Description

Vacuum fixture { Vacuum fixture }

The present invention relates to a vacuum suction port, and more specifically, by pulling the center of a suction plate attached to an adherend such as glass, mirror, tile, furniture, etc. While increasing the adsorption force, it is possible to prevent the platen that presses the suction plate from sliding or rotating on the upper surface of the suction plate. It relates to a vacuum adsorption port that can be stably maintained for a long time.

In general, vacuum adsorbents are used for attaching products to the surface (adhering surface) of an adherend without damaging the surface of glass, mirror, tile, furniture, etc. It is a device used to install lightweight household items such as toiletries storage boxes.

According to the adsorption method, there are a method of vacuum compression by simple pressure by hand, a method of vacuum compression by pulling a lever, and a method of vacuum compression through tightening screws. As prior art related thereto, Patent Publication No. 10-2009-0096379 (Reference 1), Patent Publication No. 10-2015-0144948 (Reference 2), etc. have been proposed.

Reference 1 relates to a suction plate of a simple pressurization method, and a general structure of a suction plate formed of a soft material and a convex curved surface on one side is proposed. This structure is used by simply pressing the center of the suction plate with a finger, and there is no separate configuration for pressing the surface of the suction plate. Since it is not provided, as it relies on the self-restoring power of the sucker, the adsorption force applied to the adherend surface such as glass, mirror, or tile is weak and falls off easily, making it unsuitable for attaching towel racks, soap stands, and toiletries storage boxes, mainly for fixing light and unbreakable objects. Therefore, its use is extremely limited.

Next, in the prior art of Reference 2, the structure of the suction port of the lever method and the screw tightening method is proposed. The conventional vacuum suction port of the lever method of Reference 2 includes a suction plate formed in a hemispherical shape to have adhesion to the adherend surface, a support cap coupled to the upper portion of the suction plate, a post provided through the support cap, and an upper end of the post It consists of an actuating lever that is pivotally coupled, and when the actuating lever is turned while the adhering plate is in close contact with the adherend, the adsorption member is lifted by the post connected to the actuating lever, and the vacuum state between the adhering surface and the adhering plate becomes attached to the adherend. Able to know.

And the conventional vacuum suction port of the screw tightening method of Reference 2 is a cap-shaped case in which the through-holes are formed in the center up and down, and the post aligned with the through-hole and provided with a thread, and is made of a soft material provided on the lower side of the case. a suction plate, a tightening nut screwed to the tip of the post, and a pressing ring fitted to the periphery of the bottom surface of the case so that a part of the bottom overlaps the upper surface of the periphery of the suction plate, wherein the pressing ring is harder than the suction plate It is made of a soft material with a low In such a vacuum suction port, after pressing on the adherend surface, when the tightening nut is tightened, the central portion of the suction plate is lifted upward, and when the central portion of the suction plate is lifted, vacuum pressure is generated in the sealed space formed between the adherend surface and the suction plate. It can be seen that the vacuum adsorption port is attached.

However, in the suction port of the lever method and screw tightening method proposed in Reference 2, the post on which the disk-shaped support part is formed in the lower part is fixed in the insert method to prevent separation from the suction plate during injection molding of the suction plate. When pulled, the support part of the post lifts the center of the suction plate, so the vacuum area formed by separating from the adherend surface is formed wider than the support area of the post, causing the distance from the edge of the vacuum area to the edge of the suction plate to become shorter. It is disadvantageous in maintaining the adsorption power for a long time due to the high risk of influx of

In addition, in the suction port of Reference 2, when the support cap or the tightening nut is pulled in one direction, the vacuum space is biased toward the other side of the suction plate, and the distance between the other side of the vacuum area and the edge of the other side of the suction plate is abruptly shortened. It also has the disadvantage of being easily separated from the adherend due to the rapid influx of the material.

