Description

Technical Field

[0001] This utility model relates to the field of silicone tubes, specifically to a highly elastic shock-absorbing silicone tube. Background Technology

[0002] Traditional shock-absorbing silicone tubes have many problems under dynamic load conditions, such as rapid elastic decay and uneven energy dissipation. Conventional single-layer or double-layer structures are prone to permanent deformation under repeated compression, and the tube body often cracks due to local stress concentration in high-frequency vibration scenarios.

[0003] In existing technologies, increasing the wall thickness or adding a rigid support layer can improve strength, but it will increase the weight of the tube and shorten the effective elastic stroke; using a single foamed silicone can improve cushioning, but the poor stability of the closed-cell structure leads to a decrease in tear resistance. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned deficiencies and provide a highly elastic shock-absorbing silicone tube. Under dynamic load conditions and high-frequency vibration scenarios, this tube solves the technical problems of existing technologies, such as rapid elastic decay, uneven energy dissipation, easy permanent deformation, cracking due to local stress concentration, and difficulty in balancing strength and elasticity, through the combined design of a gradient silicone base layer, a hollow elastic skeleton layer, a self-healing silicone layer, a rubber shock-absorbing ring, and spiral metal wire.

[0005] The objective of this utility model is achieved through the following means:

[0006] A highly elastic shock-absorbing silicone tube includes a gradient silicone base layer, a hollow elastic skeleton layer, and a self-healing silicone layer. The hollow elastic skeleton layer is disposed outside the gradient silicone base layer, and the self-healing silicone layer is disposed outside the hollow elastic skeleton layer. Rubber shock-absorbing rings are evenly distributed on the inner wall of the gradient silicone base layer, and spiral metal wires are embedded in the corners of the hollow elastic skeleton layer.

[0007] Furthermore, thermosensitive color-changing microcapsules are equidistantly embedded inside the hollow elastic skeleton layer. The thermosensitive color-changing microcapsules are connected to the hollow elastic skeleton layer and the self-healing silicone layer respectively. One end of the thermosensitive color-changing microcapsule penetrates and extends into the interior of the hollow elastic skeleton layer.

[0008] When the ambient temperature of the silicone tube changes, the substances inside the thermochromic microcapsules will undergo physical or chemical reactions due to the temperature change, causing the microcapsules to display different colors. By observing the color change in this area of ​​the silicone tube, staff can quickly know the temperature environment in which the silicone tube is located.

[0009] Furthermore, the other end of the thermochromic microcapsule extends through and to the outside of the self-healing silicone layer, and the thermochromic microcapsule is fixedly connected to the hollow elastic skeleton layer and the self-healing silicone layer.

[0010] Furthermore, a protective net is provided on the outside of the self-healing silicone layer, and the protective net is fixedly connected to the self-healing silicone layer;

[0011] The protective net is woven from high-strength, corrosion-resistant fiber materials with a suitable mesh size that fits tightly to the outer surface of the silicone tube. This not only protects the outer layer from scratches by sharp objects but also disperses external pressure, enhancing its impact resistance.

[0012] Furthermore, a reinforcing rib layer is provided between the protective net and the self-healing silicone layer, and the reinforcing rib layer is distributed in a grid pattern;

[0013] The reinforcing rib layer is made of high-strength plastic material, which is tightly connected to the protective net and the outer self-healing silicone layer. The reinforcing rib further enhances the connection strength between the protective net and the outer layer, and at the same time can help the protective net disperse external pressure and improve the overall structural strength of the silicone tube.

[0014] Furthermore, the self-healing silicone layer has a flow channel on its exterior, and the flow channel is spirally distributed along the axial direction of the self-healing silicone layer.

[0015] The flow channel can form a flow channel on the surface of the silicone tube. When water stains or other liquids adhere to the surface of the silicone tube, they can guide the liquid to drain quickly, prevent the liquid from accumulating on the surface of the silicone tube and causing corrosion to the outer layer of the silicone tube, and extend the service life of the silicone tube.

[0016] The beneficial effects of this utility model are:

[0017] This utility model achieves a reasonable distribution of elasticity and strength in different parts through a gradient silicone base layer, optimizing performance according to stress requirements; the hollow elastic skeleton layer works in conjunction with the spiral metal wire to enhance the structural strength of the tube while ensuring that the elastic stroke is not compressed; the self-healing silicone layer can repair minor damage to the tube in a timely manner, effectively extending its service life; the rubber shock-absorbing ring on the inner wall further enhances the shock absorption effect.

