[0046] Furthermore, the curtain wall expansion joint connection device also includes a plurality of L-shaped guide members 17, the L-shaped guide member 17 having a fixed section 171 and a guide section 172, the fixed section 171 is correspondingly connected to the first extension frame 111 or the second extension frame 121, and the guide section 172 is located on the inner side of the telescopic sealing strip 16 in the inner and outer directions of the curtain wall, thereby limiting the compression deformation direction of the telescopic sealing strip 16 and preventing the telescopic sealing strip 16 from being stuck between the first box body 151 and the second box body 152 and causing damage to the telescopic sealing strip 16.

[0047] Optionally, the telescopic sealing strip 16 can be configured as an accordion rubber strip to have good thermal insulation and deformation compression properties and a lower cost.

[0048] In addition, in some embodiments, the first extension frame 111 and the second extension frame 121 may be filled with thermal insulation cotton 155, thereby improving the thermal insulation performance of the curtain wall expansion joint connection device.
