State housing and be provided with the anticreep groove abutted with anti-delinking part.
Protruding anti-delinking part is embedded in anticreep groove, is completely embedded with housing.When metal tube is by pulling force outwardly, anticreep
Portion abuts with housing, is avoided that metal tube is deviate from；By hot water in pipeline, when outer silk straight joint is heated, though metal tube and shell
Body separates, and anti-delinking part also can prevent metal tube from deviating from, it is ensured that the normal use of outer silk straight joint.
This utility model is further arranged to: described housing and the surface of metal tube junction are provided with some circumferentially sides
To the projection being spacedly distributed.
Projection adds the thickness of housing and junction, anti-delinking part, makes housing increase the support force of anti-delinking part, the most convex
Block also has increases the effect of frictional force, and user is difficult to when operating housing skid.
This utility model is further arranged to: the surface of described shell end is provided with some to be divided the most at equal intervals
The reinforcement of cloth.
Reinforcement adds the structural strength of shell end, it is to avoid housing ruptures in use, it is ensured that outer silk straight joint
Safety during use, reinforcement also makes to be difficult to during outer silk straight joint horizontal positioned roll simultaneously, the fortune of convenient outer silk straight joint
Defeated.Reinforcement and projection have difference in height, add the frictional force of reinforcement and protruding junction, when carry out outer silk straight joint with
When external module is attached, user can pass through reinforcement with projection junction as stress point, operates housing.
This utility model is further arranged to: be provided with groove between adjacent described reinforcement.
Groove adds the contact area of user and housing, can further facilitate user and operate housing, recessed
The design of groove also saves the material of housing, reduces production cost.
This utility model is further arranged to: described reinforcement abuts with projection at surface of shell.
Reinforcement abuts with projection, it is to avoid producing gap, integral structure further enhances the structural strength of housing, with
Time also make housing more attractive.
This utility model is further arranged to: described screw thread is provided with rake tooth.
Having in outer tube and seal the female thread coordinated, when silk straight joint is fixed outside, rake tooth supports with female thread
Connecing, rake tooth adds screw thread and the contact area of Threaded Connector Coupling in outside, tightr time threaded.
This utility model is further arranged to: described reinforcement is provided with the press section of arc.
The arc press section being arranged on reinforcement, while having reinforcement shell structure, it is simple to user grips
Housing, more laborsaving when carrying out rotation process.
This utility model is further arranged to: described housing is provided with latch for the inner surface being connected with outer tube.
When outer tube is connected with housing, latch has position-limiting action to outer tube, it is to avoid exterior tube during use
Part is deviate from, it is ensured that the normal use of outer silk straight joint.
By using technique scheme, this utility model has the advantages that between metal tube and plastic fastening
Being completely embedded, metal tube is not easy abjection.
Compared with prior art, the utility model has the advantage of: sound construction, length in service life, easy to operate.
