Description

Detailed Description of the Invention [Field of Application of the Invention] The present invention relates to harmful substances, reactions that produce harmful substances, equipment for handling these substances, and special atmospheres such as reducing or oxidizing atmospheres, dry or humid atmospheres, etc. The present invention relates to a separation plug suitable for accommodating necessary equipment and separating two or more airtight boxes without opening them.

[Background of the invention]

The conventional separation plug for airtight boxes is disclosed in Japanese Patent Application Laid-Open No. 59-1254.
As described in No. 93, this device connects a sealed container and an airtight box and then opens and closes the lid of the sealed container without opening it to the atmosphere. These are opening/closing devices related to sealed containers and airtight boxes, and indicate boxes connected in two stages.
There was a problem in that the method of keeping the connection part airtight was difficult due to the size, and it was easy to separate the connection part and release it to the atmosphere.

[Purpose of the invention]

It is an object of the present invention to separate a plurality of airtight boxes that house devices that require atmospheric sealing and airtightness without exposing them to the atmosphere, or to provide separation so that airtight boxes can be connected in the future. To provide a separation stopper characterized in that the stopper is closed while maintaining airtightness before separation and is detachable using a handle.

[Summary of the invention]

The present invention is a separation plug that can be attached to a connecting portion of airtight boxes to be separated, and can separate the airtight boxes while maintaining their airtightness.

This separation plug is characterized in that the airtightness between the two discs is maintained before separation, and the atmosphere inside the airtight box is not released to the atmosphere even after separation. Separation and connection can be made freely using the handle inside the airtight box, and if it is provided at the opening of the airtight box to be connected in the future, it can also be used for airtightness.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG. 1st
The figure shows the isolation plug installed in the glove box. An upper glove box 1 and a lower glove box 2 are connected by a connecting short pipe 3 having upper and lower flanges. If you want to separate the upper and lower glove pockets, remove the lower glove box 2 and
1. When installing the separation plug at part A of the lower flange of the short connecting pipe 3, it is suspended from the upper part using the hanging fitting 4, and the seal gasket 5 attached to the separating plug is tightly attached to the lower flange surface of the short connecting pipe 3. set. The set state at this time is shown in FIG. Next, in order to press the seal gasket 5 so that it does not float up, the upper lever 6 is extended to the lower surface of the flange of the upper glove box 1. This extension is carried out by rotating the upper handle 7 and pulling up the upper boss 9 using a screw on the upper shaft 8 which is integrated with the upper handle 7. The upper glove box 1 and connecting short pipe 3 are now kept airtight. The lower glove box 2 is made airtight by rotating the lower handle 10 to separate the internal connection of the separation plug, and at the same time, by rotating the lower handle 10, the lower boss 12 is secured by a screw on the lower shaft 11 that is integrated with the lower handle 10.
, and press the lower lever 13 to keep the lower glove box 2 airtight.

As you can see from the above operations, it is easy to handle because it can be transported as a unit when installed. In addition, the operation for maintaining airtightness is easy because it can be performed by operating one handle each on the upper and lower sides.

〔Effect of the invention〕

According to the present invention, there is a first-order effect.

(1) Being an integrated type, it is easy to transport and operate.

Work time for separation and connection can be shortened.

(2) Can be operated with one handle each on the top and bottom.

(3) The airtight boxes can be separated while maintaining their airtightness.

(4) The atmosphere inside the airtight box can be separated without being released to the atmosphere.

(5) It can be attached to an opening that will be connected in the future and can be connected while maintaining airtightness.
