Description

Technical Field

[0001] The utility model belongs to the technical field of water hoses, in particular to a water hose interface protective cover. Background Art

[0002] With the continuous innovation and improvement of fire fighting technology, hose interfaces, as core components connecting water sources and fire fighting equipment, often face challenges of multiple complex environmental conditions in practical applications. Especially in the environment of high-pressure water flow, vibration is also a common problem of hose interfaces. At the fire fighting scene, due to the movement of fire fighting vehicles, the operation of water pumps and the impact of water flow, hose interfaces are easily affected by vibration. Long-term vibration will not only cause the interface to loosen, but also accelerate the wear of interface components, thereby increasing the risk of water leakage.

[0003] At the same time, the use of water hoses in fire fighting and rescue is not without difficulties. During emergency rescue, firefighters may need to move the water hoses quickly or lay water hoses on irregular terrain. These may cause unexpected impacts on the hose interfaces. Once the interfaces are impacted, their stability and safety may be seriously affected. Utility Model Content

[0004] The utility model provides a water hose interface protective cover, which aims to solve the challenges that water hose interfaces often face in high-pressure water flow and vibration environments. Vibration can cause the interface to loosen, accelerate wear, and increase the risk of water leakage. At the same time, in emergency rescue, quickly moving the water hose or laying it on irregular terrain may cause the interface to be impacted, affecting its stability and safety.

[0005] The utility model is implemented as follows: a water hose interface protection cover comprises an interface pipe body and a water outlet pipe; a protection mechanism is arranged on the outer side of the connection end of the interface pipe body and the water outlet pipe; the protection mechanism comprises: a limiting ring arranged on the outer side of the interface pipe body and the water outlet pipe, the limiting ring comprises two hinged semi-cylindrical ring bodies; a first fastener and a second fastener are arranged on the inner side of the limiting ring; wherein the first fastener comprises: a first fastening protrusion arranged on the inner side of the limiting ring, the first fastening protrusion is arranged in an annular shape; a plurality of extrusion springs arranged on the outer side of the first fastening protrusion, a plurality of the extrusion springs are each provided with a damper; a flexible pad arranged on the outer side of the plurality of extrusion springs, the outer surface of the flexible pad is provided with irregular anti-slip patterns.

[0006] Preferably, the second fastening member comprises: a second fastening protrusion arranged on the inner side of the limiting ring, the second fastening protrusion being arranged in a ring shape; and a plurality of limiting tooth blocks arranged on the outer side of the fastening protrusion.

[0007] Preferably, a fastening plate is provided on one side of the two ring bodies away from the hinge point, and a group of threaded holes is penetrated through the two fastening plates.

[0008] Preferably, it also includes a fastening bolt, which passes through two opposite threaded holes from top to bottom and is threadedly matched with a nut on one side.

[0009] Preferably, an annular limiting groove is provided at a middle position of the limiting ring, and the limiting groove is arranged between the first fastening protrusion and the second fastening protrusion.

[0010] Preferably, one end of the interface pipe body away from the water outlet pipe is connected to a water hose.

[0011] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0012] First, the device realizes the tight fixation of the connection part between the interface pipe body and the water outlet pipe, ensuring that the water hose interface will not loosen or fall off under high pressure or vibration, thereby ensuring the stability and safety of the water flow. The annular structure of the limiting ring enables it to be evenly stressed, while the first fastening protrusion and the extrusion spring provide uniform inward pressure, further enhancing the fastening of the interface. The second fastening protrusion and the limiting tooth block work together to generate sufficient friction force, so that the second fastening protrusion can be tightly fixed on the outside of the water outlet pipe. This fastening effect not only improves the reliability of the tight connection between the water hose interface and the water outlet pipe, but also reduces problems such as leakage or falling off caused by loose interfaces.

