Description

Fixed knot of rain-proof cover constructs

Technical Field

The utility model relates to a rain-proof cover field of motor, more specifically say, it relates to a fixed knot of rain-proof cover constructs.

Background

The motor of vertical installation, generally all can be at the rain-proof cover of installation on the end shield of tail end for prevent that debris or rainwater from falling into in the end shield and bumping with rotatory outer fan, perhaps the rainwater is through non-axle extension end axle through-hole department entering in the motor, thereby arouse stator insulation system's destruction.

The traditional rain cover is fixed by welding fixing blocks with corresponding quantity on the inner walls of the end cover and the rain cover respectively, threaded holes are formed in the fixing blocks, and then the fixing blocks are connected through a support plate and screws.

However, in the fixing structure, the rain cover is a thin-wall part, and the deformation of the rain cover is easily caused when the fixing block is welded with the rain cover, so that the appearance cannot be ensured, the working hours are more, and the processing cost is higher. Meanwhile, the welding precision is difficult to control, so that the support plate is difficult to install, if the support plate selects a thick steel plate, when the threaded holes cannot be aligned, shaping is difficult, and if the support plate selects a thin steel plate, the support strength is difficult to guarantee.

The current chinese patent with an authorization publication number of CN208623438U discloses a rain cover for a motor, which comprises a conical cover, wherein the conical cover is connected with a ventilation shell through a connecting sheet, and the connecting sheet, the conical cover and the ventilation shell are fixed through rivets.

However, when the motor needs to be overhauled, the rain cover is difficult to detach through rivet fixing, and the installation is inconvenient.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a fixed knot of rain-proof cover constructs, its advantage that has the assembly portably, quick, zero risk.

In order to achieve the above purpose, the utility model provides a following technical scheme:

a fixed structure of a rain cover comprises an end cover, an end cover window, the rain cover and a plurality of supporting columns; one end of the supporting column penetrates through the end cover window and then is in threaded connection with the end cover, the end cover window is fastened with the end cover, and the other end of the supporting column is connected with the rain cover through a fastening screw.

Further, the support column includes straight pole portion, straight pole portion one end be provided with the screw rod portion that the end shield is connected, the other end seted up with fastening screw complex screw hole.

Furthermore, a tool withdrawal groove is formed in one end, close to the straight rod part, of the screw rod part.

Further, two opposite flat grooves are formed in the supporting column.

Furthermore, the fastening screw is sleeved with a gasket in contact with the rainproof cover.

To sum up, the utility model discloses following beneficial effect has:

1. the connection of the rain cover and the end cover is realized by adopting the supporting columns, and meanwhile, the end cover window and the end cover can be fastened tightly, so that the effects of attractive appearance and cost saving are achieved;

2. the two ends of the supporting column are in threaded connection, so that the effects of simple and convenient assembly, quickness and zero risk are achieved;

3. when the motor needs to be overhauled and maintained, the rain cover can be quickly disassembled and assembled, so that the working efficiency can be improved, and the scrapping risk is reduced.
