The adsorption port 100 includes an adsorption plate 110 attached to an installation target surface 10 (eg, a glass surface, a tile surface, etc.), a post 120 protruding upward from the center of the adsorption plate 110, and a post 120. It includes an accommodation space 130 formed to be opened upward in the interior.

Adsorption plate 110 is formed in a circular plate shape, the center of which slightly protrudes upward, the inner stiffener (111) formed integrally with the post 120, and a skin surrounding the stiffener (111) 112).

The stiffeners 111 are made of a synthetic resin material such as polycarbonate having excellent elasticity, and have a centered convex shape. As a result, the post 120 is elastically deformed in a flat state by pressing the post 120 toward the installation target surface 10.

If necessary, the stiffeners 111 may have a circular plate shape or may have a structure such as a plurality of spokes arranged radially with respect to the center of the post 120.

The locking groove 140 may have a shape in which an inner wall of the accommodation space 130 is recessed for a predetermined period or penetrates the post 120 laterally. It is preferable that the locking groove 140 is formed in two or more along the circumference of the receiving space 130.

The fixing member 200 has a substantially cylindrical shape and is coupled to an upper portion of the accommodation space 130.

In the center of the fixing member 200 is inserted through the insertion hole 210 is inserted into the rod 310 of the piston member 300 to be described later.

And on the outer circumferential surface of the fixing member 200 is formed a locking projection 220 to enter the locking groove 140 of the suction hole 100 when the fixing member 200 and the suction hole 100 is coupled.

The locking protrusion 220 is formed in a wedge shape having a thin lower side and a thick upper side so that the fixing member 200 can be easily inserted into the accommodation space 130.

For this purpose, the fixing member 200 has a structure in which portions located at both sides of the locking protrusion 220 are cut up and down. According to this, when the fixing member 200 is inserted into the accommodation space 130, a portion where the locking protrusion 220 is formed may be easily inserted by elastically deforming inward.

The upper end of the fixing member 200 is formed with a latching flange 230 protruding along the outer circumference. The locking flange 230 is in contact with the upper surface of the post 120 in a state that the locking projection 220 enters the locking groove 140, and thus the fixing member 200 is inserted into the upper portion of the receiving space 130 Is further inserted into the lower portion of the receiving space 130.

On the other hand, in the embodiment of the present invention as described above, the fixing member 200 and the suction port 100 has a structure coupled to each other by the locking projection 220 and the locking groove 140.

However, this is disclosed as an example of the coupling structure of the fixing member 200 and the suction port 100, the fixing member 200 and the suction port 100 in the present invention, the fixing member 200 is the suction port 100 Inserted into the receiving space 130 from the upper side of the can be coupled to each other in a variety of structures within the fixed range.

For example, by forming a male screw on the outer circumferential surface of the fixing member 200, and by forming a female screw on the inner circumferential surface of the post 120 of the suction hole 100, the fixing member 200 and the suction hole 100 are screwed together. Could be employed.

The piston member 300 is formed in the lower portion of the rod 310 and the lower end of the rod 310, the rod 310 is slidably inserted into the insertion hole 210 of the fixing member 200 in contact with the lower inner peripheral surface of the receiving space 130 It comprises a head 320 is made.

The rod 310 is formed in a circular rod shape, and a male screw for coupling with the push member 400 is formed at an upper end thereof.

The head 320 has a shape in which a cross-sectional area is extended along the outer circumferential surface of the lower end of the rod 310, protrudingly formed along the outer circumferential surface at the lower end of the rod 310, and arranged below and spaced apart from each other. It comprises an upper flange 322, and a packing 323 coupled to surround the lower flange 321.

Here, the packing 323 has a bottom portion 323a surrounding the bottom surface of the lower flange 321 and a side wall portion 323b formed upwardly protruding along the edge circumference of the bottom portion 323a to surround the outer circumferential surface of the lower flange 321. The locking portion 323c is formed to protrude along the inner circumferential surface of the upper end portion of the side wall portion 323b and enters between the lower flange 321 and the upper flange 322, and an accommodation space at the upper end of the side wall portion 323b. It includes a raised portion 323d protruded obliquely upward to contact the inner peripheral surface of the portion 130.

The packing 323 is made of an elastomeric material, such as the skin 112, and the side wall portion 323b is formed to be in non-contact with the inner circumferential surface of the accommodation space 131, between the bottom portion 323a and the locking portion 323c. The space of is formed larger than the thickness of the lower flange 321.

