[0045] See also Figure 1 , Figure 2 and Figure 4 The first embodiment of the utility model provides a rotary suction cup hook, comprising a top cover 1, a knob 2, a hook body 3, a support 4 and a sealing suction cup 5, one end of the support 4 is connected to the middle area of ​​the sealing suction cup 5, and the other end is connected to the top cover 1 after passing through the hook body 3 and the knob 2, and the support 4 can rotate relative to the hook body 3 and the knob 2; a first slope 11 is arranged on the side of the top cover 1 close to the knob 2, and a second slope 21 is arranged on the knob 2 accordingly, when the knob 2 rotates, it rotates relative to the top cover 1 and abuts against the first slope 11 through the second slope 21 and moves relative to the top cover 1, so as to control the top cover 1 to move axially along the support 4, so as to drive the sealing suction cup 5 to move. The rotary suction cup hook provided by the utility model absorbs and fixes the sealing suction cup 5 on the adsorption surface by adjusting the knob 2, drives the top cover 1 to move in the axial direction of the support 4 through the cooperation of the first slope 11 and the second slope 21, and drives the sealing suction cup 5 to move through the support 4, so as to realize the control of the sealing suction cup 5, has a simple structure, is easy to operate, and makes the rotary suction cup hook stable and safe.

[0046] It should be noted that when the knob 2 is rotated, the knob 2 drives the top cover 1 through the cooperation of the first slope 11 and the second slope 21, and the top cover 1 then drives the middle area of ​​the sealing suction cup 5 to move in the direction away from the external adsorption surface through the support member 4, thereby forming a closed space between the sealing suction cup 5 and the adsorption surface, and a negative pressure is formed inside the space, which produces an air pressure difference with the outside world. As the movement of the sealing suction cup 5 increases, the closed space will also increase, and the air pressure difference with the outside world will also increase. The sealing suction cup 5 is pressed onto the external mounting surface through the air pressure difference, thereby achieving a firm adsorption of the sealing suction cup 5 on the external adsorption surface.

[0047] It should be noted that the utility model first forms a closed space between the sealing suction cup 5 and the external adsorption surface by contacting the sealing suction cup 5 with the external adsorption surface, and then moves the middle area of ​​the sealing suction cup 5 in the direction away from the external adsorption surface in the closed space state to increase the closed space. At the same time, the air pressure inside the closed space is reduced, that is, the pressure is lower than the external atmospheric pressure, thereby forming a negative pressure state between the sealing suction cup 5 and the adsorption surface. The negative pressure state will generate an inward pulling force, that is, the adsorption force, which tightly "sucks" the sealing suction cup 5 on the plane.

[0048] Furthermore, in the process of the first slope 11 and the second slope 21 being in contact and abutting against each other to generate thrust, the lateral force applied to the knob 2 is converted into a longitudinal force that pushes the top cover 1 to move, so that the user can adjust the adsorption force of the rotary suction cup hook by turning the knob 2, which has a simple structure and is easy to operate.

[0049] Preferably, the surfaces of the first slope 11 and the second slope 21 are set to be smooth surfaces to avoid affecting the coordinated rotation of the two.

[0050] Furthermore, the bottom of the second slope 21 is hollow to reduce the weight of the knob 2, so that the rotary suction cup hook has a lighter dead weight to increase the hanging weight.

[0051] See also Figure 2 , Figure 5 and Figure 6 At least two first slopes 11 are centrally symmetrically arranged on the top cover 1, and at least two second slopes 21 are correspondingly centrally symmetrically arranged on the knob 2, so that when the knob 2 rotates, the relative first slopes 11 and second slopes 21 can work better in coordination, thereby improving the stability of the cooperation between the top cover 1 and the knob 2.

[0052] Furthermore, a buckle portion 23 is provided on the end portion on the side with a larger height difference on the second slope 21, and a corresponding matching portion 13 is provided on the end portion on the side with a larger height difference on the first slope 11. When the knob 2 is rotated until the first slope 11 is in contact with the second slope 21, the buckle portion 23 and the matching portion 13 are correspondingly engaged, so that the first slope 11 and the second slope 21 can cooperate better, and avoid pushing the top cover 1 open through the second slope 21 when the knob 2 is rotated, affecting the operation of the rotary suction cup hook.

[0053] Furthermore, after the buckle portion 23 is engaged with the matching portion 13, a clear hand-feel feedback or a "click" sound is generated to the user, indicating that the top cover 1 moves to the maximum position of the enclosed space, that is, a state of being stably adsorbed to the outside world.

[0054] Optionally, the positions of the buckle portion 23 and the matching portion 13 may be alternately arranged.

