Technical Field

[0001] The utility model relates to the technical field of sound insulation testing, in particular to a device for testing the sound insulation performance of building materials. Background Art

[0002] With the development of society, the application of sound insulation building materials has become more and more extensive. Sound insulation materials refer to a type of material, component or structure that can block the propagation of sound or reduce the transmitted sound energy, thereby improving the sound absorption and sound insulation effect of buildings.

[0003] In the prior art, when testing the sound insulation performance of building materials, simply testing them indoors using a decibel meter is easily interfered with by external sounds, thereby affecting the accuracy of the sound insulation performance test of the building materials.

[0004] Therefore, a building material sound insulation performance testing device is proposed. Summary of the Invention

[0005] The purpose of the utility model is to provide a device for testing the sound insulation performance of building materials to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a device for testing the sound insulation performance of building materials, comprising two plates, a screw rod being installed on one side of one plate, and an end of the screw rod passing through one side of the other plate;

[0007] A soundproof cover is installed on one side opposite to the two plate bodies, and a loudspeaker and a decibel meter are installed inside the two soundproof covers respectively.

[0008] Preferably, a sound insulation pad is installed on the outer side of the sound insulation cover.

[0009] Preferably, the sound insulation pad is made of polyethylene.

[0010] Preferably, a first limiting rod and a second limiting rod are respectively installed on opposite sides of the two plates.

[0011] Preferably, the first limiting rods and the second limiting rods are arranged alternately.

[0012] Preferably, support columns are symmetrically installed on the other side of the two plates.

[0013] Preferably, the support column is made of rubber.

[0014] Preferably, a handle is installed at one end of the screw rod passing through the plate body.

[0015] Compared with the existing technology, the beneficial effect of the present invention is: the sound insulation cover and the wall are fitted together by the movement of the plate, and then the sound insulation effect of the wall is tested by the decibel meter and speaker inside the sound insulation cover. The sound insulation cover can prevent external sounds from affecting the test results, thereby improving the overall test effect and accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Example

[0023] See also Figure 1-4 The utility model provides a technical solution: a building material sound insulation performance testing device, comprising two plates 1, a screw rod 2 is installed on one side of one plate 1, and the end of the screw rod 2 passes through one side of the other plate 1;

[0024] A soundproof cover 7 is installed on one side of the two plates 1 that are opposite to each other. A loudspeaker 9 and a decibel meter 10 are installed inside the two soundproof covers 7 respectively.

[0025] like Figure 3 and Figure 4 As shown: a sound insulation pad 8 is installed on the outside of the sound insulation cover 7, and the material of the sound insulation pad 8 is polyethylene; through the above setting, the sound insulation pad 8 can fit the wall to the greatest extent after contacting the wall, so as to carry out subsequent testing work.

[0026] like Figure 1 and Figure 2As shown: the first limiting rod 4 and the second limiting rod 5 are respectively installed on the opposite side of the two plate bodies 1, and the first limiting rod 4 and the second limiting rod 5 are arranged alternately; through the above arrangement, the first limiting rod 4 and the second limiting rod 5 are staggered and inserted, which can limit the position between the two plate bodies 1 and facilitate the movement of the two plate bodies 1.

[0027] like Figure 3 and Figure 4 As shown: support columns 6 are symmetrically installed on the other side of the two plates 1, and the material of the support columns 6 is rubber; through the above arrangement, the support columns 6 can be continuously compressed after contacting the wall, thereby increasing the friction with the wall and avoiding the situation where the plates 1 move at will.

[0028] like Figure 1 and Figure 2 As shown: a screw rod 2 passes through one end of the plate body 1 and a turning handle 3 is installed; through the above arrangement, the screw rod 2 can be driven to rotate more conveniently and quickly.

[0029] Working principle: First, place the two plates 1 on the device on the inside and outside of the window or door frame respectively, then turn the handle 3 to rotate the screw rod 2, and the two plates 1 are moved by the rotation of the screw rod 2, and then the sound insulation cover 7 is driven to move, and the sound insulation pad 8 on the sound insulation cover 7 is in contact with the wall. When the sound insulation cover 7 and the sound insulation pad 8 are tightly fitted to the wall, the sound insulation performance of the wall can be tested through the speaker 9 and the decibel meter 10.
