Description

Technical Field

[0001] This utility model relates to the field of silicone hose equipment technology, specifically a bending support structure and a silicone hose. Background Technology

[0002] The intake silicone hose has bends and transitions. Due to the high temperature and large flow rate of the gas between the turbocharger and the engine, the hose must be made of fabric-reinforced silicone. When the pressure in the line is too high, the hose is prone to rupture and leakage. In the existing technology, when the hose is bent, if there is no damping support component to provide additional support and cushioning, the material at the bend will be subjected to greater stress and friction. This additional stress and friction will cause wear on the hose material, which may accelerate the aging and damage of the hose over a long period of use. It cannot provide elastic support and protection at the bend, nor can it provide damping support. Using a single rigid material to support the bend of the hose is not effective.

[0003] For example, the authorized patent document with application number CN202320908557.X discloses a silicone hose, which includes a hose body. The hose body includes a straight section and a bending transition section. The hose body includes a silicone outer layer, a mesh fabric layer and a plain woven fabric layer. The two plain woven fabric layers are disposed between the two mesh fabric layers. The silicone outer layer is located outside the mesh fabric layer. At the bending transition section of the hose body, two aramid fabric reinforcing layers are added between the two plain woven fabric layers. The hose body is also equipped with a support structure on its exterior.

[0004] The aforementioned patent exists. When a hose is bent, if there is no damping support component to provide additional support and cushioning, the material at the bend will be subjected to greater stress and friction. This additional stress and friction will cause wear on the hose material, and may accelerate the aging and damage of the hose under long-term use. It cannot provide elastic support and protection at the bend, nor can it provide damping support. Using a single rigid material to support the bend of the hose is not effective. Therefore, we need to provide a bending support structure and a silicone hose. Utility Model Content

[0005] The purpose of this invention is to provide a bending support structure and a silicone hose. A damping mechanism is set at the bending point of the hose body, and the elastic support can deform under external force to adapt to different support requirements. This flexibility allows the elastic support to adapt well to changes in the shape and size of the hose bending point, avoiding rigid support which is prone to damage. It protects the hose and its connecting parts from damage caused by vibration, extends service life, and solves the problem mentioned in the background art that when the hose is bent, if there is no damping support component to provide additional support and buffer, the material at the bending point will be subjected to greater stress and friction. This additional stress and friction will lead to wear of the hose material, and may accelerate the aging and damage of the hose under long-term use.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 The present invention provides a technical solution: a bending support structure, including two fixed rings 1, and also includes a damping mechanism 2, an upper buffer damping assembly 21, a lower buffer damping assembly 22 and a fixing member 3;

[0030] The surfaces of the two fixed rings 1 are provided with damping mechanisms 2 for energy absorption. The damping mechanism 2 includes an upper buffer damping assembly 21 and a lower buffer damping assembly 22 disposed on the top of the two fixed rings 1.

[0031] Both the upper buffer damping assembly 21 and the lower buffer damping assembly 22 are mounted on the two fixed ring bodies 1 by fasteners 3;

[0032] Specifically, a damping mechanism 2 is installed at the bend of the hose body 6. The elastic support can deform under external force to adapt to different support requirements. This flexibility allows the elastic support to adapt well to the shape and size changes at the bend of the hose, avoiding rigid support, which is prone to damage, protecting the hose and its connecting parts from damage caused by vibration, and extending its service life.

[0033] The upper buffer damping assembly 21 includes an upper short plate 211 and an upper long plate 212 disposed on the top of the two fixed ring bodies 1. The upper short plate 211 and the upper long plate 212 are hinged at one end, and the upper damper body 213 is hinged to one side of the upper short plate 211 and the upper long plate 212.

