[0030] Next, refer to Figures 1-5Describe the suction cup assembly 100 according to an embodiment of the present utility model. By setting the mutual cooperation among the mounting shell 1, the pressing structure 4, the rotating member 2, and the elastic member 5, the rotating member 2 can be switched between the first limiting slot 11 and the second limiting slot 12 along the circumferential direction to drive the elastic suction cup 3 to perform telescopic movement, thereby realizing the adsorption and non-adsorption of the elastic suction cup 3. The overall process is simple to operate, stable in movement, and the adsorption process is stable, firm, and has a good adsorption effect.

[0031] As Figures 1-5 shown, the suction cup assembly 100 according to an embodiment of the present utility model includes: a mounting shell 1, a rotating member 2, an elastic suction cup 3, and a pressing structure 4.

[0032] The mounting shell 1 is provided with a first limiting slot 11 and a second limiting slot 12 distributed along the circumferential direction. The depth of the first limiting slot 11 in the axial direction of the mounting shell 1 is greater than the depth of the second limiting slot 12 in the axial direction of the mounting shell 1.

[0033] Specifically, both the first limiting slot 11 and the second limiting slot 12 play a limiting role. The mounting shell 1 is configured as a cylindrical structure. The inner side wall of the mounting shell 1 is provided with the first limiting slot 11 and the second limiting slot 12, and the two are distributed along the circumferential direction of the mounting shell 1. In the axial direction of the mounting shell 1, the depths of the first limiting slot 11 and the second limiting slot 12 are different, and the limiting effect can be realized at two different depths respectively.

[0034] Furthermore, the depth of the first limiting slot 11 is greater than the depth of the second limiting slot 12, which can respectively limit the mounting parts connected to the mounting shell 1, enable the mounting parts to be limited and fixed at different positions in the axial direction of the mounting shell 1, and the mounting parts are limited in the circumferential direction of the mounting shell 1, improving the mounting strength and balance of the two.

[0035] The rotating member 2 is movably installed in the mounting shell 1. The rotating member 2 is provided with a clamping portion 21. An elastic member 5 is provided between the rotating member 2 and the mounting shell 1. The elastic member 5 is adapted to push the rotating member 2 to move axially and make the clamping portion 21 be clamped in one of the first limiting slot 11 and the second limiting slot 12.

[0036] Specifically, the rotating member 2 can move relative to the mounting shell 1, and its movement modes include linear motion and rotational motion, etc. The rotating member 2 is located inside the mounting shell 1, and the rotating member 2 is provided with a clamping portion 21. The clamping portion 21 is used for limiting cooperation with one of the first limiting slot 11 and the second limiting slot 12, and an elastic member 5 is provided between the rotating member 2 and the mounting shell 1, that is, the two ends of the elastic member 5 are elastically pressed against the rotating member 2 and the mounting shell 1 respectively. Among them, the elastic member 5 can be configured as a spring. Through the elastic force of the elastic member 5, the rotating member 2 can move relative to the mounting shell 1.

[0037] Furthermore, the activity mode includes a combination of linear motion and rotational motion, wherein the mounting shell 1 is a fixed end, and the elastic member 5 does not move relative to the mounting shell 1. When the spring applies elastic force to the rotating member 2, the rotating member 2 can move axially. At the same time, the clamping portion 21 of the rotating member 2 can be clamped in the first limiting slot 11, and the rotating member 2 is relatively fixed to the mounting shell 1, and the clamping portion 21 of the rotating member 2 can be clamped in the second limiting slot 12, and the rotating member 2 is relatively fixed to the mounting shell 1.

[0038] The elastic suction cup 3 is located at one axial end of the mounting shell 1, and the edge of the elastic suction cup 3 is pressed against the end of the mounting shell 1. Specifically, the elastic suction cup 3 has a certain adsorption capacity, and the elastic suction cup 3 can provide a certain expansion and contraction space, and can be adsorbed on the surface of certain objects by vacuuming, etc., so as to fix or move the object. Among them, the elastic suction cup 3 is connected to one axial end of the mounting shell 1, and the two can be connected by gluing, etc., and the outer edge of the elastic suction cup 3 is pressed against the mounting shell 1, so that the central area of ​​the elastic suction cup 3 can be used for elastic expansion and contraction.

