[0037] Applying the above suspension device for sound insulation box testing has at least the following beneficial effects: The buffer assembly 400 on the base 100 buffers and weakens the vibration conducted by the ground for the first time. At the same time, the sound insulation box is suspended on the frame assembly 200 through the rope fixing assembly 300 and the frame assembly 200, so that there is no contact between the lower end of the sound insulation box and the base 100, and the vibration conducted by the ground is buffered and weakened for the second time, greatly reducing the external interference to the sound insulation box and improving the accuracy of the test results.

[0038] According to some embodiments of the present utility model, the rope fixing assembly 300 includes a first clamping plate 310, a second clamping plate 320 and two connecting rods 330. The two ends of the first clamping plate 310 and the second clamping plate 320 are respectively connected to the two connecting rods 330. The first clamping plate 310 and the second clamping plate 320 cooperate to clamp the upper end of the suspension rope 230. Among them, the first clamping plate 310 and the second clamping plate 320 can both be fixed to the connecting rod 330, or one of them is fixed to the connecting rod 330, and the other can be movably arranged on the connecting rod 330, or both of them are movably arranged on the connecting rod 330. If both are fixed to the connecting rod 330, the rope fixing assembly 300 is only used to suspend the sound insulation box for secondary shock absorption. By movably arranging one of them on the connecting rod 330, it is convenient for the installation and disassembly of the suspension rope 230. By movably arranging both of them on the connecting rod 330, it is convenient for the installation of the suspension rope 230 and at the same time, the height of the suspended sound insulation box can be adjusted.

[0039] According to some embodiments of the present utility model, buffer slopes 321 are provided on both sides of the second clamping plate 320. Through the buffer slopes 321, the friction surface between the suspension rope 230 and the second clamping plate 320 is increased, so that the suspension rope 230 is more stably suspended on the second clamping plate 320, and at the same time, the situation that the suspension rope 230 is frequently rubbed by the corners of the second clamping plate 320 and breaks is avoided.

[0040] According to some embodiments of the present utility model, the connecting rod 330 is provided as a threaded rod, and the rope fixing assembly 300 further includes a plurality of nuts 340. The plurality of nuts 340 are threadedly connected to the connecting rod 330. At least one nut 340 is respectively arranged above the first clamping plate 310 and below the second clamping plate 320. In this embodiment, both the first clamping plate 310 and the second clamping plate 320 are movably connected to the connecting rod 330. By adjusting the position of the nut 340 below the second clamping plate 320 on the connecting rod 330, the height of the suspended sound insulation box is adjusted. By adjusting the nut 340 above the first clamping plate 310, the tightness of the fixed suspension rope 230 and the disassembly and assembly of the suspension rope 230 are adjusted.

[0041] According to some embodiments of the present utility model, there are four rope fixing assemblies 300, and the four rope fixing assemblies 300 are respectively arranged at the four corners of the first bracket 210. There are four suspension ropes 230. The four corners of the sound insulation box are suspended by the four rope fixing assemblies 300, and through the above embodiments, the heights of the four corners of the sound insulation box can be adjusted respectively, so that the sound insulation box can be leveled.

[0042] According to some embodiments of the present utility model, the buffer assembly 400 includes a support column 410, an elastic buffer 420, and a bottom plate 430. The support column 410 and the elastic buffer 420 are both disposed on the bottom plate 430. There are multiple support columns 410, and the multiple support columns 410 are evenly distributed on the circumferential side of the elastic buffer 420. The upper end of the support column 410 is connected to the base 100. The support column 410 plays an overall supporting role for the base 100. The elastic buffer 420 can reduce the vibration from the bottom plate 430, so that the vibration transmitted to the base 100 is reduced, thereby completing the first shock absorption.

[0043] According to some embodiments of the present utility model, the elastic buffer 420 is provided as a rubber part or a silica gel part.

[0044] According to some embodiments of the present utility model, a plurality of guide plates 500 are further provided on the base 100. The plurality of guide plates 500 are divided into two groups, and the two groups of guide plates 500 are distributed in parallel. The guide plates 500 are used to play a guiding role when loading the sound insulation box into the frame assembly 200, ensuring that the sound insulation box correctly enters the frame assembly 200 and completes hoisting.

[0045] According to some embodiments of the present utility model, a positioning rod 600 is also movably provided on the base 100. The positioning rod 600 is disposed between the two groups of guide plates 500. It also includes a driving member disposed in the base 100. The driving member is used to drive the positioning rod 600 to move up and down. When loading the sound insulation box into the frame assembly 200, under the action of the driving member, the positioning rod 600 moves down to make way, and during the test process, the positioning rod 600 is located in the base 100, so that the sound insulation box only maintains a suspended state. When it is necessary to position the sound insulation box, the driving member drives the positioning rod 600 to move up, so that the positioning rod 600 abuts against the corresponding structure at the lower end of the sound insulation box, thereby completing the positioning of the sound insulation box and avoiding shaking.