In addition, in the suction port of Reference 2, support jaws are continuously formed on the circumference of the same radius along the lower edge of the case to press the edge of the suction plate. When the support cap or tightening nut is pulled in one direction due to the characteristics of the suction plate, one side of the suction plate is compressed and thickened and the other side is pulled and thinned. There is also a problem in that the air is more easily introduced into the vacuum space and the adsorbent is more easily separated from the adherend.

Reference 1: Korean Patent Publication No. 10-2009-0096379 Reference 2: Korean Patent Publication No. 10-2015-0144948

In order to solve the problems of the conventional vacuum suction port, the present invention increases the suction power by minimizing the vacuum area generated when the central part of the suction plate is pulled upward, and at the same time presses the upper surface of the suction plate to the lower surface of the pressure plate that presses the suction plate. By forming a plurality of independent pressure protrusions, the pressure plate can be prevented from sliding or rotating on the upper surface of the suction plate, and even if the pressure plate is pulled in one direction, the vacuum area is enlarged and biased in the other direction of the suction plate from the edge of the vacuum area to the edge of the suction plate An object of the present invention is to provide a vacuum adsorption port capable of preventing the rapid inflow of external air into the vacuum space by minimizing the shortening of the distance.

In addition, the present invention prevents the initial pressure portion of the suction plate from being separated even if the pressure plate is pulled to one side, and after a predetermined time has elapsed after attaching the suction plate, the pressure plate presses the suction plate more stably, so that the suction plate is in a stable adsorption state on the adherend surface. An object of the present invention is to provide a vacuum adsorption port that can be maintained for a long time.

The present invention for solving such technical problems;

a suction plate in which the head protrudes above the center of the suction body whose lower surface is in close contact with the adherend surface of the adherend; A pressure plate in which a plurality of independent pressure protrusions are formed to press the upper surface of the suction plate, but protrude downward while maintaining a predetermined interval at the lower portion of the pressure body in which the through-portion through which the head is penetrated is formed in the center; and a tightening member for pressing the pressure plate to the suction plate while pulling the head protruding upward through the through portion of the pressure plate.

At this time, the independent pressing protrusion is protruded downward from the lower portion of the pressing body to press the upper surface of the absorption body of the suction plate, characterized in that made of any one of the shape of a cylinder, a prism, and a hemispherical shape.

And the independent pressure protrusion is protruded downward from the lower portion of the pressure body and is characterized in that it is formed in a needle shape with a pointed end so as to dig into the upper surface of the suction body of the suction plate.

In addition, a male thread is formed on the outer peripheral surface of the head of the suction plate; The tightening member has a head inlet portion formed on an inner circumferential surface of which a head portion of the suction plate is guided and a female thread screwed to a male screw thread of the head portion is formed; The pressure plate is formed with a support portion to which the lower end of the tightening member is pressed along the edge of the through portion, and a storage space is formed in the lower portion of the support portion through which the periphery of the center of the adsorption body flows when the head is pulled upward. do.

In addition, a support groove is formed in the upper center of the head of the suction plate, and a central support protrusion inserted into the support groove formed in the center of the upper end of the head of the suction plate in the head inlet of the tightening member protrudes downward. .

And it is characterized in that the suction plate and the tightening member are screwed in a state in which lubricating oil is applied to the male thread formed in the head of the suction plate or the female thread formed in the head inlet of the tightening member.

According to the present invention, when the head of the suction plate is pulled upward to form a vacuum in the lower center of the suction plate, the vacuum area in the lower center of the suction plate is minimized to increase the suction power and at the same time a plurality of formed on the lower surface of the pressure plate that presses the suction plate The end of the independent pressure protrusion evenly presses the upper surface of the suction plate to prevent the pressure plate from sliding or rotating on the upper surface of the suction plate. By minimizing the shortening of the distance to the edge of the suction plate, it is possible to keep the suction power of the suction plate strong for a long time by blocking the inflow of external air into the lower center of the suction plate.

