Description

Technical Field

[0001] The utility model relates to the technical field of noise monitoring, in particular to an environmental noise monitor. Background Art

[0002] Noise is a widespread problem that can be encountered in a variety of environments, including homes, workplaces, transportation, and natural environments. Noise control and reduction are essential to protecting people's health and improving quality of life. A noise monitor is a device used to measure and record ambient noise levels. It can help assess the extent of noise pollution, monitor noise changes, and provide data support for noise control and governance.

[0003] Existing noise monitors are usually fixed to the wall by bolts to monitor the noise in the environment or room. However, the bolt fixing method makes it inconvenient to disassemble and install the noise monitor, and it is not convenient to adapt to the environmental noise monitoring needs in different scenarios, which easily affects the convenience of using the equipment.

[0004] Therefore, it is necessary to design an environmental noise monitor that can clamp and fix the placement frame, facilitate the portable monitor to be placed in different scenes for use, facilitate the disassembly and installation of the placement frame, and improve the convenience of use. Utility Model Content

[0005] In order to overcome the shortcomings of existing noise monitors that are inconvenient to disassemble and install due to the use of bolts, are inconvenient to adapt to environmental noise monitoring needs in different scenarios, and easily affect the convenience of equipment use, the utility model provides an environmental noise monitor that can clamp and fix a placement stand, is convenient for carrying the monitor and placing it in different scenarios, is convenient for disassembly and installation of the placement stand, and improves the convenience of use.

[0006] The technical implementation scheme of the utility model is: an environmental noise monitor, including a supporting frame, a connecting frame, a placing frame, a monitoring instrument, a fixing mechanism and a limiting mechanism, a plurality of supporting frames are rotatably connected to the connecting frame, a placing frame is clamped on the connecting frame, a monitoring instrument is placed on the placing frame, a fixing mechanism for fixing the monitoring instrument is provided on the monitoring instrument, and a limiting mechanism for fixing the placing frame is provided on the connecting frame.

[0007] As an improvement to the above solution, a shielding plate is also included, and the shielding plate is rotatably connected to the upper side of the rear portion of the placement rack.

[0008] As an improvement of the above-mentioned scheme, the fixing mechanism includes a fixing rod, a pressing rod, a first telescopic spring and a limiting ball. The left and right parts of the monitor are connected to the fixing rods, and the fixing rods are in contact with the placement rack. The fixing rods are slidably connected to the pressing rods, and the pressing rods are connected to the adjacent fixing rods with a first telescopic spring. Two upper and lower limiting balls are placed on the rear of the fixing rods, and the limiting balls are in contact with the pressing rods, and the limiting balls are in contact with the placement rack.

[0009] As an improvement of the above scheme, the limiting mechanism includes a guide rod, a limiting frame, a second telescopic spring, a pressing frame and a third telescopic spring. The guide rods are connected to the inner sides of the left and right parts of the connecting frame. The limiting frames are slidably connected to the guide rods. The limiting frames are slidably connected to the connecting frames. The second telescopic spring is connected between the limiting frames and the adjacent guide rods. The pressing frames are slidably connected to the left and right parts of the connecting frame. The pressing frames are in contact and cooperate with the limiting frames on the same side. The third telescopic spring is connected between the pressing frames and the connecting frames.

[0010] As an improvement of the above solution, the front part of the limiting frame is an inclined surface.

[0011] As an improvement of the above solution, the inner side of the limiting frame is arc-shaped.

[0012] The utility model has the following advantages: 1. The utility model pushes the pressing frame downward by hand to make the limiting frame move along the guide rod, and then inserts the placement frame into the connecting frame, and then releases the pressing frame, the pressing frame moves and resets to disengage from the limiting frame, and the limiting frame moves and resets, so that the placement frame can be clamped and fixed, which is convenient for carrying the monitor to be placed in different scenes for use, and is convenient for disassembly and installation of the placement frame, thereby improving the convenience of use.

[0013] 2. In the process of movement of the fixing rod of the utility model, the limiting ball moves inward at the same time, so that the pressing rod moves and the first telescopic spring is squeezed. When the fixing rod moves to the innermost part, the limiting ball on the lower side moves downward, the first telescopic spring rebounds, the limiting ball on the upper side moves upward, and the pressing rod moves and resets, so that the monitor can be fixed. The operation is simple and the disassembly and installation of the monitor is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
