Description

Technical Field

[0001] This utility model relates to the field of hose connection technology, and in particular to an anti-vibration flexible hose connection assembly. Background Technology

[0002] In industrial piping systems, HVAC, water supply and drainage, fire protection, and mechanical equipment, hoses are widely used as key connecting elements in various fluid transmission systems, undertaking multiple functions such as media transportation, equipment displacement compensation, vibration absorption, and noise isolation. Due to their good flexibility, adaptability, and ease of installation, hoses have shown significant advantages in dealing with complex spatial layouts and dynamic working conditions. However, in practical applications, the connection between hoses and pipes or other equipment is a crucial link in the entire system, and the reliability of its connection structure directly affects the operational stability and safety of the entire system.

[0003] Currently, traditional hose connections mainly use clamps, flanges, threads, or quick couplings for fixing. These connection structures have certain connection strength and sealing performance in static or low-vibration environments. However, under dynamic load conditions, due to the lack of effective buffering, vibration isolation, and flexible connection design, the connection structure is prone to failure due to stress concentration, vibration fatigue, or axial displacement, leading to separation between the hose and the connector or sealing failure.

[0004] Therefore, there is an urgent need to provide a shock-resistant flexible hose connection assembly. Utility Model Content

[0005] In order to overcome the shortcomings of existing hose connection methods, such as easy loosening due to stress concentration under dynamic load conditions and lack of effective buffering and vibration isolation design, this utility model provides a shock-resistant hose flexible connection assembly.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a shock-resistant flexible hose connection assembly, comprising a flexible connector, both ends of which are provided with flexible snap-fit ​​joints, and an isolation sleeve is fitted over the flexible connector, with a plurality of shock-absorbing blocks evenly spaced along the circumferential direction on the surface of the isolation sleeve.

[0007] Furthermore, the flexible connector has a groove on its surface, and a rubber ring is embedded in the groove.

[0008] Furthermore, the flexible snap-fit ​​connector is fitted with a fixing sleeve, and multiple pressure blocks are evenly spaced along the circumference on the inner surface of the fixing sleeve. The fixing sleeve is fitted with a clamp, which is an open ring structure with a bolt threaded at the open end. Both ends of the bolt are threaded with nuts.

[0009] Furthermore, the side of the pressure block that contacts the flexible connector is provided with anti-slip texture.

[0010] Furthermore, the fixed base serves as a support structure for the flexible connector, with a support plate fixedly attached to its top, and limit rings clamped at both ends of the flexible connector.

[0011] Furthermore, mounting holes are provided at both ends of the fixing base and the limiting ring.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting a flexible snap-fit ​​connector, the elastic deformation capability is used to achieve quick insertion and connection with the hose, which is simple to operate and has high installation efficiency. In addition, a vibration isolation sleeve is set on the outside of the flexible connector, and multiple vibration-absorbing blocks are arranged on its surface to form a double vibration reduction structure. The vibration-absorbing blocks use their high damping characteristics to absorb external vibration energy and play a primary buffering role. The vibration isolation sleeve serves as a secondary vibration reduction structure, effectively isolating the vibration transmission path, thereby significantly reducing the dynamic stress on the connection part and improving the adaptability of the component in complex vibration environments.

[0013] 2. By setting up a fixing sleeve and pressure block structure, and cooperating with clamps, bolts and nuts to lock, the connection between the flexible clamp and the hose is reinforced for a second time, which effectively enhances the axial load-bearing capacity of the connection and prevents the connection from falling off due to external pulling or severe vibration.

[0014] 3. By setting up a fixed base and support plate structure, a stable support foundation is provided for the flexible connector. At the same time, limit rings are set at both ends of the flexible connector and the limit rings are fixed to the fixed base with screws to restrict the axial movement of the flexible connector, thereby further improving the structural stability and anti-displacement ability of the overall component.