And according to the present invention, as a plurality of independent pressing projections are evenly formed on the lower surface of the pressing plate, even if the suction plate is closely adhered to the uneven tile having an uneven surface and a curved surface, each independent pressing projection pressurizes the upper surface of the suction plate. Accordingly, there is an advantage that the suction plate adheres well to the curved adherend surface, and thus the function of the vacuum suction port can be faithfully performed.

In addition, according to the present invention, when the independent pressure protrusion of the pressure plate is formed in the shape of a needle, it is possible not only to completely prevent the initial pressure portion of the suction plate from being separated from the tip of the needle, but also to continuously press the suction plate to the adherend surface of the adherend. As the end of the independent pressure protrusion slowly penetrates and supports the surface of the suction plate, the pressure plate presses the suction plate more stably, which also has the effect of increasing the suction power of the suction plate to the adherend surface.

Hereinafter, a vacuum adsorption port according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 4 are views for explaining a vacuum adsorption port according to an embodiment of the present invention.

According to this, the vacuum suction port 1 of the present invention is adsorbed on the adherend surface 20 of the adherend 2 such as glass, mirror, tile, furniture, etc., the suction plate 100 with the head 120 protruding upward from the center. And, the pressure plate 200, which presses the upper surface of the suction plate 100, and the through portion 220 through which the head 120 penetrates is formed in the center, and the through portion 220 of the pressure plate 200 passes through and a tightening member 300 for pressing the pressure plate 200 to the suction plate 100 while pulling the head 120 protruding upward from the sea.

Hereinafter, each configuration of the present invention will be described in detail.

The suction plate 100 is made of a soft material, and the suction body 110, the lower surface of which is in close contact with the adherend surface 20 of the adherend 2 such as glass, mirror, tile, furniture, etc., and the suction body 110 It consists of a head part 120 provided on the upper center.

At this time, the suction plate 100 is compared to the method in which the head 120 is integrally made of the same soft material as the absorption body 110, and the head 120 is inserted and injected when the absorption body 110 is molded. ) can greatly reduce the manufacturing cost and the manufacturing process is also simple. The suction plate 100 may be injection molded with various soft materials such as urethane, PVC, rubber, etc., and various materials with excellent adhesion are also available. .

And the absorption body 110 is made of a disk shape and can be used with a uniform thickness as a whole, but a shape that becomes thinner as it goes from the center to the edge as a whole may be used. Changes are also possible, and it is natural that all of these degrees of modification fall within the scope of the present invention. In this case, when the suction body 110 is formed in a shape that decreases in thickness from the center to the edge as a whole, the lower surface of the pressure plate 200 also wraps around the top surface of the absorption body 110 to form a gently downward slope so that it can be in close contact. can

In addition, the head 120 vertically extends and protrudes above the center of the adsorption body 110 . The head 120 is preferably made in the form of a cylinder, but may be formed in the form of a square pillar, a hexagonal pillar, an octagonal pillar, etc. In addition, design changes within an equivalent range also fall within the scope of the present invention. Of course.

And the head 120 is pulled upward by the tightening member 300. For this purpose, a male thread 122 is formed on the outer circumferential surface of the head 120, and is screwed with the tightening member 300. do. Of course, the tightening member 300 may adopt a structure that lifts the head 120 upward by the principle of a lever in addition to the screw-coupled structure, and thus the present invention lifts the head 120 upward. If it is a structure that can press the pressure plate 200 to the suction plate 100 while raising it, various methods other than the screw coupling method and the lever method can be selectively employed, and such design changes all fall within the scope of the present invention. is natural

The fastening member 300 and the suction plate 100 may have a simple screw-coupled structure, but a support groove 124 is formed in the center of the upper end of the head 120 so that the head is screwed together with the fastening member 300 . It is preferable that the 120 is more stably and firmly screwed to the fastening member 300 while minimizing the deviation from the screwing portion or the distortion of the shape. To this end, the fastening member 300 is provided with a central support protrusion 320 inserted into the support groove 124 to support the head 120 . This tightening member 300 will be described in more detail later.

