JPH09181459A - Seismic isolation structure of frame - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a seismic isolation structure of frame, allowing it to be installed and secured, without lifting electric equipment to be installed. SOLUTION: A seismic isolation structure 1 comprises a base 2 having through-holes 3, cylindrical support posts 4 having a female screw pressure-fitted or caulked to a member 5 having casters 6 near the posts and rubbers 7 held between the base 2 and member 5, each having a thickness with gaps a. A leveler 10 has a male screw 8 at the middle and plate 9 having a larger diameter than the hole 3 of the base 2 is inserted into the hole 3 and post 4. A vibration or shock received at the casters 6 during transporting is attenuated by the effect of the vibration-damping rubbers 7 into a reduced vibration at electronic apparatus directed mounted on the base 2. Rotating the leveler 10 in the lowering direction causes the member having the posts 4 having the screws to mesh therewith to move up until the casters 6 leave from the floor to result in a floor installation with the levelers 10 only.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing for an electronic device or the like, and more particularly to a vibration isolating structure for the housing.

[0002]

2. Description of the Related Art As a known example of the prior art, Shokai Sho 63-19.
No. 5140 is known.

[0003] This conventional vibration isolating structure of the housing will be described with reference to the drawings.

FIG. 4 is an external perspective view showing a conventional vibration isolating structure of the housing, FIG. 5 is a central sectional view of the vibration isolating structure of the housing of FIG. 4, and FIG. 6 is a conventional vibration isolating structure of the housing. It is a figure which shows the electronic device using.

[0005] In FIGS. 4 and 5, a vibration isolating rubber 21, which is a vibration isolating structure of a conventional housing, has a central portion of a metal substrate 22 protruding upward, and a support column 24 provided with a screw 23 is integrated with a rubber 25. It is molded. The anti-vibration rubber 21 is fixed to the side wall 27 of the electronic device 26 with a screw 28 as shown in FIG.
To absorb the vibration generated by the electronic device 26,
It attenuates and prevents transmission to the housing 29.

[0006]

A first problem of the above-mentioned conventional vibration isolating structure of a housing is that when an electronic device is installed, the device is lifted and fixed.

[0007] The reason is that the electronic device must be sandwiched from the left and right.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vibration-isolating structure for a housing which can be fixedly installed without lifting an electronic device to be installed.

Therefore, the vibration isolating structure of the housing of the present invention is fixedly installed without lifting the electronic device to be installed.

According to the vibration isolating structure of the housing of the present invention, the member having the cylindrical support having the female thread is moved upward by rotating the leveler having the male screw attenuated by the elastic rubber in a downward direction. As a result, the casters are separated from the floor and only the leveler is installed on the floor.

The vibration isolating structure of the housing according to the present invention comprises a member provided with a female screw and a caster, a base provided with a through hole which is fixed with an elastic rubber interposed therebetween and overlaps with the female screw,
It is composed of a male screw part screwed into a female screw, a shaft inserted into a through hole provided in the base, and a leveler provided with a plate larger than the through hole at the tip of the shaft.

[0012]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a view showing an embodiment of a vibration isolating structure of a housing of the present invention, FIG. 2 is a diagram for explaining the operation of the vibration isolating structure of the housing of FIG. 1, and FIG. It is a figure which shows the electronic device which used the vibration isolation structure of the housing | casing of the form of FIG.

In FIG. 1, a vibration isolation structure 1 according to the present embodiment is shown.
Is mounted on an electronic device 11 and has a base 2 provided with a through hole 3 and a cylindrical support 4 having a female thread by press-fitting, caulking, or the like, and a gap 5 in a member 5 provided with a caster 6 in the vicinity thereof. A rubber 7 having a thickness is sandwiched.
Leveler 1 having male thread 8 screwed to the center of leveler 10 and plate 9 having a larger diameter than through hole 3 provided in base 2
0 is inserted into the through hole 3 and the support 4.

Next, the operation of this embodiment will be described with reference to FIGS.

In FIG. 1, vibrations and impacts received from the casters 6 during transportation become reduced vibrations in the electronic device 11 shown in FIG.

Next, the case of installation will be described with reference to FIG.

FIG. 2 shows that when the leveler 10 is rotated in the downward direction, the member 5 having the cylindrical column 4 having meshing screws is moved upward, so that the casters 6 are separated from the floor surface and the leveler 10 is moved away from the floor. Only the floor will be installed.

FIG. 3 shows a state in which the vibration isolation structure 1 of the present embodiment is attached to the electronic device 11.

[0020]

As described above, the first effect of the vibration isolating structure of the housing of the present invention is that when an electronic device is installed, only the leveler attached to the bottom of the housing is lowered. An object of the present invention is to provide a vibration isolation structure for a housing.

The reason is that the vibration isolation structure of the housing of the present invention is as follows.
This is because the electronic device is mounted on the bottom surface, so that the device does not need to be lifted during installation.
