Such an isolation rack for computer equipment is classified into a full rack, a half rack, and a quarter rack depending on the length according to the vertical length, and the inside thereof is divided into at least one stage so that the computer equipment can be placed horizontally.

Inside the computer rack, there is a cooling fan, a small air conditioner, and an air circulation device installed to prevent malfunction or malfunction caused by the heat generated by the computer when the computer is operated.

An anti-vibration rack for computer equipment is also installed in the lower part of the rack to prevent the computer equipment stored inside it from being damaged by earthquake and vibration energy when the earthquake occurs.

On the other hand, the anti-vibration rubber installed in the rack exerts an anti-seismic function by the elastic force. Due to the structural limit, the anti-seismic effect is insufficient and there is a limit to not absorb the vibration energy.

In order to overcome this limitation, most of the floor of the computer room is equipped with an isolation floor with an isolation structure, and a computer equipment rack is placed on the floor, and the leg provided at the bottom is fixed to a seismic floor through a separate fixing hole Earthquake and vibration energy is prevented from being transmitted to the computer equipment rack, protecting the computer equipment.

However, as described above, the flooring installed on the bottom of the computer room requires a lot of installation cost, and therefore, there is a problem in that the economical burden of the installation is large when there is no economical margin.

If the number of seismic racks for computer equipment is not relatively large, installing an isolation floor on the floor of the computer room is economically inefficient and the space utilization is also inferior.

In addition, if the computer room needs to be moved as needed, it is disadvantageous to dismantle the installed floor on the floor of the existing computer room and reinstall it on the floor of the computer room to be moved.

The height of the legs 40 protruded from the lower fixing plate 26 is adjusted to be greater than the height of the caster 30 so that the frame 10 can be horizontally adjusted while the frame 10 is seated on the floor through the legs 40. [ .

Therefore, when the user grasps the seat plate 42 and rotates in one direction, the lift bolt 41 protrudes downward from the lower fixed plate 26 while the seating plate 42 is brought into close contact with the floor as shown in FIG. 1, Can be seated on the floor.

Conversely, when the seat plate 42 is rotated in the other direction, the lifting bolt 41 is inserted into the lower fixed plate 26 side, and the caster 30 is brought into close contact with the floor as shown in FIG. 3 to move the frame 10 .

Although not shown, an isolation pad (not shown) made of an anti-vibration rubber may be further installed on the lower portion of the seating plate 42 so as to prevent the earthquake and vibration energy transmitted from the floor when the earthquake occurs.

Lastly, the fixing means 50 is provided on the seismic means 20 to fix the seismic means 20 so that the seismic means 20 does not segregate when the frame 10 is moved.

That is, when the frame 10 is moved, the fixing means 50 is shaken due to impact or vibration transmitted through the caster 30 or pressure transmitted to the operator's hand when maintenance is performed, It is to solve the problem.

For this purpose, the fixing means 50 may be composed of a first connecting hole 51, a second connecting hole 52, a through hole 53 and an extension bolt 54 as shown in FIG.

The extension bolt 54 is integrally formed on the upper portion of the leg 40 and has a male thread corresponding to the first screw hole 51a and the second screw hole 52a formed on the outer surface thereof.

That is, when the extension bolt 54 is lowered to the first height so as to contact the floor by rotating the leg 40 in one direction, the extension bolt 54 is separated from the first screw hole 51a of the first connector 51 The upper plate 22 and the lower plate 24 are separated from each other while being screwed to the second screw hole 52a of the second connection port 52. [

When the extension bolt 54 is raised to a second height higher than the first height so that the caster 30 is brought into contact with the floor by rotating the leg 40 in the other direction, And the upper plate 22 and the lower plate 24 are connected to each other while being screwed to the first screw hole 51a of the first connection hole 52 and the second screw hole 52a of the second connection hole 52. [

Therefore, when the leg 40 is in contact with the floor, the seismic countermeasures 20 can be performed to protect the computer equipment in the event of an earthquake. When the legs 40 do not touch the floor, The seismic isolation means 20 does not perform the seismic motion so that the computer equipment can be prevented from being shaken and impacted during the movement or maintenance.

However, in the above structure in which the extension bolt 54 extends integrally with the leg 40, though not shown, the upper fixing plate 21 and the lower fixing plate 26 are vertically penetrated so that the facing means 20 is fixed (Not shown) which is provided on the lower surface of the main body.

Therefore, when the legs 40 are not in contact with the floor, the upper and lower fixing plates 21 and 26 are vertically connected to each other by the auxiliary fixing means, 10) can be safely protected by not shaking the computer equipment.

Although not shown, the isolating means 20 may also be configured as a fixing bolt (not shown) having a configuration separate from the legs 40, instead of the extension bolts 54 integrally formed in the upper portion of the legs 40. That is, it may be constituted by the first connection hole 51, the second connection hole 52, the through hole 53 and the fixing bolt.

Since the fixing bolt is separate from the leg 40, the fixing bolt may be inserted into the through hole 53 from the lower portion of the lower fixing plate 26 regardless of the operation of the leg 40, And the first connection port 51 and the second connection port 52 in this order.

Since the upper plate 22 and the lower plate 24 are connected to each other, the seismic isolation unit 20 can not perform the seismic motion, and the frame 10 can be safely moved or easily maintained while protecting the computer equipment .

As shown in FIG. 4, when the plurality of knockout racks 100 for computerization are installed in a left and right direction, the frame 10 or the upper fixing plate 21 of the two adjacent racks 100 for computing equipment are connected The connecting plate 60 may be formed of a metal plate.

The connecting plate 60 prevents the plurality of counterparts of the plurality of counterparts provided in the left and right continuous seats when the seismic countermeasures 20 are seated in the event of an earthquake.

At this time, one end of the connection plate 60 is fixed to the left side counterclockwise rack 100 and the other side is fixed to the right side counterclockwise side rack 100 by the plurality of fastening bolts 61.

The above-described embodiments are merely illustrative, and various modifications may be made by those skilled in the art without departing from the scope of the present invention.
