Description

DETAILED DESCRIPTION OF THE INVENTION “Industrial field of application” The present invention relates to a case which is used in a case of an optical measuring instrument for inputting spatial light and which resists vibration.

“Prior Art” In order to suppress the vibration of the housing of a vibration-proof device, conventionally, a vibration-isolating foot having a vibration-isolating function like a rubber foot is attached to the bottom surface of the housing, which causes normal vibration. The housing is placed on the floor so that the vibration of the floor is not transmitted to the housing by the vibration isolation foot. Alternatively, the housing is placed on the vibration isolation table and used without using the vibration isolation foot.

"Problems to be solved by the device" When used in cooperation with other equipment that requires vibration isolation,
If other equipment does not have an anti-vibration foot, it is necessary to place both equipment on the anti-vibration table and use it. The elasticity of the legs sometimes caused unnecessary resonance in the housing.

On the other hand, when using the case on the vibration isolation table without using the vibration isolation foot, it is necessary to move the vibration isolation table when changing the place of use, and the vibration isolation table is relatively large. Yes,
Relocation work is difficult. If the vibration isolation table cannot be prepared, the device cannot be used.

[Means for Solving the Problem] In the present invention, a vibration isolation foot having a vibration isolation function and a rigid rigid foot having no vibration isolation function are attached to a bottom surface of a housing. One of the two is provided with a projecting length adjusting means capable of taking a projecting position and a retracted position from the other.

According to this configuration, when arranging the housing on a normal floor with vibration, the vibration-isolated foot is projected from the rigid foot by adjusting the projection length adjusting means, and the housing is supported on the floor by the vibration-isolated foot. Vibration isolation feet suppress the transmission of vibrations from the floor to the housing. When arranging the housing on the vibration isolation table, adjust the protrusion length adjustment means to project the rigid foot from the vibration isolation foot, and support the housing on the vibration isolation table with the rigid foot to isolate the vibration isolation foot. Separate from the table. Therefore, unnecessary resonance due to the elasticity of the vibration isolation foot does not occur.

"Embodiment" FIG. 1 shows an embodiment of the present invention. The housing 11 is, for example, a housing of a measuring instrument, and is one that resists vibration. An anti-vibration foot 12 such as a rubber foot having an anti-vibration function is attached to the bottom surface of the housing 11. In this example, the anti-vibration feet 12 are attached to the four corners of the bottom surface of the housing. Further, rigid legs 13 made of a rigid body such as metal and having no vibration isolation function are attached to the bottom surface of the casing 11.

In this example, when the protrusion length adjusting means is provided on the rigid foot 13, a screw 14 is formed on the peripheral surface of the rigid foot 13, and the screw 14 is screwed into the screw hole formed on the bottom surface of the housing to The protrusion 15 of the rigid foot 13 from the bottom surface of the housing can be adjusted by rotating the collar 15 of the body 13. This is a case where three rigid legs 13 are attached to the bottom face of the housing at three apexes of a triangle.

When the housing of the present invention is used by placing it on a normal floor 16 with vibration, as shown in FIG. 2, the rigid foot 13 is rotated to retract it from the vibration isolation foot 12, The housing 11 is supported on the floor 16 by. The vibration of the floor 16 is suppressed by the vibration isolation foot 12 and is not transmitted to the housing 11, so that the vibration of the housing 11 can be suppressed.

When the housing 11 is used by arranging it on the vibration isolation table 17 as shown in FIG. It is supported on the vibration isolation table 17. At this time, the anti-vibration foot 12 is separated from the anti-vibration base 17, and there is no possibility that unnecessary elasticity will occur due to the elasticity of the anti-vibration foot 12.

In the above, the protruding length of the rigid foot 13 can be adjusted, but
The length of 13 may be fixed and the protruding length of the vibration isolation foot 12 may be adjustable.

“Effect of device” As described above, according to this device, the vibration isolation foot 12 and the rigid foot 13
By attaching both and, at least the length of one of them can be adjusted, by supporting the vibration isolation on the normal floor with the vibration isolation foot, and by supporting the vibration isolation table with the rigid foot,
It can be used satisfactorily without being affected by vibrations on both normal floors and vibration isolation tables.
