a small spring can be provided in the ball bearing hole 17, and the ball bearing 18 abuts against the small spring. After pushing the positioning piece 6, the ball bearing 18 can switch between the two ball bearing holes 15, so that when the positioning piece 6 moves, the user can get feedback after reaching the stroke, making it more convenient and practical to use.

[0025] In this embodiment, the positioning piece 6 has a strip hole 16 at the end away from the insert piece 10 for moving the positioning piece 6; this allows the user to push the positioning piece 6 by pressing or moving the strip hole 16, making it more convenient to push and preventing the fingers from slipping on the positioning piece 6.

[0026] In this embodiment, a spindle bracket 23 is installed in the mounting slot 20. A first through hole 21 is provided at one end of the mounting slot 20 near the insert 10. A second through hole 24 is provided on the spindle bracket 23, which is connected to the first through hole 21. This allows the insert 10 on the positioning piece 6 to pass through the first through hole 21 and the second through hole 24 and be inserted into the slot 8.

[0027] like Figure 3As shown, in this embodiment, the outer wall of the polygonal connecting segment 9 is fitted with a bushing 5, and the cover 3 is located between the bushing 5 and the mounting base 1. The handle 3 is fitted onto the bushing 5 and the polygonal connecting segment 9. The bushing 5 is a bushing with a double ring surface. The end of the handle 2 is provided with a circular hole corresponding to the outer wall of one ring of the bushing 5. A polygonal hole is provided in the circular hole, so that the polygonal connecting segment 9 can be inserted into the polygonal hole of the handle 2. At the same time, the circular hole fits on the bushing 5. Under the action of the other ring of the bushing 5, a gap is formed between the handle 2 and the cover 3. The handle 2 can be rotated on the bushing 5, while the cover 3 can rotate between the bushing 5 and the mounting base 1 to prevent the surface of the cover 3 from contacting the handle 2 and causing rotational scratches on the surface of the cover 3.
