Upper dismounting, so set it is convenient ventilating board is cleared up or changed, and ventilating board is in normal use, two montants and its
The positive stop strip of bottom can be supported from the middle part of ventilating board to ventilating board, make the use state of positive stop strip more firm, just
Used in user.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of air scavenger fan overall structure diagram.
In figure：Case body of ventilation fan 1, installing pipe 2, ventilating board 3, cross bar 4, montant 5, the first vertical tube 6, positive stop strip 7, sleeve pipe 8,
Limited block 9, the second vertical tube 10, lid 11, clamp 12, support bar 13.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1, a kind of air scavenger fan, including case body of ventilation fan 1, the bottom of case body of ventilation fan 1 are provided with installing pipe
2, the bottom of installing pipe 2 is connected with horizontally disposed ventilating board 3, and ventilating board 3 is provided in round, and ventilating board 3 and installing pipe 2 it
Between using threaded connection, be connected through a screw thread between installing pipe 2 and ventilating board 3, be easy to when needed dismantle ventilating board 3.It is logical
Annular clamp 12 is connected with the outside of the bottom surface of aerofoil 3, annular clamp 12 can be defined to the position of ventilating board 3, be easy to logical
Aerofoil 3 carries out installing/dismounting, and ventilating board 3 also has certain occlusion effect, by increasing capacitance it is possible to increase the overall appearance of ventilating board 3
Degree.The middle part of ventilating board 3 is provided with the first vertical tube 6, and the bottom surface of ventilating board 3 is provided with the second vertical tube 10, and the second vertical tube 10 is located at
