Description

Technical Field

[0001] The utility model relates to the technical field of water delivery equipment, in particular to a water hose with a quick-insert connector. Background Art

[0002] Water hoses are used to transport high-pressure liquids such as water and foam. They are typically constructed by bending and circumferentially overlapping flat composite wall materials into a tubular shape. The overlapping tubular composite wall material is called the "tube wall." Water hoses are commonly used in agricultural irrigation, urban landscaping, aquaculture, and firefighting water supply.

[0003] In the existing technology, when connecting branch water pipes to water hoses, screw-in clamping or screw-in threaded connection is usually adopted. These connection methods can meet the needs of connecting water hoses and branch water pipes to a certain extent, but there are still certain shortcomings in actual use. The screw-in clamping and screw-in threaded connections need to be rotated to achieve alignment, which requires high accuracy and strength of the operator. Especially in an emergency, it is difficult to quickly complete the quick connection between the water hose and the branch water pipe, and it is relatively inconvenient to use. Utility Model Content

[0022] The present invention will be further described below with reference to the following embodiments and the accompanying drawings.

[0023] refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 A water hose with a quick-connect connector includes a water hose body 1, an interface component 2, and a branch pipe 3. The water hose body 1 is provided with at least one through hole 101 running through its side wall. The interface component 2 includes an inner interface ring 21, an outer interface ring 22 and a sealing ring 23. The upper part of the inner interface ring 21 extends into the through hole 101 and does not extend out of the outside of the water hose body 1. A connecting ring 211 is provided on the upper part of the inner interface ring 21. The connecting ring 211 is connected to the inner wall of the water hose body 1 by ultrasonic welding.

[0024] A coaxial docking ring 224 is formed at the lower portion of the outer interface ring 22. The outer diameter of the docking ring 224 is smaller than that of the outer interface ring 22. A docking groove 212 is defined on the inner wall of the inner interface ring 21. The docking ring 224 engages with the docking groove 212, creating a plug-and-sleeve fit between the outer interface ring 22 and the inner interface ring 21. A sealing ring 23 is provided on the inner wall of the inner interface ring 21. A stepped surface 6 is formed between the docking ring 224 and the outer interface ring 22. The top surface of the inner interface ring 21 and / or the inner wall of the docking groove 212 are ultrasonically welded to the stepped surface 6. Preferably, the upper end surface of the inner interface ring 21 is ultrasonically welded to the lower end surface of the outer interface ring 22.

[0025] The upper end face of the inner interface ring 21 is adapted to the outer surface of the hose body 1. When the outer interface ring 22 is docked with the inner interface ring 21, the lower part of the outer interface ring 22 abuts against the outer surface of the hose body 1, ensuring the connection sealing between the hose body 1 and the interface assembly 2.

[0026] The inner wall of the outer interface ring 22 is adapted to the inner wall of the inner interface ring 21 to form a straight insertion channel 4 for the branch pipe 3 to be inserted. Preferably, the axial length of the docking ring 224 is smaller than the axial length of the docking groove 212, so that an accommodation space 5 for the sealing ring 23 to be embedded is formed between the docking ring 224 and the docking groove 212, thereby positioning the sealing ring 23 in the straight insertion channel 4.

[0027] Two abutment platforms 301 are symmetrically provided on the outer wall of the branch pipe 3 . The abutment platforms 301 are provided with outer protrusions 302 . An inner concave cavity 303 is formed on the outer wall of the branch pipe 3 above the abutment platforms 301 .

[0028] Two elastic buckles 221 are symmetrically provided on the upper portion of the outer interface ring 22 . A hook portion 222 is formed at the end of the elastic buckle 221 . Two inclined surfaces 223 are formed on opposite sides of the two hook portions 222 . The two inclined surfaces 223 are symmetrically provided on the left and right. During the process of inserting the branch pipe 3 into the straight-insertion channel 4, the abutment 301 and its corresponding inclined surface 223 come into contact. Guided by the inclined surface 223, the elastic buckle 221 is compressed and deformed to facilitate smooth insertion of the branch pipe 3 into the straight-insertion channel 4. When the position between the inner concave cavity 303 and the hook portion 222 corresponds, the outer wall of the branch pipe 3 and the inner wall of the sealing ring 23 are tightly abutted. The sealing ring 23 is used to seal the connection between the straight-insertion channel 4 and the branch pipe 3. The elastic buckle 221 recovers its deformation, and the hook portion 222 is inserted into the inner concave cavity 303. The top surface of the outer boss 302 and the bottom surface of the hook portion 222 are tightly abutted, thereby achieving a snap connection between the elastic buckle 221 and its corresponding abutment 301, completing the straight-insertion snap connection between the branch pipe 3 and the outer interface ring 22. Preferably, the branch pipe 3 can be a pipe fitting such as an elbow pipe, a tee pipe, or a tee valve.

[0029] During use, the branch pipe 3 and the hose body 1 can be disassembled and assembled as needed, which is convenient for operation and ensures the stability and sealing of the connection, making it more convenient to use.

[0030] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
