In one embodiment, a method for using a multifunctional window for a building specifically includes the following steps:

Step S101: firstly, fixedly mounting an aluminum frame at a position of a building where a window is required to be mounted;

step S102: then, when the window is required to be opened, only the first window frame is required to be rotated, and the first window frame can be folded and slid in the aluminum frame through the arrangement of the hinge plates and the sliding blocks, so that the space in the aluminum frame can be opened, and ventilation is performed;

step S103: if only the second window frame is required to be pushed to be opened, only the first rotating handle is required to be rotated, so that the first rotating handle drives the rotating rod to rotate 45-90 degrees clockwise, the rotating plate can be abutted against the outer part of the second fixing piece, the triangular sloping plate slides through the lever, the back surface of the triangular sloping plate is abutted against the square block, and the position of the first rotating handle can be fixed through the abutting of the square block and the triangular sloping plate and the limitation of the second fixing piece;

step S104: in step S103, when the rotating rod rotates, the rotating rod drives the hinge plate to rotate clockwise, so that the hinge plate pushes the push column to slide outwards until the push column is clamped in the limiting hole, when the push column enters the limiting hole, the push column can collide with the arc-shaped tongue plate to enable the arc-shaped tongue plate to slide inwards, so that the arc-shaped tongue plate can drive the first inclined plate to slide, the first inclined plate collides with the second inclined plate, the second inclined plate can be pushed to rise, the sliding plate can be driven to slide upwards, the sliding plate drives the clamping plate to slide upwards, and the clamping plate can leave the clamping groove; then, the second window frame is pushed, so that the second window frame can rotate by taking the pushing column as the circle center, and the second window frame can be independently opened for ventilation;

Step S105: when the second window frame is required to be closed, the second window frame is only required to be rotated to enable the second window frame to be overlapped with the first window frame, then the second rotating handle is rotated clockwise or anticlockwise, the second rotating handle pulls the first pull rope to the outside, one end of the lever can be lifted by the first pull rope, the lever is in a parallel state, then the first rotating handle is rotated anticlockwise, the first rotating handle is enabled to return to an initial position, and the triangular inclined plate can smoothly slide from the top of the lever due to the fact that the lever is in the parallel state;

step S106: in step S105, when the first rotating handle rotates anticlockwise, the hinge plate can pull the push post back, and when the push post is pulled back, the hinge plate does not collide with the arc-shaped tongue plate, so that the clamp plate can enter the clamping groove again under the action of the second spring and the third spring, the arc-shaped tongue plate enters the limiting hole again, and the position of the second window frame is fixed through the clamping connection of the clamp plate and the clamping groove;

step S107: if the first window frame after folding and unfolding in the step S102 is required to be closed, only the first window frame is required to be pulled to be in a parallel state, then the inserting piece is inserted into the jack, and meanwhile, the second inclined plane is abutted against the arc-shaped surface, so that the triangular block is jacked up, the fifth spring is compressed until the inserting piece is completely inserted, and the inclined structural surface of the triangular block is abutted against the first inclined plane;

Step S108: then the first pull rod and the second pull rod are held by hands, the second pull rod is pulled to move downwards, the second pull rod drives the sleeve rod to slide outwards, the sleeve rod pulls the pull rope through the connecting rod, the pull rope pulls the blocking plate to move downwards, the blocking plate does not collide with the triangular block any more, and meanwhile the blocking plate drives the blocking rod to move downwards and does not collide with the blocking column;

step S109: then the first pull rod is pulled downwards, the first pull rod pulls the triangular block to slide downwards through the pulling column, and the triangular block is abutted against the first inclined plane, so that the inserting piece can drive the second window frame to move towards the direction of the shell continuously, and accordingly all the first window frames can be tensioned;

step S1010: when the first window frame is unlocked, only the second pull rod is needed to be pulled again, so that the blocking plate moves downwards to avoid abutting against the triangular block, and then the first window frame is released, and at the moment, the blocking plate abuts against one surface, namely the back surface, of the triangular block, which is close to the supporting plate, due to the elastic force of the sixth spring;

Then the first pull rod is pushed upwards, the triangular block is pushed to slide upwards by the pulling column, and in the process, as one side of the triangular block, which is close to the blocking plate, is of an inclined surface structure, when the triangular block slides upwards, the blocking block automatically collides with the inclined structural surface of the triangular block by the back surface movement of the triangular block and returns to the initial position, and in the sliding process of the triangular block, the first window frame can be pulled as long as the blocking block is not in collision;

step S1011: finally, the first pull rod is loosened, and the fourth spring pushes the triangular block to reset to the initial position.

