During operation, motor body 1 shakes the irregular miniature bearing 44 that strikes about the in-process pivot 11, and the dynamics of assaulting is steadilyd decrease in proper order under the elastic deformation effect of buffer board 42 and bottom plate 43, consequently through miniature bearing 44 arrange order and specification and dimension, can be fine with the impact force dispersion buffering gradually reduce until recovering normal condition, improve buffering effect.
The working principle is as follows:
by adding the fixing mechanism 2, the bent fixing piece 23 can be freely stretched from the movable cavity 221 of the fixing base 22 according to the position of the mounting hole of the air conditioner base during work, the fixing piece 23 and the locking block 213 are meshed with the lower teeth 231 through the upper teeth 214 in the stretching process so as to force the second fixing piece 25 to move under the driving of the connecting piece 212, the fixing piece 23 with the specified length is stretched according to the distance between the mounting holes on the base and is fixed, the mounting hole on the fixing piece 23 corresponds to the mounting hole, then the bolt 26 is inserted into the mounting hole to preliminarily fix the motor body 1, at the moment, a user twists and rotates the inner hexagonal sleeve at the tail end of the screw rod 24 through an external tool, so that the first fixing piece 21 reversely moves and is abutted to be fixed through the engagement of the upper teeth 214 and the lower teeth 231, thereby the length of the fixing piece 23 is limited, the fixing of the fixing piece 23 is completed, the fixing of the motor body 1 is realized, and compared with the, the maintenance and installation efficiency of maintenance personnel is greatly improved by the mode, and meanwhile, the fixing sheet 23 made of the high-toughness metal material can cooperate with the protection mechanism 3 and the buffer mechanism 4 to play a good role in buffering and damping after the motor body 1 is installed, so that the motor body has better extension and protection in the use process compared with the traditional screw hard fixing mode; by adding the protection mechanism 3 in the device, the protection mechanism 3 in a silent state wraps the surface of the rotating shaft 11 of the motor body 1, the protection mechanism can play a certain role in protecting the rotating shaft 11 on the motor body 1 which is accidentally dropped in the maintenance and installation process, the probability of collision and damage of the rotating shaft 11 and the ground is reduced, and the protection metal sheet 31 is matched with the fixing ring 32, so that the protection of the rotating shaft 11 can be realized when the rotating shaft 11 of the motor body 1 is butted and inserted into an installation hole site in the installation process of the motor body 1, the frequent collision with a foreign object caused by the fact that the rotating shaft 11 of the motor body 1 is plugged in the installation hole site in a dark and narrow working environment is avoided, therefore, the protection metal sheet 31 is preliminarily plugged into the hole site through the fixing ring 32 in use and then extrudes the motor body 1, the protection metal sheet 31 generates elastic deformation and is bent to abut against the surface of the foreign object, the, the distance between the fixing ring 32 and the motor body 1 is gradually reduced, at the moment, the rotating shaft 11 is inserted into the fixing ring 32 through the guide plate 431 in a hole position inserted into an external object, the protective metal sheets 31 are compressed and elastically deformed, the gap between the two connected protective metal sheets 31 is enlarged, the brush 311 elastically resets to shield the gap, shielding protection is realized in the subsequent use process, dust entering is reduced, the probability of dust adhesion on the surface of the rotating shaft 11 is reduced, the structure of the device is protected from multiple aspects before and after the motor body 1 is installed, and the service life of the motor body 1 is prolonged; through adding buffer gear 4 in the device, motor body 1 leads to the wind direction through the drive aviation baffle in the use, this process is because the length of aviation baffle is longer, certain vibration range appears easily in the great consequently motor body 1 use of torsional forces, lead to motor overload damage, consequently combine through utilizing buffer gear 4 and protection machanism 3 and 2 three of fixed establishment, the buffering optimization to the shake furthest that probably produces in its operation, in order to guarantee the normal good operation of motor body 1, improve motor operation life.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