[0055] In this embodiment, the buckle portion 23 is located on the second slope 21 and protrudes from the top of the second slope 21. Therefore, a corresponding slide rail is opened on the first slope 11. In the process of the first slope 11 and the second slope 21 gradually fitting together, the slide rail is used to accommodate the buckle portion 23, and to improve the stability of the rotation of the knob 2 body by limiting the movement trajectory of the buckle portion 23, to avoid shaking or deviation of the knob 2 and the top cover 1 during movement, and to improve the user's control accuracy over the rotation of the knob 2.

[0056] Furthermore, a receiving cavity 25 is provided on one side of the knob 2 close to the top cover 1 , and the top cover 1 is located in the receiving cavity 25 . The receiving cavity 25 provides a certain movable space for the top cover 1 so that the top cover 1 can move along the moving direction of the support member 4 .

[0057] Specifically, the hook body 3 includes a fixing portion 31, a first mounting groove 12 is opened at the center of the top cover 1, a first through hole 22 and a second through hole 311 are opened at the center of the knob 2 and the fixing portion 31, a second mounting groove 51 is opened at the center of the sealing suction cup 5, the support member 4 passes through the knob 2 and the hook body 3 through the first through hole 22 and the second through hole 311, and the two ends of the support member 4 are fixedly connected to the first mounting groove 12 and the second mounting groove 51, respectively.

[0058] See also Figure 2 and Fig. 9 A mounting portion 315 is provided on the outer periphery of the second through hole 311. The mounting portion 315 is located in the first through hole 22. The mounting portion 315 and the first through hole 22 are corresponding circles. The knob 2 is fixed by the mounting portion 315 and the hook body 3, and rotates relative to the mounting portion 315 when rotating, so that the knob 2 and the hook body 3 are directly installed and matched, which is more stable and avoids the knob 2 from being offset relative to the hook body 3 when rotating, thereby affecting the stability of the overall structure.

[0059] Furthermore, the surface of the first mounting groove 12 close to the hook body 3 corresponds to the mounting portion 315, and when the knob 2 rotates relative to the top cover 1 and the hook body 3, the top cover 1 and the hook body 3 can remain stable by abutting against each other, thereby preventing the rotation of the knob 2 from causing the top cover 1 and the hook body 3 to shift.

[0060] See also Figure 2 , Figure 3 and Figure 5 A first protrusion 41 and a second protrusion 42 are respectively provided at both ends of the support member 4, the first protrusion 41 is accommodated in the first mounting groove 12, and the cross-section of the first protrusion 41 is set to be larger than the opening area of ​​the first mounting groove 12 to stably connect the support member 4 and the top cover 1, and the support member 4 supports the top cover 1 through the first protrusion 41; the second protrusion 42 is located in the second mounting groove 51, and the cross-sectional area of ​​the second protrusion 42 is set to be larger than the opening area of ​​the second mounting groove 51, so as to improve the stability of the connection between the support member 4 and the sealing suction cup 5, and by providing the first protrusion 41 and the second protrusion 42, the support member 4 can better connect the top cover 1 and the sealing suction cup 5 to achieve synchronous movement of the two.

[0061] Furthermore, the second protrusion 42 is configured as a connecting plate and embedded in the second mounting groove 51 to increase the connection area between the support member 4 and the sealing suction cup 5 and enhance stability.

[0062] Furthermore, a plurality of openings 421 are arranged around the connecting plate to reduce the weight of the connecting plate and reduce the overall weight of the suction cup hook to prevent the suction cup hook from falling off due to excessive weight after adsorption, thereby making the adsorption more secure and increasing the hanging weight.

[0063] Optionally, the support member 4 is made of hard plastic / metal material to better provide support for the suction cup hook as a whole and drive the sealing suction cup 5 to move.

[0064] For details, please refer to Figure 2 , Figure 3 and Figure 4 The rotary suction cup hook also includes a sealing layer 6. The edge of the sealing suction cup 5 is connected to the fixed part 31. When the support member 4 drives the lower middle area to make axial movement relative to the fixed part 31, and the edge on the side away from the fixed part 31 is connected to the sealing layer 6, so that the sealing suction cup 5 can be firmly adsorbed after being subjected to negative pressure. The sealing layer 6 plays a role in making the sealing suction cup 5 adsorbed more firmly.

[0065] Optionally, the sealing suction cup 5 is made of PVC / soft rubber material to better deform, increase the negative pressure between the adsorption surface and the sealing suction cup 5, and enhance the adsorption force of the sealing suction cup 5.

[0066] Furthermore, the sealing suction cup 5 is provided with an annular groove 52 on the outer periphery of the area connected to the support member 4 at the side away from the fixing portion 31 , and is connected to the sealing layer 6 on the outer periphery of the annular groove 52 .

