Technical Field

[0001] This utility model relates to the field of fixing device technology, and in particular to a suction cup fixing device. Background Technology

[0002] Suction cups are widely used due to their ease of use; they only require pressing against a wall or other flat surface without drilling. However, existing suction cup fixing devices lack a positioning structure between the suction cup and its cover. During operation, the suction cup and its cover can easily rotate, affecting the overall suction effect and resulting in low load-bearing capacity and durability. Summary of the Invention

[0003] To address the shortcomings of existing technologies, a suction cup fixing device with good adsorption effect is provided.

[0004] This utility model is achieved using the following technical solution:

A connecting rod is connected upward to the center of the top surface of the suction cup, and a stop groove is provided around the connecting rod. A positioning hole for the connecting rod to extend is provided in the center of the suction cup cover. The bottom surface of the suction cup cover forms an active space for at least part of the suction cup to move. A stop block ring is provided around the outer edge of the active space. The stop block ring is embedded in the stop groove so that the suction cup cover cannot rotate relative to the suction cup.

One end of the telescopic spring abuts against the movable groove, and the other end abuts against the prompting element. The inner wall of the rotating cover is surrounded by toothed grooves. The prompting element extends outward from the opening to the contact joint. The contact joint emits a prompting sound when the adjacent toothed groove moves.

[0009] Preferably, the top of the prompting element is provided with an anti-detachment block to prevent it from falling off.

[0010] Preferably, the bottom surface of the suction cup cover is concentrically provided with a first pressure ring and a second pressure ring on the outer side of the stop block ring, and the height of the stop block ring, the first pressure ring and the second pressure ring increases sequentially from the center of the suction cup cover outward.

[0022] Example

[0023] like Figures 1 to 6As shown, this embodiment discloses a suction cup fixing device, including a suction cup 100, a suction cup cover 200, and a driving member 300 that drives the suction cup 100 to at least partially approach or move away from the adsorption plane. A connecting rod 130 is connected upward to the center of the top surface of the suction cup 100, and a stop groove 140 is provided around the connecting rod 130. A positioning hole 210 for the connecting rod 130 to extend is provided in the center of the suction cup cover 200. The bottom surface of the suction cup cover 200 forms an active space for at least part of the suction cup 100 to move. A stop block ring 220 is provided around the outer edge of the active space. The stop ring block 220 is embedded in the stop groove 140 so that the suction cup cover 200 cannot rotate relative to the suction cup 100. Thus, during the adsorption process, the suction cup cover 200 can always keep the suction cup 100 pressed, so that the overall adsorption effect of the suction cup fixing device remains stable and the adsorption force is improved.

[0024] In this embodiment: the outer wall of the connecting rod 130 is provided with a guide groove 131, and the inner wall of the positioning hole 210 is provided with a guide block 211. The guide block 211 is embedded in the guide groove 131 and slides along the length direction of the guide groove 131, thereby preventing the suction cup cover 200 from rotating relative to the suction cup 100 during operation and improving the adsorption stability of the suction cup fixing device.

[0025] In this embodiment: the driving component 300 is a rotating cover, which includes a body 310 and a connecting hole 320 connected to the connecting rod 130. The connecting hole 320 is provided with an internal thread, and the connecting rod 139 is provided with an external thread. Through the cooperation of the internal thread and the external thread, the driving component 300 drives the suction cup 100 to lift at least partially and form a negative pressure between it and the adsorption plane to achieve the adsorption effect.

[0026] In this embodiment: A rotation prompting device is provided on the suction cup cover 200. The rotation prompting device includes a prompting element 230 and a telescopic spring 240. The side wall and bottom wall of the suction cup cover 200 form a movable groove for the rotation prompting device to move. The side arm of the suction cup cover has an opening that communicates with the movable groove. One end of the telescopic spring 230 abuts against the movable groove, and the other end abuts against the prompting element 239. The inner wall of the rotating cover is surrounded by toothed grooves 330. The prompting element 230 extends outward from the opening to the contact joint 231. The contact joint 231 emits a prompting sound when the adjacent toothed grooves 330 move, reminding the user whether the rotation is in place.

[0027] In this embodiment: the top of the prompting element 230 is provided with an anti-detachment block 232 to prevent it from falling off.

[0028] In this embodiment: the bottom surface of the suction cup cover 200 is concentrically provided with a first pressure ring 250 and a second pressure ring 260 on the outer side of the stop block ring 220. The height of the stop block ring 220, the first pressure ring 250 and the second pressure ring 260 increases sequentially from the center of the suction cup cover 200 outward, thereby forming a multi-level pressing to ensure the sealing of the suction cup during the adsorption process, prevent air leakage and affect the adsorption effect.

[0029] Preferably, the suction cup 100 includes a suction cup body 110 and a frame 120. The suction cup body 110 covers and is fixed to the frame 120. A protruding ring extends upward from the top surface of the suction cup body 110, and the stop grooves 140 are evenly distributed on the protruding ring. It is understood that the suction cup body 110 is generally supported by an elastic colloid, and the frame 120 is generally made of plastic.

[0030] In this embodiment, the connecting rod 130 is connected to an extension piece 400, which is used to connect other functional accessories such as hooks, hanging rods, and towel racks to increase the usage scenarios.

[0031] In this embodiment: the connecting rod 130 is provided with an insertion hole 132 arranged along the length direction, and the side wall of the connecting rod 130 is provided with a locking hole 133 communicating with the insertion hole 132, so as to facilitate the fixing of the extension 400.

[0032] In this embodiment, a hanging ring 500 is rotatably connected to the suction cup cover 200 for connecting decorative parts.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
