Description

  The present invention relates to the structure of a suction cup, and more particularly to the structure of a suction cup that has large irregularities and can be adsorbed on a rough surface.

  The suction cup is a structure having a function of adsorbing and fixing on a flat surface, and can be adsorbed quickly and easily on the surface to be adsorbed. Therefore, it is not necessary to perform a drilling operation that may cause damage to the object or a task of driving a nail in the fixing operation, and the materials can be bonded or fixed. Accordingly, the suction cups are widely used in, for example, bathrooms, kitchens, automobiles, and glass, and can be used as a means for suspending articles and a structure for fixing.

  However, the conventional suction cups may come off when the surface is rough after a long time or when the weight is hung after vacuum suction, and there is no ideal suction force and hanging load. The development of a suction cup having a strong adsorption force even on a rough surface has been eagerly desired.

  Therefore, the subject of this invention is providing the structure of the suction cup which can be made to adsorb | suck to a rough surface and can maintain an adsorption state over a long period of time.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited by these.

  Please refer to FIG. 1 and FIG. As shown in FIGS. 1 and 2, the structure of the suction cup according to an embodiment of the present invention includes a suction cup 10, a spring 20, a fixed seat 30, a control handle 40, and a ring 50. The suction cup 10 includes a first structure layer 11 and a second structure layer 12. The first structural layer 11 is flexible and elastic, and is used to directly contact the object to be adsorbed. The second structural layer 12 is hard and deforms when the fixed seat 30 is pressed, and generates a vacuum adsorption force. The suction cup 10 has a support 13 extending from the central portion of the second structural layer 12. A pivot attachment hole 14 is provided on the support 13. The fixed seat 30 is a lid, has a through hole 31 provided in the center portion, and a hollow columnar cover 32 is provided on the top surface so as to correspond to the through hole 31. The cover 32 has groove portions 33 opened in parallel to the axial direction on both sides, an engagement portion 34 is provided at an end portion, and a hook portion 35 is extended outward. The control handle 40 includes a pivoting portion 41 provided at one end portion and a swinging portion 42 provided at the other end portion. The pivoting portion 41 is provided with an eccentric projection and includes a pivoting hole 44 and a notch 43. The ring 50 includes a peripheral portion 51 having an arbitrary shape that is continuously provided, and through holes 52 provided at both ends.

  Please refer to FIG. 1 and FIG. As shown in FIGS. 1 and 3, the spring 20 is fitted on the support 13 of the suction cup 10. The suction cup 10 is installed in the cover 32 by penetrating the support 13 through the through hole 31 of the fixed seat 30, and covers the suction cup 10 with the fixed seat 30. The control handle 40 is fitted to the outside of the cover 32 by a notch 43. When the shaft rods are inserted through the corresponding pivot mounting holes 14 and 44 and the groove 33, the control handle 40 and the support 13 of the suction cup 10 are pivotally mounted on the fixed seat 30, respectively. 34, the ring 50 is engaged by the through hole 52.

  When the suction cup according to the present invention is actually used, the suction cup 10 is brought into contact with a smooth flat surface using the first structure layer 11 and then controlled by the swinging portion 42. When the edge of the eccentric pivot 41 is brought into contact with the fixed seat 30 and the suction cup 10 is pulled outward by the control handle 40, a vacuum suction force is generated therein. Thus, when the outer peripheral edge part of the suction cup 10 is pushed down by the fixed seat 30, the suction cup 10 can be reliably adsorbed to a smooth flat surface. When the surface of the object to be adsorbed is rough, the first structural layer 11 is deformed to eliminate the gap between the rough surface and prevent air from entering the suction cup 10 from the outside as shown in FIG. Thus, a vacuum state can be formed and the suction state of the suction cup 10 can be maintained. Therefore, the suction cup 10 of this embodiment can be used for various articles.

  Further, the second structural layer 12 and the first structural layer 11 are laminated with each other (shown in FIGS. 1 to 4) and fitted (shown in FIG. 5), and are arranged on the upper and lower portions of the suction cup 10, respectively. Alternatively, the first structure layer 11 and the second structure layer 12 may be concentrically coupled from the outside to the inside (shown in FIG. 6). Further, when the suction cup 10 is actually used, the first structure layer 11 is used to directly contact the object to be adsorbed.

  Please refer to FIG. As shown in FIG. 7, the suction cup structure according to the embodiment of the present invention can attach the suction cup 10 to the through hole 52 of the ring 50 through the key 60 without destroying the object to be sucked. When removing, the entire suction device together with the ring 50 and the key 60 can be quickly removed simply by swinging the control handle 40. Therefore, the key 60 can be carried to another place, or the key 60 can be attracted again at another place, which is convenient for use. As can be seen from the above description, the suction cup structure of the present embodiment does not require nailing or sticking the key holder, so that time and labor can be saved.

  Further, the suction device of the present embodiment allows two or more of them to be sucked at intervals, engages a chain in which an article is suspended between two rings 50 facing each other, or hooks 35 of the fixed seat 30 itself. Can be used in various manners.

  As can be seen from the above, the suction structure of the present invention has a suction cup 10 from the outside by eliminating the gap between the rough surface by deforming the first structural layer 11 when the surface of the object to be adsorbed is rough. A vacuum state is formed by preventing air from entering the interior of the chamber. Moreover, since the suction cup 10 of this embodiment can hold | maintain the adsorption | suction state of the suction cup 10 with the 2nd structure layer 12, it can utilize for various articles | goods.

  The preferred embodiments of the present invention have been disclosed as described above so that those skilled in the art can understand them, but these do not limit the present invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the utility model registration claim of the present invention should be broadly interpreted including such changes and modifications.
