Description

[Detailed description of the invention] This invention is an outlet device for supplying therapeutic gas to patients.More specifically, the outlet body is installed by effectively utilizing the upper space of a hospital room, and a hose with an outlet valve is connected to a motor. Therefore, the present invention relates to an electric reel type outlet device that is inserted and removed from the ceiling surface.

In the conventional electric reel-type outlet device described above, a remote switch is used to insert and remove the hose with an outlet valve from the ceiling surface, but at this time, the limit for pulling out the hose is indicated by wrapping red, yellow, etc. tape. . However, with such visual means, there is a delay in opening the switch, which often causes the hose to come out too much, causing problems such as overloading the motor and wear and tear of the hose due to the guide pulley idling. was.

As a result of studies in view of the above-mentioned drawbacks of the conventional device, the present invention is designed to electrically stop winding the hose appropriately and automatically stop the hose when it is pulled out to its limit length using a limit switch with an appropriate configuration. In particular, the object is to provide an electrically operated reel outlet device which allows overloading of the motor and wear and tear of the hoses to be prevented by means of a very simple mechanism.

The present invention will be described in detail below based on illustrated embodiments.

FIG. 1 is an overall view of the device of the present invention, in which an outlet main body 2 is mounted and fixed on a beam 3 of a frame on the back side of a ceiling 1 in a hospital room, etc., and an outlet valve 4 is controlled by a switch (not shown). The attached hose 5 passes through a through hole 1a in the ceiling 1 and is configured to be automatically taken in and out from the ceiling surface.

That is, as shown in FIGS. 2 and 3, the outlet main body 2 is mounted on a main body base 6 that is mounted and fixed on the beam 3, and is equipped with a rewindable reel provided with a gas introduction pipe 7. The main body 8 and the pulley 9 are rotatably supported in the same direction with an appropriate distance between their axes, and a motor 10 is mounted and fixed thereon.

A worm gear motor is used as the motor 10, and the pulley 9 is rotated in the normal and reverse directions by the motor 10.

Further, on the main body base 6, a hose outlet pipe 11 is fixed to the lower part of the pulley 9, and a pulley idler 12 is installed adjacent to the pulley 9 from above the main body base 6. It is rotatably supported on the support portion 13 via a drive tensioner 14 .

Furthermore, the proximal end of the hose 5 is wound around the body 8a of the reel main body 8 so as to be connected to a gas inlet 7a that is open and communicates with the gas inlet pipe 7, The tip side to which the outlet valve 4 is attached is hung around the pulley 9, passed between the pulley 9 and the idler 12, inserted into the hose outlet pipe 11, and then suspended from the ceiling 1. The above motor 10
The hose 5 is configured to hang down or rise from the ceiling surface by driving and rotating the pulley 9 in the forward and reverse directions.
Located on the main body base 6, the reel main body 8
A limit switch 15 for stopping the feeding of the hose 5 is provided between the pulley 9 and the pulley 9, and a limit switch 16 for stopping the rewinding of the hose 5 is provided on the hose outlet pipe 11.

Here, the hose feed stop limit switch 15 is attached with an actuator 15a that is movable up and down, and when the hose 5 is fed out a predetermined length, it is wound around the body 8a of the reel body 8. By decreasing the outer diameter, hose 5
is lowered to the position a of the broken line in FIG.
The switch 15 is electrically connected to the motor 10 and has a support provided upright from the main body base 6 in the above positional relationship with the hose 5 so that the rotation of the switch 15 is stopped and the feeding of the hose 5 is stopped. It is fixed to the plate 17.

On the other hand, the hose rewind stop limit switch 16 is provided with a switch actuator 16a, and when the hose 5 reaches the rewind limit position, the actuator 16a is set in advance to the hose 5 at the rewind limit position. The limit switch 16 is electrically connected to the motor 10 so that it is pushed up by a fixed operating plate (not shown in FIG. 3), thereby stopping the rotation of the motor 10 and stopping the hose rewinding operation. It is connected to

Further, as an actuating means for the switch actuator 16a, a member that is pushed up by the hose 5 at the rewinding limit position of the hose 5 is provided in the hose outlet pipe 11, and this member operates the switch actuator 16a. may be pushed up, and the actuating means is arbitrary.

Referring to FIG. 4, the switch 16 will be explained in more detail. A slit portion 11a is provided vertically on one side of the peripheral wall of the hose outlet pipe 11, which is erected on the main body base 6 by welding or the like, and the hose outlet A slide pipe 18 is installed inside the pipe 11 so as to be able to freely slide up and down, and a hose guide 19 made of Teflon or the like is fixed to the lower end of the slide pipe 18, and is screwed and fixed to the upper end of the hose outlet pipe 11. A spring 21 is interposed between the cap 20 and the slide pipe 18 to bias the slide pipe 18 and the hose guide 19 in a downward direction, and the switch actuator 16a is inserted into the hose outlet pipe 11 from the slit portion 11a. It is formed by setting its tip in an inserted state.

In this case, a decorative cover 22 or the like is attached to a predetermined position of the hose 5 so that the decorative cover 22 pushes up the hose guide 19.

Thus, when the hose 5 approaches the desired unwinding end when the hose 5 is unwinding, the decorative cover 22 closes the hose guide 19 and the slide pipe 18.
is the spring 2 as shown by the two-dot broken line in Fig. 4.
At this time, the slide tube 18 pushes up the switch actuator 16a, which opens the switch 16 and cuts off the power to the motor 10, so the motor 10 stops and the hose 5 will stop rewinding.

Further, in the above means, it goes without saying that the slide pipe 18 and the hose guide 19 may be formed integrally.

As explained above, according to the electric reel type outlet device according to the present invention, the outlet body 2 is fixedly installed behind the ceiling 1, and the hose 5 with an outlet valve is moved up and down from the ceiling surface by the motor 10. In the main body base 6 of the outlet main body 2, a gas introduction pipe 7 is provided.
, a reel body 8 with a hose 5 wound thereon, a pulley 9, and a motor 10 for driving the pulley are attached, and a hose outlet pipe 11 is fixed to the lower part of the pulley 9, A limit switch 15 for stopping the hose feedout is provided between the reel body 8 and the pulley 9, and a limit switch 16 for stopping the hose rewinding is provided on the hose outlet pipe 11, so that the hose 5 can be stretched to a desired length. When the hose 5 is fed out, the switch 15 is actuated on the hose 5, and when the hose 5 is rewound to a desired height, the switch 16 is actuated on the hose 5, whereby the motor 10 is The energization is cut off, thereby stopping the rotation of the pulley 9, and the hose 5 can be automatically stopped at a predetermined feeding limit and rewinding limit, thereby,
Since the pulley etc. will not idle when the hose is raised or lowered, it will not overload the motor 10,
The drawback of the conventional device, such as the hose 5 being worn out, can be eliminated.
