[0009] Furthermore: one end of the waterproof body facing away from the positioning column is provided with a waterproof rib adapted to the chassis guard plate.
[0010] The technical solution of the utility model has the following advantages:
[0011] 1. The utility model provides a waterproof protective cover adapted to a chassis guard plate of an automobile. The waterproof protective cover is arranged between the automobile chassis and the chassis guard plate. During installation, the positioning column is first inserted into the circular hole on the automobile chassis, and then the live wire, armature wire, main power wire, brake wire and other wires are passed through the harness hole for unified storage, and finally the fastening nails are passed through the threaded holes to fix the entire waterproof body and the chassis together, and then the chassis guard plate is connected to the waterproof body. This is superior to the prior art.

[0034] On the basis of the above embodiment: the waterproof body 1 is provided with a waterproof rib 6 adapted to the chassis guard plate at one end thereof which is away from the positioning column 2 .
[0035] The above-mentioned specific improvement is: by setting the waterproof rib 6, the connection tightness between the waterproof protective cover and the chassis guard plate can be increased, thereby improving the waterproof ability between the two.
[0036] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods.
