The present invention relates to a vacuum adsorption apparatus, and more particularly, to a vacuum adsorption apparatus capable of fixing a protective layer on the impact surface for protection of an impact surface exposed to an external impact such as a wall surface.

When a heavy object is moved through a space such as an elevator or a corridor, it is necessary to prevent damage to the wall or floor caused by the impact of the object. For this purpose, a temporary protective layer may be installed on the wall or the bottom, and in particular, in the case of installing the protective layer on the wall, a fixing device capable of fixing the protective layer is required. Such fasteners must meet several conditions that the protective layer is often installed temporarily.

First, the fixing device must not damage the wall itself. The use of screws ensures a firm fixation of the protective layer, but they are difficult to use because the walls can be damaged. And it should have detachability and ease of installation. In cargo-only lifts, the protective layer can be permanently installed on the wall, but in most cases the protective layer is only installed if the object is transported. In addition, in the case of tenant housing such as an apartment, it can be installed for a relatively long time, but in this case, it must be removed when the occupancy expires and it is necessary to install the object again. As such, most of the protective layer is temporarily installed on the wall and must be removed after the transfer of the object, so that the protective layer must have separation and ease of installation. As a fixing device that satisfies these conditions, a vacuum suction port such as shown in Fig. 5 is known. Known vacuum suction holes are mainly intended for fixing objects to walls and for permanent fixing. Referring to FIG. 5, a known vacuum suction port is fixed to a pressure plate 2 and a suction plate 1 including a suction plate 1 of a stretchable material in contact with a wall surface and a pressing plate 5 formed above the suction plate 1. And a cover 4 which can be engaged with the coupling bolt 3 and the coupling bolt 3 which protrudes through the pressing plate 2. Known vacuum adsorption holes are used for hanging objects rather than for securing the protective layer substantially. Therefore, it is difficult to apply a vacuum suction port for fixing the protective layer. Tools for fixing the protective layer are not specifically known in the art and are referred to herein as vacuum adsorption devices. As already explained above, the vacuum adsorption device has a different function than the vacuum adsorber and therefore has to have different features. In addition to features such as wall protection and ease of separation, the vacuum adsorption device has to be able to be prevented from damage. Damage to the vacuum adsorption device can occur due to collisions with other objects, for example, protruding from the wall. And, for example, when the hobo layer is fixed to the wall of the elevator by the vacuum adsorption device, there is damage such as when people separate the vacuum adsorption device for reasons such as curiosity.

The present invention proposes a vacuum adsorption device capable of protecting the wall surface, ease of separation, and prevention of damage.

An object of the present invention is the vacuum adsorption for fixing the wall of the protective layer, which can be protected by the adsorption plate wall, easy to install and detach using the coupling bolt and fasteners, and can prevent damage by forming the assembly groove To provide a device.

According to a preferred embodiment of the present invention, in a vacuum adsorption apparatus including a suction plate in contact with a wall, a pressing plate with a pressing ring, a coupling bolt fixed to the suction plate and protruding through the pressing plate, and the fixture is provided on the upper surface. A coupling head in the form of a truncated cone or pyramid with an assembly groove; And a threaded engagement leg extending downward from the engagement head and capable of engagement with the engagement bolt, wherein the cross section of the assembly groove is polygonal and the depth of the assembly groove is from 1/2 to the height of the fixing head. 4/5.

According to another suitable embodiment of the present invention, the cross section of the assembling groove has a pentagonal shape or a triangular shape.

According to still another embodiment of the present invention, it further includes a fastening device that can be fastened to the assembly groove to rotate and fix the fixture.

According to another suitable embodiment of the invention, it further comprises an O-ring fitted to the engaging leg.

According to another suitable embodiment of the invention, it further comprises an intermediate fastening screw coupled to the assembling groove to enable tightening with the automatic tightening device.

Hereinafter, the present invention will be described in detail using the embodiments set forth in the accompanying drawings. The examples presented are exemplary and are not intended to limit the scope of the invention.

Figure 1 shows an exploded perspective view of the vacuum adsorption apparatus according to the present invention.

