Description

Technical Field

[0001] The utility model belongs to the technical field of fan installation, and in particular relates to a mounting platform for a crossflow fan. Background Art

[0002] A crossflow fan is also called a crossflow fan. The impeller is a multi-blade, long cylindrical shape with forward multi-wing blades. When the impeller rotates, the airflow enters the blade grid from the opening of the impeller, passes through the inside of the impeller, and is discharged into the volute from the other side of the blade grid to form a working airflow.

[0003] At present, a crossflow fan needs to be fixed on a mounting platform with preset holes using multiple screws before being used in a specified position. Since the screw fixing method requires the alignment of the mounting holes on the fan housing with the preset holes on the mounting platform before the screw locking work can be performed, the crossflow fan has a large transverse structure and high weight, which makes it difficult to move and accurately position it on the mounting platform. In addition, the multiple screw fixing method also has the disadvantage of cumbersome disassembly and assembly process. Utility Model Content

[0009] As a preferred implementation, both the first slider and the second slider are slidably connected in a pitch-adjusting slide groove of the pitch-adjusting slide, and the first slider and the second slider are symmetrically arranged on the pitch-adjusting slide.

[0010] As a preferred embodiment, a clamping opening whose size can be adjusted is provided between the two positioning clamping plates, and a fixed-distance slideway adapted to the crossflow fan housing is provided between the two positioning baffles.

[0011] As a preferred embodiment, a rotation groove is formed through one side surface of the positioning baffle, and rotating shafts are fixed to both ends of the guide roller, and the rotating shafts are rotatably connected to the rotation groove of the positioning baffle.
