Detailed Description
The above objects, features and other advantages of the present invention will become more apparent by describing in detail preferred embodiments of the present invention with reference to the attached drawings. A suction plate according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is an exploded perspective view of a suction plate according to a first embodiment of the present invention, fig. 2 is a side sectional view of the suction plate according to the first embodiment of the present invention, fig. 3 is a side sectional view of a state where a drawing unit according to another embodiment is attached to the suction plate according to the first embodiment of the present invention, and fig. 4 is a partial side sectional view of the suction plate according to a second embodiment of the present invention.
Referring to fig. 1 and 2, the suction plate 100 according to the first embodiment of the present invention includes a suction part 110, a main body part 120, an elastic part 130, a pressing part 140, and a drawing part 150.
As shown in fig. 1 and 2, the suction portion 110 is formed of a soft material such as rubber, and a suction surface 112 is formed on a bottom surface formed concavely. Thus, if the suction surface 112 is pressed against the mounting surface, a vacuum is formed between the suction surface and the mounting surface.
In the suction part 110, a hard extension shaft 116 serving as a screw shaft is fixed to the center of the convex upper surface.
The body 120 is made of a hard material such as a synthetic resin material, and has a through hole 122 formed in a center portion thereof in a longitudinal direction so as to allow the extension shaft 116 to pass therethrough, and a coupling ring 124 provided on an outer circumferential surface side so as to allow the shelf or the like to be fixed.
In this case, the coupling ring 124 is shown as being provided on the body 120, but is not limited thereto, and may be independently attached to an end of the ring and provided on the body 120 in a state of being naturally rotated.
Further, the main body portion 120 is provided with a close force increasing portion 126 in a ring shape along the bottom surface edge.
On the other hand, the adhesion force increasing section 126 is formed of a double-sided tape, a rubber sheet, or the like so as to be firmly fixed to the attachment surface independently of the suction surface 112 of the suction section 110.
The adhesion force increasing part 126 is disposed in such a manner that the inner edge of the bottom surface is placed along the edge of the upper surface of the suction part 110 and partially overlapped, so that the suction part 110 can be adhered to the mounting surface without a gap even if the mounting surface is uneven and rough.
In this case, the increased adhesion force section 126 preferably overlaps 1/3 or 1/2 of the entire width of the suction section 110.
On the other hand, although not shown, the adhesion force increasing part 126 may have a groove formed along the inner edge of the bottom surface, and may be flat with the suction part 110 if the edge of the suction part 110 is located in the groove.
As described above, since the force transmitted by the main body 120 pressing the suction unit 110 is transmitted to the adhesion force increasing unit 126 and the continuous force is applied to the suction surface 112 to press the same, the vacuum state can be maintained for a long period of time.
Further, although not shown in the drawings, the adhesion force increasing section 126 of the main body section 120 is formed with a ridge extending inward of the edge so as not to adhere thereto, and the extending section presses the upper surface edge of the suction section 110, so that the edge of the suction section 110 firmly covers the pressing attachment surface.
The periphery of the through hole 122 of the body 120 is recessed to support the end of the elastic part 130.
The elastic portion 130 is a compression spring for providing an elastic force, and is provided to surround an extension shaft 116 positioned between facing surfaces of the main body portion 120 and the drawing portion 150 so as to press the main body portion 120 toward the suction portion 110.
As described above, the elastic part 130 provides a double pressurizing force together with the drawing part 150 so that the main body part 120 can pressurize the suction part 110, thereby improving the adhesion force of the adhesion surface.
The pressing part 140 is formed with a communication hole 142 to be inserted into the extension shaft 116, and is formed with a groove at a lower portion to support an upper end of the elastic part 130.
The drawing unit 150 is screwed to an end of the extension shaft 116 passing through the communication hole 142 of the pressurization unit 140, and functions to draw the extension shaft 116 when rotated so that the suction surface 112 of the suction unit 110 is sucked to a fixed surface.
The drawing portion 150 has a groove formed radially on the surface thereof so as to be easily held by a hand.
Referring to fig. 3, the drawing part 150' of another embodiment may employ a lever type. In this case, when the pulling part 150 'is of a lever type, the extension shaft 116' is smoothly formed without a screw, and is rotatably disposed in a groove formed at the upper end of the extension shaft 116 via a hinge. At this time, the drawing part 150' is composed of a pressing surface 152' and a protrusion 154 '.
Further, the hinge H is eccentrically coupled to the pulling portion 150 'with respect to the pressing portion 152', and if the protrusion 154 'is erected upward, the pressing portion 152' is separated from the upper surface of the pressing portion 140, but if the protrusion 154 'is rotated to the side, the eccentric pressing portion 152' presses the upper surface of the pressing portion 140 and simultaneously presses the elastic portion 130 to the pressing portion 140.
