tooth-shaped clamping parts used for being clamped with the inner edge of the standard C-shaped light steel keel are arranged on two side walls of the opening end of the U-shaped anti-skidding buckle; the safety card is connected with one side wall of the U-shaped anti-skidding buckle and is provided with a clamping part used for being clamped with the outer edge of the standard C-shaped light steel keel.

Furthermore, the nut is a hexagon nut, and a gasket is arranged between the nut and the closed end of the U-shaped anti-slip buckle.

Furthermore, spring gaskets are arranged at two ends of the metal spring.

Compared with the prior art, the beneficial effects of the utility model are that:

the invention realizes the effect of buffering and damping, and avoids the solid medium conduction of low-frequency vibration and medium-high frequency sound waves (acoustics refers to the solid sound transmission). The invention has no rigid connection with the original building structure and can cut off the transmission path of the foundation structure. The invention conforms to the noise vibration isolation technology, is convenient and fast to construct, has standard design, can effectively improve the construction efficiency by matching with the C-shaped standard metal keel, and enables large-area installation and construction of projects to be more convenient.

Detailed Description

The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.

As shown in fig. 1 to 8, the present embodiment provides a snap-in acoustic shock absorber, which is used for being fixed on a direct sound wave surface and forming a cavity fault with an original basic wall, and includes a U-shaped anti-slip snap 3, a polymer damping pad 4, a safety clip 5, a metal spring 7, and a screw rod; the closed end of the U-shaped anti-skid buckle 3 is provided with a screw hole, and a polymer damping pad 4 and a metal spring 7 are sequentially arranged in the U-shaped anti-skid buckle 3 from the closed end to the opening end; the screw rod 9 sequentially penetrates through the metal spring 7, the polymer damping pad 4 and the screw hole and is connected with the closed end of the U-shaped anti-skidding buckle 3 through the hexagonal nut 1;

tooth-shaped clamping parts used for being clamped with the inner edge of the standard C-shaped light steel keel 10 are arranged on two side walls of the opening end of the U-shaped anti-skidding buckle 3; the safety card 5 is connected with one side wall of the U-shaped anti-slip buckle 3 and is provided with a clamping part used for being clamped with the outer edge of the standard C-shaped light steel keel 10.

The buckle formula acoustics bumper shock absorber has realized the effect that cushions the shock attenuation to avoid the solid medium conduction of low frequency vibration and medium and high frequency sound wave (acoustics will be called solid transaudient). The fastening type acoustic shock absorber has no rigid connection with the original building structure, and can cut off the transmission path of the foundation structure. This buckle formula acoustics bumper shock absorber accords with noise vibrations shock insulation technique, and the construction is convenient, and the design is standard, and the cooperation uses C type standard metal fossil fragments can effectively promote the efficiency of construction, makes the engineering large tracts of land installation construction more convenient.

In this embodiment, the nut is a hexagon nut 1, and a gasket 2 is arranged between the hexagon nut and the closed end of the U-shaped anti-slip buckle 3, so that the stability is improved.

In this embodiment, spring washers (the first spring washer 6 and the second spring washer 8) are disposed at two ends of the metal spring 7, so as to increase the connection stability.

This buckle formula acoustics bumper shock absorber carries out scientific construction with current C type standard metal fossil fragments cooperation acoustics bumper shock absorber technique to through adjustment horizontal error, average mechanics vibration, the cooperation of multiple spot position is under construction. In practice, the performance of the wall furred ceiling sound insulation structural layer is strengthened, the installation of the wall furred ceiling sound insulation structural layer of being convenient for is used for fixing the sound wave and penetrates the face directly and improve the sound energy separation effect with the cavity fault that forms between the former basic wall body.

Through experimental test application, buckle acoustics bumper shock absorber cooperation C type standard metal keel orbital installation technology function is complete and the installation is convenient to effectively promote the weight of material self, reinforcing factor of safety accords with the damping that gives sound insulation and inhales sound construction technical requirement, is applicable to the theater, the concert hall, large-scale venue, the recording studio, the bar, the control room, airport motor car hall of waiting, house, elevator partition wall, public space such as fan pipeline damping technique provides quiet acoustics environment.
