[0040] Refer to the attached drawings of the specification of this utility model Figures 1 to 8 A hook with a suction cup device (hereinafter referred to as "suction cup") according to a preferred embodiment of the utility model will be disclosed and explained in the following description, wherein the hook includes a suction cup device 10 and a hook body device 20, the hook body device 20 is installed on the suction cup device 10, the suction cup device 10 can be adsorbed on the wall, and the hook body device 20 is used to hang and store items.

[0041] refer to Figure 1 and Figure 2 The hook can be deformed and used according to different usage scenarios. For example, the hook device 20 further includes an arm 21 and a hook body 22 rotatably mounted on one end of the arm 21, and the other end of the arm 21 is mounted on the suction cup device 10. The hook can be deformed by rotating the hook body 22 to meet the user's usage needs in different scenarios.

[0042] refer to Figures 3 to 6The suction cup device 10 includes a suction cup body 11 and a cover shell 12, wherein the suction cup body 11 includes a suction cup 111 and a connecting rod 112, one end of the connecting rod 112 is arranged on one side of the suction cup 111, and the other side of the suction cup 111 can be close to the wall, wherein the cover shell 12 has a cover channel 121 and a support arm 122, one end of the connecting rod 112 away from the suction cup 111 passes through the cover channel 121 of the cover shell 12, and the support arm 122 supports the edge of the suction cup 111. Through the above structure, on the one hand, when the user presses the suction cup 111 of the suction cup body 11 against the wall, the support arm 122 can apply pressure to the suction cup 111 and discharge the air between the suction cup 111 and the wall, so that the suction cup 111 is firmly attached to the wall; on the other hand, in order to enhance the firmness of the suction cup 111 adsorbed on the wall, the middle part of the suction cup 111 is pulled away from the wall by pulling the connecting rod 112 in a direction away from the wall, so that a negative pressure cavity is formed between the middle part of the suction cup 111 and the wall, thereby enhancing the firmness of the suction cup 111 adsorbed on the wall. The adsorption force between the suction cup 111 and the wall enables the suction cup 111 to be more firmly adsorbed on the wall; on the other hand, the support arm 122 is annular. When the connecting rod 112 is pulled in a direction away from the wall to make the middle part of the suction cup 111 leave the wall, the support arm 122 presses against the edge of the suction cup 111 to prevent the edge of the suction cup 111 from being displaced or even detached from the wall, so as to effectively prevent outside air from entering the negative pressure cavity formed between the suction cup 111 and the wall, thereby increasing the stability and firmness of the suction cup device 10.

[0043] Furthermore, the suction cup 111 is made of rubber material, so that the suction cup 111 is deformable, so that when the connecting rod 112 is pulled to move in a direction away from the wall, the connecting rod 112 can pull the suction cup 111 to deform, so that the middle part of the suction cup 111 leaves the wall, thereby forming a negative pressure cavity between the middle part of the suction cup 111 and the wall. Accordingly, when the suction cup 111 can restore its initial state to make the negative pressure cavity formed between the middle part of the suction cup 111 and the wall disappear, the suction cup 111 can pull the connecting rod 112 to move in a direction close to the wall.

[0044] It is worth mentioning that the connection method of the suction cup 111 and the connecting rod 112 is not limited in the hook of the utility model. Figures 3 to 6 The suction cup 111 and the connecting rod 112 are integral, that is, the connecting rod 112 integrally extends outward from one side of the suction cup 111 .

[0045] Continue to refer to the attached Figures 3 to 6The housing 12 includes a ring arm 123 and a support bottom surface 124, and the housing 12 has an activity space 125. The ring arm 123 integrally extends from the periphery of the support bottom surface 124 in a direction perpendicular to the support bottom surface 124. The activity space 125 is formed between the ring arm 123 and the support bottom surface 124. The support arm 122 is disposed on the support bottom surface 124 and surrounded by the ring arm 123. The height of the support arm 122 is smaller than the height of the ring arm 123. The suction cup 111 is accommodated in the activity space 125. In other words, the ring arm 123 surrounds the outer side of the suction cup 111, so that the ring arm 123 can protect the suction cup 111 and make the hook more aesthetically pleasing. Preferably, the ring arm 123 has a notch 1231 on two opposite sides respectively, and when the suction cup device 10 is adsorbed on the wall, there is a gap between the ring arm 123 and the wall, so that when the suction cup device 10 needs to be removed from the wall, the notch 1231 of the ring arm 123 is convenient for the user to apply force.

