Specifically, FIG. 1A shows a vacuum adsorption device in a bonded state, and FIG. 1B shows a vacuum adsorption device in a decomposition state.

Referring to FIG. 1, the vacuum adsorption device 100 may include an adsorption unit 110, a main body unit 120, a rotation controller 130, and a cover 140.

The adsorption unit 110 may have a vacuum chamber formed on the bottom thereof, and may be vacuum adsorbed onto the adhered surface. Here, the vacuum chamber means a sealed space between the adhered surface and the bottom surface, and the vacuum can be generated or removed by expanding or contracting the sealed space according to the shape change of the bottom surface. To this end, the vacuum chamber (that is, the bottom region of the adsorption unit 110) may be formed of a flexible soft material to improve adhesion to the adhered surface. The rotary support shaft 111 protrudes from the upper surface of the suction unit, and at least one control shaft 112 may protrude outwardly (in the horizontal direction) of the rotary support shaft 111. The control shaft 112 is driven up and down in accordance with the rotation of the rotation control unit 130, which causes a shape change of the bottom surface, so that the vacuum chamber can generate or remove the vacuum. In the upper surface of the adsorption part 110, specifically, the rotation preventing part 113 may be formed between the rotation support shaft 111 and the upper surface. The anti-rotation part 113 is inserted into the insertion hole 121 of the main body part 120 at a cross section, but is formed to have a length in the first direction and a length of the second rectangle in a horizontal cross section, whereby the suction part 110 is formed. ) And the main body 120 may be fixed to the adherend surface independently of the rotation of the rotation control unit 130. The rotation support shaft 111, the control shaft 112, and the rotation prevention part 113 may be formed of a hard material.

Body portion 120 is coupled from the upper side of the adsorption portion 110, the rotation support shaft 111, the control shaft 112 and the anti-rotation portion 113 of the adsorption portion 110 through the insertion hole 121 In particular, the insertion hole 121 may be formed in a shape corresponding to the anti-rotation part 113. In addition, the anti-rotation protrusion 122 is protruded upward in one region of the upper surface of the main body 120 to limit the rotation radius of the support 134 of the rotation control unit 130.

The rotation controller 130 allows the control shaft 121 of the suction unit 110 to move up and down while rotating according to an external force applied from the user, and may be rotatably coupled to the upper side of the main body 120. The rotation controller 130 includes a support groove 131 for connecting the outer circumferential surface of the accommodation groove 131 and the accommodation groove 131 and the rotation controller 130 in which the rotation support shaft 111 and the control shaft 112 are accommodated on a bottom surface thereof. It may include. Through this, the rotation of the outer circumferential surface may be transmitted to the accommodation groove 131. The guide part 132 penetrates the side surface of the accommodation groove 131 but has an inclined surface so that the control shaft 112 moves up and down along the inclined surface of the guide portion 132 when the accommodation groove 131 rotates. can do.

The cover 140 may be coupled to an upper side of the rotation controller 130 to protect the internal components of the suction unit 110, the main body 120, and the rotation controller 130 from the outside. In addition, the cover 140 may be rotated by receiving an external force from the user, and may transmit it to the rotation controller 130. To this end, the guide groove recessed inward is formed in the up and down direction on the outer surface of the rotation controller 130, and the guide protrusion protruding inward is formed in the vertical direction on the inner surface of the cover 140, so that the guide protrusion is the guide groove. Is inserted into it can transmit the rotation of the cover 140 to the rotation controller 130. In addition, the cover 140 may be formed to penetrate a region of the front surface, through which the hanger 200 may be coupled to the vacuum adsorption device 100 to be utilized as a mount. However, this is just an example, and according to the embodiment, the cover 140 may be all sealed at the front.

Although each configuration of the vacuum adsorption device 100 is illustrated as an independent part in FIG. 1, this is exemplary and various configurations may be applied according to an embodiment. For example, the rotation controller 130 and the cover 140 may be integrally formed, and likewise, the main body 120 may be disassembled into a plurality of parts.

As shown, the body portion 120 may be coupled to the upper side of the adsorption portion 110. Specifically, in order to couple between the adsorption part 110 and the main body part 120, the rotation support shaft 111, the control shaft 112, and the rotation prevention part 113 of the adsorption part 110 are the main body part 120. It can be inserted into the insertion hole 121, in which one end of the insertion hole 121 is coupled to the engaging projection 114 by the engaging projection 124 formed to combine the adsorption portion 110 and the main body 120 Can be solidified.

In addition, the rotation preventing portion 113 is formed so that the length in the first direction and the length of the second rectangle in the horizontal cross section is different, the insertion hole 121 has a shape corresponding to the rotation preventing portion 113. As such, as will be described in more detail with reference to FIG. 3, when the rotation controller 130 rotates, the main body 120 may be fixedly coupled to the adsorption unit 110 without being rotated.

Although not shown, an adhesive member may be filled in a space between the bottom surface of the main body 120 and the top surface of the suction unit 110. Here, the adhesive member may be a member having adhesiveness and elasticity, and may include, for example, a gel pad such as a soft adhesive urethane or a soft adhesive silicone, but is not limited thereto. Various members having a soft adhesive performance may be applied. . As the pressure-sensitive adhesive member is filled in the space, the pressure-sensitive adhesive member absorbs the influence of the external force causing the gap or deformation between the suction unit 110 and the main body unit 120, so that the suction unit 110 and the main body unit 120 are more effective. It can be combined stably and firmly. In addition, unlike the main body 120, at least a part of the adsorption part 110 is formed in a soft form, so that the sagging or deformation of the adsorption part 110 may be caused by external force on the use, such that the adhesive member is the adsorption part. Filling between the 110 and the main body 120 can prevent such sagging and deformation. In this case, a first partition wall (not shown) may protrude downward from the bottom surface of the main body 120, and a second partition wall 115 may protrude from the upper surface of the adsorption part 110 to contact the first partition wall. have. As a result, when the adhesive member is filled outside (ie, at the edge) of the adsorption unit 110 and the main body 120, the adhesive member is formed by the first and second partition walls 115. Through the insertion hole 121 of the main body 120 can be prevented from flowing out. According to the embodiment, the adhesive member is not only filled in the space between the adsorption unit 110 and the main body 120, but also applied to the bottom surface of the adsorption unit 110 to improve the adhesion between the adsorption unit 110 and the adhered surface. You can increase it.

