DETAILED DESCRIPTION

[0021] The utility model will be explained in further detail in combination with the drawings. The drawings are simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the components related to the utility model.

[0022] Please refer to Figures 1-8 A hook assembly, comprising an outer shell 1 and an elastic retractable hook, the bottom of the outer shell 1 is provided with two oppositely arranged buckles one 3, the arrangement of the buckle one can facilitate the overall installation in the car, the top of the outer shell 1 is provided with a flange plate 2, the elastic retractable hook can be retracted in the flange plate 2, the elastic retractable hook comprises a hook 4, under normal circumstances, the outer surface of the hook 4 is flush with the outer surface of the flange plate 2, as shown in Figure 2 , the outer surface of the hook 4 is flush with the outer surface of the flange plate 2 and closed, the hook is hidden, when using, the hook 4 pops out of the flange plate 2 and extends outward, as shown in Figure 1 , at this time, the hook 4 can be hung at the extended hook 4; that is, the hook 4 can be elastically retracted, so that it is retracted or extended from the flange plate 2.

[0023] In the embodiment, the elastic retractable hook further comprises a pressing gear 5, the pressing gear 5 is integrated with the hook 4, the bottom of the pressing gear 5 is provided with meshing teeth 51, the inner wall of the outer shell 1 is provided with a sliding groove 11 and a protruding rib 13, the bottom of the protruding rib 13 is provided with an inclined surface, wherein a gap is left between the bottom of the protruding rib and the inner bottom wall of the outer shell, which is used for the rotation of the rotating gear, the circumference of the pressing gear 5 is provided with a limiting sliding block 52 matched with the sliding groove 11, when pressing the hook 4, the pressing gear 5 moves into the outer shell 1.

[0024] The cam 53 is engaged with the engagement teeth 51 and the engagement teeth 52 are engaged with the engagement teeth 53. The cam 53 is engaged with the engagement teeth 51 and the engagement teeth 52 are engaged with the engagement teeth 53.

[0025] The rebound principle of the hook assembly is similar to that of a spring ballpoint pen. In this embodiment, the outer shell 1 is the fixed part of all parts, acting as a reference and fixing role;

[0026] by Figure 1 For example, when the hook 4 is pressed, the spring 1 62 contracts, the rotating toothed disc 6 moves downward, and the tower spring 55 and the spring 2 54 contract. Since the pressing toothed disc 5 and the rotating toothed disc 6 cooperate with each other through the meshing teeth and the inclined surface, the pressing force will generate a lateral force, causing the rotating toothed disc 6 to move downward, and the groove around the rotating toothed disc 6 cooperates with the protruding rib 13 to prevent the rotating toothed disc 6 from rotating; when the hook 4 is continued to be pressed, the rotating toothed disc 6 moves downward to the bottom and disengages from the protruding rib 13. At this time, the rotating toothed disc 6 is pushed by the (meshing teeth) inclined surface of the pressing toothed disc 5 in the gap to rotate;

[0027] Since the rotating gear disc 6 is subject to the limiting force of the meshing teeth at the bottom of the pressing gear disc 5, the rotating gear disc 6 stops moving after the meshing teeth and the inclined surface are engaged. If you do not let go at this time, it will remain in a relatively stable state.

[0028] When the hook 4 is released from the pressure, the tower spring 55 and the second spring 54 elastically extend, and the tower spring 55 and the second spring 54 will push the whole upward movement. At this time, the oblique teeth of the rotating gear plate 6 will engage with the oblique surface of the bottom of the protruding rib 13. After the rotating gear plate 6 rotates again, it will hang on the oblique surface of the bottom of the protruding rib 13 to prevent the hook 4 from elastically extending; at this time, the hook 4 is in a locked state, and the outer surface of the hook 4 is flush with the outer surface of the flange (such as Figure 2 shown);

[0029] When the hook 4 is pressed again, the tower spring 55 and the spring 2 54 are contracted again, and the rotating toothed disc 6 moves downward and rotates again, so that the rotating toothed disc 6 is separated from the inclined surface at the bottom of the protruding rib 13, and the hook is ejected as a whole (as shown in FIG. Figure 1The hook assembly can be installed in the car, and can also be installed on other objects.

[0030] Based on the above embodiment, the circumference of the outer shell 1 is also provided with a plurality of assembly grooves 12, the bottom surface of the flange plate 2 is provided with a plurality of buckle two 21 matched with the assembly grooves 12, the flange plate 2 is connected with the outer shell 1 through the buckle two 21, and the fixed assembly of the overall structure is realized.

[0031] Based on the above embodiment, the circumference of the outer shell 1 is also provided with a plurality of elastic fins 7, the elastic fins 7 are upwardly inclined, the hook assembly can be installed in the car, and can also be installed on other objects, a hole matched with the assembly is reserved during installation, the whole is installed into the reserved hole, the hook 4 is exposed, the elastic fins 7 are deformed after installation, the assembly degree can be increased through the tension of the elastic fins 7; during use, only the hook 4 needs to be pressed.

[0032] Obviously, the above embodiment is only an example for clearly illustrating, and does not limit the implementation. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the implementation is not required and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
