DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 The utility model provides a technical solution: a lifter for an outward-opening bottom-hung window, comprising a window sash 1 and a window frame 2, with a lifter 3 arranged between the window sash 1 and the window frame 2.

[0024] See also Figure 3-7 The lifter 3 includes a pulling rod 31 and a fixing rod 32. The lower end of the pulling rod 31 is fixed with an adjusting block 311 by screws, and the adjusting block 311 is clamped with the lower end of the pulling rod 31 by a rack and a tooth groove. In this way, the screws can be removed and then the position of the adjusting block 311 at the lower end of the pulling rod 31 can be adjusted.

[0025] A connecting block 322 is fixedly installed on the upper end of the fixing rod 32. The fixing rod 32 and the connecting block 322 are arranged in the inner cavity of the window frame 2. A plug-in 315 is clamped on the surface of the pull rod 31. After the plug-in 315 is inserted, it can be flush with the pull rod 31 so that it rests in the inner cavity of the window sash 1, which is convenient for installation and stability.

[0026] The upper end of the pull rod 31 is slidably sleeved with a fixed groove block 312, and a fixed block 314 is fixedly installed on the surface of the fixed groove block 312. The fixed block 314, the pull rod 31 and the fixed groove block 312 are all arranged in the inner cavity of the window sash 1, and an extrusion head 313 is arranged on the surface of the fixed groove block 312. A mounting seat 325 is fixedly installed at the lower end of the fixed rod 32, and a mounting end 323 is integrally extended from the upper end of the mounting seat 325. A paddle 321 is rotatably sleeved on the surface of the mounting end 323 through a pin shaft 324, and a spring piece 326 is arranged between the paddle 321 and the inner cavity of the mounting end 323. The spring piece 326 is U-shaped, and the two ends are respectively abutted against the inner wall of the mounting end 323 and the raised cylinder extending from the surface of the paddle 321. Secondly, the paddle 321 is inclined in its initial state according to the elastic force of the spring piece 326.

[0027] When working, firstly, the fixing rod 32 and the connecting block 322 are slidably sleeved on the corner of the inner cavity of the window frame 2, and then the fixing rod 32 and the connecting block 322 are fixed by screws, and then the pulling rod 31, the fixing slot block 312 and the fixing block 314 are slidably sleeved on the corner of the inner cavity of the window frame 2, and only the fixing block 314 and the fixing slot block 312 are screwed, and then the window sash 1 and the window frame 2 are assembled according to the outward-opening bottom-hung window, and the adjusting block 311 is connected by the connecting rod. When the handle installed on the window sash 1 is turned to open the window sash 1 and push it outward at the same time, at this time, since the external connecting rod is connected to the adjusting block 311, the pulling rod 31 will be driven to extend out of the inner cavity of the window sash 1 and the fixing slot block 312 through the adjusting block 311. The opening and closing angle of the window sash 1 is determined by the sliding length of the pull rod 31. At this time, the extrusion head 313 will come out of the paddle 321, and under the elastic force of the spring 326, the paddle 321 will be driven to return to its original inclined state. When the window sash 1 is closed, the pull rod 31 will be reset, and the extrusion head 313 will follow the window sash 1 into the frame of the window frame 2, and will push the paddle 321 to move to one side and squeeze into the inner cavity of the paddle 321. During the extrusion process, the window sash 1 is slightly lifted and moved upward by the fixed connection with the window sash 1 through the fixed groove block 312, the extrusion head 313 and the fixed block 314. In this way, when the window sash 1 and the window frame 2 are closed, the two can be better fitted together, which can improve the sealing between them and prevent water leakage.
