[0020] Preferably, the surface of the pressure plate is provided with anti-slip teeth.

[0021] A method for connecting a music classroom wall connection structure comprises the following steps:

[0022] S1. After the vertical beam is installed along the hanging rod, align the external plate with the hanging rod so that the upper buckle tooth is located at the lower side of the hanging rod, and then move the external plate upward. At this time, the upper buckle tooth is restricted by the hanging rod, causing the slider compression spring to move downward in the slide groove, and the protrusion on the slider is used to push the rotating shaft to rotate along the spiral groove. During this process, the ring tooth on the rotating shaft drives the telescopic block and the lower buckle tooth to retract into the through groove. When the lower buckle tooth reaches the upper side of the stop rod, the release surface on the ring tooth disconnects the control of the telescopic block, and the tension spring pulls the telescopic block back, so that the lower buckle tooth is clamped on the stop rod from the upper side downward, and is locked by the anti-return clamping tooth and the upper buckle tooth;

[0023] S2. Before pushing up the external plate for installation, slide the cone block into the slide frame so that the cone block is arranged vertically on the surface of the sound insulation board and aligned with the through groove. When the external plate is subsequently installed, the lower buckle tooth is retracted into the through groove, and the telescopic block drives the ejector pin to move synchronously and pushes the column pin to move toward the cone block, so that the rectangular head passes through the rectangular hole and reaches the locking circular cavity. At this time, the ejector pin pushes the column pin and the rectangular head along the oblique teeth to deflect, and the rectangular head is misaligned with the rectangular hole, so that the cone block is locked together with the sound insulation board and the external plate;

[0024] S3. When the cone block needs to be removed, rotate the round pin so that the pressure plate reaches the rectangular head and rotates. After the rectangular head is aligned with the rectangular hole, the cone block can be removed. Alternatively, pull the slide bar so that the teeth on its surface push the column pin and the rectangular head along the gear ring to rotate, and then remove the cone block after aligning with the rectangular hole.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] When the cam is in a closed position, the upper and lower teeth are engaged with the guide rail and the upper and lower teeth are engaged with the guide rail, thereby preventing the guide rail from being disengaged and the upper and lower teeth from being engaged.

[0027] In the present invention, by sliding the cone block into the slide, the cone block is arranged vertically on the surface of the sound insulation board and aligned with the through groove. When the external plate is installed later, the telescopic block drives the ejector pin to move synchronously during the process of the lower buckle tooth retracting into the through groove, and pushes the column pin to move toward the cone block, so that the rectangular head passes through the rectangular hole and reaches the locking circular cavity. At this time, the ejector pin pushes the column pin and the rectangular head along the oblique teeth to deflect, and the rectangular head is misaligned with the rectangular hole, so that the cone block is locked together with the sound insulation board and the external plate. Compared with the existing cone block installation, the application of the above-mentioned slide can enable the operator to quickly arrange and pre-fix the cone blocks without having to find the installation points one by one, and the operation is more convenient and easy. In addition, the arranged cone blocks can be self-locking during the installation of the external plate without manual operation, which further improves the convenience of wall operations.

[0028] In the present invention, the round pin is rotated to make the pressure plate reach the rectangular head to rotate, and the cone block can be removed after the rectangular head is aligned with the rectangular hole, or the slide bar is pulled to make the pulling teeth on its surface push the column pin and the rectangular head to rotate along the gear ring, and the cone block is removed after it is aligned with the rectangular hole. Compared with the existing sleeve-insertion fixing structure of the cone block, the above-mentioned rectangular head for fixing the cone block can be disassembled individually or in large quantities of the entire row, which is convenient for the maintainer to make flexible choices according to actual needs and is more in line with practical use.