And the rim of the adsorption body 110 is horizontally formed to extend the handle 130 for separation. Therefore, when the separation handle 130 is lifted upward, external air is rapidly introduced into the vacuum space V, so that the suction plate 100 can be easily separated from the adherend surface 20 .

On the other hand, the pressure plate 200 is made of synthetic resin or a metal material to press the upper surface of the absorption body 110 of the suction plate 100 in the direction of the adherend surface 20 such as glass or tile, and penetrates vertically through the center. The pressure body 210 in the shape of a disk having a penetrating portion 220 through which the head 120 of the suction plate 100 passes is formed, and the pressure body 210 protrudes downward while maintaining a predetermined interval in the lower portion of the pressure body 210 to the suction plate. The adsorption body 110 of (100) consists of a plurality of independent pressure projections 230 to evenly press the upper surface.

At this time, the pressure body 210 is made of a disk shape and it is preferable to use a uniform thickness as a whole. It is of course within the scope of the

And the penetrating portion 220 formed to penetrate vertically in the center of the pressure body 210 is the suction body 110 when the head 120 of the suction plate 100 is pulled upwards of the through portion 220 . It is preferable that the periphery of the center is uniformly and stably pulled upward to prevent damage such as tearing.

In addition, a plurality of independent pressure protrusions 230 that protrude downward at a predetermined interval in the lower portion of the pressure body 210 and press the upper surface of the absorption body 110 of the suction plate 100 are the absorption body of the suction plate 100 . (110) The upper surface is evenly pressurized. These independent pressing protrusions 230 are uniformly formed on the lower surface of the pressing body 210, and in this case, they may be provided to protrude downward while maintaining a predetermined interval on a concentric circle, or may be formed entirely on the lower surface. Of course, it is obvious that the arrangement of the plurality of independent pressing protrusions 230 can be changed in various designs and all fall within the scope of the present invention.

At this time, the independent pressing protrusion 230 is formed in a column shape such as a cylinder, a prism, and the like so that the lower end can press the upper surface of the adsorption body 110, and a hemispherical convex protrusion is formed at the lower end of the column, or the adsorption body is formed in a hemispherical shape. (110) It is also possible to press the upper surface. In addition, the independent pressing protrusion 230 may be formed in various needle shapes such as a cone, a triangular pyramid, a quadrangular pyramid, etc. so that the independent pressure protrusion 230 may have a needle shape with a sharp tip so that it can be dug while pressing the upper surface of the absorption body 110 .

Such an independent pressing protrusion 230 may be made of the same material as the pressing body 210 or may be made of a different material. For example, when the pressure plate 200 is injection-molded with a synthetic resin, the independent pressure protrusion 230 is integrally formed on the lower surface of the pressure body 210, or a metal needle is applied to the pressure body 210 during injection molding. It is also possible to form the independent pressing protrusion 230 by inserting the , and it is natural that this degree of design change also falls within the scope of the present invention.

According to this structure, the end of the independent pressure protrusion 230 gradually presses the upper surface of the suction plate 100 over time while the pressure plate 200 is pressed against the suction plate 100 and holds the pressure position more firmly. Rather, the adsorption plate 100 is more closely adhered to the adherend surface 20 to maintain a stable adsorption state for a long time.

In addition, even if the pressure plate 200 for pressing the suction plate 100 is pulled to one side, the vacuum space (V) is not biased on the other side of the suction plate 100 so that the lower center of the suction plate 100 is lifted. It is also possible to prevent abruptly shortening of the distance between the area S and the other edge of the suction plate 100 , thereby preventing the rapid inflow of external air into the vacuum space V.

And when a plurality of independent pressing projections 230 are evenly formed on the entire lower surface of the pressing body 210, the independent pressing projections 230 are formed on a curved surface where the adherend surface 20 is uneven, such as an uneven tile, etc. 100) There is an advantage in that the suction plate 100 adheres well to the adherend surface 20 by pressing the upper surface.

