[0043] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is 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.

[0044] like Figure 1 、 Figure 3-Figure 5 FIG. 1 is a schematic diagram of a quick-install transmission device provided by an embodiment of the present invention. The quick-install transmission device can be applied to doors and windows. It can be assembled to a sash frame profile 50 and cooperate with a fixed locking point 40 on a window frame profile 60 (or door frame profile) to achieve locking and opening of the window (or door). Figure 2 The sash frame profile 50 has a first C-shaped groove, and the quick-release transmission device of this embodiment includes a moving rod assembly, a fixed rod assembly, and a first clamping assembly 30. The fixed rod assembly is locked and fixed to the sash frame profile 50 by the first clamping assembly 30, and the moving rod assembly is slidably assembled to the fixed rod assembly. The door and window are locked and opened by the moving rod assembly sliding relative to the fixed rod assembly.

[0045] The movable rod assembly includes a first rod-shaped body 11 and a transmission lock block 12, wherein both the first rod-shaped body 11 and the transmission lock block 12 can be made of a hard material such as metal, and the cross-section of the first rod-shaped body 11 is a flat rectangle. The first rod-shaped body 11 has a plurality of locking holes 111, and the locking holes 111 respectively extend through the front and back sides (i.e., the upper and lower surfaces) of the first rod-shaped body 11. The transmission lock block 12 includes a first locking portion 121 and a locking portion 122, wherein the locking portion 122 is located on the front side of the transmission lock block 12 and is used to cooperate with a fixed locking point (the fixed locking point is fixed to the door frame profile or window frame profile 60), and the first locking portion 121 is located on the back side of the transmission lock block 12. The first locking portion 121 can be specifically made of a screw or rivet, etc., and can be integrated with the main body of the transmission lock block 12 or fixed to the main body of the transmission lock block 12 by means of a threaded connection, a tight fit, etc. Similarly, the locking portion 122 can be integral with the main body of the transmission lock block 12 or fixed to the main body of the transmission lock block 12 by welding, tight fitting, or other methods. Specifically, the locking portion 122 can include a U-shaped protrusion (with its opening facing the length direction of the first rod-shaped body 11), and the U-shaped protrusion has a C-shaped cross-sectional embedding groove. Correspondingly, the fixed locking point includes a columnar body and a raised ring located on the free end of the columnar body, and the transmission lock block 12 is locked to the fixed locking point when the raised ring is embedded in the embedding groove. Of course, the locking portion 122 and the fixed locking point can also adopt any existing structure, and will not be described in detail here.

[0046] The fixed rod assembly includes a second rod-shaped body 21, which can also be made of a hard material such as metal, and its cross section can also be a flat rectangle, and the width of the second rod-shaped body 21 (such as Figure 1The direction Y) is greater than the width of the notch of the first C-shaped groove on the window frame profile 60. Figure 3 、 Figure 4 、 Figure 5 As shown, the second rod-shaped body 21 has a second C-shaped groove 211, a first strip hole 212 and a plurality of first fixing holes 213, wherein the second C-shaped groove 211 is located on the back of the second rod-shaped body 21 and along the length direction of the second rod-shaped body 21 (as shown in FIG. Figure 1 The width of the second C-shaped groove 211 is smaller than the width of the first rod-shaped body 11 (the inner width of the second C-shaped groove 211 is larger than the width of the first rod-shaped body 11). The first strip hole 212 and the first fixing hole 213 respectively pass through the front side to the back side of the second rod-shaped body 21, and the first strip hole 212 is arranged along the length direction of the second rod-shaped body 21. The position and length of the first strip hole 212 (i.e., along the Figure 1 The dimension in the center direction (X) can be determined according to the position of the fixed locking point, the linear travel generated by the handle rotation, etc.

[0047] like Figure 3 As shown, the first clamping assembly 30 includes a first clamping piece 31 and a first clamping screw 32. The first clamping piece 31 is in the form of a sheet. Its dimension in at least one direction is larger than the width of the slot opening of the first C-shaped slot, and its dimension in another direction is smaller than the width of the slot opening of the first C-shaped slot. Thus, the first clamping piece 31 can be rotated to insert into the first C-shaped slot through the slot opening, and the first clamping piece 31 can be rotated to prevent it from being removed from the first C-shaped slot through the slot opening. Specifically, the first clamping piece 31 can be elliptical, parallelogram (with rounded corners), etc.

