[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0013] Reference Figure 1-3 A leak-proof hose assembly includes a protective hose outer layer 1, a wire mesh layer 11 installed inside the protective hose outer layer 1, a braided layer 12 installed inside the wire mesh layer 11, the braided layer 12 being tightly installed with the hose inner layer 2 via a sealing adhesive layer 21, connectors 3 being installed at both ends of the protective hose outer layer 1, the inner shaft of the connector 3 being installed inside the hose inner layer 2, the outer side of the inner shaft of the connector 3 being installed on the outer wall of the protective hose outer layer 1, and a locking ring 4 being installed at the outer end of the connector 3, the locking ring 4 being used to install the connector 3 at the outer end of the protective hose outer layer 1 via bolts 51 and locking nuts 52.

[0014] A sealing ring 31 is provided between the inner shaft and the outer end wall of the connector 3. The sealing ring 31 inside the connector 3 fits with the end face of the hose, which increases the sealing performance between the inner end face of the outer layer 1 of the protective hose and the inside of the connector 3.

[0015] Meanwhile, two fixing seats 41 are installed on the upper end of the locking ring 4, and a bolt 51 is installed in the middle of the fixing seat 41. The function of the two fixing seats 41 is to support the installation of the bolt 51. The locking ring 4 is elastic and can be tightened inward.

[0016] Furthermore, the bolt 51 has a thread at its front end, and the locking nut 52 has a thread inside that matches the bolt 51. Rotating the locking nut 52 causes it to tighten inward, thus securing the bolt 51 in place. The locking ring 4 secures the connector 3 to the outer end of the outer layer 1 of the protective hose.

[0017] Among them, the outer layer 1 of the protective hose is made of rubber wear-resistant hose, the steel wire mesh layer 11 is made of stainless steel wire braiding, and the braided layer 12 is made of high-strength aramid fiber. The outer layer 1 of the protective hose can protect the internal materials from external wear. The steel wire mesh layer 11 has the characteristic of high strength. The steel wire mesh layer 11 further improves the strength of the hose. The braided layer 12 is attached to the inner layer 2 of the hose, which increases the overall tensile performance of the hose.

[0018] Meanwhile, a sealant layer 21 is provided between the inner layer 2 of the hose and the braided layer 12. The sealant layer 21 is made of a highly viscous sealant. The sealant layer 21 improves the sealing between the inner layer 2 of the hose and the outer layer 1 of the protective hose, so that the liquid inside the inner layer 2 of the hose will not leak to the outer layer 1 of the protective hose.

[0019] In this embodiment, when a hose needs to be installed, the inner layer 2 of the hose is first tightly bonded to the braided layer 12 via the sealant layer 21. The sealant layer 21 improves the sealing between the inner layer 2 of the hose and the outer protective hose layer 1. Then, a wire mesh layer 11 is installed on the outer end of the braided layer 12. These two layers greatly enhance the strength and tensile length of the hose. The outer protective hose layer 1 is installed on the outer end of the wire mesh layer 11. The outer protective hose layer 1 is made of rubber wear-resistant hose, which has the characteristics of high wear resistance and high strength. Connectors are installed at both ends of the outer protective hose layer 1. The connector 3 is installed inside the inner layer 2 of the hose. A locking ring 4 is installed on the outer end of the connector 3. Rotating the locking nut 52 causes the locking nut 52 to tighten inward. The locking nut 52 is fixed to the bolt 51. The locking ring 4 fixes the connector 3 to the outer end of the outer layer 1 of the protective hose. A sealing ring 31 is provided inside the connector 3. The sealing ring 31 fits with the end face of the hose, which increases the sealing between the inner end face of the outer layer 1 of the protective hose and the inside of the connector 3. The hose with the connectors 3 installed at both ends is connected to the place where it is needed.

[0020] In this invention, the hose is made of steel wire mesh layer 11 and braided layer 12, which gives it high wear resistance and high strength, so that the hose will not easily break and cause liquid leakage. In addition, a locking device is installed at the connection between the connector 3 and the outer layer 1 of the protective hose, which further improves the sealing of the connection and reduces the risk of leakage.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
