[0043] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention.

[0044] The utility model also has the following implementation methods based on the above:

[0045] In a further embodiment of the utility model, a transmission bar 12 is slidably installed in a U-groove 21 of a door and window profile 2, a transmission cover plate 11 is installed in a notch of the U-groove 21, a cover plate slide groove 115 is provided on the transmission cover plate 11, a tension spring 14 is located in the cover plate slide groove 115, a locking point 13 is located above the transmission cover plate 11, and a transmission bar 12 is located below the transmission cover plate 11. The locking point 13 and the transmission bar 12 are connected by a tension spring 14, and the tension spring 14 is always in a tensioned state. The locking point 13 always rests against the upper surface of the transmission cover plate 11. When the transmission bar 12 slides in the U-groove 21, the tension spring 14 can be driven to slide in the cover plate slide groove 115, thereby driving the locking point 13 to slide along the cover plate slide groove 115, thereby realizing the locking, horizontal opening and suspended opening functions of the door and window fan body.

[0046] In a further embodiment of the present invention, Figure 1 The figure shows an embodiment of the sunken locking point structure in the horizontally opened state. Figure 8 The figure shows an embodiment of the sunken locking point structure in the locked state. When the window is converted from the locked state to the flat open state, the handle is rotated forward to drive the transmission bar 12 in the U groove 21. Figure 8 Move the displayed position to Figure 1 In the position shown, during the movement, the locking point 13 climbs from above the middle part 112 of the cover along the cover connecting part 113 to above the end part 111 of the cover, and the tension spring 14 stretches and becomes longer.

[0047] In a further embodiment of the present invention, when the window is converted from the flat open state to the locked state, the handle is rotated in the reverse direction to drive the transmission bar 12 in the U groove 21. Figure 1 Move the displayed position to Figure 8 In the position shown, during the movement, the locking point 13 moves from above the cover end 111 along the cover connection portion 113 to above the middle portion 112 of the cover, and the tension spring 14 contracts to pull the locking point 13 to be hidden in the U groove 21. At this time, the tension spring 14 is still in a stretched state.

[0048] In a further embodiment of the present invention, Figure 10 The figure shows an embodiment of the sunken locking point structure in the hanging state. When the window is converted from the flat open state to the hanging state, the handle is rotated in the reverse direction to drive the transmission bar 12 in the U groove 21. Figure 1 Move the displayed position to Figure 10At the shown position, during the movement, the locking point 13 climbs from above the middle part 112 of the cover plate along the connecting part 113 of the cover plate to above the end part 111 of the cover plate, and the tension spring 14 stretches and becomes longer.

[0049] In a further embodiment of the present utility model, when the window form is converted from the casement-down state to the casement-open state, turn the handle forward to drive the transmission bar 12 in the U-shaped groove 21 from Figure 10 the shown position to Figure 1 the shown position. During the movement, the locking point 13 moves downward from above the end part 111 of the cover plate along the connecting part 113 of the cover plate to above the middle part 112 of the cover plate, and the tension spring 14 contracts to pull the locking point 13 to hide in the U-shaped groove 21. At this time, the tension spring 14 is still in a stretched state.

[0050] In a further embodiment of the present utility model, different from the tight connection between the locking point and the transmission bar in the general window and door U-shaped groove hardware, in this structure, the locking point 13 and the transmission bar 12 are connected by a spring 14, and the transmission cover plate 11 adopts a sunken slide rail design.

[0051] In a further embodiment of the present utility model, when the window and door are in the locked state, the plane slide rail of the transmission cover plate 11 cooperates with the stretched state of the spring 14 to make the locking point 13 completely expose outside the window and door profile 2, and cooperate with the lock block to achieve the locking purpose.

[0052] In a further embodiment of the present utility model, when the window and door are changed from the locked state to the open state, the transmission bar 12 moves along the axial direction of the window and door profile 2. The sunken slide rail of the transmission cover plate 11 cooperates with the contraction process of the spring 14 to make the locking point 13 move downward in the direction of the groove of the window and door profile 2 accordingly. At this time, all the locking points 13 on the window sash are hidden inside the window and door profile 2.

[0053] In a further embodiment of the present utility model, when the window and door are changed from the open state to the casement-down state, the transmission bar 12 continues to move along the axial direction of the window and door profile 2. The rising slide rail of the transmission cover plate 11 cooperates with the stretching process of the spring 14 to make the locking point 13 move upward in the direction outside the groove of the window and door profile 2 accordingly until it completely exposes outside the window and door profile 2, and cooperate with the lock block to achieve the casement-down purpose.

[0054] In a further embodiment of the present utility model, the overall structure of the sunken locking point structure is beautiful. When the window and door are in the casement-open state, the locking point 13 is completely hidden inside the window and door profile 2, avoiding collisions with users and achieving an anti-collision effect.

[0055] In a further embodiment of the present utility model, the overall structure of the sunken locking point structure is simple, suitable for U-shaped groove hardware, with high adaptability, and can be used in various window and door structures adopting U-shaped groove hardware.

[0056] In a further embodiment of the present utility model, by means of a reversible handle, the transmission bar 12 slides back and forth within the door and window profile 2, enabling the realization of three functions: locking, inward opening, and outward opening. Different functions can also be achieved according to different types of doors and windows.

[0057] The above are only preferred embodiments of the present utility model, and do not limit the implementation manners and protection scope of the present utility model accordingly. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the content of the specification and drawings of the present utility model should be included within the protection scope of the present utility model.
