Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an environmental testing device that has a door that opens and closes and can accommodate a sample to be connected to the outside by a connecting member, and more particularly to a technique for penetrating the connecting member.

[0002]

[Prior art]

 In the environmental test by the environmental test device, as shown in FIG. 16, a sample 100 is put in the inside 3 of the device, a thermocouple 101 is connected to this, and a cable 102 is installed in the outside 4 of the device. The test may be performed by penetrating the connection member between the inside and outside of the device, such as connecting to 103 and measuring the temperature outside. For such a purpose, in the conventional environment test apparatus, the cable hole 104 having a diameter of up to about 100 mm is usually provided at an appropriate position on the wall surface of the apparatus body. However, since the specimen is often larger than the cable hole, the specimen 100 is installed inside the equipment and the thermocouple cable 102 is connected to the recorder 103 outside the equipment in the above environmental testing equipment. The thermocouple 101 and the cable 102 were brought into the apparatus through the cable hole 104, and the thermocouple 101 was attached to the test piece 100 inside the apparatus.

However, according to such a method, the work of attaching the thermocouple has to be performed in the environment test apparatus having poor workability. In some cases, the same measurement may be performed by moving the test piece to another environmental testing device.In such a case, the attached thermocouple must be removed once, and the mounting work must be performed again in the moved device. The conventional device had a poor workability in this respect.

On the other hand, as a device for solving such a problem, there has been proposed a device in which a slit is provided in a packing of a door of an environmental test device, and a thermocouple cable is sandwiched in this portion (actual Kaihei 2- No. 101251). With this device, by opening the door, the specimen can be taken out to the outside together with the cable with the thermocouple attached. However, in such a device, the cable is forcibly pressed by a part other than the packing part such as the mating surface of the door, or the cable is pinched and the door is not closed sufficiently, resulting in poor heat insulation and sealing between the inside and outside. There was a problem of becoming. In addition, when the number of thermocouples is large and the number of cables is large, there is a problem that the cables cannot be passed only by the packing part. In addition, environmental test equipment sometimes tests large machines and equipment.In such a case, it is necessary to pass power supply, power line, water, oil, air, etc. pipes between the inside and outside of the equipment. , The above-mentioned device cannot support.

[0005]

[Problems to be solved by the device]

 It is an object of the present invention to solve the above problems in the prior art and to provide an environmental testing device with improved workability in test preparation and loading / unloading of specimens.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides an environment testing device that includes a door that opens and closes, and is capable of containing a specimen that is connected to the outside by a connecting member. It is characterized by having an opening including a part of the edge that is opened when the door is opened.

[0007]

[Action]

 The environmental test device may include a test piece connected by a connecting member to an external device such as an instrument installed outside. This connecting member is usually instrument wiring such as a temperature sensor and a pressure sensor. When the entire mechanical device is a test piece, power cables, power lines, compressed air, water, oil pipes, etc., also serve as connecting members.

According to the present invention, since the opening of the door is sized so that the connecting member as described above can penetrate therethrough, when the door is closed, the connecting member should be housed in this opening. You can Further, since the opening includes a part of the edge that is opened when the door is opened, when the door is opened, the opening is also opened. Therefore, the external device and the specimen were connected by a connecting member outside the environment test equipment, and with the door open, the specimen was placed in the equipment together with the connecting member, and the end face of the door was opened. The external device and the test piece can be connected by accommodating the connection member in the opening from the side and closing the door. When the specimen is taken out from the environment test equipment, the door can be opened and the connecting member can be pulled out from the end face of the opening, so that the connecting member and the specimen can be put together and carried out from the door. Therefore, the connecting member and the test piece can be connected to the outside with good workability, and the test piece can be put in and taken out of the environmental test device without disconnecting the connection. As a result, work efficiency is significantly improved. Also, the relocation of the specimen becomes easy. And, especially when testing mechanical devices, it may be necessary to connect many electric wires and pipes, but the present invention makes it easy to put in and take out such a specimen, and the workability is significantly improved. Improve to.

