Therefore, it does not meet the existing needs. We propose a noise coefficient meter with a wire harness arrangement mechanism. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figure 1 and Figure 2 As shown, a noise coefficient meter with a harness tidying mechanism is shown, a plurality of fixing blocks 5 are fixed on both sides of the rear end of the instrument body 1, a plug-in block 6 is detachably installed on one end of the fixing block 5, a plurality of linearly distributed harness clamps 7 are installed between two horizontally adjacent plug-in blocks 6, the middle of the harness clamp 7 is circularly bent and the two ends are vertically upward, and the two ends of the harness clamp 7 remain parallel, and a flexible elastic connecting rod 8 is fixed to the outer side of the two ends of the harness clamp 7, the harness clamp 7 and the adjacent harness clamp 7 or the plug-in block 6 are fixedly connected by the flexible elastic connecting rod 8, the harness is inserted from the two ends of the harness clamp 7, so that the harness is clamped on the inner side of the circularly bent part of the harness clamp 7, the harness is fixed, the adjacent harnesses are isolated, so that the adjacent harnesses will not be entangled with each other, it is convenient for the staff to directly distinguish the harnesses, and it is convenient for the staff to plug or unplug the harnesses, thereby improving the operating efficiency of the staff.

[0021] A rubber gasket 9 is bonded to the inner side of the wire harness clamp 7. The spacing between the two ends of the wire harness clamp 7 is smaller than the diameter of the wire harness. The rubber gasket 9 is used to increase the friction between the wire harness and the wire harness clamp 7 so that the wire harness will not separate from the wire harness clamp 7 without human intervention.

[0022] like Figure 1 As shown, connecting shafts 4 are rotatably plugged on both sides of the instrument body 1, and rotating connecting rods 2 are fixed to the outer ends of the two connecting shafts 4. A hand-held rod 3 is fixed between the top ends of the two rotating connecting rods 2. The hand-held rod 3 is a plastic rod and a plurality of arc grooves are opened on the bottom surface. The width of the arc groove is larger than the width of an adult's finger. The edges of the arc groove are chamfered to facilitate the staff to grab the hand-held rod 3, so that the staff can pick up and transfer the instrument.

[0023] like Figure 1 and Figure 3As shown, the end where the fixed block 5 is connected to the plug-in block 6 is provided with a docking groove 10, and the end where the plug-in block 6 is connected to the fixed block 5 is installed with a pressure plate 11 and an anti-dropping plug-in plate 12, one end of the pressure plate 11 and the anti-dropping plug-in plate 12 is plugged into the inner side of the instrument body 1 and the anti-dropping plug-in plate 12 is fixed to the plug-in block 6, one end of the pressure plate 11 is plugged into the end of the plug-in block 6 and a pressure spring 15 is installed between the bottom end and the plug-in block 6, and the pressure spring 15 The two ends are respectively fixed to the plug-in block 6 and the pressure plate 11, and an anti-dropping slot 13 is provided on the bottom surface of the docking groove 10. An anti-dropping clamping block 14 is fixed to the bottom surface of the anti-dropping plug-in plate 12, and the anti-dropping clamping block 14 is clamped in the anti-dropping slot 13. By clamping the anti-dropping clamping block 14 in the anti-dropping slot 13, the connection strength between the anti-dropping plug-in plate 12, the plug-in block 6 and the fixed block 5 can be increased, so that the plug-in block 6 and the fixed block 5 cannot be easily separated after connection.

[0024] Working principle: First, press the pressure plate 11 toward the anti-dropout plug-in plate 12 to compress the pressure spring 15, and then plug the pressure plate 11 and the anti-dropout plug-in plate 12 into the docking groove 10 until the end face of the plug-in block 6 fits with the fixed block 5. At this time, the anti-dropout clamping block 14 on the bottom surface of the anti-dropout plug-in plate 12 will be clamped in the anti-dropout clamping groove 13. At the same time, the pressure spring 15 elastically recovers and presses the pressure plate 11 on the top surface of the docking groove 10, so that the plug-in block 6 and the fixed block 5 cannot be easily separated after being connected. Next, the staff only needs to press the end of the wire harness into the inner side of the wire harness clamp 7 from between the two ends of the wire harness clamp 7. The wire harness enters the wire harness clamp When the wire harness is between the two ends of the plate 7, the end of the wire harness clamp 7 will expand outward and make the flexible elastic connecting rod 8 bend elastically until the wire harness is clamped into the inner side of the rubber gasket 9. At this time, the flexible elastic connecting rod 8 elastically recovers and resets the end of the wire harness clamp 7. At this time, the wire harness will be clamped on the wire harness clamp 7 and the rubber gasket 9 for fixation. Finally, the staff can dock the end of the wire harness with the instrument body 1 to fix the wire harness and isolate adjacent wire harnesses so that adjacent wire harnesses will not be entangled with each other, which is convenient for the staff to directly distinguish the wire harnesses, plug or unplug the wire harnesses, and improve the operating efficiency of the staff.
