Description of the embodiments
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, the present utility model provides the following technical solutions: the utility model provides an automobile bumper, including bumper main part 1, set up at the first connecting rod 2 of bumper main part 1 left side, set up the inside first recess 3 of first connecting rod 2, set up the spring 4 in the inside of first recess 3, set up the second connecting rod 5 in spring 4 left side, set up the backup pad 6 in second connecting rod 5 left side, the inside of second connecting rod 5 is provided with second recess 7, the inside of second recess 7 is provided with gag lever post 8, the inside of bumper main part 1 is provided with first hole 9, the right side intercommunication of first hole 9 has third recess 10, the inside of third recess 10 is provided with limiting plate 11.
The appearance structure shape of the second groove 7 is spiral, the width of the second groove 7 is consistent with the width of the limiting rod 8, and the connecting mode of the limiting rod 8 and the first connecting rod 2 is fixedly connected, so that the limiting rod 8 moves in the second groove 7.
The width of the first hole 9 is consistent with the width of the first connecting rod 2, and the appearance structure of the first connecting rod 2 is cylindrical, so that the first connecting rod 2 rotates in the first hole 9.
The limiting plate 11 is fixedly connected with the first connecting rod 2, and the limiting plate 11 is cylindrical in appearance structure, so that the limiting plate 11 rotates in the third groove 10.
