Description

Technical Field

[0001] The utility model relates to the field of daily necessities, in particular to a rubber-coated suction cup assembly. Background Art

[0002] The rubber-coated suction cup usually includes an outer shell, a soft rubber disc body, and a frame for connecting the soft rubber disc body and the outer shell. The outer shell is usually provided with a hook. For example, a Chinese patent with a publication number of CN221221108U discloses a suction cup assembly, including a frame, a disc body made of soft rubber material, and an adapter. The frame is provided with a connecting portion for connecting with the adapter, and the disc body completely wraps the frame except the connecting portion, which increases the thickness of the suction cup and requires more disc body material. In view of this, the utility model proposes a rubber-coated suction cup assembly. Utility Model Content

[0003] The utility model overcomes the shortcomings of the above-mentioned technology and provides a rubber-coated suction cup assembly. In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0004] A rubber-coated suction cup assembly comprises a frame, and a soft rubber disc body which is injection-molded on the lower surface of the frame and covers the lower surface of the frame. The frame comprises an arc pressure surface made of elastic material, the arc pressure surface gradually tilts downward from the center to the periphery, the upper surface edge of the soft rubber disc body is provided with a circle of rubber-coated edges, the rubber-coated edges cover the edge of the frame, the arc pressure surface edge is provided with a plurality of deformed cuts, the rubber-coated edges are provided with connecting clips embedded in the deformed cuts, and the width of the deformed cuts at the edge of the frame is smaller than the width away from the edge of the frame.

[0005] Preferably, the deformed incision is a T-shaped incision or a cross-shaped incision, and the connecting clip is a T-shaped clip or a cross-shaped clip.

[0006] Preferably, a cross-shaped incision is provided between two adjacent T-shaped incisions.

[0007] Preferably, a suction cup shell is connected above the skeleton, a rebound protrusion is provided on the top of the rubber-coated edge, and a convex tooth for pressing a convex ring is provided on the bottom of the suction cup shell.

[0008] Preferably, the rebound protrusion is an annular protrusion.

[0009] Preferably, the arc pressing surface is evenly provided with a plurality of connection holes, and the upper surface of the soft rubber disc body is provided with connection protrusions embedded in the connection holes.

[0010] Preferably, a connecting portion for connecting to a suction cup shell is provided at the top center of the frame.

[0011] Preferably, a pressing groove is provided at the center of the lower surface of the arc pressing surface, and a rebound protrusion opposite to the pressing groove is provided on the upper surface of the soft rubber disc body.

[0012] Preferably, the thickness of the soft rubber disc body at the rebound protrusion is the smallest.

[0013] Preferably, the lower surface of the soft rubber disc body is an arc surface which gradually slopes downward from the center to the periphery.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The soft rubber plate body of the utility model is tightly connected with the frame in a semi-enclosed manner, which means that the soft rubber plate body is only enclosed on the lower surface and edge of the frame, and not on the upper surface of the frame, thereby reducing the material used to produce the soft rubber plate body and reducing the thickness of the rubber-enclosed suction cup. Moreover, the width of the deformed cutout at the edge of the frame is smaller than the width away from the edge of the frame, making it difficult for the connecting clip to separate from the deformed cutout, thereby making the frame and the soft rubber plate body firmly connected.

[0016] 2. When the user applies pressure to the suction cup shell, the suction cup shell will apply pressure to the frame through the connection part. Since the back of the connection part is provided with a pressing groove, the thickness of the pressing groove becomes thinner, which not only reduces the pressure required for the deformation of the frame, but also the rebound protrusion of the soft rubber disc fits the pressing groove. The rebound protrusion will react to the frame under the pressure of the frame, so that the user has the feeling of pressing the suction cup. At the same time, the soft rubber disc deforms with the pressure of the frame and is flattened on the wall. The convex teeth will apply pressure to the force-bearing protrusion on the edge of the soft rubber disc, increasing the pressure of the edge of the soft rubber disc on the wall, so that the edge of the soft rubber disc can fit the wall and ensure suction.

[0017] 3. A cross-shaped cutout is set between two adjacent T-shaped cutouts. The T-shaped cutout is smaller than the cross-shaped cutout. When the arc pressing surface changes from the normal state to the flattened state, the T-shaped cutout can provide a smaller deformation space for the arc pressing surface, and the cross-shaped cutout can provide a larger deformation space for the arc pressing surface, so that the arc pressing surface can be flattened as much as possible. Since the lower surface of the arc pressing surface fits the upper surface of the soft rubber disc, the arc pressing surface can be flattened, which is beneficial to the flattening of the soft rubber disc. In addition, the T-shaped cutout and the cross-shaped cutout are set at intervals to avoid problems such as too many large cuts causing the arc pressing surface edge to reduce the adsorption area with the wall, affecting the suction force of the suction cup, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0026] Reference Figure 1-6 An embodiment of a rubber-coated suction cup assembly of the utility model is proposed:

[0027] A rubber-coated suction cup assembly comprises a frame 1 and a soft rubber disc body 2 which is injection molded on the lower surface of the frame 1 and covers the lower surface of the frame 1. The frame 1 comprises an arc pressure surface 11 made of elastic material, and the arc pressure surface 11 gradually slopes downward from the center to the periphery. A circle of rubber-coated edges 23 are provided on the edge of the upper surface of the soft rubber disc body 2, and the rubber-coated edges 23 cover the edge of the frame 1. A plurality of deformation cuts are provided on the edge of the arc pressure surface 11, and a connecting clip embedded in the deformation cut is provided in the rubber-coated edges 23, and the width of the deformation cut at the edge of the frame 1 is smaller than the width away from the edge of the frame 1.