[0048] The movable rod assembly is slidably assembled onto the fixed rod assembly, and the first rod-shaped body 11 is inserted into the second C-shaped groove 211 of the second rod-shaped body 21 (it is understood that the width of the second C-shaped groove 211 is greater than the width of the first rod-shaped body 11, so that the first rod-shaped body 11 will not fall out of the notch of the second C-shaped groove). The first locking portion 121 of the transmission lock block 12 passes through the first strip hole 212 from the front of the second rod-shaped body 21 and is locked and fixed to the locking hole 111 of the first rod-shaped body 11. The first clamping piece 31 is assembled to the back of the second rod-shaped body 21 via a first clamping screw 32 that passes through the first fixing hole 213. The first clamping screw 32 assembles the second rod-shaped body 21 to the sash frame profile by locking the first clamping piece 31 embedded in the first C-shaped groove.

[0049] Specifically, the first clamping piece 31 may have a screw hole, and the first fixing hole 213 may be a through hole with a smooth inner wall. The first clamping screw 32 passes through the first fixing hole 213 and is threadedly connected to the screw hole on the first clamping piece 31; or, the inner wall of the first fixing hole 213 has a thread, the first clamping screw 32 is threadedly connected to the first fixing hole 213, and the first clamping piece 31 is riveted to the free end of the first clamping screw 32, so that the first clamping piece 31 can be moved close to or away from the back side of the second rod-shaped body 21 through the first clamping screw 32.

[0050] like Figure 2 As shown, when the above-mentioned quick-release transmission device is assembled to the sash frame profile 50 (the sash frame profile 50 can be installed to the window frame in advance), first rotate the first clamping piece 31 (for example, rotate the first clamping screw 32) and embed it into the first C-shaped groove 51, then rotate the first clamping piece 31 so that its longest dimension direction is perpendicular to the length direction of the first C-shaped groove 51, and then maintain the first clamping piece 31 at a fixed angle and rotate the first clamping screw 32 so that the first clamping piece 31 and the second rod-shaped body 21 clamp and fix the notch of the first C-shaped groove 51, thereby completing the assembly of the quick-release transmission device. In particular, in order to maintain the overall effect, the above-mentioned sash frame profile 50 also includes a third C-shaped groove 52, and the first C-shaped groove 51 is located at the bottom wall of the third C-shaped groove 52, and the width and thickness of the second rod-shaped body 21 are respectively adapted to the slot width and depth of the third C-shaped groove 52, so that after the assembly is completed, the second rod-shaped body 21 is embedded in the slot of another C-shaped groove and is flush with the surface of the sash frame profile 50, thereby improving the overall visual effect after assembly.

[0051] The above-mentioned quick-install transmission device is configured by providing a first clamping piece 31 on the back side of the second rod-shaped body 21, and the first rod-shaped body 11 sliding in the second C-shaped groove 211 on the back side of the second rod-shaped body 21 drives the transmission lock block 12 to slide. It can be assembled to the sash frame profile 50 after the door and window are installed, thereby realizing quick installation and post-installation of the quick-install transmission device.

[0052] like Figure 4 As shown, in one embodiment of the present invention, the bottom wall of the second C-shaped groove 211 has a plurality of strip-shaped protrusions 215 (e.g., two). These strip-shaped protrusions 215 are arranged along the length of the second rod-shaped body 21. When the first rod-shaped body 11 is inserted into the second C-shaped groove 211 of the second rod-shaped body 21, the surface of the first rod-shaped body 11 abuts against the strip-shaped protrusions 215. The strip-shaped protrusions 215 can restrain the first rod-shaped body 11 and prevent it from shaking within the second C-shaped groove 211. In a specific implementation, the strip-shaped protrusions 215 can be integral with the second rod-shaped body 21.

