The side wall of the pulling end is provided with a pulling friction structure 225, and the pulling friction structure 225 is used for increasing friction between the fingers of an operator and the second limiting seat 220, so that the occurrence probability of the situations of a sliding hand and the like is reduced.

The specific use method of the scheme is as follows:

after the window is opened, the door and window is in a micro ventilation mode:

after the window sash 002 is completely closed, the rotating handle 003 is rotated by 90 degrees, the window sash 002 is unlocked from the window frame 001, and then an operator opens the window sash 002, and at this time, the window sash 002 is in the micro ventilation mode. The micro ventilation mode can play a role in ventilating the room; in rainy weather, the rainwater entering the room can be reduced to a certain extent. Meanwhile, under the micro ventilation state, the safety accident caused by climbing the window by children can be avoided.

For a common window, when a child opens the window, the window sash 002 can be opened horizontally, the opening angle of the window sash reaches 90 degrees or more, and if the child climbs the window, a very large safety accident can be caused.

It is necessary that the first mode of windowing is a micro ventilation mode.

Structural state in micro ventilation mode: the riveting fixed cramp 114 on the micro ventilation pull rod 110 slides and sets up the spacing groove that slides at spacing subassembly, and spacing groove that slides limits the position of cramp 114 to play to restrict the position of micro ventilation pull rod 110, and then restrict the opening angle of casement 002. Under the micro ventilation mode, the structural strength of the door and window gap ventilation component is guaranteed, and the safety of the micro ventilation mode can be ensured.

In the conventional micro ventilation mode, the second limiting seat 220 is close to the first limiting seat 210 without being separated, and the fastening nail 114 slides in the limiting sliding groove. The positioning glass bead 221 is clamped on the positioning groove structure 213 to position the second limiting seat 220.

When a child is at home and the child likes to climb the window, the conventional micro ventilation mode does not play a safety role, and the child may move the second limiting seat 220, so that the buckle 114 is separated from the limiting sliding groove, the fan is opened by flat-open, and the child may climb the window to cause a safety accident.

A set of micro ventilation locking function is designed aiming at the condition that the child accidentally drives the second limiting seat 220, and a child lock function is added for the door and window gap ventilation component.

In the conventional micro ventilation mode, the tool is put into the linear groove of the locking rotation shaft 223 to rotate to a locking state, the clamping stop block is buckled on the locking boss 215 to lock the second limiting seat 220, so that the second limiting seat 220 is tightly close to the first limiting seat 210 and is not separated from the first limiting seat, the buckling nails 114 are not separated from the groove all the time, the buckling nails 114 do not influence the opening and closing of the window sashes 002, because the length of the limiting sliding groove of the second limiting seat 220 and the first limiting seat 210 can provide enough space for sliding of the buckling nails 114, the window sashes 002 are all in the micro ventilation mode all the time, namely, the child is locked in the micro ventilation mode, and therefore, the child is very safe and does not need to worry about climbing the window.

When the position limitation of the second limiting seat 220 and the first limiting seat 210 needs to be released, only a tool is needed to be put into the linear groove of the locking rotating shaft 223 to rotate to the unlocking state, the clamping stop block 224 rotates to the side of the clamping stop boss 215, and the clamping stop block 224 is not limited by the clamping stop boss 215, that is to say, the second limiting seat 220 is unlocked, and the second limiting seat 220 can move.

Micro ventilation wind pressure resistant mode:

in windy weather, the window sash 002 in the conventional micro ventilation mode or the child lock micro ventilation mode is blown by wind pressure, so that the window sash 002 is repeatedly closed and opened, noise is produced, the window sash 002 is damaged, and safety accidents are possibly caused by glass breakage. In order to solve the problem, a micro ventilation wind pressure resistant function, namely micro ventilation position locking, is designed.

Structural state at micro ventilation wind pressure resistant mode: the rotation handle 003 in the conventional micro ventilation mode is 90 °, and the wind pressure resistant surface 131 of the wind pressure resistant seat 130 is in a disengaged state from the wind pressure resistant member 113, and the wind pressure resistant member 113 is disengaged from the locking releasing groove 133 and the locking groove 132. In the conventional micro ventilation mode, the rotating handle 003 is rotated to 0 ° (i.e. the rotating handle 003 is rotated from 90 ° to 0 °), in the rotating process of the rotating handle 003, the transmission rod 120 is driven to move upwards, the transmission rod 120 drives the micro ventilation hinged end 112 of the micro ventilation pull rod 110 to move upwards, the wind pressure resistant piece 113 is abutted with the wind pressure resistant surface 131, the wind pressure resistant piece 113 and the wind pressure resistant surface 131 cooperate to position the micro ventilation pull rod 110, the cramp 114 is located in the limit sliding groove, the position of the micro ventilation hinged end 112 is controlled to be positioned by the rotating handle 003, and the micro ventilation hinged end 112, the cramp 114 and the wind pressure resistant piece 113 form three-point fixing, namely the micro ventilation pull rod 110 is fixed, and at the moment, the micro ventilation wind pressure resistant structure state is formed. The window sashes 002 in the micro ventilation wind pressure resistant state are not affected by wind pressure, can not be opened and closed repeatedly, can not produce noise and the like, and a good micro ventilation environment is created.

When the micro ventilation wind pressure resistant mode needs to be released, the rotary handle 003 is rotated from 0 degrees to 90 degrees, so that the wind pressure resistant surface 131 is separated from the wind pressure resistant piece 113, and the conventional micro ventilation mode is returned.

Micro ventilation switching flat-open mode:

in the conventional micro ventilation mode, when the switch is required to be completely opened, the second limiting seat 220 is driven to move downwards, the stop pin arranged at the lower end of the first limiting seat 210 is used for blocking the second limiting seat 220, so that the second limiting seat 220 is prevented from falling off, the positioning glass bead 221 is clamped on the positioning groove structure 213, so that the second limiting seat 220 is positioned by the positioning glass bead 221 and the positioning groove structure 213, and the second limiting seat 220 is separated from the first limiting seat 210 to form a notch. At this time, the window sash 002 is pulled back, the clip 114 slides in the limit sliding groove until the clip 114 slides to the flat-open release notch 240, and the micro ventilation pull rod 110 is reset under the action of the reset piece 140, that is, the micro ventilation mode is released, and then the flat-open door can be completely opened.

Closing the process state, preparing for micro ventilation to be started:

the window sash 002 is completely flat-open, at this time, the rotating handle 003 is 90 degrees, and when flat-open, the second limiting seat 220 is separated from the first limiting seat 210, so as to form a notch; the window sash 002 is closed, and the closed pintle 114 is positioned at the flat-open escape notch 240 between the second spacing seat 220 and the first spacing seat 210. Then the rotating handle 003 is rotated by 0 DEG, the window sash 002 is completely locked, the transmission rod 120 moves upwards in the rotating process of the rotating handle 003, the cramp 114 is driven to enter the limiting sliding groove, and the reset-assisting structure 121 on the transmission rod 120 is arranged on one side of the second limiting seat 220 away from the first limiting seat 210, so that the reset-assisting structure 121 on the transmission rod 120 drives the second limiting seat 220 to move upwards in the upward moving process of the transmission rod 120, and finally the second limiting seat 220 and the first limiting seat 210 are tightly close to each other without separation, thereby enabling the first function of windowing to be micro ventilation and avoiding safety accidents caused by window climbing of children.
