In an embodiment of the present invention, the wind shield locking member is a rotary locking member; the rotary locking piece comprises a guide part, and a limiting groove is formed in the guide part. The rotary locking piece comprises a guide part, so that the fan cover is firstly inserted into the shell along the guide part and then rotated in place to ensure that the fan cover is just in the right direction (the boss of the fan cover can be connected with the limiting groove), and the fan cover is reliably connected.
In an embodiment of the present invention, the rotating locking member is circumferentially and uniformly distributed inside the housing. Through circumference evenly distributed, a plurality of rotatory locking pieces lock the fan housing simultaneously for both fixed effects are more firm.
In an embodiment of the present invention, the number of the rotating locking members is 3.
As above, the utility model discloses a connecting piece for new trend system has following beneficial effect: the connecting piece for the fresh air system is suitable for cast-in-place pre-buried one-step forming, avoids a construction mode of opening holes on site, and also avoids a complex procedure of filling joints in the later period of the cast-in-place pre-buried steel sleeve. The indoor fresh air pipeline can be directly connected with the shell (generally, bonding is selected), and the outdoor fan cover can be easily fixed in the shell through the fan cover locking piece. The whole installation process is fast and convenient, the whole stability is high after installation, and the mode that the traditional process needs to be fixed on a wall by screws is avoided. The connecting piece for the fresh air system is also provided with the water baffle with a certain height, so that outdoor rainwater cannot permeate into the room through the connecting piece for the fresh air system. Above-mentioned a connecting piece for new trend system has reduced construction cost, has improved construction quality and efficiency, safe and reliable in the installation.
