Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 7, a one-touch type adsorption unit according to an embodiment of the present invention mainly includes an adsorption device 100, a fixing member 200, a piston member 300, a push member 400 And a compression spring 500.

The adsorption device 100 is

An adsorption plate 110 attached to the installation target surface 10 (e.g., a glass surface, a tile surface, or the like);

A post 120 protruding upward from the center of the attracting plate 110; And

And a receiving space 130 formed upwardly inside the post 120.

The suction plate 110 is formed in a circular plate shape with a center slightly protruding upward and includes an inner stiffener 111 having elasticity and formed integrally with the post 120 and a skin 111 surrounding the stiffener 111 (112).

The stiffener 111 is made of a synthetic resin material such as polycarbonate, which is excellent in elasticity, and has a convex shape at the center. The post 120 is elastically deformed in a flat state by being pressed toward the mounting surface 10 side.

The stiffener 111 may be in the shape of a circular plate if necessary, or may have a structure such as a plurality of spokes arranged radially with respect to the center of the post 120.

The skin 112 is made of an elastomer material such as silicone rubber or urethane rubber and is formed so as to surround both the lower surface and the lower surface and the upper surface of the stiffener 111.

As a result, when the stiffener 111 is pressed and elastically deformed toward the installation target surface 10, the skin 112 comes into close contact with the installation target surface 10 to block the air flow. In this state, a negative pressure is generated between the skin 112 and the mounting surface 10 due to the elastic restoring force of the stiffener 111, so that the suction port 100 is firmly fixed to the mounting surface 10 .

The post 120 is cylindrical and protrudes upward from the center of the attracting plate 110.

The accommodation space 130 is formed to be open upward by the hollow of the post 120 and the lower portion of the accommodation space is formed to be able to communicate with the lower side of the attraction plate 110.

As shown in the figure, the inner circumferential surface of the accommodation space 130 is formed with a latching groove 140 through which the latching protrusion 220 of the fixing member 200 to be described later enters. The latching groove 140 may be formed in such a manner that the inner wall of the accommodation space 130 is recessed at a predetermined interval or the post 120 is laterally penetrated. It is preferable that at least two of the latching grooves 140 are formed along the circumference of the accommodation space part 130.

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

An insertion hole 210 through which a rod 310 of a piston member 300 to be described later is inserted is formed at the center of the fixing member 200.

A locking protrusion 220 is formed on the outer circumferential surface of the fixing member 200 to enter the locking groove 140 of the suction port 100 when the fixing member 200 and the suction port 100 are coupled.

In order that the fixing member 200 can be easily inserted into the accommodating space 130, the engaging protrusion 220 is formed in a wedge shape having a lower thickness and an upper thickness.

For the same purpose, the fixing member 200 has a structure in which the portions located on 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 part 130, the part where the latching protrusion 220 is formed is elastically deformed inward, so that it can be easily inserted.

At the upper end of the fixing member 200, a locking flange 230 protruding along the outer circumferential surface is formed. The engaging flange 230 is in contact with the upper surface of the post 120 in a state in which the engaging protrusion 220 enters the engaging groove 140 and thus the fixing member 200 inserted into the upper portion of the receiving space 130, So that it is not inserted further into the lower portion of the accommodation space portion 130.

As described above, in the embodiment of the present invention, the fixing member 200 and the suction port 100 are coupled to each other by the engagement protrusion 220 and the engagement recess 140.

In the present invention, the fixing member 200 and the adsorption orifice 100 are arranged such that the fixing member 200 is in contact with the adsorption orifice 100, And can be coupled to each other in various structures within a range of being inserted and fixed from the upper side of the receiving space part 130 to the receiving space part 130.

For example, a male screw is formed on the outer circumferential surface of the fixing member 200, and a female screw is formed on the inner circumferential surface of the post 120 of the suction port 100, so that the fixing member 200 and the suction port 100 are screw- It can be employed.

The piston member (300)

A rod 310 inserted into the insertion hole 210 of the fixing member 200 so as to be vertically slidable; And

And a head 320 formed at a lower end of the rod 310 and in contact with a lower inner circumferential surface of the accommodating space 130.

The rod 310 is formed in a circular rod shape and has a male thread for engagement with the push member 400 at its upper end.

