Background technology
Teflon hose is also referred to as PTFE tube, polyfluortetraethylene pipe, can fit with chemical resistance without adhesiveness, low friction etc.
Good characteristic.Teflon hose generally includes two layers of pipe and is coaxially arranged in practical applications, due to the table of Teflon hose
Face can very little, friction coefficient it is relatively low, it is poor with the bonding force of outer layer engineering plastics, be easy in post-processing two layers in axial direction
Detach from, it is serious internal layer to be made to extract out, also bring puzzlement to subsequent production.
Utility model content
Above-mentioned to solve, the utility model adopts the following technical solution：
A kind of Teflon hose, including inner tube and the outer tube for being set to inner tube periphery；Said inner tube is arranged with outer coaxial tube；
The outer surface that said inner tube is contacted with outer tube is provided with several first grooves, and the axis of first groove and the axis of inner tube are flat
Row；It is formed with the first occlusion portion between two neighboring first groove；First occlusion portion include head and with head one at
The root of type；The section on the head is ellipse, and the both ends of the major cross-sectional axis line on the head extend respectively to and corresponding first
First groove of occlusion portion both sides；The width in the section of the root is that intermediate narrow both ends are wide.
Preferably；The outer surface of said inner tube is additionally provided with the second groove；Second groove is opened in described first and stings
The head in conjunction portion；Several pillars are set in first groove, the first groove is fixed at the bottom end end of pillar, and top extends to interior
The outer surface of pipe.The top of pillar is the arcwall face of indent.
Preferably；Second groove in the shape of a spiral branch in the outer surface of inner tube.
Preferably；The inner surface that the outer tube is contacted with inner tube is provided with several third grooves；Two neighboring third groove
Between be formed with the second occlusion portion；First occlusion portion is located in third groove；It is recessed that second occlusion portion is set to first
In slot.
Preferably；The shape of first occlusion portion is identical as third groove；The shape and first of second occlusion portion
Groove is identical.
The beneficial effects of the utility model：
Compared with prior art,
Teflon hose described in the utility model passes through on the head of inner tube the first occlusion portion of setting and the first occlusion portion
Cross section is ellipse, can be so engaged to outer tube by head after outer tube is fixed with inner tube, and then prevent inner tube
There is a situation where detach.
Description of the drawings
Fig. 1 is a kind of Teflon hose schematic cross-section in specific embodiment of the utility model.
Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further：
Referring to Fig.1, a kind of Teflon hose, including inner tube 1 and the outer tube 2 for being set to 1 periphery of inner tube.Said inner tube 1 with
Outer tube 2 is coaxially disposed.The outer surface that said inner tube 1 is contacted with outer tube 2 is provided with several first grooves 10.First groove 10
Axis it is parallel with the axis of inner tube 1.The first occlusion portion 11 is formed between two neighboring first groove 10.First occlusion
Portion 11 include head 111 and with 111 integrally formed root 112 of head.The section on the head 111 is ellipse, the head
The both ends of 111 major cross-sectional axis line extend respectively to the first groove 10 with corresponding first occlusion portion, 11 both sides.Can so it make
It obtains the first groove 10 and is located at the width of 111 part of head less than the width positioned at the root 112.The width of first groove 10 is
The distance between two neighboring first occlusion portion, 11 surface.The width in the section of the root 112 is that intermediate narrow both ends are wide, so
So that the side wall of the first groove 10 is not straight, there is certain radian or skewed.
It is preferred that in order to preferably increase the frictional force between inner tube and outer tube, it can be in first groove 10
Several pillars are set, and the first groove 10 is fixed at the bottom end end of pillar, and top extends to the outer surface of inner tube.The top of pillar is
The arcwall face of indent.The part on the top of the pillar is contacted with the inner surface of outer tube, so as to further prevent processed
The case where inner tube is detached with outer tube in journey.
The outer surface of said inner tube is additionally provided with the second groove (not depending on going out in figure).Second groove is opened in described
The head 111 of one occlusion portion 11.Second groove in the shape of a spiral branch in the outer surface of inner tube 1.So that the first groove
10 and second groove form a kind of netted groove, have snap-in force in direction in length and breadth, so as to increase inner tube and outer tube into one
Between frictional force, prevent inner tube from being detached with outer tube.The inner surface that the outer tube is contacted with inner tube is provided with several third grooves
(not marked in figure).The second occlusion portion (not marked in figure) is formed between two neighboring third groove.First occlusion portion
11 are located in third groove；Second occlusion portion is set in the first groove 10, so may make the first occlusion portion 11 and
Two occlusion portions can be mutually twisted fixation, thus the case where preferably preventing inner tube 1 from being detached with outer tube 2.First occlusion
The shape in portion 11 is identical as third groove.The shape of second occlusion portion is identical as the first groove 10.
In conclusion Teflon hose described in the utility model in inner tube 1 by being arranged the first occlusion portion 11 and first
111 cross section of head of occlusion portion 11 is ellipse, can so be carried out to outer tube by head after outer tube and inner tube are fixed
Occlusion, and then prevent inner tube there is a situation where detach.
It will be apparent to those skilled in the art that technical solution that can be as described above and design, make various other
Corresponding change and deformation, and all these changes and deformation should all belong to the protection of the utility model claims
Within the scope of.
It should be noted that：Embodiment described above is only the utility model a part of the embodiment, rather than all
Embodiment.The embodiment and "an" of singulative used in the attached claims, " described " and "the" are also intended to
Including most forms, unless context clearly shows that other meanings.
