For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0042] Refer to Figures 1 to 5According to the first aspect of the present invention, a suction cup is provided, including a suction cup cover 100, a pressing assembly 200, a suction cup assembly 300 and a limiting structure 400. The suction cup cover 100 has a through channel 110, and the pressing assembly 200 can slide relative to the channel 110. The suction cup assembly 300 is covered by the suction cup cover 100 and is connected to the pressing assembly 200 through the channel 110. The limiting structure 400 includes at least one first limiting portion 410 and at least one second limiting portion 420. The first limiting portion 410 is provided in the channel 110, and the second limiting portion 420 is provided in the pressing assembly 200. The first limiting portion 410 can cooperate with the second limiting portion 420 to limit the deflection of the pressing assembly 200 relative to the suction cup cover 100. The first limiting portion 410 and the second limiting portion 420 can limit the deflection of the pressing component 200 relative to the suction cup cover 100, so that the pressing component 200 can only slide relative to the suction cup cover 100 in the vertical direction of the suction cup adsorption surface. When the suction cup cover 100 is mounted, the pressing component 200 is not deflected by the force, and the force direction is parallel to the adsorption surface of the suction cup, so that the suction cup will not be lifted up, thereby improving the adsorption effect.

[0043] Specifically, the suction cup cover 100 has a groove body for accommodating the suction cup assembly 300, and the groove body has a through channel 110. The pressing assembly 200 passes through the channel 110 and is connected to the suction cup assembly 300. Pressing the pressing assembly 200 can enable the suction cup assembly 300 to slide relative to the suction cup cover 100 and adsorb with the installation base. The first limiting portion 410 is provided on the suction cup cover 100 and is located in the channel 110. The second limiting portion 420 is provided on the pressing assembly 200. The first limiting portion 410 and the second limiting portion are connected. Part 420 can limit the abutment, making it difficult for the suction cup assembly 300 and the suction cup cover 100 to deflect. The specific limiting structure 400 is not limited here. After the pressing assembly 200 and the suction cup assembly 300 pass through the limitation, they can only slide vertically relative to the adsorption surface, and will not deflect from the suction cup cover 100. After the suction cup assembly 300 adsorbs the mounting surface and is mounted, the suction cup assembly 300 is limited by the abutment of the limiting structure 400, making it difficult for it to tilt up, thereby maintaining normal adsorption and improving the adsorption effect.

[0044] Reference Figures 2 to 5 In some embodiments of the present invention, the first limiting portion 410 is configured as a limiting column 411, and the second limiting portion 420 is configured as a limiting groove 421, and the limiting column can slide in cooperation with the limiting groove 421. Specifically, the limiting column 411 matches the shape of the limiting groove 421, and the limiting column 411 can be inserted into the limiting groove 421, so that the limiting column can only slide along the depth direction of the limiting groove 421, that is, the suction cup assembly 300 can only slide along the vertical direction of the suction cup cover 100, so as to achieve the effect of vertical force on the suction cup assembly 300, reduce the occurrence of warping and deflection, and thus improve the adsorption effect.

[0045] ReferenceFigures 6 to 11 It can be understood that the limiting column can be set to be circular, square, triangular or polygonal, and the shape of the limiting groove 421 is set corresponding to the limiting column.

[0046] Reference Figures 2 to 5 In some embodiments of the present invention, the limiting structures 400 are provided in two groups to further enhance the limiting effect. The specific setting positions are not limited here.

[0047] Reference Figures 2 to 5 In some embodiments of the present invention, channel 110 includes a mounting groove 111 and a through hole 112. The through hole 112 is provided on the bottom wall of mounting groove 111. Pressing assembly 200 is mounted in mounting groove 111. Suction cup assembly 300 is connected to pressing assembly 200 through through hole 112. The limiting structures 400 are symmetrically distributed about a line passing through the center point of suction cup cover 100. This can further enhance the limiting effect.

[0048] Specifically, the shape of the mounting groove 111 matches the contour of the pressing assembly 200. The pressing assembly 200 can be installed in the mounting groove 111 and pressed relative to the suction cup cover 100. The suction cup assembly 300 is connected to the pressing assembly 200 through the through hole 112. Operating the pressing assembly 200 can drive the suction cup assembly 300 to adsorb. By arranging the limiting structure 400 symmetrically on the central axis of the suction cup cover 100, the limiting effect can be improved. It should be noted that the two limiting structures 400 can also be arranged in the vertical direction of the suction cup cover 100 to match it with the force direction, which can further improve the limiting effect.

[0049] Reference Figures 2 to 3 In some embodiments of the present invention, at least two protrusions 113 are provided at the bottom of the suction cup cover 100. The protruding ends of the multiple protrusions 113 can be roughly in the same plane, and there is a gap between the protrusions 113 for the suction cup assembly 300 to open. Specifically, the protruding ends of the protrusions can abut against the surface to be installed to support it, thereby propping up the suction cup cover 100, facilitating the pressing of the pressing assembly 200 and the suction of the suction cup assembly 300. The empty area between the at least two protrusions 113 can allow the suction cup assembly 300 to fully open, providing sufficient gaps for the suction cup assembly 300 to fully squeeze out air, thereby improving the suction effect.