[0034] In this embodiment, as Figure 1 As shown, when the silicone hose deforms at the bend, the positions of the two fixed rings 1 change, causing the upper short plate 211 and the upper long plate 212 to rotate. Since an upper damper body 213 is hinged between the upper short plate 211 and the lower short plate 221, excessive rotation between the upper short plate 211 and the upper long plate 212 is avoided, further limiting the deformation of the hose body 6. Simultaneously, a lower damper body 223 is hinged between the lower short plate 221 and the lower long plate 222. By setting two damper bodies respectively located at the soft... The top and bottom of the hose body 6 provide bidirectional damping force to reduce the bending and floating of the hose body 6 and enhance the support effect. Compared with rigid support, its flexible support effect is better. Two inclined support seats 2202 are installed on the lower buffer damping assembly 22, and the inclined support seats 2202 are further supported by two spring dampers 2201 to absorb the impact force. At the same time, the top of the two inclined support seats 2202 is provided with an arc-shaped groove 5, which is adapted to the hose body 6 and fits the hose body 6 better.

[0035] The upper connecting ring 31 is snapped onto the fixed ring 1, and the lower connecting ring 32 is snapped onto the fixed ring 1. The mounting bolt 41 passes through the upper connecting ring 31 and the lower connecting ring 32 and is threaded onto the mounting nut 42, thus fixing the upper connecting ring 31 and the lower connecting ring 32 onto the fixed ring 1, thereby completing the installation of the damping mechanism 2 on the hose body 6.

[0036] Inside the hose body 6, a platinum-cured silicone rubber layer is provided as the inner rubber layer 62, which serves as the inner wall of the hose and comes into direct contact with the transmission medium. It has good oil resistance, corrosion resistance, heat resistance, and smoothness to ensure smooth transmission of the medium and avoid contamination of the medium. The reinforcing layer 61 consists of a fiber layer 611 and a steel wire layer 612, which enhances the hose's pressure resistance and support. The braided fiber can form a mesh structure, which keeps the hose structurally stable under pressure; the steel wire has higher strength and rigidity, and can provide stronger support.

[0037] The lower buffer damping assembly 22 includes a lower short plate 221 and a lower long plate 222 disposed at the bottom of the two fixed ring bodies 1. The lower short plate 221 and the lower long plate 222 are hinged at adjacent ends. The lower damper body 223 is hinged to one side of the lower short plate 221 and the lower long plate 222. An elastic support member 220 is disposed on the top of the lower buffer damping assembly 22.

[0038] Specifically, such as Figure 3As shown, a lower damper body 223 is hinged between the lower short plate 221 and the lower long plate 222. By setting two damper bodies at the top and bottom of the hose body 6 respectively, bidirectional damping force is provided to reduce the bending and floating of the hose body 6 and enhance the support effect. Compared with rigid support, its flexible support effect is better.

[0039] The elastic support 220 includes two spring dampers 2201 fixedly installed on the top of the lower short plate 221 and the lower long plate 222, and the top of the two spring dampers 2201 is fixedly installed with inclined support seats 2202.

[0040] Furthermore, such as Figure 4 As shown, two inclined support seats 2202 are installed on the lower buffer damping assembly 22, and the inclined support seats 2202 are further supported by two spring dampers 2201 to absorb the impact force.

[0041] The fastener 3 includes two upper connecting rings 31 disposed at the bottom of the upper buffer damping assembly 21. The tops of the two upper connecting rings 31 are respectively fixedly installed at the bottoms of the upper short plate 211 and the upper long plate 212. The top of the lower buffer damping assembly 22 is provided with two lower connecting rings 32. The two lower connecting rings 32 are respectively installed at the tops of the lower short plate 221 and the lower long plate 222. Both the upper connecting rings 31 and the lower connecting rings 32 are installed on the surface of the fixed ring 1.

[0042] Among them, such as Figure 5 As shown, the upper connecting ring 31 is snapped onto the fixed ring 1, and the lower connecting ring 32 is snapped onto the fixed ring 1. The mounting bolt 41 passes through the upper connecting ring 31 and the lower connecting ring 32 and is threaded onto the mounting nut 42, thus fixing the upper connecting ring 31 and the lower connecting ring 32 onto the fixed ring 1, thereby completing the installation of the damping mechanism 2 on the hose body 6.

[0043] It also includes bolts 4 for fixing the upper connecting ring 31 and the lower connecting ring 32 to the surface of the fixed ring 1. The bolts 4 include two mounting bolts 41 that are slidably mounted on the surfaces of the upper connecting ring 31 and the lower connecting ring 32. The surfaces of the two mounting bolts 41 are threaded with mounting nuts 42, and the top of the mounting nuts 42 is in contact with the bottom of the lower connecting ring 32.