[0013] Second: This device effectively reduces the impact of external shock and vibration on the interface through the design of dampers and flexible pads. The damper can respond quickly and absorb impact energy, reducing the impact force of vibration on the interface, while the flexible pad uses its elasticity and friction to fit tightly on the surface of the interface pipe body and the outlet pipe, thereby enhancing the stability of the interface. At the same time, the irregular anti-slip texture on the outer surface of the flexible pad further increases the friction, preventing the protective cover from sliding under high-pressure water flow or external force. This design not only protects the integrity and functionality of the interface, but also improves the stability and safety of the entire water hose system. BRIEF DESCRIPTION OF THE DRAWINGS

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The utility model embodiment provides a hose interface protection cover, such as Figure 1-8 As shown, it includes an interface pipe body 1 and a water outlet pipe 2; a protective mechanism arranged on the outside of the connection end of the interface pipe body 1 and the water outlet pipe 2; the protective mechanism includes: a limit ring 3 arranged on the outside of the interface pipe body 1 and the water outlet pipe 2, the limit ring 3 includes two hinged semi-cylindrical ring bodies; a first fastener and a second fastener arranged on the inside of the limit ring 3; wherein the first fastener includes: a first fastening protrusion 4 arranged on the inside of the limit ring 3, the first fastening protrusion 4 is arranged in a ring shape; a plurality of extrusion springs 5 ​​arranged on the outside of the first fastening protrusion 4, and a damper is arranged in each of the plurality of extrusion springs 5; a flexible pad 6 arranged on the outside of the plurality of extrusion springs 5, and the outer surface of the flexible pad 6 is provided with irregular anti-slip patterns.

[0026] It should be noted that since the interface of the water hose 14 often faces challenges in high-pressure water flow and vibration environments, vibration can cause the interface to loosen, accelerate wear, and increase the risk of water leakage. At the same time, in emergency rescue, the rapid movement of the water hose 14 or the laying on irregular terrain may cause the interface to be impacted, affecting its stability and safety. This solution adopts a structure of a limit ring 3 composed of two semi-cylindrical rings to achieve a tight wrapping of the connection between the interface pipe body 1 and the water outlet pipe 2. At the same time, the setting of the first fastening protrusion 4 and the second fastening protrusion 7 enables the limit ring 3 to fit more closely to the outside of the interface pipe body 1 to ensure the stability and uniform force of the structure. In addition, considering the external impact and vibration that the interface of the water hose 14 may be subjected to, the design also adds components such as dampers and flexible pads 6, which can quickly respond to and absorb impact energy and reduce the impact of vibration on the interface; and the flexible pad 6, through its elasticity and friction, fits tightly to the surface of the interface pipe body 1 and the water outlet pipe 2, and provides an anti-slip function to prevent the protective cover from sliding.

[0027] Specifically, in this embodiment, the scheme mainly includes an interface pipe body 1 and a water outlet pipe 2; when the two semi-cylindrical ring bodies are closed, they are combined into a complete limiting ring 3, which can tightly wrap and fix the connection between the interface pipe body 1 and the water outlet pipe 2; on the inner side of the limiting ring 3, a first fastening protrusion 4 is designed, and this protrusion is arranged in a ring manner to ensure the stability and uniform force of the structure; the outer side of the first fastening protrusion 4 is equipped with an extrusion spring 5, which can generate a uniform inward pressure, so that the limiting ring 3 fits more closely to the outside of the interface pipe body 1, preventing the water hose 14 interface from loosening or falling off under high pressure or vibration;

[0028] At the same time, dampers are also arranged inside the extrusion spring 5, which play a vital role in the operation of the protective cover; when the interface of the water hose 14 is subjected to external impact or vibration, the damper can respond quickly, absorb and disperse part of the impact energy, and effectively reduce the impact of the vibration on the interface of the water hose 14, thereby protecting the integrity and functionality of the interface;

[0029] In addition, in order to further enhance the anti-slip performance of the protective cover, a flexible pad 6 is designed and installed on the outside of the extrusion spring 5; this flexible pad 6 has good elasticity and friction, and can fit tightly on the surface of the interface pipe body 1 and the water outlet pipe 2; and the irregular anti-slip texture on its outer surface further enhances the friction with the interface pipe body 1 and the water outlet pipe 2, effectively preventing the protective cover from sliding under high-pressure water flow or external force; this design ensures that the protective cover can always remain in the correct position, providing long-lasting and stable protection for the water hose 14 interface.
