Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figure 1 、 Figure 2 The present utility model provides a new type of suction cup hook, including a hook base 1, a through hole 11 and a hanging hook 12 are provided on the hook base 1, and the through hole 11 is preferably arranged at the center of the hook base 1;

[0028] A suction cup body 2 fixed to the lower surface of the hook base 1, a widened sealing edge 21 is provided on the suction cup body 2, and the widened sealing edge 21 can increase the contact area between the suction cup and the wall surface during use, thereby improving the airtightness. An extension boss 22 is provided at the center of the suction cup body 2, a linking shaft 23 is fixed on the extension boss 22, the extension boss 22 passes through the through hole 11, and a return spring 24 is provided between the suction cup body 2 and the hook base 1;

[0029] A rotating shell 3 rotatably connected to the upper surface of the hook base 1, a linking hole 31 is provided at the center of the rotating shell 3, two guide inclined planes 32 are provided on the inner wall of the linking hole 31, and a relief opening 33 is provided between the guide inclined planes 32. Refer to the figure, there are two relief openings 33 and they are located on the same straight line;

[0030] A positioning cover 4 inserted and fixed on the rotating shell 3, a positioning boss 41 is provided on the positioning cover 4, and the number of the positioning bosses 41 is set corresponding to the number of the relief openings 33;

[0031] During assembly, the linkage shaft 23 extends into the linkage hole 31 through the relief opening 33, and then the rotating shell 3 is slightly rotated until both ends of the linkage shaft 23 move to the lower side of the guiding inclined surface 32. The specific state is as shown in Figure 6 shown. Then, the positioning cover 4 is installed on the rotating shell 3. At this time, the positioning boss 41 extends into the relief opening 33. The specific state is as shown in Figure 5 shown, so as to ensure that the linkage always remains in contact with the guiding inclined surface 32. The overall shape after assembly is as shown in Figure 3 shown.

[0032] During use, the user rotates the rotating shell 3. The linkage shaft 23 gradually moves along the guiding inclined surface 32 towards the higher side of the inclined surface, and pulls the center of the suction cup body 2 to rise through the extension boss 22 to form a vacuum chamber. Referring to Figure 4 it can be seen that at this time, the return spring 24 is compressed, and the suction cup is fixed to the wall surface. During disassembly, the user rotates the rotating shell 3 in the opposite direction, and the linkage shaft 23 descends along the guiding inclined surface 32. At the same time, the return spring 24 also pushes the suction cup body 2 to deform and reset, so as to release the fixed state between the suction cup and the wall surface.

[0033] Referring to Figure 2 , a plurality of connecting buckles 42 and positioning pieces 43 are provided on the positioning cover 4, and a plurality of connecting holes 34 and positioning holes 35 are provided on the rotating shell 3. During assembly, the connecting buckles 42 are inserted into the connecting holes 34 to realize the connection between the two, and the positioning pieces 43 are clamped in the positioning holes 35, then it can be ensured that the positioning boss 41 is exactly in the relief opening 33.

[0034] Referring to Figure 1 , a rotating orientation boss 13 is provided on the hook base 1, and a plurality of orientation notches 36 are provided inside the rotating shell 3. Through the cooperation of the rotating orientation boss 13 and the orientation notches, the direction stability of the rotating shell 3 during rotation is ensured.

[0035] Referring to Figure 2 , the rotating shell 3 of this product is integrally of a hollow structure, so as to save materials. A plurality of reinforcing ribs 37 are provided along the circumferential direction inside the rotating shell 3, and the orientation notches 36 are provided at the lower ends of the reinforcing ribs 37.

[0036] To further improve the sealing performance of the suction cup, a film 25 is provided on the lower surface of the suction cup body 2. The film 25 is closely attached to the widened sealing edge 21. The film 25 can deform synchronously with the suction cup. Through the good ductility of the film 25, the gap between the suction cup and the wall surface can be further reduced. At the same time, a pull tab 26 is provided at one end of the suction cup body 2, and the user can remove the suction cup from the wall surface more labor-savingly through the pull tab 26.

[0037] Referring to Figure 1, a plug hole 221 is provided at the top of the extension boss 22, and the linkage shaft 23 is inserted into the plug hole 221.

[0038] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention.
