DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an example of the overall configuration of an operation hole device to which the present invention is applied, and FIGS. 2 and 3 show a detailed structure of a part thereof.
The operation hole device is provided in a partition portion 300 that partitions the exterior 100 and the interior 200. The external 100 is, for example, a factory where an operation-type environmental test apparatus is placed, and the internal 200 has environmental conditions such as low temperature and low humidity that are different from those of the outside. It is a test room of environmental test equipment that can be put. The partition portion 300 corresponds to a door or the like of an environmental test apparatus, and is usually configured as glass or with a glass window.
[0008]
The operation hole device is provided in such a partition portion 300 as an opening 1 for enabling operation of a sample or the like, and as an example of a sheet-like partition member attached to the opening 1 via a frame 2 in this example. A film 3 made of a flexible vinyl sheet or the like having transparency and a certain degree of heat resistance, a slider 4 as a moving member movably attached to the frame 2 in the opening 1 in this example, and between this and the film 3 A cylinder 6 as a sealing member for sealing the rubber, a slit 5 made of rubber, and the like.
[0009]
The opening 1 is formed to have a width for enabling manipulation of an internal sample and the like and a height for mounting the slider 4. The frame 2 is provided with grooves 21 and 22 for mounting the membrane 3 and the slider 4. If the frame 2 is provided in this manner and a film or slider is attached to the frame 2, the operation hole device can be unitized and can be easily attached to an environmental test device or the like. However, it is also possible to directly provide a structural portion corresponding to the groove or the like of the frame 2 in the environmental test apparatus or the like.
[0010]
The film 3 is divided as an upper film 31 and a lower film 32 by a mating portion 33. The mating surface of the mating portion 33 is a zipper in which double rows of protrusions and grooves are formed vertically, and a chuck portion 34 is provided as a coupling member for coupling the upper and lower mating portions 33. The upper and lower ends 31a and 32a of the upper and lower films 31 and 32 (see particularly FIG. 3) are fitted into the groove 21 of the frame 2 with a gap so as to be slidable in the vertical direction. The left and right end portions of the film 3 are fixed to both ends of the frame 2 by an appropriate method such as adhesion.
[0011]
The slider 4 includes a hole 41 through which a human hand can pass so as to face the mating portion 33 of the film 3. In this example, the cylinder 6 as a cylindrical body is extended so as to pass through the hole 41 integrally with the hole 41 so as to pass through the fitting portion 33 toward the inside 200 side. The chuck portion 34 is attached to attachment seats 61 fixed on both sides of the cylinder 6. As described above, in this example, the chuck portion 34 is attached to the slider 4 via the cylinder 6. However, if the cylinder 6 is not provided, the chuck portion 34 is attached to the slider 4 directly or via an appropriate mounting seat. It may be. The upper and lower ends 4a and 4b of the slider 4 are fitted into the groove 22 of the frame 2 so as to be slidable in the left-right direction.
[0012]
At least one set of chuck portions 34 is provided as an operation hole device, but since two sets of sliders 4 are provided in this example, two sets of chuck portions 34 are provided, one set for each slider. One set of chuck portions 34 can connect or separate the mating portions 33, and the traveling directions at that time are the respective ones constituting one set and are opposite to each other. That is, if the right and left chuck portions 34 in FIG. 2 are 34-1 and 34-2, when they proceed in the direction of arrow A, 34-1 opens the mating portion, 34-2 closes the mating portion, and arrow B The opposite is true when traveling in the direction. As a result, the mating portion opens between the chuck portions 34-1 and 34-2 and therefore between the cylinders 6 and closes outside thereof, and the membrane mating portion 33 is opened and closed as necessary to be sealed.
[0013]
The inlet portion of the cylinder 6 is sealed by the slit 5 provided in the hole 41, and the mounting seats 61 of the chuck portion 34 are mounted on the both outer surfaces on the inner side of the cylinder 6, so that the films 31, 32 are formed as described above. And the cylinder 6 are almost sealed. Accordingly, the inner and outer surfaces are temporarily sealed by these structural portions. In this example, the side cover 7 made of a flexible material is brought into contact with the upper and lower films 31 and 32 at the left and right end portions of the slider 4. Installation and further improved sealing performance. In this example, the cylinder 6 has a cylindrical shape. However, for example, an elliptical shape such as an ellipse is formed so that the both sides of the cylinder 6 and the mating portion 33 of the film 3 can be easily along. It is also possible to improve the sealing performance and to make the movement of the chuck portion 34 smoother.
[0014]
With the configuration as described above, the operation hole device is used as follows.
In an environmental test apparatus or the like, a refrigerator, a heater, a humidifier, a circulation blower, or the like including an evaporator (not shown) provided as necessary is operated, and the inside 200 is adjusted to low temperature and low humidity conditions, for example. When operating the sample after the sample to be tested such as an electronic component is placed inside, the operator pushes the slit 5 through the hole 41 of the slider 4 and puts the hand into the cylinder 6. In this state, only a slight gap is inevitably formed between the slit 5 and the hand or arm, and the air conduction between the inside and outside is almost cut off, and the sample is operated without disturbing the internal environment. Can do.
[0015]
When adjusting the position of the hole 41 in order to operate other parts of the sample or other samples, or to make it easy for the operator to operate, the hand or arm placed inside is simply left and right. Just move to where you want to go. That is, when the hand or arm is moved, the slider 4 moves through the cylinder 6 and the hole 41, and accordingly, the chuck portion 34 provided on the side end of the cylinder 6 moves, and the direction of the destination automatically is moved. It is possible to open the mating portion 33 and close the mating portion after progress. As a result, when the slider 4 moves, the mating portion 33 always opens and closes in response to the movement, enabling the cylinder 6 to move and automatically sealing the outside of the cylinder. At this time, the side cover 7 also seals between the slider 4 and the film 3 to improve the sealing performance.
[0016]
FIG. 5 shows another example of the operation hole device.
In the apparatus of the present example, the slider 3 is disposed on the inner 200 side with the film 3 facing the outer 100 side, and the chuck portion 34 is directly attached to the slider 4. Side covers 7 are attached to both ends of the slider 4 as essential seal members. The cylinder 6 is provided as necessary as indicated by a two-dot chain line. In the operation hole device of this example, when the hand is put in the hole 41 and moved to the left and right, the slider 4 moves to the left and right through the edge, the chuck portion 34 attached thereto moves, and the tip of the mating portion 33 The sides are separated and opened, and the rear side is joined and closed. Even in the apparatus of this example, the operation is easy and the airtightness between the inside and outside is maintained. In this case, between the slider 4 and the film 3, the front side is sealed with the slit 5 and the left and right side faces are sealed with the side cover 7.
[0017]
In the above, an example in which two sliders 4 are provided in the horizontal direction for both hands has been shown, but if necessary depending on the device or facility to be operated, the positions of the sliders 4 and the holes can be tilted or moved up and down. It can also be arranged in the direction. Such a device is also possible if only one slider and hole are required depending on the sample to be handled. Furthermore, although the example which couple | bonds the mating part of the film | membrane 3 with the zipper was shown above, you may use the fastener of the structure which couple | bonds each film | membrane 31 and 32 with a butt | matching surface.