[0067] See also Figure 3 and Figure 4 A filling piece 55 is placed in the annular groove 52. The filling piece 55 can reduce the residual air between the sealing suction cup 5 and the wall, so that at the moment when the sealing suction cup 5 is close to the wall, due to the existence of the filling piece 55, no air will remain in the annular groove 52, so as to reduce the initial air volume, accelerate the formation of the negative pressure cavity, speed up the adsorption speed during installation, and enhance the stability in the initial stage of adsorption, so as to ensure the immediate exertion of the adsorption force.

[0068] Specifically, before the sealing sucker 5 is installed to the external adsorption surface, the filling piece 55 is pre-placed in the annular groove 52, and its outer surface is closely attached to the inner wall of the annular groove 52 to reduce the air volume of the sealing sucker 5 in the initial contact with the wall surface, laying the foundation for the subsequent formation of a negative pressure cavity. The existence of the filling piece 55 is like a pre-placed sealing pad, which helps to quickly remove part of the air when the sealing sucker 5 first contacts the wall surface, thereby promoting the rapid formation of negative pressure. The annular groove 52 is easily bent and expanded, thereby increasing the volume of the annular groove 52. As the annular groove 52 expands, the outer surface of the filling piece 55 that originally adheres to the inner wall of the groove gradually separates from the groove wall. This process effectively increases the cavity volume inside the sealing sucker 5 and forms a larger negative pressure cavity. At this time, due to the reduction of the air volume between the sealing sucker 5 and the adsorption surface, a large air pressure difference is quickly formed, that is, the difference between the external atmospheric pressure and the negative pressure formed inside the sealing sucker 5. This air pressure difference produces a strong inward suction force, which firmly adsorbs the sealing sucker 5 on the adsorption surface.

[0069] See also Figure 2 , Figure 3 and Figure 8 A third mounting groove 53 is formed on the side edge of the sealing suction cup 5 close to the hook body 3, and a limiting portion 313 is correspondingly provided on the hook body 3. The limiting portion 313 is located in the third mounting groove 53 to achieve the pressing of the edge area of ​​the sealing suction cup 5 by the hook body 3, so that the edge area can fit with the adsorption surface, and a closed space can be generated between the middle area of ​​the sealing suction cup 5 and the adsorption surface after the support member 4 is lifted, thereby achieving the adsorption effect of the sealing suction cup 5.

[0070] Furthermore, a protrusion 314 is provided on the side of the limiting portion 313 . When the limiting portion 313 is installed in the third installation groove 53 , the protrusion 314 abuts against the side wall of the third installation groove 53 , thereby increasing the friction force and improving the fixing effect of the limiting portion 313 on the edge of the sealing suction cup 5 .

[0071] Furthermore, the sealing layer 6 is annular and corresponds to the area where the limiting portion 313 presses the sealing suction cup 5 to improve the sealing effect.

[0072] Furthermore, a fourth mounting groove 54 is formed on the outer periphery of the sealing suction cup 5, and the sealing layer 6 is located in the fourth mounting groove 54 and is kept flush with the side of the sealing suction cup 5 close to the adsorption surface, so that the sealing suction cup 5 and the sealing layer 6 can fit tightly with the adsorption surface, thereby improving the adsorption effect.

[0073] Preferably, the sealing layer 6 is made of liquid silicone, so that the sealing layer 6 can fit more closely to the adsorption surface.

[0074] Specifically, the rotary suction cup hook also includes an elastic member 7, which is arranged between the fixed part 31 and the sealing suction cup 5 to enhance the elasticity between the fixed part 31 and the sealing suction cup 5, so as to better lift the central area of ​​the sealing suction cup 5 and provide a buffer when the sealing suction cup 5 rebounds, thereby improving the working stability of the overall structure.

[0075] Optionally, the elastic member 7 may be configured as a flower-shaped spring washer 71 / spring 72 .

[0076] Specifically, the hook body 3 also includes a connecting portion 32 and a hook 33. One end of the connecting portion 32 is fixedly connected to the fixing portion 31, and the other end is connected to the hook 33, extending the length of the hook body 3 and providing space for the hook 33, so that the user can use the hook 33 conveniently.

[0077] Furthermore, the hook 33 faces the side of the hook body 3 close to the top cover 1 , and after the sealing suction cup 5 is fixed to the adsorption surface, the hook 33 faces the opposite direction of the adsorption surface, so that the user can hang items on the hook 33 .

[0078] Preferably, the hook 33 and the connecting portion 32 are detachably connected to allow for flexible selection of the purpose of the sealing suction cup 5 and the type of the hook 33 , which is convenient for users to use.

[0079] See also Figure 3 , Fig. 9 and Fig.10 In this embodiment, a first snap-fit ​​structure 331 is provided on the hook 33, and a second snap-fit ​​structure 321 is provided at an end of the connecting portion 32 away from the fixing portion 31. The hook 33 and the connecting portion 32 are detachably connected through the first snap-fit ​​structure 331 and the second snap-fit ​​structure 321, and hooks 33 of different types and specifications are connected through the second snap-fit ​​structure 321.

