DETAILED DESCRIPTION

[0032] The utility model will be further explained in detail below in combination with the drawings.

[0033] Embodiment:

[0034] Referring to Figures 1-4 the utility model discloses a lower guard plate of automobile bumper, including the guard plate body 1. The guard plate body 1 is installed at the bottom of the car. The side of the guard plate body 1 close to the car is defined as the top.

[0035] The first through hole 11 is formed in the middle of one side of the guard plate body 1, and the pressing plate 2 is integrally extended from each side of the inner peripheral wall of the first through hole 11 to the center. The surface of the top of the pressing plate 2 is coplanar with the top surface of the guard plate body 1.

[0036] The replacement plate 12 is provided at the first through hole 11, and the connecting plate 21 is formed by extending the four side walls of the replacement plate 12 outward. The shape of the pressing plate 2 is the same as that of the connecting plate 21. The bottom of the replacement plate 12 is fixedly provided with a plurality of reinforcing plates 3.

[0037] Each side of the pressing plate 2 towards the replacement plate 12 is fixedly provided with a plurality of bolts 22. A plurality of second through holes 23 are formed in each connecting plate 21. The shape and position of the bolt 22 correspond to the shape and position of the second through hole 23. The bolt 22 and the replacement plate 12 are connected by a nut.

[0038] The top surface of the replacement plate 12 is coplanar with the top surface of the guard plate body 1. The thickness of the replacement plate 12 is 1.4-1.7 times the thickness of the guard plate body 1. In this embodiment, the thickness of the replacement plate 12 is 1.5 times the thickness of the guard plate body 1.

[0039] The guard plate body 1 and the replacement plate 12 are provided with four connecting assemblies 4.

[0040] Each connecting assembly 4 includes a rotating plate 41 that is rotatably mounted on the replacement plate 12. A curved plate 42 is provided on the side of each rotating plate 41 away from the reinforcing plate 3. A first curved through hole 43 is formed on one side of the curved plate 42, and one end of the first curved through hole 43 passes through the curved plate 42.

[0041] Four positioning blocks 44 are provided on the top of the guard plate body 1 . As the arc plate 42 rotates, the positioning blocks 44 are located in the corresponding first arc-shaped through holes 43 .

[0042] Each curved plate 42 is provided with a sliding block 5 on one side close to the replacement plate 12. The replacement plate 12 has four annular grooves 51 on the top, and the positions of the annular grooves 51 correspond to the positions of the sliding blocks 5. The sliding blocks 5 are located in the corresponding annular grooves 51 and are slidably connected to the corresponding annular grooves 51.

[0043] The replacement plate 12 is provided with four stoppers 6, which are arranged close to the corresponding arc-shaped plates 42. The stoppers 6 limit the corresponding arc-shaped plates 42 from moving in the opposite direction of the opening direction of the corresponding first arc-shaped through holes 43.

[0044] The implementation principle of the above embodiment is:

[0045] When replacing the replacement plate 12 , the old replacement plate 12 is first removed.

[0046] Then, a new replacement plate 12 is placed in a suitable position, at which point the arc-shaped plate 42 is completely located above the replacement plate 12. The bolts 22 are passed through the corresponding first through holes 11.

[0047] Next, the rotating plates 41 are rotated one by one, driving the curved plates 42 to rotate. As the curved plates 42 rotate, they gradually approach the corresponding positioning blocks 44, until the positioning blocks 44 are located within the corresponding first curved through holes 43. At this point, the curved plates 42 are partially located above the guard plate body 1. When the curved plates 42 can no longer rotate in the original direction, the operator stops rotating the rotating plates 41.

[0048] When the four curved plates 42 are rotated, the replacement plate 12 can be initially fixed to the guard plate body 1 without the operator's manual support. The operator uses a tool to put the nut on the corresponding bolt 22, and fixes the replacement plate 12 to the guard plate body 1 through the nut and the pressure plate 2.

[0049] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
