[0002] The suction cup hook includes a suction cup part and a hook part, and the traditional suction cup part is generally composed of rubber and a pressing part. The rubber and the pressing part are fixed by a clip-on form. After the rubber fits the plane, the force exerted on the rubber plane cannot be evenly distributed on the pressing part. The rubber plane is unevenly stressed and easy to fall off. Its load-bearing capacity has room for improvement.

[0003] A rubber suction cup hook as disclosed in the patent with publication number CN202287678U includes a hook body, a bowl-shaped shell, a flat rubber suction piece and a pull rod. The bowl-shaped shell is inverted on the rubber suction piece. The bowl mouth diameter of the bowl-shaped shell is adapted to the diameter of the rubber suction piece and presses against the rubber suction piece. The bottom end of the pull rod is fixed to the center of the rubber suction piece, and the upper end passes through the bottom center of the bowl-shaped shell. The edge of the bowl mouth of the bowl-shaped shell is also provided with a limiting edge wrapped around the outer edge of the rubber suction piece. A thickened layer is provided at the connection between the center of the rubber suction piece and the pull rod.

[0004] The rubber suction piece of the above technology abuts against the bowl mouth of the bowl-shaped shell. When the hook body is subjected to force, the force exerted on the rubber suction piece cannot be evenly distributed on the bowl-shaped shell. The rubber suction piece is unevenly stressed and easily falls off. Its load-bearing capacity needs to be improved. Utility Model Content

[0007] As a further improvement of the above technical solution, it also includes a pulling rod and a knob, one end of the pulling rod is fixedly connected to the center of the rubber suction piece, and the other end of the pulling rod passes through the clamping piece and is screwed to the knob. Rotating the knob can drive the pulling rod to move forward and backward.

[0008] As a further improvement of the above technical solution, the pressing member includes a first annular portion and a cylindrical portion, the rubber suction sheet is glued to the first annular portion, the first annular portion is arranged at one end of the cylindrical portion, and the knob abuts against the other end of the cylindrical portion.

[0009] As a further improvement of the above technical solution, the locking hook includes a second annular portion and a hook portion that are integrally arranged, the hook portion is located below the second annular portion, and the pressing member is rotatably connected to the second annular portion.

[0010] As a further improvement of the above technical solution, the rubber suction piece, the pressing member, the second annular portion and the knob cooperate with each other and are arranged in sequence to form a cylindrical shape.

[0011] The beneficial effect of the utility model is that the utility model glues the edge of the rubber suction piece to the pressing piece, so that the force of the rubber suction piece can be evenly distributed to the pressing piece, reducing the risk of falling off and improving the load-bearing capacity of the suction cup hook.

[0020] Reference Figures 1 to 3 A suction cup hook includes a suction cup 1 and a hook 2 fixedly connected together. The suction cup 1 includes a rubber suction piece 11 and a pressing piece 12. The edge portion of the inner side of the rubber suction piece 11 is fixedly connected to the pressing piece 12 by bonding, so that when the rubber suction piece 11 is subjected to force, the force can be evenly distributed to the pressing piece 12, thereby improving the load-bearing capacity of the suction cup 1 and the hook 2 and reducing the risk of falling off.

[0021] In a preferred embodiment, a pulling rod 13 and a knob 14 are further included. A fixing plate 131 is provided at one end of the pulling rod 13. The fixing plate 131 is embedded in the center of the inner side surface of the rubber suction piece 11, thereby fixing the pulling rod 13 to the rubber suction piece 11. The other end of the pulling rod 13 is screwed to the knob 14. By rotating the knob 14, the pulling rod 13 is driven to move back and forth, and the pulling rod 13 drives the rubber suction piece 11, so that the rubber suction piece 11 is adsorbed on the external plane. As the number of rotations increases, the adsorption force will show a trend of continuous increase.
