Description

Technical Field

[0001] The invention relates to the technical field of braided hoses, and in particular to a braided hose assembly. Background Art

[0002] Braided hose is a hose with reinforcing material woven on the pipe. Generally speaking, metal hose is generally composed of three parts: bellows, mesh and joints. The bellows is the main body of the metal hose and plays a flexible role. The mesh plays a role of reinforcement and shielding. The joint plays a role of connection, etc. It is widely used in the connection of water supply and drainage.

[0003] Usually, braided hoses are mostly located inside walls or behind furniture, and water leakage is often not easy to be discovered, which may cause serious water damage and safety hazards; especially when conveying some special liquids, if the tube body ruptures and leaks, and it cannot be discovered in time, it may cause a safety accident. To this end, the present invention improves the water leakage problem caused by aging and rupture of the braided hose, so as to provide a braided hose assembly to avoid the risk of water leakage in the braided hose. Summary of the invention

[0004] The object of the present invention is to provide a braided hose assembly to solve the technical problem of preventing water leakage of the braided hose proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a braided hose assembly, comprising a braided hose, and a water inlet connector and a water outlet connector connected to both ends of the braided hose, the water inlet connector being provided with a water inlet regulating component, the water outlet connector being provided with a water outlet regulating component, a pressure transmission tube being connected between the water inlet regulating component and the water outlet regulating component, the pressure transmission tube being provided in the braided hose, and when the water outlet connector is in a closed state, the water outlet regulating component seals the water inlet regulating component through the pressure transmission tube to close the water inlet connector.

[0006] As a further solution of the present invention, the water inlet regulating assembly includes a first plug, one end of the first plug facing the braided hose is connected to a first piston, and the first piston is sealingly and slidably connected in a first connecting pipe.

[0007] As a further solution of the present invention, the water outlet regulating assembly includes a second plug, and the second plug is connected to a second piston at one end facing the braided hose, and the second piston is sealingly and slidably connected in the second connecting pipe.

[0008] As a further solution of the present invention, a first sealing limit ring is fixed on the inner side of the water inlet connector, which limits the first plug in the outward direction of the water inlet connector, and when the first plug is completely in contact with the first sealing limit ring, the water inlet connector is in a closed state.

[0009] As a further solution of the present invention, a second sealing limit ring is fixed on the inner side of the water outlet connection head, and the second sealing limit ring limits the second plug in the outward direction of the water outlet connection head, and when the second plug is completely abutted against the second sealing limit ring, the closed state of the water outlet connection head is achieved.

[0010] As a further solution of the present invention, the first connecting pipe and the second connecting pipe are sealed and connected at both ends of the pressure transmission pipe, and the first connecting pipe and the second connecting pipe are respectively fixed to the inner walls of the water inlet connector and the water outlet connector through supporting members.

[0011] As a further solution of the present invention, a first elastic member is disposed in the first connecting tube. The first elastic member is limited inside the first connecting tube. The first elastic member is in a compressed state and presses the first piston toward the first plug.

[0012] As a further solution of the present invention, a limiting ring is fixed in the water outlet connector, and a second elastic member is connected between the limiting ring and the end of the second plug in the water outlet direction.

[0013] As a further solution of the present invention, the pressure transmission tube is filled with liquid, and when the first piston moves toward the water outlet, the second piston is synchronously moved toward the water outlet by liquid pressure; or, when the second piston moves toward the water outlet, the first piston is synchronously moved toward the water inlet by liquid pressure.

[0014] As a further solution of the present invention, when the first plug and the second plug are simultaneously moved toward the water outlet, the water inlet connector and the water outlet connector are in an open state, and water flows through;

[0015] On the contrary, when the first plug and the second plug are moved toward the water inlet at the same time, the water inlet connector and the water outlet connector are simultaneously in a closed state, so that the braided hose is in a leak-proof state.

[0016] The beneficial effects of the present invention are:

[0017] 1. When the faucet or valve connected to the water outlet connector is opened, one end of the water outlet connector is in a negative pressure state relative to the water inlet connector. This is because there is water pressure in the water pipe connected to the water inlet connector. The elasticity of the first elastic member and the second elastic member is set according to the actual water pressure. Under the action of the water pressure, the first elastic member and the second elastic member can be compressed, so that the first plug and the second plug move toward the water outlet at the same time, thereby allowing the water to flow smoothly through the braided hose and out. When the faucet or valve connected to the water outlet connector is closed, the water outlet connector is closed, resulting in the same pressure in the braided hose, and the first elastic member and the second elastic member recover from the compressed state to the natural state, thereby pushing the first plug and the second plug to move toward the water inlet at the same time, so that the water inlet connector and the water outlet connector are in a closed state at the same time.

[0018] 2. The present invention can realize synchronous movement of the first plug and the second plug through the liquid hydraulic pressure of the pressure transmission pipe, thereby accurately controlling the water flow capacity of the braided hose. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1 In the first embodiment of the present invention, a braided hose assembly is provided, including a braided hose 100, and a water inlet connector 200 and a water outlet connector 300 connected to both ends of the braided hose 100, the water inlet connector 200 is connected to the water inlet pipeline, and the water outlet connector 300 is connected to the faucet or valve.

[0040] Among them, a water inlet regulating component 210 is arranged in the water inlet connector 200, a water outlet regulating component 310 is arranged in the water outlet connector 300, a pressure transmission pipe 400 is connected between the water inlet regulating component 210 and the water outlet regulating component 310, and the pressure transmission pipe 400 is arranged in the braided hose 100.

