The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 6, the window opening and closing control device according to the embodiment of the present invention includes a fixing base 1, a moving member 2, a rocker arm 3, a connecting rod 4, a core shaft 5, a limiting frame 6, an elastic element 7, a fastening member 8, and a fusible gasket 9.

The movable piece 2 and the fixed seat 1 can be connected in a reciprocating way; the rocker arm 3 used for connecting door and window leaves or door and window frames is hinged with the fixed seat 1, and a transmission mechanism 10 for driving the rocker arm 3 to swing or driving the movable part 2 to move is arranged between the rocker arm 3 and the movable part 2.

The connecting rod 4 is movably connected with the fixed seat 1, and the connecting rod 4 can move relative to the direction of the hinged end of the rocker arm 3 and pushes the movable piece 2 to move; one end of the mandrel 5 is connected with the connecting rod 4; the limiting frame 6 is fixed on the fixed seat 1, and the limiting frame 6 forms an axial limiting hole 61; elastic element 7 cup joints on dabber 5, and elastic element 7 one end is supported and is leaned on connecting rod 4, and the elastic element 7 other end supports and leans on one side of spacing 6, and elastic element 7's initial condition is in by the compression state.

The fastening piece 8 is connected with the other end of the mandrel 5, the fastening piece 8 is radially provided with a limiting part 81, and the limiting part 81 can penetrate through the limiting hole 61 of the limiting frame 6; the fusible gasket 9 is arranged between the limiting part 81 of the fastener 8 and the other side of the limiting frame 6, and the fusible gasket 9 limits the limiting part 81 of the fastener 8 to penetrate through the limiting hole 61 of the limiting frame 6.

When a fire disaster happens, the fusible gasket 9 is melted, the fastener 8 loses the limitation of the fusible gasket 9, so that the elastic element 7 in a compressed state is restored to the original state, at the moment, the limiting part 81 of the fastener 8 penetrates through the limiting hole 61 of the limiting frame 6 and moves synchronously with the mandrel 5, because one end of the elastic element 7 is abutted against the connecting rod 4, the other end of the elastic element 7 is abutted against one side of the limiting frame 6, the connecting rod 4 is driven to move when the elastic element 7 in the compressed state is restored to the original state, the connecting rod 4 moves to push the movable part 2 to move, the movable part 2 moves to drive the rocker arm 3 to swing under the action of the transmission mechanism 10, and the door and window sash or the door and window frame. Meanwhile, the heat sensitive element is the fusible gasket 9, so that the whole length of the window sash opening and closing control device is shorter, and the stability is improved. Therefore, the utility model provides high casement opening and closing control device's stability subtracts short casement opening and closing control device's whole length, can match the width of multiple casement, and its simple structure.

It should be noted that the fusible gasket 9 may be a fusible metal gasket, the fusible gasket 9 does not deform at a low temperature, the fusible gasket 9 can melt when meeting a preset temperature value, the preset temperature value of the fusible gasket 9 can be customized within a certain range, such as 47-280 ℃, and the fusible gasket 9 is the prior art and is not described herein.

In some examples, the movable member 2 is disposed parallel to the connecting rod 4, and a brake pad 22 is disposed between the movable member 2 and the connecting rod 4. The brake pad 22 can be a nylon brake pad, which can effectively increase the friction between the moving member 2 and the connecting rod 4, and of course, the brake pad 22 can be a brake pad made of other materials. The wind bracing adjusting screw 41 is disposed in the long sliding groove 21 and passes through the brake pad 22, and the wind bracing adjusting screw 41 is adjusted to adjust the gap between the movable member 2 and the connecting rod 4, so as to adjust the friction force between the movable member 2 and the connecting rod 4, so that the window is not easily affected by wind when opened.

In some examples, a brake pad 23 is arranged between the movable member 2 and the head of the wind bracing adjusting screw 41. The brake pad 23 increases the friction between the movable member 2 and the wind bracing adjusting screw 41, so that the window is further less susceptible to wind when opened.

In some examples, the connecting rod 4 is L-shaped, the connecting rod 4 includes a long side 42 and a short side 43, the wind bracing adjusting screw 41 is disposed between the long side 42 of the connecting rod 4 and the moving member 2, and the short side 43 of the connecting rod 4 is connected with the mandrel 5. After the fusible gasket 9 is melted, the elastic element 7 is restored to the original state to drive the connecting rod 4 to move, the connecting rod 4 moves to drive the moving part 2 to move, when the connecting rod 4 moves, the short edge 43 of the connecting rod 4 can abut against the moving part 2, and the short edge 43 of the connecting rod 4 moves to drive the moving part 2 to move.

In some examples, the elastic element 7 is a compression spring, the elasticity of which is good and through which the spindle 5 is easy to pass. In some examples, the fastener 8 is a fastening bolt that facilitates connection with the mandrel 5.
