Description

Technical Field

[0001] This utility model relates to the field of sound insulation testing technology for composite microcrystalline sound insulation materials, and more specifically, to a dynamic and static joint testing system for multilayer composite microcrystalline sound insulation materials. Background Technology

[0002] With the rapid development of modern industry and transportation, noise pollution has become increasingly serious, leading to a growing demand for sound insulation materials. Multilayer composite microcrystalline sound insulation materials have attracted widespread attention and application due to their unique microstructure and excellent sound insulation performance. However, to accurately evaluate the sound insulation effect of this material in a real environment, it is necessary to consider its performance under both static and dynamic conditions.

[0003] Currently, most existing sound insulation material testing systems can only perform static or dynamic tests individually, failing to simultaneously simulate the static and dynamic environments faced by materials in actual use. This results in test results that cannot comprehensively and accurately reflect the material's sound insulation performance. For example, in some building and transportation applications, sound insulation materials must not only effectively block steady-state noise in static environments but also maintain good sound insulation performance under dynamic conditions, such as when subjected to external forces like vibration and impact. Therefore, there is an urgent need for a system capable of jointly testing multilayer composite microcrystalline sound insulation materials both dynamically and statically to meet the needs of practical applications. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a dynamic and static joint testing system for multilayer composite microcrystalline sound insulation materials to solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] A dynamic and static joint testing system for multilayer composite microcrystalline sound insulation materials includes a base, two vertical rods fixedly installed on the top of the base, a movable frame slidably installed between the outer sides of the two vertical rods, a sound insulation chamber fixedly installed inside the movable frame, a chamber cover hinged to the top of the sound insulation chamber, a clamping component installed on the chamber cover, a square rubber ring fixedly installed inside the sound insulation chamber, a composite microcrystalline box inside the square rubber ring, a noise generator fixedly connected inside the sound insulation chamber, a noise detection sensor fixedly installed on the inner wall of the sound insulation chamber, and a driving component installed between the base and the movable frame.

[0007] As a further description of the above technical solution: the clamping component includes a threaded rod and a rubber pressure plate. The bottom end of the threaded rod passes through and is threaded to the bottom of the bin cover and is rotatably connected to the rubber pressure plate. The bottom of the rubber pressure plate is in contact with the bin cover.

[0008] As a further description of the above technical solution: a cylinder is hinged to the bottom of the movable frame, and the bottom end of the cylinder is hinged to the left side of the top of the compartment cover.

The drive motor is fixedly mounted on the base, and the output end of the drive motor is fixedly connected to the crankshaft through a coupling. The crankshaft is rotatably mounted on the base. The top end of the connecting rod is hinged to the movable frame, and the bottom end of the connecting rod is rotatably connected to the crankshaft.

[0010] As a further description of the above technical solution: the top of the base is fixedly connected to two diagonal braces, and the other end of each of the two diagonal braces is slidably connected to the movable frame.

[0011] As a further description of the above technical solution: two springs are sleeved on the vertical rod, and the opposite ends of the two springs are respectively fixedly connected to the top and bottom of the movable frame.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Please see Figures 1-4 In this utility model, the dynamic and static joint testing system for multilayer composite microcrystalline sound insulation material includes a base 1, two vertical rods 2 fixedly installed on the top of the base 1, a movable frame 3 slidably installed between the outer sides of the two vertical rods 2, a sound insulation chamber 4 fixedly installed inside the movable frame 3, a chamber cover 5 hinged to the top of the sound insulation chamber 4, a clamping component 6 installed on the chamber cover 5, a square rubber ring 7 fixedly installed inside the sound insulation chamber 4, a composite microcrystalline box 8 inside the square rubber ring 7, a noise generator 9 fixedly connected inside the sound insulation chamber 4, a noise detection sensor 10 fixedly installed on the inner wall of the sound insulation chamber 4, and a driving component 11 installed between the base 1 and the movable frame 3.

[0022] In this invention, the base 1 serves as the support for the device. During use, the chamber cover 5 is opened, and the composite microcrystalline box 8 is placed inside the soundproof chamber 4 with its bottom opening facing upwards. It is then inserted into the square rubber ring 7. The chamber cover 5 is then closed, and the clamping component 6 is tightened to press the top of the composite microcrystalline box 8. The noise generator 9 is placed inside the composite microcrystalline box 8 to isolate it from the inside of the soundproof chamber 4. The noise generator 9 is then activated to generate noise, and the internal noise detection sensor 10 detects noise from the outside of the composite microcrystalline box 8, achieving static detection. The drive component 11 is then activated to drive the movable frame 3 to vibrate vertically along the vertical rod 2, simulating a dynamic environment. This allows for combined dynamic and static testing, resulting in a device that combines dynamic and static testing, has a compact structure, and is easy to operate. This solves the problem that existing soundproofing material testing systems can only perform static or dynamic tests individually, failing to simultaneously simulate the static and dynamic environments faced by materials in actual use, leading to test results that do not fully and accurately reflect the soundproofing performance of the material.

[0023] Please see Figure 1 The clamping component 6 includes a threaded rod 61 and a rubber pressure plate 62. The bottom end of the threaded rod 61 passes through and is threaded to the bottom of the bin cover 5 and is rotatably connected to the rubber pressure plate 62. The bottom of the rubber pressure plate 62 is in contact with the bin cover 5.

[0024] In this invention, rotating the threaded rod 61 causes the rubber pressure plate 62 to descend and contact the composite microcrystalline box 8, pressing it tightly so that it is in close contact with the square rubber ring 7 for sealing.

[0025] Please see Figure 1 Among them, the bottom of the movable frame 3 is hinged with a cylinder 31, and the bottom end of the cylinder 31 is hinged to the left side of the top of the cover 5.

[0026] In this invention, the cylinder 31 is tilted to push the cover 5 and the soundproof chamber 4 to close tightly, ensuring a sealing effect.

[0027] Please see Figure 2 The drive component 11 includes a drive motor 111, a crankshaft 112, and a connecting rod 113. The drive motor 111 is fixedly mounted on the base 1. The output end of the drive motor 111 is fixedly connected to the crankshaft 112 through a coupling. The crankshaft 112 is rotatably mounted on the base 1. The top end of the connecting rod 113 is hinged to the movable frame 3, and the bottom end of the connecting rod 113 is rotatably connected to the crankshaft 112.

[0028] In this invention, the crankshaft 112 is rotated by the drive motor 111, which in turn drives the connecting rod 113 to push the movable frame 3 to vibrate vertically on the vertical rod 2, thereby simulating a dynamic effect.

[0029] Please see Figure 1 The base 1 has two diagonal braces 12 fixedly connected to its top, and the other ends of the two diagonal braces 12 are slidably connected to the movable frame 3.

[0030] In this invention, the movable frame 3 is supported by the diagonal brace 12, making its vertical reciprocating operation more stable and the dynamic simulation effect better.

[0031] Please see Figure 1 Two springs 21 are fitted on the vertical rod 2, and the opposite ends of the two springs 21 are fixedly connected to the top and bottom of the movable frame 3, respectively.

[0032] In this invention, two springs 21 provide elastic support for the movable frame 3, resulting in less resistance and a more stable support effect as it runs on the vertical rod 2.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
