[0035] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] The quick-install transmission rod of the utility model is used to be installed in the C-shaped groove of the door and window frame, and is combined with a transmission device, a handle, etc. to realize the locking of the door and window. Figure 2 As shown, the C-shaped groove 30 of the door and window frame includes a groove, a bottom wall 31, two groove walls 32 and two groove opening walls 33, wherein the two groove walls 32 are respectively connected to the bottom wall 31, and the two groove opening walls 33 are respectively located on both sides of the groove, that is, the C-shaped groove 30 is located in the semi-enclosed area of ​​the bottom wall 31, the two groove walls 32 and the two groove opening walls 33, and the spacing W11 of the two groove opening walls 33 is smaller than the spacing W12 of the two groove walls 32. The bottom wall 31, the two groove walls 32 and the two groove opening walls 33 can be respectively planar. In practical applications, one or more of the bottom wall 31, the two groove walls 32 and the two groove opening walls 33 can be in an arc shape. In particular, the two groove opening walls 33 can also be in a straight line shape (that is, the height of the groove walls 33 is extremely small).

[0037] like Figure 1 , which is a schematic diagram of a quick-release transmission rod provided by an embodiment of the utility model. The quick-release transmission rod of this embodiment includes a metal rod 10 and a plurality of clamping blocks 20. Similar to the existing transmission rod, the metal rod 10 can be made of aluminum alloy, stainless steel and other materials and is in a flat strip shape, and can have a plurality of locking points thereon (the locking points can cooperate with the locking structure on the door frame or window frame to achieve door and window locking). The metal rod 10 can be installed into the C-shaped groove 30 with the cooperation of the clamping block 20, and can slide along the length direction X in the C-shaped groove 30 under the drive of the transmission, so that the locking points are clamped into the corresponding locking structure of the door frame or window frame.

[0038] Combination Figure 3 , Figure 4As shown, the metal rod 10 comprises a main body 11 and a strip-shaped protrusion 12, wherein the strip-shaped protrusion 12 is located on the upper surface of the main body 11 and is arranged along the length direction of the metal rod 10. It can be understood that the width of the strip-shaped protrusion 12 is smaller than the width of the main body 11, and the two side edges of the strip-shaped protrusion 12 are respectively located on the inner side of the two side edges of the main body 11. The main body 11 comprises two first vertical side walls 111 respectively perpendicular to the width direction Y, and correspondingly, the strip-shaped protrusion 12 comprises two second vertical side walls 121 respectively perpendicular to the width direction Y. The height of the main body 11 (i.e., the dimension perpendicular to the XY plane) is matched with the height of the groove wall 32 (e.g., the height of the main body 11 is slightly smaller than the height of the groove wall 32), the spacing W22 between the two first vertical side walls 111 is larger than the width of the groove of the C-shaped groove 30 (i.e., the spacing W11 between the two groove walls 33), the spacing W21 between the two second vertical side walls 121 is smaller than the width of the groove of the C-shaped groove 30, and the spacing W23 between any second vertical side wall 121 and the first vertical side wall 111 facing away (i.e., the first vertical side wall 111 farther away) is smaller than the spacing between the groove wall 33 adjacent to the second vertical side wall 121 in the C-shaped groove 30 and the opposite groove wall 32 (i.e., the groove wall farther away). Similarly, the first vertical side wall 111 and the second vertical side wall 121 are not limited to planes, and may also be micro-arc surfaces, etc.

[0039] The block 20 can be made of relatively low hardness plastic, resin and other materials, so that it can be deformed to a certain extent by extrusion and other methods. Each block 20 includes two parallel card parts 21, and the distance W31 between the inner surfaces of the two card parts 21 is adapted to the distance W21 between the two second vertical side walls 121 on the metal rod 10 (for example, W31 is slightly larger than W21), and the distance between the outer surfaces of the two card parts 21 is adapted to the width W11 of the notch of the C-shaped groove 30 (for example, W32 is slightly smaller than or equal to W11). In particular, the thickness of the two card parts 21 (that is, the dimension along the width direction Y) can be equal.

