Description

Technical Field

[0001] The utility model relates to the field of suction cups, in particular to a hook, a suction cup body and a suction cup frame. Background Art

[0002] Suction cups create a vacuum chamber by pressing to displace the air inside. They utilize the pressure difference between the inside and outside of the chamber to secure household items to a base surface. They are typically attached to walls, countertops, and other surfaces for hanging items. A commonly used suction cup consists of a frame covered in rubber, with a cover attached to the outside and a connection for hooks and other attachments.

[0003] Existing suction cups are mainly divided into two types. The first is the push-on type, such as the bowl-shaped vacuum cup described in Chinese Utility Model Publication No. "CN217328064U." During use, the cup cover is manually pressed, which compresses the cup body and frame, expelling air from the cup body and forming a vacuum chamber. The rubber coating of the cup body adheres tightly to the base surface, securing it. The frame structure can be referenced for suction cup frames described in Patent Publication No. "CN217873734U." The second type is the pull-out type, such as the flat-bone suction cup described in Chinese Invention Patent Publication No. "CN103148085B." When the edge of the elastic colloid contacts the base surface, a reverse pull acts on the connecting rod, creating a low pressure inside the cup and securing it to the base.

[0004] The two existing solutions mentioned above share a common feature: the suction cup's body is constructed from a rubber-coated frame. To accommodate deformation during suction, both designs feature segmented edges, using a circumferential array of slits to separate the edges. This allows for sufficient deformation during suction. However, this structure reduces the strength of the frame's edges, making it difficult to ensure a tight seal between the suction cup's edge and the reference surface. Summary of the Invention

[0005] In order to solve the above problems, the first purpose of the present invention is to provide a suction cup frame that can meet the deformation requirements of the suction cup frame while adopting an annular sealing method in the sealing load-bearing ring area to improve the edge strength of the frame.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0007] A suction cup skeleton comprises a ring-shaped skeleton body and a connecting rod connected to the center of the back side of the skeleton body; the characteristics are: the outer edge of the skeleton body is an annular closed sealing load-bearing ring area, the skeleton body radially inside the sealing load-bearing ring area includes at least an annular deformation area; the thickness of the sealing load-bearing ring area is greater than the thickness of the annular deformation area; when an external force acts on the connecting rod to pull it axially relative to the skeleton body, the annular deformation area can be deformed.

[0008] The present invention adopts the above-mentioned technical solution, which relates to a suction cup frame. Unlike the prior art, the outer edge of this suction cup frame adopts an annular, closed, and sealed bearing ring area. That is, this sealing bearing ring area does not separate the edge of the frame by a separation seam. As a result, after the suction cup frame is encapsulated with rubber, the suction cup edge supported by the sealing bearing ring area has a higher skeleton strength, which can improve the sealing fit between the suction cup edge and the reference surface.

[0009] Furthermore, to accommodate the required deformation of the suction cup during use, this solution incorporates a thin annular deformation zone on the frame body radially inward of the sealing ring. When the suction cup frame is encapsulated with rubber, deformation stress is concentrated in the annular deformation zone.

[0010] In this way, the edge strength of the frame can be improved by adopting an annular sealing method in the sealing load-bearing ring area while meeting the deformation requirements of the suction cup frame.

[0011] In a further embodiment, the sealing load-bearing ring region has a plurality of first glue holes arranged in a circumferential array, the first glue holes extending through the upper and lower end surfaces of the sealing load-bearing ring region. In this embodiment, the plurality of first glue holes arranged in a circumferential array allow the glue to flow during the overmolding process. After the overmolding process is completed, the upper and lower end surfaces of the elastic glue are connected, thereby improving the adhesion between the elastic glue and the frame.

[0012] Preferably, the skeleton body further includes a central annular region radially inward of the annular deformation region, wherein the thickness of the central annular region is greater than that of the annular deformation region. In this embodiment, the central annular region is provided in the middle of the skeleton body primarily for connecting the rods and requires a certain strength. Therefore, the thickness of the central annular region is greater than that of the annular deformation region.

[0013] Furthermore, multiple second glue holes are spaced apart along the circumference of the annular deformation zone. The second glue holes are constructed as linear holes extending in the radial direction. In this solution, the second glue holes also allow the glue to flow during the overmolding process. After the overmolding process is completed, the upper and lower end surfaces of the elastic glue can be connected, thereby improving the adhesion between the elastic glue and the frame.

[0014] Furthermore, the second glue holes are constructed with radially arranged strip holes. The second glue holes radially arranged in the annular deformation zone can also increase the deformability of the annular deformation zone.

[0015] Preferably, the inner side of the second glue hole extends into the central ring area, so as to ensure smooth glue flow and uniform glue coating on the upper and lower sides of the central ring area.

[0016] Preferably, a central boss is further provided at the center of the central ring area, and the lower end of the connecting rod is connected to the center of the central boss.

[0017] In a more preferred embodiment, the upper end surface of at least one of the sealing force-bearing ring area, the annular deformation area, and the center ring area is provided with a plurality of protrusions arranged in an annular array along its circumference; or the upper end surface of at least one of the sealing force-bearing ring area, the annular deformation area, and the center ring area is provided with a continuous protrusion ring along its circumference. In this embodiment, the protrusions or protrusion rings are provided on at least one of the sealing force-bearing ring area, the annular deformation area, and the center ring area of the frame body. The protrusions or protrusion rings are designed to allow their upper end surfaces to be exposed from the elastic rubber layer during overmolding, thereby supporting the suction cup frame during the overmolding and injection molding process.