[0050] In some embodiments of the present invention, there are three protrusions 113 on the bottom of the suction cup cover 100, and they are evenly distributed along the circumference of the suction cup assembly 300. Specifically, the three protrusions 113 can further enhance the support effect, and the area between the protrusions 113 can still provide the suction cup assembly 300 with sufficient expansion.

[0051] Reference Figures 2 to 5In some embodiments of the present invention, an elastic member 500 is provided between the suction cup cover 100 and the pressing assembly 200. The pressing assembly 200 is provided with a warning portion 210. When the pressing assembly 200 is pressed, the suction cup assembly 300 adheres to the base surface, and the warning portion 210 slides into the channel 110. Specifically, the elastic member 500 can be a spring. The warning portion 210 provided at the pressing assembly 200 can be sunk into the channel 110 as the pressing assembly 200 is pressed downward. The warning portion 210 can be configured as a component with a distinct color. The bottom of the spring can abut against the suction cup cover 100, and the top can abut against the pressing assembly 200. After installation, the spring applies an elastic force toward the pressing assembly 200. When the suction force of the suction cup assembly 300 decreases, the elastic force can drive the pressing assembly 200 upward, at which time the warning portion 210 can be exposed from the channel 110. When the user observes the warning portion 210, they can tell that the suction force of the suction cup has decreased, thus providing a warning effect.

[0052] Reference Figures 2 to 3 In some embodiments of the present invention, the pressing assembly 200 includes a pressing head 220 and a warning portion 210, and the pressing head 220 is snap-connected to the warning portion 210. Specifically, the warning portion 210 can be injection-molded using materials of different colors, and the pressing head 220 and the warning portion 210 can be snap-connected to facilitate assembly of the pressing assembly 200.

[0053] In some embodiments of the present invention, the maximum sliding stroke of the pressing assembly 200 in the channel 110 is H. When the pressing assembly 200 slides out of the channel 110 by a stroke greater than 0.35H, the warning portion 210 is exposed from the suction cup cover 100 . Specifically, during installation, the bottom of the suction cup assembly 300 is against the plane to be installed. When the pressing assembly 200 is pressed down, the suction cup assembly 300 is deformed and squeezes out the air. When the suction cup assembly 300 completes squeezing out the air, the pressing stroke of the pressing assembly 200 is H. At this time, the suction effect of the suction cup assembly 300 is the best. After the suction cup is used for a long time, air will slowly enter, the suction cup assembly 300 will gradually rebound upward, and the pressing assembly 200 will also slide upward. After testing, when the pressing assembly 200 slides upward for 0.35H, the suction force of the suction cup assembly 300 decays to the point where it is about to be difficult to use normally. At this time, the warning part 210 exposes the suction cup cover 100. If the pressing assembly 200 slides further upward, the warning part 210 will be exposed more, so that the user can feel the suction effect, the prompt is more accurate, and it is less likely to have a false prompt.

[0054] Reference Figure 12 and Figure 13 In some embodiments of the present invention, the through hole 112 is configured as a triangle, a square, or a pentagon to limit the rotation of the suction cup assembly 300. This can prevent the suction cup assembly 300 from rotating when subjected to force, thereby further improving the adsorption effect.

[0055] ReferenceFigure 14 In some embodiments of the present invention, the suction cup assembly 300 includes a suction cup member 310, a pressure plate 320, and a snap-fit structure 330. The pressure plate 320 is mounted on the top of the suction cup member 310 via the snap-fit structure 330. Specifically, the pressure plate 320 can cooperate with the suction cup member 310 to enable the suction cup member 310 to better absorb deformation. The pressure plate 320 and the suction cup member 310 can be detachably connected via the snap-fit structure 330, making assembly more convenient.

[0056] Reference Figure 14 In some embodiments of the present invention, a connecting column 311 is provided on the top of the suction cup member 310, and the clamping structure 330 includes an avoidance hole 331 and a clamping portion 332. The avoidance hole 331 is provided on the pressure plate 320, and the clamping portion 332 is provided on the side wall of the connecting column 311. The clamping portion 332 can pass through the avoidance hole 331, and by rotating the connecting column 311, the clamping portion 332 can be clamped with the pressure plate 320. Specifically, the middle part of the pressure plate 320 can be set as an avoidance hole 331. The specific shape of the avoidance hole 331 can be set as a circular hole, and clearance holes are set on both sides of the circular hole. A connecting column 311 extending upward is set on the top of the suction cup part 310, and the side wall of the connecting column 311 can be provided with two protruding clamping parts 332. During installation, the connecting column 311 and the clamping part can pass through the entire avoidance hole 331. After passing through, the suction cup part 310 is rotated, and the clamping part 332 can be rotated to stagger the clearance hole and can be clamped with the pressure plate 320. At this time, the clamping part 332 cannot pass through the avoidance hole 331, so as to realize the assembly of the suction cup part 310 and the pressure plate 320, and the installation is more convenient.