[0039] Among them, the elastic member 5 is suitable for driving the middle part of the elastic suction cup 3 to move axially along the elastic suction cup 3 when pushing the rotating member 2 to move axially. Therefore, by applying a thrust to the rotating member 2 through the elastic member 5, the rotating member 2 can drive the middle area of ​​the elastic suction cup 3 to move axially to achieve elastic expansion and contraction of the elastic suction cup 3, and when the expansion and contraction space of the elastic suction cup 3 increases, the adsorption capacity can be achieved, and when the expansion and contraction space of the elastic suction cup 3 decreases, the suction of the elastic suction cup 3 can be released. The whole process is simple and reliable, and the elastic expansion and contraction movement of the elastic suction cup 3 is stable, which can improve the stability of the movement process.

[0040] The pressing structure 4 is located on the side of the rotating part 2 away from the elastic suction cup 3, that is, the pressing structure 4 and the elastic suction cup 3 are relatively distributed on both sides of the axial direction of the rotating part 2. For example, the pressing structure 4 can be connected to the rotating part 2 along the axial direction, and the pressing structure 4 plays a pressing role, and the pressing structure 4 can provide pressing force on the rotating part 2 to enable the rotating part 2 to achieve linear motion.

[0041] When under pressure, the pressing structure 4 is suitable for pushing the rotating member 2 to move axially and cooperating with the elastic member 5 to switch the clamping portion 21 from one of the first limit slot 11 and the second limit slot 12 to the other. That is to say, by pressing the pressing structure 4 to apply a thrust to the rotating member 2, and pushing the rotating member 2 to move through the elastic member 5, the clamping portion 21 can be switched from the first limit slot 11 to the second limit slot 12, or the clamping portion 21 can be switched from the second limit slot 12 to the first limit slot 11.

[0042] Further, first, the elastic suction cup 3 is attached to the installation surfaces such as the desktop, wall, and mobile phone. When the user manually presses the pressing structure 4 for the first time, the pressing structure 4 pushes the rotating member 2 to move in the direction of the elastic suction cup 3. At this time, the elastic member 5 is in a compressed state. And when the pressing structure 4 pushes the rotating member 2 to move to the maximum position, the engaging portion 21 can be disengaged from the second limiting slot 12. After removing the pressing force, the elastic member 5 pushes the rotating member 2 to move away from the elastic suction cup 3. At the same time, the rotating member 2 moves circumferentially, so that the engaging portion 21 can be engaged with the first limiting slot 11. At the same time, the middle part of the elastic suction cup 3 moves with the rotating member 2, which can increase the telescopic space of the elastic suction cup 3 to form a vacuum, realizing the adsorption ability.

[0043] And when the user presses the pressing structure 4 again, the movement mode is the same as above. And after the pressing structure 4 pushes the rotating member 2 to move until the engaging portion 21 is disengaged from the first limiting slot 11, the pressing force is removed. Through the thrust of the elastic member 5, the rotating member drives the elastic suction cup 3 to move, which can reduce the telescopic space of the elastic suction cup 3 to release the adsorption force of the elastic suction cup 3, so that the elastic suction cup 3 is disengaged from the installation surface. At the same time, when the engaging portion 21 is engaged with the second limiting slot 12, the position of the rotating member 2 can be ensured to be in a stable state for repeated use next time.

[0044] Thus, through the combined setting of the above linear motion and rotational motion, the user only needs to apply a pressing force to the pressing structure 4 to realize the adsorption positioning and detachment of the elastic suction cup 3 from the installation surface. The overall process is simple to operate, the motion is stable, and the adsorption process is stable and firm, with good adsorption effect. And the suction cup assembly 100 can fix an object through the elastic suction cup 3 or can transfer an object, with a wide range of applications.

