An adjusting groove 421e is formed between the two second mounting holes 421a on the second mounting seat 421, and an opening is formed in one side of the adjusting groove 421e outside the window, so that the adjusting block 422 can be mounted conveniently. One side of the window of the adjusting groove 421e is connected to the engaging opening 421d, so that the engaging head 422a described below can enter the engaging opening 421d after the adjusting block 422 enters the adjusting groove 421 e. The bottom surface of the adjusting groove 421e is flush with the bottom surface of the second fixing strip 421b protruding from the top toward the window outer side, so that the adjusting block 422 is smoothly installed in the adjusting groove 421e without being affected by the second installation groove 21 after the second installation seat 421 is installed. A circular blind hole-shaped regulation hole 421f is provided at a bottom center position of the regulation groove 421e, and is used for fitting an eccentric head 423c described below.

The adjusting block 422 is a block-shaped part matched with the adjusting groove 421e, one end of the window of the adjusting block 422 is provided with a clamping head 422a, the top of the adjusting block 422 is provided with an oval adjusting port 422b, and an oval through hole is arranged in the adjusting port 422 b. The eccentric nail 423 is composed of a cylindrical nail head 423a and a nail body 423b, the radius of the nail head 423a is larger than that of the nail body 423b, and the radius of the nail body 423b is the same as the radius of the through hole in the adjusting port 422 b. The nail body 423b is provided with an eccentric head 423c at the bottom, and the eccentric head 423c is inserted into the adjusting hole 421f and is closely riveted with the bottom of the adjusting hole 421 f. During installation, the adjusting block 422 is pushed along the adjusting groove 421e, the clamping head 422a enters the clamping opening 421d, the eccentric nail 423 penetrates through the adjusting opening 422b to insert the eccentric head 423c into the adjusting hole 421f for riveting, meanwhile, the nail body 423b enters the through hole in the adjusting opening 422b, and the nail body 423b can push the adjusting block 422 to move along the adjusting groove 421e by rotating the eccentric nail 423. After the installation, the top of the adjusting block 422, the top of the fastening opening 421d and the top of the protrusion 421C form an inverted C-shaped arc contact surface 424 with a high outside of the window and a low inside of the window.

With the above structure, when the window sash 1 is closed, the locking head 412 gradually embraces the contact surface 424 formed by the adjusting block 422, the engaging opening 421d and the protruding portion 421c as the window sash 1 is gradually closed. The outer end of the locking head 412 slides along the outer side of the contact surface 424, and the locking head 412 is driven to rotate, so that the inner end of the locking head 412 abuts against the inner side of the contact surface 424. In the process, since the contact surface 424 is higher at the outer side of the window, after the window sash 1 is closed, the outer end of the locking head 412 is raised along the contact surface 424, and the pressing force is applied to the connecting shaft 423 and the supporting portion 411c thereof by using the inner end of the locking head 412 as a fulcrum under the lever action. And then the contact between the movable end 41 and the fixed end 42 is tighter after the window sash 1 is closed, thereby improving the tightness between the window sash 1 and the window frame 2 and realizing the locking of the window sash 1. Meanwhile, since the contact surface 424 is higher at the outer side of the window, the opening direction of the locking head 412 is slightly outward of the window after the window sash 1 is closed, so that the pressing force applied to the connecting shaft 423 is slightly inward of the window, and the window sash obtains a force inward of the window, which is helpful for locking the window sash 1.

When the window sash 1 is opened, one end of the locking head 412 slides on the contact surface 424, and the locking head 412 is driven to rotate, and when the locking head 412 is separated from the contact surface 424, the opening of the locking head 412 faces the contact surface 424, so that the window sash 1 can be closed next time.

In addition, the position of the adjusting block 422 on the second mounting seat 421 can be adjusted by rotating the eccentric pin 423. When the adjusting block 422 moves outwards along the adjusting groove 421e, the window sash 1 is closed, and the outer end of the locking head 412 is raised higher along the contact surface 424 after the adjusting block 422 moves outwards. In this way, the tightness of the sash 1 and the frame 2 may be increased, whereas the tightness of the sash 1 and the frame 2 may be decreased.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
