[0001] The utility model relates to the field of daily necessities, in particular to a suction cup elastic component. Background Art

[0002] There are many types of suction cups on the market, including full soft rubber suction cups, rubber-coated suction cups, etc., wherein the rubber-coated suction cups usually include a shell, a soft rubber disc body, and a frame for connecting the soft rubber disc body and the shell, and the shell is usually provided with a hook. For example, a Chinese patent with publication number CN104956100A discloses a bowl-shaped skeleton vacuum suction cup, including a frame and a suction cup body, the suction cup body is coated on the bottom and top of the frame, the required suction cup body material is more, and the suction cup body is coated on the top of the frame, which increases the thickness of the suction cup. In view of this, the utility model proposes a suction cup elastic component to solve the above problems. Utility Model Content

[0023] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0024] Reference Figure 1-4 , an embodiment of a suction cup elastic component of the utility model is proposed:

[0025] A suction cup elastic component includes a frame 1 and a soft rubber disc body 2. The frame 1 includes an arc pressure surface 11 made of a high resilience material, the arc pressure surface 11 gradually tilts downward from the center to the periphery, and the bottom of the arc pressure surface 11 fits the top of the soft rubber disc body 2. The arc pressure surface 11 is evenly provided with a plurality of connection holes 12, and the top of the soft rubber disc body 2 is provided with a connection protrusion 21 embedded in the connection hole 12.

[0026] The soft rubber disc body of the prior art is covered from the bottom of the frame to the top of the frame (refer to the suction cup in the background art). Compared with the prior art, the present invention connects the frame 1 with the soft rubber disc body 2 by embedding the connecting protrusion 21 in the connecting hole 12. The soft rubber disc body 2 does not need to be covered to the top, which reduces the material for producing the soft rubber disc body 2. In addition, the frame 1 is provided with multiple connecting holes 12, which also reduces the material for producing the frame 1, thereby reducing the production cost of the suction cup. Moreover, not covering the soft rubber disc body 2 on the top of the frame 1 can also reduce the overall thickness of the suction cup elastic component.

[0027] like Figure 1 As shown, a deformation cutout 13 is provided at the edge of the arc pressing surface 11. When the arc pressing surface 11 is pressed from a normal state to a flattened state, the deformation cutout 13 leaves deformation space for the arc pressing surface 11, so that the arc pressing surface 11 can be flattened as much as possible. Since the bottom of the arc pressing surface 11 fits with the top of the soft rubber disc body 2, the arc pressing surface 11 can be flattened, which is beneficial to the flattening of the soft rubber disc body 2. Specifically, a plurality of deformation cutouts 13 are evenly arranged on the periphery of the arc pressing surface 11, so that deformation space is evenly arranged on the periphery of the arc pressing surface 11, and the material for producing the skeleton 1 can be further reduced. The deformation cutout 13 is a small deformation cutout 131 or a large deformation cutout 132. The small deformation cutout 131 can provide a smaller deformation space for the arc pressing surface 11, and the large deformation cutout 132 can provide a larger deformation space for the arc pressing surface 11. A large deformation cutout 132 is provided between two adjacent small deformation cutouts 131, and the small deformation cutouts 131 and the large deformation cutouts 132 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 pressure surface 11 and the wall, affecting the suction force of the suction cup, and ensuring the suction strength of the suction cup.

[0028] A connecting portion 14 for connecting to the suction cup housing is provided at the center of the top of the arc pressure surface 11. The connecting portion 14 is a buckle. The frame 1 is connected to the suction cup housing by the buckle, and the connection method is simple.

[0029] like Figure 2 and Figure 4 As shown, a pressing groove 15 is provided at the bottom center of the arc pressing surface 11, which can make the center of the arc pressing surface 11 thinner and easier to deform, thereby reducing the pressure required for deformation of the frame 1. A rebound protrusion 24 is provided on the top of the soft rubber disc body 2 to fit the pressing groove 15. When the user applies pressure to the suction cup shell, the suction cup shell will apply pressure to the frame 1 through the connecting part 14, and then the pressing groove 15 will apply pressure to the rebound protrusion 27. The rebound protrusion 27 will react to the pressure of the frame 1 on the frame 1, so that the user has the feeling of pressing the suction cup.

[0030] A force convex portion 16 is provided in the pressing groove 15, and a concave position 22 corresponding to the force convex portion 16 is provided on the top of the soft plastic disc body 2. When the suction cup shell is pressed on the top center of the arc pressure surface 11, the arc pressure surface 11 applies force to the soft plastic disc body 2 through the force convex portion 16, so that the soft plastic disc body 2 is deformed. Specifically, the force convex portion 16 is an annular convex portion, which can evenly apply force to the soft plastic disc body 2.

[0031] The thickness of the arc pressing surface 11 gradually decreases from the center to the periphery. From the arc pressing surface 11 close to the pressing groove 15 to the edge of the arc pressing surface 11, the thickness of the arc pressing surface 11 decreases in the range of 0.1 to 0.15 mm, which can further reduce the material used to produce the skeleton 1 and reduce the thickness of the skeleton 1.

[0032] The top edge of the soft rubber disc body 2 is provided with a rubber edge 23 wrapped around the edge of the arc pressing surface 11 , which cooperates with the connecting protrusion 21 embedded in the connecting hole 12 so that the soft rubber disc body 2 is firmly connected to the frame 1 .

[0033] 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.