[0045] In some embodiments, both the first limiting slot 11 and the second limiting slot 12 are multiple, and the multiple first limiting slots 11 and second limiting slots 12 are distributed alternately along the circumferential direction of the installation shell 1, and the axial slot depths of the first limiting slot 11 and the second limiting slot 12 are different. In this way, when the rotating member 2 rotates along the circumferential direction of the installation shell 1, the engaging portion 21 can be switched from one of the first limiting slot 11 and the second limiting slot 12 to the other, so as to realize the limiting and fixing of the engaging portion 21 at different positions in the axial direction of the installation shell 1, thereby changing the telescopic space of the elastic suction cup 3 to realize the switching between the adsorption state and the non-adsorption state of the elastic suction cup 3. And the multiple first limiting slots 11 and second limiting slots 12 are distributed alternately along the circumferential direction of the installation shell 1, which is similar to the setting principle of a ballpoint pen, so that the rotating member 2 can realize the switching between the adsorption state and the non-adsorption state when rotating in the same direction, which can maintain the continuity of the motion and has a good adsorption effect. Among them, the rotating direction of the rotating member 2 can be clockwise or counterclockwise.

[0046] Specifically, such as Figure 3and Figure 5 As shown, the first limiting slot 11 and the second limiting slot 12 are both distributed along the circumferential direction of the mounting shell 1, and the two are staggeredly distributed in the circumferential direction of the mounting shell 1. And in the circumferential direction of the mounting shell 1, the number of the first limiting slots 11 and the second limiting slots 12 needs to be set the same. In this way, staggered distribution can be achieved, and when the clamping part 21 rotates circumferentially relative to the mounting shell 1, it can be switched from one of the first limiting slot 11 and the second limiting slot 12 to the other to maintain the accuracy of the switching and improve the accuracy of repeated movement.

[0047] Thus, through the above settings, the arrangement of the first limiting slot 11 and the second limiting slot 12 can be neat and orderly, and the processing is simple and convenient.

[0048] Among them, the number of the first limiting slots 11 and the second limiting slots 12 can both be eight, ten, etc., and can be selectively set according to the actual size of the mounting shell 1 and the size of the limiting slots.

[0049] In some embodiments, each first limiting slot 11 is provided with a first guiding inclined surface 111, and each second limiting slot 12 is provided with a second guiding inclined surface 121. Specifically, the first limiting slot 11 and the second limiting slot 12 are open towards the direction of the elastic suction cup 3. Each first limiting slot 11 can be provided with a first guiding inclined surface 111, and each second limiting slot 12 can be provided with a second guiding inclined surface 121. As Figure 3 and Figure 5 shown, both the first guiding inclined surface 111 and the second guiding inclined surface 121 are configured to be inclined relative to the axial direction of the mounting shell 1, and the inclination angles of the first guiding inclined surface 111 and the second guiding inclined surface 121 relative to the axial direction can be the same or different. In this embodiment, the inclination angles of the two relative to the axial direction of the mounting shell 1 are the same.

[0050] Furthermore, when the clamping part 21 moves axially to the maximum position in the first limiting slot 11, it is adapted to cooperate with the second guiding inclined surface 121 under the action of the elastic member 5 to enter the second limiting slot 12, and when it moves axially to the maximum position in the second limiting slot 12, it is adapted to cooperate with the first guiding inclined surface 111 under the action of the elastic member 5 to enter the first limiting slot 11.

[0051] Wherein, the maximum position is the position where the clamping portion 21 disengages from the first limiting card slot 11 and the second limiting card slot 12, that is, when the clamping portion 21 moves axially in the first limiting card slot 11 in the direction of disengaging from the first limiting card slot 11, and when the clamping portion 21 is completely disengaged from the first limiting card slot 11, the elastic member 5 can push the clamping portion 21 to move along the second guiding inclined surface 121 in the direction of engaging with the second limiting card slot 12. And after the clamping portion 21 is engaged with the second limiting card slot 12, the switching of the clamping portion 21 from the first limiting card slot 11 to the second limiting card slot 12 can be realized. And, after the clamping portion 21 moves again, with the same movement mode as above, the switching from the second limiting card slot 12 to the first limiting card slot 11 can be realized.

