Active sphere and passive sphere, the fixed ring and pipe fitting are mutually concentric, and several pivoted housing shape array distributions are described in fixed ring
Pivoted housing outer circle two sides are provided with the first lever and the second lever, the oblique point tube coupler bore of the first lever, the active ball
Body is located at the first lever end and convex is wrapped in active sphere arcuate surface in being provided on pipe fitting inner wall, the pipe fitting inner wall
Spherical surface shield, the second lever point tube connector opening end, the end of the second lever is arranged in the passive sphere.
Wherein, the spherical surface shield, bellows body and pipe fitting are integrated soft plastic structure.
Wherein, the active sphere and passive sphere are respectively steel ball.
Wherein, the quantity of the pivoted housing is no less than 3.
Wherein, first lever, the second lever, pivoted housing, active sphere and passive sphere are that knot is welded and fixed in integration
Structure.
Wherein, first lever and the second lever are mutually concentric.
Wherein, indent is disposed an outwardly facing the arch groove on the inside of pipe fitting on the spherical surface of the passive sphere.
Wherein, the passive sphere is close but not convex in pipe fitting inner wall.
The utility model has the beneficial effects that a kind of self-locking bellows of socket, the pipe that downcomer is inserted in bellows body end connect
It when head, is lauched pipe outer wall and is contacted with spherical surface shield and increase friction, and force and moved outside active sphere, the outer shipper pole of active sphere is dynamic
The swing of first lever and the second lever, so that moving in passive sphere and corresponding pipe fitting inner wall being forced to squeeze downcomer
Outer wall realizes that, to the self-locking of downcomer, installation convenience avoids Automatic-falling problem, improves the stability used.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial enlarged view of part A in Fig. 1.
Specific embodiment
The technical solution of the utility model is further illustrated below with reference to Fig. 1 to Fig. 2 and by specific embodiment.
A kind of self-locking bellows of socket, comprising: from lock set, bellows body 1 and pipe fitting 2, the setting of pipe fitting 2 exists
The one or both ends of bellows body 1, described to be embedded in pipe fitting 2 from lock set, production convenience.
Described from lock set includes that fixed ring 3, pivoted housing 4, active sphere 7 and passive sphere 8, the fixed ring 3 connect with pipe
First 2 is mutually concentric, and 64 annular arrays of pivoted housing are distributed in fixed ring 3, forms 6 self-locking structures for surrounding downcomer 11.
The 4 outer circle two sides of pivoted housing are provided with the first lever 5 and the second lever 10, and the oblique point tube of first lever 5 connects
First 2 inner hole, the active sphere 7 are located at 5 end of the first lever and convex are arranged on 2 inner wall of pipe fitting, 2 inner wall of pipe fitting
There is the spherical surface shield 6 for being wrapped in 7 arcuate surface of active sphere, avoids the exposed problem of rustiness of active sphere 7.Downcomer 11 is inserted in wave
When the pipe fitting 2 of 1 end of line tube body, 11 outer wall of downcomer contacts with spherical surface shield 6 and increases friction, and forces active sphere 7
Outer shifting.
Second lever 10 is directed toward 2 open end of pipe fitting, and the end of the second lever 10 is arranged in the passive sphere 8.
The passive sphere 8 it is close but it is not convex keep 2 inner wall of pipe fitting bright and clean in 2 inner wall of pipe fitting, downcomer 11 is inserted into pipe fitting 2
When, it avoids hindering.First lever 5 and the second lever 10 are mutually concentric, form seesaw structure, when being moved outside active sphere 7, root
According to lever principle, moves in passive sphere 8 and corresponding 2 inner wall of pipe fitting is forced to squeeze 11 outer wall of downcomer, realize to downcomer
11 it is self-locking, installation convenience, avoid Automatic-falling problem, improve the stability used.
The spherical surface shield 6, bellows body and pipe fitting 2 are integrated soft plastic structure, can be moulded using flexible PVC
Material, and 2 internal diameter of pipe fitting is corresponding with 11 outer diameter of downcomer, reduction seepage problem, and soft plastic structure is conducive to the
The small size swing of one lever 5 and the second lever 10 in pipe fitting 2 is realized self-locking.
The active sphere 7 and passive sphere 8 are respectively steel ball, and structural strength is high, first lever 5, the second lever
10, pivoted housing 4, active sphere 7 and passive sphere 8 are that integration is welded and fixed structure, when production, are embedded in pipe fitting 2, structure
Stablize.
Indent is disposed an outwardly facing the arch groove 9 of 2 inside of pipe fitting on the spherical surface of the passive sphere 8, and arch groove 9 increases
2 inner wall of pipe fitting promotes self-locking stability so that dotted extruding becomes planar extruding to the squish area of 11 outer wall of downcomer.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
