Preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings. The terms or words used in the present specification and claims are not to be interpreted in a limiting sense in a general or dictionary sense, and are to be interpreted as concepts conforming to the technical idea of the present invention on the basis of the principle that the inventor appropriately defines the concept of the terms in order to explain his own invention in the most preferable way.

Therefore, the embodiment described in the present specification and the configuration shown in the drawings are only the most preferable embodiment of the present invention and do not represent all the technical ideas of the present invention, and therefore it is understood that various equivalents and modifications can be substituted for the embodiment.

As shown in fig. 2 to 3a and 3b, the shock absorbing, restoring and absorbing device 1 of the present invention includes: a support case 10 having an open upper surface, a support 12 having a screw hole 12-2 formed at a central portion of an inner bottom surface thereof, and an insertion hole 14 formed at a bottom surface of an outer circumference of the support 12; a mounting case 20 having a through hole 22-2 formed at a central portion thereof for receiving the supporter 12 of the support case 10 therein, a mounting supporter 22 formed at an outer circumferential surface thereof with an inclined surface portion 22-4, and a mounting groove portion 24 formed at an upper portion of the mounting supporter 22 for mounting and coupling various vibration devices; a buffer member 30 inserted into and coupled to the insertion hole 14 of the support case 10, and formed with an elastic support 32 protruded from a vertical direction for supporting the mounting support 22 of the mounting case 20 and buffering impact; and a fixing bolt 40 coupled to a screw hole 12-2 formed at the supporting member 12 of the supporting case 10 and having a buffer washer 42 formed at an upper portion thereof to buffer an impact for preventing the detachment of the mounting case 20.

As described above, the shock absorbing, restoring and absorbing device 1 according to the present invention is configured such that, as shown in fig. 4, the object 100 to be vibrated is mounted and coupled to the mounting groove portion 24 of the mounting case 20, and when vibration occurs during operation or due to impact, the object can be stably and rapidly restored and supported by the fixing bolt 40 coupled to the screw hole 12-2 of the support 12 formed in the support case 10 and the elastic support 32 inserted into the cushion member 30 coupled to the insertion groove 14 of the support case 10, thereby absorbing the impact.

That is, the supporter 12 of the support case 10 is built in the through hole 22-2 formed in the mounting supporter 22 of the mounting case 20, and the inclined surface portion 22-4 formed on the outer circumferential surface of the mounting supporter 22 of the mounting case 20 is supported by the elastic supporter 32 of the buffering member 30 protruding toward the insertion hole 14 of the support case 10, and is fixed by the fixing bolt 40 coupled to the screw hole 12-2 of the support case 10, so that, during operation and shock due to shock, shock is buffered by the elastic supporter 32 of the buffering member 30 and the cushion washer 42 of the fixing bolt 40, and restoration support is performed by the elastic supporter 32 of the buffering member 30.

The cushion member 30 and the cushion washer 42 of the fixing bolt 40 are formed of a rubber material having an elastic force, so that the mounting supporter 22 for stably fixing and supporting the mounting case 20 can absorb shock impact and can be restored.

As described above, in order to support the mounting supporter 22 of the support case 20 by the elastic supporter 32 of the cushion member 30 and provide restoration efficiency, and to be easily detachable from the inside of the elastic supporter 32 of the cushion member 30, it is preferable that the inclined surface portion 22-4 formed on the outer circumferential surface of the mounting supporter 22 of the mounting case 20 is formed of a tapered shape forming an inclined surface of 30 ° to 50 ° as shown in fig. 5.

That is, if the inclined surface portion 22-4 contacting the upper portion of the elastic supporting member 32 is manufactured in a tapered shape, as shown in fig. 6a, when the mounting supporting member 22 is built in the elastic supporting member 32 in a form in which the buffer member 30 is perpendicular by 90 °, the mounting supporting member 22 of the mounting case 20 can be easily detached from the inside of the elastic supporting member 32.

