Description

Technical Field

[0001] This utility model relates to the field of soundproof window technology, specifically a soundproof window for laboratory use. Background Technology

[0002] Acoustic laboratories typically consist of two complementary testing environments: an anechoic chamber and a reverberation chamber. These are often separated by a soundproof window to achieve both acoustic isolation and component sound insulation performance testing. Existing soundproof windows serve two purposes: firstly, to block noise transmission between the two laboratories, ensuring a clean testing environment; secondly, when component sound insulation testing is required, the original soundproof windows must be removed and replaced with a dedicated soundproof window structure fitted with the sample being tested.

[0003] Existing soundproof windows are bulky in actual use, and the disassembly and assembly process usually relies on large equipment such as forklifts and overhead cranes, which leads to inconvenience in operation, long replacement cycles, and high labor and time costs. In addition, the existing structure lacks effective modular design, making it difficult to achieve quick and flexible assembly and replacement, which limits its application in high-frequency and diverse testing scenarios.

[0004] Therefore, a soundproof window for laboratories is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a soundproof window for laboratory use to solve the problems mentioned in the background art.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] For an example, please refer to... Figure 1 , 2 1, 3, and 4, a laboratory soundproof window, comprising a door frame 1 and two infill panels.

[0030] The door frame 1 serves as the main supporting structure, with a through slot 3 inside. The slot 3 forms the channel for the entire soundproof window. Multiple mounting parts are distributed around the perimeter of the door frame 1. These mounting parts are used to fix the entire soundproof window to the reserved opening in the laboratory wall. Each mounting part is equipped with a set of sliding positioning parts. By operating the sliding positioning parts, the door frame 1 can be easily initially positioned and locked to the wall, simplifying the installation process.

[0031] Two infill plates are respectively installed on both sides of the slot 3 of the door frame 1, forming the sound insulation body together. Each infill plate has a positioning element at its end, that is, the edge that contacts the door frame 1. When the infill plate is placed on the corresponding side of the slot 3, the positioning element can be operated to make the infill plate firmly bonded to the door frame 1, ensuring acoustic sealing.

[0032] In a preferred embodiment, the mounting part specifically includes a plurality of cylindrical grooves 7 formed inside the door frame 1. Two adjacent cylindrical grooves 7 are connected by a sliding groove 5. A slidable positioning pin 8 is inserted into each cylindrical groove 7. A push piece 9 is fixedly connected to the side of the positioning pin 8. The push piece 9 passes through the sliding groove 5 and extends to the outside of the door frame 1, making it easy for the operator to push with their fingers.

[0033] During installation, after the door frame 1 is placed into the wall opening, the operator can push the pusher 9 to drive the positioning pin 8 to slide laterally in the cylindrical groove 7, so that its end extends out and presses against the wall, thereby achieving quick and tool-free initial fixation of the door frame 1.

[0034] Furthermore, grooves 6 are provided at both ends of the slide groove 5. These grooves 6 are used to provide a locking sensation when the push plate 9 slides to the end position, which can prevent the push plate 9 from sliding on its own due to accidental vibration, indicating that the positioning pin 8 has reached the fully retracted or fully extended working position.

[0035] To make the fixing of the filling plate more reliable, pin slots 13 are provided on the inner perimeter of the slot 3, that is, on the surface that mates with the filling plate, corresponding one-to-one with the positions of the positioning parts.

[0036] In this embodiment, one specific implementation of the positioning component includes a knob 10 fixedly installed on the surface of the filling plate. An installation groove 14 is provided inside the filling plate. One end of the knob 10 penetrates the wall of the filling plate and extends into the installation groove 14, and a pin 2 is fixedly connected to its end. By rotating the knob 10, the pin 2 can be rotated together. The shape of the pin 2 is designed so that when it rotates at a specific angle, it can be engaged or disengaged from the pin groove 13 on the door frame 1, thereby realizing the mechanical locking and releasing of the filling plate. This structure makes the installation and disassembly of the plate very convenient, and facilitates later maintenance or replacement.

[0037] Regarding the infill panels themselves, both panels include a steel plate 4, the size of which is adapted to the size of the slot 3 on the door frame 1 to ensure that the passage can be completely covered and sealed.

[0038] To achieve superior broadband sound insulation, the two infill panels employ different acoustic treatments. Specifically, one steel plate 4 has a glass wool layer 11 fixedly covered on its side, which has excellent sound absorption and insulation performance for mid-to-high frequency noise. The other steel plate 4 has a polyester fiber layer 12 fixedly covered on its side, which effectively improves the control of low-frequency noise. This dual heterogeneous filling layer design enables the soundproof window to cope with a wider noise spectrum, thereby improving the overall sound insulation performance.

[0039] Working principle overview: During installation, the door frame 1 is first fixed to the wall opening using sliding positioning parts. Then, two filling panels with different sound-absorbing materials are inserted from both sides of the slot 3. By rotating the knob 10, the pin 2 is rotated and locked into the pin groove 13, thus tightly fixing the filling panels to the door frame 1, forming a complete barrier with a multi-layered composite sound insulation structure. The entire installation process requires no complicated tools, is convenient and efficient, and ensures good sound sealing.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
