Description

  TECHNICAL FIELD The present invention relates to a vacuum suction tool that attaches and fixes an object to the surface of an adherend such as a tile or a glass surface using atmospheric pressure, and in particular, sand or the like on an adherent wall or tile surface. The present invention relates to a vacuum suction tool that can be easily attached even if such an object is present to some extent and can maintain a firmly attached state.

  In general, a vacuum suction tool 200 that is attached to the surface of an adherend such as a tile wall or a glass surface and is fixed and applied or supported is shown in FIGS. 8 (a) and 8 (b). As shown in the figure, the body 220 is formed with a hollow portion and a through-hole is formed in the center, and the front surface of the body 220 (the lower surface in FIGS. 8A and 8B) is stable at the open portion. And a rotating tool 250 provided with a nut 251 fastened to the bolt 241 passing through the through hole. The suction plate 243 is made of soft rubber, and when the suction plate 243 moves upward in FIGS. 8A and 8B, the suction plate 243 is also pulled upward in the center thereof. It is done. In this way, it is formed between the lower surface of the suction plate 243 and the surface of the adherend to which the vacuum suction tool 200 is attached, and depending on the peripheral edge on the open side of the main body 220 and / or the peripheral edge of the suction plate 243. A negative pressure is generated in the sealed hollow portion, whereby the vacuum suction tool 200 adheres to the wall surface or tile surface to be adhered.

  In such a conventional vacuum suction tool 200, since the suction plate 243 must be made of a soft and soft material, there is a limit to the weight that can be supported. When the suction tool 200 is detached from the wall surface or tile surface to be attached and the load acting on the suction tool 200 is generated in a direction perpendicular to the bolt 241, the suction plate 243 is often twisted and separated. There is a problem.

  In order to solve the above-described problems, an adsorbing tool is proposed in which the structure of the suction plate is made hard and packing is additionally provided on the edge of the suction plate. An adsorption tool using such a hard adsorption plate is shown in FIGS. 9 (a) and 9 (b).

The improved vacuum suction tool 300 has a suction plate 343 made of a hard material to increase durability, and the suction plate 343 is pulled upward at the center thereof, and the lower surface of the suction plate 343, It is ensured that air flows into the hollow portion formed between the surface of the adherend to which the vacuum suction tool 300 is attached and sealed by the peripheral edge of the open side of the main body 320 and / or the peripheral edge of the packing 330. In order to shut off, a portion indicated by reference numeral 330 is added. That is, when the packing 330 is stably attached to a portion where the suction plate 343 formed into a rigid shape and the main body 320 are in contact with each other, and the suction plate 343 is moved upward by the bolts 341, the suction plate 343 is moved at the center thereof. Pulled in the upward direction and formed between the lower surface of the suction plate 343 and the surface of the adherend to which the vacuum suction tool 300 is attached, the peripheral edge on the open side of the main body 320 and / or the packing 330. A negative pressure (-pressure) is generated in the hollow portion sealed by the peripheral edge, and the vacuum suction tool 300 is attached to the tile and the wall surface.

  However, the vacuum suction tool 300 shown in FIGS. 9 (a) and 9 (b) rotates the rotating tool 350 to adhere to the wall surface, and the bolt 341 is moved upward in FIGS. 9 (a) and 9 (b). When moving toward, the suction plate 343 moves upward, and the packing 330 is pressure-bonded. At this time, the lower surface of the packing 330 in the surface where the packing 330 is crushed and is in close contact with the wall surface (FIG. 9b). ), Fine wrinkles are generated. Therefore, when sand or fine foreign matter is present on the surface of the adhered object, there is a problem that the wrinkles are often separated.

  Therefore, the present invention has been devised to solve the above-mentioned problems, and the object of the present invention is to adhere firmly even if foreign matter adheres to the surface to which the vacuum suction tool adheres.

  The packing 30 is made of a soft material, that is, in the vacuum suction tool 10 according to the present invention, the suction plate 43 is moved upward from the state shown in FIG. 5A as shown in FIG. ) And (b), the packing 30 is moved from the state shown in FIG. 5 (a) to the state shown in FIG. 5 (b) due to the presence of the buffer groove 31. It consists of a member made of a material having a degree of softness that can be deformed. For example, the packing 30 can be formed of a soft material such as isobutylene, isoprene, or rubber.

  The adsorbing member 40 is formed of a hard material, and an adsorbing plate 43 in which the upper side of the periphery (upper side in FIG. 2) partially overlaps the lower side surface of the packing 30 as shown in FIG. 5A. And a bolt 41 attached upward to the central portion on the upper side of the suction plate 43.

