[0025] When it is needed to open or close the sash, the closing groove group or the opening groove group of the swing arm is respectively clamped with the top beads on the upper surface of the connecting part.

[0026] As a preferred embodiment, the supporting part is provided with a gradual change arc on one side of the insertion groove, the height of the gradual change arc away from the insertion groove is greater than the height of the outer edge of the top of the insertion groove, and the gradual change arc is opposite to the position of the swing groove during the rotation of the swing arm. Through the design of the transition gradual change arc, the swing member can better enter or push out the insertion groove.

[0027] To better support the sash and avoid the second protruding part, the height of the raised part is higher than that of the supporting part, the width of the raised part is smaller than that of the supporting part, the raised part is connected to one side of the rear end of the supporting part, the length direction of the raised part is parallel to the closing groove group, and a transition part is arranged between the raised part and the supporting part.

DETAILED DESCRIPTION

[0045] Referring to Figures 3-5 , the disclosed lower opening and closing mechanism can be applied to the lower frame of a sliding window, and specifically comprises:

[0046] The sliding seat 1 is slidingly connected to the sliding track of the window frame, and is provided with adjacent protruding portions and a connecting portion 11. The height of the connecting portion 11 is lower than that of the protruding portions. The upper portion of the side of the protruding portion close to the connecting portion 11 is provided with a swing groove 121. The swing member 4 is rotationally connected in the swing groove 121 through a second connecting pin 6.

[0047] The lower part of the swing member 4 is smaller than the cross section of the swing groove 121, and can swing left and right in the swing groove 121, and the upper part can extend out of the swing groove 121, and a socket is arranged on the upper part, and the second connecting pin 6 is rotatably connected to the lower part of the swing groove 121 away from the connecting part 11.

[0048] The swing arm 2 comprises a supporting part 21 and a lifting part 22 connected to each other, the supporting part 21 is rotatably connected to the connecting part 11 of the sliding seat 1 through the first connecting pin 5 at the end away from the lifting part 22, and an insertion slot 211 is arranged on the outer wall and is arranged penetratingly upwards and outwards, and the insertion slot 211 can be rotated to be aligned with the swing groove 121.

[0049] The specific position of the insertion slot 211 is that when the swing arm 2 is driven by the sash to rotate to the opening angle, the insertion slot 211 can be aligned with the swing groove 121 as the design standard.

[0050] The transposition member 3 is arranged on one side of the sliding seat 1, and comprises a mounting seat 31 and a plug 32, the mounting seat 31 is fixed on one side of the sliding track at the bottom of the window frame, the plug 32 protrudes forward and is arranged on the sliding path of the sliding seat 1, and can drive the swing member 4 to enter / exit the insertion slot 211 from the swing groove 121 when the sliding seat 1 slides. The swing groove 121 has a rotating space for the swing member 4, and can accommodate the end of the swing member 4 close to the connecting part 11 to rotate below the lower surface of the plug 32.

[0051] Participation Figures 1-4 When the sash is ready to be opened, the sash is first pulled to drive the swing arm 2 to rotate to the opening angle, so that the insertion slot 211 is aligned with the swing groove 121, at this time the plug 32 is located in the socket, and with the movement of the sliding seat 1, the end of the swing member 4 close to the connecting part 11 is driven by the plug 32 to rotate into the insertion slot 211, so as to lock the swing arm 2 and prevent it from rotating, thereby preventing the position from changing during the movement of the sash.

[0052] In addition, before the sash drives the swing arm 2 to rotate to the opening angle, the plug 32 is located in the socket, and the sliding seat 1 cannot move by itself, and only when the insertion slot 211 is rotated to be aligned with the swing groove 121 can the sliding seat 1 move, thereby achieving opening positioning and preventing the phenomenon of sliding and opening at the same time.

[0053] When the sash moves to the closed position, the end of the inclined swing member 4 away from the connecting part 11 is in contact with the fixed transposition member 3, and with the continuous movement of the sliding seat 1, the swing member 4 is limited by the plug 32 to rotate away from the connecting part 11, and the part of the swing member 4 entering the insertion slot 211 rotates out of the insertion slot 211, thereby releasing the locking of the swing arm 2, and with the continuous pulling and sliding movement of the sash, the swing member 4 abuts against the inner side of the swing groove 121, and the sash rotates to be closed.

[0054] In addition, the socket part surrounds the plug 32 on both sides after the swing member 4 is turned out of the slot 211, so that the swing member 4 cannot be turned left and right, and thus the transposition member 3 locks the sliding seat 1, achieving closing positioning and preventing the sliding seat 1 from moving randomly when the window is closed.

[0055] Through opening positioning and closing positioning, the sash can only reach the predetermined position to perform the opening or closing action, eliminating the possibility of collision with the vertical stay 7 or the locking piece. At the same time, the elastic sudden rotation is changed to slow rotation without spring, better protecting the window.

[0056] Referring to Figure 6 and Figure 7 , the sliding seat 1 is long strip-shaped as a whole, and the two sides are vertical surfaces adapted to the slide to facilitate sliding in the slide.

[0057] The sliding seat 1 includes two protruding parts, namely a first protruding part 12 and a second protruding part 13, and a connecting part 11 is located between the two protruding parts.

[0058] The first protruding part 12 is longer than the second protruding part 13, and the first protruding part 12 is provided with a swing groove 121 which penetrates the top of the first protruding part 12 and the side towards the connecting part 11.

[0059] Regarding the design of the swing groove 121, the end of the swing groove 121 away from the connecting part 11 is a vertical surface, and the bottom is an inclined surface, and the height of the end of the inclined surface is greater than the height of the bottom end of the swing groove 121, as shown in Figure 5 .

[0060] The structure adapted to the swing groove 121 is that the lower part of the swing member 4 is a right triangle shape, with the long straight angle side upward and the short straight angle side inside, and of course, the bottom is provided with a rounded corner to eliminate sharp parts, and the inclined side is located on one side of the inclined surface of the swing groove 121.

[0061] As a preferred solution, when the swing member 4 is turned to the short straight angle side abutting the inner wall of the swing groove 121, the lower part height is the same as the height of the supporting part 21 of the swing arm 2, without affecting the swing arm turning to open.

[0062] To better limit the turning angle of the swing arm 2, the connecting part 11 is provided with a top bead 111 on both sides of the first connecting pin 5, and the lower part of the top bead 111 is provided with a spring 112 to support, and the top bead 111 can be a steel ball with the exposed part not more than half.