[0040] In this way, Figure 6As shown, when the metal rod 10 is installed in the C-shaped groove 30, one side of the main body 11 can be first installed in the C-shaped groove 30 through the notch of the C-shaped groove 30, until one of the second vertical side walls 121 of the strip-shaped protrusion 12 is in contact with the corresponding notch wall 33. At this time, the other side of the main body 11 can also be installed in the C-shaped groove 30 through the notch. After the lower surface of the main body 11 is in contact with the bottom wall 31 of the C-shaped groove 30, the main body 11 can be moved along the width direction Y so that the strip-shaped protrusion 12 is located at the center of the width direction of the notch of the C-shaped groove 30. Then, the clamping block 20 is installed in the C-shaped groove 30 so that the two clamping plate parts 21 are respectively embedded between the second vertical side wall of the strip-shaped protrusion 12 and the notch wall 33 of the C-shaped groove 30 to prevent the metal rod 10 from moving in the width direction Y and prevent the metal rod 10 from escaping from the C-shaped groove 30. Figure 7 In particular, to facilitate the metal rod 10 to be inserted into the C-shaped groove 30 , the bottoms of the first vertical side wall 111 and the second vertical side wall 121 of the main body 11 may have arc-shaped chamfers.

[0041] The above-mentioned quick-release transmission rod makes the distance between one of the second vertical side walls 121 on the metal rod 10 and the first vertical side wall 111 opposite thereto smaller than the distance between the slot wall 33 adjacent to the second vertical side wall 121 in the C-shaped slot 30 and the opposite slot wall 32, so that the metal rod 10 can be obliquely inserted into the C-shaped slot 30, and then the two clamping plate parts 21 of the clamping block 20 limit its movement in the width direction to prevent it from escaping from the C-shaped slot 30, which greatly facilitates the assembly and subsequent maintenance of the transmission rod.

[0042] Combination Figure 3 , Figure 5 As shown, in one embodiment of the utility model, each card block 20 includes a connecting portion 22, two card plate portions 21 are respectively vertically connected to the lower surface of the connecting portion 22 (for example, the card plate portion 21 and the connecting portion 22 can be integrally formed by injection molding), and a evacuation space 25 adapted to the size of the strip-shaped protrusion 12 is formed below the connecting portion 22 (that is, the evacuation space 25 is located between the inner side surfaces of the two card plate portions 21). Through the above structure, the two card plate portions 21 can be simultaneously embedded between the notch wall 33 of the C-shaped groove 30 and the second vertical side wall 121 of the strip-shaped protrusion 12, which facilitates the assembly of the card block 20. Of course, in actual applications, the two card plate portions 21 can also adopt a split structure, but this will make the assembly of the card block 20 more complicated.

[0043] In one embodiment of the utility model, the outer surfaces of the two clamping plate parts 21 are respectively flush with the outer edges (edges perpendicular to the width direction) of the connecting part 22. Accordingly, the metal rod 10 includes a buckle hole 13, and the lower surface of the connecting part 22 of the clamping block 20 has a buckle adapted to the buckle hole 13. The clamping block 20 is fixed on the metal rod 10 by the buckle and the buckle hole 13, and when the clamping block 20 is fixed to the metal rod 10, the inner surfaces of the two clamping plate parts 21 are respectively attached to the two second vertical side walls 121 of the strip-shaped protrusion 12. In this way, when the metal rod 10 is placed in the C-shaped groove 30, the assembly can be achieved by fixing the clamping block 20 to the metal rod 10, and during the sliding process of the metal rod 10, the clamping block 20 slides with the metal rod 10. Of course, in actual application, the clamping block 20 can also be fixed on the door and window frame (i.e., both sides of the C-shaped groove 30), but this requires processing the fixing position on the door and window frame, and the operation is relatively cumbersome.