On the other hand, when the independent pressure protrusion 230 is formed in a needle shape with a sharp tip on the lower surface of the pressure body 210 so as to dig into the upper surface of the suction plate 100, it easily digs into the upper surface of the absorption body 110 of the suction plate 100. . In particular, the independent pressure protrusion 230 in the shape of a sharp needle gradually digs deeply into the upper surface of the suction body 110 of the suction plate 100 made of a soft material to prevent the pressure plate 200 from sliding or rotating on the top surface of the suction plate. can In addition, for example, even if the pressure body 210 is pulled by a load applied to one side by hanging an object on the hook part 240 protruding to one side of the pressure body 210, the independent pressure protrusion 230 of the pressure body 210. The pointed needle does not deviate from the initial pressing position of the upper surface of the absorption body 110 of the suction plate 100 and maintains it, more effectively prevents the pressure plate 200 from sagging to one side, and also prevents the suction plate 100 from being further stretched.

And the end of the sharp and sharp needle of the independent pressure protrusion 230 gradually digs deeper into the upper surface of the suction plate 100 as time elapses while the pressure plate 200 presses the suction plate 100, and the end of the sharp needle In addition to holding the digging position more firmly, the suction plate 100 is more closely attached to the adherend surface 20 to maintain a stable absorption state for a long time.

In addition, the plurality of independent pressing protrusions 230 perform a function of distributing the load when the pressing plate 200 presses the suction plate 100, as well as the independent pressing projections 230 of the pressing plate 200 in the shape of a sharp needle. When the ground load is applied to one side, even if the other side of the pressing plate 200 is slightly apart, the needle end of the independent pressing protrusion 230 is deeply embedded in the suction plate 100, so it is induced to faithfully perform the pressing function.

The independent pressing protrusion 230 of the pressing plate 200, which can be formed in various shapes as described above, is independent of the pressing body 210 of the pressing plate 200 in consideration of the increase in the surface contact area between the suction plate 100 and the pressing plate 200. It is also possible to replace the pressure protrusion 230 with a concave contact groove (not shown) or to form a contact groove together in the space between the independent pressure projections 230 , and the pressure body 210 of the pressure plate 200 . ) It is also possible to replace the independent pressing protrusion 230 formed on the lower surface with an adhesive layer (not shown) or to form an adhesive layer together in the space between the independent pressing projections 230, and this degree of design change is also It is natural to fall within the scope of the present invention.

And the pressure plate 200, along the edge of the penetrating portion 220, the support portion 222 to which the lower end of the edge of the tightening member 300 is pressed upwardly protrudes. Such a support part 222 can also be expected to prevent distortion of the pressing plate 200 and to reinforce the strength. A receiving space 224 is formed in the lower portion of the support part 222 so that when the periphery of the center of the adsorption body 110 is pulled toward the upper center, it gently flows into the adsorption body 110 into the receiving space 224 to the adsorption body. It can be prevented from being damaged by rubbing against the pressure body 210 while the 110 is sharply bent.

In addition, the pressing body 210 may further extend integrally with a hanging part 240 that can hang an object on one side, for example, if necessary. The hook 240 is preferably formed integrally with one side of the rim of the pressing body 210 , but may be formed at various positions of the pressing body 210 as needed. In this case, the hook 242 for hanging an object may be integrally formed at the end of the hook 240, and, although not shown in a separate drawing, may have a structure having a simple circular hook hole.

Therefore, the hook 240 may be formed in various forms for hanging things other than a hook and a hanging hole, and it is also possible to adopt a structure that can be attached to and detached from the pressure body 210 as necessary, and this degree of It is natural that all design changes also fall within the scope of the present invention.

According to this structure, the head portion 120 of the suction plate 100 is initially pushed into the through portion 220 of the pressure plate 200 to expose the upper portion, and then the tightening member 300 is screwed with the head portion 120 . When it is tightened, the lower end of the tightening member 300 is supported by the support portion 222 of the pressing plate 200 and the head 120 rises. At this time, when the tightening member 300 is screwed to the head 120 and tightened, the head 120 is pulled upward, but the pressure body of the pressure plate 200 while the tightening member 300 is relatively lowered ( 210) is pressed in the direction of the suction plate 100.

