Detailed Implementation

[0028] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments thereof. Please refer to... Figures 1 to 3 One embodiment of this utility model provides a knob-type suction cup device, comprising:

[0029] The fixed base 10 is provided with several upper and lower guide structures 11.

[0030] The suction cup 20 is located at the bottom of the fixed base 10. The top of the suction cup 20 is provided with a vertical movable part 21, which slides in cooperation with the vertical guide structure 11. The side of the vertical movable part 21 is provided with several driving engagement parts 22. The vertical guide structure 11 restricts the vertical movable part 21 from rotating relative to the fixed base 10 and only allows it to move up and down.

[0031] The knob 30 is rotatably engaged with the fixed base 10 and is arranged around the upper and lower movable parts 21. The inner side of the knob 30 is provided with several drive rails 31 that extend spirally around the rotation axis of the knob 30. The drive engagement part 22 is slidably engaged with the drive rails 31.

[0032] The working principle of a knob-type suction cup device according to an embodiment of this utility model is explained below:

[0033] When it is necessary to adhere to a fixed position, the suction cup 20 is placed against the fixed position, and then the knob 30 is rotated at a certain angle, so that the drive mating part 22 moves upward along the drive track 31 on the knob 30, thereby causing the upper and lower movable parts 21 to move upward along the upper and lower guide structure 11. Part of the suction cup 20 is restricted by the fixed seat 10 and will not move, while the part of the suction cup 20 connected to the upper and lower movable parts 21 will deform upward, so that a vacuum cavity is formed between the suction cup 20 and the fixed position, thus completing the adsorption mating between the suction cup 20 and the fixed position.

[0034] When it is necessary to remove the suction, turn the knob 30 back to a certain angle so that the drive engagement part 22 moves downward along the drive track 31 on the knob 30, thereby causing the upper and lower movable parts 21 to move downward along the upper and lower guide structure 11. The deformed part of the suction cup 20 will move toward the fixed position to restore its shape, and then the suction cup 20 can be removed from the fixed position.

[0035] In this embodiment, the knob 30 is rotated 90° to switch the adsorption and desorption of the suction cup 20. Of course, the rotation angle of the knob 30 is determined according to the shape of the drive track 31.

[0036] Please see Figures 2-3 The specific structure of the fixing base 10 can be designed according to actual needs. For example, in some optional embodiments, the fixing base 10 includes an upper fixing member 12 and a lower fixing member 13, an upper and lower guide structure 11 is connected between the upper fixing member 12 and the lower fixing member 13, an upper and lower movable member 21 is movably disposed between the upper fixing member 12 and the lower fixing member 13, a suction cup 20 is disposed at the bottom of the lower fixing member 13, and the upper fixing member 12 and the lower fixing member 13 cooperate to limit the movement range of the upper and lower movable member 21.

[0037] The specific structure of the upper and lower guide structure 11 can be designed according to actual needs. For example, in some optional embodiments, the upper and lower guide structure 11 is a guide post, and the upper and lower movable parts 21 slide in cooperation with the guide post, so that the upper and lower movable parts 21 can slide stably up and down. In this embodiment, multiple guide posts are provided between the upper fixed part 12 and the lower fixed part 13.

[0038] Please see Figure 5In some optional embodiments, a positioning groove 32 is provided at the bottom of the end of the drive track 31. When it is necessary to attach to a fixed position, the suction cup 20 is placed against the fixed position, and then the knob 30 is rotated at a certain angle, so that the drive engagement part 22 moves upward along the drive track 31 on the knob 30, so that the upper and lower movable parts 21 move upward to the predetermined position under the drive of the knob 30. At this time, the drive engagement part 22 is positioned and engaged with the positioning groove 32. Since the suction cup 20 undergoes elastic deformation at this time, the elastic force of the suction cup 20 is downward, so the upper and lower movable parts 21 are pulled downward, thereby keeping the drive engagement part 22 pressed in the positioning groove 32. When it is necessary to release the suction cup 20, it is only necessary to apply a certain force to make the drive engagement part 22 disengage from the positioning groove 32.

[0039] In some optional embodiments, the knob 30 is provided with a plurality of first toothed grooves 33 evenly arranged around the rotation axis of the knob 30, and the fixing base 10 is provided with a plurality of first spring clips 14. The first spring clips 14 extend into the first toothed grooves 33. When the knob 30 is rotated, the first spring clips 14 continuously switch between extending into each of the first toothed grooves 33, thereby producing a "clicking" sound, which helps to improve the user experience. In this embodiment, the upper fixing member 12 is provided with a plurality of first spring clips 14.

[0040] To improve the stability of the movement of the upper and lower movable parts 21, in some optional embodiments, the upper and lower movable parts 21 are provided with a plurality of driving engagement parts 22 on their sides. The plurality of driving engagement parts 22 are evenly arranged around the upper and lower movable parts 21, and the knob 30 is provided with a plurality of driving rails 31, and the driving engagement parts 22 and the driving rails 31 are correspondingly slidably engaged.

[0041] In some alternative embodiments, a rotating cover 15 is rotatably provided on the fixed base 10, which can improve the aesthetics.

[0042] Please see Figure 6 In some optional embodiments, the rotating cover 15 is provided with a plurality of second toothed grooves 16 evenly arranged around the rotation axis of the rotating cover 15, and the fixing base 10 is provided with a plurality of second spring-loaded latches 17, which extend into the second toothed grooves 16. When the rotating cover 15 rotates, the second spring-loaded latches 17 continuously switch between extending into each of the second toothed grooves 16, thereby producing a "clicking" sound, which helps to improve the user experience. In this embodiment, the upper fixing member 12 is provided with a plurality of second spring-loaded latches 17.

[0043] In some alternative embodiments, the rotating cover 15 is detachably connected to the cover fixing member 18, and part of the fixing base 10 is restricted between the rotating cover 15 and the cover fixing member 18, thereby facilitating the installation of the rotating cover 15. In this embodiment, the rotating cover 15 is disposed above the upper fixing member 12, and the cover fixing member 18 is disposed below the upper fixing member 12, thereby rotating the position of the rotating cover 15.

[0044] In some optional embodiments, the rotating cover 15 is provided with a bracket fixing structure (not shown). The bracket fixing structure can be a ball joint structure or a rigid rod structure, etc. The ball joint structure or rigid rod structure can be connected to a structure for clamping devices such as mobile phones or cameras. Of course, the specific structure of the bracket fixing structure is not limited to this.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
