DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 4 The utility model provides a technical solution: an anti-loosening door handle structure, including a door handle body 2, a cover plate 4, a buckling anti-slip ring 6 and an arc-shaped anti-loosening block 15. The door handle body 2 is located on the left side of the door panel shell 1, and a connecting shaft 3 is installed on the right end of the door handle body 2. The right end of the connecting shaft 3 passes through the door panel shell 1 through a rotating bearing member. The cover plate 4 is fixed to the right end of the outside of the connecting shaft 3, and the cover plate 4 and the right side of the door panel shell 1 are installed and fixed by multiple bolts 5. The left end of the buckling anti-slip ring 6 is provided with multiple bolt head limiting grooves 7 and an annular groove 9. Multiple circular through grooves 8 are opened between the annular groove 9 and the multiple bolt head limiting grooves 7. The buckling anti-slip ring 6 Buckled on the right end of the cover plate 4, multiple positioning cylinders 11 are installed at equal angles on the inner side of the annular groove 9, and positioning rods 12 are inserted into the relative outer ends of the multiple positioning cylinders 11. Micro springs 10 are sleeved on the outside of the multiple positioning cylinders 11 and the multiple positioning rods 12, and spring mounting pieces 13 are installed on the movable ends of the multiple micro springs 10, and anti-slip plug shafts 14 are installed on the other ends of the multiple spring mounting pieces 13, and arc-shaped anti-loosening blocks 15 are installed on the other ends of the multiple anti-loosening plug shafts 14. This design solves the problem that the original device uses multiple anti-loosening limit blocks to limit the head of each fastening bolt, the limiting effect is general, and the installation time is relatively wasted during batch installation.

[0020] As a first embodiment of the present invention, the heads of the multiple bolts 5 are respectively retained within the multiple bolt head retaining grooves 7. The multiple bolt head retaining grooves 7 facilitate the retention of the heads of the multiple bolts 5. The opposite outer ends of the multiple positioning rods 12 are respectively connected to the multiple spring mounting plates 13. The addition of the multiple positioning rods 12 allows the microsprings 10 to slide within the multiple positioning cylinders 11 as they compress or rebound.

[0021] The plurality of anti-loosening plug-in shafts 14 are respectively inserted into the plurality of circular through-grooves 8. By adding the plurality of anti-loosening plug-in shafts 14 and inserting them into the plurality of circular through-grooves 8, it is convenient to install the plurality of arc-shaped anti-loosening blocks 15. The annular side surfaces of the plurality of arc-shaped anti-loosening blocks 15 are all provided with anti-slip grooves. The arc-shaped anti-loosening blocks 15 are respectively against one side of the head of the plurality of bolts 5. By adding the plurality of arc-shaped anti-loosening blocks 15, the arc-shaped anti-loosening blocks 15 are respectively against one side of the head of the plurality of bolts 5, thereby preventing the plurality of bolts 5 from being loosened or coming loose due to external collisions.

[0022] As the second embodiment of the present utility model: in actual use, the buckled anti-slip ring 6 is buckled on the right end of the cover plate 4, so that the heads of multiple bolts 5 are respectively clamped in multiple bolt head limiting grooves 7, so that the buckled anti-slip ring 6 can shield and protect the heads of multiple bolts 5, and at the same time, the elastic force of multiple micro springs 10 can be used to push multiple anti-slip shafts 14 and multiple arc-shaped anti-loosening blocks 15. At this time, the arc-shaped surfaces of the multiple arc-shaped anti-loosening blocks 15 are respectively against one side of the heads of multiple bolts 5, thereby preventing the multiple bolts 5 from loosening or coming loose due to external collision.