As shown, the rotation controller 130 may be coupled to the upper side of the main body 120.

In detail, the rotation control unit 130 may be coupled to be in contact with the outer circumference of the rotation guide unit 123 of the main body unit 120, and may rotate along the rotation guide unit 123. An accommodation groove 131 is formed in the rotation controller 130, and a support 134 is formed to connect the outer circumferential surface of the accommodation groove 131 and the rotation controller 130 to rotate the outer surface of the rotation controller 120. It can be delivered to the receiving groove 131.

In addition, the anti-rotation protrusion 122 may protrude upward from one region of the upper surface of the main body 120. That is, the rotation preventing protrusion 122 may limit the rotation radius of the support 134, thereby limiting the rotation radius of the rotation control unit 130. In particular, since the main body unit 120 is coupled to not rotate relative to the adsorption unit 110, the rotation of the rotation control unit 130 through the anti-rotation protrusion 122 without rotating in accordance with the rotation of the rotation control unit 130. It is possible to effectively limit the radius.

Meanwhile, the coupling fixing part 125 may be formed in one region of the upper surface of the main body 120. The coupling fixing part 125 may have a region formed therethrough, and the connection part 220 may be detachably coupled through the through region of the coupling fixing part 125, as will be described in more detail below. In addition, since the coupling fixing part 125 protrudes upward from the main body part 120, the rotation radius of the rotation controller 130 may be limited in the same manner as the anti-rotation protrusion 122 depending on the formation position.

When the main body 120 and the rotation controller 130 are coupled to each other, the rotation support shaft 111 and the control shaft 112 of the suction unit 110 are accommodated in the rotation control unit 130 of the rotation controller 130. ) Can be accommodated. At this time, at least a portion of the control shaft 112 may be located in the guide part 132 formed to penetrate the side of the receiving groove 131. The guide part 132 is also rotated as the rotation control part 130 rotates. At this time, the control shaft 112 moves up and down along the inclined surface formed on the guide part 132, so that the vacuum chamber of the suction part 110 is moved. The vacuum can be formed or removed.

As shown, when the adsorption unit 110, the main body 120 and the rotation control unit 130 is coupled, the rotation support shaft 111 and the control shaft 112 of the adsorption unit 110 is the rotation control unit 130 It can be accommodated in the receiving groove 131. In this case, since the control shaft 112 extends outward from the rotation support shaft 111, the control shaft 112 may be positioned in the guide part 132 formed through the side surface of the accommodation groove 131 of the rotation controller 130.

The guide part 132 is also rotated as the rotation control part 130 rotates. At this time, the control shaft 112 moves up and down along the inclined surface formed on the guide part 132, so that the vacuum chamber of the suction part 110 is moved. The vacuum can be formed or removed.

Specifically, when the rotation control unit 130 rotates in the clockwise direction, the guide unit 132 also rotates clockwise, and the control shaft 112 moves upward along the inclined surface of the guide unit 132. As the control shaft 112 and the rotation support shaft 111 connected thereto are moved upward, a vacuum may be formed by the vacuum chamber at the bottom of the suction unit 110.

At this time, the engaging groove 133 is formed on the upper side of the inclined surface of the guide portion 132, the control shaft 112 is raised in accordance with the rotation of the guide portion 132, it can be accommodated in the engaging groove 133. That is, since the locking groove 133 is formed to be recessed below the inclined surface of the adjacent guide portion 132, the control shaft 112 is stably received in the locking groove 133, the rising position of the control shaft 112 And it can be maintained through the vacuum of the vacuum chamber of the adsorption unit 110 through this.

On the contrary, when the rotation control unit 130 rotates counterclockwise, the guide unit 132 also rotates counterclockwise, and the control shaft 112 moves downward along the inclined surface of the guide unit 132. As the control shaft 112 and the rotary support shaft 111 connected thereto are moved downward, the vacuum may be reduced or eliminated by the vacuum chamber at the bottom of the suction unit 110.

Since the guide part 132 is formed to penetrate only a portion of the side surface of the receiving groove 131, the vertical movement range of the control shaft 112 may be limited. That is, when the control shaft 112 moves along the inclined surface of the guide portion 132 as the guide portion 132 rotates and contacts the inner wall of the guide portion 132, the control shaft 112 does not exist because the inclined surface does not exist. ) Will no longer be able to move up and down. Furthermore, since the control shaft 112 cannot rotate as part of the adsorption part 110 fixedly coupled to the adhered surface, the rotation of the rotation controller 130 is also limited.

In this case, the cover 140 may be formed to penetrate one region so that at least a portion (eg, the coupling fixing part 125, etc.) of the hook 200 may be inserted into the cover 140.

In addition, since the mounting fixing part 210 is not accommodated inside the cover 140, the mounting fixing part 210 and the connection part 220 can be easily attached or detached, and the entire hooking mouth 200 is vacuum-adsorbed device 100.