[0052] Thus, by arranging that both the first guiding inclined surface 111 and the second guiding inclined surface 121 guide the movement of the clamping portion 21, the switching of the clamping portion 21 between the first limiting card slot 11 and the second limiting card slot 12 can be realized, and the circumferential movement of the clamping portion 21 can be realized during the switching process. That is, similar to the principle of a ballpoint pen, the circumferential cyclic switching movement can be realized, and the movement process is stable and reliable.

[0053] And, each first limiting card slot 11 is provided with a first guiding surface 112, and each second limiting card slot 12 is provided with a second guiding surface 122. Both the first guiding surface 112 and the second guiding surface 122 extend axially, and can axially guide and cooperate with the clamping portion 21. That is, when the rotating member 2 moves along with the pressing structure 4, the clamping portion 21 guides and cooperates with the first guiding surface 112 or the second guiding surface 122, so that the axial movement of the rotating member 2 is reliable.

[0054] In some embodiments, the clamping portion 21 is formed with a mating inclined surface 211, and the mating inclined surface 211 is used for guiding and cooperating with the first guiding inclined surface 111 and the second guiding inclined surface 121. In this way, through the guiding and cooperation of the mating inclined surface 211 with the first guiding inclined surface 111 and the second guiding inclined surface 121, the contact area between the clamping portion 21 and the first limiting card slot 11 and the second limiting card slot 12 can be increased, the reliability of the guiding cooperation can be ensured, and the smoothness of the movement of the clamping portion 21 can be improved. Furthermore, the deformation stability of the elastic suction cup 3 can be improved to increase the service life of the elastic suction cup 3.

[0055] Among them, as Figure 4 shown, the mating inclined surface 211 is configured to be inclined relative to the axis of the mounting shell 1, and the inclination angles of the mating inclined surface 211 with the first guiding inclined surface 111 and the second guiding inclined surface 121 are the same, so as to ensure the accurate guiding of the two guiding inclined surfaces to the mating inclined surface 211, and the same inclination angle can reduce the design time cost.

[0056] Among them, the pressing structure 4 is provided with a pressing groove 411, and the inner wall of the pressing groove 411 is adapted to press against the mating inclined surface 211 to drive the rotating member 2 to rotate circumferentially. In this way, after the pressing structure 4 pushes the engaging portion 21 to move, and the mating inclined surface 211 and the pressing groove 411 remain in pressing fit, and when the rotating member 2 moves to the maximum position, the mating inclined surface 211 can be switched to be in guiding fit with the first guiding inclined surface 111 or the second guiding inclined surface 121 to realize the circumferential rotation of the rotating member 2.

[0057] Thus, by setting the pressing groove 411 to be in pressing fit with the mating inclined surface 211, and combining the guiding fit of the mating inclined surface 211 with the first guiding inclined surface 111 and the second guiding inclined surface 121, the circumferential rotation of the rotating member 2 can be realized, and further the switching of the engaging portion 21 between the first limiting card slot 11 and the second limiting card slot 12 can be realized, so as to realize the adsorption and non-adsorption of the elastic suction cup 3 to the mounting surface, and the overall structure switching process is reliable and the movement mode is simple.

[0058] In some embodiments, the pressing structure 4 includes a plurality of pressing teeth 41 spaced apart circumferentially, and a pressing groove 411 is formed between two adjacent pressing teeth 41, and the pressing teeth 41 are formed with a pressing inclined surface 412 that presses against the mating inclined surface 211.

[0059] Specifically, as Figure 4 shown, the pressing structure 4 is provided with a plurality of pressing teeth 41, and the plurality of pressing teeth 41 are evenly spaced apart circumferentially along the pressing structure 4. A pressing groove 411 is formed between two adjacent pressing teeth 41, and the pressing groove 411 is open toward the rotating member 2. The pressing teeth 41 are provided with a pressing inclined surface 412, and the pressing inclined surface 412 is configured to be inclined relative to the axial direction, and the inclination direction of the pressing inclined surface 412 is the same as the inclination angle and direction of the mating inclined surface 211. Such a setting can increase the contact area between the engaging portion 21 and the pressing structure 4, ensure reliable pressing between the two, improve the smoothness of the movement of the engaging portion 21, and further improve the deformation stability of the elastic suction cup 3 to improve the service life of the elastic suction cup 3.

