[0026] One end of the movable pin 18 is provided in a hemispherical shape.

[0027] One end of the upper protruding part 10 is provided with an inclined surface 19, a groove 20 is formed below the inclined surface 19 and located at a side end of the upper protruding part 10, one end of the movable pin 18 is in abutment with the groove 20.

[0028] The groove 20 is provided in an arc-shaped structure.

[0029] The cross section of the latch 8 and the latch slot 15 is provided in a right-angled trapezoidal shape.

[0030] Working principle:

[0031] Before assembly, the two adjacent sound-absorbing panels 1 each have a first joint 2 and a second joint 9.

[0032] The movable pin 18 inside the lower protrusion 4 on the first pair of connectors 2 is kept in an outwardly extended state under the action of the spring 17;

[0033] The inclined surface 19 and groove 20 of the upper protrusion 10 of the second pair of connectors 9 are prepared to mate with the movable pin 18.

[0034] During assembly, align the upper protrusion 10 of the second pair of connectors 9 with the lower connecting groove 6 of the first pair of connectors 2, and gently push it in.

[0035] During this process, the inclined surface 19 of the upper protrusion 10 contacts the movable pin 18 and pushes the movable pin 18 inward into the inner hole 16, while compressing the spring 17.

[0036] When the upper protrusion 10 is fully inserted into the lower connecting groove 6, the movable pin 18 pops out under the action of the spring 17 and gets into the groove 20 of the upper protrusion 10, thus achieving initial locking.

[0037] Meanwhile, the connecting protrusion 13 of the second connector 9 mates with the upper connecting groove 3 of the first connector 2, the third connecting surface 12 fits against the first connecting surface 5, and the fourth connecting surface 14 fits against the second connecting surface 7, thereby enhancing the stability of the connection.

[0038] Finally, the pin 8 is inserted into the pin slot 15, which further enhances the stability of the connection;

[0039] After the above steps, the two polyester fiber sound-absorbing panels are quickly and stably connected through the tight fit of the first pair of connectors 2 and the second pair of connectors 9.

[0040] This connection method is not only simple and easy to implement, but also effectively prevents the sound-absorbing panels from loosening or falling off during use;

[0041] When disassembly is required, simply pull the two sound-absorbing panel bodies 1 to the sides. At this time, the movable pin 18 compresses the spring 17 and retracts into the inner hole 16, the first connecting surface 5 and the third connecting surface 12 separate, and the connecting protrusion 13 separates from the upper connecting groove 3. Then, slightly lift the sound-absorbing panel body 1 on one side of the first joint 2. At this time, the lower protrusion 4 gradually disengages from the docking groove 11, and the pin 8 gradually disengages from the pin groove 15, allowing it to come out of the groove 20. Then, pull out the pin 8 to separate the two sound-absorbing panel bodies 1.

[0042] This disassembly method is also simple and quick, and will not damage the sound-absorbing panel.
