[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] Please refer to Figures 1-4. This utility model provides a technical solution: a test device for the sealing and sound insulation performance of fireproof doors and windows, including a test chamber 1 and a fixing mechanism 3. A test door 2 is installed inside the test chamber 1, a fixing mechanism 3 is set inside the test chamber 1, and a test mechanism 4 is set inside the test chamber 1.

[0021] The fixing mechanism 3 includes an installation groove 301, a movable groove 302, a first sealing strip 303, a second sealing strip 304, a limiting block 305, a spring 306, a connecting rod 307, and a pull ring 308. The installation groove 301 and the movable groove 302 are both located inside the test chamber 1. The first sealing strip 303 is bonded to the top surface of the test chamber 1. The second sealing strip 304 is installed inside the installation groove 301. The limiting block 305 is fitted inside the movable groove 302. A spring 306 is fixedly connected to one end of the limiting block 305, a connecting rod 307 is fixedly connected to one end of the limiting block 305, and a pull ring 308 is fixedly connected to one end of the connecting rod 307. The mechanism works via the installation groove 301, the movable groove 302, the first sealing strip 303, the second sealing strip 304, the limiting block 305, the spring 306, and the connecting rod 307. The connection rod 307 and pull ring 308 are configured so that when the test door 2 needs to be installed and fixed, the pull ring 308 is pulled. At this time, the pull ring 308 drives the limiting block 305 to move into the movable groove 302 through the connecting rod 307. The spring 306 is compressed and deformed. When the limiting block 305 is fully engaged in the movable groove 302, the test door 2 can be engaged in the mounting groove 301 through the mounting groove 301. Then, the force applied to the pull ring 308 is released. At this time, the spring 306 rebounds and deforms. The rebounding spring 306 drives the limiting block 305 to move back to its original position, so that the limiting block 305 fixes the test door 2 in place inside the test chamber 1. At the same time, due to the setting of the first sealing strip 303 and the second sealing strip 304, the test door 2 is sealed and installed inside the test chamber 1.

[0022] Furthermore, two sets of first sealing strips 303 are provided. The first sealing strips 303 are installed on both sides of the mounting groove 301. The first sealing strips 303 are made of rubber, and the second sealing strips 304 are made of rubber. Through the setting of the first sealing strips 303 and the second sealing strips 304, the first sealing strips 303 and the second sealing strips 304 can seal the test door 2 and the test chamber 1 during use.

[0023] Furthermore, the test door 2 is fitted inside the mounting groove 301, and the cross-sectional dimensions of the limiting block 305 match the cross-sectional dimensions of the movable groove 302. Through the setting of the limiting block 305, the limiting block 305 can install and fix the test door 2 inside the test chamber 1 during use.

[0024] Furthermore, two sets of springs 306 are provided. Springs 306 are located inside the movable groove 302. One end of spring 306 is fixedly connected to the test chamber 1. Through the setting of spring 306, when in use, the spring 306 rebounds and deforms, which can drive the limit block 305 to return to its original position, thereby allowing the limit block 305 to install and fix the test door 2 inside the test chamber 1.

[0025] Furthermore, the testing mechanism 4 includes a door 401, a noise generator 402, a power bank 403, a sealing groove 404, a mounting base 405, a third sealing strip 406, a fitting groove 407, a mounting block 408, and a decibel meter 409. One end of the testing chamber 1 is hinged to the door 401. The noise generator 402 and the power bank 403 are installed inside the testing chamber 1. A sealing groove 404 is formed on one end of the surface of the testing chamber 1. The mounting base 405 is fixedly connected to the top surface inside the testing chamber 1. The third sealing strip 406 is connected inside the sealing groove 404. A fitting groove 407 is formed inside the mounting base 405. A mounting block 408 is fitted inside the fitting groove 407. One end of the mounting block 408 is fixedly connected to the decibel meter 409. The testing mechanism 4, through the door 401, noise generator 402, power bank 403, sealing groove 404, and mounting base 405, allows for the connection of the door 401, noise generator 402, power bank 403, sealing groove 404, and mounting base 405. The base 405, third sealing strip 406, fitting groove 407, mounting block 408, and decibel meter 409 are configured as follows: After the test door 2 is installed and fixed, the decibel meter 409 is installed inside the test chamber 1. At this time, the mounting block 408, which is fixedly connected to one end of the decibel meter 409, can be installed inside the mounting base 405 through the fitting groove 407. Then, the chamber door 401 is closed. At this time, the chamber door 401 can prevent external noise from affecting the test results. Then, the power bank 403 is turned on. At this time, the power bank 403 supplies power to the noise generator 402, which works. The noise generator 402 generates noise, which is then detected by the decibel meter 409 to understand the sound insulation effect of the test door 2. The third sealing strip 406 installed inside the sealing groove 404 can prevent external noise from affecting the detection effect of the decibel meter 409.

[0026] Furthermore, the power bank 403 is electrically connected to the noise generator 402, and the third sealing strip 406 is made of rubber. Through the setting of the power bank 403, the power bank 403 can supply power to the noise generator 402 to enable the noise generator 402 to operate during use.

[0027] Furthermore, the noise generator 402 is located at the end away from the door 401, and the decibel meter 409 is located at the end close to the door 401. By setting the decibel meter 409, the noise can be monitored during use, thereby understanding the sound insulation effect of the test door 2.

[0028] Working principle: Pulling the pull ring 308 causes the pull ring 308 to move the limiting block 305 into the movable groove 302 via the connecting rod 307. The spring 306 compresses and deforms. When the limiting block 305 is fully engaged in the movable groove 302, the test door 2 can be engaged in the mounting groove 301. Then, releasing the force applied to the pull ring 308 causes the spring 306 to rebound, moving the limiting block 305 back to its original position. Thus, the limiting block 305 fixes the test door 2 inside the test chamber 1. Simultaneously, due to the first sealing strip 303 and the second sealing strip 304, the test door 2 is sealed inside the test chamber 1. 2. After installation and fixation, install the decibel meter 409 inside the test chamber 1. At this time, the mounting block 408, which is fixedly connected to one end of the decibel meter 409, can be installed inside the mounting base 405 through the fitting groove 407. Then close the chamber door 401. At this time, the chamber door 401 can prevent external noise from affecting the test results. Then turn on the power bank 403. At this time, the power bank 403 supplies power to the noise generator 402, making the noise generator 402 work. At this time, the noise generator 402 works and generates noise, so the decibel meter 409 detects the noise, thereby understanding the sound insulation effect of the test door 2. The third sealing strip 406 installed inside the sealing groove 404 can prevent external noise from affecting the detection effect of the decibel meter 409.