[0060] Thus, by setting the pressing inclined surface 412 to press against the mating inclined surface 211, the pressing structure 4 can limit the rotating member 2 axially, and the pressing structure 4 can reliably push the rotating member 2 to move. After the rotating member 2 rotates, the mating inclined surface 211 can be in pressing fit with one of the pressing inclined surfaces 412 of the plurality of circumferential pressing teeth 41 to realize the limiting effect of the pressing structure 4 on the rotating member 2.

[0061] Among them, the number of the pressing teeth 41 can be eight, nine, ten, etc., and can be selectively set according to the actual size of the pressing structure 4 and the size of the pressing groove 411.

[0062] In some embodiments, there are multiple engaging portions 21. The multiple engaging portions 21 are spaced apart circumferentially on the rotating member 2, and the number of the engaging portions 21 is less than or equal to half of the number of the first limiting slots 11.

[0063] Specifically, the multiple engaging portions 21 are evenly spaced apart along the outer circumference of the rotating member 2, so that the multiple engaging portions 21 can be in pressing fit with the corresponding multiple pressing slots 411, enabling the pressing structure 4 and the rotating member 2 to have multiple pressing positions, improving the connection reliability between the two, and having good balance.

[0064] Among them, the number of the engaging portions 21 can be set to half of the number of the first limiting slots 11, and the number of the engaging portions 21 can also be set to be less than half of the number of the first limiting slots 11. That is, when the number of the first limiting slots 11 is ten, the number of the engaging portions 21 can be set to five, four, etc. In this way, the multiple engaging portions 21 can rotate circumferentially with the rotating member 2, respectively realizing the switching between the first limiting slot 11 and the second limiting slot 12, and the multiple engaging portions 21 are simultaneously in limiting cooperation with the first limiting slot 11 or the second limiting slot 12, enabling the rotation of the rotating member 2 to be stable and reliable, so as to improve the stability of the adsorption force of the elastic suction cup 3.

[0065] And as Figure 3 and Figure 4 shown, each engaging portion 21 protrudes from the outer peripheral wall of the rotating member 2 in a direction away from the center of the rotating member 2. Among them, the pressing tooth portion 41 is located between the first limiting slot 11 and the outer peripheral wall of the rotating member 2. The protruding distance of the engaging portion 21 is set to be equal to the distance between the outer peripheral wall of the rotating member 2 and the slot width of the first limiting slot 11, or the protruding distance of the engaging portion 21 is slightly less than the distance between the outer peripheral wall of the rotating member 2 and the slot width of the first limiting slot 11. In this way, the engaging portion 21 can always be in limiting cooperation with the pressing slot 411, and the engaging portion 21 can be in limiting cooperation with the first limiting slot 11 and the second limiting slot 12, thereby ensuring the normal operation of the adsorption function of the elastic suction cup 3.

[0066] In some embodiments, a connecting structure 31 is connected to the middle of the elastic suction cup 3. Among them, the connecting structure 31 includes a first disc portion 311, an intermediate cylindrical portion 312, and a second disc portion 313. The first disc portion 311 axially presses against the middle of the rotating member 2 and is in circumferential transmission cooperation with the rotating member 2. The intermediate cylindrical portion 312 is connected between the first disc portion 311 and the second disc portion 313. The second disc portion 313 is connected to the middle of the elastic suction cup 3.