[0018] A second object of the present invention is to provide a suction cup body comprising a suction cup frame and an elastic colloid covering the suction cup frame; the suction cup frame comprising the above-described suction cup frame; the elastic colloid covering at least the lower end surface of the frame body and the upper end surface of the sealing load-bearing ring area. A suction cup body employing the above-described suction cup frame can enhance the edge strength of the suction cup body, ensuring a tight seal between the edge of the suction cup body and the base surface.

[0019] The third object of the present utility model is to provide a hook, comprising a suction cup body as described above. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more, unless expressly limited otherwise.

[0028] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense.

Example

[0030] like Figures 1-3 As shown, this embodiment relates to a suction cup frame, comprising a ring-shaped frame body 1 and a connecting rod 10 connected to the center of the back of the frame body 1. The outer edge of the frame body 1 is an annular closed sealing load-bearing ring area 11. The frame body 1 radially inside the sealing load-bearing ring area 11 includes an annular deformation area 12 and a central ring area 13 radially inside the annular deformation area 12.

[0031] The thickness of the sealing load-bearing annular region 11 is relatively thin, ranging from 0.5 to 0.8 cm. The thickness of the central annular region 13 is greater than that of the annular deformation region 12. The central annular region 13 is located in the middle of the skeleton body 1 and is primarily used for connecting the rods 10. It requires a certain strength, so the thickness here is greater than that of the annular deformation region 12. In a specific embodiment, a central boss 17 is further provided at the center of the central annular region 13, and the lower end of the connecting rod 10 is connected to the center of the central boss 17.

[0032] The thickness of the sealing load-bearing ring area 11 is greater than the thickness of the annular deformation area 12. When an external force acts on the connecting rod 10 to pull it axially relative to the skeleton body 1, the annular deformation area 12 can deform. Unlike the prior art, the outer edge of the suction cup skeleton adopts an annular closed sealing load-bearing ring area 11, that is, the sealing load-bearing ring area 11 does not use a separation seam to separate the edge of the skeleton. As a result, after the suction cup skeleton is encapsulated, the suction cup edge supported by the sealing load-bearing ring area 11 has a higher skeleton strength, which can improve the sealing fit between the suction cup edge and the reference surface.

[0033] Furthermore, to accommodate the required deformation of the suction cup during use, this solution features a thin annular deformation zone 12 on the frame body 1, radially inward of the sealing ring 11. When the suction cup frame is encapsulated with rubber, the deformation stress of the suction cup frame is concentrated in the annular deformation zone 12. This ensures that the required deformation of the suction cup frame is met while enhancing the frame's edge strength through the annular sealing of the sealing ring 11.

[0034] exist Figure 1 and 2 In the further embodiment shown, the sealing load-bearing ring area 11 is provided with a plurality of first glue holes 14 arranged in a circumferential array. The first glue holes 14 extend through the upper and lower end surfaces of the sealing load-bearing ring area 11. In this embodiment, the plurality of first glue holes 14 arranged in a circumferential array allow the glue to flow during the overmolding process. After the overmolding process is completed, the upper and lower end surfaces of the elastic glue are connected, thereby improving the adhesion between the elastic glue and the frame.

[0035] Furthermore, a plurality of second glue holes 15 are arranged at intervals along the circumference of the annular deformation zone 12, and the second glue holes 15 are constructed as linear holes extending in the radial direction. In the scheme here, the second glue holes 15 can also allow the flow of glue during the overmolding, and after the overmolding is completed, the connection between the upper and lower end faces of the elastic colloid can be achieved, thereby improving the degree of adhesion between the elastic colloid and the skeleton. In addition, the second glue holes 15 are constructed with radially arranged strip holes, and the second glue holes 15 radially arranged in the annular deformation zone 12 can also increase the deformability of the annular deformation zone 12. The inner side of the second glue hole 15 extends into the central annular zone 13, so that the smooth flow of glue on the upper and lower sides of the central annular zone 13 can be ensured.

[0036] In addition, the upper end surface of at least one of the sealing load-bearing ring area 11, the annular deformation area 12, and the center ring area 13 is provided with a plurality of protrusions 16 arranged in an annular array along its circumference and exposed through the elastic rubber layer. Alternatively, the upper end surface of at least one of the sealing load-bearing ring area 11, the annular deformation area 12, and the center ring area 13 is provided with a protrusion ring that is continuous along its circumference and exposed through the elastic rubber layer. In this embodiment, the protrusions 16 or protrusion ring are provided on at least one of the sealing load-bearing ring area 11, the annular deformation area 12, and the center ring area 13 of the skeleton body 1. The protrusions 16 or protrusion ring are designed to allow their upper end surface to be exposed through the elastic rubber layer during overmolding, thereby supporting the suction cup skeleton during the overmolding and injection molding process. Example

[0037] like Figure 4 and 5 As shown, this embodiment provides a suction cup body, comprising a suction cup frame 100 and an elastic colloid 2 covering the suction cup frame 100, including the suction cup frame described in Example 1. The elastic colloid 2 covers at least the lower end surface of the frame body 1 and the upper end surface of the sealing load-bearing ring area 11. A suction cup body using the suction cup frame 100 can enhance the edge strength of the suction cup body, ensuring a tight seal between the edge of the suction cup body and the base surface. Example

[0038] This embodiment provides a hook, including a suction cup body as described in Example 2.
