Description

Technical Field

[0001] The utility model relates to the technical field of paint detection, in particular to a paint sound insulation detection box. Background Technique

[0002] A paint sound insulation detection box is a device specifically used for detecting the sound insulation performance of paints. Its main purpose is to simulate the actual environment and accurately and reliably test the sound insulation effect of the paint. Through this detection box, the performance of the paint in reducing noise can be evaluated, providing a scientific basis for the selection and application of the paint.

[0003] The existing sound insulation detection boxes have a high manufacturing cost and may vary depending on different manufacturers and uses. Specifically, the decibel sound insulation volume during the detection process cannot be measured. Therefore, those skilled in the art have provided a paint sound insulation detection box to solve the problems raised in the above background technique. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a paint sound insulation detection box, which includes a detection bottom box. The detection bottom box is internally provided with a sound insulation component. A vibration sensor is fixedly installed on the lower inner wall surface of the detection bottom box. A spring-sensitive corrugated part is arranged on the inner side of the vibration sensor. When the spring-sensitive corrugated part is subjected to sound wave vibration, it will make high-frequency contact with the vibration sensor, thereby recording corresponding numbers for evaluating the sound insulation effect of the measured paint.

[0005] Preferably, a sealed box cover is screwed on above the detection bottom box.

[0006] Preferably, a sealing rubber ring is fixedly clamped on the upper inner wall surface of the detection bottom box, so as to shock-absorb the sound insulation component through the sealing rubber ring.

[0007] Preferably, the sound insulation component includes a fixed seat, a power amplifier board, an expander, a paint sleeve part, a bolt seat and a fixing bolt. The power amplifier board is fixedly installed at the upper end of the fixed seat, and the expander is fixedly installed in the middle of the lower end of the fixed seat. The expander is arranged corresponding to the power amplifier board.

[0008] Preferably, a paint sleeve part is arranged below the fixed seat. Different test model paints are used for pre-coating on the inner and outer wall surfaces of the paint sleeve part.

[0009] Preferably, a bolt seat is fixedly installed on the upper part of the side end of the paint sleeve part. The paint sleeve part is covered on the expander by passing the fixing bolt through the bolt seat, so that the paint performs sound insulation treatment on the sound conduction of the expander.

[0010] Technical Effects and Advantages of the Utility Model

[0011] When the utility model is in use, multiple types of measurement coatings are respectively coated on multiple coating sleeve parts in advance. The coating sleeve parts are removed from the fixed seat by turning the fixing bolts out of the bolt seat, and the pre-made coating sleeve parts with coatings are replaced. The sound-absorbing component is placed on the sealing rubber ring, and the sealing box cover is closed. The power amplifier board is started, and the generated audio is amplified by the expander. At this time, the generated sound wave will pass through the coating sleeve part with the coating and be transmitted to the spring-sensitive corrugated part. The spring-sensitive corrugated part will vibrate according to the transmitted sound wave, so as to make high-frequency contact with the vibration sensor. The corresponding numbers are recorded by using the frequency of contact to evaluate the sound-absorbing effect of the measurement coating, making the sound absorption volume of the coating quantifiable, and reducing the cost of manufacturing the detection box.

[0021] When the present utility model is used, multiple measurement paints are pre-coated on multiple paint sleeve parts 34 respectively. The fixing bolt 36 is unscrewed from the bolt seat 35, so that the paint sleeve part 34 is removed from the fixed seat 31, and the pre-made paint sleeve part 34 with paint is replaced. The sound insulation component 3 is placed on the sealing rubber ring 4, the sealed box cover 2 is closed, the power amplifier board 32 is started, and the generated audio is amplified by the expander 33.