When a gap is created between the opening and the connecting member when the connecting member is penetrated through the opening, an appropriate filling is provided in this gap so that the heat insulation and airtightness of the environmental testing device are improved. Can be maintained. Also, when the sample is not connected to an external device, or when neither the sample nor the connecting member can be put in the device, it is necessary to maintain the environmental condition in the device. For this purpose, for example, a closing member made of a heat insulating or flexible material is fitted into the opening. However, it is desirable to pre-make the opening closure member for this purpose. Further, the closing member may be a device permanently installed in the opening.

【Example】

 FIG. 1 shows the structure of the door portion of the environmental testing device of the embodiment. The environment tester has doors 1 and 2 that can be opened and closed, a test piece 100 is placed in the inside 3, a thermocouple 101 is connected to this if necessary, and a recorder 103 installed in the outside 4 with a cable 102. Be combined. In the environmental test equipment, for example, a meteorological environment test in which temperature and humidity are controlled by controlling the internal temperature and humidity, and a physical environment test in which vibration, shock and acceleration are applied are performed.

The door 1 on one side is provided with an opening 5 including an end edge 1-1 thereof. The opening 5 has such a size that the connecting member 102 can penetrate therethrough, and is determined depending on the type and purpose of use of the environmental testing device, the size, the type of sample to be targeted by the user, and the like. The opening 5 needs to be closed with a suitable closing member when no connecting member is inserted therein. As a method for this, for example, heat-resistant (silicon) rubber, heat-resistant sponge, etc. may be cut to a size slightly larger than the size of the opening 5 to form a closing member, and this may be packed in the opening. However, it is desirable to prepare the closing member in advance in order to maintain the heat insulation and airtightness and keep the condition inside the environmental test device in good condition, and for the convenience of handling. For this reason, in the present embodiment, a closing device has been proposed, which is variously devised regarding the structure, the mounting method thereof and the like.

In FIG. 1, a lid 6 as a closing member is formed by attaching a bakelite plate 6b to a support structure 6a, attaching a neoprene sponge 6c thereto, and covering them with an exterior plate 6d. This lid 6 is obtained by fitting the mounting plate 6a-1 of the support structure 6a into a protruding member 7 attached to the back side of the door 1 (inside 3 of the environmental testing device) as shown in FIG. , Attached to the door 1.

FIG. 3 and FIG. 4 show a closing device with improved thermal insulation of the opening 5. In FIG. 3, the closing device is configured by providing the protruding member 8 around the opening 5 of the door 1 and providing the lid 6 with the groove 6e into which the protruding member 8 is fitted. The closing device of FIG. 4 has a structure in which the opening 5 of the door 1 is provided with the contact surface 9 and the packing portion 6f attached to the lid 6 is applied to the contact surface 9. With such a structure, the sealing property and heat insulating property of the lid 6 are improved.

5 to 8 show an example in which the lid 6 is permanently installed on the door 1 so as to be openable and closable. In this way, the work of storing and taking out the lid 6 can be saved, the lid is not lost, and the handleability is improved. FIG. 5 shows an example in which the lid 6 is attached to one surface of the door 1 by the hinge 10 so as to be openable and closable. In FIGS. 6A and 6B, a packing 6g is attached to the lid 6, and the packing 6g is applied to the contact plate 11 provided on the door 1 or the wall surface of the door 1. By doing so, the sealing property is improved. In this case, a twisting spring that is closed and may be inserted in the hinge portion. FIG. 6 (c) shows an example in which the lid 6 is attached below the opening 5 so that the lid 6 can be opened and held at an angle of about 90 ° to 120 °. By doing so, the lid 6 can be used as a guide portion for a cable or the like. FIG. 7 shows an example in which the lid 6 is attached to the upper side of the opening 5 and the packing 12 is attached to the lower side of the door 1. The packing 12 may be provided with notches 12a and holes 12b as shown in the drawing. By doing so, a cable having a thickness similar to that of the thermocouple cable can penetrate the opening 5 with the lid 6 closed. As a result, it is not necessary to block another gap between the opening 5 and the cable, which simplifies the preparation work for the environmental test. FIG. 8 shows an example in which the lid 6 is opened laterally, the packing 12 is attached to the lid 6 side, and the notch 12a and the hole 12b are similarly provided. In this case, as shown in FIG. 2B, the packing 12 hits the protruding portion 2a of the counterpart door 2 to seal the cable, but the cable passes through the hole 12b and the gap between the lid 6 and the door 2. Therefore, also in this case, the cable can be passed through with the lid 6 closed.

