A wall-mounting device for sound-absorbing composite panels with concealed clips

Abstract

This invention discloses a wall fixing device for sound-absorbing composite panels with a concealed buckle, comprising a base and a movable seat. The base has a pair of side plates integrally formed on its front side, with a sliding groove on the inner bottom of each side plate. Sliding blocks on both sides of the movable seat are slidably connected to the sliding grooves on the inner sides of the side plates. A worm gear is rotatably connected to the center of the movable seat. Both ends of the shaft connected to the worm gear are equipped with traveling gears, which mesh with a rack and pinion in a rack slot. This invention allows the worm gear to be rotated by inserting a long bolt cutter into the gap between the sound-absorbing composite panel and the wall using an internal hexagonal wrench. The worm gear then meshes with the worm wheel, causing the traveling gears to mesh with the rack and pinion in the side plate slots. This allows the movable seat to slide back and forth along the guide grooves, thereby adjusting the gap between the sound-absorbing composite panel and the wall, facilitating the adjustment of the panel's flatness.

Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and in particular to a sound-absorbing composite panel wall fixing device with a hidden buckle. Background Technology

[0002] Sound-absorbing composite panels are a type of material that combines high-density sound-absorbing foam with structural panels. They are widely used to reduce sound reflection and improve sound insulation. Their core advantage lies in their ability to effectively absorb sound propagating through the air. They are commonly used in various locations such as walls, ceilings, and floors. Traditional wall fixing methods typically involve screws, glue, or hidden clips between the sound-absorbing composite panel and the wall. However, traditional hidden clips, once installed in the wall, make it inconvenient to adjust the flatness of the sound-absorbing composite panel surface, requiring repeated adjustments to the installation depth. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a sound-absorbing composite panel wall fixing device with a hidden buckle, which can more accurately solve the problems described above.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a sound-absorbing composite board wall fixing device with a hidden buckle, including a base and a movable seat. The base has a pair of side plate seats integrally formed on the front side, and the inner bottom of the side plate seats is provided with a sliding groove. The bottom two sides of the movable seat are integrally formed with sliders, and the sliders on both sides of the movable seat are slidably connected to the sliding grooves provided on the inner side of the side plate seats. The front side of the movable seat is integrally formed with a fastening frame, and the fastening frame has a fastening slot. The side plate seats have a rack slot. The middle of the movable seat is rotatably connected to a worm gear. Both ends of the rotating shaft connected to the worm gear are provided with traveling gears, and the traveling gears are meshed with the rack in the rack slot. The movable seat is rotatably connected to a worm on one side of the worm gear, and the worm is meshed with the worm gear. The worm is connected to an inner shaft core arranged coaxially, and the upper end of the inner shaft core is provided with an internal hexagonal wrench.

[0006] Furthermore, the inner shaft core is a splined shaft, and the inner shaft core is slidably connected to the middle part of the worm gear.

[0007] Furthermore, the inner shaft core extends through the bottom end of the worm gear, and the bottom end of the inner shaft core is connected to a movable limiting plate. A fixed limiting ring is provided at the bottom of the movable seat corresponding to the position of the movable limiting plate.

[0008] Furthermore, the top of the movable limiting plate is provided with annular limiting serrations, and the bottom of the fixed limiting ring is provided with annular limiting serration grooves that cooperate with the annular limiting serrations.

[0009] Furthermore, a return spring is connected between the fixed limiting ring and the movable limiting disc, and the return spring is sleeved outside the inner shaft core.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a long bolt cutter to insert the internal hexagonal wrench at the upper end of the worm gear along the gap between the sound-absorbing composite panel and the wall. This allows the worm gear to rotate and drive, and the worm gear to mesh with the worm wheel. This, in turn, allows the traveling gear to mesh with the rack slot on the side plate seat. This allows the movable seat to slide back and forth along the guide of the slide groove, thereby adjusting the gap between the sound-absorbing composite panel and the wall, and facilitating the adjustment of the flatness of the sound-absorbing composite panel.

[0012] 2. After the movable seat is adjusted to a suitable position, the pressure on the inner shaft core is released. Under the action of the return spring, the inner shaft core springs back upward until the annular limiting sawtooth of the movable limiting plate at the bottom of the inner shaft core re-engages with the annular limiting sawtooth groove of the fixed limiting ring, thereby locking and limiting the worm gear to prevent loosening.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] A sound-absorbing composite panel wall fixing device with a hidden buckle includes a base 1 and a movable seat 2. The base 1 is pre-fixed to the wall by bolts. A pair of side plate seats 101 are integrally formed on the front side of the base 1. The inner bottom of the side plate seats 101 is provided with a sliding groove 1012. The bottom sides of the movable seat 2 are integrally formed with sliders 204. The sliders 204 on both sides of the movable seat 2 are slidably connected to the sliding grooves 1012 on the inner side of the side plate seats 101, so that the movable seat 2 can slide back and forth under the guidance of the sliding grooves 1012.

