Description

Technical Field

[0001] This utility model relates to the technical field of glass testing equipment, and in particular to a glass material sound insulation testing device with a curved sealing structure. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material mainly composed of silicon dioxide and other oxides. Its raw materials usually include various inorganic minerals such as quartz sand, limestone, and soda ash. After being melted at high temperature, it is rapidly cooled and shaped to form a solid substance with an irregular atomic structure, which is widely used in the construction industry.

[0003] After the soundproof glass is manufactured and processed, it is necessary to conduct a sound insulation test to ensure that the glass has a good sound insulation effect. The existing sound insulation testing device can only test flat glass and is not convenient for testing curved glass. Therefore, a sound insulation testing device for glass materials with curved sealing structure is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a sound insulation testing device for glass materials with a curved sealing structure, so as to solve the problems and defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glass material sound insulation testing device with a curved sealing structure, comprising a bracket, a fixed platform fixedly installed at the bottom of the bracket, a fixed ring fixedly installed on the fixed platform, an electric telescopic rod fixedly installed at the top of the bracket, a hemispherical sound-absorbing cover fixedly installed at the free end of the electric telescopic rod, a speaker box fixedly installed on the top inner side of the hemispherical sound-absorbing cover, a first noise meter installed on the inner side of the hemispherical sound-absorbing cover, a second noise meter installed on the inner side of the fixed ring, and a soft sealant A fixedly installed at the bottom of the hemispherical sound-absorbing cover, enabling the hemispherical sound-absorbing cover to adapt to glass with different curvatures, and simultaneously satisfying the testing of flat glass and curved glass, thus improving the applicability of the device. An adsorption structure is provided on the fixed platform, the fixed ring, and the electric telescopic rod, and the adsorption structure is used to fix the glass.

[0006] Preferably, the adsorption structure includes a soft sealant B, a piston ring, a rectangular frame, and a sliding rod. The soft sealant B is fitted onto the top of the fixed ring, which has a movable cavity. The piston ring is slidably installed in the movable cavity. The rectangular frame is slidably installed on the top of the fixed platform and fixedly installed on the free end of the electric telescopic rod. The sliding rod is slidably installed on the bottom of the fixed ring, with its two ends fixedly installed on the top of the piston ring and the bottom of the rectangular frame, respectively. During the process of the electric telescopic rod driving the hemispherical sound-absorbing cover to descend, it can also drive the movable cavity to generate negative pressure, which can tightly adsorb the glass onto the top of the soft sealant B. During the contact between the soft sealant A and the glass, the glass is prevented from shifting, thus improving the test effect.

[0007] Preferably, the top of the flexible sealant B has four openings arranged in a ring array, and the openings communicate with the movable cavity.

[0008] Preferably, a fixing plate is fixedly installed on the inner side of the fixing ring, and the second noise meter is fixedly installed on the top of the fixing plate.

[0009] Preferably, a control panel is fixedly installed on one outer wall of the fixed platform.

[0010] Preferably, the flexible sealant A has a hollow cavity.

[0011] Preferably, the outer wall of the hemispherical sound-absorbing cover is covered with sound-absorbing cotton.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This glass material sound insulation testing device with a curved sealing structure uses a hemispherical sound-concentrating cover in conjunction with soft sealant A. This allows the hemispherical sound-concentrating cover to adapt to glass with different curvatures, simultaneously meeting the testing requirements for both flat and curved glass, thus improving the device's applicability. Through the adsorption structure, as the electric telescopic rod drives the hemispherical sound-concentrating cover to descend, it also generates negative pressure in the movable cavity, which can tightly adsorb the glass onto the top of the soft sealant B. During the contact between the soft sealant A and the glass, it prevents the glass from shifting, thereby improving the testing results. Attached Figure Description

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a glass material sound insulation testing device with a curved sealing structure, including a bracket 1, a fixed platform 2 fixedly installed at the bottom of the bracket 1, a fixed ring 3 fixedly installed on the fixed platform 2, an electric telescopic rod 4 fixedly installed at the top of the bracket 1, a hemispherical sound-concentrating cover 5 fixedly installed at the free end of the electric telescopic rod 4, and a speaker box 9 fixedly installed on the top inner side of the hemispherical sound-concentrating cover 5. A first noise meter 10 is provided inside the hemispherical sound-concentrating cover 5, and a second noise meter 12 is provided inside the fixed ring 3. The speaker 9 generates noise, which is used by the first noise meter 10 and the second noise meter 12 to detect the noise at the top and bottom of the glass 17, thereby testing the sound insulation effect of the glass 17. The soft sealant A6 fixedly installed at the bottom of the hemispherical sound-absorbing cover 5 allows the hemispherical sound-absorbing cover 5 to adapt to glass 17 with different curvatures, and can simultaneously meet the testing requirements of flat glass and curved glass, thus improving the applicability of the device. The adsorption structure set on the fixed platform 2, the fixed ring 3, and the electric telescopic rod 4 is used to fix the glass.

[0022] Furthermore, the adsorption structure includes a soft sealant B7, a piston ring 13, a rectangular frame 14, and a sliding rod 15. The soft sealant B7 is fitted onto the top of the fixed ring 3, which has a movable cavity. The piston ring 13 is slidably installed in the movable cavity. The rectangular frame 14 is slidably installed on the top of the fixed platform 2 and is fixedly installed on the free end of the electric telescopic rod 4. The sliding rod 15 is slidably installed on the bottom of the fixed ring 3, and its two ends are fixedly installed on the top of the piston ring 13 and the bottom of the rectangular frame 14, respectively. When the electric telescopic rod 4 is activated, its free end pushes the hemispherical sound-absorbing cover 5, the soft sealant A6, the rectangular frame 14, the sliding rod 15, and the piston ring 13 downwards. As the piston ring 13 moves downwards, a negative pressure is generated in the movable cavity, which can tightly adsorb the glass 17 onto the top of the soft sealant B7. During the contact between the soft sealant A6 and the glass 17, the glass 17 is prevented from shifting, thus improving the test results.

[0023] Furthermore, the top of the soft sealant B7 has four openings 8 arranged in a ring array, and the openings 8 communicate with the movable cavity.

[0024] Furthermore, a fixing plate 11 is fixedly installed on the inner side of the fixing ring 3, and the second noise meter 12 is fixedly installed on the top of the fixing plate 11.

[0025] Furthermore, a control panel 16 is fixedly installed on one outer wall of the fixed platform 2.

[0026] Furthermore, the flexible sealant A6 has a hollow cavity.

[0027] Furthermore, the outer wall of the hemispherical sound-absorbing cover 5 is covered with sound-absorbing cotton.

[0028] Working principle: Place glass 17 on top of flexible sealant B7. Activate the electric telescopic rod 4 via control panel 16. The free end of the electric telescopic rod 4 pushes the hemispherical sound-absorbing cover 5, flexible sealant A6, rectangular frame 14, sliding rod 15, and piston ring 13 downwards. As the piston ring 13 moves downwards, it creates negative pressure in the movable cavity, tightly adhering glass 17 to the top of flexible sealant B7. As the hemispherical sound-absorbing cover 5 and flexible sealant A6 descend, flexible sealant A6 comes into contact with the top of glass 17, covering the top of glass 17. Activate speaker 9 via control panel 16. Speaker 9 generates noise, which is detected by the first noise meter 10 and the second noise meter 12 at the top and bottom of glass 17, thus testing the sound insulation effect of glass 17.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
