Description

[Detailed explanation of the invention] [Purpose of the invention] (Industrial application field) This invention relates to constant temperature storage for precision equipment, and is used for constant temperature storage of precision equipment to store precision equipment such as various experimental equipment and medical equipment. Regarding storage.

(Conventional technology) Precision instruments such as various experimental measuring instruments, medical/physical and chemical analysis instruments, and cameras have traditionally been extremely susceptible to the surrounding environment such as temperature, humidity, and dust, and are susceptible to performance deterioration. In order to connect these devices, constant-temperature storage for precision equipment is provided to preserve and store them under certain conditions.

(Problem that the invention aims to solve) However, in conventional constant-temperature storage for precision equipment, the vibrations of the cooling device installed to store precision equipment at a constant temperature are transmitted to the precision equipment in the storage room. There were drawbacks that adversely affected the performance of the equipment.

Therefore, for example, a refrigerated case was proposed in Japanese Utility Model Application Publication No. 58-172789, and
A simple type cold storage box has been proposed in Publication No. 231375.

However, the former type of refrigerated case has a structure in which the cooling device can be pulled out laterally in order to separate the cooling device and the storage case, so the distance to pull out the cooling device is large and the work is labor-intensive. However, since the structure was bulky, it had the disadvantage of increasing costs.

In addition, the latter type of simple cold storage has a structure in which the cold storage itself is miniaturized and placed on top of the cooling device, and the cold storage can be separated and installed at the required location when needed. Because of this, it takes a lot of effort to separate the coolers, and the separation distance is also large, making it difficult to separate them easily unless they are very small.

<Technical Issues> Therefore, this invention was devised to eliminate the above-mentioned drawbacks that existed in the past.The structure is simple, the cooling device can be separated extremely easily on the spot, and the vibration of the cooling device can be reduced. To provide a constant-temperature storage for precision equipment that can preserve the precision equipment well without being affected by the stored precision equipment.

[Structure of the invention] (Means for solving the problem) Therefore, this invention is a thermostatic storage for precision equipment equipped with a cooling device, in which the main body of the storage is divided into a storage room for precision equipment and a compartment at the bottom. In addition, a cooling device installation space opened downward is provided to form a foot portion to be grounded, and the cooling device is suspended and fixed from the foot portion by bolts and nuts, and is lowered by loosening the nut. The above object has been achieved by forming the cooling device so that it can be separated from the main body of the storage by further loosening the nut while the cooling device is grounded.

(Function) Therefore, in the above-mentioned device, in a constant temperature storage for precision equipment equipped with a cooling device, the main body of the storage is divided into a storage room for precision equipment at the bottom and is opened downward. A space for installing the cooling device is provided, and a foot portion is formed to be grounded, and the cooling device is suspended and fixed from the foot portion by bolts and nuts, and the cooling device that descends by loosening the nut is grounded. The cooling device can be separated from the main body of the storage by further loosening the nuts, so when installing a constant temperature storage for precision equipment or when moving, it can be hung from the legs using bolts and nuts. After installation, the cooling device is lowered by loosening the nut, and the cooling device is separated from the main body by loosening the nut.

As a result, the vibrations of the cooling device are not transmitted to the storage main body, and vibrations are not applied to the precision instruments stored in the storage chamber of the storage main body.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

Reference numeral 1 shown in the figure is a storage main body for storing precision equipment such as experimental equipment, and includes a storage room 2 for storing precision equipment and a cooling device 3 for adjusting the temperature inside the storage room 2. It becomes.

The storage main body 1 is divided into a storage room 2 for precision equipment at its lower part and has a cooling device installation space opened downward, and has a foot portion 1a formed to be grounded, and on the bottom surface of the foot portion 1a, Four casters 8 are arranged, and a bottom plate 4 on which a cooling device 3 is placed and fixed is configured to be removable from the storage main body 1 in the cooling device installation space.

That is, as shown in the figure, the bottom plate 4 is formed separately from the foot part 1a of the storage main body 1 on which the casters 8 are arranged, and its four corners are connected to the fixing plate 5 protruding from the inner surface of the side plate of the foot part 1a. The cooling device 3 is tightened and fixed in a substantially suspended state by bolts 6 and nuts 7, and by loosening these bolts 6 and nuts 7 and pulling them upward while rotating the nuts 7, the cooling device 3 is lowered by its own weight. By further loosening the nuts 7, the bottom plate 4 is grounded, the nuts 7 are separated from the fixed plate 5, and are separated from the foot portions 1a of the storage cabinet main body 1, and are installed on the floor.

Further, on the lower surface of the bottom plate 4, a vibration absorbing material 9 made of a rubber material or the like is provided which is thicker than at least the thickness and width of the head of the bolt 6. Therefore, when the bottom plate 4 is separated from the storage main body 1 and the vibration absorbing material 9 comes into contact with the floor surface, the vibration of the cooling device 3 on the bottom plate 4 is absorbed by the vibration absorbing material 9, and the vibration is transmitted through the bolts 6. It is possible to more effectively prevent the information from being transmitted to the storage main body 1.

Further, bolts 6 provided on the fixing plate 5
If the small hole through which the screw is inserted is formed to be slightly larger than the diameter of the bolt 6, even if the vibration of the cooling device 3 is slightly transmitted to the bolt 6, the bolt 6 will not touch the fixing plate 5. , and no vibration is transmitted to the storage main body 1 at all.

Note that reference numeral 10 is a flexible pipe connected from the cooling device 3 to the storage room 2;
It is formed so that it can change in response to the movement of the vertical position.

Next we will explain its use.

First, before operating the cooling device 3, the bolts 6 and nuts 7 that fix the bottom plate 4 to the fixed plate 5 are loosened, and the nuts 7 are rotated to the upper position, as shown in FIG. As shown, the bottom plate 4 is removed from the foot portion 1a of the storage main body 1 and lowered so that the vibration absorbing material 9 provided on the lower surface of the bottom plate 4 is in contact with the floor surface. Therefore, by simply loosening the nut 7 and lifting it up, the cooling device 3 placed and fixed on the bottom plate 4 can be easily separated from the storage main body 1, and the vibrations of the cooling device 3 can be removed from the storage. This can be prevented from being transmitted to the main body 1.

When the cooling device 3 is not operated, pull up the bottom plate 4 and tighten the bolts 6 and nuts 7 to fix the plate 5.
It can be fixed to any location, and can be moved and installed at any location using casters 8.

It goes without saying that the thermostatic storage for precision equipment according to this invention is not limited to the embodiments described above.

[Effect of the invention] Accordingly, this invention provides a constant temperature storage for precision equipment equipped with a cooling device 3, in which the storage main body 1 is partitioned into a storage room 2 for precision equipment at its lower part, and a cooling chamber is opened downward. The cooling device 3 is suspended and fixed to the foot portion 1a by bolts 6 and nuts 7, and is lowered when the nuts 7 are loosened. 3 is grounded, the cooling device 3 can be separated from the storage main body 1 by further loosening the nut 7, thereby making it possible to install a constant temperature storage for precision equipment.
Alternatively, when moving, suspend and fix the cooling device 3 to the leg 1a with bolts 6 and nuts 7, and then install the cooling device 3.
is lowered by loosening the nut 7, and the cooling device is separated from the storage main body by further loosening the nut 7, so the vibration of the cooling device 3 is lowered by loosening the nut 7.
