Description

A device for testing the sound insulation performance of a glass interlayer. Technical Field

[0001] This utility model relates to the technical field of glass interlayer processing, specifically to a device for testing the sound insulation performance of glass interlayers. Background Technology

[0002] A glass interlayer is a special thin film material that is typically placed between two or more panes of glass and bonded together using a special process to form laminated glass. Sound insulation performance testing equipment is required during the processing of the glass interlayer.

[0003] The prior art discloses a PVB interlayer sound-insulating film (CN215243400U), which relates to the field of laminated glass technology. This utility model is a PVB interlayer sound-insulating film, comprising a glass body, a sound-insulating component movably disposed inside the glass body, and a disassembly component. The glass body includes a first glass body and a second glass body distributed on both sides of the sound-insulating component. The sound-insulating component includes a sound-insulating film body, an interlayer body, transparent sound-insulating cotton, and a transparent fiber sound-absorbing board. The interlayer body is movably disposed inside the sound-insulating film body. By providing the disassembly component, when the internal structure of the laminated glass is damaged or worn and needs replacement, the moving block is moved, causing it to stretch the elastic rod, thereby disassembling the moving block from the slot. When the interlayer body needs replacement, the moving block is squeezed to one side, causing it to disassemble from the slot, thus completing the disassembly of the interlayer body.

[0004] Current sound insulation performance testing devices cannot test sound insulation performance at different distances, and the surrounding environment is not sealed enough, which may lead to inaccurate test results. Summary of the Invention

[0005] The purpose of this invention is to provide a device for testing the sound insulation performance of a glass interlayer, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sound insulation performance testing device for a glass interlayer, comprising a testing chamber body, a support plate, and a fixing plate. A buzzer is installed at the bottom of the inner interior of the testing chamber body, and a controller is also installed at the bottom of the inner interior of the testing chamber body. The fixing plate is slidably connected to the bottom of the inner interior of the testing chamber body, and a connecting plate is movably inserted into the upper surface of the fixing plate. A slider is fixed to one outer end face of the fixing plate, and the slider is slidably connected to the bottom of the inner interior of the testing chamber body. A locking bolt is threadedly connected to the upper surface of the slider. The support plate is slidably connected to the inner wall of the testing chamber body, and a sliding plate is fixed to the upper surface of the support plate. A fixing bolt is threadedly connected to one outer end face of the sliding plate. A door is hinged to the front surface of the testing chamber body, and a handle is welded to the front surface of the door. A display screen is embedded and fixed to the front surface of the door.

[0007] When using the sound insulation performance testing device for a glass interlayer in this technical solution, the interlayer is fixed inside the testing chamber when testing is required. The buzzer is turned on and continuously emits sound. The decibel meter detects the volume of the sound and transmits a signal to the controller. The controller transmits a signal to the display screen, which displays the volume. The outer rod moves the inner rod under the action of the power device. The inner rod moves the base, which in turn moves the decibel meter, facilitating the testing of sound insulation performance at different distances.

[0008] Preferably, a slider is fixed to one outer end face of the fixing plate, and the slider is slidably connected to the inner bottom end of the detection box body. A locking bolt is threaded onto the upper surface of the slider. The slidable connection between the slider and the inner bottom end of the detection box body allows the fixing plate to be adjusted in the horizontal direction.

[0009] Preferably, a workbench is welded to the lower surface of the testing box body, and a support leg is welded to the lower surface of the workbench. The testing box body, the workbench, and the support leg are connected into a whole by welding, forming a sturdy frame structure.

[0010] Preferably, an outer rod is fixed to one outer end face of the testing box body, and an inner rod is movably inserted into one outer end face of the outer rod. Through this movable insertion, the inner rod can slide inside the outer rod, thereby achieving length adjustment. This design allows the testing box body to adjust its working range or operating distance according to actual needs.

[0011] Preferably, a base is fixed to one outer end face of the inner rod, and the base is slidably connected to the bottom inside the testing chamber body. A decibel meter is mounted on the upper surface of the base. The slidable connection of the base to the bottom inside the testing chamber body allows the position of the decibel meter to be flexibly adjusted according to testing requirements. This adjustability enables the device to adapt to different testing scenarios and layouts, improving its versatility and applicability.

[0012] Preferably, both the connecting plate and the fixing plate have internal fixing grooves, and a support rod is fixed to the inner wall of the fixing groove. The support rod is fixed in the fixing groove, which can effectively enhance the overall rigidity of the connecting plate and the fixing plate and prevent deformation under stress.

[0013] Preferably, a mounting rod is movably inserted into one outer end face of the support rod, and a clamping plate is fixed to one outer end face of the mounting rod. The length adjustment function of the mounting rod allows the position of the clamping plate to be flexibly adjusted, thereby better adapting to different installation scenarios.

[0014] Preferably, the lower surface of the support plate has a mounting groove, and a fixing rod is fixed to the inner wall of the mounting groove. The fixing rod can evenly distribute the force onto the support plate, reduce local stress concentration, and further improve the load-bearing capacity of the device.

[0015] Preferably, a connecting rod is movably inserted into one outer end face of the fixing rod, and a clamp is fixed to one outer end face of the connecting rod. The length adjustment function of the connecting rod allows the position of the clamp to be flexibly adjusted, thereby better adapting to different installation scenarios.

[0016] Preferably, the signal transmitter of the decibel meter is electrically connected to the signal receiver of the controller, and the signal transmitter of the controller is electrically connected to the signal receiver of the display screen. The decibel meter transmits the measured noise data to the controller in real time through the signal transmitter, and the controller then transmits this data to the display screen for display.
