Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of felt, in particular to a reusable felt. Background Art
[0002] Felt, a commonly used tool in industry, is mostly made of wool, but also of cow hair or fiber, and is processed and bonded. Due to its good elasticity and very soft surface, it is widely used as a material for shockproofing, sealing, cushioning and elastic steel wire needle cloth base felt.
[0003] The existing felt is often squeezed during use, which can easily cause the entire felt to deform. Due to the influence of the felt material, the elastic recovery effect of the entire felt is not good, which can easily cause the felt to be damaged, making it inconvenient for users to reuse it. Summary of the invention
[0004] The utility model aims to provide a reusable felt to solve the problem in the above background technology that the currently used felt is inconvenient to be reused.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a reusable felt, comprising: a felt body and a fireproof layer, the bottom of the felt body is connected to an elastic layer, the bottom of the elastic layer is connected to a noise reduction layer, and the fireproof layer is connected to the bottom of the noise reduction layer.
[0006] Preferably, the elastic layer includes a first rubber layer and a second rubber layer.
[0007] Preferably, a first rubber strip, a second rubber strip and a third rubber strip are installed inside the first rubber layer and the second rubber layer.
[0008] Preferably, both ends of the first rubber strip and the second rubber strip are connected to each other.
[0009] Preferably, the noise reduction layer includes a first noise reduction plate, a second noise reduction plate and a third noise reduction plate.
[0010] Preferably, through holes are provided in the middle of the first noise reduction plate and the second noise reduction plate.
[0011] Compared with the prior art, the beneficial effect of the utility model is that when the reusable felt is used, the entire felt is squeezed and deformed, so that the first rubber strip, the second rubber strip and the third rubber strip are squeezed and collided with each other. Since the first rubber strip, the second rubber strip and the third rubber strip have a good elastic recovery effect, the first rubber layer and the second rubber have a better recovery effect, so that the entire felt is not easy to be damaged, and the user can reuse it, thereby increasing the service life of the entire felt. This is the use feature of the reusable felt.
[0012] 1. When the reusable felt is used, the first rubber layer and the second rubber layer are squeezed against each other, and the first rubber strip, the second rubber strip and the third rubber strip inside are deformed. The cooperation of the rubber strips can make the whole felt have a good recovery effect, and it can recover even if it is severely squeezed and deformed, so that the whole felt has the characteristic of being reusable.
[0013] 2. The reusable felt absorbs sound through the through holes on the first noise reduction board during use, and then blocks the sound through the second noise reduction board and the third noise reduction board. The cooperation of the first noise reduction board, the second noise reduction board and the third noise reduction board can better reduce and filter the noise, so that the noise reduction effect of the entire felt is better.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1 and Figure 5 The utility model provides a technical solution: a reusable felt, comprising: a felt body 1 and a fireproof layer 4, the bottom of the felt body 1 is connected to an elastic layer 2, the bottom of the elastic layer 2 is connected to a noise reduction layer 3, and the fireproof layer 4 is connected to the bottom of the noise reduction layer 3.
[0022] The elastic layer 2 includes a first rubber layer 201 and a second rubber layer 202. A first rubber strip 203, a second rubber strip 204 and a third rubber strip 205 are installed inside the first rubber layer 201 and the second rubber layer 202. Both ends of the first rubber strip 203 and the second rubber strip 204 are connected to each other, and the third rubber strip 205 is cross-interspersed between the first rubber strip 203 and the second rubber strip 204.
[0023] In a specific implementation, the reusable felt, since the third rubber strip 205 is inserted between the first rubber strip 203 and the second rubber strip 204, and the first rubber strip 203 and the second rubber strip 204 are connected to each other end to end, when the entire felt is squeezed during use, since the materials of the first rubber strip 203, the second rubber strip 204 and the third rubber strip 205 are all rubber materials, which have a good elastic recovery effect, the first rubber strip 203, the second rubber strip 204 and the third rubber strip 205 will be deformed when squeezed, and squeeze and collide with each other. When the felt is released, the first rubber strip 203, the second rubber strip 204 and the third rubber strip 205 will make the first rubber layer 201 and the second rubber layer 202 recover quickly, so that the recovery effect of the entire elastic layer 2 is better, so that the entire felt is not easy to be damaged, it is convenient for users to reuse it, and the service life of the entire felt is increased.
[0024] See also Figure 1 , Figure 3 and Figure 4 It can be seen that when in use, the entire felt can be quickly restored by the restoring effects of the first rubber strip 203 , the second rubber strip 204 and the third rubber strip 205 , so that it can be reused.
[0025] The noise reduction layer 3 includes a first noise reduction plate 301, a second noise reduction plate 302 and a third noise reduction plate 303. Through holes 304 are opened in the middle of the first noise reduction plate 301 and the second noise reduction plate 302. The first noise reduction plate 301, the second noise reduction plate 302 and the third noise reduction plate 303 are stacked and connected with each other.
[0026] In specific implementation, the reusable felt can reduce noise through the first noise reduction plate 301, the second noise reduction plate 302 and the third noise reduction plate 303 in the noise reduction layer 3 when in use. The noise reduction plates are all made of fiber cotton material. Relying on the mutual stacking of the first noise reduction plate 301, the second noise reduction plate 302 and the third noise reduction plate 303, the sound can be better filtered, and the higher the noise reduction plate 301, the greater the number of through holes 304 in the noise reduction plate, that is, the number of through holes 304 in the first noise reduction plate 301 is greater than that in the second noise reduction plate 302, and the number of through holes 304 in the second noise reduction plate 302 is greater than that in the third noise reduction plate 303. Therefore, the through holes 304 on the first noise reduction plate 301 can better absorb the sound, and the second noise reduction plate 302 and the third noise reduction plate 303 can better isolate the sound, thereby achieving a better noise reduction effect.
[0027] See also Figure 1 and Figure 2 It can be known that when in use, the first noise reduction plate 301, the second noise reduction plate 302 and the third noise reduction plate 303 can be stacked together to achieve a better noise reduction effect for the entire felt, thereby effectively achieving a noise reduction effect.
[0028] To sum up: the reusable felt, the whole felt is mainly composed of a felt body 1, an elastic layer 2, a noise reduction layer 3 and a fireproof layer 4. When in use, the felt body 1 is facing upward. Since the surface of the felt body 1 is usually made of wool, it is very comfortable to use and will not affect the normal use of the user. The fireproof layer 4 at the bottom is mainly a fireproof cowhide layer, which makes the whole felt have a good fireproof and flame retardant effect and meet the daily use needs of the user. This is the use feature of the reusable felt. The contents not described in detail in this description belong to the existing technology known to professional and technical personnel in this field.
