Abstract
The utility model discloses the attachment means of a kind of hard tube, including hard tube fastener female, hard tube fastener male；Described hard tube fastener female is provided with screwed hole and runs through the through hole of hard tube fastener female, one end of described hard tube fastener male is provided with lobe and runs through the guide hole of hard tube fastener male, described lobe is that cylindrical thread couples with described screwed hole, hard tube passes through hole and guide hole, described lobe front end is provided with arc surface, described screwed hole is provided with the conical surface corresponding with described arc surface, by the described conical surface, arc surface carries out extruding to cause hard tube fastener male to deform thus locked by hard tube, thus reach and the coupling of hard tube.This utility model carries out extruding by the conical surface of screwed hole to lobe nose circle cambered surface and causes hard tube fastener male to deform, thus hard tube is locked, thus reach and being fixedly connected of hard tube, this connecting mode, easy for installation, coupling arrangement is not easy to come off with hard tube and good sealing effect.
Description
Technical field
This utility model relates to a kind of attachment means, more specifically refers to the attachment means of a kind of hard tube.
Background technology
In prior art, the hard tube connecting mode on market is to use back taper joint to couple mostly, back taper joint
Couple installation inconvenience with hard tube, couple insecure between hard tube, easily come off, and back taper joint couples
This mode needs sealing member, sealing member small volume easily drop loss and also sealing effectiveness is not fine.
Therefore, it is necessary to develop novel hard tube attachment means, to reach easy for installation, the effect of good airproof performance
Fruit and be not easy to come off.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, it is provided that the connection dress of a kind of hard tube
Put.
For achieving the above object, this utility model is by the following technical solutions:
The attachment means of a kind of hard tube, including hard tube fastener female, hard tube fastener male；Described hard tube fastener
Female is provided with screwed hole and runs through the through hole of hard tube fastener female, and one end of described hard tube fastener male is provided with convex
The portion of rising and the guide hole running through hard tube fastener male, described lobe is that cylindrical thread couples with described screwed hole,
Hard tube passes through hole and guide hole, and described lobe front end is provided with arc surface, and described screwed hole is provided with described
The conical surface that arc surface is corresponding, the conical surface being provided with by described screwed hole is provided with arc surface to lobe front end and enters
Row extruding causes the deformation of hard tube fastener male thus is locked by hard tube, thus reaches and being fixedly connected of hard tube.
Its further technical scheme is: described through hole is corresponding and in the same size with described guide hole position.
Its further technical scheme is: it is 3-5mm that described lobe front end is provided with the arc radius of arc surface.
Its further technical scheme is: the gap between described hard tube and hard tube fastener male is less than 0.1mm.
This utility model compared with prior art provides the benefit that: the company of a kind of hard tube of this utility model
Connection device, by hard tube fastener female hard tube fastener male carried out extruding cause the deformation of hard tube fastener male from
And hard tube is locked, to reach and being fixedly connected of hard tube, this connecting mode, easy for installation, couple dress
Put and be not easy to come off with hard tube and good sealing effect.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand this reality
Use new technique means, and can be practiced according to the content of description, and in order to make this practicality new
Above and other purpose, feature and the advantage of type can become apparent, below especially exemplified by preferred embodiment,
And coordinate accompanying drawing, describe in detail as follows.

Detailed description of the invention
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment to this reality
It is further described by novel technical scheme and illustrates, but be not limited to this.
Specific embodiment as shown in Figure 1, the attachment means of a kind of hard tube of this utility model, including hard tube
Fastener female 20, hard tube fastener male 30；Hard tube fastener female 20 is provided with screwed hole 201 and runs through hard tube fastener
The through hole 202 of female 20, one end of hard tube fastener male 30 is provided with lobe 301 and runs through hard tube fastener male
The guide hole 302 of 30, lobe 301 couples for cylindrical thread with screwed hole 201, and hard tube 10 is through through hole 202
With guide hole 302, lobe 301 front end is provided with arc surface, and screwed hole 201 is provided with the cone corresponding with arc surface
Face, the conical surface being provided with by screwed hole 201 is provided with arc surface to lobe 301 front end to carry out extruding and causes hard tube
Fastener male 30 deforms thus is locked by hard tube 10, thus reaches and being fixedly connected of hard tube 10.
Screwed hole 201 surrounding is provided with female thread structure along wall, is provided with and screwed hole 201 outside lobe 301
Corresponding external thread structure, screwed hole 201 and lobe 301 are coupled by cylindrical thread；Through hole 202 He
Guide hole 302 position is corresponding and in the same size；Lobe 301 front end is provided with the arc radius of arc surface
3-5mm；Gap between hard tube 10 and hard tube fastener male 30 is less than 0.1mm；Hard tube 10 is through hard tube fastener
Through hole 202 that female 20 is provided with and the guide hole 302 that hard tube fastener male 30 is provided with, by lobe 301 outside
The female thread that the external thread structure that side is provided with is provided with along wall with screwed hole 201 surrounding is connected, and passes through hard tube
The conical surface that in fastener female 20, screwed hole 201 is provided with is to hard tube fastener male 30 protrusions portion 301 nose circle cambered surface
Carrying out extruding causes hard tube fastener male 30 to deform, thus is locked by hard tube 10, thus reaches and hard tube 10
Being fixedly connected, hard tube fastener male 30 other end couples with flexible pipe or passes through thread connection with other devices.
In sum, this utility model is public to hard tube fastener by the conical surface of screwed hole in hard tube fastener female
Head protrusions portion nose circle cambered surface carries out extruding and causes hard tube fastener male to deform, thus is locked by hard tube, from
And reach and being fixedly connected of hard tube, this connecting mode, easy for installation, coupling arrangement is not easy and hard tube
Come off and good sealing effect.
Above-mentioned only further illustrate technology contents of the present utility model with embodiment, in order to Du Zhegeng
Easy to understand, but do not represent embodiment of the present utility model and be only limitted to this, any according to this utility model
The technology done extends or recreation, all by protection of the present utility model.Protection model of the present utility model
Enclose and be as the criterion with claims.
