The present invention, unlike glass or tiles, etc., the surface is not smooth, and is easily removable on a slightly uneven or scratched surface, and relates to a vacuum adsorption plate of the vacuum adsorption mechanism to maintain the adsorption power to the maximum.

In general, the adsorption plate has been used to hang or attach a towel rack or a tissue hanger to a smooth surface such as glass or tile, and the structure of the adsorption plate is gently inclined downward toward the rim so that the center portion is convex upward. It is disc-shaped and has a structure in which protrusions are formed at the center of its upper surface.

The adsorption plate having the above structure can be used simply by pressing the protrusions to bring the bottom of the adsorption plate into close contact with the surface to be adhered, that is, by the property that the adsorption plate closely adhered to the surface to be adhered returns to its original state. The central part of the adsorption plate is spaced apart from the surface to be adhered to create a state close to the vacuum. At this time, the pressure between the surface to be adhered and the adsorption plate becomes lower than the atmospheric pressure outside the adsorption plate. Strong adhesion is maintained between the parts.

However, if the pressure between the surface to be adhered and the adsorption plate is not significantly different from the atmospheric pressure, the adsorption force is not only low, but as the adhesion time increases, air is introduced through the minute gap between the surface of the surface to be adhered and the adsorption plate. In this case, the air supply field loses the adsorption force between the surface to be adhered and the adsorption plate, and thus, a problem arises such that a valuable adherent fixed to the surface to be adhered by the adsorption plate falls and breaks or touches the floor surface. .

Accordingly, there is a search for an improved method of easily adsorbing the adsorption plate on the surface to be adhered and generating a strong adsorption force. As an example, the "multipurpose vacuum" disclosed in the Korean Utility Model No. 420964 is disclosed. Adsorption mechanism "is as follows.

1 is a view showing the main configuration of a general vacuum adsorption mechanism, Figure 2 is a view showing a state that the adsorption plate of the vacuum adsorption mechanism is adsorbed on the surface to be attached.

Referring to these drawings, the conventional multi-purpose vacuum adsorption mechanism is in close contact with the surface to be attached to generate a pressing force, and a plurality of fixing protrusions 11 formed along the upper periphery and protruded from the center of the upper surface and a ring-shaped end on the outer peripheral surface. A vacuum suction plate (10) having a locking projection (12) having a jaw portion (13) formed thereon; An elastic member 20 having one end caught by the elastic member engaging protrusion 14 protruding from the upper surface of the vacuum suction plate 10; A fixing groove 31 into which the fixing protrusion 11 is inserted is provided at an inner circumferential surface of the bottom to support a ring portion of the vacuum suction plate 10, and extends upwardly of the base ring portion 32. A lower support 30 formed at equal intervals on the upper circumferential portion of the first side wall portion 33 of the tubular body and having guide ribs 34 formed thereon; The guide protrusion 42 protrudes from the upper end of the inner circumferential surface of the second side wall portion 41 surrounding the outer circumferential surface of the first side wall portion 33, and the adsorption block is located at the center of the bottom surface of the plate-shaped upper base 43 that blocks the upper end of the second side wall portion. Adsorption plate operating member 40 with projecting base 44 protruding is sequentially combined and combined.

Therefore, in the conventional multipurpose vacuum adsorption mechanism having the above structure, the lifting protrusion 12 of the center portion is forcibly lifted, particularly in the state in which the edge portion of the vacuum suction plate 10 is supported to be in close contact with the adhered surface. It is a structure in which the suction force is increased by making the vacuum surface between the attaching surface and the bottom of the vacuum suction plate 10 almost vacuum.

At this time, the suction plate operating member 40 is guided by a plurality of guide ribs 34 formed on the lower support 30 due to the rotational operation is spaced apart from the lower support 30, that is, the guide while rotating Guided along the high point from the low point of the inclined surface of the rib 34 is relatively spaced upward relative to the lower support (30).

The conventional adsorption mechanism having the structure as described above, the lower support (30) by closely holding the edge of the vacuum suction plate 10 to prevent the air from entering between the surface to be attached and the vacuum suction plate 10, The space between the bottom of the vacuum adsorption plate 10 is made almost in a vacuum state, and the adsorption plate operating member 40 maintains a state spaced upwardly while rotating relative to the lower support 30, thereby providing a central portion of the vacuum adsorption plate 10. Stop the lifted to the top to continue the adsorbed state.

Therefore, the adsorption force is excellent by maintaining the adsorbed state, and in the case where the desorption is desired, the adsorption plate operating member 40 is rotated in the opposite direction to return the center portion of the vacuum adsorption plate 10 to the bottom surface. The vacuum suction plate 10 has the advantage that can be easily separated by releasing the vacuum between the bottom.

