[0014] 1. In this utility model, by aligning the mounting plate with the groove and inserting it, the plug-in block is compressed when the mounting plate is inserted into the groove due to the arc shape of one end of the plug-in block. It gradually moves into the mounting groove and compresses the spring until the plug-in block slides into the corresponding slot. Under the action of the spring, the plug-in block is pushed to reset and the mounting plate is inserted tightly. This achieves quick installation of the connector, avoids the time-consuming and laborious problem of traditional installation, and improves the overall work efficiency.

[0015] 2. In this utility model, by pulling the pull ring upwards, the knob is disengaged from the limiting groove. Then, rotating the knob drives the movable rod to rotate. The rotation of the movable rod drives the sleeve rod and gear to rotate. The gear drives the rack, and the rack drives the fixed plate and C-shaped clamp to move to the appropriate position. When the adjustment is complete, the movable rod is inserted into the sleeve rod, and the knob is locked into the limiting groove. This allows for flexible adjustment of the size of the installation cavity according to the thickness of the sound-absorbing panel. This not only improves the applicability of the device but also reduces installation problems caused by inconsistent thickness of the sound-absorbing panel, enhancing the operability of the device in different environments and scenarios.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, this embodiment proposes a gymnasium sound-absorbing panel fixing device, including a keel 1, a plurality of grooves 2 are provided on the front side of the keel 1, a plurality of mounting slots 3 are provided inside the keel 1 and on both sides of the grooves 2, a spring 4 is provided inside the mounting slots 3, a plug block 5 is slidably connected inside the grooves 2, a mounting plate 6 is slidably connected inside the grooves 2, a limit groove 7 is provided on the top of the mounting plate 6, an adjustment component is provided inside the mounting plate 6, and a sound-absorbing panel 16 is provided inside the adjustment component.

[0028] The purpose of this setup is that, during use, one of the mounting plates 6 is first aligned with the groove 2 on the keel 1, and the mounting plate 6 is inserted into the groove 2. When the mounting plate 6 is inserted into the groove 2, the shape of the arc-shaped plug 5 causes it to be squeezed, and the plug 5 begins to move into the mounting groove 3. During this process, the plug 5 not only gradually enters the mounting groove 3, but also compresses the spring 4 connected to it. The spring 4 not only provides resistance, but also pushes the plug 5 to move in the reset direction through elastic restoring force. As the mounting plate 6 continues to go deeper, the plug 5 will eventually slide to the matching slot position. At this time, the previously compressed spring 4 begins to release its stored energy, and under the action of this force, pushes the plug 5 to reset, thereby tightly and firmly locking the mounting plate 6 in the groove 2. At this time, the sound-absorbing plate 16 is inserted into the adjustment mechanism. The size of the mounting cavity can be adjusted according to the thickness of the sound-absorbing plate 16 through the adjustment mechanism. Then, the mounting plates 6 can be installed.

[0029] Preferably, one end of the spring 4 is fixedly connected to the inner wall of the mounting groove 3, and the other end of the spring 4 is fixedly connected to the side of the plug block 5 away from the groove 2. The purpose of this arrangement is that the spring 4 provides elastic force for the plug block 5 to reset.

[0030] Preferably, the outer side of the plug-in block 5 is slidably connected to the inside of the mounting groove 3, and one end of the plug-in block 5 is inserted into the inside of the mounting plate 6. The purpose of this arrangement is that the plug-in block 5 is slidably connected to the mounting groove 3, so that the plug-in block 5 can move stably, and the plug-in block 5 is inserted into the inside of the mounting plate 6 so that the mounting plate 6 can be stably installed.

[0031] Preferably, one end of the plug-in block 5 is arc-shaped. The purpose of this design is to allow the plug-in block 5 to be subjected to appropriate compression as the mounting plate 6 gradually penetrates into the groove 2, thereby generating the necessary deformation and gradually moving along the internal space of the mounting groove 3.

[0032] Example 2

[0033] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes an adjustment component including two sleeve rods 8. The outer side of the sleeve rod 8 is rotatably connected to the inside of the mounting plate 6. The inside of the sleeve rod 8 is slidably connected to a movable rod 9. A knob 10 is fixedly connected to the end of the movable rod 9 away from the sleeve rod 8. A gear 11 is fixedly connected to the outer periphery of the sleeve rod 8. A rack 12 is meshed with one side of the gear 11. A fixing plate 13 is fixedly connected to the inner side of the rack 12. A C-shaped clamp 14 is fixedly connected to the front side of the fixing plate 13.

[0034] The purpose of this setup is that, during use, the mounting plate 6 is first installed on the keel 1. Then, by pulling the upper and lower sets of pull rings 15, the knob 10 is disengaged from the limiting groove 7. Subsequently, the knob 10 is rotated to drive the movable rod 9 to rotate. The rotation of the movable rod 9 drives the sleeve rod 8 and the gear 11 to rotate. The gear 11 drives the rack 12, and the rack 12 drives the fixed plate 13 and the C-shaped clamping plate 14 to move to the appropriate position. The sound-absorbing plate 16 is then placed on the C-shaped plate. Then, the knob 10 is rotated in the opposite direction to drive the movable rod 9, the sleeve rod 8, and the gear 11 to reverse. The reverse rotation of the gear 11 drives the rack 12 to move in the opposite direction until the sound-absorbing plate 16 is clamped between the C-shaped plate and the keel 1. After installation, the movable rod 9 is inserted into the sleeve rod 8, and the knob 10 is engaged in the limiting groove 7, thus allowing the size of the mounting cavity to be flexibly adjusted according to the thickness of the sound-absorbing plate 16.

[0035] Preferably, the outer side of the fixing plate 13 is slidably connected to the inside of the mounting plate 6. The purpose of this arrangement is to enable the fixing plate 13 to move stably.

[0036] Preferably, the outer side of the rack 12 is slidably connected to the inside of the mounting plate 6. The purpose of this arrangement is to enable the rack 12 to move stably.

[0037] Preferably, the knob 10 is located inside the limiting groove 7, and a pull ring 15 is fixedly connected to the top of the knob 10. The purpose of this arrangement is that the knob 10 is located inside the limiting groove 7 so that the knob will not be accidentally touched when not in use, and the pull ring 15 makes it easy to remove the knob 10 from the limiting groove 7.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