Accordingly, in the packing 323, as shown in FIG. 4, the ridge 323d contacts the inner circumferential surface of the accommodation space 130 to block air flow between the upper side and the lower side of the head 320, and the piston member ( 5 and 6, the upper flange 322 presses the upper surface of the locking portion 323c to deform the side wall portion 323b to the inner side, thereby raising the raised portion 323d to the accommodation space portion. The air from the upper side and the lower side of the head 320 may flow away from the inner circumferential surface of the 130. In addition, when the piston member 300 is raised, the lower flange 321 lifts the lower surface of the locking portion 323c and the side wall portion 323b is deformed outward so that the raised portion 323d is the inner circumferential surface of the accommodation space 130. As a result, the sealing force between the upper side and the lower side of the head 320 is further increased.

Push member 400 is coupled to the upper end of the rod 310, and protrudes to the upper side of the suction port 100 so that the user can press the piston member 300 and the post 120.

When the piston member 300 descends from the receiving space 130 by a predetermined period, the push member 400 descends together with the piston member 300 to come into contact with the upper surface of the post 120.

Compression spring 500 is made of a known compression coil spring, it is interposed between the fixing member 200 and the push member 400 to exert an elastic force in the direction in which the piston member 300 rises.

As a result, the one-touch adsorption unit according to the embodiment of the present invention having the above structure has a fixed member 200, a piston member 300, a push member 400, and a compression spring 500 as shown in FIG. 3. In the state where the assembly A is coupled to each other to form one assembly A, the assembly A is inserted into the accommodation space 130 from the upper side of the suction member 100 and the fixing member 200 and the piston member 300. It can be coupled to the adsorption port 100 by.

According to this, the assembly of each part can be made in the state in which the protective film is attached to the lower surface of the adsorption plate 110, thus the contamination or damage of the adsorption plate can be prevented during the assembly process, each component can be easily assembled, Productivity can be improved by modularizing the assembly work.

In addition, the assembly (A) is inserted into the receiving space 130 from the upper side of the suction port 100 is coupled to the suction port 100, the structure of the lower side of the suction port 100 is free to change, therefore, Figure 8 As shown in FIG. 11, the adsorption performance may be improved by providing a configuration of the partition wall 150 and the lower valve member 700 in the center of the adsorption plate 110.

Hereinafter, the installation process of the one-touch adsorption unit according to the embodiment of the present invention having the above configuration will be described with reference to FIGS. 4 to 7.

First, as shown in FIG. 4, the push member 400 is pressed to contact the upper surface of the post 120 in a state in which the lower surface of the suction plate 110 faces the installation target surface 10 (hereinafter, initially pressurized). When the compression spring 500 is compressed and deformed as shown in FIG. 5, the push member 400 and the piston member 300 are lowered, and the air filled below the head 320 is Passing between the packing 323 and the inner circumferential surface of the receiving space 130 is moved to the upper side of the head 320.

Subsequently, when the push member 400 is further pressed (hereinafter referred to as final pressurization) so that the post 120 in contact with the push member 400 is lowered, as shown in FIG. 6, the adsorption plate 110 is flat. It is elastically deformed and adhered to the installation target surface 10. At this time, the air filled between the suction plate 110 and the installation target surface 10 passes through the head 320, and then the gap between the post 120 and the fixing member 200, and the fixing member 200 and the rod ( 310 is discharged to the outside through the gap.

Subsequently, when the pressure applied to the push member 400 is released, the push member 400 and the piston member 300 are raised as the compression spring 500 which is compressed and deformed as shown in FIG. 7 is restored. At this time, as the side wall portion 323b of the packing 323 is deformed to the outside, the air flow of the upper side and the lower side of the head 320 is blocked.

In this state, negative pressure is generated between the adsorption plate 110 and the installation target surface 10 by the elastic restoring force of the adsorption plate 110, and is also installed with the adsorption plate 110 by the elastic restoring force of the compression spring 500. The negative pressure between the object surface 10 can be maintained.

And when the adsorption force of the adsorption unit is lowered, the user can easily recover the reduced adsorption force only by one-touch pressing the push member 400.

Meanwhile, as illustrated in FIGS. 8 to 11, the one-touch type adsorption unit according to the embodiment of the present invention is formed in the center of the adsorption plate 110 to partition partition walls 130 and the lower side of the adsorption plate 110. 150, a vent hole 160 formed at the center of the barrier wall 150, and a lower valve member 700 formed on an upper surface of the barrier wall 150 to open and close the vent hole 160. .

The partition wall 150 is formed by the stiffener 111 extending into the post 120, and the skin 112 may be covered by the partition wall 150 as necessary.

The lower valve member 700 is made of a rubber material, and one end thereof is attached to the partition wall 150 to cover an upper surface of the partition wall 150.

Accordingly, the lower valve member 700 closes the vent hole 160 as shown in FIG. 9 by increasing the air pressure between the head 320 and the partition wall 150 when the push member 400 is initially pressed. State is maintained. At this time, the air between the head 320 and the partition wall 150 passes between the inner circumferential surface of the accommodating space 130 and the side wall 323b as the side wall 323b of the packing 323 is deformed inward. It is moved above 320.

