Description

Technical Field

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

[0002] Suction cups are widely used due to their ease of use; they only require pressing against a wall or other substrate without drilling. Modern suction cups typically consist of a frame covered with an elastic gel, with a suction cup cover placed over the gel. During use, a pressure-pressing component and a connecting rod apply pressure to the suction cup cover, forcing the elastic gel onto the suction surface. However, existing suction cup covers and suction cups lack a positioning structure, making them prone to circumferential rotation. This affects the overall suction effect and can render the suction cup unusable. Summary of the Invention

[0003] To address the shortcomings of existing technologies, a user-friendly suction cup is provided.

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

[0005] A suction cup includes a suction cup body and a frame. The frame includes a base and a pull rod disposed in the middle of the base. The suction cup body covers the outside of the frame. The suction cup body has an opening on the side connected to the top surface of the frame for the pull rod to extend out. A raised ring is disposed around the outer edge of the opening. A stop groove is uniformly disposed around the raised ring in the direction of the opening.

[0006] Preferably, the skeleton has an arc-shaped portion, which drives the suction cup body to form an exhaust space with the adsorption plane.

[0007] Preferably, the substrate includes a deformable part and a pressing part. The deformable part includes a first perforated ring disposed in the opening and a second perforated ring disposed outside the opening. The suction cup body covers the upper and lower ends of the second perforated ring. The upper and lower parts of the suction cup body are connected by a connecting post passing through the second perforated ring. The suction cup body extends outward from the second perforated ring to the edge and is fixedly connected to the skeleton.

[0008] Preferably, the first and second perforated rings are composed of a plurality of teardrop-shaped perforations.

[0009] Preferably, the perforations of the first and second perforated rings are radially staggered.

[0010] Preferably, the outer edge of the skeleton is provided with a plurality of opening slots, the openings of which face outward.

[0011] Preferably, the pressing part is horizontal on the side facing the adsorption plane.

[0012] Preferably, the tie rod is provided with threads on its exterior.

[0013] Preferably, the suction cup body is made of elastic colloid.

[0014] Compared with the prior art, this utility model prevents the suction cup and the suction cup cover from rotating circumferentially by setting a stop groove, thereby increasing the suction effect and stability of the suction cup. Attached Figure Description

[0019] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figures 1 to 4 As shown, this embodiment discloses a suction cup, including a suction cup body 100 and a frame 200. The frame 200 includes a base 210 and a pull rod 220 disposed in the middle of the base. The suction cup body 100 covers the outside of the frame 200. The suction cup body 100 has an opening 110 on the side connected to the top surface of the frame 200 for the pull rod 220 to extend out. A raised ring 120 is arranged around the outer edge of the opening 110, and a stop groove 130 is evenly formed in the direction of the opening on the raised ring 120. Therefore, when it is engaged with the suction cup cover, the suction cup and the suction cup cover cannot rotate circumferentially under the action of the stop groove 130, which increases the suction effect and stability of the suction cup.

[0022] In this embodiment: the skeleton 200 has an arc-shaped part, which drives the suction cup body 100 to form an exhaust space with the adsorption plane. When in use, pressing the suction cup will expel the air in the exhaust space, thereby forming a negative pressure between it and the adsorption plane to achieve the adsorption effect.

[0023] In this embodiment: the base 210 includes a deformable part 211 and a pressing part 212. The deformable part 211 includes a first perforated ring 213 disposed within the opening 110 and a second perforated ring 214 disposed outside the opening 110. The suction cup body 100 covers the upper and lower ends of the second perforated ring 214. The upper and lower parts of the suction cup body 100 are connected by a connecting post 101 passing through the second perforated ring 214, thereby fixing the suction cup body 100 and the frame 200. The portion of the suction cup body 100 extending outward from the second perforated ring 214 to the edge is fixedly connected to the frame 200.

[0024] In this embodiment, the first perforated ring 213 and the second perforated ring 214 are composed of a plurality of teardrop-shaped perforations.

[0025] In this embodiment, the perforations of the first hole ring 213 and the second hole ring 214 are distributed radially in an alternating manner, which ensures that the support frame has sufficient deformation capacity while its firmness is not greatly affected.

[0026] In this embodiment, the outer edge of the skeleton 200 is provided with a plurality of opening slots 230, the openings of which face outward. The design of the opening slots 230 causes the suction cup to undergo a certain deformation during the vacuum adsorption process with the external carrier, ensuring the stability of the adsorption between the two.

[0027] In this embodiment, the pressing part 212 is horizontal on the side facing the adsorption plane, so that the gas can be fully discharged during the exhaust process, forming a good negative pressure environment.

[0028] In this embodiment, the pull rod 220 is provided with threads to facilitate the connection of the drive component that drives the suction cup to move up and down.

[0029] In this embodiment, the suction cup body 100 is made of elastic colloid.

[0030] 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.