[0020] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0021] Example 1: Please refer to Figure 1 and Figure 2 An anti-vibration flexible hose connection assembly includes a flexible connector 1, with flexible locking connectors 2 at both ends of the flexible connector 1. The flexible locking connectors 2 are made of elastic material and have good self-recovery properties, facilitating self-locking connection by their own elasticity after insertion into the hose. The surface of the flexible locking connector 2 has a groove 3, in which a rubber ring 4 is embedded. The rubber ring 4 is used to enhance the sealing and friction between the flexible locking connector 2 and the inner wall of the hose, preventing the connection from loosening or falling off under vibration or impact. The flexible connector 1 is covered with a vibration isolation sleeve 5, which is made of a composite material with certain rigidity and elasticity, used to isolate and weaken the transmission of external vibrations into the flexible connector 1. The surface of the vibration isolation sleeve 5 is evenly spaced with several shock-absorbing blocks 6 along the circumference. The shock-absorbing blocks 6 are made of polymer shock-absorbing material and have good energy absorption and buffering performance, effectively absorbing vibration and impact loads from the external environment.

[0022] During use, first, squeeze the flexible clamp 2 by hand to reduce its diameter. Then, insert the flexible clamps 2 at both ends of the flexible connector 1 into the two hose sections to be connected. After releasing, the flexible clamps 2 expand outwards due to their own elastic restoring force, tightly fitting the inner wall of the hose to achieve a stable connection. At this time, the rubber ring 4 further fits the inner wall of the hose, enhancing the sealing and pull-out resistance of the connection, preventing the connection from falling off due to vibration, impact, or pressure fluctuations. When the connection assembly is in a vibration or impact environment, the external vibration first acts on the shock-absorbing block 6. The shock-absorbing block 6 absorbs part of the vibration energy through the high damping characteristics of the material itself, playing a primary damping role. At the same time, the vibration isolation sleeve 5, as a secondary damping structure, can effectively block the further transmission of the remaining vibration energy, thereby reducing the dynamic stress borne by the connection between the flexible clamp 2 and the hose. Through the synergistic effect of the shock-absorbing block 6 and the vibration isolation sleeve 5, a dual damping protection mechanism is formed, significantly improving the stability and safety of the connection structure under complex working conditions, and effectively preventing risks such as hose connection failure, leakage, or detachment.

[0023] Example 2: Based on Example 1, please refer to... Figure 3 The flexible clamp connector 2 is fitted with a fixing sleeve 7. Three pressure blocks 8 are evenly spaced along the circumference on the inner surface of the fixing sleeve 7. These blocks are used to apply pressure to the connection between the flexible clamp connector 2 and the hose to enhance the stability of the connection. The side of the pressure block 8 that contacts the flexible clamp connector 2 is provided with anti-slip texture 12 to increase the friction between the pressure block 8 and the flexible clamp connector 2. The fixing sleeve 7 is fitted with a clamp 9. The clamp 9 is an open ring structure with a bolt 10 threaded at the open end. Both ends of the bolt 10 are threaded with nuts 11 for locking the clamp 9.

[0024] After the flexible clamp 2 and the hose are connected, the fixing sleeve 7 is placed on the connection part, so that the pressure block 8 fits tightly against the connection. Then, the clamp 9 is placed on the outside of the fixing sleeve 7, and the clamp 9 is tightened by rotating the bolt 10, thereby firmly fixing the fixing sleeve 7 in the connection position. Finally, the nut 11 is tightened to ensure that the entire structure is stable and reliable, and further improves the connection strength and vibration resistance between the flexible clamp 2 and the hose.

[0025] Please see Figure 4 The fixed base 13 serves as the support structure for the flexible connector 1. A support plate 14 is fixedly attached to its top for supporting and positioning the flexible connector 1. Limiting rings 15 are clamped at both ends of the flexible connector 1 to limit the axial displacement of the flexible connector 1. Mounting holes 16 are provided at both ends of the fixed base 13 and the limiting rings 15 to facilitate fixing with screws.

[0026] During installation, the flexible connector 1 is first placed on the support plate 14 of the fixed base 13, and limiting rings 15 are fitted on both ends of the connector. Then, screws are driven into the mounting holes 16 on the fixed base 13 and the limiting rings 15 to firmly fix the limiting rings 15 to both ends of the flexible connector 1. Finally, the fixed base 13 is fixed in the preset installation position, thereby achieving stable installation and reliable support for the entire connecting component.

[0027] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
