[0023] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0024] like Figures 1 to 4 As shown, a suction cup structure that facilitates exhaust includes a suction cup shell 1 and a suction cup body 2 connected to the inside of the suction cup shell 1, a top sheet 3 is installed between the suction cup shell 1 and the suction cup body 2, and the top sheet 3 is provided with a plurality of exhaust ribs 31 on a side wall facing the suction cup body 2. In specific implementation, the exhaust ribs 31 are used to press the back of the suction cup body 2 downward along with the suction cup shell 1 during the downward pressing process of the suction cup to achieve exhaust. The suction cup body 2 is a rubber-coated suction cup. Among them, the plurality of exhaust ribs 31 are evenly distributed on the top sheet 3, so as to provide even downward pressure, ensure the uniformity of exhaust, help the suction cup to form a more uniform contact pressure, and thus enhance the adsorption performance of the suction cup.

[0025] As described above, in this case, by installing a top sheet 3 between the suction cup shell 1 and the suction cup body 2, the internal structure of the suction cup is changed, and a greater downward pressure can be provided to the back of the suction cup body 2 during the downward pressure of the suction cup, thereby increasing the suction cup exhaust volume, so as to increase the suction area of ​​the suction cup, make the suction cup's carrying capacity better, and improve the competitiveness of the suction cup product. Specifically, the arrangement of multiple exhaust ribs 31 of the top sheet 3 can directly act on the back of the suction cup body 2 through the exhaust ribs 31 during the downward pressure of the suction cup, forming an effective squeezing effect, forcing the air inside the suction cup and between the suction cup and the adsorbed surface to be quickly discharged, thereby accelerating the exhaust speed, allowing the suction cup to reach a stable adsorption state faster, and improving the adsorption capacity.

[0026] like Figure 1 or Figure 4 As shown, the top sheet 3 extends outward and obliquely downward to form a plurality of elastic pressure arms 32 arranged in a uniform array along the circumferential direction. In a specific implementation, the elastic pressure arms 32 can be elastically expanded when subjected to force and adaptively rebound when not subjected to force, and when the suction cup is in a flattened state, the ends thereof abut against the back of the suction cup body 2. In a specific implementation, the elastic pressure arms 32 are made of elastic material.

[0027] As described above, in this case, through the provision of multiple elastic pressure arms 32, elastic deformation can occur when subjected to external pressure so that the suction cup can adaptively adjust its shape and size to better adapt to the contour of the attachment surface; and when a tight fit is formed between the suction cup body 2 and the external surface to be attached, since the end of the elastic pressure arm is tightly against the back of the suction cup body 2, and the elastic pressure arm 3 itself has a certain resilience, they will work together to maintain this negative pressure state, so that when there are slight pressure changes or vibrations outside, the elastic pressure arm 3 can also absorb these changes through its elastic deformation, thereby maintaining the stability of the negative pressure inside the suction cup, thereby improving the adsorption stability; in addition, the multiple elastic pressure arms 32 can cooperate with the multiple exhaust pressure ribs 31 to press down the back of the suction cup body 2 together during the downward pressing process, thereby significantly improving the exhaust efficiency.

[0028] like Figure 1 or Figure 2 As shown, in a specific implementation, the suction cup housing 1 is provided with a plurality of pressing teeth 33 protruding downward on a side wall body facing the suction cup body 2, and the pressing teeth 33 are arranged at a position relative to the outer periphery of the top sheet 3, so as to avoid the top sheet. In this way, it can be ensured that the pressing teeth 33 can press the back of the suction cup body 2 during the downward pressing process, so as to cooperate with the exhaust pressure rib 31 and the elastic pressure arm 32 to press the suction cup body 2, significantly increase the exhaust volume of the suction cup of this case, and further improve the adsorption force.

[0029] like Figures 1 to 3As shown, in a specific implementation, the suction cup body 2 includes a rubber-coated part 21 and a frame 22 disposed in the rubber-coated part 21; a slot 41 is formed on the inner wall of the suction cup housing 1, and a buckle 42 is protruded upwards from the frame 22 and engaged with the slot 41. The slot 41 has protruding step portions 411 symmetrically disposed in the left and right sides of the slot wall, and strip-shaped protruding portions 412 symmetrically disposed in the front and back sides of the slot wall; the buckle 42 is provided with an elastic buckling portion 421 that can be elastically inserted into the slot 41 and buckled with the protruding step portion 411, and a groove portion 422 that can be inserted into the strip-shaped protruding portion 412.

[0030] As described above, in this case, the matching design of the card slot 41 and the buckle 42 enables the suction cup body 2 to be firmly installed inside the suction cup housing 1, thereby improving the reliability of the connection. The raised step portion 411 and the strip-shaped raised portion 412 in the card slot 41 cooperate with the elastic buckle portion 421 and the groove portion 422 in the buckle 42 to achieve precise positioning and fixation, thereby avoiding the performance of the suction cup being affected by position deviation. Moreover, the four side walls of the card slot 41 are provided with a snap-fit ​​structure, which can further ensure that the suction cup body 2 is more firmly connected to the suction cup housing 1, making the suction cup more stable when subjected to external pressure or impact, thereby extending the service life. In addition, the stable suction cup body connection structure helps to maintain the sealing inside the suction cup, thereby improving the adsorption efficiency.

[0031] like Figure 4 As shown, in a specific implementation, the top sheet 3 is provided with an escape opening 34 for escaping the buckle 42. In this way, on the one hand, it can be installed on the frame 22 through the escape opening 34, and on the other hand, the buckle 42 of the frame 22 can pass through and be engaged with the suction cup housing 1, which is convenient to set, makes the structure more compact, and reduces the overall thickness of the suction cup.

[0032] like Figure 4 As shown, in a specific implementation, a side wall of the top sheet 3 facing the suction cup body 2 is provided with an annular reinforcing rib 5 protruding from the outer periphery of the avoidance opening 34, and a plurality of evenly arranged strip reinforcing ribs 6 extend outward from the outer wall of the annular reinforcing rib 5. In this way, the strength of the outer periphery of the avoidance opening 34 can be enhanced, and the problem of insufficient strength at the opening due to the provision of the opening can be prevented, thereby improving the structural stability of the suction cup of this case.

[0033] like Figure 2 As shown, in a specific implementation, the bottom surface of the exhaust pressure rib 31 is a plane. In this way, a stable contact surface can be provided to press down the back of the suction cup body 2 to enhance the uniformity of the pressure on the back of the suction cup body 2, ensure a stable exhaust effect, and the plane is not easy to damage the suction cup body 2.

[0034] As mentioned above, this case protects a suction cup structure that facilitates exhaust, and all technical solutions that are the same or similar to this case should be shown to fall within the scope of protection of this case.
