the method comprises the following steps: when the sound insulation board is used, the rotating board main body 621 is rotated, the arc-shaped groove II 625 and the arc-shaped groove I624 or the arc-shaped groove III 622 and the arc-shaped groove IV 623 on the upper end of the rotating board main body 621 drive the round rod 22 to move, and further drive the sound insulation board I1 and the sound insulation board II 9 to be unfolded;
step two: the two sliding plates 612 are driven to move reversely by rotating the plate main body 621 through the transmission rod 627;
step three: after the use, the rotating plate main body 621 is rotated in the reverse direction, so that the sound insulation plate I1 and the sound insulation plate II 9 move towards the center of the rotating plate main body 621, the occupied area is reduced, and finally the cover plate 3 is covered.
The working principle of the invention is as follows: when the device is used and is unfolded to the state shown in fig. 2, a user can use the device by locating the gap between the two sound insulation boards I1, and the support board 4 and the bracket 8 are bonded at the upper end of the top board 61 to adjust the position;
after use, the rotating plate main body 621 is rotated clockwise according to the state shown in fig. 10, the rotating plate main body 621 drives the arc-shaped groove ii 625, the arc-shaped groove i 624, the arc-shaped groove iii 622 and the arc-shaped groove iv 623 to rotate, the round bar 22 in the arc-shaped groove II 625 and the arc-shaped groove IV 623 moves along with the inner walls of the arc-shaped groove II 625 and the arc-shaped groove IV 623, because the center of the arc-shaped groove II 625 is superposed with the center of the rotating plate main body 621, the distance between the round rod 22 in the arc-shaped groove II 625 and the center of the rotating plate main body 621 is not changed, namely, the position of the sliding rod 21 connected with the round bar 22 and the baffle plate I1 is not changed, the round bar 22 in the arc-shaped groove IV 623 moves towards the direction of the outer circular surface of the rotating plate main body 621, therefore, the baffle II 9 is driven to move in the direction away from the center of the rotating plate 621, and the round bar 22 connected with the baffle II 9 moves from the center of the sliding groove 632 to the end close to the outer circular surface of the main body 631 of the bottom plate, after the round bar 22 moves to the joint of the arc-shaped groove II 625 and the arc-shaped groove I624 and the joint of the arc-shaped groove III 622 and the arc-shaped groove IV 623, the circular rod 22 moves into the arc-shaped groove I624 and the arc-shaped groove III 622, the arc-shaped groove I624 and the arc-shaped groove III 622 are arranged towards the center of the rotating rod main body 621, when the rotating rod main body 621 continues to rotate, the round rod 22 drives the sound insulation boards I1 and II 9 to move towards the center of the rotating board main body 621 at the same time until the round rod 22 moves to the tail end of the arc-shaped groove I624, at the moment, three sound insulation boards I1 are in contact with the outer circular surface of the bottom board 63, two sound insulation boards II 9 are abutted against the joint of two adjacent sound insulation boards I1, and finally the cover board 3 is covered, so that the occupied area of the device is reduced, the space is saved and the probability that ash falls into internal equipment is reduced after the cover board 3 is covered;
when the sound insulation board is used again, the rotating board main body 621 is rotated anticlockwise, the round rod 22 moves reversely according to the moving mode, the sound insulation boards I1 and II 9 move outwards simultaneously, after the round rod 22 moves to the connecting positions of the arc-shaped grooves II 625 and I624 and the connecting positions of the arc-shaped grooves III 622 and IV 623, the sound insulation boards I1 are fixed, and the sound insulation boards II 9 move towards the direction of the bottom board 63 until being embedded between the two sound insulation boards I1, namely the state shown in figure 2, at the moment, when a user records sound and videos, the sound insulation boards I1 and II 9 can effectively isolate external noise, and meanwhile, the user can ensure the sound recording quality through the reflection of the inner walls of the sound insulation boards I1 and II 9, so that the physical strength is saved;
when the rotating plate 621 rotates clockwise, that is, the rotating plate 621 is converted from the unfolded state to the closed state, the driving rod 627 is further driven to move, the driving rod 627 rotates clockwise, meanwhile, the driving rod 627 slides in the groove 6110, and moves from one end, far away from the arc surface of the sliding plate 612, of the groove body 6110 to one end, close to the arc surface of the sliding plate 612, due to the matching of the limiting T-shaped block 6112 and the limiting groove 6111, the sliding plate 612 can only move left and right in the state shown in fig. 2, and because the distance between the driving rod 627 and the circle center is unchanged, the groove body 6110 is arranged in parallel to the partition 615, and therefore, when the rotating rod 627 rotates clockwise, the rotating rod 627 moves from one end, far away from the arc surface of the sliding plate 612, of the groove body 6110 to one end, close to the arc surface of the sliding plate 612, and simultaneously drives the sliding plate 612 to move in the direction of the partition 615, and drives the rotating rod 613 to move the other sliding plate 612 in the direction of the partition 615, and finally, so that the two sliding plates 612 completely move into the groove 614 to finish contraction, and save the floor area;
when the rotating plate 621 rotates counterclockwise, the sliding plate 612 moves reversely according to the above-mentioned moving manner to complete the unfolding, so that the user can place more articles.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
