Abstract
Description
Technical Field
[0001] This utility model relates to the field of flat plate support frame technology, and in particular to a shockproof flexible hose. Background Technology
[0002] In industrial production, the continuous vibrations generated by equipment such as pumps and compressors during operation are transmitted through pipelines, leading to loosening of pipeline joints, fatigue damage, and even safety accidents such as media leakage. In building water supply and drainage, heating and ventilation, the thermal expansion and contraction of pipelines caused by temperature changes, as well as the positional displacement caused by building settlement, can also cause continuous stress on the connection structure of rigid pipelines. In earthquake-prone areas, strong ground vibrations can directly cause rigid pipelines to break, paralyzing critical infrastructure such as water supply, gas, and electricity, and triggering secondary disasters. Therefore, shock-resistant flexible hoses have emerged.
[0003] Vibration-resistant flexible hoses are pipe fittings with elasticity and flexibility. They mainly absorb and buffer vibrations and displacements through their own deformation, protecting the safe and stable operation of pipelines and related equipment. They can absorb vibrations generated during the operation of industrial equipment and building water supply and drainage systems through their elastic structure, preventing vibration propagation to reduce noise and pipeline damage risks. They can flexibly compensate for axial, lateral, or angular displacements caused by temperature changes, foundation settlement, etc., relieve pipeline stress, ensure connection sealing and structural integrity, isolate the mechanical impact of pipelines on equipment interfaces, protect internal parts of equipment, and extend service life.
[0004] Traditional shock-resistant hoses cannot be connected, which greatly limits their flexibility. When faced with complex pipeline layouts or mismatched lengths, either custom lengths need to be made, increasing costs and time, or non-shock-resistant pipe fittings are used for splicing, which compromises the overall shock-resistant performance. During maintenance and replacement, even if only a part is damaged, the entire hose needs to be replaced. This is especially true for long-distance or large-size hoses, which significantly increases material and labor costs and causes waste. Therefore, a shock-resistant hose is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a shock-absorbing hose, which aims to improve the problem that existing shock-absorbing hoses cannot be connected and are inconvenient to maintain and replace.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a shock-absorbing flexible hose, comprising a flexible hose one, a fixed shaft one fixedly connected to one end of the flexible hose one, a conical body fixedly connected to the outside of the fixed shaft one, an installation column fixedly connected to the outside of the conical body, a limit tube slidably connected inside the installation column, a fixed shaft two fixedly connected to the other end of the limit tube, a flexible hose two fixedly connected to the other end of the fixed shaft two, and a shock-absorbing component installed on the outside of the flexible hose two;

[0023] 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.
[0024] Reference Figures 1 to 3 This utility model provides an embodiment of a shockproof flexible hose, including a flexible hose 1, which serves as the basic channel for medium transportation. One end of the flexible hose 1 is fixedly connected to a fixed shaft 2, and a conical body 3 is fixedly connected to the outside of the fixed shaft 2. The fixed shaft 2 serves to stably connect the flexible hose 1 and the conical body 3, and can stably transmit the force on the flexible hose 1 to the conical body 3, ensuring the structural strength of the connection. An installation post 4 is fixedly connected to the outside of the conical body 3, and a limit tube 19 is slidably connected inside the installation post 4. The conical structure of the conical body 3 can guide the sliding of the limit tube 19 during the docking process, so that the limit tube 19 can slide accurately into the installation post 4, improving the convenience of docking.
[0025] The mounting post 4 has two spherical slots 18 on its exterior. Two spheres 24 are slidably connected inside each of the two spherical slots 18. The mounting post 4 provides a sliding track for the limiting tube 19. Its internal structure constrains the sliding direction of the limiting tube 19, ensuring that the limiting tube 19 moves along a predetermined trajectory during docking, thus guaranteeing the stability of the docking process. When the limiting tube 19 slides inside the mounting post 4, it drives the two spheres 24 to slide outwards within the two spherical slots 18, creating conditions for subsequent fixing actions and promoting the orderly progress of the docking process. A fixed shaft 6 is fixedly connected to the other end of the limiting tube 19, and a flexible hose 7 is fixedly connected to the other end of the fixed shaft 6. The fixed shaft 6 connects the limiting tube 19 and the flexible hose 7, transmitting the movement of the limiting tube 19 to the flexible hose 7 while ensuring the stability of the flexible hose 7 during docking, thus ensuring smooth media flow after docking.
