Further, the level adjusting unit 3 is formed with a cross-shaped handle 16 for rotation at the top. The coupling portion 14 and the handle 16 are integrally formed. Further, a rough adjustment screw hole 15 penetrating the level adjustment unit 3 is formed at the center of the upper portion of the level adjustment unit 3. In FIG. 2, a part of the rough adjustment screw hole 15 is shown in cross section. The coarse adjustment screw holes 15 are formed at a pitch larger than the screw pitch of the fine adjustment screw holes 12. As an example, the rough adjustment screw hole 15 is formed as a screw hole (female screw) having a pitch of 3 mm at M24.

  The support column 4 is made of metal, and a male screw that can be screwed into the coarse adjustment screw hole 15 is formed in the lower part of the support column 4. In addition, the support pillar 4 is formed with a flange-like locking portion 18 having a diameter larger than the screw diameter on the upper side of the portion where the screw is formed. Further, the support column 4 has a barrel portion 19 on the upper side of the locking portion 18 formed in a hexagonal nut shape. The hexagonal nut shape corresponds to an example of the engaging portion in the present invention, and is defined as a size that can be rotated by a spanner. Furthermore, the tip 20 above the support column 4 is formed in a trapezoidal cone shape.

  As shown in FIG. 1, the angle of the trapezoidal cone of the tip portion 20 is formed at an angle that makes surface contact with the chamfered portion 33 of the mounting hole 32 formed in the bottom portion 30 of the device supported by the vibration isolator adjuster 1. ing. That is, the tip portion 20 supports the weight of the device on the surface.

  As indicated by the white arrow in FIG. 2, the coupling portion 14 of the level adjustment portion 3 is screwed and coupled to the fine adjustment screw hole 12 in the upper portion of the vibration isolation main body portion 2. Further, the male screw of the support column 4 is screwed into the rough adjustment screw hole 15 of the level adjustment unit 3 to be coupled.

  Next, height adjustment when the vibration isolating adjuster 1 is mounted on a device will be described.

  In advance, the support column 4 is rotated to reduce the height of the tip 20 of the support column 4 so that the locking portion 18 of the support column 4 is brought into contact with the level adjusting unit 3 side. Further, the turning handle 16 of the level adjusting unit 3 is turned to bring the level adjusting unit 3 to the lowest state, and then the turning handle 16 is turned appropriately about several turns. The rotation handle 16 is set so that it can be rotated in either the right rotation or the left rotation.

  In this state, the vibration proof adjuster 1 is placed on the floor surface 40 on which the device shown in FIG. In this state, the device is still supported by the caster 35.

  Next, a spanner is engaged with the hexagonal body portion 19 of the support column 4 to rotate the support column 4 in a direction in which the tip end portion 20 of the support column 4 is raised. At this time, the handle 16 is supported and fixed so as not to rotate. When the tip 20 of the support pillar 4 is raised, the support pillar 4 fits into the mounting hole 32 in the bottom 30 of the device, and the trapezoidal cone-shaped portion of the tip 20 comes into surface contact with the chamfer 33. From this state, the support column 4 is further rotated with a tool so that the caster 35 is floated to a predetermined height. In this way, the vibration proof adjuster 1 can be mounted without lifting the device in advance.

  At this time, as shown in FIG. 3, the spacer 22 is inserted between the upper surface of the level adjusting portion 3 and the locking portion 18 of the support column 4. FIG. 1 shows a state in which two spacers 22 are inserted.

  After inserting an appropriate number of spacers 22, the support column 4 is fastened to the level adjustment unit 3 side, and the spacer 22 and the support column 4 are fixed to the level adjustment unit 3. As a result, the support column 4 is reinforced by the spacer 22 and the height is reliably fixed.

  When the vibration isolator adjuster 1 is placed directly below the mounting hole 32 of the device, if the mounting hole 32 and the tip 20 of the support column 4 are close to each other, the support column 4 is rotated. Alternatively, the caster 35 may be lifted to a predetermined height by rotating the handle 16. In this case, the locking part 18 of the support column 4 is used while being in contact with the upper part of the level adjusting part 3. Even in this case, the anti-vibration adjuster 1 can be mounted without lifting the device in advance.

