Description

Framework wedge

Technical field

The utility model is related to a kind of framework wedge.

Background technology

With expanding economy, the progress of society, scientific research and commercial development are more and more to the demand of anechoic room, it is desirable to More and more higher.Anechoic room is widely used in the fields such as automobile, Aero-Space, household electrical appliance, and the Main Function of anechoic room is right Product carries out noise testing and acoustics performance measurement, and wedge absorber is the wedge peace under the critical component of anechoic room, prior art Inconvenience is unloaded in assembly and disassembly, and acoustically effective is bad,

Utility model content

For deficiency of the prior art, the utility model provides a kind of framework wedge.

A kind of framework wedge, including a framework, the lower portion are filled with acoustical cotton, and two sides have been covered each by table Face felt, bottom surface is coated with non-woven fabrics；The surface felt and non-woven fabrics are adjacent to acoustical cotton；All outermost surfaces of the framework Cover gauze.

Non-woven fabrics is environment-friendly materials of new generation, the features such as with moistureproof, ventilative, flexible, not combustion-supporting, light weight；Surface felt rises Sound-absorbing, it is fire-retardant to wait effect；Gauze good toughness, it is not combustion-supporting.

Preferably, the framework includes the square underframe surrounded by four zinc-plated square tube welding, the adjacent square tube of each two Junction be vertically provided with a vertical support frame being welded by perforated plate upwards；The end of the vertical support frame connects Connect a bearing diagonal frame one end；The other end of the bearing diagonal frame of one group of vertical support frame connection of homonymy is crossed to form the frame One triangle side of frame；A horizontal shore is connected between one group of intersection point of bearing diagonal frame per homonymy；By described perpendicular The connection of allotment support, bearing diagonal frame and horizontal shore, the framework formed two opposing parallel triangle sides and Two intersecting rectangle sides.

Preferably, four sides of the framework are equipped with four horizontal stiffeners from top to bottom, wherein, each side is most The reinforcement two ends of lower section connect the upper end of two of which adjacent upright support frame respectively.

Preferably, velcro is surrounded with around underframe, gauze is fixed on the outermost of framework by velcro.

Preferably, the bottom side of the underframe is provided with one group of L-type hook, and opposite side is provided with one group of U-shaped hook.

Beneficial effect：The utility model light weight, easy for installation, quick detachable, phase homogenous quantities can make bigger wedge, inhale Sound face increase, acoustically effective enhancing, and antipollution, it is more environmentally friendly, safer, more prevent fires.

Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe.

Shown in Fig. 1 to 4, a kind of framework wedge, including a framework, the lower portion is filled with acoustical cotton 1, two sides Surface felt 2 is covered each by, bottom surface is coated with non-woven fabrics 3；The surface felt 2 and non-woven fabrics 3 are adjacent to acoustical cotton 1；The frame All outermost surfaces of frame cover gauze 4.

Non-woven fabrics 3 is environment-friendly materials of new generation, the features such as with moistureproof, ventilative, flexible, not combustion-supporting, light weight；Surface felt 2 Sound-absorbing is played, it is fire-retardant to wait effect；The good toughness of gauze 4, it is not combustion-supporting.

The framework includes welding the square underframe for surrounding, the combination of the adjacent square tube 5 of each two by four zinc-plated square tubes 5 Place is vertically provided with a vertical support frame 6 being welded by perforated plate upwards；The end of the vertical support frame 6 is all connected with one The one end of bearing diagonal frame 7；The other end of the bearing diagonal frame 7 of one group of vertical support frame 6 connection of homonymy is crossed to form the frame One triangle side of frame；A horizontal shore 8 is connected between one group of intersection point of bearing diagonal frame 7 per homonymy；By described The connection of vertical support frame 6, bearing diagonal frame 7 and horizontal shore 8, the framework forms two opposing parallel triangle sides Face and two intersecting rectangle sides.

Four sides of the framework are equipped with four horizontal stiffeners 9 from top to bottom, wherein, each side bottom The two ends of reinforcement 9 connect the upper end of two of which adjacent upright support frame 6 respectively.

Velcro 10 is surrounded with around underframe, gauze 4 pastes the outermost for being fixed on framework by velcro 10.

The bottom side of the underframe is provided with one group of L-type hook 11, and opposite side is provided with one group of U-shaped hook 12.It is actually used When framework underframe of the present utility model pressed close into metope fix；Fix a peg on the wall first, one group of U-shaped hook 12 is hung Onto peg, the vertical plane of L-type hook 11 props up metope, realizes fixing.

Various modifications to these embodiments will be apparent for those skilled in the art, herein Defined General Principle can be real in other embodiments in the case where spirit or scope of the present utility model are not departed from It is existing.