The tightening member 300 is a head inlet portion ( 310) is formed. At this time, the shape of the male thread 122 formed on the outer peripheral surface of the head 120 of the suction plate 100 and the female thread 312 formed on the inner peripheral surface of the head inlet 310 of the tightening member 300 has a triangular cross section. Although only a triangular screw thread is shown, it is not limited thereto, and a square screw thread having a square cross section can be applied, and such design changes all fall within the scope of the present invention. In addition, it is preferable that the anti-slip irregularities 314 are formed on the outside of the tightening member 300 to prevent slipping when turning by hand.

According to this, as the tightening member 300 is screwed with the suction plate 100, the head 120 of the suction plate 100 is pulled upward, and a stronger vacuum pressure is concentrated on the central lower part 111 of the suction plate 100. The adsorption force to the adherend surface 20 is increased, so that a strong adsorption force can be maintained for a long time.

In addition, the head inlet 310 of the tightening member 300 has a central support protrusion 320 inserted into the support groove 124 formed in the upper center of the head 120 of the suction plate 100 downwards. . At this time, the support groove 124 formed in the head 120 of the suction plate 100 is formed in a circular shape, and the central support protrusion 320 is formed in a cylindrical shape to smoothly rotate the tightening member 300 . have. The tightening member 300 may be injection-molded with a synthetic resin material, and the central support protrusion 320 may further have a slimming groove 322 to reduce material consumption. Of course, the tightening member 300 may be made of a metal material in addition to the synthetic resin material, and a known synthetic resin material or a metal material nut may be used.

According to this structure, the central support protrusion 320 of the tightening member 300 in the support groove 124 formed in the head 120 of the suction plate 100 when the tightening member 300 is screwed to the suction plate 100. As is slowly inserted, the head 120 of the suction plate 100 is separated from the head inlet 310 of the tightening member 300 or the shape is distorted to minimize deformation while the suction plate 100 and the tightening member 300 are Stable and firmly screwed together.

On the other hand, when a long time elapses in a state in which the tightening member 300 is tightened to the suction plate 100 , the male thread 122 of the suction plate 100 is pressed against the female thread 312 of the tightening member 300 . The member 300 cannot be easily loosened. Accordingly, the male thread 122 formed on the head 120 of the suction plate 100 or the female thread 312 formed on the head inlet 310 of the tightening member 300 has various types of slippery materials such as grease and soap ingredients. The suction plate 100 and the tightening member 300 are screwed in a state in which a lubricant consisting of This structure makes it possible not only to easily fasten the tightening member 300 to the suction plate 100, but also to attach the tightening member 300 to the suction plate 100 even if a long time elapses in a state in which the tightening member 300 is tightened to the suction plate 100. It can be easily separated from the , and it is also possible to prevent damage to the suction plate 100 .

The vacuum suction port 1 having the above structure is a clamping member 300 in a state in which air is removed by adhering the lower surface of the suction plate 100 to the adherend surface 20 of the adherend 2 such as glass, mirror, tile, furniture, etc. is tightened in one direction, while the head 120 of the suction plate 100 rises and is guided to the head inlet 310 of the tightening member 300, and at the same time, the tightening member 300 is relatively descended and the pressure plate 200 The support part 222 is pressed, and a plurality of independent pressing protrusions 230 provided on the lower surface of the pressing plate 200 press the suction plate 100 . When the tightening member 300 is continuously tightened in this way, the head 120 is further pulled upward and at the same time the independent pressing protrusion 230 further presses the upper surface of the suction plate 100, thereby further pressing the lower center of the suction plate 100. Since the vacuum pressure is further concentrated at (111), the adsorption force on the adherend surface 20 is increased, so that a strong adsorption force can be maintained for a long time.
