Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-vibration structure for an electronic equipment storage rack such as a storage rack for loading electronic equipment such as measuring equipment on a moving body such as a vehicle.

[0002]

2. Description of the Related Art FIG. 2 is an explanatory view of a first method for loading electronic equipment on a conventional storage rack, and FIG. 3 is an explanatory view of the same conventional second method. 2. Description of the Related Art Conventionally, in a storage rack for storing electronic equipment such as measuring equipment, as shown in FIG. 2, it is simply installed on a shelf 2 fixed to a frame 1 of the storage rack, or a band or a metal fitting 3 is arranged on the shelf 2. If the electronic device 4 for fixing the device 4 or storing the device 4 as shown in FIG. 3 is a device in which the hole 6 for mounting the storage rack is arranged on the front panel 5, the hole 6 is used to store the frame. Fixed to 1. When the storage device has a heavy mass, an L-shaped support rail 7 fixed to the frame 1 is arranged and the rail 7 supports the device 4. For moving objects such as vehicles using such a storage rack,
When the electronic device 4 is loaded, vibrations and shocks generated during movement are directly transmitted to the electronic device 4 and cause failure or damage. Therefore, in the storage rack to be loaded on the moving body, a shock absorber (shock absorber) is provided on the bottom surface or the back surface of the storage rack 8 as shown in FIG.
9 is arranged to adopt a structure in which the entire storage rack is vibration-isolated, or on the shelf 2 of the storage rack as shown in FIG.
The electronic equipment 4 is loaded on the anti-vibration base 10 having the above-mentioned arrangement, and the equipment 4 is fixed by the band and the metal fitting 3 to take anti-vibration measures.

[0003]

However, in the conventional structure shown in FIG. 4, the shock absorber 9 that supports the entire mass of the storage rack is necessary, and the shock absorber 9 that necessarily supports a large mass is required.
Has a large shape and is expensive. Further, if all the devices to be housed are not electronic devices requiring earthquake resistance, it is not preferable in terms of cost efficiency. On the other hand, in the conventional structure shown in FIG. 5, it may be installed only in the electronic device 4 that requires earthquake resistance, but the space for accommodating the device 4 for 10 minutes is reduced, and the device with the vibration isolation mechanism is used. Space for the shaking range of is also required. This is a serious disadvantage for vehicles with limited space.

[0004]

In order to solve the above-mentioned problems, the structure of the present invention has a storage rack for loading electronic equipment 4 as shown in FIG. The sponge 12A is sandwiched between the shelf 2 fixed to the frame and the base 11 and the long hole 14
Also, sponges 12B and 12C are inserted between the U-shaped device fixing bracket 13 fastened with the screw 15 and the electronic device contact surface.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows one embodiment of the structure of the present invention.
It is a perspective view showing an example. In this form, a shelf 2 fixed to a storage rack and a base 11 for loading equipment with both sides bent
A sponge 12A is sandwiched between them and adhered to the shelf 2 and the base 11. Further, the U-shaped metal fitting 13 for pressing the device 4 is bonded with sponges 12B and 12C on the upper side and both sides in contact with the device. Further, this metal fitting 13 has a long hole 14 for coupling with the base 11, and it can be adjusted in the vertical direction, and when the device 4 is removed, if the screw 15 that fastens the metal fitting 13 and the base 11 is loosened. It has a structure that allows the device to be taken out. When the shelf 2 having such a structure is installed on the storage rack, vertical and horizontal vibrations / impacts of the moving body are transmitted from the storage rack frame to the shelf 2, but the space between the shelf and the base 11 is buffered by the sponge 12A. . In addition, the left and right and upward directions are the sponges 12B and 12C of the metal fitting 13 for fixing the device.
Is further buffered, and the influence on the equipment is extremely small.

By using this structure, about half the space is required in the height direction as compared with the case where a dedicated shock absorber is arranged, and the shaking range of the device can be suppressed to about one third. It is very advantageous in terms of storage space. Shelf 2
12A between the base and the base 11 and the metal fitting 1 for fixing the device
The type and quantity of the sponges 12B and 12C of No. 3 are changed depending on the mass and size of the loaded device 4 and the earthquake resistance of the device. With the conventional method, it was very difficult to change the type and number of shock absorbers that were once set due to the mass and size of the loaded equipment and the earthquake resistance of the equipment. Can be easily changed. Compared with the conventional method, this structure has an advantage that it can be implemented at a very low price in terms of price. This structure can be used not only as a storage rack to be loaded on a moving body but also as an anti-vibration structure for an important electronic equipment storage rack that must operate even if an earthquake or the like occurs.

[0007]

As is apparent from the above description, according to the present invention, by using a sponge having a small shape and a low cost as a vibration isolator, the storage space of the device can be reduced and the cost can be reduced. In addition, it is possible to easily deal with a change in the mass of the device to be stored.