9 and 10, the shape of the lid is not specified, and the mounting plate 6a-1 of the support structure 6a attached to the projecting member 7 shown in FIG. 1 and the main body portion 6h of the lid 6 are separated. Here is an example. In this way, the main body portion 6h is not specified, and the user of the environmental testing device can freely determine the shape using a resin sponge or the like according to the purpose of use of the device. In FIG. 9, the main body 6h of the lid 6 has the same shape as in FIG. 1, but in FIG. 10, the notch 6h-1 or the small hole 6h-2 is provided in this. In this way, if the notches and small holes can be opened according to the purpose of use, the cable passage part can be freely processed, and the labor of closing the gap between the opening 5 and the cable with another filling can be saved. Workability is improved.

11 and 12 show another shape of the opening 5. The openings are not limited to the squares and rectangles used in the above examples, but can be any shape such as semicircles and triangles that are convenient for use. In this case, the lid 6 is also shaped accordingly. Further, the mounting position of the opening 5 in the door 1 is not limited to the mating surface between the door 1 and the door 2, but may be the surface facing the upper and lower door frames. If the openings 5 are provided at the upper and lower positions, it may be convenient to lay cables and the like in the environment testing device. Even in the case of a single door, it is possible to attach the opening having a shape including a part of the upper and lower peripheral portions as described above. Further, the present invention can be applied not only to a door opened by rotation, but also to a door opened by sliding left and right or up and down.

With the above-mentioned configuration, the environment test apparatus is handled as follows. When the specimen is not placed in the device or when the specimen is not required to be connected to the outside, the doors 1 and 2 are closed and the door 1 is closed as shown in FIG. The lid 6 is inserted into the opening. Thereby, the sealing property and the heat insulating property are maintained, and the environmental condition of the inside 1 of the environmental test device is maintained.

Next, as shown in FIG. 14, for example, when the thermocouple 101 is attached to the test piece 100 and is connected to the external recorder 103 by the electric wire 102, after connecting between them, the door 1 and the door 2 are connected. Open and bring the thermocouple 101 and the electric wire 102 to the DUT 100 into the inside 3 of the environmental testing device, and put the electric wire 102 into the opening 5 of the door 1, and as shown in FIG. Close door 2. Then, a suitable sealing material such as sponge is packed between the opening 5 and the electric wire 102. In this case, when the lid 6 as shown in FIGS. 7, 8 and 10 is used, it may not be necessary to pack the sealing material. When taking out the sample 100 to the outside, the door 2 is opened, the electric wire 102 is removed from the opening 5, and these are integrally taken out through the doors 1 and 2. As a result, the thermocouple 101 can be detached from the test piece 100 at an outer portion with good workability. In addition, it is also possible to move these devices to another environmental testing device having the same structure with the devices attached. Further, since the opening 5 is provided, even if the electric wire 102 is inserted and the door is closed, there is no problem that the packing portion is damaged or the electric wire 102 is sandwiched by the door and the sealing property is deteriorated. Furthermore, not only the instrumentation cable and the like, but also the power supply, the power cable, the hose, the pipe, and the like can be penetrated through the opening portion 5, and it is possible to cope with the specimen such as a mechanical device. Especially, in machinery, there are many cables and pipes, and the size and weight increase, so that the handling performance is greatly improved by using the environmental test device of the present invention.