Further, in the adsorption mechanism according to the prior art, the adsorption force is not lost when the surface to be contacted in direct contact with the edge of the vacuum adsorption plate 10 supported by the lower support 30 is smooth, such as glass or tile surfaces. No, it will stay for a long time.

On the other hand, if the upper surface of the surface to be attached which forms the contact surface directly below the edge of the vacuum adsorption plate 3 is not smooth or smooth, unlike the glass or tile surface or the like, if the irregularities are formed in a part of the region, the irregularities or smoothness Outside air flows through the gap between the surface and the bottom surface of the vacuum adsorption plate 3, so that the adsorption force is lost, and after the adsorption, there is a problem such that the adherend is dropped and broken or dirty.

The present invention was created in view of the above problems, and even if the upper surface of the surface to be contacted with the vacuum adsorption plate is not smooth or smooth unlike glass or tile surface, it is easy to adsorb even when irregularities or scratches are formed in a part of the area. It is an object of the present invention to provide a vacuum adsorption plate of a vacuum adsorption mechanism in which adsorption force after adsorption is maintained without loss for a long time, so that the adherend is firmly supported and fixed.

The above object of the present invention is achieved by further comprising a material layer of high viscosity geltape on the bottom surface adjacent to the edge of the vacuum suction plate supported by the lower support.

Vacuum adsorption plate of the vacuum adsorption mechanism according to the present invention, the disk-like, the vacuum adsorption plate protruding the adsorption engaging projection in the center of the upper surface; A base ring part in close contact with an upper edge of the upper surface of the vacuum suction plate; A first side wall portion extending from the base ring portion; A lower support comprising an operating rib extending at equal intervals from each other along an upper periphery of the first side wall, the second support comprising: a second side wall portion external to the outer circumferential surface of the side wall of the lower support; A rib guide protrusion formed on an inner circumferential surface of the second side wall portion and guided on the working rib, respectively; An upper base as a horizontal plane formed integrally with an upper end of the second side wall portion; In the vacuum suction mechanism consisting of a suction plate operating member made of a suction locking projection support extending from the bottom of the central portion of the upper base toward the bottom, the upper end of the suction locking projection is fixed to the lower portion, the bottom surface of the vacuum suction plate, The adhesive ring forming a concentric circle with the vacuum adsorption plate on the bar is characterized in that additionally, looking at this in detail as follows.

The vacuum suction plate of the vacuum suction device of the present invention has the convex bottom part and the adhered surface of the vacuum suction plate, while the shape of the vacuum suction plate is convex upward by the locking projection of the central part being lifted upward in close contact with the surface to be attached. A vacuum is formed therebetween, and a large air pressure difference is generated between the internal space in which the vacuum is formed and the atmospheric pressure outside, thereby compressing the bottom surface of the edge of the vacuum suction plate.

In addition, the vacuum adsorption plate of the vacuum adsorption mechanism, in particular, the bottom surface is additionally coupled to the adhesion ring concentric with the vacuum adsorption plate on a plan view, in general, since the vacuum adsorption plate forms a disk to effectively create and maintain a vacuum, the It is preferable that the adhesive ring also takes a ring shape.

That is, the adhesive ring is additionally coupled in a state spaced apart from the edge of the bottom of the vacuum suction plate on the disc of the vacuum suction mechanism by a predetermined interval, as shown in Figure 1 to Figure 2 the base portion of the lower support base ring In the case of being in close contact with the bottom of the part, it is preferable that the adhesive ring is additionally coupled to the bottom directly under the contact surface of the vacuum adsorption plate supported in close contact with the base ring portion of the lower support.

In addition, in order for the adhesive ring to be additionally firmly coupled to the bottom of the vacuum suction plate, it is preferable that an indentation groove is formed at the bottom of the vacuum suction plate to which the adhesive ring is coupled to insert the upper portion of the outer circumferential surface of the adhesive ring. The concave groove has a so-called under-cut (under-cut. General term commonly used in mold making) shape that becomes wider toward the upper side, and thus the adhesive ring coupled thereto is more firmly coupled.

In particular, the injection mold forming the inner circumferential surface of the recessed groove is subjected to corrosion (a common technical term used in mold making, which is a mold manufacturing technique for forming fine irregularities on the surface of the injection molded product). By adhering the adhesive ring to the surface of the shape, the adhesive ring is more firmly coupled to the recess groove of the vacuum suction plate.

In addition, the adhesive ring is preferably a gel-type polyurethane, in order to exhibit excellent adhesive force, it is preferable to apply a polyurethane of a gel (gel) leaf having a viscosity of 100 ~ 300pcs, vacuum adsorption In the injection molding of the vacuum suction plate of the mechanism, while the soft vacuum suction plate is molded, the hard locking projections of the center part are double-injected. Similarly, the adhesive ring is also double-injected to shorten the manufacturing time due to the injection molding.
