Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1-5, an anti-misoperation mechanism for a fire window comprises a fixing piece 1, a hook 2 and a transmission rod 3 which are vertically arranged from top to bottom in sequence, wherein the upper end of the fixing piece 1 is fixedly arranged on the side surface of a window sash, the upper end of the hook 2 is in threaded connection with a transversely arranged screw 4, the left end of the screw 4 is provided with a first guide surface 41, the right side surface of the upper end of the hook 2 is abutted against the left end of a horizontally arranged spring 5, the right end of the spring 5 is abutted against the middle part of the fixing piece 1, the middle part of the hook 2 is rotatably connected with the lower end of the fixing piece 1, the bottom of the hook 2 is abutted against the top of the transmission rod 3, the transmission rod 3 is slidably arranged on the side surface of the window sash;

the user can adjust the height of the first guide surface 41 by rotating the screw 4, so that the first guide surface 41 and the second guide surface 61 cannot be abutted due to errors caused by assembly of the window are avoided;

the anti-misoperation mechanism of the fire window further comprises a piece to be collided 6, the piece to be collided 6 is fixedly arranged on the side face of the window frame, and a second guide face 61 which is opposite to the first guide face 41 is arranged on the piece to be collided 6.

As shown in fig. 1, when the fire window is opened, the bottom of the hook 2 abuts against the top of the transmission rod 3.

As shown in fig. 2, when the fire window is closed, the bottom of the hook 2 does not abut against the top of the transmission rod 3.

As shown in fig. 6, furthermore, the middle of the fixing plate 1 is provided with a groove 11 horizontally arranged, the right end of the spring 5 is abutted to the groove 11, and the groove 11 is used for fixing the right end of the spring 5, so that the spring 5 is not easy to fall off from the fixing plate, and the normal use of the misoperation preventing mechanism of the fire window is ensured.

Furthermore, the middle part of the hook 2 is rotatably connected with the lower end of the fixing sheet 1 through a bolt 7.

The utility model provides a fire prevention window prevents maloperation mechanism's theory of operation is:

when the fire window starts to be automatically closed in case of fire, firstly, the window sash drives the fixing piece 1, the hook 2, the transmission rod 3, the screw 4 and the spring 5 to move towards the piece 6 to be collided, which is fixedly arranged on the window frame; then, the first guide surface 41 on the left end of the screw 4 abuts against the second guide surface 61 on the blade to be struck 6; then, the sheet to be collided 6 pushes the screw 4 to move towards the side face of the window sash, the screw 4 drives the upper end of the hook 2 to move towards the side face of the window sash, and at the moment, under the action of the bolt 7, the lower end of the hook 2 moves towards the side face of the window frame, so that the bottom of the hook 2 is not abutted to the top of the transmission rod 3, and the transmission rod 3 can slide upwards along the side face of the window sash; at the same time, the fire window is locked by a locking mechanism (not shown);

when a fire disaster is over and the fire window needs to be opened, firstly, the handles of the two-point locks are rotated downwards with force, the transmission rod 3 moves upwards under the action of the two-point locks, the transmission rod 3 drives the buckle piece structure in the locking mechanism to slide upwards on the side surface of the window sash, and the buckle piece structure is separated from the lock tongue structure in the locking mechanism fixedly arranged on the window frame, so that the fire window is unlocked; then, the window sash is pushed open, so that the window sash is kept in a normally open state, at the moment, the first guide surface 41 at the left end of the screw 4 is not abutted to the second guide surface 61 of the sheet to be collided 6 any more, the spring 5 drives the upper end of the hook 2 to move towards the side face of the window frame under the action of the elastic force of the spring 5, and the lower end of the hook 2 moves towards the side face of the window sash under the action of the bolt 7; then, the handles of the two-point lock are loosened, the handles of the two-point lock are bounced upwards, the transmission rod 3 moves downwards under the action of the two-point lock, the bottom of the hook 2 is abutted against the top of the transmission rod 3 again, at the moment, the transmission rod 3 cannot slide upwards along the side face of the window sash, the buckle piece structure in the locking mechanism cannot generate displacement under the condition that a user rotates the two-point lock carelessly, the normal use of the locking mechanism is guaranteed, the normal closing of the fire window in the case of fire is also guaranteed, and therefore the life safety of the user is guaranteed.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
