DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. 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 those skilled in the art without creative work are 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 fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interactively 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 slots of the doors and windows.

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

[0046] The quick-release transmission rod 100 includes 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 provided on the installation side, and the inserting portion 110 is provided with a position-avoiding surface 111 and a position-limiting surface 112 .

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

[0050] The avoidance surface 111 is configured as a circular arc surface structure. When the quick-install transmission rod 100 is installed in the accessory installation slot, the arc avoidance surface 111 of the quick-install transmission rod 100 is tangent to the bottom surface of the accessory installation slot of the door or window. During the rotation process of the quick-install transmission rod 100, the avoidance surface 111 is used as the rotation point, which can achieve a better installation feel. This can prevent the sharp corners of the insertion portion 110 from suddenly colliding and rubbing with the bottom surface of the accessory installation slot during rotation, thereby generating loud noise. It also prevents the sharp corners 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, three limiting surfaces 112 are provided on the same side of the central plane. The three limiting surfaces 112 are connected in sequence, with two limiting surfaces 112 provided vertically and one limiting surface 112 provided horizontally. The two vertical limiting surfaces 112 are respectively used to limit the left-right movement of the insertion portion 110, while the horizontal limiting surface 112 is used to limit the vertical movement of the insertion portion 110, thereby preventing the insertion portion 110 from being separated from the accessory mounting slot in the vertical direction after being installed in the accessory mounting slot.

[0053] The avoidance surface 111 is provided with an outer end and an inner end, wherein the outer end is provided on a side of the inner end close to the connection side, and the inner end is closer to the center plane than the outer end. Specifically, in this embodiment, the avoidance surface 111 is provided with 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 insertion portions 110 is set to two, and the two insertion portions 110 are symmetrically arranged on both sides of the central plane. In other embodiments, the number of the insertion portion 110 can also be set to only one, and those skilled in the art can select the number of the insertion portions 110 according to actual needs.

[0056] The two insertion portions 110 are arranged symmetrically about the central plane. This ensures that after the quick-release transmission rod 100 is installed and before it is connected to the door and window accessory 200, it is difficult to separate from the accessory mounting slot. Furthermore, the two insertion portions 110 provide a fool-proof design, allowing the quick-release transmission rod 100 to be installed on either the left or right side, eliminating the worry of the installer making an error. During maintenance or replacement, both left and right disassembly options are also available.

[0057] The accessory connection portion 120 is provided on the connection side. Specifically, the accessory connection portion 120 defines a connection slot 121, the opening of which faces the connection side. Furthermore, the opening of the connection slot 121 is provided with a retaining protrusion 122, which protrudes inwardly from 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-release drive rod 100 is further provided with a groove structure 130, the notch of which faces away from the connection side. During operation, the groove structure 130 prevents cement, mortar, or foreign matter from becoming stuck between the drive rod and the drive groove of the door and window profile, ensuring smooth sliding of the drive 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 portion 210. In this embodiment, the transmission connection portion 210 is used to connect with the accessory connection portion 120, and the transmission connection portion 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 into and connected with the locking protrusion 122, thereby achieving position restriction of the door and window accessories 200 and the quick-release transmission rod 100, thereby preventing the door and window accessories 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 portion 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 damaged by the screwing-in of the fastening screw 300 .

[0067] The cumulative errors in door and window manufacturing and installation can lead to discrepancies between the actual and theoretical dimensions. Traditional drive rods require drilling, and the hole size cannot be modified, which impacts installation and commissioning efficiency and the airtightness of the window sash. However, the quick-install drive rod 100 designed in this paper requires no drilling and can accommodate window sashes with size issues.

[0068] When the quick-install transmission rod 100 and the door and window accessory 200 are installed, the fastening screw 300 is tightened during the debugging phase until 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 checked 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. Then operate the opening and closing. After multiple attempts at debugging, you can confirm the position of the accessories and the transmission rod.

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

[0071] Door and window accessories system installation method, refer to Figures 7 to 10 , including the following steps:
