The plastic film capicitor of water channel drain is mostly soft structures, and end is light wall straight tube, can not with sewer pipe joint into
The stable connection of row, increase swivel nut and be connected with the external screw thread of sewer pipe joint bottom, of high cost, installation and removal are more more
There is inconvenience, and part downcomer, there is no external screw thread, common plastic film capicitor can not be attached with the downcomer of light wall,
It needs to improve.
Invention content
The purpose of the present invention is to provide a kind of socket self-locking bellowss, realize socket and self-locking with downcomer, are promoted
Convenience and structural stability are installed.
For this purpose, the present invention uses following technical scheme：
A kind of socket self-locking bellows, including：From lock set, bellows body and pipe fitting, the pipe fitting is arranged in wave
The one or both ends of line tube body, it is described to be embedded in pipe fitting from lock set, it is described from lock set include fixed ring, pivoted housing,
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 both 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 passive sphere is arranged in the end of the second lever.
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 integration is welded and fixed knot
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.
Beneficial effects of the present invention：A kind of socket self-locking bellows, when downcomer is inserted in the pipe fitting of bellows body end,
Downcomer outer wall contacts with spherical surface shield and increases friction, and forces and moved outside active sphere, the outer shipper pole dynamic first of active sphere
The swing of lever and the second lever, so that moving in passive sphere and corresponding pipe fitting inner wall being forced to squeeze outside downcomer
Wall realizes that the self-locking to downcomer, installation facility avoid Automatic-falling problem, improve the stability used.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the partial enlarged view of part A in Fig. 1.
Specific implementation mode
The technical solution further illustrated the present invention to Fig. 2 and by specific embodiment with reference to Fig. 1.
A kind of socket self-locking bellows, including：From lock set, bellows body 1 and pipe fitting 2, the setting of the 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 facility.
Described includes fixed ring 3, pivoted housing 4, active sphere 7 from lock set and passively 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.
4 outer circle both sides of the pivoted housing are provided with the first lever 5 and the second lever 10, and first lever, 5 oblique point tube connects
First 2 endoporus, 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 the 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 passive sphere 8 is arranged in the end of the second lever 10.
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
It according to lever principle, is moved in passive sphere 8 and 2 inner wall of corresponding pipe fitting is forced to squeeze 11 outer wall of downcomer, realized to downcomer
11 self-locking, installation facility, avoids Automatic-falling problem, improves the stability used.
The spherical surface shield 6, bellows body and pipe fitting 2 are integrated soft plastic structure, and flexible PVC modeling may be used
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
Self-locking is realized in the small size swing of one lever 5 and the second lever 10 in pipe fitting 2.
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
Squish area of 2 inner wall of pipe fitting to 11 outer wall of downcomer so that dotted extruding becomes planar extruding, promotes self-locking stability.
The above content is only presently preferred embodiments of the present invention, for those of ordinary skill in the art, according to the present invention
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 to the present invention
Limitation.