The head 320 has a cross-sectional area expanded along the outer peripheral surface of the lower end of the rod 310,

A lower flange 321 and an upper flange 322 protruding from the lower end of the rod 310 around the outer circumferential surface and spaced apart from each other; And

And a packing 323 coupled to surround the lower flange 321.

The packing 323 includes a bottom portion 323a surrounding a bottom surface of the lower flange 321 and a side wall portion 323b protruding upward along the periphery of the bottom portion 323a and surrounding the outer peripheral surface of the lower flange 321, An engaging portion 323c protruding from the upper end of the side wall portion 323b along the inner circumferential surface to enter between the lower flange 321 and the upper flange 322, And a raised portion 323d which is formed so as to project upwardly in contact with the inner circumferential surface of the portion 130.

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

Accordingly, as shown in FIG. 4, the protrusion 323d contacts the inner circumferential surface of the accommodation space 130 to block the air flow between the upper and lower sides of the head 320, When the member 300 is lowered, the upper flange 322 presses the upper surface of the latching portion 323c to deform the side wall portion 323b inwardly as shown in FIGS. 5 and 6, 323d are spaced apart from the inner circumferential surface of the housing space part 130 so that the air above and below the head 320 can be communicated with each other. The lower flange 321 lifts the lower surface of the latching portion 323c and the side wall portion 323b is deformed outwardly so that the protrusion 323d is pressed against the inner peripheral surface of the receiving space portion 130, So that the sealing force between the upper side and the lower side of the head 320 is further increased.

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

The push member 400 descends with the piston member 300 and comes into contact with the upper surface of the post 120 when the piston member 300 is lowered in the receiving space portion 130 for a certain period.

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

As shown in FIG. 3, the one-touch type suction unit according to the embodiment of the present invention having the above-described structure includes a fixing member 200, a piston member 300, a push member 400, The assembly A is moved from the upper side of the suction port 100 to the accommodation space 130 in a state where the assembly member 200 and the piston member 300 are coupled to each other so as to form one assembly A. And can be coupled to the adsorption mouth 100 by being inserted.

Accordingly, the components can be assembled in a state where the protective film is attached to the lower surface of the attracting plate 110. Accordingly, contamination or damage of the attracting plate can be prevented in the assembling process, each component can be easily assembled, The assembling operation is modularized, so that the productivity can be improved.

The assembly A is inserted into the accommodation space 130 from the upper side of the suction port 100 and is coupled to the suction port 100 so that the structure of the lower side of the suction port 100 can be changed freely, The adsorption performance can be improved by providing a structure such as a partition wall 150 and a lower valve member 700 at the center of the adsorption plate 110 as shown in FIGS. 8 'to 11'.

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

First, as shown in FIG. 4, the pushing member 400 is pressed (hereinafter, referred to as "the pushing member 400") so as to be in contact with the upper surface of the post 120 in a state in which the lower surface of the attracting plate 110 is disposed to face the installation target surface 10, The pushing member 400 and the piston member 300 are lowered while the compression spring 500 is compressed and deformed as shown in FIG. 5, The air that has been in the lower side moves between the packing 323 and the inner peripheral surface of the accommodation space part 130 and moves to the upper side of the head 320.

When the push member 400 is further pressed (hereinafter referred to as "final press") so that the post 120 in contact with the push member 400 is lowered, the suction plate 110, as shown in FIG. 6, Is elastically deformed in a flat shape and is brought into close contact with the installation target surface (10). At this time, the air that has caught between the attraction plate 110 and the installation target surface 10 passes through the head 320 and then passes through the clearance between the post 120 and the fixing member 200 and between the fixing member 200 and the rod 310 through the gap.

Thereafter, when the pressure applied to the push member 400 is released, the pushing member 400 and the piston member 300 are raised as the compression spring 500, which has been compressively deformed, is restored as shown in FIG. 7 At this time, as the sidewall portion 323b of the packing 323 is deformed outward, the air flow on the upper side and the lower side of the head 320 is blocked.

In this state, a negative pressure is generated between the suction plate 110 and the mounting surface 10 due to the elastic restoring force of the suction plate 110, and the suction plate 110 is installed The negative pressure between the target surface 10 can be maintained.

When the adsorption force of the adsorption unit is lowered, the user can easily recover the adsorption force deteriorated only by pushing the push member 400 one-touch.

