[0026] Referring to Figure 1 A false mullion, comprising a first frame 100 and a second frame 200, wherein the first frame 100 is provided with a first baffle 110 on one side in the left-right direction, and the rear side of the first frame 100 is provided with a mounting groove 120; the second frame 200 is located behind the first frame 100, and the front side of the second frame 200 is connected with a heat insulation strip 210, the heat insulation strip 210 is inserted into the mounting groove 120, and the heat insulation strip 210 abuts against the right inner side wall of the mounting groove 120.

[0027] As can be seen from the above, when installing the false mullion, the first frame 100 and the second frame 200 are respectively connected to one side of the movable fan 300 in the front-rear direction. Since the first frame 100 and the second frame 200 are of a split structure, they can be directly installed on the front-rear position of one side of the movable fan 300 during installation and connection, and the heat insulation strip 210 is inserted into the mounting groove 120 to shield and close the space between the first frame 100 and the second frame 200, which can improve the overall appearance and form a heat insulation cavity to ensure the heat insulation effect between indoor and outdoor. By setting the first frame 100 and the second frame 200 and the design of the heat insulation strip 210 inserted into the mounting groove 120, the heat insulation strip 210 can be adjusted in the front-rear direction, so that the false mullion can adapt to different fan widths, improving the versatility and installation flexibility of the false mullion, simplifying the production process, reducing the types of required parts for different sizes of fan widths, and facilitating installation and maintenance.

[0028] The mounting groove 120 has a movable gap, and the heat insulation strip 210 is easy to shake in the mounting groove 120 when subjected to external force after being inserted into the mounting groove 120. Therefore, a structure for further fixing the heat insulation strip 210 can be installed in the mounting groove 120. Specifically, the left inner side wall of the mounting groove 120 is provided with a first adhesive strip groove, and a sealing adhesive strip is arranged in the first adhesive strip groove. The sealing adhesive strip presses the heat insulation strip 210 against the right inner side wall of the mounting groove 120. By arranging the first adhesive strip groove on the left inner side wall of the mounting groove 120 and installing the sealing adhesive strip therein, the sealing adhesive strip can press the heat insulation strip 210 more tightly against the right inner side wall of the mounting groove 120, enhancing the sealing and stability between the heat insulation strip 210 and the mounting groove 120. This effectively improves the heat insulation and sound insulation performance of the door and window, prevents dust and rain from entering, and improves the overall performance and durability of the door and window.

[0029] The sealing rubber strip has a certain elastic deformation capacity, so as to press the thermal insulation strip 210 in the mounting groove 120. There is only a certain gap between the sealing rubber strip and the left inner side wall of the mounting groove 120, so that the thermal insulation strip 210 can pass through. Alternatively, the sealing rubber strip directly abuts against the left inner side wall of the mounting groove 120. When the thermal insulation strip 210 is installed, the thermal insulation strip 210 passes through the gap between the sealing rubber strip and the left side wall of the mounting groove 120. The sealing rubber strip is elastically extruded, so that the sealing rubber strip more tightly presses the thermal insulation strip 210 against the left inner side wall of the mounting groove 120. In order to enhance the elastic deformation capacity of the sealing rubber strip, in the embodiment, the sealing rubber strip comprises a connecting portion 131 and a pressing portion 132 connected with each other. The connecting portion 131 is clamped in the first rubber strip groove. The pressing portion 132 is a hollow structure. The middle part of the side of the pressing portion 132 away from the connecting portion 131 is arched away from the connecting portion 131, and the thermal insulation strip 210 is pressed against the right inner side wall of the mounting groove 120. The sealing rubber strip comprises the connecting portion 131 and the pressing portion 132. The connecting portion 131 is used for cooperating with the first rubber strip groove. The pressing portion 132 is a hollow structure, which can provide good elastic deformation. The pressing portion 132 can further press the thermal insulation strip 210 against the right inner side wall of the mounting groove 120. The sealing performance is improved, and the stability of fixing the thermal insulation strip 210 is enhanced. In addition, the hollow pressing portion 132 reduces the weight of the rubber strip, while maintaining the necessary structural strength. The sealing rubber strip can maintain good elasticity and sealing effect after long-term use.
