[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] Example 1

[0030] refer to Figures 1 to 4 ,like Figures 1 to 4 The suction cup skeleton shown includes a pull plate 10 and a pull rod 11 connected to the pull plate 10. The pull rod 11 is cylindrical and has a positioning plane 111 on its outer cylindrical wall. The outer cylindrical wall of the pull rod 11 has a thread 112. The positioning plane 111 has a hinge hole 113 that penetrates the pull rod 11 in the radial direction. The hinge hole 113 is located at the end of the pull rod 11 away from the pull plate 10. The outer edge of the pull plate 10 facing away from the pull rod 11 has a bowl-shaped skeleton plate 12. The opening of the skeleton plate 12 faces away from the pull rod 11. The pull rod 11, the pull plate 10, and the skeleton plate 12 are integrally injection molded. The thickness of the skeleton plate 12 is less than the thickness of the pull plate 10.

[0031] In the above structure, by setting a thread 112 on the pull rod 11 to make it compatible with the screw handle, and setting a positioning plane 111 and a hinge hole 113 to make it compatible with the eccentric handle, only one set of molds needs to be developed to make the pull rod 11 compatible with both the screw handle and the eccentric handle, effectively reducing production costs and increasing the flexibility and freedom of later assembly; the pull rod 11, the pull plate 10, and the skeleton plate 12 are integrally injection molded, which has the advantages of high connection strength and large contact area.

[0032] In this embodiment, the skeleton disk 12 is provided with a plurality of through-hole attachment grooves 121, which are arranged at intervals along the circumferential direction of the skeleton disk 12 and are also opened in the radial direction.

[0033] In the above structure, the adhesion groove 121 is used to improve the adhesion between the groove and the disc body 20 during the later manufacturing process.

[0034] In this embodiment, the skeleton disk 12 is further provided with a plurality of through-hole outer edge grooves 122. The outer edge grooves 122 are located outside the attachment grooves 121, are arranged at intervals along the circumferential direction of the skeleton disk 12, and are opened to the outer edge of the skeleton disk 12 in the radial direction.

[0035] In the above structure, since the diameter of the skeleton disk 12 is much larger than that of the pull plate 10 of the traditional disk skeleton, the deformation at the outer edge will increase during adsorption deformation. The outer edge groove 122 opened in the radial direction to the outer edge of the skeleton disk 12 can expand the skeleton disk 12 to reduce stress when the suction cup adsorbs.

[0036] In this embodiment, a plurality of through-hole intermediate grooves 123 are provided between adjacent outer edge grooves 122, and the intermediate grooves 123 are opened along the radial direction of the skeleton disk 12 to near the outer edge of the skeleton disk 12.

[0037] In the above structure, the intermediate groove 123 can effectively ensure the adhesion between the outer edge of the skeleton disk 12 and the disk body 20.

[0038] In this embodiment, the outer edge groove 122 is opened towards the outer edge of the skeleton disk 12 and is inclined in a clockwise or counterclockwise direction; the middle groove 123 is opened towards the outer edge of the skeleton disk 12 and its inclination direction is the same as that of the outer edge groove 122.

[0039] In the above structure, the inclined outer edge groove 122 and the middle groove 123 can further weaken the rigidity of the outer edge of the skeleton disk 12, increase its flexibility, and make it easier to deform during adsorption while ensuring the connection strength between it and the disk body 20.

[0040] In this embodiment, the side of the skeleton disk 12 facing away from the disk opening is also provided with a plurality of positioning protrusions 124 that protrude outward toward the pull rod 11 and are spaced apart along the circumferential direction of the skeleton disk 12.

[0041] In the above structure, the positioning protrusion 124 protrudes from the disk body 20 after the disk body 20 is manufactured, which helps to improve the connection strength between it and the disk body 20.

[0042] In this embodiment, the positioning protrusion 124 is located at the junction of the adjacent attachment groove 121 and the outer edge groove 122.

[0043] In this embodiment, there are two positioning planes 111, which are spaced 180 degrees apart along the circumferential direction of the pull rod 11, and the two ends of the hinge hole 113 are located at each positioning plane 111.

[0044] In the above structure, the axis of the hinge hole 113 is perpendicular to the axis of the positioning plane 111 and the axis of the pull rod 11.

[0045] Example 2

[0048] In this embodiment, the side of the disk body 20 corresponding to the opening of the skeleton disk 12 is provided with an adhesive layer 21.

[0049] In the above structure, the adhesive layer 21 can improve adsorption and adhesion strength, and at the same time help to improve the airtightness with the surface of the adsorbed object; the adhesive layer 21 is silicone or anti-slip adhesive.

[0050] The above description is only a preferred embodiment of the present utility model.
