Description

Technical Field

[0001] The utility model relates to the technical field of suction cup hooks, in particular to a suction cup device and a suction cup hook. Background Art

[0002] Currently, there are some hooks on the market for hanging washbasins, towels, bath bombs and other daily necessities. For example, Chinese patent application number 202223019512.1 discloses a suction cup fixed basin hook, which includes a hook that can be fixed to an external base surface and a suction cup connected to the hook. The suction cup includes a plate body, a frame and a plate cover. The plate body is covered on the frame, and the frame is provided with a connecting portion.

[0003] When the suction cup of the above suction cup is in use, the suction cup is directly pressed on the glass or wall to achieve adsorption. However, the adsorption force of this type of suction cup is relatively small, so heavy objects cannot be hung on the hook, otherwise the entire hook will fall off the wall or glass. Summary of the Invention

[0004] In order to solve the deficiencies in the prior art, a suction cup device with stronger adsorption force is provided.

[0005] The utility model is implemented by adopting the following technical solutions: a suction cup device, including a suction cup base, a suction cup body located on one side of the suction cup base, the axial outer end surface of the suction cup body including a vacuum adsorption layer located at its center and a glue adsorption layer located circumferentially outside the vacuum adsorption layer; a pull rod extending toward the suction cup base is provided at the center of the axial inner end surface of the suction cup body, and a pulling device for realizing the movement of the pull rod in the axial direction is provided on the other side of the suction cup base, and the pulling device can pull the pull rod to form a negative pressure in the vacuum adsorption layer.

[0006] When in use, the user first presses the suction cup body on the glass or wall, and then operates the pulling device to move the pull rod in the direction away from the suction cup body, so that the vacuum adsorption layer achieves negative pressure, thereby completing the adsorption of the suction cup on the wall or glass.

[0007] The pulling device may be any existing device that can realize axial movement of the pull rod, such as a rotating device in a comparative document.

[0008] The materials of the glue adsorption layer and the vacuum adsorption layer are different. The glue adsorption layer is usually made of silicone material such as PU, while the vacuum adsorption layer is made of TPU.

[0009] The suction cup body of this solution includes a vacuum adsorption layer at the center and a glue adsorption layer located circumferentially outside the vacuum adsorption layer. The glue adsorption layer is located circumferentially outside the vacuum adsorption layer. The glue adsorption layer uses the viscosity of the silicone to make it closely contact the wall or glass surface. When the glue adsorption layer is in close contact with the wall or glass surface, the glue will deform to a certain extent under the action of the external atmospheric pressure, thereby forming a negative pressure area. The vacuum adsorption layer is then pulled by the pull rod to form a vacuum negative pressure, thereby achieving a secondary adsorption effect. At the same time, the glue adsorption layer is arranged around the circumferential outside of the vacuum adsorption layer, so that the circumferential airtightness of the vacuum adsorption layer can be better, ensuring that there will be no air leakage.

[0010] Preferably, the vacuum adsorption layer is circular, and the wall of the vacuum adsorption layer is gradually recessed toward the axial inner side of the suction cup body from the radial outer side to the radial inner side.

[0011] The vacuum adsorption layer is circular and its wall is concave toward the center of the suction cup body and axially inward, so that the negative pressure effect of the vacuum adsorption layer is better.

[0012] Preferably, the glue adsorption layer is annular, and the wall of the glue adsorption layer is protruding toward the axial outside of the suction cup body.

[0013] The wall of the glue adsorption layer is convexly arranged toward the axial outer side of the suction cup body, which can be deformed to a greater extent and achieve a better adsorption effect.

[0014] Preferably, the suction cup body includes a suction cup base that forms the entire suction cup body, the material of the suction cup base is the same as the material of the vacuum adsorption layer, the center of the suction cup base extends axially outward to form the vacuum adsorption layer, and the circumferential edge of the suction cup base is provided with a circle of annular convex edges extending axially outward, an annular groove is formed between the annular convex edge and the vacuum adsorption layer, and the glue adsorption layer is embedded in the annular groove.

[0015] The suction cup base is made of the same material as the vacuum adsorption layer, so that the center of the suction cup base extends axially outward to directly form the vacuum adsorption layer, and at the same time forms an annular groove with the annular convex edge, and the glue adsorption layer is embedded in the annular groove, which is more firm and has better sealing performance.

[0016] Preferably, an unlocking pull block extending radially outward is provided on the circumferential outer wall of the suction cup body.

[0017] The user can pull the unlocking pull block to allow air to enter the glue adsorption layer, thereby facilitating the unlocking of the suction cup's adsorption state.

[0018] Preferably, friction protrusions are provided on both side walls of the unlocking pull block.

[0019] The friction protrusion can increase the friction force, making it easier for the user to grasp the unlocking pull block.

[0020] Preferably, the unlocking pull block and the suction cup base are integrally formed.

[0021] The one-piece molding setting can ensure sealing while also making it easier for the suction cup base to deform when the unlocking pull block is pulled up, allowing air to enter.

[0022] Preferably, the axial inner end face of the suction cup body is provided with a plurality of positioning racks evenly spaced circumferentially, and the side of the suction cup base facing the suction cup body is provided with a plurality of positioning tooth grooves corresponding one to one with the positioning racks, and when the pull rod is pulled, the positioning racks contact and cooperate with the positioning tooth grooves.

[0023] The cooperation between the positioning rack and the positioning tooth groove has the advantages of positioning and preventing the suction cup from rotating.

[0024] Preferably, the lifting device includes a flip handle and an axially open mating groove arranged on the other side of the suction cup base, the flip handle is provided with a rotating block rotatably connected in the mating groove; the pull rod is passed through the mating groove and is rotatably connected to the rotating block; the rotation point of the pull rod and the rotating block rotationally connected deviates from the rotation point of the rotating block and the mating groove rotationally connected; when the flip handle rotates, the pull rod moves in the axial direction; the outer side of the pull rod is provided with a spring, and the spring is provided between the suction cup base and the suction cup body, and the spring applies a force to the suction cup body to move the suction cup body away from the suction cup base.

[0025] By flipping the handle, the user can flip it, causing the pull rod to move axially, pulling the center of the suction cup body back and forth, thereby achieving suction or release of the vacuum adsorption layer. The rotation point of the pull rod's rotational connection with the rotating block deviates from the rotation point of the rotating block's rotational connection with the mating groove, so that when the handle is flipped, the rotating block rotates. Since the rotation point of the pull rod's rotational connection with the rotating block deviates from the rotation point of the rotating block's rotational connection with the mating groove, the axial position of the pull rod changes after the rotating block rotates, thereby achieving axial movement of the pull rod. A spring also facilitates unlocking the suction cup.

[0026] A suction cup hook having the above-mentioned suction cup device, wherein a hook assembly is provided on the suction cup base.

[0027] The hook can be any existing hook that can be used to hang daily necessities such as washbasins, towels, bath balls, etc., and can be fixed to the suction cup base by screwing, welding, riveting, snapping, etc.

[0028] Compared with the prior art, the utility model has the advantage of stronger adsorption force. BRIEF DESCRIPTION OF THE DRAWINGS