[0046] Reference Figure 5 and Figure 6 The suction cup device 10 includes an elastic element 13 , one end of the elastic element 13 abuts against the suction cup 111 , and the other end abuts against the supporting bottom surface 124 of the cover shell 12 . The elastic element 13 is accommodated in the activity space 125 of the cover shell 12 . When the connecting rod 112 is pulled to move in a direction away from the wall so that the middle part of the suction cup 111 leaves the wall, the suction cup 111 squeezes the elastic element 13 in the direction of the supporting bottom surface 124 close to the cover shell 12 due to the middle part leaving the wall, so that the elastic element 13 is deformed and accumulates elastic potential energy. When the external force pulling the connecting rod 112 in the direction away from the wall is removed, the elastic element 13 automatically resets to push the middle part of the suction cup 111 to move in a direction close to the wall so that the negative pressure cavity formed between the middle part of the suction cup 111 and the wall disappears, thereby facilitating the user to remove the suction cup device 10 from the wall. In this process, the suction cup 111 pulls the connecting rod 112 to move in a direction close to the wall.

[0047] Preferably, the elastic element 13 is mounted on the connecting rod 112 to stably maintain the elastic element 13 in the movable space 125 of the cover shell 12 to prevent the elastic element 13 from tilting, so that one end of the elastic element 13 can reliably abut against the suction cup 111 and the other end can reliably hit the supporting bottom surface 124 of the cover shell 12, and the suction cup device 10 has good stability during use.

[0048] Continue to refer to the attached Figures 3 to 6The suction cup device 10 includes a pin 14 and a driving body 15, wherein the driving body 15 includes a driving portion 151 and at least one pushing portion 152, the pushing portion 152 is arranged on the side of the driving portion 151, the driving portion 151 has a driving portion channel 1511 and two driving surfaces 1512, the two driving surfaces 1512 are symmetrically arranged on opposite sides of the driving portion channel 1511, and the end of the connecting rod 112 away from the suction cup 111 passes through the driving portion 1511. The driving portion 151 is provided with a mounting hole 1121 at one end of the connecting rod 112 away from the suction cup 111, and the middle part of the pin shaft 14 is mounted in the mounting hole 1121 of the connecting rod 112, so that the pin shaft 14 is arranged at the end of the connecting rod 112 away from the suction cup 111, and the two ends of the pin shaft 14 form a driven end 141 respectively, and the two driven ends 141 are respectively supported by the two driving surfaces 1512 of the driving portion 151. When the user pushes the push portion 152 to change the horizontal position of the driving portion 151, the two driven ends 141 of the pin shaft 14 move from one end of the driving surface 1512 to the other end along the two driving surfaces 1512 of the driving portion 151 respectively, restricted by the housing channel 121 of the housing 12 and the driving portion channel 1511 of the driving portion 151.

[0049] That is to say, the shell channel 121 of the cover shell 12 and the driving part channel 1511 of the driving part 151 are used to limit the movement direction of the connecting rod 112 to prevent the connecting rod 112 from moving or tilting in the horizontal direction, that is, the shell channel 121 of the cover shell 12 and the driving part channel 1511 of the driving part 151 limit the movement direction of the connecting rod 112 in the height direction, so that when the user pushes the pushing part 152 to change the horizontal position of the driving part 151, the two driven ends 141 of the pin shaft 14 respectively move from one end of the driving surface 1512 to the other end along the two driving surfaces 1512 of the driving part 151.

[0050] It is worth mentioning that, in the hook of the present invention, the horizontal direction is a direction parallel to the wall surface, and the height direction is a direction perpendicular to the wall surface.

[0051] Specifically, one of the two ends of the driving surface 1512 of the driving portion 151 is a low end 1513, and the other is a high end 1514, that is, there is a height difference between the low end 1513 and the high end 1514 of the driving surface 1512. When the driven end 141 of the pin 14 moves from the low end 1513 to the high end 1514 along the driving surface 1512 of the driving portion 151, the connecting rod 112 is pulled to move in a direction away from the wall, and the connecting rod 112 pulls the middle part of the suction cup 111 away from the wall, so as to form a negative pressure cavity between the middle part of the suction cup 111 and the wall, thereby enhancing the adsorption force between the suction cup 111 and the wall. Correspondingly, when the elastic element 13 is reset to push the middle part of the suction cup 111 toward the direction close to the wall so that the negative pressure cavity formed between the middle part of the suction cup 111 and the wall disappears, the suction cup 111 pulls the connecting rod 112 toward the direction close to the wall, and the driven end 141 of the pin shaft 14 moves from the high end 1514 to the low end 1513 along the driving surface 1512 of the driving part 151.

