[0004] To solve the above technical problem, the technical scheme of the utility model is as follows: a steel wheel hub center cover, which comprises a body, a logo cover arranged on the front surface of the body, and a fixing mechanism arranged on the back surface of the body, the body is fixed on a steel wheel hub through the fixing mechanism, the fixing mechanism comprises a plurality of clamping legs that are uniformly distributed in the middle of the back surface of the body in a circle, adjacent clamping legs are connected through an arc-shaped plate, a limiting column is arranged between adjacent clamping legs, the root of the limiting column is connected with the arc-shaped plate, a limiting assembly is arranged on the back surface of the body and corresponds to the outer side of the clamping leg, the limiting assembly comprises two top columns, the roots of the top columns are connected with the arc-shaped plate through a connecting plate, a nut cover is arranged on the back surface of the body, and the clamping leg is clamped with the inner side of a center hole of the steel wheel hub. The utility model principle: the connection between the center cover and the wheel hub is realized by clamping the clamping leg with the inner side of the center hole of the steel wheel hub; after the center cover is assembled, the limiting column abuts against the inner side of the center hole, so that the axial pressure borne by the clamping leg is reduced; after the center cover is assembled, the top column abuts against the surface of the steel wheel hub, which helps to improve the clamping force of the clamping leg and enables each clamping leg to maintain a clamped state; the clamping leg, the limiting column, and the top column are all connected with the arc-shaped plate, so that the fixing mechanism becomes a whole, and the structural stability is better.

[0005] As an improvement, the two ends of the arc-shaped half are Z-shaped bent.

[0006] As an improvement, the cross section of the top column is L-shaped, and the top of the top column is provided with a pressing plate.

[0007] As improvement, the front side of the body is provided with several convexes which are uniformly distributed in the circumference, and the back side of the body is formed with grooves for the spokes to extend into, corresponding to the convexes.

[0008] The utility model brings the beneficial effect compared with prior art is:

[0009] The connection between the center cover and the steel wheel hub is realized by the clamping of the clamping legs and the inner side of the center hole; after the assembly of the center cover, the limiting column abuts against the inner side of the center hole, thereby reducing the axial pressure on the clamping legs; after the assembly of the center cover, the top column abuts against the surface of the steel wheel hub, which helps to improve the clamping force of the clamping legs and makes the clamping legs keep the clamping state; the clamping legs, the limiting column and the top column are connected with the arc-shaped plate, so that the fixing mechanism becomes a whole and has better structural stability. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 It is a schematic view of the combination of the center cover and the steel wheel hub.

[0011] Figure 2 It is a schematic view of the back surface of the center cover. DETAILED DESCRIPTION

[0012] The utility model will be further described in combination with the drawings of the specification.

[0013] For example, Figure 1 , 2As shown, a steel wheel hub center cover, the center cover 2 is matched with the steel wheel hub 1, which comprises a body 21, a logo cover arranged on the front surface of the body 21 and a fixing mechanism arranged on the back surface of the body 21, the body 21 is fixed on the steel wheel hub 1 through the fixing mechanism.
