The bayonet holes a are composed of two opposing and L-shaped clamping plates 12. The clamping plates 12 are respectively formed in the middle of the heat dissipation convex plates 11; the clamping plates 12 are provided with an annular locking sleeve 4;

[0021] The locking sleeve 4 includes a cylinder sleeve 41 and annular baffles 42 on both sides of the cylinder sleeve 41, and the baffles 42 respectively rest on the end faces of the front and rear ends of the clamping plate 12; the middle part of the cylinder sleeve 41 is formed with a plurality of rectangular card grooves 43 opposite to the bayonet a, and one side of the card groove 43 is formed with an inlet 44 that passes through the baffle 42 at the rear end of the cylinder sleeve 41, and a plurality of arc-shaped slots 45 adjacent to the inlet 44 are formed on the baffle 42 at the rear end of the cylinder sleeve 41; the baffle 42 at the front end of the cylinder sleeve 41 is fixedly connected to a plurality of internal threaded sleeves 5, and the internal threaded sleeves 5 are screwed with positioning screws 6, and the ends of the positioning screws 6 pass through the baffle 42 and are inserted into the bayonet a of the cylinder shell 1.

[0022] See Figure 4 As shown, several motor mounting brackets 7 are provided around the fan motor, and the motor mounting bracket 7 includes a T-shaped bracket plate 72. The inner end of the bracket plate 72 passes through the card slot 43 of the locking sleeve 4 to form an arc-shaped connecting plate 71, and then the connecting plate 71 and the inner end of the bracket plate 72 form a T-shaped structure. The connecting plate 71 is inserted into the bayonet a between the card plates 12, and the radial movement of the motor mounting bracket 7 is limited by the bayonet a.

[0023] The distance between the front and rear end surfaces of the bracket plate 72 is equal to the distance between the front and rear side walls of the card slot 43 on the locking sleeve 4, the slot width of the card slot 43 on the locking sleeve 4 is greater than the thickness of the bracket plate 72, and the thickness of the bracket plate 72 is equal to the slot width of the inlet 44 on the locking sleeve 4; the arc curvature of the slot 45 is greater than the arc curvature of the connecting plate 71; the locking sleeve 4 is used to limit the axial movement of the motor mounting bracket 7.

[0024] The rear end of the connecting plate 71 extends out of the bayonet a and is inserted into the slot 45 of the locking sleeve 4. The slot 45 is both the entrance for the connecting plate 71 to enter the bayonet a and can constrain the connecting plate 71, further limiting the radial movement of the motor mounting bracket 7, thereby ensuring the stable operation of the fan motor installed in the air guide tube. The bracket plate 72 rests on the side wall of the slot 43 away from the inlet 44.

[0025] There are three groups of bayonet holes a on the outer side of the cylindrical shell 1, and the bayonet holes a are evenly distributed in a ring shape around the central axis of the cylindrical shell 1;

[0026] The number of the locking slots 43 on the locking sleeve 4 is equal to the number of the bayonet openings a, and the locking slots 43 , the entrance 44 and the slot 45 are evenly distributed in a ring shape around the central axis of the locking sleeve 4 .

[0028] The heat dissipation convex plates 11 are evenly distributed in a ring shape around the central axis of the cylindrical shell 1 .

[0029] Working principle: This technical solution is a structure that is convenient for installation and connection on the fan motor. The structure is located on the motor housing. The heat dissipation convex plate 11 is formed with a corresponding clamping plate 12, thereby forming a clamping port a connected to the motor mounting bracket 7. The specific installation process is as follows:

[0030] First, rotate the positioning screw 6 to disengage the positioning screw 6 from the bayonet a, then rotate the locking sleeve 4 to make the inlet 44 face the bayonet a, and the motor mounting bracket 7 can enter the bayonet a through the slot 45 and the inlet 44. Then rotate the locking sleeve 4 to dislocate the motor mounting bracket 7 from the inlet 44, and then use the locking sleeve 4 to lock the motor mounting bracket 7.

[0031] Finally, the positioning screw 6 is screwed into the bayonet a to limit the rotation of the locking sleeve 4.