[0041] Since the water outlet connector 300 is connected to a faucet or a valve, the water outlet of the braided hose 100 is in a closed state. In order to avoid leakage of the braided hose 100 at the water outlet due to aging, rupture, etc., when the water outlet connector 300 is in a closed state, the water outlet regulating component 310 seals the water inlet regulating component 210 through the pressure transmission tube 400 to close the water inlet connector 200, thereby achieving closure at the water inlet connector 200, so that water no longer enters the braided hose 100 and no water leakage occurs.

[0042] For more specific implementation of the above solution, please refer to Figure 2and Figure 3 The water inlet regulating assembly 210 includes a first plug 211 , and one end of the first plug 211 facing the braided hose 100 is connected to a first piston 212 , and the first piston 212 is sealingly and slidably connected to the first connecting pipe 213 .

[0043] Please refer to Figure 2 and Figure 4 The water outlet regulating assembly 310 includes a second plug 311 , and one end of the second plug 311 facing the braided hose 100 is connected to a second piston 312 , and the second piston 312 is sealingly and slidably connected to the second connecting pipe 313 .

[0044] Please refer to Figure 2 and Figure 6 A first sealing limiting ring body 220 is fixed on the inner side of the water inlet connector 200. The first sealing limiting ring body 220 limits the first plug 211 in the outward direction of the water inlet connector 200, and when the first plug 211 completely abuts against the first sealing limiting ring body 220, the closed state of the water inlet connector 200 is achieved.

[0045] Please refer to Figure 2 and Figure 7 A second sealing limiting ring body 320 is fixed on the inner side of the water outlet connector 300, and the second sealing limiting ring body 320 limits the second plug 311 in the outward direction of the water outlet connector 300, and when the second plug 311 completely abuts against the second sealing limiting ring body 320, the closed state of the water outlet connector 300 is achieved.

[0046] The first connecting pipe 213 and the second connecting pipe 313 are sealed and connected to two ends of the pressure transmission pipe 400 .

[0047] refer to Figure 4-Figure 10 A first elastic member 214 is disposed in the first connecting tube 213 . The first elastic member 214 is limited inside the first connecting tube 213 . The first elastic member 214 is limited in a compressed state and presses the first piston 212 toward the first plug 211 .

[0048] A limiting ring body 330 is fixed inside the water outlet connector 300 , and a second elastic member 314 is connected between the limiting ring body 330 and the end of the second plug 311 in the water outlet direction.

[0049] In this embodiment, when the faucet or valve connected to the water outlet connector 300 is opened, one end of the water outlet connector 300 is in a negative pressure state relative to the water inlet connector 200. This is because there is water pressure in the water pipe connected to the water inlet connector 200. The elasticity of the first elastic member 214 and the second elastic member 314 is set according to the actual water pressure. Under the action of water pressure, the first elastic member 214 and the second elastic member 314 can be compressed, so that the first plug 211 and the second plug 311 move toward the water outlet at the same time, thereby allowing the water to flow smoothly through the braided hose 100 and out.

[0050] When the faucet or valve connected to the water outlet connector 300 is closed, the water outlet connector 300 is closed, causing the pressure in the braided hose 100 to be the same, and the first elastic member 214 and the second elastic member 314 recover from the compressed state to the natural state, thereby pushing the first plug 211 and the second plug 311 to move toward the water inlet at the same time, so that the water inlet connector 200 and the water outlet connector 300 are in the closed state at the same time.

[0051] refer to Figure 2 It is not difficult to find that after the first plug 211 blocks the water inlet connector 200 and the second plug 311 blocks the water outlet connector 300, the area inside the braided hose 100 and between the pressure transmission pipe 400 forms a closed space separately, while the water outlet connector 300, the pressure transmission pipe 400 and the water inlet connector 200 form a connected area by the second piston 312 and the first piston 212.

[0052] Thus, even if the braided hose 100 ruptures, as long as the valve connected to the water outlet connector 300 is closed, the movement of the second piston 312 is impossible, so that the water inlet connector 200 is always in a closed state, thereby avoiding water leakage caused by the rupture of the braided hose 100.

[0053] Based on the characteristics of the movement of the first plug 211 and the second plug 311 in the above embodiment, it is obvious that synchronization is required. Usually, hydraulic pressure can avoid space compression such as air pressure, which causes asynchronous movement. To this end, in another embodiment of the present invention, the pressure transmission tube 400 is filled with liquid, and when the first piston 212 moves toward the water outlet, the second piston 312 moves synchronously toward the water outlet through the liquid pressure; or when the second piston 312 moves toward the water outlet, the first piston 212 moves synchronously toward the water inlet through the liquid pressure.

[0054] When the first plug 211 and the second plug 311 move toward the water outlet at the same time, the water inlet connector 200 and the water outlet connector 300 are in an open state, and water flows through;

[0055] On the contrary, when the first plug 211 and the second plug 311 move toward the water inlet at the same time, the water inlet connector 200 and the water outlet connector 300 are simultaneously in a closed state, so that the braided hose 100 is in a leak-proof state.

[0056] The first connecting pipe 213 and the second connecting pipe 313 are respectively fixed to the inner walls of the water inlet connector 200 and the water outlet connector 300 through the supporting member 500 .

[0057] In this embodiment, the first plug 211 and the second plug 311 can be synchronously moved by the liquid hydraulic pressure of the pressure transmission tube 400, thereby accurately controlling the water flow capacity of the braided hose 100. The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, shall be covered within the protection scope of the present invention.
