Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a blind plate device for expanding glove boxes that handle substances harmful to the human body or substances that should not be contaminated with airborne impurities. .

[Prior art]

A glove box has a glove for operating the inside from the outside while keeping the inside and outside separated, but in the process of using the glove box, it may become necessary to connect and add more glove boxes. In this case, conventionally, the interior of the glove box during use is thoroughly cleaned before being processed for expansion.

However, the above-mentioned conventional methods have problems in that the human body is exposed to danger, a long period of time is required, and the cost is enormous. Furthermore, if there are complex devices inside the glove box, it is impossible to clean them.
There was also the problem that we had to give up on expanding the facility.

[Purpose of the invention]

Therefore, the present invention solves the above-mentioned conventional problems,
The object of the present invention is to provide a blind plate device for expanding a glove box which has a simple structure, good workability, and is inexpensive.

[Structure of the invention]

That is, the glove box expansion blind plate device of the present invention has a connection port for glove box expansion.
A flange having a protrusion protruding from the inner periphery of the connection port may be provided, a blind plate having a shape capable of coming into contact with the protrusion of the flange, and the blind plate may be fixed to the protrusion via a fastener. It is constructed by providing a blind plate holding frame.

〔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 blind plate device for expanding a glove box in an embodiment of the present invention. It is provided at the end of a glove box 1 as shown in the overall plan view of FIG.

Next, a flange 3 is integrally provided on the connection port 2 for expansion of this glove box 1. In this embodiment, since the glove box 1 has a square cross section, the flange 3 has a square ring shape. doing.

Therefore, the flange 3 is formed with a protrusion 3A that slightly protrudes from the inner circumference of the connection port 2.
On the other hand, there is a blind plate 4 having a shape that allows it to come into contact with the protrusion 3A of the flange 3 from the outside of the connection port 2, that is, from the side of the additional glove box 1A shown by the two-dot chain line in FIG. Bolts and nuts 5, which are fasteners, are provided protruding from the glove box 1 side of 4.

Also, the blind plate 4 is connected via this bolt and nut 5.
A blind plate holding frame 6 is provided which can be fixed to the protrusion 3A of the flange 3.

[Effect]

In the blind plate device for expansion of the glove box 1 of the present invention having the above configuration, the packing 7 is interposed on the protrusion 3A of the flange 3 of the connection port 2 at the end of the existing glove box 1 for expansion. The blind plate 4 can be fixed with a blind plate holding frame 6 through bolts and nuts 5.

Therefore, when connecting the additional glove box 1A, first connect the glove box 1A to the end of the glove box 1 with the bolt 8, then remove the bolt and nut 5, disassemble the blind plate holding frame 6, and then , simply fold down the blind plate 4 and carry it out from a large port (not shown) provided on the glove box 1A side. The glove box 1 and the additional glove box 1A are connected to communicate internally.

〔Effect of the invention〕

Therefore, the blind plate device for glove box expansion according to the present invention has a structure in which the blind plate is sandwiched between the blind plate holding frame against the protruding part of the flange, and has the advantage that the structure is simple and inexpensive, and the workability is good. There is.
