The side surfaces of the first auxiliary wall 2 and the second auxiliary wall 3 are hinged with a hole door 4 for covering the inserting hole 5.

The working conditions and principles of the embodiment are as follows:

when the indoor sound-proof wall needs to be installed, the indoor sound-proof wall is firstly pushed, so that the walking wheels 271 roll to drive the sound-proof wall to move, and then the indoor sound-proof wall moves to the corresponding position. Then, the hole door 4 on the first sub-wall 2 is opened to expose the plug hole 5, and at the moment, a rotary handle matched with the plug hole 5 and prepared in advance can be plugged into the plug hole 5, so that the rotary handle is connected with the plug hole 5 and coaxially rotates, and the first scroll bar 23 rotates along with the rotary handle. Then, the rotating handle is rotated to drive the first worm 23 to rotate, and further drive the first worm gear 24 to rotate, so that the rod barrel 25 rotates along with the first worm gear 24. The rotation of the rod barrel 25 generates a tendency of driving the first lead screw 26 to rotate, and the first lead screw 26 is limited by the rotation of the mounting plate 27, so that the first lead screw 26 slides upwards along the length direction of the rod barrel 25. The first screw rod 26 slides upwards to drive the mounting plate 27 to slide upwards together, so that the walking wheel 271 is gradually taken in the first cavity 21 through the through hole 22, the indoor sound insulation wall descends, and the lower end face of the first secondary wall 2 is abutted to the ground. The rotating handle is then pulled out and the aperture door 4 is closed.

Then, the hole door 4 of the second subsidiary wall 3 is opened, the inserting hole 5 is exposed, and the rotary handle is inserted into the inserting hole 5, so that the rotary handle is connected with the inserting hole 5 in a clamping manner for transmission, and the second scroll bar 32 rotates along with the rotary handle. Then, the rotating handle is rotated to drive the second worm 32 to rotate, and further drive the second worm wheel 33 to rotate, so that the rotating drum 34 rotates along with the second worm wheel 33. The rotation of the rotary drum 34 generates a tendency of driving the second screw 35 to rotate, and the second screw 35 is limited by the rotation of the resisting block 36, so that the second screw 35 slides upwards along the length direction of the rotary drum 34. The second screw 35 pushes the abutting block 36 to slide upwards, so that the abutting block 36 moves upwards to abut against the roof, when the rubber pad 361 abuts against the roof, the rotating handle stops rotating, and then the rotating handle is pulled out, so that the hole door 4 is closed. Therefore, the indoor sound insulation wall can be installed more conveniently, and the sound insulation effect of the indoor sound insulation wall is better.

When indoor sound-proof wall when needs are dismantled, open the hole door 4 of second auxiliary wall 3 earlier for spliced eye 5 exposes, pegs graft rotatory handle to spliced eye 5 again for rotatory handle and the transmission of 5 joint of spliced eye, and then make second scroll bar 32 follow rotatory handle and rotate. Then, the rotating handle is rotated reversely to drive the second worm 32 to rotate, and further drive the second worm wheel 33 to rotate, so that the rotating drum 34 rotates along with the second worm wheel 33. The drum 34 rotates to generate a trend of driving the second screw 35 to rotate, and the second screw 35 is limited by the rotation of the resisting block 36, so that the second screw 35 slides downwards along the length direction of the drum 34. The second screw 35 drives the abutting block 36 to slide downwards, so that the rubber pad 361 is gradually separated from the roof, finally the abutting block 36 is put into the first cavity 21, the rotation of the handle is stopped, the rotating handle is pulled out, and the hole door 4 is closed.

Then, the hole door 4 on the first secondary wall 2 is opened to expose the plug hole 5, and the rotary handle is plugged into the plug hole 5 to be in clamping transmission with the plug hole 5, so that the first scroll bar 23 rotates along with the rotary handle. Then, the rotating handle is rotated reversely to drive the first worm 23 to rotate, and further drive the first worm gear 24 to rotate, so that the rod barrel 25 rotates along with the first worm gear 24. The rotation of the rod barrel 25 generates a tendency of driving the first lead screw 26 to rotate, and the first lead screw 26 is limited by the rotation of the mounting plate 27, so that the first lead screw 26 slides downwards along the length direction of the rod barrel 25. The first screw rod 26 slides downwards to drive the mounting plate 27 to slide downwards together, so that the walking wheel 271 abuts against the ground through the through hole 22, then the walking wheel 271 gradually penetrates out of the through hole 22, the indoor sound insulation wall is gradually supported, and finally the walking wheel 271 completely extends out of the through hole 22. Then the rotation of the rotary handle is stopped, and the rotary handle is pulled out to close the hole door 4. The realization is to dismantling of indoor sound-proof wall for the position of indoor sound-proof wall is changeed in the adjustment, but reuse need not to destroy and rebuilds, and need not any time limit for a project, and is less to the interference of office staff work.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