Therefore, the elastic part 130 presses the body part 120, and thus the body part is more firmly attached due to continuous pressing while pressing the suction part 110.
Therefore, if the extension shaft 116 'is pulled by rotating the pulling part 150', a vacuum is formed in the suction part 110 by the elasticity of the elastic part 130, and thus the length is increased. Also, when the adsorption part 110 falls, the edge falls with the entrance of air.
A process of fixing the suction plate 100 of the first embodiment of the present invention configured as described above to a mounting surface will be described below.
First, after the release paper is removed from the adhesion force increasing section 126 attached along the bottom surface edge of the main body 120, the main body 120 is first fixed to the mounting surface by the adhesive force.
Then, when the pulling part 150 is pressed toward the mounting surface side in a state where the pulling part 150 is loosened in the counterclockwise direction, the suction surface 112 of the suction part 110 is sucked to the mounting surface.
Then, when the pulling part 150 is rotated in the clockwise direction, the degree to which the pulling part 150 is screwed to the extension shaft 116 increases, and the pressing part 140 is pressed.
Then, the extension shaft 116 of the suction unit 110 is pulled by the pulling unit 150 while the elastic unit 130 pressurizes the body unit 120, and thus a vacuum is formed between the attachment surface and the suction surface 112 of the suction unit 110.
As described above, the suction portion 110 is pressurized by the extension shaft 116, and the main body portion 120 is pressurized by the elastic portion 130, so that the suction portion is strongly sucked and fixed to the mounting surface in a dual manner.
Referring to fig. 4, the suction plate according to the second embodiment of the present invention includes a suction part, a main body part 220, an elastic part 230, a pressing part 240, and a drawing part 250, and a hanging part 218 is additionally formed on an extension shaft 216 of the suction part, and only the shape of the pressing part 240 is changed, so that only this part will be described.
On the outer peripheral surfaces of the extended shaft 216, which is a screw shaft, facing each other, grooves are formed in the height direction, and the hook portions 218 are provided in the facing grooves in a symmetrical state, and the lateral elastic portions S are provided therebetween.
At this time, the hook portion 218 is partially inserted into both ends of a mounting hole G formed in the extension shaft 216 to penetrate in the horizontal direction, and a slant surface 218a having a narrow top and wide bottom is formed to be exposed to the outside of the extension shaft 216.
The engaging portion 218 is provided to protrude from the outer circumferential surface of the extension shaft 216 by the elastic force of the lateral elastic portion S, so that the lower horizontal surface can be engaged around the lower communication hole 242b of the pressurizing portion 240.
The pressing portion 240 has upper and lower communication holes 242a and 242b formed therethrough so as to penetrate the extension shaft 216, and a space is formed therebetween in which the hanging portion 218 is located.
Further, the pressurizing portion 240 is symmetrically formed with through holes 244 in the outer circumferential surface between the upper and lower communication holes 242a, 242b in the lateral direction, and when the pressurizing portion 240 is to be separated, the both side hooking portions 218 can be pressurized through the through holes 244.
Further, the pressing portion 240 is located above the engaging portion 218 before the pulling portion 250 is completely fixed, but if the pulling portion 250 is rotated clockwise to completely fix the pulling portion 250, the pressing portion 240 gradually descends, the lower communication hole 242b gradually presses the inclined surface 218a of the engaging portion 218 in the symmetrical direction (inward), the lower communication hole 242b passes the inclined surface 218a of the engaging portion 218, and the engaging portion 218 is located between the upper and lower communication holes 242a and 242 b. After the hooking portion 218 is positioned between the upper and lower communication holes 242a and 242b, it is projected outward by the restoring force of the lateral elastic portion S, and a horizontal surface adjacent to the lower end of the inclined surface 218a is interfered, so that the pressing portion 240 cannot move in the direction of the drawing portion 250.
As described above, since the pressing portion 240 in a state of pressing the elastic portion 230 cannot move due to the hooking portion 218, the position of the pressing portion 240 does not change even if the pulling portion 250 is slightly loosened from the extension shaft 216.
On the other hand, a plurality of pressing portions 240 may be provided in the height direction on the extension shaft 216, and the uppermost pressing portion 240 presses the both inclined surfaces 218a via the screw hole 252 of the pulling portion 250.
While the embodiments of the present invention have been described with reference to the drawings, it will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments described above are therefore to be considered in all respects as illustrative and not restrictive.