[0026] Hose 2 7 and hose 1 together form a complete medium transport channel. Its connection with fixed shaft 2 6 allows hose 2 7 to adjust its position synchronously with the movement of limit tube 19, facilitating precise docking with hose 1 1. Hose 2 7 is equipped with a shock-absorbing component on its exterior. When subjected to external force, the shock-absorbing component can absorb vibration energy through elastic deformation, converting rigid transmission into elastic buffering, effectively reducing the transmission of vibration to pipelines, equipment and fixed structures, and improving the overall shock absorption effect. A sliding column 11 is fixedly connected inside the cone-shaped body 3. A sliding rod 13 is slidably connected inside the sliding column 11. A spring 16 is sleeved on the exterior of the sliding rod 13. The sliding column 11 provides a stable sliding space for the sliding rod 13, which can constrain the sliding direction of the sliding rod 13, ensuring that the sliding rod 13 moves in a straight line when subjected to force, and ensuring the stability of the deformation of the spring 16.
[0027] A limiting post 12 is fixedly connected to the right side of the sliding post 11. The limiting post 12 can limit the maximum sliding distance of the sliding rod 13, preventing the sliding rod 13 from sliding excessively and causing the spring 16 to exceed its elastic limit and be damaged, thus ensuring the service life of the structure. When the sliding rod 13 slides inside the sliding post 11, it will drive the spring 16 to compress. The elastic deformation of the spring 16 converts the impact force during docking into elastic potential energy, realizing flexible buffering during docking and reducing component wear. When the sliding rod 13 slides, the spring 16 is compressed, and the elastic force generated can act in the opposite direction on the sliding rod 13 to buffer the impact force during docking. At the same time, it can assist the components to reset after docking, ensuring the tightness of the docking. The other end of the sliding rod 13 is fixedly connected to the connecting post 14, and the other end of the connecting post 14 is fixedly connected to the docking shaft 15. The connecting post 14 can transmit the thrust received by the docking shaft 15 to the sliding rod 13, causing the sliding rod 13 to drive the spring 16 to compress, realizing the effective transmission and buffering of docking force, and ensuring the smooth docking process.
[0028] Reference Figure 1 and Figure 4 The vibration damping assembly includes two mounting shafts 8, which serve as key nodes for vibration transmission. Both shafts are externally fixed to the outside of the second hose 7, effectively transmitting vibrations from the second hose 7 to themselves and laying the foundation for subsequent vibration damping. The two mounting shafts 8 are internally connected to an outer sleeve 9. This movable connection allows the outer sleeve 9 to move flexibly relative to the mounting shafts 8 when under force, ensuring that the outer sleeve 9 can smoothly transmit pressure to the mounting shafts 8, while also leaving room for subsequent elastic deformation.
[0029] The outer sleeve 9 is externally connected to a bellows 10. When an external force is applied to the shock absorber ring, the bellows 10 will be compressed first. Through this movable connection, the pressure is efficiently transmitted to the outer sleeve 9. It can also directly participate in the absorption of vibration energy through elastic deformation such as stretching, compression, and bending. The inner sleeve 26 is internally connected to the outer sleeve 9. The inner sleeve 26 can provide stable guidance for the elastic deformation of the outer sleeve 9, preventing the outer sleeve 9 from shifting or getting stuck during stretching and compression, ensuring that it smoothly transmits the pressure to the mounting shaft 8, thereby completing the absorption and buffering of vibration energy.
