With further reference to fig. 2-4, the principle of action of the present slide 1 is as follows:
When the window sash 3 is closed in the window frame 2, the first end 31 is clamped with the unlocking component 40, and the sliding frame 10 is limited at the initial position in the sliding rail of the window frame 2 and cannot move; at this time, one end of the swing arm assembly 20 may be rotated to push out the window sash 3;
Before the window sash 3 is pushed out of the window frame 2 and is not opened to the maximum angle, the second end 32 is kept in contact with one end of the swing arm assembly 20, so that the first end 31 is stably clamped with the unlocking assembly 40, and the sliding frame 10 is still limited at the initial position in the sliding rail of the window frame 2 and cannot move;
When the window sash 3 is opened to a maximum angle, the second end 32 is separated from one end of the swing arm assembly 20, and the self-locking assembly 30 is driven by the autorotation acting force to rotate until the third end 33 is abutted to one end of the swing arm assembly 20, so that one end of the swing arm assembly 20 is self-locked and cannot rotate; simultaneously, the self-locking assembly 30 rotates to enable the first end 31 to be separated from the unlocking assembly 40, and the sliding frame 10 is in an initial position and can slide in the sliding rail of the window frame 2;
After the sliding frame 10 drives the window sash 3 to horizontally slide out of the initial position, the swing arm assembly 20 keeps self-locking all the time under the supporting acting force of the self-locking assembly 30, and the window sash 3 cannot be pushed out or pulled in;
When the sliding frame 10 translates and slides back to the initial position again, the unlocking component 40 contacts with the first end 31 of the self-locking component 30, under the action force of the window sash 3, the unlocking component 40 applies a reaction force to the self-locking component 30, so that the self-locking component 30 reversely rotates until the second end 32 contacts with one end of the swing arm component 20 of the unlocking component 40, the limiting of the sliding frame 10 is realized, and one end of the swing arm component 20 can be pulled into the window sash 3 in a rotatable mode so as to close the window sash 3 into the window frame 2.
The sliding device 1 in the scheme acts on the transmission connection position of the window sash 3 and the window frame 2, can limit the translation of the window sash 3 when the window sash 3 is pushed open, and the self-locking swing arm assembly 20 prevents the window sash 3 from swinging when the window sash 3 translates, so that the smoothness of the window sash 3 in the opening and closing process is improved.