Further, the inclination angle of the inclined surface 22-4 is formed at 30 ° to 50 °, so that, as shown in fig. 6b, when a slight shock impact occurs to the mounting case 20 and a vibration occurs during operation, an area D1 where the mounting stay 22 of the mounting case 20 and the elastic stay 32 of the shock absorbing member 30 are in close contact with each other is small, and thus the shock can be absorbed and restored, and as shown in fig. 6c, when a large shock occurs, an area D2 where the mounting stay 22 of the mounting case 20 and the elastic stay 32 of the shock absorbing member 30 are in close contact with each other is large, so that the shock can be absorbed and restored, and thus, the impact spreading effect can be obtained by making the areas D1 and D2 different according to the shock transmitted to the elastic stay 32 of the shock absorbing member 30.

As described above, in order to restore the vibration of the vibration target 100 attached to the mounting case 20 during operation and when an impact is applied thereto and to improve the efficiency of absorbing the impact, it is preferable that an impact buffering member 34 having an air layer is further formed on the outer circumferential surface of the upper portion of the elastic support 32 of the buffering member 30, as shown in fig. 7.

That is, the impact buffering member 34 having an air layer is further formed on the upper outer circumferential surface of the elastic support 32 of the buffering member 30, thereby obtaining an effect of improving the impact absorption.

As described above, in order to absorb the shock by the shock absorbing member 34 and improve the restorability, it is preferable that, as shown in fig. 8, a shock absorbing and restoring member 50 is provided, in which an elastic spring 52 is provided at a lower portion of an outer periphery of an inner bottom surface of the support case 10 to support the mounting supporter 32 of the shock absorbing member 30 and improve the restorability, and a buffer material 54 having an inclined surface formed on a reverse surface equivalent to the elastic supporter 32 of the shock absorbing member 30 is provided at an upper portion of the elastic spring 52.

That is, as shown in fig. 9a, when the mounting bracket 32 of the shock absorbing member 30 performs 1-time shock absorption and the excessive shock is absorbed by the shock absorbing member 54 of the shock absorbing and restoring member 50 when the mounting case 20 is slightly shocked and shaken due to operation, and the shock absorbing and restoring member 50 receives a shock impact larger than the excessive shock impact and shakes due to operation, as shown in fig. 9b, the mounting bracket 32 of the shock absorbing member 30 is pressed against the inclined surface of the shock absorbing member 54 formed in the shock absorbing and restoring member 50 to move downward and to move upward by the elastic spring 52 of the shock absorbing and restoring member 50, thereby improving restorability and absorbing the shock by the shock absorbing member 54 of the shock absorbing and restoring member 50.

Referring to fig. 10 to 15, a shock absorbing and restoring shock absorbing device 1' according to still another embodiment of the present invention includes: a support case 10 'including a support member 12' and a support plate 16 ', the support member 12' being formed to extend from an upper direction, the support plate 16 'being formed with a screw hole 12' -2 at a central portion thereof, the support plate 16 'being formed in a plate shape at a lower portion of the support member 12', being formed with a plurality of insertion holes 16 '-4, and being formed with a plurality of 1 st support protrusions 16' -6 at a bottom surface thereof; the mounting case 20 ' includes a mounting support 22 ', a through hole 22 ' -2 is formed at the center of the mounting support 22 ', an inclined surface 22 ' -4 is formed at the outer circumferential surface of the support 12 ' for accommodating the support case 10 ', and a mounting groove 24 ' for mounting and coupling the vibration object is formed at the upper part of the mounting support 22 '; a buffer member 30 'including an elastic support 32' and a buffer base 36 ', the elastic support 32' extending in an upper direction to form an inner space capable of accommodating the mounting support 22 'of the mounting case 20', the buffer base 36 'being formed at a lower portion of the elastic support 32' and having a plurality of buffer protrusions 36 '-4 inserted into and coupled to the plurality of insertion holes 16' -4 and a plurality of 1 st insertion grooves 36 '-6 for inserting and coupling the plurality of 1 st support protrusions 16' -6 formed at an inner bottom surface thereof; a fixing bolt 40 'coupled to the screw hole 12' -2 of the supporter 12 'formed at the support case 10' for preventing the detachment of the mounting case 20 'and formed with a buffering washer 42'.

