The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-2, a urea pump protective cover structure includes:

the device comprises a urea box, a main protective cover 2 and an auxiliary protective cover 3;

wherein the main protective cover 2 is connected to the lower end of the urea box in a matching way;

the auxiliary shield 3 is rotatably connected to the main shield 2;

a plurality of buckles 4 are arranged at the joint of the main protective cover 2 and the urea box;

the buckle 4 is matched with the urea box;

the auxiliary protective cover 3 is provided with a retaining ring 31;

a boss 21 is arranged on the side part of the main protective cover 2;

the retaining ring 31 corresponds to and fits the boss 21.

Particularly, the urea pump is in urea case lower extreme, the urea pump protection casing is connected and is used for protecting the urea pump in the urea pump lower extreme, the urea pump protection casing includes main protection casing 2, vice protection casing 3, main protection casing 2 is connected through the position that 4 urea casees of buckle correspond, when the assembly, only need correspond buckle 4 with the urea case the position aim at disect insertion can, in addition vice protection casing 3 can be followed main protection casing 1 and opened, the convenient pencil to inside carries out the later stage maintenance to the joint, when normal use, only need close vice protection casing 3 with main protection casing 1, it can to connect through boss 21 and buckle 31, after connecting to the target in place, main protection casing 2, vice protection casing 3 forms complete protection casing.
