Abstract
The invention relates to a fast connecting pipe fitting for plastic pipes, which comprises a pipe fitting case and is characterized in that the central part of the inner surface of the pipe fitting case is provided with annular projections at intervals; the inner surfaces of the two ends of the pipe fitting case are respectively provided with a locking plate groove; each locking plate groove is respectively provided with seal ring grooves at both sides; an open-mouth toothed locking spring is mounted in each locking plate groove; and a seal ring is mounted in each seal ring groove. The invention solves the problems that the connecting operation of the existing plastic pipes is complex, labor-costing and time-consuming, and the fast connecting pipe fitting for plastic pipes is suitable for connecting plastic pipes.
Description
Technical field
The present invention relates to the interface unit field of plastic tube, a kind of specifically pipe fitting that connects plastic tube.
Background technique
At present, the Placement of plastic tube mainly contains hot melten type, needs with the hot-melting machine of different size tubing and pipe fitting hot melt to be handled the back connection; Cold jointing type is also arranged, and is exactly to connect with viscose glue, viscose glue is smeared evenly the back is connected on outer pipe wall and the pipe fitting inner wall, and it is just effective after consolidating that viscose glues such as need are hard.No matter be hot melten type or cold jointing type, construction environment required high, need the professional and technical personnel to pass through the special tool operation, complex operation, time-consuming, the human operational error is prone to the shortcoming that causes tie point to leak.
Summary of the invention
The present invention provides a kind of connection pipe fitting that has space protrusion, sealing and locking mechanism for solving loaded down with trivial details, the time-consuming problem of attended operation of present plastic tube.
Technological scheme of the present invention is that a kind of quickly jointed tubular workpieces of plastic tube comprises the pipe fitting housing; Its special way is; Ring-like space protrusion is left at pipe fitting shell inner surface middle part, and the internal surface at pipe fitting housing two end part leaves the locking plate groove respectively, and each locking plate groove both sides is left o-ring groove respectively; The formula band tooth locking reed of beginning to speak is installed in the locking plate groove, seal ring is installed in the o-ring groove.
During use; Tubing is firmly inserted in the pipe fitting housing; Make tubing pass the first road seal ring, the formula of beginning to speak band tooth locking reed and the second road seal ring in the pipe fitting housing successively, till arriving ring-like space protrusion, can't continue to insert to tubing, accomplish effectively and connect.The seal ring distortion that is squeezed can evenly be clogged in the space between tubing and pipe fitting housing, plays the effect that sealing blocks water.The teeth of the formula of beginning to speak band tooth locking reed can embed the outer wall of tubing under the effect of elastic force and tensile force, tubing is locked.
Technique effect of the present invention is; Adopt technique scheme can realize a kind of simple to operate, connect tube connection piece fast; It overcome that existing plastic tube hot melten type connects or glue connect the technical sophistication that exists, to construction environment require high, time-consuming, need shortcoming such as special tool, suit is in the connection use of multiple plastic tubes such as PE class, PPR class, plastic-aluminum class.
Description of drawings
Fig. 1 is a structural front view of the present invention, and the accompanying drawing that makes an abstract.
Fig. 2 is the structural front view of formula band tooth locking reed of beginning to speak.
In the drawings, 1 begin to speak formula band tooth locking reed, 2 seal rings, 3 o-ring grooves, 4 locking plate grooves, 5 space protrusion, 6 tubing, 7 pipe fitting housings.
Embodiment
Embodiment further specifies the present invention below in conjunction with accompanying drawing.
Shown in figure; Ring-like space protrusion 5 is left at pipe fitting housing 7 internal surfaces middle part; The internal surface at pipe fitting housing 7 two end part leaves locking plate groove 4 respectively; The both sides of each locking plate groove 4 are left o-ring groove 3 respectively, and the formula band tooth locking reed 1 of beginning to speak is installed in the locking plate groove 4, and seal ring 2 is installed in the o-ring groove 3.
During use; Tubing 6 is firmly inserted in the pipe fitting housing 7; Make tubing 6 pass the first road seal ring 2, the formula of beginning to speak band tooth locking reed 1 and the second road seal ring 2 in the pipe fitting housing 7 successively, till arriving ring-like space protrusion 5, can't continue to insert to tubing, accomplish effectively and connect.Seal ring 2 distortion that is squeezed can evenly be clogged in the space between tubing 6 and the pipe fitting housing 7, plays the effect that sealing blocks water.The teeth of the formula of beginning to speak band tooth locking reed 1 can embed the outer wall of tubing 6 under the effect of elastic force and tensile force, with tubing 6 lockings.
Claims (1)
1. the quickly jointed tubular workpieces of a plastic tube; Comprise the pipe fitting housing; It is characterized in that: ring-like space protrusion is left at pipe fitting shell inner surface middle part, and the internal surface at pipe fitting housing two end part leaves the locking plate groove respectively, and each locking plate groove both sides is left o-ring groove respectively; The formula band tooth locking reed of beginning to speak is installed in the locking plate groove, seal ring is installed in the o-ring groove.
