DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

[0017] Please refer to FIG. 1-4. A connector for a hose comprises a first connecting end 10, a second connecting end 20 and a combining tube 30. The first connecting end 10 has a main body 11 with a cap shape, a neck portion 12 and an inserting section 13 at a bottom end of the main body 11, the inserting section 13 has a screw hole 14 connected through the main body 11 and a plurality of engaging protrusions 15 on a circumference of the neck portion 12. The second connecting end 20 has a threaded section 21 on a circumference thereof, a circular stopping neck 22 internally defining an upper space 23 and a lower space 24, a plurality of vertical ribs 25 evenly disposed on a sidewall of the lower space 24, and a plurality of engaging grooves 26 disposed on a top edge of the upper space 23. The direct exposure of the engaging grooves 26 and the engaging protrusion 15 provides visual judgment, so that the first connecting end 10 and the second connecting end 20 can be completed more conveniently and quickly. The combining tube 30 has a threaded section 31 on a circumference thereof and an enlarged flange 32 at a bottom end. The combining tube passes through the stopping neck 22 of the second connecting end 20, and the threaded section 31 of the combining tube 30 engages with the screw hole 14 of the first connecting end 10 in the upper space 23. With the mutual restriction of the stopping neck 22 and the flange 32, the combining tube 30 is prevented from directly moving up and detaching from the second connecting end 20, so that the second connecting end 20 can rotate relatively around combination of the first connecting end 10 and the combining tube 30.

[0018] Furthermore, the main body 11 of the first connecting end 10 is a hand screw cap

[0019] Moreover, the screw hole 14 of the first connecting end 10 has a hexagonal engaging portion for engaging with a hand tool to rotatably drive the first connecting end 10.

[0020] In addition, the main body 11 of the first connecting end 10 is a hand screw cap, and the screw hole 14 has a hexagonal engaging portion such that the first connecting end 10 can be rotated manually or by a hand tool.

[0021] Also, the inserting section 13 of the first connecting end 10 is sleeved with at least one sealing ring 16

[0022] Likewise, the combining tube 30 has a hexagonal engaging portion for engaging with a hand tool to rotate the combining tube 30.

[0023] In actual use, the main body 11 of the first connecting end 10 and the threaded section 21 of the second connecting end 20 are respectively attached with a spray gun 40 and a water hose 50, and the second connecting end 20 is completely concealed in a pipe joint 51 of the water hose 50, as shown in FIG. 5, which greatly shorten the exposed length of connector. With the rotatable combination of the first connecting end 10 and the second connecting end 20, as, shown in FIG. 6, the water pipe 50 is free from twisting and winding during the pulling process of the water spray, which greatly improves the convenience of watering operation. Also, please refer to FIG. 7, in order to disassemble the connector, the user holds the main body 11 of the first connecting end 10 and pushes it directly to the second connecting end 20, so that the engaging protrusion 15 of the first connecting end 10 is visually engaging with engaging groove 26 of the second connecting end 20; when the engaging protrusion 15 engages with the engaging groove 26, by rotating the first connecting end 10, the second connecting end 20 can be locked or released so it is easy to disassemble and replace the connector with the water pipe 50.

[0024] With the structure of the above specific embodiment, the following benefits can be obtained: The engaging protrusion 15 and the engaging groove 26 are directly exposed foe visual judgment, so the combination of the first connecting end 10 and the second connecting end 20 can be completed quickly one-time without having to make multiple blind attempts. Also, the vertical ribs 25 provide guidance when the combining tube 30 is inserted or moved down by the first connecting end 10, and then the vertical ribs 25 also prevent the flange 32 and the lower space 24 from making a full circle of direct contact, which can effectively reduce the frictional resistance between the two, so that the connector can allow smooth anti-entanglement rotation.

[0025] Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
