[0022] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings.

[0023] Embodiment 1

[0024] like Figures 1 to 4 As shown, the utility model provides a gear-driven aluminum alloy fire-resistant window connecting rod wind brace, including a fixing member 1, which is fixed on the aluminum alloy window frame through the connection of a damper 2 and a damping fixing seat 6. The damper 2 is symmetrically arranged at the rear end of the fixing member 1. Four limiting grooves 11 are arranged on the right side of the lower end of the fixing member 1, which are used in conjunction with a latch 31 to limit the displacement of the latch 31 and increase the contact area between the fixing member 1 and the gear short arm 3. The gear short arm 3 is adapted to be arranged in the groove of the limiting groove 11, and the gear short arm 3 is movably connected to the transmission arm 4. The upper end of the transmission arm 4 is fixed to the aluminum alloy fire-resistant window by bolt connection. A support rod 5 is provided between the transmission arm 4 and the fixing part 1. The gear short arm 3, the transmission arm 4 support rod 5 and the fixing part 1 form a four-link wind support, which increases flexibility and also increases the opening angle of the aluminum alloy fire-resistant window. The outer surface of the damper 2 is adapted to connect the damping fixing seat 6, and the two are connected to form a friction damping connector, which prevents the movement of objects by mutual friction, thereby reducing mutual vibration and impact, reducing shaking under external force, and increasing the stability of the overall window.

[0025] Further, if Figure 2As shown, the damping fixing seat 6 includes a main body seat 61, and mounting strips 62 are symmetrically provided at the left and right ends of the main body seat 61. The main body seat 61 is fixed in a specific mounting groove of the aluminum alloy window frame. The mounting strip 62 is provided with mounting holes for easy fixing with bolts, and a damping buckle 63 is provided at the rear end of the main body seat 61, and a force-bearing shaft 64 is provided in the center of the main body seat 61, and the device protrudes vertically from the front end of the main body seat 61. The force-bearing shaft 64 is a hollow structure, and the force-bearing shaft 3 is longer than a conventional damping device, and the force-bearing shaft 3 and the damper 2 can be disassembled quickly.

[0026] Further, if Figure 3 As shown, the rear end of the damper 2 passes through the force-bearing shaft 64 and is adapted to connect to the damping buckle 63. The damping buckle 63 has the function of locking and limiting the force-bearing shaft 64 to limit the rotation angle of the force-bearing shaft 64. A fixing block 65 is provided at the lower end of the outer surface of the force-bearing shaft 64. A damping buckle groove 66 is provided in the middle of the damping buckle 63. Three fixing holes 67 are provided around the damping buckle groove 66. When the connecting rod wind brace needs to be replaced, the fixing block 65 needs to be rotated so that the receiving shaft 64 can be rotated, so that the damper 2 can be disengaged, thereby allowing the connecting rod wind brace to be quickly removed.

[0027] Further, if Figure 3 As shown, a mounting groove 12 is provided at the upper end of the fixing member 1, and a sliding groove 13 is provided at the rear end of the fixing member 1 for limiting the moving position of the fixing shaft 33, a No. 1 rubber pad 14 is provided in the middle of the mounting groove 12 for limiting the left rotation position of the gear short arm 3, and filling the mounting groove 12 to increase the strength, and a No. 2 rubber pad 15 is provided on the left side of the mounting groove 12 to provide filling reinforcement for the mounting groove 12, and its deformation ability also helps to fix the support rod 5.

[0028] Further, if Figure 4 As shown, four latching teeth 31 are evenly distributed on the lower end of the gear short arm 3, and a rotating hole 32 is provided at the lower side of the front and rear surfaces of the gear short arm 3, and a fixed shaft 33 is provided in the rotating hole 32, and the outer surface of the fixed shaft 33 is sleeved in the slide groove 13. When the window is pushed, the gear short arm 3 rotates to drive the latching teeth 31, so that the latching teeth 31 are engaged with the limiting grooves 11 at different positions, thereby increasing the stability of the structure between the gear short arm 3 and the fixing part 1, and reducing the possibility of breakage and damage there. A gasket 34 is provided between the gear short arm 3 and the mounting groove 12, which is a rubber sheet, to reduce the friction and collision between the gear short arm 3 and the mounting groove 12, and also make the connection between the two more stable.

[0029] Further, if Figure 1As shown, threaded holes 51 are symmetrically provided at the upper and lower ends of the support rod 5. The threaded hole 51 at the lower end is fixedly connected to the second rubber pad 15 and the fixing part 1 by bolts, and the threaded hole 51 at the upper end is movably connected to the transmission arm 4 through a limiting shaft. The support rod 5 plays a role of strengthening the support for the transmission arm 4, so that a triangular structure can be formed among the support rod 5, the transmission arm 4, the fixing part 1, and the gear short arm 3, and the structure is stable.

[0030] Working process: first, use bolts to fix the damping fixing seat 6 in the specific installation groove of the aluminum alloy window frame; further, fix the damper 2 on the left and right sides of the rear end of the fixing part 1; further, place gaskets 34 on the front and rear ends of the gear short arm 3, and put them into the installation groove 12 together, and use the fixed shaft 33 to pass through the slide groove 13 and penetrate into the rotating hole 32 to complete the socket connection with the gear short arm 3; further, fix the upper end of the gear short arm 3 to the transmission arm 4 with a polished rod screw and a nut, and fix the middle part of the transmission arm 4 to the support rod 5 with a polished rod screw and a nut; further, put the No. 2 rubber pad 15 on the left side of the installation groove 12, and fix the lower end of the support rod 5 with the fixing part 1 and the No. 2 rubber pad 15 with a polished rod screw and a nut; further, fix the upper end of the transmission arm 4 to the aluminum alloy fire-resistant window with bolts.
