[0020] Combination Figures 1-4 A car bumper with an easily detachable grille structure includes a bumper body 1 and a grille 2, as well as a plug-in structure 5 and a nail head 6 disposed on one side of the bumper body 1 for mounting the grille 2. The surface of the bumper body 1 is provided with an installation groove 3, which is fixedly connected to the plug-in structure 5. Guide blocks 4 are provided on both sides of the grille 2, and the surface of the guide blocks 4 is provided with round holes. The plug-in structure 5 includes a fixed shell 51 disposed on one side of the installation groove 3 and a guide opening 52 opened on the surface of the fixed shell 51. The round holes correspond to the guide opening 52. The plug-in structure 5 includes an inner sleeve 53 slidably connected inside the guide opening 52. Steel balls 55 are slidably connected to the surface of the inner sleeve 53. The steel balls 55 are evenly distributed in three groups, and the distance between the three groups of steel balls 55 is less than the diameter of the nail head 6. An anti-accidental collision structure 7 is slidably connected to the outside of the fixed shell 51.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example 1:

[0023] Please see Figures 1-4The plug-in structure 5 includes an inner sleeve 53 slidably connected inside the guide port 52. Steel balls 55 are slidably connected to the surface of the inner sleeve 53. The steel balls 55 are evenly distributed in three groups, and the distance between the three groups of steel balls 55 is less than the diameter of the nail head 6. The surface of the fixing shell 51 is provided with a slot 59. A push plate 58 is slidably connected inside the slot 59. The push plate 58 is connected to the inner sleeve 53. The inner sleeve 53 is frustum-shaped. The surface of the inner sleeve 53 is provided with a groove 54. The groove 54 is evenly distributed in three groups. The steel balls 55 are rollably connected to the groove 54. A spring 57 is provided inside the fixing shell 51. The spring 57 is connected to the inner sleeve 53. An outer shell 56 is provided inside the fixing shell 51. The nail head 6 is frustum-shaped. It is easy to operate and does not require external tools for disassembly and assembly, which is highly efficient.

[0024] The outer side of the fixed shell 51 is slidably connected with an anti-accidental contact structure 7. The surface of the fixed shell 51 is provided with a sliding groove 71. Two sets of sliding grooves 71 are symmetrically provided. The two sets of sliding grooves 71 are slidably connected with sliders 72. A movable shell 75 is provided on one side of the slider 72. One end of the slider 72 is open. A second magnet block 74 is provided on the inner wall of the sliding groove 71. A first magnet block 73 is provided on one end of the slider 72. The first magnet block 73 and the second magnet block 74 are magnetically connected, which effectively prevents accidental loosening caused by accidental contact with the push plate during daily use.

[0025] Specifically, guide blocks 4 are provided on both sides of the grille 2, and guide openings 52 are provided on the surface of the fixing shell 51. A round hole is provided on the surface of the guide block 4 corresponding to the guide opening 52. The guide block 4 is then inserted into the mounting groove 3 on the surface of the bumper body 1, with the round hole on the surface of the guide block 4 corresponding to the guide opening 52. The fixing shell 51 is fixedly connected to the mounting groove 3. Then, the nail head 6 is inserted into the round hole and guide opening 52, thus the nail head 6 contacts the three sets of steel balls 55. As the nail head 6 extends, it causes the three sets of steel balls 55 to be fixed within the groove 54. The three sets of steel balls 55 contact the inner side of the inner sleeve 53, thus widening the distance between the three sets of steel balls 55 and making them tightly adhere to the surface of the nail head 6. The nail head 6 is thus held in place by the three sets of steel balls 55. When the nail head 6 is subjected to external force, because the inner sleeve 53 and the outer shell 56 are frustum-shaped, and the three sets of steel balls 55 roll in opposite directions, the nail head 6 is held more tightly and will not easily fall off. It is only necessary to insert the nail head 6... Installation can be completed inside the fixed shell 51. Pushing the movable shell 75 upward causes the slider 72 on one side to slide upward. The slider 72 causes the first magnet 73 to magnetically attract and fix the second magnet 74 in the groove 71. Then the movable shell 75 covers the push plate 58 to prevent the push plate 58 from being accidentally touched and affecting the fixation of the grille 2 and the bumper body 1, thus realizing the quick installation of the grille 2 and the bumper body 1. When it is necessary to disassemble the grille 2 and the bumper body 1, slide the movable shell 75 downward. The movable shell 75 causes the slider 72 on one side to move away from the push plate 58. The first magnet 73 and the second magnet 74 separate. By pushing the push plate 58 to slide in the groove 59, the push plate 58 causes the inner sleeve 53 to move away from the outer shell 56, thereby increasing the distance between the three sets of steel balls 55, making it easier to pull out the nail head 6, and completing the disassembly of the grille 2 and the bumper body 1. The operation is convenient and does not require external tools for disassembly and assembly, making it highly efficient.
