One end of a sliding support fixing arm props against a side profile of the fixing frame, a tree stand piece is formed at one end, located on the side profile, of the fixing arm, a left pressing block is arranged at the left end of the sliding support fixing arm, a right pressing block is arranged at the right end of the sliding support fixing arm, one end of each of the two pressing blocks spans over and presses the end portion of the fixing arm, a clamping tongue which is inserted into a first slot is formed at the bottom of the left pressing block, the clamping tongue clamps the left end face of the sliding support fixing arm, a slotted hole is formed in the bottom of the right pressing block, and the tree.
The vertical cutting board is pressed at the position corresponding to the vertical cutting, external slots are formed on the two outer sides of the vertical cutting board, the slot edges of the vertical slots on the side surface of the sash frame vertical section bar are inserted into the external slots of the vertical cutting board, internal slots are formed on the pressing end surface of the vertical cutting board pressing the sash frame vertical section bar, and the vertical cutting board is inserted into the internal slots of the vertical cutting board.
After adopting this technical scheme, compare with prior art, this technical scheme has following advantage: through increasing the cooperation that compresses tightly in three primary position department, compress tightly the spout fixed arm on fixed frame, further stabilize the activity fan on the sliding support connecting rod to avoid the activity fan to break away from and fall, improve flat-open window's factor of safety.
Description of the drawings:
FIG. 1 is a structural diagram of the falling off and falling off preventing device for the casement window;
FIG. 2 is an assembly structure diagram of a sliding support and a pressing block in the anti-falling device for the casement window;
fig. 3 is a decomposition structure diagram of the sliding support and the pressing block in the anti-drop falling device for the outer casement window.
The specific implementation mode is as follows:
the present technique is further explained below.
The device capable of preventing falling for the external casement window comprises a fixed frame 1, a movable fan 2 and a sliding support 3, wherein the sliding support 3 is connected with the fixed frame 1 and the movable fan 2, the sliding support 3 is composed of a fixed arm 31, a rocker arm 32 and a connecting rod 33, the fixed arm 31 of the sliding support 3 is inserted into a first slot 11 of the fixed frame 1, the connecting rod 33 is inserted into a second slot (not marked in the figure) at the bottom of the movable fan 2, the rocker arm 32 is connected between the fixed arm 31 and the connecting rod 33, pressing blocks are arranged at two ends of the fixed arm 31, one end of the fixed arm 31 of the sliding support props against a side profile 4 of the fixed frame 1, a standing sheet 5 is formed at one end of the fixed arm 31, which is positioned at the side profile 4, a left pressing block 6 is arranged at the left end of the fixed arm 31 of the sliding support, a right pressing block 7 is arranged at the right end of the sliding support, one end of the two pressing blocks, the left end face of the sliding support fixing arm 31 is clamped by the clamping tongue 8, a groove hole 9 is formed at the bottom of the right pressing block 7, and the standing piece 5 of the fixing arm 31 is inserted into the groove hole 9. A vertical cutting 12 is arranged on the connecting rod 33 corresponding to the leaf frame tree section 10 on one side of the fixed frame 1 when the movable leaf 2 is opened, a tree pressing block 13 is pressed on the position corresponding to the vertical cutting 12, outer slots 14 are formed on two outer sides of the tree pressing block 13, a tree slot edge 15 on the side surface of the leaf frame tree section 10 is inserted into the outer slot 14 of the tree pressing block 13, an inner slot 16 is formed on the pressing end surface of the tree pressing block 13 pressing the leaf frame tree section 10, and the vertical cutting 12 is inserted into the inner slot 16 of the tree pressing block 13.