[0052] Preferably, the inner diameter of the mounting hole 1121 of the connecting rod 112 is larger than the outer diameter of the pin shaft 14, and the pin shaft 14 is rotatably mounted on the mounting hole 1121 of the connecting rod 112, so that the driven end 141 of the pin shaft 14 can roll from the lower end 1512 to the higher end 1514 along the driving surface 1512 of the driving part 151, so that the user can save effort when pushing the pushing part 152.

[0053] Furthermore, the high ends 1514 of the two driving surfaces 1512 of the driving portion 151 respectively have a limiting groove 1515. After the two driven ends 141 of the pin shaft 14 roll to the high ends 1514 corresponding to the driving surfaces 1512, the elastic element 13 pushes the middle part of the suction cup 111 to move toward the direction close to the wall. Therefore, the two driven ends 141 of the pin shaft 14 can automatically enter and be reliably retained in the two limiting grooves 1515 of the driving portion 151 to prevent the two driven ends 141 of the pin shaft 14 from slipping off the high ends 1514 of the driving surfaces 1512, thereby ensuring that a negative pressure cavity is maintained between the suction cup 111 and the wall, so that the suction cup device 10 is more firmly adsorbed on the wall.

[0054] like Figures 5 to 8 As shown, in this specific example of the hook of the utility model, the driving surface 1512 of the driving portion 151 is a straight inclined surface. Fig. 9In the specific example of the hook shown, the driving surface 1512 of the driving portion 151 is a concave arc surface. Fig.10 In the specific example of the hook shown, the driving surface 1512 of the driving portion 151 is an outwardly convex arc surface.

[0055] Further, please refer to the attached Figure 7 and Figure 8 The driving portion 151 has a boss 1516, and the boss 1516 protrudes around the driving surface 1512. When the two driven ends 141 of the pin shaft 14 slide between the lower end 1513 and the high end 1514 along the driving surface 1512 of the driving portion 151, the boss 1516 can prevent the pin shaft 14 from slipping out of the mounting hole 1121 of the connecting rod 112, thereby improving the stability of the suction cup device 10.

[0056] Continue to refer to the attached Figures 3 to 8 The support bottom surface 124 has at least one slideway 1241, and the push portion 152 is movably disposed on the slideway 1241, so that the moving direction and sliding range of the push portion 152 are limited by the slideway 1241. Preferably, the number of the slideways 1241 of the support bottom surface 124 is two, and the two slideways 1241 are symmetrical with respect to the housing channel 121. Correspondingly, the number of the push portions 152 of the driving body 15 is two, and the two push portions 152 are symmetrical with respect to the driving body 151, and each of the push portions 152 is movably disposed on each of the slideways 1241, respectively. The two slideways 1241 limit the sliding range of the driving body 15 when it slides back and forth, and can prevent the driving body 15 from rotating.

[0057] For ease of understanding, the two slides 1241 of the supporting bottom surface 124 are respectively defined as a left slide 1241a and a right slide 1241b, and the left slide 1241a and the right slide 1241b are symmetrical with respect to the cover channel 121, and the two push parts 152 of the driving body 15 are respectively defined as a left push part 152a and a right push part 152b, and the left push part 152a and the right push part 152b are symmetrical with respect to the driving part 151, wherein the left push part 152a and the right push part 152b are respectively slidably arranged on the left slide 1241a and the right slide 1241b of the supporting bottom surface 124, and the left slide 1241a limits the moving direction and sliding range of the left push part 152a, and the right slide 1241b limits the moving direction and sliding range of the right push part 152b. Reference Figure 1 and Figure 2 The support arm 21 of the hook device 20 has an avoidance space 211, the position of the avoidance space 211 corresponds to the position of the slide 124, and the pushing portion 152 of the driving body 15 is slidably arranged in the avoidance space 211 of the support arm 21, wherein when the pushing portion 152 of the driving body 15 slides along the slide 1241 of the supporting bottom surface 124, the avoidance space 21 of the support arm 21 can avoid the pushing portion 152 and further prevent the driving body 12 from rotating, thereby improving the stability of the hook.

