Description

Technical Field

[0001] The utility model belongs to the technical field of flexible hose connection devices, and in particular relates to a connection structure of an ultra-flexible high-pressure hose. Background Art

[0002] Flexible hose is a piping system with bending performance and flexibility, which is widely used in various industries, such as liquid transportation, gas transmission, hydraulic system, etc. Flexible hose is usually made of flexible materials such as rubber, plastic or textile materials, and can adapt to complex working environment and pipeline layout.

[0003] However, there are some problems with the connection structure of the current flexible hose. In order to ensure the stability and sealing of the connection with the hose, the connection structure design in the prior art is often very complicated. They may involve a combination of multiple connection parts, sealing elements or support structures to ensure a firm connection and good sealing performance. Such a complex connection structure often requires a larger axial dimension to ensure the reliability and strength of the connection. However, the complexity and large axial dimension of this connection structure lead to some problems.

[0004] First, such a connection structure is often not flexible enough when the flexible hose needs to bend or turn. Due to the rigidity or large size of the connection structure, the hose may be restricted or overstressed when bending or turning, resulting in kinking or fatigue rupture of the hose. This seriously affects the normal delivery function of the hose.

[0005] Secondly, the complex connection structure not only increases the difficulty of manufacturing and installation, but also increases the cost of the system and the complexity of maintenance. In order to ensure the stability and sealing of the connection, additional parts, tools and operating steps may be required, which increases the cost of manufacturing and maintenance. In addition, the complex connection structure also requires more time and effort for installation and maintenance, reducing work efficiency.

[0006] Therefore, based on some of the above prior art situations, the present application has been further designed and improved. Utility Model Content

[0026] Reference Figures 1 to 5, a connection structure of an ultra-flexible high-pressure hose, comprising a connection seat 1, with connectors 2 for connecting a hose 3 assembled on both sides of the connection seat 1; the connection seat 1 comprises an annular end face abutment plate 4, with an abutting ring tube 5 arranged on the inner ring side of the end face abutment plate 4; the outer side surface of the abutting ring tube 5 and the inner side surface of the connector 2 cooperate to compress and fix the tube wall layer of the hose 3. The outer side surface of the abutting ring tube 5 and the inner side surface of the connector 2 are provided with a fastening toothed ring 6 for biting and embedding into the tube wall layer. In order to avoid damage to the abutting ring tube 5 when the hose 3 is bent, the end surfaces on both sides of the abutting ring tube 5 do not exceed the end surface of the connector 2. The utility model makes an innovative design for the connection structure of the hose 3, greatly simplifies the connection structure of the hose 3 and the connector 2, and reduces the length of the connection structure, so that the ratio of the radial dimension a to the axial dimension b of the connection structure can be greater than 2, making the connection structure more suitable for the connection occasions of the flexible hose 3.

[0027] In particular, the middle of the abutting ring tube 5 is a flow hole 7 for fluid to pass through. The flow hole 7 is set as a diversion structure with expanded openings on both sides. The diversion structure can divert the fluid flowing through the joint 2 in the hose 3, reduce the scouring force of the fluid on the joint between the abutting ring tube 5 and the pipe wall layer, and destroy the sealing.

[0028] As a preferred embodiment of the utility model, the fastening tooth ring 6 on the abutting ring tube 5 and the fastening tooth ring 6 on the joint 2 are alternately distributed, so that the deformation of the pipe wall layer is uniform at all locations, avoiding the pipe wall layer being damaged by the fastening tooth rings 6 on both sides being engaged and embedded at the same location, and at the same time ensuring that the connection structure fixes the pipe wall layer more tightly. The cross section of the fastening tooth ring 6 is a right triangle, and the hypotenuse of the right triangle is located on the side of the insertion direction of the pipe wall layer. This design allows the pipe wall layer to be smoothly inserted into the joint 2. After insertion, the fastening tooth ring 6 is engaged and embedded in the surface of the pipe wall layer, making it difficult for the pipe wall layer to be pulled out.

[0029] In addition, in order to strengthen the assembly of the connector 2 and the hose 3, a first assembly hole 8 is provided on the end face plate 4, and a second assembly hole 9 is provided on the connector 2. The first assembly hole 8 and the second assembly hole 9 are assembled and fixed by bolt connection, so that the connection seat 1 can be tightly assembled and fixed with the connector 2. A sealing gasket 10 is installed between the end face plate 4 and the connector 2 to ensure the sealing of the connection structure and the hose 3.

[0030] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
