Next, the operation of the suction device 1 of the present embodiment will be described by taking a case where the communication unit 92 is temporarily fixed to the main body 91 of the smart meter as an example. The communication unit 92 of a general smart meter has a rectangular parallelepiped shape with a side of 12 to 13 cm and a thickness of about 2 to 3 cm, and the suction device 1 used for this has a size that fits in the palm of a total length of about 15 cm. is there. The application and size of the adsorption device 1 of the present embodiment are not limited to this.

When the suction device 1 is used, the check cap 21 is screwed into the nozzle 15 of the suction unit 11 and the check cap 21 is tightened until the first seal member 26 and the tip surface of the nozzle 15 are in an airtight state. In this state, one suction cup 12 of the suction device 1 is brought into close contact with the main body 91, and the other suction cup 13 is brought into close contact with the communication unit 92 (see FIG. 5).

With the suction cups 12 and 13 in close contact with the main body 91 and the communication unit 92, the intake unit 41 is put on the check cap 21, and the trigger portion 52 is pulled while pressing the tip surface of the cylinder 42 against the second seal member 27 ( Push in) (see FIG. 6).

When the trigger portion 52 is pulled, the piston portion 51 retracts and the volume inside the cylinder 42 increases, and the air inside the suction cups 12 and 13 (and the suction unit 11, the check cap 21) is sucked into the cylinder 42 and the suction cup The pressure inside 12 and 13 becomes negative, and the suction cups 12 and 13 are attracted to the main body 91 and the communication unit 92 of the smart meter (see FIG. 3). After intake, even if outside air enters through the gap between the check cap 21 and the intake unit 41, the check valve 31 of the check cap 21 prevents the pressure recovery in the suction cups 12 and 13.

As a result, the communication unit 92 of the smart meter is fixed to the main body 91. At this time, the intake unit 41 is attracted to the check cap 21, but may be removed from the check cap 21.

When releasing the fixation between the main body 91 of the smart meter and the communication unit 92, the handle portion 47 of the cylinder 42 is operated while the housing 44 of the intake unit 41 is fixed (grasped) to rotate the cylinder 42 counterclockwise. Let me. When the cylinder 42 rotates, the protrusions 24 and 45 mesh with each other, so that the check cap 21 rotates counterclockwise, forming a gap between the first seal member 26 and the tip surface of the nozzle 15, and air flows in. Then, the pressure inside the suction cups 12 and 13 is restored and the suction is released (see FIG. 7). The rotation direction of the cylinder 42 at the time of recompression may be appropriately changed depending on whether the male screw 18 and the female screw 23 are right-handed or left-handed.

As described above, according to the suction device 1 of the present embodiment, at the time of suction, suction can be performed only by pushing the trigger portion 52 of the intake unit 41, and at the time of attachment / detachment, attachment / detachment can be performed only by twisting the handle portion 47 of the intake unit 41. Since it is possible, it can be easily attached to and detached from the object to be adsorbed. Further, since the cylinder 42 that is rotated by the operation of the trigger portion 52 and the handle portion 47 is guided by the housing 44, the operation is easy. In this way, the attachment / detachment operation can be performed with one action, and no skill is required for the operation, so that anyone can easily attach / detach the object to be adsorbed in a short working time.

Further, according to the suction device 1 of the present embodiment, after the suction by the suction unit 41, the suction unit 41 is sucked to the check cap 21, so that the suction unit 41 is sucked as it is when the suction cups 12 and 13 suck the object to be adsorbed. I can let you. As a result, it is possible to reduce the labor and space for collecting the intake unit 41 after adsorption with the object to be adsorbed.

Further, according to the adsorption device 1 of the present embodiment, since the adsorption device 1 can be adsorbed to the object to be adsorbed without applying an excessive load, damage to the object to be adsorbed can be prevented. Moreover, since it can be used repeatedly, it is advantageous in terms of resource consumption and waste discharge as compared with the case of using tape or the like.

Further, according to the suction device 1 of the present embodiment, the check valve 31 of the check cap 21 prevents the inflow of air at the time of suction, so that it is possible to prevent a decrease in the suction force. For example, a smart meter. It is possible to prevent the communication line (not shown) that connects the main body 91 of the smart meter and the communication unit 92, which is caused by the communication unit 92 being detached from the suction device 1, from falling off or being damaged.
