BACKGROUND OF INVENTION

Field of Invention

The present invention relates to a hose connecting device, and more particularly to a rotatable hose connecting device.

Description of Related Art

A conventional connector structure of water pipe is shown inFIGS. 9 and 10. It mainly includes a female connector60, a male connector70and a tubal body80. The female connector60includes an assembling sleeve61and a connector62. The assembling sleeve61is provided with a through hole, passes through the inserting section621of the connector62, and is inserted into one end of a tubal body80. The assembling sleeve61is further provided with an inner threaded section611. The male connector70has an assembling portion71and an inserting portion72, and the assembly portion71is provided with the outer threaded section711. Furthermore, the inserting portion72is inserted at the other end of a tubal body80to assemble the female connector60and the male connector70on both ends of the tubal body80respectively.

When the user wants to connect the tubal body80to a faucet and a water outlet unit, the assembling sleeve61of the female connector60is inserted and fixed to the end of the tubal body80through the connector62, the assembling sleeve61is inserted and fixed. The assembling sleeve61is tightly pressed by the connector62and difficult to rotate freely, in order to assemble onto the faucet, the connector62pushes inward and squeezes the assembling sleeve61even more, resulting in the assembling sleeve61cannot rotate at all. Meanwhile, the tubal body80might be rotated and wound at the same time during the assembly process, which causes assembly problems. Moreover, the assembly part711and the inserting portion72of the male connector70are integrally formed. Similarly, when the inserting portion72is inserted and fastened into one end of the tubal body80, the assembly part711is fixed with the inserting section72and cannot rotate freely when the tubal body80is rotated and wound during the assembly process, resulting in assembly troubles. In summary, the prior art connector often causes the tubal body80to become knotted and entangled, which not only stops water output and also increases the difficulty of winding the tubal body80without knots and entanglement. Also, the resistance caused by entanglement increases the internal pressure of the tubal body80and makes the tubal body80easy to burst or the tubal body80to be detached from the water supply equipment.

Therefore, it is desirable to provide a hose connecting device to mitigate and/or obviate the aforementioned problems.

SUMMARY OF INVENTION

An objective of present invention is to provide a hose connecting device, which is capable of improving the above-mention problems.

In order to achieve the above mentioned objective, a hose connecting device has a connector, an inner locking ring, an outer connector and a tubal body. The connector has an insertion section and an engaging section, the engaging section has a size greater than the insertion section, and the engaging section further has a stopping ring at a top end. The inner locking ring is jacketed onto the engaging section of the connector and abutting the stopping ring of the connector. A lubricating member is sandwiched between the inner locking ring and the stopping ring, the inner locking ring has an outer threaded section and an abutting portion disposed at a bottom end of the inner locking ring and has a size greater than a size of the outer threaded section. The outer connector has one of a female connector and a male connector, and a channel, the channel has a positioning step at a middle portion, an inner threaded section disposed below the positioning step of the channel. The tubal body is jacketed onto the insertion section of the connector.

Other objects, advantages, and novel features of invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