  The suction plate 43 is a hard material, that is, in the vacuum suction tool 10 of the present invention, from the state shown in FIG. 5A, as shown in FIG. a) and (b) in the upward direction), and the shape is deformed even if the hollow portion formed between the bottom surface of the suction plate 43 and the wall surface to which the vacuum suction tool 10 is attached is in a negative pressure state. It is made of a material made of a material having such a degree of hardness that it does not. For example, the adsorbing plate 43 can be formed of a hard material such as a glass fiber reinforced nylon resin made of 70% nylon single and 30% glass, or 70% nylon double and 30% glass.

  The rotating tool 50 includes a nut 51 therein, and is fastened with the bolt 41 of the suction member 40 that has passed through the through hole 21 of the main body 20 from the lower side toward the upper side.

  In the vacuum suction tool 10 of the present invention, the opened lower side of the main body 20 is attached to the surface of an adherend (for example, a wall surface, a tile surface, a glass surface, etc.), and the bolt 41 of the suction member 40 is attached. And the nut 51 of the rotating tool 50 are tightened, the suction plate 43 moves in the upper side direction (upward direction in FIGS. 5A and 5B), and the lower surface of the suction plate 43 and the above-mentioned There is a hollow portion sealed with the periphery of the main body 20 and / or the periphery of the packing 30 between the surface of the adherend (for example, the wall surface, tile surface, glass surface, etc.). Is formed. Here, in the vacuum suction tool 10 of the present invention, the “hollow part” indicates that the suction plate 43 is directed upward from the state shown in FIG. 5A as shown in FIG. 5B (FIG. 5A). , (B) upward direction), the bottom surface of the suction plate 43, and the surface of the adherend to which the vacuum suction tool 10 is attached (for example, the wall surface, the surface of the tile, the surface of the glass, etc.) It is a part formed between.

  In the vacuum suction tool 10 of the present invention, a buffer groove 31 having a predetermined depth is formed in an annular shape on the upper surface of the packing 30 along the periphery of the packing 30 that is in close contact with the periphery on the open side of the main body 20. When the upper side of the packing 30 is in close contact with the lower side of the open side of the main body 20 at a predetermined distance from the peripheral edge on the lower portion side of the main body 20, the buffer groove 31 is used for the packing. The fixed ring 25 is formed toward the lower part side in a part that is separated from the position formed at 30 by a distance closer to the center part side.

  Here, the buffer groove 31 is formed on the upper surface of the packing 30, a predetermined distance from the peripheral edge on the lower portion side of the main body 20, a predetermined depth of the buffer groove 31, and a lower portion side fixing ring 25 of the main body 20. The predetermined distance from the peripheral edge of the lower portion side of the main body 20 at a portion where the seal 30 is formed is such that when the packing 30 that is stably attached to the main body 20 from the lower side of the main body 20 is pressure-bonded. The lower end portion of the packing 30 is protruded downward (toward the surface of the adherend to which the vacuum suction tool 10 is adsorbed), and the end portion of the packing 30 thus protruded is due to the presence of the buffer groove 31. As shown in FIG. 5 (b), it can be determined within a range in which it is possible to adhere to the surface of the adherend without distortion. As a result, the tightness of the adhering surface is enhanced, and even when there is sand or foreign matter, the hermeticity is enhanced, and the suction plate 43 is pulled upward at the center thereof, and the lower surface of the suction plate 43 The air is surely flown into the hollow part formed between the surface of the adherend to which the vacuum suction tool 10 is attached and sealed by the peripheral edge of the open side of the main body 20 and / or the peripheral edge of the packing 30. The solid adsorption state can be maintained over a long period of time.

  Specifically, the main body 20 has a dish shape in which an open part is formed on the lower side in FIGS. 1 and 2, and a through hole 21 through which a bolt 41 can penetrate is provided in the center part, and an inner edge is provided. Is formed with a fixed ring 25 (FIGS. 4, 5A and 5B) for securing a space in which the packing 30 is stably mounted, and a reinforcing rib 23 (FIGS. 4 and 5) inside. 5 (a)) is formed to increase the durability. The main body 20 is formed of a hard material such as the above-described glass fiber reinforced nylon resin so that the shape does not deform even when a negative pressure (minus pressure) is generated in the above-described hollow portion.

  The adsorbing member 40 is stably attached to the open portion (lower side in FIGS. 1 and 2) of the main body 20. The suction member 40 includes a suction plate 43 and a bolt 41. The suction plate 43 has a disc shape and is made of a hard material. The bolt 41 does not penetrate the suction plate 43, but the bolt head is embedded in the suction plate 43 so that there is no space between the bolt 41 and the suction plate 43 in which air can flow.