[0058] A method for connecting a music classroom wall connection structure comprises the following steps:

[0059] S1. After the vertical beam 1 is installed along the hanging rod 2, the external plate 3 is aligned with the hanging rod 2 so that the upper buckle tooth 64 is located at the lower side of the hanging rod 2, and then the external plate 3 is moved upward. At this time, the upper buckle tooth 64 is restricted by the hanging rod 2, causing the slider 62 to compress the spring 63 and move downward in the slide groove 61.

Before pushing up the external plate 3 for installation, slide the cone block 5 into the slide 6161, so that the cone block 5 is arranged vertically on the surface of the sound insulation board 4 and aligned with the through groove 69. When the external plate 3 is subsequently installed, the lower buckle tooth 611 is retracted into the through groove 69, and the telescopic block 610 drives the ejector pin 6165 to move synchronously, and pushes the pin 6163 to move toward the cone block 5, so that the rectangular head 6166 passes through the rectangular hole 6167 and reaches the locking circular cavity 6168. At this time, the ejector pin 6165 pushes the pin 6163 and the rectangular head 6166 along the oblique tooth 6164 to deflect, and the rectangular head 6166 is misaligned with the rectangular hole 6167, so that the cone block 5 is locked together with the sound insulation board 4 and the external plate 3.

[0061] S3. When the cone block 5 needs to be removed, rotate the round pin 61692 so that the pressure plate 61693 drives the rectangular head 6166 to rotate. After the rectangular head 6166 is aligned with the rectangular hole 6167, the cone block 5 can be removed. Alternatively, pull the slide bar 61696 so that the pulling teeth 61697 on its surface push the pin 6163 and the rectangular head 6166 to rotate along the gear ring 61694, and then align with the rectangular hole 6167 to remove the cone block 5.

After the vertical beam (1) is installed along the hanging rod (2), the external connecting plate (3) is aligned with the hanging rod (2) so that the upper buckle (64) is located at the lower side of the hanging rod (2), and then the external connecting plate (3) is moved upward. At this time, the upper buckle (64) is restricted by the hanging rod (2), causing the slider (62) to compress the spring (63) and move downward in the slide groove (61). The protrusion (68) on the slider (62) is used to push the rotating shaft (66) to rotate along the spiral groove (67). In this process, The ring gear (614) on the rotating shaft (66) drives the telescopic block (610) and the lower buckle gear (611) to retract into the through groove (69). When the lower buckle gear (611) reaches the upper side of the blocking rod, the release surface (615) on the ring gear (614) disconnects the control of the telescopic block (610). The tension spring (612) pulls back the telescopic block (610), so that the lower buckle gear (611) is buckled and clamped on the blocking rod from the upper side to the lower side, and is locked by the anti-return clamping tooth and the upper buckle gear (64). S2. Before pushing up the external plate (3) for installation, slide the cone block (5) into the slide frame (6161) so that the cone block (5) is arranged vertically on the surface of the sound insulation board (4) and aligned with the through groove (69). When the external plate (3) is subsequently installed, when the lower buckle tooth (611) is retracted into the through groove (69), the telescopic block (610) drives the ejector pin (6165) to move synchronously and pushes the column pin (6163) to move toward the cone block (5), so that the rectangular head (6166) passes through the rectangular hole (6167) and reaches the locking circular cavity (6168). At this time, the ejector pin (6165) pushes the column pin (6163) and the rectangular head (6166) along the oblique tooth (6164) to deflect, and the rectangular head (6166) is misaligned with the rectangular hole (6167), so that the cone block (5) is locked together with the sound insulation board (4) and the external plate (3); S3. When the cone block (5) needs to be removed, the round pin (61692) is rotated so that the pressure plate (61693) drives the rectangular head (6166) to rotate. After the rectangular head (6166) and the rectangular hole (6167) are aligned, the cone block (5) can be removed. Alternatively, the slide bar (61696) is pulled so that the pulling teeth (61697) on its surface push the column pin (6163) and the rectangular head (6166) to rotate along the gear ring (61694). After the rectangular hole (6167) is aligned, the cone block (5) can be removed.