[0067] Specifically, as Figure 3 and Figure 4As shown, the connection structure 31 is arranged between the rotating member 2 and the elastic suction cup 3, and the connection structure 31 includes a first disc body portion 311, an intermediate column portion 312 and a second disc body portion 313 which are connected in sequence, wherein the first disc body portion 311, the intermediate column portion 312 and the second disc body portion 313 can be constructed as a circular structure, and the first disc body portion 311 is connected to the middle part of the rotating member 2. Specifically, the first disc body portion 311 and the rotating member 2 are pressed together along the axial direction to ensure the connection reliability between the two, and the first disc body portion 311 and the rotating member 2 are circumferentially driven, wherein the rotating member 2 It can move relative to the first disk body 311. In actual design, a snap-in protrusion 3111 can be set in one of the first disk body 311 and the rotating member 2, and a snap-in groove 22 can be set in the other, and the snap-in protrusion 3111 and the snap-in groove 22 both extend in the circumferential direction, and the snap-in protrusion 3111 and the snap-in groove 22 are set correspondingly, and the snap-in protrusion 3111 and the snap-in groove 22 are snap-fitted, so that the first disk body 311 and the rotating member 2 can be connected, and the first disk body 311 can move circumferentially relative to the rotating member 2. It has a simple structure, is easy to process, and has stable movement.

[0068] In this way, the first disk body 311 and the rotating member 2 are provided to be pressed together along the axial direction, so that the contact area between the two can be increased, thereby improving the reliability of the press-fit between the two.

[0069] And if Figure 3 As shown, the middle column portion 312 is supported and connected between the first disk portion 311 and the second disk portion 313, and the second disk portion 313 is connected to the middle portion of the elastic suction cup 3, so that when the rotating member 2 is pressed and moves, the rotating member 2 presses against the first disk portion 311, and the second disk portion 313 drives the elastic suction cup 3 to reduce the cavity space between the mounting surface, and when the elastic member 5 pushes the rotating member 2 to move in the opposite direction, the rotating member 2 drives the second disk portion 313 and the elastic suction cup 3 to increase the cavity space between the mounting surface to achieve adsorption capacity.

[0070] Among them, the second disk body portion 313 and the elastic suction cup 3 can be connected by gluing, or can be connected by snap-fitting or plug-in, and in actual design, the first disk body portion 311, the middle column portion 312 and the second disk body portion 313 can be integrally formed, which is simple and convenient to process, has a stable and reliable structure, and can reduce the number of connection steps between each other.

[0071] In some embodiments, a pressing flange 13 extending radially inward is provided at one axial end of the mounting shell 1, the edge of the elastic suction cup 3 presses against the side of the pressing flange 13 facing away from the rotating part 2, and the elastic part 5 presses between the pressing flange 13 and the first disk body 311.

[0072] Specifically, Figure 3 and Figure 5As shown, in the axial direction of the mounting shell 1, the mounting shell 1 is provided with a pressing flange 13 at one end close to the elastic suction cup 3, the pressing flange 13 extends radially inward, and the pressing flange 13 extends along the circumference of the mounting shell 1, the elastic suction cup 3 is a disc structure, and the edge of the elastic suction cup 3 is pressed and matched with the side of the pressing flange 13 away from the rotating member 2, that is, the elastic suction cup 3 is located at the outermost side, so that the elastic suction cup 3 can be directly in contact with the mounting surface, and the rotating member 2 can drive the elastic suction cup 3 to elastically expand and contract relative to the mounting surface through the connecting structure 31, and the elastic member 5 extends axially, one end of which presses against the first disc body 311, and the other end presses against the pressing flange 13, so that one end of the elastic member 5 can be elastically expanded and contracted relative to the other end with the movement of the rotating member 2, thereby realizing the elastic force of the elastic member 5.

[0073] Furthermore, when the rotating member 2 is pressed against the first disk body 311 and moves toward the elastic suction cup 3, the elastic member 5 is continuously compressed during this process, and when the rotating member 2 is not pressed, the elastic member 5 pushes the first disk body 311 and the rotating member 2 to move away from the elastic suction cup 3, so that the second disk body 313 can drive the middle part of the elastic suction cup 3 to achieve elastic expansion and contraction, thereby realizing adsorption capacity.

[0074] Therefore, by providing the pressing flange 13 and the edge of the elastic suction cup 3 for pressing and fitting, the connection area between the two can be increased, so as to improve the reliability of the connection between the pressing flange 13 and the elastic suction cup 3.