  Since the vacuum suction tool 10 of the present invention is configured to absorb using atmospheric pressure, it is important to maintain hermeticity.

  The packing 30 is stably attached to the portion where the suction plate 43 and the main body 20 are in contact with each other in order to maintain the hermeticity. The packing 30 will be described in detail below with reference to FIG.

  The packing 30 is formed in a ring shape with a flat bottom surface (lower surface in FIGS. 1, 2, and 3 (c)) that is in direct contact with a tile and a wall surface. The contact surface 33 that comes into contact with the surface is formed to be slightly inclined.

  When the packing 30 is stably attached to the main body 20, the front part of the packing 30 (the lower side part in FIGS. 5A and 5B) protrudes and can be attached in a stable manner so that it can be stably attached. A short end surface 35 is formed on the side surface of the packing 30 (FIG. 3C). That is, a short edge that is stably attached to the end of the main body 20 is formed, and the contact surface 33 is formed below the side surface of the short end (see FIG. 3C). (See enlarged view of the main part).

  Further, a buffer groove 31 is formed on the upper surface of the packing 30 (the upper surface in FIGS. 1, 2, and 3 (c)). The buffer groove 31 has a circular shape (that is, an annular shape). As shown in FIGS. 5A and 5B, when the packing 30 is pressure-bonded by the suction plate 43, it serves to facilitate pressure bonding up and down.

  The rotary tool 50 has a shape in which a nut 51 is embedded therein, and the nut 51 is secured to a sufficient length so that the bolt 41 to be tightened can move upward (in FIG. 1 and FIG. 2). . A washer is attached to the front surface of the nut 51 of the rotating tool 50 (the lower side in FIGS. 5A and 5B).

  The operation of the above-described configuration of the present invention will be described in detail with reference to FIGS. 5 (a) and 5 (b).

  The packing 30 is stably attached to the front surface opening portion edge of the main body 20 (the lower peripheral edge in FIGS. 5A and 5B), and the bolt 41 of the suction member 40 is inserted into the through hole. 21 (FIG. 2) can be penetrated. The packing 30 is in close contact with the tile or the wall surface with the rotating tool 50 tightened on the penetrating bolt 41 (FIG. 5A), and the rotating tool 50 is rotated.

  When the rotating tool 50 having the nut 51 seated therein rotates, the tightened bolt 41 moves to the upper part (upper side in FIGS. 5A and 5B), and the packing 30 is crimped by the suction plate 43. To come. When the packing 30 supported by the fixed ring 25 of the main body 20 is pressure-bonded, the shape is deformed by the buffer groove 31 and the part where the contact surface 33 is formed is the front side (the lower side in FIGS. 5A and 5B). The space that is projected to block air and is sealed is expanded by the suction plate 43 that moves in the upper direction (upper direction in FIGS. 5A and 5B) as described above, Negative pressure is generated between the tile and the wall.

  Therefore, the negative pressure formed in the inside of the adsorbing tool 10 (in FIG. 5 (b), the tile or wall surface existing on the lower side in the drawing and the periphery thereof are closed by the peripheral portion of the packing 30, and the upper portion is adsorbed by the adsorbing plate 43. The suction device 10 is fixed to the tile or the glass surface by the difference between the negative pressure generated in the space portion closed by the pressure and the external atmospheric pressure (FIG. 5B).

  In order to remove the adsorbing tool 10 attached to the tile or the wall as described above, the rotating tool 50 is rotated in the opposite direction to the bolt 41 below (in FIGS. 5A and 5B). , Move downward). By the bolt 41 thus moved, the suction plate 43 is also moved downward, the space of the hollow portion where the negative pressure was formed is reduced, and the pressure is increased to the original atmospheric pressure. . In the hollow portion (in FIG. 5 (b), the tile or wall surface existing on the lower side, and the space portion in which the periphery is closed by the peripheral portion of the packing 30 and the upper portion is closed by the suction plate 43). When the pressure recovers to the atmospheric pressure, the internal and external air pressures become the same, the pressure generated by the pressure difference acting on the adsorber 10 disappears naturally, and the adsorber 10 is separated from the tile and the wall surface. become.

  Although the suction tool 10 according to the present invention can be used in a plurality of ways, as shown in FIGS. 6 and 7, the end of the connection tool 500 can be seated between the rotary tool 50 and the main body 20. You can leave it.