At this time, the fixing bolt 40 'and the mounting case 20' are substantially the same as the fixing bolt 40 and the mounting case 20 in fig. 2 to 9b described above, and therefore, a repetitive description thereof will be omitted below. In the shock absorbing and restoring vibration damping device 1 ' according to still another embodiment of the present invention, the inclined surface portion 22 ' -4 of the mounting brace 22 ' of the mounting case 20 ' is also formed to have a tapered shape with an inclination angle of 30 ° to 50 °, so that when the mounting case 20 ' is shaken by the impact and operation of a small shock, the shock can be buffered and restored. Therefore, the following description focuses on the characteristic configurations of the shock absorbing, restoring and absorbing device 1 ' of yet another embodiment of the present invention, i.e., the support case 10 ' and the shock absorbing member 30 '.

In yet another embodiment of the present invention, as shown in the drawings, the support plate 16 'of the support case 10' may be manufactured in a circular plate shape. It goes without saying that the support plate 16' may be formed in other shapes than a circular shape, but the description will be centered on the drawings in this specification.

At this time, the plurality of insertion holes 16 ' -4 are formed at regular intervals along the circumference of the circular support plate 16 ', and the plurality of 1 st supporting protrusions 16 ' -6 are formed at regular intervals along the outer circumference of the bottom surface of the circular support plate 16 ' adjacent to the formation positions of the plurality of insertion holes 16-4 '.

That is, fig. 16 to 19 are diagrams illustrating a shock absorbing, restoring and absorbing device 1 'according to still another embodiment of the present invention illustrated in fig. 10 to 15, in which the shape of the shock absorbing member 30' is changed. Accordingly, the shock absorbing, restoring and absorbing device shown in fig. 16 and 17 can also be applied substantially similarly to the technical features of the support case 10 ', the mounting case 20 ', and the fixing bolt 40 ' described with reference to fig. 10 to 15. The buffer member 30 ″ of fig. 16 to 19 has an inner shape of the buffer member 30 ″ as a structure other than the outer shape, i.e., an outer appearance, and the technical features described with reference to fig. 10 to 15 are substantially the same as those of the bracket groove 36 '-2, the buffer protrusions 36' -4, the 1 st insertion groove 36 '-2, the 2 nd insertion groove 36' -8, and the like. Therefore, the description overlapping with the above description is omitted below, and only the shape feature of the shock-absorbing member 30 ″ according to another embodiment of the present invention will be described with reference to fig. 16 to 19.

Referring to fig. 16 to 19, the cushion base 36 'of the cushion member 30 ″ according to another embodiment of the present invention includes a plurality of reinforcing ribs (rib) 36' -5 formed to protrude at regular intervals such that the outer side surfaces form inclined surfaces.

In this case, a plurality of 2 nd bottom grooves 36 '-7 are formed in the central support portion 36' -9 and the peripheral support portion 36 '-10 of the outer bottom surface of the buffer base 36'. In this case, the 2 nd bottom surface groove 36 ' -7 is formed on an extension line connecting the central support portion 36 ' -9 to the peripheral support portion 36 ' -10 with the through hole 36 ' -1 of the buffer base 36 ' as a center. In this case, the plurality of 2 nd bottom grooves 36 '-7 are disposed at a uniform angle on the outer bottom surface of the buffer base 36', see fig. 19.

As described above, if the 1 st bottom surface groove 36 '-3 and/or the 2 nd bottom surface groove 36' -7 are formed on the outer bottom surface of the cushion pan 36 ', when the outer bottom surface of the cushion pan 36' comes into contact with the floor surface, the suction with the bottom surface can be prevented.

According to the vibration-absorbing, restoring and preventing device of the embodiment of the present invention, due to the structural features described above, when vibration is transmitted to the mounting case to which various vibration objects are attached, the impact due to the vibration can be absorbed or dispersed, and the support can be restored quickly.