[0044] In order to facilitate the fixing of the block 20 to the metal rod 10, in one embodiment of the utility model, the lower surface of the main body 11 of the metal rod 10 has a strip-shaped through groove 14, that is, the cross section of the metal rod 10 is in the shape of a "J". The above-mentioned buckle hole 13 vertically penetrates from the upper surface of the strip-shaped protrusion 12 into the strip-shaped through groove 14. There are two elastic arms 23 in the avoidance space 25 below the connecting portion 22 of the block 20. The two elastic arms 23 are respectively vertically connected to the lower surface of the connecting portion 22 (the two elastic arms 23 can be integrally injection molded with the connecting portion 22). The outer side surface of the free end of each elastic arm 23 has a hook 24, and when the block 20 is fixed to the metal rod 10, the two elastic arms 23 respectively pass through the buckle hole 13 and the two hooks 24 hook the bottom wall of the strip-shaped through groove 14.

[0045] It can be understood that in order to prevent the block 20 from moving in the button hole 13, the distance between the two elastic arms 23 is adapted to the size of the button hole 13. The structure of the button hole 13 and the two elastic arms 23 facilitates the assembly of the block 20 to the metal rod 10, and also facilitates the disassembly of the block 20, for example, the elastic arms 23 can be directly cut off. In practical applications, the elastic arms and claw structures in the block 20 can also be replaced by other existing structures, as long as the block 20 can be fixed on the metal rod 10.

[0046] like Figure 5As shown, in one embodiment of the utility model, a stopper 26 is further provided in the avoidance space 25 below the connection portion 22 of the block 20, for example, the stopper 26 can be located between the two elastic arms 23. The size of the two side walls of the stopper 26 perpendicular to the deformation direction of the elastic arms 23 is adapted to the size of the corresponding inner side wall in the button hole 13 (for example, equal to or slightly smaller than the size of the corresponding inner side wall in the button hole 13). For example, when the two elastic arms 23 can be deformed perpendicular to the width direction Y, the two side walls of the stopper 26 perpendicular to the length direction X are adapted to the size of the corresponding inner side wall in the button hole 13, so that when the block 20 is assembled to the metal rod 10, the two elastic arms 23 can prevent the block 20 from moving relative to the metal rod 10 in the width direction Y, and the stopper 26 can prevent the block 20 from moving relative to the metal rod 10 in the length direction X.

[0047] like Figure 2 As shown, in one embodiment of the present invention, in the C-shaped groove 30, the distance W14 between each groove wall 32 and the adjacent groove wall 33 is equal to the distance between another groove wall 32 and the adjacent groove wall 33, that is, the C-shaped groove 30 has a symmetrical structure. Figure 3 As shown, on the metal rod 10, the distance W24 between each first vertical side wall 111 and the adjacent second vertical side wall 121 is equal to the distance between another first vertical side wall and the adjacent second vertical side wall. This structure facilitates the metal rod 10 to be obliquely installed into the C-shaped groove 30 from any side.

[0048] In particular, the distance W24 between the first vertical side wall 111 and the adjacent second vertical side wall 121 is smaller than the distance between the groove wall 32 of the C-shaped groove 30 and the adjacent notch wall 33. This makes it easier for the metal rod 10 to be obliquely installed in the C-shaped groove 30.

[0049] In one embodiment of the utility model, on the metal rod 10, the height of the strip-shaped protrusion 12 protruding from the main body 11 is adapted to the height of the slot wall 33, so that when the metal rod 10 is installed in the C-shaped slot 30, the upper surface of the metal rod 10 is basically flush with the slot edge of the C-shaped slot 30.

[0050] The utility model also provides a door and window transmission assembly, including a transmission device and the quick-install transmission rod as described above, wherein the transmission device can adopt any existing structure, and the transmission device is connected to the metal rod in a transmission manner, thereby driving the metal rod to slide in the C-shaped groove of the door and window frame.

[0051] The utility model also provides a door and window structure, including a door and window frame and the door and window transmission assembly as described above, the door and window frame includes a C-shaped groove, and the metal rod of the door and window transmission assembly is installed in the C-shaped groove, the clamping block is fixed on the metal rod and the two clamping plate parts are respectively clamped between the second vertical side wall of the metal rod and the adjacent slot wall.

[0052] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