[0044] It should be noted that, as Figure 5 As shown, the mounting bolt 41 passes through the upper connecting ring 31 and the lower connecting ring 32, and is threaded onto the mounting nut 42, so that the upper connecting ring 31 and the lower connecting ring 32 are fixed on the fixed ring 1, thereby completing the installation of the damping mechanism 2 on the hose body 6.

[0045] Both inclined support bases 2202 have arc-shaped grooves 5 on their tops;

[0046] Among them, such as Figure 4 As shown, the top of both inclined support bases 2202 is provided with arc-shaped grooves 5, which are adapted to the hose body 6 and fit the hose body 6 more closely.

[0047] A silicone hose includes a bending support structure. A hose body 6 is fixedly installed inside two fixing rings 1. A reinforcing layer 61 for strengthening the support of the hose body 6 is provided inside the hose body 6. The hose body 6 includes an inner rubber layer 62. An outer rubber layer 63 is provided on the surface of the inner rubber layer 62, and the reinforcing layer 61 is located between the inner rubber layer 62 and the outer rubber layer 63.

[0048] The reinforcing layer 61 includes a braided fiber layer 611 and a steel wire layer 612;

[0049] In this embodiment, a platinum-cured silicone rubber layer 62 is provided inside the hose body 6 as the inner rubber layer 62, which serves as the inner wall of the hose and is in direct contact with the transmission medium. It has good oil resistance, corrosion resistance, heat resistance and smoothness to ensure smooth transmission of the medium and avoid contamination of the medium. The reinforcing layer 61 consists of a fiber layer 611 and a steel wire layer 612, which enhances the hose's pressure resistance and support. The braided fiber can form a mesh structure, which keeps the hose structurally stable under pressure; the steel wire has higher strength and rigidity, which can provide stronger support.

[0050] The inner rubber layer 62 is a platinum vulcanized silicone layer, the outer rubber layer 63 is a high-temperature resistant adhesive rubber layer, and the surface of the outer rubber layer 63 is fitted with a wear-resistant outer wall layer 7.

[0051] Among them, the wear-resistant outer wall layer 7 has better durability, thereby extending the service life. Inside the hose body 6, a platinum vulcanized silicone layer is set as the inner rubber layer 62, which serves as the inner wall of the hose and is in direct contact with the transmission medium. It has good oil resistance, corrosion resistance, heat resistance and smoothness.

[0052] When the silicone hose deforms at the bend, the positions of the two fixed rings 1 change, causing rotation between the upper short plate 211 and the upper long plate 212. Since an upper damper body 213 is hinged between the upper short plate 211 and the lower short plate 221, excessive rotation between them is prevented, further limiting the deformation of the hose body 6. Simultaneously, a lower damper body 223 is hinged between the lower short plate 221 and the lower long plate 222. By setting two damper bodies at the top and bottom of the hose body 6 respectively, bidirectional damping force is provided, reducing the bending and floating of the hose body 6 and enhancing the support effect. Compared to rigid support, its flexible support effect is better. Furthermore, two inclined support seats 2202 are installed on the lower buffer damping assembly 22, and two... Spring damper 2201 provides auxiliary support to inclined support seat 2202, further absorbing impact force. At the same time, both inclined support seats 2202 have arc-shaped grooves 5 on their tops. The arc-shaped grooves 5 are adapted to the hose body 6, making it fit the hose body 6 more closely. Inside the hose body 6, a platinum vulcanized silicone layer is set as the inner rubber layer 62, which serves as the inner wall of the hose and is in direct contact with the transmission medium. It has good oil resistance, corrosion resistance, heat resistance, and smoothness to ensure smooth transmission of the medium and avoid contamination of the medium. The reinforcing layer 61 consists of a fiber layer 611 and a steel wire layer 612, which enhances the hose's pressure resistance and support. The braided fiber can form a mesh structure, which keeps the hose structurally stable under pressure; the steel wire has higher strength and rigidity, which can provide stronger support.
