Meanwhile, the boss 13 can be completely embedded into the window sash groove body during installation, and stable connection with the window sash is realized.

In this embodiment, an upright fixing plate 22 is provided at one end of the fixing arm 2, and a plurality of through holes (e.g. 2 in this embodiment) for fixedly connecting with the side of the window frame may be provided on the fixing plate 22 to enhance the stability of the connection with the window frame. The other end of the fixed arm 2 is provided with a second groove 21, the upper end surface and the corresponding lower end surface of the second groove 21 are respectively provided with a bottom bracket 5 and a bottom plate 6 (as shown in fig. 6) with the width larger than that of the second groove, the bottom bracket 5 and the bottom plate 6 are connected through an adjustable fastener 7 penetrating through the second groove 21, so that the second groove 21 is clamped between the bottom bracket 5 and the bottom plate 6, and the friction force between the bottom bracket 5 and the fixed arm 2 is adjusted through adjusting the adjustable fastener 7.

Meanwhile, one end of the first connecting plate 3 is hinged to one end of the rotating arm 1 close to the positioning plate 12, the other end of the first connecting plate 3 is hinged to the bottom bracket 5, the fixing arm 2 and the bottom plate 6 through a fastening piece 31, and the first connecting plate 3 is connected with the fixing arm 2 in a sliding mode through the sliding of the bottom bracket 5 and the bottom plate 6 in the second groove 21. And the end of the second connecting plate 4 which is not connected with the rotating arm 1 is hinged with the end of the fixed arm 2 which is close to the fixed plate 22.

Preferably, the bottom support 5 can be in a capsule shape and can be made of copper blocks, so that the bottom support has excellent fire-resistant and wear-resistant properties. Meanwhile, as shown in fig. 2, the bottom sheet 6 may be rectangular, and the adjustable fastener 7 may be a countersunk screw, so that the upper surface of the bottom sheet is flush with the upper surface of the bottom bracket without protrusion, which affects the sealing effect of the window sash.

In this embodiment, the middle portion of the first connecting plate 3 and the second connecting plate 4 are hinged to each other to enhance the structural stability between the two connecting plates. In addition, the length of the rotating arm 1 can be set to be between 17 and 18cm, the length of the fixed arm 2 can be set to be between 15 and 16cm, and the length of the first connecting plate 3 can be set to be between 8 and 9 cm; meanwhile, the second connecting plate 4 is set to be 4mm thick and x25mm wide, and the length of the second connecting plate is set to be 16-17 cm. Therefore, the hinge can provide better supporting force, the stability of the window sash on the rotating arm is improved, and the rotating arm is convenient to open and close.

As shown in fig. 6, one end (the left end shown in the figure) of the fixing arm 2 close to the fixing plate 22 and the other end thereof are both provided with a plurality of counter bores or plane holes for being fixedly connected with the window frame, the screw suspension fastening can be avoided by the setting, the aluminum material on the window frame is tightly attached to the fixing arm in the installation process, so that the stress bearing of the aluminum material is high, the sealing performance is good, and the connection stability between the fixing arm and the window frame is strengthened.

Preferably, the connecting member 10 may be an L-shaped connecting member, and the short arm thereof is connected to the end of the first connecting rod 83 penetrating out of the housing 8 (as shown in fig. 3), and the long arm thereof is connected to the through hole 42 (as shown in fig. 5) provided at the end of the sliding stud 41 provided on the second connecting plate 4, so as to combine the temperature control power device and the hinge into the temperature control window closer. And, in order to ensure that the complete closing of the window sash can be achieved, the return stroke of the elastic mechanism 85 should be greater than or equal to the length of the first groove 11 on the rotating arm 1, so that after the elastic mechanism 85 is completely returned, the sliding stud 41 can be pulled back to the end of the first groove 11, i.e. at the right end of the first groove 11 as shown in fig. 5.

The operation mechanism of the temperature control window closer based on the combination of the temperature control power device and the adjustable invisible hinge embodiment is as follows: when the window sash is opened, the adjustable invisible hinge is in an opened state as shown in fig. 5, and the sliding stud 41 on the second connecting plate 4 slides to the left end of the first groove 11 on the rotating arm 1; when fire breaks out in an indoor unmanned state, the temperature sensing element-temperature control tube 93 in the temperature control power device is broken at high temperature, so that the supporting force clamped between the main body seat 91 and the rotating arm 92 disappears, the rotating arm 92 can rotate freely, the pressing mechanism at the outer end of the second connecting rod 84 is released, the second connecting rod 84 can immediately punch out the second end 82 of the shell 8 under the action of the reset elastic force of the elastic mechanism 85 sleeved outside the first connecting rod 83, the pressing sheet 94 is jacked up to be separated from the top surface of the pressed second connecting rod 84, and the rotating arm 92 automatically rotates towards the main body arm 91 (downwards as shown in fig. 3); the compressed elastic mechanism 85 continues to complete the resetting, the elastic mechanism pushes the end of the first connecting rod 83 to move towards the second end 82 of the housing, the first connecting rod 83 drives the connecting piece 10 clamped at the other end of the first connecting rod 83 at the same time, the connecting piece 10 further pulls the second connecting plate 4 of the adjustable invisible hinge to slide towards the right end of the first groove 11 on the rotating arm 1 (see fig. 5), and the automatic closing of the window sash is finally realized through the connecting rod mechanism of the hinge.