As shown in FIGS. 8 to 11, the one-touch type adsorption unit according to the embodiment of the present invention includes:

A partition 150 formed at the center of the absorption plate 110 and partitioning the accommodation space 130 and the lower side of the absorption plate 110;

A vent hole 160 formed at the center of the partition 150; And

And a lower valve member 700 formed on the upper surface of the partition 150 to open and close the vent hole 160.

The partition 150 is formed by extending the stiffener 111 to the inside of the post 120 and the skin 112 may be covered with the partition 150 as necessary.

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

Accordingly, the lower valve member 700 is configured such that the air pressure between the head 320 and the partition 150 is increased during the initial pressing of the push member 400, Thereby maintaining the closed state. At this time, the air between the head 320 and the partition wall 150 passes through the space between the inner peripheral surface of the accommodation space part 130 and the side wall part 323b by the side wall part 323b of the packing 323 being deformed inward, (320).

As shown in FIG. 10, the lower valve member 700 keeps the vent hole 160 closed even when the push member 400 is finally pressurized. At this time, the sucker plate 110, The air between the adsorption plate 110 and the adsorption plate 110 is elastically deformed, and at the same time, the adsorption plate 110 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 lifted as the compression spring 500, which has been compressively deformed as shown in FIG. 11, is restored The side walls 323b of the packing 323 are deformed outwardly so that the air flow on the upper side and the lower side of the head 320 is blocked and a compression spring 500 is inserted between the lower side of the head 320 and the partition 150 A negative pressure is generated.

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 150 The air between the suction plate 110 and the installation target surface 10 can escape to the space between the head 320 and the partition wall 150 and the air pressure between the suction plate 110 and the installation surface 10 can be transmitted to the head The air pressure between the suction plate 110 and the installation target surface 10 is kept constant by closing the vent hole 160 when the air pressure between the suction plate 110 and the partition wall 150 is approximately equal to or lower than the air pressure between the suction plate 110 and the partition wall 150. [

As a result, according to the above structure, the negative pressure on the lower side of the adsorption plate 110 can be more stably maintained by the partition 150 and the lower valve member 700, and the pushing member 400 is repeatedly pressurized, By further discharging it, the adsorption force can be further increased.

Hereinafter, a one-touch type adsorption unit according to another embodiment of the present invention will be described with reference to FIGS. 12 to 15, and the same constituent elements as those of the previously described embodiment are denoted by the same reference numerals, Repeated descriptions will be omitted.

As shown in FIGS. 12 'to 15', the one-touch type adsorption unit according to another embodiment of the present invention includes:

The head 320 of the piston member 300 is fixed to the lower end of the rod 310 by a flange 324 protruding along the outer circumferential surface of the rod 310 and an O- (O-ring) 325 as shown in FIG.

The piston member 300 is provided with a rod 310 and an exhaust port 330 passing through the center of the head 320. An insertion space S communicating with the exhaust port 330 is formed inside the upper end of the rod 310, And an upper valve member 600 for opening and closing the exhaust port 330 is inserted into the insertion space S.

As a result, the one-touch type absorption unit according to another embodiment of the present invention always keeps the head 320 of the piston member 300 in contact with the inner circumferential surface of the accommodation space portion 130 by the O-ring 325, And the air below the head 320 can be discharged to the outside only through the discharge port 330. [

The upper valve member 600 is made of a rubber material and the outer circumferential surface of the upper valve member 600 has a structure capable of air circulation between the inner circumferential surface of the insertion space S and the inner circumferential surface. Such a structure can be achieved by manufacturing the outer circumferential surface of the upper valve member 600 with a diameter slightly smaller than the inner circumferential surface of the insertion space S or by forming grooves extending vertically on the outer circumferential surface of the upper valve member 600. [

As a result, the upper valve member 600 is inserted into the insertion space S as shown in FIGS. 13 and 14 by the initial pressure of the push member 400 and the pressure of the head 320 at the time of final pressing, The air in the lower part of the head 320 passes through the exhaust port 330 and is discharged to the outside through the gap between the push member 400 and the rod 310 by opening the exhaust port 330 .

At this time, an annular groove (not shown) may be formed on the upper end of the rod 310 so as to allow the air to escape easily 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 lifted as the compression spring 500, which has been compressively deformed, is restored as shown in FIG. 15 The lower surface of the upper valve member 600 is brought into close contact with the lower surface of the rod 310 to close the vent hole 330 as a negative pressure is generated below the head 320 by the piston member 300 rising at this time, So that the lower side of the valve body 320 can maintain the negative pressure.