[0053] like Figure 5As shown, in one embodiment of the present invention, in order to reduce the noise generated by the surface friction between the transmission lock block 12 and the second rod-shaped body 21 while the transmission lock block 12 follows the movement of the first rod-shaped body 11, the fixed rod assembly includes a silent pad 22, which can be made of a polymer material such as elastic plastic and has a second strip hole 221 thereon. The silent pad 22 is assembled between the back of the transmission lock block 12 and the second rod-shaped body 21, and after the silent pad 22 is assembled in place, the second strip hole 221 and the first strip hole 212 are opposite. By adding the silent pad 22, the noise generated by the direct friction between the two hard materials (i.e., the transmission lock block 12 and the second rod-shaped body 21) can be reduced, and the wear of the transmission lock block 12 can be reduced at the same time.

[0054] In one embodiment of the present invention, the shape and size of the second strip-shaped hole 221 can be adapted to the shape and size of the first strip-shaped hole 212. Accordingly, the noise-removing pad 22 includes a sheet-shaped body 222 and a flange 223. The flange 223 protrudes from the back of the sheet-shaped body 222 and surrounds the second strip-shaped hole 221. When the noise-removing pad 22 is assembled between the transmission lock block 12 and the second rod-shaped body 21, the flange 223 is embedded in the first strip-shaped hole 212 and abuts against the inner wall of the first strip-shaped hole 212. This structure can reduce the noise generated by the first locking portion 121 of the transmission lock block 12 colliding with the side wall of the first strip-shaped hole 212, while also preventing the noise-removing pad 22 from sliding relative to the second rod-shaped body 21.

[0055] In one embodiment of the present invention, the second rod-shaped body 21 has two first fixing holes 213, which are arranged along the length of the second rod-shaped body 21 on the same side of the first strip hole 212. Accordingly, the quick-release transmission device includes two first clamping assemblies 30, and the first clamping pieces 31 in the two first clamping assemblies 30 are assembled to the back surface of the second rod-shaped body 21 via first clamping screws 32 passing through the first fixing holes 213. This structure facilitates adjusting the flatness of the second rod-shaped body 21 on the surface of the sash frame profile 50, for example, ensuring that the front surface of the second rod-shaped body 21 is flush with the surface of the sash frame profile 50.

[0056] like Figure 3As shown, in one embodiment of the present invention, the second rod-shaped body 21 includes a plurality of second fixing holes 214, and the second fixing holes 214 are arranged adjacent to the first fixing holes 213. For example, a second fixing hole 214 is provided on both sides of each first fixing hole 213. Accordingly, the first clamping assembly 30 also includes a protective cover 33. The protective cover 33 includes a plate-shaped body 331 and a second locking portion 332 (for example, the second locking portion 332 may be a staple) located on the lower surface of the plate-shaped body 331. Each protective cover 332 is assembled on the front surface of the second rod-shaped body 21, with the second locking portion 332 locked in the second fixing hole 214. The protective cover 33 prevents the first fixing hole 213 and the first clamping screw 32 from being exposed, protecting the first clamping screw 32 and improving the overall appearance.

[0057] like Figure 6 、 Figure 7 As shown, in one embodiment of the present invention, the quick-release transmission device further includes a transmission box 70, which is connected to the first rod-shaped body 22 and drives the first rod-shaped body 22 to slide within the second C-shaped groove 211. Furthermore, the bottom of the transmission box 70 has a second clamping assembly 71, which includes a second clamping piece and a second clamping screw. The second clamping screw securely engages the second clamping piece, which is embedded in the third C-shaped groove 52, to secure the transmission box 70 to the sash frame profile 50. The remaining structure of the transmission box 70 can be conventionally used in the art and will not be further described here.

[0058] like Figure 8 As shown, in one embodiment of the present invention, the back of the fixed locking point 40 has a third clamping assembly 41. This third clamping assembly 41 includes a third clamping piece and a third clamping screw. The third clamping screw locks the third clamping piece, which is embedded in a C-shaped groove in the door or window frame profile 60, to assemble the fixed locking point to the door or window frame profile 60, facing the quick-release transmission device. Of course, in actual applications, the fixed locking point 40 can also be fixed to the door or window frame profile 60 using other methods, such as directly using screws.

[0059] The utility model also provides a door and window, comprising a sash frame profile and the quick-install transmission device as described above, wherein the sash frame profile is provided with a first C-shaped groove.

[0060] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
