DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0021] Please refer to Figure 1 - Figure 8 The utility model provides a technical scheme: a kind of quick -mounting transmission rod, comprising:

[0022] Preparation before installation: Prepare the quick installation transmission rod 100, window frame 200 and hardware fittings 300 of the utility model. Check the transmission rod 100, ensure that the side hole 1002, inclined surface 1003, limiting groove 1010, screwing position 1001, fulcrum 1006, limiting surface 1008, groove 1004, avoidance arc 1007 and other structures are intact. At the same time, confirm that the fixed block 3003, set screw 3004 and observation hole 3002 of the hardware fittings 300 are in good condition. Check the first sliding groove 2001 and second sliding groove on the top surface of the window frame 200, ensure that there is no sundries in the sliding groove, the surface is smooth, and the transmission rod can slide smoothly.

[0023] Installation process: according to the installation requirements of the window frame, select left side installation or right side installation. Take left side installation as an example, align the pair of fulcrums 1006 on the shorter side of the transmission rod 100 with the first sliding groove 2001 on the top surface of the window frame 200, and slowly insert the transmission rod into the first sliding groove 2001. Because the limiting surface 1008 of the transmission rod 100 is designed reasonably opposite to the second sliding groove, during the insertion process, the limiting surface 1008 naturally enters the second sliding groove, and the fulcrum 1006 abuts against the side surface of the first sliding groove 2001. During the insertion process, the groove 1004 on the bottom surface of the transmission rod 100 changes the contact mode from surface contact to line contact, reducing friction and facilitating smooth installation of the transmission rod. The avoidance arc 1007 near the limiting surface 1008 of the transmission rod 100 avoids interference with the window frame slot, ensuring smooth installation of the transmission rod.

[0024] Connection with hardware fittings and debugging: place the hardware fittings 300 into the first sliding groove 2001, align the fixed block 3003 with the limiting groove 1010 on the top surface of the transmission rod 100 and slide it into the limiting groove 1010. Pass the set screw 3004 through the fixed block 3003, so that it is aligned with the screwing position 1001 of the transmission rod 100. During the debugging stage, first tighten the set screw 3004 slightly, so that the hardware fittings 300 are preliminarily connected with the transmission rod 100. If it is found that the door and window are not smooth during operation, or the reset of each fitting is not normal, use a screwdriver to loosen the set screw 3004, and move the hardware fittings 300 horizontally. Observe the position change of the transmission rod 100 through the observation hole 3002 on the top surface of the fixed block 3003, to ensure accurate adjustment of the position of the hardware fittings. Try multiple times until the door and window open and close smoothly, and the reset of each fitting is normal.

[0025] Fastening and daily use: After the adjustment is completed, the tool is used to further tighten the set screw 3004. As the set screw is gradually screwed in, it passes through the screwing position 1001 and abuts against the inclined surface 1003. When the set screw 3004 is about to be screwed through the transmission rod 100, the inclined surface 1003 blocks the set screw from being screwed in further, preventing the set screw from being screwed too much and causing damage to the transmission rod or galling. At this time, the clamped position 1009 of the transmission rod 100 is tightly clamped with the hardware fitting 300, ensuring that the fitting and the transmission rod will not loosen during daily use.
