Description

Vibration damping pad

Technical Field

The utility model relates to a damping material, concretely relates to damping pad.

Background

The damping pad is mainly applied to houses, hotels, schools and business buildings; entertainment places such as KTV, night master singing and dancing halls and the like and other places needing sound insulation and vibration reduction have excellent damping and vibration reduction effects, and the floor material is a floating floor material with extremely high cost performance. Currently, the mainstream damping pad is a plate made of polyurethane, and the damping pad can realize a damping effect by being laid. For example, in the logistics industry, a transmission belt is required to be used for transmission, the transmission belt is generally directly installed on the ground, huge noise pollution is caused, meanwhile, vibration in the transportation process caused by vibration is large, the influence is large for some precise products or fragile products, the products are easily damaged, the traditional polyurethane has good noise reduction effect, but the vibration reduction strength is required to be enhanced, and particularly when the traditional polyurethane is applied to a vibration reduction pad of equipment, the problem of deformation is easily caused due to long-term extrusion, and the vibration reduction effect is further reduced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art, provide a damping pad, not only can satisfy higher damping intensity, can also play better noise reduction effect simultaneously.

The purpose of the utility model is realized through the following technical scheme:

a damping pad comprises an upper pad and a lower pad which are arranged up and down symmetrically, wherein a buffer layer is laid between the opposite surfaces of the upper pad and the lower pad;

the opposite surfaces of the upper cushion and the lower cushion are uniformly provided with a plurality of blind grooves, and the blind grooves form a cavity after the upper cushion and the lower cushion are spliced up and down;

the cavity is internally provided with a first pressing plate and a second pressing plate respectively, and a spring is arranged between the first pressing plate and the second pressing plate, so that the first pressing plate and the second pressing plate are respectively abutted against the top and the bottom of the cavity.

The design concept of the scheme is derived from a spring mattress, but is different from the spring mattress, the same thing of the spring mattress and the spring mattress is that a compression spring is introduced to be used as a support in the middle, the difference is that the scheme acts on occasions with larger pressure, namely the situation that the spring is completely compressed needs to be considered, therefore, a buffer layer is added between the upper cushion and the lower cushion, so that the buffer layer is compressed when the spring is compressed, the upper cushion and the lower cushion are relatively close to each other under the stress state, thereby being different from the traditional vibration damping pad which can generate irreversible deformation under the stress state, and simultaneously, the existence of the buffer layer can ensure that the side walls of the upper pad and the lower pad hardly deform in the spring compression process, or the upper cushion and the lower cushion are almost unchanged in thickness, namely the buffer layer is used as deformation quantity buffer of the spring, so that a good vibration damping effect is ensured.

Furthermore, the thickness of the buffer layer is larger than or equal to the maximum deformation of the spring, and the design can ensure that the deformation stored in the buffer layer completely meets the maximum compression of the spring.

Furthermore, the blind grooves are uniformly arranged on the opposite surfaces of the upper-layer cushion and the lower-layer cushion in a matrix distribution mode.

Furthermore, the upper layer cushion, the lower layer cushion and the buffer layer are bonded together through glue.

Furthermore, the upper cushion and the lower cushion are made of polyurethane materials.

Furthermore, the blind groove is circular, and the size of the blind groove is matched with that of the spring.

Furthermore, the cavity is filled with a buffer.

Furthermore, the buffer layer and the buffer are both made of silencing cotton.

The utility model has the advantages that: compare with traditional damping pad, this scheme increases the compression spring as elastic support and damping effect in damping pad to strengthen the support intensity of traditional damping pad, increased the supporting framework in traditional damping pad in other words, make under the user state, its maximum compression capacity is by the high decision of spring, the similar problem of local pressure deformation that appears of traditional damping pad can not appear, has improved damping intensity and noise reduction effect.

Detailed Description

The technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following description.

As shown in fig. 1, the damping pad comprises an upper pad 1 and a lower pad 2 which are arranged up and down symmetrically, and a buffer layer 7 is laid between the opposite surfaces of the upper pad 1 and the lower pad 2; the upper cushion 1, the lower cushion 2 and the buffer layer 7 are bonded together through glue. The opposite surfaces of the upper cushion 1 and the lower cushion 2 are uniformly provided with a plurality of blind grooves, the structure of the blind grooves can be shown in figure 3, the blind grooves form a cavity 1-2 after the upper cushion 1 and the lower cushion 2 are vertically spliced, the cavity 1-2 is filled with a buffer 6, and the structure of the blind grooves can be described with reference to figure 2. A first pressing plate 3 and a second pressing plate 4 are arranged in the cavity 1-2 respectively, and a spring 5 is arranged between the first pressing plate 3 and the second pressing plate 4, so that the first pressing plate 3 and the second pressing plate 4 are abutted to the top and the bottom of the cavity 1-2 respectively.

Optionally, a damping pad, the thickness of buffer layer 7 is greater than or equal to the maximum deformation of spring 5, wherein, upper cushion 1 and lower cushion 2 adopt the polyurethane material to make, buffer layer 7 and buffer 6 all adopt amortization cotton to make, the advantage of this design lies in when damping pad receives the extrusion, spring 5 takes place deformation compressed, under this state, the elastic coefficient of buffer layer 7 is less than upper cushion 1 and lower cushion 2 (amortization cotton elastic coefficient is less than polyurethane), therefore buffer layer 7 takes the lead to warp and is used for the deflection of buffer spring 5, and upper cushion 1 and lower cushion 2 then keep good elastic deformation under a certain degree, avoid taking place irreversible elastic deformation, in order to improve the damping effect of damping pad.

Optionally, in the vibration damping pad, blind grooves are uniformly formed in the opposite surfaces of the upper pad 1 and the lower pad 2 in a matrix distribution manner, the blind grooves are circular, and the size of the blind grooves is matched with that of the springs 5.

The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims.
