In this embodiment, the temperature-sensitive positioning device 2 includes a bottom plate 201, a thimble 202, and a heat-sensitive element 206, the bottom plate 201 is welded on the outer wall of the sleeve 101, a top member 203 is hinged to the front end of the bottom plate 201, a vertical plate 204 is disposed at the rear end of the bottom plate 201, a second threaded member 205 is connected to the vertical plate 204 through a thread, the front end of the second threaded member 205 abuts against the top member 203 through the heat-sensitive element 206, and the top member 203 abuts against the rear end of the thimble 202.

The specific operation of temperature sensing positioning is as follows: by twisting the second screw member 205, the front end of the second screw member 205 drives the top member 203 to rotate through the heat sensitive element 206 and press down the thimble 202, so that the tip of the thimble 202 penetrates through the avoiding hole reserved on the circumferential outer wall of the sleeve 101 and then abuts against one of the first positioning holes 105, thereby limiting the rotation of the driving shaft 102.

As shown in fig. 2, in the present embodiment, the torque adjusting assembly 104 includes a connecting shaft 1041, a first ratchet 1042 and a second ratchet 1043 engaged with each other; a multi-edge protrusion 1044 is arranged on the non-gear surface of the first ratchet 1042, the multi-edge protrusion 1044 is embedded into a preset multi-edge hole on the end surface of the connecting shaft 1041, and a multi-edge torsion adjusting groove 1045 is arranged in the center of the gear surface of the first ratchet 1042; a through hole 1046 is formed in the center of the second ratchet wheel 1043, the sectional area of the through hole 1046 is larger than that of the multi-edge torque adjusting groove 1045, so that a multi-edge wrench can be inserted into the multi-edge torque adjusting groove 1045 through the through hole 1046, a plurality of second positioning holes 1047 are formed in the outer circumferential wall of the second ratchet wheel 1043, a third threaded member 1048 is connected to the sleeve 101 through a thread, and one end of the third threaded member 1048 extends into one of the second positioning holes 1047 to limit the second ratchet wheel 1043 to rotate. The multi-edge protrusion 1044 and the multi-edge torque force adjusting groove 1045 are hexagonal.

The utility model discloses an installation use as follows:

(1) the installation process comprises the following steps: the sash connecting plate 504 is fixed to the sash by screws, and the frame connecting plate 505 is fixed to the frame by screws.

(2) The operation process is as follows: firstly, by turning the second screw 205, the front end of the second screw 205 drives the top 203 to rotate through the heat sensitive element 206 and press down the thimble 202, so that the tip of the thimble 202 penetrates through the avoiding hole reserved on the outer circumferential wall of the sleeve 101 and then abuts against one of the first positioning holes 105, and the driving shaft 102 is fixed.

Then, after the polygonal wrench is inserted into the multi-edge torque adjustment slot 1045 through the through hole 1046, the first ratchet 1042 is rotated to rotate the connection shaft 1041 and the driving shaft 102 relatively, so that the torsion force of the torsion spring 103 is accumulated. It should be noted that, since the third screw 408 limits the rotation of the second ratchet 403, the first ratchet 402 can only rotate in one direction, and the torsion of the torsion spring 103 is opposite to the rotation direction of the first ratchet 402, so as to limit the unloading force of the torsion spring 103.

When a fire occurs, the heat sensitive element 206 melts or explodes at a high temperature to fragment and lose the restriction effect on the top piece 203, so that the top piece 203 loses the pressing effect on the thimble 202, and the thimble 202 is separated from the corresponding first positioning hole 105. The drive shaft 102 is rotated by the torsion spring 103.

In this embodiment, the second link 502 is a branch of the multi-link hinge assembly 5 described above. The second link 502 is provided with a coupling structure 4 at its hinged end, the coupling structure 4 being coupled to the drive end of the drive means 1. Specifically, the driving end of the driving shaft 102 penetrates the sash connection plate 504 and the second link 502 in sequence and is connected to the connection structure 4.

When the driving shaft 102 is rotated by the window closing driving force, the driving lever 4031 pushes the second hinge plate 502 to rotate by pressing the sidewall of the arc slot 5021 to complete the window closing action, i.e., the multi-link hinge assembly 5 completes the collapsing action.

It will be appreciated by those skilled in the art that the multi-link hinge assembly 5 described in this patent is not limited to the three-link hinge illustrated in the above embodiments, but may be a two-link, four-link, five-link, six-link, or seven-link hinge.
