Example 1:

referring to fig. 1-2, the present embodiment discloses a hose connector, which comprises a male connection head 1 and a female connection head 2 connected by threads. The male connection head 1 comprises: the male head gland 11, the male head tube head 12 and the male head reducing short tube 13, the male head tube head 12 is fixed in the large diameter one end of the male head reducing short tube 13, the male head tube head 12 is located in the cavity of the male head gland 11, the male head reducing short tube 13 is arranged in a penetrating way in a first through hole 111 formed in the middle of the male head gland 11, first saw teeth 112 are formed in the inner wall of the first through hole 111, and second saw teeth 131 matched with the first saw teeth 112 are formed in the outer wall of the male head reducing short tube 13. The connection female 2 includes: the female gland 21, female tube head 22 and female reducing nozzle stub 23, female tube head 22 is fixed in female reducing nozzle stub 23 major diameter one end, female tube head 22 is located female gland 21's cavity, female reducing nozzle stub 23 wears to locate in female gland 21 middle part sets up second through-hole 211, second through-hole 211 inner wall is provided with third sawtooth 212, female reducing nozzle stub 23 outer wall be provided with third sawtooth 212 matched with fourth sawtooth 231.

Specifically, in this embodiment, the cavity of the male gland 11 is provided with internal threads, and the outer wall of the female gland 21 is provided with external threads, which are connected by threads.

Specifically, the male pipe head 12 and the male reducing short pipe 13 are integrally formed, and the female pipe head 22 and the female reducing short pipe 23 are integrally formed.

The male tip 12 is snap-fit with the female tip 22. Specifically, the end face of the male pipe head 12 is provided with a clamping head 14, and the end face of the female pipe head 22 is provided with a clamping groove 24 matched with the clamping head 14.

The water hose connector of the embodiment has triple waterproof effects, and is specifically as follows: first resealing: an annular groove is formed in the end face of the male pipe head 12, and a first sealing ring 15 is embedded in the annular groove; the end face of the female pipe head 22 is also provided with an annular groove, and a second sealing ring 25 is embedded in the annular groove. The first reseal may form a sealing surface for the contact end surfaces of the male tip 12 and the female tip 22. In selecting the first seal ring 15 and the second seal ring 25, it is necessary to make the thickness of the seal rings slightly larger than the depth of the annular groove. And (3) second sealing: a first guide ring 16 is arranged between the inner side wall of the cavity of the male gland 11 and the male tube head 12; a second guide ring 26 is also arranged between the inner side wall of the cavity of the female gland 21 and the female tube head 22.
