Detailed Description

The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The present embodiment provides a detachable motor rainproof structure, as shown in fig. 1-2, which includes a fan housing 100 and a ceiling 200, wherein the fan housing 100 is covered outside a fan of a motor, an air inlet is formed on an end surface of the fan housing 100, and the ceiling 200 is disposed corresponding to the air inlet, so as to reduce rainwater and impurities from entering the motor from the air inlet. The wind shield 100 is provided with a first mounting hole, the ceiling 200 is provided with a second mounting hole corresponding to the first mounting hole, a sleeve 300 is arranged between the wind shield 100 and the ceiling 200, two ends of the sleeve 300 are respectively supported on the ceiling 200 and the wind shield 100, the ceiling 200, the sleeve 300 and the wind shield 100 are fixedly connected through a bolt 400, and the bolt 400 penetrates through the first mounting hole, the sleeve 300 and the second mounting hole. The ceiling 200 and the fan housing 100 are detachably connected by the bolts 400 and the sleeves 300, so that the assembly is simple, the installation is convenient, the ceiling 200 with different sizes and shapes can be conveniently replaced in different use environments, and the ceiling 200 can be detached in a cleaner use environment.

The bolt 400 includes a bolt 410 and a nut 420, a nut 411 of the bolt 410 abuts against an inner side of the wind cover 100, the nut 420 abuts against an outer side of the ceiling 200, a washer 422 is disposed between the nut 420 and the ceiling 200, the nut 420 is of a cap type, and the nut 420 covers an end of the bolt 410. The cap nut 420 can play a role in locking, and can effectively prevent other foreign matters in the water cargo from entering the bolt 400, thereby playing a role in rust prevention and prolonging the service life. The outer tip of nut 420 is the sphere form, and nut 420's lid is the sphere promptly, can improve the security in the use, avoids the injury of edges and corners to the human body.

Set up the screw and stepping down the groove 421 in the nut 420, the screw and the coaxial intercommunication in groove 421 of stepping down, the diameter that steps down groove 421 is greater than the diameter of screw. Thus, the stress on the inner wall of the receding groove 421 is avoided, and the damage of the cap of the nut 420 due to the stress can be avoided.

The nut 420 has a protrusion operating portion 423 on an outer wall corresponding to the relief groove 421, and the operating portion 423 has a regular hexagonal shape.

Bolt 400 is a square neck bolt 400 and the first mounting hole is a square hole, and neck 412 of bolt 400 mates with the square hole. Thus, the bolt 400 does not rotate relative to the hood 100, and the nut 420 is easily screwed into the screw 410.

The bore diameter of the sleeve 300 is larger than that of the second mounting hole. This can improve the stability of abutting the sleeve 300 against the wind cowl 100 and the ceiling 200.