[0075] In some embodiments, a guide block 42 is disposed on the outer peripheral wall of the pressing structure 4 , and the guide block 42 cooperates with the first limiting slot 11 along the axial guiding direction.

[0076] Specifically, Figure 3 and Figure 4 As shown, the guide block 42 is protruding from the outer peripheral wall of the pressing structure 4, and the guide block 42 is constructed as a square structure. The guide block 42 moves axially with the pressing structure 4, as shown in FIG. Figure 3 and Figure 5 As shown, the first limiting slot 11 is provided with a connecting portion 113 on the side away from the elastic suction cup 3, the connecting portion 113 passes through the end of the mounting shell 1 away from the elastic suction cup 3, and the connecting portion 113 extends axially, wherein the circumferential width of the guide block 42 is smaller than the circumferential groove width of the connecting portion 113, which facilitates the guide block 42 to extend into the connecting portion 113 and cooperate with the connecting portion 113 along the vertical guide.

[0077] Further, when an external force is applied to the pressing structure 4, the communication part 113 between the guiding block 42 and the first limiting card slot 11 is in axial guiding cooperation, enabling the pressing structure 4 to press the rotating part 2 to move axially. Moreover, the circumferential width of the clamping part 21 is also smaller than that of the communication part 113. In this way, when the clamping part 21 switches to cooperate with the first limiting card slot 11, the clamping part 21 can move along the first guiding inclined surface 111 to the communication part 113 and continue to move axially away from the elastic suction cup 3, thereby increasing the cavity space between the elastic suction cup 3 and the mounting surface to achieve the adsorption capacity.

[0078] Among them, multiple guiding blocks 42 can be provided, and the number of guiding blocks 42 can be the same as that of the first limiting card slots 11, enabling multiple guiding blocks 42 to be in guiding cooperation with the first limiting card slots 11 simultaneously, ensuring the stable and reliable movement of the pressing structure 4 and guaranteeing the repeated movement accuracy to ensure the adsorption capacity of the elastic suction cup 3.

[0079] In some embodiments, the suction cup assembly 100 further includes a limiting member 6. A limiting convex edge 43 is provided on the outer peripheral wall of the pressing structure 4, and the limiting convex edge 43 extends into the mounting shell 1. The limiting member 6 is detachably connected to the mounting shell 1 and axially limits the limiting convex edge 43 within the mounting shell 1.

[0080] Specifically, as Figure 1 、 Figure 2 and Figure 5 shown, axially on the mounting shell 1, the limiting member 6 is connected to the end of the mounting shell 1 away from the elastic suction cup 3. For example, the limiting member 6 can be detachably connected to the mounting shell 1 through fasteners such as bolts, or the two can be connected by clamping, gluing, etc. At least part of the structure of the limiting member 6 extends radially inwards. A limiting convex edge 43 is provided on the outer periphery of the pressing structure 4, and the limiting convex edge 43 protrudes outside the pressing structure 4. Among them, both the limiting convex edge 43 and the limiting member 6 extend circumferentially, and the limiting member 6 is provided with a limiting surface 61 on the side close to the limiting convex edge 43, and the limiting convex edge 43 is provided with a pressing surface 431 on the side close to the limiting member 6. The pressing surface 431 and the limiting surface 61 are in limiting contact. In this way, during installation, first extend the limiting convex edge 43 of the pressing structure 4 into the mounting shell 1 and connect the limiting member 6 to the mounting shell 1, enabling the limiting member 6 to axially limit the limiting convex edge 43 and install the pressing structure 4 within the mounting shell 1.

[0081] Thus, by setting the limiting cooperation between the limiting member 6 and the limiting convex edge 43, the pressing structure 4 can be installed in the mounting shell 1 to prevent the pressing structure 4 from detaching from the mounting shell 1. Moreover, the limiting member 6 and the limiting convex edge 43 are in limiting contact in a circumferential circle, making the installation of the pressing structure 4 reliable, and its connection method is simple and convenient for disassembly and assembly.