[0021] The front side of the movable seat 2 is integrally formed with a fastening frame 201, and the fastening frame 201 has a fastening slot 2011. Fasteners are installed on the back of the sound-absorbing composite panel, and the fasteners are engaged in the fastening slot 2011 on the fastening frame 201, so that the sound-absorbing composite panel and the movable seat 2 can be fastened together. The side plate seat 101 has a rack groove 1011. The middle of the movable seat 2 is rotatably connected to a worm gear 202. Both ends of the rotating shaft connected to the worm gear 202 are provided with traveling gears 2021, and the traveling gears 2021 are meshed with the rack of the rack groove 1011. A worm 203 is rotatably connected to the movable seat 2 on one side of the worm gear 202, and the worm 203 is meshed with the worm gear 202. An inner shaft core 2031 with coaxial arrangement is connected in the worm 203. The upper end of the inner shaft core 2031 is provided with an internal hexagonal wrench head 2032. By inserting a long bolt cutter into the hexagonal wrench 2032 at the upper end of the worm gear 203 along the gap between the sound-absorbing composite panel and the wall, the worm gear 203 can be rotated and driven. The worm gear 203 meshes with the worm wheel 202, which in turn meshes with the rack groove 1011 on the side plate seat 101. This allows the movable seat 2 to slide back and forth along the guide of the slide groove 1012, thereby adjusting the gap between the sound-absorbing composite panel and the wall.

[0022] The technical solutions described in the above embodiments of this application have at least the following technical effects or advantages: This utility model uses a long bolt cutter to insert the internal hexagonal wrench 2032 at the upper end of the worm gear 203 along the gap between the sound-absorbing composite panel and the wall, thereby driving the worm gear 203 to rotate. The worm gear 203 meshes with the worm wheel 202, which in turn meshes with the rack groove 1011 on the side plate seat 101. This allows the movable seat 2 to slide back and forth along the guide of the slide groove 1012, thereby adjusting the gap between the sound-absorbing composite panel and the wall and facilitating the adjustment of the flatness of the sound-absorbing composite panel.

[0023] Example 2

[0024] The inner shaft core 2031 is a splined shaft. The inner shaft core 2031 is slidably connected to the middle of the worm gear 203. The inner shaft core 2031 extends through the bottom end of the worm gear 203. The bottom end of the inner shaft core 2031 is connected to a movable limiting plate 2051. The bottom of the movable seat 2 is provided with a fixed limiting ring 205 corresponding to the position of the movable limiting plate 2051. The top of the movable limiting plate 2051 is provided with an annular limiting sawtooth. The bottom of the fixed limiting ring 205 is provided with an annular limiting sawtooth groove that cooperates with the annular limiting sawtooth. A return spring 2052 is connected between the fixed limiting ring 205 and the movable limiting plate 2051. The return spring 2052 is sleeved on the outside of the inner shaft core 2031. Before rotating the worm gear 203, connect the hexagonal wrench 2032 with a bolt cutter and apply downward pressure to press the inner shaft core 2031 downward until the annular limiting teeth of the movable limiting plate 2051 at the bottom of the inner shaft core 2031 disengage from the annular limiting tooth groove of the fixed limiting ring 205. At this point, the worm gear 203 can be rotated. After adjusting the movable seat 2 to the appropriate position, release the pressure on the inner shaft core 2031. The inner shaft core 2031 will spring back upward under the action of the return spring 2052 until the annular limiting teeth of the movable limiting plate 2051 at the bottom of the inner shaft core 2031 re-engage with the annular limiting tooth groove of the fixed limiting ring 205, thereby locking and limiting the worm gear 203 to prevent loosening.

[0025] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: After the movable seat 2 is adjusted to a suitable position, the pressure on the inner shaft core 2031 is released. Under the action of the return spring 2052, the inner shaft core 2031 rebounds upward until the annular limiting sawtooth of the movable limiting disk 2051 at the bottom of the inner shaft core 2031 re-engages with the annular limiting sawtooth groove of the fixed limiting ring 205, thereby locking and limiting the worm gear 203 to prevent loosening.
