DETAILED DESCRIPTION

[0026] like Figures 1 to 4 The embodiment 1 of the present invention is shown as a fan cover 2 mounting structure, comprising a motor cover 1 and a fan cover 2, the motor cover 1 is used to mount the motor, the motor cover 1 comprises a rear cover 3 and an end cover 4, the end cover 4 covers the top opening of the rear cover 3, the end cover 4 is fixedly connected to the rear cover 3 by bolts, the fan cover 2 comprises a front air cover 5 and a rear air cover 6, a mounting hole 7 is provided in the middle of the rear air cover 6, a buckle block 8 is provided on the inner side of the mounting hole 7, at least two buckle blocks 8 are provided, the buckle blocks 8 are evenly distributed around the central axis of the mounting hole 7, the buckle block 8 is provided with a card slot 9, the card slot 9 is an open slot, the card slot 9 is provided on the side of the buckle block 8, the motor cover 1 and the matching surface of the inner side of the mounting hole 7 are provided with a card block 19, In this embodiment, a first connecting column 14 is provided on the top of the end cover 4, and the first connecting column 14 is provided in the mounting hole 7. The mating surface is the side surface of the first connecting column 14. Therefore, the clamping block 19 is provided on the side of the first connecting column 14. The first connecting column 14 and the mounting hole 7 are clearance-matched, that is, the first connecting column 14 and the mounting hole 7 can rotate relative to each other, and the clamping block 19 can be rotatably embedded in the clamping groove 9. The connection between the rear air hood 6 and the motor hood 1 is realized by the cooperation between the clamping block 19 and the clamping groove 9. When disassembling, it is only necessary to rotate the motor hood 1 and turn the clamping block 19 out of the clamping groove 9 of the buckle block 8 to separate the motor hood 1 from the rear air hood 6. The disassembly and assembly are simple, and there is no need to use bolts, nuts and other connecting parts, and the production efficiency is high.

[0027] A limit block 13 is provided at the bottom of the block 19, and the limit block 13 is arranged at one end of the block 19. The limit block 13 is vertically connected to the block 19 in an "L" shape. When the block 19 is rotated into place, the limit block 13 abuts against the end of the buckle block 8, preventing the block 19 from continuing to rotate, thereby playing a limiting role. A positioning groove 10 is provided on the top of the end cover 4, and the positioning groove 10 is fan-shaped. A protruding positioning block 11 is provided on the inner side of the mounting hole 7. The positioning block 11 is arranged in the positioning groove 10. When the end cover 4 rotates, the positioning block 11 moves in the positioning groove 10. When the block 19 is completely embedded in the slot 9, the positioning block 11 is located at one end of the positioning groove 10. When the positioning block 11 is located at the other end of the positioning groove 10, the block 19 is completely separated from the slot 9. On the one hand, the positioning groove 10 limits the positioning block 11. On the other hand, people can intuitively judge whether the block 19 is installed in place by the position of the positioning block 11 in the positioning groove 10, which is convenient for disassembly and assembly.

[0028] The top surface of the elastic locking block 12 gradually drops in the direction away from the positioning block 11, which plays a guiding role and is convenient for moving the positioning block 11. When the positioning block 11 is installed, it is on the elastic locking block 12 and the elastic locking block 12 is pressed. When the positioning block 11 is rotated to disengage from the elastic locking block 12, the elastic locking block 12 rebounds and realizes locking. When unlocking, the elastic locking block 12 is pressed down, and the end of the elastic locking block 12 will drop. The height of the elastic locking block 12 is lower than the positioning block 11, and the positioning block 11 can move on the top surface of the elastic locking block 12 to realize the unlocking of the positioning block 11. The locking structure is stable and easy to operate.

[0029] The front wind hood 5 and the rear wind hood 6 are detachable connection structures, which can generally be connected by bolts or a snap-on structure. A mounting convex wall 16 is provided at the bottom of the front wind hood 5, and a mounting groove 17 that cooperates with the mounting convex wall 16 is provided at the rear wind hood 6. The mounting convex wall 16 is provided in the mounting groove 17 to facilitate the positioning and installation of the front wind hood 5 and the rear wind hood 6. A groove 18 is provided between the inner side of the mounting groove 17 and the wind net of the rear wind hood 6 to increase the stability of the rear wind hood 6 structure and prevent the shrinkage of the plastic during molding from affecting the shape of the wind net.

[0030] like Figures 5-6 The second embodiment of the present invention shown is different from the first embodiment in that a second connecting column 15 is provided on the top of the rear cover 3, the end cover 4 is provided in the second connecting column 15, the second connecting column 15 is provided in the mounting hole 7, the clamping block 19 is provided on the side of the second connecting column 15, the positioning block 11 is fixedly connected to the end cover 4 by a fixing bolt, and the bolt fixing hole is provided at the end of the positioning block 11 installed in place. In this embodiment, the elastic locking block 12 is replaced by a fixing bolt to realize the locking of the positioning block 11, and the structure is relatively simple.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
