Description

Technical Field

[0001] The invention belongs to the technical field of building doors and windows, and in particular to a hardware structure for a casement-tilt window and a working method thereof. Background Art

[0002] The hardware structure for casement and tilt windows in the prior art also has the following defects:

[0003] (1) When the window is closed, the overlap between the sash and the frame is usually about 6 mm. Although there is a sealing strip, the overlap also directly affects the sealing of the door and window after closing.

[0004] (2) Most of the connections between the various components are made by screws. After a long period of use, the screws will inevitably become loose, causing malfunctions during use of the doors and windows, resulting in high maintenance costs in the future.

[0005] (3) When tilting the hinge inward, the connection structure at the hinge is usually divided into two structures. One structure is the exposed hinge tilting inward. When installing the hinge, the sealing strip needs to be cut off, resulting in poor sealing; poor energy saving effect; interference with other construction processes; and poor aesthetics; the other is the hinge stacking type tilting inward. Although it realizes hidden installation, there is no shaft structure. When tilting inward, the hinge stacking is used for a long time and needs to bear the gravity of the door, resulting in noise during use, uncomfortable use, door falling, poor sealing and other problems. In addition, when the stacking bites inward, it is tilted inward in a "hard-separated" manner, which reduces the service life of the hinge stacking;

[0006] In summary, the hardware structure for casement-tilt windows in the prior art still has many technical defects. Summary of the invention

[0031] Beneficial effects of the present invention:

[0032] (1) In the hardware structure of the present invention, the structural components are installed by means of clamping ribs or inlays, which is firmly installed and avoids future maintenance, thereby reducing maintenance costs;

[0033] (2) Rollers are installed on the upper lock column and the lower lock column respectively, and when they are engaged with the locking point, the operation is smooth and there is no wear;

[0034] (3) The installation position of the lock column is the edge of the locking block, so that after the window sash is locked, the overlap between the frame and the sash reaches 9 mm, thereby improving the sealing performance of the window; the protrusion is increased from 8 mm in the prior art to 12 mm, which improves the aesthetics of the window sash; and the profile surface is chamfered, which is more beautiful;

[0035] (4) The lower hinge seat and the hinge support adopt the method of matching the pin shaft and the pin hole, which has good load-bearing capacity. When tilting inward, it is convenient and smooth to operate without wear, and at the same time prolongs the service life of the window; and the other end of the hinge support is fixed to one end of the wind support, which effectively prevents the profile from being damaged by excessive force during the opening and closing process of the sash, and fully protects the profile;

[0036] (5) Anti-drop blocks are installed at the corners of the fan. The installation and use of anti-drop blocks make the closing and opening of the fan smooth, improve product quality, and extend the service life of the fan;

[0037] (6) When the door sash is in the tilted state, the limit spring installed at the second angle sensor limits the pull rod pin at the pull rod extension position to keep the tilted state stable; when the door sash is turned from the tilted state to the horizontal open or locked state, the reset rod assists the pull rod to return to its original position to ensure the stability of the return process and the fixed position; at the same time, the limit spring and the reset rod ensure stable and smooth operation when switching between the tilted and non-tilted states;

[0038] (7) The safety fork and the safety groove are used together to prevent misoperation when the handle is in the inward or open state, which may cause confusion in the transmission system;

[0039] (8) Both the first angle sensor and the second angle sensor are integrally formed structures, which improves installation accuracy and enhances the appearance of the profile after installation, thereby enhancing market competitiveness. BRIEF DESCRIPTION OF THE DRAWINGS
