Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, and more specifically to an environmental noise detection device. Background Art

[0002] A noise detector is an instrument used to detect, measure, and record noise levels in an environment. It is widely used in environmental protection, industry, transportation, healthcare, construction, aviation, and aerospace to protect hearing and health, and optimize process and machine operations. However, current noise detector mounting fixtures require a long installation time and cannot be quickly disassembled or assembled when not needed for testing. This requires further improvement.

[0003] Chinese utility model patent application number CN219121546U discloses an environmental noise detection device, which includes a mounting assembly A and a mounting assembly B. The mounting assembly A and the mounting assembly B are mounted on a mounting rod, and the mounting assembly A and the mounting assembly B are connected to the main body of the environmental noise detection device via screw A. The mounting assembly A and the mounting assembly B have compatible structures, and the mounting assembly A and the mounting assembly B are symmetrically mounted at the rear end of the main body of the environmental noise detection device. The environmental noise detection device is installed and fixed to the environmental noise detection device body and the installation component A by inserting the connecting plate B into the connecting plate A. However, since there is no fixing device between the connecting plate B and the connecting plate A, the environmental noise detection device body may slide on the installation component A during use, thereby affecting the safety of the environmental noise detection device body when it is fixed. Moreover, the clamp is fixed on the pole, and the connecting plate B is located at the rear side of the environmental noise detection device body, which will affect the user's line of sight during installation and requires the user to tilt his head for observation, which makes it inconvenient for the user to insert the connecting plate B behind the environmental noise detection device body into the connecting plate A, which will extend the maintenance time.

[0004] Therefore, it is necessary to propose an environmental noise detection device to solve the above problems. Utility Model Content

A spring 120 is provided between the trigger sleeve 117 and the lower bracket 113.

[0031] refer to Figure 4 The cavity 104 is rotatably connected to a bidirectional threaded rod 121 extending to the outside of the fixed box 103. Through the symmetrical thread setting, the symmetrical moving rod 109 can be pushed to move in opposite directions, so that the fixing component 110 can be inserted into the circular hole 108. The two ends of the bidirectional threaded rod 121 are threadedly connected to the moving rod 109.

[0032] Specifically, refer to Figure 5 There is a rubber pad 122 in a circular array on the inner wall of the circular hole 108. When the card block 111 is extended, it will rest on the rubber pad 122. Through contact with the rubber pad 122, the plug-in block 107 is fixed. The position of the rubber pad 122 corresponds to the card block 111.

[0033] Specifically, refer to Figure 6 and Figure 7 The oblique groove 118 is arranged at one end close to the lower bracket 113 and is inclined toward the fixed rod 116 . The sliding rod 119 can drive the block 111 to move through the inclined setting of the oblique groove 118 .

[0034] Specifically, refer to Figure 4 Trigger plates 123 are provided at the upper and lower ends of the cavity 104 . The trigger plates 123 cooperate with the trigger sleeve 117 to limit the movement of the trigger sleeve 117 , thereby driving the card block 111 to move, and the trigger sleeve 117 can contact the trigger plate 123 .

[0035] Specifically, two or more clamps 101 are provided and axially arrayed on the fixing box 103. The plurality of clamps 101 can increase the stability of the noise detection device body 102 when it is fixed on the pole.

[0036] In this embodiment, the noise detection device body 102 is fixed to the wire rod by a clamp 101. A plurality of clamps 101 are provided and arrayed on the fixing box 103 to increase firmness. A mounting plate 106 is provided on one side of the noise detection device body 102. Plug-in blocks 107 are provided at the four corners of the mounting plate 106. The plug-in blocks 107 can be inserted into the square slots 105 and the bidirectional threaded rod 121 is rotated to complete the fixation of the noise detection device body 102 and the fixing box 103. The noise detection device body 102 then detects the nearby ambient noise.

[0037] When the plug-in block 107 is inserted into the square groove 105, the circular hole 108 and the fixing assembly 110 are on the same axis. At this time, the bidirectional threaded rod 121 is rotated, and the bidirectional threaded rod 121 drives the moving rods 109 at both ends to move through the threaded connection. At this time, the fixing assembly 110 is inserted into the circular hole 108. When the fixing assembly 110 continues to move, the trigger sleeve 117 will be against the trigger plate 123, thereby moving along the outer wall of the fixing rod 116 toward the lower bracket 113, triggering The spring 120 between the sleeve 117 and the lower bracket 113 will be compressed, and when the sleeve 117 is triggered to move, the sliding rod 119 will move together. The sliding rod 119 pushes the block 111 outward by moving in the oblique groove 118 to open. Then the block 111 comes into contact with the rubber pad 122 and squeezes it, so that the fixing assembly 110 can fix the plug-in block 107 from the inside of the circular hole 108, thereby completing the installation and fixation of the noise detection device body 102 and the fixing box 103;

[0038] When the block 111 moves, it moves along the guide rod 115 in the sliding slot 114;

[0039] When the noise detection device body 102 needs to be inspected and removed from the fixed box 103, first rotate the bidirectional threaded rod 121 in the opposite direction to make the symmetrical moving rod 109 move toward the middle, and the moving rod 109 drives the fixed assembly 110 to move. At this time, the spring 120 resets and pushes the trigger sleeve 117 to move toward the end away from the lower bracket 113. The trigger sleeve 117 is connected to the sliding rod 119 in the oblique groove 118 to pull the block 111 toward the fixed rod 116, thereby reducing the diameter of the fixed assembly 110, so that the fixed assembly 110 loses its fixing effect on the plug-in block 107, and then the noise detection device body 102 can be removed from the fixed box 103.
