Description

Technical Field:

[0001] The utility model relates to the technical field of wheel hub packaging, and more specifically to a protective pad assembly for wheel hub packaging. Background Art:

[0002] When the existing wheel hubs are packaged, foam paper, plastic rings or foam rings are used for protection inside. For example, foam paper is placed on the top surface of the bottom plate of the carton, and then the wheel hub is pressed on the foam paper, and foam paper is covered on the top surface. Then, plastic rings or foam rings are installed on the side walls of the wheel hub for side protection.

[0016] Example, as shown in Figures 1 to 2 A protective pad assembly for wheel hub packaging, including a carton bottom plate 10. The carton bottom plate 10 is a rectangular plate, and EPE protective cushion blocks 20 are fixed on the top surfaces at its four corners;

[0017] Arc-shaped side walls are formed on the opposite wall surfaces of the four EPE protective cushion blocks 20. Inner arc-shaped positioning grooves 21 are formed on the inner side walls of the upper parts of the arc-shaped side walls.

[0018] The central axes of all the arc-shaped side walls coincide. The thickness of the EPE protective cushion block 20 is 10 cm to 15 cm. Its thick thickness greatly improves the supporting effect on the wheel hub.

[0019] The central axes of the inner arc-shaped wall surfaces of all the inner arc-shaped positioning grooves 21 coincide.

[0020] The bottom surface of the EPE protective cushion block 20 can be adhesively fixed to the top surface of the bottom plate 10 of the carton, or it can be:

[0021] At least two positioning concave holes 22 are formed on the middle bottom surface of the EPE protective cushion block 20, vertical insertion holes 11 are formed at corresponding positions on the bottom plate 10 of the carton, an annular groove 12 is formed on the inner side wall at the bottom end of the vertical insertion hole 11, and the vertical insertion hole 11 corresponds to the corresponding positioning concave hole 22; the plastic elastic clamping part 30 is inserted into the vertical insertion hole 11 and clamped on the inner side wall of the corresponding positioning concave hole 22, and a radially extending edge 31 is formed on the outer side wall at the bottom end of the plastic elastic clamping part 30, and the radially extending edge 31 is nested in the corresponding annular groove 12.

[0022] A plurality of outer convex strips (in the shape of a spline) are formed on the outer side wall of the plastic elastic clamping part 30, and the outer convex strips are clamped on the inner side wall of the corresponding positioning concave hole 22. The friction between the plastic elastic clamping part 30 and the inner side wall of the corresponding positioning concave hole 22 is increased through the outer convex strips, the clamping effect is improved, and it is not easy to loosen. And when the outer side wall of the plastic elastic clamping part 30 cannot be firmly clamped on the inner side wall of the corresponding positioning concave hole 22, the EPE protective cushion block 20 needs to be replaced.

[0023] Furthermore, a first positioning concave hole 23 is formed in the middle of the top surface of the EPE protective cushion block 20, a lower clamping part 41 is formed at the bottom end of the side support column 40, an outwardly extending annular convex part 42 is formed on the middle outer side wall of the lower clamping part 41, the outer side wall of the annular convex part 42 is spherical, the lower clamping part 41 is clamped in the corresponding first positioning concave hole 23, and the outer side wall of the annular convex part 42 is pressed against the inner side wall of the first positioning concave hole 23. The annular convex part 42 can elastically expand the inner side wall of the positioning concave hole 23 a little, and through the elastic restoring force of the inner side wall of the first positioning concave hole 23, the clamping and holding effect is improved. The side support column 40 is a plastic column.

[0024] Furthermore, an upper clamping part 43 is formed at the top end of the side support column 40, an upper annular convex part 44 is formed on the middle outer side wall of the upper clamping part 43, the outer side wall of the upper annular convex part 44 is spherical, an EPE protective cushion block 20 with the same structure as the lower EPE protective cushion block 20 and inverted is provided at the top end of the side support column 40, the upper clamping part 43 is clamped in the first positioning concave hole 23 formed in the middle of the bottom surface of the corresponding upper EPE protective cushion block 20, and the outer side wall of the upper annular convex part 44 is pressed against the inner side wall of the corresponding first positioning concave hole 23. The upper annular convex part 44 elastically expands the inner side wall of the corresponding first positioning concave hole 23 a little, and through the elastic restoring force of the inner side wall of the first positioning concave hole 23, the clamping and holding effect is improved.

[0025] Radially extending side portions 45 are formed on the outer side walls of the upper and lower parts of the side support column 40. The bottom surface of the lower side portion 45 is pressed against the top surface of the lower EPE protection cushion block 20, and the top surface of the upper side portion 45 is pressed against the bottom surface of the upper EPE protection cushion block 20.