In addition, the lower valve member 700 maintains a state in which the vent hole 160 is closed even at the final pressurization of the push member 400, as shown in FIG. 10, and at this time, the suction plate 110 and the installation target surface 10. At the same time as the adsorption plate 110 is elastically deformed, the air between the s) escapes between the edge of the adsorption plate 110 and the installation target surface 10.

When the pressure applied to the push member 400 is released, the push member 400 and the piston member 300 are raised as the compression spring 500 is compressed and deformed as shown in FIG. As the side wall portion 323b of the 323 is deformed to the outside, the air flow of the upper side and the lower side of the head 320 is blocked, and the compression spring 500 is disposed between the lower side of the head 320 and the partition wall 150. The negative pressure is generated by the elastic restoring force.

In this state, the lower valve member 700 opens the vent hole 160 when the air pressure between the suction plate 110 and the installation target surface 10 becomes higher than the air pressure between the head 320 and the partition wall 150. The air between the suction plate 110 and the installation target surface 10 can escape between the head 320 and the partition wall 150, and the air pressure between the suction plate 110 and the installation target surface 10 is increased by the head ( When the air pressure between 320 and the partition wall 150 is similar to or lower than that of the air vent 160, the air pressure between the suction plate 110 and the installation target surface 10 is kept constant.

As a result, according to the structure as described above, the negative pressure of the lower side of the suction plate 110 can be maintained more stably by the partition wall 150 and the lower valve member 700, and the internal pressure is repeatedly pushed by the push member 400. By further discharging, the adsorption force can be further increased.

Hereinafter, the one-touch adsorption unit according to another embodiment of the present invention will be described with reference to FIGS. 12 to 15, but the same reference numerals are given to the same components as the above-described embodiments, and repeated descriptions of the same parts will be omitted. Let's do it.

12 to 15, the one-touch adsorption unit according to another embodiment of the present invention has a flange 324 in which the head 320 of the piston member 300 protrudes along the outer circumference of the lower end of the rod 310. And an O-ring 325 fitted to the outer circumferential surface of the flange 324 so as to contact the inner circumferential surface of the accommodation space 130.

In addition, an exhaust port 330 penetrating the center of the rod 310 and the head 320 is formed in the piston member 300, and an insertion space S communicating with the exhaust port 330 inside the upper end of the rod 310. Is formed, the insertion space portion (S) is inserted into the upper valve member 600 for opening and closing the exhaust port (330).

As a result, in the one-touch type suction unit according to another embodiment of the present invention, the head 320 of the piston member 300 always maintains the state in contact with the inner circumferential surface of the accommodation space 130 by the O-ring 325. The air below the head 320 has a structure that can be discharged to the outside only through the exhaust port 330.

The upper valve member 600 is made of a rubber material, the outer circumferential surface of the upper valve member 600 has a structure that allows air flow between the inner circumferential surface of the insertion space (S). Such a structure can be achieved by making the outer circumferential surface of the upper valve member 600 to a diameter slightly smaller than the inner circumferential surface of the insertion space S, or forming grooves extending vertically on the outer circumferential surface of the upper valve member 600.

As a result, the upper valve member 600 is raised to the upper portion of the insertion space (S) as shown in Figure 13 and 14 by the pressure of the lower side of the head 320 during the initial pressure and the final pressure of the push member 400. By opening the exhaust port 330, the air below the head 320 passes through the exhaust port 330, and then is discharged to the outside through a gap between the push member 400 and the rod 310.

On the other hand, at this time, an indentation groove (not shown) may be formed at the upper end of the rod 310 to cross the male screw up and down so that air can easily escape between the push member 400 and the rod 310.

When the pressure applied to the push member 400 is released, the push member 400 and the piston member 300 are raised as the compression spring 500 which has been compressed and deformed as shown in FIG. 15 is restored. As the negative pressure is generated on the lower side of the head 320 by the rising piston member 300, the lower surface of the upper valve member 600 comes into close contact with the lower surface of the rod 310, thereby closing the exhaust port 330. The lower side of) can maintain a negative pressure.

In addition, as shown in FIG. 15, when the one-touch type adsorption unit according to another embodiment of the present invention is attached to the installation target surface 10 and the adsorption force decreases over time, the user may push the push member 400. The reduced adsorption force can be easily recovered only by the one-touch pressing operation.

And one-touch adsorption unit according to another embodiment of the present invention made of the above structure, the fixing member 200, the piston member 300, the push member 400 and the compression spring 500 is one assembly (A) In the state coupled to each other to form a), the assembly (A) is a suction member 100 by inserting the fixing member 200 and the piston member 300 into the receiving space 130 from the upper side of the suction port (100). ) May be combined.
