[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] like Figures 1 to 6 As shown, a control and transmission system for doors and windows provided by an embodiment of the present invention can be applied to narrow-side doors and windows and fully concealed casement windows, including a handle component 10 and a transmission component 20 mounted on both sides of a profile 90, and the transmission component 20 is driven by the handle component 10, and the handle component 10 and the transmission component 20 are connected by a locking member 30, which can be a screw; the transmission component 20 includes a transmission main body that can be embedded in the profile groove 901, and the handle component 10 includes a handle main body exposed on the side of the profile 90, and the handle main body includes a handle handle 11. In this way, when applied to the narrow-side profile 90 of narrow-side doors and windows, only the handle part is exposed, and the main body or the entire transmission component 20 can be located in the profile groove 901. It has a small and compact structure, beautiful appearance, does not block the field of view of doors and windows, and provides a good user experience.

[0025] Specifically, the handle component 10 also includes an active part 12 linked to the handle handle 11. The active part 12 can be a gear (sector-shaped teeth). The transmission component 20 also includes a transmission rod 21. The transmission rod 21 can drive the locking point of the doors and windows. A driving mechanism is provided between the active part 12 and the transmission rod 21. When the handle handle 11 is operated, the transmission rod 21 of the transmission component 20 is moved through the driving mechanism to achieve locking and unlocking of the doors and windows. In this embodiment, the transmission rod 21 is a bidirectional transmission rod 21, and the handle can rotate forward and reverse, thereby driving the transmission rod 21 to slide forward and reverse accordingly.

[0026] Specifically, the active part 12 is a rotatable toothed component, and the transmission rod 21 is connected to a sliding fork 22; the driving mechanism includes a rotating rocker rod 23, one end of which is provided with a tooth portion that engages with the toothed component, and the other end of the rotating rocker rod 23 is connected to the sliding fork 22, and the middle part of the rotating rocker rod 23 is rotatably connected to the handle component 10.

[0027] Specifically, the sliding fork 22 is provided with a connecting groove 221 perpendicular to the sliding direction, and the rotating rocker 23 is provided with a connecting rod (sliding column) 231 that can be slidably connected to the connecting groove 221. In this way, when the handle 11 is rotated, the rotating rocker 23 can rotate, thereby driving the sliding fork 22 to drive the transmission rod 21 to slide. The connecting rod 231 can extend into or pass through the connecting groove 221. The rotation point of the rotating rocker 23 can be close to the active member 12. In this way, when the rotating rocker 23 rotates by the same angle, the rotation stroke of its other end can be greater, achieving a larger transmission distance within a limited space. In this embodiment, when the product handle is rotated 90 degrees, the stroke of the bidirectional transmission rod 21 can reach 18 mm or more.

[0028] As an alternative to the above-mentioned rocker mechanism, refer to Figure 7 As shown, the active member 12 is a rotatable toothed member (e.g., sector teeth), and the driving mechanism is a rack and pinion mechanism (gear and T-pin mechanism). The driving mechanism includes teeth 291 provided on the toothed member and a rack 292 provided on the sliding fork 22. The transmission structure is simple and reliable. The rack 292 can be T-shaped as a whole and can serve as a shift fork.

[0029] Specifically, the handle component 10 also includes a handle seat 13, and an elastic positioning structure is provided between the handle 11 and the handle seat 13. The profile 90 can be provided with an oblong mounting groove 902, and the handle seat 13 can be installed in the mounting groove 902; the transmission component 20 is disposed in the profile groove 901 (C-shaped groove).

[0030] Specifically, the elastic positioning structure includes a spring piece 41 and a plurality of positioning steel balls 42. The spring piece 41 is clamped between the handle 11 and the handle base 13. Each positioning steel ball 42 is arranged on one side of the spring piece 41. It does not require the use of a metal coil spring with a long axial length, and the structure is compact. The spring piece 41 can be in the shape of a ring, and a plurality of corresponding holes 411 are provided on it. The holes 411 are connected to the outer periphery of the spring piece 41, and the spring piece 41 has good elasticity.

[0031] Specifically, the handle 11 is connected to a handle shaft 111, and the handle shaft 111 passes through the spring 41 and extends into the handle seat 13 and is connected to the active component 12. The handle seat 13 includes a seat body 131 and a mounting shell 132. The side end of the mounting shell 132 is connected to the handle 11, and the lower end is integrally connected to the seat body 131. The mounting shell 132 has a mounting cavity, and the active component 12, the driving mechanism, etc. can be arranged in the mounting cavity. The side end surface of the mounting shell 132 can be provided with a plurality of limiting recesses 130, and the limiting recesses 130 can be spherical. The positioning steel ball 42 is stuck in the limiting recess 130 and the hole 411 of the spring 41. A plurality of limiting recesses 130 can be provided, and each limiting recess 130 is evenly distributed along the circumference.

[0032] Specifically, a friction plate 43 is provided between the handle 11 and the handle base 13, which provides a good operating feel.

[0033] Specifically, the sliding fork 22 is detachably connected to the transmission rod 21 , and the sliding forks 22 of different heights can be replaced according to the profiles 90 of different thicknesses, thereby improving the versatility of the product.

[0034] Specifically, the transmission component 20 also includes a profile groove panel 25 arranged in the profile groove 901. The profile groove panel 25 can cover the opening of the profile groove 901. The transmission rod 21 can be slidably connected to the inner side of the profile groove panel 25 through a connecting piece, and the connecting piece can be a rivet shaft 26 (riveting shaft).

[0035] In specific applications, the handle can be installed from the side of the profile 90, and after installation, only the handle is exposed, without affecting the field of vision. The transmission component 20 and the handle component 10 are installed horizontally and fixed with screws, making installation convenient and quick. The handle component 10 can use a gear and rocker mechanism inside, which ensures smooth transmission and achieves a large transmission distance within a limited space. The handle is positioned using a positioning steel ball 42 and a spring shrapnel 41, which helps save space for the handle height. The handle component 10 and the transmission component 20 are connected and transmitted via a shift column and a shift fork. Changing the shift fork length can adapt to profiles 90 of different thicknesses, which has strong versatility.

[0036] A control and transmission system for doors and windows provided in an embodiment of the present invention, when applied to a narrow-edge profile 90 of a narrow-edge door and window, has only the handle portion exposed, and the main body or the entire transmission component 20 can be located in the profile groove 901. It has a small and compact structure, beautiful appearance, does not block the view of the doors and windows, and provides a good user experience.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
