5 is a cross-sectional view illustrating a detachable part 84, a release part 90, and an interlocking part 106 of a seismic switchboard equipped with a vibration-isolating device housing according to another embodiment of the present invention.

5, the opening and closing part 16 of the seismic switchboard provided with the vibration isolator housing according to another embodiment of the present invention has one end in the installation hole 14 so as to open or close the installation hole 14. A cover member 17 that is rotatably installed by the branch portion 82a, and a detachable portion 84 for closing the installation hole 14 by coupling the other end of the cover member 17 to the installation hole 14, and a worker The release part 90 which releases the closed state of the detachable part 84 by the operation of, and the release part so that the operator can easily mount and open the opened cover member 17 when opening the installation hole part 14 By the operation of 90, the cover member 17 is transferred by converting the release operation of the release part 90 to the operation of the spacer 100 and the spacer 100 protruding upward of the floor panel 12. Includes linkage 106.

Therefore, after transporting the cabinet 10 on which the anti-vibration unit 50 is installed to the construction site, the operator opens the cover member 17 by operating the release unit 90 after the cabinet 10 is set upright on the ground. Since the opening operation of the release part 90 is converted and transmitted by the operation of the linking part 106, the restraint of the cover member 17 is released and the cover member 17 is moved to the bottom panel. (12) Since it is arranged to protrude upward, the operator can easily mount and open the cover member 17, insert the anchor through the installation hole 14, and install the anchor on the ground through the fixing hole 56c. 2 It is possible to fix the supporting panel 56a to the surface.

By repeating the installation of the anchor as described above, when all the vibration-proof units 50 installed at each edge of the cabinet 10 are fixed to the ground and the cover member 17 is pressed toward the installation hole 14, the release unit 90 ) And the spacer 100 is deformed by the pressing force of the cover member 17, and then the cover member 17 is constrained in a closed state by the operation of the detachable part 84 to complete the installation of the vibration isolation unit 50. .

The detachable part 84 of this embodiment includes a hook member 86 protruding from the end of the cover member 17, and a coupling groove part from the inner wall of the hook member 86 into which the hook member 86 is inserted so as to be engaged with the hook member 86. It includes a locking hook 87 protruding in the inward direction, and a first elastic member 88 that provides an elastic force for pressing the locking hook 87 in the inner direction of the coupling groove.

Therefore, when the cover member 17 is rotated toward the installation hole 14 and pressed, the hook member 86 is inserted into the coupling groove and the inclined surface of the locking hook 87 is pressed and retracted. At this time, the locking hook 87 As the first elastic member 88 is compressed, the hook member 86 is inserted to the inside of the coupling groove, and when the insertion of the hook member 86 is completed, the hook 87 is locked by the restoring force of the first elastic member 88. As the coupling groove protrudes in the inner direction, the hook member 86 and the locking hook 87 are engaged to complete the restraint of the cover member 17.

The release part 90 of this embodiment is formed in the same or similar shape as the lever member 92 and the lever member 92 that slides along the groove formed concave in the bottom panel 12, and the bottom panel 12 The auxiliary lever 94 that slides along the inner space and the lever member 92 and the auxiliary lever 94 are connected and extended from the connecting rod 107 for simultaneous movement, and are released connected to the rear surface of the locking hook 87 Includes bar 96.

The lever member 92 is slidably installed along the rail groove 92a so as to be slidable along the groove formed in the floor panel 12, and the lever member 92 is mounted on the upper surface of the lever member 92 while pressing it with the operator's hand or the human body. The uneven portion 92b is formed to allow the member 92 to slide.

In addition, the spacing part 100 of this embodiment includes a spacing protrusion 102 that is installed so as to protrude upward from the bottom of the coupling groove so that the inner end of the hook member 86 can be pressed upward, and the spacing protrusion 102 ) And a second elastic member 104 that provides an elastic force for pressing upward.

Therefore, when the hook member 86 is retracted and the hook member 86 is released, the spacer protrusion 102 rises due to the restoring force of the second elastic member 104, and rises. While the inclined surface formed on the upper surface of the spaced protrusion 102 presses the inclined surface of the hook member 86 upward, the hook member 86 and the cover member 17 are lifted upward by a certain amount, while the cover member 17 is moved to the bottom panel. Make it rise apart from (12).

The linkage part 106 of this embodiment is a connecting rod 107 extending from the auxiliary lever 94 to the spacing protrusion 102, and at the end of the connecting rod 107 opposite to the lower end of the spacing protrusion 102. It includes a pressure inclined portion 108.

Here, the pressure inclined surface portion is made at the same or similar angle to the inclined surface formed at the lower end of the spacing protrusion 102, and forms a slope that increases in height toward the end of the connecting rod 107, so that the operator separates the lever member 92 The auxiliary lever 94 is also moved in the same direction as the lever member 92 as it is pulled away from the 102 to move the connecting rod 107, and the pressure inclined portion 108 formed at the end of the connecting rod 107 The spaced protrusion 102 is raised while pressing the lower end of the spaced protrusion 102 upward.

The spaced protrusion 102 that rises as described above presses the lower end of the hook member 86 upward to lift the cover member 17 apart from the bottom panel 12 upwardly.

Thereafter, when the operator releases the lever member 92, the locking hook 87 protrudes in the inner direction of the coupling groove due to the restoring force of the first elastic member 88 and the second elastic member 104. At this time, the hook member 86 ) And the inclined surface formed on the upper surface of the locking hook 87 are arranged in close contact with each other, so that the locking hook 87 is in a state of supporting the hook member 86, so the other end of the cover member 17 The silver is raised from the floor panel 12 to achieve a spaced state.

After the installation of the anti-vibration unit 50 is completed, the operator presses the cover member 17 toward the floor panel 12 and presses the first elastic member 88 to compress the hook 87 and retract the hook member 86. ) Is inserted to the inner end of the coupling groove and is constrained to the closed state again.

As a result, the vibration isolator installed on the bottom of the switchboard can be transferred to the site while the vibration isolator is installed on the bottom of the cabinet, and the vibration isolator installed on the bottom of the cabinet can be installed on the ground without any separate work or reassembly work, so the time and cost required to install the switchboard The vibration isolator that can reduce the amount of energy, and is equipped with an installation hole and an opening and closing part for installing the vibration isolator at the bottom of the cabinet, so that the opening of the bottom of the cabinet can be easily closed after installation of the vibration isolating unit and the cabinet is completed, thereby promoting the convenience of the operator. It is possible to provide a seismic switchboard with a housing.
