[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0017] In the description of the present invention, it should be understood that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", "bottom", "top", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0018] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The rough surface suction cup provided in this embodiment includes: a suction cup 2, an air extraction hole 5 is provided on the suction cup 2, the bottom of the suction cup 2 is an adsorption surface, a small suction cup 8 is provided on the adsorption surface, and a hard fixing part 3 is provided inside the suction cup 2 to increase the rigidity of the suction cup 2.

[0019] One side of the suction cup 2 extends outward to form a deflation angle 4, and the outer circle of the adsorption surface of the suction cup 2 extends downward to form an adsorption circle 7 to increase the adsorption force.

[0020] The suction cup 2 is integrally cast with a soft material such as silica gel, and the hard fixing part 3 is put into the suction cup 2 for molding when the suction cup 2 is cast.

[0021] The hard fixing member 3 is a circular iron ring, which has two inner and outer rings, and the outer ring is closer to the bottom adsorption surface of the suction cup 2 than the inner ring.

[0022] The suction cup 2 and the annular iron ring are provided with corresponding fixing holes 6 , and the suction cup 2 can be fixed on the external device through the fixing holes 6 .

[0023] When the rough surface suction cup 1 of this embodiment is working, the bottom of the suction cup 2 is pressed on the rough surface that needs to be adsorbed, and air is sucked outwards through the air suction hole 5 by an external device. As the air at the bottom of the suction cup 2 is sucked away, the suction cup 2 is squeezed and deformed by the atmospheric pressure. Because there is a circular iron ring inside, the suction cup 2 will deform according to the shape of the circular iron ring. Since the outer ring is closer to the adsorption surface than the inner ring, the outermost adsorption circle 7 will wrap the rough surface, and each small suction cup 8 has a rough surface that is adsorbed, thereby enhancing the adsorption capacity; when the suction cup 2 needs to be removed, the air release corner 4 at the bottom edge of the suction cup 2 is lifted upward, and air enters the bottom of the suction cup 2 along the lifted part. Under the action of atmospheric pressure, the shape of the suction cup 2 is restored, thereby releasing the rough surface. The suction cup 2 can also be removed by using an external device to release air through the air suction hole 5.

[0024] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
