Description
Technical field
This utility model relates to Anti-extrusion hoop component at a kind of tubing auxiliary, particularly PVC socket joint.
Background technology
PVC has from features such as heavy and light, corrosion-resistant, compressive resistance is high, safe readies, receives engineering circles always
Favorable comment.In recent years, under the pulling of rapid economic development, PVC pipeline development is very rapid, applies more widespread.PVC exists
Executing man-hour requirement to be connected with each other by some tubing according to pipeline length, adjacent tubing junction typically uses sealing ring socket joint even
Connect, for preventing from disengaging at bell socket, generally require and clip is set at tubing bell socket.At present, common clip exists
Problem is, when pipeline interior pressure run, particularly non-buried under the conditions of, lack soil layer wipe resistance, clip is at External Force Acting
Dislocation, slip phenomenon the most easily occur, it is impossible to playing anticreep effect at pipeline spigot-and-socket, cause tubing to leak.
Utility model content
The purpose of this utility model is the drawback for prior art, it is provided that one can improve clip and PVC
Between frictional force, thus PVC bell socket is played Anti-extrusion clip group at the PVC socket joint of reliable anticreep effect
Part.
Problem described in the utility model realizes with following technical proposals:
Anti-extrusion hoop component at a kind of PVC socket joint, including two sets symmetrically arranged card hoop body and connection two set card
Several pull bars of hoop body, described each set card hoop body is made up of two pieces of the most involutory half hoops respectively, and each half hoop is semi-circular, half hoop
Inner surface pawl is set, pawl touches with PVC outer surface, and pawl incline direction is in opposite direction with what tubing disengaged.
Anti-extrusion hoop component at above-mentioned PVC socket joint, the middle part of each half hoop excircle is provided with pull bar and connects
Ear, is provided with tie rod hole at pull bar engaging lug；The two ends of each half hoop are provided with pull bar half-connection ear, be provided with and draw at pull bar half-connection ear
Bar half bore and docking bolt hole.
Anti-extrusion hoop component at above-mentioned PVC socket joint, described pawl along the circumferential direction connects at the inner surface of each half hoop
Continuous distribution.
Anti-extrusion hoop component at above-mentioned PVC socket joint, described pawl each half hoop inner surface in a circumferential direction
Discontinuously distribution.
Anti-extrusion hoop component at above-mentioned PVC socket joint, described pull bar arranges four, and the upper and lower side of each pull bar is provided with lock
Jack panel.
This utility model designs, described hoop component for solving to improve the problem of bonding strength at PVC socket joint
Including two set symmetrically arranged card hoop bodies and four pull bars that two set card hoop bodies are reliably connected.For preventing card hoop body from making at pressure
Using lower dislocation, the inner surface at each card hoop body is provided with pawl.This utility model in use, respectively overlaps card hoop body and PVC
Closely obvolvent, the setting of pawl considerably increases the adhesion of card hoop body and tubing, effectively prevents the dislocation of card hoop body, slides, makes
At tubing bell and spigot, relative position is reliably fixed, and has well ensured PVC in the pressure limit that PVC can bear
Under the conditions of non-buried pressure-bearing uses, bell and spigot junction does not falls out.

Detailed description of the invention
Referring to Fig. 1, this utility model includes the two upper and lower symmetrically arranged card hoop bodies 1 of set and connects the several of two set card hoop bodies
Pull bar.Often set clip is clamped on the upper and lower sides of PVC bell and spigot 2 respectively, and the two ends of pull bar are each passed through each set card hoop body, by
It is arranged on the locking nut of each tie rod end by draw lever locking.This utility model pull bar 3 is provided with four altogether.
Referring to Fig. 1-Fig. 3, often set card hoop body is made up of two pieces of the most involutory half hoops respectively, and each half hoop is semi-circular, and two
Annular card hoop body is constituted after block half hoop is involutory.The internal diameter of card hoop body mates with the external diameter of PVC 4.For increase card hoop body with
Frictional force between PVC, the inner surface in half hoop 1-1 arranges pawl 1-4, and pawl directly connects with the outer surface of PVC 4
Touching, pawl incline direction is in opposite direction with what tubing disengaged.After pawl is set, considerably increase the knot of card hoop body and PVC
Make a concerted effort, effectively prevent the dislocation of card hoop body, slide, make relative position at PVC bell and spigot reliably fix.
Fig. 4, Fig. 5 show two embodiments of the present utility model, and in embodiment illustrated in fig. 4, pawl 1-4 is in half hoop 1-1
Inner surface is distributed continuously in the circumferential direction；In embodiment illustrated in fig. 5 pawl 1-4 at the inner surface of half hoop 1-1 in being discontinuously distributed shape
State, this interrupted distribution of pawl beneficially card hoop body eliminates what PVC surface locally minute protrusions or deformation caused
Adverse effect.
Referring to Fig. 1, Fig. 2, Fig. 4, the middle part of each half hoop excircle is provided with pull bar engaging lug 1-2, pull bar engaging lug
Place is provided with tie rod hole；The two ends of each half hoop are provided with pull bar half-connection ear 1-3, are provided with pull bar half bore and right at pull bar half-connection ear
Connecting bolt hole 1-5.
When this utility model uses, respectively at the upper and lower sides of PVC bell and spigot by involutory for two half hoops, to connecting bolt
Penetrate bolt in hole and lock, making card hoop body and the tight obvolvent of PVC；Then penetrate four at upper and lower two set card hoop bodies to draw
Bar, and by locking nut by draw lever locking.
Onsite application shows, uses this utility model can significantly improve the bonding strength of PVC bell and spigot, at PVC
In the pressure limit that tubing can bear, even under the conditions of the non-buried pressure-bearing of PVC uses, bell and spigot junction is the most not
Can deviate from.