[0030] Reference Figure 2 and Figure 3 The mounting post 4 is externally fixedly connected to a limiting ring 17, and externally slidably connected to a limiting shaft 5, allowing the limiting shaft 5 to move axially along the outside of the mounting post 4. This lays the foundation for subsequently driving the ball 24 to be positioned and to cooperate with the limiting ring 17 to complete the docking and fixing. An elastic ring 25 is installed inside the limiting shaft 5. When the limiting shaft 5 slides, the elastic ring 25 will stretch accordingly, thereby storing elastic potential energy and providing elastic support for the reset or maintaining a stable state of the limiting shaft 5. The limiting ring 17 can block the sliding limiting shaft 5. When the limiting shaft 5 slides to contact the limiting ring 17, it will stop, thereby ensuring the accurate sliding position of the limiting shaft 5 and ensuring the smooth completion of the docking process.
[0031] A sliding rod 20 is slidably connected inside the fixed shaft 2 6. A spring 23 is sleeved on the outside of the sliding rod 20, allowing the sliding rod 20 to slide axially inside the fixed shaft 2 6. This provides a structural basis for the subsequent compression of the spring 23 and the transmission of docking force through its sliding motion. When the sliding rod 20 slides, it will compress the spring 23. During the compression process, the spring 23 will store elastic potential energy, which can play a buffering role during docking and also provide power for the subsequent reset of the components. The other end of the sliding rod 20 is fixedly connected to a connecting post 21, and the other end of the connecting post 21 is fixedly connected to a docking shaft 22. The connecting post 21 serves to connect the sliding rod 20 and the docking shaft 22, and can transmit the sliding force of the sliding rod 20 to the docking shaft 22, ensuring the effective transmission of force.
[0032] The second docking shaft 22 is one of the key components for realizing pipe docking. Through its interaction with the first docking shaft 15, it can transmit the thrust during docking and drive the entire docking process. The external sliding connection of the second docking shaft 22 is inside the limiting tube 19, allowing the second docking shaft 22 to slide inside the limiting tube 19. This provides sliding guidance for the second docking shaft 22 and indirectly controls the position of the second docking shaft 22 through the movement of the limiting tube 19.
[0033] The spherical groove 18 provides sliding space and limit for the ball 24, allowing the ball 24 to slide stably inside and outside, thereby locking and unlocking the limit tube 19. The sliding of the ball 24 in the spherical groove 18 can cooperate with the movement of the limit tube 19 and the limit shaft 5. When the ball 24 slides outward, it can release the restriction on the limit tube 19. When it slides inward to the groove outside the limit tube 19, it can lock the limit tube 19, ensuring the stability after docking.
[0034] Working principle: When the shock-absorbing hoses need to be connected, the limiting tube 19 slides into the mounting post 4. When the limiting tube 19 slides inside the mounting post 4, it drives the two balls 24 to slide outward inside the two spherical slots 18. Subsequently, the connecting shaft 22 pushes the connecting shaft 15 to slide. Since the forces are mutual, the connecting shaft 15 also pushes the connecting shaft 22 to slide. When the connecting shaft 15 slides, it drives the connecting post 14 to slide. When the connecting post 14 slides, it drives the sliding rod 13 to slide. When the sliding rod 13 slides, it compresses the spring 16. When the connecting shaft 22 slides, it drives the connecting column 21 to slide. When the connecting column 21 slides, it drives the sliding rod 20 to slide. When the sliding rod 20 slides, it drives the spring 23 to compress. At this time, the limiting shaft 5 slides to the right. When the limiting shaft 5 slides, it drives the elastic ring 25 inside the limiting shaft 5 to stretch. When the two protrusions at the bottom of the limiting shaft 5 slide on the two grooves outside the mounting column 4, it drives the two balls 24 to slide towards the middle. When the two balls 24 slide to the two grooves outside the limiting tube 19, the limiting shaft 5 contacts the limiting ring 17 and stops sliding, completing the pipe connection.
[0035] When the shock-absorbing ring comes into contact with an external force, the bellows 10 will be squeezed, transmitting the pressure to the outer sleeve 9. The outer sleeve 9 then transmits the pressure to the two mounting shafts 8. At this time, the two mounting shafts 8 drive the bellows 10 to undergo elastic deformation such as stretching, compression, and bending through the outer sleeve 9 to absorb vibration energy, transforming the original rigid transmission into elastic buffering, thereby reducing the transmission of vibration to pipelines, equipment and fixed structures.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
