Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0043] Reference Figures 1 to 8 , a door and window accessory system includes: a quick-install transmission rod 100, a door and window accessory 200 and a fastening screw 300.

[0044] The door and window accessories 200 and the quick-install transmission rod 100 are both installed in the accessories installation grooves of the doors and windows.

[0045] Reference Figure 1 and Figure 4 As shown in the figure, the quick-install transmission rod 100 is provided with a connection side, a mounting side and a center plane. The connection side is the upper side of the quick-install transmission rod 100, the mounting side is the lower side of the quick-install transmission rod 100, and the center plane divides the quick-install transmission rod 100 into left and right sides.

[0046] The quick-release transmission rod 100 is provided with an inserting portion 110 and an accessory connecting portion 120 .

[0047] The accessory connecting portion 120 is provided with a limiting surface 112 .

[0048] The inserting portion 110 is disposed on the installation side, and the inserting portion 110 is provided with a avoiding surface 111 and a limiting surface 112 .

[0049] Specifically, in this embodiment, the avoidance surface 111 is configured as an arc surface structure, and the avoidance surface 111 protrudes in a direction away from the central plane.

[0050] The avoidance surface 111 is set to a circular arc surface structure. When the quick-install transmission rod 100 is installed in the accessory installation groove, the circular arc avoidance surface 111 of the quick-install transmission rod 100 is tangent to the bottom surface of the accessory installation groove of the door and window. In the process of turning the angle of the quick-install transmission rod 100, the avoidance surface 111 is used as the rotation point, which can obtain a better installation feel. This can avoid the sharp corner of the insertion part 110 suddenly colliding and rubbing with the bottom surface of the accessory installation groove during rotation, thereby making a loud noise, and also avoid the sharp corner position from hindering the subsequent rotation of the quick-install transmission rod 100.

[0051] In other embodiments, the avoidance surface 111 may also be set as a flat surface structure so that the insertion portion 110 forms a triangular avoidance structure. Those skilled in the art may select the specific structure of the avoidance surface 111 according to actual needs.

[0052] Specifically, in this embodiment, the number of the limiting surfaces 112 disposed on the same side of the central plane is set to three, and the three limiting surfaces 112 are connected in sequence, wherein two limiting surfaces 112 are disposed vertically and the other limiting surface 112 is disposed horizontally. The two vertically disposed limiting surfaces 112 are respectively used to limit the left-right movement of the insertion part 110, while the horizontally disposed limiting surface 112 is used to limit the up-and-down movement of the insertion part 110, so as to prevent the insertion part 110 from being separated from the accessory mounting slot in the up-and-down direction after being installed in the accessory mounting slot.

[0053] The avoidance surface 111 is provided with an outer end and an inner end, the outer end is provided at a side of the inner end close to the connection side, and the inner end is closer to the central plane than the outer end. Specifically, in this embodiment, the avoidance surface 111 is provided as an arc surface structure.

[0054] When installing the quick-release transmission rod, the quick-release transmission rod must be tilted first, and then the insertion portion 110 is inserted into the accessory installation slot. The quick-release transmission rod is then rotated to be flat, and the avoidance surface 111 is provided so that the insertion portion 110 can be smoothly inserted into the accessory installation slot.

[0055] Specifically, in this embodiment, the number of the inserting parts 110 is set to two, and the two inserting parts 110 are symmetrically arranged on both sides of the central plane. In other embodiments, the number of the inserting parts 110 can also be set to only one, and those skilled in the art can select the number of the inserting parts 110 according to actual needs.

[0056] The number of the insertion parts 110 is set to two and they are arranged symmetrically about the central plane, so that after the quick-install transmission rod 100 is installed and before it is connected to the door and window accessories 200, the quick-install transmission rod 100 is not easily separated from the accessory installation groove. In addition, the two insertion parts 110 can play a fool-proof design, so that the quick-install transmission rod 100 can be installed on the left or right side without worrying about the installation master's installation error. When repairing and replacing, the left and right disassembly can also be selected.