[0028] The soft rubber disc of the prior art is coated from the lower surface of the frame to the upper surface of the frame (refer to the suction cup in the background technology). Compared with the prior art, the soft rubber disc 2 of the utility model is tightly connected to the frame 1 by semi-coating, which means that the soft rubber disc 2 is only coated on the lower surface and edge of the frame 1, and not on the upper surface of the frame 1, thereby reducing the material for producing the soft rubber disc 2 and reducing the thickness of the rubber-coated suction cup. The width of the deformation cut at the edge of the frame 1 is smaller than the width away from the edge of the frame 1, making it difficult for the connecting clip to detach from the deformation cut, thereby making the frame 1 and the soft rubber disc 2 firmly connected.

[0029] like Figure 1 and Figure 2 As shown, the deformed cutout is a T-shaped cutout 12 or a cross-shaped cutout 13, and the T-shaped cutout 12 is smaller than the cross-shaped cutout 13. Figure 6 As shown, the connecting clamp is a T-shaped clamp 25 or a cross-shaped clamp 26. The T-shaped clamp 25 is embedded in the T-shaped cutout 12, and the cross-shaped clamp 26 is embedded in the cross-shaped cutout 13.

[0030] A cross-shaped cutout 13 is provided between two adjacent T-shaped cutouts 12. When the arc pressing surface 11 changes from a normal state to a flattened state, the T-shaped cutout 12 can provide a smaller deformation space for the arc pressing surface 11, and the cross-shaped cutout 13 can provide a larger deformation space for the arc pressing surface 11, so that the arc pressing surface 11 can be flattened as much as possible. Since the lower surface of the arc pressing surface 11 fits the upper surface of the soft rubber disc 2, the arc pressing surface 11 can be flattened, which is beneficial to the flattening of the soft rubber disc 2. Moreover, the T-shaped cutout 12 and the cross-shaped cutout 13 are arranged at intervals to avoid problems such as too many large cuts leading to a reduction in the adsorption area between the edge of the arc pressing surface 11 and the wall, affecting the suction force of the suction cup, and ensuring the suction strength of the suction cup.

[0031] like Figure 4 As shown, a suction cup shell 3 is connected to the top of the frame 1, a force-bearing protrusion 22 is provided on the top of the rubber-wrapped edge 23, and a protruding tooth 31 for pressing the force-bearing protrusion 22 is provided on the bottom of the suction cup shell 3.

[0032] A connecting portion 14 for connecting to the suction cup housing 3 is provided at the top center of the arc pressing surface 11. A pressing groove 15 is provided at the center of the lower surface of the arc pressing surface 11, and a rebound protrusion 22 opposite to the pressing groove 15 is provided at the top of the soft rubber disc body 2.

[0033] When the user applies pressure to the suction cup shell 3, the suction cup shell 3 will apply pressure to the frame 1 through the connecting part 14. Since a pressing groove 15 is provided on the back of the connecting part 14, the thickness at the pressing groove 15 becomes thinner, which not only reduces the pressure required for the deformation of the frame 1, but also the rebound protrusion 27 of the soft rubber disc body 2 fits the pressing groove 15. The rebound protrusion 27 is subjected to the pressure of the frame 1 and will react to the frame 1, so that the user has the feeling of pressing the suction cup.

[0034] At the same time, the soft rubber disc body 2 is deformed as the frame 1 is compressed and flattened on the wall. The convex teeth 31 will apply pressure to the force-bearing protrusions 22 on the edge of the soft rubber disc body 2, thereby increasing the pressure of the edge of the soft rubber disc body 2 on the wall, so that the edge of the soft rubber disc body 2 can fit the wall and ensure suction. Specifically, the force-bearing protrusions 22 are annular protrusions. A plurality of convex teeth 31 are arranged on the circumference of the bottom of the suction cup shell 3, so that the soft rubber disc body 2 can evenly apply pressure to the edge of the soft rubber disc body 2.

[0035] like Figure 4 As shown, the thickness of the soft rubber disc body 2 is uneven, and the thickness of the soft rubber disc body 2 at the rebound protrusion 22 is the smallest, which further reduces the pressure required to flatten the soft rubber disc body 2 and provides a better user experience.

[0036] The lower surface of the soft rubber disc body 2 is an arc surface 28 which gradually slopes downward from the center to the periphery.

[0037] like Figure 5As shown, the arc pressure surface 11 is evenly provided with a plurality of connection holes 16, and the upper surface of the soft rubber disc body 2 is provided with a connection protrusion 21, which is embedded in the connection hole 16, and can strengthen the connection between the skeleton 1 and the soft rubber disc body 2. In addition, the skeleton 1 is provided with a plurality of connection holes 16, which also reduces the material for producing the skeleton 1.

[0038] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