The beneficial effects of the invention are as follows:

1. compared with the prior art, the folding opening or closing of the window can be realized by hinging a plurality of groups of first window frames, compared with a single window, the opening space can be increased, and in addition, when the first window frames are closed, the first window frames at the head end can be continuously tensioned through the locking tensioning assembly, so that the subsequent first window frames can be tensioned through the mutual pulling of the first window frames, the manual pushing of the first window frames is not needed, and the window is convenient to use; in addition, through the setting of the switching component, if the first window frame is not required to be opened, the second window frame can be independently opened through the switching setting of the switching component, so that the function of a single window is realized, and the window can be used according to the needs of a user.

2. Compared with the prior art, the switching assembly is used, the hinge plate is driven to rotate by the rotating rod, so that the hinge plate pushes the push column to slide outwards until the push column is clamped into the limiting hole, the push column can collide with the arc-shaped tongue plate when the push column enters the limiting hole, and the sliding plate can be driven to slide upwards by the cooperation of the first inclined plate and the second inclined plate, and the clamping plate is driven to slide upwards by the sliding plate, so that the clamping plate can leave the clamping groove; then at this moment, promote the second window frame can, let the second window frame can be through pushing away the post and rotate as the centre of a circle to can open ventilative with the second window frame alone, realize opening the function alone.

3. Compared with the prior art, in the invention, when the first window frame is closed, only the first window frame is pulled, so that the inserting sheet is inserted into the jack until the inserting sheet is completely inserted, and the inclined structural surface of the triangular block is abutted against the first inclined surface; then pulling second pull rod downward movement earlier so can realize stay cord pulling barrier plate downward movement, no longer contradict the triangle piece, again the first pull rod of downward pulling, first pull rod is through pulling post pulling triangle piece downwardly sliding, the conflict to first inclined plane through the triangle piece, can let the inserted sheet drive the second window frame constantly have the trend towards casing direction motion, thereby can be with the continuous pulling of all first window frames each other, taut, promote barrier plate upward movement through the sixth spring at last, until the barrier plate is contradicted at the afterbody of triangle piece, with its conflict fixed, can lock when taut with first window frame, need not to manually push tightly first window frame one by one, so it is comparatively convenient to use.

4. Compared with the prior art, the safety performance can be improved through the arrangement of the fixing sleeve and the limiting ring, when the push column moves upwards, the arc-shaped tongue plate can only enter the lower part of the limiting ring through the opening, then in the process of rotating the second window frame, the push column can rotate along with the rotation of the second window frame, so that when the push column rotates along with the rotation of the second window frame, other areas of the limiting ring can be abutted against the outer part of the arc-shaped tongue plate, and then the push column can not slide downwards through the abutting of the limiting ring and the arc-shaped tongue plate; the advantage of the arrangement is that the notch corresponds to the arc-shaped tongue plate and the push column can move downwards only when the second window frame rotates to overlap in the first window frame; in the process of rotating and opening the second window frame, the push column cannot move downwards, so that even after the second window frame is opened for a certain angle, the push column cannot retract by rotating the first rotating handle or the second rotating handle, the safety performance is greatly improved, and the second window frame cannot fall off; in addition, the top of fixed cover is the toper structure, and the benefit that sets up like this is, when pushing away the post and withdrawing, and when not leaving spacing hole yet, alright let the arc hyoid sheet advance certain distance to spacing downthehole, and what means is, when pushing away the post and still not fully withdrawing to the mounting groove in, the cardboard just can the joint to the draw-in groove to in advance with the position joint locking of second window frame, further increase security performance.

Then the first pull rod (56) is pushed upwards, the pulling column (75) pushes the triangular block (50) to slide upwards, in the process, as one side of the triangular block (50) close to the blocking plate (70) is of an inclined surface structure, when the triangular block (50) slides upwards, the blocking block (11) automatically collides on the inclined structural surface of the triangular block (50) by the back movement of the triangular block (50) to return to the initial position, and in the sliding process of the triangular block (50), the first window frame (2) can be pulled as long as the blocking block (11) is not collided;

step S1011: finally, the first pull rod (56) is loosened, and the fourth spring (49) pushes the triangular block (50) to reset to the initial position.