[0057] The accessory connection part 120 is arranged on the connection side. Specifically, the accessory connection part 120 is provided with a connection slot 121, the slot of the connection slot 121 faces the connection side. And the slot of the connection slot 121 is provided with a positioning protrusion 122, and the positioning protrusion 122 protrudes toward the inner side of the connection slot 121.

[0058] Specifically, in this embodiment, the number of the locking protrusions 122 is set to two, and the two locking protrusions 122 are symmetrically arranged about the central plane.

[0059] Specifically, in this embodiment, the quick-install transmission rod 100 is further provided with a groove structure 130, the notch of the groove structure 130 is away from the connection side. When working, the groove structure 130 can prevent cement, mortar or foreign matter from getting stuck between the transmission rod and the transmission groove of the door and window profile, ensuring smooth sliding of the transmission rod and eliminating abnormal noise.

[0060] Reference Figure 2 , Figure 3 , Figure 4 The number of the door and window accessories 200 is set to be multiple, and the quick-install transmission rod 100 is set between two adjacent door and window accessories 200.

[0061] Reference Figure 2 and Figure 3 The door and window accessories 200 include conventional door and window accessories 200 such as lock cores, lock points, and corner transmission parts.

[0062] The end of the door and window accessory 200 is provided with a transmission connection part 210. In this embodiment, the transmission connection part 210 is used to connect with the accessory connection part 120, and the transmission connection part 210 is inserted into the connection groove 121 along the first direction.

[0063] Specifically, in this embodiment, the transmission connection part 210 is provided with a locking groove 211, which is used to be plugged and connected with the locking protrusion 122, so as to achieve position restriction of the door and window accessory 200 and the quick-release transmission rod 100, thereby preventing the door and window accessory 200 from accidentally disengaging from the quick-release transmission rod 100.

[0064] Specifically, in this embodiment, the transmission connection portion 210 is further provided with an observation hole 212 , and the locking groove 211 is communicated with the observation hole 212 .

[0065] The fastening screw 300 is threadedly connected to the transmission connection part 210 , and the fastening screw 300 passes through the quick-install transmission rod 100 to achieve relative fixation of the quick-install transmission rod 100 and the door and window accessory 200 .

[0066] Specifically, in this embodiment, the diameter of the fastening screw 300 is smaller than the minimum distance between the two locking protrusions 122 , thereby preventing the locking protrusions 122 from being screwed into the fastening screw 300 and causing damage.

[0067] The processing error of doors and windows plus the installation error, all the accumulated errors, will lead to the difference between the actual installation size and the theoretical installation size. The traditional transmission rod needs to be punched, and the hole size cannot be changed, which will affect the installation and debugging efficiency and the airtightness quality of the window sash. However, the quick-install transmission rod 100 of this design does not need to be punched for installation, and can take into account the window sashes with size problems.

[0068] When the quick-install transmission rod 100 and the door and window fitting 200 are installed, the fastening screw 300 is tightened during the debugging stage so that the end of the fastening screw 300 is tightly pressed against the quick-install transmission rod 100 .

[0069] During debugging, if the operation is not smooth, or the door and window accessories 200 are not reset correctly, use a tool to loosen the fastening screws 300. When the quick-install transmission rod 100 moves relative to the door and window accessories 200, the position of the quick-install transmission rod 100 can be viewed through the observation hole 212 of the accessory to ensure that you know how much the quick-install transmission rod 100 has moved. After moving, tighten the fastening screws 300 so that the end of the fastening screws 300 is pressed against the quick-install transmission rod 100, so that the end of the quick-install transmission rod 100 is relatively fixed to the door and window accessories 200, and then operate the opening and closing. After multiple attempts at debugging, the position of the accessories and the transmission rod can be confirmed.

[0070] After debugging and opening and closing smoothly, tighten the fastening screw 300 with a tool until it is screwed through the quick-release transmission rod 100, so as to ensure that the accessories and the transmission rod will not loosen during daily use.
