Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a glove box separation lid used at the connection part of a glove box that handles substances harmful to the human body or substances that do not want to be contaminated with airborne impurities. It is.

[Prior art]

A glove box has a glove for operating the inside from the outside while keeping the inside and outside separated, but it may be necessary to move the glove box during or after use. When multiple glove boxes are connected, it is necessary to move the glove box that needs to be moved and other glove boxes while maintaining airtightness.

However, the structure of the conventional glove box separation lid is very complicated and expensive, and there is a problem in that it takes time to separate and connect the lid.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and provide a glove box separation lid that is simple in structure, easy to work with, and inexpensive.

[Structure of the invention]

That is, the glove box separation lid of the present invention is provided with two blind plates that can be joined and separated from each other so that they can be inserted into and removed from the connection opening between the glove boxes.
It is constructed by providing a fastener that can fix each of the two plates to the respective glove box side member.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional side view of a main part of a glove box separation lid in an embodiment of the present invention, and this separation lid is shown in a plan view as shown in FIG. 2. The connection port 4 of the glove box 1 shown in the side view of FIG. 2 and the side view of FIG. In Figures 2 and 3, 5 is a glove attachment part, 6 is its panel, and 7 is a large port.

In addition, an expansion joint 10 is provided at the connection port 4 in consideration of earthquake resistance and airtightness of the installation of the connection part.

Next, this separation lid consists of two blind plates 8 and 9, which can be joined and separated from each other, and the blind plate 9 is inserted into the recess 8A provided on the side of the blind plate 8. By inserting pins 9A provided on the sides, they can be joined at predetermined positions.

In addition, these blind plates 8 and 9 can be inserted into the connection port 4 from inside the glove box 3 in Figure 2 when they are joined together as shown in Figure 1, and one blind plate This blind plate 8 is fixed to a flange 13 fixed to an expansion joint 10 via a blind plate holding frame 12 to a stud bolt 11 which is a fastener provided on the plate 8, and the other blind plate 9 is fastened. It is fixed to a member on the glove box 3 side with a bolt 14 which is an attachment.

Note that 15 in the figure is a gasket for maintaining airtightness.

[Effect]

Using the separation lid of the present invention having the above configuration,
When separating the connection port 4 between the glove box 1 and the other glove box 3 connected to it, first connect the blind plates 8 and 9 outside the glove box 3, as shown in FIG. After assembling, attach it to the connection port 4 from inside the glove box 1, fix the blind plates 8 and 9 with stud bolts 11 and bolts 14, which are fasteners, and then attach the blind plate holding frame 12.
are attached to the stud bolts 11, and the blind plate 8 and flange 13 are fixed.

Next, by removing the bolts 16 that fixed the flange 13 and the glove box 1 side via the gasket 15, and separating them with the separation bolts 17 shown by broken lines, the glove box 1 and the other glove box 3 are separated from each other by S. Separated at the separation position.

The joints of blind plates 8 and 9 are not contaminated by the atmosphere of the glove boxes, so they are connected to glove boxes 1 and 4.
Even if the glove box is separated, the contaminated surface will not be exposed outside the glove box.

On the other hand, the operation of connecting the separated glove box 3 to the glove box 1 can be performed by the reverse procedure.

〔Effect of the invention〕

Therefore, the glove box separation lid of the present invention has an extremely simple structure compared to conventional ones, has good workability, can be manufactured at low cost, and is highly safe.