[0018] The synergistic effect of multiple structures gives the silicone tube the advantages of being lightweight, elastic, having high tear resistance, and uniform energy dissipation. It solves the technical problems in the prior art, such as rapid elastic decay, easy permanent deformation, stress concentration leading to cracking, and difficulty in balancing strength and elasticity.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. This embodiment refers to... Figures 1-3 The present invention relates to a highly elastic shock-absorbing silicone tube, comprising a gradient silicone base layer 1, a hollow elastic skeleton layer 2, and a self-healing silicone layer 3. The hollow elastic skeleton layer 2 is disposed outside the gradient silicone base layer 1, and the self-healing silicone layer 3 is disposed outside the hollow elastic skeleton layer 2. Rubber shock-absorbing rings 4 are evenly distributed on the inner wall of the gradient silicone base layer 1. Spiral metal wires 5 are embedded in the corners of the hollow elastic skeleton layer 2. The gradient silicone base layer 1 is a gradient silicone matrix containing boron nitride nanosheets, with a Shore hardness gradient from 30A on the inner side of the tube to 50A on the outer side. The hollow elastic skeleton layer 2 is a topologically... The optimized dodecahedral hollow elastic skeleton forms a negative Poisson's ratio structure with a porosity within a certain range. The self-healing silicone layer 3 is coated with dynamic disulfide bonds. The spiral metal wire 5 is made of alloy material with good toughness and strength. Its spiral shape does not affect the overall elasticity of the silicone tube, enhances the axial and radial load-bearing capacity of the silicone tube, and also plays a supporting and reinforcing role for the hollow elastic skeleton layer 2. The rubber damping ring 4 is made of elastic rubber material with an arc-shaped cross section and is integrally formed with the inner wall of the inner layer. The rubber damping ring 4 can perform secondary buffering of the impact force of the fluid when the fluid passes through the silicone tube, further reducing vibration transmission.

[0024] like Figure 1 and Figure 2 As shown, thermosensitive color-changing microcapsules 6 are equidistantly embedded inside the hollow elastic skeleton layer 2, and one end of the thermosensitive color-changing microcapsule 6 penetrates and extends into the interior of the hollow elastic skeleton layer 2.

[0025] When the ambient temperature of the silicone tube changes, the substances inside the thermosensitive color-changing microcapsules 6 will undergo physical or chemical reactions due to the temperature change, causing the microcapsules to display different colors. By observing the color change in this area of ​​the silicone tube, staff can quickly know the temperature environment in which the silicone tube is located.

[0026] like Figure 1 and Figure 2 As shown, the other end of the thermochromic microcapsule 6 extends through and to the outside of the self-healing silicone layer 3, and the thermochromic microcapsule 6 is fixedly connected to the hollow elastic skeleton layer 2 and the self-healing silicone layer 3.

[0027] like Figure 1 and Figure 2 As shown, a protective net 8 is provided on the outside of the self-healing silicone layer 3, and the protective net 8 is fixedly connected to the self-healing silicone layer 3.

[0028] The protective net 8 is woven from high-strength, corrosion-resistant fiber material with a suitable mesh size that fits tightly to the outer surface of the silicone tube. It can protect the outer layer from scratches by sharp objects and also disperse external pressure, thus improving its impact resistance.

[0029] like Figure 1 and Figure 2 As shown, a reinforcing rib layer 7 is provided between the protective net 8 and the self-healing silicone layer 3, and the reinforcing rib layer 7 is distributed in a grid pattern;

[0030] The reinforcing rib layer 7 is made of high-strength plastic material, which is tightly connected to the protective net 8 and the outer self-healing silicone layer 3. The reinforcing rib further enhances the connection strength between the protective net 8 and the outer layer, and at the same time can help the protective net 8 disperse external pressure and improve the overall structural strength of the silicone tube.

[0031] like Figure 1 and Figure 2 As shown, a guide groove 9 is provided on the outside of the self-healing silicone layer 3, and the guide groove 9 is spirally distributed along the axial direction of the self-healing silicone layer 3.

[0032] The flow channel 9 can form a flow channel on the surface of the silicone tube. When water stains or other liquids adhere to the surface of the silicone tube, they can guide the liquid to drain quickly, prevent the liquid from accumulating on the surface of the silicone tube and causing corrosion to the outer layer of the silicone tube, and extend the service life of the silicone tube.

[0033] The working principle of a high-elasticity shock-absorbing silicone tube in this embodiment is as follows: The gradient silicone base layer 1 contains boron nitride nanosheets with varying hardness, which can initially disperse the stress generated by external vibration or pressure. The inner wall rubber shock-absorbing ring 4 provides secondary buffering against fluid impact or internal vibration through elastic deformation, improving the shock absorption effect. The dodecahedral hollow structure and negative Poisson's ratio of the hollow elastic skeleton layer 2 enable it to efficiently absorb and disperse energy. The spiral metal wire 5 at the corners enhances the stability and load-bearing capacity of the skeleton. Thermosensitive color-changing microcapsules 6 are embedded in the hollow elastic skeleton layer 2 and extend to the outside of the self-healing silicone layer 3. Their color changes with temperature, making it easy to observe the temperature. The dynamic disulfide bond network of the self-healing silicone layer 3 can repair surface cracks at appropriate temperatures. Its outer guide channel 9 guides liquid out and prevents corrosion. The protective net 8 resists external physical damage. The reinforcing rib layer 7 strengthens the connection between the protective net 8 and the self-healing silicone layer 3 and disperses pressure. The synergistic effect of each structure enables the silicone tube to have good shock absorption, self-healing, temperature display and protection performance under complex working conditions, which is a significant improvement over the existing technology.

[0034] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