Referring to FIG. 1, the vacuum adsorption device includes a suction plate 10 contacting a wall surface, a pressing plate 12 formed on an upper side of the suction plate 10, and a coupling bolt fixed to the suction plate 10 and protruding through the pressing plate 12. And a fixture 14 that can be engaged with the coupling bolt 101. And the pressing ring 11 is formed along the circumferential edge of the disk pressing plate 12 can prevent the inflow or outflow of air from the side.

Suction plate 10 may be a circular plate having a thin thickness, and is made of a flexible plastic, ceramic or rubber material. In addition, the coupling bolt 101 is fixedly coupled to the center of the upper portion of the suction plate (10). The suction plate 1 has a convex center portion and an edge extending in a plane. The pressing plate 12 is installed above the suction plate 10 and maintains the overall appearance of the suction device. The central portion of the pressure plate 12 is raised upwards to form an empty space of a predetermined size between the suction plate 10 and the pressure plate 12, the edge portion of the pressure plate 12 is the edge portion of the suction plate 10 The plane is extended so that a portion can come into contact with. In addition, an extension protrusion 121 extending in a radial direction of the pressing plate 12 may be formed on an upper surface of the pressing plate 12. The extension protrusion 121 is formed to prevent deformation of the pressing plate 12 itself when the pressure is applied by the fixture 14 of the pressing plate 12. The extension plane of the pressure plate 12 extends further beyond the extension plane of the suction plate 10 and the compression ring 11 is engaged at the bottom of the additional extension portion. The compression ring 12 may be made of soft synthetic resin or rubber material and preferably made of polyurethane or ethyl vinyl acetate.

Fixture 14 includes a coupling head 141 and a coupling leg 142 that is threaded therein to engage with the coupling bolt 101. The protective layer C in which the through hole H is formed is fixed to the upper side of the pressing plate 12 by using the coupling bolt 101. The threaded portion of the coupling bolt 101 passing through the through hole H is coupled to the thread formed on the coupling leg 142 of the fixture 14 to fix the protective layer C to the wall surface. An assembly groove 143 may be formed in the coupling head 141 to tighten the fixture 14. The overall shape of the coupling head 141 of the fixture 14 is in the form of a truncated truncated cone or pyramid at the bottom and the assembly groove 143 is formed on the top of the truncated truncated cone or pyramid.

When the height of the coupling head 141 is high, it is possible to rotate by manual operation, and when installed, there is a fear that the fixing of the protective layer (C) is unstable by the manual operation of a person and also loses the fastener 14 itself. Therefore, it is advantageous that the fixture 14 is difficult to be manually engaged with the coupling bolt 101 so that it can be engaged and fixed by a special device. An assembly groove 143 is formed for the engagement and fixation by such a special device. Assembly groove 143 is formed to have a constant height into the interior of the coupling head 141 in the form of a triangular or pentagonal. Coupling head 141 may be a truncated cone or pyramid having a height of 1 to 3 cm, the assembly groove 143 may be formed to have a depth slightly smaller than the height of the coupling head 141. Preferably, the depth of the assembly groove 143 may be 1/2 to 4/5 of the height of the coupling head 141. The setting of the depth of the assembling groove 143 is such that the fixture 14 is not easily separated from the coupling bolt 101 by manual operation. Fixture 14 may be made of a material of reinforced plastic, ceramic or rubber material to prevent damage from impact.

The form and dimensions of the fixture 14, coupling head 141 or coupling legs described above are exemplary and are not intended to limit the scope of the present invention. In addition, the shape or depth of the assembling groove 143 is also possible to change the design by those skilled in the art is not set to limit the scope of the present invention. In addition, the description of the material is the same.

The coupling leg 143 is inserted into the hollow drum-shaped hole drum 13 installed in the protective layer C to be engaged with the coupling bolt 101. The hole drum 13 is inserted and fixed inside the protective layer C to form the through hole H of the protective layer C. And the hole drum 13 prevents the surface portion of the protective layer (C), which may be made of fabric in the form of piles, from being damaged by being caught in the pressing plate 12 and the fixture 14. The hole drum 13 may be made of the same material as the fixture, plastic, metal or alloy material.

In the vacuum adsorption apparatus according to the present invention, the protection layer C is fixed to the wall by the coupling of the fixture 14 and the coupling bolt 101 and the coupling of the fixture 14 and the coupling bolt 101 uses a tightening device. Can be.
