[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1 、 Figure 2 As shown, the utility model provides a lightweight water hose that is easy to connect and disassemble, including a fire hydrant joint mechanism 1, a fabric water hose mechanism 2 is provided on the rear side of the fire hydrant joint mechanism 1, the fire hydrant joint mechanism 1 includes a metal joint ring 11, an extension ring 12 is fixedly installed on the rear side of the metal joint ring 11, the inner ring of the extension ring 12 is provided with an extension ring thread wall 13, an inner ring of the metal joint ring 11 is fixedly installed with an inner ring 14, an inner ring of the inner ring 14 is fixedly installed with an inner extension ring 15, the front side of the inner extension ring 15 extends to the rear side of the inner ring 14, and the outer wall of the inner extension ring 15 extends through the rear side of the inner ring 14 and is provided with a threaded wall 16;

[0021] The metal joint ring 11 is made of metal material as a whole and is used to connect to the water outlet of the fire hydrant. The other end of the fabric water hose mechanism 2 used to connect to the sprinkler head is also connected to the metal joint ring 11. Their internal structures are the same. When connected, the double connection protection of the extension ring 12 and the built-in extension ring 15 improves the sealing performance without affecting the disassembly and assembly of the fabric water hose mechanism 2.

[0022] like Figure 3 As shown, an embedding groove 141 is formed on the rear side of the built-in ring 14, a hook surface 142 of a hook and loop surface 142 is fixedly bonded to the rear side of the hook and loop surface 142, a fleece surface 143 of a hook and loop surface 143 is fixedly bonded to the rear side of the fleece surface 143, and a sealing rubber ring 144 is fixedly bonded to the rear side of the fleece surface 143. The sealing rubber ring 144 is located between the extension ring 12 and the built-in extension ring 15;

[0023] When the sealing rubber ring 144 used to improve the sealing performance becomes aged and broken after repeated disassembly and assembly, it can be torn off by utilizing the adhesive connection between the Velcro hook surface 142 and the Velcro fur surface 143 in the embedded groove 141. Since the space between the extension ring 12 and the built-in extension ring 15 is small, it can be torn off with the help of a hook or other tool, which facilitates replacement, ensures the sealing effect, and prevents water leakage.

[0024] like Figure 4 、 Figure 5 As shown, the fabric water hose mechanism 2 includes a water hose body 21, a bearing ring 22 is fixedly installed on the inner ring of the front end of the water hose body 21, a joint mounting ring 23 is fixedly installed on the inner ring of the bearing ring 22, a water hose quick-release joint 24 is fixedly installed on the front end of the joint mounting ring 23, a joint thread wall 241 is provided on the outer wall of the water hose quick-release joint 24, and the joint thread wall 241 is threadedly connected to the extension ring thread wall 13 provided on the inner ring of the extension ring 12, and a sealing ring 242 is fixedly installed on the rear side of the outer wall of the water hose quick-release joint 24 The inner ring of the water hose quick-release joint 24 is fixedly installed with a built-in extension ring 243. The built-in extension ring 243 communicates with the inner cavity of the water hose body 21 through the joint installation ring 23. The inner ring of the built-in extension ring 243 is provided with a threaded wall 244. The built-in extension ring 243 is threadedly connected to the built-in extension ring 15 through the threaded connection between the threaded wall 244 and the threaded wall 16. After the built-in extension ring 243 is threadedly connected to the built-in extension ring 15, its front end overlaps the rear side of the sealing rubber ring 144.

[0025] By aligning the water hose quick-release joint 24 with the inner ring of the extension ring 12 and rotating it, the water hose quick-release joint 24 is tightened by utilizing the threaded connection between the joint threaded wall 241 opened on the outer wall of the water hose quick-release joint 24 and the extension ring threaded wall 13 opened on the inner ring of the extension ring 12. At the same time of rotation and tightening, the built-in extension ring 243 will also utilize the threaded wall 244 opened on the inner ring to threadedly connect and tighten with the threaded wall 16 opened on the outer wall of the built-in extension ring 15, thereby forming a double seal. The overall water hose quick-release joint 24 can rotate by utilizing the rotation of the inner ring of the bearing ring 22 at the front end of the inner wall of the water hose body 21 of the joint mounting ring 23, so as to avoid the water hose body 21 from rotating with the water hose quick-release joint 24 and causing entanglement. After tightening, the front end of the built-in extension ring 243 will squeeze the sealing rubber ring 144 to achieve a first layer of sealing, and the sealing ring 242 on the rear side of the outer wall of the water hose quick-release joint 24 will squeeze the inner ring of the extension ring 12 to form a second layer of sealing, thereby effectively preventing water leakage.

[0026] The working principle of this easy-to-connect and disassemble lightweight water hose will be described in detail below.

[0027] like Figure 1-5As shown, when the fabric water hose mechanism 2 needs to be connected to the fire hydrant joint mechanism 1, the water hose quick-release joint 24 is aligned with the inner ring of the extension ring 12 and rotated, thereby utilizing the threaded connection between the joint thread wall 241 opened on the outer wall of the water hose quick-release joint 24 and the extension ring thread wall 13 opened on the inner ring of the extension ring 12 to tighten. At the same time, the built-in extension ring 243 will also utilize the threaded connection between the threaded wall 244 opened on the inner ring and the threaded wall 16 opened on the outer wall of the built-in extension ring 15 to form a double seal. After tightening, the front end of the built-in extension ring 243 will squeeze the sealing rubber ring 144 to achieve a layer of sealing. The sealing ring 242 on the rear side of the outer wall of the water hose quick-release joint 24 will squeeze the inner ring of the extension ring 12 to form a second layer of seal, thereby effectively preventing water leakage. The overall water hose quick-release joint 24 can rotate by utilizing the rotation of the inner ring of the bearing ring 22 at the front end of the inner wall of the water hose body 21 using the joint mounting ring 23, thereby preventing the water hose body 21 from rotating with the water hose quick-release joint 24 and causing entanglement. When the water hose body 21 needs to be carried, the overall water hose quick-release joint 24 can be reversed to quickly separate and disassemble it from the metal joint ring 11, thereby detaching from the relatively bulky fire hydrant joint mechanism 1, saving storage space and making it more convenient to carry.

[0028] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