  Subsequently, the anti-vibration adjuster 1 is attached to all the remaining mounting holes 32 formed in the bottom 30 of the device as described above. As an example, the mounting holes 32 are formed at the four corners of the device.

  Next, the handle 16 of each anti-vibration adjuster 1 is slightly rotated left or right so that the device is leveled with a level or the like, and the height of the tip 20 of the support column 4 is adjusted. In this case, since the pitch of the male screw of the coupling portion 14 of the level adjusting unit 3 is smaller than that of the male screw of the support column 4, the height changes only slightly compared to one rotation of the support column 4 itself. For this reason, the height can be finely adjusted by operating the handle 16. Further, since the handle 16 is attached, a slight fine adjustment can be easily performed with a small force.

  Repeat the fine adjustment until the device is level. Installation work ends when the equipment is leveled.

  Even if the device is activated to generate vibration, the anti-vibration effect can be obtained by the elasticity of the anti-vibration rubber 10.

By being formed in the trapezoidal cone shape, the device can be supported without the support pillar 4 penetrating the bottom surface 30 of the device. For this reason, dead space does not occur inside the device. Furthermore, if the position of the mounting hole 32 is formed in consideration of the size of the vibration proof adjuster 1, the vibration proof adjuster 1 can be mounted within the device size without protruding from the side surface of the device.

  Further, the level adjusting unit 3 is screwed into the fine adjustment screw hole 12 of the vibration isolation main body unit 2. For this reason, the height of the front-end | tip part 20 of the support pillar 4 attached | subjected to the upper part can be adjusted by rotating the handle | steering-wheel 16 of the level adjustment part 3. FIG. Therefore, the device can be supported by setting the vibration-proof adjuster 1 on the lower side of the device and adjusting the height of the tip 20 of the support column 4 to be high. For this reason, since the device can be mounted without floating in advance, the mountability is extremely good.

  Further, a coarse adjustment screw hole 15 is formed in the upper part of the level adjustment unit 3 at a pitch larger than the screw pitch of the fine adjustment screw hole 12, and the coarse adjustment screw hole 15 is provided on the lower side of the support column 4. By forming the male screw to be screwed into the periphery, the height of the tip 20 of the support column 4 can be largely adjusted by rotating the support column 4, and the height of the device is roughly adjusted. be able to.

  Further, according to the vibration isolator 1, the support column 4 is formed with the locking portion 18 having a diameter larger than the screw diameter on the upper side of the male screw formed on the lower side, and the locking portion 18. By enabling the spacer 22 to be disposed between the level adjusting unit 3 and the level adjusting unit 3, the support column 4 can be reinforced and the height of the support column 4 can be reliably fixed.

  Furthermore, since the support column 4 is formed in a hexagonal shape in which the body portion 19 can be engaged with a rotating tool such as a spanner, the support column 4 can be easily rotated. For this reason, it is possible to easily perform rough adjustment of the equipment height. Further, when the spacer 22 is disposed, the fixing can be easily performed by tightening the support column 4 to the level adjusting unit 3 side.

  In addition, although the example which formed the shape of the front-end | tip part 20 of the support pillar 4 in the trapezoid cone shape was demonstrated, like support pillar 4a, 4b shown by FIG. 4 (a) (b), it is the front-end | tip parts 20a and 20b. The shape can also be formed in a conical shape. Further, as shown in FIG. 6A, the body portion of the support column 4a is formed on at least a pair of parallel surfaces 24 (another example of the engaging portion) that can engage with a rotating tool such as a monkey wrench. You can also. Furthermore, as shown in FIG. 5B, a round hole 25 (another example of the engaging portion) can be formed in the body portion of the support column 4b. By inserting a round bar as a turning tool that fits into the round hole 25, the support column 4b can be easily turned.

  Moreover, the attachment hole 32 of the bottom part 30 of an apparatus may penetrate the bottom part. Further, the mounting hole 32 and the chamfered portion 33 may be an inverted conical recess into which the tip end portion 20 (20a, 20b) of the support column 4 is fitted.

  Furthermore, although the example of a structure which forms a male screw in the lower part of the support pillar 4 and performs rough adjustment of height by rotating the support pillar 4 was demonstrated, the support pillar 4 is fixedly formed in the level adjustment part 3. Thus, the height may be adjusted only by rotating the handle 16, that is, only by moving the level adjusting unit 3 up and down.
