Technical Field

[0001] The utility model relates to the technical field of sound insulation detection, in particular to a sound insulation detection device for construction engineering. Background Art

[0002] With the development of the construction industry, people have higher and higher requirements for sound insulation materials, including sound insulation glass, floor slabs, etc. Before the sound insulation glass is put into use, it needs to be tested for sound insulation to check whether it meets the use requirements, so it is necessary to use a sound insulation detection device.

[0003] The existing Chinese patent with patent announcement number "CN213022986U" announced "A building glass sound insulation detection device". Sound insulation silicone blocks are provided in the inner walls of the test box and the box cover to ensure the sound insulation of the test environment. At the same time, the box cover is pressed against the test box through the interaction of the screw rod and the fixed arm. Since the sound insulation silicone block wraps the outer wall of the test box, the reliability of the test result can be guaranteed.

[0004] However, in the above patent, when testing the glass, the glass is placed on a sound-insulating silicone block and pressed against the test box by a box cover, so as to perform sound insulation detection on the glass. However, the box cover cannot press on the glass. When the device performs sound insulation detection on the glass, if the device shakes due to external factors, the glass will shake on the sound-insulating silicone block, resulting in inaccurate data detected by the decibel meter. Therefore, we propose a construction engineering sound insulation detection device to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0025] In one embodiment, Figure 1-Figure 5 As shown, a construction engineering sound insulation detection device comprises: a workbench 1 and a detection box 2, wherein the detection box 2 is arranged on the upper end surface of the workbench 1; a box cover 3, which is arranged above the detection box 2; a detection component, which is used to press the glass placed inside the detection box 2, and the detection component is arranged inside the box cover 3;

[0026] The detection component includes a first sound insulation member 4, which is arranged on the upper inner wall of the box cover 3, and a second storage groove 24 is arranged on the first sound insulation member 4, and two groups of fixing blocks 5 are arranged on the upper inner wall of the second storage groove 24, and the two groups of fixing blocks 5 are fixedly penetrated with fixing rods 6, and the outer side of the fixing rods 6 is sleeved with two groups of fixing sleeves 7, and the two groups of fixing sleeves 7 are hingedly connected with two groups of connecting rods 8, and the other ends of the multiple groups of connecting rods 8 are hingedly connected with a group of sliding blocks 9, and the multiple groups of sliding The blocks 9 are all slidably sleeved on the outer wall of a group of sliding rods 10, and the multiple groups of sliding rods 10 are respectively arranged on the inner wall of a group of grooves 11, and the multiple groups of grooves 11 are respectively arranged on the upper end surfaces of the two groups of pressing rods 12; a second sound insulation member 23 is arranged on the inner wall of the detection box 2, and a first storage groove 13 is opened on the second sound insulation member 23, and a sound generating device 14 is arranged on the inner wall of the bottom end of the first storage groove 13; a decibel detector 15 is installed on the inner wall of the upper end of the second storage groove 24;

[0027] Specifically, when in use, the glass to be tested is placed on the upper end surface of the second sound insulation member 23 inside the test box 2, and then the drive motor 19 is started. The drive motor 19 drives the threaded rod 18 to rotate, and the threaded rod 18 drives the threaded sleeve 17 to move downward with the cooperation of the limit rod 21, so that the box cover 3 moves downward. When the box cover 3 moves downward to cover the outside of the test box 2, the two groups of pressing rods 12 move downward at the same time to press on the glass. At the same time, after the pressing rods 12 are pressed on the glass, they can slide on the sliding rods 10 through the multiple groups of sliding blocks 9, so that the multiple groups of connecting rods 8 move to both sides of the pressing rods 12, so that the box cover 3 can continue to move downward to the outside of the test box 2, so that the box cover 3 is more tightly sealed. The outside of the detection box 2 is detected, and then the sound-generating device 14 is started, and the decibel of the sound emitted by the sound-generating device 14 is detected by the decibel detector 15 inside the box cover 3; by setting the sound insulation component, the glass can be pressed by two sets of pressing rods 12, so that the glass is firmly pressed on the upper end of the second sound insulation component 23, so as to avoid the problem that when the device performs glass sound insulation detection, if the device shakes due to external factors, it will cause the glass to shake on the sound insulation silicone block, thereby causing the decibel meter to detect data inaccurately; at the same time, the box cover 3 can tightly cover the outside of the detection box 2, so that the glass is in a more sealed environment for sound insulation detection, thereby improving the accuracy of the glass sound insulation detection data.

[0028] like Figure 1-Figure 2 As shown, a group of lifting blocks 16 are arranged on the outer walls of both sides of the box cover 3, and a threaded sleeve 17 is arranged inside one group of lifting blocks 16, and a threaded rod 18 is arranged on the internal thread of the threaded sleeve 17, and the threaded rod 18 is connected to the output end of the driving motor 19, and the driving motor 19 is arranged on the upper end surface of the workbench 1; by arranging the lifting blocks 16, the threaded sleeve 17, the threaded rod 18 and the driving motor 19, the lifting blocks 16 can be driven to move up and down, thereby driving the box cover 3 to move up and down. A sliding sleeve 20 is arranged inside the other group of lifting blocks 16, and a limit rod 21 is arranged inside the sliding sleeve 20, and the lower end surface of the limit rod 21 is arranged on the upper end surface of the workbench 1; by arranging the sliding sleeve 20 and the limit rod 21, the lifting and lowering of the box cover 3 can be guided and limited, so that the box cover 3 can move up and down more stably. A set of limit blocks 22 are disposed on the upper end surfaces of the threaded rod 18 and the limit rod 21 ; the limit blocks 22 can limit the upper ends of the threaded rod 18 and the limit rod 21 .

[0029] The above embodiment discloses a sound insulation detection device for construction projects. When in use, the glass to be detected is placed on the upper end surface of the second sound insulation member 23 inside the detection box 2, and then the driving motor 19 is started. The driving motor 19 drives the threaded rod 18 to rotate, and the threaded rod 18 drives the threaded sleeve 17 to move downward with the cooperation of the limit rod 21, so that the box cover 3 moves downward. When the box cover 3 moves downward to cover the outside of the detection box 2, the two groups of pressing rods 12 move downward at the same time and press on the glass. At the same time, after the pressing rods 12 are pressed on the glass, they can slide on the sliding rods 10 through multiple groups of sliding blocks 9, so that the multiple groups of connecting rods 8 move to both sides of the pressing rods 12, so that the box cover 3 can continue to move downward to the outside of the detection box 2, so that the box cover 3 is more tightly sealed on the outside of the detection box 2, and then the sound-generating device 14 is started, and the decibel detector 15 inside the box cover 3 is used to detect the decibel of the sound emitted by the sound-generating device 14, which is relatively convenient.
