Specific implementation mode
Invention is further described in detail below in conjunction with the accompanying drawings.
Embodiment 1：
With reference to shown in Fig. 2, the invention discloses a kind of hose connection device, including pipe fitting, the pipe fitting is by even
Socket part, outer-hexagonal fixed plate and threaded fixed part composition, are equipped with outer diameter between the interconnecting piece and outer-hexagonal fixed plate
Less than the collet threaded section 2 of outer-hexagonal fixed plate, the interconnecting piece spaced pipe and taper retaining by along end
Ring is formed by connecting, and the outer diameter of the taper retaining ring is less than collet threaded section 2, and the interconnecting piece is externally provided with clamp nut 1.
With reference to shown in Fig. 3,1 inner wall of the clamp nut is made of shiny surface and flank, and wherein the length of flank is super
2/3 is crossed, conical socket 11 is equipped between the shiny surface and flank, the oblique angle of the conical socket 11 is more than taper retaining
The oblique angle of ring is provided with dead ring 4 between the clamp nut 1 and interconnecting piece.
In use, with reference to shown in Fig. 4, this hose connection device is connect by interconnecting piece with the inner wall of hose 5,5 sets of hose
Dead ring 4 is sleeved on 5 outer wall of hose again after outside interconnecting piece, then clamp nut 1 is installed again, clamp nut 1 is along hose 5
Outer wall and be inserted in interconnecting piece, then connect with collet threaded section 2 by internal thread, when rotation is to thread root, clamp nut 1 and
The outer wall of hose 5 compresses, and dead ring 4 can be filled the gap between 5 outer wall of clamp nut 1 and hose, hose 5 is reliably fixed,
After installing, from the appearance, hose 5 is stretched out from clamp nut 1.
Embodiment 2：
Difference from example 1 is that the interconnecting piece rises along end is arranged in sequence with the first pipe 61, first
Taper retaining ring 62, the second pipe 63, the second taper retaining ring 64 and third pipe 65, due to there are two taper retaining ring and
Outer diameter is more than the internal diameter of hose, and effective sealing can be achieved in this way.The first taper retaining ring 62 and the second taper retaining
64 length of ring is identical, and the length of second pipe 63 is more than third pipe 65, and the length of second pipe 63 is more than first
Pipe 61, between the first taper retaining ring 62 and the second pipe 63 and the second taper retaining ring 64 and third pipe
Transition pipe 66 is equipped between 65, transition pipe 66 makes the maximum outer circle of taper retaining ring become plane, can prevent in this way
Scratch hose inner wall.The transition pipe 66, the first taper retaining ring 62 are identical with the outer diameter of the second taper retaining ring 64, described
The length of transition pipe 66 is less than the first pipe 61, since taper retaining ring is in hose approach axis（Illustrate left end）It is oblique
Face, is convenient to the insertion of hose, and right side is to face directly, can effectively anti-hose loosen.
Embodiment 3：
Difference from example 1 is that the oblique angle of the first taper retaining ring 62 and the second taper retaining ring 64
Oblique angle for 15 ± 5 ° of conical sockets 11 is 30 ± 5 °, preferably, the oblique angle of taper retaining ring is 15 °, conical socket
11 oblique angle is 30 °, and the oblique angle of conical socket 11 is more advantageous to more than taper retaining ring compresses hose wall surface, the two differential seat angle phase
The more big then fastening effect of difference is better.The junction of the conical socket 11 and shiny surface is arc surface, which can effectively prevent
Only scratch hose outer wall.
Embodiment 4：
Difference from example 1 is that 61 outer diameter of the first pipe and institute's 5 internal diameter phase of hose to be mounted
Together, 1 internal diameter of the clamp nut is identical as institute's 5 outer diameter of hose to be mounted, in addition, the first taper retaining ring 62, the second pipe
63, the sum of the second taper retaining ring 64, length of third pipe 65 and transition pipe 66 and flank and taper in clamp nut 1
The length of groove 11, after these measures can guarantee that clamp nut 1 is installed, arc surface position compresses hose and taper retaining ring,
It realizes excellent sealing, and prevents hose from slipping.
Embodiment 5：
Difference from example 1 is that the dead ring 4 is polytetrafluoroethylene ring, polytetrafluoroethylene (PTFE) ring material
Fillable gap between hose outer wall and clamp nut makes hose be reliably fixed.
The screw thread of the fixed part is straight thread or taper thread, and straight thread only provides fastening force, needs other sealings
Structure needs that annular groove, the mounting O-shaped sealing ring 3 in annular groove is arranged in the end face of outer-hexagonal fixed plate in this way；Taper thread can
To be sealed to junction by the occlusion between external screw thread and internal thread, taper thread need when sealing using fluid sealant or
Other sealing materials.
When replacing hose, clamp nut is backed out, is scratched the polytetrafluoroethylene ring outside hose and hose with blade, it will be soft
Pipe is removed from taper retaining ring, and the hose more renewed is reinstalled.
The above-described embodiments merely illustrate the principles and effects of the present invention, and the embodiment that part uses, for
For those skilled in the art, without departing from the concept of the premise of the invention, can also make it is several deformation and
It improves, these are all within the scope of protection of the present invention.