[0058] It is worth mentioning that the specific manner in which the support arm 21 is mounted on the housing 12 is not limited in the hook of the present invention. Figure 3 and Figure 4 The support bottom surface 124 of the cover shell 12 has a plurality of assembly holes 1242, and the support arm 21 has a plurality of assembly arms 212. The outer side of the assembly arm 212 has a hook platform 2121. When the assembly arm 212 of the support arm 21 begins to be inserted into the assembly hole 1242 of the support bottom surface 124, the inner wall of the support bottom surface 124 for forming the assembly hole 1242 squeezes the hook platform 2121 of the assembly arm 212, so that the assembly arm 212 is deformed. After the assembly arm 212 of the support arm 21 is inserted into the assembly hole 1242 of the support bottom surface 124, the assembly arm 2121 returns to its initial state and allows the hook platform 2121 to hook the edge of the assembly hole 1242 of the support bottom surface 124, thereby installing the support arm 21 on the cover shell 12.

[0059] The process of fixing the hook to the wall is as follows: first, when the user presses the cover 12 in such a way that the suction cup 111 is attached to the wall, the air between the suction cup 111 and the wall is discharged, so that the suction cup device 10 is adsorbed to the wall; secondly, when the user pushes the left push portion 152a to the right, on the one hand, the left push portion 152a and the right push portion 152b slide to the right along the left slide 1241a and the right slide 1241b of the supporting bottom surface 124 of the cover 12 respectively, and on the other hand, due to the cover The housing channel 121 of the drive unit 151 and the drive unit channel 1511 of the drive unit 151 limit the movement direction of the connecting rod 112 in the height direction, and the middle part of the pin shaft 14 is arranged at the end of the connecting rod 112 away from the suction cup 111, so that as the horizontal position of the drive unit 151 changes, the driven end 141 of the pin shaft 14 slides from the low end 1513 to the high end 1514 along the driving surface 1512 of the drive unit 151. It can be understood that at the driven end 141 of the pin shaft 14 During the sliding process from the lower end 1513 to the higher end 1514 along the driving surface 1512 of the driving portion 151, the connecting rod 112 moves in a direction away from the wall to pull the middle part of the suction cup 111 away from the wall and form a negative pressure cavity between the suction cup 111 and the wall. At the same time, the suction cup 111 squeezes the elastic element 13 in a direction close to the supporting bottom surface 124, so that the elastic element 13 is deformed and accumulates elastic potential energy. Again, when the two driven ends 141 of the pin shaft 14 move to the positions corresponding to the driving portion 151, the connecting rod 112 moves in a direction away from the wall to pull the middle part of the suction cup 111 away from the wall and form a negative pressure cavity between the suction cup 111 and the wall. When the two limiting grooves 1515 of 151 are in position, since the elastic element 13 pushes the middle part of the suction cup 111 to move toward the wall, the two driven ends 141 of the pin shaft 14 can automatically enter and be reliably retained in the two limiting grooves 1515 of the driving portion 151, so as to prevent the two driven ends 141 of the pin shaft 14 from slipping off from the high end 1514 of the driving surface 1512, thereby ensuring that a negative pressure cavity is maintained between the suction cup 111 and the wall, so that the suction cup device 10 is more firmly adsorbed on the wall.

[0060] The process of removing the hook from the wall is as follows: first, when the user pushes the right push portion 152b to the left, on the one hand, the left push portion 152a and the right push portion 152b slide to the left along the left slide 1241a and the right slide 1241b of the supporting bottom surface 124 of the cover shell 12 respectively; on the other hand, the elastic element 13 pushes the middle part of the suction cup 111 to move toward the direction close to the wall during the resetting process, so that the negative pressure cavity formed between the middle part of the suction cup 111 and the wall disappears. In this process, the suction cup 111 pulls the connecting rod 112 to move toward the direction close to the wall. As the horizontal position of the driving part 151 changes, the driven end 141 of the pin shaft 14 slides from the high end 1514 to the low end 1513 along the driving surface 1512 of the driving part 151; again, the user's fingers can apply force to the cover shell 12 at the position of the notch 1231 of the ring arm 123 of the cover shell 12 to allow the suction cup device 10 to detach from the wall, thereby removing the hook from the wall.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments.
