[0002] Aluminum profiles are alloy materials with aluminum as the main component. Aluminum rods are melted and extruded to obtain aluminum materials with different cross-sectional shapes. However, the mechanical properties and application fields of the industrial aluminum profiles produced are different depending on the proportion of alloys added. However, aluminum is a metal with high density and high rigidity, but low sound insulation effect.

The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0015] Please see Figures 1 to 7 The present invention preferably provides the following technical solution: a sound-insulating aluminum profile, comprising: a rectangular frame 111, the rectangular frame 111 being a hollow structure with openings at both ends for forming a sound-insulating cavity; a slot structure symmetrically arranged on the upper and lower sides of the rectangular frame 111, damping plates 112 respectively assembled with the upper and lower surfaces of the slot structure; and sound-insulating layers 113 respectively assembled on the back side of the damping plates 112; and further comprising an outer casing for wrapping and assembling the rectangular frame 111, the damping plates 112 and the sound-insulating layers 113.

[0016] It is known that sound is a vibration and can be transmitted efficiently through rigidly connected components. In order to improve the sound insulation effect of aluminum profiles; Firstly, this application adopts a cavity structure, such as Figure 6 , 7 As shown, the rectangular frame 111 specifically provided in this application is a hollow structure with openings at both ends in the middle of the device to form a sound insulation cavity. This design reduces the weight of the device while the internal air layer can also play a certain role in damping and sound insulation. Secondly, the material properties of the damping plate 112 and the sound insulation layer 113 further improve the sound insulation effect of the device; Finally, the assembled outer casing can completely cover the rectangular frame 111, the damping plate 112, and the sound insulation layer 113 to seal the openings at both ends of the rectangular frame 111 and establish an airtight and sound insulation barrier.

[0017] Furthermore, each set of slot structures includes a number of triangular slot heads 123 arranged continuously and connected to the rectangular frame 111, wherein two adjacent triangular slot heads 123 and the rectangular frame 111 form a trapezoidal slot; furthermore, each damping plate 112 includes an assembly part connected to the sound insulation layer 113, and a trapezoidal block part that is limited and engaged with the trapezoidal slots one by one.

[0018] like Figure 4 , 6As shown in Figure 7, several sound insulation layers 113 are respectively arranged on the upper and lower sides of the rectangular frame 111 and are connected to it. The two adjacent sound insulation layers 113 on the left and right together with the rectangular frame 111 form a trapezoidal slot. The trapezoidal blocks where each damping plate 112 is located correspond one-to-one with the trapezoidal slot, such as... Figure 3 As shown, the assembly part is simultaneously assembled with the sound insulation layer 113 to achieve the assembly of the rectangular frame 111, the two damping plates 112 and the two sound insulation layers 113 from the inside out.

[0019] Furthermore, the damping plate 112 is made of polymer damping material.

[0020] like Figure 4 , 5 As shown in Figures 6 and 7, the polymer material of the damping plate 112 has damping properties, which can absorb some vibration energy and reduce resonance transmission.

[0021] Furthermore, the two sound insulation layers 113 are preferably a sound-absorbing panel and aluminum foam, respectively. The sound-absorbing panel is made of porous materials, such as inorganic fiber materials like rock wool and glass wool, which focus on mid-to-high frequency absorption and are commonly used as the filling layer of metal sound-absorbing panels. The aluminum foam matrix has uniformly distributed micro-bubbles with a porosity of 50% to 90% and a low density of 0.2 to 0.6 g / cm³. 3 It has a wide sound absorption bandwidth, which is especially effective for mid and low frequencies. It is also lightweight, weather-resistant, and conductive, thus achieving sound insulation.

[0022] Furthermore, the assembly jacket includes a sleeve 114 that wraps around the rectangular frame 111, the damping plate 112, and the sound insulation layer 113; and a plug-in structure for sealing and fixing both ends of the sleeve 114; further, the plug-in structure includes a first side plate 115, and clips 116 fixed at both ends of the first side plate 115, wherein each clip 116 is adapted to be plugged into two triangular clips 123 symmetrically distributed vertically; and a screw hole 120 opened at the end of each clip 116 away from the first side plate 115; and also includes a second side plate 117, with mounting holes 118 opened at both ends of the second side plate 117, each mounting hole 118 having a bolt 119, wherein when the first side plate 115 and the second side plate 117 are combined on both sides of the sleeve 114, the bolt 119 can be threadedly connected to the screw hole 120 one by one.

[0023] like Figure 4 , 5As shown in Figures 6 and 7, the first side plate 115 and the second side plate 117 move relative to each other. Two locking strips 116 and two sets of bolts 119 are respectively provided on their opposite surfaces. Each locking strip 116 is adapted to be inserted into two symmetrically distributed triangular locking heads 123 and has a screw hole 120 corresponding to a set of bolts 119. When the two locking strips 116 are placed inside the two sets of triangular locking heads 123 at the beginning and end, the bolts 119 are operated to merge the first side plate 115 and the second side plate 117 into the two sides of the sleeve 114, completing the assembly process and closing both ends of the rectangular frame 111.

[0024] Furthermore, sealing gaskets 122 are respectively provided on the opposite surfaces of the first side plate 115 and the second side plate 117, such as... Figure 5 As shown, when the first side plate 115 and the second side plate 117 are joined to both sides of the sleeve 114, two sealing gaskets 122 are used to seal the ends of the rectangular frame 111 to improve the sealing effect of the device. Here, the sealing gaskets 122 are preferably made of rubber.

For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.