[0080] Furthermore, the hook 33 is provided with a first sliding structure 332 in sequence near the connecting portion 32, and the connecting portion 32 is provided with a second sliding structure 322 in a direction away from the fixing portion 31. The hook 33 achieves relative sliding with the second sliding structure 322 through the first sliding structure 332, thereby achieving connection or release with the first locking structure 331.

[0081] Furthermore, a placement groove 323 is opened on the connecting part 32 to accommodate the hook 33. The first sliding structure 332 is placed in the placement groove 323 and the first sliding structure 332 and the second sliding structure 322 cooperate to slide, so that the hook 33 is moved to the corresponding position of the first locking structure 331 and the second locking structure 321 and is locked; and the connection between the hook 33 and the connecting part 32 can be released by sliding in the opposite direction.

[0082] In this embodiment, the first engaging structure 331 is configured as an engaging groove.

[0083] The second engaging structure 321 is configured as an engaging protrusion, and the hook 33 and the connecting portion 32 are fixed by engaging the engaging protrusion with the engaging groove.

[0084] Furthermore, a guiding slope 333 is provided on the side of the engaging groove away from the fixing portion 31. When the hook 33 slides along the first sliding structure 332 to be close to the engaging protrusion, the engaging boss abuts against the guiding slope 333. When the hook 33 continues to be pushed, the side of the connecting portion 32 away from the fixing portion 31 is slightly deformed, thereby making it easier for the engaging boss to move along the guiding slope 333 into the engaging groove. At the same time, the connecting portion 32 is reset and provides vibration tactile feedback as a signal that the installation of the hook 33 is completed.

[0085] It can be understood that through the interaction between the guiding bevel 333 and the engaging boss, smooth guidance of the installation process of the hook 33 is achieved, the accuracy and stability of the engaging process are guaranteed, direct hard collision is avoided, the wear on the engaging parts is reduced, and the service life of the engaging structure is extended; slight elastic or vibration tactile feedback can immediately inform the user that the engagement is completed, which can effectively enhance the user's interactive experience.

[0086] See also Figure 2 , Figure 7 and Fig. 9On the side of the knob 2 close to the hook body 3, a plurality of continuous limiting grooves 24 are arranged around the outer periphery of the first through hole 22, and a limiting piece 312 is correspondingly arranged on the fixing portion 31. When the knob 2 is rotated, it rotates relative to the fixing portion 31, and the limiting grooves 24 elastically deform to allow the limiting piece 312 to slide between the limiting grooves 24, so that the rotation of the knob 2 can be positioned, and feedback is obtained when the user rotates the knob 2, thereby improving the user experience. In the natural state of the rotating suction cup hook, the knob 2 can be stably fixed to the hook body 3 through the cooperation of the limiting grooves 24 and the limiting piece 312.

[0087] Furthermore, an avoidance hole 316 is opened on the periphery of the limit member 312. When the limit slot 24 slides at the limit member 312, the avoidance hole 316 provides the limit member 312 with an elastic deformation space in the direction away from the limit slot 24, thereby reducing the deformation between the limit member 312 and the limit slot 24, extending the service life of the limit member 312 and the limit slot 24, and the limit member 312 is more likely to deform, so as to reduce the force exerted by the user when rotating the knob 2, thereby facilitating operation.

[0088] Specifically, when the rotary suction cup hook is fixed on the external adsorption surface, the side where the sealing suction cup 5 is located is fitted with the external adsorption surface, and the knob 2 is turned to control the second slope 21 to push the first slope 11, so that the force applied to the knob 2 is converted into a vertical longitudinal force to drive the top cover 1 to move away from the external adsorption surface. The top cover 1 then drives the middle area of ​​the sealing suction cup 5 to move through the support member 4, and forms a closed space between the middle area of ​​the sealing suction cup 5 and the adsorption surface. The air pressure in the closed space is relatively low, forming an air pressure difference with the outside world, so that The sealing suction cup 5 is tightly adsorbed to the adsorption surface; after the buckle portion 23 is engaged with the matching portion 13, the top cover 1 drives the sealing suction cup 5 to form a closed space of maximum size, and the adsorption force of the sealing suction cup 5 on the external adsorption surface reaches the maximum, and the sealing suction cup 5 is kept stably adsorbed by the fixing of the buckle portion 23 and the matching portion 13, so that the overall adsorption of the rotating suction cup hook is stable; when the knob 2 is rotated, the limiter 312 and the limiter groove 24 cooperate with each other to provide clear hand feedback for the user's rotation control, improve the accuracy of the rotation control, and enhance the user experience. By converting the force of rotating the knob 2 into the force of pushing the top cover 1 and pulling the sealing suction cup 5, the structure is simple and convenient for user operation and control.
