Problems solved by technology

If it is necessary to measure the heat insulation effect of multiple pieces of glass for comparison, multiple glass heat insulation testers are needed for comparison. The disadvantages of this are: it leads to an increase in the detection cost, and the comparison effect is not intuitive enough
[0006] The existing technical solution mentioned above has the following defects: when displaying the glass display board, the temperature difference of the glass can only be observed through the senses, which is not accurate enough, and the display function of the glass display device is relatively single

Embodiment 1

[0036] Such as Figure 1-Figure 2 As shown, a glass heat and sound insulation performance test box includes a box body 1 , a glass frame 2 and a cover plate 3 .

[0037] Box 1, such as Figure 1-Figure 6 As shown, it is made of superstructure material. There is a through inner cavity between the two sides of the box body 1. The bottom of the inner cavity is provided with a heating plate 4. A noise source is suspended in the inner cavity. The noise source is suspended on the top of the inner cavity or The middle position; the outer side of the bottom of the box body 1 is provided with a cover plate 5, and the inside of the cover plate 5 is equipped with a relay, a temperature control circuit and an external noise source interface, wherein the cover plate 5 is only used for enclosure protection. Its size needs to be designed according to the actual electrical requirements.

[0038] In this embodiment, the noise source is a speaker, which can withstand a temperature below 80°C....

Embodiment 2

[0046] Such as Figure 1-Figure 4 As shown, compared with Embodiment 1, the glass frame 2 of this embodiment is provided with a mounting groove 8 on the side of the glass mounting groove 6 corresponding to the side of the box body 1 having an inner cavity, and the mounting groove 8 is used for mounting Hinge or hinge, the two glass frames 2 are respectively installed on the corresponding sides of the box body 1 through hinges or hinges, when replacing the glass to be tested, the glass frame 2 only needs to be rotated around the hinge 2 Unfold (refer to the structure of the door), which is convenient for frequent replacement of the glass to be tested.

[0047] Other components and principles of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0049] Such as Figure 1-Figure 5 As shown, compared with Embodiment 1, one side of the cover plate 3 of this embodiment is provided with a cover groove matching the glass frame 2, and the side of the glass frame 2 opposite to the glass installation groove 6 can be completely embedded in the cover. in the slot.

[0050] The notch edge of the cover groove is provided with an L-shaped block 11 in the middle, one side of the block 11 is fixed on the cover plate 3, and the other side of the block 11 is arranged towards the cover groove, and the block 11 is made of elastic material. The side of the glass frame 2 is provided with a locking groove 12 , and when the glass frame 2 is embedded in the cover groove, the locking block 11 can be just locked in the locking groove 12 .

[0051] During installation, remove the block 11, cover the cover plate 3 on the glass frame 2 to be covered, put down the block 11, and the block 11 will be stuck in the slot 12 of the box body 1, and the in...

Abstract

The invention provides a glass heat insulation and sound insulation performance test box and a test method thereof. The glass heat insulation and sound insulation performance test box comprises a box body, glass frames and a cover plate, wherein the box body is made of a metamaterial, a heating sheet is arranged at the bottom of an inner cavity between two side surfaces of the box body, a noise source is hung in the inner cavity, a cover plate is arranged on the outer side of the bottom of the box body, and a relay, a temperature control circuit and a noise source loudspeaker interface are arranged in the cover plate; a metamaterial is embedded in the glass frame, a metal frame wraps the glass frame, an opening corresponding to the inner cavity is formed in the middle of the glass frame, a glass mounting groove and an open groove which are sequentially formed in the opening in a surrounding mode from inside to outside are formed in one side of the glass frame, and the open groove is used for mounting a sealing strip; the two glass frames are detachably installed on the two side surfaces, which are provided with the inner cavity, of the box body respectively; and a metamaterial is embedded in the cover plate, a metal frame is wrapped outside the cover plate, the cover plate is arranged on the side surface, which is opposite to the box body, of the glass frame in a covering mode, the cover plate and the outer wall of the glass frame are detachably installed, and the heat insulation and sound insulation performance of the two pieces of glass can be detected through comparison.

Description

technical field [0001] The invention relates to the technical field of glass performance testing, in particular to a glass heat and sound insulation performance testing box and a testing method thereof. Background technique [0002] At present, the sound insulation performance test of glass is mainly carried out in the sound insulation laboratory. The sound insulation laboratory is composed of two reverberation chambers with a volume of not less than 50 cubic meters and an anechoic enclosure. The test equipment mainly includes noise generators, filters , power amplifier, microphone, loudspeaker, sound intensity probe, dual-channel analyzer, computer and sound pressure, sound intensity calibrator, etc.; when testing, randomly select three flat samples and cut them into specified sizes, or make the same material 1. For the flat test sample of the specified size made by the same process, the weight, area and thickness of the test piece are pre-tested before installation; then t...
