[0002] Faced with increasingly serious environmental pollution, people all over the country are beginning to re-examine and re-understand environmental issues. Noise pollution is one of the most influential environmental pollutions. Higher decibel noise can even cause serious damage to the human eardrum, leading to deafness, etc. The application of noise detectors can provide the decibels reached by the noise so as to take relevant measures to control and reduce the noise. It is mainly used for noise detection and testing instruments in work sites, squares and other public places.

[0003] There is an existing noise detection device that is easy to disassemble (Announcement No.: CN219368926U) but has the following defects: the above-mentioned device locks the display screen through the cooperation of a spring, a slider and a clamp ring, but when the above-mentioned locking mechanism is disassembled, both hands are needed to move the locking mechanism, which results in no one holding up the display screen. Once unlocked, the display screen will fall down, resulting in at least two workers required to continue each disassembly, which is troublesome to disassemble. In addition, the locking directions of the spring, the slider and the clamp ring are connected, which causes the display screen to be subjected to external force or squeeze the spring, causing the spring to deform and compress, thereby causing the display screen to shake easily. For this reason, the utility model is proposed. Utility Model Content

Three clamping strips 204 are fixed on the rear side of the display screen 102. Three clamping grooves 205 are opened on the front side of the connecting sleeve 2. The clamping strips 204 are slidably arranged inside the clamping grooves 205.

[0022] In an embodiment, two fixing plates 206 are fixed to the rear side of the display screen 102. Two toggle levers 202 are respectively rotatably connected to the two sides of the two fixing plates 206 that are away from each other. A connecting block 207 is fixed to the top surface of the toggle lever 202. A resilient rod 208 is rotatably connected to the top surface of the connecting block 207. Two support plates 209 are fixed to the rear side of the display screen 102. A resilient sleeve 210 is fixed to the bottom surface of the support plate 209. The resilient rod 208 is inserted into the inside of the resilient sleeve 210. A spring 211 is fixed between the top end of the resilient rod 208 and one side inside the resilient sleeve 210. Through the setting and use of the toggle lever 202, by pulling the toggle lever 202 with both hands, the toggle lever 202 rotates upward, so that the locking rod 203 disengages from the inside of the locking groove 201. At this time, by continuing to lift the toggle lever 202, the clamping strip 204 can be withdrawn from the inside of the clamping groove 205. Subsequently, the display screen 102 can be removed from the connecting sleeve 2, completing the disassembly. The disassembly can be completed during the process of lifting the display screen 102, so that the disassembly process only requires a single person to operate with both hands, making the disassembly convenient and fast. Moreover, the cooperation of the locking rod 203 and the clamping strip 204 can effectively prevent the display screen 102 from shaking due to external forces, increasing the stability of the installation of the display screen 102.

[0023] In an embodiment, two first limiting plates 3 and two second limiting plates 301 are fixed to the rear side of the display screen 102. The first limiting plates 3 and the second limiting plates 301 are in corresponding positions. The first limiting plates 3 and the second limiting plates 301 are respectively located above and below the toggle lever 202. Through the setting and use of the first limiting plates 3 and the second limiting plates 301, the toggle lever 202 can be limited and supported.

Through the arrangement and use of the universal wheels 6 , it is convenient for the staff to better move the noise detection equipment to the working point.

[0027] Working principle: When in use, the device can be moved to the working point by pushing the sliding rod 101 to cooperate with the universal wheel 6, and then the universal wheel 6 is locked. At this time, the bolt 401 is taken out from the inside of the fixing hole 4 and the threaded hole 402 to adjust the height of the connecting sleeve 2 and the display screen 102. Then, the bolt 401 is installed to perform noise detection. When the display screen 102 needs to be disassembled, the staff walks to the front of the display screen 102, and then holds the gripping handle 5 with both hands and pulls it upward, so that the toggle rod 202 rotates upward, and the lock is The fixed rod 203 disengages from the interior of the locking groove 201, and as the toggle rod 202 rotates upward, the rebound rod 208 contracts toward the interior of the rebound sleeve 210 and compresses the spring 211, and then the toggle rod 202 fits against the bottom surface of the second limit plate 301. At this time, the toggle rod 202 is continued to be pulled to move the display screen 102 upward as a whole, and the snap-in strip 204 is pulled out from the interior of the snap-in groove 205. At this time, the display screen 102 is disengaged from the connecting sleeve 2, thereby completing the disassembly and can begin maintenance. When installing, the above process can be reversed.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
